Reticulated Cylindrical Steel Structure Reticulated Shell and Its Construction Method

Abstract

The invention provides a grid-shaped, cylindrical-surface and steel structured latticed shell and a construction method thereof. The grid-shaped, cylindrical-surface and steel structured latticed shell comprises eight elliptical frameworks which are mutually and slantly crossed and connected in a sleeving manner; the cross section of the grid-shaped, cylindrical-surface and steel structured latticed shell is circular and is divided into a front arc surface and a back arc surface; each elliptical framework is a closed structure constituted by a double-pipe truss and a single-pipe structure frame; the double-pipe trusses of the eight elliptical frameworks are positioned on the front arc surface; the single-pipe structure frames of the eight elliptical frameworks are positioned on the back arc surface. According to the invention, the elliptical frameworks are split into a plurality of arc-shaped components; the manner of segmental hoisting and piecewise installation is adopted to perform construction; the three-point hoisting manner is adopted to lift the arc-shaped components to a assigned position; adjusting steel wire ropes and adjusting chain blocks are utilized, so as to adjust the spatial position and rotation angle of the arc-shaped components; multiple safeguard measures are adopted, so as to realize accurate butting of the component connectors; the plane surface mounting position and height mounting position of the arc-shaped components are ensured; accurate installation of the rotation angle of the connector is ensured; the grid-shaped, cylindrical-surface and steel structured latticed shell and the construction method thereof can be extensively applied to the construction of large-scale space three-dimensional arc-shaped structures.

Description

technical field [0001] The invention relates to a building structure and a construction method, in particular to a special-shaped building structure and a construction method thereof. Background technique [0002] At present, the traditional building structure is relatively simple, and the common curved structure is a plane structure, mainly curved steel beams. However, with the development of the construction industry, various building structures have emerged. The traditional decorative skeleton cannot meet the current needs, and the installation method of the plane curved steel beam is directly hoisted in place and fixed on the completed structural column. This method The precision is easy to control, and the operation is relatively simple. However, if there is a more complex structure, such as a large-scale, large-scale three-dimensional arc-shaped component without a supportable structure, it is difficult for the general installation method to achieve such a high The in...
