Large-span hinged rotary consolidation steel bent cap and construction method
The invention discloses a large-span hinged-to-fixed steel cover beam and a construction method, and relates to the field of bridge structures, the large-span hinged-to-fixed steel cover beam comprises a steel cover beam and a bridge pier, the steel cover beam and the bridge pier are connected in advance through a plurality of hinged structures, and pouring spaces are formed on the two sides of each hinged structure through symmetrical fixing plates; after the bridge is formed, the pouring space is filled with concrete so that the steel cover beam can be fixedly connected with the bridge pier. In the construction process, the steel cover beam and the bridge pier are firstly hinged and then solidified after the bridge is formed, the bridge pier only bears bending moment generated by live load, the stress of the bridge pier is definite, and the structural size and the section reinforcement ratio of the bridge pier are reduced.
本发明公开了一种大跨径铰接转固结钢盖梁及施工方法，涉及桥梁结构领域，包括钢盖梁、桥墩，钢盖梁和桥墩之间预先通过若干铰接构造连接，铰接构造两侧通过对称的固定板件形成浇筑空间，成桥后在浇筑空间内填充混凝土以使钢盖梁与桥墩固结。本发明施工过程中钢盖梁与桥墩先铰接，成桥后再固结，桥墩仅承受活载产生的弯矩，桥墩受力明确，减小桥墩结构尺寸及截面配筋率。
