Light combined box girder structure and construction method thereof
The invention discloses a light combined box girder structure which comprises a steel box girder and a UHPC top plate laid on the top of the steel box girder, the steel box girder comprises a closed steel shell with a through inner cavity and a plurality of partition plates arranged in the closed steel shell, the UHPC top plate is fixedly connected to the top face of the closed steel shell, and a shearing force connecting piece embedded in the UHPC top plate is arranged on the closed steel shell. The invention further discloses a construction method thereof. By means of the steel box girder formed by the closed steel shell and the multiple partition plates welded in the closed steel shell, the geometric size of a component can be remarkably reduced, the self weight of the structure is reduced, connection is extremely firm, and the structural strength is high; the steel box girder can serve as a supporting formwork during pouring of the UHPC top plate, the defects of conventional pouring can be avoided, the bearing capacity and the structural anti-fatigue performance are high, the connecting strength of the UHPC top plate and the steel box girder can be remarkably improved through the shearing force connecting pieces, the overall stress capacity is high, the manufacturing process of the combined box girder structure is simplified, and the production cost is reduced.
本发明公开了一种轻型组合箱梁结构，包括钢箱梁和铺设于钢箱梁顶部的UHPC顶板，钢箱梁包括具有贯通内腔的闭合钢壳和多个设于闭合钢壳中的隔板，UHPC顶板固定连接于闭合钢壳的顶面上，闭合钢壳上设有埋设在UHPC顶板中的剪力连接件。本发明还公开了其施工方法。本发明通过闭合钢壳和多个焊接于闭合钢壳中的隔板所形成的钢箱梁，能显著减小构件的几何尺寸，减轻了结构自重，且连接极其牢固且结构强度高；钢箱梁能充当UHPC顶板浇筑时的支撑模板，也能避免常规浇筑缺陷，承载能力和结构抗疲劳性能强，通过剪力连接件，能显著提高UHPC顶板与钢箱梁的连接强度，整体受力能力强，并简化了组合箱梁结构的制作流程，降低了生产成本。
