Description

The present invention relates to a structure for fixing objects.

The following Patent Document 1 describes a double floor component in which two guide rails are provided on the floor panel and a sliding member moves on the guide rails. A server rack is fixed to the sliding member.

WO2016/088184 publication

In the double floor member shown in Patent Document 1, the range of motion of the sliding member is limited to the two guide rails. As a result, the fixing positions for fixing objects such as server racks to the floor panel are limited to the two guide rails or the area between the two guide rails. In other words, the layout of the objects is limited. On the other hand, if the number of guide rails is increased so that the fixing positions are not limited, the number of parts required to fix the objects to the floor panel increases, and the fixing structure becomes complicated.

In consideration of the above, the present invention aims to provide an object fixing structure that increases the freedom of layout with a simple fixing structure.

The object fixing structure of claim 1 comprises a floor, a clamping member fixed to the floor , a guide rod clamped between the clamping member and the floor and erected from the upper surface of the floor , a movable member arranged at a distance from the floor and movably engaged with the guide rod along the upper surface of the floor, and provided with a fixing portion to which an object placed on the floor is fixed, and a fixing member fixing the movable member to the guide rod.

According to the structure for fixing a placed object of claim 1, the movable member to which the placed object is fixed is fixed to the guide rod by using a fixing member. The guide rod is erected on the upper surface of the floor. In other words, the placed object is fixed to the floor. This prevents the placed object from falling over due to an earthquake or the like.

In addition, the movable member is engaged with the guide rod erected on the upper surface of the floor so as to be movable along the upper surface of the floor. In other words, the movable member can move with the guide rod as a fulcrum when positioning. This allows a wider range of movement with fewer parts compared to the conventional configuration using two guide rails and a slide member that moves linearly along the two guide rails. Therefore, the simple fixing structure allows for greater freedom in the layout of the placed items.
The object fixing structure of claim 2 comprises a floor, a guide rod erected on the upper surface of the floor, a movable member that is engaged with the guide rod so as to be movably disposed along the upper surface of the floor and has a fixing portion to which an object to be placed on the floor is fixed, and a fixing member that fixes the movable member to the guide rod, wherein the guide rod comprises a base portion and a rod protruding upward from the base portion, and the fixing member clamps the base portion between the guide rod and the floor to fix the guide rod to the floor, and comprises a clamping member having a through hole through which the rod is inserted, and the movable member is fixed to the clamping member by a nut screwed onto the rod, and the fixing portion comprises a through hole formed at the tip of the movable member, a support member inserted into the through hole, and a nut screwed into the support member to fix the object.

The object fixing structure of claim 3 is the object fixing structure of claim 2 , in which a plurality of through holes are formed in the floor, and the clamping member is fixed to the floor by a bolt inserted into one of the plurality of through holes.

According to the structure for fixing an object according to claim 3 , the guide rod is fixed to the floor by a fixing member. The fixing member is fixed to the floor by a bolt inserted into one of a plurality of through holes formed in the floor. This allows the guide rod to be positioned at any position on the floor. Therefore, compared to a structure with only one through hole, the degree of freedom in the layout of the object fixed to the fixed portion of the movable member can be increased.

The object fixing structure of claim 4 is the object fixing structure of claim 3 , in which a reinforcing material having a through hole formed therein is fixed to the underside of the floor, and the bolt is inserted into the through hole of the reinforcing material.

According to the structure for fixing an object to be placed on a floor, the bolt for fixing the fixing member to the floor is inserted into the reinforcing material fixed to the underside of the floor. In other words, the fixing member is fixed to the floor in a state stiffened by the reinforcing material. This improves the fixation of the object to be placed on the floor.

The object fixing structure of claim 5 is an object fixing structure described in any one of claims 1 to 4 , wherein the movable member has a long hole formed along the upper surface of the floor, and the movable member is capable of moving along the upper surface of the floor by engaging the guide rod with the long hole.

According to the structure for fixing an object according to claim 5 , the movable member is movable along the upper surface of the floor by engaging the long hole with the guide rod. That is, by moving the movable member while keeping the guide rod engaged with the long hole, the movable member can move linearly or pivotally with the guide rod as a fulcrum.

Therefore, compared to conventional sliding members that move in a straight line along a guide rail, there is a high degree of freedom in the arrangement of the fixed part of the movable member. This allows for even greater freedom in the layout of the objects placed on it.

In one embodiment of the object fixing structure, the fixing member is fixed to the floor at multiple points, and includes a clamping member that clamps and fixes the guide rod between itself and the floor, and a nut that is screwed onto the guide rod and clamps and fixes the movable member between itself and the clamping member.

