Description
Technical field
The present invention relates to power engineering construction technical field, and in particular to a kind of electric power pylon BIM based on Tekla platforms
Model building method.
Background technology
It can be seen that BIM technology can fully be melted in the promotion and application achievement of building trade by BIM technology in recent years
Input, the output information in each stages such as design-modeling-processing-construction-O＆M are closed, is improving engineering life cycle management
Significant effect in quality and efficiency.Therefore, BIM technology is used by increasing engineering construction industry.At present, BIM technology
It is applied successfully in some important power engineering projects, and achieves good economic benefit and social benefit.
Important component of the electric power pylon as work transmission line, establish electric power pylon BIM models to designing, plus
Work, construction and later stage operation management are significant.At present, electric power pylon completes the following rank of main needs experience from construction is designed into
Section：1st, designer is planned steel tower, modeled, calculated, and result of calculation is organized into commandant's figure；2nd, making drawing personnel is according to setting
The steel tower commandant that meter personnel provide schemes to draw two-dimentional construction drawing；3rd, processing factory according to two-dimentional construction drawing carry out three-dimensional lofting,
Project scene is sent to after examination assembling, batch production；4th, unit in charge of construction carries out the installation erection of steel tower.Many ask be present in above flow
Topic, it is incompatible with theory that is efficient, integrated, saving at this stage, it is mainly shown as following aspect：1st, the mould in design process
Type file and result of calculation file can not be designed, chart and process unit shares, and repetitive operation amount is big；2nd, pilot process is big
The artificial input and output of amount, increase the possibility of mistake generation under the influence of artificial subjective factor；3rd, designing unit needs and made
Map unit and process unit coordinate repeatedly, expend great effort；4th, presently used graphics software is all two-dimentional, drawing course
In can not check space collision, to have buried hidden danger of doing over again in post-production and work progress；5th, one can not be formed completely
3D hologram model, three-dimensional, which is transferred, needs other establishment officer to rebuild threedimensional model.
At present, there is the method for realizing steel tower BIM models in existing Design Transmission Line three-dimensional electronic platform, but they
Thinking be weight circuit and light railway tower, and propose method be highly dependent on itself company exploitation other more money softwares,
Cause this method that there is larger limitation；On the other hand, the method that iron tower model is created in power transmission sequence three dimensional design platform
It is to carry out analog representation by entity lines, the actual specification and section attribute of steel tower rod member can not be embodied, can not more be embodied
The parts such as the gusset plate and bolt that are connected between rod member, having no precision can say, still have larger area from real steel tower BIM models
Not.Also directly using the setting-out model of processing factory as steel tower BIM models, although the model can reach the precision of BIM models
It is required that but because processing factory's setting-out software data form is unsatisfactory for the international form such as IFC mostly, so can usually occur
Digitized with national grid and transfer the problem of management platform data are incompatible, meanwhile, these models also do not possess addition design, added
The ability of the additional informations such as work, construction, O＆M, it can not be reused, can not be referred to as by the participation unit in other stages of engineering
For steel tower BIM models.
The content of the invention
In view of this, the present invention provides a kind of electric power pylon BIM model building methods based on Tekla platforms, improves
The utilization rate of design phase achievement, caused wrong probability of happening when greatly reducing repeatedly artificial input, output；Model can
Directly it is designed unit, processing producer, unit in charge of construction and operation management unit to use, really realizes the mould of engineering life cycle management
Type and information management.
