Currently used sprinkler head connecting sockets have a structure such that a flexible pipe for supplying fire water is connected to a head, and a groove is formed to fix the head to an M-bar on a ceiling material with a clip. In most cases, the disassembly of the head is impossible because the head rotates together with the socket when the head is rotated to be replaced. It has been confirmed that the fixing strength of a tightening bolt is weak, and the tightening of the tightening bolt has become loose after inspecting the fixing state of the sockets because both the clip and the socket are circular. It has been found that regulations on the fixing state of the head are insufficient after confirming fire safety standards relating to the installation of sprinklers. The purpose of the present invention is to compensate for the insufficient regulations by improving the performance of facilities. |
