  The upper end portion of the leaf spring 11 is fastened to a bolt 15 that is horizontally mounted between the upper end portions of the left and right side frames 8 a and 8 a of the operation lever 8, and the lower end portion is provided on the left and right side plates 7 b and 7 b of the fixed frame 7. The bolts 14 are inserted into the long holes 13 and 13 and are fixed to the bolts 14 that slide up and down. In this embodiment, a leaf spring is used, but a linear spring may be used.

  4 (a) and 4 (b), the operation lever 8 is held in an upright state by a curved leaf spring 11, and the gripping metal 9 is locked at a position where the side bent portion 1b of the scaffold plate 1 is gripped. Indicates the state. When the operating lever 8 is gripped by the handle 8o and rotated to the near side as shown in FIG. 5 (a) from this locked state, the locked state is released, and the leaf spring 11 interlocked with the operating lever 8 releases the lock. When the bolt 14 is pushed downward, the slide plate 9a of the gripping metal 9 slides downward, and the operating lever 8 is further rotated downward, so that the slide plate 9a slides as shown in FIG. 5 (b). And the space between the lower surface of the baseboard body 5 and the tip portion (contact piece) 10o of the hook portion 10 is maximized, and can be fitted to the side edge portion 1b of the scaffold plate 1 Become. As shown in FIGS. 4 and 5, a projecting ridge 5 o projects from the lower surface of the lower flange 5 c of the baseboard body 5, and this projecting ridge 5 o is attached to the scaffold plate 1. It is sometimes engaged with a concave strip 1o formed on the top surface 1a of the scaffolding plate 1 (see FIG. 6).

  6 (a) to 6 (d) show the procedure for attaching the skirting board body 5 to the scaffolding board 1 by the one-touch lock fitting 6 described above. First, as shown in FIG. 6 (a), the operation of the one-touch lock fitting 6 is performed. The lever 8 is gripped by a grip 8o at its upper end and rotated downward to slide the slide plate 9a of the gripping metal 9 through the leaf spring 11 to the lower limit position of the slide range. From the state where the space between the hook portion 10 and the tip portion 10o is widened to the maximum, the side bent portion 1b of the scaffold plate 1 is fitted into this space portion, and the state as shown in FIG.

  After the side bent portion 1b of the scaffolding plate 1 is fitted between the lower surface of the skirting board main body 5 and the hook portion 10 on the lower side of the gripping metal 9 as described above, it is shown in FIG. Thus, by rotating the operating lever 8 upward, the slide plate 9a of the gripping bracket 9 is slid upward through the leaf spring 11, the side bent portion 1b of the scaffold plate 1 is gripped by the hook portion 10, and further When the operation lever 8 is rotated to stand up, the slide plate 9a is slid to the upper limit position of the slide range via the leaf spring 11 as shown in (d), and the hook portion 10 is bent to the side bent portion 1b of the scaffold plate 1. The bottom plate portion 9b of the hook portion 10 is in contact with the lower surface 1bo of the side bent portion 1b, and the upper end portion 10o of the hook portion 10, which is the tip portion of the hook portion 10, is on the lower surface of the top plate portion 1a of the scaffold plate 1. In contact It is locked.

  Thus, by making the operating lever 8 stand up, the hook portion 10 of the gripping metal 9 is locked at the position where the side bent portion 1b of the scaffold plate 1 is gripped. In this case, the upper end portion of the hook portion 10 is temporarily assumed. Assuming that 10o is not in contact with the lower surface of the top plate portion 1a of the scaffold plate 1 and that the hook portion 10 is locked in a state where the side plate bent portion 1b of the scaffold plate 1 is only gripped, When a large lateral load is applied from the inside of the scaffold plate 1, there is a possibility that a large bending moment acts on the side bent portion 1 b due to the slide plate 9 a of the gripping metal 9 and deforms. However, in this one-touch lock fitting 6, the hook portion 10 grips the side bent portion 1b of the scaffold plate 1, and at the same time, the tip portion 10o of the hook portion 10 is supported by the lower surface of the top plate portion 1a of the scaffold plate 1. For this reason, the side bent portion 1b is not subjected to large bending, and its deformation is prevented.

  In this case, the hook portion 10 of the gripping metal 9 grasps the side surface bent portion 1b of the scaffold plate 1 so that the bottom plate portion 9b of the hook portion 10 contacts the lower surface 1bo of the side surface bent portion 1b, and the tip portion of the hook portion 10 Since 10o abuts on the lower surface of the top plate portion 1a of the scaffold plate 1, the hook portion 10 can accurately hold the side bent portion 1b, and the top of the hook portion 10 and the scaffold plate 1 can be secured. The plate portion 1a and the side bent portion 1b are integrated, and the baseboard body 5 can be stably and firmly fixed to the scaffold plate 1.

