防水卷材铺贴的施工要点：
Key points of waterproof roll-up construction:
（1）卷材防水层施工应在砌筑、安装设备、管道等完工后进行。
(1) The construction of coil waterproofing layer shall be carried out after the completion of masonry, installation equipment and pipelines.
（2）铺贴高低跨的房屋时，应按先高后低，先远后近的顺序进行。
(2) When laying high and low span houses, they should be arranged in the order of height first, then low, and distance first.
（3）在一个单跨铺贴时，应先铺贴排水比较集中的部位（如落水口、檐口、斜沟、天沟等处），按标高做到由低到高，坡面与立面的卷材应由下开始向上铺贴，使卷材按水流方向搭接。
(3) In a single-span paving, the more concentrated drainage areas (such as falling water, eaves, inclined ditches, gutters, etc.) should be laid first, from low to high according to the elevation, and the coils on the slope and elevation should be laid upward from bottom to make the coils overlap in the direction of water flow.
（4）卷材平行屋脊铺贴时，长边搭接不小于70mm，短边不小于150mm，相邻两幅卷材短边搭接缝应错开不小于500mm，为保保定平面设计培训 保定空调维修 保定管道通风 包装盒定做 化粪池模具 废旧电缆回收 不锈钢铸件 证卷材搭接宽度和铺贴顺直，铺贴卷材时应弹出标线。
(4) When laying coil parallel roof, the overlap of long side is not less than 70 mm, the overlap of short side is not less than 150 mm, and the overlap joint of short side of two adjacent coils should be staggered not less than 500 mm. In order to ensure the overlap width and straightness of coil laying, the labeling line should be ejected when laying coil.
（5）坡度超过25%的拱形屋面和天窗下的坡面上，应尽量避免短边搭接。
(5) Short side overlap should be avoided as far as possible on arch roofs with slopes over 25% and slopes under skylights.
（6）卷材铺贴前，找平层应干燥，一般现场试验的方法：由傍晚至次日晨或在晴天约1—2h内，铺盖1m2卷材，如卷材内侧无结露时即认为找平层已基本干燥。
(6) Before coil laying, the leveling layer should be dried. The general method of field test is to lay 1 m2 coil from evening to the next morning or within 1-2 hours of sunny day. If there is no condensation inside the coil, it is considered that the leveling layer has been basically dried.
