Karpenko Y. Technological providing of the exactness of the geometrical parameters of multi-storey framework-monolithic building's constructions

The research work is devoted to the questions of the technological providing and setting of the norms of the exactness of geometrical parameters of multi-storey framework-monolithic building's constructions.From the data of executive geodesic surveys more than 6000 columns were set and their rejections submit to a law of normal distribution. It is an index of statistical homogeneity and stability of a technological process of their erection. The using casting systems, the modern methods of the geodesic providing and high-fidelity geodesic devices allow to erect constructions with high exactness, which exceed the exactness of the assembling of combined reinforced concrete constructions. The analysis of the histograms of rejections of columns from a vertical axis showed that the exactness of geometrical parameters of multi-storey framework-monolithic building's constructions did not depend on a mark, where works and their geodesic accompaniment were conducted.The application of methods of the theory of chances and operating state standards gave the possibility to get the descriptions of the exactness of geometrical parameters of vertical constructions, the analysis of which allows to do a conclusion about setting of their possible deviations from a vertical axis in limits ±15 mm.The developed methodology on the basis of multifactor mathematical model for the prognostication of specific labour intensive of erection of multi-storey framework-monolithic building's constructions allows to promote the quality of preparatory works on the stage of engineering preparation of constructing of similar objects.
