Different installation units have different installation methods for aluminum veneers. The installation methods and precautions for aluminum veneers are as follows:

Installation methods for aluminum veneers:

1. Transport the aluminum plates and accessories to each construction site using vertical transportation equipment such as elevators.

2. Use detergent to clean the indoor side of the aluminum plate and the surface of the column frame.

3. The entire aluminum plate is connected to the keel through the surrounding aluminum corner codes (hanging lugs) and fixed on the keel.

4. Fixing method. If the interior is seamlessly spliced, you can use an electric drill to drill holes on the keel at the corresponding position, and then rivet it with flat-head (countersunk head) aluminum rivets; if it is a board with glue seams on the exterior, Steel swivel screws (also called flange screws or phoenix tail nails, see the picture) can be drilled directly into the keel through the connecting holes of the aluminum corner codes to fix the aluminum plate, but attention should be paid to controlling the tightness of the drill bit to adjust the aluminum plate.

5. The aluminum plate is brought into the site for trial assembly. First, fix the aluminum plate slightly on the keel, pay attention to the installation accuracy control, and adjust the plate before tightening.

6. When installing aluminum plates, install them on the wall in sequence according to the number of the aluminum plates.

7. The installation of aluminum plates should start from the front, large areas, and corners, and install from top to bottom.

8. The connection between the aluminum plate and the keel must comply with the requirements of the drawings and must be strong and reliable, and bolts must be installed.

9. The connection structure of the corners of the curtain wall and surrounding walls, the upper and lower seals, and the treatment of deformation joints should meet the design requirements.

10. Node structure and closing treatment

① Wall panel joints: Usually uneven top and bottom or unequal board surfaces are prone to occur at the joints of joints, so one should first be Install the side panels, position the line, and use horizontal and vertical control lines to determine the installation position of the other side panel. After both sides of the panels meet the requirements, pull out the rivets in turn and install the pressure plate to fix;

②Wall The lower end of the surface is closed, and a special water retaining plate is made according to the actual size to seal the lower end. At the same time, the gap between the plate and the wall is covered to prevent rainwater from seeping into the room;

11. Pay attention to the space between the plates during installation Gaps and height requirements for panel interfaces

12. After the aluminum plate is installed, cover and protect the parts that are easily contaminated with plastic film or other materials.

Precautions for the preparation of aluminum veneer installation and construction:

1. Check the construction drawings and on-site measured dimensions in detail to ensure the perfection of the in-depth design and processing, and carefully compare it with the structural node diagram Check and find any inconsistencies and correct the design as soon as possible.

2. Check whether the quality of the horizontal and vertical keels meets the drawing requirements. The installation of horizontal and vertical keels complies with the design specifications. The connecting bolts for horizontal and vertical keel installation must not be missed. In order to ensure the installation accuracy of the board, it is advisable to use theodolite to penetrate the beams and mullions. Deformation joints, settlement joints, variable cross-sections, etc. should be properly handled to ensure that they meet the usage requirements.

3. The material and processing geometric dimensions of metal connectors must meet the design requirements, and the materials must have factory certificates and retest reports.

4. The connection between the connecting piece and the vertical keel must be reliable, and do not miss the elastic pad.

5. Check the aluminum plate material, plate color, strength, appearance, processing accuracy, etc. to see if it meets the design and national standards.

(1) Check the processing accuracy such as length and width deviation, diagonal size difference, and parallelism deviation of the aluminum plate: the processing accuracy requirements of the aluminum veneer are all in accordance with standards that are much higher than the national standards. The company's standards are implemented.

(2) Check the flatness of the aluminum plate surface: Use a 3m ruler to check the flatness of the aluminum plate surface, and the allowable deviation is 3mm. Use a 3m ruler to check the board's verticality and level, with an allowable deviation of 2.5mm. Use a square ruler to check the yin and yang angles, with an allowable deviation of 2.5mm.

(3) Check the folding angle of the aluminum plate and the angle deviation of the multi-folded plate: it must be within ±0.50, the fillet radius of the aluminum plate folding meets the design requirements, and the folding is formed in one go.

(4) The riveting lugs on the folded edge of the board are in the correct position.

(5) The surface of the provided processed and formed plates shall not have obvious indentations, prints, dents and other residues, and there shall be no damage, hidden damage or markings on the surface of the plate.

(6) The nails used to connect the ribs and the back of the aluminum plate should not have obvious bulges or depressions on the surface of the aluminum plate after the nailing is completed, and the coating surface should not produce phenomena that affect the look and feel, and should be firmly fixed.

(7) Aluminum plates should be marked according to the requirements of the design drawings.

6. The plates enter the site and are stacked according to specification numbers to prevent collision and pollution.

7. Scaffolding must be set up before installation and construction, and the hanging basket for installation operation must be inspected and accepted by the relevant departments. Check whether the scaffolding meets curtain wall construction and specification requirements.

After a series of steps are completed, the installation task is completed.
