Research On The In-depth Design Of EPSC Lattice Integrated Wall Based On BIM

In several years,China advocate the Green Building Policy rapidly,which is energy conservation and environment protection.Cement polystyrene framework(EPSC)lattice integrated wall as a new building wall has become a leader in the furture development within the construction industry.A series of advantages such as energy saving,fire insulation,and fast construction progress.As a new type of building wall,which is just the beginning in the design.Due to the complexity of its structure,which is difficult to solve the problem only rely on the two-dimensional design.Because lacking of design depth not only affects the production and installation of emerging walls,but also limits the promotion and application.In order to solve this problem,BIM technology is combined with new building walls to design,produce and apply in-depth design research.The main research contents are as following:(1)Through the deepening design of EPSC walls components,the split parameteric design of EPSC wall building is put forward.The Revit family is used to parametrically design its conventional components,and a standardized library of regular component families is established.Parametric design of T-shaped,L-shaped,cross-shaped and other heterosexual components is carried out in the form of nested families through the conventional component family library.(2)Based on the secondary development of Dynamo rebar,the parametric design of EPSC wall rebar is proposed.Because the parameterized design of spiral stirrups is too complicated,which cannot be carried out by conventional means.Through the secondary development of rebar,the parametric design of spiral stirrups,reinforced lattice columns,EPSC wall openings,and the reinforcement of the lintel were realized.(3)The subroutine software package of Dynamo and Revit coordinate conversion was independently developed in the Dynamo visual programming through the Python language.It solved the change of the coordinate position caused by the combination of the Dynamo entity and the Revit entity,which result in implant subroutine modules into Revit and apply them to actual engineering projects in a short time.(4)Based on the combination of RevitAPI technology and WPF technology,the EPSC wall component parameterized management platform was independently developed on the VisualStudio platform through the C # language.It was achieved R & D design and realized the parameterization of EPSC wall components management and call.Also,the independent development of the application of the parameterized management platform has realized the material statistics of EPSC wall components and the method of importing the engineering quantity list into Excel,which improves the efficiency.(5)Taking actual engineering as an example,the EPSC wall parameterized management platform is combined with the Dynamo rebar secondary development to complete the rapid modeling and reinforcement and real-time material extraction.It further verified the feasibility of BIM technology in new wall building and proved its application value in engineering.
