Integrally-lifted special-shaped single-layer spherical reticulated shell prestress inhaul cable reinforcing method
The invention discloses an integrally-lifted special-shaped single-layer spherical reticulated shell prestressed steel strand inhaul cable reinforcing method which is characterized in that a middle supporting rod is arranged below a central circular ring of a special-shaped single-layer spherical reticulated shell structure, and a plurality of reinforcing steel strand connecting pieces are annularly arranged at the lower end of the middle supporting rod; and a plurality of tension connecting pieces are annularly arranged on the outer ring beam of the latticed shell structure, prestressed steel strand inhaul cables are arranged between the reinforcing steel strand connecting pieces and the tension connecting pieces in a pulling mode and are tensioned, the lifting part of the latticed shell is reinforced, and the chord support self-balancing latticed shell reinforcing structure is formed. The method of the scheme solves the problems that the integrally lifted special-shaped single-layer spherical reticulated shell is poor in rigidity, and the structure is easily damaged in the lifting process. A single-layer spherical reticulated shell structure with poor rigidity is converted into a chord support self-balancing reticulated shell structure with good rigidity through a prestressed steel strand inhaul cable reinforcing method, and the structural safety of overall lifting of the reticulated shell structure is ensured.
本发明公开了整体提升的异形单层球面网壳预应力钢绞线拉索加固方法，在异形单层球面网壳结构中心圆环处下方设置中撑杆，中撑杆的下端环向设置若干加固钢绞线连接件；网壳结构外环梁上环向设置若干个受拉连接件，在加固钢绞线连接件和受拉连接件之间拉设预应力钢绞线拉索并进行张拉，对提升部分网壳进行加固，使之形成弦支自平衡网壳加固结构。该方案的方法解决了整体提升的异型单层球面网壳刚性差、提升过程中容易造成结构破坏的困难。通过预应力钢绞线拉索加固方法，使刚性较差的单层球面网壳结构转换为刚性较好的弦支自平衡网壳结构，确保网壳结构整体提升的结构安全。
