Abstract:
The article contains the method of discrete scanning points in the vertical plane of the columns and roof trusses for the simultaneous determination of vertical columns, the distance between them in flight at their tip and deflection farms with one point standing and only one performer. The technique is based on the use of reflectorless electronic tachymeter and its SDh key. Experimental research of methods on the elements of building structures NNGASU educational housing using electronic tachymeter SET530R. Results of the experiments were monitored by a coordinate and photographic methods, as well as with the developed at the chair of Engineering Geodesy laser-mirroring device designed to measure inaccessible or hard to reach distances. Analysis methods of error theory position and the results of its comparison with other methods have shown that it provides the required accuracy, easy to perform, does not require the output of the observer on the crane path or lift to the towers, free from the multiple engagement of the bridge crane and can be successfully applied on practice.
