Suspended dome with adjustable prestress in service period and prestress adjusting method
A suspended dome with adjustable prestressing force in the service period comprises a reticulated shell, a tensioning integral structure and a support, rod pieces in the reticulated shell are connected through welding ball joints, and the tensioning integral structure comprises annular inhaul cables, radial inhaul cables, supporting rods, supporting rod upper joints, supporting rod lower joints and annular cable connecting joints; the annular inhaul cable and the radial inhaul cable are each composed of a double-lug anchorage device, a pin shaft, an adjusting sleeve, a two-way adjusting screw and an inhaul cable body. The supporting rod is composed of a top end universal hinge, a circular steel pipe with a built-in thread and a two-way adjusting screw rod. The supporting rod upper joint is connected with the latticed shell rod piece, the supporting rod and the radial inhaul cable. The supporting rod lower joint is connected with a supporting rod, an annular inhaul cable and a radial inhaul cable. The annular cable connecting nodes are connected with different cable sections of the same circle of annular inhaul cables; matched tensioning tools are arranged at the lower joints of the annular inhaul cables, the radial inhaul cables and the supporting rods respectively. The prestress in the service period can be adjusted, multiple times of prestress compensation can be carried out, construction operation is simple, the tensioning tool can be designed and manufactured in a standardized mode, and efficiency is guaranteed.
一种服役期预应力可调的弦支穹顶，包括：网壳、张拉整体结构和支座，网壳中杆件通过焊接球节点相连，张拉整体结构包括环向拉索、径向拉索、撑杆、撑杆上节点、撑杆下节点和环索连接节点；环向拉索和径向拉索均由双耳锚具、销轴、调节套筒、双向调节螺杆和拉索索体组成；撑杆由顶端万向铰、内置螺纹的圆钢管和双向调节螺杆组成；撑杆上节点连接网壳杆件、撑杆和径向拉索；撑杆下节点连接撑杆、环向拉索和径向拉索；环索连接节点连接同一圈环向拉索的不同索段；所述环向拉索、径向拉索、撑杆下节点处分别设置配套的张拉工装。本发明不仅实现服役期内预应力可调，并能进行多次预应力补偿，而且施工操作简单，张拉工装可标准化设计、制造，保证效率。
