一种虹吸式落水口防水节点结构
本技术涉及建筑防水领域,尤其涉及一种虹吸式落水口防水节点结构。
技术介绍
为了保证屋面的排水系统正常工作,往往会在屋面上设置落水口,而落水口处是屋面最容易出现渗漏的地方,传统作法的缺点是:只要水流稍大,水就会从粘结不牢的卷材底下进入墙体内,造成屋面渗漏,为消除此处渗漏,因此需要对传统作法进行改进。
技术实现思路
本技术的目的在于针对现有技术的缺陷和不足,提供一种虹吸式落水口防水节点结构,该防水结构设计合理,采用自粘SBS改性沥青隔汽层与TPO防水卷材层形成整体的密封防水系统,且材料耐久,使用寿命长,维护成本低。为实现上述目的,本技术采用的技术方案是:一种虹吸式落水口防水节点结构,包括有落水口、虹吸雨水斗、镀铝锌钢承板、隔汽层、密封胶体、岩棉保温板、防水卷材层、环形法兰片、密封胶层;所述镀铝锌钢承板为设于落水口周边底部的加固结构;所述虹吸雨水斗设于落水口上端口,该虹吸雨水斗分为头部和斗体,所述斗体置于落水口内;所述隔汽层铺设于镀铝锌钢承板上,该隔汽层与落水口交界处设置有密封胶体;所述岩棉保温板设置于隔汽层上;所述防水卷材层分为平面式防水卷材层和环绕式防水卷材层,所述平面式防水卷材层铺设于岩棉保温板上并延伸至落水口上端部,由环形法兰片和螺栓压紧固定,并同时在平面式防水卷材层与螺栓交界处周边设置有密封胶层;所述环绕式防水卷材层环绕铺设于虹吸雨水斗的斗体周边,该环绕式防水卷材层铺设至落水口上端部时,与平面式防水卷材层通过热风焊接固定。作为优选,所述隔汽层为自粘型SBS改性沥青隔汽层。作为优选,所述防水卷材层均为TPO防水卷材层,环绕式防水卷材 ...
