The present application provides a component processing method of a BIM assembly type project, and fig. 2 is a flowchart of a component processing method based on a BIM assembly type project according to an embodiment of the present application, and as shown in fig. 2, the flowchart includes the following steps:

s201, building a BIM model of the prefabricated part;

the prefabricated components are steel, wood or concrete components and the like which are prefabricated according to design specifications;

cast-in-place components are components that need to be processed on site during construction, for example, structural components of cast-in-place concrete;

the post-cast component is a post-cast component in the construction process, in order to prevent harmful cracks generated due to shrinkage or other subsequent work requirements, a part of structure needs to be reserved and poured after the work is finished, and the part of the reserved structure is called as the post-cast component in building modeling.

Further, the prefabricated units may be various common units such as prefabricated walls, prefabricated beams, prefabricated panels, and the like. It should be noted that the process of establishing the BIM model of the prefabricated part is a conventional technical means in the art, and the specific implementation steps are the same as those in the conventional manner, and therefore are not described in detail in this embodiment.

S202, obtaining and identifying a drawing to be processed to obtain modeling data corresponding to the drawing to be processed, wherein the modeling data comprises data and a layer;

the drawing to be processed can be a CAD (computer-aided design) construction drawing, and the drawing to be processed comprises other cast-in-place components and post-cast components except the prefabricated components. Furthermore, the process of identifying the model data to be processed and obtaining the model data to be processed is realized in the application environment of the building modeling software. Through the modeling software, information in the CAD drawing can be extracted and identified, and data and layers for generating two-dimensional and three-dimensional building models are further obtained.

And S203, determining the modeling data to be cast-in-place modeling data or post-cast modeling data according to the two-dimensional and three-dimensional relationship between the modeling data and the BIM of the prefabricated part.

The post-cast modeling data and the cast-in-place modeling data can be modeling data of a beam or a plate:

it should be noted that, in the fabricated engineering, the post-cast beam is a relative name of the cast-in-place beam, and is located above the precast beam or in a place in linear contact with the precast beam, and the post-cast beam and the precast beam jointly form a composite beam.

Specifically, in the fabricated engineering: the precast beam is a horizontal component, and the precast wall is a vertical component;

examples are as follows: in a certain fabricated project, the width of a precast beam is assumed to be 300cm, the height of the precast beam is assumed to be 550cm, and the construction requirement is that the beam height is 700cm. In the process of identification modeling, namely deducting data within the range of the height 550 of the precast beam (precast data), the assembly engineering standard refers to the data of 550-700cm as post-cast data.

In the embodiment of the application, when the cast-in-place part and the post-cast part are distinguished, the data to be processed is distinguished to be cast-in-place component data or post-cast component data by judging the height relationship between the modeling data to be processed and the arranged prefabricated components based on the logical relationship.

And S204, distributing component type information to the cast-in-place modeling data or the post-cast modeling data, modeling based on the distributed component type information, and generating a building information model.

The process of assigning component type information, i.e., the process of adding an identifier to the modeling data, is described above. Furthermore, when the system is used for modeling, corresponding modeling is carried out according to the identification, in the generated building information model, the post-cast modeling data correspondingly generate a post-cast component, and the cast-in-place modeling data correspondingly generate a cast-in-place component.

Through the above steps S201 to S204, compared to the related art, the building modeling method that distinguishes the cast-in-place member and the post-cast member cannot be identified. In the application, the cast-in-place modeling data and the post-casting modeling data are automatically and accurately determined. When the model is generated, modeling is carried out according to the marked data, so that the cast-in-place component and the post-cast component can be accurately identified in the generated model. Compared with a method needing manual secondary editing in the prior art, the method can automatically match component types through one modal frame, and further improves modeling efficiency.

In some embodiments, the prefabricated parts include: the prefabricated wall, the prefabricated beam and the prefabricated plate; correspondingly, the drawing to be processed may also include: liang Shuju, plate data, and plate bar data.

In some embodiments, determining cast-in-place modeling data and post-cast modeling data from the to-be-processed modeling data according to two-dimensional and three-dimensional relationships between the to-be-processed information and the BIM model of the prefabricated part specifically includes the following steps:

judging whether the height of the BIM model of the prefabricated part is overlapped with the height of modeling data or not; if the modeling data to be processed (model components to be generated) are overlapped, namely, the prefabricated parts exist in the height range, and correspondingly, according to the assembly type engineering standard, the non-overlapped part of the modeling data is determined to be post-pouring modeling data compared with the configured prefabricated parts, and the data is used for generating the post-pouring components.

Further, if the BIM model of the prefabricated part and the modeling data are not overlapped in height, that is, no prefabricated part is generated in the height range of the modeling data to be processed (model component to be generated), the part of modeling data is considered as cast-in-place modeling data and is used for generating the cast-in-place part.

FIG. 3 is a schematic diagram comparing a post-cast component and a cast-in-place component according to embodiments of the present application, as shown in FIG. 3:

the transverse structural part of the beam structure shown on the left side of fig. 3 has a lower half part which is a precast beam and an upper half part which is a post-cast beam; the transverse structural part of the beam structure shown on the right side of fig. 3 is entirely composed of cast-in-place beams.

In some of these embodiments, where the identification object is a beam and/or a slab, the method further comprises:

respectively distributing component type information to cast-in-place modeling data and post-pouring modeling data, wherein the cast-in-place modeling data are distributed into cast-in-place beams and/or cast-in-place plates, and the post-pouring modeling data are distributed into post-pouring beams and/or post-pouring plates;

and modeling based on the component type information to generate a building information model.

Specifically, in the case of identifying and modeling a beam, the specific implementation process includes:

firstly, establishing a BIM model of a prefabricated part, clicking and identifying a Liang Motai frame in a modeling function menu, extracting information of a beam in a CAD drawing according to the content indication of a modal frame, and performing quantity identification setting;

further, extracting modeling data (data and layers) in a CAD drawing, and judging whether the beam to be generated is overlapped with the prefabricated part which is already arranged in height or not by identifying a conversion condition which is arranged in a Liang Motai frame, so as to distinguish whether the data corresponds to a cast-in-place beam or a post-cast beam; and if the data to be processed is overlapped, judging that the modeling data to be processed is the data of the post-cast beam, and if not, judging that the data to be processed is the data of the cast-in-place beam.

Further, when the identification object is a slab, the specific operation implementation flow is similar to the flow of the beam, and a person skilled in the art can distinguish and generate the technical effect of the cast-in-place slab and the post-cast slab according to the above disclosed content and by combining specific variables without creative work, and therefore, details of the method are not repeated in this embodiment.

In some embodiments, the identification of the cast-in-place steel bars and the post-cast steel bars is associated with the identification of the plates, namely, in the process of generating the building information model by modeling, the steel bars in the cast-in-place plates are allocated as the cast-in-place plate bars, and the steel bars in the post-cast plates are allocated as the post-cast plate bars;

in some embodiments, in order to meet the national fabricated project consumption quota requirement, the prefabricated members, the cast-in-place members and the post-cast members can be subjected to independent quantity pricing summary according to the type information in the generated building information model, and a visual form is generated.

It should be noted that the steps illustrated in the above-described flow diagrams or in the flow diagrams of the figures may be performed in a computer system, such as a set of computer-executable instructions, and that, although a logical order is illustrated in the flow diagrams, in some cases, the steps illustrated or described may be performed in an order different than here.
