Description

Technical Field

[0001] The present invention relates to the technical field of building modeling, and in particular to a Revit-based prefabricated housing design method and system. Background Art

[0002] The traditional design method of prefabricated housing is based on two-dimensional CAD drawings, which have relatively weak three-dimensional functions and are not related to three-dimensional drawings, which are very low in terms of visibility and design efficiency. With the continuous in-depth application of BIM technology in my country's construction field, the design and deepening advantages of Revit software have gradually become prominent, and a prefabricated housing design method combining CAD and Revit has emerged: on the basis of two-dimensional drawing design, prefabricated components use Revit parametric modeling, which realizes the positioning and modification of components from a single view in CAD to the layout and modification of components from multiple views such as plane, elevation, section and three-dimensional views in Revit, solving the problem of the original two-dimensional and three-dimensional non-linkage, and improving the design quality to a certain extent.

[0003] However, since the entire design process is still based on CAD drawing design, including preliminary scheme design, mid-term splitting of prefabricated components and in-depth drawing, and three-dimensional modeling, and prefabricated components in Revit software are not system families, it is necessary to select appropriate family templates to create self-built families. The creation method is more complicated than non-assembled buildings. If all prefabricated components are created, it will also lead to low modeling efficiency. Therefore, the design efficiency has not been improved but greatly reduced, resulting in an increase in design cycle and labor costs. Therefore, this design method combining CAD and Revit has not been promoted even though it has many advantages.

[0004] In view of the above problems, there is an urgent need for a design method that is different from the traditional design method based on two-dimensional drawings. Instead, it is a design method that can realize the design of prefabricated residential schemes and the rapid disassembly and in-depth drawing of prefabricated components in Revit to solve the shortcomings of the existing technology. Summary of the invention

[0011] In a preferred embodiment, in step S23, the creation of dimension details of prefabricated components in all apartment model modules is completed, including: selecting any prefabricated component in the apartment model module, selecting the New Component command in the Modify / Part tab, changing the type name to the component number, selecting Create View in the Modify / Part tab, selecting the required type, and adding dimension annotation information in each view type to complete the dimension details of the prefabricated component, and completing the creation of dimension details of the prefabricated components in all apartment model modules.

[0012] In a preferred embodiment, in step S24, the creation of the dimension details of the prefabricated components in the traffic core model module is completed, including: selecting any prefabricated component in the traffic core model module, selecting the New Part command in the Modify / Part tab, changing the type name to the component number, selecting Create View in the Modify / Part tab, selecting the required type, and adding dimensioning information in each view type, completing the dimension details of the prefabricated components, and completing the creation of the dimension details of all prefabricated components in the traffic core model modules.

[0015] The present invention also provides a prefabricated housing design system based on Revit, comprising: A unit for creating a standard floor design scheme model, wherein the creation of the standard floor design scheme model includes: using Revit software to divide the scheme design into two parts: apartment model module design and traffic core model module design, taking the apartment model module and the traffic core model module as the minimum design unit model module, and forming different unit model design schemes through the combination of apartment modules, and then assembling the unit models into a standard floor model to finally form a scheme design model; A unit for creating a prefabricated apartment model module and a prefabricated traffic core model module, wherein the creation of the prefabricated apartment model module and the prefabricated traffic core model module includes: based on the created standard floor design scheme model, directly confirming and splitting the prefabricated components in the minimum design unit model module, and creating a prefabricated component size detailed drawing; Unit for generating fabricated standard floor models; and A unit used to optimize the solution and generate the final prefabricated residential building design model.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention uses a standardized and serialized design method, and uses Revit software to divide the scheme design into two parts: the design of the apartment model module and the design of the traffic core model module. Different unit model design schemes are formed through flexible and variable apartment module combinations, and then the unit models are assembled into standard layer models to finally form a scheme design model. This design innovation is to design with the minimum design unit model module (apartment model module and traffic core model module) as the starting point, to minimize repetitive work, and when adjusting, optimizing or deepening the design scheme, only the minimum unit model module can be modified or improved, and the scheme design model can be automatically updated by reloading the module. This modeling method has a clear process, simple operation, and can improve the speed of scheme generation and modification, and does not need to rely on two-dimensional CAD drawing design. The method of the present invention increases visibility, realizes multi-view linkage, and does not require repeated operations of each view during optimization and modification, thereby improving design efficiency.

