Description

[Technical Field]

[0001] The present invention relates to a hexagonal pattern surface lattice member, a method for manufacturing a hexagonal pattern surface lattice member, and a three-dimensional structure. [Background technology]

[0002] Tortoiseshell-patterned surface lattice members are sometimes used for floors, walls, etc. of buildings. Tortoiseshell-patterned surface lattice members are formed into a mesh-like structure by stretching an aluminum alloy extrusion with staggered slits in a direction perpendicular to the direction in which the slits extend (see, for example, Patent Document 1, etc.). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-311045 Summary of the Invention [Problem to be solved by the invention]

[0004] In Patent Document 1, both ends of the extruded profile in the stretching direction are fixed to a frame. With this configuration, when the extruded profile is stretched, force is not easily applied to the ends in the stretching direction, and the force is concentrated in the center in the stretching direction. As a result, the slits in the center in the stretching direction are stretched more than the slits at the ends, which can result in a distorted shape of the overall mesh structure.

[0005] The present invention has been made in view of the above, and aims to provide a hexagonal pattern surface lattice member having a uniform mesh structure, a method for manufacturing the hexagonal pattern surface lattice member, and a three-dimensional structure. [Means for solving the problem]

[0006] A tortoiseshell pattern surface lattice member according to one embodiment of the present invention comprises a base portion that extends in a first direction in a wave-like folded state, and is connected in multiple ways in a second direction perpendicular to the first direction with the folded portions facing each other in the second direction to form a mesh-like structure; and end edge portions that are arranged on both sides of the multiple base portions in the second direction, extend linearly along the first direction, and are connected to the multiple folded portions of the base, and the end edge portions have cut portions that are cut in the first direction in the linear portions between the multiple connected portions with the folded portions that are adjacent in the first direction.

[0007] According to this configuration, when the end edges are pulled apart in the second direction during the manufacturing process of the tortoiseshell pattern surface grating member, the linear portions of the end edges are separated by the cutting sections, allowing the end edges to shrink in the first direction as the base shrinks in the first direction. This results in a uniform mesh between both sides in the stretching direction and the center. This makes it possible to provide a tortoiseshell pattern surface grating member with a uniform mesh structure.

[0008] In a preferred embodiment of the above-mentioned hexagonal pattern surface grating member, the cut portions are provided on the linear portions of the edge portions that are arranged at least on both ends in the first direction.

[0009] According to this configuration, at least both ends of the edge portion in the first direction can be shrunk in the first direction.

[0010] In a preferred embodiment of the hexagonal pattern surface grid member, the cut portions are provided on each of the linear portions arranged over the entire edge portion in the first direction.

[0011] This configuration allows the end portion to shrink uniformly over the entire length in the first direction.

[0012] In a preferred embodiment of the above-mentioned hexagonal pattern surface grid member, the edge portions are arranged so as to protrude from the connecting portions on both sides in a third direction perpendicular to the first direction and the second direction.

[0013] According to this configuration, when the end edge portions are pulled apart in the second direction during the process of manufacturing the tortoiseshell pattern surface lattice member, they can be pulled while other members are engaged with the portions protruding on both sides in the third direction.

[0014] A method for manufacturing a tortoiseshell pattern surface lattice member according to one embodiment of the present invention includes: bases that extend linearly along a first direction and are arranged in a plurality of positions in a second direction perpendicular to the first direction; end edges that are arranged on both sides of the plurality of bases in the second direction and extend linearly along the first direction; and connecting portions that connect the bases to each other and to the end edges so that slits are formed in a staggered pattern between the bases and between the bases and the end edges, the end edges having cut portions that are separated at intervals in the first direction in the linear portions between the connecting portions that are adjacent in the first direction; the method includes the steps of: attaching a frame body to each of the end edges in a state that the frame body is movable in the first direction; and deforming the bases by pulling the frame bodies apart in the second direction so that the slits widen in the second direction at the connecting portions.

[0015] According to this configuration, when the end edges are pulled apart in the second direction during the process of manufacturing the tortoiseshell pattern surface grating member, the linear portions of the end edges are separated by the cutting sections, so that the end edges shrink in the first direction as the base shrinks in the first direction. As a result, the slits expand evenly between both sides in the stretching direction and the center, resulting in a uniform mesh. This makes it possible to manufacture a tortoiseshell pattern surface grating member with a uniform mesh structure.