  As described above, the bottom plate portion 9b of the hook portion 10 is in contact with the lower surface 1bo of the side bent portion 1b, and the tip portion 10o of the hook portion 10 is in contact with the lower surface of the top plate portion 1a of the scaffold plate 1. However, the most important thing in this gripping metal 9 is that the tip portion 10o of the hook portion 10 of the top plate portion 1a of the scaffold plate 1 is in a state where the hook portion 10 grips the side bent portion 1b of the scaffold plate 1. Since it is in contact with the lower surface, the bottom plate portion 9b of the hook portion 10 may not be in contact with the lower surface 1bo of the side bent portion 1b and may be spaced apart from the lower surface 1bo to some extent.

  In order to remove the skirting board main body 5 from the scaffold board 1, the attachment procedure described with reference to FIGS. That is, when the operating lever 8 in the standing posture as shown in (d) is gripped by the handle 8o and rotated downward as shown in (c), the slide plate 9a is moved by the leaf spring 11 interlocked with the operating lever 8. By sliding downward and rotating the operation lever 8 further downward, the slide plate 9a slides to the lower limit position of the slide range as shown in FIG. Since the distance from the distal end portion 10o is maximized, the base metal body 5 can be detached from the scaffold board 1 by pulling the gripping metal 9 from the side bent portion 1b of the scaffold board 1 in this state.

  As described above, the scaffold board baseboard 4 is provided with a plurality of one-touch lock fittings 6 on the outer surface side of the baseboard body 5, and the baseboard 4 is attached on the side edge 1 a of the scaffold board 16. Sometimes, by rotating the operation lever 8 downward, the slide plate 9a of the gripping metal piece 9 is slid to the lower limit position of the slide range via the leaf spring 11, and the lower surface of the baseboard body 5 and the tip portion 10o of the hook portion 10 are moved. From the state where the distance between the slide plate 9a and the side plate 1b is set to the maximum, after the side bent portion 1b of the scaffolding plate 1 is fitted, the operation lever 8 is rotated upward to bring the slide plate 9a to the upper limit position. The hook portion 10 of the gripping metal 9 grips the side bent portion 1b of the scaffold plate 1, the tip portion 10o of the hook portion 10 is locked in contact with the lower surface of the top plate portion 1a of the scaffold plate 1, and the baseboard 4 From scaffolding board 1 When removing, the handle 9 is unlocked simply by rotating the operating lever 8 in the standing posture downward, so that the attachment to the scaffold plate 1 and the removal from the scaffold plate 1 can be easily performed with one touch. it can.

  Further, in the one-touch lock fitting 6 of the scaffold board skirting board 4, when the operation lever 8 stands up and the gripping fitting 9 is in the locked position, the handle 8 o formed at the upper end of the operation lever 8 is the skirting board body 5. Therefore, the operation lever 8 can be easily operated. In this embodiment, the handle 8o of the operation lever 8 protrudes upward from the upper end of the baseboard body 5. However, the handle 8o of the operation lever 8 extends outward from the outer surface side of the baseboard body 5. It may come to protrude. In any case, the handle 8o of the operation lever 8 is not housed inside the skirting board body 5 when the operation lever 8 is in the standing posture, and needs to protrude to the outside of the skirting board body 5. Thus, the operation of the operation lever 8 becomes easy.

  Further, as shown in FIG. 6, when the skirting board body 5 is placed on the side edge of the top plate part 1 a of the scaffolding board 1, the skirting board body 5 protrudes from the lower surface of the lower flange 5 c of the skirting board body 5. Since the raised ridge portion 5o engages with the recessed portion 1o formed on the top surface of the top plate portion 1a of the scaffold plate 1, the baseboard body 5 is not displaced on the top plate portion 1a. Retained.

  In the above-described embodiment, the one-touch lock fittings 6 are provided at two positions in the longitudinal direction of the skirting board 4, but when the skirting board 4 is short in length, or the skirting board 4 is used as the wife of the scaffold board 1. When it is provided on the side, the total length of the skirting board is, for example, about 50 cm. When the total length of the skirting board is short as described above, it may be sufficient to provide the one-touch lock fitting 6 alone at the center part in the longitudinal direction of the skirting board. .