[0017] 2. The present invention directly establishes an assembled model based on the scheme design model, and can directly determine and split prefabricated components in the determined minimum design unit model module. Prefabricated components and non-prefabricated components are divided by creating parts and splitting the parts. Composite panels, ALC strips, etc. with numbers are generated by creating the split parts as components, and finally the component dimension drawing can be directly generated. Different from the previous method of creating prefabricated components in a parametric family, the method of directly splitting components in the scheme design model of the present invention is simpler, more intuitive and easier to operate. The characteristic of Revit that components can be directly drawn can be used to add dimension parameters to the split prefabricated components to generate a two-dimensional component dimension drawing for later processing and deepening. Finally, the assembled house model module and the traffic core model module with the components split are saved and reloaded into the scheme design model, and the assembled model is automatically updated, which greatly improves the modeling efficiency.

[0018] 3. The present invention significantly improves the design quality. Since each element in Revit is automatically associated in each view, when a certain element is modified, the element in each view associated with it will be automatically updated, ensuring the consistency of the design. The drawings issued by Revit are of high quality, reducing the errors and troubles of manual drawing. Accurate 3D models can provide accurate information support for the construction and operation and maintenance stages.

[0019] 4. The present invention realizes the integrated management of design data. Revit provides detailed prefabricated component information, such as material, size, area, volume, etc. This information helps designers better understand the attribute characteristics of the building model and make accurate quantity and cost estimates.

[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below. The embodiments of the present invention and all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0023] Example 1 like Figures 1 to 6 As shown, the prefabricated housing design method based on Revit of the present invention comprises the following steps: Step S1, creating a standard floor design scheme model: using Revit software to divide the scheme design into two parts: apartment model module design and traffic core model module design, with apartment model module and traffic core model module as the minimum design unit model module, and forming different unit model design schemes through the combination of apartment modules, and then assembling the unit models into a standard floor model to finally form a scheme design model.

[0024] Specifically, in step S1, a standard layer design solution model is created, including: Step S11, creating an apartment model module: using the new project method in Revit software to create different apartment models, each apartment model is an independent rvt file; Step S12, creating a traffic core model module: creating a traffic core model module according to the above steps; Step S13, create a new project, load and assemble the apartment model module and the traffic core model module in the form of a group, compare and select the scheme, and finally form a standard floor design scheme model: select the "Load as a group" command for the new project, select the apartment model module, and then select the "Place model group" command in the "Model group" command to load it. This step is different from the traditional model loading method. This method can simultaneously realize the two operations of updating when reloading and directly editing in place. In addition, when multiple apartment model groups have been loaded, select the apartment model group instance you want to replace, and you can realize the in-situ replacement of any loaded apartment model group in the type selector drop-down list. This is very beneficial for model creation in the scheme stage, which is impossible to achieve in the traditional method. Load the traffic core model module in the same way. Since there are many different types of apartment layouts for the same area requirement, different schemes can be formed by combining the traffic core model module with different apartment model modules, and compare and select to form the final design scheme. The method of the present invention can demonstrate the assembly effect after replacement on site, which improves the speed of scheme confirmation. Finally, the apartment model group and traffic core model group in the project are converted into links, replacing and deleting the original model groups. The standard floor design model is now created.

