Description

  The present invention provides a connection member that is advantageous for use in a portion that connects the base material at a right angle when constructing a base of a wall or ceiling of a building using a base material made of a hollow material having a substantially rectangular cross section, and construction About the method.

  The base material such as the body edge and the field edge as the base material of the inner wall and ceiling of the building used wood with a square cross section, but recently, a relatively thin steel plate has been rolled so that the cross section becomes a substantially square. A base material (hollow base material) made of a molded hollow material has been used. Such a hollow base material is widely used because it has high dimensional accuracy and sufficient strength and has good workability.

  When configuring the base of the inner wall or ceiling using a hollow base material, for example, when configuring the base of the inner wall, a runner having a U-shaped cross section is fixed to the floor and the beam. The hollow base material is generally arranged at a predetermined interval (a dimension corresponding to the module dimension), and both ends are fitted into the runner and fixed. In addition, when configuring the base of the ceiling, a member (runner) for attaching the end of the hollow base material to the opposite beam is fixed in advance, and a plurality of hollow base materials are arranged at preset intervals. At the same time, the both ends are generally fitted into the runner and fixed.

  Openings for facility equipment including windows and air conditioners may be formed on the inner wall surface and ceiling surface as described above. For example, a procedure for forming a base in the case of forming an opening on the ceiling surface will be briefly described.

  First, a plurality of hollow base materials (through base materials) are arranged at predetermined intervals, and fixed to runners having both ends fixed to a beam or the like. At this time, the area including the opening portion where the position is set in advance is opened without arranging the base material, and the surrounding conditions (for example, connection conditions including the power source) are taken into consideration in this area. Set the position of the opening.

  Two hollow base materials (passing base materials) are arranged along the edge in the direction orthogonal to the through base material in the opening set in the region, and both ends are connected to the through base material. Next, two hollow base materials (end base materials) are arranged along an edge in a direction parallel to the through base material in the opening, and both ends are connected to the base material. Accordingly, the passing base material and the end base material are arranged on the four sides of the opening, and the periphery of the opening is defined. Further, a hollow base material (adjustment base material) is disposed between the passing base material and the runner. The adjustment base material is fixed to a runner whose one end is fixed to the passing base material and the other end is fixed to the beam.

  As described above, when forming a base using a hollow base material, two hollow base materials may be connected at right angles. In this case, a joint fitting having two pieces formed in a U-shape so as to sandwich the outer surface of the hollow base material and arranging these pieces in an L-shape has been used. However, when this joint fitting is used, there is a problem in that a piece sandwiching the outer surface of the joint fitting overlaps the outside of the hollow base material, resulting in a step corresponding to the thickness of the joint fitting.

  For this reason, there has been proposed a convex mounting bracket having at least one protrusion and an attachment piece extending from a side end of the protrusion (see, for example, Patent Document 1). In this technique, the dimension between both ends of the mounting piece of the mounting bracket matches the width dimension of the hollow base material, and the mounting bracket is fixed to one hollow base material and protruded into the hollow portion of the other hollow base material. It is attached by inserting the part. By setting it as such an attachment structure, it becomes possible to position the side surface of the two hollow base materials connected at right angles in the same plane.

  In the L-shaped joint fitting and the convex fitting fitting described in Patent Document 1, it is possible to connect two hollow base materials arranged at right angles. In this case, joint brackets and mounting brackets are fixed in advance to one connected base material made of a hollow base material, and a connection base material made of a hollow base material that has been cut to a predetermined length is screwed into these brackets. It is connected by fixing or plugging in.

  The position of the opening formed in order to install the equipment on the inner wall surface or the ceiling surface is not strictly set, and generally changes somewhat at the site. For this reason, the length of the two vertical members that define the end of the opening and the length of the horizontal member are accurately set, but the hollow base material disposed between the horizontal member and the runner has an accurate dimension. Since it was difficult to set up and had to be matched to the site, there was a problem that workability was poor.

