[0017] According to one embodiment of the present application, Figure 1 is a flow chart of a BIM-based super-high cantilever steel structure lifting construction method according to an exemplary embodiment, as Figure 1 To achieve the above-mentioned purpose, the present application provides a BIM-based super-high cantilever steel structure lifting construction method, which comprises the following steps: establishing a steel structure model and a plurality of professional BIM models matched with the steel structure model; integrating the steel structure and the plurality of professional BIM models to obtain a construction comprehensive model; simulating the lifting process of the conical component based on the construction comprehensive model; optimizing the lifting construction scheme according to the simulation results and stress analysis calculation; selecting appropriate lifting equipment according to the optimized lifting construction scheme, and performing virtual installation of the lifting equipment; performing actual installation according to the results of the virtual installation, and performing real-time monitoring on the actual installation process.

[0018] According to one embodiment of the present application, a steel structure model is established based on BIM software; During the modeling process, the material, specification, size, connector type and position information of the component are input, and the integrity of the steel structure model is verified; Based on the established steel structure three-dimensional model, a plurality of professional BIM models matched with the steel structure model are established, and the information in the models is updated in time, so that the plurality of professional BIM models are always matched with the steel structure three-dimensional model; The steel structure and the BIM models of various professions are imported into Navisworks for integration, and the spatial relationship between the steel structure and the BIM models of various professions is checked based on the collision checking function, for example, it is found through collision checking that the beam in the civil structure and the column in the steel structure exist in conflict in the spatial position, the design scheme is adjusted in time to avoid the situation that installation cannot be carried out in the construction process; The design scheme is adjusted based on the checking result.

[0019] According to one embodiment of the present application, based on the adjusted design scheme, the lifting process of the conical member is simulated in BIM, for example, it is found through simulation that, in the early stage of lifting, due to the too fast lifting speed, the steel structure appears a large deformation, which exceeds the allowable range, according to the simulation result, the lifting speed is adjusted to ensure the safety of the steel structure in the lifting process; The simulation parameters are set, including the type, number and arrangement position of the lifting equipment, the lifting speed and the lifting sequence; In the simulation process, the stress condition, deformation condition and operation state of the lifting equipment of the steel structure are monitored in real time; According to the simulation process, the lifting scheme is adjusted accordingly and the simulation result is retained; The simulation data and the stress analysis result of the lifting are compared and verified, which includes comparing the stress data of a part of the steel structure obtained through simulation with the data obtained through stress analysis calculation, if there is a certain difference between the two, the attribute information is updated, including type and state; Check whether the attribute information of simulation meets the safety threshold condition, if not, trigger the early warning information to prompt the safety hazard; Through support vector machine or decision tree algorithm, the safety state of the attribute information of simulation is predicted, and the safety state is displayed in color or symbol in the BIM model, which intuitively reflects the safety risk level; Based on the related attribute information, the related parameters of the lifting process are adjusted to meet the lifting requirements and safety conditions.

[0020] According to the simulation result and the stress analysis calculation, the construction scheme is optimized. The best lifting sequence is determined, for example, to ensure the stability of the structure in the lifting process; the reasonable lifting speed is determined to avoid affecting the construction safety and efficiency due to too fast or too slow speed; the arrangement of the lifting equipment is optimized to make the equipment fully play its role, while avoiding the mutual interference between the equipment. After multiple simulation and analysis, it is determined that ten hydraulic lifters are symmetrically arranged on both sides of the conical structure for lifting, and the lifting speed is slowed down, which can not only ensure the stability of lifting, but also meet the construction progress requirements.