[0016] In a preferred embodiment of the method for manufacturing the tortoiseshell patterned surface lattice member, the end edge portions are arranged to protrude on both sides of the connecting portion in a third direction perpendicular to the first direction and the second direction, and the frame body is attached so as to engage with protruding portions of the end edge portions that protrude from the connecting portion on both sides in the third direction.

[0017] According to this configuration, the base can be deformed by pulling the frame body while the frame body is engaged with the portions protruding on both sides in the third direction.

[0018] In a three-dimensional structure according to one aspect of the present invention, the above-described hexagonal pattern surface lattice member is provided on at least one of the floor and wall.

[0019] According to this configuration, a tortoiseshell pattern surface lattice member having a uniform mesh structure is provided on at least one of the floor and wall portions, making it possible to provide a three-dimensional structure with high quality in terms of appearance and strength. [Effects of the Invention]

[0020] According to the present invention, it is possible to provide a hexagonal pattern surface lattice member having a uniform mesh structure, a method for manufacturing the hexagonal pattern surface lattice member, and a three-dimensional structure. [Brief explanation of the drawings]

[0022] Hereinafter, embodiments of the tortoiseshell pattern surface grating member according to the present invention will be described with reference to the drawings. However, the present invention is not limited to these embodiments. Furthermore, the components in the following embodiments include those that are easily replaceable by those skilled in the art, or those that are substantially identical.

[0023] Fig. 1 is a plan view showing an example of a hexagonal pattern surface lattice member 100 according to this embodiment. Fig. 2 is a plan view showing an example of a state in which a frame body 40 is attached to the hexagonal pattern surface lattice member 100. Fig. 3 is an enlarged view showing a main part of the hexagonal pattern surface lattice member 100. Fig. 4 is an enlarged view showing a main part of the hexagonal pattern surface lattice member 100 in a state in which the frame body 40 is attached.

[0024] As shown in FIGS. 1 to 4, the hexagonal pattern surface grid member 100 includes a base portion 10, edge portions 20, and connecting portions 30.

[0025] The base 10 is formed using a material such as an aluminum alloy. The base 10 extends in a first direction D1 while being folded back in a wave-like manner. The base 10 has a plurality of folded portions 11. The folded portions 11 of the base 10 are connected in the second direction D2 via first connecting portions 31, which will be described later, with each folded portion 11 facing each other in the second direction D2 perpendicular to the first direction D1. The base 10 is formed in a mesh shape with openings 14 while connected in the second direction D2. In the tortoiseshell pattern surface lattice member 100 according to this embodiment, the base 10 is formed in a mesh shape so that the size of the openings 14 is uniform in both the first direction D1 and the second direction D2.

[0026] The end portions 20 are formed using a material such as an aluminum alloy. The end portions 20 are arranged on both sides of the base 10 in the second direction D2. The end portions 20 extend linearly along the first direction D1. The end portions 20 are connected to the multiple folded portions 11 of the base 10 via second connecting portions 32, which will be described later.

[0027] The end side portion 20 has cut portions 21. The cut portions 21 are provided in the linear portions 22 of the end side portion 20 between adjacent second connecting portions 32, 32. The cut portions 21 are formed so as to extend the linear portions 22 to both ends in the first direction D1. The cut portions 21 provide the linear portions 22 at equal intervals in the first direction D1.

[0028] For example, as in this embodiment, the cut portions 21 can be configured to be provided on each of the linear portions 22 arranged over the entire length of the edge portion 20 in the first direction D1. For example, the cut portions 21 may be configured to be provided on at least the linear portions 22 at both ends of the edge portion 20 in the first direction D1, and the cut portions 21 may not be provided on the linear portions 22 other than those at both ends of the edge portion 20 in the first direction D1. However, from the viewpoint of maintaining a uniform mesh structure, it is preferable to provide the cut portions 21 at equal intervals between two adjacent second connecting portions 32.

[0029] The connecting portion 30 has a first connecting portion 31 and a second connecting portion 32. The first connecting portion 31 connects the folded portions 11 of the base portion 10 to each other. The second connecting portion 32 connects the folded portions 11 of the base portion 10 to the end portion 20.

