<p>The present invention relates to a stanchion, formed of a ground plate supporting the ground to enable a plurality of pipes to be connected; and a vertical rod vertically coupled to the ground plate, which further includes a U-bolt member formed in a U-shape at the vertical rod, and formed of a holder having a screw thread formed at both ends toward an inner portion; a holding plate having a holding hole formed to be inserted into the both ends of the holder, and having a serrated pressing groove formed along the circumference of the holding hole to have a rear surface coming in contact with the vertical rod; and a bolt fastened to the screw thread, and having a serrated fastening groove formed at a rear portion, such that the pressing groove and the fastening groove are alternately disposed when the holding plate is pressed by the bolt to increase the fastening strength, thereby preventing a falling accident by not allowing an electric panel to easily be released from the stanchion, forming a folding structure to prevent a worker from being injured by a short circuit in the electric panel, and additionally functioning as a telegraph pole for pedestrians at night.</p> |
