Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
Referring to fig. 1, the present embodiment provides a conversion method for constructing a BIM model, which includes the following steps:
And S100, responding to a model conversion command, and acquiring a basic BIM model generated by third party software for a target building, wherein the basic BIM model comprises a designed BIM model or an calculated BIM model.
The purpose of this embodiment is to realize model conversion, which converts a design BIM model generated in a design stage or an calculation BIM model generated in a calculation stage into a construction BIM model suitable for an on-site construction production stage. It will be appreciated that the BIM models generated each have different characteristics due to different considerations at different stages. For example, the design BIM model in the design stage can accurately define design intent, space, function and aesthetic aspects, but the direct application of the design BIM model in the construction stage has the defects of incomplete attribute information, lack of measure components in the construction process, non-conforming of component precision to construction requirements, lack of deduction relation and breaking relation among components and the like. The calculation BIM in the calculation stage is mainly used for defining a calculation rule, but the direct application of the calculation BIM model in the construction stage has the defects of excessively simplified components, non-conforming component properties to the construction rule and the like.
For the above reasons, the present embodiment can perform conversion between an existing basic BIM model and a construction BIM model in response to a model conversion command issued by a user. The basic BIM model in this embodiment includes the designed BIM model or the calculated BIM model mentioned above, and in addition, the basic BIM model in this embodiment may also include any other existing type of BIM model, for example, a BIM model generated based on CAD blueprints. The basic BIM model may be generated by using any existing third party BIM modeling software, for example REVIT software, BIMMAKE software, etc., and the embodiment is not limited. On the basis of receiving a model conversion command sent by a user, a basic BIM model generated by third-party software can be directly obtained through a preset interface.
S200, analyzing the basic BIM model to obtain space positioning information related to the target building and first attribute information of all first component members.
The basic BIM model is analyzed, and the graph and the data of all the first component members contained in the basic BIM model are obtained. It will be appreciated that any BIM model is generated based on a target building, with different buildings containing a plurality of different components, such as beams, columns, shear walls, etc., each of which constitutes the target building, i.e. the first component in this embodiment. The space positioning information is used for defining the space position of a target building, and the acquisition of the space positioning information specifically comprises the acquisition of floor information and the acquisition of shaft network information. It will be appreciated that in general, the spatial positioning information is the same in the base BIM model and the construction BIM model. Acquiring first attribute information of the first constituent member includes acquiring a first member attribute, acquiring a first dimension attribute, acquiring a first instance attribute, and acquiring a first member model. The first attribute information is used for representing information such as names, materials, types and the like of the components, for example, the names are columns, the materials are concrete, and the types are 600 multiplied by 600; the first dimension attribute is used for representing the length, width, height and other dimension information of the component; the first instance attribute is used to characterize the application range of the corresponding component, e.g., floor 1 to floor 2; the first build model is a specific three-dimensional shape of the corresponding member. In summary, the first attribute information covers various parameter information and image information in the basic BIM model, and comprehensively reflects all the features of the first component.
S300, determining second attribute information and third attribute information of the target building according to the first attribute information; the second attribute information is attribute information obtained after a part of components already contained in the basic BIM model are subjected to preset format conversion, and the third attribute information is attribute information corresponding to components not contained in the basic BIM model.
This step may include sub-steps S310-S330:
S310, determining a common component contained in the first component and the second component and a new component only contained in the second component according to a second component predefined by a construction BIM model and related to the target building.
The construction BIM model in this embodiment predefines all second constituent elements necessary for the construction of different buildings. As previously described, the Building Information Modeling (BIM) model is designed to lack measure components in the construction process, so that the components in the calculated BIM model are too simplified, and therefore, for the same target building, the second component included in the construction BIM model is more abundant in general type and more accurate in data relative to the first component in the basic BIM model. For members that coexist in the base BIM model and the construction BIM model, the present embodiment is referred to as a common member; for components defined only in the construction BIM model and not in the base BIM model, this embodiment is referred to as an added component.
S320, converting the first attribute information corresponding to the shared component into second attribute information adapting to the construction BIM model.
The first attribute information and the second attribute information are respectively subordinate to different BIM models, and the storage formats of the data lines corresponding to the first attribute information and the second attribute information may be different. Thus, the conversion between the first attribute information and the second attribute information first includes a conversion of the data storage format, converting the data storage format suitable for the underlying BIM model into a data storage format suitable for the construction BIM model. Second, the numerical precision may also be different between the first attribute information and the second attribute information, for example, the numerical precision of the first attribute information is a single-precision floating point type, the numerical precision of the second attribute information is a double-precision floating point type, and so on. Again, the items contained in the first attribute information and the second attribute information may be different, and generally the second attribute information contains more items than the first attribute information. For example, the item "top elevation" in the first attribute information indicates the relative height of the building roof, and may be broken down into two items "top elevation" and "top offset" in the second attribute information, respectively indicating the floor elevation referenced by the building roof and the offset of the building roof relative to the floor elevation. Wherein, the calculation relation between each item in the second attribute information and each item in the first attribute can be preset, so that the numerical value of the corresponding item in the second attribute information can be calculated through the numerical value of the item in the first attribute information. It can be seen that the content of the newly added item in the second attribute information is more suitable for guiding the actual construction process.
