1. Measure and pay-off
1) According to the axis and elevation line on the main structure, the installation position line of the supporting skeleton is accurate according to the design requirements
Bounce onto the main structure.
2) Punch out all the embedded parts and retest their dimensions.
3) The distribution error should be controlled when measuring the pay-off, not the accumulation of errors.
4) The measurement pay-off should be carried out under the condition that the wind force is not greater than level 4. After pay-off, it should be checked in time to ensure that the curtain wall hangs
Straightness and correctness of column position.
2. Install the connectors to weld and fix the connectors with the embedded parts on the main structure. When there is no burial on the main structure
When the embedded iron parts are pre-embedded, the expansion bolts can be drilled and installed on the main structure to fix the connecting irons.
3. Install the skeleton
1) According to the position of the elastic line, the column with anti-rust treatment is welded or bolted to the connector.
During installation, the elevation and centerline position should be checked at any time for the skeleton column of the aluminum plate curtain wall of the outer wall with a large area and high floor height.
It must be measured with measuring instruments and line sinkers, and its position must be corrected to ensure that the skeleton vertical rod is straight and flat
The deviation should not be greater than 3 mm, the deviation between the front and back of the axis should not be greater than 2 mm, and the deviation between the left and right should not be greater than 3 mm; Two adjacent roots
The elevation deviation of the column should not be greater than 3 mm, and the maximum elevation deviation of the column on the same floor should not be greater than 5 mm, and the two adjacent columns should be erected
The distance deviation should not be greater than 2 mm.
2) The connectors and gaskets at both ends of the beam are installed at the predetermined position of the column, and should be installed firmly, and its joints should be
Tight; The horizontal deviation of the two adjacent beams should not be greater than 1 mm. Elevation deviation on the same floor: when the width of a curtain wall is less than or
It should not be greater than 35 mm at an equal to 5 m; When the width of a curtain wall is greater than 35m, it should not be greater than 7 mm.
4. Install fireproof materials
High-quality fireproof cotton should be used, and the fire resistance period should meet the requirements of relevant departments. The fireproof cotton is fixed with galvanized steel sheet.
The fireproof cotton should be continuously sealed on the vacant space between the floor slab and the metal plate to form a fireproof belt, and there must be no fire in the middle
Gap.
5. Install the aluminum plate
According to the construction drawing, the aluminum alloy plate veneer is fixed on the steel skeleton block by block with rivets or bolts. Leave seams between the plates
10~15 mm in order to adjust the installation error. When the metal plate is installed, the deviation from left to right, up and down should not be greater than 1.5 mm.
6. Deal with the plate seam
After cleaning the metal plate and frame surface with a detergent, immediately place the sealing strip in the gap between the aluminum plates
or weatherproof adhesive strips, and then inject silicone weather-resistant sealant and other materials, and the glue injection should be full, without gaps or bubbles.
7. Handle curtain wall closing
The closing treatment can use metal plates to cover the end of the wall panel and the keel part.
8. Deal with deformation joints
To deal with deformation joints, we should first meet the needs of building expansion and settlement, and at the same time, we should also achieve the decorative effect. Can often
Adopt heterosexual gold plate and neoprene belt system.
9. Clean the board surface
Remove the adhesive paper and clean the board.