[0025] Step S2, create prefabricated apartment model module and prefabricated traffic core model module: based on the created standard floor design scheme model, directly confirm and split the prefabricated components in the minimum design unit model module, divide the prefabricated components and non-prefabricated components by creating parts and splitting the parts, and generate numbered composite panels, ALC strips, etc. by creating the split parts as components, and finally directly generate component dimension drawings. Different from the previous method of creating prefabricated components in a parametric family, this method of directly splitting components in the scheme design model is simpler, more intuitive and easier to operate. Then, by using the feature of Revit that components can be directly drawn, the split prefabricated components can be added with size parameters to generate two-dimensional component dimension drawings for later processing and deepening.

[0026] Specifically, in step S2, creating a prefabricated housing model module and a prefabricated traffic core model module includes: Step S21, confirm and split the prefabricated components in the apartment model module: open any apartment model module, set the part visibility to display parts in the floor plan, select the prefabricated floor to be split, select Create Part in the Modify / Floor tab, create reference planes for splitting the prefabricated floor and name them respectively, select the floor to be split after the reference plane is drawn, select Split Part in the Modify / Component tab, select the intersection reference method as Reference Plane, check the name of the reference plane created for splitting the prefabricated floor, click OK to complete the splitting of the floor, select one of the prefabricated floors that has been split, add an annotation in its property panel as a composite floor, composite air-conditioning panel or composite balcony panel, uncheck the Classify by original material option, and change the material to a prefabricated component.

[0027] Step S22, confirming and splitting the prefabricated components in the traffic core model module; the confirmation and splitting method of the prefabricated components in the traffic core model module is the same as the confirmation and splitting method of the prefabricated components in the apartment model module in step S21.

[0028] Step S23, complete the creation of dimension details of prefabricated components in all apartment model modules: select any prefabricated component in the apartment model module, select the New Component command in the Modify / Part tab, change the type name to the component number, select Create View in the Modify / Part tab, select the required type, and add dimensioning information in each view type to complete the dimension details of the prefabricated component, and complete the creation of dimension details of the prefabricated components in all apartment model modules.

[0029] Step S24, complete the creation of the size details of the prefabricated components in the traffic core model module: select any prefabricated component in the traffic core model module, select the New Component command in the Modify / Part tab, change the type name to the component number, select Create View in the Modify / Part tab, select the required type, and add dimensioning information in each view type to complete the size details of the prefabricated component, and complete the creation of the size details of all prefabricated components in the traffic core model module.

[0030] In the traditional assembled Revit model, the parametric family method is used to create each prefabricated component separately, and then the family is imported into the project to assemble them separately to form an assembled model. This method completely separates the component from the whole and lacks unity. It is also cumbersome and prone to errors in the later optimization and modification process. It often needs to be created when there are component size details, which is not suitable for the scheme design stage. The assembled component splitting method proposed in the present invention is to split directly in the model, and the splitting effect is directly reflected in the model. In the later optimization and modification process, the reference plane position can be directly adjusted in the model to achieve re-division. The prefabricated component drawing does not need to be redrawn, and linkage modification can be achieved. The component size details can be directly exported from the model, which greatly improves the modeling efficiency.

[0031] Further, as shown in Figure 6, the figure shows a schematic diagram of the disassembly of a prefabricated component of a housing model module, which specifically includes the following contents: Composite slab 1: prefabricated slab, split using the method in step S2 and coded and named according to different sizes; ALC strip 2: prefabricated interior partition wall, split using step S2 method.

[0032] Special-shaped structural column 3: Created using the family method.

[0033] Aerated concrete exterior wall 4: Created using system wall family.

[0034] Basic Wall 5: Created using the system wall family.

[0035] Step S3, generating an assembled standard floor model: reloading the assembled house model module and assembled traffic core model module completed in step S2 into the standard floor design model to generate an assembled standard floor model.

[0036] Step S4, optimize the plan and generate the final prefabricated residential building design model: when the plan changes or is adjusted, find the corresponding minimum design unit model module to modify and improve it, reload it for updating, and finally improve the axis network and other parts to assemble and generate the final prefabricated residential building design model.

