Abstract
The utility model discloses a measuring tool of per meter crookedness of straight bar reinforcing bar, including the body of rod, slide on the right side portion of the body of rod and be setting up a buckle, slide on the buckle and be setting up a spring pointer, setting up the distance scale on the buckle, the pointer with the body of rod mutually perpendicular. The utility model discloses an adjustment can measure per meter crookedness of straight bar reinforcing bar any position about the buckle, has improved the work efficiency of inspection job site. Through the measurement of the bending degree of the straight reinforcing steel bar, the straight reinforcing steel bar with unqualified bending degree per meter is completely stopped from flowing out for sale, and quality objection is avoided.
Description
Technical Field
The utility model relates to a measuring tool of per meter crookedness of straight bar reinforcing bar.
Background
According to the specification of 6.5 bending degree and end part in the national standard 'hot-rolled ribbed steel bar of the second part of steel for reinforced concrete' > GB 1499.2-2018; the curvature of the straight steel bar does not influence normal use, the curvature per meter is not more than 4mm, and the local deformation does not influence use. The standard does not provide a method for measuring the bending degree of the straight steel bar per meter, and the straight steel bar with the bending degree of not more than 4mm per meter does not influence the use according to the national standard upper limit. On the inspection site, the degree of bending of each meter of the straight steel bar is judged to meet the national standard (the degree of bending of each meter is not more than 4 mm). At present, a special tool for directly measuring the degree of curvature of each meter of straight reinforcing steel bars does not exist, and the measurement of the degree of curvature of each meter of straight reinforcing steel bars always troubles the production inspection field. The bending of the straight reinforcing bar per meter must be quantitatively measured. The large deformation (large bending) of the straight steel bar can be directly judged by naked eyes, and the detection and judgment can be carried out by 6.5 in the national standard 'hot-rolled ribbed steel bar of the second part of steel for reinforced concrete' GB 1499.2-2018. However, the bending of a straight bar with a small deformation (about 4 mm) cannot be directly determined by naked eyes.
Disclosure of Invention
An object of the utility model is to provide a measuring tool of per meter crookedness of straight bar reinforcing bar can measure the crookedness of per meter any position of straight bar reinforcing bar respectively through the adjustment buckle at excellent line production site, carries out the quality of straight bar reinforcing bar crookedness to the accuse.
Realize the measuring tool of the per meter crookedness of straight bar reinforcing bar of above-mentioned purpose, including the body of rod, the right side portion of the body of rod is gone up to slide and is being set up a buckle, and the slip is setting up a spring pointer on the buckle, is setting up the distance scale on the buckle, the pointer with the body of rod mutually perpendicular.
The buckle of the straight bar steel bar bending degree measuring tool can move left and right, and the pointer on the buckle can contract up and down and display the numerical value of each meter of bending degree. The both ends with this instrument are taken respectively in one side of straight bar reinforcing bar when measuring straight bar reinforcing bar per meter crookedness, remove about the buckle can measure per meter crookedness of any place in this scope, and reading when perpendicular instrument is pressed pointer and straight bar reinforcing bar contact just can measure per meter crookedness of this position straight bar reinforcing bar to reach the mesh of straight bar reinforcing bar crookedness survey. The utility model discloses an adjustment can measure per meter crookedness of straight bar reinforcing bar any position about the buckle, has improved the work efficiency of inspection job site. Through the measurement of the bending degree of the straight reinforcing steel bar, the straight reinforcing steel bar with unqualified bending degree per meter is completely stopped from flowing out for sale, and quality objection is avoided.
During the use, take the both ends of per meter crookedness measuring tool of straight bar reinforcing bar in one side of straight bar reinforcing bar respectively, remove about the buckle and can measure per meter crookedness of any place in this within range, reading when perpendicular instrument is pressed pointer and straight bar reinforcing bar contact just can measure per meter crookedness of this position straight bar reinforcing bar, carries out the pointer reading, if less than or equal to 4mm then per meter crookedness is qualified, otherwise is unqualified.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic view of the structure of the present invention.
Detailed Description
The utility model provides a measuring tool of per meter crookedness of straight bar reinforcing bar, as shown in figure 1, including the body of rod 1, slide on the right side portion of the body of rod 1 and be setting up a buckle 2, slide on buckle 2 and be setting up a spring pointer 3, be setting up the distance scale on buckle 2, pointer 3 with the body of rod 1 mutually perpendicular.
Claims (1)
