Unconstrained bridge side span closure device and closure method
The invention discloses an unconstrained bridge side span closure device and method. The device comprises a formwork support system which is a support system for side span closure section construction, a sliding system which comprises an upper-layer structure and a lower-layer structure and is a key system for realizing unconstrained closure, an anchoring reinforcing system which is anchored to the last section of a main beam cantilever section to improve the bearing capacity of the formwork support system, an end formwork pre-tightening system which is a formwork pre-tightening system during closure section construction, and a support system which is a permanent bridge support. According to the unconstrained bridge side span closure device and method, the structure is simple, implementation is convenient, on the premise that the bridge side span closure quality is guaranteed, compared with a conventional side span closure scheme, a bridge side span temporary consolidation system is omitted, the construction cost is reduced, the construction efficiency is improved, and the device and the method can be widely applied to the technical field of bridge side span closure construction.
本发明公开了一种无约束桥梁边跨合龙装置及合龙方法，包括：模板支架系统，其为边跨合龙段施工的支撑体系；滑移系统，其包括上下两层结构，为实现无约束合龙的关键体系；锚固加强系统，其锚固于主梁悬臂节段最后一节，增加所述模板支架系统的承载能力；端模预紧系统，其为合龙段施工时的模板预紧体系；支座系统，其为桥梁永久支座。本发明提供一种无约束桥梁边跨合龙装置及合龙方法，其结构简单、便于实施，在确保桥梁边跨合龙质量的前提之下，较常规边跨合龙方案，节省了桥梁边跨临时固结体系，降低了施工成本，提高了施工工效，能广泛应用于桥梁边跨合龙施工技术领域。
