metal aluminum veneer curtain wall installation and construction plan:
1. Exterior wall curtain wall aluminum veneer installation and construction preparation and instructions
1. Install according to the steel wires laid out by the wiring group and the construction drawings. First, single corner code Spot weld on the embedded parts according to the size line, and then check the position, size and verticality
2. aluminum plate curtain wall installation according to the size number of the aluminum plate at the designed position. The width, horizontality, verticality and plate flatness of the joint seam should meet the specified requirements. Clean the seams and inject glue.
3. Before installation, clean the dirt on the four sides of the aluminum plate to ensure reliable bonding of the embedded weather-resistant glue .
4. The module can be installed only after passing the self-inspection, mutual inspection and special inspection.
5. After the aluminum plate is installed, cover and protect the parts easily contaminated with plastic film. Parts that are easily scratched or touched should be protected by railings.
6. The gap between aluminum plates is generally 10 to 20mm, and should be treated with rubber strips or sealing elastic materials.
7. During the installation process, install according to the number of screws specified in the design. There must be no under-installation. During the installation process, not only the flatness must be considered, but also the size and various indicators of the partitions and must be considered, and the errors must be controlled. Within the range
2. Installation of columns and beams
1. The installation size error of the vertical keel of the entire wall must be digested within the size range of the outer control line, and the error shall not extend outward. The installation of each vertical keel is based on the four lines of control steel near the axis, and is installed in divided sections.
2. After the installation of the vertical keel is completed, check the grid division. If it meets the requirements of the specification, install the transverse keel. The smaller the size of the transverse steel keel, the better. If the gap is too large, welding deformation will occur during the welding process, which will affect The flatness of the entire curtain wall aluminum veneer.
3. After the horizontal materials are installed and spot welded, attention should be paid to the welding sequence during the construction and welding process, and excessive gaps between the horizontal materials and vertical materials should be filled.
4. After the welding process is completed, self-inspection and inspection of the weld quality are required. and geometric dimensions. If the self-inspection is passed, fill in the concealment form and submit it to the supervision for acceptance. After passing the inspection, the welds will be painted with anti-rust paint , and the next process of construction will be carried out.
3. Aluminum plate panel installation and construction and technical plan
process flow : Construction preparation → Inspection and acceptance of aluminum plates → Maintenance of aluminum plates → Stack aluminum plates according to installation locations → Initial installation → Adjustment → Fixation → Acceptance.
Basic instructions :
Construction preparation: Since the installation of aluminum plate panels is the final step in the entire curtain wall installation, preparations must be made before construction. When arranging the plan, arrange the personnel according to the actual situation and the requirements of the project progress plan. Under normal circumstances, 2 to 3 people are arranged in each group. Materials Tools Preparation is to check whether all the aluminum plates on the construction work surface are present and whether there are any arrived or damaged plates. Construction site preparation is to check whether the aluminum plates on the construction work surface are present and whether there are any present or damaged plates. For aluminum plates, the construction site preparation should leave enough space in the construction section to meet the installation needs.
1. Inspection and acceptance of aluminum plates:
The inspection contents include:
(1) Whether the specification quantity is correct and whether the color number is correct and intact;
(2) Whether there are misaligned plates in various parts;
(3) Whether the aluminum plates are stacked reliably;
(4) Whether there are aluminum plates with errors exceeding the standard;
(5) Whether there are damaged aluminum plate panels.
2. The contents of the acceptance include:
(1) whether the three-dimensional error is within the control range;
(2) whether the aluminum plate pendant is damaged and should be replaced;
(3) sampling connection test.
3. During the inspection and acceptance, detailed records must be kept and bound into a book to sign the list of persons participating in the acceptance inspection.
Aluminum panels are stacked according to number specifications: Before installing aluminum panels, the aluminum panels must be cleaned and stacked according to the installation location. At the same time, they must be placed accurately according to the order of installation numbers. The accurate placement must be appropriately tilted to prevent the aluminum panels from overturning
4. Surface maintenance of aluminum panels:
Clean the surface of the aluminum panel;
remove the protective packaging after the installation process is completed;
5. Initial installation: 4 to 6 people per group during installation. The installation has the following steps:
Check to find the aluminum panel; transport the aluminum panel ;Adjust the direction; transport the aluminum plate to the installation position; install the aluminum plate according to the position of the numbered diagram. When installing the aluminum plate, you need to pull the horizontal and vertical control lines, because the entire steel frame is always uneven, and the aluminum plate support points need to be adjusted. Pad flat. During the transportation and hoisting process, the aluminum plate should be transported vertically. It is not suitable to carry the aluminum plate facing up and down the platform. This can avoid the bending and deformation of the aluminum plate.Aluminum plate panel installation
A. Check, measure and adjust the horizontal and vertical connectors before installing the aluminum plate;
B. When installing, the left and right, up and down deviations shall not be greater than 1.5mm;
4. Glue
aluminum It is difficult to glue the veneer curtain wall with hidden glue seams. When glueing, a special ruler is required to be worn on the glue gun to ensure the glue thickness.
1. After the aluminum plate is installed, the foam strips are filled. The foam strips should be selected according to the size of the glue joint. Before filling, cut the foam strips and face the inward side. The filling depth of the foam strips must be consistent, and there must be no unevenness. During construction, a ruler should be used for filling.
2. After filling the foam strips, paste masking paper . The masking paper should be pasted horizontally and vertically without any distortion.
3. During the gluing process, the glue injection should be continuous and full, the squeegee should be even and smooth, and there should be no jumping phenomenon.
Glue seam injection is done from bottom to top, paying attention to the uniformity of the glue injection. After gluing, the surface of the glue seam is scraped and smoothed to overcome some blistering. What is more important is the proficiency and responsibility of the worker. In the morning, glue is injected on the west or north side of the building, and in the afternoon, glue is injected on the east or south side of the building. After the glue is injected, the glue solidifies for a period of time, and the surface layer has formed a skin. When exposed to the sun again, it has a certain resistance and can overcome some blistering. When caulking the weather-resistant metal aluminum plate curtain wall, in hot summer, when the metal plate is exposed to the sun, especially the surface temperature of the aluminum plate will reach 80°C. At this time, the injection of glue can easily cause blistering of the glue joints. Therefore, you should choose to inject glue in the latter half of the afternoon or on cloudy days to improve the blistering situation.
