FIELD: equipment absorbing horizontal and vertical waves and torsional forces during earthquakes. SUBSTANCE: proposed shock-proof seismic facility has cylinder attached to lower bearing flange, piston, upper bearing flange and damping elements. Cylinder kinematically coupled to lower bearing flange with diameter greater than diameter of lower cylinder is attached to upper bearing flange. Piston carries upper and lower plugs, upper plug is placed below upper edge of piston and carries steel balls contacting upper bearing flange. Damping elements come in the form of springs positioned between lower plug of piston and lower bearing flange. Space between balls is filled with synthetic material, for example, foam polyurethane. Space between springs is filled with synthetic material, either foam polyurethane or technical petroleum jelly. EFFECT: enhanced reliability of protection of buildings and structures against seismic action with various character of propagation of waves, reduced expenses for construction of antiseismic buildings and structures and potential for use of this technical approach in construction engineering, mass construction included. 3 cl, 2 dwg |
