ã€China Aluminum Industry Network】 1 Seal Design The seal design of the unit type doors and windows is very important, mainly including the seal between the units, the seal between the unit and the guard frame, the seal between the guard frame and the hole, and between the units and the unit. Two or more rubber strips shall be used to seal the sealing structure between the protection frames (see Figure 3); the design of the sealing structure between the protection frame and the hole shall be designed according to the different architectural structures. After the insulation between the lower guard frame and the hole is separated, waterproof mortar shall be used for caulking treatment, and between the guard frame and the outer surface of the window opening, waterproof silicone shall be used for sealing treatment.
2 waterproof design Waterproof design is a bright spot for the unit type door and window, unit type door and window can adopt double waterproof design, namely the waterproof design of the door and window unit itself and the second layer of waterproof design inside the lower protection frame, except for setting on the door and window unit, etc. Outside the pressure drain hole, a drain hole is also opened at the connection position between the lower guard frame and the unit body. Rain or condensate entering the chamber under normal conditions is discharged directly from the drain hole on the unit body. If the leakage between the rainwater penetrating or the poor drainage of the unit body caused by the tight seal between the unit body and the protection frame and the condensation water inside the profile cavity can be drained through the second layer of the lower protection frame, the water can be smoothly discharged.
3 Energy-saving design Protection frame and door and window units all use broken bridge heat insulation and heat insulation profiles (with strip or glue injection type), and the width of heat insulation structure can be adjusted according to the requirements of energy saving indicators (see Figure 7). Because the single-chamber plug-in structure is adopted for the design of the unit door and window interface, an elastic heat-insulating material (polystyrene material or polyurethane extruding material) can be conveniently disposed on one side before the connection of the door and window unit, which can effectively hinder the air inside the unit splicing the cavity. Circulation, energy-saving effect far exceeds other similar energy-saving windows, but also played a role in sound insulation, noise reduction.
4 Seismic design The special plug-in mounting structure of the unit type door and window makes the window adaptable to the displacement displacement of the main structure and can effectively absorb the earthquake action, temperature change, and interlayer displacement, and is more suitable for earthquake resistance requirements in different regions than conventional windows and doors.
