A New Steel Fire-proof Door and Window Frame Plug-in Structure

Abstract

The invention discloses a novel steel fireproof door and window frame inserting structure. The structure is characterized by comprising an equipment body; and the equipment body is composed of a lockhandle, first door frames, second door frames, hinges and a door leaf. The lock handle is embedded into the outer surface of the door leaf, the two first door frames are arranged, the first door frames are located on the left and right sides of the door leaf, the two second door frames are arranged, the second door frames are positioned on the upper and lower sides of the door leaf, the first doorframes and the second door frames are spliced and connected, the hinges are arranged between the first door frames and the door leaf, two frames can be directly manufactured through a mold, fixing ofthe two door frames can be completed through three steps of inserting, moving and knocking-to-bend, installation is easy, different from traditional manual welding, the fixing speed is high, firmnessis good, the labor cost is reduced, and the novel steel fireproof door and window frame inserting structure can be used for large-scale mass production and is high in production efficiency.

Description

technical field [0001] The invention is a novel steel fireproof door and window frame plug-in structure, which belongs to the field of fireproof doors and windows. Background technique [0002] With the rapid development of economic construction and the rapid improvement of people's living standards, people have higher requirements for the construction quality and safety performance of houses; among them, fire-resistant doors and windows have been widely used in various buildings. The installation sequence is generally to install the door frame first. Usually, the connection between the door frames is spot-welded by the manufacturer before leaving the factory, and then polished and painted. This step is usually done manually. [0003] The application number disclosed in the prior art is 201710242107.0, and its structure includes: a steel window frame and fireproof glass. The window frame is welded by four frames, up, down, left, and right. Frame, the first frame is provided...

AI Technical Summary

Problems solved by technology

[0005] To sum up, the problem existing in the prior art is that because the connection between the door frames is completed by welding, there must be a situation of false welding, which will cause the door frame to be easily deformed and fall off under the influence of external force, and due to Manual welding is also not conducive to large-scale production needs. The cost of manual operation is also high, the production efficiency is low, the quality is difficult to be guaranteed, and the production cost is also high. Some welding-free products need to be fixed with screws, and the speed of installation and fixation Slow, you need to carry additional fixing tools, which is not conducive to mass production and installation
