How to install metal carved panels in high-rise buildings

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

(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 better, after the interface agent treatment, the metal mortar can be directly pasted after adjustment with the bonding mortar. Plate.

(2) The base surface 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.

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

(2) If the interface is pre-treated with the interface agent, the plate can be pasted with the bonding mortar. The flatness and surface properties are the basis for the quality assurance of the external insulation project.

2, paste: paste with a special bonded sand metal carved plate and then use the strip method or frame method construction, the bonding area, the high-level strict control is more than 60%, and gently tap.

3, the seam waterproofing treatment of high-rise building exterior insulation project is more afraid of water seepage problem, a reasonable solution, the board seam is waterproof and reinforcing treatment, first with waterproof adhesive sealant paint, then use 10 A reinforcing fiber cloth with a width of about cm is added to improve the crack resistance and sealing of the joint.

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 fiberglass mesh and use plastic anchor to reinforce it, then wipe the second mortar, thickness ≥ 3mm.
