Some people ask if you need pads under the installation of doors and windows glass? For this question, we checked the relevant knowledge, and the answer is needed, because we all know that we usually install doors and windows first, and the auxiliary frame has a certain gap with the wall, in order to achieve the balance of the door frame during installation, we all need to have a cushion pad Wall and sub-frame, then measure the level with horizontal ruler, and then hit fixed studs. Therefore, it is necessary to install cushion blocks in doors and windows.
The glass pad should be made of hard rubber or plastic, and recycled rubber, wood piece or other absorbent materials should not be used.
After the layering is assembled, it should be strong, and the gap at the butt joint should not be more than 1mm.
The overlapping amount of Glass and Window is calculated from the edge of the window frame and fan, and the overlapping amount of each side should not be less than 8mm (the double glass should not expose aluminum spacing strip), and when the glass is assembled, glass pads must be added below.
2. Before installing and installing aluminum alloy doors and windows, the positions of vertical, horizontal (elevation) and wall thickness must be determined; When installing the clean opening, the reserved gap between the window frame and the opening finish is 5-8mm, make sure that the gap between the upper and lower sides and the left sides is uniform during installation. The thickness of the connecting piece shall not be less than 2mm when the wool mouth is installed. The diagonal deviation of the installation window frame is ≤ 2. 0mm; The verticality deviation of front and side frames (including splicing materials) is less than or equal to 2. 0mm; The horizontal deviation of window frame (including splicing materials) is less than or equal to 1. 5mm; Elevation error ≤ 5. 0mm. Fixing method: when installing the clean mouth, use the expansion hose to fix the window frame directly on the wall; When fixing, the screws must be tightened with a screw knife. It is forbidden to knock them directly with a hand hammer, use the expansion hose to fix the window frame on the wall through the connecting piece. No matter what method is fixed, the fixing point shall not exceed 600mm, and the fixing part shall not enter the main body of the structure less than 50mm.
After the installation of the door and window frame, there should be no phenomena of arch, droop, warpage and deformation, so as not to hinder the function of the switch; Before installing the glass, the mortar and sundries in the groove should be removed to make the drainage hole unblocked; casement after installation, the appearance quality and surface are clean, without large area pitting, scratches, bumps, rust and other phenomena; The surface of the sealant is smooth, regular and free of bubbles. The finished parts are installed completely and firmly, and there should be no misfitting or short-shipment phenomenon; After the sealing strip is assembled, it should be uniform and strong. At the box angle interface, it should be tightly bonded, without groove removal, and there should be no gap break.
The Broken Bridge doors and windows installed in the vertical frame should be placed on two identical positioning pads, and the placement point should be separated. Broken bridge aluminum doors and windows the distance between the vertical edge should be 1/4 of the width of the broken bridge doors and windows, and should not be less than 150mm. The Broken Bridge doors and windows installed in the fan should confirm the orientation of the positioning pad according to the open direction. The width of the positioning pad should be greater than the thickness of the supported broken bridge doors and windows, and the length should not be less than 25mm, and should meet the planning requirements. Broken Bridge aluminum doors and windows after the installation is in place, its edge shall not touch the frame, fan and its fittings, and the space left shall be 2~3mm. Broken Bridge aluminum doors and windows all kinds of materials used during installation shall not affect the smoothness of the drainage system. When the doors and windows of the Broken Bridge are inserted into the frame and fan, and the filling materials and pressure lines are fill plug, the force around the doors and windows of the broken bridge should be evenly rolled. The safety and civilized construction objectives of doors and windows project are: the safety accidents above minor injuries are zero. Before the construction site is regular and civilized, all mechanical installation should be checked, debugged and passed, and after inspection, it can be put into use.
As we can see, pads are basically used.
