<p>The present invention relates to a connecting groove which connects a vertical profile (1) having concave grooves (2, 2′), protrusions (3, 3′), and a horizontal profile (1′); and comprises: a main body (10) mounted on the concave grooves (2) of the vertical profile (1), having a vertical hole (12) communicated with a pressurizing groove (11) on an upper portion to show elasticity by being separately formed on both sides; a fixing nut (20) having a coupling groove (21) perpendicularly corresponding to the pressurizing groove (11) and the vertical hole (12) by being inserted into the concave groove (2′) of the horizontal profile; and a pressurizing bolt (30) mutually fixating the vertical profile (1) and the horizontal profile (1′) by being coupled on the coupling groove (21) of the fixing nut (20). Therefore, the present invention can be used regardless of a heavy load by increasing a coupling intensity while maintaining the availability for reconstruction in case of when changing the purpose of a shelf or a frame, and significantly reducing the possibilities of an accident from occurring.</p> |
