Downward drainage and exhaust check valve for roof and drainage and exhaust method
The invention discloses a roof downward drainage and exhaust check valve and a drainage and exhaust method, and relates to the technical field of building roof secondary exhaust and drainage, the roof downward drainage and exhaust check valve comprises a steel bar truss floor support plate, an SBS waterproof roll is laid on the upper surface of the steel bar truss floor support plate, and an SBS waterproof roll and an extruded polystyrene board heat preservation layer are laid on the upper surface of the steel bar truss floor support plate; a metal siphon gutter inlet is formed in the steel bar truss floor support plate, a siphon rainwater main pipe is installed in the metal siphon gutter inlet, the top of the metal siphon gutter inlet is connected with a leaf stopper, a newly-added downward drainage and exhaust branch pipe is connected in the steel bar truss floor support plate, and the top of the newly-added downward drainage and exhaust branch pipe is also connected with a leaf stopper. A roof secondary drainage and exhaust check valve is arranged in an inner cavity of the newly-added downward drainage and exhaust branch pipe. The roof waterproof construction pain point of ultra-low energy consumption buildings with high roof waterproof requirements and public buildings with the waterproof grade of I is solved, the roof waterproof effectiveness of the buildings during the whole service life is ensured, the construction progress is accelerated, and the method has very high social and economic values.
本发明公开了一种屋面向下排水排气止回阀及排水排气方法，涉及建筑屋面二次排气排水技术领域，包括钢筋桁架楼承板，钢筋桁架楼承板的上表面铺设有SBS防水卷材、SBS防水卷材和挤塑聚苯板保温层，钢筋桁架楼承板内开设有金属虹吸雨水口，金属虹吸雨水口内安装有虹吸雨水主管，金属虹吸雨水口的顶部连接有挡叶器，钢筋桁架楼承板内连接有新增向下排水排气支管，且新增向下排水排气支管的顶部也连接有挡叶器，新增向下排水排气支管的内腔设有屋面二次排水排气止回阀。本发明解决了对屋面防水要求较高的超低能耗建筑和防水等级为Ⅰ级的公共建筑的屋面防水施工痛点，确保了建筑全寿命期间屋面防水有效性，加快了施工进度，具有很高的社会和经济价值。
