Description

本発明は、仮設用足場の足場板の周囲に取り付けて作業安全を確保する足場用幅木に関する。   [Technical Field] The present invention relates to a scaffolding baseboard that is attached to the periphery of a scaffolding plate of a temporary scaffolding to ensure work safety.

従来より、建枠及び足場板を組み上げて構築する仮設用足場の足場板の周囲には、作業者の墜落防止などの作業安全を確保するために足場用の幅木が取り付けられている。前記幅木としては、例えば、実公平５−２８２７８号公報に示されるように、幅木本体の両端部に略Ｕ字形状の係止金具を備え、この係止金具を建枠の脚柱へ係止固定するようにしたものがある。
実公平５−２８２７８号 Conventionally, scaffolding skirting boards are attached around a scaffolding board of a temporary scaffolding constructed by assembling a building frame and a scaffolding board in order to ensure work safety such as prevention of a worker from falling. As the skirting board, for example, as shown in Japanese Utility Model Publication No. 5-28278, both ends of the skirting board body are provided with substantially U-shaped locking brackets, and the locking brackets are used as pedestals of the building frame. There is something that is fixed and locked.
No. 5-28278

しかしながら、実公平５−２８２７８号公報に示される従来の幅木では、幅木本体を建枠の脚柱に対して取り付ける構成としているため、どうしても足場板の側縁には隙間が生じる。そして、何かの拍子で足場板が横へずれ動いて建枠の一方側へと偏ってしまった場合などには、その隙間が大きくなって作業安全が十分に確保できないおそれがある。   However, in the conventional baseboard shown in Japanese Utility Model Publication No. 5-28278, the baseboard body is attached to the pedestal of the building frame, so a gap is inevitably generated on the side edge of the scaffolding board. If the scaffolding plate is shifted to the side by some time and is biased to one side of the building frame, there is a possibility that the gap becomes large and the work safety cannot be sufficiently secured.

本発明は上記の点に鑑み、足場板の側縁に隙間を生じさせず、作業安全性の高い足場用幅木を提供することを課題とする。   This invention makes it a subject to provide the baseboard for scaffolding which does not produce a clearance gap in the side edge of a scaffold board, and has high work safety in view of said point.

And a generally L-shaped retaining bracket that pivots to prevent the retaining bracket from being pivoted, and the retaining bracket is biased to a latching position by a spring body, while both ends of the base plate body are The upper end of the frame is equipped with fixing brackets that fix it to the pedestal of the building frame. If this skirting board is attached to the scaffolding board, there will be no gap between the scaffolding board and the skirting board. Can be secured. In addition, since the locking metal fitting is prevented from being removed by the retaining metal fitting, work safety can be ensured more reliably.

また、請求項２記載の足場用幅木によれば、前記固定金具は、建枠の脚柱に引っ掛けて固定する略Ｊ字形状のフック金具であり、該フック金具はその基端軸部を幅木本体の長手方向と並行に配して回動自在に軸着し、かつ幅木本体の長手方向へ進退自在としてバネ体によって幅木本体の内方へ付勢させてなるので、設置作業がごく簡単で済み、高所作業に好適である。   According to the scaffolding skirting board of claim 2, the fixing metal fitting is a substantially J-shaped hook metal fitting that is hooked and fixed to a pedestal of a building frame, and the hook metal fitting has a base end shaft portion thereof. Installation work because it is arranged parallel to the longitudinal direction of the skirting board and pivotally mounted, and is urged inward by the spring body so that it can advance and retreat in the longitudinal direction of the skirting board. Is very simple and suitable for high-altitude work.

