[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a structure for closing a gap formed between a partition and a member penetrating a hole formed in the partition.
[0002]
[Prior art]
For example, a construction machine has a portion where a member (penetrating member) such as a hose or a harness is made to penetrate a partition requiring airtightness. In such a portion, a gap between a hole of the partition and the penetrating member is closed. There is a need to. That is, as shown in the perspective view of FIG. 6, when the pipe 3 is passed through the hole 2 formed in the partition 1, a gap 4 is formed between the partition 1 and the pipe 3. Therefore, when the partition wall 1 needs airtightness, the airtightness can be ensured by covering the gap 4 with a plate-like urethane 5 (FIG. 7) or a rubber plate 6 (FIG. 8). It has been done conventionally.
[0003]
That is, as shown in FIG. 6, when the pipe 3 is passed through the hole 2 formed in the partition 1 made of sheet metal, a gap 4 is necessarily formed between the partition 1 and the pipe 3. In the case of a configuration in which the gap 4 is closed using the urethane 5, as shown in a perspective view of FIG. 7, a hole 5a is formed in the urethane 5 on the plate having an outer shape sufficiently larger than the gap 4 so that the pipe 3 just passes therethrough. At the same time, a notch 5b for introducing the pipe 3 is formed in the hole 5a, and the urethane 5 is mounted on the partition wall 1 so as to pass the pipe 3 through the hole 5a and cover the gap 4. The urethane 5 is fixed to the edge 7 of the hole 2 on one surface side of the partition 1 by being attached with an adhesive.
[0004]
In the case of a configuration in which the gap 4 is closed by using a rubber plate 6, as shown in FIG. 8, the pipe 3 is just inserted into the plate-like rubber 6 having an outer shape sufficiently larger than the gap 4, as in the case of the urethane 5. In addition to forming a hole 6a that only passes through, a notch 6b for introducing the pipe 3 is formed in the hole 6a, and rubber 6 is attached to the partition wall 1 so that the pipe 3 passes through the hole 6a and covers the gap 4. I have. The rubber 6 is fixed to an edge 7 of the hole 2 on one surface side of the partition 1 with a bolt 8.
[0005]
According to such a structure, since the urethane or rubber is a flexible elastic material that can be deformed according to the shape of the pipe 3, the gaps 4 are closed by the urethane 5 and the rubber plate 6, respectively. Airtightness is ensured. It should be noted that such a structure is not limited to construction machines, but may also be present in vehicles such as automobiles, ships, and the like.
[0006]
[Problems to be solved by the invention]
However, in the structure using urethane, since urethane has low strength, even when airtightness is secured as shown in FIG. 9A at the beginning of the installation, the urethane itself breaks and breaks during use. (See part 5c in FIG. 9 (b)), or the adhesive deteriorates with time, and the urethane peels off from the partition walls (see part 5d in FIG. 9 (b)). There are issues.
[0007]
In the structure using rubber, the rubber is stronger than urethane, so that it is not broken. Further, since it is fixed to the partition wall with bolts, it does not peel off. Even if the airtightness is secured as shown in FIG. 10, if the installation position of the pipe is shifted due to vibration or the like, as shown in FIG. 10B, the rubber may be turned up and the gap may not be able to be filled. Further, since rubber cannot be deformed as flexibly as urethane, it is necessary to adjust the position with high accuracy at the time of installation, and there is a problem that installation is difficult.
[0008]
The present invention has been made in view of the above-described problems, and when a penetration member such as a pipe is passed through a partition requiring airtightness, a gap between the partition and the penetration member is closed to improve airtightness. An object of the present invention is to provide a structure for closing a gap between partition walls, which can be secured.
[0009]
[Means for Solving the Problems]
For this reason, the gap closing structure of the partition wall of the present invention, the gap formed between the partition wall and a penetrating member that penetrates the hole formed in the partition wall is formed of a rigid body and fixed to the edge of the hole. Since the elastic body sandwiched between the support member and the penetrating member covers while elastically deforming, the airtightness of the partition wall is secured (claim 1).
[0010]
At this time, by dividing the support and the elastic body into a plurality of parts, the work of installing them is facilitated (claim 2).
Furthermore, by forming a support frame covering the outer periphery of the elastic body on the support, the elastic body is covered by the rigid support frame, and the risk of damage to the elastic body is reduced (claim 3). .
[0011]
Further, by forming a long hole for bolt insertion in the support, and forming a long hole for bolt insertion in the partition, when fixing the support to the partition by bolts, the position is easily adjusted while adjusting the position. A support can be provided on the partition (claims 4 and 5).
