Large-span prestressed steel beam stable supporting structure and construction method
The invention relates to the technical field of steel beam supporting structures, and discloses a large-span prestressed steel beam stable supporting structure and a construction method.The large-span prestressed steel beam stable supporting structure comprises a steel beam, supports are fixedly connected to the bottoms of the two ends of the steel beam, inhaul cable structures are arranged on the two sides of the steel beam, and steel beam stiffening ribs are evenly arranged on the two sides of the steel beam; the two supporting structures are used in a matched mode and symmetrically installed on the two sides of the steel beam; and a plurality of groups of secondary beams are arranged and are used for fixedly connecting the two groups of steel beams. In order to solve the problem that the pre-tension force cannot reach a structural design value due to the fact that the pre-stress steel beam applied to a large-span space is prone to lateral bending when a stable system is not formed during ground tensioning, a lateral support is additionally arranged in a steel beam pre-stress area, the lateral rigidity of the steel beam is increased, and it is guaranteed that the pre-tension force can reach the design value.
本发明涉及钢梁支撑结构技术领域，公开了一种大跨度预应力钢梁稳定支撑结构及施工方法，包括钢梁，所述钢梁两端底部均固定连接有支座，所述钢梁两侧均设置有拉索结构，钢梁两侧均匀布置钢梁加劲肋；还包括支撑结构，所述支撑结构为两组配合使用，且对称安装于钢梁两侧；次梁，所述次梁为多组，且用于对两组钢梁进行固定连接。本发明为了解决应用于大跨度空间的预应力钢梁，在地面张拉时未形成稳定体系时，钢梁容易出现侧向弯曲，导致预拉力达不到结构设计值，并通过在钢梁预应力区增加侧向支撑，增加钢梁的侧向刚度，保证预拉力能够达到设计值。