According to one embodiment of the structure for fixing an object to be placed on a floor, the fixing member includes a clamping member and a nut. The clamping member clamps and fixes the guide rod between the clamping member and the floor, and is fixed to the floor at a plurality of locations. The nut clamps and fixes the movable member between the clamping member and the nut. In other words, the movable member is fixed to the floor via the guide rod and the fixing member. This can improve the degree of fixation of the object to be placed on the floor.
The object fixing structure of claim 6 is the object fixing structure of claim 3, wherein the clamping member has a long through hole through which the bolt is inserted, and the fixed position of the guide rod to the floor can be adjusted by adjusting the position of the clamping member.

In the object fixing structure of claim 7 , the guide rod is a bolt erected on the upper surface of the floor while engaged with a rail fixed to the floor, the fixing member is a nut disposed inside the rail and into which the bolt is screwed to fix the movable member to the rail, and the movable member is engaged with the bolt so as to be rotatable along the upper surface of the floor.

According to the seventh aspect of the object fixing structure, the bolt as a guide rod is engaged with a rail fixed to the floor. Therefore, the bolt can be moved along the rail. Furthermore, the movable member is engaged with the bolt so as to be rotatable along the upper surface of the floor. Therefore, compared to a case in which the movable member cannot be rotatable, the movable range of the movable member can be made wider even when there is only one rail. Furthermore, compared to a case in which there are two rails, the number of parts can be reduced.

The present invention provides an object fixing structure that allows for greater freedom in layout through a simple fixing structure.

[First embodiment]
<Placement object fixing structure>
The object fixing structure according to the first embodiment of the present invention is a floor structure for fixing an object to a floor 10 formed of floor panels 12 shown in Figures 1 (A) to (C) in order to prevent the object placed on the floor from falling over or sliding sideways during an earthquake or the like.

(floor)
The floor 10 is formed by laying floor panels 12 on a slab S. The floor panels 12 are placed on the slab S of the building via support beams 14, forming a so-called double-floor floor 10. A space V between the floor panels 12 and the slab S is used as a space for laying wiring, piping, etc.

The floor panel 12 is formed by reinforcing the back side of the surface material 12A with ribs 12B. The surface material 12A is a roughly square panel with a flat top surface that serves as the walking surface. The ribs 12B are lattice-shaped plates that stand upright downward from the back side of the surface material 12A, and improve the bending rigidity of the surface material 12A in the X and Y directions.

The X and Y directions are perpendicular to each other. When the floor panel 12 is laid on the slab S, the X and Y directions are parallel to the in-plane direction of the slab S.

The surface material 12A and the ribs 12B of the floor panel 12 are molded integrally by aluminum die casting, for example. The floor panel may also be formed using resin.

A plurality of through holes 12C are formed in the surface material 12A. The arrangement and spacing of the through holes 12C are not particularly limited, but in this embodiment, as an example, seven through holes 12C are formed at a predetermined spacing L1 in the X direction, and two through holes 12C are formed at a predetermined spacing L2 in the Y direction.

Two reinforcing members 16 are fixed to the floor panel 12. The reinforcing members 16 are formed, for example, from angle bars, and are fixed to the floor panel 12, i.e., the lower end surface of the rib 12B, with adhesive or the like. The long axis direction of the reinforcing members 16 is arranged along the X direction (the direction in which the majority of the through holes 12C are formed). The reinforcing members 16 are also arranged directly below the through holes 12C. Furthermore, a through hole 16C is formed in the portion of the reinforcing members 16 that is located directly below the through hole 12C.

A nut 18 is fixed to the reinforcing member 16. The nut 18 is welded to the reinforcing member 16 so that its female thread is positioned directly below the through hole 16C. This allows the bolt inserted through the through holes 12C and 16C to be screwed into the female thread of the nut 18. Note that the reinforcing member 16 may be replaced with a steel material such as a flat plate or a channel material.

(Clamping member)
2A, a hat-shaped clamping member 20 is attached to the floor panel 12. The clamping member 20 is a bent plate-like member, and is formed with two fixing portions 20A and a clamping portion 20B.

The fixing parts 20A are the parts that come into contact with the floor panel 12. The clamping part 20B is formed in the center (the position where it is clamped) between the two fixing parts 20A, and is a part that protrudes upward from the fixing parts 20A and is separated from the floor panel 12.

As shown in FIG. 2B, the fixed portion 20A has a long hole 22. The long holes 22 are formed in the fixed portion 20A on both sides of the clamping portion 20B, and are arranged along a single straight line. In addition, the clamping portion 20B has a circular through hole 24.

