Carrying device and method for silo wall slipform and silo top conical steel truss of squat silo

SU YUANHONG

The invention discloses a carrying device for a silo wall slipform and a silo top conical steel truss of a squat silo. The carrying device comprises a slipform hoisting system and a steel truss system, and is characterized in that the slipform system comprises a jack, a portal, a supporting steel pipe and a slipform carrying support; the steel truss system comprises steel truss girders, a core tube and double-lug-plate bases; the steel truss double-lug-plate bases are arranged at the ends of the steel truss girders, the steel truss girders bear the whole load of the construction of top plate concrete, and the double-lug-plate bases are connected with pull rods through steel bar plug pins. The carrying device has the advantages that a carrying joint is simple in design and structure, easy to machine, convenient to construct, safe and reliable in engineering quality, capable of being mounted and dismounted on the ground, and free of high-altitude suspension operation, safety is guaranteed, platform materials in the slipform are saved, and the problems of long post-lifting process time, high difficulty and high safety risk of the large steel truss are solved.

一种用于浅圆仓仓壁滑模仓顶圆锥形钢桁架的托带装置，包括滑模提升系统、钢桁架系统，其特征在于：所述滑模系统包括千斤顶、门架、支撑钢管、滑模托带支座，所述钢桁架系统包括钢桁架大梁、核心筒、双耳板底座，所述钢桁架双耳板底座设置在钢桁架大梁端部，钢桁架大梁承受顶板混凝土施工全部荷载，双耳钢板底座用钢棒插销与拉杆连接。本发明具有托带节点设计构造简单、加工容易，施工方便，工程质量安全可靠，安装拆除作业均在地面进行，无高空悬空作业、安全保证，节省了滑模内平台材料，解决了大型钢桁架后提升工艺时间长、难度大、安全风险高的难题的优点。
