Common quality problems with glass door and window installation
[China Glass Net] Some workers operate sloppy. When installing glass, the size of the pad or glass blank is not as large as specified. The pad cannot be placed, so that the glass directly contacts the glass groove. The surrounding space is uneven, and the weight of the glass cannot be It is well supported and can cause deformation of the sash when it is severe. The main measures to prevent these problems are as follows. 1 It is stipulated to install the glass block to support the weight of the glass and avoid deformation of the window sash. The glass installed in the vertical frame should be provided with two load-bearing blocks underneath. The distance between the resting points and the vertical edge of the glass is 1/4 of the glass width and not less than 150 mm. In other directions, the block should be set to fix the glass to ensure uniform gaps around. 2 The glass block should be made of hard rubber with Shore hardness of 80. Its width should be greater than the thickness of the supported glass, the length should be no less than 25mm, and the thickness is generally 2~6mm. 3 Before the glass is in place, check the position of the block to prevent the block from falling off due to collision and vibration, and the position is not allowed to block the drain hole. 4 Strictly control the size of the glass cut. The difference between the size of the glass and the size of the frame fan should be equal to the thickness of the two blocks. The glass installation is loose, the rubber sealing strip is detached, the glass installation is not centered, the gap between the glass and the window frame is uneven, the rubber sealing strip is not close to the glass and the window frame, and the installation is uneven. Knocking on the glass by hand, there is a loose sound. The main reason for this situation is that the glass is not properly removed during the installation of the glass, so that the glass and the notch are not centered; the gap between the glass and the glass slot is uneven, and the rubber strip is in poor contact with the glass and the glass groove. Out of the glass slot, the sealing strip can be easily pulled off by hand; the rubber strip is not broken at the corner, and the adhesive is not glued. The main measures for rectification of these problems are as follows. 1 Before installing the glass, carefully remove the debris in the slot, such as mortar, brick scraps, wooden blocks, etc. When the glass is placed, it should be carefully centered to ensure uniform gap on both sides, and fixed in time to prevent collision displacement and offset from the slot. Center of mouth. 2 The rubber sealing strip can not be pulled too tightly, and the length of the blanking is 20~30mm than the assembly length. It should be set in place during installation, the surface is straight, and it is in close contact with the glass and glass slot, so that the surrounding force of the glass is evenly distributed. At the corner, the rubber strip should be cut off with a bevel and glued firmly at the break. 3 When sealing the glass with sealant, the glass should be squeezed with rubber strips or rubber blocks to leave a gap of glue injection. The depth of glue injection should be no less than 5mm. Before the glue is cured, the glass should be kept from vibration.
