Construction method of waterproof, unloading and smoke mixing prevention integrated indoor exhaust duct structure
The invention discloses a construction method of a waterproof, unloading and smoke mixing prevention integrated indoor exhaust duct structure, which comprises the following steps of: 1, preparing a connecting pipe hoop which is made of a flame-retardant soft PVC (Polyvinyl Chloride) material; secondly, a bell mouth of each connecting pipe hoop is hooped and sleeved on an upper opening of one flue located below the connecting pipe hoop, and a lower opening of one flue located above the connecting pipe hoop is inserted into an inserting opening of each connecting pipe hoop; the fixing steel bars on each connecting pipe hoop are fixedly connected with reserved stressed steel bars at the positions of floor slabs of all floors and a floor structural slab of a first kitchen or toilet, and non-shrinkage anti-seepage concrete is poured in reserved flue openings outside all the flues. By the adoption of the method, the flue is prevented from generating accumulated loads, and it is guaranteed that the lower-layer flue is not pressed and damaged due to weight transfer of the upper-layer flue.
本发明公开了防水、卸载、防串烟一体化室内排风道结构的施工方法，包括以下步骤：第一步，准备连接管箍，所述的连接管箍为阻燃软质PVC材料；第二步，每一个连接管箍的承口分别箍套在位于连接管箍下方的一根烟道的上口上并且在每一个连接管箍的插口内分别插有位于连接管箍上方的一根烟道的下口,每一个连接管箍上的固定钢筋分别与各层楼板以及第一层厨房或者卫生间地面结构板处的预留受力钢筋接固定，在各个烟道外的预留烟道口内浇筑有无收缩抗渗混凝。采用本方法避免了烟道产生堆积荷载，保证了下层烟道不因上层烟道重量的传递造成受压破损。
