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-sealing casement window for preventing rainwater from leaking in and enhancing sound insulation effect, which is an overall improvement to the existing house casement window, which can be used for the production of new products and can also be used for the production of old products in use. Retrofit. Background technique [0002] Considering the safety problem, the casement windows of the prior art are generally opened to the indoor side, especially in high-rise buildings. The sealing between the window sash and the window frame can only rely on the sealing strip between the outer side of the window sash frame and the inner side of the window frame, but the deformation of the window (or defects during production) and the aging of the sealing strip will cause the window sash and the window frame. If the seal between them is not strict, the rainwater splashed on the outside of the window sash will leak into the room when ...
