Special-shaped steel tower closure section falsework lifting structure and construction method
The invention relates to a special-shaped steel tower closure section falsework lifting structure and a construction method, and belongs to the technical field of special-shaped steel tower construction. Comprising a hoisting construction part used for installing a temporary support, a vertical rotating part arranged on the hoisting construction part, a stabilizing part used for improving the stability between the hoisting construction part and the vertical rotating part, a falsework body arranged on the vertical rotating part and a lifting closure part arranged in the center of the vertical rotating part. A main tower is divided into an in-situ hoisting part, a vertical rotation part and a lifting closure part for construction, a floating crane is used for assembling a support in the main tower, a closure section is hoisted to the support, a falsework main body is erected after vertical rotation is conducted in place, lifting closure is conducted through the falsework main body, the lifting closure section is arranged on a steel tower, the weight of the vertical rotation part is reduced, the construction speed is increased, and the construction cost is reduced; the problems that in the prior art, an oval steel tower brings a new challenge to bridge construction, the construction speed is reduced, and the construction cost is increased are solved.
本发明涉及一种异形钢塔合龙段膺架提升结构及施工方法，属于异形钢塔施工技术领域，包括用于安装临时支护的吊装施工部、设置在吊装施工部上的竖转部、用于增加吊装施工部与竖转部之间稳定性的稳固部、设置在竖转部上的膺架主体和设置在竖转部中心的提升合龙部，将主塔分为原位吊装、竖转、提升合龙三部分进行施工，利用浮吊拼装主塔内支架，吊装合龙段至支架上，待竖转到位后搭设膺架主体，通过膺架主体提升合龙，钢塔设置提升合龙段减小了竖转部分重量，加快了施工速度，且减小施工成本，解决了现有技术中椭圆形钢塔给桥梁施工带来了新的挑战，会降低施工速度和加大施工成本的问题。
