Description
Technical field
The utility model relates to bridge pad, shock insulation rubber bearing is subtracted in particular to the multidirectional power consumption bridge of one, mainly be applicable to the railway of earthquake zone, highway and municipal bridge, also be applicable to the bridge under Chi-chi earthquake simultaneously, be specially adapted to the bridge having vertical seismic action to encourage in middle and high earthquake intensity district.
Background technology
Along with socioeconomic development, the expansion of China's traffic network, the ratio that bridge accounts in the line is more and more higher.Bridge construction is as the important component part of lifeline engineering, and be the position of most rapid wear when earthquake disaster occurs, the introducing subtracting seismic isolation technology can successfully solve bridge earthquake resistance problem.Scholars has carried out extensive, deep research to the damping of bridge construction, shock insulation, and has achieved a large amount of achievements in research.Achievement in research shows: be easier to realize and effectively subtract shock isolation method mainly adopting Antivibration support device for bridge construction ratio.At many bridges of the countries such as Japan, the U.S., New Zealand, vibration absorption and isolation support is all installed, and has achieved good damping and isolation effect.Current domestic and international existing bridge seismic isolation device is mainly divided into vibration absorption and isolation support and multiple damper etc., and wherein vibration absorption and isolation support mainly comprises laminated rubber bearing, lead core rubber support and friction pendulum support.Because neoprene bearing makes upper and lower part taphrogeny isolation by shear strain, and there is simple structure, processing and manufacturing is easy, steel using amount is few, the advantage such as with low cost, easy for installation, thus becomes the most frequently used a kind of shock isolating pedestal.
At present, domestic conventional rubber-like shock isolating pedestal mainly contains high-damp rubber support and lead core rubber support.High-damp rubber support is a kind of neoprene bearing adopting the structural member sulfuration such as high-damping rubber material and steel plate, possesses good damping capacity.But the neoprene bearing limitation that all ubiquity is certain, is mainly manifested in, and the horizontal shearing rigidity of neoprene bearing is low, and horizontal shear yield strength is low, power consumption hysteretic loop is not full, and Hysteresis Behavior is poor; Neoprene bearing vertical rigidity is low, is in pressured state for a long time, during vertical seismic action excitation, recovers distortion comparatively slowly, does not possess vertical energy dissipation capacity; Neoprene bearing does not possess vertical and level to self-resetting capability; Rubber and steel plate contact area little, damping capacity is not good, easily causes the layering pull out type fracture of bearing under earthquake.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of multidirectional power consumption bridge and subtracts shock insulation rubber bearing, effectively to improve bearing horizontal shearing rigidity and horizontal energy dissipation capacity, and there is certain vertical rigidity, go up in the horizontal and vertical direction and all possess stronger reset capability.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
The multidirectional power consumption bridge of one of the present utility model subtracts shock insulation rubber bearing, the rubber column comprising upper bracket steel plate, undersetting steel plate and be arranged between the two, it is characterized in that: in described rubber column, vertically interval arranges corrugated sheet steel, the plate face of corrugated sheet steel annular corrugatedly forms fold by radially spaced.
The beneficial effects of the utility model are, horizontal shearing rigidity and yield strength high, hysteretic loop is full, and can effectively dissipate seismic energy; Vertical and level all has automatic recovery ability, can realize the vertical reset after earthquake and horizontal reset; Bearing steel plate and rubber contact area increase, and improve the damping of support body; Possess Pyatyi energy-dissipating and shock-absorbing function, can effectively reduce and dissipation earthquake shock effect; It is convenient to install, overhaul and change, and operation maintenance cost is low.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to Fig. 1, the multidirectional power consumption bridge of one of the present utility model subtracts shock insulation rubber bearing, the rubber column 20 comprising upper bracket steel plate 11, undersetting steel plate 12 and be arranged between the two.In described rubber column 20, vertically interval arranges corrugated sheet steel 21.With reference to Fig. 4, the plate face of corrugated sheet steel 21 annular corrugatedly forms fold by radially spaced.
The vertical section of described corrugated sheet steel 21 is straight shape, upper convex or lower arcs of recesses, and Fig. 1, Fig. 2 and Fig. 3 show three kinds of typical set-up modes of corrugated sheet steel 21.With reference to Fig. 1, in described rubber column 20, the vertical section being positioned at the corrugated sheet steel 21 in its vertical centre is straight shape, and the vertical section of superposed each corrugated sheet steel 21 is lower arcs of recesses, and the vertical section being positioned at each corrugated sheet steel 21 of bottom presents convex.With reference to Fig. 2, in described rubber column 20, the vertical section of each corrugated sheet steel 21 presents convex.With reference to Fig. 3, in described rubber column 20, the vertical section of each corrugated sheet steel 21 is lower arcs of recesses.
Under dead load, corrugated sheet steel 21 is squeezed, and vertical force can be converted into horizontal loading, applies confined pressure effect to rubber, improves the compressive strength of rubber, increases bearing vertical rigidity, level to rigidity and yield strength.Under common earthquake, after the extruding of corrugated sheet steel 21 horizontal direction, elastic deformation occurs, distortion can recover automatically, realizes shock-absorbing function.Under rarely occurred earthquake, by rubber lateral extrusion, can there is plastic strain, can realize hysteretic energy in corrugated sheet steel 21 fold.When dead load is vertically compressed, increase the contact area of rubber and corrugated sheet steel 21, possess vertical recovery capability and vertical rigidity, can effectively in vertical power consumption, rubber has shock absorbing effect, can extend the bridge construction cycle, alleviate earthquake shock effect, no matter level to or vertical, structure reset capability is all very strong, substantially residual displacement does not occur.
With reference to Fig. 5, the central portion of described rubber column 20, corrugated sheet steel 21 has the vertical through holes 22 of passing for shearing force tenon (14); The upper end of described shearing force tenon 14 is fixedly connected with upper bracket steel plate 11, and lower end is then fixedly connected with undersetting steel plate 12.Shearing force tenon can be inserted at rubber column 20 center, bearing horizontal shearing rigidity and horizontal deformation can be increased, improve bearing energy dissipation capacity.
With reference to Fig. 1, Fig. 2 and Fig. 3, the vertical protective sleeve 13 extended also can be set outside the sidewall of rubber column 20.
A kind of multidirectional power consumption bridge of the above the utility model that just explains through diagrams subtracts some principles of shock insulation rubber bearing, be not the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore every corresponding modify of being likely utilized and equivalent, all belong to the scope of the claims that the utility model is applied for.
