Air-pipe floor penetrating fireproof structure
The invention discloses an air-pipe floor penetrating fireproof structure. The air-pipe floor penetrating fireproof structure comprises a horizontally-arranged floor and an air pipe which is vertically arranged and penetrates through the floor. The air-pipe floor penetrating fireproof structure is characterized in that a fireproof structure body is arranged at the portion, close to the floor, of the interior of the air pipe and comprises a horizontally-arranged short connecting sheet welded to the inner wall of the air pipe, a hot melting sheet connected with the short connecting sheet and a metal gate valve connected with the hot melting sheet and located below the short connecting sheet. Due to the metal gate valve connected with the hot melting sheet, when fire behaviors spread along the air pipe and the hot melting sheet is burnt, the hot melting sheet is molten; at the moment, the metal gate valve rotates around the hinged point accordingly, the whole inner diameter of the air pipe is completely blocked accordingly, and the fire behaviors are prevented from upwards spreading.
