Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of material management based on BIM technology, and in particular to a management method for super complex masonry engineering materials based on BIM technology. BACKGROUND

[0002] With the pursuit of architectural art effect of large public buildings being higher and higher, new technologies such as artistic masonry, brick and stone mixed masonry, stone masonry, and brick and stone tile mixed masonry are more used in civil engineering, and the materials of masonry engineering are no longer limited to fired bricks and regular stones, and the masonry method is also more and more complex.

[0003] In the application of various new types of masonry structures, it is not difficult to see that the building design field has shown a trend of using more and more types of masonry materials. For construction units, how to accurately carry out material procurement, inventory management, and match the number of engineering entities is a difficult problem to be solved at present.

[0004] Traditional management method: batch procurement, all kinds of materials are purchased according to the estimated amount of full specifications, and after a certain degree of construction, the approximate law of material consumption is summarized, and repeated procurement is supplemented, and the construction process directly completes one construction section according to the designer's cognition of the effect drawing. Such a management method will have the following defects: 1. sudden discovery of insufficient inventory of certain materials, and too much remaining of certain materials; 2. easy to be denied by designers for artistic effect after masonry, causing rework. SUMMARY

[0005] Therefore, the purpose of the present application is to provide a management method for super complex masonry engineering materials based on BIM technology.

[0006] To achieve the above purpose, the present application provides a management method for super complex masonry engineering materials based on BIM technology, comprising the following steps:

[0007] Constructing a main structure model in BIM based on design drawings;

[0008] Constructing a masonry structure model based on the main structure model, dividing the masonry structure model into a plurality of masonry unit models, and simulating the masonry unit models, loading a material library corresponding to the masonry unit models from BIM, generating a unique code for each masonry unit model according to the material library, and generating a code table corresponding thereto;

[0009] Extracting the corresponding masonry unit model from the main structure model in turn based on the code table, extracting the material category corresponding to each masonry unit model, and writing the material category corresponding to the masonry unit model into the directory of the code table, forming a material table;

[0010] Based on the material list, write the material information corresponding to the material category into the corresponding directory. Using the set rules as the extraction criterion, merge the items in the material list that have the same set rules to form a procurement list, and output the procurement list.

[0011] Based on the procurement list, the procured materials are classified according to the procurement list. At the same time, an electronic tag is constructed for each material using the code corresponding to each masonry unit model. The materials are classified and stored through the electronic tags. The electronic tags are then uploaded to the control terminal.

[0012] The simulation-processed masonry unit model, with the masonry structure model as the main body, is sequentially converted into two-dimensional renderings. The two-dimensional renderings are then input into the masonry team, while the material usage is output and the inventory is synchronized.

[0013] VR technology is used to project physical models onto the site for comparison and inspection.

[0014] Furthermore, the scope of the masonry structure is determined based on the design drawings, namely the top elevation, bottom elevation, component boundaries, and whether there are backing walls, beams, or columns on the back of the masonry.

[0015] Establish a main structural model based on the structural construction drawings.

[0016] Furthermore, a masonry structure model is constructed based on the design renderings and the main structure model. An artistic effect model is then constructed within the masonry structure model based on the design renderings. Based on the constructed artistic effect model, the artistic effect model is divided into several masonry unit models.

[0017] Furthermore, each masonry unit model is coded according to material type, color, and size specifications.

[0018] Furthermore, based on the requirements of the masonry structure specifications and the masonry construction process, the material categories corresponding to each masonry unit model are extracted, and a material calculation and statistical quantity extraction table is established based on the aforementioned coding table to form a material table.

[0019] Furthermore, items with the same set rules in the material list are merged using the set rules as the extraction criterion, and a set percentage of loss is added to the final quantity of each material to form a procurement list.

[0020] Furthermore, the two-dimensional rendering is derived from the artistic effect model by meshing the design rendering, and the two-dimensional rendering has the effect of meshing.