[0030] As shown in Fig. 2, a frame body 40 is attached to the end edge portion 20. Fig. 5 is a diagram showing a cross-sectional configuration along line AA in Fig. 4. Fig. 5 shows the cross-sectional configuration of the base portion 10, end edge portion 20, connecting portion 30, and frame body 40 in a state in which the frame body 40 is attached. As shown in Fig. 5, the end edge portion 20 is arranged so as to protrude in one direction (e.g., upward in Fig. 5) and the other direction (e.g., downward in Fig. 5) in the third direction D3 relative to the second connecting portion 32.

[0031] In FIG. 5, the frame body 40 has a first locking portion 41 and a second locking portion 42, each of which has a C-shape in cross section. The first locking portion 41 is locked to a portion of the end side portion 20 that protrudes from the second connecting portion 32 in one direction in the third direction D3 (e.g., upward in FIG. 5). The second locking portion 42 is locked to a portion of the end side portion 20 that protrudes from the second connecting portion 32 in the other direction in the third direction D3 (e.g., downward in FIG. 5). The frame body 40 is attached to the end side portion 20 so that it slides from an end in the first direction D1, for example. The frame body 40 is movable in the first direction D1 with the first locking portion 41 and the second locking portion 42 locked to the end side portion 20.

[0032] Next, a method for manufacturing the hexagonal pattern surface lattice member 100 configured as described above will be described. Figures 6 to 8 are diagrams showing an example of the manufacturing process for the hexagonal pattern surface lattice member 100. First, as shown in Figure 6, an extruded shape member 150 that serves as the base for the hexagonal pattern surface lattice member 100 is formed. The hexagonal pattern surface lattice member 100 is manufactured by deforming the extruded shape member 150 as described below.

[0033] The extruded profile 150 includes a base 15, end edge portions 25, and connecting portions 35. The bases 15 extend linearly along a first direction D1, and a plurality of the bases 15 are arranged in a second direction D2 perpendicular to the first direction D1. The end edge portions 25 are arranged on both sides of the plurality of bases 15 in the second direction D2 and extend linearly along the first direction D1. The connecting portions 35 connect the bases 15 to each other and between the bases 15 and the end edge portions 25 so that slits S are formed in a staggered pattern between the bases 15 and between the bases 15 and the end edge portions 25.

[0034] Additionally, the edge portions 25 have cut portions 26 that are separated at intervals in the first direction D1 in linear portions 27 between adjacent connecting portions 35 in the first direction D1. The interval L2 in the first direction D1 of the cut portions 26 is larger than the interval L1 in the first direction D1 of the cut portions 21 of the edge portions 20 in the above-described tortoiseshell pattern surface lattice member 100. The edge portions 25 are arranged so as to protrude from the connecting portions 35 on both sides in a third direction D3 that is perpendicular to the first direction D1 and the second direction D2.

[0035] After forming the extruded profile 150, as shown in Fig. 7, a frame body 40 is attached to each end edge portion 25 at both ends in the second direction D2. The configuration of the frame body 40 is the same as that described above. The frame body 40 is attached by sliding it from the end of the end edge portion 25 in the first direction D1 so that the first locking portion 41 and the second locking portion 42 are locked to the portion of the end edge portion 25 that protrudes in the third direction D3 relative to the connecting portion 35.

[0036] After the frame bodies 40 are attached, as shown in Fig. 8, the frame bodies 40 are pulled apart in the second direction D2, which causes the base 15 to deform so that the slits S widen in the second direction D2. Note that Fig. 8 omits illustration of a portion of the frame body 40, and shows the edge portions 25 of the omitted portion of the frame body 40 so that they are visible for the sake of explanation. The base 15 deforms into a wavy shape, folded back in the second direction D2 at each connecting portion 35. By deforming in a folded manner, the base 15 contracts in the first direction D1.

