Abstract
The utility model discloses a rebar bending resistance tester which comprises a test box, wherein two rebar positioning rollers are arranged at one end of the test box; a telescopic driver is arranged at the other end of the test box and provided with a drive rod; the drive rod is vertical to the connection direction of the two rebar positioning rollers and points to the space between the two rebar positioning rollers; a dial is arranged between the two rebar positioning rollers on the test box; and scribed lines are arranged on the dial. In the test process of the rebar bending resistance tester, the bending degree of a rebar sample can be determined by observing the scribed lines corresponding to the rebar sample on the dial, and then the telescopic driver is controlled by a manual control valve, thus the rebar bending resistance tester is easy for controlling the bending degree of the rebar sample in operation and guarantees the accuracy of the test result.
Description
Technical field
The utility model relates to a kind of reinforcing bar proving installation, more specifically is a kind of reinforcing bar beam test instrument, belongs to the test apparatus technical field.
Background technology
Anti-bending strength is one of leading indicator of steel bar quality, all will carry out the beam test of reinforcing bar in some reinforcing bar production units, reinforcing bar applying unit, reinforcing bar detection unit etc. for this reason.Existing a kind of reinforcing bar beam test instrument comprises chamber, the other end that is provided with in two reinforcing bar registration rollers, the chamber at the end in the chamber is provided with telescopic drive, telescopic drive has driving stem, the line perpendicular direction of driving stem and two reinforcing bar registration rollers, and driving stem points between two reinforcing bar registration rollers.During above-mentioned reinforcing bar beam test instrument test, reinforcing bar sample is placed on two reinforcing bar registration rollers towards a side of telescopic drive, open telescopic drive, the end of the driving stem of telescopic drive withstands on the reinforcing bar sample, make bar bending arrive certain degree, to reinforcing bar sample carry out repeatedly bending with stretch, until reinforcing bar sample fracture, draw the anti-bending strength of reinforcing bar sample from number of bends.But because above-mentioned reinforcing bar beam test instrument is in process of the test, it is the degree of crook by direct observation reinforcing bar sample, then control telescopic drive by manually operated control valve, therefore the degree of crook of reinforcing bar sample is difficult to control in operation, often easily make reinforcing bar sample curved transitions or crooked not in place, affect test findings.
The utility model content
For above-mentioned situation, the degree of crook that the problem that the utility model quasi-solution is determined provides a kind of reinforcing bar sample in operation holds manageable reinforcing bar beam test instrument, with warranty test result's accuracy.
For addressing the above problem, the utility model has adopted following technical scheme: a kind of reinforcing bar beam test instrument, it comprises chamber, the other end that a end in the described chamber is provided with in two reinforcing bar registration rollers, the chamber is provided with telescopic drive, described telescopic drive has driving stem, the line perpendicular direction of described driving stem and two reinforcing bar registration rollers, and driving stem points between two reinforcing bar registration rollers, in the described chamber, be provided with index dial between two reinforcing bar registration rollers, has groove on the described index dial.
Described index dial is semicircle, and the groove on the described index dial is semicircular radial direction.
Adopt said structure, reinforcing bar beam test instrument of the present utility model is owing in the chamber, be provided with index dial between two reinforcing bar registration rollers, having groove on the described index dial.Like this, reinforcing bar beam test instrument is in process of the test, can be by observing the groove of reinforcing bar sample correspondence on index dial, determine the degree of crook of reinforcing bar sample, then control telescopic drive by manually operated control valve, therefore the degree of crook of reinforcing bar sample holds manageable reinforcing bar beam test instrument in operation, has guaranteed the accuracy of test findings.
Description of drawings
Fig. 1 is the structural representation of the utility model reinforcing bar beam test instrument;
Fig. 2 overlooks the structural representation of direction when being the test of reinforcing bar beam test instrument.
Among the figure: 1-chamber, 2-reinforcing bar registration roller, 3-telescopic drive, 4-driving stem, 5-index dial, 6-groove, 7-reinforcing bar sample.
Embodiment
As shown in Figure 1 and Figure 2, reinforcing bar beam test instrument of the present utility model, it comprises chamber 1, the other end that a end in the described chamber 1 is provided with in two reinforcing bar registration rollers 2, the chamber is provided with telescopic drive 3, described telescopic drive 3 has driving stem 4, the line perpendicular direction of described driving stem 4 and two reinforcing bar registration rollers 2, and driving stem 4 points between two reinforcing bar registration rollers 2.The structure of the reinforcing bar beam test instrument of said structure and prior art is similar, therefore no longer launches.
The characteristics of reinforcing bar beam test instrument of the present utility model are: in the described chamber 1, be provided with index dial 5 between two reinforcing bar registration rollers 2, have groove 6 on the described index dial 5.The setting of described index dial 5 can have reference by the degree of crook of reinforcing bar sample 7 when beam test.Described index dial 5 is semicircle, and the groove 6 on the described index dial 5 is semicircular radial direction.Certainly, according to actual conditions, described index dial 5 can also be made into other shape, here enumerates no longer one by one.
