Two grooves 9 are provided on the upper surface of the upper protrusion 7a to fit and support the scaffold board support arm 4, and are perpendicular to each other and the round holes 8 of the protrusion 7 serve as intersections. One is formed parallel to the protruding direction of the protruding part 7, the other perpendicular to the protruding direction, and the scaffold board support arm 4 is selectively fitted into the two groove parts 9.

[0006]

[Operation] By inserting the bar 5, which is a part of the bracket 3, into the vertically opposing round holes 8 of the upper and lower protrusions 7 of the bracket hardware 2, and providing the stopper 6 on the bar 5, the bar 5
The bracket hardware 2 and the bracket 3 are integrated without coming out of the round hole 8. Further, two holes are formed on the upper surface of the upper protrusion 7a at right angles to each other and the round holes 8 of the protrusion 7 serve as intersections.
By providing two grooves 9, one parallel to the protrusion direction of the protrusion 7 and the other perpendicular to the protrusion direction, the scaffolding board support arm 4 is selectively fitted into the two grooves 9. If necessary, the mounting direction of the bracket can be changed during construction without removing the bracket from the bracket hardware.

EXAMPLES The present invention will be described in detail below based on examples. As shown in FIG. 1, the scaffold board support device is composed of a metal bracket 2 and a bracket 3. The bracket hardware 2 consists of a mounting part 20 to the column 1 and a protruding part 7 into which the bracket 3 is inserted. A groove 10 for fitting into the flange 21 of the column 1 made of H-shaped steel is provided at the rear of the mounting portion 20, and this groove 10 opens rearward and in the vertical direction. Further, bolts 11 and nuts 12 for fixing the bracket hardware 2 to the pillar 1 are attached to the mounting part 20,
Of these, the nut 12 is attached to the surface of the bracket hardware 2 by welding. The protruding portion 7 projects forward from the upper and lower ends of the attachment portion 20, and the upper and lower protruding portions 7 are provided with round holes 8 so as to face each other in the vertical direction. Further, on the upper surface of the upper protrusion 7a, two grooves 9a and 9b are provided at right angles to each other and the round holes 8 of the protrusion 7 intersect.
The other groove portion 9b is formed to be perpendicular to the protruding direction. Next, the bracket 3 includes a bar 5 inserted into the round hole 8 of the vertical protrusion 7, a scaffold board support arm 4 attached to its upper end in a direction perpendicular to the bar 5, and a stopper 6 provided at its lower end. and a reinforcing member 25 that connects the bar 5 and the scaffold board support arm 4. Two protrusions 15 are provided projecting from the upper surface of the scaffold board support arm 4, into which the scaffold board 30 is fitted and fixed. One is provided at one end of the scaffold board support arm 4, and the other is provided near the center of the scaffold board support arm 4. Note that the two protrusions 1
The width between 5 and 5 is matched to the width of the scaffold board 30. Further, the stopper 6 is provided to prevent the rod 5 inserted into the round hole 8 from coming out of the round hole 8.
It has a larger outer diameter. Further, both ends of the reinforcing member 25 are attached to one end of the lower surface of the scaffold board support arm 4 opposite to the end to which the bar 5 is attached, and near the center of the bar 5.

As shown in FIG. 1, the pillar 1 is fitted into the groove 10 provided in the mounting portion 20 of the bracket hardware 2.
The bracket hardware 2 is fixed to the pillar 1 by tightening the bolt 11 through the nut. Next, by sliding and rotating the bracket 3 inserted into the round hole 8 provided in the protrusion 7 of the bracket hardware 2 in the vertical direction, the groove provided on the upper surface of the upper protrusion 7a of the bracket hardware 2 is removed. Insert the scaffold board support arm 4 into the bracket 3.
to be fixed. Here, if you want to arrange the scaffold parallel to the protruding direction of the protrusion 7, fit the scaffold board support arm 4 into the groove 9a and fix the bracket 3.
Scaffolding board 30 between two protrusions 15 provided on the top surface of
Insert to form a scaffold. Also, if you want to place the scaffold in a direction perpendicular to the protrusion direction of the protrusion 7 from this state during construction, push the bracket 3 upward along the round hole 8 of the protrusion 7 and insert the scaffold board support arm from the groove 9a. Remove bracket 4 and rotate bracket 3 by 90 degrees. and,
Similarly, the scaffold board support arm 4 is fitted into the groove 9b to fix the bracket 3, and the scaffold board 30 is fitted between the two protrusions 15 provided on the upper surface of the scaffold board support arm 4 to form a scaffold. . In this manner, the bracket is selectively fixed in a direction parallel or perpendicular to the protruding direction of the protruding portion 7 to form a scaffold without removing the bracket hardware 2 during construction.

[Effects of the Invention] As described above, the present invention can be achieved by inserting a bar, which is a part of the bracket, into the opposing round holes of the upper and lower protrusions of the bracket hardware, and providing a stopper on the bar.
Since the bar material does not fall out of the round hole and the bracket hardware and bracket are integrated, there is no need to install the bracket hardware and the bracket separately when installing it on a pillar. It has the effect of improving. In addition, two grooves are provided on the upper surface of the upper protrusion so that they are perpendicular to each other and the round holes of the protrusion intersect, one parallel to the protrusion direction of the protrusion and the other perpendicular to the protrusion direction. By selectively fitting the scaffold board support arms into the two grooves, the mounting direction of the bracket can be changed as necessary without removing the bracket from the bracket hardware during construction, making it possible to The effect is that the direction can be changed easily, improving work efficiency on site.