[0037] This deformation of the base 15 also causes a contracting force to act on the end edge portion 25 in the first direction D1 via the connecting portion 35. In this embodiment, the end edge portion 25 is movable in the first direction D1 relative to the frame 40, and the cut portion 26 is provided on the end edge portion 25. Therefore, when a force in the first direction D1 acts on the end edge portion 25, the end edge portion 25 can move in the first direction D1 at each portion connected to the connecting portion 35. As a result, the end edge portion 25 as a whole contracts in the first direction D1 in response to the deformation of the base 15. Furthermore, because the cut portion 26 is provided to leave a gap L2 (see FIG. 6) in the first direction D1, the end edge portion 25 can smoothly deform to reduce the gap. The gap L3 shown in FIG. 8 is smaller than the gap L2 before deformation of the extruded profile 150 in FIG. 6, for example.

[0038] As the edge portions 25 contract in the first direction D1, the bases 15 located at both ends in the second direction D2 also deform to the same extent as the base 15 located in the center of the second direction D2. Therefore, when the frame 40 is pulled in the second direction D2, the bases 15 deform uniformly throughout the entire second direction D2. As a result, as shown in FIGS. 1 to 4, it is possible to manufacture a hexagonal pattern surface lattice member 100 in which the bases 10 are formed in a mesh pattern so that the size of the openings 14 is uniform in both the first direction D1 and the second direction D2. The bases 15, edge portions 25, and connecting portions 35 of the extruded profile 150 become the bases 10, edge portions 20, and connecting portions 30 of the hexagonal pattern surface lattice member 100, respectively. Furthermore, the cut portions 26 formed on the edge portions 25 of the extruded profile 150 have a spacing in the first direction D1 that is even smaller than the spacing L3, forming cut portions 21 (spacing L1: see Figure 3) on the edge portions 20 of the hexagonal pattern surface lattice member 100.

[0039] FIG. 9 is a diagram showing a work scaffolding 210 for a bridge 200, which is an example of a three-dimensional structure according to this embodiment. As shown in FIG. 9, the work scaffolding 210 is provided at the bottom of the bridge 200 and is used as a scaffolding for workers inspecting the bridge 200 to perform inspection work, pass over, etc. The bridge 200 includes the work scaffolding 210 and a girder 220. The work scaffolding 210 is a bottom panel that is fixed to a lower flange 204 of the bridge 200 with stud bolts 240 and nuts 242, and protects the bottom of the bridge 200. The work scaffolding 210 is, for example, in the shape of a flat plate and is placed along the bottom of the bridge 200.

[0040] By covering the underside of the bridge 200 in this way, the work scaffolding 210 protects the bridge 200 from the corrosive environment. The work scaffolding 210 also serves as a scaffolding for workers to carry out inspection work, etc. of the bridge 200. For this reason, the work scaffolding 210 is placed at intervals that allow workers to work.

[0041] The work scaffolding 210 includes a bridge protection plate 211 and a mesh member 212. The work scaffolding 210 has a layered structure in which the bridge protection plate 211 and the mesh member 212 are stacked one on top of the other. The mesh member 212 is placed on the lower layer of the bridge protection plate 211. The mesh member 212 is a planar member formed by a lattice, and the front and back surfaces of the surface are connected by gaps. For example, the above-mentioned tortoiseshell pattern surface lattice member 100 can be used as the mesh member 212. In this way, the tortoiseshell pattern surface lattice member 100 having a uniform mesh structure is provided, so that the work scaffolding 210 can be provided with high quality in terms of appearance and strength.

[0042] As described above, the tortoiseshell pattern surface lattice member 100 of this embodiment comprises bases 10 that extend in a wavy folded state in the first direction D1 and are connected in multiple ways in the second direction D2, with the folded portions 11 facing each other in the second direction D2 perpendicular to the first direction D1, to form a mesh-like structure; and end portions 20 that are arranged on both sides of the multiple bases 10 in the second direction D2, extend linearly along the first direction D1, and are connected to the multiple folded portions 11 of the bases 10, and the end portions 20 have cut portions 21 that are cut in the first direction D1 in linear portions 22 between adjacent connecting portions in the first direction D1 among the multiple connecting portions with the folded portions 11.

[0043] According to this configuration, when the end portions 20 are pulled apart in the second direction D2 during the process of manufacturing the tortoiseshell pattern surface lattice member 100, the linear portions 22 of the end portions 20 are separated by the cutting portions 21, so that the end portions 20 can contract in the first direction D1 as the base 10 contracts in the first direction D1. As a result, the mesh is formed uniformly between both sides in the stretching direction and the center. This makes it possible to provide a tortoiseshell pattern surface lattice member 100 with a uniform mesh structure.

