Description

[Technical Field]

[0001] The invention disclosed in this application relates to a fence that is installed to surround a road or a site to prevent animals from running off the road or entering the site, and more specifically to a mounting fixture for fixing a mesh material to the frame material of the fence, and a fence that uses the mounting fixture. [Background technology]

[0002] Fences (protective fences) are installed on the roadsides of expressways and other roads to prevent vehicles and cargo from running off the road. Fences are also sometimes installed to surround specific areas, such as facility grounds or parks, to prevent entry to those areas. Most of these types of fences are composed of pillars erected at appropriate intervals, frame members on the top, bottom, left, and right sides supported by the pillars, and mesh material attached within the frame enclosed by the frame members.

[0003] Patent Document 1 discloses a wire mesh locking structure for a fence (corresponding to a fence body) constructed by attaching a wire mesh (corresponding to a mesh material in the case of a furring strip (corresponding to a frame material in the invention disclosed in this application) to a furring strip, in which horizontal rib wires (corresponding to tension wires in the case of a furring strip) inserted into the upper and lower edge ends of the wire mesh to maintain its shape are engaged with locking claw pieces cut into the vertical plates of the furring strip.

[0004] However, with the wire mesh locking structure disclosed in Patent Document 1, when an excessive load is applied to the wire mesh, the horizontal ribs may come off the locking claws, causing the wire mesh to fall off the furring strip. However, if an attempt is made to fix the edge of the wire mesh to the furring strip using fixing hardware such as bolts and nuts instead of fixing hardware, the worker must fasten the fixing hardware to the furring strip while holding the edge of the wire mesh along the furring strip, etc., which makes the work less efficient.

[0005] Therefore, Patent Document 2 proposes a configuration for a protective fence (corresponding to a fence in the same application) that reduces the risk of the net material falling off from a frame (corresponding to the frame in the invention disclosed in this application) and also improves the ease of work when attaching the net material. This configuration involves forming engagement claws that engage with the edge of the net material on an engagement member attached to a frame that holds the net material, and disengagement prevention members that prevent the edge of the net material from disengaging from the engagement claws are arranged on the side facing the engagement member across the net material, and the disengagement prevention members are bolted to the engagement member with the net material sandwiched between them. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Publication No. 63-184864 [Patent Document 2] Japanese Patent Application Laid-Open No. 2016-125300 Summary of the Invention [Problem to be solved by the invention]

[0007] In the invention disclosed in Patent Document 2, the edges of the wire mesh must be locked onto the engaging claws of all engaging members attached to the frame located on the upper side of the protective fence, and then the anti-detachment members must be placed on each engaging member. In this state, bolts must be inserted through the engaging members and the anti-detachment members and fastened with nuts. At this time, one hand must hold the anti-detachment member and nut, while the other hand must hold and turn the bolt, making it difficult to hold down the wire mesh at the same time. Therefore, the invention disclosed in Patent Document 2, like the invention disclosed in Patent Document 1, is susceptible to the risk of the wire mesh falling off the engaging claws of the engaging members before the engaging members and the anti-detachment members are fastened with the bolts. The same problem exists with the frames located on both sides and below the protective fence. It is difficult to attach anti-detachment members while temporarily fastening the edges of the wire mesh to the engaging members.

[0008] Furthermore, in the invention disclosed in Patent Document 2, the work of screwing nuts onto bolts inserted into the engaging members and the separation prevention members must be done from the back side of the wire mesh, which makes the work position difficult. Since work on expressway overpasses can often only be done from the road side, there is a risk of an accident in which the nuts are dropped to the outside of the road (under the overpass).

