Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of building information modeling, and in particular to a BIM beam span modeling and reinforcement information management method and device. BACKGROUND
[0002] In the process of architectural design and construction, BIM (Building Information Modeling) technology has become an indispensable tool, especially in beam member design and reinforcement information management. However, in the case of large beam span and complex cross-section, traditional BIM models have many inconveniences. Especially when viewing the complete beam member model and transferring reinforcement information, traditional methods often result in low work efficiency, information loss and poor communication. Therefore, optimizing the beam member span modeling and reinforcement information management method can help improve the precision and efficiency of architectural engineering design and construction.
[0003] Currently, although BIM software such as Revit provides beam member modeling functions, when dealing with beam members with more than one span, especially in cases involving variable cross-sections, a complete beam is often divided into multiple independent BIM components, resulting in a lack of correlation between models, making it not intuitive and inconvenient to view. In addition, the reinforcement information of the beam member cannot be transferred with the model, and usually requires additional files to be saved and manually entered, which not only increases the workload, but also easily causes information loss or repeated entry problems.
[0004] Therefore, there is an urgent need for a BIM beam span modeling and reinforcement information management method and device that can directly store reinforcement information in beam components and sub-components, avoiding information loss and repeated entry, and improving work efficiency.

[0043] The preferred embodiments of the present application will be specifically described below in conjunction with the drawings, wherein the drawings constitute a part of the present application, and are used to illustrate the principles of the embodiments of the present application, and are not used to limit the scope of the present application.
[0044] Please see Figure 1 The present embodiment provides a BIM beam span modeling and reinforcement information management method, which comprises
[0045] Step S101: splitting the original beam component to generate a plurality of beam span sub-components;
[0046] Step S102: combining the plurality of beam span sub-components according to a preset rule to generate a beam component;
[0047] Step S103: Obtain the centralized reinforcement information and the in-situ labeling information based on the design drawing, and write the centralized reinforcement information and the in-situ labeling information into the beam component and the corresponding beam span sub-component respectively to obtain the beam span BIM model with reinforcement information.
[0048] The method of the embodiment first splits the beam component into multiple beam span sub-components, and merges the sub-components into a complete beam component through a preset rule, thereby ensuring the integrity and relevance of the beam component, so that the user can intuitively view the entire beam component when selecting a single beam span, avoiding the inconvenience of too many spans in the traditional method. Secondly, the reinforcement information is directly stored in the component model, solving the loss problem caused by the inability of reinforcement information to pass with the model. In the model modification and transmission process, the reinforcement information is effectively preserved, thereby reducing the workload of manually entering reinforcement information and improving work efficiency.
[0049] Because when modeling, for the adjacent beam spans on the design drawing without variable cross-section (same cross-section width, cross-section height), a complete beam component model is often directly used for representation when converted by the modeling software or manually modeled and drawn by relevant personnel for the sake of convenience and other factors, but this is not conducive to beam span display and subsequent reinforcement information preservation. As a preferred embodiment, in step S101, the current beam component needs to be split and calculated first to regenerate the beam span component. The following will be described in combination with Figure 2 The above original split implementation process is described in a specific implementation process. As shown in Figure 2 The specific steps include the following steps:
[0050] Step S11: Identify all components intersecting the original beam component, and select the support components that meet the preset beam component calculation business rules from the components to obtain a support component set;
[0051] Step S12: Select one end of the original beam component arrangement path as a reference point, calculate the distance of each support component from the reference point, and sort the support components by distance from near to far to form a sorted support component sequence. It should be noted that if there is no support component at the reference point, the reference point is taken as the starting point of the first beam span sub-component;
[0052] Step S13: Take the coordinate points of the adjacent two support components in the sorted support component sequence as the starting point and the ending point, and generate multiple beam span sub-components that are continuous in space, non-overlapping, and retain the structure attributes of the original beam component to obtain a beam span sub-component set.
[0053] Step S14: Delete the original beam component in the BIM model to avoid model duplication.
[0054] In some implementations, first, all components intersecting with the current beam component to be split (denoted as SplittingBeam) are calculated by the relevant API, and then the intersecting component set that can be used as the beam span support is filtered out according to the beam component calculation business rules, denoted as SupportSet. The beam component calculation business rules define the calculation rules of the civil engineering quantity, the steel reinforcement engineering quantity and the beam span support component judgment related to the beam component, and the calculation rules may be different in different regions.
[0055] Secondly, the support components recorded in the SupportSet set are sorted. Taking an arbitrary end coordinate point of the beam component SplittingBeam layout path as BeamEnd0 (reference point), the distance value of each support component from BeamEnd0 is calculated, and the support components are sorted in ascending order. The sorted support component set is denoted as SortedSupportSet. The original beam component layout path is the spatial extension track of the original beam component in the BIM model (which can be regarded as the overall shape path of the beam component).
[0056] Finally, the coordinate point list of each adjacent support component in SortedSupportSet is taken as the starting point and the ending point of the layout path of the newly generated beam span sub-component, and the relevant API is called to generate a new beam span sub-component, which is added to the newly generated beam span sub-component set. SplittingBeam is deleted to avoid the existence of duplicate component models.
[0057] Further, if BeamEnd0 represents a coordinate point without a support component (i.e., a cantilever end), the starting point of the layout path of the first newly generated beam span component is BeamEnd0, and the rest is unchanged according to the original calculation method (the processing of the other end is the same). The newly generated beam span sub-component set is denoted as SplitBeamSet.
