Frame steel-lined welded plastic door and window and their manufacture and mounting method

Abstract

The present invention relates to a kind of plastic door and window, belong to the field of plastic door and window production and installation technology. The key points of its technical scheme are follows: (1) welding lining steel into steel frame for window frame, and embedding the steel frame into the building; (2) making plastic shaped material into frame and assembling said frame and door leaf or window sash into finished product door and window; (3) inserting the finished product door or window into the embedded lining steel frame, fixing it with lining steel nails; (4) covering opening of plastic frame material with concrete, foating agent and glass cement to close the lining steel in water-proof and air-isolating cavity.

Description

Technical field: [0001] The invention relates to a plastic-steel door and window for buildings, belonging to the field of manufacturing and installing plastic-rigid doors and windows. Background technique: [0002] Plastic steel doors and windows are widely used for their excellent properties of heat insulation, sound insulation, air tightness, water tightness and corrosion resistance. But also have deficiency: (1) at present, the structure of known plastic-steel door and window frame is: segmental lining steel is fixed on plastic frame section bar inner chamber by screw. Lining steel cannot be welded, and the mechanical properties such as strength and stiffness of the frame are low. Especially, the strength and stiffness of the frame with a mid-stay are lower, which affects the safety of the window. (2) The plastic-steel doors and windows are not resistant to the contamination of the superstructure. Although the doors and windows can be installed after the superstructure i...

AI Technical Summary

Problems solved by technology

But there are also deficiencies: (1) at present, the structure of known plastic-steel door and window frames is: the section lining steel is fixed on the plastic frame profile cavity by screws

Lining steel cannot be welded, and the mechanical properties such as strength and stiffness of the frame are low, especially the strength and stiffness of the frame with a mid-stay are lower, which affects the safety of the window

(2) The plastic-steel doors and windows are not resistant to the contamination of the superstructure. Although the doors and windows can be installed after the superstructure is completed to avoid contamination, it will increase the construction period, and the dimensional accuracy of the superstructure is low. Uniform elastic space required for expansion and contraction of doors and windows

(3) The method of installing doors and windows on the wall with fixing pieces or expansion bolts is not only difficult to operate itself, but also difficult to install directly into windows, and the process of assembling glass and beading on site will lead to installation work, which is time-consuming and affects Window Quality
