2. Description of the Related Art Conventionally, indoor pipes (for example, pods used in pod pipe construction methods of water supply / hot water supply pipe systems,
When fixing a flexible conduit used for wiring to a concrete slab of a building or the like, a saddle 1 as shown in FIG. 12 is used. This saddle 1 has a concave portion 1a
The mounting pieces 1b on both sides are fixed to a concrete slab by concrete nails 5 in a state in which the pipe 3 is accommodated. FIG. 13 shows a pipe 3 with a saddle 1 on a ceiling slab 7.
Shows a state in which is fixed.

In addition, a method using a pipe holder 9 as shown in FIG. 14 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.

[0004]

However, when a saddle 1 as shown in FIG. 12 is used, the saddle 1 is mounted on 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.

[0005] In addition, when the pipe holder 9 as shown in Fig. 14 is used, 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.

An object of the present invention is to provide a pipe and wiring fixing embedded member which can easily fix pipes and wiring to a concrete slab and the like, and a pipe and wiring fixing tool using the same.

[0007]

According to the present invention, there is provided an embedding member for fixing piping and wiring, comprising: a cap-shaped member; a shaft locking portion provided integrally with the cap-shaped member inside the cap-shaped member; A flange portion provided outside the mold member above the lower end edge of the cap mold member and integrally provided with the cap mold member, and a concrete formwork provided to project outward from the lower end edge of the cap mold member The shaft engaging portion is formed so as to allow insertion of the shaft into the cap-type member but resist pulling out of the shaft. A space is provided between the top of the member and the shaft to allow insertion of the shaft.

The embedding member is used as follows in combination with a holding member for holding piping and wiring. First, the mounting portion of the embedding member is fixed to a predetermined position of the concrete form (a position where the embedding member is to be installed) with a nail or the like. 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 surface exposed. 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.

[0010]

Embodiments of the present invention will be described below in detail with reference to the drawings. [Embodiment 1] FIGS. 1 to 4 show a first embodiment of a pipe fixing device according to the present invention. This piping fixture is composed of a combination of an embedding member 11 as shown in FIG. 1 and a piping holding member 13 as shown in FIG.

The embedding member 11 has a hollow cap-shaped member 15 composed of a peripheral wall and a ceiling plate. The lower edge of the cap member 15 is integrated with the flat plate portion 17 made of a steel plate by welding, bonding, or other means. Of the flat plate portion 17,
At a position corresponding to the inner central portion of the cap member 15,
As shown in FIGS. 1D and 1E, a screw locking portion 19 is formed. The screw locking portion 19 is formed by forming a screw insertion hole 21 in the flat plate portion 17 and forming slits in four directions from the screw insertion hole 21 to form four elastic claw pieces 23. The elastic claw piece 23 is bent slightly upward. The inner diameter of the screw insertion hole 21 is set slightly smaller than the outer diameter of the groove bottom of a screw (described later) inserted therethrough. A space 25 is provided between the screw locking portion 19 and the ceiling plate of the cap-shaped member 15 so that a screw described later can be inserted.

The flat plate portion 17 outside the cap-shaped member 15
The steel plate continuous from the flat plate portion 17 is bent upward and further outwardly on two parallel sides of the flange portion 2.
7 are formed. The flange 27 is located above the lower edge of the cap member 15. A nail hole 29 is formed near another pair of two parallel sides of the flat plate portion 17, and the periphery of the nail hole 29 is a portion to be attached to the concrete formwork.

On the other hand, as shown in FIG. 2, the holding member 13 includes a holder 31 for holding the pipe, and this holder 31.
And a screw 33 projecting therefrom. Holder 3
1 is a substantially semicircular saddle member 35 as shown in FIG.
A band 37 as shown in FIG. The saddle-shaped member 35 has a gate-shaped protrusion 39 for accommodating the head of the screw 33 at the center, and a band through hole 41 is formed in both legs of the gate-shaped protrusion 39. Further, a band pressing piece 43 is formed on the outer periphery of the saddle member 35. The band 37 is marketed under the trade name of Insulok,
When the other end is inserted into the buckle part 45 formed on one end side, the knurls 47 are caught by the claws in the buckle part 45 and cannot be pulled out. Holder 31
Is to pass such a band 37 through the saddle-shaped member 35 as shown in FIG.