[0058] As a preferred embodiment, in step S102, the plurality of beam span sub-components are merged according to a preset rule to generate a beam part, including:
[0059] determining whether the adjacent beam span sub-components simultaneously satisfy a preset merging condition; wherein the preset merging condition includes: both adjacent ends have supports and are the same component, and both adjacent ends have no support but the ends intersect;
[0060] arranging the adjacent beam span sub-components that satisfy the merging condition in order according to the position in the extension direction of the original beam component, and grouping them into the same beam span set;
[0061] performing a merging operation on all beam span sub-components in the beam span set to generate a beam part.
[0062] As a specific embodiment, as shown in Figure 3 Firstly, it is judged whether the beam span sub-members in the SplitBeamSet can be merged into the same beam component. The calculation judgment basis for merging into the same beam is:
[0063] a. The same member number; wherein the member number is set according to the design drawing, and the embodiment will be different for different modeling specifications, such as may be reflected in the member name prefix, or may be stored in a separate member parameter.
[0064] b. Both adjacent ends have supports and are the same support members, or both adjacent ends have no supports but the ends have intersections;
[0065] If the above conditions a and b are met, the beam span sub-members can be sequentially added to the current BeamSpanSet, wherein the member number should be set according to the relevant design drawing marked content. Since the member number may be reflected in the member name or member parameter according to the requirements of different modeling specifications, it can be obtained according to the actual situation.
[0066] Finally, the beam span sub-members in the set BeamSpanSet are merged by calling the related API to generate the beam component member. Taking Revit as an example, the component type is AssemblyInstance, and the beam component object can be generated by calling the AssemblyInstance.Create() method to pass in the beam span member ID set.
[0067] After the two steps of splitting and merging the original beam members, since the beam component itself does not create its own geometric model, it will not affect the basic display of the original beam span member, and the beam span members belonging to the same beam component can be displayed as a complete component, that is, when a certain beam span member is selected, other beam span members belonging to the same beam component will also be in the selected state. Thus, the model of a beam member can be completely and intuitively represented, solving the technical problems of lack of correlation between models, non-intuitive and inconvenient viewing described in the foregoing.
[0068] As a preferred embodiment, in step S103, the centralized labeling information includes: a centralized labeling reinforcement model name, upper longitudinal reinforcement, lower longitudinal reinforcement, lateral longitudinal reinforcement stirrup and tension reinforcement;
[0069] The in-situ labeling includes an in-situ labeling reinforcement model name, left support reinforcement, right support reinforcement, mid-span reinforcement, lower reinforcement, stirrup and lateral longitudinal reinforcement.
[0070] Specifically, in order to facilitate the analysis of the reinforcement engineering quantity calculation content, the reinforcement information needs to be obtained from the corresponding design drawing.
[0071] In a preferred embodiment, step S103, which involves writing the centralized reinforcement information and the in-situ annotation information into the beam component and the corresponding beam span sub-component respectively to obtain a beam span BIM model with reinforcement information, includes:
[0072] In the BIM platform, extensible data structures are defined for beam components and beam span sub-components respectively; wherein, the data structure includes reinforcement attribute fields corresponding to centralized annotation and in-situ annotation;
[0073] Extract reinforcement attribute values from the design drawings and assign them to the corresponding fields to form reinforcement annotation information;
[0074] The reinforcement annotation information is persistently saved as additional data to the corresponding beam components and beam span sub-components, thereby realizing the association and binding of reinforcement information with the beam component model.
[0075] As a specific example, after the beam span components are split and generated, and the beam parts are created, the reinforcement information can be written into the BIM model for storage. The beam part is also an independent and complete component object, which can support the storage of reinforcement information. The centrally annotated reinforcement information indicates the reinforcement situation of the entire beam, so it can be written into the beam part, while the in-situ annotated reinforcement information indicates the reinforcement situation of a specific beam span, and can be written into the corresponding beam span component model.
[0076] Different BIM software may have different saving methods. Here, we take Revit as an example. After creating a Schema object through the API, defining the corresponding field information and setting the attribute values according to the reinforcement attributes mentioned above, we save it to the beam component and beam span member using Element.SetEntity(). Similarly, if we need to read the relevant reinforcement information from the model later, we can use Schema and Element.GetEntity().
[0077] After the above steps, the reinforcement information has been successfully written and saved to the corresponding BIM model. This solves the current technical problem that reinforcement information cannot be transferred with the model and requires an additional file for saving and recording, which makes it extremely inconvenient and easy to lose when modifying and transferring the model.
[0078] like Figure 4 As shown, this embodiment of the invention also provides a BIM beam span modeling and reinforcement information management device 400, comprising:
[0079] The splitting module 401 is used to split the original beam component into multiple beam span sub-components;
[0080] The merging module 402 is used to merge the multiple beam span sub-components according to preset rules to generate a beam component;
[0081] The information annotation module 403 is used to obtain centralized annotation reinforcement information and in-situ annotation information based on the design drawings, and write the centralized annotation reinforcement information and in-situ annotation information into the beam component and the corresponding beam span sub-component, respectively, to obtain a beam span BIM model with reinforcement information.
[0082] like Figure 5 As shown in the above-described BIM beam span modeling and reinforcement information management method, this invention also provides an electronic device 600, which can be a mobile terminal, desktop computer, laptop, handheld computer, server, or other computing device. The electronic device includes a processor 501, a memory 502, and a display 503.
