1. Point-and-frame construction. Use a trowel to coat the four sides of each polystyrene board insulation board (standard board size is 600×1200mm) with insulation board bonding mortar with a width of about 80mm, and leave a vent hole with a width of about 50mm in the middle of the top of the insulation board. , and then evenly scrape 5 bonding points with a diameter of about 100mm on the surface of the insulation board. The bonding points should be arranged evenly, and the bonding area between the board and the base wall must be more than 40%. The base layer should be firmly bonded, and the thickness of the bonding layer should be 5~10mm.
Second, the construction of sticky method. On the surface of each polystyrene board (standard board size is 600×1200mm), use a serrated trowel to fully coat the insulation board bonding mortar with a width of about 80mm. The thickness of the bonding mortar is about 50~10mm, and the spacing between the bonding strips is about 120mm. Ensure that the bonding area between the polystyrene board and the base wall is more than 40%.
For the polystyrene board bonding method, the commonly used point frame method and strip bonding method are selected according to different engineering characteristics.