In addition, as a method of fixing the support to the partition, there is a structure in which a hook is formed on one side of the support and the hook is hooked to the periphery of the hole to fix the support. When this structure is used, the number of fastening parts can be reduced, the support can be fixed to a place where there is no space for bolt installation, and the support mounting work can be easily performed. .
[0012]
In addition, the support and the elastic body may be bonded to each other with an adhesive (claim 7), or a locking portion for locking the elastic body may be formed on the support (claim 8). The elastic body can be reliably prevented from detaching from the support, and the gap once closed can be prevented from opening again.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In each of the following embodiments, a partition of a construction machine will be described. However, the present invention is not limited to a construction machine, and may be applied to a partition provided in a vehicle such as an automobile or another facility such as a ship.
[0014]
First, a first embodiment of the present invention will be described. 1 to 3 show a gap closing structure according to a first embodiment of the present invention. FIG. 1 is a schematic cross-sectional view thereof, FIG. 2 is a front view thereof (a view taken in the direction of arrow A in FIG. 1), and FIG. Is a schematic cross-sectional view of the modification. 1 to 3, substantially the same portions as those of the conventional example shown in FIGS. 6 to 10 will be described using the same reference numerals.
[0015]
As shown in FIGS. 1 and 2, a hole 2 is formed in a partition 1 made of sheet metal, and a pipe 3 penetrates the hole 2. In the hole 2, a gap 4 is formed between the partition 1 and the pipe 3. The gap closing structure of the present embodiment includes a support member (support) 11 configured as a rigid body made of metal or the like, a urethane gap closing member (elastic body, hereinafter referred to as urethane) 16 mounted inside the support member. And a bolt (fixing member) 14 for fixing the support member 11 to the partition wall 1. Each of the support member 11 and the urethane 16 is formed in two parts, and these are connected to each other with the pipe 3 interposed therebetween, so that the entire outer periphery of the pipe 3 is covered with the urethane 16.
[0016]
In the gap closing structure according to the present embodiment, the support pipe 3 has a horizontal symmetry plane passing through the axis of the support pipe 3 in FIGS. Therefore, the upper part in the figure than the symmetry plane will be described first. Components that are substantially the same above and below the plane of symmetry are denoted by the same reference numerals, and those above the plane of symmetry are marked with an a after the numeral code, and those below the plane of symmetry. The components are described by adding a b after the numeral code.
[0017]
The upper support member 11a includes a mounting portion 9a, which is joined to the partition wall 1 at the edge 7 of the hole 2, and a urethane support portion 10a which stands vertically with respect to the mounting portion 9a. A bolt hole 12a for inserting a bolt is formed in the mounting portion 9a of the upper support member 11a. The partition wall 1 is also provided with bolt holes 13a for inserting bolts. The bolts 14a are inserted into these bolt holes 12a, 13a, and the nuts 15a are fastened to the ends of the bolts 14a, so that the upper support member 11a is formed. Is fixed to the partition 1.
[0018]
Further, a plate-shaped upper urethane 16a having a portion corresponding to the pipe 3 penetrated is adhered to the inner surface of the urethane support 10a with an adhesive. A locking portion 17a for locking the upper urethane 16a protrudes from one end of the urethane supporting portion 10a. The upper urethane 16a is interposed between the urethane support 10a and the pipe 3 in a state where the upper urethane 16a is compressed in the radial direction of the pipe. It is able to follow. Therefore, the upper urethane 16a is always pressed against the outer periphery of the pipe 3 to seal this portion.
[0019]
Further, the outer peripheral portion of the upper urethane 16a is installed in a state of being compressed in the axial direction of the pipe 3 between the partition wall 1 and the locking portion 17a at the edge 7 of the gap 4. Therefore, the upper urethane 16a is always pressed against the edge 7 to seal this portion.
A lower support member 11b, a bolt 14b, a nut 15b, and a lower urethane 16b are installed below the symmetry plane in the same manner as in the upper part of the symmetry plane, and the mounting portion 9b and the urethane support 10b are installed similarly to the upper part. , Bolt holes 12b, 13b, and locking portion 17b are formed respectively. The lower urethane 16b is placed in a state of being pressed against the outer periphery of the pipe 3, the edge 7 of the gap 4, and the upper urethane 16a.
For this reason, the gap 4 is closed by the upper urethane 16a and the lower urethane 16b which are installed facing each other from above and below in the figure.
