Embodiment 1

[0028] Embodiment 1, a double-ball nested grid construction method, including making the inner ball mesh and the outer ball mesh in the factory, and transporting the inner ball mesh and the outer ball mesh to the construction site and assembling the tire frame into an installation sheet piece, transform the coordinate position of each spherical grid node on the outer circumference of the single piece on the assembly site, set up an assembled tire frame corresponding to the coordinate position of the spherical grid node on the assembly site, and use the land sample method to place the inner ball The mesh and the outer ball mesh are assembled into the installation single piece. Then each installation piece is assembled piece by piece by a temporary support frame to form a mutual nested inner tennis ball and an outer tennis ball. The installation piece is divided into an outer tennis ring single piece and an inner tennis ring single piece. Spherical lattice columns, inner spheric...

Embodiment 2

[0042] Embodiment 2, a double-ball nested grid construction method, rest platforms are set in the height direction of each lattice column, and the rest platforms are set every 5 meters to provide rest places for construction workers. A ladder is set inside each lattice column as a vertical passage, and a hoisting operation platform is set on the top of each lattice column.

[0043] Other methods of this embodiment are the same as in Embodiment 1.

Embodiment 3

[0044] Embodiment 3, a double-ball nested grid construction method, the construction of filling vacancies in steps S3, S4, and S5 described in Example 1 is carried out through the wooden springboard platform erected, and the construction of filling vacancies in steps S5 and S8 is carried out by The high-altitude hanging cage is carried out with the grid net climbing ladder.

[0045] The other methods of this embodiment are the same as in Embodiment 1 or 2.

Abstract

The invention discloses a double-ball nested net rack construction method, and solves the technical problem that in the prior art, a double-ball nested net rack is complex in construction and difficult in guaranteeing mounting accuracy. The double-ball nested net rack construction method disclosed by the invention comprises the steps of: setting measurement control points; measuring and paying offconstruction control wires for mounting single chips; assembling external net ball ring single chips and internal net ball ring single chips above a bed jig; arranging internal ball lattice columns and external ball lattice columns, and arranging common lattice columns; carrying out layered, partitioned and fragmented splicing on the external net ball ring single chips and the internal net ball ring single chips; and carrying out replenishment on the external net ball ring single chips and the internal net ball ring single chips in layers and between layers. According to the invention, a layered, partitioned and fragmented splicing mode is adopted, and symmetrical synchronous splicing and replenishing type splicing are combined, so that not only is double-ball nested net rack constructionrapidly, conveniently and reliably implemented, but also high mounting accuracy is ensured.

Description

technical field [0001] The invention relates to the technical field of spherical steel structure construction, in particular to a double-sphere nested grid construction method. Background technique [0002] With the development of cultural economy, gymnasiums, science and technology museums, and cultural centers have sprung up like mushrooms. Since the above buildings are all open public venues, they have the use requirements of large span and large space. In order to meet the above requirements, steel structural building. Steel structure buildings have the advantages of low energy consumption, less construction waste, and short construction periods, and are green buildings that meet sustainable development. Among the many forms of steel structure, the spherical grid structure is a practical and beautiful steel structure form, which can not only meet the structural performance requirements of large spans, but also has beautiful visual effects, especially suitable for the co...
