Abstract

PURPOSE: To make it difficult for pipes to come out of connection collars by extending engagement claws from the semi-arch pipe close-fit parts of a frame body. CONSTITUTION: A pair of semi-arch pipe close-fit parts of a pipe supporting device 21 are butted and overlapped to form a pipe stand 20. Also the connecting end part of a pipe 31 is close-fitted supportedly in the pipe support holes of a pair of pipe supporting devices 21 to collect the connecting end parts of multiple pipes 31 on the pipe stand 20. Then a pair of the connecting end parts of the collected pipes 31 are inserted from both ends of a connection collar 32 and connected, and the engagement claw 24 of each pipe supporting device 21 is engaged with an engaged step part 32A which is provided at both end parts of the connection collar 32. By this, the pipe stand 20 is prevented from coming out of the connection collar 32. In addition, an engaged projection formed on the inner periphery of the pipe supporting device 21 of the pipe stand 20 is engaged with the corrugated form of the collected pipes 31. By this, the pipes 31 are prevented from coming out of the pipe stand 20. Thus the pipes 31 do not come out of the connection collar 32.
