Description

  TECHNICAL FIELD The present invention relates to a guard structure for preventing a fork of a forklift from hitting a wall to damage the wall.

  2. Description of the Related Art When constructing a wall such as an outer wall or an indoor partition wall in a building such as a building, a factory, and a warehouse, there is known a structure in which a plurality of wall panels are erected and sequentially joined (Patent Documents 1, 2 and the like). ). By the way, various materials and articles are transported on a forklift indoors such as in factories and warehouses.When placing the transported goods on the floor, the forks of the forklift are lowered and the transported goods are removed. The entire pallet is placed on the floor. In carrying out such unloading work, there is a case where the conveyed object is placed on the floor while approaching the wall, but at this time, the tip of the lowered fork may hit the wall . Alternatively, the tip of the lowered fork may be lightly brought into contact with the wall to recognize that the fork is closest to the wall, and may be unloaded.

  Here, in order to avoid a problem such as a scratch or deformation caused by the fork directly hitting the wall, the fork is attached to a wall, such as a wall panel, in a lower region of the wall where the fork may be hit when descending. A guard structure is provided to prevent direct contact with the material. As such a guard structure, a high-strength steel plate is placed on the wall to cover the wall, or the lower part of the wall is made of concrete, and a wall made of wall material is built on top of it and a fork hits the concrete. There is something that I did.

  In the guard structure that covers the wall surface with a steel plate as described above, since the steel plate is superimposed on and in contact with the wall material, the impact received by the steel plate is transmitted to the wall material, and the wall material may be dented or deformed together with the steel plate. It happened and was not valid. Also, when the lower part of the wall is made of concrete, the fork does not hit the wall material on the concrete, but when removing the wall by changing the layout, it is necessary to remove the concrete from the floor, which is troublesome The problem arises.

  The present invention has been made in view of the above circumstances, it is possible to reliably prevent deformation and damage of the wall without contact with the fork of the forklift, and to flexibly cope with the removal and relocation of the wall, An object of the present invention is to provide a wall guard structure capable of suppressing deformation and damage of a guard structure member.

  The wall guard structure of the present invention includes a guard member integrally having a base portion fixed to a floor surface and a guard portion facing a wall surface of the wall erected on the floor surface and protecting the wall surface. A cushioning member provided between the base part and the floor surface of the member, and a movable fixing means for fixing the base part to the floor surface so as to be relatively movable in a direction to be at least separated from and brought into contact with the wall surface; And wherein the base portion is fixed to the floor surface by the movable fixing means via the cushioning material in a state where the guard portion is separated from the wall surface by a predetermined distance.

  The phrase "the base portion is fixed so as to be relatively movable with respect to the floor" by the movable fixing means of the present invention means, for example, when the guard member receives a large impact due to the collision of the fork of the forklift with the guard member. That is, the base portion is fixed in a movable state with respect to the floor according to the magnitude of the stress. Further, the guard member of the present invention is, for example, installed in an area where a fork of a forklift is likely to collide and prevents the fork from directly colliding with a wall, and a metal plate such as a steel plate having high strength and rigidity is preferable. Used for

  According to the present invention, the wall is protected by the guard portion of the guard member. For example, when the fork of the forklift hits the guard portion, the fork does not directly hit the wall, and since a predetermined space is provided between the guard portion and the wall, the impact received by the guard portion is not transmitted to the wall. As a result, deformation and damage of the wall are reliably prevented. Further, by making the movable fixing means detachable, the guard member can be removed or relocated, and therefore, it is possible to flexibly cope with the removal or relocation of the wall.

Deformation of the member is suppressed.

  When a large impact is applied to the upper part of the guard in the direction toward the wall surface, the entire guard member receives a stress that tilts toward the wall with the base as a fulcrum. In this case, in the present invention, the cushioning material interposed between the base portion and the floor surface is deformed, whereby the shock received by the guard portion is absorbed, and the deformation or damage of the movable fixing means or the deformation of the guard member is reduced. Can be suppressed. Furthermore, if the guard receives a large impact that cannot be absorbed even by deformation of the cushioning material, the impact is absorbed by the function of the movable fixing means, and the movable fixing means is deformed or damaged, or the guard member is deformed. Is suppressed.

  The present invention includes a mode in which a cushioning material is provided on an inner surface of the guard portion that faces the wall surface. According to this aspect, even if the guard portion is tilted or moved in the direction of the wall surface, it is possible to avoid the possibility that the cushioning material contacts the wall and the guard portion directly contacts the wall and is damaged. .

  Further, the present invention includes a mode in which a cover member is provided between an upper end of the guard portion and the wall surface. According to this aspect, it is possible to prevent a problem that dust or the like enters between the guard portion and the wall surface, or that an object is accidentally dropped between the guard portion and the wall surface.

