Reverse construction method concrete-filled steel tubular column reinforcing and supporting method
The invention discloses a reverse construction method concrete-filled steel tubular column reinforcing and supporting method. The reverse construction method concrete-filled steel tubular column reinforcing and supporting method comprises the following steps that a steel truss is manufactured according to measured deviation information of a defective concrete-filled steel tubular column; the steeltruss is hoisted to a mounting position, and supporting legs of the steel truss are fixed to the first-layer plate surface; the defective concrete-filled steel tubular column is fixed to a steel truss connecting column; after construction is carried out to the position of a bottom plate, permanent reinforcement measures are carried out on the defective concrete-filled steel tubular column again;and the steel truss is removed. When the bearing capacity of the poured steel tubular column is insufficient, a large truss system is used for reinforcing the bearing capacity of the concrete-filled steel tubular column, the problem that the bearing capacity of the concrete-filled steel tubular column is insufficient is solved, construction is carried out under the condition that reverse construction method construction is not affected, the subsequent construction procedure of the reverse construction method is guaranteed, and a guarantee is provided for the project progress; and the deflection generated when the concrete-filled steel tubular column is hoisted is small and is close to a statically indeterminate structure, and the structural stability, safety and reliability are guaranteedunder the condition that the concrete-filled steel tubular column deviates.
本发明公开了一种逆作法钢管混凝土柱补强支撑方法，包括步骤：根据测量出缺陷钢管混凝土柱的偏位信息，制作钢桁架；将钢桁架吊装至安装位置，并将钢桁架的支撑脚与首层板面进行固定；将缺陷钢管混凝土柱固定至钢桁架连接柱上；待施工至底板位置，重新对缺陷钢管混凝土柱进行永久性补强措施；移除钢桁架。当钢管柱浇筑完成后承载力不足时，利用大型桁架系统补强钢管混凝土柱的承载能力，解决了钢管混凝土柱的承载力不足问题，在不影响逆作法施工的情况下进行施工，保证了逆作法后续的施工工序，为工程进度提供了保证；吊重钢管混凝土柱时产生的挠度较小，接近超静定结构，在钢管混凝土柱出现偏差的情况下，保证了结构稳定性、安全性和可靠性。
