Construction Status and Improvement Plan for Coupler Splicing Joints of Rebar

In order to achieve structural performance such as rebar clear spacing in the reinforced concrete structure construction, coupler splicing joints are becoming common. To confirm the performance of rebar splicing joints, quality verification is being carried out through coupler specimen tests. However, it can be said that the required performance is reached only when the actual construction in the field is constructed under the same conditions as the coupler splicing joint specimen. Therefore, the problems and solutions of the coupler splicing joint construction of the actual field was investigated in this study.
