Description

An outer window frame waterproof node structure

technical field

The utility model relates to the technical field of anti-leakage construction of building exterior windows, in particular to a waterproof node structure of an exterior window frame.

Background technique

During the installation and construction of the outer window frame of the building, in order to prevent the perennial rainwater erosion and the seepage of the window frame, according to the requirements of the door and window in-depth design nodes and construction specifications, it is necessary to do waterproof packing at the junction of the window frame and the outer wall of the building. Usually, after the exterior window frame of the building is fixed, the surrounding of the window frame should be filled with foamed polyurethane, and the surface should be sealed with sealant to prevent rainwater from penetrating into the room.

At present, the filling treatment around the window frame is one of the key nodes for preventing leakage of the outer window. In the design and construction process of the node, the method required by the specification is mostly used, that is, the polyurethane foaming agent is filled between the wall and the window frame. Then paint the waterproof mortar on the outside of the window frame to close the mouth. There is also an improved construction process that considers sticking the waterproof membrane outside the lower mouth of the window frame, that is, adding a membrane under the mortar painting surface to improve the waterproof effect. However, in the process of on-site construction quality control, the above process practices not only need to ensure tight bonding between different materials, but also need to consider the temperature between different materials (such as foaming agent, coil, mortar, sealant, etc.) Shrinkage deformation and improper handling will cause the mortar at the lower opening of the window frame to crack, which requires higher control of each link in the construction process.
