Description

Technical Field

[0001] The present invention relates to the technical field of building intelligent analysis, and in particular to a method and system for performing clear height analysis on a building based on BIM technology. Background Art

[0002] In the field of construction, BIM is usually used to simulate building models, so as to conduct intelligent analysis of the building's design structure, strength, lifespan and other information. It is an intelligent means of conducting feasibility studies before building construction. In some current building application scenarios, it is also used for building net height analysis to ensure that under the premise of the existing overall building planning, the design layout is carried out so that the overall building height can meet the design requirements.

[0003] In the existing technical solutions, usually only simple building model planning is carried out. A large building model is built according to the building drawings, and then the interior decoration, fire protection design and other layouts of the building are added layer by layer according to the model. After the addition is completed, it is checked whether the net height of each floor of the building meets the requirements. However, this method is too simple. In actual application, each floor needs to be adjusted one by one. On the other hand, when some net height designs cannot meet the requirements, it is necessary to check each floor to find adjustable space. This is a huge workload and very inconvenient for group buildings and super high-rise buildings. For this reason, a method and system for net height analysis of buildings based on BIM technology are provided. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a method and system for clear height analysis of buildings based on BIM technology, which solves the problem that the prior art solution needs to adjust each floor one by one. On the other hand, when some clear height designs cannot meet the needs, it is necessary to check each floor to find adjustable space. This is a huge workload and very inconvenient for group buildings and super high-rise buildings.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A method for analyzing the net height of a building based on BIM technology, comprising the following steps;

[0006] S1. Data preparation: obtain building drawing information, and then build a BIM model based on the drawing information; then obtain detailed information on design details, which will serve as data support for subsequent data analysis;

[0007] S2, data analysis, first set the analysis parameters, import the design detail data information into the BIM big model established in S1, then apply the BIM big model to analyze it floor by floor, and summarize the analysis results in order of floors, and finally, display the analysis results in the form of models and data;

[0008] S3, application optimization, marks the areas with problems in the data results analyzed by S2, and identifies the problem types. According to the problem types, an optimization solution database is established, and the solution set in the application database is used to screen out suitable solutions. Finally, the application is confirmed through review, and the analysis results are finally confirmed and output.

[0009] Preferably, in step S1, the acquired building drawing information is parametrically decomposed, and the parameters are imported into the BIM model to generate a building model corresponding to the data. At the same time, according to the architectural characteristics of the building, all the architectural design detail information content is summarized and parametrically decomposed, and applied to the subsequent data analysis to set the analysis parameters.

[0010] Preferably, the analysis parameters include total building height, number of building floors, appearance parameters, building type, decoration scheme and fire protection design, among which the total building height, number of building floors, appearance parameters and building type are predetermined schemes, which are directly obtained through the annotation information in the architectural drawings, and the decoration scheme and fire protection design are rough schemes, which can be modified and adjusted according to actual conditions during the actual construction process.

[0011] Preferably, the total height and number of floors of the building roughly determine the average rough height of the building, while the building shape and building type are passive parameters. According to different building shapes, the net height of some floors and the top and bottom floors needs to be imported separately. The building types include tower buildings, slab buildings, and tower and slab combinations. The design requirements of walls, floors, refuge floors, mezzanines and underground structures need to generate and import parameters for determination, so as to be determined at the basic hard condition parameter level.

[0012] Preferably, in the decoration scheme and fire protection design, the parameter data of pipeline installation, indoor ceiling and floor paving on each floor that affect the clear height are set as adjustable types. During actual construction, they can be adjusted according to the actual floor height to meet the clear height requirements. At the same time, for fire protection design, the impact of clear height can be reduced through reasonable layout.

