PURPOSE: A structure which does not require columns using a non-welding water tank is provided to reduce construction time and costs by using a non-welding water tank as a multiple-floor structure. CONSTITUTION: A structure which does not require columns using a non-welding water tank comprises a body part and multiple bottom plates(103). The body part forms multiple folding parts by lining a metal panel in a cylindrical shape and bending the bottom end of a top strip and the top end of a bottom strip. The bottom plates are installed inside the body part in a longitudinal direction to form multiple floors inside the body part.
