The material is supported by the wiring / piping material support so as to form a gap between the material and the inner surface of the through hole, and is fixed to the building wall and a holding part that holds the wiring / piping material support. A fixing member having, is fixed to the building wall. The wiring / piping material support is held by the holding portion of the fixing member at a position separated from the building wall. In this embodiment, a resin or steel sleeve-shaped conduit is exemplified as the wiring / piping material. Further, the building wall is a fireproof partition wall, and an example thereof is one in which a filler such as a heat-resistant putty or a heat-expandable fireproof member is filled between the inner surface of the through hole and the outer surface of the wiring / piping material. Hereinafter, each component will be described in detail.

First, as shown in FIG. 2, the wiring / piping material support (hereinafter, simply referred to as “support”) 10 constituting the wiring / piping material fixing structure 1 shown in FIG. 1 is a C-shaped steel 20 and wiring / piping. It is composed of a material support member (hereinafter, simply referred to as “support member”) 30. The C-shaped steel 20 is made of a long steel body having a substantially C-shaped constant cross section, and the bottom wall 21, a pair of side walls 22 and 22 standing upright from the bottom wall 21, and the tip sides of the side walls 22 face each other. It has a pair of lip portions 23, 23 folded back toward the side wall 22 and an opening 24 formed between the pair of lip portions 23, 23.

The support member 30 is composed of a duct clip, and as shown in FIG. 2, a pair of holding pieces 31 and 31 having the same size and the same shape are arranged symmetrically and assembled to face each other using screws. Each holding piece 31 is formed by bending a steel plate, a flange 33 bent vertically upward is formed at the upper end of the curved portion 32 bent in a curved shape, and an insertion hole through which a screw is inserted is formed in the central portion of the flange 33. 34 is provided. Further, a leg plate portion 35 made of a vertical flat plate is formed on the lower side of the curved portion 32, and a substantially U-shape into which the lip portion 23 of the C-shaped steel 20 can be fitted into both end edges in the width direction of the lower portion of the leg plate portion 35. A notch space 36 is formed, and a locking portion 37 is formed below the notch space 36 so as to project horizontally outward and engage with the lip portion 23 of the C-shaped steel 20. The curved portion 32 has substantially the same radius of curvature as the radius of the conduit 60, and is formed so that the entire inner surface abuts along the outer surface of the conduit 60 when the conduit 60 is sandwiched.

In the support member 30, the pair of holding pieces 31, 31 are inserted into the opening 24 of the C-shaped steel 20, and the electric conduit 60 is inserted between the pair of holding pieces 31, 31 and inserted into the insertion holes 34 of both flanges 33.

It is provided. In addition, the fixing member 40 is provided with a projecting piece 44 at the tip edge portion of the long piece, that is, the tip end portion of the holding portion 42, which is bent downward at a right angle and protrudes on the opposite side of the fixing portion 41. .. The fixing member 40 also corresponds to the C-shaped steel fixing member according to the claim.

More specifically, the fixing portion 41 is formed in a plate shape having an abutting surface that abuts on the building wall 70, and is fixed to the pillar 72 of the building wall 70 on the upper side at the central portion in the width direction of the short piece. A screw hole 45 through which a screw is inserted is provided, and an anchor hole 46 for driving an anchor into the building wall 70 when the building wall 70 is made of a concrete wall is provided on the lower side. When the building wall 70 is a wooden board or gypsum board, if the screw inserted through the screw hole 45 of the fixing portion 41 is screwed only to the building wall 70, the wall material may collapse and the fixing member 40 may be securely attached to the building wall. Since there is a possibility that it cannot be fixed to 70, the screw is screwed to the pillar 72 erected on the building wall 70. When the building wall 70 is made of a concrete wall, there are no restrictions such as fixing it to a pillar.

