に行われず、接着が必ずしも完全とはいえない。However, the use of an adhesive block such as a frozen block or a solidified block is different from the conventional method in which an extra adhesive is placed on the plate and pressed against the structure. Therefore, the air staying on the adhesive surface, for example, the air staying in the void due to the unsteady state is not sufficiently discharged, and the adhesive is not sufficiently filled in the void, so that the adhesive cannot be said to be perfect.

解決する。The above object is to provide an air vent pipe on the bonding surface of a structure so that an air vent hole at one end faces the bonding surface of the structure, and the other end is outside the crimping portion between the structure and the plate. In order to solve the problem, the air is accumulated on the entire bonding surface so as to be located at the position, and the air staying on the bonding surface is discharged from the air vent hole of the air vent pipe to the outside of the crimped portion by pressing from the plate.
