Description
Technical field
It the utility model is related to antivibration area, and in particular to a kind of shearing force tenon.
Background technology
Overpass, railway or bridge are formed by more bridge pier supporting bridges, in order to strengthen the security of bridge,
The shearing force tenon of vibration absorber and horizontal force of preventing is installed generally between bridge and bridge pier.
The horizontal force but the shearing force tenon generally used now rod iron that typically utilization is fixed between bridge and bridge pier is prevented,
Because rod iron is typically embedded between bridge and bridge pier, its installation accuracy and gap are not easy to grasp, and error is larger, is not suitable for
The Structural Engineering of system is told in modernization, and lifting surface area is small, discontinuity, easily causes the difficulty on design and construction,
And due to being chronically exposed to wild environment, life consumption is fast.
The content of the invention
Deficiency of the purpose of this utility model aiming at above-mentioned technology, there is provided a kind of shearing force tenon, precision is accurate, construction
It is convenient, the horizontal force that can effectively prevent between bridge and bridge pier, and not by environmental disturbances.
To achieve the above object, the shearing force tenon designed by the utility model, including what is be oppositely arranged are bolted
Lower slider plate and the upper sliding plate for being bolted on anchorage rod iron bottom, the lower slider on lower anchorage rod iron top
The upper surface of plate is provided with lower guideway bar assembly, and the lower surface of the upper sliding plate is provided with upper rail bar, the lower guideway bar assembly
Including two lower guideway bars, two lower guideway bar formation chutes arranged in parallel, the upper rail bar is located in the chute.
Preferably, dust-proof enclosing, the top of the dust-proof enclosing are provided between the upper sliding plate and the lower slider plate
It is fixed by screws on the outward flange of the upper sliding plate, the dust-proof enclosing prevents dust from entering the lower guideway bar assembly
It is interior, in order to avoid influence the performance of trip.
Preferably, the bottom of the upper rail bar and the chute is provided with gap, and the gap is 5~40mm, between described
Gap avoids trip and bears vertical force.
Preferably, the upper sliding plate upper surface is provided with pressing plate.
The utility model compared with prior art, has advantages below：
1st, by the upper rail bar and lower guideway bar assembly that are engaged, design and construction precision is improved, is effectively disappeared
Remove the horizontal force between bridge and bridge pier；
2nd, prevent dust from entering in lower guideway bar assembly by dust-proof enclosing, in order to avoid influenceing the performance of trip, improve trip
Working life, not by environmental disturbances.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model shearing force tenon；
Fig. 2 is Fig. 1 schematic top plan view.
Each part numbers are as follows in figure：
Bolt 1, lower anchorage rod iron 2, lower slider plate 3, upper anchorage rod iron 4, upper sliding plate 5, lower guideway bar assembly 6, on lead
Rail bar 7, lower guideway bar 8, chute 9, dust-proof enclosing 10, screw 11, gap 12, pressing plate 13.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figures 1 and 2, anchorage under the utility model shearing force tenon, including being bolted on being oppositely arranged
The lower slider plate on rod iron top and the upper sliding plate for being bolted on anchorage rod iron bottom, the upper surface of lower slider plate is set
There is a lower guideway bar assembly, the lower surface of upper sliding plate is provided with upper rail bar, and lower guideway bar assembly includes two lower guideway bars, two
Lower guideway bar formation chute arranged in parallel, upper rail bar are located in chute, and the bottom of upper rail bar and chute is provided with gap, this reality
It is 5mm to apply an intermediate gap, avoids trip and bears vertical force.
Meanwhile dust-proof enclosing is provided between upper sliding plate and lower slider plate, the top of dust-proof enclosing is fixed by screws in
On the outward flange of upper sliding plate, prevent dust from entering in lower guideway bar assembly, in order to avoid influence the performance of trip.
In addition, upper sliding plate upper surface is provided with pressing plate.
During utility model works, when upper sliding plate and lower slider plate bear the horizontal shear parallel with upper rail bar,
Upper rail bar slides in chute；When upper sliding plate and lower slider plate bear the horizontal shear vertical with upper rail bar, above lead
Rail bar and chute, which coordinate, positions and bears horizontal shear effect.
The utility model shearing force tenon improves design and construction by the upper rail bar and lower guideway bar assembly that are engaged
Precision, the horizontal force effectively prevented between bridge and bridge pier；And prevent dust from entering lower guideway bar group by dust-proof enclosing
In part, in order to avoid influenceing the performance of trip, trip working life is improved, not by environmental disturbances.
