Background
Reinforcing steel bars (rebars) are steel materials for reinforced concrete and prestressed reinforced concrete, and have a circular cross section, and sometimes a square cross section with rounded corners. Comprises plain round steel bars, ribbed steel bars and twisted steel bars. The steel reinforcement is mainly subjected to tensile stress in the concrete. It is widely used in a variety of building structures, particularly large, heavy, light, thin-walled and high-rise building structures. The reinforcing steel bar can be better utilized by knowing relevant parameters of the reinforcing steel bar. The explanation of how to better and more accurately measure the reinforcing steel bars plays a very important role in the field of construction.
The parameters of the steel bar generally comprise length and diameter, and the elongation and the like are calculated through the parameters so as to confirm whether the mechanical property of the steel bar meets the requirements. Before a steel bar tensile test is carried out, marks with the interval of 10mm or 5mm need to be marked on the surface of a measured steel bar, and the current marking modes comprise manual marking of a steel saw blade, marking of a point marking machine, marking of a laser marking machine and the like. At present, the most common method is to use a hacksaw blade to mark, a worker holds the hacksaw blade, a steel bar is placed on a template, the hacksaw blade is used to mark notches every 5mm or 10mm, 45 to 50 marked lines need to be made on one steel bar, the consumed time is long, and the marking has no precision. And the dotting and marking instrument leaves marks on the surface of the steel bar by using a punch at intervals of impact, but the mode has high noise and low efficiency. The laser marking mode is a relatively new marking mode at present, can realize the high-precision marking of reinforcing steel bars, but needs high-power laser to mark slowly in order to ensure the marking effect, so that the marking speed is low, and the cost is high. And once the laser is not engraved to a sufficient depth due to the difference of the steel bars, surface pollution and the like, marks engraved by the laser disappear after the tensile test is usually performed, so that the test fails.