[0009] The invention disclosed in this application was conceived to improve the workability of the mesh material installation work described above, and aims to provide a user-friendly mesh material installation tool that makes mesh material installation work easier and safer than before, and a fence body using this installation tool. [Means for solving the problem]

[0010] The net material mounting fixture of the invention disclosed in this application is a mounting fixture for mounting the edge of the net material to the frame material in a fence structure comprising a plurality of frame materials supported by suitable pillars and a net material stretched within a frame surrounded by the frame materials, and comprises a flat mounting base plate attached to the inside of the frame material and arranged parallel to the net material, a net material locking member formed separately from the mounting base plate and attached to the mounting base plate, and a fastening member for overlapping and joining the mounting base plate and the net material locking member, and the mounting base plate has an assembly hole having a long axis parallel to the frame material and arranged close to the frame material, and a fastening member insertion hole arranged away from the assembly hole towards the inside of the frame The mesh material locking member has an insertion piece that can be inserted into the assembly hole of the mounting base, a mesh material receiving portion that is bent forward from one end edge of the insertion piece and continues, and a locking claw piece that is bent and extends from the front end edge of the mesh material receiving portion in the opposite direction to the insertion piece, and a fastening member mounting hole is formed in the insertion piece, the insertion piece of the mesh material locking member is inserted into the assembly hole of the mounting base from the front side and is placed on the back side of the mounting base, and the mounting base and the insertion piece are joined together via the fastening member inserted into the fastening member insertion hole and the fastening member mounting hole with the tip of the locking claw piece being held on the front side of the mounting base with its tip facing the frame material.

[0011] With this type of net mounting fixture, the net locking member with the locking tab is formed separately from the mounting base, and by inserting the insertion tab into an assembly hole formed in the mounting base, the net tension wire can be easily locked onto the locking tab. Since the net locking member and fastening members are assembled to the mounting base and the net can be locked even when the fastening members are in a temporary fastened state, it is possible to perform the procedure of first locking the net tension wire to multiple mounting fixtures and then fully tightening the fastening members all at once.

[0012] Furthermore, the net mounting fixture of the present invention employs an additional configuration in which the net material receiving portion of the net material locking member is formed wider than the longitudinal dimension of the assembly hole, the fastening member insertion hole formed in the mounting base is formed as an elongated hole extending in a direction perpendicular to the longitudinal axis of the assembly hole, the insertion piece of the net material locking member is inserted into the assembly hole of the mounting base from the front side, and with the net material receiving portion abutting against the assembly hole, the net material locking member is held so as to be swingable back and forth relative to the mounting base about the abutment point with the assembly hole. With this configuration, even when the fastening member is inserted into the mounting base and loosely fastened temporarily, the net material locking member can swing within a certain range, making the net material locking operation even easier.

[0013] In the above-described configuration, the fastening members may be bolts and nuts, and the fastening member mounting holes formed in the insert pieces of the net-holding members may be bolt insertion holes, so that the mounting base and the insert pieces are joined by the bolts and nuts. With this configuration, the direction in which the bolts are inserted can be selected according to the conditions at the construction site.

[0014] Alternatively, the fastening member may be a bolt, the fastening member mounting hole formed in the insertion piece of the net material locking member may be an internally threaded hole, and the bolt may be fastened to the internally threaded hole from the front side of the mounting base. With this configuration, the net material can be locked and the fastening member can be fully tightened simply by working from the front side of the net material, further improving workability and preventing accidents such as dropping nuts behind the net material.

[0015] Furthermore, the fence body of the invention disclosed in this application is characterized in that the mounting base of the mesh material mounting fixture configured as described above is attached to the inside of the frame of the frame material that holds the edge of the mesh material, the mesh material locking member and the fastening member are assembled to the mounting base, and the shape-retaining tension wire arranged at the edge of the mesh material is locked by the locking claws of the mesh material locking member from the front side of the mounting base and held in the mesh material receiving portion, and the mounting base and the mesh material locking member are connected via the fastening member. [Effects of the Invention]

[0016] In the net mounting fixture constructed as described above, the net locking members with locking claws are formed separately from the mounting base. Therefore, the insertion pieces of the net locking members can be inserted into the mounting holes of the mounting base and the fastening members loosely fastened. The net tension wires can be easily locked to the locking claws of the net locking members. This increases the flexibility of manual operation, allowing the net tension wires to be quickly locked to multiple mounting fixtures, while also reducing the risk of the net falling off the mounting fixtures during the operation. Furthermore, since the net locking members and fastening members can be pre-assembled to the mounting base, there is no risk of the net locking members or fastening members being accidentally dropped during on-site work. After the net tension wires are locked to multiple mounting fixtures, the fastening members of each mounting fixture can be fully tightened together to firmly secure the net to the frame. This significantly improves the ease of attaching nets to mounting fixtures attached to a frame.

