FIELD: construction.
SUBSTANCE: perforated flooring is made like a framework mesh structure with longitudinal load-bearing thread-like elements, for example cables, connected with transverse rigid parts of a specified profile, e.g. tubular, wherein one of them by their ends is attached to the front racks of the device, i.e. low-level racks, and the other is interfaced movably through free segments of the longitudinal load-bearing elements with the blocks, their parts hanging behind them, located on rear racks with a height not less than the vehicle height, i.e. with forming an inclination angle between the racks of different levels, exceeding the friction angle when the vehicle enters the parking lot. In addition, loads are suspended on the hanging ends of the free segments of the longitudinal load-bearing elements, for tensioning the framework mesh structure of the flooring to the flat initial condition, and stationary stops are installed on them to limit the deflection angle of the flooring of the framework mesh structure within the specified limits of their displacement at deformation within the limits of the friction angle under the action of the gravity force of the vehicle during its parking.
EFFECT: simplifying the device design and its compatibility with the environment, with ease of installation and ease of operation of the device during the summer and winter periods of the year.
