The present invention relates to a concrete structure, and in more detail, when using an adhesive bolt when remodeling and repairing an old building, an adhesive that can firmly install a reinforcement plate on a concrete wall or ceiling surface in which cracks are generated is used. The concrete structure does not.

Concrete structures are affected by durability, load capacity, and structural life due to various reasons such as aging, disasters, design and construction defects, change of use over time, and structural damages require front or partial reinforcement measures. Therefore, repair and reinforcement of such a structure increases the life of the structure and becomes an essential process for ensuring safety.

One of the reinforcing methods of concrete structures, the steel plate bonding method is a method of surface-treating the structure to be reinforced (concrete structure) and then installing the steel plate using anchor and welding, then sealing and injecting epoxy resin to bond.

However, in the conventional steel plate bonding method, a lot of dust is generated in the process of working with a grinder to treat the surface of the adhesion surface, and it is difficult to process dust in precision equipment or basement, and it is difficult to treat the wall (existing sphere) and steel plate (steel plate). ) In the process of constructing by injecting adhesives such as epoxy, the workability is decreased due to the use of high-hazardous materials.In the process of fixing the wall and steel plate using epoxy, the steel sheet is separated from the wall due to expansion force and impact. In addition, the epoxy injection process could not be visually confirmed and the quality thereof could not be confirmed. In particular, the work process to seal the edge of the steel sheet for epoxy injection, the work process to prevent the leakage of epoxy by covering the spiral part of the anchor bolt using a sealing cap as a separate part, and the inlet for epoxy injection Due to the large volume of the work process and the sealing cap itself, the overall aesthetics are not good as well as unnecessary work processes that must be repaired individually.

As such, there is an inefficient and inefficient economic problem such as waste of manpower and time due to the cumbersome and unnecessary work process, increase of construction cost due to the increase of the construction period and the number of parts to be used. In particular, when the epoxy is filled in the inside, especially when the steel plate (reinforcement plate) is adhesively fixed to the concrete structure using epoxy, each reinforcement plate is installed at predetermined intervals, so that the cracks are separated through the spaces between the reinforcement plates. There is a problem that occurs.

The present invention is to solve such a conventional problem, it is an object of the present invention to provide a concrete structure that can achieve a more easy operation and economic effect by reducing the number of parts used together with a shortening of the work process.

1a to 3b is a view showing a concrete structure (slab, beam) without using the adhesive to which the reinforcing structure of the present invention is applied.

As shown in Figure 1a to 1b, the concrete structure 100 without using the adhesive is a slab (110a) is a wall, the filler plate 120, reinforcement plate 130 and anchor bolts that are fastening means for fastening them 142 and the tightening nut 144 is configured.

The anchor bolt 142 is inserted into the bolt insertion holes 112 formed in a predetermined depth on the outer surface of the slab (110a). The filling plate 120 and the reinforcing plate 130 are formed by drilling the first and second through holes 122 and 132 corresponding to the bolt insertion holes 112, respectively, and the first and second through holes 122 and 132, respectively. A portion of the anchor bolt 142 is exposed to the outside through them. The tightening nut 144 is fastened to the exposed anchor bolt.

After the anchor bolt 142 is installed on the slab 110a, the filling plate 120 and the reinforcing plate 130 are sequentially stacked, and in this state, a tightening nut 144 is attached to the anchor bolt 142. As the fastening plate 120 and the reinforcing plate 130 are fastened, the fastening plate 120 and the reinforcing plate 130 are fixed in close contact with the slab 110a. Here, the reinforcing plate 130 may be selectively used, such as carbon fiber epoxy panel, aramid fiber epoxy panel, glass fiber epoxy panel, FRP epoxy panel.

In addition, the filling plate 120 is a steel-filled filling plate 120a integrated by reinforcing and inserting a steel plate 126a having a plurality of punching holes formed inside a mat 124 made of a rubber material (neoprene) as shown in FIG. 4A. It can be made of). As shown in Figure 4b, the filler plate 120 may be made of a steel wire-filled filler plate (120b) integrated by reinforcing the steel wires (126b) arranged in a grid shape in the mat 124 made of a rubber material. . Alternatively, as shown in Figure 4c, the filler plate 120 may be made of a fiber-filled filler plate 120c integrated by reinforcing the lattice-shaped steel fibers 126c into the mat 124 made of a rubber material.

As such, according to the present invention, since the reinforcing plate is fixed to the wall tightly and firmly through the filling plate, no additional adhesive filling is required between the reinforcing plate and the wall. In other words, the filler plate serves as an existing adhesive (filler between the reinforcing plate and the wall).