As shown in FIG. 2A, the clamping member 20 is fixed to the floor panel 12 with the guide rod 30 (described later) sandwiched between the floor panel 12 and the clamping portion 20B. The clamping member 20 is fixed to the floor panel 12 at two points by screwing the bolt 26, which is inserted through the long hole 22 and the through holes 12C and 16C, into the nut 18.

The clamping member 20 is fixed to the floor panel 12 by inserting two bolts 26 into adjacent through holes 12C. In FIG. 2(A), the two bolts 26 are inserted into adjacent through holes 12C (spacing L2) in the Y direction, but as shown in FIG. 5 (described later), for example, the two bolts 26 may be inserted into adjacent through holes 12C (spacing L1) in the X direction.

(Guide rod)
The guide rod 30 is an axial member fixed to the floor panel 12 by the clamping member 20. The guide rod 30 includes a base portion 32 and a rod 34. The base portion 32 is a portion that is clamped between the floor panel 12 and the clamping portion 20B of the clamping member 20. The rod 34 protrudes upward from the base portion 32 and is an axial body on which a male thread is formed. The rod 34 is inserted into the through hole 24.

The material and dimensions of the base 32 are not particularly limited, but in this embodiment, it is made of metal. The guide rod 30 may be formed integrally with the base 32 and the rod 34 using a ready-made or dedicated bolt, etc.

The base portion 32 can be formed, for example, using an elastic material (rubber, etc.). In this case, rattling of the guide rod 30 can be suppressed by forming the height H1 of the base portion 32 to be greater than the distance H2 between the clamping portion 20B and the floor panel 12 (the distance when the clamping member 20 is fixed to the floor panel 12).

Figure 3 (A) shows the state in which the clamping member 20 is fixed to the floor panel 12, and the guide rod 30 is fixed to the floor panel 12 by the clamping member 20. The guide rod 30 is fixed to the floor panel 12 and stands upright on the upper surface of the floor panel 12.

(Movable member)
A movable member 40 is engaged with and fixed to the guide rod 30. As shown in Fig. 3B, the movable member 40 is a long, plate-like member, and has a long hole 42 and a through hole 44 along the axial direction.

The movable member 40 is disposed above the floor panel 12 with the rod 34 of the guide rod 30 engaged (inserted) into the long hole 42. When the rod 34 of the guide rod 30 is engaged into the long hole 42, the movable member 40 can be moved linearly along the long hole 42. The movable member 40 can also be moved in rotation around the rod 34 as an axis.

As shown in FIG. 4, the movable member 40 is clamped between the clamping member 20 and the nut 28 by screwing the nut 28 onto the rod 34 while the rod 34 is engaged with the long hole 42. This fixes the movable member 40 to the guide rod 30. The clamping member 20 and the nut 28 are examples of fixing members in the present invention.

As shown in FIG. 3(A), before the movable member 40 is fixed to the guide rod 30, a support member 50 is inserted into the through hole 44 of the movable member 40. The support member 50 is a connecting member for connecting the movable member 40 to an object M (described later), and includes a base portion 52 and a rod 54. The base portion 52 is the portion that is placed on the floor panel 12. The rod 34 is a shaft that protrudes upward from the base portion 52 and has a male thread formed thereon.

The material and dimensions of the base 52 are not particularly limited, but in this embodiment, it is made of metal. The support member 50 may be integrally formed of the base 52 and the rod 54 using a ready-made or dedicated bolt or the like.

As shown in FIG. 4, a rod 54 is inserted into the through hole 44. With the rod 54 engaged (inserted) into the through hole 44, a nut 56 is screwed onto the rod 54, thereby fixing the support member 50 to the movable member 40.

The through hole 44 is formed at the end of the movable member 40. The end region of the movable member 40 where the through hole 44 is formed and where the support member 50 is fixed may be referred to as the fixed portion 46 in the following description.

An object M, such as a server rack, is fixed to the rod 54 of the support member 50. By screwing a nut 58 into the rod 54, the object M can be placed on the nut 58. This makes it possible to support the weight of the object M. In other words, the support member 50 can be used as a support leg for the object M.

On the other hand, even if support legs for the object M are provided separately, the object M can be fixed to the floor 10 by fixing the object M to the rod 54.

(Action and Effects)
According to the object fixing structure of this embodiment, as shown in Fig. 4, the movable member 40 to which the object M is fixed is fixed to the guide rod 30 using fixing members (the clamping member 20 and the nut 28). The guide rod 30 is erected (fixed) on the upper surface of the floor 10. In other words, the object M is fixed to the floor 10. This prevents the object M from falling over due to an earthquake or the like.

