PURPOSE:To eliminate any process of assembling a frame at site, position a landing easily, and save labor for construction work at site. CONSTITUTION:A frame 2 for supporting a landing comprises a stereoframe 2a made by a combination of multiple frame members 4. The adjacent frame members 4 of the stereoframe 2a are fixed to each other using angles 5 with a fixing part at their both ends. Then a self-standable unit stereoframe 2a is formed. The top 5a of the angles 5 is projected above the upper edge of the stereoframe 2a to enable it to come into contact with the lower part of the landing. Thus the landing can be positioned easily using the upper part 5a of the angles 5. |
