Isolated rolling type vibration damping device

Abstract

The invention discloses an isolated rolling type vibration damping device comprising a rolling part and a rolling disk part. According to the rolling part, a round table post 2, a rubber cushion 3, a pressure plate 4, a ball bearing seat 5, a steel ball 6 and a rolling ball 15 are sequentially installed in a control box 1 at the top from top to bottom and are also provided with clearances with the inner side of the control box 1 at the top. According to the rolling disk part, the rubber cushion 3, the round table post 2, a rolling disk seat 10 and a rolling disk 13 are installed in a control box 11 of a base from bottom to top and are also provided with clearances with the inner side of the control box 11 of the base. The inner shape of the upper part of the rolling disk 13 is a recessed body comprising a matching face contacting with the rolling ball 15 and an inclined straight face in smooth transition with the matching face, the periphery of the upper part of the recessed body is provided with a blocking edge 9, an annular rubber cushion 14 is installed at the inner side face of the blocking edge 9, and the middle point of the vertical lower part of the rolling ball 15 and the middle point of the inner shape of the upper part of the rolling disk 13 are installed in a butt-joint way when the isolated rolling type vibration damping device is used. According to the isolated rolling type vibration damping device, the problems that a foundation of a building and a main body structure are integrally connected, the breaking strength and the energy of seismic waves, which are transmitted to the main body structure, can not be isolated and converted and the building is easily destroyed by vibration waves can be effectively solved. The shock resistance of the building is enhanced, and the economic loss is reduced.

Description

technical field [0001] The invention relates to the field of anti-shock and shock-absorbing technology of buildings, in particular to an isolated rolling type shock-absorbing device. Background technique [0002] Since an earthquake is a natural phenomenon of violent movement of the earth's crust, the powerful shock wave energy spreads through the earth, which can cause large-scale damage to ground facilities and collapse of houses in an instant, causing heavy losses of people's lives and property. Although modern buildings increase the use of reinforced concrete materials, the overall structure and anti-seismic function of the building are greatly improved, but it cannot weaken and prevent the transmission energy and destructive force of seismic waves, especially for the extremely destructive horizontal shock waves and vortex shock waves , the time difference factor transmitted to the top of the main body of the building through the ground and the foundation of the building...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide an isolated rolling damping device, which solves the problem that the building foundation and the main structure are integrally connected, and the damage strength and energy transmitted by the seismic wave to the main structure cannot be isolated and converted, and the building is easily damaged by the seismic wave.