[0013] Preferably, the data analysis process in S2 includes:

[0014] 1. Obtain basic information of BIM model and design requirements. After collecting the information in the early stage, directly import the parameters;

[0015] 2. Match layer by layer according to data information, and automatically match and import detailed parameters of each layer in the entire BIM building model;

[0016] 3. Data collision, obtain the net height of each floor, merge the data through the BIM building model designed in the early stage and the parameters imported in the later stage, intuitively display the model insertion status of various factors affecting the net height on the floor from the model, and display the net height values ​​of each floor from the data level;

[0017] 4. Review the net height of each floor to determine the preset requirements. The net height of each floor is reviewed floor by floor through the intelligent engine, and quickly compared with the preset net height to determine whether it meets the preset requirements. If it meets the requirements, the net height of the floor is directly output and the data is stored. If it does not meet the requirements, the abnormal floors are marked and the data conflicts are analyzed. Then, according to the data conflict items, the database is first traversed to find historical solutions and possible repairs are made. If the repairs can be made, the solutions are output and a question is asked whether to apply them. If applied, they are covered by the solutions. If you do not choose to apply, the abnormalities are marked and output. When there is no result after traversing the database, the network is connected, and the network cases are searched through the intelligent engine, and the corresponding solutions are output. Then the abnormal output is marked and the intelligent search results are hyperlinked for reference when adjusting the subsequent solutions.

[0018] Preferably, the final result of the data analysis will give the final net height statistics and three-dimensional model display of each floor according to the various parameters of the current BIM building model, and mark the floors that are different from the expectations as abnormal. At the same time, the factors affecting the net height of the floor can be understood based on the marked information, which can be used as variable data for later design adjustments.

[0019] Preferably, in the analysis parameter setting process in S2, in addition to importing the data collected in S1, it is also necessary to set the analysis parameters by establishing a clear height calculation rule;

[0020] Total net height; Stotal = S1-H1*N-H2**N;

[0021] Where S1 is the total height of the building, H1 is the thickness of the building floor, H2 is the total thickness of the ceiling decoration, floor tiles and fire protection pipes in the building, and N is the number of building floors;

[0022] Net height of each floor; S floor = S2-H1-H2-H3...-HN;

[0023] Where S2 is the distance between the upper and lower floors of the target floor, and H1 to HN are the thickness of all upper and lower attachments in the building of this floor.

[0024] Preferably, in the analysis parameter setting in S2, when designing the model appearance, different attachments in the floor are colored and distinguished by color.

[0025] Preferably, a system for performing clear height analysis on a building based on BIM technology comprises:

[0026] System framework, which provides a framework for the layout of each functional module in the entire system and is also used for system upgrades and maintenance;

[0027] AI engine, which provides computing power for model design and data analysis, and realizes intelligent model and data generation;

[0028] The data input module is embedded in the system framework and used for data import and parameterized import of design details during BIM model design;

[0029] The data analysis module is the core module of the entire system, and the data merging and analysis relationship built by the AI ​​engine. At the same time, it sets the net height calculation rules to realize the net height calculation of each floor. At the same time, through manual input, custom calculations can be performed for special areas including roofs, basements, refuge floors, etc.

[0030] Visual output module, used to input BIM large model and model data annotation; display the net height value and calculation process of each floor in table form; output the information of un-output net height floors and the reasons for un-calculation;

[0031] The database module is a storage unit designed based on the system framework. It is used to cache BIM model data and store various error types and error solutions to form an error database.

[0032] The communication module is used for network synchronization and downloading of large model infrastructure, and is also used for online search of solutions when analyzing errors.

[0033] The present invention discloses a method and system for analyzing the net height of a building based on BIM technology, which has the following beneficial effects:

[0034] 1. The method of analyzing the net height of a building based on BIM technology establishes a BIM model of the building, imports various detailed information related to the overall building, thereby determining the rough net height of the building, and then imports relevant fixed detailed information. According to the building format and purpose of each floor, a certain degree of differentiated design is adopted, and a certain amount of height differentiation adjustment is made for each floor, so that the net height of each floor of the entire building can meet the demand. Through data parameter import, data analysis is performed, and through differential parameter collision analysis, the problem area is automatically identified, and the problem type of the problem area is marked. By establishing an optimization solution database and providing solutions through database application, adaptive adjustments are made, and finally analysis results are generated. Through this analysis method, the net height demand of the entire building is achieved by adjusting the movable variable data on the premise of meeting the overall impact design requirements, so as to meet the net height design requirements, without the need for manpower to check and adjust the data one by one, thereby reducing the workload.

[0035] 2. This system for clear height analysis of buildings based on BIM technology establishes a core data analysis module and an AI engine. The AI ​​engine provides computing power for BIM model design display and data collision analysis. The data analysis module quickly matches the data information of each floor, and quickly calculates the clear height of each floor based on the pre-input clear height calculation rules, providing data support for subsequent adjustments to floors that do not meet the clear height design. At the same time, the database module is used to store historical model data and compile them into an error database. In the process of BIM building clear height analysis, the error database can automatically generate solutions for simple clear height difference floors, which has an intelligent effect and shortens the rectification time for building clear height design plans.

