Mounting technology from light steel structures gets ever-growing use in construction. The advantages of such technologies with their wide variety of applications are: durability, low specific gravity of structures, environmental friendliness, fire-resistance, low operation cost, fast efficient multi-season installation, resistance to stress, etc. Further development of this technology is associated with the improvement of normative base for calculation and design of buildings and related structures in light steel building constructions with indication of their loading and mounting parameters, implemented using riveting and screwed connections. Improving performance of erecting depends largely on the choice of a mechanized tool whereby these tasks are performed. Production processes of tightening screwed connections are carried out in vibroimpact modes, and one of the problems is to reduce vibration level decrease perceived by the operator, in order to protect him and extend the allowed operating hours. An effective method for solving it is employment of machinery with vibration control, with hydroimpulsive mechanisms in the drive. |
