Construction steps of aluminum plate dry hanging wall surface of external wall

Exterior wall decoration is an important part of decoration engineering. Due to the harsh environment such as long-term wind, rain and sun, the "damage and erosion" of the outer wall far exceeds that of the inner wall. Therefore, it is particularly important to choose suitable materials and strict construction for exterior wall decoration. Among many tools, aluminum plate dry-hung wall has been widely used for its unique advantages. This paper will introduce the construction steps of aluminum plate dry hanging wall for you.

Measuring unreeling

Ensure that the wind power in the surrounding environment does not exceed Grade 4, accurately project all embedded parts onto the main structure, and retest the dimensions. After the elastic line is completed, it must be carefully checked to ensure the correct height and position.

Installing connector

The connector is fixed to the embedded part of the main structure by welding. When the embedded iron parts are not embedded in the main structure, they can be fixed with expansion bolts and further fixed with connecting iron.

Mounting skeleton

Weld or bolt the vertical skeleton coated with anticorrosive paint to the connector according to the pre-played lines. In the installation process, be sure to check the height, centerline position, verticality and flatness of the skeleton column at any time.

Installing aluminum plate

Fix the aluminum-plastic plates on the steel frame one by one, and note that there is a gap of 10- 15mm between the plates to facilitate subsequent adjustment. During installation, ensure that the horizontal and vertical displacement does not exceed1.5mm. ..

Gap handling and bridging

Immediately after cleaning the surface and frame of aluminum-plastic plate, place sealing strip or sealing strip between aluminum plates, and inject silicone weatherproof sealant. Finally, the wallboard and keel are covered with metal plates to complete the overall construction of aluminum plate dry hanging wall surface.
