Description

Technical Field

[0001] The present invention relates to the field of construction, and in particular to a method for generating steel bar information of a building component. Background Art

[0002] At present, in the design stage, architectural designers use building information model (BIM) software to perform parameterization of various building components. This is a relatively mature platform that is currently widely used. However, when it comes to structural design and steel bar design, designers can only input digital information of the steel bar flat design parameters of building components, and cannot generate specific steel bar entities. In the construction stage, construction cutting and budgeting personnel must re-model, input parameters, and estimate the amount of steel bars in the cutting software according to the design drawings, and cannot use the information generated in the structural design stage.

[0003] The lack of steel bar entity information in the design phase and the incompatibility of steel bar information processing between the design phase and the construction phase have led to a series of problems in the construction phase cutting software, which has become the main bottleneck restricting the development of the digital steel bar industry chain. These problems are reflected in the following aspects: ① Due to the non-standard design of the drawings, the design drawings cannot be directly imported into the sample calculation software; ② There are many versions of steel bar sample software but they are not mature, and steel bar sample is still mainly manual; ③ The design software and steel bar sample software cannot realize data sharing, and manual input is required, which is time-consuming, labor-intensive and error-prone; ④ There are large differences in design and processing standards in different countries or regions, and it is difficult for information systems to achieve compatibility; ⑤ The visualization and traceability of the processing process cannot be achieved. The lack of informationization in the steel bar processing process makes it difficult for technicians to visualize the processing process and progress, which is inconvenient to work, and the statistical workload is large and not accurate enough. Summary of the invention

[0004] In view of this, the present invention aims to propose a method for generating steel bar information of building components. Starting from the currently more mature design link, the building information is parametrically designed and processed to solve the most critical steel bar entity generation and statistical problems, break through the information barriers between the design link and the construction link, and give full play to the advantages of digitization and informatization in the steel bar industry chain.

[0076] The description of the embodiments of this specification should be combined with the corresponding drawings, which should be considered as part of the complete specification. In the drawings, the shape or thickness of the embodiments may be enlarged and indicated for simplification or convenience. Furthermore, the parts of each structure in the drawings will be described separately. It is worth noting that the elements not shown in the drawings or not described in words are in a form known to ordinary technicians in the relevant technical field.

[0077] The description of the embodiments herein and any reference to directions and orientations are only for the convenience of description and are not to be construed as any limitation on the scope of protection of the present invention. The following description of the preferred embodiments may involve combinations of features, which may exist independently or in combination, and the present invention is not particularly limited to the preferred embodiments. The scope of the present invention is defined by the claims.

[0078] The embodiment of the present invention provides a method for generating steel bar information of building components, which can be implemented as a plug-in of existing BIM (Building Information Modeling) software. At present, the locations where BIM software such as Revit stores basic geometric information of building components and steel bar parameter information are very randomly scattered. For example, Revit stores plate reinforcement information, and its steel bar parameters are directly stored in the parameter table of the plate component, while the position information needs to be extracted from the plan view of the plate reinforcement; for another example, the reinforcement information of shear wall column, its steel bar parameters are stored in the parameters of the shear wall component and the wall column component, and the longitudinal reinforcement arrangement mode of the wall column needs to be extracted from the plan view of the wall column reinforcement, and which longitudinal reinforcement arrangement mode of each wall column is applied is not directly corresponding, but requires the identification of the wall column graphics to correspond. Therefore, the method for generating steel bar information of the building component of the embodiment of the present invention can be used as a plug-in form to realize the digital processing process of building information based on existing BIM software (including but not limited to Revit) and used for the generation of steel bar information of building components, completing the smooth transition from the design stage to the construction stage. Below, this embodiment specifically introduces the method of the present invention in the form of a Revit plug-in:

[0079] like Figure 1 and Figure 3 As shown, the method for generating steel bar information of building components in this embodiment includes:

[0080] S100: construct a parameter table including first-category parameter information of all building components, wherein the first-category parameter information includes basic geometric information of the building components themselves.

[0081] This step mainly provides a data export plug-in for existing BIM software, which is used to collect and export parameter information of building components.

[0082] After being sorted by the data export plug-in, there is a parameter table for the project as a whole, for each floor, and for each component ("component" means "building component", the same below). Each parameter table is stored in a dictionary structure with the "parameter name" string as the index. When looking for a parameter of a component, first look for the parameter name in the parameter table of the component. If it is not found, look for it in the parameter table of the floor where the component is located. If it is not found, look for it in the parameter table of the project as a whole. Generally speaking, the default parameters of various components are stored in the global parameter table of the project. The parameters missing in each component, or the default parameters consistent with most components, are all in the global parameter table.

[0083] Table 1 below lists the common first-category parameter information for various building components:

[0084]

[0085]

[0086]

[0087]

[0088] Table 1

[0089] Except for Revit, plug-ins for other BIM software must be developed on the development platform provided or supported by the software and run within the software.

[0090] The data files exported by each BIM software plug-in should follow a unified format.

