Integrally prefabricated pi-shaped composite beam, combined bridge structure and construction method
The invention relates to an integrally prefabricated pi-shaped composite beam, a combined bridge structure and a construction method. When an existing composite beam is constructed, a gap exists between a prefabricated slab and a steel main beam, and the durability of a bridge is reduced. The invention provides a pi-shaped composite beam which comprises a plurality of steel beam sections connected in the bridge direction, each steel beam section comprises two steel girders arranged in parallel at intervals in the transverse bridge direction, and the ends of the steel girders of the adjacent steel beam sections in the bridge direction are connected into a whole through web assemblies arranged in the transverse bridge direction. Solid web type connecting plates are at least arranged between the end portions of the inner side faces of the two steel main beams located on the steel beam sections at the two ends and between the inner side faces of the two steel main beams located on the middle steel beam section, and a K-shaped truss is further arranged between the inner side faces of the two steel main beams of each steel beam section. The pi-shaped composite beam is integrally prefabricated and integrally spliced with a composite beam with the same width as a bridge in a real bridge, so that the mounting speed and the construction quality of the on-site bridge are improved.
本发明涉及一种整体预制π型组合梁、组合式桥梁结构及施工方法。现有的组合梁在施工时预制板与钢主梁之间存在间隙，降低了桥梁的耐久性。本发明提供一种π型组合梁，包括若干节顺桥向连接的钢梁节段，所述每节钢梁节段包括两片横桥向并列间隔设置的钢主梁，所述顺桥向相邻钢梁节段的钢主梁端部通过横桥向设置的腹板组件相连接为一体，至少在所述位于两端钢梁节段的两片钢主梁内侧面端部之间和位于中间钢梁节段的两片钢主梁内侧面之间设置有实腹式连接板，在所述每节钢梁节段的两片钢主梁内侧面之间还设置有K型桁架。本发明的π型组合梁采用整体预制与实桥中一幅桥梁宽度相同的组合梁整体拼装，提高了现场桥梁的安装速度和施工质量。
