Mixing and bonding mortar: cement, medium sand with 923 glue to adjust the mortar (1kg: 1kg: .45kg), the consistency is based on the shovel pick up the non-slip, each time the amount is used within 3 hours . Installation: 923 mortar belt of about 5cm and 3cm high is smeared on the four sides of the polystyrene board. The whole board is smeared in the middle (in a zigzag shape). The lower part of the first layer of insulation board is placed on the L-type bracket, facing the wall. Paste on, find the flatness, the smaller the air layer, the better, use a rubber hammer to beat, make it stick firmly, pay attention to the installation: the two sides adjacent to each side of the insulation board have anti-cold bridge polyphenylene strips, installation The first piece of insulation board has a polyphenylene strip placed on the upper side, the vertical side has a polyphenylene strip placed on the left and right sides, and the second board is selected according to the placement position of the first board edge polyphenylene strip. Plate installation (depending on the processing position of the polyphenylene strip, and the matching plate should be placed when the profiled plate is attached). When the second plate is pasted, the plate joint is controlled at about 8mm, and the mortar is bonded between the two plates. Extrusion shall prevail, the extruded mortar shall be flattened, and the second layer shall be staggered and pasted. If the rubber injection molding machine is seamed with mortar, it shall be tightly sealed with a mortar and a horizontal ruler and a ruler at any time during construction. In order to make the insulation board and the wall firmly connected, one layer of the board with the pendant (pre-buried during processing) is installed on every other layer, and the strength of the 923 mortar after the insulation board is reached (usually 24 hours), using the impact drill Use a 1mm diameter drill bit to align the hole on the pendant to make a hole in the wall. The hole depth is 15mm or more (minimum to be more than 3cm into the concrete wall). Use a long self-tapping screw to insert the plastic expansion plug into the hole and tighten. The force of each expansion bolt shall not be less than 1kg, and the mortar shall be leveled after passing the inspection.
