PROTECTIVE BARRIER Russian patent published in 2011 - IPC E01F13/12 

FIELD: construction.

SUBSTANCE: barrier net frame is made of separate parallel belts that consist of flexible steel cord sections, and ends of an upper belt cord are pulled into an inner cavity of a fixed support by means of a block and are fixed to a vertical shock absorber, and ends of a lower belt cord are attached to fixed stands by means of traction rods via bushing supports arranged in the inner space of stands and equipped with shock-absorbing elements, and intermediate belts made of flexible steel cord sections are fixed to each other with a shift by a step in the form of inclined crossing linear elements, forming rhombic cells of the net, besides, ends of these cord sections are fixed in nodal elements of the net in a hinged manner.

EFFECT: increased specific energy consumption and higher reliability and efficiency of facilities protection due to complex application of shock-absorbing elements that serially reduce intensity of impact action.
