<p>The present invention relates to a safety handrail installed on steel beams to prevent a worker from falling during a beam work in the construction site and, more specifically, to technology for fastening a main panel bracket perpendicularly to an auxiliary panel bracket which is directly inserted into a steel beam, thereby preventing a safety handrail from being deformed due to a repulsive force of the steel beam when the safety handrail is coupled to the steel beam by using bolts, and simply dismantling the safety handrail from the steel beam if necessary. According to the present invention, the auxiliary panel bracket is inserted to be coupled to the main panel bracket to make a right angle with each other such that the steel beam can be fitted to be fixed to the auxiliary panel bracket and the main panel bracket, thereby preventing the safety handrail from being deformed due to a repulsive force of the steel beam and strongly fastening the safety handrail to the steel beam when the safety handrail is fixed to the steel beam by using the bolts, wherein the auxiliary panel bracket is bent in two stages to have aΠ-shaped section, and the main panel bracket is bent in two stages to have aΠ-shaped section.</p> |
