Description

本発明は、建設作業現場などで用いられる仮設足場において、一定間隔ごとに設けられた互いに対向する足場用建枠の水平材の間に架け渡される足場板に関する。 The present invention relates to a scaffold plate that is spanned between horizontal members of a building frame for a scaffold that are provided at regular intervals and that are opposed to each other in a temporary scaffold used at a construction work site or the like.

建設作業現場などで用いられる仮設足場は、鋼管からなる複数本の支柱を桁行き方向（建築物の壁面に沿った方向）及びはり間方向（建築物の壁面に垂直な方向）に所定間隔をおいて配置し、桁行き方向に隣接する支柱に鋼管からなる水平材を取り付けた仮設足場用建枠を形成し、さらに、はり間方向に隣接する水平材の間に足場板を掛け渡して構成される。ここで支柱は、一定間隔ごとに、水平材等を固定するための取り付け部が設けられており、当該取り付け部に水平材を固定することによって仮設足場用建枠が組み上げられる。 Temporary scaffolds used at construction work sites, etc., have multiple columns of steel pipes spaced at predetermined intervals in the girder direction (direction along the wall surface of the building) and the beam direction (direction perpendicular to the wall surface of the building). The building frame for temporary scaffolding is formed by attaching horizontal members made of steel pipes to the struts adjacent to each other in the girder direction, and the scaffolding plate is spanned between the horizontal members adjacent to each other between the beams. Is done. Here, the support is provided with a mounting portion for fixing a horizontal member or the like at regular intervals, and the temporary scaffolding building frame is assembled by fixing the horizontal member to the mounting portion.

この仮設足場の足場板は、細長い平面長方形状の布枠に床板を取り付けた足場板本体と、足場板本体の両端に足場板本体から突出するように取り付けられるフック部材とを有している。この構成の足場板は、両端のフック部材を仮設足場の水平材に上から引っ掛けることで、隣接する水平材間に掛け渡されて固定される。 The scaffolding plate of the temporary scaffold has a scaffolding plate body in which a floor plate is attached to an elongated flat rectangular cloth frame, and hook members that are attached to both ends of the scaffolding plate body so as to protrude from the scaffolding plate body. The scaffold plate having this structure is fixed by being hooked between adjacent horizontal members by hooking hook members at both ends to the horizontal member of the temporary scaffold from above.

ところで、上記構成の足場板を足場枠組みに取り付けた場合、フック部材が足場板本体の端部から伸び出すようにして取り付けられているため、水平材と足場板本体との間に隙間が形成される。当該隙間から作業時に工具や建築部材等が落下する危険性がある。 By the way, when the scaffolding plate having the above configuration is attached to the scaffolding frame, the hook member is attached so as to extend from the end of the scaffolding plate main body, so that a gap is formed between the horizontal member and the scaffolding plate main body. The There is a risk that a tool, a building member, or the like may fall from the gap during work.

このため、例えば、特許文献１（特開２００８−４５３９８号公報）などにおいて、隣接する足場板間に隙間が発生しないように、足場板固定後から取り付けて当該隙間を塞ぐ専用の部材が開示されている。しかし、足場板とは別の部材であり、コスト高になることや後から取り付けることから作業性が悪い等の不具合があった。 For this reason, for example, Patent Document 1 (Japanese Patent Laid-Open No. 2008-45398) discloses a dedicated member that is attached after the scaffolding plate is fixed to close the gap so that no gap is generated between adjacent scaffolding plates. ing. However, since it is a member different from the scaffolding plate, there are problems such as high cost and poor workability because it is attached later.

また、この隙間閉塞部材の上記問題を解消するために、足場板本体に隙間埋めプレートを設けた足場板が種々知られている。例えば、特許文献２（特開２００１−１８２３１５号公報）や特許文献３（特開２００１−２１４６０８号公報）には、足場板本体の両端から突出した状態に配置されたフック部材の間に隙間埋めプレートを備え、当該隙間埋めプレートは平面視で水平材の略半分の位置まで伸びるように構成された足場板が記載されている。 In order to solve the above-mentioned problem of the gap closing member, various scaffold boards having a gap filling plate on the scaffold board main body are known. For example, in Patent Document 2 (Japanese Patent Laid-Open No. 2001-182315) and Patent Document 3 (Japanese Patent Laid-Open No. 2001-214608), a gap is filled between hook members arranged in a state of protruding from both ends of the scaffold plate body. A scaffolding plate is described that includes a plate, and that the gap filling plate is configured to extend to a position approximately half of the horizontal member in plan view.

