The left and right side edge portions of the front and back plates 2 and 3 are folded back into a substantially U-shape, and bent front end side pieces 2a and 3a are formed at the front end of the side surface of the end portion of the door body 1. Is assembled in a state in which the bent front end side pieces 2a and 3a are in contact with each other so as to face each other, and between the front and back plates 2 and 3, an end portion located at the core material 4 and the left and right end portions A frame 5 is interposed. And both the bending front end side pieces 2a and 3a on the door end side are integrally connected by the connecting means of the present invention at a plurality of positions in the vertical direction in the concave portion of the concave groove end frame 5. In the first embodiment, a connecting tool (corresponding to the connecting means of the present invention) 6 is used as a connecting means, and both bent front end pieces 2a and 3a are provided at a pitch of 450 mm or less in the vertical direction and integrated. It is comprised so that it may be connected with.
[0007]
That is, the connecting tool 6 is bent into a substantially U shape using an elastic plate-shaped steel material to form a pair of fitting pieces 6a and 6b. Then, one fitting piece 6a is inserted from the end of the bent tip side piece 2a of one face plate (surface plate 2 in the present embodiment) on the opening side, and is attached to the side surface of the face plate with a fixing tool such as a rivet 6c. The other fitting piece 6b is formed with a stopper 6d that is bifurcated and recessed at the tip side, and the stopper 6d and the surface plate are bent. Between the front end side piece 2a, the bent front end side piece 3a of the back plate 3 is slid and inserted from the outside, so that both the bent front end side pieces 2a, 3a are inserted between the both fitting pieces 6a, 6b. It is fitted in a pinched form. Here, the stopper 6d is set so as to contact the back plate bent tip side piece 3a in a resilient manner, and is fitted to both bent tip side pieces 2a and 3a in a retaining manner.
[0008]
On the other hand, the bent tip side pieces 2a and 3a, which are the suspending side, are formed with notches 2b and 3b at the hinge 7 attachment site, between the end frame 5 and the double-sided plate 2 and the three end side surfaces. It is set so that the two bent front end side pieces 2a and 3a are integrally connected by fixing the hinge 7 with a rivet 7b or the like with the hinge spacer 7a interposed therebetween. Since the span where the hinge 7 is provided is longer than the connection span by the connecting tool 6 on the door end side, a connecting spacer 7c is interposed at an appropriate position between the hinges 7 and connected to the front and back plates 2, 3 It is set so that the two bent leading end side pieces 2a and 3a are integrally connected to each other by being fastened to the side surface of the end portion by a rivet or the like 7b. Here, when the spacers 7a and 7c are fastened to the rivets 7b, the holes 2c and 3c drilled on the side faces of the rivets are dished by punching so that the rivet heads do not protrude from the side faces of the front and back plates After that, rivets are fastened. Further, the connecting spacer 7d shown in FIG. 9 is formed in a substantially U-shaped cross section unlike the solid connecting spacer 7c shown in FIGS. 7 and 8, but in this case, the connecting spacer 7d Since a gap is formed between the end frame 5 and the end frame 5, it is possible to fix the rivets to the end side surfaces of the front and back plates 2 and 3, and there is no need to drill the end frame 5.
