Abstract
The utility model belongs to the technical field of bridge supports and discloses a pot tensile support. The main technical characteristics are that: the support comprises an upper base plate, a middle steel liner plate, a pressure-bearing rubber plate and a lower base plate; a convex lug is arranged at the top part of the lower base plate, a pull handle matched with the convex lug is arranged at the bottom part of the upper base plate. When vertical pulling force and transverse shearing force are produced in earthquake, the pot tensile support provided by the utility model can counteract the vertical pulling force and transverse shearing force on the basis of keeping the whole supporting base to be complete, and ensures that the supporting base structure is compact and can be used normally. Besides, the support can reduce beam end counterweight and resist the actions of the vertical pulling force and transverse shearing force generated by centrifugal force, earthquake force, transverse swing force, transverse wind force, seawater wave force and the like.
Description
Technical field
The utility model belongs to the bridge pad technical field, relates in particular to a kind of benzvalene form mode tensile supporting seat.
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, middle steel liner plate, pressure-bearing rubber tile and following seat board, is provided with the friction pair that stainless steel slide plate or antifriction plate and tetrafluoro slide plate constitute between upper base plate and middle steel liner plate.This pot rubber bearing in use can only bear horizontal force and pressure, can not be to the pulling force generation effect of vertical direction.The beam or the frame that falls fall when earthquake takes place.
The utility model content
Problem to be solved in the utility model just provide a kind of can be to the benzvalene form mode tensile supporting seat of the pulling force generation effect of vertical direction.
For solving the problems of the technologies described above, the technical scheme that the utility model benzvalene form mode tensile supporting seat adopts is: comprise upper base plate, middle steel liner plate, pressure-bearing rubber tile and following seat board, the described top of seat board down is provided with lug, and the bottom of upper base plate is provided with the handle that is complementary with lug.
Its additional technical feature is: described lug is square, and shaking hands to the cross section is the bar shaped of L type; The external surface of described lug is provided with closure plate, and the inner surface of handle is provided with the stainless steel slide plate; Described handle and upper base plate flexibly connect or are connected as a single entity.
Benzvalene form mode tensile supporting seat provided by the utility model, compared with prior art, the top of following seat board is provided with lug, and the bottom of upper base plate is provided with the handle that is complementary with lug.It is to carry out pressure-bearing and rotation with the pressure-bearing rubber tile, adapts to the displacement request of bridge with the friction pair of polyfluortetraethylene plate or antifriction plate and corrosion resistant plate formation.Set up the puller system that handle and lug constitute, when earthquake produces vertical pulling force and cross shear, handle offsets vertical pulling force and cross shear whole bearing to the lug effect on the basis that is kept perfectly, guarantee the compactness and normal use of seat structure.Alleviate beam-ends counterweight and effects such as the vertical pulling force of resisting generations such as centrifugal force, seismic forces, transverse rocking force, transverse wind and waves of seawater power and cross shear in addition.In addition, lug is a square, and shaking hands to the cross section is the bar shaped of L type, makes easy to assemblyly, and as required, handle can flexibly connect with upper base plate or be connected as a single entity.And the external surface of lug is provided with closure plate, and the inner surface of handle is provided with the stainless steel slide plate, makes that frictional force is little between upper base plate and following seat board.
Description of drawings
Fig. 1 is the structural representation of the utility model benzvalene form mode tensile supporting seat;
Fig. 2 is the structural representation of upper base plate;
Fig. 3 is the structural representation of following seat board.
The specific embodiment
Be described in further details below in conjunction with the structure and the principle of accompanying drawing benzvalene form mode tensile supporting seat provided by the utility model.
As shown in Figure 1, benzvalene form mode tensile supporting seat provided by the utility model comprises upper base plate 1, middle steel liner plate 2, pressure-bearing rubber tile 3 and following seat board 4, the top of following seat board 4 is provided with lug 5, the bottom of upper base plate 1 is provided with the handle 6 that is complementary with lug 5, the external surface of lug 5 is provided with closure plate 7, and the inner surface of handle 6 is provided with stainless steel slide plate 8.As shown in Figure 2, handle 6 is the bar shaped of L type for the cross section.As shown in Figure 3, lug 5 is a square, can certainly be rectangle or other polygon.
Benzvalene form mode tensile supporting seat provided by the utility model, when earthquake produces vertical pulling force and cross shear, 6 pairs of lugs 5 effect of shaking hands is offset vertical pulling force and cross shear whole bearing on the basis that is kept perfectly, guarantee the compactness and normal use of seat structure.As required, handle 6 can flexibly connect with upper base plate 4 or be connected as a single entity.And the external surface of lug 5 is provided with closure plate 7, and the inner surface of handle 6 is provided with stainless steel slide plate 8, makes that upper base plate 1 and 4 frictional force of following seat board are little.According to the different requirements of one-way support, bilateral support and fixed bearing, on fixed bearing, closure plate 7 and stainless steel slide plate 8 can be installed.