The holding portion 42 has an insertion portion 47 made of a substantially inverted T-shaped plate-shaped projecting piece to be inserted into the opening 24 of the C-shaped steel 20, and the insertion portion 47 punches a part of the long piece by a press. It is formed by bending vertically downward, and is provided as a pair separated by a predetermined length in the width direction of a long piece. Both sides of the lower half of the insertion portion 47 form a suspension portion 47a that is locked to the lip portion 23 of the C-shaped steel 20 and suspends the lip portion 23. Further, the width of the upper half of the insertion portion 47, which is slightly narrower than the suspension portion 47a, is formed to be slightly smaller than the opening 24 of the C-shaped steel 20, whereby the suspension portion 47a is formed of the C-shaped steel. It is prevented that the opening 24 of 20 is displaced in the width direction and comes off from the lip portion 23 and falls off.

The above-mentioned projecting piece 44 that bends downward at a right angle from the tip of the holding portion 42 and protrudes is provided with a long hole 44a that is long in the vertical direction at the center in the width direction. A screw is inserted into the elongated hole 44a after the fixing member 40 is attached to the C-shaped steel 20, and the screw is screwed to the side wall 22 of the C-shaped steel so that the fixing member 40 is along the longitudinal direction of the C-shaped steel 20. The projecting piece 44 and the elongated hole 44a constitute the movement restricting means according to the claim. Conversely, in the insertion portion 47 of the holding portion 42 of the fixing member 40, the suspending portion 47a is a lip portion until the screw is inserted into the elongated hole 44a and screwed into the side wall 22 of the C-shaped steel 20. It can be moved along the longitudinal direction of the C-shaped steel 20 in a state of being locked to the 23, and the projecting piece 44 and the elongated hole 44a can be said to be means for adjusting the position of the fixing member 40 with respect to the C-shaped steel 20. The movement restricting means is not limited to the one in which the screw is attached to the elongated hole 44a and the side wall 22 of the C-shaped steel 20, and the movement may be restricted by other means.

Next, a method of supporting the conduit 60 pulled out from the through hole 71 of the building wall 70 and arranging it at the wall penetrating portion by the wiring / piping material fixing structure 1 of the present embodiment configured as described above. This will be described with reference to FIGS. 4 to 10.
Here, as shown in FIG. 4, a pillar 72 is erected between the double walls which are the building walls 70, and the building wall 70 has a hole diameter larger than that of the conduit 60 and the conduit 60 penetrates therethrough. A through hole 71 is provided.

First, as shown in FIG. 5, the C-shaped steel 20 is installed around the through hole 71 of the building wall 70 by using the fixing member 40. At that time, the wall surface 73 is positioned in the horizontal direction of the pillar 72 into which the screw inserted into the screw hole 45 of the fixing portion 41 is screwed by drawing a scribe line in the vertical direction on the wall surface 73 of the building wall 70 in advance.

At the same time, when the C-shaped steel 20 is mainly fixed to the wall surface 73 as shown in FIG. 7 (a), the left and right fixing portions 41 so that the C-shaped steel 20 horizontally crosses the through hole 71 at the position of the chord. The position of the screw hole 45 in the height direction is displayed by inserting a horizontal ruled line or the like. When the two orthogonal display lines are displayed on the wall surface 73 in this way, the intersection of these display lines becomes the installation point of the screw hole 45 of the fixing portion 41. Here, in the through hole 71, the chords crossed by the C-shaped steel 20 are the outer surface of the conduit 60 and the through hole when the conduit 60 is placed on the upper end of the C-shaped steel 20 as shown in FIG. 7 (a). The position and height are set so that the gap S with the inner surface of the 71 is uniform over the entire circumference of the conduit 60, and the distance between the upper end of the C-shaped steel 20 and the lowest point of the through hole 71 is the gap S. It will be the same length.

