DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe / wire fixing embedded member used for fixing a pipe or wiring to a ceiling, a wall, a pillar, a floor, or the like, and a pipe / wire fixing device using the same. Things.

[0002]

2. Description of the Related Art Conventionally, sheath pipes used for indoor pipes, for example, a sheath header method of a water supply / hot water supply piping system,
When a flexible conduit used for wiring is fixed to a concrete slab or the like of a building, a saddle 1 as shown in FIG. 24 is used. The saddle 1 fixes the mounting pieces 1b on both sides to a concrete slab with concrete nails 5 in a state where the pipe 3 is accommodated in the concave portion 1a. FIG. 25 shows a state in which the pipe 3 is fixed to the ceiling slab 7 by the saddle 1.

In addition, a method using a pipe holder 9 as shown in FIG. 26 is also known. In this case, first, the pipe holder 9 is fixed to the ceiling slab 7 or the like with the concrete nail 5, and then the pipe 3 is fixed by pushing the pipe 3 into the pipe holder 9.

However, when a saddle 1 as shown in FIG. 24 is used, the saddle 1 is attached to the pipe 3 while the pipe 3 is pressed against the slab surface by hand, and the saddle 1 is dropped. Saddle 1 so that it does not shift
Is necessary to drive the concrete nail 5 with an electric drill driver or the like while holding down with the hand. In particular, when the pipe is fixed to the ceiling slab, the worker must climb the stepladder and perform the above-mentioned work while looking up at the ceiling, which is extremely inconvenient and dangerous.

Also, when using the pipe holder 9 as shown in FIG. 26, it is necessary to perform a troublesome operation of driving a concrete nail with an electric drill driver or the like while holding the pipe holder 9 by hand. Especially in the case of ceiling piping, there is a problem similar to the case of using a saddle. In addition, piping holder 9
Is used, a gap G corresponding to the thickness of the pipe holder 9 is formed between the slab 7 and the pipe 3, so that the stability of the pipe is poor. In the case of a water supply / hot water supply pipe, when a water hammer occurs, the pipe 3 hits the surface of the slab 7 to generate noise.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a pipe / wire fixing embedded member which can easily fix a pipe / wire to a concrete slab or the like and can sufficiently reduce a gap between the concrete slab or the like and the pipe / wire. And a pipe and wiring fixture using the same.

The embedding member is used as follows in combination with a holding member for holding piping and wiring. First, a portion to be attached to the mold is fixed to a predetermined position (a position where the embedding member is to be installed) of the concrete mold.
After that, concrete is poured into the form and solidified, and then the form is removed. Then, the embedded member is embedded in the concrete with the lower end opened. In this state, the embedding member has no risk of falling out of the concrete because the flange portion has cut into the concrete.

On the other hand, the holding member has a holder for holding piping and wiring, and a support shaft protruding from the holder and inserted into the shaft locking portion of the embedded member. Therefore, as the work of fixing the piping and wiring, after holding the piping and wiring in the holder of the holding member, the supporting shaft is inserted into the shaft locking portion of the embedded member, or the supporting shaft of the holding member is connected to the shaft of the embedded member. After inserting it into the lock,
It is only necessary to hold the wiring, and the piping and wiring can be fixed very easily. Further, since the embedded member has a lower space below the shaft locking portion, the projecting portion from the surface of the pipe / wiring around the support shaft of the holder is housed in the lower space, so that the piping / wiring is provided. It is possible to eliminate the gap between the concrete and the concrete surface or to make it sufficiently small.