本発明に係る請求項１記載の足場用幅木によれば、幅木の下端部を足場板の係止クランプに係止して幅木と足場板とを一体化するものであり、幅木本体の両端側面の下端部に足場板の係止クランプへ上方より差し込んで係止させる略逆Ｕ字形状の係止金具と、足場板の係止クランプの下端縁に下端部に形成したかぎ爪部を掛け止めて前記係止金具の上方への動きを阻止することにより係止金具の抜け止めを図るようにした略レ字形状の抜け止め金具とを回動自在に軸着している。また、前記抜け止め金具は、バネ体によって掛け止め位置、即ち抜け止め金具の下端部に形成したかぎ爪部が係止クランプの下端縁に当接して掛け止められる位置へと付勢させている。また、幅木本体の両端の上端部には建枠の脚柱に固定する固定金具を備えている。   According to the baseboard for scaffolding according to claim 1 of the present invention, the baseboard and the scaffolding board are integrated by locking the lower end of the baseboard to the locking clamp of the scaffolding board, A substantially inverted U-shaped locking bracket that is inserted and locked to the lower end of the both side surfaces of the scaffolding plate from above, and a claw portion formed at the lower end of the lower end edge of the locking clamp of the scaffolding plate A generally L-shaped retaining metal fitting that is adapted to prevent the retaining member from coming off by latching the retaining member to prevent the upward movement of the retaining member is pivotally mounted. Further, the retaining bracket is biased by a spring body to a latching position, that is, a position where a claw portion formed at the lower end portion of the retaining bracket comes into contact with the lower end edge of the locking clamp and is latched. . Moreover, the upper end part of the both ends of a skirting board main body is equipped with the fixture which fixes to the pedestal of a building frame.

そして、幅木を取り付けるときには、前記係止金具を足場板の係止クランプへ上方から差し込んで係止させる。このとき、抜け止め金具のかぎ爪部がバネ体の付勢力によって自動的に足場板の係止クランプの下端縁に掛け止められ、係止金具が抜け外れたりしないように確実に固定し、幅木本体の下端縁を足場板上面と近接または当接させて幅木と足場板の一体化を図っている。次いで、これら係止金具を支点に幅木本体を建枠の脚柱側へ回動させ、幅木本体の上端縁が脚柱と近接または当接するまで傾倒させた後、幅木本体の上端部に備えた固定金具を建枠の脚柱に固定して幅木の設置を完了する。   And when attaching a skirting board, the said locking metal fitting is inserted and locked from the upper part to the locking clamp of a scaffold board. At this time, the claw portion of the retaining bracket is automatically latched to the lower edge of the locking clamp of the scaffolding plate by the urging force of the spring body, and is securely fixed so that the retaining bracket does not come off. The base board and the scaffolding board are integrated by bringing the lower end edge of the wooden body into close proximity or contact with the upper surface of the scaffolding board. Next, the skirting board main body is turned to the pedestal side of the building frame with these locking brackets as a fulcrum, and tilted until the upper edge of the skirting board approaches or comes into contact with the pedestal, and then the upper end of the skirting board main body. The installation of the skirting is completed by fixing the fixing brackets prepared for to the pedestal of the building frame.

このように、幅木の下端部を足場板の係止クランプに係止させて足場板の側縁に立設しているので、従来のように足場板の側縁に隙間が生じることもなく、また何かの拍子で足場板が左右にずれ動いたとしても足場と幅木が一体となって動くのでやはり隙間を生じることはなく、作業安全性が確保される。また、抜け止め金具で係止金具の抜け止めが図られているので、作業時などに何かの拍子で係止金具が抜け外れてしまうようなおそれもなく、より確実に作業安全性を確保できる。   In this way, because the lower end of the baseboard is locked to the locking clamp of the scaffolding plate and is erected on the side edge of the scaffolding plate, there is no gap in the side edge of the scaffolding plate as in the past, Also, even if the scaffolding plate moves to the left or right due to any beat, the scaffolding and skirting board move together, so there is no gap, and work safety is ensured. In addition, since the locking bracket is secured with the retaining bracket, there is no risk that the locking bracket will come off due to any moment during work, etc., ensuring work safety more reliably. it can.