また、特許文献４（特開２００５−９１２７号公報）には、足場板本体の両端から突出した状態に配置されたフック部材の間に、一端側にのみ隙間埋めプレートを備え、当該隙間埋めプレートは、平面視で水平材を完全に被覆するような長さに構成された足場板が記載されている。 Patent Document 4 (Japanese Patent Application Laid-Open No. 2005-9127) includes a gap filling plate only on one end side between hook members arranged in a state protruding from both ends of a scaffold plate body, and the gap filling plate. Describes a scaffolding plate configured to have a length that completely covers a horizontal member in plan view.

さらに、特許文献５（特開２００８−２３１８０４号公報）や特許文献６（意匠登録第１３８３１８８号公報）には、特許文献２及び特許文献３と同様に、平面視で水平材の略半分の位置まで伸びるように構成された隙間埋めプレートを備えた足場板が記載されており、当該隙間埋めプレートの形状として、側面視により平板状、三角形状などの種々の形状のものが記載されている。 Furthermore, in Patent Document 5 (Japanese Patent Laid-Open No. 2008-231804) and Patent Document 6 (Design Registration No. 1383188), as in Patent Document 2 and Patent Document 3, a position that is substantially half of the horizontal material in a plan view. Scaffolding plates provided with gap filling plates configured to extend to the maximum are described, and the shape of the gap filling plates is described in various shapes such as a flat plate shape and a triangular shape as viewed from the side.

しかし、上記特許文献の足場板はいずれも、隙間埋めプレートが平面視で水平材の上方に張り出すように配置されるため、隙間埋めプレートが支柱と水平材の連結機構や支柱自体等の仮設足場部材と干渉して使用時の組み立て作業性に問題が生じるという問題があった。 However, since all of the scaffolding plates in the above-mentioned patent documents are arranged so that the gap filling plate protrudes above the horizontal member in a plan view, the gap filling plate is temporarily installed such as a connecting mechanism between the column and the horizontal member or the column itself. There has been a problem in that the assembly workability at the time of use is problematic due to interference with the scaffold member.

また、特許文献２，３などの隙間埋めプレートは、板状のプレートが隣接する足場板の隙間埋めプレートとほぼ隙間なく配置可能な程度まで突出して構成されているため、高所への運搬などの取り扱い時に、隙間埋めプレートが引っかかり作業性が悪くなる等の問題があった。 In addition, the gap filling plates of Patent Documents 2 and 3 are configured so that the plate-like plate protrudes to the extent that it can be arranged with almost no gap from the gap filling plate of the adjacent scaffolding plate, so that it is transported to a high place, etc. During handling, there was a problem that the gap filling plate was caught and workability deteriorated.

したがって、本発明が解決しようとする技術的課題は、組み立て作業性が容易であり、運搬などの取り扱い作業性に優れた仮設足場用の足場板を提供することである。 Therefore, a technical problem to be solved by the present invention is to provide a scaffolding plate for a temporary scaffold that is easy to assemble and has excellent handling workability such as transportation.

And
A hook member provided so as to protrude from both ends of the scaffold plate main body and engageable with the horizontal member; and the scaffold plate main body provided so as to protrude from both ends of the scaffold plate main body between the hook members; A scaffold plate comprising a gap closing member that closes a gap formed between horizontal members,
The gap closing member is configured in a substantially triangular shape in a hollow view in cross section, including an upper surface portion extending in a direction along the upper surface of the scaffold plate body, and a lower surface portion extending from the top end of the upper surface portion to the end surface of the scaffold plate.
A scaffolding plate is provided, wherein a lower through-hole is formed at an intermediate position in the width direction of the lower surface portion.

