以下に本発明の好適な一実施形態を図面に基づいて説明すると、図１〜図６において、１は本発明に係る妻側先行手摺りを示し、この妻側先行手摺り１は、楔緊結式の足場を仮設するにあたり、既設の下段側足場板４から新設される上段側足場板４の先行手摺りとして、仮設足場の足場板幅方向に対向する支柱２，２間に取り付けるものである。足場板４は図６に図示している。   DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 to 6, reference numeral 1 denotes a wife-side leading handrail according to the present invention. When temporary scaffolding is installed, it is attached between the supporting columns 2 and 2 facing the scaffolding plate width direction of the temporary scaffolding as a leading handrail of the upper scaffolding plate 4 newly installed from the existing lower scaffolding plate 4. . The scaffold plate 4 is illustrated in FIG.

尚、楔緊結式足場は、建物躯体の外壁（図示せず）に近い側に鋼管からなる内側の支柱２を配置して、この内側支柱２を壁つなぎ材（図示せず）によって建物躯体の外壁に固定し、この内側支柱２に対向して外側支柱２を配置し、これら内外の支柱２，２間に横ステー１０を取り付け、建物躯体に沿って水平方向に対向する横ステー１０，１０間に足場板４を架け渡し、そして各内側及び外側の支柱２を順次高所に向かって連結しながら、上記の作業を繰り返すことによって、足場板を多段状に架設するもので、本発明に係る妻側先行手摺り１は、順次新設する上段側足場の先行手摺りとなり、架設作業の安全性を確保し、作業性の向上を図ることができる。各支柱２には長さ方向に所定間隔おきに楔孔３ａ付きフランジ３が設けてある。   In the wedge-tight scaffold, an inner column 2 made of a steel pipe is disposed on the side close to the outer wall (not shown) of the building frame, and the inner column 2 is connected to the building frame by a wall connecting material (not shown). The outer support 2 is fixed to the outer wall, the outer support 2 is arranged opposite to the inner support 2, the horizontal stay 10 is attached between the inner and outer support 2, 2, and the horizontal stays 10, 10 facing the horizontal direction along the building frame. The scaffolding plate 4 is laid in a multi-stage by repeating the above-mentioned operation while spanning the scaffolding plate 4 between them and sequentially connecting the inner and outer support columns 2 toward the height. The wife-side leading handrail 1 becomes a leading handrail for the upper-stage scaffolding that is sequentially newly installed, and can ensure the safety of the erection work and improve the workability. Each strut 2 is provided with flanges 3 with wedge holes 3a at predetermined intervals in the length direction.

この妻側先行手摺り１は、図１から分かるように、水平材５と、この水平材５の両端部に夫々一端部（上端部）がボルト・ナット１５（枢軸部）により枢着されて、互いに交差する一対の斜材６，７とからなるもので、水平材５と斜材６，７との各枢着端部には各斜材６，７側の端部に、支柱２のフランジ３の楔孔３ａに係止可能な係止部材８が設けられ、各斜材６，７の他端部（下端部）には、足場板幅方向に対向する支柱２，２間に横架される横ステー１０に係止可能な係止フック９が設けられている。   As shown in FIG. 1, the wife-side leading handrail 1 has a horizontal member 5 and one end portion (upper end portion) pivoted to both ends of the horizontal member 5 by bolts and nuts 15 (pivot portions). The pair of diagonal members 6, 7 intersecting each other, and the pivotal ends of the horizontal members 5 and the diagonal members 6, 7 are connected to the end portions of the diagonal members 6, 7, A locking member 8 that can be locked in the wedge hole 3a of the flange 3 is provided, and the other end portions (lower end portions) of the diagonal members 6 and 7 are laterally disposed between the support columns 2 and 2 facing the scaffold plate width direction. A locking hook 9 that can be locked to the horizontal stay 10 is provided.

