How to carry out enclosure construction of color steel plate building

1. Before installation, the installation position of color steel plate shall be marked on the cylinder. At the same time, the top surface of foundation (ground beam) shall be set with 1: 3 cement mortar or fine stones.

The soil is flat.

2. When installing the first color steel plate, cement mortar with a thickness of 20mm 1: 3 should be used, the elevation should be controlled with a wooden wedge, and the joints should be embedded with 1:3 cement mortar.

3. In addition, after the color steel plate is leveled and straightened, both ends of the top surface shall be fixed by stainless steel connectors or rust-proof steel plates with a thickness of not less than 4 mm.. The other end of the connector should be connected with the concrete embedded parts or hooked on the flange of the steel column.

4. Secondly, the joints at both ends between the plate joints should be coated with adhesive. Every five transverse plates are supported by angle steel with the thickness of 10 mm, one limb of the angle steel is welded with concrete embedded parts or steel cylinders, and the other limb is fixed with hollow nails.

5. The top skin of each wallboard or the external wall panel of the whole room floor should be embedded with homogeneous sand aerated concrete blocks, and the fixing method of the blocks can be constructed according to the Code for Construction and Acceptance of Yitong Light Sand Aerated Concrete Block Engineering: when color steel plates are used, bolts should be used to fix them with the structure.

6. In addition, the seam between the color steel plate and the foundation and the flat-fell seam between the color steel plates shall be sealed with sealant. The width of the end seam should be 10 ~ 15 mm, and the seam should be filled with glass wool or rock wool, and then sealed with sealant after embedding PE rods.
