Description

Technical Field

[0001] The present invention relates to a laying path forming tool for forming a laying path for wiring and piping materials along the longitudinal direction, and a wiring and piping material laying path structure.

Background Art

[0002] Conventionally, when wiring and piping materials are installed in a building, a part of a long steel shape that constitutes a beam or the like provided in the building is used as a laying surface to form a laying path for the wiring and piping materials, and the wiring and piping materials are laid along the laying path. And various means are used to form the laying path for the wiring and piping materials in the steel shape.

[0003] For example, Patent Document 1 discloses a holder for laying wiring and piping materials along the mounting surface of a structural steel by holding the wiring and piping materials to the structural steel. In the following paragraph, the reference numerals of Patent Document 1 are shown in parentheses. The holder (31) is formed integrally with a clip by bending a resilient metal strip, with the upper plate (33) formed by bending upward in an arc shape from the right end of the lower plate (32), and the fixing plate (34) formed by folding downward from the left end of the lower plate (32). The upper plate (33) and the lower plate (32) are facing each other, and a holding portion (35) is formed between them for elastically clamping and holding the cable (61). The holder (31) further has a pull-out prevention portion (36) formed at the end of the upper plate (33) that bends toward the lower plate (32) to prevent the cable (61) from coming out of the holding portion (35). The end of the upper plate (33) is bent in a V-shape in the center, and an insertion guide portion (37) is formed at the tip to guide the insertion of the cable (61). The holder (31) is designed so that when the insertion guide portion (37) at the tip is pinched and spread open, the cable (61) is pushed in through the opening (39) formed therein, and the cable (61) is held in place by being squeezed from both above and below by the elastic restoring force of the upper plate (33) and the lower plate (32) while it is inserted inside the holding portion (35). On the other hand, the fixing plate (34) is formed by bending it into a roughly V-shape, and by pressing it against the edge of the flange (52) of the structural steel (51) and forcibly pushing it in, the gap between the fixing plate (34) and the lower plate (32) is widened, and when the flange (52) is housed in the space between the lower plate (32) and the fixing plate (34) through the insertion opening (40) formed therein, the flange (52) is held from both the upper and lower sides by the elastic restoring force, and the holder (31) is fixed to the flange (52). In order to arrange the cable (61) along the arrangement surface (53) of the structural steel (51) using the holder (31), first, multiple holders (31) are attached to the flange (52) of the structural steel (51) at predetermined intervals along the arrangement path. The installation can be performed by pushing the insertion opening (40) between the fixing plate (34) and the lower plate (32) of the retainer (31) toward the flange (52) of the structural steel (51).Next, when the cable (61) is pushed in through the insertion opening (39) of the holder (31), the cable (61) is held between the upper plate (33) and the lower plate (32) of the holder (31) and positioned along the mounting surface (53) of the structural steel (51).

[0004] [Patent Document 1] Japanese Patent Publication No. 2015-17696 [Overview of the Initiative] [Problems that the invention aims to solve]

[0005] In the holder described in Patent Document 1, it was necessary to lay long wiring and piping materials by sequentially holding them in multiple holders attached to structural steel along the installation route. In particular, if a worker tried to place the wiring and piping materials on the installation surface (for example, temporary wiring) before starting work, parts of the wiring and piping materials were likely to slip off the installation surface and fall off, making it difficult to maintain the wiring and piping materials in place while working. Therefore, workers had to simultaneously perform the task of holding the parts of the wiring and piping materials to each holder and the task of laying parts of the wiring and piping materials on the installation surface. In other words, workers could not perform the work procedure of laying the wiring and piping materials on the installation surface and then holding them, which resulted in poor work efficiency.

Effect of the Invention

[0017] According to one embodiment (Configuration 1) of the present invention, a wiring and piping material laying path structure is formed on the lower flange of a structural steel by fixing two or more laying path forming devices to the lower flange of the structural steel, and wiring and piping materials can be laid in the laying path. In particular, the first surface of the partition wall portion of the laying path forming device fixed to the lower flange, the upper surface (layout surface) of the lower flange, and the side surface of the web cooperate to form a laying space, and an introduction opening is formed between the lower surface of the upper flange and the tip portion of the partition wall portion for introducing wiring and piping materials into the laying space. That is, workers can efficiently perform laying work by placing wiring and piping materials into the laying space on the lower flange through the introduction opening. Therefore, the wiring and piping material laying path structure of the present invention forms a laying path for laying wiring and piping materials along a structural steel, and improves the workability in wiring and piping material laying work.

