Further, in the two erection members 60 arranged in each through hole forming member 50, the interval between the connecting pieces 63 facing each other is the same as the interval in the arrangement direction of the two wires 21 in the cloth fixture 20. Two erection members 60 are installed on each floor F1, F2, F3, F4, F5. For this reason, in the state in which the wire attachment U-bolt 65 is integrated with the connecting piece 63, the distance between the wire attachment U-bolts 65 facing each other in the longitudinal direction of the through-hole 11 is equal to the two in the cloth fixture 20. This is the same as the interval in the arrangement direction of the wires 21.

Next, the installation structure of the cloth fixture 20 having the above configuration will be described together with the operation.
As shown in FIG. 1, one laying tool 20 extends from the first floor F1 to the third floor F3, and one extending from the third floor F3 to the fifth floor F5.

A connecting bolt 71 is inserted from below. The connecting bolt 71 includes a male screw portion 71a and a ring 71b integrated with the male screw portion 71a. A nut 72 is screwed into the male screw portion 71 a inserted into the first cloth fixture fixing hole 61 b, and the connecting bolt 71 is fixed to the first installation piece 61. A U-shaped metal fitting 74 is hooked on the ring 71 b of the connecting bolt 71. The U-shaped metal fitting 74 includes through holes 74a at both ends of the U-shape.

  Then, the first connecting portion 22 is connected to the center in the longitudinal direction of the installation member 60 by hooking the first connecting portion 22 of the cloth fixture 20 on the fixing screw 75 screwed into the through hole 74a of the U-shaped fitting 74. The When the third floor F3 and the fifth floor F5 are viewed from the thickness direction, the connecting bolt 71 is disposed at a position overlapping the through hole 11. Specifically, the connecting bolt 71 includes both ends of the through hole 11 in the longitudinal direction and the short side. It is located on the inner side of both ends.

  The cloth fixture 20 is suspended from the third floor F3 and the fifth floor F5. The vicinity of the first connecting portion 22 of each cloth fixture 20 passes through the through hole 11 of the third floor F3 or the fifth floor F5. However, the two wires 21 are located inside the longitudinal direction both ends and the short direction both ends of the through hole 11 (through hole forming member 50), and are separated from the inner surfaces of the long walls 51 and the short walls 52.

  As shown in FIG. 8 or FIG. 9, in the erection member 60 of the first floor F1 or the third floor F3, the second second fabric fixture fixing in the center of the second fabric fixture fixing holes 62a of the second installation piece 62 A connecting bolt 71 is inserted into the hole 62a from above. The connecting bolt 71 includes a male screw portion 71a and a ring 71b integrated with the male screw portion 71a. The male threaded portion 71 a of the connecting bolt 71 is inserted into the second cloth fixture fixing hole 62 a, and a nut 72 is screwed into the male threaded portion 71 a, and the connecting bolt 71 is fixed to the second installation piece 62. .

  One end of the turnbuckle 73 in the axial direction is hooked on the ring 71 b that protrudes from the upper surface of the erection member 60. The second connecting portion 23 is hooked to the other axial end of the turnbuckle 73. Then, by tightening the turnbuckle 73, the wire 21 is pulled toward the first floor F1 or the third floor F3, and tension is applied to the wire 21. As a result, the cloth fixture 20 is stretched. The second connecting portion 23 side of each cloth fixture 20 is located above the floors F <b> 1 and F <b> 3 and is not located in the through hole 11. However, when the first floor F1 and the third floor F3 are viewed from the thickness direction, the turnbuckle 73 and the second connecting portion 23 are disposed at positions overlapping with the through holes 11, and both the longitudinal direction ends and the short direction ends of the through holes 11 are disposed. It is located more inside.

