发明名称 PIPE JOINT FOR DRAINAGE AND VENTILATION
摘要 PROBLEM TO BE SOLVED: To provide a pipe joint for drainage and ventilation, which enables an insertion portion to be surely inserted into a vent pipe without reference to a construction error of the length of the protrusion of the vent pipe, the degree of the horizontality of the cut surface of the vent pipe, etc., and which enables it to be easily checked whether or not the insertion portion is surely inserted into a vent hole. SOLUTION: This pipe joint comprises a joint pipe body 11, an insertion body 12 which is inserted from an upper opening of the joint pipe body 11, and a tubular cover body 13 which is provided at the upper end of the joint pipe body 11 in such a manner as to cover the upper end and to which an extension pipe 3 is to be connected. The insertion body 12 comprises a flange portion 12a which is installed on the upper end surface of the joint pipe body 11, and the tubular transparent insertion portion 12b which is provided on the undersurface of the flange portion 12a and inserted into the vent pipe 2 inserted into the joint pipe body 11. Thus, the insertion portion can be surely inserted into the vent pipe without reference to the construction error of the length of the protrusion of the vent pipe, the degree of the horizontality of the cut surface of the upper end of the vent pipe, etc., and it can be easily checked whether or not the insertion portion is surely inserted into the vent hole.
