Composite fireproof door and production equipment thereof

Abstract

The invention discloses a composite fireproof door. The composite fireproof door comprises two sets of first door frames which are symmetrically arranged and a second door frame which is matched with the two sets of first door frames for use, wherein guide inserting blocks are integrally formed at the two ends of the second door frame respectively; inserting grooves corresponding to the positions of the guide inserting blocks are formed in the side walls of the first door frames; the guide inserting blocks are inserted into the inserting grooves; placement grooves are formed in upper and lower end faces of the first door frames and the second door frame; the placement grooves formed in the first door frames and the second door frame are vertically adapted; and L-shaped connection blocks are fixedly mounted in the placement grooves through fixing bolts. According to the composite fireproof door disclosed by the invention, the upper and lower sets of L-shaped connection blocks are mounted on the side walls of the first door frames and the second door frame and are used for commonly protecting connection corners of the first door frames and the second door frame, so that the firmness degree of connection between the first door frames and the second door frame is enhanced to a certain extent.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a composite fire door; the invention also relates to production equipment for a composite fire door. Background technique [0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. In addition to the function of ordinary doors, it also has 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 personnel. [0003] The existing wooden composite fire doors are connected and fixed by angle irons with L-shaped cross-sections between the door frames, but their main acceptance points are located at the bends, which can easily cause the angle of the angle irons to change when the force is applied. The connection is poor, and the current wooden composite fire door angle irons are all install...

AI Technical Summary

Problems solved by technology

[0003] The existing wooden composite fire doors are connected and fixed by angle irons with L-shaped cross-sections between the door frames, but their main acceptance points are located at the bends, which can easily cause the angle of the angle irons to change when the force is applied. The connection firmness is poor, and the current wooden composite fire door angle irons are all installed at the corner inside the door frame, which is very inconvenient to install, so we propose a composite fire door and its production equipment
