Abstract
The utility model further improves a basin type seism resistant supporting seat. A composite type multilayer structure which can load an upper seat plate is adopted in the improved direction. The multilayer structure is formed by the method that a rectangular sliding-groove plate and a cylindrical bottom seat with a sliding guide groove rail are combined. A polyfluortetraethylene sliding plate is additionally arranged between the two layers, and then, the capacity that adapts to the longitudinal displacement is enhanced. The transversal seism resistant capacity is reserved in the structure. A new variety is added for bridge supporting seats.
Description
The utility model belongs to a kind of isolated plant in the bridge construction engineering, specifically is applied to the special carrier between bridge and the bridge pier.
Along with the develop rapidly of communication, high-quality, high performance bridge pad have become the crucial construction part of whole engineering.For bridge pad, not only to guarantee the static index after engineering completes, the dynamic indicator that also will adapt to the bridge complexity changes, as temperature Change, creep, factor such as concrete shrinkage and current is to the influence of bridge, even will adapt to the strenuous vibration that paroxysmal earthquake, typhoon or other factors cause.And this strict technical indicator guarantees, to a certain extent, depends on to have high performance bridge pad.For this reason, the inventor once designed the structure of antidetonation pot bearing, in structure, adopted seat board under rectangle upper base plate and the basin shape, and design has rubber tile bearing and bearing sealing ring between the upper and lower seat board.Upper base plate has cylindrical bottom portion, be provided with the rubber damping circle between it and the basin shape upper edge, above structure has the ability of dealing with sudden shock, has better anti, but can not adapt to variation and the complicated strained situation that big length travel is arranged.
Goal of the invention of the present utility model is above basin shape aseismatic bearing is done further improvement, when making it have better anti, has the ability of good length travel, to improve the strain capacity of bridge.
Design concept of the present utility model promptly on the basis of original benzvalene form aseismatic bearing, will be carried the single stationary structure of upper base plate and change multi-layer combined structure into.In improved structure, upper base plate is made up of a rectangle sliding slot board and the cylinder base that has rectangle guiding grooved rail, be provided with the slide plate that polytetrafluoroethylmaterial material is made between sliding slot board and the guiding grooved rail plate, friction factor is between the two reduced greatly, and the relation of the position between gathering sill and the guiding grooved rail, then decision carrying upper base plate has better length travel performance, like this, in further using, its length travel ability is promptly strengthened greatly.
Simultaneously, also design has guide and limit bar and a polytetrafluoroethylene (PTFE) draw runner between upper base plate gathering sill and guiding grooved rail, the frictional force when reducing slippage.
How further specify goal of the invention of the present utility model below in conjunction with accompanying drawing realizes.
Accompanying drawing 1 is structural representation of the present utility model.
Wherein: 1 is the carrying upper base plate, and 1A is the guiding sliding slot board on the carrying upper base plate, and 1B is the guide and limit bar, and 1C is a corrosion resistant plate; 2 are cylindrical base under the last rectangular slab of tape guide grooved rail, and 2A is the polytetrafluoroethylene (PTFE) bar; 3 is the polytetrafluoroethylene (PTFE) slide plate; 4 is the base loaded plate; 5 is corrosion resistant plate; 6 is basin shape base; 7 is the rubber tile bearing; 8 is sealing ring; 9, be the damping cushion rubber.
Can further find out by accompanying drawing, carrying upper base plate 1 after the improvement has the rectangle shape of falling a groove plate (1a), it not only can longitudinally slide by the direction that grooved rail 2 limits, also can bear because the horizontal force that factors such as earthquake produce, because of having designed rectangular top cylindrical base 2 that has the grooved rail that leads and the structure that the carrying upper base plate of the rectangle 1A of falling the groove is arranged, and the frictional force when between the two, having designed polytetrafluoroethylene (PTFE) slide plate 3 with less friction factor and guide and limit bar 1B and polytetrafluoroethylene (PTFE) bar 2A and not only having reduced length travel, have the ability of horizontal antidetonation simultaneously.Adopting composite structure promptly by additional base loaded plate 4 as for cylindric base, and design in the centre two corrosion resistant plates are arranged, is in order to adjust friction factor between its base to strengthen its shock resistance.
Frictional force in practical engineering application when reducing the length travel of this bearing can add one deck corrosion resistant plate 1C between polytetrafluoroethylene (PTFE) slide plate 3 and rectangle sliding slot board 1, this plate welding is positioned on the rectangle sliding slot board.
Comprehensive the above, this improves the shock resistance that has not only guaranteed bearing, particularly horizontal shock resistance, its length travel performance is improved greatly, this provides another strong engineering support, the necessity that has wide practical use and promote to design, the construction that needs carry out the bridge of earthquake protection.
Claims (4)
1, active type antidetonation pot rubber bearing, comprise the carrying upper base plate in its structure, seat board under the basin shape, have rubber tile bearing and bearing sealing ring up and down between the seat board, do not have the rubber damping circle between upper base plate barrel portion and the following seat board basin shape upper edge, it is characterized in that upper base plate takes the layering composite structure.
2, according to the said neoprene bearing of claim 1, it is characterized in that, upper base plate is by square sliding slot board and forming with the cylinder seat of square guiding grooved rail, be provided with four fluorine ethylene slide plates between about sliding slot board and the guiding grooved rail, laterally disposed have guide and limit bar and a tetrafluoro slip positive stop strip, leaves the gap between two.
