Small-radius box girder bridge structure and construction method thereof
The invention discloses a small-radius box girder bridge structure and a construction method thereof, relates to the technical field of bridges, and mainly aims to reduce the manufacturing difficulty and cost of a template and solve the problem of high lofting precision requirement during construction of a prefabricated box girder. According to the main technical scheme, the structure comprises a middle beam, at least two rows of connecting steel plate sets which are sequentially arranged from top to bottom are embedded in webs on the two sides of the middle beam, and each row of connecting steel plate set comprises a plurality of connecting steel plates arranged at intervals; at least two rows of connecting steel plate groups which are sequentially arranged from top to bottom are pre-buried on a web plate on one side, adjacent to the middle beam, of the side beam; the cross beams are located between every two adjacent middle beams and between the middle beams and the edge beams and connected between every two corresponding connecting steel plates, and every two vertically adjacent cross beams are located in the same section; the supporting beams comprise at least two inclined supporting beams, the at least two inclined supporting beams are obliquely connected between the two cross beams located in the same section, and a triangle is defined by the at least two inclined supporting beams and the cross beams.
本发明公开了一种小半径箱梁桥结构及其施工方法，涉及桥梁技术领域，主要目的是降低模板的制作难度和成本，以及解决预制箱梁施工时放样精度要求高的问题。本发明的主要技术方案为：该结构包括中梁，中梁的两侧腹板上均预埋有上下依次布置的至少两排连接钢板组，每排连接钢板组包括多个间隔设置的连接钢板；边梁，边梁上与中梁相邻一侧的腹板上预埋有上下依次布置的至少两排连接钢板组；多个横梁，位于相邻两个中梁之间以及中梁和边梁之间，并分别连接于相对应的两个连接钢板之间，且上下相邻的两个横梁位于同一断面内；多个支撑梁，包括至少两个斜撑梁，至少两个斜撑梁倾斜地连接于位于同一断面内的两个横梁之间，并与横梁围成三角形。