本発明の第２態様によれば、さらに上面部の幅方向中間位置に上側貫通孔が形成されていることを特徴とする、第１態様の足場板を提供する。 According to the second aspect of the present invention, there is provided the scaffold plate according to the first aspect, wherein an upper through-hole is further formed at an intermediate position in the width direction of the upper surface portion.

FIG. 2 is a partially enlarged perspective view of the end portion of the scaffold plate in FIG. 3 is a partially enlarged perspective view of the end portion of the scaffold plate in FIG. 1 as viewed from the back side. The scaffold board according to the present embodiment is bridged between the horizontal members 102 of the temporary scaffold 100. As shown in FIG. 10, the temporary scaffold 100 is assembled along the periphery of the building. The temporary scaffold 100 is framed by a plurality of columns 101 erected in a plurality of rows at predetermined intervals along the outer periphery of the building and a horizontal member 102 constructed between the columns.

仮設足場１００は、図１０に示すように、フランジ１０３が設けられた支柱１０１を桁行き方向及びはり間方向に所定の間隔をおいて格子状に配置し、当該フランジ１０３に水平材１０２を固定することで組み上げられる。なお、足場板１が固定される水平材１０２は、はり間方向に隣接する支柱同士をつなぐように配置されるが、仮設足場用建枠の補強のために桁行き方向にも水平材１０２ａを架設してもよい。 As shown in FIG. 10, the temporary scaffold 100 is configured by arranging struts 101 provided with flanges 103 in a grid pattern at predetermined intervals in the direction of beam and the direction of beams, and fixing the horizontal member 102 to the flanges 103. It is assembled by doing. The horizontal member 102 to which the scaffolding plate 1 is fixed is arranged so as to connect the struts adjacent to each other in the beam-to-beam direction, but the horizontal member 102a is also provided in the girder direction in order to reinforce the temporary scaffolding building frame. It may be erected.

支柱１０１は、例えば、直径４５ｍｍ程度の金属パイプによって構成されており、長さ方向に複数本を連結して用いることができる。また、支柱１０１には、一定間隔ごと例えば、本実施形態では４５ｃｍごとに取り付け部の一例としてのフランジ１０３が設けられている。フランジ１０３は、複数の連結孔が設けられた板状の部材であり、水平材１０２の端部が当該フランジを挟んだ状態で配置され連結孔にくさびを挿入することで、水平材１０２と支柱１０１とが固定される。 The support column 101 is made of, for example, a metal pipe having a diameter of about 45 mm, and a plurality of the support columns 101 can be connected in the length direction. Moreover, the support | pillar 101 is provided with the flange 103 as an example of an attachment part for every fixed interval, for example, every 45 cm in this embodiment. The flange 103 is a plate-like member provided with a plurality of connecting holes, and the end of the horizontal member 102 is disposed with the flange interposed therebetween, and a wedge is inserted into the connecting hole, so that the horizontal member 102 and the support column are inserted. 101 is fixed.

足場板１は、図１に示すように、矩形に構成された足場板本体２と、足場板本体２の長手方向両端側に設けられた係止フック３と、係止フック３の間に配置された隙間閉塞部材４とが設けられている。 As shown in FIG. 1, the scaffolding plate 1 is disposed between a rectangular scaffolding plate main body 2, locking hooks 3 provided at both longitudinal ends of the scaffolding plate main body 2, and the locking hooks 3. The gap closing member 4 is provided.

足場板本体２は、一体成形で加工され、板状の部材をコの字状とした棒材が組み合わされて矩形状に構成された足場板本体２の外縁を構成する側フレーム５と、側フレーム５に固定された天板６とで構成されている。なお、本実施形態では、側フレーム５の横幅及び長さ寸法が大きいため、側フレーム５には長手方向に伸びる中央梁７及び幅方向梁（図示なし）を設けている。 The scaffold plate body 2 is processed by integral molding, and a side frame 5 that forms an outer edge of the scaffold plate body 2 that is formed into a rectangular shape by combining bar-shaped members with plate-shaped members, and a side The top plate 6 is fixed to the frame 5. In the present embodiment, since the lateral width and length of the side frame 5 are large, the side frame 5 is provided with a central beam 7 and a width direction beam (not shown) extending in the longitudinal direction.

