[0044] Specifically, according to the needs and design requirements of the construction project, a three-dimensional building information model is established using BIM software. In the established building information model, the load-bearing parts that need to be supported and the required support loads are identified through analysis and calculation. This step helps to determine the location and load-bearing capacity requirements of the supports and hangers.

[0045] S200, designing supports and hangers based on the load-bearing performance requirements of the building information model, and generating support and hanger schemes for various load-bearing parts, wherein the support and hanger schemes include a plurality of optional supports and hangers; wherein each of the supports and hangers has corresponding support and hanger parameters, and the support and hanger parameters include the shape, size, material specification, and interface type of the supports and hangers;

[0046] It should be noted that the prefabricated load-bearing support and hanger brackets are mainly composed of prefabricated foundations, column bottom adjustment sections, standard sections, column top adjustment sections, column top distribution beams and ancillary facilities. The support and hanger brackets are assembled by full bolt assembly, and the problem of turnover utilization is solved through modular design.

[0047] S300, performing a combination analysis on the support and hanger schemes of each load-bearing part to obtain a support and hanger combination that meets the support load of each load-bearing part and has a low overall cost, wherein the support and hanger combination includes support and hanger parameters corresponding to each load-bearing part;

[0048] One of the main functions of prefabricated supports and hangers is to transfer the loads borne by electromechanical equipment and associated pipelines to the building structural components, and also has the functions of controlling displacement and isolating vibrations. According to the type and size of the loads borne by the prefabricated supports and hangers, the structural verification and design of the prefabricated supports and hangers can be carried out accordingly to ensure the bearing capacity and normal use of the prefabricated supports and hangers structural system.

[0049] Specifically, the performance analysis of each support and hanger scheme is carried out, including calculation and evaluation of stress, strain, stability, fatigue life, etc. The simulation and analysis tools of BIM software are used to conduct detailed analysis and comparison of various design schemes to ensure the stability and safety of the support and hanger schemes. By using the parametric characteristics of the BIM model and adjusting the design parameters, it is ensured that each scheme can meet the load-bearing performance requirements and have good stability, and a support and hanger combination that meets the load-bearing performance requirements and has a low cost is obtained.

[0050] S400, embedding each support and hanger in the support and hanger assembly into the building information model, and exporting a material list.

[0051] After marking the optimized support and hanger combination on the corresponding load-bearing parts in the building information model, it is exported as a detailed material list to ensure that the construction team can accurately understand and implement the design plan. Using BIM software to list a detailed material list helps with accurate procurement and cost control.

[0052] The present invention generates and optimizes a variety of support and hanger schemes based on the BIM model and the load-bearing performance requirements, reduces the cost of assembled support and hanger through optimized design and standardized production; simplifies the design process and improves design efficiency by utilizing the automation and parameterization characteristics of BIM technology; reduces material costs and redundant costs through detailed support load analysis and cost optimization.

[0057] In this embodiment, the endpoints in the three-dimensional model are set as connection nodes. By identifying the connection nodes in each three-dimensional model, the load-bearing parts can be obtained. Using structural analysis software (such as ANSYS, etc.), the structure can be analyzed to determine the stress conditions and load-bearing capacity of the load-bearing parts. Different load types (such as static loads, dynamic loads, wind loads, earthquake loads, etc.) will have different effects on the load-bearing parts, and need to be analyzed according to specific circumstances. Specifically, the weight of each prefabricated part in the building information model is obtained, and the load applied to the endpoint of the corresponding three-dimensional model is determined based on the weight of the prefabricated part. The load includes gravity, pressure, torsion, etc.

[0058] S130, determining the safety factor of each load-bearing part, and taking the product of the safety factor and the reference load as the required load.

[0059] After a detailed structural analysis, a safety factor is introduced according to the laboratory's design requirements and relevant specifications to consider the influence of factors such as material, manufacturing and installation errors, so as to ensure the safety performance of the support and hanger in actual use.

[0060] Through the above embodiments, the load-bearing parts and required loads of the building information model can be identified to ensure its stability and safety. At the same time, the efficiency and accuracy of the design can be improved to reduce later modifications and rework.

[0066] In this embodiment, the force simulation results include load, structural strength, displacement and vibration control. Through the force simulation, it is helpful to evaluate the performance of the support and hanger under different load conditions.

[0067] S240, for each load-bearing part, screen out the supports and hangers whose load-bearing levels meet the required load of the load-bearing part, incorporate them into the support and hanger scheme of the load-bearing part, and obtain the support and hanger schemes for each load-bearing part.

[0068] In this embodiment, available supports and hangers for each load-bearing part are screened out based on the required load to form a support and hanger solution.

[0069] As an improvement of the above embodiment, in S230, the support and hanger adapted for each prefabricated component is subjected to finite element analysis based on the parameter model, a force simulation result obtained by the finite element analysis is obtained, and the bearing level of each support and hanger is determined according to the force simulation result, including:

[0073] Specifically, according to the actual project, the loads borne by the supports and hangers are analyzed, including vertical loads, horizontal loads and torque, to determine the bearing capacity requirements of the supports and hangers. According to the load analysis results, the structural strength of the supports and hangers is calculated, including stress, strain and stability, to meet the safety and stability requirements of the project. The supports and hangers used in the laboratory have strict requirements on displacement and vibration, and the displacement and vibration of the supports and hangers need to be controlled to ensure the stability and accuracy of the experimental equipment.

[0074] As an improvement of the above embodiment, in S300, the combination analysis of the support and hanger solutions of each load-bearing part is performed to obtain a support and hanger combination that meets the support load of each load-bearing part and has a low overall cost, including:

[0075] S310, selecting a support and hanger from the support and hanger solutions of each load-bearing part to form a plurality of permutations and combinations;

[0080] It can be understood that the weight is positively correlated with the sequence number and negatively correlated with the number of support and hanger parameters. The more support and hanger parameters there are in a support and hanger category, the smaller the weight.

[0082] Specifically, for each support and hanger category, the calculated variance reflects the degree of deviation between the simulated load and the required load of each load-bearing part. Since each support and hanger in the support and hanger category meets the required load, the obtained simulated load is naturally greater than the required load. Therefore, the smaller the variance, the smaller the overall simulated load, and the lower the material cost while meeting the required load.

[0083] S360, obtain the scores of each support and hanger category, and use the support and hanger category with the highest score as the support and hanger combination.
