Embodiment 1

[0043] Such as figure 1 As shown, the installation and construction process of the free-form surface single-layer reticulated shell structure on the roof of a super high-rise building:

[0044] (1) Measurement and setting out, ①Main control axis, set four projection reference points at the four corners of the floor surface, and ensure that each reference point can see through two adjacent reference points, ②Reticulated shell structure 1 solid line lead measurement ;

[0045] (2) Divide the reticulated shell structure 1 into blocks, segment the reticulated shell structure 1 according to the structural conditions, on-site installation conditions and transportation conditions, and divide the reticulated shell structure 1 into 62 small trusses and filling rods 5;

[0046] (3) Install the reticulated shell structure 1, ① install the bottom ring beam 2, ② set up a full hall scaffold, ③ install the top ring beam 3, ④ symmetrically install the main truss 4 on both sides of the east ...

Abstract

The invention discloses a method for installation construction of a roof free-form surface single-layer latticed shell structure of a super high-rise building. The roof free-form surface single-layer latticed shell structure comprises a building frame and a latticed shell structure arranged at the top of the building frame. The latticed shell structure comprises a bottom ring beam arranged at the top of the building frame, a top ring beam arranged at the top end of the latticed shell structure and a net-shaped truss arranged between the bottom ring beam and the top ring beam. The method is characterized in that a latticed shell structure installing process comprises the steps of performing measurement and setting out, partitioning the latticed shell structure, installing the latticed shell structure, performing painting make-up on welded nodes, performing fireproof coating construction, performing acceptance of engineering quality and dismantling an all-round scaffold. The method is good in construction quality and quick in speed and has safety in construction and good economic benefits and remarkable social benefits.

Description

technical field [0001] The invention relates to a method for installing a reticulated shell structure on the roof of a high-rise building, in particular to a method for installing a single-layer reticulated shell structure on the free-form surface of the roof of a super high-rise building. Background technique [0002] The reticulated shell structure is a kind of curved surface grid structure, which has the characteristics of simple structure of the rod structure and reasonable force of the thin shell structure. The reticulated shell structure can form a variety of curved surfaces on the building shape, giving designers full freedom of creation. It can not only express static beauty, but also express dynamic beauty through the cutting of plane and facade and the change of grid, support and rod. In recent years, the architectural design has been continuously developed. The reticulated shell structure has become an important structural form that combines technology and art by ...
