Abstract
The utility model belongs to the technical field of bridge supporting bases, and discloses a damping tensile ball-shaped supporting base, which is mainly technically characterized in that the damping tensile ball-shaped supporting base comprises an upper seat plate, a middle lining plate, a spherical lining plate and a lower seat plate, an ultra-high molecular weight polyethylene plate is arranged between the spherical lining plate and the lower seat plate, a spherical sliding plate is arranged between the middle lining plate and the spherical lining plate, the bottom of the upper seat plate is equipped with an upper pulling plate, the upper portion of the lower seat plate is equipped with a lower pulling plate, a group of stainless steel sliding plates is arranged between the upper seat plate and the middle lining plate, a rubber damping bar is transversely arranged between the upper seat plate and the middle lining plate, and the outer side of the lower seat plate is equipped with a limit block. When having force exceeding limit instantly such as earthquake and the like, two stainless steel sliding plates on the upper portion of the damping tensile ball-shaped supporting base oppositely rub to eliminate energy after the limit block of the damping tensile ball-shaped supporting base limits displacement. The damping tensile ball-shaped supporting base is transversely equipped with the rubber damping bar which has a certain buffer function after eliminating energy.
Description
Technical field
The utility model belongs to the bridge pad technical field, relates in particular to a kind of damping tension spherical bearing.
Background technology
Needing erection support to carry out the horizontal force that transmits on pressure-bearing and the transfer beams on bridge or the rack.Bearing not only will bear pressure, horizontal force, but also will bear the pulling force of vertical direction, and requires to have certain shock resistance.Presently used ball-type mode tensile supporting seat comprises upper base plate, middle liner plate, sphere liner plate and following seat board, be provided with ultra high molecular polyethylene plate between sphere liner plate and following seat board, be provided with the sphere slide plate between middle liner plate and sphere liner plate, the bottom of upper base plate is provided with arm-tie, and the top of following seat board is provided with lower pulling plate.This spherical bearing can bear pressure, horizontal force and pulling force, but lacks buffer capacity when earthquake takes place.
The utility model content
Problem to be solved in the utility model just provides a kind of damping tension spherical bearing that has buffer capacity when earthquake takes place.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise upper base plate, middle liner plate, sphere liner plate and following seat board, be provided with ultra high molecular polyethylene plate between sphere liner plate and following seat board, be provided with the sphere slide plate between middle liner plate and sphere liner plate, the bottom of upper base plate is provided with arm-tie, the top of following seat board is provided with lower pulling plate, is provided with one group of stainless steel slide plate between described upper base plate and middle liner plate.
Its additional technical feature is: described upper base plate and middle liner plate laterally between be provided with the rubber damping bar; The described arranged outside of seat board down has limited block.
Damping tension spherical bearing provided by the utility model compared with prior art, is provided with one group of stainless steel slide plate between upper base plate and middle liner plate, upper base plate and middle liner plate laterally between be provided with the rubber damping bar, the arranged outside of following seat board has limited block.In use, normal condition since down the centre of seat board and the ultra high molecular polyethylene plate composition moving sets friction factor that adds silicone grease less than the friction factor between two stainless steel slide plates between the upper base plate on top and middle liner plate.When bridge or rack moved, the sphere liner plate at first moved and meets the demands.When the drawing phenomenon appears in bearing, the drag hook structure stress of upper and lower seat board and middle liner plate opposing pulling capacity.When moments such as earthquake occur goes beyond the limit of power, limited block with offset qualification after, the top two stainless steel slide plates elimination energy that rubs relatively.Laterally be provided with the rubber damping bar, play certain cushioning effect after the energy dissipating.
Description of drawings
Fig. 1 is the transversary schematic diagram of the utility model damping tension spherical bearing;
Fig. 2 is the vertical structure schematic diagram of damping tension spherical bearing.
The specific embodiment
Be described in further details below in conjunction with the structure and the principle of accompanying drawing damping tension spherical bearing provided by the utility model.
As shown in Figure 1, damping tension spherical bearing provided by the utility model comprises upper base plate 1, middle liner plate 2, following seat board 3, sphere liner plate 5, sphere liner plate 5 and 3 of following seat boards are provided with ultra high molecular polyethylene plate 4, middle liner plate 2 and 5 of sphere liner plates are provided with sphere slide plate 6, upper base plate 1 and middle liner plate 2 laterally between be provided with rubber damping bar 7, the bottom of upper base plate 1 is provided with arm-tie 8, the top of following seat board 3 is provided with lower pulling plate 9, and 2 of upper base plate 1 and middle liner plates are provided with one group of stainless steel slide plate 10.As shown in Figure 2, the arranged outside of following seat board 3 has limited block 11.
Damping tension spherical bearing provided by the utility model, under normal circumstances, the centre formed of following seat board 3 and the ultra high molecular polyethylene plate 4 moving sets friction factor that adds silicone grease is less than the friction factor of 10 on the upper base plate 1 on top and 2 two stainless steel slide plates of middle liner plate.When bridge or rack moved, sphere liner plate 5 at first moved and meets the demands.When the drawing phenomenon appears in bearing, the last arm-tie 8 of upper base plate 1, the lower pulling plate 9 stressed opposing pulling capacities of following seat board 3.When moments such as earthquake occur went beyond the limit of power, limited block 11 was with after the offset qualification, and top two stainless steel slide plates 10 friction are relatively eliminated energy.Laterally be provided with rubber damping bar 7, play certain cushioning effect after the energy dissipating.
Claims (3)
