Composite fireproof door and manufacturing process

Abstract

The composite fireproof door comprises a door frame and a fireproof door main body, transparent glass is installed on the fireproof door main body, a fireproof lock is arranged on the fireproof door main body, a buffer structure is arranged on the fireproof door main body, and an identification structure is fixedly installed on the fireproof door main body. And an insect prevention structure is fixedly mounted at the lower end of the fireproof door main body. According to the composite fireproof door and the manufacturing process, the composite fireproof door belongs to the field of fireproof doors, a buffering structure can achieve the buffering effect, the fireproof door is prevented from directly impacting a sealing strip when closed, an elastic frame is used for buffering, the buffering effect is excellent, the service life is long, a guide frame is used for guiding the elastic frame, the use smoothness of the elastic frame is guaranteed, and the service life is prolonged. The guide frame can be detached and can be conveniently detached for replacement, through the arranged identification structure, the signboard is not prone to falling off after being installed, the structure is simple, operation is convenient and fast, and through the arranged detachable insect prevention structure, insect prevention can be effectively conducted.

Description

technical field [0001] The invention relates to the field of fire doors, in particular to a composite fire door and a manufacturing process. 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. Composite fire doors usually refer to the structure of steel and wood composite molding, which has the characteristics of good fire prevention effect and light weight; in the existing composite fire doors, when the fire door is closed, the door panel directly hits the airtight strip, which is easy to b...

AI Technical Summary

Problems solved by technology

Composite fire doors usually refer to the structure of steel and wood composite molding, which has the characteristics of good fire prevention effect and light weight; in the existing composite fire doors, when the fire door is closed, the door panel directly hits the airtight strip, which is easy to break after a long time of use. It will cause damage to the airtight strip and other structures, which will affect the use effect, and when the door panel hits the wall when it is opened, it will easily scratch the wall, and it does not matter if it affects the wall. Generally, after the fire door is installed, there is a certain gap between the lower end and the ground, and insects can easily enter the corresponding space through the gap, which has certain limitations in use.
