Embodiment Construction

[0030] The present invention will be further described below in conjunction with specific embodiments.

[0031] See figure 1 , The construction method of a multi-variable curved surface steel concrete tube structure of the present invention includes the following steps:

[0032] First, build a building information model through BIM application software;

[0033] Then, use AutoCAD application software to process the building information model to obtain the spatial coordinate data of each positioning template 1 of the cylindrical structure;

[0034] The data processing steps include:

[0035] Obtain the positioning curve of the horizontal section of each elevation of the building information model through AutoCAD;

[0036] Radial ray to the positioning curve of the current elevation at every 3 degrees from the central axis of the cylindrical structure at each elevation;

[0037] Pick up all the intersections of the positioning curve and the ray at each elevation, and use the space coordinat...

Abstract

The invention discloses a construction method of a variable curved-surface steel-concrete tubular structure, which includes the steps: establishing a building information model; subjecting the building information model to data processing to obtain space coordinate data of positioning forms of the tubular structure; performing construction layout according to the space coordinate data and fabricating the positioning forms; installing and reinforcing the positioning forms; and performing casting. By the construction method, construction of the variable curved-surface steel-concrete tubular structure is achieved, the solid sensory artistic effect of the variable curved-surface steel-concrete tubular structure is guaranteed, cost is low, and facade streamline is highly continuous in variation.

Description

Technical field [0001] The invention relates to a construction method of a building structure, in particular to a construction method of a multi-variable curved surface steel concrete tube structure. Background technique [0002] The multi-variable curved surface tube structure appears in the building. Due to the complex structure and strange appearance of the multi-variable curved surface tube structure, the tube body is like an inverted irregular cone from the bottom up, and the shape is not planned to develop or deform from the bottom up. , The construction process is quite complicated, especially the forming of section steel and steel bars, template positioning, blanking, assembly, selection and installation of inner and outer template materials, design and implementation of template brackets, erection and removal of internal molds in a small space, The choice of concrete cutting height and vibrating method need to abandon conventional thinking. If the general and convention...
