Water-cooling firefighting door structure

Abstract

The invention discloses a water-cooling firefighting door structure which structurally comprises a reinforcing threshold, mounting pull pieces, flag-type hinges, a door closer, a door leaf, compositefireproof glass, a fireproof lock, a seam covering plate, a water-cooling device and a door frame. The reinforcing threshold and the door frame are welded, and the composite fireproof glass is connected on the door leaf in an embedded manner. When in use, the water-cooling firefighting door structure is embedded in a wall through the mounting pull pieces to enable the door frame to be fixed on thewall, the door leaf is in hinged connection with the door frame through the flag-type hinges, and the door closer is connected with the door leaf and the door frame at the same time to enable the door leaf to be closed automatically; when a protection door is in a fire and generates high temperature, a pressure device generates pressure to enable condensed water to flow into a condensed water inlet pipe from a liquid storage tank, to flow in a cooling pipe through U-shaped water pipes to adsorb high temperature on the door leaf and to flow into the liquid storage tank for cooling through a backflow pipe for recirculation. The water-cooling firefighting door structure can effectively resist fire behaviors even in a fire at high temperature, can prolong rescue time and plays an effective role in protecting residents.

Description

technical field [0001] The invention relates to a water-cooled fire door structure, which belongs to the technical field of fire doors. Background technique [0002] An accredited laboratory designated by the Ministry of Economic Affairs, according to the new national standard for fire doors GB_12955-2008 implemented on January 1, 2009, the fire door fire resistance test method has passed the test, and has obtained the verification registration certificate and authorized logo issued by the Standard Inspection Bureau of the Ministry of Economic Affairs , called fire doors, the fire doors defined by the US NFPA and IBC codes are "any combination of fire doors, door studs, hardware and other accessories that jointly provide a certain degree of fire protection for the opening." It is a door that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. It is a fire partition with certain fire resistance in fire compart...
