1. Three types of high-rise building exterior wall are required: (1) concrete shear wall (2) clay porous brick filling (3) aerated block filling. (1) The base surface should be first treated with physical tooth or interface agent and then with 1:3 mortar. If the flatness itself is good, it can be treated with the interface agent, and then directly bonded with the bonded mortar. . The metal embossed plate is directly painted with 1:3 cement mortar, the flatness requirement is ≤5mm, and the beam-column lap joint is reinforced with steel mesh cloth according to the specification. Firstly, the surface treatment is carried out with the interface agent, and then smoothed with 1:3 cement mortar, the flatness and the reinforcement of the beam and column are the same; if the thermal insulation board is directly pasted, the interface agent pretreatment is also applied, and the bonding mortar can be used to paste the plate. In short, the flatness and surface properties are the basis for the quality assurance of the external thermal insulation project.

2, paste: paste with a special bonded sand insulation board and wall, using strip paste method or frame point method construction, bonding area, high-level strict control of more than 60%, and gently tapping, leveling, compaction.

3, the seam waterproofing treatment of high-rise building exterior insulation project is most afraid of water seepage problem, a reasonable solution, the board seam is waterproof and reinforced, first with waterproof adhesive sealant, after about 10cm A wide reinforced fiber cloth is added to increase the crack resistance and sealing of the slat.

4. For the construction of plaster and reinforced mesh, if it is constructed with glass fiber mesh, first wipe the first mortar, press it into the glass fiber mesh and reinforce it with plastic anchor bolts, and then wipe the second plastering mortar, the thickness is ≥3mm. If it is reinforced with steel wire mesh, the steel mesh cloth is first fixed on the surface of the thermal insulation board, and then anchored to the wall surface with metal fasteners, and then the secondary surface painting is applied with the plastering mortar, the interval time is >6h, and the thickness is ≥5mm. The construction of the insulation layer is completed and the surface finish of the brick is finished.
