Abstract

PURPOSE: To make air supply and exhaust easier by providing an opening for atmospheric communicating pipe at a height higher than at least one connecting point among a combined air vent pipe and a vertical drain pipe on the pipe wall for vertical vent pipe with the bottom end connected to the vertical drain pipe. CONSTITUTION: At a rising portion of a lateral drain branch pipe 2' on each story, extended top vent pipe 4 communicating to the atmosphere is connected. Also, the opening portion 3' as boundary, the upper end portion of a vertical vent pipe 3 comprising an upper vertical vent pipe 3a and a lower vertical vent pipe is connected to the pipe 4 and also communicated respectively to each branch pipe 2 through a cross type joint. Moreover, at the opening portion 3', a vent pipe 11 for opening to the atmosphere is connected through the cross type joint. And air intake and exhaust are performed through the pipe 4 and the opening to the atmosphere through the pipe 11 is performed also on a middle story thereby improving air circulation inside the pipe 3.
