Method for simultaneous sliding and lifting of large-diameter prestressed inner silo and large-diameter prestressed outer silo
The invention relates to the field of steel structure construction, in particular to a method for simultaneous sliding and lifting of a large-diameter prestressed inner silo and a large-diameter prestressed outer silo. The method is characterized in that a hydraulic sliding and lifting formwork is adopted for construction operation, and the method comprises the following steps: step 1, erecting a sliding formwork device; step 2, erecting a central cylinder scaffold system; and step 3, carrying out sliding and lifting construction. According to the method for simultaneous sliding and lifting of the inner silo and the outer silo, simultaneous lifting of the inner silo and the outer silo is achieved, the method is economical, reasonable, simple, practical, safe and reliable, a formwork supporting system during later construction of a silo top cone is mainly and effectively achieved, and the construction speed is high; a central cylinder scaffold is additionally arranged, so that the deflection of a sliding formwork platform is effectively reduced, and the span of a single truss is effectively reduced; and after a silo top platform is closed, hoppers in the silos and the cone can work in a crossed mode, and the construction period is shortened.
本发明涉及钢结构施工领域，具体是一种大直径预应力内、外筒仓同时滑升的方法；其特征是：采用液压滑升模板施工作业，包括下述步骤：步骤1、搭设滑模装置；步骤2、搭设中心筒脚手架系统；步骤3、滑升施工。本发明所提出的内、外筒仓同时滑升方法，实现了筒内、筒外两筒同时提升，经济合理、简捷实用、安全、可靠，主要是有效的解决了后期施工仓顶锥体时的模板支撑体系，施工速度快；增加中心筒脚手架，有效的降低了滑模平台的挠度，有效的减少了单榀桁架的跨度；仓顶平台封闭后，仓内漏斗可以同时与锥体交叉作业，节约了工期。