また、請求項２記載の足場用幅木によれば、固定金具として、幅木本体の両端の上端部には建枠の脚柱に引っ掛けて固定する略Ｊ字形状のフック金具を備え、該フック金具はその基端軸部を幅木本体の長手方向と並行に配して回動自在に軸着し、かつ幅木本体の長手方向へ進退自在としてバネ体によって幅木本体の内方へ付勢させるようにしている。   Further, according to the scaffolding skirting board according to claim 2, as the fixing bracket, the upper end portion of both ends of the baseboard body is provided with a substantially J-shaped hook bracket that is hooked and fixed to the pedestal of the building frame, The hook metal fitting is pivotally mounted with its base end shaft parallel to the longitudinal direction of the skirting board body, and it can be moved back and forth in the longitudinal direction of the skirting board body so that it can be moved back and forth inward of the skirting board body I try to energize it.

そして、幅木を建枠の脚柱に固定するときには、幅木本体の両端の上端部に備えた略Ｊ字形状のフック金具をバネ体の付勢力に抗して幅木本体の側方へ引っ張り、フック部が略水平となるように回動させて調節した後、フック金具を離してバネ体の復元力によってフック部を建枠の脚柱に引っ掛けて固定を完了する。   When fixing the skirting board to the pedestal of the building frame, the substantially J-shaped hook fittings provided at the upper ends of the both ends of the skirting board body are moved to the side of the skirting board body against the urging force of the spring body. After pulling and rotating and adjusting the hook portion to be substantially horizontal, the hook fitting is released and the hook portion is hooked on the pedestal of the building frame by the restoring force of the spring body to complete the fixing.

このように、ごく簡単な操作にて幅木を立設状態で固定することができ、高所作業に対して好適である。   In this way, the skirting board can be fixed in an upright state by a very simple operation, which is suitable for high-altitude work.

以下、本発明の実施例を図面に基づいて説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１及び図２は建築現場などで複数の建枠Ａを所定間隔にて立設し、隣接する建枠Ａの横架材Ａａ間に足場板Ｂを、また建枠Ａの脚柱Ａｂ間に筋交いＣを掛け止めてなる仮設用足場を示しており、前記足場板Ｂの周囲には本発明の足場用幅木１を取り付けている。図３乃至図５はその要部拡大図であって、前記幅木１は足場板Ｂと略同一長さの軽量溝形鋼部材からなる幅木本体２を主体とし、該幅木本体２の両端側面２ａの下端部に足場板Ｂの係止クランプＢａへ係止させる係止金具３と、係止金具３の抜け止めを図る抜け止め金具４とをそれぞれ備えていると共に、幅木本体２の両端側面２ａの上端部には建枠Ａの脚柱Ａｂに固定する固定金具であるフック金具５を備えている。   1 and 2 show that a plurality of building frames A are erected at a predetermined interval at a construction site or the like, a scaffolding plate B is provided between the horizontal members Aa of the adjacent building frames A, and between the pillars Ab of the building frame A 1 shows a temporary scaffold formed by hooking a brace C, and a scaffolding skirting board 1 of the present invention is attached around the scaffold plate B. FIG. 3 to FIG. 5 are enlarged views of the main part, and the skirting board 1 is mainly composed of a skirting board main body 2 made of a lightweight channel steel member having substantially the same length as the scaffolding board B. The lower end of each side face 2a is provided with a locking fitting 3 for locking to the locking clamp Ba of the scaffolding plate B, and a retaining fitting 4 for preventing the locking fitting 3 from coming off. A hook metal fitting 5 which is a fixing metal fitting fixed to the pedestal pillar Ab of the building frame A is provided at the upper ends of both side surfaces 2a.

