Description

Technical Field

[0001] The utility model relates to a window opening structure of a building exterior wall. Background Art

[0002] Windows on the exterior walls of buildings can let in natural light and provide good lighting conditions for the indoor environment. Windows are an important part of buildings. Compared with artificial lighting, natural light is softer and helps improve the visual comfort of residents. Having good lighting effects can not only save energy costs, but also reduce pollution to the environment. At the same time, sufficient natural light is also conducive to people's physical and mental health and improves the efficiency of work and life.

[0003] Window sills are usually installed in the window openings on the exterior walls of buildings. During the installation process, the gaps are filled with caulking agents to achieve sealing and waterproofing. Finally, primer is applied to the exterior wall of the window to enhance the adhesion of the waterproof coating. Waterproof tape or waterproof glue is required to seal the edges and joints of the window to enhance the waterproof performance of the window edges.

[0004] However, when a house reaches a certain age, it will inevitably sink or crack at the joints. House settlement refers to the phenomenon that the foundation of a building is displaced and deformed due to the influence of geological, topographical, climatic and other factors. When a house is subjected to external forces, it will cause the ground to sink or bulge, tilt or even crack, which is called uneven house settlement. House settlement refers to the phenomenon that the foundation of a building is displaced and deformed due to the influence of geological, topographical, climatic and other factors. In particular, the bottom edge of the window opening on the exterior wall of the building is the main load-bearing part, so cracks are very likely to appear on the bottom edge of the window opening. The connection between the window opening and the window sill on the exterior wall of a building is a location that is extremely prone to cracking due to settlement. In addition to cracking, aging and powdering of the organic sealant (foaming glue) filled in the gap are also the main causes of the cracks. However, after the window sill is installed in the window opening on the exterior wall of the building, the gap between the window opening on the exterior wall of the building and the window sill is extremely small, the gap may be covered by the exterior wall paint, and the ventilation position is unclear. Therefore, it is difficult to repair when ventilation or water seepage occurs. Utility Model Content
