Study Of The Characteristic Of Firefighting Pipe Network Based On BIM

With the rapid development of the construction industry,building structure has been getting more and more complex,and the traditional CAD design as a result has been difficult to meet the requirements.BIM as an innovative tool and production method,whose propose has caused great changes in the construction industry.Although China's BIM application is still in the embryonic stage,the development of BIM and the realizing the transformation of construction industry has become an inevitable trend.As an important carrier of building information,BIM model contains almost all information related to architecture.Pipeline design as an indispensable part of architecture plays also an important role in the application of BIM technology.This paper would find the way at the Revit platform to check the fire pipe network of the BIM model for reducing the workload of the designer and bringing computer into playing a better role as auxiliary functions in the construction industry.In this paper,as a first step,the current research situation and development of BIM technology at home and abroad are investigated.Secondly,it introduces the popular modeling software on the market,analyzes the advantages and disadvantages of all kinds of modeling software,determines the tool and platform for the second development and describes briefly the tools needed for the second development and the Revit platform plug-Operation mechanism.Then,according to the analysis of fire pipe connection in the building,it extracts the connection information in the model to establish the tree topology and to determine the path of water flow according to its connection relation.At last,it extracts the basic information of the elements in the water flow path and accordingly carries out the hydraulic calculation.Through the comparison of the hydraulic pressure with artificial computational design pressure,it achieves a better way to check the hydraulic of the fire pipe network.
