The holder comprises an upper fixing frame and a lower fixing frame, wherein each of the upper fixing frame and the lower fixing frame is provided with an annular framework, bar bodies are symmetrically arranged on diameter extension lines of the annular frameworks, namely, one ends of the bar bodies are connected with the annular frameworks, through holes are formed in the other ends of the bar bodies, three locating holes are uniformly formed in the wall bodies of the annular frameworks, locating nails are mounted on the locating holes, pressure pins penetrate through the through holes in the lower fixing frame, discs are arranged on the tops of the pressure pins, the locating pins are in cone shapes with one thick ends and one thin ends, and the bar bodies and the annular frameworks are integrated. According to the holder, a to-be-tested piece is fixed at the centers of the annular frameworks through the upper fixing frame, the lower fixing frame, and the locating holes and locating nails of the upper fixing frame and the lower fixing frame, and a device for measuring is mounted and fixed on the through holes in the upper fixing frame, so that a deformation measuring device can be fixed on a test piece accurately and firmly and test precision is improved; and the device is simple in structure, easy to manufacture, and convenient to operate.

Description

A kind of indicator bracket for test splice stretcher strain
Technical field
The utility model relates to a kind of indicator bracket for test splice stretcher strain, measurement mechanism can be fixed on the test specimen to be measured the handled easily test.
Background technology
When test architecture is used the performance of reinforcing steel bar machinery jointing, except the test stretching resistance, the size that also needs test splice under certain pulling force, to be out of shape.During with this distortion of deformation measuring devices such as dial gauge or displacement meter test, deformation measuring device need be fixed on test specimen, this just needs a kind of stationary installation, is used for the indicator bracket of test splice stretcher strain.
Summary of the invention
The purpose of this utility model is for providing a kind of indicator bracket for test splice stretcher strain, and it is simple in structure, fixation, and accurate positioning, easy to operate.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of indicator bracket for test splice stretcher strain, comprise upper holder and lower fixed frame, described upper holder and lower fixed frame are equipped with an annulus framework, be arranged with the body of rod on the diameter extended line of annulus framework, be that the body of rod one end connects the annulus framework, the other end is provided with through hole; Evenly be provided with three pilot holes on the wall body of annulus framework, locating pin is installed on the pilot hole, pressure pin passes the through hole of lower fixed frame, and the top of pressure pin is provided with disk.
Described locating pin is taper, and an end is thick, an end taper.
The described body of rod and annulus framework are an integral body.
Described through hole is that two semi arches connect and compose by screw rod, and the diameter of this through hole matches with the fixed bar diameter of deformation measuring device.
The center that pilot hole and the locating pin of the utility model by upper holder and lower fixed frame and setting thereof is fixed on test specimen to be measured the annulus framework, to be fixed on the through hole of upper holder for the device of measuring, so can be precisely, securely deformation measuring device is fixed on the test specimen, improved test accuracy, and device is simple in structure, make easily, easy to operate.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is result of use figure of the present utility model.
Fig. 2 is vertical view of the present utility model.
Embodiment
As Fig. 1 or shown in Figure 2, the utility model comprises upper holder 1 and lower fixed frame 2, and described upper holder and lower fixed frame are equipped with an annulus framework 3, is arranged with the body of rod 4 on the diameter extended line of annulus framework, be that the body of rod one end connects the annulus framework, the other end is provided with through hole 5; Evenly be provided with three pilot holes 6 on the wall body of annulus framework 3, locating pin 7 is installed on the pilot hole, pressure pin 8 passes the through hole 5 of lower fixed frame 2, and the top of pressure pin is provided with disk 9.
Described locating pin 7 is taper, and an end is thick, an end taper; Used material hardness is higher than test specimen.
The described body of rod and annulus framework are an integral body.
Described through hole 5 is that two semi arches connect and compose by screw rod, and the diameter of this through hole matches with the fixed bar diameter of deformation measuring device.
When using the utility model, at first test specimen 10 to be measured is penetrated in the annulus framework 3 of upper holder 1 and lower fixed frame 2, by adjusting locating pin 7 that its chucking is fixing; Make the expansion end of deformation measuring device 11 downward then, the bar that is fixed penetrates in the through hole 5 of upper holder, adjusts the position, chucking; At last, in the through hole 5 of lower fixed frame 2, penetrate pressure pin 8 and fixing, make disk 9 upwards, adjust the expansion end of deformation measuring device 11, make its contact disk 9, finish installation.The test specimen to be measured 10 that deformation measuring device 11 will be installed afterwards is clamped on the testing machine and stretches, measure deformation result after, take off deformation measuring device 11, unclamp locating pin 7, can continue to stretch and measure maximum, force, off-test for to be tested 10.
