The invention relates to a welding quality detection device for butt-joint steel bars. The welding quality detection device comprises a main marking post, an auxiliary marking post and at least two locking mechanisms; the upper part of the main marking post is provided with two connecting rods; the auxiliary marking post are slidably connected onto the two connecting rods; the auxiliary marking post is fixedly provided with two test pushing rods; the heads of the two test pushing rods are cone end heads and extend out by the same length; and each locking mechanism includes a locking ring and a locking rod, wherein the locking ring encloses the steel bars and the main marking post and is in detachable connection with the steel bars and the main marking post, and the locking rod is rotationally connected with one end of the locking ring, and the top portion of the locking rod abuts against the main marking post, so that the steel bars and the main marking post can be fixed to each other in the locking mechanism. With the welding quality detection device of the invention adopted, the bending angle and axis deviation of the joint of the butt-joint steel bars can be detected accurately, so that welding quality can be judged, and butt-joint steel bars of which the welding is unqualified can be reworked on site, and therefore, welding quality can be ensured, and the safety hidden troubles of engineering entities can be eliminated.
Description
technical field [0001] The invention relates to the field of construction, in particular to a welding quality detection device for butt jointed steel bars. Background technique [0002] In the prior art, the butt joint of steel bars has become one of the commonly used methods in the construction industry. Commonly used methods include flash butt welding of steel bars, electroslag pressure welding of steel bars, gas pressure welding of steel bars and so on. Taking electroslag pressure welding of steel bars as an example, the quality inspection of electroslag pressure welding joints is clearly stipulated in the industry standard JGJ18-2012 of the People's Republic of China (record number J253-2012): "The appearance quality inspection of electroslag pressure welding joints As a result, the following regulations should be met: the bending angle at the joint shall not be greater than 2°; the axis deviation at the joint shall not be greater than 1 mm". [0003] However, in the p...
