[Effects of the Invention] 【0008】 According to the present invention, the wiring space can be expanded. [Brief explanation of the drawing] 【0009】 [Figure 1] This is a schematic cross-sectional view of a building equipped with a wiring structure according to an embodiment of the present invention. [Figure 2] This is a side view of a wiring structure according to an embodiment of the present invention. [Figure 3] This is a cross-sectional view along the line III-III in Figure 2. [Figure 4] Figure 2 shows a cross-sectional view along the line IV-IV, where (a) shows the second flooring material in a closed state and (b) shows the second flooring material in an open state. 【0010】 Hereinafter, a wiring structure 100, a building 1, and a method for constructing building 1 according to embodiments of the present invention will be described with reference to the drawings. Building 1 is, for example, a facility such as an indoor stadium or a theater. Building 1 may also be a commercial facility having an open atrium space. 【0011】 Figure 1 is a schematic cross-sectional view of building 1. As shown in Figure 1, building 1 is constructed on the ground. Building 1 comprises a building frame 2. The building frame 2 includes a plurality of columns 3, a truss 4 supported by the columns 3, and a roof 5 supported by the truss 4. The columns 3 are, for example, made of steel. The truss 4 is formed by a plurality of steel frames. 【0012】 Building 1 includes a wiring structure 100 attached to the building frame 2. The wiring structure 100 is supported by a truss 4. In the example shown in Figure 1, the wiring structure 100 extends in the direction perpendicular to the plane of the paper in Figure 1. Hereafter, the direction in which the wiring structure 100 extends will be referred to as the "longitudinal direction," and the horizontal direction perpendicular to the longitudinal direction will be referred to as the "width direction." 【0013】 Figure 2 is a side view of the wiring structure 100 as seen from the direction indicated by arrow II in Figure 1. Wiring W is laid on the wiring structure 100. As shown in Figure 2, the wiring structure 100 is fixed to the lower chord member 4a of the truss 4. The wiring structure 100 is connected to a suspension member 4b suspended from the upper chord member (not shown) of the truss 4. The wiring structure 100 is held at a high place (for example, 20 m above the ground) by the lower chord member 4a and the suspension member 4b. Therefore, wiring W can be laid at a high place. 【0014】 Figure 3 is a cross-sectional view taken along the line III-III shown in Figure 2. As shown in Figures 2 and 3, the wiring structure 100 comprises a walkway floor 10 and a first beam member 20 and a second beam member 30 provided below the walkway floor 10. 【0015】 The walkway floor 10 extends in the longitudinal direction. The walkway floor 10 is designed to allow workers to walk on it. Workers can perform work in the space above the ceiling on the walkway floor 10. Work in the space above the ceiling includes, for example, equipment inspection and replacement. 【0016】 The first beam member 20 and the second beam member 30 extend in the longitudinal direction. The first beam member 20 and the second beam member 30 are arranged at intervals in the width direction. A plurality of joist members 40 are spanned between the first beam member 20 and the second beam member 30. The joist members 40 are arranged at intervals in the longitudinal direction. The first beam member 20 and the second beam member 30 support the corridor floor 10 via the joist members 40. 【0017】 The wiring laying structure 100 further includes a plate member 50 as a wiring member provided between the first beam member 20 and the second beam member 30. The plate member 50 is formed such that the wiring W can be placed thereon. The plate member 50 is provided across the first beam member 20 and the second beam member 30. The plate member 50 may be a steel plate or a facing material other than the steel plate. Also, a plastic mesh sheet or the like may be placed on the plate member 50 for improving the appearance from below and the workability. 【0018】 The first beam member 20 has a web 21, an upper flange 22, and a lower flange 23. The upper flange 22 is provided at the upper end of the web 21. The lower flange 23 is provided at the lower end of the web 21. The second beam member 30, similar to the first beam member 20, has a web 31, an upper flange 32, and a lower flange 33. The plate member 50 is provided across the lower flange 23 and the lower flange 33. The plate member 50 is fixed to the lower flange 23 and the lower flange 33 by welding. The plate member 50 may be fixed to the lower flange 23 and the lower flange 33 via fastening members. The fastening members are, for example, bolts and nuts. 【0019】 Thus, in the wiring laying structure 100, the plate member 50 is provided between the first beam member 20 and the second beam member 30. Therefore, the wiring space is formed below the corridor floor 10. Accordingly, the wiring space can be enlarged regardless of the thickness of the corridor floor 10. Also, since the wiring arranged above the corridor floor 10 can be reduced, the workability and safety on the corridor floor 10 can be improved. 【0020】 The plate 50 is provided across the first beam 20 and the second beam 30. Therefore, the wiring space formed between the first beam 20 and the second beam 30 is closed off by the plate 50. Thus, the wiring W can be securely held in place by the wiring space of the wiring structure 100. 【0021】 The wiring structure 100 further comprises handrails 60a and 60b. The handrails 60a and 60b are spaced apart from each other in the width direction. Although not shown in the figures, a wiring space may be provided in at least one of the handrails 60a and 60b. 【0022】 The handrail 60a includes a plurality of handrail posts 61, an upper rail 62, a lower rail 63, and a middle rail 64. The handrail posts 61 are spaced apart in the longitudinal direction. The handrail posts 61 are fixed to the first beam member 20 via rib plates 65. The rib plates 65 are fixed to the first beam member 20, for example, by welding. The handrail posts 61 are fixed to the rib plates 65 via fastening members. 【0023】 The upper rail 62, lower rail 63, and middle rail 64 are provided across multiple handrail posts 61. The upper rail 62 is fixed to the upper end of the handrail post 61. The lower rail 63 is positioned below the upper rail 62. The middle rail 64 is positioned between the upper rail 62 and the lower rail 63. 【0024】 Since the structure of handrail 60b is the same as that of handrail 60a, a detailed explanation will be omitted here. 【0025】 Although not shown in the illustration, the wiring structure 100 may also include other equipment such as lighting and air conditioning ducts. 