[0017] Furthermore, if the net material locking member is configured to be able to swing back and forth while attached to the mounting base, the work of temporarily fastening the net material becomes even easier. Also, the length of the locking claw can be extended by the amount that the net material locking member can swing, thereby increasing the holding force of the net material.

[0019] Hereinafter, embodiments of the invention disclosed in this application will be described with reference to the drawings. FIG. 1 shows a schematic configuration example of a fence 1 to which a mounting device according to the present invention is applied. This type of fence 1 basically comprises a plurality of pillars 2 erected at appropriate intervals along the boundary of the area to be partitioned, a plurality of frame members 3 supported by the pillars 2, and a mesh member 4 stretched within the frame surrounded by the frame members 3. However, in this invention, the type and shape of the area to be partitioned are not particularly limited. Furthermore, the type, structure, material, etc. of the pillars 2 and the foundation structure supporting the pillars 2 are not particularly limited.

[0020] The frame members 3 extend horizontally and vertically (and diagonally in some cases) according to the length and height of the area to be partitioned. Fig. 1 shows upper and lower frame members 31 and 32 extending horizontally and facing each other, and a vertical frame member 33 connecting them at one side end, but the present invention is not particularly limited to the arrangement or connection of the frame members 3. In addition, although circular pipe members are used for the frame members 3 in the illustrated embodiment, square timbers or shaped members with an appropriate cross section can also be used instead.

[0021] The mesh material 4 is cut to a size that fits within the dimensions of the frame enclosed by the frame material 3 and stretched within the frame. Tendons 41, made of thick steel wire or the like, are attached to the edges of the mesh material 4 to maintain its shape. In the illustrated embodiment, diamond-shaped wire mesh is used as the mesh material 4, but other materials that can be used include crimped wire mesh, which is made by corrugating metal wire and weaving it into a lattice pattern; tortoiseshell wire mesh, which is made by weaving metal wire into a hexagonal pattern; lattice panels, which are made by joining metal wires together without weaving them; expanded metal, which is made by cutting a thin metal plate with staggered cuts and expanding it; and punched metal, which is made by punching a thin metal plate with numerous holes at equal intervals. Furthermore, the mesh material 4 is not limited to being made of metal, but may also be made of synthetic resin, wood, bamboo, or other natural materials.

[0022] The mounting fixture 5 according to the present invention is a component that is connected to the frame material 3 at the circled portion B of the fence body 1 as shown in the example, and is configured to lock onto tension wires 41 arranged at the edge of the mesh material 4. Figures 2 to 8 show the configuration of the mounting fixture 5 according to one embodiment of the present invention.

[0023] The mounting fixture 5 according to the present invention basically comprises a flat mounting base 6 attached to the inside of the frame member 3 and arranged parallel to the net material 4, a net material locking member 7 formed separately from the mounting base 6 and attached to the mounting base 6, and a fastening member 8 that overlaps and connects the mounting base 6 and the net material locking member 7. The detailed configuration of each of these components will be described below. When describing the relative positional relationships and operational directions of parts and members below, the front side, from the perspective of the fence body 1 viewed from the direction perpendicular to its surface (front view in Figure 1), is defined as the front side, where the net material 4 is to be attached, and the opposite side across the net material 4 is defined as the back side, and the up-down direction (height direction), left-right direction (width direction), and front-to-back direction (depth direction) are specified based on these.

[0024] The mounting substrate 6 is a plate piece with a generally rectangular or U-shaped surface and flat front and back, with at least one side formed in a straight line. The mounting substrate 6 is attached to the inside of the frame member 3 with one straight side (the upper side in the form of Figure 2) parallel to the axis of the frame member 3 (the upper frame member 31 in the form of Figure 2), and is positioned so as to be parallel to the stretched surface of the mesh material 4. The mounting substrate 6 may be attached to the frame member 3 by welding, or by using appropriate mounting hardware, screws, etc. When attaching the mesh material 4, multiple mounting substrates 6 are attached in advance at approximately equal intervals to the frame member 3 to which the mesh material 4 will be attached.

