Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and particularly to an intelligent screening method for multi-condition beam control parameters for support system design. Background Art

[0002] In the process of compiling the special construction plan for high 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 limited in the accuracy and reliability of the design results due to the lack of accurate calculation parameters and standardized processes. 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 judged or calculated manually, lacking the ability of automated processing, resulting in a time-consuming and error-prone design process. Second, in the existing design process, the screening and classification rules of beam control parameters are vague, resulting in poor consistency and reusability of the design scheme. Third, in a changing construction environment, there is a lack of an efficient and accurate method for calculating the maximum height of the beam support under different conditions.
