Title: Sealing method of connecting part and sealing means
Inventor: SCHMID RENE P
IPC: F16J15/14
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To simply and quickly seal a connection part with a connecting piece or connecting part seal tube by inserting or pressing a connecting part seal tube into a connecting part, and applying pressure to the walls deciding the boundary of the connecting part by the wall of the tube so as to generate pressure in the tube. SOLUTION: A tube main body 2 of annular section or flat section made of flexible plastics such as rubber is constructed so as to change only in the sectional shape pressure when a tube 1 is applied with inner pressure, and to show a circular section when applied with high pressure. When the tube 1 with flat sectional forms of both side is inserted into a connecting part 6 between the two parts of a stone building 7 defining walls 8 as a boundary, the tube can be naturally held by compression from both sides of the walls 8 and frictional contact of the walls 8 with the tube 1. Hereby, by applying air pressure or water pressure to the tube 1 so as to compress the tube main body 2, the sealing effect can be guaranteed by expansion of the tube main body 2, even when the connecting part 6 afterward spreads.