[2] Wall Guard Structure As shown in FIGS. 1 and 3, a guard structure according to one embodiment is provided on the front side of the partition wall 10A. The guard structure mainly includes a guard member 40, and is provided on the floor surface 1a mainly to protect the wall panel 10 from the fork F of the forklift (see FIG. 3).

  The guard member 40 is formed by bending a metal plate made of a galvanized steel plate or the like having a required strength and rigidity of, for example, about 2.3 to 3.2 mm in a substantially L shape, as shown in FIG. , A base 41 fixed to the floor 1a, and a guard 45 standing upright on the floor 1a. The guard member 40 is provided at a predetermined distance from the wall surface 10a on the floor surface 1a in a place where the partition wall 10A needs to be protected.

  The base portion 41 and the guard portion 45 form a right angle, and are fixed to the floor surface 1a in a state where the base portion 41 protrudes toward the near side of the partition wall 10A. The base portion 41 is fixed with the cushioning material 50 interposed between the base portion 41 and the floor surface 1a. The cushioning material 50 is formed of a material having an appropriate cushioning function in the form of a sheet. Examples of the material include rubber such as butyl rubber, or a laminate of paper, but is not limited thereto.

  The thickness of the cushioning material 50 is, for example, about 10 to 50 mm. The cushioning member 50 may be provided in the entire region between the base portion 41 and the floor surface 1a, or may be divided and arranged at intervals. The base portion 41 is fixed to the floor surface 1a by the movable fixing means 60 with the cushioning material 50 interposed between the base portion 41 and the floor surface 1a. In this fixed state, the guard member 40 is provided in a state where the guard portion 45 is parallel to the wall surface 10a with a predetermined interval (for example, about 50 mm).

  The fixed portions of the base portion 41 to the floor surface 1a by the movable fixing means 60 are set at regular intervals. As shown in FIG. 4, the movable fixing means 60 includes the base 41 itself, a long hole 411 formed in the base 41, a washer 61, and an anchor bolt (screw member) 62.

  The elongated hole 411 is formed in the base portion 41 so as to extend in the direction of separation and contact with the wall surface 10a, that is, in the front-back direction toward the wall surface 10a. The long hole 411 has a width through which the anchor bolt 62 can be inserted, and has a length that is about several times the diameter of the anchor bolt 62. The washer 61 is formed in a rectangular shape and has a size enough to cover the long hole 411, and a circular bolt insertion hole 611 slightly larger than the diameter of the anchor bolt 62 is formed at the center thereof. .

  The washer 61 is overlaid on the upper surface of the base portion 41 so as to cover the long hole 411, the bolt insertion hole 611 is aligned with the center of the long hole 411, and the anchor bolt 62 is passed through the bolt insertion hole 611, the long hole 411, and the cushioning material 50. By screwing the anchor bolt 62 into the floor slab 1, the base portion 41 is fixed to the floor slab 1 together with the washer 61.

  As the washer 61, one having strength and rigidity capable of withstanding the fastening force of the anchor bolt 62 is used. For example, a plate material having the same material as the guard member 40 and an arbitrary thickness is used. In the present embodiment, the washer 61 has a rectangular shape, but the shape of the washer 61 is arbitrary as long as it covers the long hole 411. The cushioning material 50 is provided with a hole through which the anchor bolt 62 is penetrated at the time of construction if possible, and a hole through which the anchor bolt 62 is penetrated if the material is difficult to penetrate.

  In the present embodiment, a cushioning material 70 is provided on a surface of the guard portion 45 of the guard member 40 facing the wall surface 10a, that is, on the inner surface 451 by means such as adhesion. The cushioning member 70 prevents the guard portion 45 from directly contacting the wall surface 10a, and may be provided on almost the entire inner surface 451, or may be partially provided at a necessary portion if the function is fulfilled. It may be. For example, the buffer 70 may be made of the same material as the buffer 50 described above, or may be formed of a different appropriate material.

  In the present embodiment, a cover (cover member) 80 is provided between the upper end of the guard portion 45 of the guard member 40 and the wall surface 10a. The shed 80 is made of, for example, a thin metal plate having elasticity, and as shown in FIG. 3, the inclined portion 82 is inclined downward from the fixed portion 81 along the wall surface 10a toward the near side (the guard portion 45 side). A bent portion 83 is provided at the tip of the inclined portion 82 on the outer surface side of the guard portion 45, and the fixed portion 81 is fixed to the wall panel 10 by rivets 85. The upper portion of the space between the guard portion 45 and the wall surface 10a is covered with the cap 80. Although not shown, a side cover for closing the space is provided on the side of the space covered by the cap 80, that is, on the side opening of the space defined by the cap 80, the guard 45 and the wall surface 10a. Can be

[3] Operation and Effect of the Embodiment According to the guard structure of the present embodiment, the partition wall 10A is protected by the guard portion 45 of the guard member 40. For example, when the fork F of the forklift hits the guard portion 45, the fork F does not directly hit the wall panel 10, and since a predetermined interval is provided between the guard portion 45 and the wall surface 10a, the impact received by the guard portion 45 is reduced. It does not reach the wall panel 10. As a result, deformation and damage of the wall panel 10 are reliably prevented.

