Section bar double-opening casement window

Abstract

The invention discloses a section bar double-opening casement window which comprises an upper window body and two lower-opening window bodies, wherein the top layer of the upper window body is fixed in a first top-layer section bar connecting structure, two side surfaces of the upper window body are fixed in a first side surface section bar connecting structure, the bottom layer of the upper window layer is fixed in a first bottom-layer section bar connecting structure; the top layers of the two lower-opening window bodies are arranged in a second top-layer section bar connecting structure, two outer sides of the two lower-opening window bodies are arranged in a second side surface section bar connecting structure, two inner sides of the two lower-opening window bodies are arranged in a third side surface section bar connecting structure, and bottom layers of the two lower-opening window bodies are arranged in a second bottom-layer section bar connecting structure; the first bottom-layer section bar connecting structure and the second top-layer section bar connecting structure are in sealed and in fitted connection through a first middle connecting structure, two inner sides are in sealed and in fitted connection through a second middle connecting structure. The section bar double-opening casement window is simple in structure, strong in structural symmetry, simple in installation structure, easy to operate, high in stability, freely adjustable in thickness of window bodies, wide in applied range, lowered in production cost, and economical.

Description

technical field [0001] The invention relates to the technical field of building decoration, in particular to a profile double-opening casement window. Background technique [0002] A casement window refers to a door with a hinge (hinge) installed on the side of the door, inward (left inward opening, right inward opening) or outward (left outward opening, right outward opening). It is composed of door pockets, hinges, door leaves, locks, etc. Casement windows include single-open casement windows and double-open casement windows. Single-open door means only one door panel, one side is used as the door shaft, and the other side can be opened and closed. The double door has two door panels, each with its own door shaft, which opens in two directions. Casement windows are divided into one-way opening and two-way opening. One-way opening can only be opened in one direction (only push in or pull out), two-way opening means that the door leaf can be opened in two directions (such ...

AI Technical Summary

Problems solved by technology

[0003] Casement windows are widely loved because of their simple structure and strong practicability, but some of the existing casement windows have relatively complicated structural designs, inconvenient installation of the door body, and the stability of the door body or form after installation. It is also poor, and the thickness of different layers of glass or wooden doors cannot be adjusted well, the scope of application is limited, and the cost is high, which is not cost-effective for users who install casement windows