天板６は、複数の貫通孔が設けられたパンチングメタルで構成されている。なお、天板６としては、メッシュ状のエキスパンドメタルを用いてもよい。 The top plate 6 is made of a punching metal provided with a plurality of through holes. In addition, as the top plate 6, a mesh-like expanded metal may be used.

側フレーム５の長手方向側両端に設けられている係止フック３は、図４に示すように、水平材１０２に係止して踏板を連結する。係止フック３は、足場板本体２の両端部の端面に基端側をリベットや溶接などで取り付けられている。 As shown in FIG. 4, the locking hooks 3 provided at both ends in the longitudinal direction of the side frame 5 are locked to the horizontal member 102 to connect the treads. The locking hook 3 is attached to the end surfaces of the both ends of the scaffold plate body 2 by rivets or welding on the base end side.

係止フック３は、水平材１０２に上から係合可能なＵ字状の係合溝８ａを先端部に有する板状の部材であるフック本体８と当該フック本体にスライド可能に設けられた落下防止ツメ９とを備えている。落下防止ツメ９は、図４に示すように、２つの長孔９ａを有しており、フック本体８に設けられた固定ピン１０によってフック本体８にスライド可能に設けられている。 The locking hook 3 includes a hook body 8 that is a plate-like member having a U-shaped engagement groove 8a that can be engaged with the horizontal member 102 from above, and a drop that is slidably provided on the hook body. And a prevention claw 9. As shown in FIG. 4, the fall prevention claw 9 has two long holes 9 a and is slidably provided on the hook body 8 by a fixing pin 10 provided on the hook body 8.

なお、本実施形態において、係止フック３は、足場板本体２の両端部端面２ａから係合溝８ａまでの距離が、フランジ１０３の支柱からの突出幅よりも長くなるように構成されている。 In the present embodiment, the locking hook 3 is configured such that the distance from the end surface 2a of both ends of the scaffold plate body 2 to the engaging groove 8a is longer than the protruding width of the flange 103 from the column. .

係合溝８ａは、その上端部分が、足場板本体２や天板６の上面と略同じ高さとなるように構成されており、足場板１を水平材１０２に係合させたとき、水平材１０２の上面が天板６と略同じ高さとなるように構成されている。 The engaging groove 8 a is configured such that the upper end portion thereof is substantially the same height as the upper surface of the scaffolding plate body 2 and the top plate 6, and when the scaffolding plate 1 is engaged with the horizontal member 102, the horizontal member The upper surface of 102 is configured to have substantially the same height as the top plate 6.

係止フック３を水平材１０２に係合させるときは、落下防止ツメ９を上側に移動させることにより、係止フック３の係合溝８ａの下側を開放させて、水平材１０２を上側から係止フック３の係合溝８ａに嵌入させ、その後落下防止ツメ９を下方向に移動させることで、水平材１０２の下側に係止防止ツメ９を配置させることで、吹き上げなどによる足場板１の落下を防止する。 When the locking hook 3 is engaged with the horizontal member 102, the lower prevention claw 9 is moved upward to open the lower side of the engaging groove 8a of the locking hook 3, and the horizontal member 102 is moved from the upper side. By placing the locking prevention claw 9 on the lower side of the horizontal member 102 by inserting it into the engagement groove 8a of the locking hook 3 and then moving the fall prevention claw 9 downward, a scaffolding plate by blowing up or the like Prevent the fall of 1.

足場板本体２の両端部に取り付けられている係止フック３は、双方で取り付け位置を若干ずらして取り付けられているため、複数の足場板１が水平材１０２の間に互いに長手方向に連続して掛け渡される場合に、双方の係止フックが互いに干渉しあうことがなく、また、係止フックの周囲に生じる隙間を極力なくすことができる。 Since the locking hooks 3 attached to both ends of the scaffolding plate body 2 are attached with their mounting positions slightly shifted from each other, the plurality of scaffolding plates 1 are continuous in the longitudinal direction between the horizontal members 102. When the two hooks are suspended, the two hooks do not interfere with each other, and the gap generated around the hooks can be minimized.

