With reference to fig. 1 to 10, a construction method of a cylindrical hyperbolic mirror support system is further described, which specifically includes the following steps:
firstly, measuring and setting out according to a design drawing of a supporting system; performing on-site inspection, scanning the site by using a 3D scanner to obtain on-site measuring point cloud data, importing the processed point cloud data into BIM related software to perform reverse modeling to obtain a civil engineering model consistent with the site, performing collision detection with the originally designed BIM model, and determining whether the construction quality of the main body structure meets the construction requirement; and making a rectification requirement on the pipeline which does not meet the requirement.
Secondly, according to the effect diagram and the design drawing, three-dimensional local refining modeling is carried out on the hyperbolic mirror panel 2, the top panel 3 and the tree column frame body 1, the sizes need to be considered comprehensively, the on-site measurement sizes are fused, and the local refining modeling is used as an original basis for processing and later-stage installation; optimizing and determining the most suitable processing sizes of the hyperbolic mirror panel 2, the top panel 3 and the unit panel of the tree column frame body 1.
Step three, after the construction work of the refinement model is finished, entering a production processing link; the refined model result is fed back to a manufacturer, and the manufacturer technicians participating in the modeling process are responsible for returning to the end of production and processing workers; decomposing the model by combining the past production and processing experience, and numbering each decomposed unit;
fourthly, deepening the three-dimensional refined model, wherein the deepening process is realized by a special computer, software adopted by the project is Rhino, and design software analyzes and simulates each plate, each column bone and the installation structure node to determine a processing and manufacturing method; during simulation, the simulation units are classified and partitioned, and the simulation mode of the plate is a twisting effect formed by adopting a single-curve plate processing mode; specifically, different positions of each plate are placed on a single-curve mold to form position differences of four angular points, then an actual three-dimensional model is used for comparison, and processing is carried out when the errors meet the design requirements, and a cutting processing diagram is derived;
if the deviation range in the fourth step can not meet the design requirement, adjusting according to the deviation value to meet the design requirement; if the difference between the positions of the four angular points of the plate and the positions of the four simulated angular points and the middle two points is within +/-3 mm, processing by adopting a single-bent-plate processing mode; if the diameter is larger than +/-3 mm, processing by adopting a processing form of a double-curved plate; in addition, as the plates are twisted, four sides are arc sides generated during lofting and unfolding, the arc sides are the same for the plates at different installation positions, and lofting and unfolding are carried out through special Rhino design software to form a planar cutting processing drawing.
