Plastic steel doors and windows are favored by consumers due to their good sealing performance, water resistance and low price. Plastic steel doors and windows are also a form of doors and windows actively promoted by the state. The manufacture of plastic steel doors and windows is relatively convenient, so the manufacture and installation are mainly made of some small and medium-sized enterprises. Although plastic steel doors and windows have been widely used in our country, there are still some problems in the manufacture and installation.
Regarding the installation process of plastic steel doors and windows, it is relatively difficult to process the drainage hole in the middle slide of sliding window. Is there any problem of opening the drainage hole?
The answer is of course to be set, otherwise the rain will choke when the wind blows. If there is no place to discharge the water, it will come into the house along the Casement closed place. Generally, the drainage hole is left in the middle of the sink with the bottom window frame of Casement, about 1cm x0.5 cm, so that when the water is left, it can be discharged along the small hole.
The principle of plastic steel window drainage hole is based on isobaric structure principle.
Function of plastic-steel window drainage hole: If rainwater enters the water chamber, it can use the self-weight of water to discharge accumulated water to prevent rainwater from pouring back into the room, thus playing the role of preventing window leakage.
1. If it is an inner flat window, open 2 drainage holes in the frame under Casement. It is required to be 30-50mm from the corner. The fixed glass part is best sealed by weather proofing sealant outside the glass, which has good waterproof effect.
2. If it is an ordinary casement window, it is needless to say. If you don't pay much attention to it, it is empty. If you push and pull it, the drain hole gap between the two slides is not less than 10 centimeters, and another slide needs two blanks, these two blanks cannot be below Casement.
Method:
Generally, plastic-steel doors and windows have good sealing performance. Because the temperature difference between indoor and outdoor is relatively large in winter, water drops on the plastic-steel windows are condensed, so the water in the middle gap of the plastic-steel windows is difficult to discharge, it is difficult to process the drainage hole of the middle slide of the plastic-steel window, and the work of processing the drainage hole in the middle is much more difficult than that of processing the drainage hole in the outer slide, it is common to use a long drill bit to drill holes at the selected position from the end of the window frame at a certain angle before welding frame, and the method of using T-type milling cutter to directly milling the end is also very common.
