Non-slip prestressed screw connections (designation GV) are used, for example, for lattice towers for wind energy plants. The professional design of the friction surfaces is of decisive importance in order to be able to guarantee the desired limit sliding force.
The stress of the connection results from the internal forces of the components to be connected. In the example below, a double-shear GV connection with a pretensioned screw was selected. Between the plates and the washers there are additional contact elements to allow sliding or friction effects.
