The support frame has the advantages that the structure is simple, the operation is convenient, a core sample, a steel pad strip and a ternary plate pad strip are ensured not to roll through using the support frame for fixing the core sample, the steel pad strip and the ternary plate pad strip, and the work efficiency and the test accuracy are improved.
Description
Technical field
The utility model relates to the test tools made of mechanical performance of concrete, specifically is a kind of concrete split tensile strength test support.
Background technology
Because the complicacy of equipment and loading, structural concrete axial tensile strength and flexural tensile strength often are difficult to obtain by testing directly, are to utilize the concrete split tensile strength to convert in the time of more.Carrying out split tensile strength when test, be on two relative buses of concrete core sample, to place three-ply board filler strip, steel filler strip, add then, lower platen that loading to concrete core sample is split.Because it all is that circular arc contacts circular arc that two steel filler strips contact with the core bus, and upper and lower of steel filler strip and core also will be placed the three-ply board filler strip, therefore not only core rolls easily, filler strip also is difficult for being put into just on two relative buses of core, cause inefficiency, accuracy also is difficult to guarantee.Split in the daraf(reciprocal of farad) technical regulation and to require to come ancillary test, but do not provide the specific practice of support with support.
The utility model content
The technical problems to be solved in the utility model provides a kind of concrete split tensile strength test support, and warranty test easy to operate improved work efficiency and the test accuracy tested.
The technical solution of the utility model is:
Concrete split tensile strength test support, comprise top board, lower platen, between the upper and lower pressing plate and the two ends that are positioned at upper and lower pressing plate are connected with X-shaped movable support frame I and X-shaped movable support frame II respectively, be respectively arranged with upper hopper chute and gliding groove on the lower surface of described top board and the upper surface of lower platen, upper hopper chute is provided with anchor clamps, and gliding groove is provided with lower clamp.
Be connected with core backstay I and core backstay II between described X-shaped movable support frame I and the X-shaped movable support frame II.
The two ends of described core backstay I and core backstay II all are installed on the bottom of X-shaped movable support frame I and X-shaped movable support frame II.
The two ends of described top board are provided with the axle sliding tray, the two ends of lower platen are provided with the lower shaft sliding tray, the two ends of axle are arranged in the sliding tray on two supports, the two ends of two support lower shafts are arranged in the lower shaft sliding tray, the top of X-shaped movable support frame I and X-shaped movable support frame II is rotated and is installed on the support on the axle, and the bottom of X-shaped movable support frame I and X-shaped movable support frame II is rotated and is installed on the support lower shaft.
The beneficial effects of the utility model:
The utility model is lived the steel filler strip by the chute engaging, again by the fixing position of steel filler strip and three-ply board filler strip of anchor clamps, and pass through the fixedly position of core of core backstay, guarantee that core, steel filler strip, three-ply board filler strip can not roll in the test, improved the accuracy of work efficiency and test.
