Description
Technical Field
The invention relates to a building waterproof technology, in particular to a windowsill waterproof method and a windowsill waterproof technology.
Background
The window is not opened in a building house, the windows commonly used by people at present comprise wood windows, plastic windows, aluminum alloy windows and other windows, and the windowsill is easy to seep water due to rainwater, and particularly the water seepage phenomenon of the windows in temperate regions and tropical regions is very serious; most of the water leakage of the window permeates into the wall through the windowsill and then gradually permeates into the room; in part, the leakage of water is caused by the fact that the wall under the windowsill is soaked by a large amount of rainwater for a long time.
The manufacturing process of the window is firstly supposed to be perfect in sealing, such as hollow glass sealing, window frame corner combining part sealing, corner combining fracture part sealing, middle support part sealing, sealing between glass and a window frame and other detailed sealing parts of the window are all intact, but even if the window with excellent protection is installed on a wall body, the water leakage phenomenon can occur at positions such as a windowsill and the like.
For window installation companies, rough or defective installations do result in water leaks. However, even if the installation is re-standardized, the water leakage still occurs when the installation is not strict.
People mistakenly think that the water on the window table surface is drained to the outer wall, and the water cannot leak; in fact, most of the rain does drain from the sill, but a small proportion of the water still seeps into the wall below the sill.
Somebody thinks that the outdoor windowsill surface of the window is high by mistake, and the indoor windowsill surface is low, so that water flows into the indoor windowsill surface from high to low. Therefore, the indoor window table is lifted, and the result is infiltrated as is, but the water is infiltrated to the lower part of the indoor window table.
Exactly what is the reason why is the windowsill leaking water? The practical situation is that ceramic tiles or ceramic bricks on the windowsill, pointing putty or exterior wall paint on the windowsill cannot completely resist water penetration for a long time; water permeates into the concrete which is batched when the concrete is filled from capillary holes or fine cracks of the surface materials of the window table and the side surfaces of the window; one path of rainwater permeating into the facing material permeates into a room through the window opening, and the other path of rainwater permeates into a wall body below the table top.
Even if the facing material is made to be good and dense, the facing material is beautiful and flawless, but the facing material and the concrete inevitably crack in micro areas under the action of climate temperature difference, aging of building materials, water absorption and water loss of the concrete and the like; because of different expansion coefficients of various materials, cracks are inevitably generated under the action of temperature difference in day and night or between summer and winter, and in addition, the invasion of moisture and surface drying are carried out, and in the circulating process, the cracks are further expanded; the outer counter surface material of the window is thus impervious to the ingress of water. In conclusion, the research on solving the problem of water seepage of the window is a significant work.
