fire door frame

Abstract

The invention discloses a frame of a fireproof door. The frame comprises a first base panel and a second base panel. The first base panel is located on the side, toward a wall, of the frame of the fireproof door, and the second base panel is located on the side, toward a door leaf, of the frame of the fireproof door, wherein the first base panel is connected with the second base panel through an inorganic binder and gun nails; the first base panel and the second base panel are obtained by clipping flame-retardant and fireproof straw panels in certain sizes, and the side, in contact with the wall, of the first base panel is reinforced in segments by a plurality of U-shaped steel reinforcers. According to the frame, traditional door frames with wooden structures are abandoned, and the environmentally friendly and flame-retardant straw panels are creatively adopted to replace woods for manufacturing door frames, which save resources and effectively reduce environmental pollution brought by straw burning. According to the frame of the fireproof door, the combustion performance conforms to the specified requirements of the level A1, the smoke toxicity conforms to the specified requirements of the first safety class, and the performance is excellent.

Description

technical field [0001] The invention relates to a door frame profile, in particular to a fireproof door frame profile, which belongs to the technical field of fireproof materials. Background technique [0002] With the rapid rise of the construction industry, the manufacturing technology of fire doors has further developed and matured, and the quality of fire doors has become a necessary factor for each household to choose; and the choice of door frames as the installation carrier of fire doors is also extremely important. Traditional fire door frames generally Made of steel or wood. Steel door frames are usually provided where the resistance to the spread of flame must be greater than one hour; while wooden door frames are generally more susceptible to fire and are therefore used on doors where resistance to the spread of flame is required for less than one hour. [0003] The Chinese patent No. 00215291.6 discloses a composite door frame, which includes an outer cladding a...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art, and is to provide a fireproof door frame with excellent fireproof performance. Flame retardant, no carbonization, no deformation, no harmful smoke and gas generation at high temperatures above 1200 ℃, and high temperature does not conduct heat, and does not expand when exposed to water, which completely solves the problems of incomplete flame retardant and easy burning of wooden frame wood materials
