MECHANICAL JOINT FOR REINFORCEMENT

PROBLEM TO BE SOLVED: To avoid a decrease in the shear strength, buckling strength, etc. of a reinforced concrete support etc. SOLUTION: A connecting bolt 2 is provided with a central portion 21 with a predetermined axial length, so that a gap smaller than the outside diameter of a tubular member can be surely secured between the pair of tubular members 1. Thus, when a hoop 4 abuts on the tubular member 1, an increase in the winding diameter of the hoop can be suppressed by winding the hoop around the gap. This makes it unnecessary to decrease the winding diameter of the hoop 4 so as to secure the covering depth of concrete, and can prevent the decrease of the shear strength and buckling strength of the reinforced concrete support, a beam, etc. COPYRIGHT: (C)2009,JPO&INPIT
