Bottom framework of flat window

Abstract

The invention provides a bottom framework of a flat window, the bottom framework comprises three plate bodies which are mutually parallel and arranged at intervals, two inclined plates which inclinedly connect two adjacent plate bodies and more than two check valves which are respectively arranged on two plate bodies, wherein, the check valves can only be pivoted and opened on one direction, thereby leading liquid accumulated in the bottom framework to be capable of flowing along the inclined plates and further ejecting the check valves to flow to the outside of a building; moreover, air at the outside of the building can not be blown into the interior of the bottom framework from the check valves, even the check valve which is arranged to be near to the outside of the building is opened to cause the air to be blown into a window frame therefrom, the bottom framework can still block the air and noise by the other check valve, thereby simultaneously achieving the effects of drainage and sound insulation.

Description

Technical field [0001] The present invention relates to a bottom frame of a plane window, in particular to a bottom frame of a plane window with sound insulation and drainage functions. Background technique [0002] For the needs of daylighting and ventilation, the building will leave openings at appropriate locations during construction, and install windows that can be opened or closed at the openings to isolate the interior and exterior of the building, and achieve protection from wind and rain. Thermal insulation effect. [0003] The prior art windows mainly include a fixed window frame, which is used to surround and fix the inside of the opening of the building, and two windows that are alternately stacked on the fixed window frame front and rear. The two windows are respectively in a window frame. There is a glass, and the two can move in parallel to achieve the effect of opening or closing the window. [0004] Among them, in order to avoid the rust and damage of the window ...

AI Technical Summary

Problems solved by technology

[0005] However, because the fixed window frame and the building cannot be completely sealed, although the window can prevent liquid (such as rainwater) from directly splashing into the interior of the building, it cannot prevent the liquid from flowing along the gap between the fixed window frame and the building. Seepage downwards, if water vapor cannot be eliminated and seeps into the concrete, it will cause wall cancer at the junction of the building and the fixed window frame for a long time, which will not only cause damage to the building, but also affect the health of the residents, so the existing Windows of technology does have room for improvement