On the other hand, at both ends in the longitudinal direction of the C-shaped steel 20, the insertion portions 47 of the holding portions 42 of the two fixing members 40 are inserted into the opening 24 from the longitudinal side ends of the C-shaped steel 20, and the protrusions of the fixing members 40 are projected. A screw is inserted into the elongated hole 44a of the piece 44, the tip of the screw is brought into contact with the side wall 22 of the C-shaped steel 20, and the fixing member 40 is temporarily held by the C-shaped steel 20.

Therefore, in this temporary holding state, as shown in FIG. 5, a screw is inserted at the installation point of the screw hole 45 of the fixing portion 41 to penetrate the wall surface 73, and further, the center of the pillar 72 on the back surface side of the wall surface 73 in the width direction. The pair of left and right fixing members 40, 40 are fixed to the wall surface 73 by screwing to the position. Then, when the left and right fixing members 40 are positioned so as to be evenly arranged at both ends of the C-shaped steel 20, screws are inserted into the elongated holes 44a of the projecting pieces 44 of the fixing member 40 and screwed onto the side wall 22 of the C-shaped steel 20. And finally tighten. In this state, the C-shaped steel 20 and the building wall 70 are separated by the length of the wall separating portion 43 of the fixing member 40. Further, the fixing portion 41 of the fixing member 40 is located on the anti-bottom wall 21 side of the opening 24 of the C-shaped steel 20 held by the holding portion 42, that is, above the opening 24.

Next, the conduit 60 is passed through the through hole 71, pulled out to the wall surface, and placed on the C-shaped steel 20. The state in which the conduit 60 is placed on the C-shaped steel 20 is shown in FIGS. 6 and 7.

After the conduit 60 is placed on the C-shaped steel 20, as shown in FIGS. 8 and 9, the conduit 60 is fixed to the C-shaped steel 20 by using the support member 30. To do so, the leg plate portions 35, 35 of the pair of holding pieces 31, 31 of the support member 30 are inserted into the opening 24 of the C-shaped steel 20 in a state parallel to the lip portion 23, and then rotated in the horizontal direction. The lip portion 23 is fitted into the notch space 36 by changing the direction by 90 degrees, and the locking portion 37 is locked to the lip portion 23. Then, the conduit 60 is sandwiched between the pair of sandwiching pieces 31, 31 and the C-shaped steel 20 by inserting screws into the insertion holes 34, 34 of the flanges 33, 33 of the pair of sandwiching pieces 31, 31 and tightening them. And fix it.

After the electric wire tube 60 is supported and fixed by the support tool 10 and the fixing member 40 in this way, as shown in FIG. 10, a heat-resistant putty and thermal expansion are provided in the gap S between the inner surface of the through hole 71 and the outer surface of the electric wire tube 60. A filler 80 such as a fireproof member is filled to close the gap S. The filler 80 is inserted into the caulking tube directly or using a tool such as a caulking gun. At this time, the filler 80 is filled in the gap S of the through hole 71 from above from the viewpoint of workability. On the other hand, with respect to the lower portion of the through hole 71 in the back side portion and the back side portion of the C-shaped steel 20, the C-shaped steel 20 and the building wall 70 are separated by the length of the wall separating portion 43 of the fixing member 40. Since the filler 80 is separated by a size that can be inserted into the gap S in the through hole 71, the filling material 80 is filled in the gap S of the through hole 71 by using the space T of the separated portion. can do. If it is necessary to fill the gap S from below depending on the location where the through hole 71 is installed, the entire gap S of the through hole 71 is used only by using the space T between the C-shaped steel 20 and the building wall 70. Can also be filled. In any case, the filler 80 is inserted by utilizing at least the space T between the C-shaped steel 20 and the building wall 70.

In the above procedure, in FIGS. 6 and 7, the conduit 60 is pulled out to the wall surface by penetrating the through hole 71 of the building wall 70 before installing the C-shaped steel 20 and the fixing member 40 on the building wall 70. , It may be placed on the C-shaped steel 20, fixed to the C-shaped steel 20 using the support member 30, and then the C-shaped steel 20 may be installed on the building wall 70 via the fixing member 40.
