Description
Technical field
The utility model belongs to highway experimental technique field, is specifically related to a kind of test unit of novel analog thin overlay interlayer shear.
Background technology
In long-term working practice, in highway early disease preventive maintenance, thin overlay is widely used because of the advantage of its uniqueness, but whether thin overlay technology application success is not only how to prepare superior in quality finishing coat asphalt, more importantly how to be tightly combined with old pavement layer by finishing coat.Most of thin overlay structural failure is inter-laminar shear failure.Domestic evaluation of cutting ability about thin overlay shearing strength at intersection at present adopts direct shear test more, adopts and makes cylinder specimen, after health, requires cutting sample, then put into controllable temperature environment according to physical size, measure the shearing strength of interlayer.Though this kind of method can evaluate the anti-shear ability of interlayer more accurately, but its can only imitation specimen a direction stress destruction situation, the more important thing is that this kind of method supposes is completely continuous contact condition between each structural sheet, can not the boundary condition of simulated roadway structure reality, thus under making the result that measures and actual condition the anti-shear ability of structure there is some difference.
Summary of the invention
The purpose of this utility model is: simple in order to solve this apparatus structure, solve test specimen one direction in test in the past stressed, can not the problem of simulated roadway structure actual boundary condition.Be in semicontinuous state between each structural sheet of test specimen in warranty test process, improve the degree of accuracy of test simulation condition, its technical scheme is as follows simultaneously:
A kind of test unit of novel analog thin overlay interlayer shear, it comprises pressing machine 1, upper grip 2, lower chuck 3, upper padding plate 4, lower bolster 5, roller bearing 6, fastening bolt 7, force snesor 8, it is characterized in that: in described device, subordinate's top end surface middle is fixedly connected with force sensor 8, on described force snesor 8, top end surface is fixedly connected with lower bolster 5, and described lower bolster 5 is mutually permanently connected by wearing pin with described force snesor 8, on described lower bolster 5, the inner average mark of top end surface is furnished with several roller bearings 6, on described lower bolster 5, top end surface is fixedly connected with lower chuck 3, on described lower chuck 3, top end surface is placed with upper grip 2, on described upper grip 2, top end surface is fixedly connected with upper padding plate 4, under the right top end surface of described upper grip 2, lower edge place and lower chuck 3 left top end surface top edges place are respectively fitted with fastening bolt 7, on described device inside, top end surface middle is fixedly connected with pressing machine 1, top end surface shape triangular in shape on described upper grip 2 and described lower chuck 3, and described upper grip 2 and described lower chuck 3 apparent surface middle are respectively provided with standing groove, and described upper grip 2 and described lower chuck 3 outer tip end surface middle are fitted with fastening bolt 7, and described fastening bolt 7 penetrates described upper grip 2 and described lower chuck 3 inserts in described standing groove, on described upper padding plate 4 times top end surfaces and lower bolster 5, top end surface average mark is furnished with several grooves, and each described inside grooves is placed with roller bearing 6.
The beneficial effects of the utility model are: this apparatus structure is simple, solve test specimen one direction in test in the past stressed, can not the problem of simulated roadway structure actual boundary condition.Be in semicontinuous state between each structural sheet of test specimen in warranty test process simultaneously, improve the degree of accuracy of test simulation condition.
