Novel replaceable energy dissipation and shock absorption composite support

Abstract

The invention relates to a novel replaceable energy dissipation and shock absorption composite support. The support comprises an upper connecting plate, a lower connecting plate, a laminated rubber elastic body, a disc spring combined element and a soft steel energy dissipation rod. The two ends of the laminated rubber elastomer are connected with the upper connecting plate and the lower connecting plate respectively, and a cylindrical center hole is formed in the center of the laminated rubber elastomer. The disc spring combined element is arranged in a central hole of the laminated rubber elastomer; the center of the disc spring combined element is provided with a soft steel energy consumption rod. The vertical compression resistance of the novel support is jointly borne by the laminated rubber elastic body and the disc spring combined element, and the disc spring combined element has good buffering and vibration absorbing capacity; the horizontal bearing capacity is borne by the laminated rubber elastomer; the soft steel energy dissipation bars provide enough tensile capacity for the support and meanwhile play a role in dissipating earthquake energy. The support has the advantages of high tension and compression resistance, remarkable energy dissipation and shock absorption effects, high fatigue resistance and high popularization value.

Description

technical field [0001] The invention belongs to the field of building structure energy consumption and shock absorption control, in particular to a novel replaceable energy consumption shock absorption composite bearing. Background technique [0002] In recent years, vibration isolation bearings have been widely used in high-rise building structures, bridge structures and large-span space structures. It is a relatively mature vibration control measure to reduce the seismic response of the structure by setting the shock absorption and isolation device on the base of the building structure or other parts. [0003] As the most common vibration isolation bearing, laminated rubber bearings are widely used in the vibration control mechanism of structures. The support can not only bear the constant load of the building, but also has good horizontal deformation ability and damping energy dissipation ability, so it can effectively isolate the building from the horizontal action of t...

Problems solved by technology

However, the tensile capacity of the existing laminated rubber isolation bearings is relatively poor, and the earthquake itself has multi-dimensional characteristics, especially for long-span and high-rise buildings under the action of a large earthquake, there will be vertical tensile stress, so it is necessary to design reasonably The vertical stiffness of the support must not only meet the requirements of the vertical bearing capacity, but also have significant energy dissipation and shock absorption to reduce the seismic response
