Detailed Description
The utility model discloses a base 9, its characterized in that: a triangular groove 10 is arranged in the middle of the base 9, and a scale 6 and a slide way 5 are arranged on two sides of the triangular groove 10; a cursor frame 8 is arranged above the base 9, and the bottom of the cursor frame 8 is provided with a sliding shoe 1 matched with the sliding way 5; the top of the vernier frame 8 is provided with a positioning pointer 4 corresponding to the central axis of the triangular groove 10 through threads, and the bottom of the vernier frame 8 is provided with a reading pointer 2 corresponding to the scale 6 and the positioning pointer 4.
As a preferred scheme of the present invention, two cursor frames 8 are disposed on the base 9.
As another preferable aspect of the present invention, the precision of the scale 6 is set to 0.1 mm.
As a third preferred embodiment of the present invention, the cursor frame 8 is provided with a magnifying glass 3 corresponding to the reading pointer 2.
As a fourth preferred aspect of the present invention, the reading pointer 2 is parallel to the scale 6 and contacts with the surface of the scale 6.
The base 9 both ends are provided with shutoff 11, also are provided with triangle recess 10 on the shutoff 11, do not set up slide 5. The longer reinforcing steel bar test piece 7 is convenient to fix, and meanwhile, the cursor frame 8 can be prevented from sliding out of the end part of the base 9.
The included angles between the two inclined planes of the triangular groove 10 and the vertical plane are both 45 degrees.
The utility model discloses an implementation: step one, will the utility model discloses on the workstation is arranged in to the tie, adjust the location pointer 4 to suitable height on two cursor frames 8, be convenient for lay reinforcing bar test piece 7.
And step two, the steel bar test piece 7 with the marked distance is flatly placed in the triangular groove 10, and the test piece is adjusted to a proper position along the triangular groove 10.
Moving the left cursor frame 8 to the leftmost punching point or the marking line of the gauge length of the steel bar test piece 7, rotating the positioning pointer 4, accurately aligning the lower end of the positioning pointer 4 to the leftmost punching point, and reading the reading a of the scale 6 on the left side of the reading pointer 2 through the magnifier 30Accurate to 0.1 mm; moving the right-side cursor frame 8 to the rightmost punching point or the marking line of the gauge length of the steel bar test piece 7, rotating the positioning pointer 4, accurately aligning the lower end of the pointer to the rightmost punching point, and reading the reading b of the scale 6 on the left side of the reading pointer 2 through the magnifier 30And when the accuracy is 0.1mm, the gauge length L of the steel bar test piece 7 before stretching0=b0-a0。
