Abstract

The invention relates to the technical field of building construction. The invention particularly relates to a BIM method for automatically generating longitudinal bars and side structural steel barson the lower portion of a beam. The method mainly comprises the steps of establishing a beam structure model through a mainstream BIM software platform Revit in a BIM technology implementation process; intelligently calculating various parameters of the lower longitudinal bars and the side structural steel bars of the beam through visual programming, and finally generating multiple steps such as constructing rebars of lower longitudinal ribs and side ribs of beams, wherein the steps meet the design picture set in the national building standard entitled " drawing rules for an overall representation method of concrete structure construction maps and details of construction". Information, a core factor of BIM technology, is integrated from concrete engineering to steel engineering connection.Therefore, a most fundamental and important step in the application process of BIM technology. The invention quickly builds the steel bar model in BIM model to form structural information of steel bars and guide construction. The invention can be widely applied in the steel bar modeling process of the floor frame beam, greatly improving the modeling speed of the steel bar and enhancing the application effect of the BIM technology.

Description

technical field [0001] The present invention relates to a technical field of building construction, in particular to a BIM-based design for floor frame beams in the national building standard design atlas "Concrete Structure Construction Drawing Plane Integral Representation Method Drawing Rules and Structural Details" (16G101-1) A method for rapid modeling and construction of lower longitudinal reinforcement and side structural reinforcement. Background technique [0002] Building Information Modeling (Building Information Modeling) is based on the relevant information data of the construction project as the basis of the model to establish the building model, and simulate the real information of the building through digital information simulation. It has five characteristics of visualization, coordination, simulation, optimization and plotting. [0003] BIM modeling technology is the basis of BIM technology application, it is precisely because of the modeling process that ...
