Construction method of roof cantilever modeling lightweight backfill structure
The invention relates to the field of building engineering roof overhanging modeling backfilling structures, in particular to a construction method of a roof overhanging modeling light-weight backfilling structure. Comprising the steps that a cantilever modeling structure base plane is cleaned up, and the whole is flat and free of protrusions and recesses; uniformly spraying cold primer oil on the base surface, and paving an SBS modified asphalt coiled material by adopting a hot melting method; the extruded polystyrene board is backfilled layer by layer, a prefabricated step is planned at a corner abutted seam formed by the backfilling cavity 301 and the polystyrene board 420, and the step 430 is filled with cement mortar with the ratio of 1: 3; 5 cm is reserved at the top, and C20 fine aggregate concrete and a reinforcing mesh are adopted for backfilling; the top face of the C20 fine aggregate concrete is evenly coated with JS-I type waterproof paint with the thickness of 1.5 mm; the extruded polystyrene board is adopted as a main material and has the advantages of being easy and convenient to construct, low in cost and the like, meanwhile, the two waterproof layers are additionally arranged, the probability that a concrete structure is damaged due to water seepage is reduced, and the reliability of the cantilever structure is higher.
本发明涉及建筑工程楼顶悬挑造型回填结构领域，具体涉及一种楼顶悬挑造型轻量化回填结构施工方法。包括将悬挑造型结构基面清理干净，整体平整无凸起凹陷；基面均匀喷洒冷底子油，再采用热熔法铺设SBS改性沥青卷材；分层回填挤塑聚苯板，在回填腔301与聚苯板420形成的边角拼缝处规划预制台阶，台阶430采用1:3水泥砂浆填实；顶部预留5cm采用C20细石混凝土+钢筋网片进行回填；C20细石混凝土顶面均匀涂刷1.5mm厚JS‑I型防水涂料；本发明主要材料采用挤塑聚苯板具有施工简便、成本低等优点，同时增设两道防水层，降低因渗水造成混凝土结构破坏的概率，使悬挑结构的可靠性更强。
