Device for the perception and dissipation of shock energy from the body falling under the influence of gravity

摘要

The invention relates to the field of construction, in particular to devices for protection, protection from damage, breakdowns of elements of building structures, and more specifically to devices for perception and dissipation of shock energy from falling under the influence of gravity of the body. The technical result is to simplify the design of the device and expand its functionality by providing a smooth perception and smooth dissipation of shock energy from the incident under the influence of gravity. The device comprises a damper, a fastener, a polymer element, air, a housing with a bottom, a wall, a hole and a cavity. New is that the fastener is made in the form of an adhesive composition. In the wall, at the edge of the hole, a support element is made, which is fixed to the bottom by means of an adhesive composition. The bottom is installed opposite the cavity and closes the hole. The wall, the supporting element, the adhesive composition and the bottom form a closed boundary of the cavity. The damper is formed by a wall, a support element, an adhesive composition, a bottom, a polymer element and air. The wall, the supporting element, the adhesive composition and the bottom are made with the possibility of mechanical destruction under the influence of shock energy. The polymer element is installed with the possibility of plastic deformation under the influence of shock energy and is in communication with the bottom and wall. Air is placed between the wall and the polymer element with the possibility of compression and exit beyond the cavity. The total volume of the wall, support element, adhesive composition and bottom is less than the volume of the polymer element. The wall, the supporting element, the adhesive composition and the bottom together have a lower degree of perception and dissipation of shock energy in comparison with a polymer element made of plastic polymer-containing composition. 3 il.
