Description

Technical Field

[0001] The present invention relates to the fields of construction engineering and industrial digitalization, and in particular to an information processing method for building components. Background Art

[0002] At present, in the field of construction engineering, architectural designers use building information model (BIM) software to perform parametric design of various building components. This is a relatively mature platform and has been widely used. Common BIM software such as Revit stores building component information in a very random and scattered location. The information of structural components such as beams, plates, columns, and walls in the commonly used building information model is stored in multiple locations such as component attributes, two-dimensional plane views, and three-dimensional space models. Since the information storage is too scattered, the information cannot be directly used after being extracted from various locations. Architectural designers need to integrate and process it according to relevant standards or specifications before they can use it. However, some information is hidden inside the model and cannot be directly obtained, making information integration very difficult. Summary of the invention

[0003] In view of this, the present invention aims to propose a method for processing information of building components, so as to solve the problem that it is difficult for building designers to quickly and accurately find the properties of a certain building component in the existing building information modeling software.

[0004] A method for processing information of a building component of the present invention comprises:

[0005] S1, extracting properties of building components according to the existing storage information of building components;

[0006] S2, constructing an attribute table with the extracted attribute name of the building component as the key and the attribute information as the value;

[0007] S3, in the attribute table, adding the newly added attribute or newly added information of the building component under the corresponding key or value, thereby updating the attribute table.

[0008] Furthermore, in S1, the building components include four types: beams, plates, columns, and walls, each building component includes multiple key types, and each key type has multiple key names.

[0009] Furthermore, the key types include structural information, geometric information, reinforcement information and model information.

[0010] Furthermore, the structural information includes the floor information, number information, and structural seismic grade information of the building components.

[0011] Furthermore, the geometric information includes information on the location, shape, and size of the building components.

[0012] Furthermore, the steel bar information includes the number, diameter and spacing information of the steel bars.

[0013] Furthermore, the model information includes wall column model information, wall beam model information and wall body model information.

[0014] Furthermore, in S2, the attribute table includes primary, secondary, and tertiary information tables, wherein the primary information table includes the unique attributes of each building component, the secondary information table includes the default attributes of the building components belonging to each floor and the unique attributes of the corresponding floor, and the tertiary information table includes the default attributes of the building components belonging to the project globally.

[0015] Furthermore, in S2, the priorities of searching the attribute table for the building component attributes are first-level information table, second-level information table and third-level information table from high to low. When the corresponding attribute cannot be found in the previous-level information table, it is searched in the next-level information table.

[0016] The information processing method of building components of the present invention can comprehensively cover the geometry, reinforcement, attributes and other information of components in commonly used building information models and combine with relevant rules specified by professional structural design atlases and specifications to process the information in the model and formulate a key value information table, which covers the precise positioning information of steel bars in the components, professional structural design information, three-dimensional geometric information and other information.

[0017] The information processing method of building components of the present invention improves the existing information processing method of the four structural components of beams, plates, columns and walls in building structures, and is compatible with the basic attributes of general three-dimensional model components, such as component cross-sectional dimensions, component length, component position, etc. On this basis, steel bar component parameters, precise model information, etc. are added, and a unified data structure is used to store the above information. Compared with traditional methods, it can be used for more purposes such as steel bar positioning, steel bar quantity calculation, intelligent design, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] 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.

[0025] 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.

[0026] like Figure 1 As shown, the information processing method of the building component of the embodiment of the present invention includes:

[0027] S1, extracting the properties of the building components according to the existing storage information of the building components.

[0028] The existing storage format of building component information is rather chaotic, with different information stored in different forms, of which only a portion of the attributes are stored in the form of attribute tables. Other forms include tables, schematic diagrams, and even text fonts, graphic line types, filling methods, etc. There are many forms, scattered information, and inconsistent standards, which greatly increases the difficulty of information processing.

[0029] The building component information processing method of this embodiment uniformly uses the attribute table format, and can extract various attributes of building components from other forms of storage information and convert them into a standard, unified attribute table format for storage, which is convenient for searching and calling.

[0030] The building components involved in this embodiment include four types: beams, slabs, columns, and walls. Each building component includes a number of attributes, which can be divided into different types such as structural information, geometric information, reinforcement information, and model information according to their properties.

[0031] S2, constructing an attribute table with the extracted attribute names of the building components as keys and the attribute information as values.

[0032] In this embodiment, each building component may include several key types, namely the above-mentioned structural information, geometric information, reinforcement information and model information, etc., each key type has multiple key names, each key name corresponds to an attribute, and the attribute information of each attribute corresponds to a value, and the storage type of the value may include integer, string, floating point decimal or Boolean, etc. Thus, a tree storage structure of building component type (beam, slab, column, wall) → key type (structural information, geometric information, reinforcement information and model information) → key name → value can be formed.

