건설용 철근 20~70Φ급 자동 철근 결속기의 설계·제작에 대한 고찰 = Study on the Design and Manufacture of Auto-binding Apparatus for the Construction of Reinforcing Bar of 20~70Φ Range

다국어 초록 (Multilingual Abstract)

In general, the method of supplying the wire of auto-binding apparatus for reinforcing bar used in construction sites are often poor and supplies by using the hall way, the head of the thick binder is often an obstacle for interference when bind the reinforcing bar. In this paper, we proposed a new auto-binding apparatus for reinforcing bar by improving the existing bond issues that they work for the common descriptor. The auto-binding apparatus for reinforcing bar is easy to carry because it is designed with a pistol grip shape. It also has the advantage to increase the productivity because it is easy binding of the reinforcing bar itself, rather than binding operation by a person. It was designed and produced by adding a multi-functional to automatically bond the reinforcing rod of $20{\sim}70{\Phi}$ range. We carried out the performance evaluation tests, such as binding strength, binding time, binding range, body weight, wire cutting unit wear, binding malfunction test in order to compare and validate domestic and foreign technical level of the performance of the developed auto-binding apparatus for reinforcing bar. As a result, it was confirmed that the development of each item is reached.
