Construction method of smoke exhaust flue in high-rise building main body structure
The invention discloses a construction method of a smoke exhaust flue in a high-rise building main body structure. The problems that in the prior art, the construction cost is high, and the follow-up gap treatment procedure is tedious are solved. A reserved hole of a smoke and air pipeline on a floor plate is shrunk, when a lower end opening of a prefabricated finished smoke exhaust pipeline is in butt joint with the reserved hole, the reserved hole is located in the lower end opening of the prefabricated finished smoke exhaust pipeline, and a groove step is arranged on the lower bottom face of the floor plate outside the lower end opening of the reserved hole. The upper end opening of the prefabricated finished product smoke exhaust pipeline in the lower floor is embedded into the annular groove step, and communication between the prefabricated finished product smoke exhaust pipeline in the lower floor and the reserved hole is achieved; the structure is simple, the construction steps are few, the sealing effect of the flue gas duct is good, and the construction cost of the flue gas duct is greatly reduced.
本发明公开了一种高层建筑主体结构中的排烟气道的构筑方法，解决了现有技术存在的施工成本高和后续缝隙处理工序繁琐的问题；将楼层板上的烟风管道预留孔洞缩小，当预制成品排烟气管道的下端口对接在该预留孔洞上时，使预留孔洞位于预制成品排烟气管道的下端口内，在预留孔洞下端口外的楼层板下底面上设置凹槽台阶，使下层楼层内的预制成品排烟气管道的上端口嵌入到环形凹槽台阶中，实现下层楼层内的预制成品排烟气管道与预留孔洞的连通；本发明结构简单，施工步骤少，烟风道密封效果好，大大降低了烟风道的施工成本。