[0020]
Since the gap closing structure of the partition as the first embodiment of the present invention is configured as described above, the gap 3 is closed by urethane 16 which is a flexible elastic body, and the airtightness of the partition 1 is secured. Will be done. At this time, since the urethane 16 can be elastically deformed at all times, the gap 4 does not open even if the arrangement is slightly shifted due to vibration or the like.
[0021]
Further, when installing this structure, since the support member 11 and the urethane 16 are installed so as to cover the gap 4 so as to sandwich the pipe 3 from above and below, the work of attaching the support member 11 and the urethane 16 to the partition wall 1 is performed. It will be easier.
The urethane 16 is adhered to the urethane support 10 with an adhesive. In the conventional example, a force is easily applied in a direction in which the adhesive is peeled, but in this structure, a force is always applied in a direction in which the adhesive is compressed. As a result, the adhesive does not peel off, and the urethane 16 does not separate from the urethane support 10.
[0022]
In addition, since it is locked by the locking portion 17 and the edge 7 of the gap 4, it can be reliably prevented from being detached from the urethane support portion 10.
In this embodiment, since the divided portions of the support member 11 and the urethane 16 are formed in the same shape with plane symmetry, there is an advantage that the manufacturing cost thereof can be reduced. However, they are formed in the symmetric shape or the same shape. It is not limited.
[0023]
Further, as shown by a two-dot chain line in FIG. 2, for example, a long hole 18 in the horizontal direction is formed in place of the bolt hole (round hole) 12 formed in the support member 11 so that the bolt hole 12 is You may make it possible to absorb the displacement with respect to the bolt hole 13. In this case, the displacement in the vertical direction can be absorbed by the elastic deformation of the urethane 16. However, if a vertical elongated hole 19 is formed instead of the bolt hole (round hole) 13 formed in the partition wall 1, The displacement can be more reliably absorbed. In this case, a gap is formed at a portion where the long hole 18 and the long hole 19 overlap, but this gap can be covered by a washer generally used when tightening the bolt. Alternatively, as shown in FIG. 3, a seal sheet 20 may be interposed between the mounting portions 9a, 9a and the partition wall 1 so as to cover the gap. However, when the seal sheet 20 is interposed, the urethane 16 needs to be installed so as to protrude from the support member 11 so as to close the gap between the partition wall 1 formed by the thickness of the seal sheet 20 and the support member 11. There is.
[0024]
Thereby, the position adjustment of the support member 11 can be easily performed, and by adjusting the support member 11 to an appropriate position, the pipe 3 does not hit against the urethane 16 in a well-balanced manner from each direction. It can be pressed. This makes it possible to set the urethane 16 so that it can reliably follow the movement of the pipe 3 in each direction.
[0025]
Next, a gap closing structure according to a second embodiment of the present invention will be described. 4 and 5 show a gap closing structure according to a second embodiment of the present invention. FIG. 4 is a schematic sectional view thereof, and FIG. 5 is a front view thereof (a view taken in the direction of arrow B in FIG. 4). 4 and 5, the same parts as those in the conventional example shown in FIGS. 6 to 10 are described using the same reference numerals.
A pipe 3 passes through the center of a hole 2 formed in a partition wall 1 made of sheet metal, and a gap 4 is formed between the partition wall 1 and the pipe 3.
[0026]
Also in the present embodiment, the support members (supports) 21 and 28 and the urethanes (elastic bodies) 26 and 31 are formed into upper and lower splits so as to sandwich the pipe 3, and the urethanes 26 and 31 are vertically symmetrical. The members 21 and 28 have different configurations at the top and bottom.
That is, the upper support member 21 includes the mounting portion 22 joined to the partition wall 1 at the edge 7 of the hole 2 and the urethane support portion 23 erected perpendicularly to the mounting portion 22. 21 is fixed to the partition 1 by bolting the mounting portion 22 to the partition 1 through bolts 24 and nuts 25. The urethane support portion 23 is formed in a U-shape in a front view as shown in FIG. 5, and a plate-like portion having a portion corresponding to the pipe 3 is formed on the inner surface of the urethane support portion 23. The upper urethane 26 is attached with an adhesive. A locking portion 27 for locking the upper urethane 26 is formed at the projecting end of the urethane supporting portion 23.