  On the other hand, in the joint metal fitting that connects two hollow base materials that are orthogonal to each other, a step is generated according to the thickness of the joint metal fitting, so that when the face material is attached to the base, there is a problem that the surface material is uneven.

  In addition, in the mounting bracket described in Patent Document 1, the length dimension (the dimension in the width direction of the hollow base material) of the projection formed between the two mounting pieces is larger than the internal dimension in the width direction of the hollow base material. Even if the size of the structural member is inserted into the mounting bracket, the position in the width direction of the structural member is unstable due to a dimensional difference from the mounting piece. When mounting a structural member in the horizontal direction between a pair of structural members fixed in the vertical direction, if the mounting bracket is fixed in advance in the vertical structural member, the length of the horizontal structural member is In order to solve this problem, it is necessary to form a dimension that can avoid the height of the protrusion of the mounting bracket in order to solve this problem. This causes a problem that the work becomes complicated.

  In addition, the joint bracket and the mounting bracket have a function of connecting two orthogonal hollow base materials, but the function of adjusting the length of the hollow base material disposed between the horizontal member and the runner. There is no suggestion of such a function.

  An object of the present invention is to have a function of adjusting the length of a hollow base material, and a function of positioning the side surfaces of both hollow base materials in the same plane when two orthogonal hollow base materials are connected. It is in providing the connecting member which has, and the construction method of the foundation | substrate using this connecting member.

  In order to solve the above-mentioned problem, the connection member according to the present invention is a connection member used for a portion that connects a connection base material and a connection base material made of a hollow material having a substantially rectangular cross section at a right angle, and a fitting portion, A locking piece attached to one end of the fitting portion, and the fitting portion is fitted inside the connection base material and slides in the longitudinal direction to adjust the fitting length. The engaging piece is configured so that the lower surface of the connected base material and the lower surface of the connecting base material are approximately when the fitting portion is engaged with the upper surface of the connected base material by fitting the fitting portion to the connecting base material. It is configured with a shape that can be located in the same plane.

  Further, in the foundation construction method according to the present invention, at least one of the foundation materials is a to-be-connected base material made of a hollow material having a substantially square cross section, and the base material arranged in parallel with the to-be-connected base material. It is a construction method for connecting a connecting base material made of a hollow material having a substantially rectangular cross section to a connected base material at a right angle, and based on the interval between the connected base material and the base material arranged in parallel in advance Preparing a connection base material having a short length, placing the connection member on at least one end of the connection base material and fitting the fitting portion, Temporarily placed by locking to the outer surface of the connected base material, and in the temporarily placed state, the connection base material is slid along the fitting portion of the connection member to attach the other end to the base material, and then connected. The member is fixed to the base material to be connected.

  The connection member according to the present invention includes a fitting portion and a locking piece attached to one end of the fitting portion, and the fitting portion is formed of a hollow material (hollow base material) having a substantially square cross section. It is configured to be fitted inside the connecting base material and to be able to adjust the fitting length by sliding in the longitudinal direction, with the locking piece fitting the fitting part to the hollow base material Since the lower surface of the joining member and the lower surface of the joined member are positioned in the same plane when engaged with the upper surface of the connected member, the locking piece is engaged with the connected base material. Then, the total length can be adjusted by sliding the connection base material in the longitudinal direction of the fitting portion and the length of the connection base material and the length of the fitting portion.

  For this reason, when the opening is formed on the inner wall surface or the ceiling surface, even if the position of the opening is shifted on the site, the shift can be followed. Accordingly, the degree of freedom of the length dimension of the connecting base material is increased, and there is no need for on-site alignment. Therefore, on-site construction is facilitated and the construction period can be shortened.

  In addition, by engaging the locking piece of the connecting member with one surface of the base material to be connected, the other surface of the base material to be joined and the other surface of the base material to be joined can be positioned on the same surface. Thus, when the face material is attached, the face material is not uneven.