[0025] Two through holes are formed in the mounting substrate 6. The first through hole is an assembly hole 61 located closer to the frame material 3, and is formed in the shape of an elongated rectangle or oval with a long axis parallel to the frame material 3. The second through hole is a fastening member insertion hole 62 located away from the assembly hole 61 towards the inside of the frame, and is formed in the shape of an oval extending in a direction perpendicular to the long axis of the assembly hole 61. Although not shown, the fastening member insertion hole 62 may open on the opposite side of the frame material 3 in the mounting substrate 6 (the lower side in the illustrated embodiment). The assembly hole 61 and the fastening member insertion hole 62 are both located in the center of the width direction of the mounting substrate 6 so as to be symmetrical when the mounting substrate 6 is viewed from the front.

[0026] The net material locking member 7 is a member formed by bending a single plate piece into a generally Z-shape (crank shape) in side view. The net material locking member 7 has an insertion piece 71 that is generally rectangular or generally U-shaped in front view, a net material receiving portion 73 that bends forward from one end edge of the insertion piece 71 and continues, and a locking claw piece 74 that is bent in an inverted U-shape in front view and extends from the front end edge of the net material receiving portion 73 and bent in the opposite direction to the insertion piece 71. The insertion piece 71 is formed with a width that allows it to be inserted into the assembly hole 61 of the mounting board 6. A fastening member mounting hole 72 is formed near the tip of the insertion piece 71, into which a bolt 81 of the fastening member 8, described later, is inserted. The fastening member mounting hole 72 in the illustrated embodiment is a circular through-hole.

[0027] The mesh material receiving portion 73 is bent forward at an angle of approximately 90 degrees and continues from the insertion piece 71. The mesh material receiving portion 73 is formed so that its both side edges protrude to the left and right and its width is larger than the long axis dimension of the assembly hole 61.

[0028] The locking claw pieces 74 are bent at an angle slightly greater than 90 degrees (approximately 96 degrees in the illustrated embodiment) and are continuous with the net material receiving portion 73. In the illustrated embodiment, the locking claw pieces 74 are formed so that their width is smaller than the width of the net material receiving portion 73, but the locking claw pieces 74 may be formed so that they are approximately the same width as the net material receiving portion 73 or wider.

[0029] The fastening member 8 is configured by, for example, a bolt 81 and a nut 82. In the illustrated embodiment, a flanged hexagonal bolt and a hexagonal nut are used.

[0030] As shown in Figures 5 and 6, the mounting base 6 and net material locking member 7 are assembled by inserting the insertion piece 71 of the net material locking member 7 into the assembly hole 61 of the mounting base 6 from the front side. The net material receiving portion 73 of the net material locking member 7 is formed so that it cannot pass through the assembly hole 61, so the net material receiving portion 73 and the locking claw piece 74 are held on the front side of the mounting base 6 and are held in a state where they can swing back and forth around the point of contact with the assembly hole 61 as a fulcrum. The depth of the net material receiving portion 73 is formed so that when the net material locking member 7 is assembled to the mounting base 6, the part that protrudes forward of the mounting base 6 is larger than the diameter of the tension wire 41 of the net material 4.

[0031] When the locking claw pieces 74 are raised toward the frame material 3, the insertion pieces 71 of the net locking member 7 overlap the back side of the mounting base 6, and the fastening member insertion holes 62 formed in the mounting base 6 and the fastening member attachment holes 72 formed in the insertion pieces 71 align. When a bolt 81 is inserted into the fastening member insertion holes 62 and the fastening member attachment holes 72 and fastened with a nut 82, the state shown in Figures 7 and 8 is obtained. In the illustrated embodiment, the bolt 81 is inserted from the back side and the nut 82 is fastened from the front side, but the direction in which the bolt 81 is inserted can be selected to be either front or back depending on the conditions of the installation location, etc.

