Technical Field
The invention relates to the field of industrial three-dimensional forming, in particular to a three-dimensional rapid generation method of a steel bar.
Background
Steel reinforcement is a very important material in construction, which mainly plays a role in fixing concrete. Because of the various shapes of buildings, the shapes and the sizes of the reinforcing steel bars are different, such as: the reinforcing bar on one section arc wall, then its reinforcing bar just divides vertical straight reinforcing bar and horizontal curved reinforcing bar, and vertical reinforcing bar will insert the concrete of lower part, and horizontal reinforcing bar will transversely insert the concrete next to, and for the sake of firm, the mode of inserting also is different, and some are straight inserts, and some insert the back and bend down 90 degrees, some probably bend to one side, and some need take the crotch, and the complexity of reinforcing bar shape derives from the difference of building geometry on the one hand, still derives from the shape that the end anchor goes into in addition, the diverse of size. Most software uses parameter drivers to deal with size issues such as: a parameter srcd _ zhu is set to indicate that when the end is a column, the horizontal wall steel bar needs to be anchored into the column for a length, so that we can actually need to adjust their parameters, such as: the seismic rating, which is a parameter indicative of the number of seismic levels that the building can resist, is often also related to the anchor length.
However, many software enumerates common combination cases inside a program, but when a new case is encountered, the new case can be generated only by combining and expanding at a large cost or by making the new case approximate, the difficulty of the former method is multiplied, and the latter method is inaccurate in detail and cannot represent and describe the shape under the real condition.
