Description

一种半装配式桥墩耗能系梁结构A semi-fabricated bridge pier energy dissipation tie beam structure

技术领域technical field

本实用新型涉及桥梁工程技术领域，具体涉及一种半装配式桥墩耗能系梁结构。The utility model relates to the technical field of bridge engineering, in particular to a semi-assembled bridge pier energy dissipation tie beam structure.

背景技术Background technique

桥梁桥梁高桥墩混凝土系梁刚度较大，在发生地震时，往往由于混凝土系梁刚度大、耗能能力弱，导致墩柱、系梁同时出现破坏，且难以修复。采用钢材作为模板的整体现浇施工方法时，钢模板数量巨大，而采用全截面预制拼装的施工方法，桥墩和系梁之间不好连接，并且需要大型吊装设备、运输设备和预制场地等。这两种施工方法都存在施工难、费用高与工效低等不足。The rigidity of the concrete tie beams of the high piers of bridges and bridges is relatively large. In the event of an earthquake, the pier columns and the tie beams are damaged at the same time due to the high rigidity and weak energy dissipation capacity of the concrete tie beams, which are difficult to repair. When using steel as the overall cast-in-place construction method of the formwork, the number of steel formwork is huge, while the construction method of full-section prefabricated assembly is not easy to connect the bridge pier and the tie beam, and requires large hoisting equipment, transportation equipment and prefabricated site.