[0037] Example 2 The present invention also provides a prefabricated housing design system based on Revit, comprising: A unit for creating a standard floor design scheme model, wherein the creation of the standard floor design scheme model includes: using Revit software to divide the scheme design into two parts: apartment model module design and traffic core model module design, taking the apartment model module and the traffic core model module as the minimum design unit model module, and forming different unit model design schemes through the combination of apartment modules, and then assembling the unit models into a standard floor model to finally form a scheme design model; A unit for creating a prefabricated apartment model module and a prefabricated traffic core model module, wherein the creation of the prefabricated apartment model module and the prefabricated traffic core model module includes: based on the created standard floor design scheme model, directly confirming and splitting the prefabricated components in the minimum design unit model module, and creating a prefabricated component size detailed drawing; Unit for generating fabricated standard floor models; and A unit used to optimize the solution and generate the final prefabricated residential building design model.

[0038] Furthermore, a standard layer design scheme model is created, including: Create apartment model module: Create different apartment models by creating new projects in Revit software. Each apartment model is an independent rvt file. Create a traffic core model module: Create a traffic core model module according to the above steps; Create a new project, load and assemble the apartment model module and the traffic core model module in the form of groups, compare and select the schemes, and finally form the standard floor design scheme model: select the "Load as Group" command in the new project, select the apartment model module, and select the "Place Model Group" command in the "Model Group" command to load it. This step is different from the traditional model loading method. This method can simultaneously realize the two operations of updating when reloading and direct in-situ editing. In addition, when multiple apartment model groups have been loaded, select the apartment model group instance you want to replace, and you can realize the in-situ replacement of any loaded apartment model group in the type selector drop-down list. This is very beneficial for model creation in the scheme stage, which is impossible in the traditional method. Load the traffic core model in the same way, form different schemes by combining with different apartment model modules, and compare and select to form the final design scheme. Finally, convert the apartment model group and traffic core model group in the project into links, replace and delete the original model group, and the standard floor design scheme model is created.

[0039] Furthermore, a prefabricated housing model module and a prefabricated traffic core model module are created, including: Confirm and split prefabricated components in the apartment model module: open any apartment model module, set the part visibility to display parts in the floor plan, select the prefabricated slab to be split, select Create Part in the Modify / Slab tab, create reference planes for splitting prefabricated slabs and name them respectively, select the slab to be split after the reference plane is drawn, select Split Part in the Modify / Component tab, select the intersection reference method as Reference plane, check the name of the reference plane created for splitting the prefabricated slab, click OK to complete the splitting of the slab, select one of the prefabricated slabs that has been split, add an annotation in its property panel as a composite slab, composite air-conditioning panel or composite balcony panel, uncheck the Classify by original material option, and change the material to a prefabricated component.

[0040] Confirmation and splitting of prefabricated components are performed in the traffic core model module; the confirmation and splitting method of prefabricated components in the traffic core model module is the same as the confirmation and splitting method of prefabricated components in the apartment model module in step S21.

[0041] Complete the creation of dimension details of prefabricated components in all apartment model modules: select any prefabricated component in the apartment model module, select the New Part command in the Modify / Part tab, change the type name to the component number, select Create View in the Modify / Part tab, select the required type, and add dimensioning information in each view type to complete the dimension details of the prefabricated component, and complete the creation of dimension details of prefabricated components in all apartment model modules.

[0043] Furthermore, generating a prefabricated standard floor model includes: reloading the completed apartment module model and traffic core module model in the standard floor design scheme model to generate the prefabricated standard floor model.

[0044] Furthermore, the scheme is optimized to generate the final prefabricated residential building design model, including: when the scheme changes or is adjusted, the corresponding minimum design unit model module is found to be modified and improved, and it is reloaded for updating, and finally the axis network and other parts are improved to assemble and generate the final prefabricated residential building design model.
