<p>The present invention relates to an iron bar coupling device and, more specifically, to an iron bar coupling device which enables both end portions of respective iron bars, which are used for building reinforced concrete structures and are to be coupled with each other, to be easily inserted into and coupled with a connector, and prevents the iron rod from being loosed from the connector, even when an external vibration occurs, by enabling both end portions of the connector to fasten around an outer periphery of the iron bar. The iron bar coupling device couples two iron bars having male screw portions formed on an outer periphery thereof with each other by a connecting means, and the connecting means includes a connecting unit and a fastening unit. The connecting unit forms a connecting pipe member, whose both sides are opened and which has an open portion with a female screw portion formed on the inner periphery thereof, and includes a coupling pipe member, which is extended toward both ends of the connecting pipe member from a center point of the open portion and is formed to be deflected from a deflection center point deflected toward one side. The fastening unit forms a fastening pipe member having an open portion with the same center point as the open portion of the connecting unit. The fastening unit is composed of an insertion groove unit having the same center point as the deflection center point of the coupling pipe member, such that the coupling pipe member is inserted from the rear surface of the fastening pipe member into an inner portion of the fastening pipe member.</p> |
