Parametric modeling production method for precast beam

Abstract

The invention discloses a parametric modeling production method for a precast beam. According to the method, self-defined parameters are used to perform assignment on structural side boundaries, steel bars and keyways of the precast framework beam, the side boundaries of the precast framework beam can be subjected to size control just through parameters in a family-type window, meanwhile, the length of the steel bars in a structural layer can change along with changes of the size of the side boundaries, and the quantity of stirrups can be increased or decreased along with size changes of the beam. A parameter model is utilized to make drawings, the quantity of horizontal drawings, the quantity of vertical drawings, the quantity of profile drawings and information needing to be expressed can be adjusted according to needs, and due to the fact that views are derived from the same model, it can be guaranteed that information of all the views are in complete correspondence. By use of the method to establish the three-dimensional model of the precast beam and make the drawings, efficiency is greatly improved, and meanwhile the accuracy of the made drawings is guaranteed.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a parametric modeling production method of prefabricated beams. Background technique [0002] The advantages of concrete prefabricated components are well known. It is not only a symbol of building industrialization, but also makes a lot of contributions to cost reduction, energy saving and emission reduction. In recent years, prefabricated concrete components have been widely used in the construction industry, and the demand has gradually increased. However, in terms of detailed design of precast concrete components, most design units still use traditional 2D CAD software for detailed design. In the prior art, CAD is used to draw the detailed design drawings of prefabricated beams. The horizontal, vertical, and cross-sections of components need to be drawn step by step with commands such as straight lines, and there are too many repeated operations. At the same time, th...

Problems solved by technology

If an error is found or the plan changes during the drawing process, it will inevitably take a lot of time to modify the drawing

The traditional CAD drawing method, manual drawing of horizontal, vertical and cross-sections, and positioning of steel bars, is prone to errors, which makes the workload of reviewing and modifying drawings in the later stage very heavy.
