Mounting method of special-shaped steel structure and mounting method of steel grid structure
The invention provides a mounting method of a special-shaped steel structure and a mounting method of a steel grid structure. The mounting method of the special-shaped steel structure comprises the following steps that the special-shaped steel structure is sequentially divided into a vertical section, a transition section and a horizontal section from high to low according to the structural characteristics of the special-shaped steel structure; an operation platform is erected on the external wall of a tower building, and the operation platform is used to fix scattered pieces in the vertical section and connect the scattered pieces integrally; a plurality of first temporary supports are arranged on the roof of a skirt building at the periphery of the tower building, and the transition section is hoisted to a set mounting position; and a plurality of branch columns are mounted on the roof of the skirt building, and the branch columns are used as the centers to assemble all the scatteredpieces of the horizontal section and connect the scattered pieces into a whole. According to the mounting method of the special-shaped steel structure and the mounting method of the steel grid structure, by using a top-down reverse construction method, the vertical section, the transition section and the horizontal section are sequentially mounted, the tower building is used as the center, mounting is carried out from inside to outside, the site utilization rate can be increased greatly, and meanwhile the control over the structural stability is more reasonable.
本发明提供了一种异形钢结构的安装方法及钢网架结构的安装方法，异形钢结构的安装方法包括：根据异形钢结构的结构特点将所述异形钢结构由高到低依次划分为竖向段、过渡段及水平段；在塔楼的外立面上搭设操作平台，利用所述操作平台将所述竖向段的散件固定并连接成一个整体；在所述塔楼周边的裙房楼顶设置若干第一临时支撑，将所述过渡段吊运至设定安装位置；在所述裙房楼顶上安装若干树杈柱，以所述树杈柱为中心拼装所述水平段的各个散件并连接成一个整体。本申请通过采用自上而下的逆向施工方法施工，即依次安装竖向段、过渡段和水平段，且以塔楼为中心，从内到外进行安装，能够很大程度提高场地利用率，同时在结构稳定性的控制上也更加合理。