[0044] In a preferred embodiment of the hexagonal pattern surface grid member 100, the cut portions 21 are provided in the linear portions 22 of the edge portions 20 that are arranged at least on both ends in the first direction D1.

[0045] According to this configuration, at least both ends of the edge portion 20 in the first direction D1 can be shrunk in the first direction D1.

[0046] In a preferred embodiment of the hexagonal pattern surface grid member 100, the cut portions 21 are provided on each of the linear portions 22 arranged over the entire edge portion 20 in the first direction D1.

[0047] This configuration allows the end portion 20 to shrink uniformly over the entire length in the first direction D1.

[0048] In a preferred embodiment of the hexagonal pattern surface grid member 100, the edge portions 20 are arranged to protrude from the second connecting portion 32 on both sides in a third direction D3 perpendicular to the first direction D1 and the second direction D2.

[0049] According to this configuration, when the end edge portions 20 are pulled apart in the second direction D2 during the process of manufacturing the tortoiseshell pattern surface lattice member 100, they can be pulled while other members are engaged with the portions protruding on both sides in the third direction D3.

[0050] Furthermore, the manufacturing method of the hexagonal pattern surface grid member 100 according to this embodiment includes a method of manufacturing a plurality of base portions 15 that extend linearly along a first direction D1 and are arranged in a second direction D2 that is perpendicular to the first direction D1, end portions 25 that are arranged on both sides of the plurality of base portions 15 in the second direction D2 and extend linearly along the first direction D1, and connecting portions that connect the base portions 15 to each other and the base portions 15 to the end portions 25 so that slits are formed between the base portions 15 and between the bases 15 and the end portions 25 in a staggered pattern. The method includes a step of attaching a frame body 40 to each end edge portion 25 of an extruded profile 150 having connecting portions 35 and cut portions separated at intervals in the first direction D1 in the linear portion between adjacent connecting portions 35 in the first direction D1 of the end edge portions 25, in a state where the frame body 40 is movable in the first direction D1; and a step of deforming the base 15 by pulling the frame bodies 40 apart in the second direction D2 so that the slits of the connecting portions 35 expand in the second direction D2.

[0051] With this configuration, when the end edges 25 are pulled apart in the second direction D2 during the process of manufacturing the tortoiseshell pattern surface lattice member 100, the linear portions of the end edges 25 are separated by the cutting portions, so that the end edges 25 contract in the first direction D1 as the base 15 contracts in the first direction D1. As a result, the slits expand evenly between both sides in the stretching direction and the center, resulting in a uniform mesh. This makes it possible to manufacture a tortoiseshell pattern surface lattice member 100 with a uniform mesh structure.

[0052] In a preferred embodiment of the method for manufacturing the tortoiseshell pattern surface lattice member 100, the edge portions 25 are arranged so as to protrude on both sides of the connecting portion 35 in a third direction D3 that is perpendicular to the first direction D1 and the second direction D2, and the frame body 40 is attached so as to engage with the protruding portions of the edge portions 25 that protrude from the connecting portion 35 on both sides of the third direction D3.

[0053] According to this configuration, the base 15 can be deformed by pulling the frame body 40 while the frame body 40 is engaged with the portions protruding on both sides in the third direction D3.

[0054] The work scaffolding 210, which is a three-dimensional structure according to this embodiment, has the above-mentioned hexagonal pattern surface lattice member 100 provided on at least one of the floor and wall portions.

[0055] According to this configuration, a hexagonal pattern surface lattice member 100 having a uniform mesh structure is provided, making it possible to provide a work scaffolding 210 with high quality in terms of appearance and strength.

[0056] The technical scope of the present invention is not limited to the above-described embodiments, and appropriate modifications can be made without departing from the spirit of the present invention. For example, in the above-described embodiments, the tortoiseshell pattern surface lattice member 100 is applied to the floor of the work scaffolding 210, but it may also be applied to the wall. Furthermore, examples of three-dimensional structures are not limited to the work scaffolding 210, and may be other three-dimensional structures. [Explanation of symbols]
