Flame-retardant fireproof door

Abstract

The invention belongs to the technical field of fireproof doors, and particularly relates to a flame-retardant fireproof door. The fireproof door comprises a door body and a door frame; a fireproof cavity is arranged inside the door body, a sliding plate is installed in the middle of the fireproof cavity, the top end of the sliding plate is connected with a traction plate, the top end of the innerwall of the fireproof cavity is connected with a positioning plate, the top end of the traction plate is symmetrically connected with connecting rods, the outer ends of the connecting rods are connected with baffle plates, a water outlet groove is formed in the door body on one sides of the baffle plates, a water flow groove and a water pipe I are arranged in the door frame at the top end of thedoor body, and the upper end surface of the door body is connected with a water pipe II. According to the fireproof door, through the arrangement that the fireproof cavity and a sliding mechanism arearranged inside the door body, the door body can spray water on a fire site through the water outlet groove, the flame retardancy and fireproof effects of the fireproof door can be achieved more effectively, and at the same time, the fireproof door is lighter and more convenient when in use, and can extinguish fire on escaping personnel whose clothes are on fire, so that the use effect of the flame-retardant fireproof door is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of fire doors, in particular to a flame-retardant fire door. 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. It can prevent the spread of fire within a certain period of time and ensure the evacuation of people. Most of the steel fire door fillers used at present are silicic acid fiber, rock wool, etc. Their disadvantages are low strength, toxicity, and great harm to human body, so they are not suitable for industrial production. [0003] There are also some technical solutions on fire doors in the existing technology, s...

AI Technical Summary

Problems solved by technology

[0004] Although the fire doors in this scheme can achieve a certain flame-retardant and fire-proof effect by filling yellow sand, dry powder or water, due to the large number of filling materials and heavy volume, the use and transportation of the fire doors become cumbersome and inconvenient. The fire door can only make the internal materials flow out when it is damaged, which affects the timely and efficient work of the fire door, and because the fireproof material filled inside the fire door is limited, the fire door has a certain degree of continuous flame resistance and fire protection.
