Further, by coating various primers instead of the backup material B, it is possible to prevent the sealing material C from adhering at three points.

The sealing material C is a silicone type (reaction curing type, moisture curing type), modified silicone type (reaction curing type),
Fire resistance of polysulfide type (reaction curing type), polyurethane type (reaction curing type, moisture curing type), SBR type (dry curing type), acrylic type (dry curing type), etc., or foams thereof or inorganic type It is formed from one or more kinds of the sealing material C having the above-mentioned, and has at least elasticity and waterproofness. The sticking and forming are self-adhesive, or integrally formed through an adhesive or by utilizing elastic deformation. Of course, it is also possible to improve the fire resistance by mixing a flame-retardant material into these fillers.

The extruded material D such as EPDM is as shown in FIG. 5, and generally, for example, EPDM, polyvinyl chloride type, chloroprene type, chlorosulfonated polyethylene type, ethylene propylene type, asphalt impregnated polyurethane type, etc. With elasticity, or polybutene type,
One of non-elastic type such as polypropylene type, butyl type and rubber asphalt type is used. In particular, when weather resistance and heat resistance are required to form the portion exposed to the outside as shown in FIG. 2 and FIG. 4, the weather resistance such as EPDM, heat resistance, ozone resistance, chemical resistance, etc. Use the one that is superior. The recess D ₁ is provided to accommodate the head of the fixture β and is formed by the head of the fixture β so that the extruded material D such as EPDM is not deformed.

The dry wall material E is, for example, metal siding, double-sided metal steel plate panel, various ceramic siding, P
