Operation
Find the regular elastic line and find the installation position of the door and window frame → cover fan and installation template → window frame and fan installation → door frame installation → door fan installation
Find the regular elastic line: After the structural engineering passes the verification, you can hang it vertically with a large wire from the top layer, check the accuracy of the window position, and eject ink lines on the wall. deal with.
1) The height of the window frame installation should be checked according to the indoor + 50cm flat line, so that the window frame is installed at the same level.
2) The outdoor interior door frame should be installed according to the drawing position and elevation, and the number of wooden bricks should be reasonably set according to the height of the door. Each wooden brick should be nailed with two 10 cm long nails and the nail cap should be smashed into the wooden bricks. Make the door frame securely installed.
3) Lightweight partition walls should be preset with concrete blocks with wooden bricks to ensure the firmness of the installation of doors and windows.
3. Covering fan and installation template: Install the window sash on the window frame according to the requirements of the drawing. This process is called covering fan. For the quality of the cover fan, check the gap size, hardware position, size and firmness according to the evaluation standard, and meet the standard requirements as a model, which is used as the acceptance standard and basis.
4. The thickness of the plaster layer should be taken into account when installing the window frame fan with elastic line, and the installation position line should be drawn on the wall according to the size, elevation, position and opening direction of the door and window. Doors, windows, and standing frames with faces should be flat to the plastered surface, and windows with prefabricated terrazzo panels should pay attention to the wall exit size of the window sill plates to determine the position of the standing frames. Neutral exterior windows, such as when the outer wall is a seam of clean water brick wall, can be slightly moved, it is advisable to cover the brick wall vertical seam.
The height of the installation of the window frame is based on the + 50cm flat line on the wall. Use a wooden wedge to temporarily fix the frame in the window hole. To ensure the straightness with the separated window frame, a small line should be drawn below the window frame to straighten it. The iron spirit level introduces the flat line into the hole as the standard for the vertical frame, and then straightens it with a wire drop. Before installing the Huanghuasong window frame, aim at the drill holes of the wooden bricks for easy nailing.