  In addition, the two cloth fixtures 20 arranged in the height direction of the building have the same spacing in the arrangement direction of the wires 21 and are stretched so that the wires 21 are aligned in the height direction of the building. ing. About each cloth fixture 20 in which the wires 21 are arranged in a straight line in the height direction of the building and the intervals in the arrangement direction of the two wires 21 are the same, in the wire intermediate portion C, the second floor F2 Or the straight part which penetrates the 4th floor F4 is hold | maintained at the construction member 60 installed in the 2nd floor F2 or the 4th floor F4.

  As shown in FIG. 10 (a), FIG. 10 (b) or FIG. 11, the wire mounting U-bolt 65 is inserted into the wire fixing hole 63a of the connecting piece 63 on each floor and penetrates the wire fixing hole 63a. A nut 66 is screwed onto the male screw of the wire mounting U-bolt 65 via a washer 66a. As a result, the wire-attaching U-bolt 65 is integrated with the connecting piece 63 positioned on the inner side from both longitudinal ends of the through hole 11. Therefore, the U-bolt 65 for wire attachment is disposed at a position protruding inward from both ends in the longitudinal direction of the through hole 11 by the installation member 60. As a result, each wire intermediate portion C is formed from both ends in the longitudinal direction of the through-hole 11 by an installation device including the laying tool 20, the erection member 60 having the U-bolt 65 for wire attachment, and the through-hole forming member 50. Are also held at positions projecting inward from the inner side and both ends of the through hole 11 in the short direction.

  That is, in the vicinity of the second floor F2 and the fourth floor F4, each wire 21 is held by the erection member 60 while the interval in the arrangement direction of the two wires 21 remains constant. Even if each wire 21 is held by the wire-mounting U-bolt 65 and the erection member 60, the interval in the alignment direction is not widened.

  As shown in FIG. 1, the wiring / pipe material laying path K in the building is formed by the laying tool 20 stretched on each floor as described above. A thermally expandable refractory material 80 is disposed between the inner surface of the through hole forming member 50 on each floor, that is, between the inner surface of the through hole 11 and the outer peripheral surface of the cable P. The heat-expandable refractory material 80 is formed in a block shape (more specifically, a rectangular parallelepiped shape). The heat-expandable refractory material 80 is flame retardant. When the heat-expandable refractory material 80 receives heat of 120 ° C. or higher, the volume expands to three times or more of that before heating.

  The cables P are laid along the respective laying tools 20 constituting the wiring / piping material laying path K, and the cables P are bound to the wiring / piping material support portions 31 of the respective laying tools 20. With this binding, the cable P is supported by the wiring / piping material support portion 31.

According to the above embodiment, the following effects can be obtained.
(1) The wiring / piping material laying path K of the building is formed by the two laying tools 20, but the portion immediately before passing through the through hole 11 in the wire intermediate portion C of each laying tool 20 is a wire. The mounting member 60 is held by the mounting U-bolt 65. For this reason, for example, when shaking occurs due to vibration such as an earthquake, the shaking of the wire intermediate portion C can be restricted by the erection member 60 and the U-bolt 65 for wire attachment, and the shaking of the wire 21 can be suppressed to a low level. . As a result, the wire 21 can be prevented from contacting the inner surface of the through hole forming member 50.

  (2) The wire intermediate portion C is held at positions spaced from both the longitudinal end faces and the transverse end faces of the through-hole 11 by the installation member 60 and the wire mounting U-bolts 65. For this reason, even if the wire 21 is shaken by vibration such as an earthquake, the wire 21 can be prevented from rubbing against the inner surface of the through hole forming member 50.

  (3) The through hole 11 has a rectangular shape, and the dimension in the longitudinal direction of the through hole 11 is longer than the dimension of the cloth fixture 20 along the arrangement direction of the two wires 21. For this reason, the cloth fixture 20 can be passed through the through hole 11. For example, as compared with the case where the wire 21 and the wiring / piping material support portion 31 are separated from each other in the cloth fixture 20 and the two wires 21 are stretched, then the wiring / piping material support portion 31 is attached to the wire 21. The installation of the cloth fixture 20 becomes easy.

