Description

[0048] The present application provides a component processing method for a BIM prefabricated project, Figure 2 which is a flowchart of a component processing method for a BIM prefabricated project according to an embodiment of the present application, as Figure 2 shown. The process includes the following steps:

[0049] S201, establish a BIM model of prefabricated components;

[0050] Among them, the prefabricated components are components such as steel, wood or concrete prefabricated according to design specifications;

[0051] The cast-in-place components are components that need to be processed on-site during the construction process. For example, the structural components of cast-in-place concrete;

[0052] The post-cast components are parts of the structure that need to be reserved during the construction process to prevent harmful cracks caused by shrinkage or for other subsequent work requirements, and then poured after the work is completed. This part of the reserved structure is called a post-cast component in building modeling.

[0053] Further, the above-mentioned prefabricated components can be various common components, such as prefabricated walls, prefabricated beams and prefabricated slabs, etc. It should be noted that the process of establishing the BIM model of prefabricated components is a conventional technical means in the art, and the specific implementation steps are the same as the conventional methods, so they will not be elaborated in this embodiment.

[0054] S202, obtain the drawing to be processed and perform recognition to obtain the modeling data corresponding to the drawing to be processed, where the modeling data includes data and layers;

[0055] Among them, the to-be-processed drawings can be CAD building drawings, which include other cast-in-place components and post-cast components in addition to the above-mentioned precast components. Further, the process of identifying them to obtain the to-be-processed modeling data is realized in the application environment of building modeling software. Through this modeling software, the information in the CAD drawings can be extracted and identified, and then the data and layers for generating two-dimensional and three-dimensional building models are obtained. In this embodiment, these data and layers are defined as modeling data.

[0056] S203. According to the two-dimensional and three-dimensional relationships between the modeling data and the BIM model of the precast components, determine whether the modeling data is cast-in-place modeling data or post-cast modeling data.

[0057] Among them, the post-cast modeling data and the cast-in-place modeling data can be the modeling data of beams or slabs:

[0058] It should be noted that in the prefabricated project, the post-cast beam is the relative name of the cast-in-place beam. It exists above the precast beam or in the place where it is in linear contact with the precast beam. The post-cast beam and the precast beam together form a composite beam.

[0059] Specifically, in the prefabricated project: the precast beam is a horizontal component, and the precast wall is a vertical component;

[0060] For example: In a certain prefabricated project, assume that the width of the precast beam is 300 cm and the height is 550 cm, and the construction requirement for the beam height is 700 cm. During the identification and modeling process, the data within the range of the precast beam height of 550 (precast data) is deducted. The prefabricated project standard refers to the data in the range of 550 - 700 cm as post-cast data.

[0061] In the embodiment of the present application, when distinguishing the cast-in-place part and the post-cast part, based on the above logical relationship, by judging the height relationship between the to-be-processed modeling data and the precast components that have been arranged, the to-be-processed data can be distinguished as cast-in-place component data or post-cast component data.

[0062] S204. For the cast-in-place modeling data or the post-cast modeling data, assign component type information, and perform modeling based on the assigned component type information to generate a building information model.

[0063] Among them, the process of assigning the component type information is the process of adding identifiers to the modeling data. Further, when the system performs modeling, it performs corresponding modeling according to the above identifiers. In the generated building information model, the above-mentioned post-cast modeling data will correspondingly generate post-cast components, and the cast-in-place modeling data will correspondingly generate cast-in-place components.

[0064] Through the above steps S201 to S204, compared with the building modeling methods in the related art that cannot identify and distinguish cast-in-place components and post-cast components, in this application, the cast-in-place modeling data and the post-cast modeling data are accurately determined automatically. When generating the model, modeling is performed according to the data after the above marking, so that the cast-in-place components and the post-cast components can be accurately identified in the generated model. Compared with the traditional method that requires manual secondary editing, in this application, a modal box can be used to automatically match the component types, thereby improving the modeling efficiency.

