The invention relates to an assembly type building supporting system fast circulation method based on a BIM and belongs to the technical field of building construction. The assembly type building supporting system fast circulation method includes the following steps that S1, a building three-dimensional model is built through the BIM according to a designed drawing; S2, components of the buildingthree-dimensional model are determined; S3, multiple building units are divided, and each building unit is correspondingly provided with a component stacking position; S4, the number and kinds of components needed by each building unit are determined, the components of each building unit are marked, and corresponding tags are manufactured; S5, the tags are attached to the components needed by eachbuilding unit; S6, the components are transported and enter the area, and the components are stacked to the corresponding component stacking positions according to tag information; and S7, during construction, each building unit uses the components at the corresponding component stacking position. When each building unit is constructed, the components at the component stacking position corresponding to the building unit are directly lifted for construction work, the time needed by component lifting is effectively shortened, and the building construction efficiency is improved.

The invention discloses a BIM-based prefabricated building quick process design method. The method comprises the seven steps of quickly splitting a prefabricated building process; parametrically automatically generating prefabricated member process nodes such as rabbets, grooves and the like of members; parametrically automatically generating reserved embedded parts of the members; parametricallyautomatically generating steel bars of the members; automatically generating a prefabricated member process design graph and a BOM; and automatically generating prefabricated member family files. Based on a Revit platform, the Revit platform is subjected to secondary development. The system, while having basic advantages of visual design, convenient modification and the like of BIM software, greatly shortens modeling time and graph generation time in a prefabricated building process design process, can at least shorten existing prefabricated building process design time by 50%, and provides convenience for subsequent process design and adjustment.

The invention relates to the technical field of engineering quantity splitting and statistics, and discloses an engineering quantity splitting and statistical system. The method of the system comprises the steps that a scanner scans a paper design drawing to obtain an electronic version of the paper design drawing; image recognition system software running on a terminal for partial item decomposition operation reads the operation content from the drawing; a partial item decomposition service platform establishes an automatic partial item decomposition model, performs automatic partial item decomposition, and outputs data of engineering quantity splitting and statistical results; the partial item decomposition service platform outputs the data to an engineering management business system server in the engineering management information system; and an engineering management terminal calls engineering quantity splitting and statistical data from the engineering management business systemserver. The drawing can be automatically recognized, on one hand, errors generated by manual drawing reading can be reduced, on the other hand, efficiency can be improved, only manual rechecking is needed, standardization of achievements can be improved through standardized operation, and later-period work can be conveniently carried out.

The invention provides an automatic prefabricated part splitting method based on BIM and a computing device. The method comprises the steps that an overall BIM of a building project is designed, splitting parameters are built, and splitting rules for the number, the classification, the output information content and the project amount of a prefabricated part are made according to the preset splitting parameters; the overall BIM is classified according to the splitting parameters, and a building type is determined, so that mistakes are prevented from being made in the subsequent splitting process; the overall BIM is split into refined models step by step through two-time splitting, and in the subsequent part verification process, only part of models need to be verified, and the overall model does not need to be verified, so that the work efficiency is improved; the overall BIM is decomposed into a set of various parts and split into the minimum units meeting the production manufacturingand transporting requirements, and the part shapes are subjected to restoration verification, so that splitting errors are avoided; a production drawing of the part shapes is directly output, and theaim of one-key splitting design of the prefabricated part is achieved with the combination of the splitting requirements of the prefabricated part. Therefore, the accuracy and the efficiency for designing the drawing of the prefabricated part based on the BIM are improved.
