施工注意事项

undefined

                                                                                                                                
                ●                            卷材既可单独采用热熔法或冷粘法施工,也可采用冷热结合法即大面积用冷粘法,搭接缝部位用热熔的方法进行施工。            
                ●                            热熔法:用火焰喷枪或喷灯烘烤卷材底面和基层表面,使卷材表面的沥青熔化,边烘烤边向前滚铺卷材,随后用压辊滚压,使其与基层或卷材粘结牢固。            
                ●                            

                    冷粘法:先将胶粘剂均匀涂刷在防水基层和卷材上,稍加凉干后即可粘贴卷材,随后用压辊滚压,把卷材下面的空气挤出,使卷材平整,紧密,牢固地粘贴在基层或卷材上。

                                ●                                                            清理防水基层的施工工具:铁锹、扫帚、吹尘器、手锤、钢凿等。                            
                                ●                                                            卷材铺贴的施工工具:剪刀、卷尺、弹线盒、刮板、毛刷、压辊。                            
                                ●                                                            专用热熔机具:单头或多头热熔喷枪或喷灯。                            
                                ●                                                            辅料:基层处理剂、卷材胶粘剂、收口压条

                                ●                                                            施工前应将验收合格的基层清理干净,将棱角处的尘土吹净。                            
                                ●                                                            涂刷基层处理剂要均匀一致,切勿反复涂刷。                            
                                ●                                                            基层处理剂干燥后,首先按设计要求对屋面防水工程,地下防水工程需做附加层的部位进行铺设附加层处理。                            
                                ●                                                            确定卷材铺贴顺序和铺贴方向并在基层弹线,然后铺贴卷材,卷材不同部位的粘贴按以下要求施 工。
·屋面:卷材与基层点粘贴或条粘贴;屋面周边800mm应全粘贴;坡屋面粘贴面积在70%以上卷材与卷材间100%全粘贴;
·地下室底板:卷材与基层可全粘、点粘、条粘或空铺,但卷材与卷材之间必须全粘贴;
·地下室立墙:卷材与基层和卷材与卷材之间均应全粘贴;
·附加层:一般部位全粘贴,变形缝处允许空铺。                            
                                ●                                                            铺贴顺序为先高跨,后低跨;同等高度,先远后近;同一平面,从低处开始铺贴。                            
                                ●                                                            屋面铺贴方向:
·坡度<3%平行于屋脊方向铺贴。
·坡度3%~15%平行或垂直于屋脊方向铺贴。
·坡度>15%或受振动时宜垂直于屋脊方向铺贴。
·平行于屋脊搭接缝顺流水方向,垂直于屋脊时接缝应顺主导风向铺贴。

                                ●                                                            长边搭接:卷材纵向搭接宽度应≥80mm,必须仔细操作,涂刷胶粘剂要均匀,不得漏涂。冷粘法卷材边部应有多余的胶粘剂挤出。热熔法应在边部形成一道沥青条。                            
                                ●                                                            短边搭接:卷材两端必须全部粘结。搭接宽度应≥100mm,当用聚酯胎卷材点粘或空铺时,两头部分必须全粘500mm以上;冷粘法:接缝处应有胶粘剂挤出。 热熔法:接缝处要有沥青条挤出。                            
                                ●                                                            同一层相邻两幅卷材铺贴时,横向搭接边应错开1500mm以上,且上下两层卷材禁止互相垂直铺贴。                            
                                ●                                                            带页岩片卷材短边搭接时要去掉页岩层,方法是用火焰加热后用抹子刮掉页岩部分。也可以采用对接,方法是在接缝处下面垫300mm卷材条,卷材横向对接,接缝处用密封材料处理。                            
                                ●                                                            卷材铺贴完毕后,必须对搭接部位,端部及卷材收头部位进行密封处理。应嵌填密封材料,封口胶或冷粘剂,然后抹平,使其形成明显的沥青条。