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] The embodiment of the present application provides a method and system for clear height analysis of buildings based on BIM technology, which solves the problem of existing technical solutions that require individual adjustments to each floor. On the other hand, when some clear height designs cannot meet the needs, it is necessary to check each floor to find adjustable space. This is a huge workload and very inconvenient for group buildings and super high-rise buildings.

[0043] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0044] The embodiment of the present invention discloses a method and system for performing clear height analysis on a building based on BIM technology.

[0045] According to the attached Figure 1-4 As shown, the following steps are included;

[0046] S1. Data preparation: obtain building drawing information, and then build a BIM model based on the drawing information; then obtain detailed information on design details, which will serve as data support for subsequent data analysis;

[0047] S2, data analysis, first set the analysis parameters, import the design detail data information into the BIM big model established in S1, then apply the BIM big model to analyze it floor by floor, and summarize the analysis results in order of floors, and finally, display the analysis results in the form of models and data;

[0048] S3, application optimization, marks the areas with problems in the data results analyzed by S2, and identifies the problem types. According to the problem types, an optimization solution database is established, and the solution set in the application database is used to screen out suitable solutions. Finally, the application is confirmed through review, and the analysis results are finally confirmed and output.

[0049] In step S1, the acquired building drawing information is parametrically decomposed, and the parameters are imported into the BIM model to generate a building model corresponding to the data. At the same time, according to the architectural characteristics of the building, all the architectural design details are summarized and parametrically decomposed, and applied to the subsequent data analysis to set the analysis parameters.

[0050] The analysis parameters include total building height, number of building floors, appearance parameters, building type, decoration plan and fire protection design. Among them, total building height, number of building floors, appearance parameters and building type are predetermined plans, which can be directly obtained through the marked information in the architectural drawings. The decoration plan and fire protection design are rough plans, which can be modified and adjusted according to the actual situation during the actual construction process.

[0051] The total building height and number of floors roughly determine the rough average height of the building, while the building shape and building type are passive parameters. According to the different building shapes, the net height of some floors and the top and bottom floors need to be imported separately. The building types include tower buildings, slab buildings, and tower-slab combinations. The design requirements of walls, floors, refuge floors, mezzanines, and underground structures need to generate and import parameters for determination, so as to be determined at the basic hard condition parameter level.

[0052] In the decoration plan and fire protection design, the parameter data of pipeline installation, indoor ceiling and floor paving on each floor that affect the net height are set as adjustable types. During actual construction, they can be adjusted according to the actual floor height to meet the net height requirements. At the same time, for fire protection design, the impact of net height can be reduced through reasonable layout. This type of data is variable data. When performing net height analysis and design for each floor, the preset net height requirements can be met by changing the variable data.

[0053] The process of data analysis in S2 includes;

[0054] 1. Obtain basic information of BIM model and design requirements. After collecting the information in the early stage, directly import the parameters;

[0055] 2. Match layer by layer according to data information, and automatically match and import detailed parameters of each layer in the entire BIM building model;

[0056] 3. Data collision, obtain the net height of each floor, merge the data through the BIM building model designed in the early stage and the parameters imported in the later stage, intuitively display the model insertion status of various factors affecting the net height on the floor from the model, and display the net height values ​​of each floor from the data level;

[0057] 4. Review the net height of each floor to determine the preset requirements. The net height of each floor is reviewed floor by floor through the intelligent engine, and quickly compared with the preset net height to determine whether it meets the preset requirements. If it meets the requirements, the net height of the floor is directly output and the data is stored. If it does not meet the requirements, the abnormal floors are marked and the data conflicts are analyzed. Then, according to the data conflict items, the database is first traversed to find historical solutions and possible repairs are made. If the repairs can be made, the solutions are output and a question is asked whether to apply them. If applied, they are covered by the solutions. If you do not choose to apply, the abnormalities are marked and output. When there is no result after traversing the database, the network is connected, and the network cases are searched through the intelligent engine, and the corresponding solutions are output. Then the abnormal output is marked and the intelligent search results are hyperlinked for reference when adjusting the subsequent solutions.

