Abstract

The invention belongs to the technical field of building shock-isolated bearings, and discloses a three-dimensional shock-isolated bearing and a preparation method for the three-dimensional shock-isolated bearing. The three-dimensional shock-isolated bearing is mainly technically characterized by comprising a laminated rubber shock-isolated bearing body, wherein a lower connection plate is arranged below the laminated rubber shock-isolated bearing body; a basin-type shear-resistant plate and a basin-type upper connection plate are arranged on the laminated rubber shock-isolated bearing body; the lower connection plate is connected with the basin-type upper connection plate via a pull-resistant limit rod; an inner pull plate is arranged on the basin inner wall of the basin-type upper connection plate; an outer pull plate matched with the inner pull plate is arranged on the basin outer wall of the basin-type shear-resistant plate; a support guide shaft is arranged on the top surface of the basin-type shear-resistant plate; a composite spring layer composed of a disc spring and multilayer rubber sheets is sleeved on the support guide shaft; and a guide groove matched with the support guide shaft is arranged on the bottom surface of the basin-type upper connection plate. The three-dimensional shock-isolated bearing disclosed by the invention can bear either a great vertical bearing force or a large pull force, and has certain stiffness and damping force in the vertical direction and the horizontal direction.

Description

technical field [0001] The invention belongs to the technical field of building shock-isolation supports, in particular to a three-way shock-isolation support and a preparation method thereof. Background technique [0002] In earthquake areas, the isolation rubber bearings used for houses, bridges or other structures can effectively isolate the transmission of seismic energy to the upper structure when an earthquake occurs, thereby reducing the damage to buildings or bridges caused by earthquake disasters. However, the structural characteristics of this vibration-isolation rubber bearing determine that its tensile strength is very low. Therefore, the national standard GB5001-2010 "Code for Seismic Design of Buildings" has made strict regulations on the tensile stress limit of building isolation rubber bearings under the simultaneous action of horizontal and vertical earthquakes that are rare in earthquakes. This deficiency of the vibration-isolation rubber bearing also limi...
