Abstract
The utility model relates to a rope net rubber ball bridge damping support which is composed of an inner rubber ball, a high-strength rope net and an outer rubber ball shell. The inner rubber ball is tightly wrapped by the high-strength rope net with the isotropy restraining capability. The inner rubber ball, the high-strength rope net and the outer rubber ball shell are arranged in a mutually sleeved mode. The outer rubber ball shell densely wraps the combination of the inner rubber ball and the high-strength rope net through vulcanization. The transverse deformation of the pressed inner rubber ball is effectively restrained through the high-strength rope net, and the vertical bearing capacity of the support is greatly improved. In the process of normal using, the support fixing effect can be achieved through deformation; under the weak earthquake, the action energy exerted on a bridge from the earthquake can be consumed through the deformation of the support; under the strong earthquake, the damping support can slide and rotate, so that the requirement for earthquake force of the lower structure is effectively reduced. The rope net rubber ball bridge damping support is simple in structure, convenient to manufacture and high in performance cost ratio, and has high economic benefits and social benefits.
Description
Technical field
The utility model belongs to civil engineering, earthquake engineering technical field, is specifically related to the new-type shock-absorbing bridge support of a kind of netting structure and building rubber compound, particularly a kind of netting ball shock-absorbing bridge support.
Background technology
In recent decades, shock absorption and insulation rubber support subtracts the important measures of shock insulation as bridge, obtained increasing attention, and has obtained great development.Laminated rubber bearing, pot rubber bearing etc. progressively are widely used, and become the main flow of domestic and abroad bridge bearing.In several shock absorption and insulation rubber supports, when meeting with earthquake or great vibratility and impact, rubber layer is consumed energy in deformation process, and damping is provided, and provides reset capability after shake.Yet for traditional neoprene bearing, because bearing is put more energy into, the restriction ability of steel plate is limited, and the bearing tonnage is subject to larger restriction; Simultaneously, because traditional neoprene bearing shear strain ability is poor, bearing sliding, turning power deficiency.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of and possess higher vertical bearing capacity, meet normal usage function, and can under earthquake or great percussion, pass through bearing sliding, rotation, reduce the neoprene bearing of superstructure seismic forces on the substructure impact.
For reaching above purpose, the utility model is broken original neoprene bearing mentality of designing, adopt following solution: bearing adopts whole ball-type, wrap up in high-strength netting at internal core ball overcoat, the requirement of for meeting the bearing isotropism, sliding and rolling, and strengthen the bearing durability, vulcanize outside the assembly of inner rubber ball and high-strength netting and form the outer layer rubber spherical shell.Wherein high-performance netting can adopt multiple material, as high tensile steel wire, macromolecular fibre cloth etc., its objective is when bearing is subject to load action, give full play to the tensile property of netting, the distortion of about beam core rubber, because the space constraint effect of the high-strength netting that netting ball shock-absorbing bridge support adopts to inner rubber, substantially exceed traditional neoprene bearing effect of contraction of steel plate of putting more energy into, thereby can greatly increase the axial carrying capacity of bearing.
Under normal operating condition, netting ball shock-absorbing bridge support is because the effect of superstructure load deforms, and bearing and beam body, bridge pier form obvious circular contact surface, and bearing has the function identical with traditional laminated rubber bearing.
Under than the small earthquake effect, seismic forces is less than the frictional force of netting ball shock-absorbing bridge support and bearing pad stone, bearing generation shear strain, consumed energy, simultaneously, the combination of rubber netting can provide the girder that restoring force makes bridge can effectively reset with the geological process rear support in the mechanism of earthquake and substantially not depart from jointly, thereby ensures the traffic capacity after the bridge shake; Under severe earthquake action, seismic forces surpasses frictional force, and netting ball shock-absorbing bridge support rolls, thereby greatly weakens the seismic forces that superstructure is delivered to substructure, plays the effect that subtracts shock insulation.Simultaneously, because netting ball shock-absorbing bridge support has isotropic characteristics, bearing is applied widely, and can play a role to the input of the earthquake motion from all directions.
Accordingly, the netting ball shock-absorbing bridge support the utility model proposes, be comprised of inner rubber ball, high-strength netting and outside rubber spherical shell, and the high-strength netting that described inner rubber ball is had the isotropism restriction ability closely wraps up; Assembly and outside rubber spherical shell that described inner rubber ball and high-strength netting form are nested with mutually; The assembly that described outside rubber spherical shell closely knit parcel inner rubber ball and high-strength netting form.
In the utility model, described inner rubber ball is the filled circles spheroid.
In the utility model, described high-strength netting must be woven into the grid with isotropism restriction ability (as triangle), and simultaneously, closely cover is wrapped up in the inner rubber ball.
In the utility model, described high-strength netting material is high tensile steel wire, or in high fiber strength strains any.
In the utility model, the thickness of the radius of described internal layer ball and outside rubber spherical shell can change, and is determined on a case-by-case basis.
The advantage of the technical scheme that the utility model provides:
1) existence of high-strength netting has retrained the lateral deformation of rubber bodies after pressurized effectively, has improved greatly the vertical bearing capacity of bearing.
While 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 in than the small earthquake situation, bearing does not roll, and by bearing sliding and shear strain, can consume and shake more the effect energy that bridge is produced.
4), under severe earthquake action, bearing can occur to slide and rotate, and effectively reduces the seismic forces demand of substructure, compares the normal stack neoprene bearing and has more excellent damping and isolation effect.
In a word, the utility model is applicable on the building of railway bridge, road bridge, urban viaduct and various suspension frame structures and so on, rises and subtracts function of shock insulation.
