UHPC-steel bar reinforced pier capping beam structure and reinforcing method
The invention discloses a UHPC-steel bar reinforced bridge pier cover beam structure and a reinforcing method, and belongs to the technical field of bridge reinforcement. The UHPC-steel bar reinforced bridge pier cover beam structure comprises a plurality of transverse embedded steel bars which are located on the two side faces of an original cover beam and arranged at intervals in the transverse direction of the original cover beam; the longitudinal embedded steel bars are located on the two end faces of the original bent cap and arranged at intervals in the longitudinal direction of the original bent cap. The transverse stress main ribs are arranged on the upper side of the original bent cap at intervals in the longitudinal direction of the original bent cap. The multiple inverted-U-shaped stirrups are arranged at intervals in the transverse direction of the original bent cap. The longitudinal embedded steel bars, the transverse embedded steel bars, the inverted-U-shaped stirrups and the transverse stress main steel bars are all connected with a main body framework of an original bent cap to form a widened part of the original bent cap. And the UHPC concrete layer is poured on the widened part of the original bent cap. As the section size of the pier capping beam is increased, the problem that the capping beam cannot meet the requirement of a new anti-seismic specification for the minimum distance from the beam end to the edge of the capping beam is solved.
本发明公开了一种UHPC‑钢筋加固桥墩盖梁结构及加固方法，属于桥梁加固技术领域，其包括多根横向植筋位于原有盖梁的两侧面,并沿原有盖梁的横向方向间隔设置；多根纵向植筋位于原有盖梁的两端面，并沿原有盖梁的纵向方向间隔设置；多根横向受力主筋沿原有盖梁的纵向方向间隔设置于原有盖梁的上侧；多根倒U型箍筋沿原有盖梁的横向间隔设置；其中，纵向植筋、横向植筋、倒U型箍筋和横向受力主筋均与原有盖梁的主体骨架连接以形成原有盖梁的加宽部分；UHPC混凝土层浇筑于原有盖梁的加宽部分。本发明由于桥墩盖梁截面尺寸的增大，解决了盖梁不满足新抗震规范对梁端到盖梁边缘最小距离要求的问题。
