Description of the Related Art In general, a concrete structure is composed of reinforcing bars arranged in a grid, providing a formwork, casting concrete, constructing a concrete frame, and decorating with a paint or tiles as necessary. Or arrange them. Of course, such a concrete skeleton is designed and constructed so that it can sufficiently bear the load from the beginning, but there are cases in which a load far exceeding expectations is applied. In addition, the structure naturally deteriorates with age, and for example, the skeleton deteriorates due to cracks, corrosion of reinforcing steel due to water leakage, and the like.

割れ等が起こり難くなるという利点がある。Therefore, a reinforcing material such as a sheet material made of carbon fiber, glass fiber, synthetic resin, metal mesh or the like or a steel plate such as a thin iron plate is adhered to the surface of the concrete frame with an adhesive to reinforce the concrete frame. Means (hereinafter, referred to as an adhesion reinforcing method) are used. As one example of such a bonding reinforcement method, the surface of an existing concrete skeleton is polished, a cured resin is applied to secure the bonding strength, and a carbon fiber sheet is bonded as a reinforcing material from above by applying a hardening resin thereon. Then, there is a method in which a resin is further impregnated thereon. According to such a method, there is an advantage that the rigidity of the concrete skeleton is increased because the reinforcing material and the concrete skeleton are integrated, and cracks and the like due to a load are less likely to occur.

しなくなるという問題点があった。However, in the above-mentioned method for adhering and reinforcing a concrete frame, the bonding surface is peeled off by the moisture generated from the concrete and the reinforcing material is lifted up, and the integrity of the concrete frame and the reinforcing material is lost. There was a problem that it would not function sufficiently as reinforcement of the concrete frame.

ら根本的な問題を解決するものではない。[0005] Particularly, in the case of a concrete skeleton for constructing a peripheral wall such as a floor slab of a bridge or a tunnel, the above problem is remarkable because a large amount of water is generated not only from the concrete but also from the ground. As a countermeasure against such peeling, a measure of injecting an adhesive into a raised portion is also taken, but it does not solve a fundamental problem at all because the same portion or a different portion is peeled.

とは明らかである。On the other hand, the above-mentioned sticking and reinforcing method is composed of many steps as described above, the work is complicated, and the material cost is relatively high. In particular, when a pattern or the like is painted on the surface of the concrete frame, if the sticking reinforcement method is applied, the pattern must be painted again. Therefore, it is clear that it is most preferable if the concrete skeleton can be reinforced without using such a bonding reinforcement method.

On the other hand, in the case of concrete skeletons that do not have the adhesive reinforcement method, the method is used to reinforce the concrete skeleton relatively easily and at low cost without using a reinforcing material, and the construction method. It is an object to provide an anchor pin to be used.

れば、より効果的である。The concrete frame 26 is reinforced by providing a large number of anchor pin bodies 1 in a direction substantially perpendicular to the surface of the concrete frame 26. That is, as shown in FIG.
In the case of the concrete frame 26, when the load G is applied, the concrete layers A and B are displaced from each other and the concrete frame is easily bent, but in the concrete frame 26 in which the reinforcing method using the anchor pin according to the present invention is performed. Since the concrete layers C and D are sewn by the anchor pin main body 1 as shown in FIG.
A frictional force acts between the layers, thereby preventing the layers from shifting. Therefore, the rigidity of the concrete skeleton 26 is increased. In particular, it is more effective if the anchor pin main body 1 is fitted and fixed to the position crossing the reinforcing bar inside the concrete frame as described above.
