Continuous rigid frame bridge pier top detail structure capable of achieving simple support first and rigid frame second
The invention discloses a continuous rigid frame bridge pier top detail structure capable of achieving simple support first and rigid frame second, and relates to the technical field of continuous rigid frame bridges, the continuous rigid frame bridge pier top detail structure comprises a middle pier, concrete bases are arranged at the four corners of the upper end face of the middle pier, and a plurality of pier top extending steel bars are arranged on the upper end face of the middle pier along the edge and used for subsequent structure connection; main beams on the two sides are further included; the two main beams correspond to each other, a space is reserved between the two main beams, the space reserved between the two main beams and the middle pier forms an inverted T shape, and a cast-in-place section is formed; a plurality of longitudinal extending steel bars are arranged on the opposite sides of the two main beams; and a plurality of vertical extending steel bars are arranged on the lower end surfaces of the two main beams. The prefabricated steel structure has the beneficial effects that the main beam and the middle pier can be prefabricated in a prefabrication factory at the same time, whole-hole erection construction is conducted at the bridge site, through the inverted-T-shaped cast-in-place section, the cooperation with the steel beam mechanism, the vertical stretching-out steel bars and the pier top stretching-out steel bars, the structure is converted into a rigid frame system from a simply-supported system, and the overall mechanical property of the structure is remarkably improved.
本发明公开了一种可实现先简支后刚构的连续刚构桥墩顶细部构造，涉及连续刚构桥技术领域，包括：中墩，中墩上端面的四角处设置有混凝土底座，所述中墩的上端面沿边缘处设置有多个墩顶伸出钢筋，用于后续的结构连接；还包括两侧主梁；两个主梁相互对应，且之间留有空间，两个主梁与中墩之间留出的空间形成倒T字形，且形成现浇段；两个主梁相对的一侧设置有多个纵向伸出钢筋；两个所述主梁的下端面设置有多个竖向伸出钢筋。本发明的有益效果是：主梁和中墩能够同时在预制厂进行预制，在桥位整孔架设施工，通过倒T形现浇段，配合钢束机构、竖向伸出钢筋和墩顶伸出钢筋，使结构由简支体系转换为刚构体系，且结构整体力学性能显著提升。