  In protecting the wall panel 10 from the fork F of the forklift, the fork F is likely to collide with the wall panel 10 at the time of lowering and unloading. Therefore, the height range of the guard portion 45 is, for example, 100 to 800 mm from the floor surface 1a. Is effective because the height position of the tip of the fork F in the lowered state can be sufficiently covered.

  When a strong impact is received from the fork F of the forklift, the following operation occurs. First, when a large impact in the direction toward the wall surface 10a is applied to the central portion in the height direction of the guard portion 45 or a portion below the center thereof, the entire guard member 40 receives a stress that moves substantially horizontally toward the wall surface 10a. become. In this case, the movable fixing means 60 functions to move the entire guard member 40 together with the base portion 41 horizontally in a direction approaching the wall surface 10a. That is, while the anchor bolt 62 is fixed to the floor surface 1 a and is immobile, the horizontal movement of the base portion 41 is allowed by the long hole 411. As a result, the entire guard member 40 moves in the direction of the wall surface 10a, whereby a strong impact received from the fork F is absorbed. As a result, the deformation or damage of the anchor bolt 62, the problem that the anchor bolt 62 comes off from the floor slab 1, and the deformation or damage of the guard member 40 itself are suppressed.

  When a strong impact is applied to the upper part of the guard portion 45 in the direction toward the wall surface 10a, as shown in FIG. 5, the entire guard member 40 tilts toward the wall surface 10a with the base portion 41 as a fulcrum (indicated by an arrow B). ) It will be stressed. In that case, as shown in FIG. 5, the cushioning material 50 interposed between the base portion 41 and the floor surface 1a is crushed and deformed, whereby the shock received by the guard portion 45 is absorbed. As a result, it is possible to suppress the deformation or damage of the anchor bolt 62, the occurrence of a problem that the anchor bolt 62 comes off from the floor slab 1, and the deformation or damage of the guard member 40 itself. Further, when the guard portion 45 receives a large impact that cannot be absorbed even by the deformation of the cushioning material 50, the movable fixing means 60 functions to absorb the impact. That is, the base portion 41 moves along the elongated hole 411 in accordance with the stress of the received impact, whereby the impact is absorbed.

  Next, each of the wall panels 10 constituting the partition wall 10A of the present embodiment can be removed or relocated by removing or cutting the anchor bolts 4. The guard member 40 is detachable by pulling or cutting the anchor bolt 62. Therefore, when it becomes necessary to remove or relocate the partition wall 10A, the guard member 40 can be similarly removed or relocated. That is, it is possible to flexibly cope with removal or relocation of the partition wall 10A.

  In the present embodiment, since the cushioning member 70 is provided on the inner surface 451 of the guard part 45, the cushioning member 70 comes into contact with the wall panel 10 when the guard part 45 tilts or moves in the direction of the wall surface 10a. . For this reason, the possibility that the guard portion 45 directly contacts the wall panel 10 and is damaged can be avoided.

  Further, in the present embodiment, since the cap 80 is provided between the upper end of the guard portion 45 and the wall surface 10a, dust or the like may enter between the guard portion 45 and the wall surface 10a, or an object may be erroneously removed by the guard portion. The trouble of dropping between the wall 45 and the wall surface 10a can be prevented beforehand. In addition, the above-described side cover prevents dust and the like from entering the space between the guard member 40 and the wall surface 10a from the side.

[4] Other Embodiments and the like In the guard member 40 of the above embodiment, in particular, the guard portion 45 may be made of a textured steel plate such as a keystone plate, a square wave plate, and a corrugated plate.

  The partition wall 10A of the above embodiment uses a wall panel 10 made of a metal sandwich as a wall material. As the wall material, a wooden panel, a heat insulating panel, and a lightweight cellular concrete panel called an ALC (Autoclaved Light-weight Concrete) panel are used. And wall panels such as lightweight cement molded panels, gypsum boards and the like. These wall members can be fixed to the floor surface 1a at an angle or the like in the same manner as the wall panel 10 of the above embodiment, so that they can be removed or relocated, and thus the guard structure of the present invention can be suitably employed.

  INDUSTRIAL APPLICABILITY The present invention can be applied to a partition wall or the like in a warehouse or a factory where a forklift is used.
