border-radius: 0px; transform: none; transition: none 0s ease 0s; box-sizing: border-box; font-size: 16px;">　　2、预铺TPO防水卷材：把TPO防水卷材按弹线控制位置布置在基层上，卷材平整顺直，不得扭曲，搭接宽度100mm，并进行适当的剪裁。</span></p><p class="p2" style="margin-top: 0px;

transition: none 0s ease 0s; box-sizing: border-box; font-size: 16px;">　　4、节点处理：裁剪适合相应节点的卷材片材，采用手持式焊枪将片材焊接于大面卷材上。</span></p><p class="p2" style="margin-top: 0px; margin-bottom: 0px; padding: 0px; border: 0px;

border-radius: 0px; transform: none; transition: none 0s ease 0s; box-sizing: border-box; font-size: 16px;">　　7、解决这一问题的办法无非是提高卷材的延伸率，减少结构变形和改变铺贴工艺，而改变铺贴施工工艺*为简便易行。空铺法、点粘法、条粘法和机械固定法等工艺使防水层与基层尽量脱开，防水层有足够的长度参加应变，对解决防水层被拉裂起到了良好的效果。</span></p>