[0021] Furthermore, the masonry team prepares documents according to the requirements of masonry structure specifications and masonry construction technology, and uses daily estimated progress and gridded two-dimensional renderings to predict the material demand for the day. When materials are issued from the warehouse, the electronic tags on the materials are scanned and uploaded to the control terminal. The control terminal performs reverse engineering based on the received electronic tags and the encoding table. The BIM model uses the reverse engineering results from the control terminal to annotate multiple corresponding masonry unit models on the masonry structure model. The annotated multiple masonry unit models are output to obtain a real-time dynamic model based on the construction progress. At the same time, the control terminal synchronizes the received electronic tags with the corresponding issuance quantity and the dynamic model, and presents the progress of the materials used that day in the dynamic model according to the gridded effect.

[0022] Furthermore, during the actual model comparison check: based on the dynamic model provided by the control terminal, VR projection technology is used to conduct a gridded actual model comparison on site to promptly detect whether the masonry effect is consistent with the model.

[0023] The gridded model is presented to the masonry team in a two-dimensional format. The team's daily progress is also predicted based on the number of grid cells in the model, thus determining the daily material requirements. BIM builds a real-time dynamic model based on the outbound data fed back from the control center, synchronizing material usage with the progress of the actual project. The material usage for the day is then presented in the model according to the gridded effect.

[0024] Using VR technology to project physical models on-site for comparison and inspection: A real-time dynamic model is built based on the materials used the previous day. Using VR projection technology, a gridded model is compared on-site to detect whether the masonry effect is consistent with the model. If the masonry materials used by the team are inconsistent with the corresponding coded materials in the gridded model, the deviation can be corrected in time to ensure that the masonry effect matches the designer's rendering.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Reference Figure 1 This invention provides a method for managing materials in ultra-complex masonry engineering based on BIM technology, comprising the following steps:

[0030] Obtain on-site measurement data for wall construction, and construct the main structural model in BIM based on the measurement data;

[0031] A masonry structure model is constructed based on the main structure model, and the masonry structure model is divided into several masonry unit models. The masonry unit models are simulated, and the material library corresponding to the masonry unit model is loaded from BIM. A unique code is generated for each masonry unit model according to the material library, and a corresponding generation code table is generated.

[0032] Based on the coding table, the corresponding masonry unit models are extracted sequentially from the main structure model, and the material category corresponding to each masonry unit model is extracted. The material category is written into the directory corresponding to the masonry unit model in the coding table to form a material table.

[0033] Based on the material list, write the material information corresponding to the material category into the corresponding directory. Using the set rules as the extraction criterion, merge the items in the material list that have the same set rules to form a procurement list, and output the procurement list.

[0034] Based on the procurement list, the procured materials are classified according to the procurement list. At the same time, an electronic tag is constructed for each material using the code corresponding to each masonry unit model. The materials are classified and stored through the electronic tags. The electronic tags are then uploaded to the control terminal.

[0035] The simulation-processed masonry unit model, with the masonry structure model as the main body, is sequentially converted into two-dimensional renderings. The two-dimensional renderings are then input into the masonry team, while the material usage is output and the inventory is synchronized.

[0036] VR technology is used to project physical models onto the site for comparison and inspection.

[0037] Furthermore, the scope of the masonry structure is determined based on the on-site measurement data of the masonry wall, namely the top elevation, bottom elevation, component boundaries, and whether there are lining walls, beams, or columns on the back of the masonry.

[0038] A main structural model is established based on the measurement data and the structural construction drawings.

[0039] Furthermore, a masonry structure model is constructed based on the design renderings and the main structure model. An artistic effect model is then constructed within the masonry structure model based on the design renderings. Based on the constructed artistic effect model, the artistic effect model is divided into several masonry unit models.

[0040] In the above, different masonry unit models have different color schemes, different types of materials, and different areas of occupation in the artistic effect model, and different masonry unit models contain the following key information: the area occupied by different types of materials and the area occupied by materials of different color schemes within the same material.

[0041] In the above, the artistic effect model is meshed according to the design rendering, and each mesh area is represented as a masonry unit model.

[0042] Furthermore, each masonry unit model is coded according to material type, color, and size specifications.

