Background
With the development of engineering technology, people have higher and higher requirements on the comfort and heat preservation of houses. In recent years, water leakage and ventilation of windows become a major disadvantage which puzzles residents, and particularly, rainwater flows into a room along the window edge and the window frame is common.
At present, the common construction process of the brick-concrete structure at the window part is as follows: building a window wall, plastering and squaring a window, installing the window and performing heat preservation construction on the window. In the window building and plastering construction process, the squareness and the size of the window are construction key points, and slight errors can influence the window manufacturing. Although, the specific size is given when the opening is made by masonry and plastering, an error exists in actual construction, so that the window has different surrounding gap amount when being installed, has a large size and a small size, cannot be glued, and poor gluing can cause poor sealing, water seepage, looseness and ventilation of the window. Moreover, subsequent heat preservation construction can further aggravate plastering and opening errors.
In addition, the brick body is a brittle material, and the construction of drilling and drilling when installing a window can cause the splitting and the crushing of part of the brick body. Along with daily use and various load effects of the window, the splitting and breaking brick bodies can reduce the solid containing capacity of the expansion bolt, the window is loosened, and the sealant is also damaged.
Although, to the solution of the infiltration of window bottom, except strengthening the management and control, still often set up the turn-ups in window position inboard bottom, can effectively block rivers entering. However, the turned-over edge is generally constructed for the second time by bricks, concrete members or cast-in-place concrete, and sometimes the turned-over edge is not well combined with the original structural layer and is easy to loosen and fall off.