【0026】 As shown in Figure 2, the walkway floor 10 includes a first flooring material 11, a second flooring material 12, and a third flooring material 13. The first flooring material 11, the second flooring material 12, and the third flooring material 13 are arranged in the longitudinal direction. The second flooring material 12 is positioned between the first flooring material 11 and the third flooring material 13. The first flooring material 11 and the third flooring material 13 are fixed to the joists 40. The second flooring material 12 is attached to the joists 40 so as to be openable and closable. 【0027】 Figure 4 is a cross-sectional view along the line IV-IV shown in Figure 2. Figure 4(a) shows the second floorboard 12 in the closed position. Figure 4(b) shows the second floorboard 12 in the open position. As shown in Figure 4, the second floorboard 12 and the joist 40 are attached via hinges 41. The hinges 41 are, for example, slip-in hinges. 【0028】 The hinge 41 has a pair of plate sections that are rotatably connected to each other. One of the plate sections is attached to the end of the second flooring material 12 in the width direction. The other plate section is attached to the joist 40. The hinge 41 allows the second flooring material 12 to be rotatably attached to the joist 40 about the axis of rotation of the hinge 41. 【0029】 As shown in Figure 4(b), when the second flooring material 12 is open, the space between the first beam 20 and the second beam 30 (wiring space) is accessible from above. Therefore, workers can perform work on the wiring W in the wiring space from above the walkway floor 10. Since the wiring space is located below the walkway floor 10, safety can be increased compared to performing work above the walkway floor 10. 【0030】 In the example shown in Figure 4, the second flooring material 12 is of the double-door type. The present invention is not limited to this form. For example, the second flooring material 12 may be of the sliding type. 【0031】 Next, the construction method for building 1 will be described. In the construction method for building 1, the wiring structure 100 is assembled at a low level (for example, on the ground). The building frame 2 of building 1 is constructed separately from the assembly of the wiring structure 100. 【0032】 First, a first beam member 20 and a second beam member 30 are installed below the walkway floor 10 via joists 40, and the walkway floor 10 is supported by the first beam member 20 and the second beam member 30. At this time, the first beam member 20 and the second beam member 30 are spaced apart in the width direction. In addition, a plate member 50 is installed between the first beam member 20 and the second beam member 30. This forms the wiring laying structure 100. 【0033】 Next, the wiring W is placed on the board material 50. The wiring structure 100 is lifted and attached to the building frame 2 of the already constructed building 1. With this, the construction of building 1 is completed. After the wiring structure 100 is attached to the building frame 2, the wiring W laid on the wiring structure 100 is connected to the wiring (not shown) laid on the building frame 2. 【0034】 In the construction method according to this embodiment, the assembly of the wiring structure 100 and the laying of the wiring W in the wiring structure 100 are performed at a low level. Therefore, work at high levels is reduced, and safety and workability can be improved. 【0035】 According to the above embodiments, the following effects and advantages are achieved. 【0036】 In the wiring structure 100, a plate 50 is provided between the first beam 20 and the second beam 30. As a result, the wiring space is formed below the walkway floor 10. Therefore, the wiring space can be expanded regardless of the thickness of the walkway floor 10. In addition, since the amount of wiring to be placed above the walkway floor 10 can be reduced, workability and safety on the walkway floor 10 can be improved. 【0037】 In the wiring structure 100, the plate material 50 is provided across the first beam material 20 and the second beam material 30. Therefore, the wiring space formed between the first beam material 20 and the second beam material 30 is closed off by the plate material 50. Thus, the wiring W can be securely held in place by the wiring space of the wiring structure 100. 【0038】 In the wiring installation structure 100, the second floor material 12 is openable and closable, and when open, it provides access from above to the space between the first beam 20 and the second beam 30. Therefore, workers can perform work on the wiring W in the wiring space from above the walkway floor 10. Since the wiring space is located below the walkway floor 10, safety can be enhanced compared to performing work above the walkway floor 10. 【0039】 In the construction method for building 1, after assembling the wiring structure 100 and laying the wiring W within the wiring structure 100, the wiring structure 100 is lifted and attached to the building frame 2 of building 1. Therefore, the assembly of the wiring structure 100 and the laying of the wiring W within the wiring structure 100 can be performed at a low level. Consequently, work at high altitudes is reduced, improving safety and workability. 【0040】 In the above embodiment, the first flooring material 11 and the third flooring material 13 are not openable or closable. In the present invention, the first flooring material 11 and the third flooring material 13 may be openable or closable. That is, at least a part of the walkway floor 10 may be openable or closable, and when open, it may be possible to access the space between the first beam 20 and the second beam 30 from above. 【0041】 The assembly of the wiring structure 100 and the laying of the wiring W may be carried out on the building frame 2. More specifically, after attaching the first beam member 20 and the second beam member 30 to the building frame 2, a plate member 50 is provided between the first beam member 20 and the second beam member 30. The wiring structure 100 is also formed by this procedure. The plate member 50 may be joined to the first beam member 20 and the second beam member 30 by welding, or it may be fastened to the first beam member 20 and the second beam member 30 by fastening means. The wiring W is laid on the plate member 50 after it has been provided between the first beam member 20 and the second beam member 30. 【0042】 Although embodiments of the present invention have been described above, these embodiments only represent a part of the application examples of the present invention, and are not intended to limit the technical scope of the present invention to the specific configurations of the above embodiments.
