Construction method of ultrahigh large-span silo top plate
The invention relates to the technical field of building construction, in particular to an ultrahigh large-span silo top plate construction method which comprises the following steps: leveling and reinforcing a steel pipe truss in a silo, starting to fix a sliding and lifting platform 24 hours after pouring of reinforced concrete on the topmost silo wall is completed, removing sliding and lifting templates and enclosures on the inner and outer silo walls, rooting at the silo wall of the silo top, and completing the construction of the ultrahigh large-span silo top plate. The whole steel pipe truss is supported by a steel pipe inclined strut at the position of each open frame; the construction method has the beneficial effects that the steel pipe lattice type rigid platform is adopted and stops sliding when sliding and rising to the elevation of the lower opening of the highest reinforced concrete beam of the silo, then the slip form lifting frame is temporarily fixed, the slip form rigid platform and the silo wall are connected through the silo wall embedded part, and supporting is added; load borne by the slip form rigid platform is transmitted to the cylinder wall.
本发明涉及建筑施工技术领域，具体为一种超高大跨度筒仓顶板施工方法，包括以下步骤：仓内钢管桁架调平、加固，最顶层仓壁钢筋混凝土浇筑完成二十四小时以后，开始固定滑升平台，拆除内外仓壁滑升模板及围圈，在仓顶仓壁处生根，在每榀开字架位置用钢管斜撑支撑整体钢管桁架；有益效果为：本发明提出的超高大跨度筒仓顶板施工方法，采用钢管格构式刚性平台，当滑升到筒仓仓最高钢筋混凝土梁下口标高后停滑，然后临时固定滑模提升架，通过仓壁预埋件将滑模刚性平台与仓壁连接并增加支撑，将滑模刚性平台承受的荷载传递到筒壁上。