隙間閉塞部材４は、図２及び図３に示すように、足場板本体２の両端部端面２ａに溶接などの手段により固定される。隙間閉塞部材４は、１枚の金属板を略三角形状に折り曲げて構成され、足場板本体２の上面と略同じ高さで上面に沿って伸びるように設けられた上面部１１と、上面部１１に連続して設けられ、斜め方向に伸びる下面部１２とを備え、内部は中空に構成されている。なお、本実施形態では、下面部１２は、足場板本体２の両端部端面２ａに当接しているが、下面部１２の傾斜角度を異ならせて、側フレーム５の下端に当接するように構成してもよい。 As shown in FIGS. 2 and 3, the gap closing member 4 is fixed to both end portions 2 a of the scaffold plate body 2 by means such as welding. The gap closing member 4 is configured by bending a single metal plate into a substantially triangular shape, and is provided with an upper surface portion 11 provided to extend along the upper surface at substantially the same height as the upper surface of the scaffold plate body 2, and an upper surface portion 11 and a lower surface portion 12 extending in an oblique direction, and the inside is configured to be hollow. In the present embodiment, the lower surface portion 12 is in contact with the end surfaces 2a of both ends of the scaffold board body 2, but is configured to be in contact with the lower end of the side frame 5 by varying the inclination angle of the lower surface portion 12. May be.

また、上面部１１及び下面部１２には、それぞれ上側貫通孔１３，下側貫通孔１４が設けられている。図５、図６に示すように、上側貫通孔１３及び下側貫通孔１４は、それぞれ上面部１１及び下面部１２の幅方向中間部に設けられる。また、上側貫通孔１３及び下側貫通孔１４の幅方向寸法Ａ，Ｂは、特に制限されるものではない。 The upper surface portion 11 and the lower surface portion 12 are provided with an upper through hole 13 and a lower through hole 14, respectively. As shown in FIGS. 5 and 6, the upper through-hole 13 and the lower through-hole 14 are provided in the intermediate portions in the width direction of the upper surface portion 11 and the lower surface portion 12, respectively. Further, the width direction dimensions A and B of the upper through hole 13 and the lower through hole 14 are not particularly limited.

上側貫通孔１３は、落下防止のために幅方向寸法Ａを小さく構成することが好ましい。具体的には足場板１の幅方向寸法にもよるが、１から３ｃｍ程度であることが好ましい。 The upper through-hole 13 is preferably configured to have a small width-direction dimension A to prevent dropping. Specifically, although it depends on the width direction dimension of the scaffold plate 1, it is preferably about 1 to 3 cm.

下側貫通孔１４は、後述するフランジとの干渉防止のため、上側貫通孔１３の幅方向寸法Ａよりも大きくすることが好ましい。具体的には下面部１２の幅寸法の１０〜６０％程度の幅寸法とすることができる。 The lower through-hole 14 is preferably larger than the width direction dimension A of the upper through-hole 13 in order to prevent interference with a flange described later. Specifically, the width can be about 10 to 60% of the width of the lower surface portion 12.

上側貫通孔１３，下側貫通孔１４は、例えば、足場板１を吊り下げて高所に持ち上げる際に使用されるクレーンなどの吊り下げ部材を係止する場合に好適に使用することができる。すなわち、上側貫通孔１３は、足場板１の端部に設けられている隙間閉塞部材４の幅方向中央部に幅方向寸法Ａが小さく設けられているため、当該上側貫通孔１３に吊り下げ部材のフックなどを嵌合させて吊り下げた場合に、フックが上面部１１及び下面部１２の貫通孔周縁に接触するため吊り下げ姿勢が安定し、安全に足場板１を昇降させることができる。 The upper through-hole 13 and the lower through-hole 14 can be preferably used when, for example, a suspension member such as a crane used to suspend the scaffold plate 1 and lift it to a high place is locked. That is, since the upper side through-hole 13 is provided with a small width-direction dimension A at the center in the width direction of the gap closing member 4 provided at the end of the scaffold plate 1, When the hook or the like is suspended and suspended, the hook comes into contact with the peripheries of the upper surface portion 11 and the lower surface portion 12, so that the suspension posture is stable and the scaffold plate 1 can be raised and lowered safely.

