Abstract
The utility model provides a clamp device for a splitting test of a concrete cube test piece. The clamp device comprises an upper bearing board and a lower bearing board, which are connected through stand columns, wherein an upper arc-shaped steel filler strip is arranged on the upper bearing board; the upper arc-shaped steel filler strip is provided with an upper positioning sheet for positioning an upper hard fiber cushion layer; a lower arc-shaped steel filler strip is arranged on the lower bearing board; the lower arc-shaped steel filler strip is provided with a lower positioning sheet for positioning a lower hard fiber cushion layer. When the clamp device is used for testing, the test piece can be directly put into a clamp without scribing; the test piece can be centered through a centering steel sheet; the upper and the lower hard fiber cushion layers are respectively put into an inserting hole of the upper positioning sheet and a slot of the lower positioning sheet, so that the test can be carried out. The device has the characteristics of simple structure, convenience in operation and high reliability.
Description
Technical field
The utility model relates to a kind of test unit, especially relates to a kind of concrete cube test specimen diametral compression test grip device.
Background technology
In practice at present, concrete cube test specimen, in the time carrying out diametral compression test, first will mark the position line of splitting surface on test specimen, then test specimen, steel filler strip and hard fibre bed course is placed on pressure testing machine, and test specimen is carried out to geometry centering, make splitting surface vertical with pressure direction.Owing to manually directly filler strip and hard fibre bed course being placed on pressing machine, easily make splitting surface and pressure direction out of plumb, affect test accuracy.
Utility model content
The utility model relates to a kind of concrete cube test specimen diametral compression test grip device, utilizes this device can measure the tensile splitting strength of concrete cube test specimen.Its technical scheme is as described below:
A kind of concrete cube test specimen diametral compression test grip device, comprise the upper bearing plate being connected by column, lower bearing plate, described upper bearing plate is provided with arc-shaped steel filler strip, described upper arc-shaped steel filler strip is provided with the upper spacer for locating upper hard fibre bed course, described lower bearing plate is provided with arc lower steel filler strip, and described arc lower steel filler strip is provided with the lower spacer for locating lower hard fibre bed course.
The height of described column can regulate, and is provided with the convenient spring that test specimen is installed.
Described arc lower steel filler strip is also provided with centering steel disc, for making test specimen placed in the middle.
Described upper spacer is arranged on the two ends of upper steel filler strip, and described lower spacer is arranged on the two ends of bottom steel filler strip.
Described upper spacer is provided with can be to the jack of upper hard fibre bed course location, and described lower spacer is provided with can be to the slot of lower hard fibre bed course location.
Described concrete cube test specimen diametral compression test grip device is simple in structure, easy to operate, and reliability is high.
Accompanying drawing explanation
Fig. 1 is the concrete cube test specimen diametral compression test grip device structural representation that the utility model provides;
In figure, 1, upper bearing plate; 2, lower bearing plate; 3, spring; 4, column; 5, upper arc-shaped steel filler strip; 6, arc lower steel filler strip; 7, upper spacer; 8, lower spacer; 9, upper hard fibre bed course; 10, lower hard fibre bed course; 11, centering steel disc; 12, concrete sample.
Embodiment
As shown in Figure 1, described concrete cube test specimen diametral compression test grip device comprises bearing plate 1, lower bearing plate 2, column 4, steel filler strip and centering steel disc 11, on described column 4, be provided with spring 3, to facilitate, test specimen 12 is installed, the height of described column 4 can regulate to adapt to unconventional test specimen to carry out test specimen.
Be provided with spacer 7 at the two ends of upper arc-shaped steel filler strip 5, the jack on upper spacer 7 can be located upper hard fibre bed course 9; Be provided with lower spacer 8 at the two ends of arc lower steel filler strip 6, the slot on lower spacer 8 can be located lower hard fibre bed course 10.
Described upper arc-shaped steel filler strip 5 and arc lower steel filler strip 6 are shaped as arc, and centering steel disc 11 is arranged on arc lower steel filler strip 6, and described centering steel disc 11 launches to both sides, can block test specimen.
Described centering steel disc 11, for making test specimen placed in the middle, can guarantee that by upper spacer 7,8 of lower location the splitting surface of test specimen 12 is vertical with pressure direction.
When test, first device is placed on pressure testing machine, without line on test specimen 12, directly test specimen 12 is put into fixture, centering steel disc 11 just can make test specimen 12 centerings.Then upper hard fibre bed course 9, lower hard fibre bed course 10 are put into respectively to the jack of upper spacer 7 and the slot of lower spacer 8, just can test.After having tested, upper hard fibre bed course 9, lower hard fibre bed course 10 are no longer reused.
For unusual formalism test specimen 12, can adjust the height of column 4, make the height between upper and lower hard fibre bed course 9,10 approach the size of test specimen 12, and then test.Described concrete cube test specimen diametral compression test grip device is simple in structure, easy to operate, and reliability is high.
