Description of the Related Art In general, concrete structures are constructed by reinforcing steel bars in a grid, providing a formwork, casting concrete, constructing a concrete frame, and decorating with paint or tiles as necessary. Or arrange them. Of course, such a concrete skeleton is designed and constructed so as to sufficiently withstand the load from the beginning, but a load much more than expected may be applied in some cases. 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, a metal mesh net or the like or a steel plate such as a thin iron plate is adhered to the surface of the concrete body with an adhesive to reinforce the concrete body. Means (hereinafter, referred to as an adhesion reinforcing method) are used. As an example of such a bonding reinforcement method, the surface of an existing concrete skeleton is polished, a hardening resin is applied to secure the bonding strength, and a carbon fiber sheet is bonded thereon as a reinforcing material via an adhesive. 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.

A method of reinforcing a concrete body to which the adhesive reinforcement method has been applied will be described. First, as shown in FIG. 4, the anchor pin main body 1 is drilled from the top of the reinforcing material 25 to a concrete frame 26 to which a reinforcing material 25 such as a carbon fiber sheet material is adhered by an adhesive such as epoxy resin. A hole 27 having a depth such that the screw portion 8 protrudes to the outer surface side of the concrete frame 26 when the anchor pin main body 1 is fitted is provided.

The holes 27 into which the crotch and the anchor pin main body 1 are to be fitted are provided at approximately equal intervals at approximately 16 locations per square meter. The length, thickness, etc., of the concrete frame 26 to be constructed may be changed as appropriate.

The protrusions 3, 3 of 1 are pushed and expanded, and the tip 1b side of the anchor pin main body 1 bites into the concrete skeleton 26 and is fixed.

An adhesive such as epoxy resin is applied to one side 11a of the flange portion 13 of the base member 13 and the threaded portion 15 of the pin fitting portion 14 of the seat body 11 is screwed to the thread portion 8 of the anchor pin main body 1 to strengthen the reinforcing member. 25 on the surface
13 is crimped on one side 11a. At this time, the grooves 12, 12 formed on the one surface 11a serve as an adhesive pool.

強材25による補強の実効を図ることができる。According to the concrete body reinforcing method described above, moisture generated from the concrete body 26 is transferred from the hole 10 formed in the anchor pin main body 1 to the rear end 1c of the anchor pin main body 1 through the through hollow portion 1a of the anchor pin main body 1. It has an action of escaping from the opening 2 to the outside of the concrete body, that is, diverging as a water outlet. Accordingly, the bonding surface of the reinforcing member 25 is not separated and lifted by moisture, and the integrity of the concrete skeleton 26 and the reinforcing member 25 is maintained, and the reinforcement by the reinforcing member 25 can be effectively performed. .

る。Further, since the reinforcing material 25 adhered to the concrete frame 26 is pressed against the concrete frame 26 by the flange 13 of the seat 11 screwed to the anchor pin main body 1, it is not caused by moisture. In addition, there is an advantage that peeling of the reinforcing material 25 caused by natural deterioration of the adhesive can be prevented.

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 easily bends. 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.

Also, the size and number of the holes can be appropriately changed in design. The point is that at least one hole 10 should be formed in the peripheral wall of the anchor pin main body 1 in order to release moisture generated from the inside of the concrete frame 26.

Of course, the seat body 11 in which the covering body 18 is integrally formed may be used. In addition, it is also possible to use an anchor pin in which the anchor pin main body 1 and the seat body 11 are integrally formed.

In particular, if the seat body 11 is formed in a hexagonal shape or the like, when the seat body 11 is fixed to the anchor pin main body 1, it can be tightened with a wrench or the like. There is an advantage that can be.
