Embodiment

[0056] Example: see Figure 1 to Figure 8 , a super high-rise building reinforced layer steel structure truss pre-assembly method, comprising the following steps:

[0057] 1) Set up a pre-assembled platform on the ground in the factory: the pre-assembled platform includes several first H-shaped steels 1 and platform plates 2, the first H-shaped steels 1 are parallel to each other, and the upper flanges of all the first H-shaped steels 1 The plates are located on the same level, and the distance between two adjacent first H-shaped steels 1 is 0.5-1m; the platform plate 2 is laid on the upper flange plate of the first H-shaped steel 1 and connected with the upper The flange plates are fixedly connected, and the length direction of the platform plate 2 is perpendicular to the length direction of the first H-shaped steel 1; wherein, the platform plate 2 is formed by welding several steel plates. During the assembly process, the first H-shaped steel 1 is placed at a higher positio...

Abstract

The invention discloses a pre-assembling method for a steel structure truss of a reinforced layer of a super high-rise building. The method comprises following steps: 1), a pre-assembling platform iserected on the ground of a factory; 2), the truss of the reinforced layer is divided into three parts according to structural planes, the three parts include a core-tube inner ring truss part, a core-tube exterior projecting outrigger truss part and an outer ring truss part, and each part is divided into multiple components with a BIM technology; 3), the core-tube inner ring truss is pre-assembled; 4), the core-tube exterior projecting outrigger truss part is pre-assembled; 5), the outer ring truss part is pre-assembled. With adoption of the scheme integrating assembly and production, the pre-assembling is more convenient, precision and reliability are higher, and the assembling efficiency can be effectively improved; construction of the truss of the building reinforcing layer is more convenient, and the construction cost can be reduced.

Description

technical field [0001] The invention relates to the field of building construction supplies, in particular to a method for pre-assembling steel structure trusses for super high-rise buildings. Background technique [0002] With the vigorous development of steel structure buildings in my country, super high-rise buildings are gradually developing towards diversified functions and complex structures. More and more high-rise buildings need lateral force resistant structural systems such as outer frame + core tube + reinforced layer outrigger Meet the structural design requirements. Setting up reinforced floors in high-rise buildings can not only meet the requirements of building plane functions, but also meet the requirements of structural strength, stability, displacement and ductility. Among them, the outrigger structure connects the outer frame and the core tube, which enhances the integrity of the structure and gives full play to the overall effect of the space, thereby fur...
