AI Technical Summary

Technical Problem

In the prior art, there is a large error in measuring the bending angle of the steel bar, which is difficult to ensure the accuracy of the measurement, especially when workers use homemade protractor tools in small factories.

Method used

A measuring tool including a protractor, a fixed ruler, a movable ruler, a locking assembly and a positioning device is designed. The movable ruler is freely rotated by unlocking the locking assembly, fixed to the steel bar with the positioning device, and the actual bending angle can be read out in combination with the protractor, and the difference between the preset bending angle and the actual bending angle can be measured through the auxiliary ruler for adjustment.

Benefits of technology

It improves the accuracy of the bending angle measurement of steel bars, the structure is simple and easy to operate, and is not affected by the proficiency of workers, and can meet construction requirements.

Abstract

The utility model relates to the technical field of measuring tools, in particular to a measuring tool for detecting the bending angle of a floor reinforcing steel bar. Comprising a protractor, a fixed ruler fixedly connected to one side of the protractor and extending in the radial direction of the protractor, a movable ruler rotationally connected to the circle center of the protractor and extending in the radial direction of the protractor, and a locking assembly arranged at the circle center of the protractor and used for jointly locking or unlocking the protractor and the movable ruler. And the positioning devices are respectively arranged on the back surfaces of the fixed ruler and the movable ruler and can be fixed on a reinforcing steel bar. The measuring tool is simple in structure, convenient to operate, small in starting difficulty and not prone to being influenced by the proficiency of workers, and the accuracy of steel bar bending angle measurement is greatly improved.
