Abstract

The invention discloses a steel bar three-dimensional modeling and automatic calculation method based on a BIM technology. The invention belongs to the field of building information models, the methodcomprises the following steps: firstly, researching a creation method of a novel parameterized component family different from an existing steel bar family on a Revit Stretch platform; secondly, realizing automatic generation of a steel bar detail table based on a parameterized component family, and finally finishing interactive modification with a Revit graph in an Excel table to realize visualmodification of component parameters. According to the invention, modification of geometric information and steel bar information of the component driven by parameters can be realized through creationof a parameterized component family; meanwhile, the nesting problem which cannot be completed by an existing steel bar family can be solved, the steel bar quantity list is automatically generated through parameter design, real-time control over the steel bar quantity is facilitated, steel bar discharging and bin dividing are conducted in a targeted mode, and waste of steel bar tailings is reduced.

Description

technical field [0001] The invention belongs to the field of building information models, and in particular relates to a three-dimensional modeling and automatic calculation method for steel bars based on BIM technology. Background technique [0002] The arrival of BIM (Building Information Modeling) is a great revolution in the construction engineering industry. BIM, that is, Building Information Modeling, is the combination of computer digital information technology and graphics technology, the informatization of construction engineering, and a new concept of engineering construction. Different from the traditional CAD two-dimensional graphic design method, it is a digital parametric modeling technology, which can not only realize the simulation of engineering information, but also realize the collaboration of various disciplines, with visualization, coordination, simulation, optimization and Five characteristics of mapability. It jumps construction engineering informati...

Problems solved by technology

The current building structure is generally more complicated, and the size and specifications of the steel bars used in different structural parts are also quite different. In the flat drawing design, a complex structure needs 5~6 plan drawings to show all the structural details. With the popularization and promotion of BIM technology, the application of BIM is becoming more and more extensive. Through the parametric modeling of BIM, the model can be updated synchronously, and the modification and adjustment are linked. However, the 3D reinforcement modeling has not yet been well integrated into the In the category of BIM design, although there is a structural modeling part in BIM, there are many limitations in the application process, such as the inability to modify parameters, the inability to nest families, and the drawing process is relatively complicated
