Large-span spherical roof truss pulling rod lifting construction method
The invention belongs to the technical field of general building structures, and provides a large-span spherical roof truss pulling rod lifting construction method. The method comprises the steps that hoisting points are arranged on a plurality of concrete columns of a high-speed rail station building; single-foot pulling rods are installed at a plurality of preset positions, and at most two single-foot pulling rods are arranged between every two adjacent concrete columns in the span direction of a spherical roof truss; and first pulley blocks arranged at hoisting points on two adjacent concrete columns in the length direction of the spherical roof truss, second pulley blocks matched with two single-foot pulling rods located on the ground in the length direction of the spherical roof truss, a guide pulley block and a plurality of winches are arranged, and a first net rack unit is hoisted to a floor platform to be assembled with a second net rack unit. The spherical roof truss assembled on the floor platform is hoisted to the designed elevation and fixed through the first pulley blocks on the multiple adjacent concrete columns, the second pulley blocks matched with the multiple single-foot pulling rods, the guide pulley block and the multiple winches.
本申请属于一般建筑物构造技术领域，提供了一种大跨度球形屋架拔杆提升施工方法。该方法包括：在高铁站房的多个混凝土柱设吊点；在多个预设位置安装独脚拔杆，球形屋架跨度方向上相邻两个混凝土柱之间至多有两个独脚拔杆；球形屋架长度方向上相邻两个混凝土柱上的吊点处的第一滑轮组以及与长度方向上的两个位于地面上的独脚拔杆配套的第二滑轮组、导向滑轮组和多台绞磨，将第一网架单元吊装至楼面平台与第二网架单元进行拼装；通过相邻的多个混凝土柱上的第一滑轮组，以及与多个独脚拔杆配套的第二滑轮组、导向滑轮组和多台绞磨，将在楼面平台拼装完成的球形屋架吊装至设计标高并固定。