  (4) The two erection members 60 installed in the through-hole forming member 50 are such that the interval between the opposing connecting pieces 63 is the same as the interval in the arrangement direction of the two wires 21 in the cloth fixture 20. Installed. For this reason, by integrating the wire-attaching U-bolts 65 in each erection member 60, the two wire-attachment U-bolts 65 can be arranged at the same interval as the interval in the arrangement direction of the two wires 21. .

  (5) The through hole 11 formed by the through hole forming member 50 is rectangular. For example, compared with the case where a round hole having a diameter in the longitudinal direction of the through-hole 11 is used as the through-hole, the opening area of the through-hole 11 can be reduced and the strength reduction of the floors F1 to F5 can be suppressed. .

  (6) The erection member 60 is disposed above the through hole forming member 50. For this reason, the U-bolt 65 for wire attachment can be fixed to the erection member 60 above the through hole 11, and the work of holding the wire intermediate portion C on the erection member 60 can be easily performed.

  (7) A thermally expandable refractory material 80 is filled between the inner surface of each through hole 11 and the outer peripheral surface of the cable P. For this reason, in the unlikely event that a fire occurs in the building, it is possible to prevent the thermally expandable refractory material 80 from expanding and causing smoke, flame, etc. that have passed through the through hole 11 to move to the upper floor.

  (8) The installation device for the fabric tool 20 includes the fabric tool 20, the through-hole forming member 50, and the erection member 60 including the wire-attaching U-bolt 65. A pedestal 55 is fixed to the through-hole forming member 50, and an erection member 60 is attached to the pedestal 55. The pedestal 55 includes three attachment holes 57a. Then, by adjusting the fixing position of the pedestal 55 with respect to the through-hole forming member 50 and selecting the attachment hole 57a for attaching the installation member 60, the interval between the two installation members 60 arranged in the through-hole formation member 50 is increased. The distance between the two wires 21 can be adjusted. As a result, the intermediate wire portion C can be held while the cloth tool 20 is stretched without widening or narrowing the distance between the two wires 21.

  (9) The wiring / piping material support portion 31 includes a support portion main body 32, an attachment member 34, and a cap 39. The cap 39 is detached from the support portion main body 32, and the attachment member 34 is removed from the support portion main body 32. By pulling out, the wiring / piping material support portion 31 can be removed from the wire 21. Therefore, even if the wiring / piping material support portion 31 exists at a location that matches the connecting piece 63 of the erection member 60, the wire intermediate portion C can be held by removing the wiring / piping material support portion 31 from the wire 21. Can do.

  (10) The wiring / piping material laying path K of the four-story building is formed by the two laying tools 20. Compared with the case where the wiring / piping material laying path K extending over the fourth floor is formed by one laying tool, the one laying tool 20 is lightened and is easy to carry. Moreover, the burden in the site | part which suspends each cloth fixture 20 can be reduced, and the load at the time of the fabric fixture 20 shaking can also be reduced.

  (11) The cloth fixture 20 has a ladder shape including two wires 21 and wiring / pipe material support portions 31 spanned between the two wires 21. The two wires 21 can support the wiring / piping material support portion 31 in a stable state, and the wiring / piping material support portion 31 can support the cable P in a stable state.

  (12) The dimension in the longitudinal direction of the erection member 60 that functions as the wire holding member is longer than the dimension in the short direction of the through hole forming member 50. For this reason, the attachment holes 61 a on both sides in the longitudinal direction of the erection member 60 can be made to face the pedestals 55 disposed on both sides in the short direction of the through-hole forming member 50. As a result, the erection member 60 can be arranged in a state in which the erection member 60 blocks a part of the through hole 11 defined by the through hole forming member 50.

Each embodiment may be changed as follows.
As shown in FIG. 13, the wire holding member 90 may have a longer dimension in the longitudinal direction than the erection member 60 of the embodiment.