[0033] The following is a basic property table constructed based on the common properties of all building components:

[0034] Table 1 Basic attribute table

[0035]

[0036]

[0037] In this embodiment, the attribute table may include primary, secondary, and tertiary information tables. The primary information table is an information table for the building components themselves, including the unique attributes of each building component. The secondary information table is a floor information table for each floor, including the default attributes of the building components to which each floor belongs and the unique attributes of the corresponding floor. The tertiary information table is a project global information table, including the default attributes of the building components to which the project belongs globally. The format and content of the primary, secondary, and tertiary information tables are the same. Values ​​that do not exist in a certain primary information table can be represented by null values. For example, for the relevant values ​​of the floor attributes, the primary information table is a null value, while the secondary and tertiary information tables have real values. When searching for the value of a certain key name, first search in the primary information table; when the value corresponding to the key in the primary information table is null, search for the value corresponding to the key in the secondary information table; when the value corresponding to the key in the secondary information table is also null, search for the value corresponding to the key in the tertiary information table. As a result, the division of the attribute table is clearer, and it is faster and more convenient to search for the attributes of the building components.

[0038] S3, in the attribute table, adding the newly added attribute or newly added information of the building component under the corresponding key or value, thereby updating the attribute table.

[0039] At present, the information of building components is stored in different forms in building model software, including attribute tables, tables, schematic diagrams, text fonts, graphic line types, filling methods, etc. Effective information for constructing attribute tables can be extracted from these storage formats. The following takes the extraction of information from different storage formats of four building components, beams, slabs, columns and walls, as examples to illustrate.

[0040] Column components

[0041] like Figure 2 The following is a schematic diagram of the attribute table information of a column component. The valid information that can be extracted from it is as follows (the order corresponds to Figure 2 (in serial number):

[0042] Table 2

[0043] Key Name Value Types Remark Edit Type String Contains column geometry information Column number String The number of this component in the model Column longitudinal reinforcement String Rebar identification information Column corner reinforcement String Rebar identification information Middle reinforcement of side B of column section String Rebar identification information Middle reinforcement of H side of column section String Rebar identification information Column stirrups String Rebar identification information Column stirrup type String Rebar identification information Concrete grade String Project Information Protective layer thickness Integer Structural information Earthquake resistance level Integer Project Information

[0044] like Figure 3 The following is a schematic diagram of information in a plane of a column component. The effective information that can be extracted from it is as follows (the order corresponds to Figure 3 (in serial number):

[0045] Table 3

[0046]

[0047]

[0048] like Figure 4 As shown in the figure, it is another schematic diagram of the information in the plane of the column component. The effective information extracted from it is as follows (the order corresponds to Figure 4 (in serial number):

[0049] Table 4

[0050]

[0051] The information originally stored in the form of fields is processed as follows: based on the reinforcement information in the original commonly used building information model structural column, taking the obtained information "16Φ20" as an example, the meaning of this information is that there are 16 grade 1 steel bars with a diameter of 20 mm distributed in the column section. First, according to the comprehensive information such as the cross-sectional dimensions of 1 and 2, the center positioning point, and the thickness of the protective layer, the specific positions of the 16 steel bars are determined and calculated, and a unique ID number is assigned and stored in the information table. The hoop information of parts 3 and 6 needs to be accurately located by combining the hoop type information in the comprehensive model and the hooped longitudinal reinforcement (ID number acquisition). After processing, the information is stored in the information table.

[0052] like Figure 5 The following is a schematic diagram of vertical information of a column component. The effective information extracted from it is as follows (the order corresponds to Figure 5 (in serial number):

[0053] Table 5

[0054]

[0055]

[0056] like Figure 6As shown in the figure, it is another vertical information diagram of the column component. The effective information extracted from it is as follows (the order corresponds to Figure 6 (in serial number):

[0057] Table 6

[0058]

[0059] like Figure 7 As shown in the figure, it is another vertical information diagram of the column component. The effective information that can be extracted from it is as follows (the order corresponds to Figure 7 (in serial number):

[0060] Table 7

[0061]

[0062] The shapes and positions of the large and small hoops of the plane reinforcement are encrypted according to the vertical height of the structural column and the reinforcement information, and the non-encrypted area information is arranged.

[0063] Beam member

[0064] Take the processing of structural frame (beam) component information in the commonly used building information model as an example. Part of the structural frame (beam) information in the building information model has been used in the form of an attribute table:

[0065] like Figure 8 The following is a schematic diagram of the attribute table information of a beam component. The valid information that can be extracted from it is as follows (the order corresponds to Figure 8 (in serial number):

[0066] Table 8

[0067]

[0068]

[0069] The above commonly used building information model information storage method is not enough to describe the structural performance and reinforcement properties of the structural frame (beam). The structural performance and reinforcement properties of the structural frame (beam) that are not described are divided into two types: in-plane information and transverse information. The longitudinal reinforcement and stirrup representation of the beam can be converted into a string format of the flat construction drawing. The plane information is as follows:
