Pre-tensioned prestressed frame assembly structure system and construction method thereof
The invention discloses a pre-tensioned prestressed frame assembly structure system and a construction method thereof. The pre-tensioned prestressed frame assembly structure system comprises a concrete column, a pre-tensioned prestressed thin-bottom laminated beam, a pre-tensioned prestressed thin-bottom laminated plate, a post-binding reinforcement cage and post-pouring concrete, the concrete column can be cast in place or prefabricated, and reinforcement and a post-pouring area are reserved at the position where the column is manufactured to a floor; the pre-tensioned prestressed thin-bottom superposed beam is composed of prestressed steel strands, a thin concrete beam bottom plate, stirrups and beam reinforcing ribs, the prestressed steel strands serve as partial stress longitudinal bars, non-prestressed steel bars are laid on the beam bottom plate and comprise bottom longitudinal steel bars, top longitudinal steel bars and the stirrups, the longitudinal steel bars are anchored into the concrete column, a standard anti-seismic requirement is met, and the overall performance and ductility of the structure are enhanced. According to the pre-tensioned prestressed frame assembly structure system, reinforcing steel bars perpendicular to reinforcing ribs are laid on the bottom plate of the pre-tensioned prestressed thin-bottom laminated plate, holes are reserved in the reinforcing ribs, the reinforcing steel bars can penetrate through the reinforcing ribs, the laminated floor slab can transfer force in two directions, and the structural integrity is comparable to that of cast-in-place.
本发明公开了一种先张预应力框架装配结构体系及其施工方法，其包括混凝土柱、先张预应力薄底叠合梁、先张预应力薄底叠合板、后扎钢筋骨架和后浇混凝土，其中，混凝土柱可为现浇或预制，柱制作至楼层处预留钢筋和后浇区域；所述先张预应力薄底叠合梁由预应力钢绞线、较薄混凝土梁底板、箍筋、梁加强肋组成，其中，预应力钢绞线作为部分受力纵筋，梁底板上铺设非预应力钢筋，非预应力钢筋包括底部和顶部纵向钢筋、箍筋，其中纵向钢筋锚入混凝土柱，满足规范抗震要求，增强结构整体性能和延性。本发明采用先张预应力薄底叠合板底板上铺设垂直于加强肋的钢筋，加强肋上留有孔洞，钢筋可以穿加强肋，叠合后楼板可以双向传力，结构整体性堪比现浇。
