Environment-friendly fireproof door capable of controlling expansion of sealing piece

Abstract

The invention discloses an environment-friendly fireproof door capable of controlling expansion of a sealing piece. The environment-friendly fireproof door comprises a door frame, a fire extinguishingunit and a sealing piece expansion unit; the left side of the rear side face of the door frame is rotationally connected with the left side of the rear side face of a door plate through hinges, the upper surface of the door frame is fixedly connected with the middle of the lower surface of a supporting plate, and an annular groove is formed in the middle of the inner side face of the door frame;the fire extinguishing unit comprises a water pipe, a water tank, a water pump, a main water pipe and six spray heads, the interior of the water tank is hollow, the lower surface of the water tank isfixedly connected with the right side of the upper surface of the supporting plate, the side face of the main water pipe is fixedly connected with the front side of the lower surface of the supportingplate, and the number of the spray heads is six. According to the environment-friendly fireproof door capable of controlling expansion of the sealing piece, the front side of the fireproof door can be automatically subjected to fire spraying and extinguishment when a fire occurs, fire at a door opening is prevented from grilling the door plate all the time, the sealing strip can be tightly attached to the door plate when the fire occurs, and smoke leakage is prevented.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to an environment-friendly fire door that can control the expansion of a sealing member. Background technique [0002] A fire door is a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with certain fire resistance located in fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke diffusion. To prevent the spread of the fire and ensure the evacuation of personnel, the existing fire doors can only prevent the spread of the fire through passive fire protection. People’s escape provides a favorable time, and the existing fire doors use inlaid sealing strips, which will contact the door panels during daily use, causing the sealing strips to...

It is a fire-resistant partition with certain fire resistance located in fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke diffusion. To prevent the spread of the fire and ensure the evacuation of personnel, the existing fire doors can only prevent the spread of the fire through passive fire protection. People’s escape provides a favorable time, and the existing fire doors use inlaid sealing strips, which will contact the door panels during daily use, causing the sealing strips to wear and tear, and cannot perform a good seal in the event of a fire function, resulting in toxic fumes and passing through the fire door to affect people's life and health
