Description

Technical Field

[0001] The invention relates to the technical field of large-area field concrete construction, and specifically to a large-area field concrete construction method based on BIM. Background Art

[0002] Building Information Modeling (BIM) is a three-dimensional building model based on various relevant information data of construction projects, which simulates the real information of the building through digital information simulation. It has eight characteristics: information completeness, information relevance, information consistency, visualization, coordination, simulation, optimization and mappability. The construction unit, design unit, construction unit, supervision unit and other project participants are on the same platform to share the same building information model. It is conducive to project visualization and refined construction;

[0003] The prior art CN107448022A discloses a BIM-based method for constructing a large-area, ultra-long floor in a food cold storage. The floor to be constructed is divided into several casting areas and numbered. The model is modeled using the revit2015 design software, and then the model is exported and imported into naviswork2015. Time nodes are assigned to unit engineering quantities, and a 4Dbim construction simulation animation is produced. The floor is constructed by partition casting. The odd-numbered areas are cast first, and the mold is removed when the concrete strength grade reaches more than 50% of the design strength. Then, the even-numbered areas are cast. After all the casting is completed, an integral floor structure is formed.
