Description

Technical Field

[0001] This invention belongs to the field of architectural construction design technology, and specifically relates to a construction design method and system for spherical scaffolding. Background Technology

[0002] Currently, my country's urbanization has entered a new stage, and people have higher and more sophisticated demands for urban construction and daily life. This has led to a proliferation of irregularly shaped buildings, and the construction and promotion of high-tech dome theaters has become a development trend. Because dome theaters have a shell-like spatial structure, their outer cladding is often made of metal curtain walls to form an enclosed space. Due to functional requirements, there is also a projection screen inside the outer curtain wall for projecting video images, thus forming a multi-layered curtain wall system.

[0003] During the interleaved installation of the inner and outer curtain walls, in order to ensure the high-precision installation of large-scale, multi-layer curtain walls, it is necessary to design and erect operating scaffolding. However, the traditional scaffolding erection method will collide with the spherical structure, causing rework, which will cause certain troubles for construction, waste time and effort, reduce construction efficiency, and may also affect the overall stress of the already completed spherical structure during the scaffolding erection process, and also pose certain safety hazards. Summary of the Invention

[0004] This invention provides a construction design method and system for spherical structure scaffolding, which effectively solves the problem of collision between traditional scaffolding erection and spherical structures, is suitable for spherical structure buildings, and improves the efficiency and safety of scaffolding construction.

[0016] As a preferred technical solution of the present invention, in step S3, the connecting parts of the scaffold and the spherical structure in the construction drawing need to avoid key stress points, or the number of uprights and horizontal bars should be increased near key stress points.

[0017] As a preferred technical solution of the present invention, in step S4, the service load values ​​of each upright, longitudinal horizontal bar, transverse horizontal bar and connector of the scaffold are calculated in sequence and compared with the material bearing capacity limit value. At the same time, the stability of the upright is calculated by the slenderness ratio of the upright and the wind load force. If the requirements are met, proceed to the next step. If the requirements are not met, return to step S3 to adjust the scaffold layout diagram.

[0095] Example 2

[0096] See attached document Figure 2 As shown, a spherical structure scaffolding construction design system includes an analysis module 100, a drawing module 200, and a verification module 300, which are interconnected.

[0097] The analysis module 100 is used to perform stress analysis on the spherical structure. The analysis module 100 includes a drawing transmission unit 101, a parameter input unit 102, a model generation unit 103, a first calculation unit 104, and an identification unit 105. The drawing transmission unit 101 is used to import drawing files of different formats into the analysis module 100 and export the results calculated by the analysis module 100, so as to facilitate the drawing module 200 to draw the scaffolding layout diagram. The parameter input unit 102 is used to input the type and specifications of the materials used in the spherical structure. The model generation unit 103 is used to create a three-dimensional model of the spherical structure based on the imported drawings. The first calculation unit 104 is used to calculate the stress situation at each point of the three-dimensional model. The first calculation unit 104 analyzes the stress balance of the structure based on the size, material properties, splicing position, and method of the spherical structure. The identification unit 105 is used to identify key stress points. The identification unit 105 highlights the positions of the structure with large stress and easy deformation, so that designers can focus on key stress points and avoid the arrangement of scaffolding connectors in those places.

[0098] The drawing module 200 is used for drawing and adjusting the scaffolding construction layout drawing. The drawing module 200 includes a layer management unit 201, a drawing unit 202, and a printing unit 203. The layer management unit 201 is used to set different drawing layers, including at least a reference layer, a drawing layer, and an annotation layer. The reference layer is the stress analysis drawing generated by the drawing transmission unit 101, which cannot be modified within the drawing module 200 and provides a reference for the layout design. The drawing layer and annotation layer are used for current drawing and annotation. Each layer can be turned off or hidden to facilitate drawing and modification. The drawing unit 202 is used for drawing and adding graphics. The drawing unit 202 is configured with standard patterns, which can be automatically inserted or manually drawn after setting pattern parameters. The printing unit 203 is used for exporting the generated scaffolding layout drawing. The printing unit 203 scans and archives the completed drawing and exports it as a specific format file as needed.

[0099] The verification module 300 is used to calculate the stress load of each member of the scaffold. The verification module 300 includes a formula unit 301, a statistical unit 302, a second calculation unit 303, and an alarm unit 304. The formula unit 301 has pre-stored standard calculation formulas, which are collected from national standards and industry technical specifications to ensure the accuracy of the calculations. The statistical unit 302 is used to collect the name, quantity, length, and position coordinates of each member in the scaffold layout drawing. Due to the shape characteristics of the spherical structure, the length distribution of the horizontal bars connected to the spherical structure is not uniform. The information collected by the statistical unit 302 facilitates the processing and installation of the scaffold, reduces rework, and improves construction efficiency. The second calculation unit 303 is used to calculate the stress load of each member based on the formulas and statistical data. The second calculation unit 303 adopts electronic automatic calculation to reduce the error rate and save time and effort. The alarm unit 304 is used to issue an alarm signal when the calculation result of the second calculation unit exceeds the required threshold, prompting the designer to adjust the scaffold layout plan to prevent errors in the design drawings from affecting the construction progress.

[0100] This embodiment provides a spherical structure scaffolding construction design system. First, the analysis module is used to quickly model and analyze the stress situation of the spherical structure. When designing the scaffolding layout using the drawing module, the system effectively avoids the key stress points of the spherical structure, reducing the impact of scaffolding construction on the spherical structure itself. The verification module performs stress analysis and data statistics on each member of the designed scaffolding layout, making each part of the scaffolding easy to process, while ensuring that the mechanical properties of the scaffolding meet the usage requirements and ensuring construction safety.

[0101] It should be noted that the specific models and specifications of the analysis module 100, the plotting module 200, and the verification module 300 need to be selected and determined according to the actual specifications of the device.
