Pressure injecting caulking construction technique for gaps between building door/window hole and common additional frame or side frame

摘要

A pressure injecting caulking construction technique for gaps between building door/window hole (4) and common additional frame or side frame (1), which involves steps as follows. Firstly, positioning the common additional frame or side frame (1) of the building door/window in the hole (4). Secondly, the technique includes injecting insulating materials (7) in the middle of the gap (3) between the frame and hole, or installing occulting bars (2) at outer side of the additional framework or side framework, or installing combined frameworks (9) on the sides of the common additional frame or side frame and the wall of the hole. Lastly, the technique includes pressure injecting filling materials into the gap (3).