[0018] According to a further embodiment (configuration 2) of the present invention, in addition to the effects of the wiring and piping material laying path structure of configuration 1, even when a partition wall is provided on the structural steel, at least one of the multiple laying path forming devices is fixed to the partition wall via a fixing part so that the partition wall portion faces the side surface of the web, thereby forming an overhang laying path that allows the wiring and piping material to move over the partition wall from the laying space on one side in the longitudinal direction to the laying space on the other side. In other words, by arranging the wiring and piping material via the overhang laying path, damage to the wiring and piping material from contact with the end surface of the partition wall is suppressed.

[0019] According to a further embodiment (configuration 3) of the present invention, in addition to the effects of the wiring and piping material laying path structure of configuration 1 or 2, if the laying path is formed to extend from a first laying space facing one side of the web in the width direction to a second laying space facing the other side of the web in the width direction, at least two of the plurality of laying path forming devices can be fixed to one end and the other end of the upper flange in the width direction, respectively, thereby forming a bypass laying path for laying wiring and piping materials from the first laying space to the second laying space by bypassing the upper flange. That is, by arranging the wiring and piping materials via the bypass laying path, the wiring and piping materials can be laid from the first laying space to the second laying space by bypassing the upper flange.

[0020] According to a further embodiment (configuration 4) of the present invention, in addition to the effects of the wiring and piping material laying path structure of configuration 3, by connecting the first and second laying spaces, which are formed at positions offset in the longitudinal direction, with a bypass laying path, it is possible to form a wiring and piping material laying path that extends across both sides of the H-shaped steel as needed.

[0021] According to a further embodiment (configuration 5) of the present invention, by fixing the laying path forming tool to the lower flange of a structural steel via a fixing part, a laying path for wiring and piping materials is formed on the lower flange, making it possible to arrange the wiring and piping materials in the laying path. In particular, the first surface of the partition wall portion of the laying path forming tool fixed to the lower flange, the upper surface (arrangement surface) of the lower flange, and the side surface of the web cooperate to form a laying space, and an introduction opening can be formed between the lower surface of the upper flange and the tip portion of the partition wall portion for introducing wiring and piping materials into the laying space. That is, the worker can efficiently perform the laying work by arranging the wiring and piping materials in the laying space on the lower flange through the introduction opening. Therefore, the laying path forming tool of the present invention makes it possible to form a laying path for laying wiring and piping materials along a structural steel and improve the workability in the laying work of wiring and piping materials.

[0022] According to a further embodiment (configuration 6) of the present invention, in addition to the effects of the path-laying tool of configuration 5, when fixing the fixing part to the lower flange, the fastening part is fastened to the end face of the lower flange, thereby determining the minimum proximity distance between the first surface of the partition wall and the side surface of the web, and preventing the width of the laying space from becoming too narrow.

[0023] According to a further embodiment (configuration 7) of the present invention, in addition to the effects of the path forming tool of configuration 6, the tip portion of the partition wall in the vertical direction is inclined so as to be closer to the web than the latch portion when the fixing portion is fixed to the lower flange. This narrows the width of the introduction opening so that wiring and piping materials are less likely to detach from the laying space, while ensuring sufficient distance between the first surface of the partition wall and the side of the web (width of the laying space). Furthermore, because the tip portion of the partition wall in the vertical direction is inclined toward the first surface, when the path forming tool is fixed to a part other than the lower flange of the structural steel, the second surface can function to assist in the crossing of wiring and piping materials (see configuration 2).

[0024] According to a further embodiment (configuration 8) of the present invention, in addition to the effects of the path-laying tool of configuration 7, the lateral edges of the partition wall portion are curved (or inclined) toward the opposite side of the first surface compared to the central portion, thereby forming a recess in the lateral center of the second surface. This prevents wiring and piping materials from detaching from the lateral outer side of the second surface and assists in crossing over wiring and piping materials using the second surface (see configuration 2).

