  DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to the drawings. FIGS. 1 to 4 show a wedge-tightening type scaffolding plate holder A according to the present invention. The single-tube scaffolding column 1 is fitted from the side and supported on the polygonal flange 2 with the wedge hole 3 fixed to the column 1, and one corner 2a of the flange 2 is engaged. Hook locking shafts 6 and 6 on which the pair of hooks 5 and 5 provided at the respective ends of the hook-attached scaffolding plate 16 are locked are coaxially attached to the left and right ends of the box frame 4 that is configured as described above. The bracket body 7 is inserted into the bracket body 7 formed by protruding from the wedge hole 8 provided in the box frame 4 of the bracket body 7 and the wedge hole 3 of the flange 2. 1 and a wedge 9 adapted to be tightly fixed to 1. In addition, the scaffold board 16 latched by the hook latching shaft parts 6 and 6 of the metal fitting main body 7 is a scaffold board with a hook of a half size (240 mm width).

  The structure of the scaffolding plate bracket A will be described in more detail. The box frame 4 of the bracket body 7 is opened on the back side by the left and right side wall portions 10, 10, the front wall portion 11, and the upper and lower wall portions 12, 13. Is formed. In the upper wall portion 12 and the lower wall portion 13 of the box frame 4, fitting recesses 12 a and 13 a that fit into the side surface portion of the single-tube scaffolding column 1 are formed in a U shape in plan view from the front end portion. In addition, the upper wall portion 12 and the lower wall portion 13 are formed with wedge holes 8 and 8 corresponding to the wedge hole 3 of the flange 2 at positions vertically opposed to each other, and the upper wall portion 12 has the fitting recess 12a. Support part pieces 14 and 14 projecting downward from a predetermined position on both sides across the upper surface of the flange 2 and projecting from the upper surface of the flange 2 are provided. Further, the front wall portion 11 is formed with a square window portion 15 into which one corner portion 2a of a polygonal flange fixed to the single-tube scaffolding column 1 enters and engages.

  Each hook locking shaft portion 6 of the metal fitting main body 7 is attached with an egg-shaped fall prevention plate 17 at its outer end to prevent the hook 5 of the scaffolding plate 16 locked to the shaft member 6 from dropping. Yes.

  In the manufacture of the receiving metal body 7, the left and right side wall portions 10, 10 and the front wall portion 11 are formed in a U shape by pressing a strip-shaped steel plate, and each of the U-shaped bodies has a steel plate. The box frame 4 is formed by welding the upper wall portion 12 and the lower wall portion 13 formed by cutting out U-shaped fitting recesses 12a and 13a from the front end portions, respectively, and the upper wall of the box frame 4 Holes are formed in the portion 12 at predetermined positions on both sides with the fitting recess 12a in between, and support portion pieces 14 and 14 made of steel round bars are inserted from the respective holes so that the respective upper ends thereof are connected to the upper wall portion 12. Welding is also performed, and hook locking shafts 6 and 6 each made of a round steel pipe are welded to the left and right side wall portions 10 and 10 which are the left and right ends of the box frame 4, respectively, and are projected on the same axis. For example, an egg-shaped fall prevention plate 17 made of a steel plate is welded and fixed to the outer end portion of the shaft portion 6. , It is possible to produce a received fitting main body 7.

  In order to attach the bracket body 7 of the scaffold plate bracket A configured as described above to the single-tube scaffolding column 1, as can be seen from FIGS. 1 to 3, formed on the back side of the bracket body 7, The fitting recesses 12a and 13a of the upper and lower wall portions 12 and 13 of the box frame 4 are fitted to predetermined portions of the single-pipe scaffolding column 1 on which the scaffolding plate 16 is bridged, and are fixed to the column 1 in a polygonal shape. The flange 2 is inserted between the upper and lower wall portions 12 and 13 of the box frame 4, and one corner portion 2a of the polygonal flange 2 is inserted into the square window portion 15 in the front wall portion 11 of the box frame 4 from the inside. In addition, the support pieces 14 and 14 projecting downward from the upper wall portion 12 of the box frame 4 are supported on the upper surface of the flange 2, and in this state, the wedge 9 is placed in the box frame 4 as shown in FIG. A wedge hole on the lower wall portion 13 side from a wedge hole 8 on the upper wall portion 12 side through a wedge hole 3 on the flange 2 Inserted into, by impress with a hammer, it is possible to firmly fix the receiving box frame 4 of the main metal member 7 through the flange 2 to the single pipe scaffold posts 1. In this case, since one corner 2a of the flange 2 is plunged into the corner window portion 15 of the box frame 4 and the support pieces 14 and 14 on the box frame 4 side are supported on the upper surface of the flange 2, The box frame 4 does not play with respect to the flange 2, and the receiving metal body 7 can be fixed stably and firmly.

  A pair of hooks projecting at each end of the scaffolding plate 16 with respect to the hook locking shafts 6 and 6 of the receiving metal bodies 7 and 7 attached to the opposing portions of the adjacent single pipe scaffolding columns 1 and 1 in this way. By attaching 5 and 5, the attachment of the scaffold plate 16 is completed. This mounting state is shown in FIG. In this case, since the fall prevention plate 17 is attached to the outer end portion of the hook locking shaft portion 6, the hook 5 at each end portion of the scaffold plate 16 is received by the hook locking shaft portion 6 of the metal fitting body 7. When stopped, the hook 5 does not fall from the hook locking shaft portion 6 due to the lateral displacement of the scaffold plate 16 or the like.

  A raised portion 9a is formed at the tip (lower end) of the wedge 9, and when the wedge 9 is pulled upward, the raised portion 9a is thick, so that the upper wall portion 12 of the box frame 4 is thick. Therefore, the wedge 9 can be prevented from being lost. In this case, the wedge hole 8 on the lower wall portion 13 side is formed to be slightly wider so that it can be driven down through the wedge hole 8 on the lower wall portion 13 side without hindering the raised portion 9a. It has become.

  The scaffold plate bracket A described with reference to FIGS. 1 to 4 is a wedge-tightening type scaffold plate bracket in which the bracket body 7 is tightly fixed to the single-pipe scaffolding column 1 with a wedge 9. 8, a clamp-type scaffolding plate bracket B that is configured to fix the bracket main body 18 to the single tube scaffolding column 1 by gripping the single column scaffolding column 1 with a pipe clamp attached to the bracket body 18. Show.

  FIG. 5 (a) is a perspective view of the scaffolding plate bracket B viewed from the front side of the bracket body 18, and FIG. 5B is a perspective view of the scaffolding plate bracket B viewed from the rear side. 6 is a perspective view showing a scaffold plate receiving device formed by combining the wedge-tightened type scaffold plate receiving metal fitting A shown in FIGS. 1 to 4 and the clamp type scaffolding plate receiving metal fitting shown in FIG. a) is a front view of the clamp-type scaffolding bracket bracket B, (b) is a plan view thereof, (c) is a rear view, and (d) is a right side view.
