Embodiment Construction

[0011] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0012] Such as figure 1 The self-service fire door shown includes: a base 1, a metal casing 2, a fire wall body, a piston member and a closing plug 5. The metal casing 2 is arranged above the base 1 , and inside the metal casing 2 are provided two mutually separated firewall bodies, a piston part and a closing plug 5 . Between the above two firewall bodies is a material cavity 3, and the bottom end 3 of the material cavity is provided with a material outlet. The piston part includes a connecting rod 401 and a closing plate 402 and a piston 403 arranged at its two ends. The base is formed with a gas chamber 6 with a vertical piston hole for injecting high-pressure gas. The front side of the base 1 is formed with a slope The discharge channel is provided with a closed glass plate 7 at the outlet of the discharge channel, the connecting ro...

Abstract

The invention discloses a self-help fireproof door which comprises a base, a metal shell arranged above the base, two mutually-separated fireproof walls arranged inside the metal shell, a piston member and a sealing plug. A material cavity is formed between the fireproof walls, a discharging port is arranged at the bottom end of the material cavity, the piston member comprises a connecting rod, a sealing plate and a piston, the sealing plate and the piston are arranged at two ends of the piston member, a gas cavity with a vertical piston hole and for injection of high-pressure gas is formed in the base, a discharging passage with a slope is formed on the front side of the base, a sealing glass plate is arranged at a port of the discharging passage, the piston is arranged in the gas cavity to seal the same, the gas cavity is provided with a gas outgoing passage leading to the rear-side outside of the base, and the sealing plug plugs a passage port of the gas outgoing passage. The self-help fireproof door has the advantages that a fire extinguishing function is provided, so that fireproofing time is increased, and sufficient time is provided for people to escape.

Description

technical field [0001] The invention relates to a fireproof building material, in particular to a self-service fireproof door. Background technique [0002] Fire doors are divided into fireproof wooden doors, fireproof steel doors and fireproof stainless steel doors. Usually, fire doors are used in openings of firewalls, entrances and exits of stairwells, evacuation walkways, openings of pipe wells and other parts, which play an important role in fire separation and reduction of fire losses. Gain time for people to escape from the fire and prevent the fire from spreading. The fire performance of fire doors is one of the concerns of people. The existing metal door has single function and poor fire performance. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the object of the present invention is to provide a self-service fire door with a longer fire time. [0004] In order to achieve the above object, the present invention adopts ...
