PROBLEM TO BE SOLVED: To get a frame assembly which is high in volume efficiency and besides can be assembled simply and efficiently and is high in sticking tendency and has rigidity, by enabling frame material and an angle member to be stocked and carried in an unassembled condition and assembled on the site. SOLUTION: In frame material 2 which are made by forming peripheral wall parts 6a and 6b and flange parts 7a, 7b, 8a, and 8b in one united long material and bending the first and second members 9a and 9b at a specified angle and putting the corners together thereby making an angle between themselves, angle members 3 where first and second superposition members 16a and 16b are made integrally are superposed on the flange parts 7a, 7b, 8a, and 8b in the vicinity of the angles 12, and the engaging parts consisting of the projections 17a and 17b provided at one hand between the flange parts 7a, 7b, 8a, and 8b and the first and second superposition pieces 16a and 16b and the recesses 18a and 18b provided at the other hand are engaged with each other thereby being positioned, and the flange parts 7a, 7b, 8a, and 8b and the first superposition pieces 17a and 17b an the second superposition pieces 18a and 18b are fixed at fixing parts 5. |
