Construction method for closing outer steel and inner wood formworks in advance based on post-cast strip
The invention relates to the technical field of building construction, in particular to a construction method for closing an outer steel and inner wood formwork in advance based on a post-cast strip. The construction method comprises the steps that the embedded steel plates are arranged on the two sides of the post-cast strip; reinforcing steel bars are welded to the embedded steel plates; the pre-embedded steel plate is cleaned before the post-cast strip is closed; welding closed steel plates according to the sizes of the embedded steel plates; a formwork is erected on the inner side of the post-cast strip, and a batten secondary keel is arranged on the outer side of the post-cast strip. According to the technical scheme, steel plates are pre-embedded on the two sides of the outer side of the post-cast strip in advance, when the post-cast strip is closed in advance, the steel plates and the pre-embedded steel plates are welded to serve as an outer mold of the post-cast strip, a wood formwork is used as an inner mold, split bolts are welded to the outer steel plates in advance according to the reinforcing position of the inner mold, the inner mold is fixed through pulling, and a steel mold is used on the outer side; the post-cast strip formwork is simple in structure, high in rigidity and not prone to deformation, leakage risks are avoided, the post-cast strip formwork closing requirement is met, and the side pressure of backfill soil can be resisted.
本发明涉及建筑施工技术领域，尤其是涉及一种基于后浇带外钢内木模板提前封闭的施工方法。施工方法包括：在后浇带两侧设置预埋钢板；在预埋钢板上焊接钢筋；后浇带封闭前清理预埋钢板；根据预埋钢板尺寸焊接封闭钢板；所述后浇带的内侧支设模板，后浇带的外侧设置木方次龙骨。本发明的技术方案是在后浇带外侧两侧提前预埋钢板，后浇带提前封闭时钢板与预埋钢板焊接作为后浇带外模，内膜使用木模板，内模板根据加固位置提前在外钢板上焊接对拉螺栓，内模板通过拉结固定，外侧使用钢膜，刚度大、不易变形、避免了渗漏风险，既满足了后浇带模板封闭要求，又可以抵挡回填土的侧压力。
