Integral hoisting construction method for upper tower column framework
The invention discloses an integral hoisting construction method for an upper tower column framework. The method comprises the following steps. The method comprises the following steps: 1, designing an upper tower stiff skeleton; step 2, calculating the load of the stiff skeleton of the upper tower column; and step 3, integrally hoisting the stiff skeleton and the prestressed steel beam of the upper tower column. In order to guarantee accurate positioning of the high-strength steel wire bundles and guarantee safety of construction on the tower, the stiff framework and the high-strength steel wire bundles are assembled and integrally hoisted on the ground. The method also has the following beneficial effects. (1) under the condition that the whole-section framework and the segmented framework are hoisted at multiple hoisting points, the strength and the rigidity of the stiff framework meet the requirements; (2) a scissor inclined strut is installed according to a scheme drawing; (3) stiff skeleton nodes are connected through electric welding, the rod pieces are welded through connecting plates when necessary, connecting weld joints are in a three-face welding mode, and the welding height is not smaller than 5 mm; (4) strictly controlling the machining precision of the framework and the welding quality of each node; and (5) in the implementation process, all the lifting points are stressed in a balanced mode, and stable lifting is achieved.
本发明公开了一种上塔柱骨架整体吊装施工方法；具有如下步骤；步骤1，上塔柱劲性骨架设计；步骤2，上塔柱劲性骨架荷载计算；步骤3，上塔柱劲性骨架及预应力钢束整体吊装。本发明为保证高强钢丝束精确定位，为确保塔上施工安全，劲性骨架和高强钢丝束在地面组拼整体吊装。还具有如下方面的有益效果；(1)整节骨架和分节骨架在多吊点吊装情况下，劲性骨架强度、刚度满足要求；(2)按方案图纸安装好剪刀斜撑；(3)劲性骨架节点通过电焊连接，必要时杆件与杆件间通过连接板焊接，连接焊缝为三面焊，焊接高度不得小于5mm；(4)严格控制骨架加工精度、各节点焊缝质量；(5)实施过程中，各吊点要均衡受力，平稳起吊。
