Description

[0002] In the process of compiling special construction plans for tall formwork, the selection of beam control parameters is crucial. By analyzing the beam control parameters, the main design requirements of the support system can be clarified, and a basis for construction safety and cost optimization can be provided. However, in traditional design methods, the screening and calculation of control parameters often rely on manual operations. This process is not only inefficient, but also due to the lack of precise calculation parameters and standardized processes, the accuracy and reliability of the design results are limited. Specifically, the deficiencies of the existing technology are mainly manifested in the following aspects: First, in traditional methods, key control parameters such as overweight status, wind load, and support height are mostly manually judged or calculated, lacking automated processing capabilities, resulting in a time-consuming and error-prone design process. Second, in the existing design process, the screening and classification rules for beam control parameters are vague, resulting in poor consistency and reusability of the design scheme. Third, under the changing construction environment, there is a lack of an efficient and accurate method for calculating the maximum height of beam supports under different working conditions.

[0003] Therefore, it is urgent to provide a solution to improve the above problems. Summary of the invention