[0025] According to one embodiment (configuration 9) of the present invention, the fixing part is configured to be selectively fixed to any part of the H-shaped steel. When the fixing part is selectively fixed to the lower flange, the first surface of the partition wall part faces the side surface of the web at a distance from it, and the first surface of the partition wall part, the upper surface of the lower flange, and the side surface of the web cooperate to define the space for laying wiring and piping materials. On the other hand, when the fixing part is selectively fixed to the partition wall of the H-shaped steel, the first surface of the partition wall part faces the side surface of the web at a distance from it, and an overpass laying path is formed for the wiring and piping materials to cross over the partition wall longitudinally via the second surface of the partition wall part. In other words, the laying path forming tool of the present invention can be used in different forms depending on its intended use, and as a result, it is possible to improve the workability in the laying of wiring and piping materials.

[0026] According to a further embodiment (configuration 10) of the present invention, in addition to the effects of any of the path-laying devices of configurations 5 to 9, the path-laying device can be fixed to any part of the structural steel by a fixing mechanism in which the clamping portion clamps the plate-shaped portion of the structural steel in the vertical direction. Furthermore, the clamping portion can firmly clamp the structural steel by fastening a bolt body. [Brief explanation of the drawing]

[0028] One embodiment of the present invention will be described below with reference to the drawings. Note that the shapes in the drawings referenced in the following description are conceptual or schematic diagrams for illustrating preferred shapes and dimensions, and the dimensional ratios, etc., do not necessarily correspond to actual dimensional ratios. In other words, the present invention is not limited to the dimensional ratios shown in the drawings. Furthermore, the up, down, left, and right directions in the present invention are merely concepts indicating relative positions, and it goes without saying that they can be interchanged and applied accordingly.

[0029] One embodiment of the present invention, the laying path forming device 100, is used to form a laying path for wiring and piping materials along a longitudinally extending structural steel installed in a building by being fixed in multiple locations to the structural steel. In this embodiment, the structural steel to which the laying path forming device 100 is fixed is an H-shaped steel 11, but the present invention is not limited thereto. Also, in this embodiment, the wiring and piping materials are exemplified as cables 18 and 19, but the present invention is not limited thereto, and for example, the wiring and piping materials may be piping materials such as protective pipes or fluid pipes. Here, the wiring and piping material laying device is composed of an H-shaped steel 11 and a plurality of laying path forming devices 100, and is a device that forms a laying path for wiring and piping materials and enables the laying of cables (wiring and piping materials). Furthermore, the wiring and piping material laying path structure (also abbreviated as laying path structure) 10 is an installation structure in which a predetermined laying path is constructed by fixing a plurality of laying path forming devices 100 to the H-shaped steel 11 installed in the building.

[0030] Generally, an H-shaped steel beam 11 is a long body extending in the longitudinal direction, and the cross section cut along the width direction perpendicular to the longitudinal direction has an H shape, and this H-shaped cross section shape is continuous in the longitudinal direction. Specifically, as shown in Figure 8, the H-shaped steel beam 11 has a cross-sectional shape comprising a lower flange 12 extending substantially horizontally in the width direction, an upper flange 13 extending parallel to the lower flange 12 in the width direction, and a web 14 extending in the height direction so as to connect the lower flange 12 and the upper flange 13 approximately midway in the width direction. The upper surface of the lower flange 12 defines the cable arrangement surface. In this embodiment, cable laying spaces are formed in the spaces facing both sides of the web 14. Also in this embodiment, as shown in Figure 9, the H-shaped steel beam 11 is provided with a partition wall 15 that separates the space on the lower flange 12 facing one side of the web 14 in the longitudinal direction. The bulkhead 15 is joined to the upper surface of the lower flange 12, the lower surface of the upper flange 13, and one side of the web 14 by welding or other means. This bulkhead 15 is generally called a rib plate and is a plate portion that reinforces the H-shaped steel 11.

[0031] The configuration of the road laying tool 100 according to one embodiment of the present invention will be described with reference to Figures 1 to 5. Figures 1(a) and 1(b) are schematic perspective views of the road laying tool 100 as seen from the front and rear sides. Here, the side with the second surface 113b of the road laying tool 100 is considered the front side. Figures 2(a) and 2(b) are the front and rear views of the road laying tool 100. Figures 3(a) to 3(c) are the plan, side, and bottom views of the road laying tool 100. Figures 4(a) and 4(b) are the AA and BB cross-sectional views of Figure 2(a). Figure 5 is an exploded perspective view of the road laying tool 100.