また、隙間閉塞部材４は断面形状が略三角形状となっているため、隙間閉塞部材４の引っかかりなどが生じにくく、取り扱い作業性に優れている。 Further, since the gap closing member 4 has a substantially triangular cross-sectional shape, the gap closing member 4 is not easily caught and the handling workability is excellent.

隙間閉塞部材４の先端部４ａは、図４に示すように、側方から見て係止フック３の係合溝８ａの周縁部分８ｂにごく近接し、かつ周縁部分８ｂよりも遠位側に突出しないように構成されている。具体的には、図４に示すように、係止フックの先端部４ａが側面から見て係合溝８ａの周縁部分８ｂよりも遠位側に位置し、係合溝８ａと重ならないように構成されている。 As shown in FIG. 4, the front end portion 4a of the gap closing member 4 is very close to the peripheral portion 8b of the engaging groove 8a of the locking hook 3 as viewed from the side, and is more distal to the peripheral portion 8b. It is configured not to protrude. Specifically, as shown in FIG. 4, the front end portion 4a of the locking hook is located on the distal side of the peripheral portion 8b of the engaging groove 8a when viewed from the side, and does not overlap the engaging groove 8a. It is configured.

このように隙間閉塞部材４を構成することにより、図７に示すように、支柱を間に挟んで足場板１を水平材１０２に係止するいわゆるまた掛けが可能となり、仮設足場への組み立て作業の幅を広げて作業性を容易にすることができる。 By constructing the gap closing member 4 in this way, as shown in FIG. 7, so-called re-hanging is possible in which the scaffolding plate 1 is locked to the horizontal member 102 with the columns interposed therebetween, and the assembly work to the temporary scaffolding is possible. The width of the can be widened to facilitate workability.

また、上記のように、係合溝８ａの上縁、足場板本体２の上面、隙間閉塞部材４の上面部１１がいずれも同じ高さであるため、隙間閉塞部材４の先端と水平材１０２との隙間を小さくすることができ、隙間閉塞部材４を水平材１０２の上側へ被覆するように突出させなくても、工具などの落下を有効に防止することができる。 Further, as described above, since the upper edge of the engagement groove 8a, the upper surface of the scaffolding plate body 2, and the upper surface portion 11 of the gap closing member 4 are all the same height, the tip of the gap closing member 4 and the horizontal member 102 are disposed. And the gap closing member 4 can be effectively prevented from dropping without protruding so as to cover the upper side of the horizontal member 102.

なお、足場板１を水平材１０２にまた掛けした場合、支柱が係止フック３の間に存在することとなる。本実施形態にかかる足場板１は、支柱１０１に設けられるフランジ１０３は、図８に示すように、隙間閉塞部材４の下面部１２に設けられている下側貫通孔１４により隙間閉塞部材４の中空部分に入り込み、隙間閉塞部材４との干渉が回避される。 In addition, when the scaffold board 1 is hung on the horizontal member 102 again, the support column is present between the locking hooks 3. As shown in FIG. 8, the scaffold plate 1 according to the present embodiment is configured such that the flange 103 provided on the support column 101 has a lower through-hole 14 provided on the lower surface portion 12 of the gap closing member 4. It enters into the hollow portion, and interference with the gap closing member 4 is avoided.

