A method and system for automatic optimization of hyperbolic slabs based on BIM technology

Abstract

The invention discloses a BIM technology-based automatic double-parabolic slab optimization method and system. The method comprises the following steps of: reading a three-dimensional model of a double-parabolic slab; carrying out optimal fitting analysis on the three-dimensional model of the double-parabolic slab according to a precision parameter set by a user so as to obtain three-dimensional models of a plurality of single-parabolic slabs; carrying out error comparison between the three-dimensional model of the double-parabolic slab and the three-dimensional models of the single-parabolicslab; selecting the three-dimensional model, with the minimum error value, of the single-parabolic slab as a single-parabolic slab with an optimum scheme; and finally outputting the single-parabolic slab with the optimum scheme. According to the method and system, double-parabolic slabs can be automatically and rapidly fit and optimized into single-parabolic slabs, and the obtained single-parabolic slabs are high in precision, so that the requirements of double-parabolic slab machining process are greatly satisfied and the working efficiency and quality of optimization of engineers are improved; and the method and system can be widely applied in the field of building curtain wall design optimization.

Problems solved by technology

[0002] Hyperbolic panels, that is, hyperbolic aluminum, glass or stainless steel panels, etc., are more common in building curtain walls or metal roofing system engineering with curved surfaces in space, but hyperbolic panels have the characteristics of high processing difficulty, long processing cycle and high cost

Under the premise of meeting a certain accuracy range, the hyperbolic plate is fitted and optimized into a single curved plate, which can simplify the processing technology, reduce the production cycle and processing cost, but the traditional manual optimization is still used in the current optimization process, and traditional manual optimization exists Low efficiency, poor precision and other issues

Especially in large-scale construction projects with complex shapes and multiple systems, if manual optimization is used to optimize the fitting and optimization of hyperbolic slabs, the workload is not only large but also cumbersome, which requires a lot of energy and time for the participating designers. The construction period of large-scale construction projects is generally tight, and the project schedule and cost control have high requirements. If the construction period is delayed during the hyperbolic plate fitting optimization process, the time and economic cost of the project will undoubtedly be increased.