[0032] When fastening the net material 4 to this mounting fixture 5, the tension wires 41 of the net material 4 can be easily fastened to the tension hooks 74 from the front side by tilting the locking claws 74 forward without fastening the fastening members 8, as shown in Figure 6. Furthermore, in this mounting fixture 5, the fastening member insertion holes 62 formed in the mounting base 6 are elongated holes extending in a direction perpendicular to the long axis of the assembly hole 61. Therefore, even when the fastening members 8 are inserted into the mounting base 6 and the net material locking members 7 and loosely fastened, the net material locking members 7 can be swung within a certain range. Therefore, if the net material locking members 7 and fastening members 8 are previously assembled to multiple mounting bases 6 attached to the frame material 3 and the fastening members 8 are temporarily fastened, the mounting work can be performed in the following procedure: the tension wires 41 of the net material 4 are fastened to the multiple mounting fixtures 5, and then the fastening members 8 are fully fastened together.

[0033] This procedure significantly improves workability compared to the conventional procedure of fastening a fastening member 8 to each fixture 5 to which the tension wires 41 of the net material 4 are fastened. Furthermore, the length of the locking tabs 74 can be slightly extended to allow for swinging of the net material fastening member 7, making it easier to prevent the temporarily fastened net material 4 from falling off. Furthermore, when fastening the upper edge of the net material 4 to the fixture 5 attached to the upper frame member 31, the weight of the fastening member 8 inserted into the insertion piece 71 and temporarily fastened causes the net material fastening member 7 to rotate backward, and the locking tabs 74 naturally point upward, making it even more difficult for the tension wires 41 temporarily fastened to the net material fastening member 7 to fall off. Finally, when the fastening member 8 is fully fastened, the tension wires 41 of the net material 4 are firmly held on the net material receiving portion 73, as shown in Figure 7.

[0034] FIG. 9 shows a modified version of the fastening member 8 in the mounting fixture 5. The fastening member 8 in the illustrated embodiment is composed solely of a bolt 81 without a nut. The illustrated bolt 81 is a hexagonal socket head bolt 81 with a knurled head, but the shape of the head is not particularly limited. Meanwhile, a fastening member mounting hole 72 formed in the insert piece 71 of the net locking member 7 is internally threaded, and the bolt 81 is fastened to the internally threaded hole from the front side of the mounting base 6. In the illustrated embodiment, the internal thread is formed by thickening the periphery of the fastening member mounting hole 72, but thickening may not be necessary if the insert piece 71 is sufficiently thick. Furthermore, if the insert piece 71 is thin, a thin nut that can pass through the mounting hole 61 of the mounting base 6 may be welded to form the internally threaded hole. Adopting such a configuration eliminates the need to set the fastening member 8 on the back side of the net 4, and the work can be done only from the front side of the net 4, further improving workability. In addition, accidents such as dropping nuts 82 onto the rear surface of the net material 4 can be prevented.

[0035] If a female screw hole such as the one shown in the example is used, the direction in which the bolt 81 is inserted is limited, which may reduce workability depending on the conditions of the construction site. In contrast, the bolt 81 and nut 82 described above have the advantage that the direction in which the bolt 81 is inserted is not limited, allowing work to be done according to the construction site.

[0036] By using the fixtures 5 configured as described above, it is no longer necessary to manually hold down the mesh material 4 temporarily fastened to each fixture 5 to prevent it from falling off, or to fasten the fastening members 8 to each temporarily fastened fixture 5, which increases the worker's freedom of use and allows for efficient completion of the series of operations from temporarily fastening the mesh material 4 to fully tightening the fastening members 8. Thus, the workability of attaching the mesh material 4 to the frame material 3 is greatly improved.

[0037] The technical scope of the invention disclosed in this application should not be construed as being limited by the exemplified embodiments, but should be construed conceptually based on the claims. The names of elements used in the claims and specification are for convenience in making the invention easier to understand specifically, and the names do not unnecessarily limit the concepts or properties of the elements. When implementing the invention disclosed in this application, the detailed shape, dimensions, materials, quantities, combinations with other elements, relative positional relationships, etc. of elements not specifically specified in the claims may be modified as appropriate within the scope that provides substantially the same operational effects as those of the exemplified embodiments. [Industrial Applicability]

[0038] The invention disclosed in this application can be widely used as a technology for attaching mesh material to frame materials for protective fences and various other fence structures that are installed along the boundaries of specific areas such as roads, sites, parks, etc., for the purpose of enclosing or dividing up the areas.