本実施形態にかかる足場板によれば、隙間閉塞部材４が断面視三角形に構成されているため、隙間閉塞部材４に所定の厚みを持たせることが可能であり、運搬時などに他の部材に引っ掛かるなどの問題が少ない。また、断面視三角形状に構成された隙間閉塞部材４は上面部１１と下面部１２に囲まれた中空の空間が形成され、さらに下面部に下側貫通孔１４が形成されているため、支柱１０１に所定間隔ごとに設けられたフランジ１０３が当該隙間閉塞部材の下面部１２の下側貫通孔１４に入り込むことによって両者での干渉が生じない。したがって、支柱を挟んで足場板１を固定するいわゆるまた掛けとすることも可能であり、組み立て作業の幅を広げて作業性を容易にすることができる。 According to the scaffolding plate according to the present embodiment, since the gap closing member 4 is configured in a cross-sectional view triangle, the gap closing member 4 can have a predetermined thickness, and other members can be used during transportation. There are few problems such as being caught in. Further, the gap closing member 4 configured in a triangular shape in cross-section has a hollow space surrounded by the upper surface portion 11 and the lower surface portion 12, and further has a lower through hole 14 formed in the lower surface portion. The flanges 103 provided in the 101 at predetermined intervals enter the lower through hole 14 of the lower surface portion 12 of the gap closing member, so that interference between the two does not occur. Therefore, it is also possible to use a so-called hook for fixing the scaffolding plate 1 with the support interposed therebetween, and the workability can be facilitated by widening the width of the assembly work.

（第２実施形態）
図９は、本発明の第２実施形態にかかる足場板２１が仮設足場用建枠１１０にまた掛けされている状態を示す斜視図である。本実施形態にかかる足場板２１は、第１実施形態にかかる足場板１とほぼ同じ構成であるが、天板がエキスパンドメタル２６で構成されている点において異なる。 (Second Embodiment)
FIG. 9 is a perspective view showing a state in which the scaffold plate 21 according to the second embodiment of the present invention is also hung on the temporary scaffold building frame 110. The scaffold plate 21 according to the present embodiment has substantially the same configuration as the scaffold plate 1 according to the first embodiment, but differs in that the top plate is composed of the expanded metal 26.

また、本実施形態における仮設足場用建枠１１０は、支柱１１１に設けられている水平材１１２との連結に用いる取り付け部がコマ１１３ａ，１１３ｂと呼ばれる上下方向に開口を有する断面コの字状の金属部材で構成されている。 Further, the temporary scaffolding building frame 110 according to the present embodiment has a U-shaped cross section in which attachment portions used for connection with the horizontal member 112 provided on the column 111 have openings in the vertical direction called frames 113a and 113b. It is comprised with the metal member.

コマは支柱１１１の周囲に９０度ずつの位相差を持って４つが一組として設けられており、上下方向の位置が異なるようになっている。上側のコマ１１３ａと下側のコマ１１３ｂは互いに１８０度の位相差で配置される。 Four frames are provided as a set with a phase difference of 90 degrees around the column 111, and the positions in the vertical direction are different. The upper frame 113a and the lower frame 113b are arranged with a phase difference of 180 degrees from each other.

コマ１１３ａ，１１３ｂと水平材１１２は、水平材１１２の両端に設けられているくさび１１２ａをコマ１１３ａ，１１３ｂの上側から挿入することにより固定される。水平材１１２を固定するコマは、上側のコマ１１３ａでも下側のコマ１１３でもどちらでもよいが、図９では、下側のコマ１１３ｂに水平材を固定する状態を示している。 The tops 113a and 113b and the horizontal member 112 are fixed by inserting wedges 112a provided at both ends of the horizontal member 112 from above the tops 113a and 113b. The frame for fixing the horizontal material 112 may be either the upper frame 113a or the lower frame 113, but FIG. 9 shows a state in which the horizontal material is fixed to the lower frame 113b.

また、係止フック２３の係合溝の上縁、足場板本体２２の上面、隙間閉塞部材２４の上面部３１がいずれも同じ高さとなるように構成されているため、隙間閉塞部材２４の先端と水平材１１２との隙間を小さくすることができ、隙間閉塞部材２４を水平材１１２の上側へ被覆するように突出させなくても、工具などの落下を有効に防止することができる。 Further, since the upper edge of the engaging groove of the locking hook 23, the upper surface of the scaffolding plate main body 22, and the upper surface portion 31 of the gap closing member 24 are configured to have the same height, the tip of the gap closing member 24 And the horizontal member 112 can be reduced, and even if the gap closing member 24 does not protrude so as to cover the upper side of the horizontal member 112, it is possible to effectively prevent the tool or the like from dropping.

