PROBLEM TO BE SOLVED: To provide a reinforcement intersection fastener capable of increasing the fastening force of a reinforcement intersection because one reinforcement engaging to an engaging groove of a plate has a strong force to prevent another reinforcement from rotating in a circumferential direction along with both U bolts.SOLUTION: A reinforcement intersection fastener comprises: a plate 1, which has an engaging groove 11 butting and engaging to a first reinforcement 4 at an intersection between the first reinforcement 4 and a second reinforcement 5; two U bolts 2, 2; and nuts 3, 3. The plate 1 comprises: two bolt insertion holes 12 along the engaging groove 11 on both ends of the plate; and irregularities 21a, 21a along a circumferential direction at a part of U-shaped bent parts 21, 21 of both U bolts 2, 2 to which at least the second reinforcement 5 butts. The intersection between both reinforcements 4, 5 is strongly fastened and fixed between two U bolts 2 and the plate 1 by inserting two U bolts 2, 2 from the second reinforcement 5 side into the insertion hole 12 of the plate 1 and screwing nuts 3 to the U bolts to fasten.SELECTED DRAWING: Figure 5 |
