Check the specification and position of the fixing piece
The fixed piece adopts Q235æ¡ cold-rolled steel plate, the surface should be treated with anti-corrosion, its thickness is not less than 1.5mm, and the width is not less than 15mm. The position of the fixing piece should be 150~200mm away from the window angle, middle mullion and middle horizontal frame, and the fixing piece The distance between them should not be less than 600mm. Do not install the fixing piece directly on the stopper of the middle horizontal frame or the middle vertical frame. It is not allowed to install unidirectional fixing pieces, and the two-direction fixing pieces should be installed according to the specification to ensure balanced force.
Fixed window frame
When the window frame is installed in the opening, the upper and lower box lines shall be aligned with the center line of the hole. The four corners of the upper and lower frames of the window and the symmetrical position of the middle horizontal frame shall be temporarily fixed by using a wooden wedge and a pad block. When the length of the lower frame is greater than O. At 9m, the center is also plugged with a wooden wedge or pad to temporarily fix it. Then according to the design drawings, determine the installation position of the window frame in the direction of the thickness of the wall of the opening, and adjust the verticality, horizontality and straight angle of the window frame. The allowable deviation shall comply with the relevant regulations.
Fixed door frame
The lower frame swing door shall be lower than the ground elevation line of the two borders, and the height difference should be 30mm; the lower frame shall be lower than the ground elevation line with the lower frame swing door or sliding door, and the height difference should be 10mm. Measures shall be taken to prevent deformation of the door frame, and then a fixing piece of the upper frame shall be fixed on the wall, and the horizontal, vertical and straight angles of the door frame shall be adjusted and temporarily positioned with a wooden wedge. The allowable deviation should comply with the relevant regulations.
When the doors and windows are fixed to the wall, the upper frame should be fixed first, and then the frame should be fixed. The fixing method should meet the following requirements:
(1) Holes in concrete walls should be fixed by nails or plastic expansion screws.

(3) Aerated concrete openings should be fixed with wooden screws to the pre-embedded adhesive logs.
(4) Holes with embedded iron fittings shall be fixed by welding, or they may be first punched on the embedded part according to the specifications of the fasteners, and then fixed with fasteners.
Filling of window frames and openings
The gap between the door frame and the opening should be filled with closed-cell foam, expanded polystyrene and other elastic materials. The packing should not be too tight. For projects requiring higher insulation and sound insulation levels, appropriate thermal insulation and sound insulation materials should be used. After packing, remove the temporarily fixed wooden wedge or pad, and the gap should also be filled with closed-cell elastic material. Between the window frame and the hole is sealed with a sealant. After installing the sash, pay attention to check whether the amount of splicing in the sash in the sash meets the standard requirements. If there is any hidden danger in quality and safety, it must be completely reworked.
