Stress-enhanced-type plastic sectional material

Abstract

The invention discloses a stress-enhanced-type plastic sectional material. The stress-enhanced-type plastic sectional material comprises a first sectional material body and a second sectional materialbody which are each in a long-strip shape; a rectangular cavity is formed in the middle of the first sectional material body, and an elastic assembly is arranged in the cavity and comprises two mutually-parallel long-strip-shaped aluminum plates; two rows of springs are arranged between the aluminum plates in the extending direction of the long edges of the aluminum plates, and the two ends of the springs are fixed to the inner sides of the two aluminum plates; a row of cylindrical sunken parts is formed in the surface of the outer side of each of the two aluminum plates at equal intervals, and flat-circular magnet pieces are arranged in the sunken parts; and the section of a second sectional material main body is in an L shape, an L-shaped passage hole penetrating through the second sectional material body is formed in the sectional material main body, and an angle steel strip is arranged in the passage hole. The stress-enhanced-type plastic sectional material can be used for manufacturing a door frame and a door leaf and releases impact force borne by the single contact faces of the door frame and the door leaf at the moment of door closing to the larger area, the bending-resisting capability of the door frame is enhanced, and thus the service life of an entrance door is advantageously prolonged.

Description

technical field [0001] The invention relates to a plastic profile, in particular to a stress-enhanced plastic profile for making plastic-steel doors. Background technique [0002] Polyvinyl chloride (UPVC) resin is a commonly used building material, which is widely used in the production of doors and windows of houses. Compared with traditional steel windows, wooden windows and aluminum alloy doors and windows, the heat insulation and sound insulation properties are greatly improved. Plastic steel doors and windows are made of polyvinyl chloride (UPVC) resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc., extruded into profiles, and then cut, welded or screwed. Door and window frame leaves are made by this method, equipped with sealing strips, tops, hardware, etc., and at the same time, in order to enhance the rigidity of the profile, steel lining (reinforcing rib) needs to be added to the cavity of the pro...

AI Technical Summary

Problems solved by technology

However, the steel lining can only prevent the bending of longer profiles to a certain extent, but for local collisions, it cannot play the role of releasing the impact force of the collision.

Especially for plastic-steel doors, the moment the door is closed, the impact force of the collision between the door frame and the door leaf is relatively large, and long-term collision will inevitably lead to deformation of the door frame and door leaf, which in turn will cause adverse consequences such as air leakage and rain leakage. Therefore, it is necessary to design A plastic-steel profile with strong impact resistance, used as the base material for plastic-steel doors and windows
