Segmented alternate jacking method for stacking column core through steel slide ways and high-precision and high-strength concrete cushion blocks
The invention discloses a technical method for alternate stress and segmented jacking of a column core formed by stacking a steel slide way and a high-precision and high-strength concrete cushion block. A steel slide way underpinning system is formed by the steel slide way, the hanging lower bracket, the upper bracket or the tray beam, the hydraulic jack and the like. When the steel slide way is stressed, the load of an upper structure is sequentially transmitted to the hydraulic jack, the suspension lower bracket and the steel slide way through the upper bracket or the tray beam and finally transmitted to a lower structure or a foundation. When the column core is stressed, the load of an upper structure is transmitted to a lower structure or a foundation through the column core formed by stacking the high-precision and high-strength concrete cushion blocks. Jacking by a certain height is carried out alternately until the column core is stressed, a steel plate is used for sealing the outside of the steel slide way to form a steel pipe column, fine aggregate concrete is poured to form a combined steel pipe concrete column, the process of one-section jacking and repeated segmented jacking is completed, and jacking storey adding of the building is achieved. Through the technology, building storey adding can be efficiently, safely and economically achieved, the problem that the space of an old building is insufficient is solved, and the requirement for high-quality development is met.
本发明公开了一种利用钢滑道与高精度高强度砼垫块叠成的柱芯交替受力、分段顶升的技术方法。通过钢滑道、悬挂下牛腿、上牛腿或托盘梁、液压千斤顶等组成钢滑道托换体系。钢滑道受力时，上部结构荷载通过上牛腿或托盘梁依次传递给液压千斤顶、悬挂下牛腿、钢滑道，最后传递至下部结构或基础；柱芯受力时，上部结构荷载通过高精度高强度砼垫块叠成的柱芯传递给下部结构或基础。顶升一定高度、交替至柱芯受力时，用钢板将钢滑道外封成钢管柱，浇注细石混凝土形成组合钢管混凝土柱，完成一段的顶升，重复分段顶升的过程，实现建筑物的顶升增层。通过该技术可高效、安全、经济的实现建筑物增层，解决老旧建筑空间不足的问题，符合高质量发展的要求。
