Roof doghouse opening SBS waterproof closing joint structure and construction method
The invention discloses a roof doghouse opening SBS waterproof closing joint structure and a construction method. The roof doghouse opening SBS waterproof closing joint structure comprises a doghouse wall; the ventilation pipe is arranged on the doghouse hole of the wall body in a penetrating manner, a gap is formed between the ventilation pipe and the doghouse hole, and the gap is filled with a rock wool layer; the metal edge folding piece comprises an upper edge folding section, a middle inclined section and a lower edge folding section which are integrally connected in sequence, the upper edge folding section is fixedly lapped on the outer wall of the doghouse wall body, and the lower edge folding section is lapped on the outer pipe wall of the ventilation pipe; and the SBS waterproof coiled material layer is laid on the metal edge folding piece and matched with the metal edge folding piece in shape, and a liquid waterproof coiled material layer is painted at the joint of the lower side edge of the SBS waterproof coiled material layer and the ventilation pipe. The node is good in waterproof effect, the rock wool layer can reduce the influence of vibration generated when the ventilation pipe works on the closing-up node to the minimum, and meanwhile it is guaranteed that heat preservation of the wall of the doghouse is continuous and free of breakpoints; due to the middle inclined section of the metal edge folding piece, the phenomenon that hollowing is prone to occurring at the transfer position due to the fact that the SBS waterproof roll layer is too hard is avoided.
本发明公开了一种屋面狗屋洞口SBS防水收口节点结构及施工方法，包括：狗屋墙体；通风管，其穿设在墙体的狗屋洞口上，且二者之间有缝隙，缝隙内填充塞实有岩棉层；金属折边件，其包括：一体依次连接的上折边段、中间倾斜段和下折边段，上折边段搭固在狗屋墙体的外墙壁上，下折边段搭接在通风管外管壁上；SBS防水卷材层，其铺设在金属折边件上，且与金属折边件形状适配，SBS防水卷材层的下侧边沿与通风管交接位置处涂刷有液态防水卷材层。该节点防水效果好，且岩棉层可将通风管工作时产生的震动对该收口节点的影响降到最低，同时确保狗屋墙体保温连续无断点；金属折边件的中间倾斜段避免了SBS防水卷材层因过硬导致转交处易出现空鼓的现象。
