Assembled external windowsill waterseepage-prevention structure system and assembled external windowsill waterseepage-prevention construction method

Abstract

Provided is an assembled external windowsill waterseepage-prevention structure system. The assembled external windowsill waterseepage-preventionstructure system comprisesan assembled sloping externalwindowsill coping mounted on anexternal wall surface and composed of precast concrete, a window frame mounted on the external windowsill coping, and internal and external wall decorative surfaces. Theassembled sloping external windowsill coping comprises a window frame mounting portion and embedded portions at the two ends of the window frame mounting portion; and a cross-section of the window frame mounting portion is in a low-outside and high-inside slope shape, and cross-sections of the embedded portions are rectangular cross-sections. In the assembled state, the assembled sloping externalwindowsill coping is placed on the external wall surface through slurry, the embedded portions at the two ends are embedded into an outer wall, and the window frame is installed on the inclined surface of the window frame mounting portion of the assembled sloping external windowsill coping and is leveled by caulking materials. The assembled external windowsill waterseepage-prevention structure system is simple in design and convenient to construct, and does not need to be grouted in an embedding section; the problems of cracks easily caused and secondary water seepage due to excessively thickslurry in the embedding section can be solved, the impermeability of the windowsill coping is improved, and the construction period is shorten.

Description

technical field [0001] The invention relates to a construction method in the technical field of building construction, in particular to an assembled outer window sill anti-seepage structure system and an assembled outer window sill anti-seepage construction method thereof. Background technique [0002] At present, most of the window sill topping and external window sill anti-seepage construction methods are to build the window sill masonry to the design height, and then carry out the construction of the window sill topping. This technology determines the pouring height of the external window sill (the height of both sides is the same) through the on-site spring line. Install the window sill formwork, place the window sill reinforcement, and then pour the concrete to press the top, and the window sill is pressed and the concrete is cured. [0003] The disadvantages of this technology are: it is time-consuming and wasteful to install the roofing formwork on site, and it is eas...

Problems solved by technology

[0006] The purpose of the present invention is to provide an assembled external window sill anti-seepage structure system and its assembled external window sill anti-seepage construction method. The assembled slope-shaped external window sill topping is an improvement on the existing "prefabricated window sill topping structure" and construction methods In addition to pressing the window sill to the top in the component factory to make a slope shape with a low outside and a high inside, the embedded section is also made into a flat type, which solves the problems of external window seepage, rainwater backflow and external windows of high-rise buildings in the existing on-site construction. In addition to the construction problems, it also solves the inconvenience of the construction of the patent announcement number CN205035899U and the invention name "Prefabricated Window Sill Roofing Structure" that must be leveled by sitting in the embedded section, and the cracking that is easily caused by too thick sitting in the embedded section , cause secondary water seepage and other problems, can effectively reduce the probability of window sill water seepage, and speed up the construction time
