Longitudinal assembly type prestressed bent cap
The invention discloses a longitudinal assembly type prestressed bent cap which comprises two prestressed bent cap prefabricated assemblies symmetrically arranged in the longitudinal length directionof the bent cap. Pier column main reinforcement preformed holes are formed in the range of a pier column top joint area of the assembly. Transverse prestressed ducts are formed in the side faces of the assemblies; the overhanging parts of the assemblies are C-shaped sections; transverse partition plates are arranged in the C-shaped sections; transverse prestressed ducts are reserved in the transverse partition plates; transverse prestressed steel bar assemblies tension and fix the two symmetrically-arranged assemblies through the prestressed ducts; and a post-cast strip is arranged at the abutted seam position of the two assemblies. The bent cap has the advantages that the abutted seams are arranged in the longitudinal length direction of the bent cap, internal force in the direction is small, structural weak areas are avoided, the transverse prestressed reinforcements provide a concrete hooping effect, structural bearing capacity and anti-seismic property are improved, and structuralsafety of the bent cap is guaranteed. The overhanging part of the assembly is a C-shaped section, so that a cavity is formed in the bent cap after the assemblies are symmetrically assembled, the selfweight of the bent cap body is greatly reduced, the hoisting batch is reduced, and the hoisting cost is saved.
本发明公开一种纵向装配式预应力盖梁，包括，沿盖梁纵长度方向对称布置的两座预应力盖梁预制组件；组件在墩柱顶部节点域范围内设有墩柱主筋预留孔，组件的侧面设有横向预应力孔道，组件悬挑部分为C型截面，C型截面范围内设有横隔板，横隔板上预留横向预应力孔道，横向预应力钢筋组件通过预应力孔道将对称布置的两座组件拉紧固定，两座组件拼缝位置设有后浇带。有益效果是，拼缝沿梁纵长度方向设置，该方向内力较小，避免产生结构薄弱区，横向预应力钢筋提供混凝土套箍作用，提高结构承载能力和抗震性能，保证盖梁结构安全。组件在悬挑部分为C型截面，使组件对称拼装后盖梁内部形成空腔，大幅降低梁体自重，减少吊装批次，节约吊装费用。