Fig. 2 is a schematic diagram showing a mapping relationship between first attribute information and second attribute information according to a first embodiment of the present invention. Taking a rectangular frame column in a budget model (calculation amount BIM model) as an example, the left half of fig. 2 shows a first member attribute, a first type attribute, and a first instance attribute in the first attribute information; the right half shows the second member attribute, the second type attribute, and the second instance attribute in the second attribute information. It can be seen that the second attribute information and the first attribute information have a corresponding mapping relationship, some mapping relationships (such as category, type name, structure type, etc.) are in one-to-one correspondence, and some mapping relationships (such as top elevation, top offset, etc.) are obtained after calculation.
S330, reconstructing the new component based on a preset rule to obtain third attribute information corresponding to the new component and adapting to the construction BIM model.
As previously described, the newly added component is a component that does not appear in the basic BIM model, such as a secondary component, a site temporary component, or the like. The newly added component has corresponding third attribute information whose data storage format, numerical precision, and composition items are generally similar to those of the second attribute information. The item specific value in the third attribute information may be generated according to a default value or may be determined according to a preset algorithm between the common members.
S400, generating the construction BIM model according to the space positioning information, the second attribute information and the third attribute information.
It will be appreciated that the positional coordinates of the construction BIM model are generally consistent with respect to the base BIM model, and thus, the specific location of the construction BIM model can be constructed directly from the spatial location information parsed from the base BIM model. For example, the coordinates of the center point of the construction BIM model are determined according to the axis network information in the space positioning information, and the position coordinates of each floor in the construction BIM model are determined according to the floor information in the space positioning information. After the location is determined, a corresponding member may be further added at the corresponding location.
On the basis of the obtained respective attribute information of the common member and the newly added member, the relevant attributes of all the members constituting the construction BIM model can be determined. Thus, the attribute information of all the components are combined together, and a complete construction BIM model can be obtained.
Through the steps, the conversion from the basic BIM model to the construction BIM model can be realized. The conversion process realized by the embodiment can promote the basic BIM model only having an effect display function or an engineering amount calculating function to a construction BIM model capable of directly guiding actual construction and production, thereby greatly improving the utilization rate of the existing BIM model and simultaneously improving the enthusiasm of enterprises for building the BIM model.
FIG. 3 is a schematic diagram of converting a basic BIM model into a construction BIM model according to an embodiment of the invention. As shown in FIG. 3, the base BIM model on the left may be a design BIM model or a bid budget (calculation) BIM model. The data format of the basic BIM model can be GFC format or Gbp format. The intermediate process of converting the basic BIM model includes parsing GFC data (or Gbp); performing floor shaft network information conversion; converting attribute information of the common components, wherein the attribute information comprises geometric modeling parameterization reconstruction and mapping of parameter information; and finally, reconstructing the project model, namely generating a main body structure and a basic structure according to the common components, and generating newly-added components related to door and window openings, secondary components and the like, so as to obtain the construction BIM shown on the right side of fig. 3. It can be seen that the construction BIM model on the right side in fig. 3 has approximately the same overall structure as the base BIM model on the left side but has more detailed and complete details, so that the actual construction production process can be better guided.
Fig. 4 shows a schematic flow chart of an embodiment of the invention for generating a construction BIM model based on the second attribute information and the third attribute information. As shown in fig. 4, step S600 includes:
s610, determining breaking rules and deduction rules between every two shared components and/or newly added components.
Besides the conversion between the attribute information meets the construction business requirement, the embodiment also needs to rapidly process the position relation between the construction components, such as the supporting relation of the main beam and the secondary beam, so as to meet the business requirement of accurately constructing the BIM model, and accurately judge the positions of the templates and the reinforcing steel bars when the templates are supported and the reinforcing steel bars are placed in the follow-up process. The embodiment provides a construction BIM model deepening business algorithm pertinently so as to automatically solve the buckling and supporting relation between model construction and the segmentation relation of construction flow sections and post-pouring strips to components.
For the deduction and breaking relationship between the components, the present embodiment performs grouping and priority determination according to the properties of the components, as shown in fig. 5. The common member or the newly added member in the present embodiment may be divided into different functional members according to practical functions, including any one of a load bearing member, a base member, a secondary member, a surrounding member, an accessory member, and a decorative member. When determining the deduction/breaking relation, the embodiment firstly judges what kind of functional component the target component belongs to according to the component property; and then determining a deduction/breaking rule according to a preset priority order. In the example of fig. 5, it can be seen that P1 through P8 are divided for a total of 8 priorities. When a deduction/interruption relationship exists between a member with low priority and a member with high priority, the member with high priority is calculated first, and then the member with low priority is calculated.
S620, generating a construction BIM model corresponding to the target building according to the second attribute information, the third attribute information, the breaking rule and the deduction rule.
The construction BIM model obtained through the steps has the service attribute required in the construction stage, meets the dividing requirement of a construction water flowing section and a post-pouring belt, meets the buckling and breaking relation between components, has basically accurate geometric dimensions, and meets the accurate geometric requirement of physical segmentation of a horizontal component beam slab according to the span. The BIM model inherits basic shared information of design and calculation models, rapidly endows construction service attribute and deepening of geometric accurate positions, and can meet service requirements of accurately guiding site construction production.
With continued reference to fig. 6, a conversion device for constructing a BIM model is shown, in this embodiment, the conversion device 60 for constructing a BIM model may include or be divided into one or more program modules, where the one or more program modules are stored in a storage medium and executed by one or more processors, so as to complete the present invention, and the conversion method for constructing a BIM model described above may be implemented.
