The invention discloses a smoke-baffling escaping fireproof door. A door frame is connected with a door leaf through a hinge; a fireproof lock is located under a handle; fireproof glue is arranged at the bottom of the door leaf; a smoke-proof rock wool layer is arranged at the center in the door leaf; cylindrical cavities are uniformly arranged in the middle of the smoke-proof rock wool layer; metal frameworks are arranged on the front and back sides of the smoke-proof rock wool layer; heat-insulating plates are respectively arranged on the metal frameworks on the front and back sides; first transparent glue is arranged between a first raw glass sheet and a second raw glass sheet; and second transparent glue is arranged between the second raw glass sheet and a third raw glass sheet. According to the smoke-baffling escaping fireproof door, the first transparent glue is arranged between the first raw glass sheet and the second raw glass sheet, the second transparent glue is arranged between the second raw glass sheet and the third raw glass sheet, and the first transparent glue and the second transparent glue can be quickly hardened at high temperature so as to form a nontransparent smoke-proof plate, so that the flame spreading can be prevented while the conduction of high temperature toward the side unexposed to the fire can be prevented.
Description
technical field [0001] The invention relates to the technical field of fire doors, in particular to a smoke-proof escape fire door. Background technique [0002] Statistics show that most of the casualties caused by fires are caused by smoke inhalation, and the suffocation deaths caused by this account for 1 / 2 to 2 / 3 of the total number of deaths. Even the people who were burned to death were mostly suffocated by the smoke and lost the ability to escape. It can be seen that minimizing the loss caused by smoke is an important part of escaping from a fire. The smell of smoke caused the poisonous gas to spread rapidly, causing a large number of casualties to those who had no time to escape. Contents of the invention [0003] The purpose of the present invention is to provide a smoke-proof escape fire door to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following tec...
