1. Before installing the color steel sandwich panel, the material, variety, size, performance, and core material of the color steel sandwich panel should be inspected, and the completed concealed work inside the color steel sandwich panel should be inspected to verify whether it meets the construction requirements.

2、安装彩钢夹芯板时，应检查过滤器、灯具、温度感烟元件、扬声器出风口及门窗、管道穿孔板。周围孔应平整、紧密、清洁、无尘。

2. When installing color steel sandwich panels, high-efficiency filters, lighting fixtures, temperature and smoke sensing components, speaker vents, doors and windows, and pipeline perforated panels should be inspected. The surrounding holes should be flat, tight, clean, and dust-free.

3、板与板缝应均匀，板缝间隙误差应不大于0.5mm，板缝涂密封胶均匀密封，密封处应平整、平整，略低于表面，墙板安装应垂直，瓦板安装应水平，板面平整，位置正确，墙与地面、墙与顶、顶与顶接缝应结构合理，保证密封，防止开裂，墙角应圆角。

3. The joints between boards should be uniform, and the gap error between boards should not exceed 0.5mm. The board joints should be evenly sealed with sealant, and the sealing area should be flat and even, slightly lower than the surface. The installation of wall panels should be vertical, the installation of tile panels should be horizontal, the board surface should be flat, and the position should be correct. The structure of the wall to ground, wall to top, and top to top joints should be reasonable to ensure sealing and prevent cracking. The wall corners should be rounded.

4、板材安装垂直度≤1.5mm，表面平整度≤1.5mm，板材与板材之差，接缝高度≤1.0mm，板材表面应平整、光滑、颜色均匀，板材表面保护膜应完好无损，交货前应将保护膜撕开，安装后应对板材进行保护，防止碰撞和损坏表面。

4. The perpendicularity of the board installation is ≤ 1.5mm, the surface flatness is ≤ 1.5mm, the difference between the board and the board, and the joint height is ≤ 1.0mm. The board surface should be flat, smooth, and of uniform color. The protective film on the board surface should be intact and undamaged before delivery. After installation, the board should be protected to prevent collision and surface damage.
