Exterior wall decoration is also a very important part of decoration engineering. The exterior wall has been subjected to all kinds of "destruction and erosion" far greater than the interior wall, and it has been exposed to wind, sun and rain all the year round, so the decoration of the exterior wall, whether it is material or construction, has become very critical. At present, there are abundant materials for exterior wall decoration, such as exterior wall bricks, dry hanging boards, marble, real stone paint and so on. In many tooling, aluminum plates are used for dry hanging on the wall, so what are the specific construction steps?

1. Measure the wind force of the surrounding environment when the pay-off aluminum plate is hung on the wall to bounce the line. According to the design requirements, the installation position line of the support frame is accurately projected on the main structure, and all the embedded parts are punched and re-measured. After the thread is bounced, it should be rechecked immediately to ensure that there is no problem with the height and position.

Secondly, the connector for installing the aluminum plate dry-hung wall surface is fixed on the embedded part of the main structure by welding. When the embedded iron pieces are not embedded in the main structure, the expansion bolts can be fixed on the main structure and fixed by the connecting iron.

Third, install the skeleton aluminum plate to dry hang the wall surface. Third, according to the elastic line position in the first step, fix the vertical skeleton coated with anticorrosive paint on the connector by welding or bolts. During installation, check the height and center line position of the skeleton column of large-area and high-height aluminum frame curtain wall at any time, and ensure the verticality and flatness of the skeleton vertical with measuring instruments and wire pendants.

Iv. Installing aluminum plates and aluminum plate dry-hung walls The fourth step is to install aluminum-plastic plates, and fix them on the steel frame one by one. Pay attention to the gap between plates as 10 to 15 mm, so as to facilitate adjustment if there is any error in the installation process. When installing aluminum-plastic plate, ensure that the horizontal and vertical displacement does not exceed 1.5? Hmm.

Verb (abbreviation of verb) Gap treatment and sealing aluminum plate Dry-hung wall After aluminum plate is installed, clean the surface and frame of aluminum-plastic plate, then immediately place sealing strip or weather-resistant strip in the gap between aluminum plates, and then inject silicone weather-resistant sealant. Aluminum plate closing can cover the wallboard and keel with metal plate, and the aluminum plate dry hanging wall basically ends here.

Aluminum plate dry-hung walls are widely used in the external walls of many public buildings, and the construction technology is similar, but the decoration of the external walls is not only technology, but also safety issues. External wall climbing is very common, and the height is relatively high, so besides ensuring the quality, we should also pay attention to the safety of construction.
