Aluminum composite panel seam treatment method

Aluminum composite panel seam treatment method

The joint treatment of aluminum composite panels can be summarized into two categories, one is to hide the fixed point, and the other is to expose the fixed point.

1. Preliminary work:

(1). First check the quality of the skeleton, focus on checking the straightness of the boom, the force is even, and the distance between the keels does not exceed 500mm. If it is a humid environment, the design requires that the distance be appropriately reduced, the lower surface of the keel is smooth without falling feeling, and the main accessories are tightly connected. Only firm and qualified can be restrained. The cutting of the board should be broken along the cutting, so that the edge of the cutting board is straight, square and free of defects such as missing corners.

(2). When the board is fixed, lay one side (edge surface) of the aluminum-plastic board perpendicular to the supporting keel, and there must be a hanging phenomenon in the lower right corner. Aluminum-plastic panels should be tightly butted, but not forcibly fixed. They can start in a corner or in the middle row. They should not be laid at the same time. Seams should be straight, with the same width and width, and there should be no wrong seams.

(3). When jointing, the aluminum composite panels must be tightly butted, but cannot be pressed in place, the butt joints must be staggered, and the joints on both sides of the wall must not fall on the same keel; Falling on the same vertical keel, the double-layer plasterboard should be staggered.

2. Fixed-point hiding method:

(1). Use sealing materials such as glue or rubber for concealment;

(2). Cover with frame aluminum profile or decorative aluminum profile;

(3). After folding the aluminum composite panel, place the fixing points inside.

3. Fixed-point exposure method:

(1). Use aluminum profiles to wrap the edges or directly cover the seams;

(2). Cover the seams with adhesive strips, directly exposing the fixing screws or rivets;

(3). In addition to the use of rubber, exposed fixings or aluminium profiles must be surface treated, such as lacquered.
