Abstract
The utility model belongs to the technical field of a support seat, and discloses a self energy release bridge earthquake resistance support seat which is mainly technically characterized in that an upper seat plate, a middle seat plate and a lower seat plate are included, and the lower part of the upper seat plate is connected with an annular or a strip earthquake resistance blocking piece by a shearing screw rod. The earthquake resistance structure of the self energy release bridge earthquake resistance support seat adopts a horizontal force shearing device to cause the annular or the strip earthquake resistance blocking piece to be fixed with the upper seat plate by the shearing screw rod. Under the condition that an earthquake does not occur, the bearing force and the horizontal force resistance of the support seat satisfy the technical requirements of an ordinary spheroidal support seat. When the earthquake occurs, and strong horizontal force is generated, the lower support seat squeezes the earthquake resistance blocking piece. When the squeeze pressure exceeds a set value, the shearing screw rod is shorn, the shearing device fulfills the effectiveness, and the earthquake load is released to fulfill the protection function to a beam body and a bridge pier.
Description
Technical field
The utility model belongs to the bearing technical field, relates in particular to a kind of from releasing the energy bridge girder anti-seismic bearing.
Background technology
In the design and construction of bridge and other building, bearing need be set carry out pressure-bearing and transmit horizontal force.The spherical bearing of current use, its structure comprise upper base plate, middle seat board and following seat board, are respectively arranged with sliding friction pair between upper base plate, following seat board and middle seat board, are provided with integrally manufactured with it spacing block piece in the bottom of upper base plate.The bearing of this structure, because spacing block piece and upper base plate are connected as a single entity, when situations such as earthquake took place, seismic (seismal discharged nowhere, easily beam body and bridge pier was produced destruction.
The utility model content
Problem to be solved in the utility model just provides releasing certainly that a kind of seismic (seismal can discharge can bridge girder anti-seismic bearing.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise upper base plate, middle seat board and following seat board, the bottom of described upper base plate is connected with the antidetonation block piece by the shearing resistance screw rod.
Its additional technical feature is: described antidetonation block piece is ring-like; Described antidetonation block piece is a stripe shape; The close seat board down of described antidetonation block piece.
Provided by the utility model a kind of from releasing the energy bridge girder anti-seismic bearing, compared with prior art, earthquake resistant structure adopts the horizontal force clipping apparatus that possesses limited shearing resistance function, and ring-like or stripe shape antidetonation block piece are fixed by shearing resistance screw rod and upper base plate.Do not taking place under the seismic condition, the bearing capacity of bearing, horizontal force resistant satisfy the technical requirements of common spherical bearing.When earthquake takes place, have when horizontal force produces by force, following seat board extruding antidetonation block piece, when extruding force surpassed setting value, the shearing resistance screw rod was cut off, and clipping apparatus generation effectiveness, seismic (seismal obtain release, and beam body and bridge pier are played a protective role.
Description of drawings
Fig. 1 is a kind of from a kind of structural representation of releasing the energy bridge girder anti-seismic bearing for the utility model;
Fig. 2 is a kind of another kind of structural representation of releasing the energy bridge girder anti-seismic bearing certainly.
The specific embodiment
Below in conjunction with accompanying drawing a kind of structure and principle of releasing the energy bridge girder anti-seismic bearing certainly provided by the utility model is described in further details.
As shown in Figure 1, a kind of releasing certainly provided by the utility model can comprise upper base plate 1, middle seat board 2 and following seat board 3 by bridge girder anti-seismic bearing, and upper base plate 1 bottom is connected with the close ring-like antidetonation block piece 5 of seat board 3 down by shearing resistance screw rod 4.
As shown in Figure 2, a kind of releasing certainly can comprise upper base plate 1, middle seat board 2 and following seat board 3 by bridge girder anti-seismic bearing, and upper base plate 1 bottom is connected with the close stripe shape antidetonation block piece 5 of seat board 3 down by shearing resistance screw rod 4, and antidetonation block piece 5 is two.
In the use,,, use the bearing of Fig. 2 structure at the monodisplacement place at the bearing of non-displacement fixed end use Fig. 1 structure according to different needs.Do not taking place under the seismic condition, the bearing capacity of bearing, horizontal force resistant satisfy the technical requirements of common spherical bearing.When earthquake takes place, have when horizontal force produces by force, following seat board 3 extruding antidetonation block pieces 5, when extruding force surpassed setting value, shearing resistance screw rod 4 was cut off, and clipping apparatus generation effectiveness, seismic (seismal obtain release, and beam body and bridge pier are played a protective role.