In addition, a movable member 40 is engaged with a guide rod 30 erected on the upper surface of the floor 10 so as to be movable along the upper surface of the floor 10. That is, the movable member 40 can move with the guide rod 30 as a fulcrum when positioning. This allows a wider range of movement with fewer parts compared to conventional sliding members that move in a straight line along a guide rail. Therefore, the simple fixing structure allows for greater freedom in the layout of the placed object M.

In addition, with the object fixing structure according to this embodiment, the movable member 40 is movable along the upper surface of the floor 10 by engaging the long hole 42 with the rod 34 of the guide rod 30. In other words, by moving the movable member 40 while keeping the guide rod 30 engaged with the long hole 42, the movable member 40 can move linearly or pivotally with the guide rod 30 as a fulcrum.

To explain more specifically, as shown in FIG. 5, when the rod 34 of the guide rod 30 is engaged with the long hole 42, the movable member 40 can be moved linearly along the long hole 42 as indicated by the arrow N1. In other words, the movable member 40 can be moved linearly along the upper surface of the floor panel 12.

In addition, when the rod 34 is engaged with the long hole 42, the movable member 40 can be pivoted around the rod 34 as an axis, as shown by the arrow N2. In other words, the movable member 40 can be rotated along the upper surface of the floor panel 12.

In this way, the movable member 40 can be moved linearly and pivotally to ensure a movable range for the fixed part 46.

In addition, according to the object fixing structure of this embodiment, as shown in FIG. 4, the guide rod 30 is fixed to the floor 10 by the clamping member 20. As shown in FIG. 5, the clamping member 20 is fixed with a bolt to one of a plurality of through holes 12C formed in the floor panel 12 of the floor 10. This allows the guide rod 30 to be positioned at any position on the floor 10. Therefore, compared to a configuration with only one through hole 12C, the degree of freedom in the layout of the object M fixed to the fixing portion 46 of the movable member 40 can be further increased.

In addition, the object fixing structure of this embodiment can suppress cross-sectional loss of the floor panel 12. That is, as shown in FIG. 2, the object M can be fixed to the floor 10 simply by forming a through hole 12C in the floor panel 12 for fixing the clamping member 20. As a result, the strength of the floor panel 12 is less likely to be reduced compared to the conventional technology in which a rail is embedded in the floor panel 12. In other words, there is no need to increase the thickness of the floor panel or use a high-strength material.

In addition, according to the object fixing structure of this embodiment, the clamping member 20, which is one of the fixing members that fix the movable member 40 to the guide rod 30, is fixed to the floor panel 12. This allows the movable member 40 to be fixed to the floor panel 12 via the clamping member 20 and the nut 28. This improves the degree of fixation of the object M.

In addition, according to the object fixing structure of this embodiment, two reinforcing members 16 are fixed to the floor panel 12. The reinforcing members 16 are fixed to the lower end surfaces of the ribs 12B, and the bolts 26 are screwed into the nuts 18 fixed to the reinforcing members 16. As a result, during an earthquake, the tensile force acting on the bolts 26 from the object M via the movable member 40, the guide rod 30, and the clamping member 20 is distributed and transmitted to the multiple ribs 12B in the floor panel 12.

In this way, in this embodiment, the stiffness of the floor panel 12 itself can be reduced by using the reinforcing material 16 compared to when a guide rod or the like is fixed directly to the floor panel 12 (when the reinforcing material 16 is not used). Therefore, a general-purpose product can be used as the floor panel for fixing the object M, instead of a dedicated product.

In addition, in this embodiment, as shown in Figures 3(A) and (B), the movable member 40 is moved linearly and in a rotational direction by forming a long hole 42 in the movable member 40, but the embodiment of the present invention is not limited to this. For example, instead of the long hole 42, a plurality of through holes 42A may be formed along the axial direction of the movable member 40. When such through holes 42A are formed, the movable range of the fixing portion 46 is limited compared to when long holes 42 are formed, but the fixing performance of the placed object M is improved because there is less cross-sectional loss in the movable member 40.

In addition, in this embodiment, a floor panel 12 is used in which multiple (14) through holes 12C are formed as shown in FIG. 1(A), but the embodiment of the present invention is not limited to this. For example, any floor panel having through holes formed therein in which the clamping member 20 can be fixed may be used, and at least two through holes may be formed. Even when such a floor panel is used, the movable member 40 can move, so that freedom in the layout of the placed object M can be ensured. In this way, the present invention can be embodied in various forms.

[Second embodiment]
<Placement object fixing structure>
The structure for fixing an object according to the second embodiment of the present invention is a floor structure for fixing an object to a floor 60 shown in FIG.

