Annular double-layer truss and manufacture method thereof

Abstract

The invention discloses an annular double-layer truss and a manufacture method thereof. The annular double-layer truss comprises two huge columns, wherein an outer frame truss, an inner frame truss, a box-shaped rod connected between the outer frame truss and the inner frame truss and at least two corner columns are arranged between the two huge columns. The outer frame truss is connected with the two huge columns and the corner columns respectively. Two ends of the inner frame truss are connected with the two huge columns, and the outer frame truss and the inner frame truss are connected through the box-shaped rod to form a whole. The truss is large in volume and size and is manufactured through connecting nodes in a segmented mode. A structural system is optimized to the most extent while the annular truss ensures structural bearing force, saving of raw materials is facilitated, the investment is saved, especially structural weight is lightened, and aseismatic ductility is improved. By means of the manufacture method, the problem of industrialized production can be solved, the manufacture progress is accelerated greatly, and a construction period can be shortened. In addition, the welding difficulty and the working amount are reduced by adopting reasonable segmented design, the construction is facilitated, the construction measure cost is reduced, and the construction period is shortened.

Description

technical field [0001] The invention belongs to a steel structure, in particular to a complex annular double-layer truss composed of K-shaped joints, rice-shaped joints and box-shaped bars and a manufacturing method thereof. Background technique [0002] Guangzhou Zhujiang New City East Tower is located in the center of Zhujiang New City CBD. The project faces Zhujiang Avenue in the west and Huacheng Avenue in the north. It forms twin towers with the West Tower on the opposite side, which are located on both sides of the central axis of the new city. The south faces the newly built building across the river Guangzhou New TV Tower, north of Tianhe Sports Center. [0003] The East Tower includes three parts: the tower, the podium and the basement. The tower is 518 meters high and has 112 floors above the ground. After completion, it will surpass the Guangzhou West Tower (440.75 meters) and become the tallest building in South China. At that time, the "three highs" of Zhujiang ...

AI Technical Summary

Problems solved by technology

[0004] A total of 6 ring trusses are arranged along the height of the tower in this project. There are two types of spanning the first floor and spanning the second floor. The volume and size of the ring truss are very large. If the traditional assembly process is adopted, it is cumbersome and the positioning accuracy is difficult to assemble on site. Guarantee, so if the traditional assembly process is far from meeting the requirements of the engineering cycle, and the workpiece needs to be hoisted up and down during the operation, this will increase the safety risk