前記係止金具３は、所定幅のスリット６を有する略逆Ｕ字形状の板状金具であり、幅木本体２の両端側面２ａと平行に配置し、その上端部を軸体７にて幅木本体２の両端側面２ａの下端部に回動自在に軸着している。ここで、前記スリット６は足場板Ｂの係止クランプＢａの厚みよりも若干幅広に形成しており、図５及び図６に示すように、このスリット６を係止クランプＢａの基端部位置へ上方より差し込んで係止できるようにしている。   The locking metal fitting 3 is a substantially inverted U-shaped plate-like metal fitting having a slit 6 of a predetermined width, and is arranged in parallel with both side surfaces 2 a of the baseboard body 2, and the upper end of the metal fitting 3 is widened by the shaft body 7. The wood main body 2 is pivotally attached to the lower end portions of both side surfaces 2a. Here, the slit 6 is formed to be slightly wider than the thickness of the locking clamp Ba of the scaffold plate B, and as shown in FIGS. 5 and 6, the slit 6 is located at the base end portion position of the locking clamp Ba. It can be inserted and locked from above.

前記抜け止め金具４は、略レ字形状に形成した金具であり、その下端部には足場板Ｂの係止クランプＢａの下端縁に引っ掛けて掛け止められるようにかぎ爪部４ａを形成している。そして、この抜け止め金具４も前記係止金具３と同様に、幅木本体２の両端側面２ａと平行に配置し、その上端部を前記係止金具３を軸着する軸体７にて回動自在に軸着している。したがって、係止金具３と抜け止め金具４とは、図に示すように、平行に近接した状態で一つの軸体７にて同軸に軸着されている。   The retainer bracket 4 is a bracket formed in a substantially letter shape, and a claw portion 4a is formed on the lower end portion thereof so as to be hooked and latched on the lower end edge of the locking clamp Ba of the scaffold plate B. Yes. Similarly to the locking metal fitting 3, the retaining metal fitting 4 is also arranged in parallel with both side surfaces 2a of the skirting board body 2, and the upper end thereof is rotated by a shaft body 7 on which the locking metal fitting 3 is attached. It is pivotally attached. Therefore, as shown in the drawing, the locking metal fitting 3 and the retaining metal fitting 4 are coaxially attached to one shaft body 7 in a state of being close to each other in parallel.

また、抜け止め金具４は、その上端部と軸体７とにわたって取り付けたバネ体８によって掛け止め位置、即ち図５の実線で示す位置へ付勢させており、前記係止金具３のスリット６を係止クランプＢａの基端部へ上方から差し込んで係止させる際には、図５に示すように、抜け止め金具４の下端部はバネ体８の付勢力に抗して一旦拡開して係止クランプＢａとの干渉を回避した後、係止クランプＢａの基端部がスリット６に収まる位置まで来ると、抜け止め金具４の下端部はバネ体８の復元力によって元の位置に戻り、このとき抜け止め金具４の下端部に形成したかぎ爪部４ａが係止クランプＢａの下端縁に引っ掛かって掛け止められる構造としている。なお、この抜け止め金具４のかぎ爪部４ａによる係止クランプＢａへの掛け止めを解除する場合には、抜け止め金具４の上端片を指でつまんでバネ体８の付勢力に抗して少し回動させてやれば容易に解除することができる。   Further, the retaining bracket 4 is biased to a latching position, that is, a position indicated by a solid line in FIG. Is inserted into the base end portion of the locking clamp Ba from above and locked, the lower end portion of the retaining metal fitting 4 is once expanded against the urging force of the spring body 8 as shown in FIG. After avoiding interference with the locking clamp Ba, when the base end of the locking clamp Ba reaches a position where it can be accommodated in the slit 6, the lower end of the retaining metal fitting 4 is returned to its original position by the restoring force of the spring body 8. At this time, the claw portion 4a formed on the lower end portion of the retaining metal fitting 4 is hooked on the lower end edge of the locking clamp Ba and latched. In addition, when releasing the latch to the locking clamp Ba by the claw portion 4a of the retaining bracket 4, the upper end piece of the retaining bracket 4 is pinched with a finger against the urging force of the spring body 8. It can be easily released by turning it a little.

