Specific embodiment:
The present invention is further detailed With reference to embodiment, purpose is only to better understand the present invention
Particular content, the cited case is not intended to limit the range that claims of the present invention is protected.
A kind of beam string installation detection control method, this method mainly includes following operating procedure:
(1), the coordinate system of beam string steel construction preassembling is established using CAD software according to design drawing；
(2), it is pre- that the three-dimensional coordinate data of each node and construction site in tension string beam structure are extracted in preassembling coordinate system
The real space coordinate of embedded part, each node is control point in the tension string beam structure；
(3), according to the deviation adjusting for the spatial data for extracting control point three-dimensional coordinate data and construction site built-in fitting