(floor)
The floor 60 is in a rough floor state on the slab S, or a floor in a state where a self-leveling material or the like is laid on the slab S. A rail 62 is fixed to this floor 60. The rail 62 is a long member having a channel shape with an open top.

In the example shown in FIG. 6, the rail 62 is embedded in the floor 60, but the embodiment of the present invention is not limited to this. For example, the rail 62 may not be embedded in the floor 60, but may be fixed to the upper surface of the floor 60.

(Guide rod, fixing member)
A bolt 70 serving as a guide rod is engaged (horizontally engaged) with the rail 62. As shown in Fig. 7, the bolt 70 is erected on the upper surface of the floor 60 with the rail 62 and a movable member 80 sandwiched between the bolt 70 and a nut 72 serving as a fixing member.

As such, in the present invention, "standing" includes an embodiment such as a bolt 70 that is arranged vertically with a nut 72 screwed in. In other words, the guide rod of the present invention does not necessarily have to be self-supporting.

As shown in FIG. 6, the nut 72 is disposed inside the rail 62. The bolt 70 is screwed into the nut from above. This causes the bolt 70 to engage with the rail 62 in the vertical direction.

(Movable member)
The movable member 80 is a flat plate-like member made of metal, resin, etc. The movable member 80 is engaged with the bolt 70 so as to be rotatable along the upper surface of the floor 60, as shown by the arrow N3 in Fig. 8. In other words, the movable member 80 can rotate along the upper surface of the floor 60 with the bolt 70 as the central axis.

As shown in FIG. 6, the movable member 80 is formed with a through hole 82 and a through hole 84. The through hole 82 passes through the movable member 80 in the vertical direction. The through hole 82 is formed with a thin diameter portion 82A in which the shaft portion of the bolt 70 is disposed, and a thick diameter portion 82B in which the bolt head is disposed. In this way, the through hole 82 is formed with two holes of different diameters (thin diameter portion 82A and thick diameter portion 82B) communicating with each other.

As shown in FIG. 7, when the bolt 70 is screwed into the nut 72, the bolt head of the bolt 70 engages with the step between the small diameter portion 82A and the large diameter portion 82B.

As shown in FIG. 6, the through hole 84 passes through the movable member 80 in the vertical direction. A female threaded portion 84A into which the rod 90 is screwed is formed in the through hole 84. In addition, a large diameter portion 84B having a larger inner diameter than the male threaded portion 84A is formed above the female threaded portion 84A. In this way, the through hole 84 is also formed with two holes of different diameters (the male threaded portion 84A and the large diameter portion 84B) communicating with each other.

The movable member 80 is formed by joining the divided members 80A and 80B. The small diameter portion 82A in the through hole 82 and the female thread portion 84A in the through hole 84 are formed in the divided member 80A. The large diameter portion 82B in the through hole 82 and the large diameter portion 84B in the through hole 84 are formed in the divided member 80B.

The thin-diameter portion 82A, the female thread portion 84A, the thick-diameter portion 82B, and the thick-diameter portion 84B can be formed by penetrating a router into the divided member 80A or the divided member 80B. Therefore, highly accurate cutting work is not required to form the through holes 82, 84, which are two holes with different diameters that communicate with each other. This makes it easy to produce the movable member.

The movable member 80 does not necessarily have to be formed by joining the divided members 80A and 80B, but may be produced as a single piece. In this case, the through hole 84 does not have to have a large diameter portion 84B, and only the female thread portion 84A is formed, which simplifies the process of forming the through hole 84.

As shown in FIG. 7, the object M is fixed to the movable member 80. Specifically, a rod 90 is inserted through the object M. The object M is sandwiched between the nut 92 and the movable member 80. This allows the movable member 80 to support the load of the object M. In other words, the movable member 80 can be used as a support leg for the object M. An earthquake-resistant washer 94 can be placed between the nut 92 and the object M.

(Action and Effects)
In the structure for fixing an object according to the second embodiment, the bolt 70 serving as a guide rod is engaged with the rail 62 fixed to the floor 60. Therefore, as shown by the arrow N4 in Fig. 8, the bolt 70 can be moved linearly along the rail 62.

This allows the movable member 80 to have a wider range of motion than when the movable member is fixed to the through hole 12C formed in the floor panel 12. Therefore, there is no need to form an oval through hole like the long hole 42 of the movable member 40.

Furthermore, as shown by arrow N3, the movable member 80 is engaged with the bolt 70 so as to be rotatable along the upper surface of the floor 60. Therefore, compared to a case in which the movable member 80 cannot rotate, the movable area of the movable member 80 can be made wider even when there is only one rail 62. Also, compared to a case in which there are two rails, the number of parts can be reduced.
