Steel truss girder incremental launching construction method and device
The invention relates to a steel truss girder incremental launching construction method and device, and belongs to the technical field of bridge erection. The steel truss girder incremental launching construction method comprises the steps that S1, sliding blocks are arranged on a slide way beam to support joints of a steel truss girder, and a walking top is arranged at the front end of a groove of the slide way beam; s2, the walking top is used for driving the steel truss girder and the sliding blocks to move on the sliding way beam till the sliding block at the front end moves to the position over a groove of the sliding way beam; s3, the front-end sliding block is detached and moved to the position of the next joint of the steel truss girder; and S4, the step S2 and the step S3 are repeated till the steel truss girder is moved to the preset position. According to the construction method, when the sliding block is inversely used, the walking top does not need to be repeatedly used for lifting and lowering the steel truss girder, the groove position is ingeniously used for suspending the sliding block, the disassembly and assembly space is provided for the sliding block, meanwhile, the walking top does not need to be installed at the two ends of the steel truss girder, only the walking top needs to be arranged at the front end of the groove, the construction cost and the construction difficulty are reduced, and the construction efficiency is improved. The construction efficiency can be greatly improved, and the construction period is shortened.
本申请涉及一种钢桁梁顶推施工方法及装置，属于桥梁架设技术领域，该钢桁梁顶推施工方法包括：S1：在滑道梁上布设滑块支撑钢桁梁的节点处，并在滑道梁凹槽的前端布置步履顶；S2：利用所述步履顶带动钢桁梁和滑块在所述滑道梁上移动，直至使前端滑块移动至所述滑道梁凹槽正上方；S3：拆卸前端滑块移动至钢桁梁下一节点位置；S4：重复步骤S2和S3，直至移动钢桁梁至预设位置。采用本申请的施工方法倒用滑块时，不需要反复利用步履顶抬起和下放钢桁梁，巧妙利用了凹槽位置悬空滑块，提供给滑块拆装空间，同时不需要在钢桁梁的两端安装步履顶，只需要在凹槽前端布置步履顶，降低了施工成本和施工难度，可以大大提升施工效率，缩短施工周期。
