Background
The BIM technology can be applied to various stages of engineering project investigation, design, construction, operation and maintenance and the like, realizes data sharing of all participants in the whole life cycle of a building on the basis of the same multi-dimensional building information model, and provides technical support for industrial chain communication, industrialized construction and prosperous building creation; the method supports the analysis and inspection of engineering environment, economy, quality, safety and other aspects, and provides a basis for the scheme optimization and scientific decision of the whole process of the project; and the system supports the cooperative work of each specialty and the virtual construction and fine management of projects, and creates conditions for quality improvement, efficiency enhancement, energy conservation and environmental protection of the construction industry.
The quantity and the type of the steel bars required by each construction stage are fixed, but the existing steel bar blanking matching method is still in a manual stage, systematic statistical calculation is not available, personal experience is relied on, the matching mode is disjointed with steel bar stock data, sometimes, no stock exists after the steel bars are matched and are taken out of a warehouse, temporary purchase is needed, meanwhile, steel bar straightening, steel bar cutting, steel bar bending and the like are not designed in advance, so that waste is serious, the steel bars matched with the steel bars taken out of the warehouse are not in accordance with the time sequence of steel bar warehousing, so that part of the steel bars are easy to rust for a long time, therefore, the steel bar blanking matching method not only can systematically analyze and calculate the steel bar matching mode, but also can timely butt the stock, and can generate a steel bar processing plan so as to solve.
