In this study, coupler on the safety of meeting the requirements and construction and economy to satisfy the number of parts to minimize an LK-DK coupler has been developed, affordability existing reinforcing bar joint, welded joint, mechanical joints, compared with a favorable one to the understanding, and also facilitate the construction and logistics, etc. I've found that there is no additional pay because the amount of product performance through the tensile test after test, if commercialization is expected to be greater ramifications.
