PROBLEM TO BE SOLVED: To prevent the locking of vertical and horizontal reinforcements from being put into an imperfect state by vibrations of an earthquake etc., and to prevent the vertical and horizontal reinforcements from being put into a distorted state when the vertical and horizontal reinforcements are locked to one another, in the case of a conventional cage. SOLUTION: In this assembly type cage, at least three circular arc surface-shaped assemblies are formed by vertically and horizontally assembling the linear vertical reinforcements with the arc-shaped horizontal reinforcements; a hook part, which is engaged with the vertical reinforcement at the other end of the adjacent assembly, is formed at one end of the horizontal reinforcement which constitutes each of the assemblies; the assembly is made cylindrical by engaging each of the hook parts with the vertical reinforcement; and after that, a plurality of loop reinforcements are fixed by being arranged on a cylindrical inside. The vertical reinforcements are joined by welding respective points which are intersected with the two horizontal reinforcements arranged to the upper or lower ends of the vertical reinforcements, and locked by binding respective points which are intersected with the other horizontal reinforcements, so that the locking of the vertical and horizontal reinforcements can be prevented from being put into the imperfect state by the vibrations of the earthquake etc., and so that the vertical and horizontal reinforcements can be prevented from being put into the distorted state when the vertical and horizontal reinforcements are locked to one another.