  In particular, when the base is a ceiling, it is possible to support by engaging the locking piece with the upper surface of the base material to be joined, and there is no need for the operator to support it by hand. It becomes easy. For this reason, even if it is a case where a some joint base material is connected with respect to a to-be-joined base material, it can fix after setting the position of each joint base material correctly. Furthermore, even when the position of the bonded base material is changed after the bonding base material is connected to the bonded base material, the bonding base material and the fitting tool can slide in the longitudinal direction. Can respond

  Further, in the foundation construction method according to the present invention, a connection foundation material having a length shorter than the interval between the connected foundation material and the foundation material arranged in parallel in advance is prepared, and at least of the connection foundation material A connecting member is arranged at one end and the fitting portion is fitted, and the locking piece of the connecting member is temporarily locked by being locked to the outer surface of the base material to be connected. By sliding the material along the fitting part of the connecting member and attaching the other end to the base material, and then fixing the connecting member to the connected base material, the distance between the connected base material and the base material Can follow the changes of

  Accordingly, when an on-site opening is formed on the inner wall surface or the ceiling surface, it is possible to easily form a ground that follows the change in the position of the opening. In particular, since the connection base material can be processed at the factory stage, not at the site, smooth work can be realized without any support for on-site construction.

  Hereinafter, the most preferable embodiment of the connection member which concerns on this invention, and the construction method of the foundation | substrate using this connection member is described.

  The connecting member according to the present invention is used when connecting a hollow material (hollow base material, bonding base material) having a substantially rectangular cross section to a hollow base material (bonded base material) arranged at a right angle. It has a degree of freedom in adjusting the length of the base material, and when the base material is engaged with the base material to be joined, the surfaces of both the joint base materials are located in the same plane.

  The hollow base material used in the present invention is a hollow material having a substantially rectangular cross section. In this hollow material, each side constituting the square or the side surface of the surface to be the base surface may be bent to improve the cross-sectional performance. It is a rectangle and can be used. The cross-sectional shape of the hollow material may be either substantially square or substantially rectangular. As such a hollow material, what thin rolls the steel plate is provided, It is preferable to use this hollow material as a hollow base material.

  For example, when a hollow base material is used for a ceiling base, for example, a U-shaped or L-shaped long mounting bracket is attached to beams arranged at both ends of a portion constituting the target ceiling in advance, and a hollow base The material is cut to a length equal to the distance between the mounting brackets, and the hollow base material is arranged with a predetermined interval (for example, an integral multiple of the module size set for the building) and both ends are attached. By fixing to the metal fitting, it is possible to configure the ceiling foundation with a hollow foundation material that is arranged on the ceiling surface with a certain interval.

  The connecting member is disposed at a connection part of two hollow base materials (bonded base material and a bonding base material bonded at a right angle to the bonded base material) to be bonded at right angles. In the case where the length of the bonding base material is not fixed, it is possible to adjust the attachment length of the bonding base material (the distance between the base material to be bonded and the other base material or mounting bracket), which is advantageous. .

  For this reason, the connecting member is fitted inside the hollow base material and slidable in the longitudinal direction to adjust the fitting length, and one side of the fitting portion. When engaged with the surface of the hollow base material to be connected in a state where the fitting portion is fitted to the inside of the hollow base material, the surface to be the ground of both hollow base materials is the same surface And a locking piece configured to be arranged.

  The fitting portion has a function of fitting in the hollow portion of the hollow base material (joining base material) and sliding in the length direction, thereby adjusting the attachment length of the joint base material. For this reason, the fitting part has a length sufficient to exhibit the adjustment function. However, the length of the fitting portion is not necessarily limited, and is preferably a length that can satisfy the adjustment length that can be assumed for the portion to be applied. The general length of the fitting portion is about 20 cm to about 30 cm.

