Abstract
The utility model discloses an anti-seismic rubber supporting base, comprising an upper base plate, a lower base plate, and a rubber plate disposed between the upper base plate and the lower base plate. The lower surface of the rubber plate is an arc-shaped surface; a Teflon plate is disposed between the rubber plate and the lower base plate; the Teflon plate is provided with an arc-shaped groove matched with the arc-shaped surface of the rubber plate; the upper surface of the upper base plate is provided with an anti-seismic base plate; a U-shaped base plate is disposed below the lower base plate; the upper surface of the U-shaped base plate is provided with a planar sliding plate; and a damping rubber ring is disposed between two supporting feet and the lower base plate. The anti-seismic rubber supporting base has commendable anti-seismic capability, seismic isolation capability and damping capability and has the function of large turning angle.
Description
Technical field
The utility model relates to a kind of bearing, particularly a kind of Anti-seismic neoprene bearing.
Background technology
At present, general fixing pot type neoprene bearing mainly is comprised of upper base plate, rubber tile and lower seat board, and movable pot rubber bearing mainly is comprised of upper base plate, rubber tile, plane tetrafluoro slide plate, middle steel plate and lower seat board, they mainly are to resist seismic forces by the structural strength that improves self, also must improve simultaneously the intensity of the bridge up-down structure that links to each other with bearing, construction cost is increased greatly.Though existing pot rubber bearing good damping effect exists the shortcoming that does not possess large angle turning function in use, though and Column face bearing possesses large angle turning function, because it all adopts steel work, thereby do not possess the Anti-seismic of subtracting neoprene bearing shake function.
The utility model content
The purpose of this utility model just is to provide a kind of and has antidetonation, shock insulation and damping capacity, and possesses the Anti-seismic neoprene bearing of large angle turning function.
To achieve these goals, the technical solution adopted in the utility model is such: Anti-seismic neoprene bearing of the present utility model, comprise upper base plate, lower seat board and be arranged on upper base plate and lower seat board between rubber tile, the soffit of described rubber tile is arcwall face, be provided with polyfluortetraethylene plate between rubber tile and the lower seat board, have the deep-slotted chip breaker with rubber tile arcwall face coupling on the polyfluortetraethylene plate, described upper base plate upper surface is provided with the antidetonation seat board, lower seat board below is provided with the U-shaped base plate, the U-shaped plate upper surface is provided with the plane slide plate, between two legs and the lower seat board, be provided with damped rubber ring.
As preferably, described lower seat board also is U-shaped, and described polyfluortetraethylene plate is arranged on lower seat board upper surface middle part.
As preferably, described antidetonation seat board is comprised of a level board and two blocks, and two blocks are separately positioned on the level board two ends.
Compared with prior art; the utility model has the advantage of: the utility model is owing to adopt the plane of rotation of spherical structure; thereby bearing integral body possesses large angle turning function, can adapt to the needs of Ramp bridge, presses the generation of inclined to one side phenomenon in the time of can avoiding beam; in structure, adopt rubber tile as pressure-containing member; make bearing integral body possess antidetonation, shock insulation and shock-absorbing function, when earthquake occurs, can adapt to well the telescopic displacement of bridge; the protection bridge is avoided seismic damage.

Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, Anti-seismic neoprene bearing of the present utility model, comprise upper base plate 2, lower seat board 4 and be arranged on upper base plate 2 and lower seat board 4 between rubber tile 3, the soffit of described rubber tile 3 is arcwall face, be provided with polyfluortetraethylene plate 6 between rubber tile 3 and the lower seat board 4, have the deep-slotted chip breaker with rubber tile 3 arcwall faces coupling on the polyfluortetraethylene plate 6, described upper base plate 2 upper surfaces are provided with antidetonation seat board 1, lower seat board 4 belows are provided with U-shaped base plate 7, U-shaped base plate 7 upper surfaces are provided with plane slide plate 5, between two legs and the lower seat board 4, be provided with damped rubber ring 8, described lower seat board 4 also is U-shaped, described polyfluortetraethylene plate 6 is arranged on lower seat board 4 upper surface middle part, and described antidetonation seat board 1 is comprised of a level board and two blocks, and two blocks are separately positioned on the level board two ends.
Adopt the plane of rotation of spherical structure; thereby bearing integral body possesses large angle turning function; the needs that can adapt to Ramp bridge; press the generation of inclined to one side phenomenon in the time of can avoiding beam, in structure, adopt rubber tile 3 as pressure-containing member, make bearing integral body possess antidetonation, shock insulation and shock-absorbing function; when earthquake occurs; the telescopic displacement that can adapt to well bridge, the protection bridge is avoided seismic damage.