[0043] Furthermore, based on the requirements of the masonry structure specifications and the masonry construction process, the material categories corresponding to each masonry unit model are extracted, and a material calculation and statistical quantity extraction table is established based on the aforementioned coding table to form a material table.

[0044] Furthermore, using established rules (such as material rules, or first dividing materials into several categories according to material rules, and then further dividing them by specific material information) as the extraction criterion, items with the same established rules in the material list are merged, and a set percentage of loss is added to the final quantity of each material to form a procurement list.

[0045] Furthermore, the two-dimensional rendering is derived from the artistic effect model by meshing the design rendering, and the two-dimensional rendering has the effect of meshing.

[0046] Furthermore, the masonry team prepares documents according to the requirements of masonry structure specifications and masonry construction technology, and uses daily estimated progress and gridded two-dimensional renderings to predict the material demand for the day. When materials are issued from the warehouse, the electronic tags on the materials are scanned and uploaded to the control terminal. The control terminal performs reverse engineering based on the received electronic tags and the encoding table. The BIM model uses the reverse engineering results from the control terminal to annotate multiple corresponding masonry unit models on the masonry structure model. The annotated multiple masonry unit models are output to obtain a real-time dynamic model based on the construction progress. At the same time, the control terminal synchronizes the received electronic tags with the corresponding issuance quantity and the dynamic model, and presents the progress of the materials used that day in the dynamic model according to the gridded effect.

[0047] Furthermore, during the actual model comparison check: based on the dynamic model provided by the control terminal, VR projection technology is used to conduct a gridded actual model comparison on site to promptly detect whether the masonry effect is consistent with the model.

[0048] In the above, a table is created to detail the specific specifications and quantities of materials. Based on the current specifications for masonry structures and the masonry construction requirements applicable to this project, a table is created to extract the calculated and statistical quantities of materials. A certain percentage of loss is added to the final quantity of each material to ensure sufficient material usage.

[0049] During warehousing, each type of material is categorized and stored, with its own electronic inventory information tag created and uploaded to the control terminal. A designated person is responsible for inventory management. When materials are retrieved, the electronic tag is scanned using a barcode scanner, and the scanned tag is transmitted to the control terminal in real time. Scanning allows for real-time updates and inventory viewing; this operation is synchronized with the control terminal, which then performs the reverse decoding operation.

[0050] When extracting material categories from a masonry structure model, this application uses a gridded approach based on the design renderings. The materials used in each grid area are directly displayed, and each material is coded according to its type, color, and size. This ensures the model design meets design requirements. Furthermore, the coded table provides accurate and error-free information for the subsequent procurement process.

[0051] The gridded model is presented to the masonry team in a two-dimensional format. The team's daily progress is also predicted based on the number of grid cells in the model, thus determining the daily material requirements. BIM builds a real-time dynamic model based on the outbound data fed back from the control center, synchronizing material usage with the progress of the actual project. The material usage for the day is then presented in the model according to the gridded effect.

[0052] Using VR technology to project physical models on-site for comparison and inspection: A real-time dynamic model is built based on the materials used the previous day. Using VR projection technology, a gridded model is compared on-site to detect whether the masonry effect is consistent with the model. If the masonry materials used by the team are inconsistent with the corresponding coded materials in the gridded model, the deviation can be corrected in time to ensure that the masonry effect matches the designer's rendering.

[0053] Reference Figure 2 , Figure 2 The renderings of this application are provided, from Figure 2 It can be seen that ultra-complex masonry projects not only vary in specifications but also in color. If meticulous management is not carried out, the patterns and colors will not match the designer's design during the construction process, affecting the overall effect. Figure 3 Dynamic model diagrams for different periods are provided. Strict management of outbound shipments is implemented according to the schedule. Outbound shipments are scanned, and the control end verifies and reverse-engineers the data. The dynamic model is marked and extracted in BIM. VR projection technology is used to compare the gridded physical model on site and promptly detect whether the masonry effect is consistent with the model. If the masonry materials used by the team are inconsistent with the corresponding coded materials in the gridded model, the deviation can be corrected in time to ensure that the masonry effect matches the designer's rendering.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