係止部材８は、図２の(a) 〜(c) に示すように、斜材６の一端部に溶接によって固着された板状本体１２と、この板状本体１２の先端側に溶接によって下向きに一体に突出ように取り付けられた軸状体からなる挿入片１３とにより構成され、この挿入片１３は、上部側の径小軸部１３ａと下部側の径大軸部１３ｂとからなるもので、径小軸部１３ａと径大軸部１３ｂとの間に係止段部１４が形成されている。また、挿入片１３の径大軸部１３ｂは、その下部側が下窄まりテーパ状のガイド部１３ｂｏを形成している。   As shown in FIGS. 2A to 2C, the locking member 8 includes a plate-like body 12 fixed to one end of the diagonal member 6 by welding, and a distal end side of the plate-like body 12 by welding. The insertion piece 13 is composed of a shaft-like body attached so as to protrude integrally downward, and this insertion piece 13 is composed of an upper small diameter shaft portion 13a and a lower large diameter shaft portion 13b. Thus, a locking step portion 14 is formed between the small-diameter shaft portion 13a and the large-diameter shaft portion 13b. In addition, the large-diameter shaft portion 13b of the insertion piece 13 is narrowed at the lower side to form a tapered guide portion 13bo.

図３の(a) は妻側先行手摺り１を足場板幅方向に対向する内外の支柱２，２間に架設した時に係止部材８の挿入片１３がフランジ３の楔孔３ａに挿入した状態を示す。この挿入片１３は、径大軸部１３ｂの下部側が下窄まりテーパ状の挿入ガイド部１３ｂｏを形成しているため、フランジ３の楔孔３ａに上方より挿入片１６を挿入する際にその挿入が容易となる。   FIG. 3 (a) shows that the insertion piece 13 of the locking member 8 is inserted into the wedge hole 3a of the flange 3 when the wife-side leading handrail 1 is installed between the inner and outer support columns 2 and 2 facing in the width direction of the scaffolding plate. Indicates the state. The insertion piece 13 has a tapered lower portion of the large-diameter shaft portion 13b to form a tapered insertion guide portion 13bo. Therefore, when the insertion piece 16 is inserted into the wedge hole 3a of the flange 3 from above, the insertion piece 13 is inserted. Becomes easy.

図３の(b) は上記挿入片１３の作用を示したもので、作業者が、自分の身に付けた安全帯（図示せず）を妻側先行手摺り１の水平材５につないで作業を行っている時に足を滑らせるなどして足場板４から墜落状態となり、その安全帯を介して水平材５に下向きの衝撃荷重Ｐが負荷されると、同図の仮想線で示すように水平材５が撓んで水平材５の端部が水平方向Ｈに変位し、それにより挿入片１３の係止段部１４が同図実線図示のようにフランジ３の楔孔３ａの周縁３ａｏに係止して、楔孔３ａからの挿入片１６の抜け出しを阻止し、それにより妻側安全手摺り１が支柱２から外れなくなって、作業者の墜落が防止されることになる。   FIG. 3 (b) shows the operation of the insertion piece 13. An operator connects a safety belt (not shown) worn on his / her body to the horizontal member 5 of the front handrail 1 on the wife side. If the platform plate 4 falls from the scaffolding plate 4 by sliding the foot while working, and a downward impact load P is applied to the horizontal member 5 through the safety belt, as shown by the phantom line in FIG. Then, the horizontal member 5 is bent and the end of the horizontal member 5 is displaced in the horizontal direction H, so that the locking step 14 of the insertion piece 13 is moved to the peripheral edge 3ao of the wedge hole 3a of the flange 3 as shown by the solid line in FIG. The locking prevents the insertion piece 16 from coming out of the wedge hole 3a, thereby preventing the wife-side safety handrail 1 from coming off the support column 2 and preventing the operator from falling.

上記係止部材８の挿入片１３を板状本体１２に取り付けるには、図２の(b) 及び(c) に一例を示すように、板状本体１２の先端側に挿入片１３の径小軸部１３ａを嵌め込み可能な開口部１２ｏを形成して、これに径小軸部１３ａの上部側を嵌め込み、この嵌め込んだ一径小軸部１３ａを板状本体１２の開口部１２ｏ部分に溶接して固着すればよい。   In order to attach the insertion piece 13 of the locking member 8 to the plate-like main body 12, the diameter of the insertion piece 13 is small at the distal end side of the plate-like main body 12, as shown in FIG. 2 (b) and (c). An opening 12o into which the shaft portion 13a can be fitted is formed, and the upper side of the small-diameter shaft portion 13a is fitted into this, and the fitted small-diameter small shaft portion 13a is welded to the opening 12o portion of the plate-like main body 12. And then stick.

