（作用、効果）
以下、本実施形態の作用、効果を説明する。図８は、本実施形態の三方枠据付構造１２を説明する分解平面断面図である。 (Function, effect)
Hereinafter, the operation and effect of the present embodiment will be described. FIG. 8 is an exploded plan sectional view for explaining the three-way frame installation structure 12 of the present embodiment.

本実施形態の三方枠据付構造１２を用いて三方枠１０をエレベータ乗場１４に据え付けるには、まず、開口部Ｍに固定されたアンカーボルトＢＭに壁側連結部材２４のボルト挿通孔２４ｄを挿通させ、ネジ止めすることで壁側連結部材２４を開口部Ｍに着脱自在に固定する。開口部ＭにアンカーボルトＢＭが固定されていない場合には、打ち込み式のアンカーボルトを開口部Ｍに固定してから壁側連結部材２４の固定を行う。   In order to install the three-way frame 10 on the elevator hall 14 using the three-sided frame installation structure 12 of the present embodiment, first, the bolt insertion holes 24d of the wall side connecting member 24 are inserted into the anchor bolts BM fixed to the opening M. The wall side connecting member 24 is detachably fixed to the opening M by screwing. When the anchor bolt BM is not fixed to the opening M, the wall-side connecting member 24 is fixed after fixing the driving-type anchor bolt to the opening M.

次に、横枠１０ａ、縦枠１０ｂ、縦枠補強材１０ｃを組み立ててなる三方枠１０を建屋壁Ｗの開口部Ｍの所定位置に収め、三方枠１０の位置出しをする。そして、三方枠側連結部材２６を例えば下方から上昇させて切欠２６ｄに縦枠補強材１０ｃを入れ込ませ、更に、三方枠側連結部材２６を壁側連結部材２４に連結する。この連結を行う際、縦枠補強材１０ｃとアンカーボルトＷＰよの相互距離を、塞ぎ板２２のボルト締結が可能となるように調整しておき、長孔２４ｅにボルトを挿通させてナット２６ｆでボルト締結するとともに、長孔２６ｅにボルトを挿通させてナット２４ｆでボルト締結する。この結果、三方枠１０の左右方向Ｘへの移動が連結部材２０によって規制される。   Next, the three-sided frame 10 formed by assembling the horizontal frame 10a, the vertical frame 10b, and the vertical frame reinforcing material 10c is placed in a predetermined position of the opening M of the building wall W, and the three-sided frame 10 is positioned. Then, for example, the three-side frame side connecting member 26 is raised from below to insert the vertical frame reinforcing member 10 c into the notch 26 d, and the three-side frame side connecting member 26 is connected to the wall side connecting member 24. When this connection is made, the mutual distance between the vertical frame reinforcing member 10c and the anchor bolt WP is adjusted so that the bolt of the closing plate 22 can be fastened, and the bolt is inserted into the long hole 24e and the nut 26f is used. The bolt is fastened, and the bolt is inserted into the long hole 26e and fastened with the nut 24f. As a result, the movement of the three-way frame 10 in the left-right direction X is restricted by the connecting member 20.

その後、壁部ＷＰに固定されたアンカーボルトＷＰに塞ぎ板２２のボルト挿通孔２２ｄを挿通させ、ナット２３でネジ止めすることで塞ぎ板２２を壁部ＷＰに着脱自在に固定する。この結果、三方枠１０の前後方向Ｙ（特に昇降路方向である後方向）への移動が塞ぎ板２２によって規制される。なお、壁部ＷＰにアンカーボルトＢＰが固定されていない場合には、打ち込み式のアンカーボルトＢＰを壁部ＷＰに固定してからこれらの作業を行う。その際、アンカーボルトＢＰの固定位置は、縦枠補強材１０ｃの位置に対応させた位置とする。   Thereafter, the bolt insertion hole 22d of the blocking plate 22 is inserted into the anchor bolt WP fixed to the wall portion WP, and the nut 23 is screwed to fix the closing plate 22 to the wall portion WP in a detachable manner. As a result, the closing plate 22 restricts the movement of the three-way frame 10 in the front-rear direction Y (particularly the rearward direction that is the hoistway direction). In addition, when the anchor bolt BP is not fixed to the wall portion WP, these operations are performed after fixing the driving-type anchor bolt BP to the wall portion WP. At that time, the anchor bolt BP is fixed at a position corresponding to the position of the vertical frame reinforcing material 10c.

以上説明したように、本実施形態では、エレベータ乗場１４に三方枠１０を設置する際、溶接作業を行うことなく簡単なボルト締結作業を行うことで設置することができる。従って、乗りかご上という不安的な場所であっても容易に短時間で据付け作業を行うことができる。そして、ボルト締結箇所や位置調整箇所は少なく、作業の簡素化、作業時間の短縮化の観点では好ましい。   As described above, in the present embodiment, when installing the three-way frame 10 on the elevator hall 14, it can be installed by performing a simple bolt fastening operation without performing a welding operation. Therefore, the installation work can be easily performed in a short time even in an uneasy place on the car. And there are few bolt fastening places and position adjustment places, and it is preferable from a viewpoint of the simplification of work and shortening of work time.
