The stud T temporary fixing step), and thereafter, the wall plate S is constructed.

The through hole reinforcing step is a step of mounting a fixing bracket around the through hole S2 to reinforce the periphery of the through hole S2. At this time, it is necessary to securely connect the fixing bracket and the wall plate S and integrate them. In the present application, a fixing member composed of a main body cover 1 and a connecting metal member 2 described later is connected and fixed using a fastening member 8 made of an IT bolt for a gypsum board.

The connecting step is a step of connecting and fixing the fixture and the pipe P. By this step, the pipe P is connected to the hollow wall plate S via the fixing bracket.

Next, the fixing bracket of the present invention comprises a main body cover 1 and a connecting fitting 2, and fixes a pipe P to the connecting fitting 2 via a support 3 (FIGS. 2 and 3). reference).

The main body cover 1 and the connecting fitting 2 are fixed to a fastening tool 8.
Is connected and fixed to the wall plate S. At this time, the fastener 8
Uses IT bolts for gypsum board. The fastening tool 8 made of the IT bolt for the gypsum board is a fastener in which the tip of the IT bolt is bent and locked inside the hollow wall by inserting the IT bolt into the fastening through hole S3 penetrating the wall plate S. (See FIG. 3). The main body cover 1 is fixed to the wall S by overlapping the wall S around the through hole S2 from above the through hole S2.

On the other hand, the connecting metal fitting 2 is fixed from the lower part of the through hole S2 to the wall S by overlapping the wall plate S around the through hole S2 and the main body cover 1, and fixed to the wall S. A support 3 for supporting the pipe P is provided. The connection fitting 2 in the illustrated example is formed by bending and extending the support 2B from the lower end of the connection 2 and has a clip mounting hole 2A for connecting the support 3 at the tip of the support 2B (FIG. 2).
Then, the lower end of the clip-shaped support 3 that is sandwiched and fixed around the pipe P is supported by the mounting hole 2A so as to be supported.
The pipe P is supported between the supports 3 (see FIG. 3).

The runner fixing fitting 4 is a fitting for temporarily fixing the pipe P using the runner R when the runner R is located near the pipe P penetrating the wall plate S. The metal fitting of the illustrated example is provided with a metal fitting having a U-shaped cross section that overlaps the opening R1 of the runner R, and a through hole 4A provided on a side surface of the metal fitting. Then, a through bolt 4B is inserted into and connected to the through hole 4A of the runner fixing bracket 4. The runner fixing bracket 4 has a clip mounting hole 4C for connecting a support 5 composed of a clip that is clamped and fixed around the pipe P.
(See FIG. 4).

The stud fixing fitting 6 is a fitting for temporarily fixing the pipe P using the stud T. This stud fixing bracket 6
It is a metal fitting to be attached to the lip portion T1 of the stud T of the lip channel steel, and includes a plate nut 6A attached inside the lip T1 and a mounting screw 6B attached from the surface of the stud fixing metal 6.
The stud fixing bracket 6 is fixed, and a clip mounting hole 6C for connecting a support 7 made of a clip is provided on the plate surface of the stud fixing bracket 6 (see FIG. 5).

[0017]

According to the present invention, the above-mentioned configuration achieves the original object.

That is, the periphery of the through hole S2 of each wall plate S made of gypsum board forming the hollow wall is reinforced by superposing the body cover 1 and the connecting metal fitting 2 on top of each other, and the tip of the bolt is formed by the hollow wall. Since the fixing fitting is fixedly fastened to the surface of each wall plate S by the gypsum board fastening tool 8 which is bent and locked inside, the strength of the hollow wall can be reliably increased. In addition, the load of the pipe P is dispersed and supported via the fixing member in which the body cover 1 and the connecting member 2 are integrated, and the support portion 2B and the supporting member 3 extending from the lower end of the fixing member.
The pipe can be supported without using an insert, an anchor, or the like as in the related art.
