Split type large-span steel bent cap structure and construction method thereof
The invention discloses a split type large-span steel cover beam structure and a construction method thereof.An original cover beam structure is vertically cut into two parts along the position of a middle web to form a first branch box beam and a second branch box beam, the first branch box beam is of a complete box beam structure and is provided with the middle web, and external stiffening ribs are arranged on the outer side of the middle web; the side, close to the middle, of the second sub-box girder is not provided with a web, the side, close to the middle, of the second sub-box girder is provided with a plurality of sets of components which are connected in a matched mode from top to bottom, finally, the components are fixedly connected into a whole, a large-span steel cover beam structure is formed, the split type structural design is adopted, and the first sub-box girder and the second sub-box girder can be machined and installed. The hoisting weight is greatly reduced, and the hoisting difficulty, the mounting difficulty and the construction cost are greatly reduced.
本发明公开了‑一种分体式大跨径钢盖梁结构及其施工方法，将原盖梁结构沿中腹板位置竖向切分为两部分，形成第一分箱梁和第二分箱梁，第一分箱梁是完整的箱梁结构，具有中腹板，并在中腹板外侧设置外加劲肋，而第二分箱梁则靠近中部的一侧未设置腹板，与第一分箱梁的中腹板一侧从上至下设置多组配合连接的构件，最终固定连接为一体，形成大跨径钢盖梁结构，分体式的结构设计，可分别对第一分箱梁和第二分箱梁进行加工及安装，大幅减轻吊装重量，大大减轻了吊装难度、安装难度及施工成本。
