次に、上述した筋交い上端部取付金具３Ａを有する筋交い取付装置による筋交い２の取付施工について説明する。   Next, the installation work of the brace 2 by the brace attachment apparatus having the brace upper end part mounting bracket 3A described above will be described.

筋交い上端部取付金具３Ａを使用して筋交い２の上端部を吊りボルト１の上端部に取り付けるには、吊りボルト１の上端部を天井部ＳのインサートナットＴに螺着する前に、筋交い上端部取付金具３Ａの金具本体１４を吊りボルト１に挿通しておく。即ち、天井下地の組み付け前に、吊りボルト１を金具本体１４の下板部８にあるボルト挿通孔１２から上板部７のボルト挿通用長孔１１に貫通させた状態にして、天井下地を組み付けた時に金具本体１４が吊りボルト１の下端部側に位置する状態とし、この状態で筋交い２の上部螺軸５を金具本体１４の螺軸挿入用長孔１３から座板１５付きナット１６に螺入させておく。   In order to attach the upper end of the brace 2 to the upper end of the suspension bolt 1 using the brace upper end fitting 3A, before the upper end of the suspension bolt 1 is screwed to the insert nut T of the ceiling S, the upper end of the brace The bracket body 14 of the part mounting bracket 3A is inserted through the suspension bolt 1. That is, before assembling the ceiling foundation, the suspension bolt 1 is passed through the bolt insertion hole 12 in the lower plate portion 8 of the bracket main body 14 from the bolt insertion long hole 11 of the upper plate portion 7 so that the ceiling foundation is removed. When assembled, the bracket main body 14 is positioned on the lower end side of the suspension bolt 1. In this state, the upper screw shaft 5 of the brace 2 is moved from the screw shaft insertion long hole 13 of the bracket main body 14 to the nut 16 with the seat plate 15. Screw it in.

斯かる状態で、例えば野縁Ｎより下方の低位置で筋交い２を把持して、この筋交い２により筋交い上端部取付金具３Ａを吊りボルト１の下端部より上端部までスライドさせていって、吊りボルト１の上端部位置で、筋交い２を上部螺軸５のねじ込み方向に回転させることにより、上部螺軸５の先端部を、図２の(a) に示すように、金具本体１４の上板部７のボルト挿通用長孔１１に突入させると共に吊りボルト１のネジ部に食い込ませた状態とする。筋交い２の傾斜角度は、上部螺軸５を座板１５付きナット１６にねじ込んだまま、螺軸挿入用長孔１３で適宜に調整することができる。それから、図３に示すように筋交い２の下部螺軸６に連結した板状取付金具２３を野縁受けＵにビス２４止めする。こうして筋交い２の上端部及び下端部を吊りボルト１の上端部と野縁受けＵに対し夫々簡単容易に取り付け固定することができる。   In such a state, for example, the brace 2 is grasped at a lower position below the field edge N, and the brace upper end fitting 3A is slid from the lower end of the suspension bolt 1 to the upper end by the brace 2. At the position of the upper end of the bolt 1, the brace 2 is rotated in the screwing direction of the upper screw shaft 5, so that the tip of the upper screw shaft 5 is placed on the upper plate of the bracket main body 14 as shown in FIG. The bolt 7 is inserted into the bolt insertion long hole 11 of the portion 7 and is bitten into the threaded portion of the suspension bolt 1. The inclination angle of the brace 2 can be appropriately adjusted with the screw shaft insertion long hole 13 while the upper screw shaft 5 is screwed into the nut 16 with the seat plate 15. Then, as shown in FIG. 3, the plate-like mounting bracket 23 connected to the lower screw shaft 6 of the brace 2 is fixed to the field receiver U with screws 24. In this way, the upper end and the lower end of the brace 2 can be easily and easily attached and fixed to the upper end of the suspension bolt 1 and the field edge receiver U, respectively.

この場合、筋交い２の筋交い本体４が角パイプ（角筒状体）からなるため、筋交い２を強く回転させても筋交い本体４が捻じれ変形するおそれがなく、上部螺軸５を座板１５付きナット１６的確にねじ込むことができる。   In this case, since the bracing main body 4 of the brace 2 is formed of a square pipe (rectangular tubular body), there is no possibility that the bracing main body 4 is twisted and deformed even if the bracing 2 is strongly rotated, and the upper screw shaft 5 is attached to the seat plate 15. The nut 16 can be accurately screwed.