[0032] One embodiment of the cable laying path forming tool 100 includes a fixing part fixed to an H-shaped steel beam 11, and a partition wall part 113 that, with the fixing part fixed to the lower flange 12, rises in the vertical direction facing the web 14 and spaced apart from the fixing part, and cooperates with the upper surface of the lower flange 12 and the side surface of the web 14 to form a laying space for laying cables. As shown in Figure 5, the cable laying path forming tool 100 is constructed by assembling a fixing body 101 on which the fixing part is provided and a partition wall body 111 on which the partition wall part 113 is provided. In other words, the fixing body 101 and the partition wall body 111 are separate components. Figures 6(a) to 6(e) are the front view, top view, bottom view, side view, and rear view of the fixing body 101. Figures 7(a) to 7(e) are the front view, top view, bottom view, side view, and rear view of the partition wall body 111. Each component will be described in detail below.

[0033] As shown in Figures 5 and 6, the fixing body 101 is formed in a roughly U-shape in side view, with one side (the rear side) open. The fixing body 101 comprises a lower wall portion 101a, a vertical wall portion 101b, and an upper wall portion 101c. The fixing body 101 is also configured to sandwich the edge of the plate-like portion of the H-shaped steel 11 between the lower wall portion 101a and the upper wall portion 101c through the open portion on one side.

[0034] The fixing portion includes a clamping portion 102 and a bolt body 103 that cooperates with the clamping portion 102 to clamp the edge of the plate-shaped portion of the H-shaped steel 11 by screwing. The clamping portion 102 is formed on the lower surface of the upper wall portion 101c of the fixing body 101 and is configured to contact the plate-shaped portion of the H-shaped steel 11. Here, the clamping portion 102 has multiple sawtooth teeth on its lower surface in order to contact the plate-shaped portion of the H-shaped steel 11 without slipping. In addition, the upper wall portion 101c has a connected portion 106 which is connected to a concave connecting portion 116 of the partition wall 111. Furthermore, the lower wall portion 101a has a threaded portion 104 through which the bolt body 103 is screwed. The tip surface of the shaft portion of the bolt body 103 and the clamping portion 102 face each other parallel to one another, and the plate-shaped portion of the H-shaped steel 11 can be clamped by the screwing of the bolt body 103. In addition, the fixing body 101 has slit-shaped and octagonal through holes, which are holes for attaching cable ties (fastening members) for tying cables.

[0035] Furthermore, while the upper wall portion 101c of the fixed body 101 is located inside the partition wall 111, the lower wall portion 101a and the vertical wall portion 101b are exposed to the outside. The outer surfaces of the lower wall portion 101a and the vertical wall portion 101b are formed by combining curved and flat portions so as not to have sharp corners, as cables may come into contact with them when forming the overhang laying path T, as will be described later. In other words, the corners of the fixed body 101 are formed with curved surfaces to prevent damage to the cables that come into contact with them.

[0036] As shown in Figures 5 and 7, the partition wall 111 is formed in a flat shape and comprises a covering portion 112 configured to cover the upper surface of the fixed body 101, and a partition wall portion 113 erected at a predetermined vertical length in a direction away from the covering portion 112.

[0037] The cover portion 112 is configured to cover the upper surface of the fixing body 101 on the front side (first surface 113a) of the partition wall body 111, thereby avoiding direct contact between the fixing body 101 and the cable. The upper surface of the cover portion 112 has a mounting surface 112a on which the cable can be placed. This mounting surface 112a is curved so as not to damage the cable that it comes into contact with. The rear side (second surface 113b) of the cover portion 112 has a concave connecting portion 116 for inserting and connecting the connecting portion 106 of the fixing body 101. The lower surface of the cover portion 112 has a second clamping portion 114 that contacts the surface of the plate-shaped portion of the H-shaped steel 11 and clamps the plate-shaped portion of the H-shaped steel 11 together with the clamping portion 102 of the fixing body 101. Furthermore, the lower surface of the cover portion 112 has a hooking portion 115 that protrudes downward from the rear end. The latching portion 115 is configured to latch the road laying tool 100 to the end face of the plate-shaped portion of the H-shaped steel 11. As will be described later, when the first surface 113a of the plate-shaped partition wall portion 113 is fixed facing the web 14, the latching portion 115 latches to the end face of the lower flange 12 and functions to determine the minimum proximity distance between the first surface 113a and the side surface of the web 14.