係止フック９は、図４の(a) ，(b) に示すように、各斜材６，７の他端部（下端部）に取付部片１６を介して取り付け固定され、支柱２，２間に横架される横ステー１０に対し上方より嵌脱自在に係止されるフック本体１７と、横ステー１０に掛合してフック本体１７の上方への移動を阻止するロック部材（一般には落下錠と称される）１８とからなり、ロック部材１８は、上下２箇所の長孔ａ，ｂに夫々通されてフック本体１４ａに固定されたピン１９，２０により、図４の(b) に示すようなロック位置と、図示位置から上方へスライドしたロック解除位置との間でスライド自在に取り付けられ、常時は自重によって図示のようなロック位置に保持されている。   As shown in FIGS. 4A and 4B, the locking hook 9 is attached and fixed to the other end portions (lower end portions) of the diagonal members 6 and 7 via attachment portion pieces 16. A hook body 17 that is removably engaged with the horizontal stay 10 that is horizontally mounted between the two, and a lock member that engages the horizontal stay 10 and prevents the hook body 17 from moving upward (generally, 4 (refer to FIG. 4 (b)). The lock member 18 is passed through the two long holes a and b at the upper and lower portions and fixed to the hook body 14a by pins 19 and 20, respectively. Is slidably mounted between a lock position as shown in FIG. 5 and a lock release position slid upward from the illustrated position, and is normally held at the locked position as shown by its own weight.

従って、係止フック９を横ステー１０に係止させる時は、ロック位置に保持されているロック部材１８を作業者が手でロック解除位置へ引き上げてロック解除状態で横ステー１０に係止させればよく、そしてロック部材１８から手を離せば、ロック部材１８が自重によりロック位置へスライドして、自動的にロック位置に保持される。   Therefore, when the locking hook 9 is locked to the lateral stay 10, the operator pulls the lock member 18 held at the locked position to the unlocked position by hand and locks it to the horizontal stay 10 in the unlocked state. If the hand is released from the lock member 18, the lock member 18 slides to the lock position by its own weight and is automatically held at the lock position.

横ステー１０の両端部は、夫々固定金具２２を介して、足場板幅方向に対向する支柱２，２のフランジ３，３に固定される。この固定金具２２は、図５の(a) ，(b) に示すように、支柱２のフランジ３に跨嵌されるように側面視略コ字状に形成されて、その先端側上下部に楔孔２３ａ，２３ｂを有し、基端部が横ステー１０の端部に固着された固定シュー２３と、この固定シュー２３の楔孔２３ａ，２３ｂとフランジ３の楔孔３ａとにわたって挿着される楔２４とからなる。   Both end portions of the lateral stay 10 are fixed to the flanges 3 and 3 of the support columns 2 and 2 facing each other in the scaffolding plate width direction through fixing brackets 22 respectively. As shown in FIGS. 5 (a) and 5 (b), the fixing bracket 22 is formed in a substantially U shape in a side view so as to straddle the flange 3 of the column 2, and is formed at the top and bottom of the tip side. A fixed shoe 23 having wedge holes 23a and 23b, the base end of which is fixed to the end of the lateral stay 10, and the wedge holes 23a and 23b of the fixed shoe 23 and the wedge holes 3a of the flange 3 are inserted and attached. And wedge 24.

上記固定金具２２の取付けにあたっては、図５の(a) ，(b) に示すように、固定シュー２３を支柱２のフランジ３に跨嵌して、楔２４を固定シュー２３の上部及び下部楔孔２３ａ，２３ｂとフランジ３の楔孔３ａとに挿入して、ハンマーで打ち込めばよい。尚、各楔２４の下端部には***部２４ａが形成されていて、楔２４を上方に引き出している時は、***部２４ａが肉厚であるから、固定シュー２３の上部楔孔２３ａから抜け出ないようにし、これによって楔２４の紛失う防ぐことができる。この場合、下部楔孔２３ｂは上部楔孔２３ａよりも幅広に形成され（図５の(b) 参照）、***部２４ａに支障を受けることなく、下部楔孔２３ｂを通過して下方まで打ち込むことができるようになっている。   When the fixing bracket 22 is attached, as shown in FIGS. 5A and 5B, the fixing shoe 23 is straddled over the flange 3 of the column 2 and the wedge 24 is connected to the upper and lower wedges of the fixing shoe 23. What is necessary is just to insert in hole 23a, 23b and the wedge hole 3a of the flange 3, and drive it with a hammer. A raised portion 24a is formed at the lower end of each wedge 24. When the wedge 24 is pulled upward, the raised portion 24a is thick, so that it protrudes from the upper wedge hole 23a of the fixed shoe 23. This prevents the wedge 24 from being lost. In this case, the lower wedge hole 23b is formed wider than the upper wedge hole 23a (see (b) of FIG. 5), and is driven downward through the lower wedge hole 23b without being hindered by the raised portion 24a. Can be done.

