Joined.
In the case where one of the plate-like members is damaged, for example, by reducing the tightening force by the tightening means, thereby releasing the frictional force between the joining plate and the adhesive plate, The body alone can be removed relatively easily and replaced with a new plate.
[0008]
A feature of the invention according to claim 2 is that the surface of the adhesive plate on the joining plate side is formed as a friction joining surface by blasting.
[0009]
According to the characteristic configuration of the second aspect of the present invention, since the surface of the adhesive plate on the joining plate side is formed as a friction joining surface by blasting, the frictional force between each adhesive plate and the joining plate becomes stronger. As a result, the two plate-like members can be more firmly joined, and nevertheless, as described above, only one of the plate-like members can be relatively easily removed and replaced with a new plate-like member.
[0010]
A feature of the invention according to claim 3 is that the friction joining surface has a friction coefficient of 0.35 or more.
[0011]
According to the characteristic configuration of the third aspect of the present invention, since the frictional joint surface of the adhesive plate has a friction coefficient of 0.35 or more, the frictional force between each adhesive plate and the joint plate is reliably maintained at a predetermined value or more. Thus, the two plate-like bodies can be more firmly joined.
[0012]
A feature of the invention according to claim 4 is that the two plate-like bodies are plate glass, the joining plate and the bonding plate are metal plates, and each of the metal bonding plate and each plate glass is impregnated into the sheet. Where it is bonded by the adhesive.
[0013]
According to the characteristic configuration of the fourth aspect of the present invention, since both plate-like bodies are plate glass and the joining plate and the adhesive plate are metal plates, relatively brittle plate glasses are securely joined by the interposition of the metal joining plate. And the frictional force between the metal bonding plate and the metal bonding plate can be expected as desired, and the bonding force between the metal bonding plate and the sheet glass impregnated into the sheet. Adhesion with an adhesive can be expected as a result, and as a result, the two glass sheets can be firmly joined to each other even though the both glass sheets are glass sheets.
[0014]
