Application of metal embossed exterior wall panels on high-rise buildings

1. The base surface requires three forms of high-rise building exterior wall:

(1) Concrete shear wall

(2) Clay porous brick filling

(3) Filling block filling.

(1) The base surface should be chemically treated with physical tooth or interface agent and then brushed with 1:3 mortar. If the flatness itself is good, after the interface agent treatment, the metal embossing can be directly applied after the adjustment with the bonding mortar. Exterior wall panels.

(2) The base surface is directly painted with 1:3 cement mortar, the flatness requirement is ≤5 mm, and the beam-column lap joint is reinforced with steel mesh cloth according to the specification.

(3) The base surface is treated with an interface agent first, and then smoothed with 1:3 cement mortar, flatness and reinforcement of the beam-column side.

(2) If the metal embossed exterior wall panel is directly pasted and also treated with an interface agent, the bonded mortar can be used to paste the sheet. The flatness and surface properties are the basis for the quality assurance of the exterior insulation project.

2, Paste: Use special bonded sand metal embossed exterior wall board to paste the wall, use strip paste method or frame point method to construct, bond the area, the upper level is strictly controlled at 60% or more, and gently tap.

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 reinforcing treatment, first with waterproof adhesive sealant, after 10 Reinforced fiber cloth with a width of about 1 cm is added to improve the crack resistance and sealing of the joint.

4. For the construction of plastering mortar and reinforced mesh cloth, if using glass fiber mesh cloth construction, first wipe the first mortar, press it into the glass fiber mesh cloth and use plastic anchor bolt to reinforce it, then wipe the second surface plastering mortar, thickness ≥ 3mm. If it is strengthened with steel wire mesh, first fix the steel mesh cloth on the surface of the metal embossed outer wall, then anchor it on the wall with metal fasteners, and then use the plastering mortar to paint twice, with an interval of >6h. Thickness ≥ 5mm.
