シール材に接続されている。Reference numeral 1 is an elastic hollow core material made of synthetic rubber with upper and lower layers, which is bonded to the body in layers, and an outer shell material 2 made of butyl-based, silicone-based, etc. having adhesive properties is layered around the outer periphery of the multi-layered hollow core material constructed in this way. A pressure fluid injection vibe 3 and an air release vibe 4 are connected to each of the elastic hollow core members 1, respectively. (See Fig. 1) A rectangular frame is assembled using the sealing material A constructed as described above, and at the corners of the rectangular frame, the outer surface I
The triangular corner sealing material A' is formed on an inclined surface where the cross-sectional area of the sealing material increases as A' reaches the tip, and the free end surface IA'' is formed on an inclined surface of 45 degrees. It is connected to the seal material of the section.

て同開口部Ｂ′をシールする。(See Fig. 4) Fig. 3 shows an embodiment in which the sealing frame constructed as described above is used to waterproof the opening of a concrete structure. When a solidifying pressurized fluid such as gourat material is injected from the pressurized fluid injecting vibrator 3, the elastic hollow core material 1 is expanded by the fluid, and the outer shell material 2 of the concentric material 1 is pressurized. It deforms and presses against the opening B' of the concrete structure B and the sash C to seal the opening B'.