[0038] The partition wall portion 113 is a plate-like portion erected from the cover portion 112 at a predetermined vertical length. When fixed to the H-shaped steel 11, the partition wall portion 113 has a first surface 113a facing the side of the web 14 and a second surface 113b facing the opposite side. The first surface 113a and the second surface 113b are substantially rectangular in shape. In other words, a cable laying space can be partitioned between the first surface 113a of the opposing partition wall portion 113 and the side of the web 14. Furthermore, when the cover portion 112 is fixed on the lower flange 12, the partition wall portion 113 has a vertical length that allows an introduction opening for passing a cable between the tip portion of the partition wall portion 113 and the upper flange 13. In other words, the erection length of the partition wall portion 113 was set to be lower than the height of the web 14 so that when the covering portion 112 is fixed on the lower flange 12, it does not completely cover the side of the web 14 in the height direction.

[0039] As shown in Figure 4(a), the partition wall portion 113 has a curved portion in a cross-section cut along the vertical direction. The base end portion of the partition wall portion 113 in the vertical direction is erected substantially perpendicular to the cover portion 112, while the tip end portion in the vertical direction curves in a gentle arc and slopes forward. In particular, the tip end portion of the partition wall portion 113 in the vertical direction is inclined such that the upper end of its first surface 113a is located at least in front of the hook portion 115. In this embodiment, in a side view, the tip of the partition wall portion 113 and the front end of the cover portion 112 are in approximately the same position. That is, when the road laying tool 100 is fixed to the lower flange 12, the partition wall portion 113 is configured such that the upper end of its first surface 113a is closer to the side surface of the web 14 than the hook portion 115.

[0040] As shown in Figure 4(b), the partition wall portion 113 also has a curved portion in a cross-section cut in the transverse direction perpendicular to the vertical direction. The transverse edges of the partition wall portion 113 perpendicular to the vertical direction are curved (or inclined) toward the opposite side of the first surface 113a compared to the central portion between the two edges. That is, on the first surface 113a, the transverse edges are recessed toward the rear, and on the second surface 113b, a recess is formed in which the transverse central portion is recessed toward the front. As will be described later, this recess makes it possible to secure the cable closer to the center of the second surface 113b when the laying path forming tool 100 is fixed to the partition wall 15.

[0041] Furthermore, the partition wall 111, like the fixing body 101, has multiple through-holes such as slits, which are holes for attaching cable ties (fastening members) to tie up cables.

[0042] Next, we will describe a cable laying structure 10 in which cables 18 and 19 are laid along two laying paths by fixing multiple laying path forming devices 100 to the H-shaped steel beams 11 installed in the building.

[0043] Figure 8 is a schematic perspective view of the cable routing structure 10 as seen from one side of the web 14 of the H-shaped steel beam 11. Figure 9 is a schematic perspective view of the cable routing structure 10 as seen from the other side of the web 14 of the H-shaped steel beam 11. As shown in Figures 8 and 9, the cable routing structure 10 has cable routing paths for laying cables 18 and 19 provided on both sides of the H-shaped steel beam 11. The cable routing paths are also provided to be continuous in the longitudinal direction of the H-shaped steel beam 11. In particular, the cable routing structure 10 has a first cable routing path S that extends only to one side of the web 14, and a second cable routing path T that extends continuously from one side of the web 14 to the other side. The wiring and piping material laid in the first cable routing path S is called cable 18, and the wiring and piping material laid in the second cable routing path T is called cable 19.

[0044] As shown in Figures 8 and 10, the first laying path S is a laying path that extends linearly along one side of the web 14. Multiple laying path forming devices 100 are fixed at predetermined intervals to the outer edge of the lower flange 12 of the H-shaped steel 11. Also, as shown in Figure 11, each laying path forming device 100 is fixed to the lower flange 12 by clamping parts 102, 114 and bolt bodies 103 that clamp the plate-like portion of the lower flange 12. At this time, the first surface 113a of the partition wall 113 faces the side surface of the web 14, and an introduction opening is formed between the tip of the partition wall 113 in the vertical direction and the tip edge of the upper flange 13, allowing the cable 18 to pass through. In addition, the fixing position in the width direction of the laying path forming device 100 is determined by the hooking part 115 hooking onto the end face of the lower flange 12, and the first surface 113a and the side surface of the web 14 are separated by a predetermined distance. Furthermore, a laying space for laying the first cable 18 is formed by the first surface 113a of the partition wall 113, the upper surface of the lower flange 12, and the side surface of the web 14. Multiple cables 18 are then routed in a straight line along the first laying path S.

