Abstract
The utility model belongs to the bridge bearing technical field and discloses a ball type shock damping and insulation bearing, which is technically characterized in that: the bearing comprises an upper cover, a ball core, and a base arranged inside a box body, wherein a second friction pair consisting of a Teflon plate and a stainless steel plate is arranged on the lower part of the base, and elastic components like a bow-shaped spring steel plate in contact with the inner wall of the box body are fixed on the outer wall of the base. In case of an earthquake with intensity over 7 degree, according to the ball type shock damping and insulation bearing, the prior rigid displacement of the base can be replaced by the friction energy dissipation of the second friction pair and the flexible displacement between the elastic components like the bow-shaped spring steel plate, thereby preventing the earthquake force on the lower bearing structure from being transferred to the upper bearing structure; after the earthquake, the utility model can gradually recover. Furthermore, with a cost reduction, the utility model can greatly reduce bridge construction cost.
Description
Technical field
The utility model belongs to the bridge pad technical field, relates in particular to a kind of ball-type vibration absorption and isolation support.
Background technology
In bridge construction, need to use bridge pad tie-beam body and bridge pier, and bear vertical load.Spherical bearing is owing to having the supporting capacity height, having good performances such as multidirectional rotation and be widely used.Spherical bearing comprises cover plate, a ball core and is arranged on base in the casing, on prop up and be provided with the friction pair that polyfluortetraethylene plate and corrosion resistant plate constitute between cover plate and ball core.According to the requirement of providing fortification against earthquakes, bridge engineering generally should be able to be resisted 8 degree earthquake intensity seismic forcess.In order to reach this requirement, performance requirement to spherical bearing is very high, simultaneously the anti-seismic performance of the bridge pier of the beam body on bearing top and bearing bottom is required also very highly, the manufacturing cost of bearing is increased, more make the construction cost of whole bridge engineering increase greatly.And when earthquake, bearing can produce displacement, and the shake back is difficult for recovering, and uses after the influence.
The utility model content
Problem to be solved in the utility model just provides and a kind ofly can reduce and isolate the ball-type vibration absorption and isolation support that the substructure seismic forces can recover and can reduce greatly the bridge engineering cost after to the transmission of superstructure, shake voluntarily.
For addressing the above problem, the technical scheme that a kind of ball-type vibration absorption and isolation support of the utility model adopts is: comprise cover plate, a ball core and be arranged on the interior base of casing, go up first friction pair that is provided with polyfluortetraethylene plate and corrosion resistant plate formation between a cover plate and ball core, the bottom of described base is provided with second friction pair, and the outer wall of described base is fixed with and the contacted flexible member of cabinet wall.
Its additional technical feature is: described second friction pair is made of polyfluortetraethylene plate and corrosion resistant plate; Described flexible member is a bow type steel spring plate; Described bow type steel spring plate is four facing each other.
A kind of ball-type vibration absorption and isolation support provided by the utility model compared with prior art is provided with second friction pair in the bottom of base, is fixed with and flexible members such as the contacted bow type of cabinet wall steel spring plate at the outer wall of base.Like this, when non-earthquake or earthquake intensity≤7 were spent, bearing was equivalent to common spherical bearing, and meetings such as second friction pair of base bottom and bow type steel spring plate play the support fixation effect to base.When earthquake takes place, and earthquake intensity＞7 are when spending, and second friction pair produces relative displacement, and base compression bow type steel spring plate, and the rigid displacement of common bearing can be substituted by the flexible displacement of the distortion of friction energy-dissipating and flexible member, thereby play the effect that subtracts shock insulation.After the shake, base can set back under the effect of bow type steel spring plate gradually, thereby guarantees the result of use of bearing.And the performance requirement to spherical bearing reduced more originally, made the manufacturing cost of bearing reduce, and more made the construction cost of whole bridge engineering reduce greatly.And bow type steel spring plate is four facing each other, can make bearing can bear the horizontal seismic force of any direction, and result of use is better.
Description of drawings
Fig. 1 is the structural representation of a kind of ball-type vibration absorption and isolation support of the utility model;
Fig. 2 is the structural representation of bow type steel spring plate.
The specific embodiment
Be described in further details below in conjunction with the structure and the use principle of accompanying drawing a kind of ball-type vibration absorption and isolation support of the utility model.
As shown in Figure 1, a kind of ball-type vibration absorption and isolation support of the utility model comprises first friction pair, the ball core 4 that cover plate 1, polyfluortetraethylene plate 2 and corrosion resistant plate 3 constitute and is arranged on base 6 in the casing 5,5 of the bottom of base 6 and casings are provided with second friction pair of polyfluortetraethylene plate 7 and corrosion resistant plate 8 formations, the outer wall of base 6 is fixed with and the contacted bow type of casing 5 inwalls steel spring plate 9, and the top of casing 5 is provided with sealing plate 10.As shown in Figure 2, bow type steel spring plate 9 is fixed with the outer wall of base 6 and is contacted with the inwall of casing 5, and bow type steel spring plate 9 is four facing each other.
When the normal use of non-earthquake or earthquake intensity≤7 degree, the friction factor little (friction factor=0.03) of first friction pair that constitutes because of polyfluortetraethylene plate 2 and corrosion resistant plate 3, and the friction factor big (friction factor=0.1) of second friction pair that polyfluortetraethylene plate 7 and corrosion resistant plate 8 constitute, first friction pair that polyfluortetraethylene plate 2 and corrosion resistant plate 3 constitute is movable, and second friction pair that polyfluortetraethylene plate 7 and corrosion resistant plate 8 constitute is motionless, and the ball-type vibration absorption and isolation support is in the duty of common spherical bearing.When earthquake takes place, and when earthquake intensity＞7 are spent, horizontal seismic force is greater than the frictional force of second friction pair of polyfluortetraethylene plate 7 and corrosion resistant plate 8 formations, relative displacement takes place in polyfluortetraethylene plate 7 and corrosion resistant plate 8, base 6 compression bow type steel spring plates 9, bow type steel spring plate 9 deforms, the original rigid displacement of base 6, can be substituted by the flexible displacement of the distortion of polyfluortetraethylene plate 7 and corrosion resistant plate 8 friction energy-dissipatings and bow type steel spring plate 9, the bearing substructure no longer increases the seismic forces of bearing superstructure transmission.After the shake, base 6 can set back under the effect of bow type steel spring plate 9 gradually, thereby guarantees the result of use of bearing.
The utility model is not limited only to above-mentioned embodiment; flexible member can also be spring, rubber elastomer etc.; but no matter adopt which kind of structure, so long as, realize that the ball-type vibration absorption and isolation support that subtracts isolating affection all falls into protection domain of the present utility model in the outer wall elastic elements of base.
