Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of and possess higher vertical bearing capacity, satisfy normal function of use, and can under earthquake or great percussion, slide, rotate by bearing, reduce the superstructure seismic forces to the neoprene bearing of substructure influence.
For reaching above purpose, the present invention breaks original neoprene bearing mentality of designing, adopt following solution: bearing adopts whole ball-type, inner compounded rubber ball adopts composite rubber material, at the high-strength netting of inner compounded rubber ball outer wrapping, and outside the assembly of inner compounded rubber ball and high-strength netting, vulcanize formation outer layer rubber spherical shell.Wherein inner compounded rubber ball comprises inner netting frame construction, and the composite rubber material of the fibrous material that can be even admixture is also made; Parcel can adopt multiple material with high-performance netting, as high tensile steel wire, macromolecular fibre cloth etc.; Its objective is when bearing is subjected to load action, inner compounded rubber ball and high-strength netting are given full play to the tensile property of fibrous composite together, distortion in space constraint core rubber bodies, far surpass the built-in steel-sheet effect of contraction of traditional neoprene bearing, thereby can increase the axial carrying capacity of bearing greatly.
Under the normal operating condition, compounded rubber ball bridge shock mount is because the effect of superstructure load deforms, and bearing and beam body, bridge pier form obvious contact surface, and bearing has and traditional laminated rubber bearing identical functions.
Under less geological process, seismic forces is less than the frictional force of compounded rubber ball bridge shock mount and bearing pad stone, bearing generation shear strain, consumed energy, simultaneously, the girder that rubber bodies can provide restoring force to make bridge jointly can reset effectively with the geological process rear support in the mechanism of earthquake and not depart from substantially, thereby ensures the traffic capacity after the bridge shake; Under the severe earthquake action, seismic forces surpasses frictional force, and compounded rubber ball bridge shock mount rolls, thereby greatly weakens the seismic forces that superstructure is delivered to substructure, plays the effect that subtracts shock insulation.Simultaneously, because compounded rubber ball bridge shock mount has isotropic characteristics, bearing is applied widely, and can both play a role to the earthquake motion input from all directions.
Accordingly, the compounded rubber ball bridge shock mount that the present invention proposes, formed by inner compounded rubber ball, high-strength netting and outside rubber spherical shell, the high-strength netting that described inner compounded rubber ball is had the isotropism restriction ability closely wraps up, obtain the assembly of inner compounded rubber ball and high-strength netting, described assembly and outside rubber spherical shell are nested with mutually; Described outside rubber spherical shell is by vulcanizing the assembly that the inner compounded rubber ball of closely knit parcel and high-strength netting are formed.
Among the present invention, the rubber that described inner compounded rubber ball and outside rubber spherical shell use can be in natural rubber, synthetic rubber or the high-damping rubber more than one.
Among the present invention, described inner compounded rubber ball is the filled circles spheroid, can be to comprise inner netting frame construction solid sphere, and the composite rubber material of about bundle fiber that can be even admixture is maybe made solid sphere.
Among the present invention, described high-strength netting braiding forms the grid with isotropism restriction ability, and described grid is triangular mesh etc., simultaneously, closely wraps up inner compounded rubber ball.
Among the present invention, the material of described high-strength netting is high tensile steel wire, or in the high fiber strength strains any.
Among the present invention, the thickness of the radius of described inner compounded rubber ball and outside rubber spherical shell can change, and is determined on a case-by-case basis.
Among the present invention, the arrangement of described internal constraint fiber and fibrous material can be adjusted according to the design needs.
Among the present invention, the intensity of the material of high-strength netting 2, material section size, spacing, the number of turns, netting grid configuration, the number of plies and manufactured materials, modulus of elasticity etc. all can be adjusted according to the design needs.
The advantage of technical scheme provided by the invention:
1) existence that the structure of inner compounded rubber spheroid is formed and appearance is wrapped up high-strength netting has retrained the lateral deformation of rubber bodies behind pressurized effectively, has improved the vertical bearing capacity of bearing greatly.
When 2) normally using, ball bearing compressive deformation, bearing and beam body, bridge pier form obvious contact surface, can play the effect of fixed bearing.
3) friction factor of rubber and pier (beam) body is greater than the friction factor of polytetrafluoro slide plate and steel plate, and under less earthquake conditions, bearing does not roll, and slides and shear strain by bearing, can consume and shake the effect energy that bridge is produced more.
4) under the severe earthquake action, bearing can take place to slide and rotate, and effectively reduces the seismic forces demand of substructure, compares the normal stack neoprene bearing and has the more excellent isolating affection that subtracts.
5) the ball-type structure does not only have the constraint of directionality when reducing the earthquake horizontal component of horizontal direction, and can also reduce structure in vertical seismic components.
