High-strength plastic-steel door/window

Abstract

The invention relates to a high-strength plastic-steel door / window, which consists of an integrally welded steel window frame skeleton, an integrally welded steel sash frame skeleton, plastic-steel sections and glass. The plastic-steel sections are buckled on steel pipes of the steel window frame skeleton and the steel sash frame skeleton; and the glass is arranged on the plastic-steel sections. The invention has the advantages that: the integrally welded steel window frame skeleton is taken as a skeleton, and the plastic-steel sections are buckled on the steel pipes of the steel window frame skeleton and the steel sash frame skeleton respectively, so that the manufactured plastic-steel door / window has high strength and long service life.

Description

technical field [0001] The invention relates to plastic steel doors and windows. Background technique [0002] When installing the plastic-steel doors and windows used on large-scale doors and windows (more than 3 meters in length and more than 3 meters in width), the plastic-steel doors and windows are first installed with plastic-steel door and window profiles, and then steel pipes are passed through the plastic-steel doors and windows for reinforcement. The reinforced steel pipes are independent, the reinforcement is not good enough, and the strength of the plastic steel doors and windows is not high enough. Contents of the invention [0003] The purpose of the present invention is to install the plastic-steel doors and windows used on large-scale doors and windows (more than 3 meters in length and more than 3 meters in width). Its weak point is that the reinforced steel pipes are independent, the reinforcement is not good enough, and the strength of the plastic-steel ...
