Abstract
The utility model discloses an anti-shock check block structure for a transverse bridge direction compound-type pier. The anti-shock check block structure for the transverse bridge direction compound-type pier comprises a pier, a support cushion block, a bridge superstructure, a weak check block and a strong check block. The support cushion block is arranged between the pier and the bridge superstructure. The weak check block is arranged on the pier and the strong check block is arranged at the bottom of the bridge superstructure. The weak check block is arranged outside the support cushion block and is higher than the support cushion block, and the strong check block is arranged inside the support cushion block. The weak check block and the support cushion block are arranged on a same plane. The distance between the strong check block and the adjacent support cushion block is bigger than the distance between the weak check block and the bridge superstructure. The anti-shock check block structure for the transverse bridge direction compound-type pier improves anti-shock ability of the bridge on the transverse bridge direction, solves falling beam problems in a transverse bridge direction happening on the bridge superstructure and provides large relative displacement space between the bridge superstructure and a bridge substructure.
Description
Technical field
The utility model relates to the bridge earthquake resistance technical field, relates in particular to the compound bridge pier Antivibration block of a kind of direction across bridge structure.
Background technology
In earthquake, bridge main to be subject to horizontal earthquake along bridge to and direction across bridge (to referring to bridge axis direction, direction across bridge refers to the direction perpendicular to the bridge axis along the bridge) effect of component.Have following potential safety hazard under the effect of direction across bridge component: the side direction block on bridge superstructure and the bridge pier (or abutment) collides mutually, and the side direction block destroys, and the beam accident occurs laterally to fall.
At present, prevent normal use and geological process under bridge superstructure generation direction across bridge fall on the problem of beam, generally adopt in the bottom of bridge superstructure or method that bridge pier, bent cap top arrange block solves the problems referred to above.Usually stay the gap about 30mm between block and the bridge construction.
Subtract the bridge construction of vibration-isolating system for employing, under the direction across bridge geological process as will give full play to the performance that subtracts vibration-isolating system, then need between bridge superstructure and the substructure to occur larger relative displacement (100～200mm), and conventional Antivibration block has limited the generation of this larger relative displacement.
Therefore, those skilled in the art is devoted to develop the compound bridge abutment anti-seismic stop block structure of a kind of direction across bridge, guarantees that bridge construction keeps good performance at normal operating condition with under the lateral seismic effect; Not only to solve the fall problem of beam of bridge superstructure generation direction across bridge, also will give full play to its performance for bridge upper and lower part structure provides necessary relative displacement space to make to subtract vibration-isolating system.
The utility model content
Because the defects of prior art, technical problem to be solved in the utility model provides the compound bridge pier Antivibration block of a kind of direction across bridge structure, improve bridge in the shock resistance of direction across bridge, solve the fall problem of beam and for larger relative displacement space is provided between bridge superstructure and the substructure of bridge superstructure generation direction across bridge.
For achieving the above object, the utility model provides the compound bridge pier Antivibration block of a kind of direction across bridge structure, comprises bridge pier, bearing cushion block and bridge superstructure, and described bearing cushion block is arranged between described bridge pier and the described bridge superstructure; Wherein, also comprise the weak block that is arranged on the described bridge pier and the strong block that is arranged on described bridge superstructure bottom; Described weak block is arranged on the outside of described bearing cushion block, and described weak block is higher than described bearing cushion block, and it is inboard that described strong block is arranged on described bearing cushion block.
Better, described weak block and the setting of described bearing cushion block at grade, the spacing of described strong block and adjacent described bearing cushion block is greater than the distance of block a little less than described and described bridge superstructure.
Better, described weak block and described bridge pier are integrated structure.
Better, described strong block and described bridge superstructure are integrated structure.
Better, described strong block and described weak block are two.
Better, the distance of described weak block and described bridge superstructure outer rim is 20-50mm, the distance of described strong block and adjacent described bearing cushion block is 100-200mm.
The beneficial effects of the utility model are:
The utility model under the normal operating condition, places the bearing cushion block outside by weak block owing to adopted the said structure design, and bridge superstructure is protected at direction across bridge, guarantees that bridge superstructure the beam problem can not occur falling.Under geological process, bridge superstructure moves at direction across bridge, and bridge superstructure clashes into first weak block, and shear failure occurs first weak block, thereby give between bridge superstructure and the bridge pier and produced necessary relative displacement space, discharge simultaneously the part seismic energy; After weak block is destroyed, then played a role by strong block, strong block and bearing cushion block interact, and have further improved the shock resistance of bridge at direction across bridge.
Simultaneously, the utility model also has simple in structure, the characteristics of easy construction.
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand fully the purpose of this utility model, feature and effect.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the present utility model.
Fig. 2 is the A-A schematic cross-section of Fig. 1.
Fig. 3 is the local enlarged diagram in B place of Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, a specific embodiment of the compound bridge pier Antivibration block of the utility model direction across bridge structure comprises bridge pier 1, bearing cushion block 3 and bridge superstructure 2, and bearing cushion block 3 is arranged between bridge pier 1 and the bridge superstructure 2.
Wherein, present embodiment also comprises the weak block 4 that is arranged on the bridge pier 1, and the strong block 5 that is arranged on bridge superstructure 2 bottoms; As shown in the figure, weak block 4 is positioned at the outside of bearing cushion block 5, and weak block 4 is higher than bearing cushion block 3, and strong block 5 is arranged on the inboard of bearing cushion block.
Concrete, weak block 4 arranges at grade with bearing cushion block 3, and the spacing L2 of strong block 5 and adjacent bearing cushion block is greater than the distance of weak block 4 with described bridge superstructure L1.
As depicted in figs. 1 and 2, two strong blocks 5 place the inboard of two bearing cushion blocks 3, and two weak blocks 4 are separately positioned on the edge, the left and right sides of bridge pier 1.
Again as shown in Figure 3, in the specific embodiment, strong block 5 is 100mm with the spacing L2 of adjacent bearing cushion block 3; Weak block 4 is 30mm with the distance L 1 of bridge superstructure 2.
In other embodiments, strong block 5 can also be other length such as 150mm or 200mm with the spacing L2 of adjacent bearing cushion block 3, and better scope is 100-200mm; Weak block 4 can also be other length such as 20mm or 50mm with the distance L 1 of bridge superstructure 2, and better scope is 20-50mm.
