Description
Technical field
The utility model relates to highway bridge field, especially a kind of bridge pad.
Background technique
Bridge pad is the Force transmission parts being arranged between bridge span structure and bridge pier or abutment, in use, it is necessary to
It is required that contacting with girder closely, it is otherwise unable to reach the predeterminated target of power transmission.Currently, on highway and municipal works, it is especially high
It builds bridge in the majority using structures such as cored slab, small box girders, and this kind of bridge structure is often the most economical using laminated rubber bearing
With it is convenient, laminated rubber bearing is widely used in this kind of bridge structure.
In recent years, as China's highway, local state provincial highway bridge build up the operation of rear many years, Partial Bridges support goes out
The diseases such as existing support cushion block broken invalid, seat empty, the generation of such disease can change bridge structure boundary condition, to bridge
Structure stress and globality are unfavorable, serious to result even in bridge security accident.
Spherical bearing is a kind of novel bridge support to grow up on the basis of pot rubber bearing, has horizontal turn
The characteristics of angle is big, high-bearing capacity, abrasion performance.The corner of spherical bearing is by the opposite sliding between spherical crown and spherical surface come real
Existing, the horizontal displacement of support is realized in the opposite sliding between plane tetrafluoro plate and stainless steel plate, resists ground by basin ring or baffle
The horizontal force action of shake can effectively resist horizontal earthquake power in low land earthquake degree area.In existing one-way movable ball-type branch
On seat, upper bracket plate directly contacts transmitting horizontal force with lower support plate, and slide plate and stainless steel plate is arranged to adapt to support in contact surface
Displacement request.When beam-ends rotates, upper bracket plate and lower support plate no longer keeping parallelism state, so that slide plate and stainless steel
The contact of plate becomes line contact from face contact, causes the uneven stress of sled surface, causes to squeeze brokenly ring.
Referring to Figure 1, notification number is that the Chinese utility model patent of CN204662253U discloses a kind of railroad bridge ball
Fashioned iron support, including upper base plate 1, lower seat board 2, middle seat board 3, spherical panel 4, surface plate 5 and sealed skirt 6, the middle seat
Plate 3 is mounted between upper base plate 1 and lower seat board 2, and the surface plate 5 is mounted between upper base plate 1 and middle seat board 3, described
Spherical panel 4 is mounted between middle seat board 3 and lower seat board 2, and the sealed skirt 6 is wrapped in the upper of middle seat board 3 and lower seat board 2
Portion has the effect of dust-proof.The bottom of the middle seat board 3 and spherical panel 4 is arc-shaped structure, can bear vertical lotus
Carry and it is each be a kind of bi-directional movable support to rotational kinetic energy, have multidirectional displacement performance.Further, the sealed skirt 6
Top is provided with circular arc chamfering, can better adapt to the needs of support big corner.Further, the railroad bridge ball
Fashioned iron support further includes slide plate 7, and the slide plate 7 is mounted between upper base plate 1 and surface plate 5, with common pot rubber bearing
It compares, corner is bigger, rotates the features such as flexible, bearing capacity is big, Admissible displacement amount is big.
Prior art bridge pad can not can be closely affixed with bridge bottom surface, effective stress.
