The utility model relates to the technical field of ladder treads, in particular to a shaped steel
tread of a ladder for people to
climb up and down on a construction site, which comprises an upper caliper, a drain hole and a fixture block, and has the beneficial effects that the upper caliper is arranged, and a detachable pedal is connected with a main rod through the upper caliper and the lower caliper, so that the steel
tread is convenient and quick to install on the construction site, and the construction efficiency is improved. A worker can carry a plurality of parts, installation is convenient, the turnover
utilization rate of materials is improved, drainage is convenient in rainy days through the arrangement of the drainage holes, the antiskid coefficient of the pedal is increased through the design of the antiskid strips, the clamping blocks are arranged on the inner sides of the upper
calipers and connected with the clamping grooves in the outer sides of the main rods in a clamped mode, and the pedal and the main rods are prevented from sliding relative to each other when the pedal bears loads; the inner side of the lower caliper is provided with the
insertion rod, and the
insertion rod is connected with the connecting rod in an
insertion manner, so that when the pedal bears load, part of force acts on the insertion rod, the pedal is prevented from bearing
overweight, the nut and the screw rod are prevented from loosening, and the safety performance of the
crawling ladder is enhanced.
