Splicing method for converting space coordinates system of large-span spatial warping pipe truss

Abstract

The invention discloses a splicing method for converting the space coordinates system of a large-span spatial warping pipe truss. The method comprises the following steps of: 1, establishing a model of a large-span spatial warping pipe truss; 2, segmenting a hoisting section according to the characteristics of the spatial warping truss; 3, establishing an independent space coordinates system by taking any three points in four end points of the bottom chord of the segmented spatial warping truss as a plane; 4, determining the values of relative coordinate values X, Y and Z of each node in the independent space coordinates system; 5, setting a splicing tire of the hoisting section by using spatial position coordinate values in the independent space coordinates system; 6, inquiring the pipe diameter of a warping truss support point at a splicing section according to a construction plan determine the size of pipe bracket, determining the heights of a tire base and a branch pipe respectively, and manufacturing a splicing tire of the spatial warping pipe truss; and 7, completing splicing work. Due to the adoption of the splicing method, field splicing work of the large-span spatial warping pipe truss becomes more convenient, efficient and rapid, the construction period is shortened, and the construction cost is lowered greatly.

Description

Technical field: [0001] The invention belongs to a construction method of a steel structure building, in particular to an assembly method for transforming a space coordinate system of a large-span space twisted pipe truss. Background technique: [0002] With the development of social economy and construction technology, designers are using their imagination more and more in stadium buildings, making many conceptual things that could not be realized before become reality, such as the National Stadium (Bird's Nest), Beijing Phoenix International Media Center and other buildings. This type of building gives full play to the designer's rich imagination, organically combining plane, space, regular and irregular, forming a perfect visual effect of the building. But at the same time, such buildings also bring great challenges to the structural installation. [0003] At present, the on-site assembly of the space-distorted truss structure, considering the complexity and variability...
