Acoplador de barra de refuerzo con el que se conecta y ajusta una barra de refuerzo, que comprende una tapa de acoplador hueca con un extremo exterior abierto por el cual se va a insertar dicha barra, una rosca hembra en espiral que tiene un hueco perforado, un resorte de sujecion con forma de espiral que corresponde a la rosca hembra el cual esta hecho de un material que puede torcerse y cambiar en diametro bajo una fuerza externa y puede reestablecerse elasticamente, y se ajusta y fija a la rosca hembra

摘要

A reinforcement bar coupler, in which a female thread having an inclined taper plane is formed on the inner surface of a coupler cap, and a clamping spring is inserted into and fastened to the female thread. When a reinforcement bar is inserted into the clamping spring, the clamping spring is closely abutted to the bottom of the female thread and is increased in diameter so that the reinforcement bar slips. With the reinforcement bar being inserted, when an external force is applied in the direction opposite to the direction in which the reinforcement bar is inserted, the clamping spring moves along the inclined taper plane and is decreased in diameter, thereby holding the reinforcement bar. It is therefore possible to easily connect and couple the reinforcement bar with one touch based on a change in the diameter of the clamping spring using a relatively simple configuration.