[0091] S200, supplementing the second type of parameter information of the building component in the parameter table, wherein the second type of parameters includes setting parameter information for generating reinforcement rules of the building component.

[0092] This step mainly provides a rebar generation setting program with a graphical interactive interface for users to operate. Users can also input some parameter information for generating rebar rules, that is, the second type of parameter information, which involves the process and specific conditions selected for design and construction. It is worth noting that this part of the parameters is not included in the BIM software, but it is very important in the process of collective processing of building components and generating rebars.

[0093] Table 2 below lists the common second-category parameter information for various building components:

[0094]

[0095] Table 2

[0096] S300: Generate reinforcement information of the building component according to the parameter table.

[0097] This step mainly provides a steel bar generation program, which is used to process the parameter table containing the first type of parameter information and the second type of parameter information that has been exported in the previous steps. By traversing all the building components multiple times, some processing is performed each time, and the results obtained can be applied to the next traversal, and finally the generated steel bar information is obtained.

[0098] Table 3 below lists the processing steps for each traversal:

[0099]

[0100] Table 3

[0101] As shown in the table above, there are seven traversal processes in total, specifically:

[0102] S310: construct a classification component list according to the parameter information in the parameter table.

[0103] like Figure 4 As shown in the figure, in the first traversal, the component parameters are imported from the file, a parameter table is established, and the original geometric shape of the component is obtained by using the parameters related to the position, rotation, and geometry of the component. At the same time, the components need to be placed in the component list of the type, such as beams, columns, slabs, basement exterior walls, shear walls, etc., to form a classified component list.

[0104] S320: Detect geometric collision relationships among the building components according to the classified component list, and construct a related component list for each building component.

[0105] like Figure 5 As shown, in the second traversal, the components in the various component lists are checked for geometric collision relationships between the various components according to the original modeling range of the components, and the various components related to each component are put into the various related component lists.

[0106] S330, calculating the relationship model between the building components according to the related component list to obtain the accurate geometric shape of the building components;

[0107] The third traversal calculates the types of related relationships between components and the precise geometric shapes of the components based on the various related component lists of each component and the original geometric shapes of the components. The following processing needs to be carried out strictly in order, because the component relationships processed later need to use the component relationships obtained earlier; the geometric shape calculations used later need to use the previous geometric shape calculation results.

[0108] Table 4 below lists the processing of the third traversal in order of priority:

[0109]

[0110] Table 4

[0111] Among them, steps b and g mentioned that the relevant columns and beams can form several node types according to geometric relationships. Except for a few cases such as cantilever beams, both ends of all beams must be one of these node types. The concept of node type is very critical in the subsequent traversal steps such as anchorage and segmentation of longitudinal reinforcement of beams and columns. The component types, primary and secondary relationships, and judgment relationships of these node types are shown in Table 5:

[0112]

[0113] Table 5

[0114] For bg1, i.e., the row with the node name "core area" in Table 5, for example, the Z-axis ranges of beams A and B overlap, and the Z-axis ranges of beams B and C overlap. Then, even if beams A and C do not overlap, beams A, B, and C can still be considered to be in the same core area node. For another example, the Z-axis ranges of beams A and B overlap, and the Z-axis ranges of beams C and D overlap, but the Z-axis ranges of beams A and C, beams A and D, beams B and C, and beams B and D do not overlap. Then beams A, beams B, beams C, and beams D cannot be considered to be in the same core area node.

[0115] For bg2, that is, the row in Table 5 with the node name "node in column", the principle is the same as that of bg1.

[0116] In addition, steps a, d, e, g and h in Table 3 mention that components of the same type that meet certain standards can form component relationships. All components must be in a certain set of component relationships, even if there is only one component in this set of component relationships. For example, there can be only one span beam in a set of full-length spans, and there can be only one plate in a set of same-layer plates. The concept of component relationship is very critical in the subsequent traversal steps such as the connection of longitudinal reinforcement. The types of component relationships and judgment conditions are shown in Table 6:

[0117]

[0118] Table 6

[0119] S340, generating corresponding reinforcement parameters according to the precise geometric shape of each building component.

[0120] like Figure 6 As shown, in the fourth traversal, the reinforcement parameter information string of each component is parsed to generate independent reinforcement information for each component. The reinforcement parameters of the component, the generated reinforcement type, etc. can be referred to Table 1. The independent reinforcement generated by the analysis is stored in two lists. The reinforcement that may be connected with the same type of reinforcement in other components is stored in the longitudinal reinforcement list. For example, if the upper longitudinal reinforcement, lower longitudinal reinforcement, and lateral longitudinal reinforcement of each span beam of a set of full-length beams are in the corresponding position and have the same grade and diameter, then these reinforcements can be connected and need to be processed in the subsequent traversal steps; the reinforcement that cannot be connected with the reinforcement in other components is stored in the stirrup reinforcement list, such as beam stirrups, beam horizontal reinforcement, beam vertical reinforcement, etc., and solid reinforcement can be directly generated in the subsequent traversal steps.

