Abstract
The utility model belongs to the technical field of a bridge supporting seat and discloses a shock-absorbing/isolating basin type supporting seat. The main technical characteristics of the shock-absorbing/isolating basin type supporting seat are as follows: the basin type supporting seat comprises an upper seat plate, a rubber pressure-bearing plate and a bottom basin; the bottom part of the bottom basin is a convex sphere, a base is arranged under the bottom basin, the top part of the base is a concave sphere which is matched with the convex sphere, a Teflon sliding plate is arranged between the bottom basin and the base, and a position-limiting stop block is fixed at the matching position between the top part of the base and the bottom basin by a shearing force pin. The shock-absorbing/isolating basin type supporting seat has the characteristics that: when an earthquake takes place, the bottom basin generates displacement to cut off the shearing force pin, the position-limiting stop block sheds off, and the basin type supporting seat at the upper part carries out pendulum motion along the base at the lower part, thereby achieving the purpose of shock absorption and energy dissipation; after the earthquake is eliminated, the basin type supporting seat at the upper part can automatically restores along the base at the lower part.
Description
Technical field
The utility model belongs to the bridge pad technical field, relates in particular to a kind of shock insulation pot bearing that subtracts.
Background technology
In bridge construction, horizontal movement that produces for adaptive temperature variation etc. and corner, shock attenuation needs need erection support to carry out the horizontal force that transmits on pressure-bearing and the transfer beams.Presently used pot bearing comprises upper base plate, rubber bearing plate and end basin.This pot rubber bearing can not effectively play when earthquake takes place and subtracts function of shock insulation.
The utility model content
Problem to be solved in the utility model just provide a kind of when earthquake takes place, can effectively play subtract function of shock insulation subtract the shock insulation pot bearing.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise upper base plate, rubber bearing plate and end basin, the bottom of basin of the described end is a convex surface, is provided with base below the end basin, the concave surface of the top of base for being complementary with convex surface.
Its additional technical feature is: be provided with poly-tetrafluoro slide plate between basin of the described end and base; The top of described base and basin matching part, the end are fixed with positive stop with shear pin; Described convex surface is protruding sphere, and concave surface is a concave spherical surface.
The shock insulation pot bearing that subtracts provided by the utility model, compared with prior art, the bottom of end basin is protruding sphere, be provided with base below the end basin, the top of base is the concave spherical surface that is complementary with protruding sphere, be provided with poly-tetrafluoro slide plate between basin of the described end and base, the top of described base and basin matching part, the end are fixed with positive stop with shear pin.Under normal circumstances, the pot bearing above shear pin and positive stop guarantee does not rotate and displacement, and is identical with common pot bearing effect.When earthquake took place, end basin produced displacement shear pin is cut off, and positive stop comes off, and the top pot bearing is done pendular movement along the bottom base, thereby reaches the shock-damping energy-dissipating effect.After earthquake was eliminated, the top pot bearing automatically reset along the bottom base.
Description of drawings
Fig. 1 subtracts a kind of structural representation of shock insulation pot bearing for the utility model;
Fig. 2 is the another kind of structural representation that subtracts the shock insulation pot bearing.
The specific embodiment
Below in conjunction with accompanying drawing structure and the principle that subtracts the shock insulation pot bearing provided by the utility model is described in further details.
As shown in Figure 1, 2, the shock insulation pot bearing that subtracts provided by the utility model is a fixing pot type supporting seat, comprise upper base plate 1, rubber bearing plate 2 and end basin 3, the bottom of end basin 3 is protruding sphere, be provided with base 4 below the end basin 3, the top of base 4 is the concave spherical surface that is complementary with protruding sphere, and 4 of end basin 3 and bases are provided with poly-tetrafluoro slide plate 5, and the top of base 4 and end basin 3 matching parts are fixed with positive stop 7 with shear pin 6.The shock insulation pot bearing that subtracts provided by the utility model can be fixing pot type supporting seat as shown in Figure 1, also can be unidirectional freely movable bearing as shown in Figure 2, can certainly be multidirectional movable pot bearing.
The shock insulation pot bearing that subtracts provided by the utility model, under normal circumstances, the pot bearing above shear pin 6 and positive stop 7 guarantee does not rotate and displacement, and is identical with common pot bearing effect.When earthquake took place, end basin 3 produced displacement shear pin 6 is cut off, and positive stop 7 comes off, and the top pot bearing is done pendular movement along bottom base 4, thereby reaches the shock-damping energy-dissipating effect.After earthquake was eliminated, the top pot bearing automatically reset along bottom base 4.
Claims (4)
1, subtract the shock insulation pot bearing, comprise upper base plate, rubber bearing plate and end basin, it is characterized in that: the bottom of basin of the described end is a convex surface, is provided with base below the end basin, the concave surface of the top of base for being complementary with convex surface.
