[0149] The present invention enables the installation of the main and secondary keels of the double steel beam support structure built on the U-shaped top support, thus providing a stable and reliable support system for subsequent construction.

[0150] Specifically, the main keel and secondary keel for establishing the double-steel support structure on the U-shaped top support include:

[0151] Mark the main keel installation point of the U-shaped top support;

[0152] Based on the main keel installation point, the main keel of the double steel beam support structure is established on the U-shaped top support;

[0153] Analyze the fixation coefficient of the main keel;

[0154] According to the fixed coefficient, mark the secondary keel installation points of the main keel;

[0156] The main keel installation point refers to the specific location on the U-shaped top support where the main keel is installed, and the main keel refers to the main load-bearing component in the double-steel beam support structure. The fixing coefficient refers to the firmness and stability index of the connection between the main keel and the U-shaped top support. The secondary keel installation point refers to the specific location on the main keel where the secondary keel is installed, which is determined in advance based on the fixing coefficient and analysis results of the main keel. The secondary keel refers to the secondary load-bearing component in the double-steel beam support structure.

[0157] Optionally, the analysis of the fixation coefficient of the main keel can be performed by mechanical analysis to calculate the stress, strain, and displacement of the main keel under static load, in order to evaluate its fixation coefficient.

[0158] Finally, based on the aforementioned double-beam support structure, the fixed beam bottom short double uprights, the U-shaped top support, the main keel, and the secondary keel, the present invention establishes a target support system for the construction scenario, creating a stable and safe target support system that meets the needs of the construction scenario. Specifically, the target support system refers to the overall framework system formed in the construction scenario, according to design requirements and safety standards, through the reasonable arrangement and connection of components such as the double-beam support, the fixed beam bottom short double uprights, the U-shaped top support, the main keel, and the secondary keel, to support construction loads and ensure construction safety and structural stability.

[0159] Firstly, the high-strength steel conversion beam disc-lock support frame construction method significantly improves the stability and construction accuracy of the support system in the construction scenario. Through in-depth analysis of the building structure and load parameters, the established support system model precisely guides the configuration and use of high-precision equipment, ensuring the accurate installation positions of components such as uprights, horizontal bars, diagonal bars, and short double uprights at the bottom of the beam. This provides a solid foundation for construction quality. The introduction of adjustable bases and the adjustment of their preset design height, combined with the calculation of the horizontal stability coefficient, constructs a stable initial support structure, further enhancing the overall structural stability and safety. The efficient integration of the integral double steel beam constructed using M14 bolts with the initial support structure forms a powerful double steel beam support structure, effectively improving the load-bearing capacity of the support system. Furthermore, by accurately calculating the vertical and spacing deviations of the fixed short double uprights at the bottom of the beam, the established U-shaped top support further optimizes the stress distribution of the support system. The establishment of the main and secondary keels based on rotation values ​​further enables fine adjustment and optimization of the support system, ensuring the efficiency, stability, and reliability of the target support system in the construction scenario. Therefore, this invention can improve the construction stability of the project.
