Compound rubber ball shock absorption support for bridge

Abstract

The invention relates to a compound rubber ball shock absorption support for a bridge. The compound rubber ball shock absorption support for the bridge is composed of an internal compound rubber ball, a high-strength rope net and an external rubber ball shell, wherein the internal compound rubber ball is wrapped by the high-strength rope net which has the isotropy constraint ability, the internal compound rubber ball, the high-strength rope net and the external rubber ball shell are arranged in a mutually sleeved mode, and the external rubber ball shell tightly wraps the combination of the internal compound rubber ball and the high-strength rope net through rubber vulcanization. Horizontal deformation of the internal compound rubber ball after the internal compound rubber ball is pressed is effectively constrained due to the structural composition of the internal compound rubber ball and existence of the high-strength rope net for wrapping, and the vertical bearing capacity of the compound rubber ball shock absorption support is greatly improved. When the compound rubber ball shock absorption support for the bridge is normally used, the compound rubber ball shock absorption support for the bridge can play a role of a fixing support. The compound rubber ball shock absorption support for the bridge can consume acting energy produced by a small earthquake to the bridge through deformation when the small earthquake happens. The compound rubber ball shock absorption support for the bridge can slide and rotate under the action of a strong earthquake, and the requirement of earthquake force of a lower structure is effectively reduced. The compound rubber ball shock absorption support for the bridge is simple in structure, convenient to manufacture and high in performance cost ratio, and has high economic benefit and social benefit.

Description

technical field [0001] The invention belongs to the technical fields of bridge engineering and earthquake engineering, and in particular relates to a novel bridge damping support composed of composite rubber structures, in particular to a composite rubber ball bridge damping support. Background technique [0002] In recent decades, rubber shock-isolation bearings, as an important measure for bridge shock-isolation, have received more and more attention and achieved significant development. Plate rubber bearings and laminated rubber bearings have gradually been widely used, and have become the mainstream of bridge bearings at home and abroad. When plate-type rubber bearings or laminated rubber bearings encounter earthquakes or vibration shocks, the rubber layer consumes energy during deformation, provides damping, and provides resilience after deformation. However, for the traditional plate rubber bearing, because its appearance is flat, the inside of the rubber body is comp...

Problems solved by technology

However, for the traditional plate rubber bearing, because its appearance is flat, the inside of the rubber body is composed of thin rubber sheets and thin steel plates alternately, and the plane form is circular or rectangular; when it is subjected to rare earthquakes, its shear The shear deformation capacity is limited, because the support cannot roll and is sheared or loses its proper function, it cannot play the role of shock absorption and isolation
