DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing rod support for supporting and fixing a conduit or the like provided in a reinforced concrete building, and in which a conduit or the like disposed between reinforcing bars is brought into direct contact with the reinforcing bar. The present invention relates to a pipe support for a reinforcing bar that is supported and fixed without being supported.

[0002]

2. Description of the Related Art Conventionally, in a reinforced concrete slab piping, a flexible conduit made of a synthetic resin is often used.
In order to support the conduit tube or the like on a reinforcing bar, a clip is mainly used. This clip intersects the side surface of the conduit and supports and fixes the rebar and the conduit in contact with each other (see FIG. 4).

Further, as a device for protecting a conduit between reinforcing bars, there is a tube protection spacer described in Japanese Utility Model Publication No. 4-38008. The spacer particularly prevents the conduit between the reinforcing bars from being crushed when the worker moves on the reinforcing bars. For this reason, a conduit or the like is inserted and supported between a pair of opposed side plates, and the upper end of the side plate is configured as a reinforcing bar mounting surface.

[0004]

However, in the clip used conventionally, since the conduit and the like are supported in contact with the reinforcing steel, the conduit and the like come into contact when concrete is poured. Concrete did not rotate sufficiently around the reinforcing steel bar, and the slab strength was reduced.

[0005] In addition, the above-mentioned pipe protection spacer for protecting conduits and the like can protect conduits and the like,
Since the spacer itself comes into direct contact with the reinforcing bar, the surroundings of the reinforcing bar with which the spacer is in contact are not filled with concrete, and sufficient strength cannot be obtained.

Accordingly, the present invention has been made to solve the above-mentioned problem, and is intended to provide a pipe such as an electric conduit provided between reinforcing bars by providing a sufficient gap between the reinforcing bars and the pipes. It is an object of the present invention to provide a reinforcing-bar tube support that can be supported by a supporter and that is extremely easy to support and attach.

[0007]

Means for Solving the Problems In order to achieve the above object, a first means of the present invention is to provide a composite member which is forcibly fitted to and sandwiched on the outer surface of a pipe Q arranged between reinforcing bars P. A fitting support 1 made of resin is provided. On the other hand, the connecting wire 2 wound around the reinforcing bars P is formed of an iron wire. Then, the connection line 2 is attached to the fitting support 1 such that the ends of the connection line 2 extend in opposite directions. The purpose of the present invention is to provide a gap between the reinforcing bars P and the pipe Q between the reinforcing bars P and the pipe Q to support the pipe Q by providing the gap.

[0008] Further, the second means is formed by projecting a connecting projection 1A on the side surface of the fitting support 1. An insertion hole 1B for inserting the connection wire 2 is formed in the connection protrusion 1A. The fact that the connecting wire 2 is inserted into the connecting hole 1B and attached is used as means for solving the problem.

[0009]

Embodiments of the present invention will be described below.

The rebar tube support of the present invention comprises a fitting support 1 for sandwiching and supporting a tube Q, and a connecting line 2 for supporting and connecting the tube Q between the rebars P with a gap therebetween. (See FIG. 1).

The tube Q is mainly a conduit such as a flexible conduit made of synthetic resin, but may be another tube disposed between the reinforcing bars P.

The fitting support 1 clamps and supports the tube Q by forcibly fitting the outer surface of the tube Q.
Therefore, as the material of the fitting support 1, an elastically deformable material such as a synthetic resin or a metal is suitable. In the illustrated example, the fitting support 1 made of synthetic resin is used to form a substantially C-shaped side surface. (See FIG. 2).

The connecting wire 2 supports the pipe Q by wrapping around the reinforcing bars P and providing a gap between the reinforcing bars P and the pipe Q to fill the concrete. This connecting line 2 is
In particular, by using an iron wire similar to the iron wire connecting the reinforcing bars P, the iron wire becomes familiar with the cast concrete. At this time, the connection line 2 is attached to the fitting support 1 such that the ends of the connection line 2 extend in opposite directions. In the illustrated example, a connecting protrusion 1A is formed on the side surface of the fitting support 1 so as to protrude therefrom, and two insertion holes 1B for inserting the connecting wires 2 are formed in the connecting protrusion 1A. Then, one connecting line 2 is alternately inserted into the insertion hole 1B, and a central portion of the connecting line 2 is fixed to the insertion hole 1B. By attaching the connecting wire 2 in this way,
The work of attaching the connecting wire 2 to the fitting support 1 becomes easy, and the fitting support 1 can be reliably supported by the connecting wire 2.

Next, in using the present invention, for example,
In order to support the tubular body Q between the reinforcing bars P of the upper and lower muscles of the slab muscle, the fitting support 1 is disposed at a half of the distance between the upper and lower muscles of the slab muscle. In this state, the connecting wires 2 are wound around and fixed to the upper and lower muscles (see FIG. 3). Tube Q
It is possible to freely select whether the fitting support 1 is fixed and then supported by the fitting support 1 or the fitting support 1 is attached to the reinforcing bar P while supporting the tube Q. It can be used properly depending on the situation of plumbing work.

[0015]

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

That is, according to the first aspect, it is possible to provide a sufficient gap between the reinforcing bar and the pipes to support the pipe. As a result, it was possible to sufficiently cast concrete also around the reinforcing bar P supporting the pipe Q, and it was possible to prevent a decrease in slab strength.

According to the first and second aspects of the present invention, the connecting wire 2 can be easily mounted simply by winding the connecting wire 2 around the reinforcing bar P.
Can be carried out extremely easily. Moreover, the fitting support 1 and the tube Q can be reliably supported by the connecting wire 2.

As described above, according to the present invention, it is possible to support pipes such as electric conduits arranged between reinforcing bars with a sufficient gap between the reinforcing bars and the pipes for filling concrete. In addition, various industrially useful effects such as extremely easy support mounting work can be achieved.
