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
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.