  Since the fitting portion is fitted into the hollow portion of the bonding base material, the size may be smaller than the dimension of the hollow portion of the bonding base material. However, it is preferable that there is no backlash when the fitting portion is fitted into the hollow portion of the bonding base material. For this reason, it is preferable that the cross-sectional shape of a fitting part is a square or a U-shape, and it is preferable that a dimension can be slid with respect to the dimension of the hollow part of a joining base material, without producing a backlash.

  It is possible to demonstrate high bending rigidity and shear strength by making the cross-sectional shape of the fitting part square or U-shaped, and the dimensions should be slightly smaller than the dimensions of the hollow part of the bonding base material Thus, even if the fitting portion and the hollow portion rub against each other to generate sliding friction, and the length of the fitting portion is shortened by sliding in the longitudinal direction, a sufficiently stable base can be configured. Become.

  The locking piece is provided at one end of the fitting portion, and when engaged with the bonded base material, the surface on the side opposite to the locking piece of the connection base material into which the fitting portion is fitted It has a function of positioning the (base surface) on the same surface as the surface (base surface) opposite to the surface with which the engagement piece of the base material to be joined is engaged. The shape and structure of the locking piece are not limited as long as the function can be exhibited.

  For example, as a locking piece, when the fitting portion is fitted into the hollow portion of the bonding base material, the surface on one side of the locking piece (the surface facing the surface of the bonded base material) is below the bonding base material. It is preferable to be configured to be in the same plane as the surface opposite to the ground. By configuring the locking piece in this way, when the fitting portion is fitted into the hollow portion of the bonding base material and the locking piece is engaged with the surface opposite to the lower ground of the bonded base material, The lower ground of both base materials is located on the same plane.

  When the connection member of the present invention is fixed to the base material to be joined, the locking piece may be fastened to the surface opposite to the lower ground of the base material to be joined using screws. However, it is natural that a fixing piece may be provided separately from the locking piece. In particular, when the target base is a ceiling base, the locking piece engages with the upper surface of the base material to be joined, and it may be difficult to operate a tool for screwing the screw. In this case, it is preferable to provide a fixing piece on one side or both sides of the locking piece so as to face the lateral surface (side surface) of the bonded base material.

  How to form the fixing piece is not particularly limited, and it is preferable to set an optimum one in consideration of the shape of the fitting portion and the shape of the locking piece. For example, if the fitting part is formed in a U-shape, the U-shaped web part is extended and bent to form a locking piece and the U-shaped flange part is bent. It is possible to form a fixed piece.

  By configuring the connecting member as described above, the engaging piece can be engaged with the upper surface of the base material to be joined, and the connecting member can be fastened to the base material to be joined by screwing screws into the fixing piece. It is.

  Next, the foundation construction method according to the present invention is an advantageous construction method applied when forming an opening having a dimension larger than the interval dimension of the hollow foundation material disposed on the wall surface or ceiling surface, for example. In particular, by connecting two parallel base materials installed in advance at a right angle by two base materials to be joined, a square opening is formed by the two base materials and the two base materials to be joined. When the part is formed, it is arranged in parallel with the base material, and one end is connected to the base material to be joined, and the other end is connected to, for example, a mounting bracket fixed to the beam. In this case, even when a change in the direction along the base material occurs at the position of the opening, and the interval between the base material to be bonded and the mounting bracket changes, this change can be absorbed. .

  That is, by appropriately setting the length of the fitting portion of the connection member and fitting the fitting portion to the hollow portion of the bonding base material, the fitting portion is slid in the longitudinal direction to be fitted. The fluctuation can be absorbed by adjusting the length. Therefore, by cutting the length of the bonding base material slightly shorter than the length corresponding to the position of the preset opening, the length associated with the actual position of the opening varies. Variations can be adjusted.

