Construction method of continuous steel-concrete superposed beam
The invention discloses a construction method of a continuous steel-concrete superposed beam, which comprises the following steps: firstly, building piers, then building temporary brackets on the piers, and erecting a whole span of steel main beam on the temporary brackets, so that the whole steel main beam extends horizontally and transversely; the temporary supports located on the side piers are dismantled, so that the whole steel main beam is in a bent state; concrete is poured on the surface of the steel main beam in the bent state to form a concrete top plate structure; after the concrete top plate structure reaches the design strength, the temporary supports at all the middle supports are dismantled, the middle section of the continuous steel-concrete composite beam falls back to all the middle supports, and the construction operation of the continuous steel-concrete composite beam is completed; the method not only solves the problem of cracking of the concrete at the support in the continuous steel-concrete composite beam, but also solves the technical problem that in the prior art, a construction method for solving the problem of cracking of the concrete at the support in the continuous steel-concrete composite beam is tedious in operation and large in technical difficulty, so that the construction cost is high.
本发明公开了一种连续钢‑混叠合梁的施工方法，首先建造桥墩，然后在各个桥墩上搭建临时支架，并将整跨钢主梁架设在临时支架上，使钢主梁整体沿水平横向延伸；拆除位于边桥墩上的临时支架，使钢主梁整体处于弯曲状态；在处于弯曲状态的钢主梁表面浇筑混凝土，形成混凝土顶板结构；待混凝土顶板结构达到设计强度后，拆除各个中支座处的临时支架，使连续钢‑混叠合梁中段回落至各个中支座上，完成连续钢‑混叠合梁的施工作业；本发明不仅解决了连续钢‑混叠合梁中支座处混凝土的开裂问题，还解决了现有技术中用于解决连续钢‑混叠合梁中支座处混凝土的开裂问题的施工方法，操作繁琐、技术难度大，进而导致施工成本较高的技术问题。