[0121] S350, processing the steel bar connection across multiple building components according to the related component list of each building component and the steel bar parameters, and generating solid steel bars.

[0122] like Figure 7As shown, in the fifth traversal, according to the various related component lists of each component, the independent longitudinal reinforcement list of the component is searched, and the independent longitudinal reinforcement list of its related components is searched two by two, and the independent longitudinal reinforcements are judged whether they are geometrically related and have the same grade and diameter. Those that meet the conditions can be merged. Regardless of whether the independent longitudinal reinforcement can be merged, solid longitudinal reinforcement needs to be established at this time. Each solid longitudinal reinforcement can include information of one or more original independent longitudinal reinforcements. Solid longitudinal reinforcement is not stored in the component, but in the component relationship such as full-length beam, same-layer plate, and same-face wall, because solid longitudinal reinforcement often spans multiple components, and the spanned multiple components generally must come from multiple components in the same full-length beam, same-layer plate, and same-face wall.

[0123] S360, anchor and segment each solid reinforcement according to the list of related components.

[0124] The sixth traversal is to find the related components of the components where the first and last sections of each solid steel bar are located. According to the component type, node type, and component set graph of the first and last sections of the solid steel bar, the multiple anchoring methods of each solid steel bar are judged in order of priority whether they are reasonable, and the first reasonable anchoring method is selected. The above process is schematically shown in Table 7:

[0125]

[0126] Table 7

[0127] After the above processing, that is, after the anchoring processing, the actual length of the solid steel bar is obtained. For the components through which the solid steel bar passes, each component allows different types of solid steel bars to be segmented in certain areas. For multiple solid steel bars of the same type, each component requires that these solid steel bars need to be segmented in batches in different areas.

[0128] S370, determining and generating the reinforcement information of each building component according to the result of S360.

[0129] This step is mainly to export the component data and solid reinforcement data obtained in the previous steps.

[0130] The exported component data includes information exported from the BIM software, such as the component ID, component type, component floor, etc.; it also includes the component-related component list, node information, contact information, precise geometric modeling information, etc. generated by the first, second, and third traversals.

[0131] Solid reinforcement includes stirrups / tension bars generated by the fourth traversal, and longitudinal bars generated after connection, anchorage, and segmentation in the fifth and sixth traversals. Here, all solid reinforcements are given an ID as a unique identification number for the solid reinforcements.

[0132] The exported data of solid steel bars include ID, steel bar type, component, diameter, grade, vertex coordinates of each segment, bending radius of each segment, etc.

[0133] Previously, the relationships between building components such as columns, beams, slabs, and walls were mainly defined by atlases, text descriptions, and conventions. These methods were relatively scattered, vague, qualitative, and intuitive, lacking overall considerations, precision, quantification, and procedural judgments. Describing the relationships between components in a digital way is the key to these processing steps.

[0134] In addition, for the exported component data and solid reinforcement data, a visualization and quantity calculation program with a three-dimensional graphical interactive interface can be provided. The program can generate a model based on the component data and solid reinforcement data for users to browse, and the program can count the solid reinforcement information data.

[0135] Since the exported component data contains the component ID and reinforcement ID, users can directly enter the ID to accurately locate the specified component or solid reinforcement and view its model and detailed data.

[0136] Since the exported component data includes the component's floor information and component type information, users can display or hide component models by floor or component type.

[0137] Since the exported solid reinforcement data includes the reinforcement type and the component information, users can display or hide the solid reinforcement model by reinforcement type; when the component is displayed or hidden, the reinforcement model can also be displayed or hidden accordingly.

[0138] The statistical steel bar information includes the steel bar model code, the component type to which the steel bar belongs, the steel bar schematic diagram, the steel bar diameter, the steel bar grade, the number of steel bars of the same type, the total weight of steel bars of the same type, etc. Among them, the component type to which the steel bar belongs, the steel bar diameter, and the steel bar grade are directly included in the physical steel bar data. The steel bar model code and the steel bar schematic diagram are directly calculated from the vertex coordinates and bending radius of each segment in the physical steel bar data. The number of steel bars of the same type and the total weight of steel bars of the same type are calculated by the statistical accumulation of the exported physical steel bar data.

[0139] In summary, the method of the embodiment of the present invention is specifically introduced in the form of a plug-in to describe how to apply the method of the embodiment of the present invention to BIM software to achieve digital improvement of the construction process, especially the generation of steel bar information. However, those skilled in the art understand that other implementation methods based on the method of this embodiment also fall within the scope of protection of the present invention.

[0140] In summary, the method for generating steel bar information of building components in the embodiment of the present invention provides a digital and information-based data processing method between the design stage and the construction stage, which can be used to unify the data format and transmit it between software and between upstream and downstream, avoiding the relevant personnel at each stage from spending a lot of time and energy to rebuild the steel bar model, and ensuring the synchronization of the steel bar model information at the upstream and downstream stages.

[0141] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