Next, a method of using the piping fixture configured as described above will be described with reference to FIGS. First, FIG.
As shown in FIG.
9 is fixed at a predetermined position by a nail 51. Thereafter, the concrete 53 is poured into the formwork 49 and solidified. When pouring concrete, the flat plate portion 17 is
, The space 25 in the cap member 15
Concrete does not penetrate into the building. Concrete 5
After the mold 3 is solidified, the mold 49 is removed, as shown in FIG. 6 (FIG. 6 is a sectional view taken along line AA in FIG. 5). That is,
The embedding member 11 is exposed to the concrete 53 by exposing the lower surface.
(In this case, the ceiling slab).
In this state, since the flange portion 27 bites into the concrete 53, there is no possibility that the embedded member 11 comes off from the concrete 53. Thus, the embedding member 11 is fixed at a predetermined position of the concrete 53.

Next, after the pipe 3 is held by the holder 31 of the holding member 13, the screw 33 is inserted into the screw locking portion 19 of the embedding member 11. At this time, the elastic claw piece 23 is elastically deformed upward to allow the screw 33 to be inserted. When the screw 33 is pushed in to the end, the result is as shown in FIG. In this state, since the elastic claw 23 bites into the valley of the screw 33, the screw 33 does not come out even if a downward load is applied to the holding member 13. As described above, the pipe can be fixed by a very simple operation.

The embedded member main bodies 11 are installed at appropriate intervals along the piping route. If the piping route is not determined at the stage of assembling the concrete formwork, an extra embedding member 11 may be installed on the expected route, and a material that matches the actual route may be selected and used. Further, when the holding member 13 is mistakenly attached to the embedded member 11 deviating from the route, or when the piping route is changed, the holding member 13
If the holding member 13 is rotated in a direction to loosen the screw 33 after removing the pipe 3 from the, the holding member 13 can be removed from the embedded member 11. Therefore, it is possible to flexibly respond to a work error or a route change.

[Embodiment 2] FIG. 8 shows another embodiment of the embedding member according to the present invention. The embedding member 11 is different from that of FIG. 1 in that an arrowhead-shaped projection 55 is formed instead of the nail hole 29 of FIG. That is, the elastic claw pieces 23 are used. The other parts are the same as those in FIG. 1, and the same parts are denoted by the same reference numerals. The protrusion 55 can be formed by cutting and raising a part of the flat plate portion 17 toward the lower surface side. If such projections 55 are formed, nails are not required when the embedded member 11 is fixed to the concrete formwork.

[Embodiment 3] FIGS. 9A and 9B show another embodiment of the support shaft of the holding member. In the first embodiment, the screw 33 is used as the support shaft.
Uses a shaft 59 having a cap-shaped protrusion 57 at the tip as a support shaft. In this case, the cap-shaped projection 57 is caught by the elastic claw piece of the shaft locking portion and cannot be pulled out. The cap-shaped protrusion 57 may be formed in a plurality of stages. FIG.
(B) uses a soft rod 61 such as a plastic rod or an aluminum rod as a support shaft. Embedded member 1
Since the elastic claw piece 1 is generally made of a steel plate, if the soft bar 61 as described above is used, the elastic claw piece 23 becomes
It can be made into a state where it cannot be pulled out by biting into 1.

[Embodiment 4] FIG. 10 shows another embodiment of the holding member. This holding member 13 is a pipe holder 31
A band 67 having a plurality of hooks 63 at one end at appropriate intervals and a hook hole 65 at the other end is used, and a screw 33 is attached to an intermediate portion of the band 67. The holding member 13 wraps the band 67 around the pipe and attaches any of the hooks 63 to the hook hook holes 6.
5 to hold the pipe.

[Embodiment 5] FIG. 11 shows still another embodiment of the holding member. The holding member 13 uses, as the pipe holder 31, a pipe holder 69 having a circumference equal to or more than half the circumference of the pipe, and attaching a screw 33 to a portal projection 39 provided in the middle of the pipe holder 69. It is.

In the above embodiment, the case where the piping is fixed has been described. However, the present invention is similarly applicable to the case where the wiring is fixed.

[0022]

As described above, according to the present invention, piping and wiring can be fixed by a simple operation of pushing the support shaft of the holding member into the embedded member main body without using a concrete nail or the like. Therefore, the piping and wiring work, particularly the piping and wiring work to the ceiling slab, can be performed safely and quickly.
