Exterior wall aluminum honeycomb panel construction technical requirements: climate conditions
During the construction and within 24h after the completion of the construction, the construction environment temperature should not be less than 5℃, summer construction should avoid direct exposure to sunlight, in the wind above level 5 and thunderstorm days shall not be constructed. Rain protection measures should be taken during the rainy season construction.
Exterior wall aluminum honeycomb panel construction technical requirements two: basic wall requirements
Before the construction, should wall for inspection and acceptance at the grassroots level and bump at the base is not rough, empty drum, scum, such as crack, oil processing, the requirement of cement mortar screed-coat should meet the requirements of intermediate plaster (is a layer of bottom ash, a layer of covering a layer of ash, ash, three times a living, the need for reinforcement, Yang Angle founder, layered leveling, surface pressure light). When the base is particularly dry, the wall base should be watered and embellished before installation.
Exterior wall aluminum honeycomb panel construction technical requirements three: fastener requirements
Number of fasteners: there shall be no less than 1 fastener on each side of each board (except the parts of positive Angle and negative Angle), and no less than 8 fasteners per square meter. The anchoring parts of the phase collar plate should be stagger arranged during installation, and the stagger spacing of the fastener should be 50mm.
Exterior wall aluminum honeycomb panel construction technical requirements four: anchorage requirements
There shall be no less than one anchoring piece on each side, with a spacing of 300 ~ 500mm. The effective anchoring depth of the expansion bushing of the anchoring piece into the reinforced concrete and solid masonry base shall be ≥30mm, and the effective anchoring depth into other light wall base shall be ≥50mm. In the actual construction process, the effective depth of anchorage is generally guaranteed at 60mm.
Exterior wall aluminum honeycomb panel construction technical requirements five: bonding requirements
The aluminum honeycomb plate is connected by point frame method, that is, the width of the uniform special adhesive is not less than 80mm with a spatula on the edges of each aluminum honeycomb plate, and at the bottom of the spatula scraping out about 50mm gap, and then in the middle of the same side of the aluminum honeycomb plate evenly scraping on several bonding points, the diameter of the coating point should be greater than 150mm, The lifting height of the coating points should be greater than 20mm, each square meter should not be less than 6 coating points, and the adhesive area should not be less than 50% of the aluminum honeycomb panel area.
Exterior wall aluminum honeycomb panel construction technical requirements six: construction sequence requirements
Longitudinal construction in the scope of the horizontal control line from bottom to top construction order to stick, horizontal construction to comply with the first positive Angle after the Yin Angle. First ensure the concession structure (such as door, window symmetry, uniformity), and then large area construction.
Construction technical requirements of exterior wall aluminum honeycomb panel seven: requirements of fire isolation belt
In the application process, the fire isolation belt should be set strictly in accordance with the relevant specifications, and the fire protection products with A fire rating should be used. The strip should be glued to the building base, and the fire isolation belt should be no less than 300mm.
