Preassembly method for building construction based on BIM technology

Abstract

The invention provides a preassembly method for building construction based on a BIM technology. The preassembly method comprises the steps that S100, according to parameters of a building construction component drawing, a dynamic parameter model library is constructed and a three-dimensional virtual model of building components is generated; S200, the three-dimensional virtual model of the building construction components is verified and compared with a physical model; S300, according to verification and comparison results, the parameters of the building construction components are adjusted;S400, the three-dimensional virtual model of the building construction components is built to generate a building preassembly three-dimensional effect graph; S500, coordinates of the central positionof a connection point in a preassembly drawing are acquired in a three-dimensional coordinate system, and errors are analyzed. The preassembly method for building construction based on the BIM technology has the advantages that the BIM technology is utilized to replace manual assembly of the building construction components, not only is the error between the building construction component drawingand a product analyzed, but also the positions of connection joints of physical assembly of the building construction components can be corrected, and the smoothness of physical later assembly of thebuilding construction components is ensured.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a BIM technology-based pre-assembly method for building construction. Background technique [0002] Building Information Modeling (BIM) is a complete information model that can integrate engineering information, processes and resources in different stages of the project's life cycle into one model, which can be easily used by all parties involved in the project. Through the three-dimensional digital technology to simulate the real information of the building, it provides a coordinated and internally consistent information model for engineering design and construction, so that the model can achieve the integration of design and construction, and all disciplines can work together, thereby reducing the cost of engineering production. Ensure that projects are completed on time and with high quality. [0003] BIM is to use the created BIM model to improve design quality, reduce d...

Problems solved by technology

[0004] However, the existing pre-assembly method of building construction based on BIM technology has the following defects: in the prior art, the pre-assembly method of building construction based on BIM technology mostly uses the three-dimensional physical model of the building construction components to simulate the pre-assembly through software. The quality of the building construction components cannot be controlled before the simulation, and the building construction components with large structural parameter errors cannot be eliminated, resulting in the subsequent pre-assembly of the building construction failing to achieve the expected effect, and there are certain defects
