When the tightening nut 10 screwed into the tightening bolt 9 is tightened, the rotating arm 6 is pressed in the closing direction, and the fixing strength to the support can be adjusted by tightening the support.

  Since the clamp 2 can be rotated around the support column at the temporary fixing stage where the tightening amount of the tightening bolt 9 and the tightening nut 10 is loose, the direction with respect to the support shaft can be changed. In addition, the support | pillar of the assembly scaffold generally used is circular in cross section, and the attachment direction of the clamp 2 with respect to a support | pillar can be made into arbitrary angles.

  The connecting portion 3 is an elongated portion extending in one direction from the clamp body 5 of the clamp 2. In this embodiment, the direction with respect to the support | pillar at the time of attachment changes by changing the attachment direction of the clamp 2. FIG. The connecting portion 3 according to the present embodiment is configured as a separate member from the clamp 2 and is fixed to the clamp body. The connecting portion 3 has a configuration in which a tip portion of a rod-like member is bent at a right angle, and includes an extending portion 13 extending in a direction perpendicular to the support column and a fixing portion 14 fixed to the clamp 2. The connecting part 3 may be formed integrally with the clamp 2.

  The fixing portion 14 is fixed to the clamp body 5 by various bonding methods such as welding and bonding. Therefore, the relative position of the extending portion 13 with respect to the clamp 2 is always constant, and is disposed so as to extend in one direction with respect to the clamp 2. In the present embodiment, the length L of the extending portion 13 is approximately 5 to 20 cm, more preferably approximately 10 cm. According to the size of the gap generated between the support column 50 and the scaffolding plate 52, the extension portions 13 having different lengths may be used as appropriate. In this embodiment, generally, the distance between the columns of the assembly scaffold is 60 cm, and the width of the scaffold plate is 40 cm. Therefore, the length of the extending portion 13 is determined, and the dimensions of the assembly scaffold used are It is sufficient to use ones having different lengths as appropriate.

  The holding portion 4 is connected to the tip of the extending portion 13 of the connecting portion 3. The holding part 4 is a member having a U-shaped cross section, and includes an upper surface 15 and support surfaces 16 that are located on both ends of the upper surface and face each other. The sandwiching portion 4 inserts a baseboard between the support surfaces 16 facing each other from the upper side of the baseboard, and sandwiches the baseboard. The distance D between the supporting surfaces 16 facing each other is configured to be approximately 40 mm in the present embodiment in accordance with the thickness of a commonly used skirting board. In addition, the distance D between the support surfaces 16 which the holding part 4 opposes can be suitably selected so that it may become a little larger than the thickness dimension of the baseboard to support.

  The connecting portion 3 and the holding portion 4 are connected by riveting so that the holding portion 4 can rotate around the rivet 17. Therefore, the relative angle of the holding part 4 with respect to the connecting part 3 can be changed, and the angle can be adjusted according to the mounting direction of the clamp 2 described later.

  Note that the connection between the connecting portion and the holding portion is not limited to riveting, and bolts and nuts may be used as shown in FIG. In the example of FIG. 8, a bolt 30 erected on the upper surface 15 side of the holding portion 4 and a nut 31 that is screwed into the bolt 30 are provided. In this example, since the clamping part 4 and the connection part 3 are connected using the bolt 30 and the nut 31, the clamping part and the connection part can be detachably connected, and the bolt and the nut can be tightened. By adjusting the amount, it is possible to easily change and fix the relative rotation angle between the sandwiching portion and the connecting portion. Therefore, it is possible to use a holding part having an appropriate size according to the thickness dimension of the skirting board. Further, after attaching the skirting board, the clamping part and the connecting part are fixed to increase the attachment of the skirting board. be able to.

  FIG. 3 is a diagram showing a state where the baseboard of the scaffold baseboard attachment of FIG. 1 is attached. As shown in FIG. 3, the baseboard 40 to be fixed is placed on a horizontal horizontal member 51 provided between the columns 50. In FIG. 3, the scaffold 53 is illustrated with the frame 53 and the top 54 formed of different members, but the configuration of the scaffold is not limited thereto. Further, in FIG. 3, only one horizontal horizontal member 51 is illustrated, but actually, a plurality of horizontal horizontal members 51 parallel to each other are arranged, and the skirting board 40 includes a plurality of horizontal horizontal members 51. 51 is suspended and arranged. The skirting board 40 is fixed along the side edge 55 of the frame 53 of the scaffolding plate 52.

  In order to attach the skirting board 40 along the side edge 55 of the frame 53 of the scaffolding plate 52 using the attachment skirting board for scaffolding, it is preferable to carry out as follows. In order to hold the skirting board 40 in an upright state, the skirting board is placed upright on the horizontal horizontal member 51. At this time, it is preferable that the skirting board 40 is disposed close to the support 50 and leans against the support 50.

  The clamp 2 of the fixture 1 is attached to a support | pillar. At this time, tightening of the clamp 2 is weakened to a temporary fixing state. Further, the sandwiching portion 4 is inserted into the sandwiching portion 4 from the upper surface 41 side so that the sandwiching portion 4 sandwiches the base plate surface 42 in the thickness direction. At this time, the angle of the clamp 2 in the temporarily fixed state is adjusted so that the skirting board 40 standing on the support 50 can be supported.

