Aluminum Plate Curtain Wall Installation and Construction Plan\r\n\r\n1.\tAluminum Plate Curtain Wall Installation and Construction Preparations and Instructions\r\n1. Based on the steel wires laid out by the pay-out group and combined with the construction drawings During installation, first spot weld a single corner code on the embedded parts according to the size line, and then check the position, size and verticality\r\n2. Aluminum panel curtain wall installation is installed according to the size number of the aluminum panel at the designed position, the width of the connection seam, horizontality, verticality and flatness of the plate. Should comply with specified requirements. Finally clean the seams and inject glue. \r\n3 Before installation, clean the dirt on the four sides of the aluminum plate to ensure reliable bonding of the embedded weather-resistant glue. \r\n4 The modules can only be installed after passing the self-inspection, mutual inspection and special inspection. \r\n5 After the aluminum plate is installed, cover the parts easily contaminated with plastic film for protection. Parts that are easily scratched or touched should be protected by safety railings. \r\n6 The gap between aluminum plates is generally 10 to 20mm, and should be treated with rubber strips or sealing elastic materials. \r\n7 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 of the grid joints and various indicators must be considered, and the error must be controlled within the range. \r\n2.\t Installation of columns and beams\r\n1. The installation size error of the entire wall vertical keel must be digested within the size range of the external control line, and the error must 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. \r\n2. After the vertical keel is installed, check the grid division. If it meets the specifications, install the transverse keel. The more accurate the transverse steel keel cutting size is, the better. If the gap is too large, cracks will occur during the welding process. Welding deformation affects the flatness of the entire curtain wall. \r\n2.3. After the horizontal materials are installed and spot welded, during the construction welding process, attention should be paid to the welding sequence (picture a), and the gap between the horizontal materials and vertical materials should be filled if it is too large (picture b). \r\n\r\n3． \tAfter the welding process is completed, conduct self-inspection to check the quality and geometric dimensions of the weld. If the self-inspection passes, fill in the concealment form and submit it to the supervisor for acceptance. After passing the inspection, the weld will be painted with a second coat of anti-rust paint. Carry out the next construction process. \r\n\r\n3.\tAluminum panel installation construction process and technical plan\r\n1. Process operation flow: Construction preparation → Inspect and accept aluminum panels → Aluminum panel maintenance → Stack aluminum panels according to installation locations → Preliminary Install → Adjust → Fix → Acceptance. \r\n2Basic operating instructions:\r\n2.1. Construction preparation: Since the installation of aluminum plate panels is the final step in the entire curtain wall installation, sufficient 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. The preparation of materials and tools is to check whether all the aluminum plates on the construction work surface are present and whether there are any absent or damaged plates. The preparation of the construction site is to check whether all the aluminum plates on the construction working surface are present and whether there are any absent or damaged aluminum plates. , the construction site preparation should leave enough space in the construction section to meet the installation needs. \r\n2.2. Inspection and acceptance of aluminum plates: \r\na.\tThe inspection contents include: \r\n (1) Whether the specifications and quantity are correct, and whether the color number is correct and intact; \r\n (2) Each Whether there are misaligned plates at the location;\r\n(3) Whether the stacking of aluminum plates is safe and reliable;\r\n(4) Whether there are aluminum plates with errors exceeding the standard;\r\n(5) Whether there are damaged aluminum plate panels. \r\nb.\tThe contents of the acceptance include: \r\n (1) Whether the three-dimensional error is within the control range; \r\n (2) Whether the aluminum plate pendant is damaged and needs to be replaced; \r\n (3) Sampling connection test. \r\nc.\tInspection and acceptance must be carefully recorded and bound into a book to sign the list of persons participating in the acceptance inspection. \r\n2.3. Aluminum plates are stacked according to number specifications: Before installing aluminum plates, the aluminum plates must be cleaned and stacked according to the installation location, and at the same time, they must be placed accurately in the order of installation numbers. The stacking should be appropriately tilted to prevent the aluminum plates from overturning.

\r\n2.4. Surface maintenance of aluminum panels:\r\nd.\tClean the surface of aluminum panels;\r\ne.\tRemove the protective packaging after the installation process is completed;\r\n2. 5. Initial installation: There are 4 to 6 people in each group during installation. The installation has the following steps: (installation from top to bottom from right)\r\nf.\tCheck to find the aluminum panel;\r\ng.\tTransport the aluminum panel; \r\nh.\tAdjust the direction;\r\ni.\tTransport the aluminum plate to the installation position;\r\n2.3. Install the aluminum plate according to the position of the numbered drawing. When installing the aluminum plate, pull the horizontal and vertical Vertical control line, because the entire steel frame is always somewhat uneven, the aluminum plate support points need to be adjusted and leveled. \r\n2.4. 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 flexural deformation of the aluminum plate (picture)\r\n\r\n2.5. Aluminum plate panel installation\r\nA.\tCheck, measure and adjust the horizontal and vertical connectors before installing the aluminum plate panel;\r\ nB.\tWhen installing, the deviation from left to right and up and down shall not be greater than 1.5mm;\r\nIV.\tGluing\r\nIt is difficult to glue the aluminum panel curtain wall with hidden glue seams, and special glue is required. Wear a ruler on the glue gun to ensure the glue thickness. \r\n1. 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 bars 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. \r\n\r\n2. After filling the foam strips, paste the masking paper. The masking paper should be pasted horizontally and vertically without any distortion. \r\n3. 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. \r\n3.1. When injecting glue into the glue seam, apply glue from bottom to top. Pay attention to the uniformity of the glue injection. After gluing, scraping and pressing the surface of the glue joint and trimming it smooth can overcome some blistering. What is more important is the proficiency and responsibility of the work operator. \r\n3.2. Inject glue on the west or north side of the building in the morning, and on the east or south side of the building in the afternoon. 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. \r\n3.3. When caulking the weather-resistant metal aluminum plate curtain wall, in hot summer, when the sun is exposed to the metal plate, 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. \r\n\r\nTianjin Dianjing Curtain Wall Decoration Engineering Co., Ltd.
