[0002] Building Information Modeling (BIM) is a digital tool used in engineering design, construction, and management. The core of BIM is to establish a virtual three-dimensional model of the building project and use digital technology to provide the model with a complete building project information library that is consistent with the actual situation. At present, the traditional BIM family library remains at the static component level, generally including categories such as building columns, doors, windows, curtain walls, railings, stair ramps, elevators, etc. At the same time, there is also a construction family library, which contains static information such as construction equipment used in construction, components in the construction process, and components after forming.

[0003] The existing traditional static family library cannot provide a dynamic construction process model containing multiple process steps, and the construction process is crucial to building construction. Therefore, how to build a dynamic construction process model that can provide the construction process steps of each building is crucial to the standardization of the construction field.

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] In the present invention, the terms "first", "second", etc. (if any) in the present invention and the accompanying drawings are used to distinguish similar objects but not necessarily to describe a specific order or sequence.

[0023] Figure 1 A flowchart of a method for constructing a dynamic construction process family library based on BIM provided by an embodiment of the present invention. Figure 1 , combined with Figure 2-Figure 3 , the method for constructing a dynamic construction process family library based on BIM in this embodiment is described in detail. Figure 1 , the method includes operations S1 to S5.

[0024] Operation S1, creating geometrical primitives of a plurality of construction process steps required for constructing any building body in the target building under a first construction type, where the first construction type is building construction, building repair or building demolition.

[0025] For any type of target building, it contains a large number of building bodies, such as buildings, structures, etc. The completion of each building body requires multiple construction process steps, and each construction process step is represented by a corresponding geometric primitive. Taking the use of Revit software to establish a dynamic construction process family library based on BIM in this embodiment as an example, the drawing of construction process steps is essentially the establishment of families in Revit. RevitAPI provides several classes such as FamilyManager, FamilyType, FamilyParameter, etc. to manage family types and family parameters. There are five common drawing methods for Revit families, including stretching, fusion, rotation, lofting, lofting fusion, etc. In this embodiment, these five common drawing methods are used to create geometric primitives for each construction process step, and one or more methods of moving, rotating, mirroring, and copying are used to draw and adjust the created geometric primitives.

[0026] Operation S2, filtering and obtaining the construction parameterization information of each construction process step and adding it to the corresponding geometric primitives.

[0027] In this embodiment, the construction parameterized information includes text information of the construction process and / or a three-dimensional animation of the construction process, and includes a construction process acceptance picture. Preferably, the construction parameterized information also includes text information of the construction process, a three-dimensional animation of the construction process, a construction process acceptance picture, a two-dimensional graphic of the corresponding entity, and other parameterized information, such as Figure 3 Other parameterized information includes, for example, the names of the relevant parties (construction party, construction party, subcontractor, supervision party, government responsible unit, material supplier, etc.), direct construction personnel and their contact information, process in-depth design personnel and their contact information, construction site structure detection information, construction site structure disease information, construction site cultural value information, etc.

[0028] After the geometrical primitives of the construction process steps are created, the three views thereof are automatically extracted, size parameters are marked, a two-dimensional graphic of the corresponding entity is formed, and it is transmitted to the corresponding database, for example, through the secondary port developed by the C# programming language.

[0029] For the construction process text information and / or construction process 3D animation, the online integration method is to crawl the construction process text information and / or construction process 3D animation related to the construction process steps on the network through Python crawler; the offline integration method is to directly receive the construction documents and / or actual construction 3D animation related to the construction process steps stored in other terminals, where the construction documents are currently books, construction process deepening design documents, etc. that are digitized and stored in the other terminals, and the actual construction 3D animation is an animation stored in the other terminals formed by observing the actual construction process steps and drawing with reference to the existing construction process deepening design drawings. The construction process acceptance pictures are the staged acceptance photos taken from the construction site terminal.

[0030] Specifically, for the construction process text information, for example, a Python graphic crawler is used to crawl all the text information describing the construction process steps on the Internet, and automatically filter out the construction process text descriptions that meet the requirements according to the set conditions, directly receive the construction documents related to the construction process steps stored in other terminals, and transmit the filtered and received construction process text information to the corresponding database.

[0031] For the three-dimensional animation of construction process, for example, a Python video crawler is used to crawl all the image animations describing the construction process steps on the Internet, and automatically filter out the qualified construction process image animations according to the required conditions, directly receive the actual construction three-dimensional animation related to the construction process steps stored in other terminals, and transmit the filtered and received construction process three-dimensional animation to the corresponding database.

[0032] For the construction process acceptance pictures, the relevant process masters responsible for the site take pictures of the on-site construction process phase acceptance through the on-site terminal (such as a mobile phone) and upload them. In this embodiment, the pictures uploaded by the on-site terminal are directly received as construction process acceptance pictures and uploaded to the corresponding database.

[0033] For other parametric information, it is integrated and standardized and then uploaded to the corresponding database. Further, for example, all the construction parametric information is mapped to the geometric primitives corresponding to different construction process steps in the form of C# calling functions.

[0034] Operation S3, setting the start time node and the end time node of each geometric element based on the start time interval and the end time interval between multiple construction process steps, and obtaining a first construction process parameterized model of any building body to execute each construction process step according to a preset timing.

[0035] Preferably, in operation S3, any construction process step among the multiple construction process steps is used as a reference step, and the start time node and end time node of the geometric elements of each other construction process step are set based on the start time interval and end time interval between each other construction process step and the reference step.

