<p><P>PROBLEM TO BE SOLVED: To provide a branch pipe mounting device capable of surely preventing opening of a flange fastening portion of a double-split branch pipe mounting device and preventing water leakage, even when an independent socket-shaped branch pipe is inserted in and mounted on an opening portion of the branch pipe mounting device. <P>SOLUTION: This branch pipe mounting device has a branch pipe mounting device main body 3 formed into at least two pieces, capable of being mounted on an existing pipe K, and having a branch portion S opened in the direction different from the direction of the existing pipe K in an approximately horizontal face same as the existing pipe K to form a three-way opening portion, and a branch pipe 8 mounted on the branch portion S of the branch pipe mounting device main body 3. When the external force is acted in the direction to take out the branch pipe 8, a projection St and a recessed portion 8b are engaged with each other, thus fitting faces of the branch pipe mounting device main body 3 split into two pieces, are pressed in the fastening direction, and the slipping-out of the branch pipe 8 is prevented. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
