<p>The present invention relates to a profile connection structure to combine multiple profiles (1, 1′) having grooves (2, 2′) and fixing grooves (3, 3′) that comprises: a coupling bolt (10) having a thread (11) to be fixed to the fixing grooves (3) of the profile (1), a stopper (12) formed in the lower part of the thread (11) to interpose first contact parts (13), and a bolt head (15) formed in the lower part of the stopper (12) to interpose second contact parts (14); fixing parts (20) having a holding part (21) formed in the lower part and inserted in the grooves (2′) of the profile (1′) to be movable in the longitudinal direction of the groove (2′) in the state of being received in the grooves (2) of the profile (1) and a diagonal groove (22) penetrated in the side to be tapered; and coupling units (30) coupled to the diagonal grooves (22) of the fixing parts (20) to press the second contact parts (14) formed on the bolt head (15) and having a fixing bolt (31) to fix the grooves (2′) of the profile (1′) by vertically moving the holding part (21) through coupling. The present invention improves durability and safety by increasing the fixing force of the profiles and thus it can be used with heavy load caused by increased coupling strength when a frame required for the manufacture of shelves and others is formed. Also, the present invention is designed to couple the pair of profiles easily so that the convenience and workability of assembly and the productivity of complete assembly can be enhanced.</p> |
