The combined windproof support is mainly characterized by comprising an upper seat plate and a lower seat plate with an outer basin cavity; a steel liner plate, a rubber damping plate and an inner basin with an inner basin cavity are arranged between the upper seat plate and the lower seat plate; a sliding plate is arranged between the upper seat plate and the steel liner plate; the bottom of the steel liner plate is provided with a convex edge matched with the inner wall of the inner basin cavity; the convex edge and the rubber damping plate are arranged in the inner basin cavity of which the bottom is provided with a boss; a cavity internally provided with a disc spring and matched with the boss is arranged at the upper part of the lower seat plate; a press ring is connected with the lower seat plate by a limiting bolt with a damping spring; the inside of the press ring is contacted with the convex edge; a sliding friction pair is arranged between the inside face of the outer basin cavity and the outside face of the inner basin cavity. According to the combined windproof support, a rubber pad and the inner basin do not move relative to each other when the support is elastically compressed to generate relative displacement, so the abrasion problem of the rubber plate is solved.
Description
Technical field
The utility model belongs to the bridge pad technical field, relates in particular to a kind of Combined anti-wind bearing.
Background technology
Since the eighties in 20th century, China has built up or has built or planning to build the bridge of a collection of large span, because these grand bridges obviously have large, light, gentle characteristics, very responsive to wind action, wind load has become overriding load, this just requires the bridge of large span that wind-proof device must be set, and wind-resistant support is exactly a kind of of Wind-resistance of Bridges device.
The impact of carrying due to wind, during bridge is in all the time and vacillates now to the left, now to the right, this just requires wind-resistant support that certain compressive strain need to be arranged, so that the buffering bridge is to the impact of pier or abutment, but this wobble frequency is very high, directly cause rubber tile in seat structure in the friction repeatedly with the bearing tub wall, and then make the rubber tile wearing and tearing, affect the normal function of bearing.
The utility model content
The technical problems to be solved in the utility model just be to provide a kind of when the bearing elastic compression produces relative displacement rubber pad and interior basin without relative motion, solved the Combined anti-wind bearing of the wear problem of rubber tile.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise upper base plate, lower seat board with outer pelvic cavity, be provided with steel liner plate between described upper base plate and lower seat board, rubber damping plate and with the interior basin of interior pelvic cavity, be provided with slide plate between upper base plate and steel liner plate, the steel liner plate bottom is provided with the flange be complementary with interior pelvic cavity inwall, flange and rubber damping plate are in interior pelvic cavity, the bottom of interior basin is provided with boss, the top of lower seat board is provided with the cavity of the built-in dish spring be complementary with boss, pressure ring is connected with lower seat board by the caging bolt with shock-absorbing spring, pressure ring is inboard to contact with flange, be provided with sliding friction pair between the medial surface of outer pelvic cavity and the lateral surface of interior pelvic cavity.
Its additional technical feature is: the outer rim place of described rubber damping plate is provided with the brass sealing ring.
Combined anti-wind bearing provided by the utility model, compared with prior art, be provided with interior basin in lower seat board, the top of lower seat board is provided with the cavity be complementary with interior basin boss, is provided with multi-disc dish spring between cavity and boss, when Bearing Seat Force compresses, boss is pressed in the cavity of lower seat board by the dish spring, after pressure is eliminated, boss returns to original position by the extension of dish spring again, has realized the compressive strain of big displacement quantity and has set back; The lateral surface that the medial surface of outer pelvic cavity arranges chromium coating or coats corrosion resistant plate, interior pelvic cavity arranges the polytetrafluoroethylene (PTFE) slide plate, both form sliding friction pair, when the bearing elastic compression produces relative displacement, rubber pad and interior basin, without relative motion, have solved the wear problem of rubber tile.
Pressure ring adopts caging bolt to be connected with lower seat board, and be provided with shock-absorbing spring between pressure ring and caging bolt, caging bolt is through shock-absorbing spring, pressure ring is screwed into lower seat board end face, caging bolt presses certain pretightning force to shock-absorbing spring, pressure ring is inboard to contact with flange, the pressure ring bottom is cannelure, the end face of cannelure and outer pelvic cavity end face have certain distance, when bearing compressive strain, pressure ring is because the flange of the pretightning force that is subject to shock-absorbing spring along with steel liner plate moves downward, until pressure ring pushes up on outer pelvic cavity end face, when bearing recovers distortion, the bearing potential energy that compression produces by the dish spring moves upward, arrive after initial position because inertia will move upward, at this moment the shock-absorbing spring of caging bolt bottom starts compression, shock-absorbing spring is again by storage of potential energy, potential energy by shock-absorbing spring after pressure ring and steel liner plate stop moving upward returns to initial position, avoided directly mutually impacting between steel part, damping effect impact-absorbing kinetic energy by shock-absorbing spring, make the Bearing Seat Force balance.
