ることによる補強工法である。This plate joining method is roughly divided into an injection method and a crimping method. The former is a reinforcing method by making a gap between a structure and a plate and injecting an adhesive.
The latter is a reinforcing construction method in which an adhesive material is applied to the plate body and pressure-bonded to the structure.

り解決される。[Means for Solving the Problems] The above-mentioned problem is that when a plate is bonded to a structure, a block and a heater wire formed by impregnating a mat-like material with a thermosetting resin in advance are provided on the structure and the plate. It is solved by adhering the structure and the plate body by arranging the plate body between them and pressing the plate body and energizing the heater wire.

A plate pressure bonding method can be provided. Furthermore, in addition to these means, a complete plate body crimping method can be provided by arranging air vent pipes in a dispersed manner over the entire bonding surface.

空気や余分な樹脂は外部に排出される。The present invention has the following actions. The thermosetting resin impregnated in the mat-like material is once melted and cured by energizing the heater wire. Therefore, the pressed plate body is bonded and integrated with the structure. Also,
Since the spring structure is placed in the fastener and the plate is pressed,
It responds to the filling of resin in voids and the volume change of resin due to the unevenness of the adhesive surface. Furthermore, since the air vent pipes are dispersedly arranged on the entire adhesive surface, the air and excess resin staying on the adhesive surface are discharged to the outside.

As shown, it is fastened by a known method, for example, a fastener 3 such as a bolt. If necessary, the periphery of the plate body 2 is easily sealed with an elastic sealing material 9. In the following, including this embodiment, a steel plate was used as the plate body, but it goes without saying that a new material such as carbon may be used.

The plate body 2 is fastened. A spring 6 having a restoring force against compression is interposed between the plate body 2 and the nut 3b of the anchor bolt 3a. 7 is a washer. The spring 6 is pressed when the nut 3b is tightened, and continues to press the plate body 2 due to the force of returning to the original, even if the volume change occurs in the process of melting and hardening of the thermosetting resin, they follow these. The plate body 2 acts so as to fit into the bonding surface of the structure 5.