[0065] In some of these embodiments, the above precast components include: precast walls, precast beams, and precast slabs; correspondingly, the drawings to be processed may also include: beam data, slab data, and slab reinforcement data.

[0066] In some of these embodiments, according to the two-dimensional and three-dimensional relationships between the information to be processed and the BIM model of the precast components, the cast-in-place modeling data and the post-cast modeling data are determined from the modeling data to be processed, which specifically includes the following steps:

[0067] Judge whether there is an overlap in height between the height of the BIM model of the precast component and the height of the modeling data; if there is an overlap, it is considered that there is a precast component within the height range of the modeling data to be processed (the model component to be generated). Correspondingly, according to the above prefabricated engineering standards, it is determined that in this part of the modeling data, the non-overlapping part compared with the configured precast components is the post-cast modeling data, and this part of the data will be used to generate the post-cast components.

[0068] Furthermore, if there is no overlap in height between the BIM model of the precast component and the modeling data, that is, there is no generated precast component within the height range of the modeling data to be processed (the model component to be generated), then it is considered that this part of the modeling data is the cast-in-place modeling data and is used to generate the cast-in-place components.

[0069] Figure 3 is a comparison schematic diagram of post-cast components and cast-in-place components according to an embodiment of the present application, as Figure 3 shown:

[0070] In Figure 3 the left-side transverse structural part of the beam structure shown, the lower half is a precast beam, and the upper half is a post-cast beam; in Figure 3 the right-side transverse structural part of the beam structure shown, it is all composed of cast-in-place beams.

[0071] In some of these embodiments, when the object to be identified is a beam and / or a slab, the method further includes:

[0072] Component type information is respectively assigned to the cast-in-place modeling data and the post-cast modeling data, wherein the cast-in-place modeling data is assigned as cast-in-place beams and / or cast-in-place slabs, and the post-cast modeling data is assigned as post-cast beams and / or post-cast slabs;

[0073] Modeling is carried out based on component type information to generate a building information model.

[0074] Specifically, in the case of identifying and modeling beams, the specific implementation process includes:

[0075] First, establish the BIM model of precast components. Click the beam recognition modal box in the modeling function menu, and extract the information of the beams in the CAD drawing and set the quantity recognition according to the instructions in the modal box content;

[0076] Furthermore, extract the modeling data (data and layers) in the CAD drawing. Through the conversion conditions built in the beam recognition modal box, judge whether there is an overlap in height between the beams to be generated and the precast components that have been arranged, so as to distinguish whether the corresponding data of this part is for cast-in-place beams or post-cast beams; among them, if there is an overlap, it is determined that the modeling data to be processed is the data of post-cast beams, and if not, it is determined that the data to be processed is the data of cast-in-place beams.

[0077] Furthermore, in the case where the recognition object is a slab, the specific operation implementation process is similar to the above process of beams. Those skilled in the art can, according to the above-disclosed content, combine specific variables, and without creative labor, achieve the technical effect of distinguishing and generating cast-in-place slabs and post-cast slabs. Therefore, this is not elaborated in this embodiment.

[0078] In some of the embodiments, the recognition of cast-in-place steel bars and post-cast steel bars is associated with the recognition of the above-mentioned "slab", that is, in the process of modeling and generating a building information model, the steel bars in the cast-in-place slab are allocated as cast-in-place slab bars, and the steel bars in the post-cast slab are allocated as post-cast slab bars;

[0079] In some of the embodiments, in order to meet the requirements of the national consumption quota for prefabricated projects, the precast components, cast-in-place components, and post-cast components in the generated building information model can be independently quantified, priced, summarized, and a visual form can be generated according to the type information.

[0080] It should be noted that the steps shown in the above process or the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order from here.

This system is used to implement the above-mentioned embodiments and preferred implementation manners, and those that have been described will not be repeated.
