本実施例では、前記結合材20に設けた窪み部222と、前記前記姿勢制御材30に設けた突出部321との係合関係でもって、係合機構Aを構成している。
<5> Engagement Mechanism The engagement mechanism A is a mechanism for positioning at least one location between the binding material 20 and the attitude control material 30 and positioning the binding material 20 with respect to the main body material 10. .
In this embodiment, the engagement mechanism A is configured by the engagement relationship between the recess 222 provided in the binding material 20 and the protrusion 321 provided in the posture control material 30.

<6>使用態様
次に、図1,図3を参照しながら、本実施例に係るクサビ緊結具の使用態様について説明する。
<6> Usage Mode Next, a usage mode of the wedge binding device according to the present embodiment will be described with reference to FIGS. 1 and 3.

<6.1>各部材の組立(図1)
まず、本体材10の挿通孔12から姿勢制御材30を差しこんで収容空間14内に配置する。
その後、結合材20の前後方向の位置を、やや前方にずらした状態で挿通孔12に差し入れる。
そして、窪み部222よりも下方の接触面223aで姿勢制御材30の前方片部32を後方に押し込んで結合材20の前後方向の位置を正しい位置においた状態で、結合材20を下方へと挿入する。
このとき、姿勢制御材30の前方片部32は、初期形状に復元しようと前方側に付勢された状態を呈している。
<6.1> Assembly of each member (Fig. 1)
First, the posture control member 30 is inserted from the insertion hole 12 of the main body member 10 and disposed in the accommodation space 14.
Then, the position of the binding material 20 in the front-rear direction is inserted into the insertion hole 12 with the position slightly shifted forward.
Then, with the contact surface 223a below the recess 222, the front piece 32 of the posture control member 30 is pushed backward to place the binding member 20 in the correct position in the front-rear direction. insert.
At this time, the front piece 32 of the posture control member 30 is in a state of being biased forward so as to restore the initial shape.

<6.2>結合材の自立姿勢(図3(a))
結合材20の挿入が進んでいくと、摺動部22の窪み部222による隙間を埋めるように姿勢制御材30の突出部321が前方へと押し出される。
このとき、結合材20は、窪み部222と突出部321との間の係止状態によって自立した姿勢を保持するように位置決めされる。
また、クサビ部21の下端は、未だ切欠き11に露出しておらず、本体材10を支柱XのフランジYに収容自在な状態である。
さらに、この結合材20の自立状態は、前記した姿勢制御材30の付勢によって維持されているため、クサビ緊結具そのものを揺らしたり、傾けたりする動作を行っても、自立状態が解除されることはない。
よって、フランジYへの取付作業時に、作業員が結合材20の姿勢制御を意識する必要は無い。
<6.2> Free-standing posture of binder (FIG. 3 (a))
As insertion of the binding material 20 proceeds, the protruding portion 321 of the attitude control material 30 is pushed forward so as to fill a gap formed by the recess 222 of the sliding portion 22.
At this time, the binding material 20 is positioned so as to maintain a self-supporting posture by the locking state between the recess 222 and the protrusion 321.
Moreover, the lower end of the wedge part 21 is not yet exposed to the notch 11, and the main body material 10 can be accommodated in the flange Y of the column X.
Further, since the self-standing state of the binding material 20 is maintained by the bias of the posture control material 30 described above, the self-standing state is released even if the wedge binding device itself is shaken or tilted. There is nothing.
Therefore, it is not necessary for the worker to be aware of the posture control of the binding material 20 during the attachment work to the flange Y.

なお、この結合材20の自立状態において、摺動部22の下端が本体材10から露出しているため、初回の組立時には貫通孔221にリベット23などを設けて抜け止め部を形成すればよい。   Since the lower end of the sliding portion 22 is exposed from the main body material 10 in the self-standing state of the binding material 20, a rivet 23 or the like may be provided in the through hole 221 to form a retaining portion at the first assembly. .

<6.3>結合材の緊結状態(図3(b))
結合材20の打突部212をハンマーで打撃することで、結合材20を下方へと押し下げる。
このとき、窪み部222より上方の接触面223bが、再度姿勢制御材30の前方片部32を後方に押し込むため、突出部321が結合材20の下移動に干渉することはない。
このように、クサビ部21による結合孔Zとのクサビ緊結が十分に行われた段階で、連結作業を完了する。
<6.3> Tightened state of the binder (FIG. 3B)
By hitting the striking portion 212 of the binding material 20 with a hammer, the binding material 20 is pushed down.
At this time, the contact surface 223b above the depression 222 pushes the front piece 32 of the posture control member 30 backward again, so that the protrusion 321 does not interfere with the downward movement of the binding member 20.
In this way, the connecting operation is completed when the wedge portion 21 is sufficiently tightened with the coupling hole Z.

<6.4>緊結状態の解除
足場の解体時など、支柱Xと水平材との連結を解除する場合には、摺動部22の下端をハンマーで打撃して結合材20を上移動させ、クサビ緊結を解除する。
このとき、リベット23などによる抜け止め部を設けておけば、結合材20が本体材10から抜け出ることはない。
また、緊結状態が解かれている状態では、摺動部22を作業員の手指で上下に移動させることで、容易に結合材20の自立姿勢を探り当てることができる。
<6.4> Releasing the Tightened State When releasing the connection between the support column X and the horizontal member, such as when the scaffold is dismantled, the lower end of the sliding portion 22 is struck with a hammer to move the binder 20 upward, Releases wedge binding.
At this time, if a retaining portion such as a rivet 23 is provided, the bonding material 20 does not come out of the main body material 10.
Moreover, in the state where the tight state is released, the self-standing posture of the binding material 20 can be easily found by moving the sliding portion 22 up and down with the fingers of the operator.

次に、図4を参照しながら本発明に係るクサビ緊結具の第2実施例について説明する。
本実施例では、結合材20を構成する摺動部22の背面に凸部224を設け、姿勢制御材30の前方片部32に設けた突出部321の肩部分に前記凸部224が載った状態で、結合材20の自立姿勢を呈するよう構成している。
本実施例によっても、実施例1と同等の効果を得ることができる。
Next, a second embodiment of the wedge binding device according to the present invention will be described with reference to FIG.
In this embodiment, a convex portion 224 is provided on the back surface of the sliding portion 22 constituting the binding material 20, and the convex portion 224 is placed on the shoulder portion of the protruding portion 321 provided on the front piece portion 32 of the attitude control material 30. In this state, the binder 20 is configured to exhibit a self-supporting posture.
According to the present embodiment, the same effect as that of the first embodiment can be obtained.

次に、図5を参照しながら本発明に係るクサビ緊結具の第3実施例について説明する。
本実施例では、結合材20を構成する摺動部22の背面に凸部224を設け、姿勢制御材30の前面の前方片部32を背面側に凹ませた凹部323に前記凸部224が収まる状態で、結合材20の自立姿勢を呈するよう構成している。
本実施例によっても、実施例1,2と同等の効果を得ることができる。
Next, a third embodiment of the wedge binding device according to the present invention will be described with reference to FIG.
In this embodiment, a convex portion 224 is provided on the back surface of the sliding portion 22 constituting the binding material 20, and the convex portion 224 is formed in a concave portion 323 in which the front piece 32 on the front surface of the posture control material 30 is recessed on the back surface side. It is comprised so that the self-standing attitude | position of the binding material 20 may be exhibited in the state which is settled.
According to this embodiment, the same effects as those of Embodiments 1 and 2 can be obtained.