このように、抜け止め金具４のかぎ爪部４ａを係止クランプＢａの下端縁に掛け止めれば、係止金具３の上方への動きを阻止でき、係止金具３の抜け外れを確実に防ぐことができる。こうして、係止金具３を足場板Ｂの係止クランプＢａに係止固定すれば、図５に示すように、幅木本体２は軸体７を支点として脚柱Ａｂ側に回動できるようになる。   Thus, if the hook 4a of the retaining metal fitting 4 is hooked on the lower end edge of the locking clamp Ba, the upward movement of the locking metal fitting 3 can be prevented, and the locking metal fitting 3 is surely prevented from coming off. be able to. Thus, if the locking metal fitting 3 is locked and fixed to the locking clamp Ba of the scaffold plate B, as shown in FIG. 5, the skirting board main body 2 can turn to the pedestal Ab side with the shaft body 7 as a fulcrum. Become.

一方、前記フック金具５は、建枠Ａの脚柱Ａｂに引っ掛けて固定可能なように略Ｊ字形状に折曲形成した棒状金具であり、幅木本体２の両端に備え、その円弧状のフック部９を幅木本体２の長手方向側方に突出させていると共に、直線状の基端軸部１０を幅木本体２の長手方向と並行に配して図３及び図４中の矢印方向へ進退自在とし、かつ基端軸部１０にはバネ体１１を外装して幅木本体２の内方へ付勢させている。そして、前記フック部９を脚柱Ａｂに引っ掛けさえすれば、バネ体１１の復元力によって幅木本体２は強固に固定される。このように、高所作業に適した簡単な操作でありながら確実に固定可能としていると共に、取り付け用の工具なども必要とせず、設置作業性に優れたものとしている。   On the other hand, the hook metal fitting 5 is a rod-like metal fitting bent into a substantially J shape so that it can be hooked and fixed on the leg pillar Ab of the building frame A, and is provided at both ends of the baseboard body 2 and has an arc shape. The hook portion 9 is protruded laterally in the longitudinal direction of the skirting board main body 2, and the straight base shaft portion 10 is arranged in parallel with the longitudinal direction of the skirting board main body 2 so that the arrows in FIGS. The base end shaft portion 10 is externally provided with a spring body 11 and is urged inward of the skirting board main body 2. And if only the said hook part 9 is hooked on the leg pillar Ab, the baseboard main body 2 will be firmly fixed by the restoring force of the spring body 11. FIG. In this way, while being a simple operation suitable for high-altitude work, it can be securely fixed, and it does not require an installation tool or the like, and is excellent in installation workability.

また、このフック金具５は、基端軸部１０を幅木本体２に対して回動自在に軸着しており、図５に示すように、幅木本体２の傾斜角度が変化してもフック金具５を常に水平に位置させることができ、建枠Ａの脚柱Ａｂに確実に引っ掛けて固定できるようにしている。なお、フック金具５は幅木本体２の左右によって、図３に示すように、それぞれその途中を上下逆向きに若干湾曲させており、仮設用足場に連続して幅木１を取り付けた際に、各幅木１のフック金具５同士が干渉しないように図っている。   Further, the hook metal fitting 5 has a base end shaft portion 10 pivotally attached to the skirting board body 2 so that the inclination angle of the skirting board body 2 changes as shown in FIG. The hook metal fitting 5 can always be positioned horizontally so that it can be securely hooked and fixed to the pedestal Ab of the building frame A. As shown in FIG. 3, the hook metal fitting 5 is slightly curved in the upside down direction depending on the left and right sides of the baseboard body 2, and when the baseboard 1 is attached continuously to the temporary scaffolding, The hook metal fittings 5 of the baseboards 1 are designed not to interfere with each other.

