Modified doorframe structure of fireproof antitheft door

Abstract

Disclosed is a modified doorframe structure of a fireproof antitheft door. The n-shaped doorframe comprises a horizontal frame bar and two vertical frame bars arranged at the two ends of the horizontal frame bar. A layer of veneer is adhered to the exposed surfaces of the frame bars, holes are arranged on the lower surface and at two ends of the horizontal frame bar, the upper ends of the vertical frame bars are provided with raised inserts, the inserts which are matched with the holes in shape, direction and size are inserted into the holes, and then the inserts are folded by 90 degrees from the roots and welded to the horizontal frame bar, so that the lower surface of the two ends of the horizontal bar are closely bound up with the upper end surfaces of the vertical frame bars to form the n-shaped doorframe. The modified doorframe structure of the fireproof antitheft door is fine in fireproofing performance and attractive in appearance. During a fire, the burning of the veneer only creates a small amount of smoke so that the basic fireproofing function of the fireproof antitheft door cannot be affected. The modified doorframe structure is environment-friendly, low in manufacturing costs, simple in processing and high in automation degree, and enables working intensity of workers to be reduced.

Description

technical field [0001] The invention relates to the field of fireproof and antitheft doors, in particular to an improved structure of a door frame for a fireproof and antitheft door. Background technique [0002] At present, the country has two main requirements for the entrance door. On the one hand, the "Code for Residential Design" clearly requires that the entrance door should use anti-theft safety door. On the other hand, from the perspective of fire protection, the entrance door must have fire protection function. [0003] In order to meet the functions of fire prevention and anti-theft at the same time, the existing entrance doors usually adopt the structure of steel door frame and door panel. The steel door frame door panel can prevent the fire source from expanding in time when a fire occurs, and also has sufficient anti-destructive ability. However, if the steel door frame and door panel structure is directly exposed to the outside, it often does not match the over...

Problems solved by technology

[0008] Second, the consumption of wood is relatively large

The thickness of decorative wood strips / boards is generally 5-8cm, and the consumption of solid wood boards is relatively large during mass production, which is not conducive to environmental protection and high manufacturing costs;

[0009] The third is that the decorative surface of the door frame door panel needs to be fastened on the door frame door panel body with multiple bolts. First, a plurality of installation holes must be allocated on the door frame door panel and the decorative wooden strips, and then the workers will install the bolts to fix them. Trouble, especially the shape of the exposed surface of the door frame is more complicated, the process is more cumbersome, and the labor intensity of the workers is high
