Description
Technical field
The present invention relates to bridge block technical field, it particularly relates to a kind of two-way preloading bridge block.
Background technology
With the continuous aggravation of China's protection against and mitigation of earthquake disasters situation and flourishing for bridge construction cause, engineering circles are increasingly
Pay attention to the anti-seismic performance of bridge.One of anti-seismic construction measure important as bridge, block have limitation bridge displacement, anti-falling stop
The function of beam, can effectively lift the anti-seismic performance of bridge.
Block is generally arranged at the pier position of bridge, for preventing the relative displacement between the structure of direction across bridge upper and lower part,
The problem of most of blocks all use concrete structure, poor there are ductile performance, and bearing capacity is not high, more it is worth noting that,
, should not be in bridge pier in some landscape bridges（Especially vase pier）Upper setting block.
However, setting block to need pre-buried block reinforcing bar in bridge superstructure bottom, and need in bridge pier and superstructure
Formwork supporting plate pours block concrete in narrow space before, therefore construction quality is difficult to ensure that.Under geological process, bridge block
Huge effect of impact is will suffer from, such as block quality existing defects, that is, is occurred once hitting broken situation, at the same time, earthquake
The stress of two-way concrete block is complicated under effect, and constitutive relation is indefinite, and great difficulty is caused for aseismatic analysis of bridges.
The problem of in correlation technique, not yet propose effective solution at present.
The content of the invention
For the above-mentioned technical problem in correlation technique, the present invention proposes a kind of two-way preloading bridge block, can not only
Stress is clear and definite, and easy to construct, the situation suitable for setting block in bridge superstructure bottom surface, effectively improves bridge earthquake resistance
Energy.
To realize above-mentioned technical purpose, the technical proposal of the invention is realized in this way：
A kind of two-way preloading bridge block, including anchoring piece and sliding part, the anchoring piece include anchor plate, the anchoring steel
Plate is connected with some anchor bolts, and is embedded in bridge superstructure bottom surface in advance, and middle partition plate is connected with the anchor plate, described
Middle partition plate is equipped with some ribbed stiffeners, and the sliding part includes some guide rods, and the left and right sides of the middle partition plate connects respectively
There is guide rod, described guide rod one end is connected with compression plate, is arranged with elastomeric element on the guide rod, outside the compression plate
Side bonds have the first sheet rubber.
Further, the guide rod is consolidated with middle partition plate crossed anchor.
Further, the front and rear sides of the middle partition plate and compression plate are bonded with the second sheet rubber.
Further, connected between the guide rod and middle partition plate by nut.
Further, gasket is installed between the nut and middle partition plate.
Further, the guide rod is between ribbed stiffener.
Further, the anchor bolt is located at the corner of anchor plate.
Further, the elastomeric element is spring.
Beneficial effects of the present invention：Can not only stress it is clear and definite, easy to construct, suitable for being set in bridge superstructure bottom surface
The situation of block is put, effectively improves anti-seismic performance of beam bridge.

Embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art's all other embodiments obtained, belong to what the present invention protected
Scope.
As shown in Figs 1-4, a kind of two-way preloading bridge block according to embodiments of the present invention, including anchoring piece and cunning
Moving part, the anchoring piece include anchor plate 6, and the durability of component is enhanced by anchor plate 6, reduce the later stage of component
Maintenance difficulty and expense, the anchor plate 6 are welded with some anchor bolts 1, and are embedded in bridge superstructure bottom surface in advance, described
Middle partition plate 5 is welded with anchor plate 6, the middle partition plate 5 is equipped with some ribbed stiffeners 11, and the sliding part includes some guiding
Bar 2, the left and right sides of the middle partition plate 5 are connected to guide rod 2, and described 2 one end of guide rod is connected with compression plate 8, institute
State and elastomeric element 7 is arranged with guide rod 2, the outside of compression plate 8 is bonded with the first sheet rubber 9, can be drawn from stress
The effect of impact of bridge superstructure is buffered by elastomeric element 7, while be aided with the first sheet rubber 9 of buffering to reduce shock
Power, avoids the failure of anchor plate 6.
In one particular embodiment of the present invention, the guide rod 2 intersects anchoring with middle partition plate 5, using this scheme, makes
Its overall structure is more firm.
In one particular embodiment of the present invention, the front and rear sides of the middle partition plate 5 and compression plate 8 are bonded with protection
Second sheet rubber 10, using this scheme, reduce further impact.
In one particular embodiment of the present invention, connected between the guide rod 2 and middle partition plate 5 by nut 3, its
In, elastomeric element 7 is realized pre-loaded by nut, using this scheme, is easily installed.
In one particular embodiment of the present invention, gasket 4 is installed between the nut 3 and middle partition plate 5, passes through gasket
The contact area of 4 increase nuts 3 and middle partition plate 5, reduces pressure.
In one particular embodiment of the present invention, the guide rod 2 is between ribbed stiffener 11.
In one particular embodiment of the present invention, the anchor bolt 1 is located at the corner of anchor plate 6, using its side
Case, increases overall stability.
In one particular embodiment of the present invention, the elastomeric element 7 is spring.
In order to facilitate understand the present invention above-mentioned technical proposal, below by way of in specifically used mode to the present invention it is above-mentioned
Technical solution is described in detail.
When specifically used, two-way preloading bridge block according to the present invention, two-way preloading bridge block is installed
In bridge superstructure bottom surface, gap is set to adapt to the opposite position of bridge normal operation stage therebetween between bridge pier
Move；Work as transversely acting（Such as lateral seismic effect, across-wind dynamic load, the effect of ship Transverse Impact）The pier beam of generation is laterally opposed
When displacement is more than above-mentioned preset clearance, two-way preloading bridge block starts to play a role：It is that compression plate 8 is compressed first, and then
Cross force is transmitted on bridge pier, due to the cushioning effect of 7 and first sheet rubber 9 of elastomeric element, which can't be notable
Increase；Secondly with the gradual increase of 7 decrement of elastomeric element, the load that two-way preloading bridge block is subject to also gradually increases,
The relative displacement of bridge pier and bridge gradually increases；Finally when cross force and two-way preloading bridge block are produced because elastomeric element 7 compresses
When raw resistance is equal, relative displacement no longer increases, after transversely acting, under the action of preloading elastomeric element 7, on
Portion's structure can realize a degree of reset.
In conclusion by means of the present invention above-mentioned technical proposal, can not only stress it is clear and definite, easy to construct, be suitable for
The situation of block is set in bridge superstructure bottom surface, effectively improves anti-seismic performance of beam bridge.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on, should all be included in the protection scope of the present invention god.
