Description

Technical Field [0001] The present invention relates to a reinforcing connection device,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing bar fastening device, and more particularly, to a reinforcing bar fastening device that can easily fasten each reinforcing bar constituting a reinforcing concrete structure used in a building site to a coupler.

Generally, a large amount of reinforcing steel is buried in a reinforced concrete structure to reinforce durability, vibration resistance and tensile strength of a concrete structure which is weak in tensile strength.

      That is, a large amount of reinforcing bars having a certain length is arranged in a vertical and horizontal direction and installed in a net shape, and concrete is then installed to construct a reinforced concrete structure.

      Meanwhile, in recent years, the length of the reinforcing bars buried in the concrete has been prolonged proportionally due to the enlargement of the reinforced concrete structures and the high-rise buildings due to the trend of high-rise buildings.

      However, since the reinforcing bars are provided to have a certain length and have a limited dimension, it is essential to interconnect reinforcing bars of a certain length in order to bury the reinforcing bars according to the height of the structure.

      Conventionally, in the connecting work of the reinforcing bars, a pair of reinforcing bars are overlapped and then bundled or welded by hand is mainly used. However, the above-mentioned methods have a problem in that workability is lowered and durability and stability There was a falling problem.

      In order to overcome such a problem, a method of extending the length of a reinforcing bar has been mainly used, in which a substantially tubular coupler having threads formed on its inner peripheral surface is used.

      That is, a thread is formed on the entire body or the end side of the reinforcing bar, and a pair of reinforcing bars are screwed to both sides of the coupler, so that the pair of reinforcing bars can be firmly and integrally connected through the coupler do.

      In the connecting operation of the reinforcing bars using the coupler as described above, a plurality of reinforcing bars are conveyed by a crane provided with a jig for conveying the reinforcing bars, depending on the characteristics of the reinforcing bars having a high weight, The connection operation is performed.

      However, since the connection work of the reinforcing bars using the conventional coupler is performed by directly connecting the reinforcing bars transferred by the crane to the pre-installed reinforcing bars through the respective couplers, the crane must be always accompanied with the work, There is a problem that the utilization efficiency is remarkably lowered.