  When the temporary fixing of the skirting board 40 is completed, the skirting board 40 is moved so as to approach the side edge 55 of the scaffold board 50. At this time, the fixture 1 rotates around the column axis of the column 50. When the position of the skirting board 40 is determined, tightening of the clamp 2 is strengthened, and the clamp 2 and the column 50 are fixed.

  In addition, by adjusting the mounting angle of the clamp 2 according to the gap between the side edge 55 of the scaffold plate 52 and the support column 50, the side edge 55 of the scaffold plate 52 according to the distance between the side wall of the scaffold plate 52 and the support column. The skirting board 40 can be attached along That is, by adjusting the mounting angle of the clamp 2 along the column 50 having a circular cross section, the distance between the column 50 and the holding portion 4 can be changed.

  As shown in FIG. 4, when the attachment angle θ <b> 1 is increased, the distance A between the support column 50 and the skirting board 40 is increased by the length of the extending portion 13 of the connecting portion 3. On the other hand, by reducing the attachment angle θ2, the connecting portion 3 faces in an oblique direction, so the distance B between the support column 50 and the skirting board 40 can be reduced.

  Next, a modified example of the scaffolding skirting fixture according to the present embodiment will be described. Since the scaffolding baseboard fixture according to the modified example has a clamp configuration different from that of the scaffolding baseboard attachment according to the embodiment, only the clamp configuration of the deformed portion will be described.

(First modification)
FIG. 5A is a plan view of a clamp used in the scaffolding skirting fixture according to the first modification. FIG. 5B is a plan view of the clamp in an open state. FIG. 6 is a sectional view of the clamp. The clamp 20 includes a clamp body 21 and a rotating arm 22. The clamp main body 21 and the rotating arm 22 are rotatably connected by a support shaft 23, and can take a closed position shown in FIG. 5A and an open position shown in FIG. 5B. As shown in FIG. 6, the clamp main body 21 is provided with a rotary arm insertion space, and the clamp main body 21 is disposed so as to be sandwiched between the clamp main body 21 by entering the closed rotary arm 22. .

  Through holes 24 and 25 are provided in overlapping portions of the clamp body 21 and the rotating arm 22 on the distal end side, respectively. Each of the through holes 24 and 25 is configured to have substantially the same size, and when the rotating arm 22 is in a closed state, the three through holes 24 and 25 overlap in the thickness direction of the clamp 20, and from above the clamp 20.

The width of the wedge member is configured such that the tip portion is smaller than the width size of the through holes 24 and 25 and the thickest upper end portion is larger than the width size of the through holes 24 and 25.

  FIG. 7 is a diagram for explaining the clamping principle of the clamp. When the wedge member 26 is inserted from the upper side of the clamp 20 as indicated by an arrow 60, the inclined surface 27 of the wedge member comes into contact with the front side 24 a of the through hole 24 of the clamp body 21. On the other hand, the vertical surface 28 of the wedge member abuts on the back end 25 b of the through hole 25 of the rotating arm 22. In this state, when the wedge member 26 is pushed downward in the figure, the width of the wedge member 26 increases, so the distance between the front side 24a of the through hole 24 and the back side end 25b of the through hole 25 increases, and the rotation of the wedge member 26 increases. The moving arm 22 is tightened more strongly.

  Therefore, the clamp according to the modification can adjust the tightening amount of the rotating arm 22 by adjusting the insertion depth of the wedge member, and can adjust the tightening strength to the support column 50. It is possible to easily adjust the temporary fixing and fixing to the at the same time, and at the same time, it can be attached and detached with one touch.

  The post insertion groove 35 c is provided with a notch 35 d for inserting the wedge member 34. Since the notch 35d inserts and supports the wedge member 34, the notch dimension is lower in the notch dimension B1 provided in the upper engaging portion 35 than the direction in which the wedge member 34 is inserted. It is comprised larger than the notch dimension B2 provided in the engaging part 35 of this.

  As shown in FIG. 10B, the wedge member 34 is a rod-like member that is configured to become narrower from the upper end 34a toward the tip 34b. Further, as shown in FIG. 10A, the cross section is formed in a concave shape in order to stably engage the wedge member 34 with the curved surface of the surface of the column 50 at the time of clamp engagement.

  In order to fix the clamp 32 to the support 50, as shown in FIG. 11, the clamp 32 is rotated 90 degrees, and the support 50 is attached to the two support members 36 from the side where the support portion 36 is not provided as shown by the arrows. Insert between the joints 35.

  Then, as shown by the arrow in FIG. 12, after the support 50 is pushed into the clamp, the clamp is rotated, and the support 50 is inserted into the support insertion groove from the openings of the side edges 33a and 33b of the engaging portion 35. As described above, since the openings on the side edges of the engaging portion 35 are provided on the opposite side edges, the column 50 can be inserted into the column insertion groove 35c by the rotation of the clamp.

  Next, the wedge member 34 is inserted into the cutout 35d. Since the wedge member 34 is configured so that the tip end side is narrowed, the clamp body 33 can be pressed against the column side and fixed according to the driving amount.

  Thus, according to the clamp concerning a 2nd modification, the operation | work which attaches the attachment of the baseboard for scaffolding to a support | pillar can be saved, and the effort of attachment can be reduced.

  In addition, this invention is not limited to the said embodiment, It can implement in another various aspect. For example, as illustrated in FIG. 2B, the extending portion 13 is provided on the lower surface side of the clamp 2, but may be provided on the upper surface side.