[0036] Specifically, for example, a calling function containing a time interval is written in C# language to call construction process steps of different time sequences. By controlling the start time nodes of two construction process steps to be consistent, two construction processes that start at the same time can be realized. By controlling the time interval n between the start time nodes of the two construction process steps, two construction processes that start in sequence can be realized, and it is ensured that the start time interval is n, and n is a non-negative number. By controlling the end time nodes of the two construction process steps to be consistent, two construction processes that end at the same time can be realized. By controlling the time interval m between the end time nodes of the two construction process steps, two construction processes that end in sequence can be realized, and it is ensured that the end time interval is m, and m is a non-negative number. By controlling the start time node of one construction process step and the end time node of another construction process step to be consistent, it is possible to start the next construction process immediately after one construction process ends. By controlling the time interval j between the end time node of a construction process step and the start time node of another construction process step, two construction processes can be carried out in sequence, and the interval time is guaranteed to be j. When j is a positive number, it means that the next process starts after the interval time |j| after the end of the previous process. When j is a negative number, it means that the next process starts after the interval time |j| before the end of the previous process. That is, the two processes have parts that are carried out at the same time, and the time they are carried out at the same time is |j|. Different construction process timing relationships connect different construction process step parameterized models in the same construction process parameterized model in series to form a logical relationship.

[0037] In this embodiment, for any building, the construction process parameterized model finally obtained is as follows: Figure 3 As shown, each parametric 3D model of construction technology not only needs to include the 3D model and basic parametric information contained in the traditional family library, but also its 3D model has a more detailed process step layering. Each process step will contain relevant working hours, costs, quality control, and safety control information. There is a logical relationship between the process steps. It also needs to include the 2D graphics and text description of the corresponding entity of the construction process, the 3D image animation and QR code of the construction process, process acceptance photos and other information.

[0038] Operation S4, repeating operations S1 to S3 to create a construction process parameterized model of any building under other construction types.

[0039] Operation S5, repeatedly performing operations S1 to S4, so as to create a parametric model of the construction process of each building in the target building under each construction type, and form a dynamic construction process family library.

[0040] It can be understood that in this embodiment, operations S1-S3 can be repeatedly performed in operation S4 to create a parametric model of the construction process of each building in the target building under the first construction type; and operations S1-S4 can be repeatedly performed in operation S5 to create a parametric model of the construction process of each building in the target building under other construction types.

[0041] According to an embodiment of the present invention, after executing operation S5, it further includes: performing N-level classification on the dynamic construction process family library, where N≥2. The first-level classification divides the dynamic construction process family library into a building construction dynamic construction process family library, a building repair dynamic construction process family library, and a building demolition dynamic construction process family library; the Nth-level classification divides the dynamic construction process family library into various buildings and corresponding construction process parameterized models.

[0042] Preferably, N≥3, and the second-level classification divides the first-level classification into foundation and base, main structure, building decoration and decoration, building roof, building water supply and drainage and heating, building electrical, intelligent building, ventilation and air conditioning, elevator, building energy conservation and other classifications.

[0043] See also Figure 2, showing a dynamic construction process family library with four-level classification. The dynamic construction process family library includes three first-level classifications: building construction process family library, building renovation and expansion (repair) construction process family library, and building demolition construction process family library. According to the classification of the sub-projects of general industrial and civil construction projects, the first-level classification is further subdivided into eleven second-level classifications, including foundation and foundation, main structure, building decoration and renovation, building roof, building water supply and drainage and heating, building electrical, intelligent building, ventilation and air conditioning, elevator, building energy saving and others. According to the classification of sub-divisional projects, the second-level classification is subdivided into three-level classifications. Taking building decoration and renovation as an example, its basic three-level classification is divided into plastering, doors and windows, ceilings, lightweight partition walls, decorative panels (bricks), curtain walls, coatings, and details. According to actual conditions, other three-level classifications can be added. Furthermore, according to the classification of sub-projects, the three-level classification can be subdivided into four-level classifications. Taking doors and windows as an example, it includes metal doors and windows, plastic doors and windows, special doors, and door and window glass. According to actual conditions, other four-level classifications can be added. Each of the four-level classification projects (sub-projects) will correspond to different construction processes in the three stages of building construction, renovation and expansion, and demolition, and there may be more than one. Taking plastic doors and windows as an example, its building construction process is mainly reflected in different installation processes, its building renovation and expansion (repair) construction process is mainly reflected in the repair process based on its manufacturing process according to different degrees of damage, and its building demolition construction process is mainly reflected in different demolition processes adopted according to different post-demolition needs.

[0045] The creation module 410, for example, performs operation S1 to create geometric primitives of multiple construction process steps required for the construction of any building body in the target building under a first construction type, where the first construction type is building construction, building repair or building demolition.

[0046] The acquisition and addition module 420, for example, performs operation S2, which is used to filter and acquire the construction parameterization information of each construction process step and add it to the corresponding geometric primitive.

[0048] The first repeated execution module 440, for example, executes operation S4, which is used to repeatedly execute the creation module 410, the acquisition and addition module 420, and the timing setting module 430, so as to create a construction process parameterized model of any building under other construction types.

[0050] The BIM-based dynamic construction process family library construction system 400 also includes a classification module. The classification module is used to classify the dynamic construction process family library into N levels, N≥2; wherein the first level classification divides the dynamic construction process family library into a building construction dynamic construction process family library, a building repair dynamic construction process family library, and a building demolition dynamic construction process family library; the Nth level classification divides the dynamic construction process family library into various buildings and corresponding construction process parametric models.

The common Ribbon interface mode is adopted, and reasonable icons are designed, which are included in the Ribbon UI library, and the dialog box is called out using the Ribbon interface. The construction process display module mainly brings together the text introduction, video animation, step legends and other information related to the external construction process. Users can view the relevant construction process information by clicking on the dynamic construction process family library.