  For this reason, a connecting member is disposed at least on one end of the bonding base material, and a fitting portion is fitted, and a locking piece of the connecting member is locked to the outer surface of the bonding base material. After that, the joint base material is slid and fixed so that the other end faces the base material attached to the beam, for example, and the connection member is fixed to the base material to be joined. It is possible to connect to the substrate to be bonded.

  Next, a preferred embodiment of the connecting member will be described with reference to the drawings. FIG. 1 is a diagram for explaining the configuration of the connecting member A according to the present embodiment and explaining the relationship between the bonded base material B made of the hollow base material 10 and the bonding base material C.

  In the drawing, a connecting member A is a member formed of a thin steel plate, and has a fitting portion 1 formed in a U-shape and a locking piece 2 provided at one end of the fitting portion 1. And a fixing piece 3 provided at the end on the same side as the locking piece 2 in the fitting portion 1. Then, the fitting portion 1 is fitted into the hollow portion 11 of the bonding base material C made of the hollow base material 10 to engage the locking piece 2 with the surface 10b opposite to the lower ground 10a of the base material B to be joined. When this is done, the lower ground 10a of both the base materials B and C is positioned in the same plane.

  The fitting portion 1 is formed in a U shape by a web 1a and flanges 1b formed on both sides of the web 1a. The width dimension of the web 1a and the width dimension of the flange 1b in the fitting part 1 are formed so as to be slightly smaller than the dimension of the hollow part of the hollow base material B. Therefore, when the fitting portion 1 is fitted into the hollow portion of the hollow base material B, a large gap is not formed between the two, and it is possible to slide roughly and integrally. It is comprised so that it can be made into. Moreover, in order to make it easy to fit the fitting part 1 in the hollow part 11 of the hollow base material 10, it is preferable to bend | curve slightly so that the front-end | tip part of the flange 1b may mutually approach.

  The length of the fitting part 1 can exhibit an adjustment function corresponding to the sliding length by fitting in the hollow part of the hollow base material B and sliding in the length direction of the fitting part 1 And should not be particularly limited. In this embodiment, the length of the fitting portion 1 is set to about 30 cm. However, this numerical value is merely an example, and can be set as appropriate, such as 20 cm or 40 cm.

  The locking piece 2 has a function of engaging the surface 10b of the bonded base material B and positioning the surface 10a of the bonded base material B and the surface 10a of the bonded base material C on the same plane. In the present embodiment, the web 1a of the fitting portion 1 is extended, and a step having a step substantially the same as the thickness of the surface 10b of the hollow base material 10 is provided between the step 1a and the web 1a. 4.

  Accordingly, when the locking piece 2 is engaged with the surface 10b of the bonded base material B, the upper surface of the web 1a of the fitting portion 1 is flush with the position of the inner surface of the surface 10b of the bonded base material C. Thus, the lower ground surface 10a of the bonding base material B and the bonding base material C are located in the same plane.

  The fixing piece 3 is used when the connecting member A is fixed to the side surface 10c of the hollow base material 10 constituting the bonded base material B, and the flange 1b of the fitting portion 1 corresponds to the step portion 4. And a hole 3a is formed at a predetermined position through which a fixing tool such as a screw (not shown) is inserted.

  Therefore, the fixing piece 3 is brought into contact with the side surface 10c in a state where the locking piece 2 is engaged with the surface 10b of the bonded base material B, and this state is maintained and a screw is inserted into the hole 3a to enter the side surface 10c. By fastening, it is possible to fix the connecting member A to the side surface 10c of the hollow base material 10 constituting the bonded base material B. Then, by sliding the joining member C in the longitudinal direction of the fitting portion 1 of the connecting member A, the distance of the joining base material C from the joined base material B can be appropriately adjusted.

  Next, the base construction method using the joining member A will be described by taking as an example the case of configuring the base of the ceiling. FIG. 2 is a diagram for explaining a configuration of a portion where the joining base material B made of the hollow base material 10 and the joining base material C are joined using the connecting member A. FIG. 3 is a schematic diagram illustrating a structure when an opening for installing an air conditioner is formed on the ceiling surface.

