Full framing prestress tensioning and prepressing structure and construction method
The invention discloses a full framing prestress tensioning and prepressing structure and a construction method. The prestress tensioning and prepressing structure comprises a bottom tensioning foundation fixed to a foundation and a top tensioning mechanism arranged at the top of a full framing. The top tensioning mechanism is connected with the bottom tensioning foundation through a plurality of detachable prestressed steel bars and tightly presses the full framing on the foundation. The top tensioning mechanism comprises an upper top beam and a plurality of supporting parts which are arranged at intervals and supported between the upper top beam and the top of the full framing, and the prestressed steel bars are detachably connected with the upper top beam. Stable pressure is downwards applied to the full framing from the top of the full framing, so that a continuous and stable reinforcing effect is provided for the full framing; the device is simple in structure, convenient to construct, disassemble and assemble and capable of being repeatedly used, meanwhile, the on-site construction quality of the full framing can be effectively improved, and the overall construction measure cost and the material cost are effectively reduced.
本发明公开了满堂支架预应力张拉预压结构及施工方法，预应力张拉预压结构包括固定在地基上的底部张拉基础以及设置在满堂支架顶部的顶部张拉机构，顶部张拉机构通过多个可拆卸的预应力钢筋与底部张拉基础连接并将满堂支架压紧在地基上；顶部张拉机构包括上顶梁和多个间隔排布设置并支撑在上顶梁与满堂支架顶部之间的支撑部件，预应力钢筋与上顶梁可拆卸连接。本发明从满堂支架的顶部向下对满堂支架施加稳定的压力，从而为满堂支架提供持续稳定的加固效果；本发明结构简单、便于施工拆装并可重复使用，同时能够有效提高满堂支架的现场施工质量、有效降低整体施工措施费及材料费用。
