Description

Arc-shaped steel damping ball steel support
Technical field
The utility model belongs to civil engineering, earthquake engineering technical field, is specifically related to a kind of arc-shaped steel damping ball steel support.
Background technology
In recent decades, vibration absorption and isolation support subtracts the important measures of shock insulation as bridge, obtains increasing attention, and achieves great development.Pot rubber bearing, ball steel support, lead core rubber support, FPS(friction pendulum hammer body system) be progressively widely used, and become the main flow of domestic and abroad bridge bearing.In above several conventional seat, common pot rubber bearing and ball steel support are when meeting with earthquake or great vibratility is impacted, and the horizontal movement between upper and lower seat board can not get effective constraint, therefore produces excessive relative displacement, and easily fall beam harm; Lead core rubber support energy dissipation capacity is strong, the bearing second inner force that temperature, the deformation of creep such as to creep cause is less, but the cutting performance of bearing is comparatively large by the impact of vertical load, and along with the increase of lead for retractable pencil, bearing recovery capability weakens, and effectively can not subtract shock insulation in the earthquake motion with multiple spectra effect; FPS(friction pendulum hammer body system) strong, the friction energy-dissipating stable performance of automatic recovery ability, but the vertical displacement of beam-ends can be caused and produce second inner force in the process of friction energy-dissipating.
In view of all deficiencies that above-mentioned dissimilar bearing exists, we are on the basis of ball steel support, devise a kind of arc-shaped steel damping ball steel support.Common ball steel support belongs to the one of friction class bearing, it is reliable that it has power transmission, rotate flexibly, supporting capacity is large and allow the features such as displacement is large, effectively can adapt to the particular/special requirement of Longspan Bridge to bearing, but ball steel support is under geological process, on the one hand because friction factor is less, do not reach the object of effective dissipation seismic energy; On the other hand because common ball steel support does not have effective spacing measure, easily fall beam accident under geological process, therefore need further improve ball steel support.
Summary of the invention
The purpose of this utility model is to provide a kind of bearing that effectively can increase damping, reduction slide displacement and limit beam, i.e. arc-shaped steel damping ball steel support.
For reaching above object, the solution that the utility model adopts is: on the basis of common ball steel support, set up Cuvved Steel-strip energy absorber, to realize increasing damping and spacing dual purpose.
Accordingly, the utility model proposes arc-shaped steel damping ball steel support, comprise arc-shaped steel lath 5, securing cover plate 3, cover plate bolt 4 and ball steel support, described ball steel support comprises the lower seat board 2 with a chamber 9, upper base plate 1 and the sphere polyfluortetraethylene plate 8 be stacked and placed on successively from bottom to top between a chamber 9 and upper base plate 1, spherical crown 6 and plane polyfluortetraethylene plate 7, it is characterized in that: arc-shaped steel lath 5 is by semi-circular segments, horizontal segment and end composition, the two ends of semi-circular segments are respectively horizontal segment, horizontal segment connecting end portion, a groove is respectively had above longitudinal both sides of lower seat board 2, accordingly, longitudinal down either side of upper base plate 1 respectively has a groove, the shape of described groove is consistent with arc-shaped steel lath 5 end shape, the end at arc-shaped steel lath 5 two ends embeds in the groove that upper base plate 1 and lower seat board 2 have respectively, adopt securing cover plate 3 and by cover plate bolt 4, arc-shaped steel lath 5 be reliably connected with upper base plate 1 and lower seat board 2.
In the utility model, with arc-shaped steel lath 5 with the use of ball steel support be any one in bi-directional movable type, one-way movable type or fixed.
In the utility model, the arc-shaped steel lath 5 being arranged on ball steel support both sides uses single wider arc-shaped steel lath, or needs according to designing and calculating the arc-shaped steel lath using many arrangements.
The advantage of the technical scheme that the utility model provides:
1) outside its own advantages remaining common ball steel support, there is reciprocating motion when earthquake occurs by the arc-shaped steel lath set up between upper and lower seat board and play increase Damping work seismic energy, reduce the cushioning effect of slide displacement, relative displacement between the upper and lower seat board of bearing can be limited simultaneously within a controlled scope, prevent beam.
2) arc-shaped steel lath makes final molding shape in advance according to design size, and is connected and fixed by securing cover plate between upper and lower seat board, can either ensure the precision of size like this, facilitates again the assembling of arc-shaped steel lath.
3) compare the stopping means such as block, arc-shaped steel lath constitutive relation is clear, and force path is clear and definite, determines to design displacement, the balance of realizable force and displacement by calculating, and do not bend at the bottom of protection pier destruction and shear failure.
4) arc-shaped steel lath has price advantage, and can realize easy replacing in the holder, very easy to use.
In a word, the utility model is applicable on the building of urban viaduct, road bridge, railway bridge and various large-scale suspension frame structure and so on, plays cushioning effect.
