Description
Technical field
The present invention relates to the bridge earthquake resistance technical field, relate in particular to the compound bridge pier antidetonation of a kind of direction across bridge block structure.
Background technology
In earthquake, bridge mainly receive horizontal earthquake along bridge to and direction across bridge (to being meant 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 each other, and the side direction block destroys, and the beam accident takes place 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 be employed in bottom or the bridge pier of bridge superstructure, the method that the bent cap top is provided with 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 take place bigger relative displacement (100～200mm), and conventional antidetonation stop limits the generation of this big relative displacement.
Therefore, those skilled in the art is devoted to develop the compound abutment antidetonation of a kind of direction across bridge block structure, 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.
Summary of the invention
Because the above-mentioned defective of prior art; Technical problem to be solved by this invention provides the compound bridge pier antidetonation of a kind of direction across bridge block structure; Improve the shock resistance of bridge, solve the fall problem of beam and of bridge superstructure generation direction across bridge between bridge superstructure and the substructure bigger relative displacement space being provided at direction across bridge.
For realizing above-mentioned purpose, the invention provides the compound bridge pier antidetonation of a kind of direction across bridge block structure, comprise bridge pier, bearing cushion block and bridge superstructure, said bearing cushion block is arranged between said bridge pier and the said bridge superstructure; Wherein, also comprise weak block that is arranged on the said bridge pier and the strong block that is arranged on said bridge superstructure bottom; Said weak block is arranged on the outside of said bearing cushion block, and said weak block is higher than said bearing cushion block, and it is inboard that said strong block is arranged on said bearing cushion block; Said weak block and the setting of said bearing cushion block at grade, the spacing of said strong block and adjacent said bearing cushion block is greater than the distance of block a little less than said and said bridge superstructure.
Preferable, said weak block and said bridge pier are Construction integration.
Preferable, said strong block and said bridge superstructure are Construction integration.
Preferable, said strong block and said weak block are two.
Preferable, the distance of said weak block and said bridge superstructure outer rim is 20-50mm, the distance of said strong block and adjacent said bearing cushion block is 100-200mm.
The invention has the beneficial effects as follows:
The present invention 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 is the weak block of bump earlier, and shear failure takes place earlier weak block; Thereby give between bridge superstructure and the bridge pier and produced necessary relative displacement space, discharge the part seismic energy simultaneously; After weak block is destroyed, then play 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 present invention also has simple in structure, the characteristics of easy construction.
Below will combine accompanying drawing that the technique effect of design of the present invention, concrete structure and generation is described further, to understand the object of the invention, characteristic and effect fully.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention.
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
Like Fig. 1, shown in Figure 2, a specific embodiment of the compound bridge pier antidetonation of direction across bridge of the present invention block 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 is provided with 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 said 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.
As shown in Figure 3 again, 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 preferable 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 preferable scope is 20-50mm.
Antidetonation block structure of the present invention also can be applied on the abutment.
Exemplary, following as the further application note of present embodiment:
Under the normal operating condition, in two outsides bridge superstructure is protected at direction across bridge, guarantee that bridge superstructure the beam problem can not occur falling by weak block.
Suffering under the earthquake state; Bridge superstructure moves at direction across bridge, and weak block and bearing cushion block collide each other, and shear failure takes place earlier weak block; Thereby give between bridge superstructure and the bridge pier and produced necessary relative displacement space, discharge the part seismic energy simultaneously; After weak block is destroyed, then played a role by strong block, strong block and the interaction of bearing cushion block have prevented that bridge from the direction across bridge beam that falls, further having improved the shock resistance of bridge at direction across bridge.
More than describe preferred embodiment of the present invention in detail.Be to be understood that; Those of ordinary skill in the art need not creative work just can design according to the present invention make many modifications and variation; Therefore; All technician in the art all should be in the determined protection domain by claims under this invention's idea on the basis of existing technology through the available technical scheme of logical analysis, reasoning, or a limited experiment.
