Vertical shock insulation support and manufacturing method thereof

Abstract

The invention discloses a vertical shock insulation support and a manufacturing method thereof and belongs to the technical field of structure shock control. The support comprises a lower supporting base provided with a groove and an upper supporting plate placed in the groove. Protruding ribs are arrayed on the periphery of the upper supporting plate. Rib grooves matched with the protruding ribs are formed in the groove wall of the groove. Damping layers are arranged on the groove walls of the rib grooves and the groove. Shock insulation layers are arranged on the groove bottoms. Large vertical bearing capacity is achieved, meanwhile, enough vertical deforming capacity and resetting capacity are achieved, vertical shock insulation effect is good, torsion shearing force in shock can be borne, torsion deforming is controlled, and the stability of the shock insulation support is improved.

Description

technical field [0001] The invention relates to the technical field of structural vibration control, in particular to a vertical shock-isolation support and a manufacturing method thereof. Background technique [0002] The seismic isolation support is an anti-seismic isolation device installed between the building or equipment and the foundation. It mainly reduces the basic frequency of structural vibration and prolongs the vibration period, thereby avoiding the main energy frequency band of earthquake vibration and making the upper structure and the ground Vibration isolation reduces the reaction of the superstructure and achieves the purpose of protecting the main structure and its internal facilities from damage. [0003] Because the influence of vertical vibration on structures cannot be ignored in earthquakes, especially high-rise structures or long-span structures, etc., are prone to resonance and damage during earthquakes. The existing seismic isolation bearings are ...

AI Technical Summary

Problems solved by technology

The existing seismic isolation bearings are mainly laminated rubber seismic isolation bearings composed of rubber and thin steel plates alternately laminated, mainly for horizontal vibration isolation, and the isolation effect on vertical vibration is not good, which is very unfavorable to structural safety. Moreover, when subjected to an earthquake, it is difficult to overcome the torsional shear moment generated

Others use multi-dimensional shock-isolation bearings, but their structures and manufacturing processes are complex and costly, which is not conducive to popularization and application
