High-tightness casement window capable of preventing leakage of rainwater and improving sound-insulation effect

Abstract

A high-tightness casement window capable of preventing leakage of rainwater and improving a sound-insulation effect comprises mullions and borders, and pieces of fixing glass and casement window sashes are respectively mounted in adjacent windowpanes. Groove slide rails which correspond to one another are arranged on upper and lower surfaces and left surfaces or right surfaces of the windowpanes, are positioned on outer sides of the casement window sashes and extend to lower surfaces and outer surfaces of outer sides of the pieces of fixing glass of the adjacent windowpanes, pieces of push-pull glass capable of covering the casement window sashes are arranged in the groove slide rails, and outer side surfaces, which are adjacent to the casement window sashes, of the mullions are positioned inside inner side surfaces of the pieces of push-pull glass. The high-tightness casement window has the advantages that the pieces of push-pull glass are pulled to the leftmost edge of the high-tightness casement window to cover the outer sides of the casement window sashes when in heavy rain, rainwater cannot splash to the outer sides of the casement window sashes after the casement window sashes are closed, and the problem that rainwater flows along the outer sides of the casement window sashes and leaks into an indoor environment from lower sides of the casement window sashes is completely avoided. Besides, the pieces of push-pull glass cover the outer sides of the casement window sashes, so that the sound intensity is greatly reduced, and the sound-insulation effect is obviously improved.

Description

technical field [0001] The invention relates to a high-seal casement window that prevents rainwater from leaking in and enhances the sound insulation effect. It is an overall improvement to the existing casement windows of houses, and can be used as a new product or as an old product in use. remodel. Background technique [0002] The casement window of the prior art considers the problem of safety, and the sash generally all opens to the indoor side, especially in high-rise buildings. The seal between the sash and the window frame can only rely on the sealing strip clamped between the outside of the sash frame and the inside of the window frame, but the deformation of the window (or defects during production) and the aging of the sealing strip will cause the sash and the window frame The seal between the casement windows is not tight, and the rainwater splashed to the outside of the window sash will leak into the room when it rains. This is a long-standing problem with case...
