Assembled prestress progressive collapse preventing frame structure
The invention discloses an assembled prestress progressive collapse preventing frame structure. The assembled prestress progressive collapse preventing frame structure comprises a plurality of precastconcrete square columns, a plurality of reserved channels, a plurality of reserved holes, a plurality of precast concrete square beams, a plurality of beam longitudinal bars, a plurality of prestressed tendon channels, a plurality of lap-joint rebars, a plurality of prestressed tendons, a plurality of anchors, and a plurality of post-casting ultra-high-performance concrete zones; the precast concrete square columns and the precast concrete square beams are connected through the post-casting ultra-high-performance concrete zones; the lap-joint rebars penetrate through the reserved channels andthe post-casting ultra-high-performance concrete zones; the beam longitudinal bars and the lap-joint rebars are in lap joint in the post-casting ultra-high-performance concrete zones; and the prestressed tendons penetrate through the reserved holes, the post-casting ultra-high-performance concrete zones and the prestressed tendon channels and are anchored through the anchors. According to the assembled prestress progressive collapse preventing frame structure, through the prestressed tendons and ultra-high-performance concrete, when the frame structure collapses, cracking of tensile regions at ends of beams and pressed crisping of pressed zones are relieved, and accordingly, the progressive collapse preventing capacity of the structure is improved.
本发明公开一种装配式预应力抗连续倒塌框架结构,包括多个预制混凝土方柱、多个预留通道、多个预留孔洞、多个预制混凝土方梁、多根梁纵筋、多个预应力筋通道、多根搭接钢筋、多根预应力筋、多个锚具和多个后浇超高性能混凝土区域,预制混凝土方柱和预制混凝土方梁之间通过后浇超高性能混凝土区域连接,搭接钢筋穿过预留通道和后浇超高性能混凝土区域,梁纵筋与搭接钢筋在后浇超高性能混凝土区域搭接,预应力筋穿过预留孔洞、后浇超高性能混凝土区域和预应力筋通道并通过锚具锚固。本发明利用预应力筋和超高性能混凝土,在框架结构倒塌时,减缓梁端受拉区开裂和受压区域的压酥,进而提高结构抗连续倒塌能力。
