Embodiment Construction
[0058] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0059] A construction method for a large-scale air duct in a steel structure grid, the method uses BIM arrangement to locate the air duct to be constructed;
[0060] Through BIM typesetting, select the ball point of the steel structure grid, and weld and fix the steel plate on the ball point;
[0061] Review the upper and lower string balls of the steel structure, measure the actual net size, and optimize the BIM drawings;
[0062] Calculate the length of the steel wire rope at each point according to the optimized BIM drawing, and carry out the blanking of the steel wire rope;
[0063] Split and number the entire air duct system according to the optimized BIM drawing, and carry out on-site processing of the air duct;
[0064] Install the air ducts according to the optimized BIM drawings.
[0065] The BIM software is used to accurately positio...
