<p>The present invention relates to a coupling device for a deformed bar capable of firmly coupling ends of deformed bars. The coupling device for a deformed bar includes a cylindrical housing having a constant diameter and formed with a plurality of through-holes and fixing holes on the outer circumference thereof; a pair of arc-shaped pressing members inserted into the housing and having flanges at upper and lower portions and a plurality of fixing grooves on the outer surface; an arc-shaped elastic pad coupled to the inner surface of the pressing member; a pair of arc-shaped spacers inserted between the pressing members and having flanges at upper and lower portions and a protrusions protruding from the outer surface; and a fixing member fixed to the fixing hole by a screw, with an end coming into contact with the fixing groove. The deformed bars are inserted and fixed between the pressing members and the spacers from the top and the bottom. It is possible to reduce machining times and expenses and distribution costs because a threaded portion is not machined on the end of the deformed bar. Since the deformed bars are provided in a semi-assembled state, the time for assembling components is reduced, and any component may not be missed due to carelessness, when assembling the components, thereby minimizing a waste element. Experts or unskilled labors can easily carry out the coupling work of the deformed bars, thereby reducing the construction costs and the working time.</p> |
