BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a device for attaching a reinforcing material or a rod according to the present invention will be described with reference to an embodiment shown in the drawings. The device for attaching a reinforcing material or a rod according to the present invention is configured to include a fixture 1, a holder 2, and a reinforcing material or a rod 3 that is locked to the holder 2.

Here, the fixture 1 is provided with a long nut-shaped embedding member 4 having a female screw portion inside, and a bolt-shaped fixing member 5 screwed into the female screw portion of the embedding member 4.

The embedding member 4 of the fixture 1 is embedded in the base material 6 made of concrete or the like at a right angle to the base material 6 and fixed in the base material 6. Specifically, the tip of the embedding member 4 is driven by using a hammer or the like to embed it in the base material 6.

Next, as understood from FIGS. 1 and 2, the holder 2 is folded in two in a U-shaped cross section and has a pair of adjacent side pieces 7, 7.

On the upper side of the pair of side pieces 7, there is formed a notch 9 extending in the horizontal direction from the base 8 side of the half-folded portion toward the tip end in the opposite direction.

As can be seen from FIGS. 1 and 2, the reinforcing member or the bar member 3 such as a mesh bar or a reinforcing bar arranged at a predetermined distance from the base material 6 such as concrete is the holder. It is accommodated in the two notches 9.

After that, the bolt-shaped fixing member 5 is screwed into the female screw portion of the embedding member 4, and is pressed by the bolt head 10 so as to narrow the gap between the cut portions 9, and thus the reinforcing material or the bar materials 3 and 3 are attached. The base material 6 is sandwiched and locked at a predetermined distance.

Here, in the present invention, the material of the fixture 1 and the holder 2 is not limited in any way, and may be steel, plastic, hard rubber or wood.

As for the shape of the holder 2, as shown in FIGS. 3 to 6, the two-folded portion may be curved in a U shape, may be bent in a triangular shape, or may be in a quadrangular shape. It may be bent or trapezoidal.

Further, the notch 9 is mainly formed by making a notch from the side of the base portion 8 that is folded in half and extending to the tip side, but it is also possible to make a notch from the tip side conversely. .

Next, a holder 2 according to another embodiment will be described.

The holder 2 in the above-mentioned embodiment is formed by a plate-like member, and for example, a rectangular plate-like member is folded in half from the intermediate position in the longitudinal direction, and then a cut portion 9 is formed to complete the holder. However, the present invention is not limited to this, and the holder 2 may be formed of a so-called long rod-shaped member.

That is, for example, a metal rod member is bent into a frame shape as shown in FIGS.
May be formed.

Although the basic form is constructed as shown in FIGS. 8 to 10, the upper part may be reinforced to form the structure shown in FIGS. 11 to 13 for the purpose of reinforcing the foot side of the holder 2. Alternatively, it may be formed by bending as shown in FIGS.

Further, the cross-sectional shape of the rod-shaped member may be round rod-shaped, triangular rod-shaped or square rod-shaped isotropic rod-shaped. In addition, FIG. 17 shows another embodiment of the fixture 1.

In this embodiment, the fixture 1 is the fixing member 5
And the embedding member 4 are integrally formed.

As will be understood from FIG. 17, the fixing method of the fixing tool 1 to the base material 6 in this embodiment is such that the bolt head 10 of the fixing member 5 is hit with a hitting tool such as a hammer, and the like. The embedding member 4 is embedded and fixed in the base material 6, and the upper and lower side pieces 7, 7 of the notch 9 of the side piece 7 are pressed by the bolt head 10.
Therefore, the reinforcing material or the bar material 3 can be held by being sandwiched in the cut portion 9.

With this type of fixture 1, however, the fixture 1 is embedded in the base material 6 by simply striking the bolt head 10 of the fixture 5 like a so-called nail member.
Although they can be fixed, it becomes relatively difficult to adjust the rate of pressing the side piece 7 with the bolt head 5.

However, in the case of the fixture 1 according to the first embodiment, the bolt-shaped fixing member 5 is of a screw type, so it takes time to screw it in.
It becomes easy to adjust the ratio of pressing down.

Although the reinforcing member or the bar member is attached by the attaching device according to the present invention at a plurality of positions on the base material, the screw-in type fixing device 1 and the fixing member 5 and the embedding member 4 are attached. The integrally formed fixing tool 1 can be used in a mixed manner. For example, the screw-type fixing tool 1 is used in an important place, and the fixing member 5 and the embedding member are used in other places where quick mounting is required. It is possible to properly use the fixture 1 in which 4 and 4 are integrally formed.

As described above, the present invention has the above constitution.

With the reinforcing material or rod attaching device according to the present invention, the rod-shaped reinforcing material or the rod material such as the mesh reinforcing bar or the reinforcing bar can be accurately and surely installed, and the rod-shaped reinforcing material or the rod can be installed. Easy to attach the material, shortening the construction period and reducing the cost, special work such as welding is unnecessary, and there is no cross-section loss due to melting of the rod-shaped reinforcing material or the rod that occurs during welding. Highly reliable and has an excellent effect.