[0027]
On the other hand, the lower support member 28 is provided with a hooking portion 29 that can abut on the rear surface side (the right side surface of the bulkhead in FIG. 3) of the partition wall 1 at the edge of the hole 2, and stands upright to the hooking portion 29. The lower support member 28 is attached to the partition wall 1 by hooking the hook 29 on the periphery of the hole 2.
As shown in FIG. 4, the lower support member 28 is formed in a U-shape in a front view, and a plate-shaped lower urethane having a portion corresponding to the pipe 3 penetrated on the inner surface of the urethane support 30. 31 is attached with an adhesive. Further, locking portions 32 a and 32 b for locking the lower urethane 31 are formed on the inner side surface of the urethane support portion 30 so as to sandwich the lower urethane 31.
[0028]
The urethane support portion 23 of the upper support member 21 and the urethane support portion 30 of the lower support member 28 have left and right connecting flange portions 33 and 34, respectively. 36, and is configured as a support frame 37 surrounding the outer periphery of the upper urethane 26 and the lower urethane 31. The upper urethane 26 and the lower urethane 31 are mounted in a compressed state in the support frame 37 formed as described above, and can elastically deform and follow the vibration of the pipe 3 and the like. It has become. Therefore, the upper urethane 26 and the lower urethane 31 are in pressure contact with the outer periphery of the pipe 3.
The upper urethane 26 and the lower urethane 31 are in pressure contact with the edge of the gap. Therefore, the gap 4 is reliably closed by the upper urethane 26 and the lower urethane 31.
[0029]
Since the gap closing structure of the partition wall as the second embodiment of the present invention is configured as described above, the gap 4 is closed by the urethanes 26 and 31, and the airtightness of the partition wall 1 is ensured. Furthermore, since the support frames 37 are formed on the support members 21 and 28 to cover the outer peripheral surfaces of the urethanes 26 and 31, the protection of the support frames 37 can prevent the urethanes 26 and 31 from being damaged. Further, since the lower support member 28 is fixed to the partition wall 1 by locking the locking portion 29 to the peripheral edge of the hole 2, the number of fastening parts can be reduced, and the support member can be used in a place where there is no space for bolt installation. Can be fixed.
[0030]
Further, when performing the support mounting work, the pipe 3 is previously sandwiched between the support members 21 and 28 and the urethanes 26 and 31, and the flange portions 33 and 34 are temporarily fixed with the bolts 35 and the nuts 36. After the support members 21 and 28 and the urethanes 26 and 31 are moved to the positions (1) and (2), the bolts of the flange portions 33 and 34 and the bolts of the partition wall 1 and the mounting portion 22 are performed. Installation work can be performed easily.
[0031]
Although the lower support member 28 and the partition wall 1 are in direct pressure contact with each other at the hook portion 29, a seal sheet may be interposed between the lower support member 28 and the partition member 1 if necessary.
Although the embodiments of the present invention have been described above, the present invention is not limited to such embodiments, and can be variously modified and implemented without departing from the spirit of the present invention.
[0032]
For example, as the material for filling the gap, a material that easily deforms, such as sponge rubber, can be used other than urethane.
In addition, a rigid body that is not easily deformed, such as plastic or ceramic, can be used as a component for sandwiching urethane, in addition to metal. Further, the rigid body does not need to have a flat plate shape, and can be used by forming a phase according to the installation environment, or by forming it into a net shape or a mesh shape.
[0033]
The means for fixing the support member to the partition may be a rivet or the like in addition to those described in the embodiments, and may be fixed by welding when it is not necessary to remove the support member.
When urethane is adhered to the urethane support, adhesion may be performed by heat welding without using an adhesive.
Also, without using an adhesive for the urethane support, the urethane may be prevented from being detached from the urethane support only by the locking part, and conversely, the adhesive may be formed without forming the locking part in the urethane support. The urethane alone may prevent the urethane from separating from the urethane support. Furthermore, without using an adhesive and a locking portion, the gap between the partition walls of the present invention is closed so as to prevent the urethane from separating from the supporting portion by frictional force caused by urethane pressing against the supporting portion and the pipe. The structure may be configured.
[0034]
Further, the split structure of the support and the elastic body is not limited to a vertically split structure, but may be a left and right split. Alternatively, it may be divided into three or more. Further, it may be configured by mounting upside down.
Alternatively, the support body and the elastic body are not divided, but as an integral structure, a hole for piping is formed in the center of the elastic body, and a cutout is formed from the outer peripheral portion to the hole, so that the inside of the hole of the elastic body is formed. The pipe may be inserted into the elastic body while deforming the elastic body through the cut.
