Attach the four pieces to the inside of the intersection corners C and D. Next, select the inner sides of the intersecting corners C and D, which are diagonally opposite each other in FIG. Hooks 17a at both ends of the tensioning device B are hooked to the hooks 17a at both ends of the tensioning device B to 12, the tensioning device B is engaged between the inner sides C and D of the intersecting corners on the diagonal line, and the tensioning device B is tensioned. Stretch the tension body B between the inner sides of the intersecting corners C and D, and then tighten each male screw 17 between the two.
By rotating the turnbuckle 17c screwed into b, the two connecting rods 17 are brought closer to each other, and the first tensioning tool B is gradually tightened between the support 1 and the vertical mounting frame 3, and then they are crossed again. A tension tool B is also stretched between the remaining one diagonally located inner side of the intersecting corners C and D via both corner fittings 10, and is screwed into the male threaded portion 17b of the connecting rod 17. Rotate the turnbuckle 17c, bring the two connecting rods 17 closer together, and gradually tighten the second tensioning tool B between another support 1 and the vertical mounting frame 3, and check the distortion of the square of the frame. is adjusted to eliminate distortion in the shape of the balcony A after assembly, and at the same time, the four corner fittings 10 and the two intersecting tensioning devices B are used to strengthen the balcony frame against horizontal shaking. This completes the assembly of balcony A and its attachment to the building frame.

(Effects of the invention) Since the present invention has a configuration consisting of the structure and operation clarified in the above embodiment, as a direct effect, the corner fitting 10, which is the main part of the configuration of the present invention, can be replaced with the front spar 2. By placing it inside the four intersecting corners formed by the end beam 4 and the end beam 4 and the joist hook 8, the role of the flint beam is to maintain a right angle angle by using the intersecting corners as a combination angle. It can take on three roles: supporting the outer front and rear ends of the horizontal decking material placed on the top surface, and locking the hooks 17a at both ends of the tensioning device B. Not only the length improves the strength of the square part, but also
The crossed tensioning devices B also play the role of horizontal braces, increasing the rigidity of the frame.The bolt mounting grooves 8b, 4b, and 2b are also used for the joist hook 8 and the gable beam during forming, respectively. 4. Since it can be extended integrally with the front girder 2 by extrusion molding, there is no increase in the production process, and,
Since the nut 15 is screwed in with the bolt head 14a of the fixing bolt 14 locked in the bolt mounting groove consisting of a lip groove, the bolt is inserted into the flange type mounting edge as is generally done. The head of the bolt inserted through the hole is supported with the tip of a finger, and there is no need to worry about the trouble of screwing the nut on and the risk of the bolt falling off. Since the rising pieces 11 are set upright on two sides sandwiching each of the joists, and these rising pieces 11 are in contact with or fixed to the inner sides C and D of the four intersecting corners, due to long-term use, The left and right end girders 4 and front beams 2 do not easily displace in the horizontal plane, and the frame of the metal balcony can be firmly held for a long period of time.
