Construction system for counter-pulling, arching, balancing and side turning of steel pipe arch ribs
The invention discloses a construction system for counter-pulling, arching, balancing and side turning of steel pipe arch ribs. The lattice frame is linearly connected with a pair of skewbacks, the short supports are arranged along the linear curve of the arch ribs and are connected with the pair of skewbacks, the tower columns are arranged in the lattice frame and are higher than the short supports, the counter-pulling devices are arranged between the short supports and the arch ribs on one side, and the counter-pulling devices are arranged between the arch ribs on the two sides through the tower columns. The opposite-pulling device comprises a pair of guide pulleys arranged on the top of the tower column, tensioning equipment arranged on the top of the tower column and opposite-pulling steel strands connected with the arch ribs on the two sides from the tensioning equipment respectively. The tower column higher than the short support is arranged, the arch camber angle is larger than 0 degree, the traction force of arch camber lateral rotation is conveniently and finely controlled, in addition, the tensioning device of the opposite-pulling steel strand is arranged at the top of the tower column, namely, the tensioning device is arranged in the middle of the opposite-pulling device, the traction force of arch ribs on the two sides can be balanced and controlled, and the control method of the lateral rotation traction force is simplified.
本申请一种钢管拱肋对拉起拱平衡侧转的施工系统，其包括直线连接一对拱座的格子架、沿拱肋线型曲线排列的连接一对拱座的矮支架、设置在所述格子架中的高于矮支架的若干个塔柱、设置在所述矮支架与单侧拱肋之间的反拉装置以及经过所述塔柱设置在两侧拱肋之间的对拉装置；所述对拉装置包括设置在所述塔柱顶部的一对导向滑轮、设置在所述塔柱顶部的张拉设备，以及从所述张拉设备分别连接两侧拱肋的对拉钢绞线。本申请设置高于矮支架的塔柱，使起拱角度大于0°，便于精细化控制起拱侧转的牵引力，另外将对拉钢绞线的张拉设备设置在塔柱顶部，即在对拉装置中居中设置，能够平衡控制两侧拱肋的牵引力，简化了侧转牵引力的控制方法。
