Abstract

The invention relates to the technical field of building construction, and discloses an intelligent beam stirrup generation method based on dynamo. The method mainly comprises the steps that positioning points of stirrups are obtained according to the section of one side of a beam; a stirrup positioning curve is generated, the offset distance of the stirrup positioning curve is generated accordingto the length of the associated beam, the stirrup positioning curve of the corresponding limb number is intelligently generated according to the stirrup limb number, the interval and the stirrup diameter input by a user, the stirrup curve is rapidly generated through the offset distance, and finally a stirrup model is generated. The method is operated on a visual programming plugin Dynamo of mainstream BIM software Revit, accurate positioning of the beam stirrups is achieved through a computer programming statement, the corresponding stirrups are accurately generated under the condition of different limb numbers of the beam stirrups, and the beam stirrups are rapidly generated on a plurality of beams in batches at the same time. The method can well improve the modeling speed of the beam stirrup, and has the advantages of improving the field machining precision of the sorghum stirrup, improving the construction efficiency and the like.

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) Method for rapid modeling of construction of stirrups. 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, and it is precisely because of the modeling process that a series of BIM functions can be completed. Therefore, t...