上記のような構成よりなる妻側先行手摺り１の使用について説明すると、この妻側先行手摺り１は、楔緊結式の足場を仮設するにあたり、既設の下段側足場板４から新設される上段側足場板４の先行手摺りとして、仮設足場の足場板幅方向に対向する支柱２，２間に取り付けるものであるが、先ず、内外支柱２，２間において１段目足場板４の仮設高さに対応する位置に横ステー１０を横架し、この横ステー１０に両斜材６，７の下端部の係止フック９，９が係止できるように水平材５の両端部の係止部材８，８を内外支柱２，２の所要高さ位置にあるフランジ３，３に夫々係止し、しかして両斜材６，７を交差させた状態で、両斜材６，７の下端部の係止フック９，９を前記横ステー１０に係止することにより、妻側先行手摺り１を取り付ける。   The use of the wife-side leading handrail 1 having the above-described configuration will be described. The wife-side leading handrail 1 is an upper stage newly provided from the existing lower-stage scaffolding plate 4 when temporarily installing a wedge-tightening type scaffold. As the preceding handrail of the side scaffolding plate 4, it is attached between the struts 2 and 2 facing the scaffolding plate width direction of the temporary scaffolding. First, the temporary height of the first stage scaffolding plate 4 between the inner and outer struts 2 and 2. The horizontal stay 10 is horizontally mounted at a position corresponding to the height, and the horizontal stay 5 is locked at both ends of the horizontal member 5 so that the locking hooks 9, 9 at the lower ends of the diagonal members 6, 7 can be locked. The members 8 and 8 are respectively engaged with the flanges 3 and 3 at the required height positions of the inner and outer supports 2 and 2, and the lower ends of the diagonal members 6 and 7 are crossed. By attaching the hooks 9 and 9 to the horizontal stay 10, the wife-side handrail 1 is attached. That.

係止部材８の取付けにおいては、作業者が一方の斜材６を垂直に立ち上げて、この斜材６の上端部側にある係止部材８の挿入片１６を、一方側の支柱２の所要のフランジ３の楔孔３ａに上方より挿入した後、他方の斜材７を同様に立ち上げて、水平材５を水平姿勢に保持した状態で、この斜材７の上端部にある係止部材８の挿入片１６を反対側の支柱２の所要のフランジ３の楔孔３ａに挿入すればよい。   In attaching the locking member 8, an operator raises one diagonal member 6 vertically and inserts the insertion piece 16 of the locking member 8 on the upper end side of the diagonal member 6 into the column 2 on one side. After being inserted into the wedge hole 3a of the required flange 3 from above, the other diagonal member 7 is similarly raised, and the horizontal member 5 is held in a horizontal posture, and the latching at the upper end of the diagonal member 7 is held. What is necessary is just to insert the insertion piece 16 of the member 8 in the wedge hole 3a of the required flange 3 of the support | pillar 2 on the opposite side.

上記のようにして１段目足場の妻側端部となる妻側先行手摺り１を取り付けたならば、この１段目の足場の対向する横ステー１０，１０間に１段目足場板４をその両端部にあるフック４ａ，４ａを介して掛架する。こうして掛架した１段目足場板４の上に作業者が乗って、内外支柱２の継ぎ足しを行うと共に、その継ぎ足した内外支柱２，２間には２段目足場板４の仮設高さに対応する位置に横ステー１０を横架する。この支柱２の継ぎ足し作業や横ステー１０の横架作業時には、１段目足場の妻側端部に妻側先行手摺り１が先行して取り付けられているため、作業者は、この妻側先行手摺り１によって作業を安全に行うことができる。   If the wife-side leading handrail 1 that becomes the wife-side end portion of the first-stage scaffold is attached as described above, the first-stage scaffold plate 4 is placed between the opposing lateral stays 10, 10 of the first-stage scaffold. Is suspended via hooks 4a, 4a at both ends thereof. An operator rides on the suspended first stage scaffolding plate 4 to add the inner and outer struts 2, and the temporary height of the second stage scaffolding plate 4 is between the added inner and outer struts 2 and 2. The horizontal stay 10 is placed horizontally at the corresponding position. When the post 2 is added or the horizontal stay 10 is installed horizontally, the wife-side leading handrail 1 is attached in advance to the end of the wife on the first-stage scaffolding. Work can be performed safely by the handrail 1.
