Abstract
The utility model discloses a plate-type damping rubber support which comprises a rubber plate, a beam bottom anchorage structure and an abutment top anchorage structure. The upper end of the rubber plate is fixedly connected with an upper support plate, the upper support plate is fixedly connected with the beam bottom anchorage structure, the lower end of the rubber plate is fixedly connected with a lower support plate, and the lower support plate is fixedly connected with the abutment top anchorage structure. A central hole is formed in the upper support plate, a shearing force pin is embedded in the central hole, the upper portion of the shearing force pin enters the beam bottom anchorage structure, and the shearing force pin is fixedly connected with the beam bottom anchorage structure. The plate-type damping rubber support is simple in structure and novel in design, enables a rubber layer to be even in stress, enables vertical bearing to be reliable, enables transmission of horizontal force to be stable, is convenient to install, and has the advantages of being reliable in force transmission, flexible in rotation, big in bearing capacity, big in displacement, good in anti-seismic property and the like.
Description
Technical field
The utility model relates to the bridge pad technical field, refers to it is a kind of board-like damping rubber bearing particularly.
Background technology
At present, the bridge laminated rubber bearing that uses is to be formed by multi-layer thin steel plate and multilayer rubber sulfuration adhesion, the counter-force of superstructure can be passed to pier, can adapt to beam-ends and vertically rotate, have the horizontal shear deformability, can satisfy the horizontal movement of superstructure.But in the practice of construction process, because of reasons such as on-the-spot and construction errors, can produce installation then part not in place and come to nothing or surperficial discontinuity, easily the phenomenon of cracking; Only depend on rubber tile and concrete stiction to transmit horizontal force after being installed on the bridge, do not have anchor connection between bearing and beam body and pier, bearing produces slippage sometimes under dynamic vehicle load vibration effect, influence the vertical bearing safety of bearing; The elastomeric material deformability is not high, and bearing is out of shape bigger when bridge expands with heat and contract with cold, and (seismic forces, brake force, wind load) horizontal distortion scarce capacity is easy to cause bearing rubber to tear when superposeing other load again.
The utility model content
The purpose of this utility model is exactly the deficiency that will solve the above-mentioned background technology, provides a kind of and has the bearing capacity height, the horizontal force transmission is reliable, anti-seismic performance good, the board-like damping rubber bearing of the characteristics of long service life.
The technical solution of the utility model is: a kind of board-like damping rubber bearing, comprise anchorage structure at the bottom of rubber tile, the beam, pier top anchorage structure, it is characterized in that: the upper end of described rubber tile is fixedly connected with the upper bracket plate, the upper bracket plate is fixedlyed connected with anchorage structure at the bottom of the beam, the lower end of described rubber tile is fixedly connected with lower support plate, and lower support plate is fixedlyed connected with pier top anchorage structure; Offer centre bore in the described upper bracket plate, described centre bore is embedded with shear pin, and the top of shear pin enters into anchorage structure at the bottom of the beam, and shear pin is fixedlyed connected with anchorage structure at the bottom of the beam.
In such scheme:
Be provided with sulfur tank in the described upper bracket plate, upper bracket plate and rubber tile are bonding by sulfuration.
Be provided with sulfur tank in the described lower support plate, lower support plate and rubber tile are bonding by sulfuration.
Advantage of the present utility model is:
1, the upper end of rubber tile is fixedly connected with the upper bracket plate, and the lower end of rubber tile is fixedly connected with lower support plate, makes things convenient for bearing that the location is installed, and upper and lower seat board also can make rubber tile evenly bear vertical bearing capacity simultaneously;
2, the horizontal force of bridge superstructure is passed to bridge substructure through combination, rubber tile, the lower support plate of upper bracket plate and shear pin, its horizontal force transmission more reliable, and bearing can not produce slippage yet under dynamic vehicle load vibration effect;
3, be provided with sulfur tank in upper bracket plate, the lower support plate, rubber tile and upper bracket plate, lower support plate are passed through to vulcanize bonding, have promoted rubber tile shearing resistance adhesive property, make the horizontal force transmission more reliable of rubber tile.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
The specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments, be convenient to be well understood to the present invention, but they do not constitute restriction to the present invention.
As shown in Figure 1, a kind of board-like damping rubber bearing, it comprises rubber tile 3, is provided with steel plate in the rubber tile 3.It also comprises anchorage structure 5 at the bottom of the beam, pier top anchorage structure 6, be fixedly connected with upper bracket plate 1 in the upper end of rubber tile 3, upper bracket plate 1 is fixedlyed connected with anchorage structure 5 at the bottom of the beam, be fixedly connected with lower support plate 4 in the lower end of rubber tile 3, lower support plate 4 is fixedlyed connected with pier top anchorage structure 6, makes things convenient for bearing that the location is installed, and upper bracket plate 1 and lower support plate 4 also can make rubber tile 3 evenly bear vertical bearing capacity.
In upper bracket plate 1, offer centre bore 7, centre bore is embedded with shear pin 2, the top of shear pin 2 enters into anchorage structure 5 at the bottom of the beam, shear pin 2 is fixedlyed connected with anchorage structure 5 at the bottom of the beam, the horizontal force of bridge superstructure is passed to bridge substructure through combination, rubber tile 3, the lower support plate 4 of upper bracket plate 1 and shear pin 2 like this, its horizontal force transmission more reliable, and bearing can not produce slippage yet under dynamic vehicle load vibration effect.
Be provided with sulfur tank in the upper bracket plate 1, upper bracket plate 1 is bonding by sulfuration with rubber tile 3, also is provided with sulfur tank in the lower support plate 4, and lower support plate 4 is bonding by sulfuration with rubber tile 3, promoted rubber tile 3 shearing resistance adhesive properties, made the horizontal force transmission more reliable of rubber tile;
The utility model is simple in structure, and modern design makes rubber layer stressed more even, and its vertical carrying is more reliable, and the horizontal force transmission is more stable, installs more conveniently, and it is reliable to have a power transmission, rotate flexible, characteristics such as supporting capacity is big, displacement is big, and anti-seismic performance is good.
