Specific embodiment
The present invention is described further with reference to the accompanying drawings and examples.
In order to solve the above-mentioned technical problem used technical solution of the invention are as follows:
A kind of modeling method of the concrete T-shaped beam structural bridge based on skeleton line, passes through template parameter on bridge skeleton line
T beam structure template and bridge abutment moulding plate are established, the parameter changed in concrete T-shaped beam structure construction and condition and model are carried out
Association, then creates relevant framework information, is controlled by design table model parameter, finally by Automated assembly
Carry out rapid modeling.It specifically includes:
Step S1. first creates the model template of height parameter
Concrete T-shaped beam is made into a complete template by whole collapse, single bridge pier is made into template, and association can be in template
Control is such as left and right width, horizontal slope, and all multi-parameters including expansion joint type and length etc., these parameters can be changed to control mould
The outer dimension of type ensure that T girder construction can be changed with different types of curve.
Design parameter is as follows:
Concrete T-shaped beam: left and right width, horizontal slope！, expansion joint type, front end expansion joint, rear end expansion joint, beam the piece number, Liang Jian
Away from, side bar cantilever, Cast-in-Situ Segment edge spacing.Template input condition is center line and segmentation plane.
Bridge pier: left and right width, pier is high, and stake is long, horizontal slope, longitudinal slope, bent cap size, pier shaft size, bearing pad stone size, pier number.
Template input condition is coordinate.
Step S2. configures relevant design table, and the parameter for needing to change in the parameter and model in design table is associated.
The design table in assembling process is needed to configure according to detailed programs drawing,
Design table mainly include in assembling process different location reference different templates trim designs table and control template from
The size design table of body size.
Bridge pier size design table

Step S3. develops external program and generates skeleton line
Secondary development is carried out to CATIA three-dimensional software by C#, realization automatically generates bridge framework information.
By secondary development program code, across footpath distribution and coordinate arrangement are directly selected, it can be achieved that in software interface
Mass production full bridge structure axis net avoids and manually individually establishes the cumbersome of axis net in software, also more acurrate.Secondary development
Interface is as shown in Figure 5.Axis net is as shown in Figure 6.
Step S4. Automated assembly
By writing external knowledge engineering code, Automated assembly is realized, based on existing framework information and design table letter
Breath, control T beam forms adaptively assemble on skeleton line.
By the relevant information configured in bridge pier and T beam trim designs table, corresponding template is selected, successively chooses and has created
Axis net middle skeleton information is built as input condition, Automated assembly is realized by program batch.
Knowledge engineering part core code is as follows:
As shown in fig. 7, realizing the rapid modeling of concrete T-shaped beam structure, designer's work effect can be improved to a certain extent
Rate and work quality, model can possess higher parametrization degree, be suitable for a variety of project needs.
