Branch pipe joint of synthetic resin pipe with rib

Abstract

Abstract PURPOSE:To connect a branch pipe in a watertight condition by providing a penetration hole to a synthetic resin pipe with ribs, cutting off the ribs along the periphery of the penetration hole, installing a packing, and fastening an installing plate thereover. CONSTITUTION:A penetration hole 4 is engraved to a synthetic resin pipe 1 with ribs in order to connect a branch pipe 3, the ribs 2 are cut off along the periphery of the penetration hole 4, and a ringformed packing 5 is installed there. And at the peripheral surface of the synthetic resin pipe 1 with ribs at the position of the penetration hole 4, an installing plate 6 furnishing a hole 7 and a cylindrical flange 8 at the center is abutted, and fastened by bands 9. As a result, the packing is not moved and the installing plate is not removed from the synthetic resin pipe with ribs after the branch pipe is connected, and the branch pipe can be contacted closely. And the outer periphery of the branch pipe is contacted closely with the packing and the cylindrical flange in the installing plate, and connected in a watertight condition.
