A stainless steel plate and a friction pair are arranged between the upper support plate and the middle spherical crown plate, wherein the stainless steel plate corresponds to the arc structure, and the friction pair is formed by a wear-resistant plate made of a macromolecule plastic material. The support only needs a fixed structure type and a movable structure type, and can meet the requirements for supporting, shifting and angle turning of a small-span bridge girder system. A plurality of support bodies can bear the force in the horizontal direction at the same time, stressing is reasonable, and the service life is prolonged.
Description
Technical field
The utility model belongs to bridge pad technical field, relates in particular to a kind of horizontal force with high damping properties and disperses pot rubber bearing.
Background technology
Bearing is arranged on the important linkage between bridge superstructure and substructure.The power of displacement, corner and all directions that adapt to beam body Yin Wendu and load and produce.Along with the extensive use of laminated rubber bearing on bridge engineering, due to reasons such as raw material quality, processing technology and constructions, in use often there is ageing of rubber cracking, plate exposure, inhomogeneous drum is protruding comes to nothing, shears and transfinite and the disease such as support position play with coming unstuck.Once occur to destroy, just need to change, affect to unimpeded the causing greatly of bridge engineering safety and traffic; While also exists the distortion inequality of bearing to cause the problem of each pier stake discontinuity equalization of bridge system.
the content of invention
The purpose of this utility model is just to provide a kind of horizontal force of each pier stake stress equalization of bridge system that makes and disperses pot rubber bearing.
Realizing the technical scheme that the utility model above-mentioned purpose proposes is:
Horizontal force disperses a pot rubber bearing, and its structure comprises upper bracket plate that can be fixing with bridge beam body, middle spherical crown plate and the benzvalene form lower support plate that can be connected and fixed with bridge pier; Wherein, described upper bracket plate bottom is arcuate structure, is provided with the corrosion resistant plate corresponding with described arcuate structure and friction pair that the wearing plate made by high molecule plastic material forms between this upper bracket plate and middle spherical crown plate.
Forming above-mentioned a kind of horizontal force disperses the additional technical feature of pot rubber bearing also to comprise:
---between described middle spherical crown plate and lower support plate, be provided with the rubber tile of high rigidity;
---the rubber tile of described high rigidity is fixed by metal o-ring and described lower support plate;
---the end face of described upper bracket plate and the bottom surface of described lower support plate are provided with rubber tile;
---1/4th to 1/2nd of end basin that the thickness of described rubber tile is lower support plate;
---the border of described upper bracket plate is provided with back-up ring;
---on described upper bracket plate back-up ring, be provided with the limiting plate being bolted.
A kind of horizontal force provided by the utility model disperses pot rubber bearing, compared with prior art has the following advantages:
One, forms friction pair by the arcuate structure designing in upper bracket plated construction with the corresponding arcwall face that is arranged on middle spherical crown plate and coordinates, and the distortion that can make each bearing effective horizontal rigidity is provided and adapt to bridge, reaches each pier stress equalization; On the above and below of upper bracket plate and lower support plate, vulcanized rubber layer has increased friction factor the bumper and absorbing shock of bearing and beam body and pier; Construction install convenience, simple in structure, durability is high;
They are two years old, when beam body is subject to lateral force because of horizontal impact load, spherical crown plate in the middle of each bearing is delivered to by upper bracket plate, upper bracket plate is provided with arcwall face and reaches design level rigidity requirement with the corresponding arcwall face cooperation of middle spherical crown plate the countertorque providing in conjunction with bottom high durometer rubber plate, and the integral body that realizes girder construction is stressed;
Its three, this neoprene bearing can be realized normal displacement and corner needs, realizes shock insulation mitigation and automatically reset function simultaneously---when earthquake occurs, bearing can produce slippage; First fixedly the bolt of limiting plate is cut off, and bearing slipping central sill is known from experience a small amount of lifting, makes kinetic energy be converted to potential energy to consume part seismic energy, the back-up ring structure of limiting plate arranged outside, the stressed safety of secondary pulse of assurance girder construction; In the design of radius of curvature, make horizontal restoring force energy overcome friction, the slippage of bearing simultaneously makes rubber tile pressurized produce very large corner, and the energy of earthquake is partly stored, and for realizing after the earthquake automatically reset function, provides certain energy.
This neoprene bearing has changed stress form and the classification of the board-like bearing of traditional axle beam support, this bearing only needs fixed and movable two kinds of structural shapes, can meet the little carrying across footpath bridge system, the requirement of displacement and corner, and realize a plurality of bearings and bear the power from horizontal direction simultaneously, make stressedly more rationally to increase the service life.
Accompanying drawing explanation
Fig. 1 is the fixed structural representation that horizontal force disperses pot rubber bearing;
Fig. 2 is the active type structural representation that above-mentioned horizontal force disperses pot rubber bearing.
The specific embodiment
A kind of horizontal force the utility model being provided below in conjunction with accompanying drawing disperses the structure of pot rubber bearing to be described in further detail:
As shown in Figure 1, 2, for a kind of horizontal force provided by the utility model disperses pot rubber bearing, the structure that forms this bearing comprises that its bottom surface that can be provided with the upper bracket plate 2 of upper rubber layer 1, middle spherical crown plate 5 with its end face that bridge beam body is fixed and can be connected and fixed with bridge pier is provided with the benzvalene form lower support plate 7 of lower rubber layer 8; Wherein, above-mentioned upper bracket plate bottom is circular arc (or sphere) structure, is provided with the friction pair forming with the corrosion resistant plate 3 of above-mentioned circular arc (or sphere) structural correspondence and the wearing plate 4 made by high molecule plastic material between this upper bracket plate 2 and middle spherical crown plate; Between above-mentioned middle spherical crown plate and lower support plate, be provided with its thickness and be the rubber tile 6 of 1/4th to 1/2nd high rigidity of the end basin of lower support plate.
Above-mentioned horizontal force disperses pot rubber bearing in use, when beam body produces displacement and corner, movement by upper bracket plate 1 is delivered to middle spherical crown plate 5 by power, now, spherical crown plate 5 and rubber tile 6 have coordinated corner, now rubber tile 6 provides certain countertorque to increase horizontal rigidity, conduct to again lower support plate 7, be passed to the most at last pier.In the transmittance process of power, because being all provided with circular arc (or sphere), fixed bearing and freely movable bearing rotate sliding friction pair, can alleviate the impact of lateral force, and can make fixed bearing and freely movable bearing lateral force resisting simultaneously, avoided conventional bearing in use, the stressed excessive situation of fixed bearing, makes bridge system bearing distribution more rationally and can after shake, automatically reset, and upper glue layer 1 and lower glue layer 8 play the effect of damping noise reduction.
In forming the structure of above-mentioned horizontal force dispersion pot rubber bearing,
---the rubber tile 6 of high rigidity is fixing with benzvalene form lower support plate 7 by metal o-ring 9, loses its function to prevent rubber tile to be extruded, and the border of upper bracket plate is provided with the back-up ring 11 that is fixed with limiting plate 10 by bolt 12 simultaneously.
