Parametric modeling method of continuous girder bridge based on revit platform

Abstract

The invention relates to a Revit platform based continuous-girder-bridge parametric modeling method. The method includes: 1), leading in numerical values of coordinate points of box-girder sections ofa continuous girder bridge to generate a box-girder contour model; 2), adding datum lines, size markers and parameter constraints of the box-girder sections and establishing parametric three-dimensional box-girder component models; 3), according to instance data of a box girder, generating box-girder instance models of the entire bridge according to the parametric three-dimensional box-girder component models established in the step 2), and modifying names of the instance models of box-girder components according to actual needs; 4), establishing rebar models of the box-girder components; 5),establishing component models of bridge piers, bearing platforms and pile foundations. Automatic generation of statistic of work amount and drawings is achieved, and a good data platform foundation is provided for operation and maintenance of later bridge BIM (building information modeling); problems that two-dimensional drawings are repeated in data input, non-universal in data, dispersing in spatial relation, non-parametric, informative linkage forbidden in parameter design and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of bridge BIM (Building Information Modeling), in particular to a parametric modeling method for continuous beam bridges based on the Revit platform. Background technique [0002] With the rapid development of high-speed railways in my country, a large number of prestressed concrete continuous beams are used in the construction of high-speed railways, and continuous beams occupy a large proportion of railway bridge construction. Construction puts forward higher requirements. [0003] In the current related technology, the bridge drawings designed by designers are generally two-dimensional drawings, and the lengths and proportions of various lines in the drawings are manually set, which is prone to data errors; and it is difficult to find bridges in the plane display of two-dimensional drawings The data errors in the design make it difficult to provide accurate data support for bridge construction and bring i...