しかして、上記足場用幅木１を取り付けるときには、足場板Ｂ両端の各係止クランプＢａの基端部に幅木１両端の各係止金具３のスリット６を上方よりそれぞれ差し込んで係止させる。このとき、同時に抜け止め金具４下端部のかぎ爪部４ａが係止クランプＢａ基端部の下端縁に引っ掛かって掛け止められ、足場用幅木１と足場板Ｂの係止クランプＢａとは強固に固定される。次に、係止金具３の軸体７を支点に幅木本体２を脚柱Ａｂ側へ回動させ、幅木本体２の上端縁が脚柱Ａｂ側面と近接または当接するまで傾倒させる。続いて、フック金具５をバネ体１１の付勢力に抗して幅木本体２の側方へ引っ張った後、フック部９が略水平位置となるまで回動させてフック部９の開口部を脚柱Ａｂに対向させる。そして、その状態からフック金具５を離すと、バネ体１１の復元力によってフック金具５が幅木本体２の内方へ短縮していき、フック部９が脚柱Ａｂに引っ掛かって固定される。   Thus, when the scaffolding skirting board 1 is attached, the slits 6 of the respective locking metal fittings 3 at both ends of the baseboard 1 are inserted into the base end portions of the respective locking clamps Ba at both ends of the scaffolding board B from above to be locked. . At this time, the claw portion 4a at the lower end portion of the retaining metal fitting 4 is hooked on the lower end edge of the base end portion of the locking clamp Ba so that the scaffolding skirting board 1 and the locking clamp Ba of the scaffolding plate B are firmly connected. Fixed to. Next, the skirting board main body 2 is turned to the side of the pedestal Ab with the shaft body 7 of the locking metal fitting 3 as a fulcrum, and is tilted until the upper end edge of the skirting board main body 2 approaches or contacts the side surface of the pedestal Ab. Subsequently, after pulling the hook metal fitting 5 against the urging force of the spring body 11 to the side of the skirting board body 2, the hook part 9 is rotated until the hook part 9 is in a substantially horizontal position to open the opening of the hook part 9. It is made to oppose the pedestal Ab. Then, when the hook metal fitting 5 is released from the state, the hook metal fitting 5 is shortened inward of the skirting board main body 2 by the restoring force of the spring body 11, and the hook portion 9 is hooked on the pedestal Ab and fixed.

このように、幅木１は、その下端部を足場板Ｂの係止クランプＢａに係止して足場板Ｂの側縁に立設するものであるので、足場板Ｂの側縁に隙間が生じることもなく、また足場板Ｂと幅木１が一体となっているので足場板Ｂが左右にずれにくく、例え何かの拍子に左右にずれ動いたとしても、足場板Ｂと一体となって幅木１も動き、足場板Ｂの側縁に隙間を生じることもなく、安全性が確保される。また、抜け止め金具４によって幅木１と足場板Ｂの係止クランプＢａとは強固に固定されており、作業時などに幅木１に強い衝撃が加わったとしても外れて脱落するようなおそれはない。更に、幅木１を設置する作業も上記の通り簡単なものであるので、高所作業に適しており、また装置構造もごくシンプルなものであるので、製造コストを抑えることができると共に、メンテナンス面でも有利である。   In this way, the skirting board 1 has its lower end engaged with the locking clamp Ba of the scaffolding plate B and is erected on the side edge of the scaffolding plate B, so that there is a gap at the side edge of the scaffolding plate B. It does not occur, and the scaffold board B and the baseboard 1 are integrated, so the scaffold board B is not easily shifted to the left and right, and even if it moves to the left or right at any time, it is integrated with the scaffold board B. Thus, the skirting board 1 also moves and no gap is formed in the side edge of the scaffold board B, so that safety is ensured. Further, the base metal 1 and the locking clamp Ba of the scaffolding board B are firmly fixed by the retaining metal fittings 4, and even if a strong impact is applied to the base board 1 during work, there is a risk that it will come off and fall off. Absent. Furthermore, since the operation of installing the skirting board 1 is simple as described above, it is suitable for work at a high place and the structure of the apparatus is very simple, so that the manufacturing cost can be reduced and maintenance can be performed. This is also advantageous.
