Construction method for integrally towing conical truss support by sliding formwork of large silo
The invention discloses a construction method for integrally towing a conical truss support by a sliding formwork of a large silo. The construction method comprises the following construction steps of assembling a sliding formwork device and a conical truss, towing the conical truss by the sliding formwork to integrally slide and lift, fixing the conical truss after sliding and lifting are completed, constructing a conical shell top, and removing the conical truss, wherein the sliding formwork device is connected with an inner platform and an outer platform, support steel pipes in the sliding formwork device are lengthened with a welding method, welding lining pipes are additionally arranged at joints of the support steel pipes, the number of the joints of the support steel pipes at the same height is smaller than 25% of the total number, the outer platform comprises a rectangular truss cantilever platform which is formed in a way that an upper chord, a vertical web member, an inclined web member and a lower chord are welded, and channel steel is welded to the upper chord and the lower chord respectively and is in bolted connection with the sliding formwork device through bolts. According to the construction method, the process difficulty and the safety risk of post lifting of the large steel truss are overcome, the use amount of turnover materials is greatly reduced, the site in the silo is not occupied, and the ground construction in the silo is not restricted; and the construction site is saved, and on-site safe and civilized construction management is facilitated.
本发明公开了一种大型筒仓滑模整体拖带锥形桁架支撑施工方法，包括以下施工步骤：滑模装置及锥形桁架组装、滑模拖带锥形桁架整体滑升、滑升完成后固定锥形桁架、锥壳顶施工、锥形桁架拆除，滑模装置连接有内平台和外平台，滑模装置中的支撑钢管采用焊接方法接长，支撑钢管的接头处增加焊衬管，同一高度上支撑钢管的接头数小于总量的25%；外平台包括矩形桁架悬挑平台采用上弦杆、竖腹杆、斜腹杆和下弦杆，上弦杆和下弦杆分别焊接有槽钢，槽钢通过螺栓与滑模装置螺栓连接。本发明克服了大型钢桁架后提升的工艺难度和安全风险，周转材料用量大大减少，不占用仓内场地，不制约仓内地面施工；节约施工场地，有利于现场安全、文明施工管理。
