Japanese Patent Application Laid-Open No. 2018-123596

Among conventional temporary scaffolds, single-pipe scaffolds and framed scaffolds employ bolt-tightening clamps as a tightening means for tightening columns and connecting members when assembling the scaffolding. Impact drivers and ratchet wrenches are used as bolt tightening tools.

On the other hand, in the wedge binding type scaffolding, a wedge driven by a hammer is used as a binding means for binding a support column and a connecting member or the like when the scaffolding is assembled. Such a wedge fastening type scaffolding can easily and reliably fasten the pillars and connecting members, etc., by driving a wedge with a hammer in an instant, and its workability is better than that using a bolt fastening tool.

By the way, in the baseboard fixing device described in Patent Document 1, in order to clamp the support between two clamping members that constitute a pipe clamp and fix the pipe clamp to the support, the clamping members are attached to the outer periphery of the support. It is necessary to fasten the bolt and nut for closing movement around the part with a bolt tightening tool such as an impact driver or ratchet wrench. Therefore, with this baseboard fixture, it takes time to fasten the bolts and nuts using the bolt fastening tool, and the fastening and unfastening operations are troublesome.

Further, when using the baseboard fixture described in Patent Document 1 in a wedge-tied scaffold, it is necessary to prepare a bolting tool for the baseboard fixture in addition to the hammer for assembling the scaffold. Therefore, it is necessary to carry two tools, a hammer and a bolting tool, and the worker must switch between the hammer and the bolting tool when assembling the scaffolding and then fixing the baseboards. That is, despite the improvement in workability by using a hammer in assembling the scaffolding of the wedge-tying scaffolding, it is troublesome to use a bolting tool together to fix the baseboard in the wedge-tying scaffolding. will occur.

Further, in the baseboard fixture described in Patent Document 1, it is necessary for the worker to fix the pipe clamp to the support while pressing the baseboard fixing member against the baseboard. In order to fix the pipe clamp to the strut, the bolt tightening tool is used to close the two clamping members, so that the baseboard fixing member itself does not exert a force to hold down the baseboard. means that it is necessary to press the baseboard fixing member against the baseboard.

Therefore, if an unskilled worker cannot fix the pipe clamp to the support well, a gap may be formed between the baseboard fixing member and the baseboard, causing the baseboard to rattle or between the baseboard and the scaffolding board. There is also a risk that a gap will be created and objects will not be prevented from falling, and that the baseboard itself will fall off the scaffolding.

Also, even if the operator is experienced, it takes a lot of effort to securely fix a large number of baseboards across the scaffold to each of the corresponding stanchions.

As shown in FIGS. 2 to 6, the baseboard fixture 10 includes a post attachment member 20 which is attached to the post 1, for example, a circular outer peripheral portion and which can be attached to the post 1, and the post attachment member 20. It has a baseboard holding member 30 which is provided and holds the baseboard 4 by pinching it between itself and the strut 1 . Further, the baseboard fixture 10 has a wedge 40 that is driven into a wedge driving portion 20K provided in the support member 20 and is wedged to the outer peripheral portion of the support 1 to fasten the support member 20 to the support 1. As shown in FIG.

As shown in FIGS. 4 to 7, the strut mounting member 20 forms a U-shaped space S that can be attached to the outer periphery of the strut 1, and has a U-shaped portion 20U that splices onto the strut 1. Prepare. As shown in FIG. 7, the U-shaped portion 20U includes first and second plate-like portions 21 and 22 facing each other, and the first and second plate-like portions 21 and 22 are erected from both end sides. A connecting portion 23 is provided, and a U-shaped space S is formed by the first and second plate-like portions 21 and 22 and the connecting portion 23 . The post mounting member 20 has an arc surface 24 that follows the arc-shaped outer periphery of the post 1 at the intersection of the plate-like portion 22 and the connecting portion 23 that form the U-shaped space S. It is intended to secure a wide attachment surface with the part.

The baseboard holding member 30 has a lever-like baseboard holding portion 31 which is attached to and extends from the mounting portion 25 provided in the support post mounting member 20, and which enables the baseboard 4 to be held by being pressed between it and the support post 1. Prepare.

At this time, in the baseboard fixture 10, as shown in FIGS. 2, 3, and 5, the wedge 40 is driven into the wedge driving portion 20K provided in the post mounting member 20, and the post mounting member receives a force F. The direction R in which the baseboard 20 rotates around the support 1 due to the force F thereof, and the direction P in which the baseboard holding portion 31 of the baseboard holding member 30 provided on the support mounting member 20 presses the baseboard 4 against the support 1. and shall be consistent with each other. Therefore, an operator simply drives the wedge 40 with a hammer or the like while positioning the baseboard holding member 30 provided on the post mounting member 20 in front of the baseboard 4, so that the baseboard holding member 30 is attached to the baseboard. 4 is pressed against the strut 1.

In this embodiment, the baseboard holding member 30 is made of, for example, a bent body of a round bar as shown in FIG. That is, the baseboard holding member 30 pivots the rotating portion 32 between the mounting surface 25A of the mounting portion 25 of the post mounting member 20 and the mounting surface 25A by means of the shaft supporting portion 34A of the mounting piece 34 riveted on the mounting surface 25A. Support freely. The baseboard holding part 31 extends in an L-shape from the tip side of the rotating part 32, and the baseboard 4 can be held between the support post 1 by the vertical tip part of the L-shape. . Further, at the base end of the rotating portion 32, a detent portion 33 is arranged on the same plane as the baseboard holding portion 31 and extends by being bent in the opposite direction with the rotating portion 32 interposed therebetween. When the baseboard holding portion 31 and the rotating portion 32 are turned to the two-way turning ends (positions 31A and 31B in FIG. 4) of one side and the other side, the anti-rotation portion 33 is The baseboard holding portion 31 and the rotating portion 32 are stopped from rotating at their swivel ends by contacting the anti-rotation portion 26 defined on the mounting surface 25A of the mounting portion 25 of the post mounting member 20 .

