Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a method for optimizing exterior wall building nodes and forming nodes in one step based on BIM. Background Technology

[0002] Currently, during the implementation of construction projects, issues such as project construction efficiency, cost control, and on-site construction safety should be fully considered. For architectural details in areas with limited exterior wall space, especially complex details on high-rise exterior walls, it is difficult to implement on-site using traditional methods, ultimately leading to slow construction progress, uncontrollable costs, and ineffective protection of the safety of construction workers. Summary of the Invention

[0003] This invention provides a BIM-based method for optimizing and forming exterior wall building nodes in a single step. It mainly solves the construction difficulty of building nodes in confined spaces, ensures the safety of construction personnel, improves project construction efficiency, and controls construction costs.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a method for optimizing and forming exterior wall building nodes in a single step based on BIM, comprising the following steps:

[0005] Step 1: Create the main structural model based on the two-dimensional structural diagram information;

[0006] Step 2: Based on the node annotations in the floor slab structural plan, determine the structural node numbers and detailed drawing information;

[0007] Step 3: Create a structural node model using the detailed structural node dimensions drawing;

[0008] Step 4: Create a building node model based on the building node numbers and detail drawing information of the corresponding parts of the building plan;

[0009] Step 5: Analyze the structure and construction difficulty of the building nodes, and confirm whether to optimize the construction so that the structural nodes are constructed together with the main structure in one go;

[0010] Step 6: Output the building node optimization information table.

[0011] Preferably, in step one, a main structure model is created based on the two-dimensional structure diagram information. Specifically, the main structure model is a one-story, two-story, and standard floor structure model, where the standard floor is a floor with the same floor plan and consistent division.

[0012] Preferably, in step two, the structural node number and detailed drawing information are determined based on the node annotations on the floor slab structural plan. The floor slab structural plan shows detailed information about the nodes, including the application location of the structural node, the detailed node number, and the detailed drawing of the corresponding node.

[0013] Preferably, in step three, structural node models are created by using detailed drawings of structural node dimensions, and all structural node models are accurately created based on the detailed drawings of the corresponding structural node numbers and the node application location information.

[0014] Preferably, in step four, a building node model is created based on the building node number and detailed drawing information of the corresponding part of the building plan. After the above structural node model is created, the building node information needs to be confirmed in the building plan of the corresponding part, including the application part of the building node, the detailed number of the node and the detailed drawing of the corresponding node, and finally the building node model is created.

[0015] Preferably, in step five, the main factor for determining whether to optimize a building node is: for building nodes in narrow spaces, especially complex exterior wall nodes in high-rise buildings, the building nodes in narrow spaces are ultimately optimized into structural nodes and constructed together with the main structure.

[0016] Preferably, step six specifically includes: outputting the optimized building node model in sequence, and combining the floor number, corresponding grid, structural node, and building node to summarize all important information into the exterior wall node optimization table.

[0017] The present invention has the following beneficial effects:

[0018] 1. This invention uses 3D modeling in advance to identify architectural details in narrow spaces on the exterior walls, especially complex details on high-rise exterior walls. Construction using traditional methods would be difficult and the safety of construction workers would not be effectively guaranteed. By using BIM technology, complex architectural details in narrow spaces can be optimized into structural details in advance and then constructed together with the main structure. This can effectively ensure the safety of construction workers, improve project construction efficiency, and control construction costs.

[0019] 2. This invention outputs a building node optimization information table, which specifically includes important information such as floor number, corresponding grid, structural nodes, building nodes, and optimized building node model, all of which are summarized in the exterior wall node optimization table. This makes it convenient for project personnel to quickly and in real time view the optimization information of key parts. Attached Figure Description

[0028] The present invention will now be described in detail with reference to the accompanying drawings. The present invention provides a technical solution: a method for optimizing and forming exterior wall building nodes in a single step based on BIM, referring to... Figure 1 It includes the following steps:

[0029] Step 1: Refer to Figure 2 Based on the two-dimensional structural diagram information, a main structural model is created. In this embodiment, the main structural model is created using Revit software by calling the two-dimensional structural drawings. The main structural model specifically consists of a first floor, a second floor, and a standard floor model. The standard floor is a floor with the same floor plan and consistent division.

[0030] Step 2: Based on the node annotations on the floor slab structural plan, determine the structural node 1 number and detailed drawing information; the floor slab structural plan shows detailed node information, including the application location of structural node 1, the detailed node number, and the corresponding detailed node drawing; in this embodiment, the detailed information of all structural node 1 can be clearly viewed through the structural plan layout, and finally the detailed node drawing is determined by the node number content.

[0031] Step 3: Create the model of structural node 1 using the detailed drawing of structural node 1; In this embodiment, by using the detailed drawing of structural node 1 with the corresponding number, and in combination with the application location information of structural node 1, the Revit software can accurately create the model of all structural node 1.

[0032] Step Four: Refer to Figure 3 Based on the building node 2 number and detail drawing information of the corresponding part of the building plan, the building node 2 model is created. In this embodiment, after the structural node 1 model is created, the detailed information of building node 2 needs to be confirmed in the building plan of the corresponding part, including the application part of building node 2 and the detailed node number. The node size detail drawing is determined by the building node 2 number. Finally, all models of building node 2 are created using Revit software.

[0033] Step 5: Refer to Figures 4 to 7The construction and construction difficulty of building node 2 are analyzed to determine whether it should be optimized to be constructed as structural node 1 along with the main structure. In this embodiment, the construction and construction difficulty of building node 2 are analyzed first. The main factors for determining whether to optimize building node 2 to be structural node 1 are: for building node 2 in a narrow space, especially complex exterior wall nodes with high floors, on-site construction will inevitably be difficult. In order to ensure the safety of construction workers and construction efficiency, building node 2 in a narrow space is optimized to be structural node 1 along with the main structure, which effectively avoids the above problems.

[0034] Step Six: Output the Optimization Information Table for Building Node 2. In this embodiment, the optimized building node 2 model is output sequentially, and all important information such as floor number, corresponding grid, structural node 1, and building node 2 is summarized in the exterior wall node optimization table, making it convenient for relevant personnel to quickly find the optimization information of key parts.

[0035] This invention proposes a BIM-based method for optimizing and one-time forming of exterior wall architectural nodes. First, a three-dimensional overall model is created using two-dimensional structures, architectural drawings, and detailed node dimensions. Second, the construction and difficulty of architectural node 2 are analyzed, and it is confirmed that the main factor for optimizing architectural node 2 into structural node 1 is that on-site construction of architectural node 2 in confined spaces, especially complex exterior wall nodes in high-rise buildings, is inherently difficult. To ensure the safety of construction workers and improve construction efficiency, architectural node 2 is optimized. Finally, the optimized architectural node 2 model is output sequentially, and all important information, including floor number, corresponding grid lines, structural node 1, and architectural node 2, is summarized in an exterior wall node optimization table, allowing relevant personnel to quickly find optimization information for key areas. This invention effectively solves the safety problems of high-rise exterior wall node construction while significantly improving construction efficiency and strictly controlling construction costs.

[0036] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments. It should not be construed that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art should understand that any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