[0058] The final result of the data analysis will provide the final net height statistics and three-dimensional model display of each floor based on the various parameters of the current BIM building model. At the same time, the floors that are different from the expectations will be marked as abnormal. At the same time, the factors affecting the net height of the floor can be understood based on the marked information, which will be used as variable data for later design adjustments.

[0059] During the analysis parameter setting process in S2, in addition to importing the data collected in S1, it is also necessary to set the analysis parameters by establishing the clear height calculation rules;

[0060] Total net height; Stotal = S1-H1**N-H2*N;

[0061] Where S1 is the total height of the building, H1 is the thickness of the building floor, H2 is the total thickness of the ceiling decoration, floor tiles and fire protection pipes in the building, and N is the number of building floors;

[0062] Net height of each floor; S floor = S2-H1-H2-H3...-HN;

[0063] Where S2 is the distance between the upper and lower floors of the target floor, and H1 to HN are the thickness of all upper and lower attachments in the building of this floor.

[0064] In the analysis parameter setting in S2, when designing the model appearance, different attachments in the floor are colored and the attachments are distinguished by color.

[0065] A system for analyzing the clear height of a building based on BIM technology, comprising:

[0066] System framework, which provides a framework for the layout of each functional module in the entire system and is also used for system upgrades and maintenance;

[0067] AI engine, which provides computing power for model design and data analysis, and realizes intelligent model and data generation;

[0068] The data input module is embedded in the system framework and used for data import and parameterized import of design details during BIM model design;

[0069] The data analysis module is the core module of the entire system, and the data merging and analysis relationship built by the AI ​​engine. At the same time, it sets the net height calculation rules to realize the net height calculation of each floor. At the same time, through manual input, custom calculations can be performed for special areas including roofs, basements, refuge floors, etc.

[0070] Visual output module, used to input BIM large model and model data annotation; display the net height value and calculation process of each floor in table form; output the information of un-output net height floors and the reasons for un-calculation;

[0071] The database module is a storage unit designed based on the system framework. It is used to cache BIM model data and store various error types and error solutions to form an error database.

[0072] The communication module is used for network synchronization and downloading of large model infrastructure, and is also used for online search of solutions when analyzing errors.

[0073] This method of analyzing the net height of a building based on BIM technology establishes the corresponding main BIM model by acquiring the basic information for establishing a large BIM model, and then determines the rough net height of the building by importing various detailed information related to the overall building, including basic information such as the building type, total height of the building and the number of floors. Then, relevant detailed information is imported, including the special shape structure of the building, such as depressions or protrusions at certain heights of the building, or the necessary channel steel layers, shear walls, load-bearing beams, etc. that affect the specific number of floors when the building reaches a certain height. The above information is fixed and rigid standard information. At the same time, according to the building type and purpose of each floor, a certain degree of differentiated design is adopted, including but not limited to decoration and ceiling decoration, ground process treatment, such as ground The design of bricks, floors and carpets, as well as the fire protection facilities on each floor, can be adjusted according to the net height analysis method. After the design is completed, a certain amount of height differentiation adjustment is made for each floor, so that the net height of each floor of the entire building can meet the requirements. Through data parameter import, data analysis is performed, and through differential parameter collision analysis, the problem area is automatically identified and the problem type of the problem area is marked. By establishing an optimization solution database and providing solutions through database application, adaptive adjustments are made and analysis results are finally generated. Through this analysis method, the net height requirements of the entire building are adjusted on the premise of meeting the overall impact design requirements, so as to meet the net height design requirements by adjusting the movable variable data. There is no need for manpower to check and adjust the data one by one, thus reducing the workload;

[0074] At the same time, the present solution also provides an analysis system, which is applied to the above analysis method. In the system, a core data analysis module and an AI engine are established, and the AI ​​engine provides computing power for BIM model design display and data collision analysis. The data analysis module quickly matches the data information of each floor, and quickly calculates the net height of each floor according to the pre-input net height calculation rules, so as to provide data support for the subsequent adjustment of floors that do not meet the net height design. At the same time, the database module is used to realize the storage of vertical model data, and the data is collected to form an error database. In the process of BIM building net height analysis, the error database can automatically generate solutions for simple net height difference floors, which has intelligent effect, shortens the plan rectification time of building net height design, and has intelligent application.
