従来の支柱と横木の連結技術にはつぎのような問題点を有する。
＜１＞横木を回転操作して支柱に連結する方法にあっては、重量の重たい横木を複数の作業員が手で持ち、所定の連結角度を保ちながら横木を回転操作しなければならないために、横木の連結に多くの時間と労力を要し、施工性に問題がある。
＜２＞特許文献１に開示された連結方法は、側方ボルトを横木の下部側面から上向きに差し込んだ後に、筒状の取付金具を貫通して形成した二つのねじ穴に位置合せをしてねじ込む必要があるため、施工性に問題がある。
＜３＞特許文献１に開示された連結方法は、横木を間に挟み込んで締め付けるため、側方ボルトが緩み易く、横木に径方向と軸方向の両方向へ向けたガタツキを生じ易い。 The conventional connecting technique of the support and the cross has the following problems.
<1> In the method of rotating the rung and connecting it to the column, multiple workers must hold the heavy rung by hand and rotate the rung while maintaining a predetermined connection angle. It takes a lot of time and labor to connect the cross, and there is a problem in workability.
<2> In the connection method disclosed in Patent Document 1, the side bolt is inserted upward from the lower side surface of the crosspiece, and then aligned with two screw holes formed through the cylindrical mounting bracket. Since it is necessary to screw, there is a problem in workability.
<3> Since the connection method disclosed in Patent Document 1 is clamped with the crosspieces sandwiched therebetween, the side bolts are easy to loosen, and the crosspieces tend to be loose in both the radial direction and the axial direction.

＜３＞調整ボルトの螺着（図５）
右方の横木２０の側面に形成した側部ボルト孔２２に調整ボルト３４を螺着する。
調整ボルト３４の先端部が横木２０の中心部に突出してテーパナット３３のテーパ面３３ａに当接するまで調整ボルト３４をねじ込んで支柱１０と右方の横木２０の間を連結する。
調整ボルト３４の先端部がテーパナット３３のテーパ面３３ａに当接することで、右方の横木２０が位置決めされて抜け出しが規制される。 <3> Screwing adjustment bolt (Fig. 5)
An adjustment bolt 34 is screwed into the side bolt hole 22 formed on the side surface of the right cross 20.
The adjustment bolt 34 is screwed in until the tip of the adjustment bolt 34 protrudes to the center of the crosspiece 20 and abuts against the tapered surface 33a of the taper nut 33, and the support 10 and the right crosspiece 20 are connected.
When the tip end of the adjustment bolt 34 abuts against the tapered surface 33a of the taper nut 33, the right cross 20 is positioned and the withdrawal is restricted.

横木２０の側部ボルト孔２２を真横に向けると調整ボルト３４の螺着作業を簡単に行えるが、側部ボルト孔２２の向きに制約は特になく、現場に応じて側部ボルト孔２２の向きを選択してもよい。
さらに調整ボルト３４の螺着本数は１本に限定されず、等間隔に複数本の調整ボルト３４を螺着するようにしてもよい。 When the side bolt hole 22 of the crosspiece 20 is directed to the side, the adjustment bolt 34 can be screwed easily. However, the direction of the side bolt hole 22 is not particularly limited, and the direction of the side bolt hole 22 depends on the site. May be selected.
Furthermore, the number of adjustment bolts 34 is not limited to one, and a plurality of adjustment bolts 34 may be screwed at equal intervals.

＜４＞ガタツキの解消（図５）
調整ボルト３４の先端部をテーパナット３３に単に当接させただけでは、支柱１０と右方の横木２０の連結部にガタつきを生じ易い。
このガタツキをなくすために調整ボルト３４を更にねじ込むと、調整ボルト３４の先端部がテーパナット３３の傾斜したテーパ面３３ａに沿って滑動し、調整ボルト３４の先端部がテーパ面３３ａの大径側から縮径側へ向けて滑動することで横木２０が支柱１０側へ引き寄せられる。
右方の横木２０の左方端が支柱１０の凹部１１の底面に押し当たることで、支柱１０と右方の横木２０との連結部にガタつきが解消される。 <4> Elimination of rattling (Figure 5)
If the tip end of the adjustment bolt 34 is simply brought into contact with the taper nut 33, rattling is likely to occur at the connecting portion between the support column 10 and the right crossbar 20.
When the adjustment bolt 34 is further screwed in to eliminate this rattling, the tip of the adjustment bolt 34 slides along the inclined taper surface 33a of the taper nut 33, and the tip of the adjustment bolt 34 moves from the large diameter side of the taper surface 33a. By sliding toward the reduced diameter side, the crosspiece 20 is drawn toward the column 10 side.
When the left end of the right cross 20 is pressed against the bottom surface of the recess 11 of the support column 10, rattling is eliminated from the connecting portion between the support column 10 and the right cross 20.

調整ボルト３４をねじ込むことでテーパナット３３のテーパ面３３ａに押圧力が作用しても、調整ボルト３４やテーパナット３３が緩まないので、調整ボルト３４に対するテーパナット３３の螺着位置が変位しない。
したがって、横木２０に外力等が作用しても支柱１０と右方の横木２０との連結部が緩むことがなく、長期間に亘って良好な連結状態を保持できる。
仮に何らかの原因で連結部が緩んでも調整ボルト３４を再度締付けするだけで連結部のガタツキを解消できる。 Even if a pressing force is applied to the tapered surface 33a of the taper nut 33 by screwing the adjustment bolt 34, the adjustment bolt 34 and the taper nut 33 are not loosened, so that the screwing position of the taper nut 33 with respect to the adjustment bolt 34 is not displaced.
Therefore, even if an external force or the like acts on the crosspiece 20, the connecting portion between the column 10 and the right crosspiece 20 does not loosen, and a good connection state can be maintained for a long period of time.
Even if the connecting portion is loosened for some reason, the looseness of the connecting portion can be eliminated by simply tightening the adjusting bolt 34 again.

調整ボルト３４が滑動し得るテーパ面３３ａの軸長の範囲に亘って右方の横木２０の引き寄せが可能であるため、連結ボルト３１に対するテーパナット３３の螺着位置が多少不正確であっても支柱１０と右方の横木２０の連結部のガタつきを吸収することができる。   Since the right crossbar 20 can be drawn over the range of the axial length of the tapered surface 33a through which the adjustment bolt 34 can slide, the support column can be supported even if the screwing position of the taper nut 33 to the connecting bolt 31 is somewhat inaccurate. The backlash of the connecting portion between the right and the horizontal bars 10 can be absorbed.

このように調整ボルト３４を締付けるだけの簡単な操作で以て、右方の横木２０を支柱１０に引き寄せして、ガタつきを解消した状態で強固に連結することができる。   In this way, the simple operation of simply tightening the adjusting bolt 34 enables the right crossbar 20 to be drawn to the column 10 and firmly connected in a state in which the play is eliminated.
