Hoisting method for bidirectional bending and twisting dome support
The invention discloses a hoisting method for a bidirectional bending-twisting dome support, and relates to the technical field of building construction method.The hoisting method for the bidirectional bending-twisting dome support comprises the following steps that firstly, a basement foundation pit is constructed; 2, constructing a steel knot truss; and thirdly, a roof structure is installed, and the second step further comprises the steps that after main body steel structures on the two sides of the truss are installed, a stable frame system is formed, meanwhile, the truss temporary support is installed in place and is inspected to be qualified, and truss rod pieces are hoisted through an on-site tower crane. The truss is segmented by considering factors such as the weight, the distribution position, the tower crane performance and the transportation condition of the truss, in-situ high-altitude splicing is adopted in the truss installation scheme, the component segmentation principle is adopted, component transportation deformation can be prevented, the field welding operation space is guaranteed, manufacturing and installation are convenient, intersection and overlapping of welding seams are avoided as much as possible, and the construction efficiency is improved. And the welding stress concentration and the field welding amount are reduced.
本发明公开了一种双向弯扭穹顶支架吊装方法，涉及建筑施工方法技术领域，该双向弯扭穹顶支架吊装方法包括以下步骤：步骤一：地下室基坑的施工；步骤二：钢结架桁架施工；步骤三：屋盖结构的安装，所述步骤二还包括：待桁架两侧主体钢结构安装完成，形成稳定的框架体系，同时桁架临时支撑安装到位并经检验合格后，利用现场塔吊开始桁架杆件吊装。本发明通过考虑桁架重量、分布位置、塔吊性能及运输条件等因素对桁架进行分段，桁架安装方案采用原位高空拼装，采用构件分段原则，可以防止构件运输变形，且保证现场焊接操作空间，方便制作、安装，尽量避免焊缝交叉、重叠，减少焊接应力集中及现场焊接量。
