Abstract
The object of this invention is to provide a reinforcing bar coupling used to easily, simply, quickly and mechanically butt-joint two reinforcing bars to each other for use in reinforced concrete construction. The reinforcing bar coupling consists of a cylindrical sleeve (2) axially receiving two reinforcing bars (1) through two inlets (20), with an uneven interior surface (22) formed in the sleeve (2) to correspond to the ribs (11) formed around the external surface of the bars (1). A plurality of wedges (4) are set in the gap between the bars (1) and the sleeve (2). The internal surface of the sleeve (2) and the external surface of the bars (1) with the wedges (4) are radially compressed to butt-joint the two bars (1) by the coupling.
Claims14
A reinforcing bar coupling, comprising:
- a cylindrical sleeve having a cross sectional area sufficient to accommodate two reinforcing bars entered through inlets at opposite ends thereof, and which is provided at a part of its inner surface with an uneven surface corresponding to a n outer ribbed surface of the reinforcing bars;
- wedge means adapted to be fitted between the sleeve and the reinforcing bars to apply radial force to them, thereby achieving butt-jointing of the two reinforcing bars.