[0045] As shown in Figures 8 and 9, the second laying path T is formed to extend across both sides of the web 14 of the H-shaped steel beam 11. As shown in Figure 11, the first cable 18 is routed to the upper surface of the lower flange 12 on the widthwise inner side of the partition wall portion 113, while the second cable 19 is routed to the mounting surface 112a of the cover portion 112 of the laying path forming device 100. In other words, the cable may be arranged on either the upper surface of the lower flange 12 or the mounting surface 112a of the cover portion 112. Furthermore, as shown in Figure 11, when routing the cable 19 onto the mounting surface 112a, it is possible to fix and route the cable 19 onto the mounting surface 112a by attaching a cable tie 118 as a fastening member to the laying path forming device 100 through a through hole and surrounding the cable 19 with the cable tie 118. In the cable laying structure 10 of this embodiment, the cable 18 routed along the first cable laying path S is separated onto the lower flange 12, and the cable 19 routed along the second cable laying path T is separated onto the mounting surface 112a.

[0046] Furthermore, in the laying path structure 10 of this embodiment, the second laying path T extends from a branching point in the middle of the first laying path S to the opposite side of the web 14. That is, the second laying path T has a first laying space T1 on one side of the web 14 and a second laying space T2 on the other side of the web 14. As shown in Figure 10, the first laying space T1 is shared with a part of the laying space of the first laying path S. The first laying space T1 and the second laying space T2 are formed at positions offset in the longitudinal direction of the H-shaped steel 11 and are connected by a bypass laying path U. Then, a part of the multiple cables 18, 19 (cable 19) bends upward from the first laying space T1 at the branching point and is routed to the upper surface of the upper flange 13.

[0047] As shown in Figures 12 to 14, at least two of the multiple laying path forming devices 100 are fixed to one end and the other end of the upper flange 13 in the width direction via fixing parts, and each of the partition wall portions 113 is erected above the upper flange 13, thereby forming a bypass laying path U for laying the cable 19 from the first laying space T1 to the second laying space T2 by bypassing the upper flange 13. At this time, the laying path forming device 100 on one end in the width direction and the laying path forming device 100 on the other end in the width direction are fixed spaced apart in the longitudinal direction in order to form the first laying space T1 and the second laying space T2 at positions offset in the longitudinal direction.

[0048] As shown in Figure 14, each road laying device 100 is fixed to the upper flange 13 by the clamping parts 102 and 114 and the bolt body 103 clamping the plate-shaped portion of the upper flange 13. In addition, the fixing position of the road laying device 100 in the width direction is determined by the hooking part 115 being hooked onto the end face of the upper flange 13. As shown in Figure 13, the first surfaces 113a of the partition wall portion 113 on one end and the other end in the width direction of the upper flange 13 face each other in the width direction, and a bypass space for the cable 19 is defined between them. In other words, the cable 19 extending from the first laying space T1 to the upper surface side of the upper flange 13 comes into contact with the bent portion of the first surface 113a of the partition wall portion 113 on the one end in the width direction and passes across the upper surface of the upper flange 13 in the width direction. The cable 19 then abuts against the first surface 113a of the partition wall portion 113 on the other end in the width direction, and then bends downwards toward the upper flange 13 and is routed into the second laying space T2 (which is longitudinally separated from the first laying space T1).

[0049] Furthermore, in the cable laying structure 10 of this embodiment, as shown in Figures 15 to 17, a partition wall 15 is formed in the second laying space T2 of the second cable laying path T, separating the laying space in the longitudinal direction. At least two of the multiple cable laying tools 100 are fixed to the lower flange 12 in the spaces on both sides of the partition wall 15 in the longitudinal direction, and laying spaces are formed on one side and the other side of the partition wall 15 in the longitudinal direction. In contrast, the second cable laying path T includes an overpass cable laying path V for the cable 19 to cross the partition wall 15 from the laying space on one side to the laying space on the other side. That is, the overpass cable laying path V is formed by fixing at least one cable laying tool 100 to the partition wall 15 via a fixing part such that the partition wall portion 113 faces the side surface of the web 14.

