Description
Technical field
The utility model belongs to technical field of bridge, particularly relates to a kind of light rail resistance to plucking pot bearing.
Background technology
In light rail viaduct bridge construction process, for the requirement such as horizontal movement, corner that adaptive temperature change etc. produces, need bearing to the vertical force transmitting superstructure dead load, mobile load causes, horizontal force to bottom pier, thus ensure that structure is at the Free Transform under the factor effect such as sanction, variations in temperature, concrete shrinkage and creep of living, graphic to make the actual loading situation of upper and lower part structure meet the static(al) of structure.Now widely used pot bearing comprises upper base plate, middle steel plate, pressure-bearing rubber tile and lower seat board, arranges corrosion resistant plate and wearing plate or polyfluortetraethylene plate and form friction pair between upper base plate and middle steel plate.When normal use, common bearing just can meet instructions for use, but vertical uplift force can be produced when an earthquake occurs, common bearing can only bear horizontal force and pressure, any effect is not produced to vertical uplift force, when earthquake occurs, each parts of bearing may occur to depart from and lose efficacy, and cause the serious consequence producing beam or fall frame.
Utility model content
The technical problems to be solved in the utility model is just to provide a kind of repertoire both having possessed common bearing, possesses again the light rail resistance to plucking pot bearing resisting vertical uplift force.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise upper base plate, middle steel plate, pressure-bearing rubber tile and lower seat board, plane stainless steel plate, plane polyfluortetraethylene plate is provided with between upper base plate bottom surface and middle steel plate end face, the bottom of described upper base plate is provided with the trapezoidal sliding pin of evagination, the top of middle steel plate is provided with the trapezoidal groove that trapezoidal sliding pin matches with evagination, and middle steel plate and lower seat board are connected by spacing connecting bolt and reserve corner amount.
Its additional technical feature is: described upper base plate is provided with postive stop baffle;
Side direction draw runner is provided with between described upper base plate and middle steel plate.
Light rail resistance to plucking pot bearing provided by the utility model, identical with common bearing function when normal operation.When an earthquake occurs, when bearing vertical force, upper base plate starts to bear vertical uplift force, and the trapezoidal groove that upper base plate is arranged by the trapezoidal sliding pin of evagination and the middle steel plate of setting interacts, and uplift force is reached middle steel plate; Power is reached lower seat board by the spacing connecting bolt arranged with lower seat board by middle steel plate; Because being fixed by crab-bolt between lower seat board and pier, thus uplift force is delivered to pier.This kind of vibrational power flow can ensure the compact and normal use of seat structure, avoids each parts of bearing to lose efficacy because of disengaging, can ensure again the stability of beam body, avoid beam or the major accidents such as frame that fall.And upper base plate is provided with postive stop baffle, when the horizontal movement of resistance to plucking pot bearing exceeds design displacement, postive stop baffle plays position-limiting action.The side direction draw runner arranged between upper base plate and middle steel plate, reduces frictional resistance.
Light rail resistance to plucking pot bearing provided by the utility model, on the basis of common pot bearing, add the syndeton of upper base plate and middle steel plate, add spacing syndeton between middle steel plate and lower seat board, glide direction adds spacing shelves bar structure.Both possessed the repertoire of common bearing, possessed again the vertical uplift force of opposing.

Fig. 2 is the vertical structure schematic diagram of light rail resistance to plucking pot bearing structure.
Detailed description of the invention
Below in conjunction with accompanying drawing, the structure of light rail resistance to plucking pot bearing provided by the utility model and principle are described further.
As shown in Figure 1, light rail resistance to plucking pot bearing provided by the utility model comprises upper base plate 1, middle steel plate 2, pressure-bearing rubber tile 3 and lower seat board 4, side direction draw runner 5 is provided with between upper base plate 1 and middle steel plate 2, plane stainless steel plate 6, plane polyfluortetraethylene plate 7 is provided with between seat board 1 bottom surface and middle steel plate 2 end face, the bottom of upper base plate 1 is provided with the trapezoidal sliding pin 8 of evagination, the top of middle steel plate 2 is provided with the trapezoidal groove 9 that trapezoidal sliding pin 8 matches with evagination, and middle steel plate 2 and lower seat board 4 are connected by spacing connecting bolt 10 and reserve corner amount.
As shown in Figure 2, middle steel plate 2 is connected by spacing connecting bolt 10 with lower seat board 4, and upper base plate 1 is provided with postive stop baffle 11.
Light rail resistance to plucking pot bearing provided by the utility model, identical with common bearing function when normal operation.When an earthquake occurs, when bearing vertical force, upper base plate 1 starts to bear vertical uplift force, and the trapezoidal groove 9 that upper base plate 1 is arranged by the trapezoidal sliding pin 8 of the evagination of setting and middle steel plate 2 interacts, and uplift force is reached middle steel plate 2; Power is reached lower seat board 4 by the spacing connecting bolt 10 arranged with lower seat board 4 by middle steel plate 2; Because being fixed by crab-bolt between lower seat board 4 and pier, thus uplift force is delivered to pier.This kind of vibrational power flow can ensure the compact and normal use of seat structure, avoids each parts of bearing to lose efficacy because of disengaging, can ensure again the stability of beam body, avoid beam or the major accidents such as frame that fall.And upper base plate 1 is provided with postive stop baffle 11, when the horizontal movement of resistance to plucking pot bearing exceeds design displacement, postive stop baffle 11 plays position-limiting action.The side direction draw runner 5 arranged between upper base plate 1 and middle steel plate 2, reduces frictional resistance.
Light rail resistance to plucking pot bearing provided by the utility model is not limited only to said structure, but regardless of which kind of form, as long as structure is identical with the utility model, all falls into protection domain of the present utility model.
