The invention relates to the technical field of building material detection equipment, and discloses a steel bar strength detector for construction engineering quality supervision, which includes a detection frame, a bottom groove, a wire and an instrument host. A fixed ring is fixedly installed on the top of the inner cavity, a driven gear is movably sleeved on the bottom of the fixed ring, and a driving gear is engaged with the outer surface of the driven gear. In the steel bar strength tester for construction engineering quality supervision, the extension cylinder can move up and down on the outer surface of the longitudinal rod, and the fixed cylinder can move left and right on the outer surface of the adjustment rod. The fixing of the fixed cylinder, moving the fixed cylinder up and down can adjust the extension cylinder to move up and down, and people can adjust the arc size formed by the bottom ends of the three extension cylinders by adjusting the extension cylinder. When the steel bar bends, it will bend along the bottom of the extension cylinder. Therefore, the tester can test the bending resistance of steel bars under different bending angles.
Description
technical field [0001] The invention relates to the technical field of building material testing equipment, in particular to a steel bar strength testing instrument for quality supervision of construction projects. Background technique [0002] In building construction, it is necessary to supervise and check each construction step. The checking of building materials is an important part of the quality inspection process of building construction. For the inspection of some building materials, such as sand, formwork, etc., it is enough to observe and touch. For materials such as steel bars and PE pipes, relevant instruments are required for testing. [0003] In the construction site, people usually use the steel bar strength tester to test the flexural strength of the steel bar. The existing tester is usually composed of a testing frame and a testing instrument host. People place the steel bar to be tested inside the testing bracket, and then shake it. The rocker moves the pr...