The baseboard holding portion 31 and the rotating portion 32 of the baseboard holding member 30 are stopped from rotating when the anti-rotation portion 33 abuts the anti-rotation portion 26 of the post mounting member 20 at the turning end described above, and the baseboard holding portion 30 is held. When the portion 31 presses the baseboard 4 against the support 1 and holds the baseboard 4 between the support 1 and the support 1, the displacement in the direction opposite to the pressing direction is prevented.

In addition, a retaining portion 27 for retaining the anti-rotation portion 33 in a slidable state is protruded beside the anti-rotation portion 26 defined on the mounting surface 25A of the mounting portion 25 of the post mounting member 20. , the anti-rotation portion 33 is held between the mounting piece 34 and the retaining portion 27 .

Therefore, as shown in FIG. 1, the baseboard 4 is arranged along the side edge of the long scaffolding board 3, and is usually fixed to two or three pillars 1. When viewed from the front of the baseboard 4, the width The baseboard holding member 30 of the left scaffold fixture 10 provided near the left end along the longitudinal direction of the tree 4 holds the right front surface of the baseboard 4 against one corresponding support 1, and on the other hand, the baseboard. When the baseboard holding member 30 of the right baseboard fixture 10 provided near the right end along the longitudinal direction of the baseboard 4 holds the left front surface of the baseboard 4 with respect to the other one corresponding support 1, the baseboard The width with respect to the strut mounting member 20 is adjusted so that the baseboard holding portion 31 of the holding member 30 is turned to one side and the other side, for example, so that the rotation is stopped at both turning ends (positions 31A and 31B in FIG. 4) that are reversed 180 degrees. The mounting posture of the tree holding member 30 is reversed, the baseboard fixture 10 reversed to one side is used for the above-mentioned left side, and the baseboard fixture 10 reversed to the other side is used for the above-mentioned right side. can be done. As a result, in both the left and right baseboard fixtures 10, the direction R in which the support post mounting member 20 rotates around the support 1 by driving the wedge 40 becomes the same between the baseboard fixtures 10. The baseboard holding portion 31 of the baseboard holding member 30 always presses the baseboard 4 against the column 1.

The wedge 40 has a rod shape as shown in FIGS. 4 to 6 and 8, and has a striking portion 41 on the base end side to be struck with a hammer or the like, and a retaining portion 42 on the tip end side. The striking portion 41 has a base end portion of the wedge 40 that protrudes on both sides so that a first wedge driving opening 28 of the post mounting member 20, which will be described later, cannot be inserted from the outside to the inside of the U-shaped space S. It has a wide hitting area that is easy to hit with. The retaining portion 42 is composed of a blind rivet 44 or the like that is inserted into a mounting hole 43 on the tip end side of the wedge 40 and crimped or the like after the wedge 40 is driven into the support column mounting member 20 . The bulging portions 44A and 44B on both ends of the support member 20 make it impossible to insert a first wedge driving port 28, which will be described later, of the support member 20 from the inside to the outside of the U-shaped space S.

Thus, the post mounting member 20 is provided with a rectangular first wedge driving opening 28 in the first plate-shaped portion 21 of the U-shaped portion 20U. The first wedge driving port 28 does not let the hitting part 41 provided on the base end side of the wedge 40 pass from the outside to the inside of the U-shaped space S, and the retaining part 42 provided on the tip side of the wedge 40 is U-shaped. The rest of the entire length of the wedge 40 excluding the striking portion 41 and the retaining portion 42 is inserted without passing from the inside to the outside of the space S. The first wedge driving port 28 is supported by one side located farther from the connecting portion 23 .

Further, the post mounting member 20 is provided with a rectangular second wedge driving opening 29 in the second plate-shaped portion 22 of the U-shaped portion 20U. The second wedge driving opening 29 allows the wedge 40 to pass through the retaining portion 42 between the inside and the outside of the U-shaped space S, and allows the tip side portion of the wedge 40 to pass therethrough. The tip-side rear surface of the coupled wedge 40 is supported by one side of the second wedge driving port 29 located farther from the connecting portion 23 .

The strut mounting member 20 has first and second wedge driving openings 28 and 29 that form the aforementioned wedge driving portion 20K.

When the retaining portion 42 of the wedge 40 is retained in the first wedge driving opening 28 of the first plate-shaped portion 21 , the distal end portion of the wedge 40 including the retaining portion 42 is U-shaped in the U-shaped portion 21 . An L-shaped bent portion 21A formed to widen the opening of the U-shaped space S can stand by in a concave portion 21B formed facing the U-shaped space S.

Therefore, the baseboard fixture 10 inserts the portion of the wedge 40 excluding the striking portion 41 into the first wedge driving opening 28 provided in the first plate-shaped portion 21 of the post attachment member 20, and inserts the tip of the wedge 40 into the post. A retaining portion in which a rivet 44 is inserted into the mounting hole 43 at the tip of the wedge 40 and riveted while being inserted into the second wedge driving port 29 provided in the second plate-shaped portion 22 of the mounting member 20. Forming 42 constitutes an assembly comprising the post mounting member 20 , the skirting member 30 and the wedge 40 .
