ALIGNING METHOD OF STRUCTURES DURING INSTALLATION IN VERTICAL PLANE

This article presents the results of the research methods of structures aligning during installation in the vertical plane. The analysis and research of existing methods of structures alignment in the vertical plane, used in the conditions of enterprises engaged in the installation of metal tanks. The results of the research showed that the applied alignment methods in the vertical plane have some drawbacks, in particular, after aligning, additional calculations are required. And also for alignment of sliding timbering, columns and wall panels use some theodolites, including vertical allotment. Laser devices and theodolites with visual system were also investigated. However, all the methods considered with the use of these devices are quite time-consuming and a significant number of tools and equipment are used. A device is proposed to control the shape and location of flat surfaces using the principle of similarity of triangles allowing obtaining a straight line of intersection of lasers in space parallel to the plumb line. Developed devices are cheap, easy to use and manufacture. With the use of the proposed technique, there is no need to use several working and expensive devices. The developed devices can significantly reduce the alignment time of building structures in the vertical and horizontal planes.
