Temporary support for bridge superstructure construction
The invention relates to the technical field of bridge construction, in particular to a temporary support for bridge superstructure construction. Comprising a steel truss and a supporting mechanism supported at the lower end of the steel truss, the steel truss comprises a pair of bailey trusses and a pair of cross beams, the pair of bailey trusses are horizontally arranged side by side, the corresponding cross beam is horizontally arranged above each bailey truss, and each cross beam is fixedly connected with the corresponding bailey truss through an inclined strut; the supporting mechanism comprises a pair of first steel pipe pile mechanisms and one or more second steel pipe pile mechanisms. The prefabricated beams are evenly erected at the upper ends of the pair of cross beams through the square timber and are perpendicular to the pair of cross beams, the two ends of each prefabricated beam are fixed through the corresponding prefabricated beam inclined struts, and the first hydraulic jacks and the second hydraulic jacks are adjusted so that the prefabricated beams can be adjusted to the proper height. Therefore, the steel truss can be prevented from being damaged by torsion; the hydraulic jacks are self-locking hydraulic jacks and can bear for a long time, and long-term support is provided for construction of the cast-in-place straining beam.
本发明涉及桥梁施工的技术领域，特别涉及一种用于桥梁上部结构施工的临时支架。包括钢桁架和支撑在钢桁架下端的支撑机构，钢桁架包括一对贝雷架和一对横梁，一对贝雷架水平并排布置，每个贝雷架的上方水平布置对应横梁，且每根横梁和对应贝雷架之间通过斜撑固定连接；支撑机构包括一对第一钢管桩机构和一个以上的第二钢管桩机构；预制梁通过方木均匀搭设在一对横梁的上端，并且和一对横梁垂直布置，每块预制梁的两端分别通过预制梁斜撑固定，调节第一液压千斤顶和第二液压千斤顶，使得预制梁调整到合适的高度。因此本发明可避免钢桁架受扭力而损伤；液压千斤顶均采用自锁式液压千斤顶，可长久承载，为现浇系梁的施工提供长期支撑。