  First, an example of a base that can suitably employ the base construction method according to the present invention will be described with reference to FIG. As shown in the figure, the opening D for installing the embedded ceiling air conditioner is disposed at an optimum position on the ceiling in consideration of air conditioning efficiency and convenience of piping or wiring. In this case, the arrangement position of the base material arranged on the ceiling is not considered, and therefore the ceiling base is formed except for the position of the opening D set in advance.

  That is, a long mounting bracket 31 formed in a U-shape is fixed to the surface of the ceiling 30 facing the beam 30 (only one of which is shown) arranged in parallel, and the mounting bracket 31 is fixed. The hollow base material 10 corresponding to the length between them is disposed with a predetermined interval, and both ends are fixed to the mounting bracket 31, respectively. However, as shown in FIG. 3, the hollow base material 10 is not arranged at a site where the opening D is to be formed, but is opened so as to have a larger interval than the dimension of the opening D. It has become.

  For example, when the hollow base material 10 is disposed with an interval of about 30 cm and the dimension (vertical direction, vertical dimension) in the direction along the beam 30 of the opening D is about 60 cm, the hollow base material The space between the two hollow base materials 10 and the third hollow base material 10 is opened for the opening D so that the inner dimension of 10 can satisfy 60 cm.

  In the case of the present embodiment, the interval between the hollow base materials 10 is about 90 cm, and the internal dimension of the side surface 10c is the size obtained by subtracting the width dimension of the hollow base material 10 from about 90 cm, and this dimension is guaranteed with high accuracy. . For this reason, the to-be-joined base material B which consists of the hollow base material 10 arrange | positioned along the vertical direction of the opening part D can guarantee a fixed length irrespective of the fluctuation | variation of the position of the opening part D. FIG.

  Although the dimension (lateral direction, lateral dimension) of the opening D along the hollow base material 10 is set in advance, as described above, the installation position of the opening D on the ceiling can be changed under various conditions. May be. For this reason, it is possible to guarantee the preset length of the bonding base material Ca made of the hollow base material 10 disposed along the lateral edge of the opening D regardless of the position of the opening D. It is. However, since the installation work of the bonded base material B that defines the longitudinal direction of the opening C is an on-site work, it cannot be excluded that a dimensional error occurs. For this reason, it is preferable that the length of the bonding base material Ca is formed to be shorter than the preset lateral dimension of the opening D, and the connection member A is fitted to at least one end.

  The distance between the opening D and the beam 30 may vary with the change in the position of the opening D, and the length of the hollow base material 10 disposed between the bonded base material B and the beam 30 is as follows. Since there is a possibility that the opening D may change as the opening D varies, the length of the bonding base material Cb made of the hollow base material 10 disposed between the base material B to be bonded and the beam 30 is set in advance in the design stage. The fitting part 1 of the connecting member A, which is formed shorter than the formed length and has the function of adjusting the length, is fitted to at least one end part.

  Next, a construction procedure for arranging the bonding base material B along the opening D formed between the hollow base materials 10 arranged in parallel and arranging the bonding base materials Ca and Cb will be described. . First, the position of the opening D between the hollow base material 10 having both ends fixed to the mounting bracket 31 already attached to the beam 30 is determined.

  After the position of the opening D is determined, two bonded base materials B are arranged along the longitudinal direction of the opening D, and both ends are fixed to the side surface of the hollow base material 10. At this time, since the dimension between the hollow base materials 10 is accurately set as described above, it is not necessary to adjust the length of the base material B to be joined. The fixing method with respect to the material 10 is not particularly limited, and a piece-shaped metal fitting 32 having the same shape as the attachment metal 31 can be used, and the connection member A can also be used.

