ã€China Aluminum Network】 Dry aluminum panels are resistant to acid rain, salt spray, and various air pollutants due to their excellent corrosion resistance and weather resistance, excellent resistance to cold and heat, and strong ultraviolet radiation resistance. Long service life has been favored by many consumers. The following small series will introduce dry hanging aluminum veneer construction technology.
1. Measure the payoff line 1) According to the axis and elevation line on the main structure, according to the design requirements, the installation position line of the support frame will be accurately projected onto the main structure.
2) Make all the embedded parts out and re-measure their size.
3) The distribution error should be controlled when the line is measured, not the error accumulation.
4) Measurements should be carried out under wind conditions of not more than four levels. After the release of the line should be promptly checked to ensure the verticality of the curtain wall and the correct position of the column.
2. Install the connector to fix the connector and the embedded part on the main structure. When the embedded iron member is not embedded in the main structure, holes can be set in the main structure to fix the expansion bolts and the connecting iron pieces.
3, installation skeleton 1) according to the position of the bullet line, the rust-proof post is welded or bolted to the connector. At the time of installation, it is necessary to inspect the height and centerline position of the large-scale, high-rise aluminum wall aluminum frame wall column, must be measured with a measuring instrument and line fall, adjust its position, to ensure that the vertical shaft skeleton and straight . Column installation elevation deviation should not be greater than 3?, axis before and after the deviation should not be greater than 2?, left and right deviation should not be greater than 3?; adjacent two vertical column elevation deviation should not be greater than 3?, column column elevation deviation should not be greater than 5 ?, two adjacent vertical distance deviation should not be greater than 2?.
2) Install the connectors and gaskets on both ends of the beam at the predetermined position of the column, and install it firmly. The joints should be tight; the horizontal deviation of two adjacent beams should not be greater than 1?. Level elevation deviation: when the width of a curtain wall is less than or equal to 35?, when the width of a curtain wall is greater than 35m, it should not be greater than 7?.
4, install the aluminum plate to measure the pay line according to the construction drawing with aluminum rivets or bolts to block the aluminum-plastic plate block on the steel frame. Leave 10-15 inches between the board and the board to adjust the mounting error. When the aluminum plastic plate is installed, the deviation between left and right, up and down should not exceed 1.5?.
5. After cleaning the surface of the aluminum-plastic panel and frame with a cleaning agent, immediately place a weather strip or weatherproof rubber strip in the gap between the aluminum panels, and then inject silicone weather-resistant sealant and other materials. Full, no gaps or air bubbles. 6, Treatment of the closing of the curtain wall The metal plate can be used to cover the end of the wallboard and the keel.
7. Dealing with deformation joints Disposing deformation joints must first meet the needs of building expansion and contraction and settlement, and should also achieve decorative effects. Can often use the opposite gold plate and neoprene belt system.
8, clear the board to remove the board to protect the plastic sheet, clean the board surface.
The above is an introduction to the construction technology of dry-hanged aluminum veneer, and it is hoped that it will be helpful for everyone to carry out dry-hanging aluminum veneer construction. In addition, Xiao Bian also needs to remind you that during construction, you must pay attention to the personal safety of yourself and pedestrians, so as to avoid unnecessary safety accidents.
