JP-A-2018-123596

Among the conventional temporary scaffolds, the single-tube scaffold and the frame scaffold use a bolt-tightening clamp as a fastening means for binding the support and the connecting material when assembling the scaffolding. Impact drivers and ratchet clamps are used as bolt tightening tools.

On the other hand, in the wedge binding type scaffold, a wedge driven by a hammer is adopted as a binding means for binding the support and the connecting material or the like when assembling the scaffold. Such a wedge-tied scaffold can easily and surely fasten a strut and a connecting material or the like by a momentary operation of driving a wedge with a hammer, and its workability is better than that using a bolt tightening tool.

By the way, in the wrench fixing tool described in Patent Document 1, in order to sandwich a support between two holding members constituting a pipe clamp and fix the pipe clamp to the support, the holding members are placed on the outer periphery of the support. It is necessary to fasten the bolts and nuts for closing around the part with a bolt tightening tool such as an impact driver or ratchet wrench. Therefore, with this brazing fixture, it takes time to fasten the bolts and nuts with the bolt tightening tool, and it takes time to fasten and release the bolts and nuts.

Further, when the scaffolding fixture described in Patent Document 1 is used in the wedge binding type scaffolding, it is necessary to prepare a bolt tightening tool for the scaffolding fixture in addition to the hammer for assembling the scaffolding. Therefore, it is necessary to carry two tools, a hammer and a bolt tightening tool, and the operator needs to change the hammer and the bolt tightening tool when assembling the scaffolding and then fixing the skirt. That is, although the workability is improved by using a hammer in assembling the scaffold in the wedge-tied scaffold, it is troublesome to use a bolting tool together for fixing the scaffold in the wedge-tied scaffold. Will occur.

Further, in the shackle fixture described in Patent Document 1, it is necessary for the operator to fix the pipe clamp to the support while pressing the shackle fixing member against the shackle. This is because in the operation of closing the two holding members using a bolt tightening tool in order to fix the pipe clamp to the support column, the operator does not exert a force to press the stile on the squeeze fixing member itself. Means that the work of pressing the squeeze fixing member against the squeeze is required.

Therefore, in the case of an unfamiliar worker, the pipe clamp cannot be fixed well to the support column, and a gap is created between the skirting member and the skirting board, causing the skirting board to rattle or between the skirting board and the scaffolding board. There is a risk that a gap will be created and it will not be possible to prevent objects from falling, or the skirting board itself will fall off the scaffolding.

Also, even if the operator is accustomed to it, a lot of work is required to securely fix a large number of timbers over the entire scaffold to each of the corresponding columns.

The fastening of 20 is released, the holding of the wedge 4 to the support column 1 by the wedge holding member 30 is also released, and the wedge 4 can be removed.

Therefore, according to the present embodiment, the following effects are exhibited.
(a) In the scaffolding skirting fixture 10, the support column mounting member 20 provided with the skirting board holding member 30 is fastened to the support column 1 by the wedge 40 driven into the wedge driving portion 20K provided in the support column mounting member 20. Is installed. Therefore, the strut mounting member 20 can be easily and surely fastened to the strut 1 by the momentary work of driving the wedge 40 with a hammer or the like without requiring the fastening work time as with a bolt tightening tool. 4 is held between the support column 1 and the support column 1 by the width bar holding member 30 provided on the support column mounting member 20.

Further, in the wedge binding type scaffold, the wedge driving hammer carried by the worker for assembling the scaffold 100 can also be used for the wedge driving work for fixing the width bar 4. That is, in the assembly and disassembly work of the scaffold 100, it is not necessary to separately prepare a bolt tightening tool or the like, and it does not take time and effort.

(b) In the scaffolding skirting fixture 10, the direction in which the strut mounting member 20 that receives the force F for driving the wedge 40 into the wedge driving portion 20K provided on the strut mounting member 20 rotates around the strut 1 by the force F. It is assumed that R and the direction P in which the wedge holding member 30 provided on the support column mounting member 20 presses the width member 4 against the support column 1 match. As a result, the operator simply drives the wedge 40 with a hammer or the like while the width bar holding member 30 provided on the support column mounting member 20 is positioned on the front surface of the width bar 4, and the support column is attached according to (a) above. At the same time that the member 20 is fastened to the support column 1, the wedge holding member 30 presses the width member 4 against the support column 1. It is not necessary for the operator to attach the support support member 20 to the support column 1 while pressing the width bar 4 to the side of the support column 1 by the width bar holding member 30, and even an unfamiliar worker can use the width bar holding member 30 and the support column 1. The width timber 4 can be fixed well without any gap between them. Therefore, there is no gap between the lumber holding member 30 and the scaffold 4, the lumber 4 does not rattle, and an object falls with a gap between the lumber 4 and the scaffolding plate 3. There is no risk that the lumber 4 itself will fall off the scaffold 100.

(c) The width bar 4 is arranged along the side side of the long scaffolding board 3, and is usually fixed to two or three columns 1.
