Technical Field
The utility model belongs to the waterproof field of building, more specifically relates to a window frame upper portion eaves mouth waterproof construction.
Background
The window is an indispensable part of the house, and has three functions: firstly, improve indoor daylighting rate, secondly play the effect of ventilation, three, some windows still have thermal-insulated function, can avoid indoor supercooling or overheated. Windows determine to a large extent the quality of life of the people. However, in recent years, there is an increasing problem of water leakage from windows, which not only damages the interior decoration but also affects the quality of life of people to a certain extent.
The leakage of rainwater to occur in a window needs to satisfy three conditions: firstly, gaps around the window frame exist in water; secondly, a gap capable of water seepage exists on the surface of the window or in the cavity of the window; thirdly, certain force is needed for water to permeate into the window, such as pressure difference, air flow and the like. One condition is not met, rainwater cannot leak into the window, and the rainwater falls onto the outer wall of the window, so that the rainwater is an objective natural phenomenon and is unavoidable. Only the treatment is carried out on the passage (namely the gap) so that the rainwater is drained in time and does not flow into the gap and leak into the cavity of the window, thereby causing indoor leakage.
However, there are many reasons for window leakage, and the important and critical point is the gap around the window frame. Many solutions have also been proposed: for example, the publication No. CN113006639A, a water seepage prevention window, which is added with a flashing board to protect the wall of a windowsill and solve the problem of water seepage of rainwater to the windowsill.
