Abstract
The utility model discloses a basin-shaped rubber support for bridges, belonging to the bridge support technical field. The utility model is characterized in that the utility model comprises an upper supporting plate, a lower supporting plate with a bottom basin, a bearing rubber plate with a steel seal ring at the bottom, an intermediate steel lining board and an stainless steel lining board, wherein a shock insolating and energy absorbing plate made of rubber material is fixed on the upper surface of the intermediate steel lining board, and a shock insolating damping block is fixed between the outer side of the radial direction of the upper supporting plate and the inner side of the bottom basin of the lower supporting plate. The utility model solves the problems of slip mark and wearing due to the sliding between the stainless steel plates as well as the problem of inability of auto-reset after shock. The utility model can be widely used in various bridges.
Description
Technical field
The utility model relates to a kind of bridge pad, relates in particular to a kind of bridge basin-type rubber support.
Background technology
Earthquake brings about great losses often for people's life and property as a kind of unescapable natural calamity, and especially to destruction of bridge, direct losses are bigger.The damage of bridge also can cause great influence to earthquake relief work, and therefore modern bridge construction requires to accomplish " not bad, the middle shake of little shake can be repaiied, no collapsing with strong earthquake " as the bridge pad of bridge and bridge pier connecting portion, to seem particularly important.At present the bridge pad that the uses surface of sliding relatively is between corrosion resistant plate and the corrosion resistant plate and contacts slip, this corrosion resistant plate that is in contact with one another exists following shortcoming: one, the wearing and tearing of corrosion resistant plate slide plane, seriously corroded, generally just produce phenomenons such as slide mark, pit through a slidingsurface, friction factor can increase greatly, can produce the effect of sliding when influencing earthquake, and must change again after the shake; Its two, can't automatically reset after the earthquake, must could realize resetting by external force.
The purpose of this utility model provides that a kind of damper is effective, can automatically reset bridge basin-type rubber support after the long service life, shake.For achieving the above object, the technical scheme that a kind of bridge basin-type rubber support of the utility model adopts is: the lower support plate that comprises upper bracket plate, band end basin, be fixed in pressure-bearing rubber tile, the middle steel liner plate that end basin bottom part has the steel sealing ring successively and be fixed in the stainless steel liner plate of upper bracket plate bottom, the steel liner plate upper surface is fixed with the isolation energy dissipation plate in the middle of described.
Additional technical feature of the present utility model is: described isolation energy dissipation plate is made by rubber-plastics material; Described rubber-plastics material is a polytetrafluoroethylene (PTFE); The diameter of described stainless steel liner plate is greater than the diameter of isolation energy dissipation plate; Between the basin inboard, the end of the radial outside of described upper bracket and lower support plate, be fixed with the vibration-insulation damping piece; Described vibration-insulation damping piece is for being surrounded on upper bracket plate bottom annulus.
A kind of bridge basin-type rubber support provided by the utility model, compared with prior art, have the following advantages: one, owing to be fixed with one deck on the middle steel liner plate in pot bearing by the rubber-plastics material isolation energy dissipation plate made of polyfluortetraethylene plate particularly, an energy part that at first makes earthquake produce cushions through it, secondly between the corrosion resistant plate on shockproof energy dissipating plate and the upper bearing plate during relative slip, can not produce slide mark, pit, and not perishable, long service life; They are two years old, owing between benzvalene form upper bracket plate radial outer side and end basin medial surface, be fixed with damper, can guarantee that the upper bracket plate is relative with end basin slides, and has guaranteed again that after earthquake external force is cancelled upper bracket plate and end basin can automatically restore to the origin-location.
The description of drawings and the specific embodiment
Be described further below in conjunction with the structure and the principle of the drawings and specific embodiments a kind of bridge basin-type rubber support provided by the utility model.
As shown be the structural representation of bridge basin-type rubber support that the utility model provides, its structure comprises upper bracket plate 1, middle steel liner plate 2, stainless steel liner plate 8, pressure-bearing rubber tile 4, steel sealing ring 5, the lower support plate 9 of being with end basin 6 and damper 7 etc.In the end of lower support plate 9 basin 6, be fixed with pressure-bearing rubber tile 4, middle steel liner plate 2 that periphery posts steel sealing ring 5 and the isolation energy dissipation plate of making as the rubber-plastics material of tetrafluoro polyethylene board etc. 3 successively, the upper bracket plate 1 that its bottom is fixed with stainless steel liner plate 8 is pressed on the isolation energy dissipation plate 3, is fixed with the damper of being made by block rubber or rubber ring 7 between the inboard of the outside of upper bracket plate 1 and lower support plate 9.This damper 7 both can be fixing with upper bracket plate 1, also can fix with the end basin inwall of lower support plate 9.
When earthquake, under the active force in the horizontal direction, relative slip takes place with stainless steel liner plate 8 in isolation energy dissipation plate 3, damper 7 is in upper bracket plate 1 and 9 crimps of lower support plate, after external force is cancelled, upper bracket plate 1 and lower support plate 9 return to original position under the promotion of damper 7, make bridge excellent.
In order to prevent that stainless steel liner plate 8 is pressed in the isolation energy dissipation plate of being made by rubber-plastics material 3, so with the diameter design of stainless steel liner plate 8 diameter greater than isolation energy dissipation plate 3.