この状態の仮設足場用建枠１１０に本実施形態にかかる足場板２１をまた掛けすると、足場板２１の端面に対向する上側のコマ１１３ａが隙間閉塞部材２４に干渉する。このため、本実施形態にかかる足場板２１は、第１実施形態にかかる足場板１と同様に、上側のコマ１１３ａが隙間閉塞部材２４の下面部３２に設けられている下側貫通孔３４により隙間閉塞部材２４の中空部分に入り込み、隙間閉塞部材２４との干渉が回避される。 When the scaffold board 21 according to the present embodiment is again hung on the temporary scaffold building frame 110 in this state, the upper piece 113a facing the end surface of the scaffold board 21 interferes with the gap closing member 24. For this reason, the scaffold board 21 according to the present embodiment is similar to the scaffold board 1 according to the first embodiment by the lower through-hole 34 in which the upper piece 113a is provided in the lower surface portion 32 of the gap closing member 24. It enters into the hollow portion of the gap closing member 24 and interference with the gap closing member 24 is avoided.

また、上側貫通孔３３，下側貫通孔３４は、例えば、足場板２１を吊り下げて高所に持ち上げる際に使用されるクレーンなどの吊り下げ部材を係止する場合に好適に使用することができる。 Further, the upper through-hole 33 and the lower through-hole 34 can be preferably used when, for example, a suspension member such as a crane used to suspend the scaffold plate 21 and lift it to a high place is locked. it can.

このように、本発明の各実施形態によれば、隙間閉塞部材が所定の厚みを持って構成されているため、運搬時などに他の部材に引っ掛かるなどの問題が少ない。また、隙間閉塞部材４の上面部１１と下面部１２に囲まれた領域は中空であり、さらに下面部に下側貫通孔１４が形成されているため、支柱１０１に所定間隔ごとに設けられた支柱の取り付け部を収容することができ、支柱との干渉が生じない。 Thus, according to each embodiment of the present invention, since the gap closing member is configured with a predetermined thickness, there are few problems such as being caught by other members during transportation. Moreover, since the area | region enclosed by the upper surface part 11 and the lower surface part 12 of the gap | blocking obstruction | occlusion member 4 is hollow, and also the lower side through-hole 14 is formed in the lower surface part, it provided in the support | pillar 101 for every predetermined space | interval. The attachment part of a support | pillar can be accommodated and interference with a support | pillar does not arise.

なお、本発明は上記実施形態に限定されるものではなく、その他種々の態様で実施可能である。例えば、上記実施形態では、係合溝８ａの上縁、足場板本体２の上面、隙間閉塞部材４の上面部１１がいずれも同じ高さとすることで先端と水平材１０２との隙間を小さくすることとしているが、例えば、少なくとも係合溝８ａ手前側の縁と隙間閉塞部材４の先端がごく近接していれば、上面部１１と水平材の上端及び足場板本体２の上面との間に段差が設けられていても水平材１０２との隙間を小さくすることが可能である。すなわち、隙間閉塞部材４の上面部１１と水平材１０２及び足場板本体２の上面とに多少の段差が設けられていてもよい。 In addition, this invention is not limited to the said embodiment, It can implement in another various aspect. For example, in the above embodiment, the upper edge of the engagement groove 8a, the upper surface of the scaffolding plate body 2, and the upper surface portion 11 of the gap closing member 4 are all the same height, thereby reducing the gap between the tip and the horizontal member 102. However, for example, if at least the edge on the front side of the engagement groove 8a and the tip of the gap closing member 4 are very close to each other, it is between the upper surface portion 11 and the upper end of the horizontal member and the upper surface of the scaffold plate body 2. Even if a step is provided, the gap with the horizontal member 102 can be reduced. That is, a slight level difference may be provided between the upper surface portion 11 of the gap closing member 4 and the upper surfaces of the horizontal member 102 and the scaffold board body 2.
