铺贴卷材用搭接法，上下层及相邻两幅卷材搭接缝应错开，搭接宽度应满足设计

Lap joints are used for laying coils. The lap joints of the upper and lower layers and the adjacent two coils should be staggered, and the width of the laps should meet the requirements of the design and acceptance specifications. The construction of the coil roof joints is very important. During the construction, we should refer to the conventional methods under the conditions of the design, not only to ensure the quality, but also to facilitate the construction, the principle of first high and then low.

Spreading coils with a tying method, upper and lower layers and adjacent two coil seams should be staggered, mating width should meet the design and acceptance specifications. The construction of the coil roof node is very important, the construction should refer to the conventional practice under the conditions allowed by the design, not only to ensure the quality, but also to facilitate the construction, first high and then low principle.
