The practical bridge deck pavement layer shearing tester comprises a frame, a lower-layer clamping plate, an upper-layer clamping plate, a horizontal force hydraulic loading device and a vertical force lever loading device, wherein one end of the horizontal force hydraulic loading device is connected with the frame, and the other end of the horizontal force hydraulic loading device is connected with one end of the upper-layer clamping plate through a force sensor device; the lower-layer clamping plate fixed on the frame is arranged below the upper-layer clamping plate, and the vertical force lever loading device is arranged above the upper-layer clamping plate; the side face of the lower-layer clamping plate is provided with a displacement sensor device; the displacement sensor device is contacted with the side face of the upper-layer clamping plate; and a display screen is connected outside the force sensor device. According to the practical bridge deck pavement layer shearing tester, the manufacturing process of a test piece in a bridge deck pavement layer shearing test can be simplified, and the treatment on the plate interlayer surface and the influence of the longitudinal slope of the bridge on interlayer shear stress are comprehensively considered.
Description
Technical field
The utility model relates to highway bridge deck paving technical field, relates in particular to practical bridge deck pavement shearing test apparatus.
Background technology
Existing deck paving is sheared the used test specimen of instrument and is needed to prepare the rectangular parallelepiped test specimen with the rut test piece make-up machine earlier, and the back is equipped with standard core test specimen, test material preparation complex procedures with boring core mechanism; Standard core test specimen diameter has only 100mm, because the core size is less, can not objectively respond between flaggy face process to the influence of interlayer shearing stress; Existing simultaneously shearing instrument is not considered the influence of bridge longitudinal gradient to the bridge deck pavement inter-laminar stress.
Summary of the invention
The utility model technical matters to be solved provides a kind of preparation process of simplifying bridge deck pavement shear test test specimen, take all factors into consideration face deal with between flaggy and the bridge longitudinal gradient practical bridge deck pavement shearing test apparatus to the influence of interlayer shearing stress.
For addressing the above problem, the described practical bridge deck pavement shearing test apparatus of the utility model is characterized in that: it comprises framework, following laminated plank, goes up laminated plank, horizontal force hydraulic loading device and vertical force lever loading device; One end of said horizontal force hydraulic loading device links to each other with said framework, and its other end links to each other with a said end of going up laminated plank through the force transducer device; Said below of going up laminated plank is provided with the said laminated plank down that is fixed on the said framework, and its top is provided with said vertical force lever loading device; The said side of laminated plank down is provided with displacement sensor device, and this displacement sensor device and the said flanked that goes up laminated plank are touched; Said force transducer device externally connected with display screen.
Said laminated plank down is provided with 5% the gradient.
The utility model compared with prior art has the following advantages:
1, the used test specimen processing technology of the utility model is simple; Only need to use the rut test piece make-up machine; Sample dimensions is 300 * 300 * 100mm, not only simplifies the preparation process of bridge deck pavement shear test test specimen, and can objectively respond between flaggy face process to the influence of interlayer shearing stress.
2, the utility model following laminated plank of having a gradient can reflect the influence of bridge longitudinal gradient to the bridge deck pavement inter-laminar stress.
3, the utility model is high to the bridge stressed simulation degree of layer of mating formation, and practicality is good, is easy to promote.
