When we carry out the construction of color steel tile roof, we must follow certain requirements to complete it to ensure the smooth completion of the construction. In the operation, we must master and understand some matters. Let's understand the following:

1、由于屋面坡度较大而且屋脊较多，在施工过程中对屋脊梁、檐口、老虎窗、汇（分）水线起止点等部位的标高必须精确控制；对于、坡度阴角线、坡度阳角线、檐口线、转角点、汇（分）水线起止点的定位必须精确；脚手架搭拆时应注意施工，并确保施工正常进行。

1. Since the roof slope is large and there are many ridges, the elevation of the roof ridge, cornice, dormer window, starting and ending points of the catchment (Branch) water line and other parts must be accurately controlled during the construction process; the positioning of the starting and ending points of the slope internal corner line, the slope external corner line, the cornice line, the corner point and the catchment (Branch) water line must be accurate; pay attention to the construction safety when erecting and removing the scaffold, and ensure the correct construction Regular progress.

2、屋面坡度较大，基层处理及挂瓦期间必须严格对工人做好技术交底，做好防护措施。

2. The roof slope is relatively large. During the base treatment and tile hanging, safety technical disclosure and safety protection measures must be made to the workers strictly.

3、严格控制好彩钢瓦的排列，阴角、阳角、端头瓦以及与出屋面构筑物交界处必须处理好，谨防漏水。

3. The arrangement of color steel tiles shall be strictly controlled. The internal corners, external corners, end tiles and the junction with the roof structure shall be handled well to prevent water leakage.

4、屋面周边和预留孔洞部位必须设置护栏和网或其他防止坠落的防护措施。

4. Safety guardrail and safety net or other protective measures against falling must be set around the roof and reserved holes.