  After fixing the bonding base material B, two bonding base materials Ca are arranged along the lateral direction of the opening D, and both ends are fixed to the side surface 10c of the bonding base material B facing each other. The length of the bonding base material Ca is formed in advance shorter than the lateral dimension of the opening D, and the fitting portions 1 of the connection member A are fitted to both ends.

  The bonding base material Ca is disposed between the bonded base materials B, the fitting portions 1 fitted to both ends are slid in the longitudinal direction, the connecting member A is pulled out, and the locking pieces 2 are attached to the bonded base material B. Engage with surface 10b. At this time, since the bonding base material Ca is formed to be shorter than the lateral dimension of the opening D, even if the actual lateral dimension of the opening D is shorter than the set dimension, it is possible to cope with a certain degree of error. It is.

  In addition, when the lateral dimension of the actual opening D is larger than the set dimension, a part of the fitting part 1 of the connecting member A that is fitted to the bonding base material Ca is drawn out as the bonding base material Ca. By making it function, it is possible to cope with this change in dimensions. The dimension adjustment allowance does not make the entire length of the fitting portion 1 effective. For example, when the length of the fitting portion 1 is about 30 cm, it is about 10 cm to 15 cm. Therefore, when the connecting member A is fitted to both ends, the length is about 20 cm to 30 cm.

  As described above, the bonded base material Ca is bonded to the bonded base material B in a state where the locking pieces 2 of the connecting member A fitted to both ends of the bonded base material Ca are engaged with the surface 10b of the bonded base material B. It is locked to and will not fall. Therefore, in this state, the dimension from the hollow base material 10 is measured in correspondence with the installation position of the opening D, and is set to a position along the lateral edge of the opening D.

  At this time, since the locking piece 2 of the connecting member A is engaged with the surface 10b of the bonded base material B, the bonding base material Ca and the lower ground surface 10a of the bonded base material B are located on the same plane. As a result, unevenness does not occur on the lower ground 10a.

  After positioning as described above, the screw 5 is inserted into the hole 3a formed in the fixed piece 3 and fastened to the side surface 10c of the bonded base material B. After fixing the connecting member A fitted to each bonding base material Ca to the bonded base material B, the bonding base material Cb is disposed between the mounting bracket 31 attached to the beam 30 and the bonded base material B.

  The connecting member A fitted to one end of the bonding base material Cb is opposed to the connected base material B, and the locking piece 2 of the connecting member A is engaged with the surface 10b of the bonded base material B. . Thereafter, the bonding base material Cb is slid along the fitting portion 1, and the other end is supported by the mounting bracket 31. As a result, the bonding base material Cb is supported at one end by the bonded base material B and at the other end by the mounting bracket 31.

  Next, the arrangement interval of the bonding base material Cb is adjusted so as to be equal to the arrangement interval of the hollow base material 10, and the fixing piece 3 of the connection member A is attached to the side surface 10 c of the bonded base material B with the screws 5 in the same manner as described above. Fasten and fix the other end to the mounting bracket 31.

  As described above, regardless of the change in the installation position of the opening D, it is possible to eliminate the cutting work at the site and smoothly configure the ceiling base.

  In the connecting member of the present invention and the base construction method using the connecting member, when the opening is formed on the wall surface or the ceiling surface, the length of the base material changes due to the change in the position of the opening. It is possible to respond. For this reason, it is possible to eliminate work such as cutting of the base material at the site, which is advantageous when applied to a base of a wall or ceiling.

  In addition, since the surfaces of the two base materials bonded orthogonally are located on the same surface, when the face material is attached to the configured base surface, a surface having excellent aesthetics without forming irregularities is formed. This is advantageous when applied to the base of walls and ceilings.

It is a figure explaining the relationship between the to-be-joined base material which consists of a hollow base material, and a joining base material while explaining the structure of a connection member. It is a figure explaining the structure of the site | part which joined the to-be-joined base material which consists of a hollow base material, and a joining base material using a connection member.