上記のように図２〜図４により説明した筋交い上端部取付金具３Ａは、吊りボルト１を天井部Ｓに取り付けて垂下する前に、金具本体１４を、ボルト挿通用長孔１１とボルト挿通孔１２と介して吊りボルト１に挿通して取り付けておく先付け式の取付金具であって、こうして金具本体１４を吊りボルト１に予め取り付けておけば、あとは、筋交い２の上部螺軸５を金具本体１４の螺軸挿入用長孔１３から座板１５付きナット１６に螺入させた状態で、筋交い２により筋交い上端部取付金具３Ａを吊りボルト１の下端部より上端部までスライドさせて、そこで筋交い２を回転させればよいから、作業者は、作業現場の床面あるいは作業台上での低位置からの遠隔操作によって、筋交い２を簡単容易にして且つ安全に取り付けることができる。なお、筋交い上端部取付金具３Ａは吊りボルト１を天井部Ｓに取り付ける前に該筋交い上端部取付金具３Ａを吊りボルト１の上端部から吊りボルト１に嵌め入れるようにした使用例であるが、これに対し、吊りボルト１を天井部Ｓに取り付けて吊りボルト１を垂下させた状態で、吊りボルト１の下端部にハンガーＨを取り付ける前に吊りボルト１の下端部から筋交い上端部取付金具３Ａを吊りボルト１に嵌め入れるようにしてもよい。要は、この実施形態の筋交い上端部取付金具３Ａは、吊りボルト１の上端部又は下端部が開放されている状態で吊りボルト１に取り付けられる先付け式の取付か金具である。   The brace upper end mounting bracket 3A described with reference to FIGS. 2 to 4 as described above is configured so that the bracket main body 14 is attached to the bolt insertion long hole 11 and the bolt insertion hole before the suspension bolt 1 is attached to the ceiling portion S and suspended. 12, and is attached to the suspension bolt 1 through the suspension bolt 1. If the bracket body 14 is previously attached to the suspension bolt 1, the upper screw shaft 5 of the brace 2 is attached to the bracket. With the brace 2 inserted into the nut 16 with the seat plate 15 from the screw shaft insertion slot 13 of the main body 14, the brace upper end fitting 3 </ b> A is slid from the lower end to the upper end of the suspension bolt 1. Since the brace 2 only needs to be rotated, the operator can easily and safely attach the brace 2 by remote operation from a low position on the floor of the work site or on the work table. The bracing upper end mounting bracket 3A is an example of use in which the bracing upper end mounting bracket 3A is fitted into the hanging bolt 1 from the upper end of the hanging bolt 1 before the hanging bolt 1 is attached to the ceiling S. On the other hand, in a state where the suspension bolt 1 is attached to the ceiling portion S and the suspension bolt 1 is suspended, before the hanger H is attached to the lower end portion of the suspension bolt 1, the brace upper end mounting bracket 3A May be fitted into the suspension bolt 1. In short, the brace upper end mounting bracket 3A of this embodiment is a tip-mounted mounting bracket that is attached to the suspension bolt 1 with the upper end or lower end of the suspension bolt 1 being open.

また、上記のように筋交い２を回転させて、上部螺軸５の先端部を金具本体１４の上板部７のボルト挿通用長孔１１に突入させると共に吊りボルト１のネジ部に食い込ませることによって、筋交い２の上端部を吊りボルト１の上端部側に確実に固定させることができる。   Further, the brace 2 is rotated as described above so that the tip end portion of the upper screw shaft 5 is inserted into the bolt insertion long hole 11 of the upper plate portion 7 of the metal fitting body 14 and bites into the screw portion of the suspension bolt 1. Thus, the upper end portion of the brace 2 can be reliably fixed to the upper end portion side of the suspension bolt 1.

また、筋交い上端部取付金具３Ａの金具本体１４の上下板部７，８に設けてあるボルト挿通用長孔１１及びボルト挿通用孔１２には夫々、図２の(a) に示すように、吊りボルト１を挟んで筋交い２の上部螺軸５が位置する側と反対側の端部に、吊りボルト１のネジ部に食い込むネジ部食込突縁部４１，４１が形成されているから、筋交い２の上部螺軸５を螺進方向に回転させることにより、金具本体１４が上部螺軸５側へ引き込まれ、それによってボルト挿通用長孔１１及びボルト挿通用孔１２のネジ部食込突縁部１１ａ，１２ａが、吊りボルト１のネジ部に押し付けられて強く食い込み、筋交い上端部取付金具３Ａを吊りボルト１の上端部に強固に固定することができ、地震発生時の揺れに対して十分に対応可能となる。   Further, as shown in FIG. 2 (a), the bolt insertion long hole 11 and the bolt insertion hole 12 provided in the upper and lower plate portions 7 and 8 of the bracket main body 14 of the brace upper end mounting bracket 3A are as shown in FIG. Since threaded portion biting ridges 41 and 41 that bite into the threaded portion of the suspension bolt 1 are formed at the end opposite to the side where the upper screw shaft 5 of the brace 2 is located across the suspension bolt 1, By rotating the upper screw shaft 5 of the brace 2 in the screwing direction, the metal fitting main body 14 is drawn to the upper screw shaft 5 side, whereby the screw portion biting protrusion of the bolt insertion long hole 11 and the bolt insertion hole 12 is pulled. The edge portions 11a and 12a are pressed against the threaded portion of the suspension bolt 1 to bite in strongly, and the brace upper end mounting bracket 3A can be firmly fixed to the upper end portion of the suspension bolt 1 so that it can be prevented from shaking when an earthquake occurs. It becomes possible to respond sufficiently.

図２〜図４によって説明した筋交い上端部取付金具３Ａは、吊りボルト１の上端部を天井部Ｓに取り付ける前に又は吊りボルト１の下端部にハンガーＨを取り付ける前に、金具本体１４を吊りボルト１に挿通した状態に取り付けておく先付け式の取付金具であるが、図５には、吊りボルト１の上端部を天井部Ｓに取り付け且つ吊りボルト１の下端部にハンガーＨを介して野縁受けＵを取り付けた状態で、この吊りボルト１に金具本体１４を取り付けるようにする後付け式の筋交い上端部取付金具３Ｂを示す。   The brace upper end mounting bracket 3 </ b> A described with reference to FIGS. 2 to 4 suspends the bracket main body 14 before attaching the upper end of the suspension bolt 1 to the ceiling S or before attaching the hanger H to the lower end of the suspension bolt 1.