[0050] As shown in Figure 17, the road laying tool 100 is fixed to the partition wall 15 by the clamping parts 102 and 114 and the bolt body 103 clamping the plate-shaped portion of the partition wall 15. In addition, the fixing position of the road laying tool 100 in the width direction is determined by the hooking part 115 hooking onto the end face of the partition wall 15, and the first surface 113a and the side surface of the web 14 are separated by a predetermined distance. The road laying tool 100 is arranged such that the first surface 113a of the partition wall portion 113 faces the side surface of the web 14, and the vertical direction of the partition wall portion 113 is aligned with the longitudinal direction of the H-shaped steel 11. The cable 19, which is routed linearly in the laying space on one side in the longitudinal direction, is bent outward in the width direction of the H-shaped steel 11 when it approaches the partition wall 15, and is routed over the partition wall 15 via the second surface 113b of the partition wall portion 113 of the laying path forming device 100 to the laying space on the other side in the longitudinal direction. Here, the partition wall body 111 covers the corner of the partition wall 15 from one side in the longitudinal direction, preventing the cable 19 from hitting the corner of the partition wall 15 and getting damaged. In addition, the partition wall portion 113 is inclined so as to be close to the side surface of the web 14 at its leading edge in the vertical direction, which assists in the cable 19 from crossing over. Furthermore, since both lateral edges of the partition wall portion 113 are curved toward the second surface 113b, the cable 19 is restricted from moving in the height direction (downward). The cable 19, having crossed the overpass laying path V, then bends inward in the width direction of the H-shaped steel 11 and is routed so as to pass inside the laying path forming device 100 on the other side in the longitudinal direction.

[0051] Next, with reference to Figures 18 to 20, a method for constructing a laying path structure 10 using the wiring and piping material laying device of this embodiment will be described. First, laying paths S and T are set for laying cables 18 and 19 on H-shaped steel beams 11 that make up the beams of the building. As shown in Figure 18, along the set laying paths S and T, the fixing points of the H-shaped steel beams 11 to which the laying path forming device 100 will be fixed are determined. Then, at each fixing point, the laying path forming device 100 is fixed to the plate-shaped portion of the H-shaped steel beam 11. As shown in Figure 19(a), the plate-shaped portion of the H-shaped steel beam 11 is inserted between the clamping parts 102 and 114 of the laying path forming device 100 and the bolt body 103, and the hooking part 115 is hooked onto the end face of the plate-shaped portion to position it. Note that in order to widen the laying space, the hooking part 115 may be positioned away from the end face of the plate-shaped portion. As shown in Figure 19(b), the road laying device 100 can be fixed to the H-beam 11 by tightening the bolt body 103 with a tool while maintaining the road laying device 100 in a fixed position. At this time, the worker can temporarily hold the road laying device 100 to the H-beam 11 simply by tightening the bolt body 103 with their fingers, so the fastening operation can be easily performed with a tool without having to grasp the road laying device 100 by hand. After fixing multiple road laying devices 100 to the H-beam 11 and forming a road for laying the cables 18, the cables 18 and 19 are routed into the laying space through an introduction opening that opens on the side of the H-beam 11, as shown in Figure 20. After temporarily placing the cables 18 and 19 in the laying space, they can be fixed to the road laying device 100 using cable ties 118 as needed. The road laying structure 10 can be constructed through the above steps.

[0052] The following describes the operation and effects of a laying path forming tool 100 and a wiring / piping material laying path structure 10 according to one embodiment of the present invention.

[0053] According to the cable laying path forming tool 100 and wiring / piping material laying path structure 10 of one embodiment of the present invention, by fixing two or more cable laying path forming tools 100 to the lower flange 12 of the H-shaped steel 11, cable laying paths S and T for cables 18 and 19 can be formed on the lower flange 12, and the cables 18 and 19 can be laid in the laying paths S and T. In particular, the first surface 113a of the partition wall portion 113 of the cable laying path forming tool 100 fixed to the lower flange 12, the upper surface (layout surface) of the lower flange 12, and the side surface of the web 14 cooperate to form a laying space, and an introduction opening is formed between the lower surface of the upper flange 13 and the tip portion of the partition wall portion 113 for passing the cable 18 through and introducing it into the laying space. That is, the worker can efficiently lay the cables 18 and 19 in the laying space on the lower flange 12 through the introduction opening. Therefore, the cable laying path forming tool 100 and the wiring / piping material laying path structure 10 of this embodiment form laying paths S and T for laying cables 18 and 19 along the H-shaped steel 11, thereby improving work efficiency in the cable laying work of the cables 18.

