Problems solved by technology

More and more novel space steel structure types appear, such as large-scale bending-torsion space box steel structure or pipe truss structure, the appearance contour control lines of its components are mostly irregular space polylines, and these curves have no fixed curves equation, and the direction of the included angles of different arcs is constantly changing. The surface of the component forms an irregular bending surface, the appearance is extremely irregular, and the internal size is difficult to control. The traditional construction method can no longer meet the construction requirements. It is necessary to establish an accurate and safe temporary support tire frame system with the support of computer three-dimensional simulation modeling technology, and a more reasonable and higher-precision assembly method

Embodiment Construction

[0024] The invention provides a method for establishing a temporary support tire frame system for assembling large-scale steel structure building units. The method is: using computer three-dimensional modeling software to first establish a three-dimensional simulation of the large-scale steel structure that needs to be assembled. Model, and according to the simulation model to determine the assembly posture of the steel structure unit body and assembly segmentation; then according to the assembly posture optimization of the unit body to establish the assembly coordinate system, output the three-dimensional appearance control point of each characteristic appearance of the structure to be assembled under the assembly coordinate system Finally, according to the three-dimensional coordinate system and the assembly posture of the steel structure unit, a temporary support frame system that does not interfere with the unit members is designed.

[0025] The present invention adopts fol...

Abstract

The invention provides a method for establishing a temporary support moulding bed system for steel structure assembly. The method comprises the following steps: establishing a three-dimensional simulation model of unit bodies needing to be assembled of a large steel structure via three-dimensional computer modeling software at first, and determining unit body assembly postures and assembly sections of the steel structure according to the simulation model, then, optimizing and establishing an assembly coordinate system according to the assembly postures of the unit bodies, outputting three-dimensional coordinate of each feature appearance control point of the structure to be assembled in the assembly coordinate system, and finally, designing the temporary support moulding bed system generating no mutual interference with unit body members according to the three-dimensional coordinate system and the unit body assembly postures of the steel structure. The method provided by the invention can be used for solving the problems of high assembly difficulty and high control precision of large space steel structures and particularly steel structures with complex space modeling, such as box-shaped curved steel structures and the like, reducing the height of a construction working plane in assembly construction, guaranteeing the assembly precision, reducing the working risk, improving the construction efficiency and predictability and maximally reducing auxiliary construction materials.

Description

technical field [0001] The invention relates to the technical field of steel structure system construction for large stadium spaces, in particular to a [0002] The invention discloses a method for establishing a temporary support tire frame system for assembling structural building units. Background technique [0003] With the development of the national economy, it is necessary to build more and larger large spaces for sports, leisure, exhibitions, airports, hangars, etc. [0004] And the demand for super large space buildings is very strong. This kind of building form is generally a space steel structure, and the structure type can be divided into mesh [0005] frame (light steel), space truss (heavy steel), etc. These buildings usually have the characteristics of large span, unique shape, complex stress and regional symbolic significance after completion. After the appearance of this new building type of space steel structure, some new construction methods were deriv...
