Description

[Detailed explanation of the invention] Conventional spacer hardware is manufactured entirely from metal, so when the tip of the protrusion is exposed on the concrete surface, as shown in Figure 7, the rust on the tip of the protrusion is also exposed. It was extremely unseemly.

In addition, conventional spacer hardware is usually manufactured by integrally molding a single metal plate, and therefore the protruding portion is also shaped like a U-shaped groove (Fig. 8), and only the protruding portion is thickened for the purpose of reinforcement. Because it is impossible to do so, the U-shaped groove-like protrusion is often deformed due to the pressure applied by pouring concrete (Figure 9).
There was a drawback that the objective was not fully achieved.

The present invention is intended to eliminate the above-mentioned drawbacks, and will be explained below with reference to the drawings.

1 is a groove-shaped support part, 2 is a groove-shaped protrusion part from the front.
One side of the support part 1 is integrally bent at the center at a right angle to the support part 1 so as to protrude. 3 is a protrusion provided on the inner wall of the other side of the support part 1 on the side opposite to the protrusion 2; 4 is a round-shaped synthetic resin having the same shape as the protrusion 2 or made of a material having the same effect and fitted to the tip of the protrusion 2; It is a reinforcement body.

5 is the reinforcing bar supported by the bearing part 1, 6 is the reinforcing body 4
This groove 6 is formed on one side of the protrusion 2.
The reinforcing body 4 is fixed to the protrusion 2 by fitting into the tip of the protrusion 2. 7 is concrete surface, 8 is concrete surface 7
The exposed tip of the protrusion 2 is shown.

In addition, in order to prevent the reinforcing body 4 from falling off the protruding part 2, the groove part 6 is made into a thick tapered cross section as shown in FIG. A reinforcing body 4 may also be fitted.

The present invention is as described above, and by fitting the groove 6 formed on one surface of the reinforcing body 4 made of synthetic resin or the same material to the tip of the protruding part 2, the protruding part 2 is reinforced. Since the body 4 is fixed, there is no risk that the tip of the protruding part 2 will be exposed to the concrete surface, and even if the reinforcing body 4 is exposed to the outside, it will not rust unlike metal ones.

Further, the reinforcing body 4 has the effect of eliminating the drawback that the protrusion 2 is opened or deformed due to pressurization caused by pouring concrete.

Furthermore, the reinforcement body 4 has a front surface having the same shape as the protrusion 2.
Since the reinforcing body 4 is fixed by fitting the groove 6 to the tip of the protruding part 2, the reinforcing body 4 as a whole has a relatively small shape, but prevents the protruding part 2 from being exposed on the concrete surface. It contributes to the action, is efficient considering the size of the material, and
The front face shape of the reinforcing body 4 improves stability and aesthetics compared to the U-shaped one, and furthermore, the protrusion 2 has a feature that the cover (height) can be adjusted by machining.

Furthermore, since the front shape of the protruding portion 2 is round-shaped, the spacer has high stability against falling.