[0054] Furthermore, according to the laying path forming tool 100 and the wiring / piping material laying path structure 10 of this embodiment, the laying path forming tool 100 can serve as both a member that forms a laying space on the lower flange 12 and a member that forms a laying path V that overcomes the partition wall 15, making it possible to lay materials even if there is an obstacle such as a partition wall 15 in the middle of the laying path T. In addition, the laying path forming tool 100 can also serve as a member that forms a bypass laying path U that allows the cable 19 to be routed around to the upper surface of the upper flange 13 (or the lower surface of the lower flange 12) of the H-shaped steel 11. In other words, the laying path forming tool 100 forms a laying space and prevents the cable 19 from coming into contact with obstacles or flange end faces, thus preventing damage to the cable 19. Therefore, the laying path forming tool 100 and the wiring / piping material laying path structure 10 of this embodiment improve the workability of laying work.

[0055] The present invention is not limited to the embodiments described above, and various modifications are possible. Modifications of the present invention are described below.

In the above embodiment, the wiring and piping material laying path structure consists of an H-shaped steel and a plurality of laying path forming devices, and is constructed by fixing the plurality of laying path forming devices to the H-shaped steel, but the present invention is not limited thereto. For example, the steel shape is not limited to an H-shaped steel, but may be an I-shaped steel or a channel steel having a U-shaped cross-section. Figure 21 is a schematic perspective view of a laying path structure 20 of another embodiment of the present invention. The channel steel 21 comprises a lower flange 22, an upper flange 23, and a web 24 connecting the lower flange 22 and the upper flange 23 at the widthwise ends. The channel steel 21 is also provided with a partition wall 25 as a rib plate. As shown in Figure 21, a linear laying path for the cable 28 may be formed by fixing a plurality of laying path forming devices 100 to the lower flange 22 only on one side of the channel steel 21.

[0057] (2) The wiring and piping material laying path structure of the present invention is not limited to the configuration of the above embodiment. In the above embodiment, the partition wall is a rib plate integrally formed on the structural steel as an obstacle, but the present invention is not limited thereto. Figure 22 is a schematic perspective view of a laying path structure 30 of another embodiment of the present invention. The structural steel 31 comprises a first H-shaped steel that forms a laying path along the longitudinal direction and a second H-shaped steel perpendicular to the H-shaped steel. The structural steel 31, as the first H-shaped steel, comprises a lower flange 32, an upper flange 33, and a web 34 that connects the lower flange 32 and the upper flange 33 in the middle in the width direction. On the other hand, the second H-shaped steel forms two partition walls 35 that divide the laying space in the longitudinal direction as obstacles for cable 38 wiring. Against this, a plurality of wiring and piping material laying path forming devices 100 are fixed to the lower flange 32 and the partition walls 35, 35, thereby forming a laying path for the cable 39. Furthermore, the partition wall of the present invention refers to an obstacle that separates the space on the lower flange in the longitudinal direction, and its form is not limited to a specific structure.

[0058] (3) The road laying tool of the present invention is not limited to the configuration of the above embodiment. In the above embodiment, the fixing part of the road laying tool was fixed to the plate-shaped portion of the structural steel by clamping between the clamping part and the bolt body, but the present invention is not limited thereto. For example, the fixing part may be in the form of a clip that clamps the plate-shaped portion of the structural steel, or it may be magnetically attached to the structural steel by magnetic force. In other words, the fixing part can be selected from a variety of fixing means.

[0059] (4) The road laying tool of the present invention is not limited to the configuration of the above embodiments. In the above embodiments, the road laying tool is assembled by combining a fixed body and a partition wall body which are separate parts, but the present invention is not limited thereto. For example, the road laying tool may have a fixed part and a partition wall part which are integrally formed.

[0060] The present invention is not limited to the embodiments or modifications described above, and can be implemented in various forms as long as they fall within the technical scope of the present invention. That is, within the technical scope of the present invention, some of the configurations of this embodiment may be omitted or modified, or other configurations may be added. [Explanation of Symbols]
