Energy-saving casement window

Abstract

The invention relates to a building door and window, in particular to an energy-saving casement window with good sealing property. The invention aims to provide an energy-saving casement window with good sealing property, which has the characteristics of simple reasonable structure, factory production, quick and convenient mounting and better heat insulating and energy saving effect. The inventionadopts the technical scheme that the energy-saving casement window is provided with a frame comprising a left rim and a right rim which are opposite to each other, as well as an upper rim and a lowerrim which are vertically connected. The energy-saving casement window is characterized in that the frame is divided into a fixed frame and an open frame through a mullion; the fixed frame is internally embedded with glass, and the open frame is provided with at least one movable sash which is connected with the open frame through a friction hinge; and the movable sash is also internally embeddedwith glass.

Description

technical field [0001] The invention relates to a building door and window, in particular to an energy-saving casement window with good sealing performance. Background technique [0002] Most of the houses built in our country in the 1990s use solid-web steel windows, which have been obviously aged and corroded due to natural physical and chemical factors; It affects the normal use of steel windows, and there are many potential safety hazards, and the appearance is also very unattractive, so it is urgently needed to transform it. Most of the existing houses use plastic-steel windows, which are basically not used in the construction industry, especially in high-rise buildings, due to their rapid aging and low strength. [0003] The common transformation method is to completely dismantle it, that is, to dismantle all the window frames and sash, it must be dismantled by knocking, shaking, etc., which will not only directly affect the structure and anti-seismic effect of the ho...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the 45-degree splicing between the frame material and the movable window frame, the section of the profile is relatively single. During use, the interface is easily subject to vibration due to external forces. That is, cracking occurs, which directly affects the use effect of the casement window and shortens the service life of the casement window

[0005] 2. Since this type of casement window does not have an insulation layer on its structure, the effect of heat insulation and energy saving is not ideal
