1彩涂压型钢板的选择应考虑屋面坡度。当坡度较小时，可能导致屋顶区域积水。因此，高波纹彩涂压型钢板是首选。
2彩涂压型钢板腹板与翼缘水平面夹角不应小于。
三。彩涂压型钢板宜采用长板，尽量不采用横向搭接，有利于屋面防水
4严格按照型钢的搭接长度与型钢搭接进行可靠连接。彩涂压型钢板必须大于70mm，长度必须大于350mm，波高小于70mm的低波纹彩涂压型钢板搭接长度不小于250mm，搭接处必须涂密封胶带。
5彩涂压型钢板侧面连接方式有多种。详见本章第4节。为防止屋面漏水，尽可能采用暗装连接。屋面板横向搭接时，搭接宽度应根据彩涂压型钢板的形状和规格确定，一般不小于半波，搭接方向应与主导风向一致。波高小于70mm的低波纹彩涂压型钢板不需要固定支架，波高大于70mm的波纹彩涂压型钢板应设置固定支架。
彩涂压型钢板的横向和横向连接必须可靠，防止屋面板错位和滑动。
⒎考虑到内密封材料性能较差，易老化开裂，施工时接头应尽量设置在波峰处，以防进水。

1. The selection of color coated profiled steel sheet should consider the roof slope. When the slope is small, it may lead to water in the roof area. Therefore, the color coated profiled steel sheet with high ripple is one of the first choices.

2. The included angle between the web plate of color coated profiled steel sheet and the horizontal surface of flange should not be less than.
3. Color coated profiled steel sheet should be long-length plate, and it is better not to use transverse lap as far as possible, which is conducive to roof waterproof
4. The transverse lap of color coated profiled steel sheet shall be reliably connected with purlin, and the length shall be strictly implemented in accordance with the specifications. The color coated profiled steel sheet must be greater than 70mm, the length must be greater than 350mm, and the low ripple color coated profiled steel sheet with wave height less than 70mm should have the lap length not be less than 250mm, and the lap joint must be coated with sealing tape.
5. There are different ways of side connection of color coated profiled steel sheet. See section 4 of this chapter for details. In order to prevent water leakage from the roof, concealed connection shall be adopted as far as possible if possible. When the roof panel is laterally overlapped, the lap width shall be determined according to the shape and specification of color coated profiled steel sheet, and generally not less than half wave, and the lapping direction shall be consistent with the dominant wind direction. For low ripple color coated profiled steel sheet with wave height less than 70mm, fixed bracket is not required, while for corrugated color coated profiled steel sheet with wave height greater than 70mm, fixed support shall be provided.
The transverse and lateral connection of the color coated profiled steel sheet must be reliable, so as to prevent the dislocation and sliding of the roof panel.
⒎ in consideration of the poor performance of domestic sealing materials and easy to aging and cracking, the connectors shall be set at the wave crest as far as possible during construction, so as to prevent water.
