Description

本発明は、仮設足場の幅木材に関し、特に必要により足場板との隙間を埋めることができる幅木材に関する。   The present invention relates to a width timber for a temporary scaffold, and more particularly to a width timber capable of filling a gap with a scaffold plate if necessary.

建築現場等に構築される仮設足場は、支柱と横柱（横架材、腕木、横桟等とも称される）との組み合わせからなる枠組みに足場板が設置されて組み立てられる。足場板は主に横架材上に組み付けられ、仮設足場は出来上がる。このような仮設足場は高所作業を伴うことから、足場の安全性に十分な配慮が必要となる。例えば、作業者による足場板の踏み外し、工具類の落下等を防ぐ必要がある。   Temporary scaffolding constructed at a construction site or the like is assembled by installing a scaffolding board in a framework composed of a combination of columns and horizontal pillars (also called horizontal members, arms, horizontal rails, etc.). The scaffolding board is mainly assembled on the horizontal member, and the temporary scaffolding is completed. Since such a temporary scaffold involves work at a high place, sufficient consideration must be given to the safety of the scaffold. For example, it is necessary to prevent the operator from stepping off the scaffolding board and dropping the tools.

そこで、仮設足場における足場板付近の安全性を高めるべく、幅木材等が足場板の片側もしくは両側に設置される。このような幅木材は足場板の長さに等しい長尺の板材からなり、その両端にフック形状等の係合部が備えられ、枠組みの支柱や横柱等と固定される（例えば、特許文献１，特許文献２，特許文献３等参照）。幅木材は現場での取り付けが容易なため、現在では広く普及している。   Therefore, in order to increase the safety in the vicinity of the scaffolding plate in the temporary scaffolding, width wood or the like is installed on one side or both sides of the scaffolding plate. Such a width timber is made of a long plate material equal to the length of the scaffold plate, and is provided with engagement portions such as hook shapes at both ends thereof, and is fixed to a frame column or a horizontal column (for example, Patent Documents) 1, patent document 2, patent document 3, etc.). Width timber is now widely used because it can be easily installed on site.

足場板の横幅は大抵統一されているものの、資材調達等の都合上、現場においては異なる横幅の足場板が混在して設置される場合がある。そのため、足場板の横幅いかんにより、足場板の横に設置される幅木材と、足場板との隙間が広がってしまうことがある。   Although the width of the scaffolding board is usually uniform, there are cases where scaffolding boards of different widths are installed together on site because of material procurement. Therefore, depending on the width of the scaffold board, a gap between the width timber installed beside the scaffold board and the scaffold board may be widened.

しかしながら、各特許文献に開示されている幅木材にあっては、幅木材自体に幅木材と足場板との間に生じた隙間を解消する機能を備えたものは無く、幅木材と足場板との隙間の解消を図り安全性をより向上させた構成は未だに存在しなかった。そこで、仮設足場の足場板付近の安全性確保、特に足場板との隙間の解決が課題となっていた。   However, in the width timber disclosed in each patent document, none of the width timber itself has a function of eliminating a gap generated between the width timber and the scaffold plate, However, there has not yet been a configuration that improves the safety by eliminating the gaps. Therefore, securing safety in the vicinity of the scaffolding plate of the temporary scaffold, in particular, solving the gap with the scaffolding plate has been an issue.

請求項１の発明に規定するように、幅木材１０は、一定の本体高さ幅Ｈの幅木板本体１１を有する。幅木板本体１１の内側１２に該幅木板本体１１の高さよりも低い幅Ｍの補助板材２０が内装されている。図１の破線で示した補助板材２０のように、足場板６０に対して倒置可能となっている。幅木板本体１１の長手方向全体を通じて、その下部１３に断面「コ」字状の溝部（下部側溝部１４）が形成される。図示の例では、幅木板本体１１の上部１５にも断面コ字状の溝部（上部側溝部１６）が形成される。   As defined in the invention of claim 1, the width wood 10 has a baseboard board body 11 having a constant body height width H. An auxiliary plate member 20 having a width M lower than the height of the skirting board main body 11 is provided inside the skirting board main body 11. Like the auxiliary plate 20 shown by the broken line in FIG. Through the entire longitudinal direction of the skirting board main body 11, a groove portion (lower groove portion 14) having a “U” cross section is formed in the lower portion 13. In the illustrated example, a groove portion (upper side groove portion 16) having a U-shaped cross section is also formed in the upper portion 15 of the skirting board main body 11.

幅木材１０にあっては、請求項３の発明に規定するように、幅木板本体１１の両側１７には、仮設足場１の横柱３へ取り付けるためのフック部１８が連結板部材３０に接続されて設けられている。図示の実施例では、左端側１７ａに装着された左側連結板部材３１を介して左側フック部１８ａが設けられ、同様に右端側１７ｂに装着された右側連結板部材３２を介して右側フック部１８ｂが設けられている。フック部により、仮設足場１の横柱３への取り付けは容易となる。図２から把握されるように、幅木板本体、左右の連結板部材、及びフック部の固定にはボルト４１、ナット４２が用いられる。この他に、リベットによる固定、溶接等も用いられる。なお、前記の横柱３は横架材、腕木、横桟等とも称される。   In the width timber 10, as defined in the invention of claim 3, hooks 18 for attaching to the horizontal pillar 3 of the temporary scaffold 1 are connected to the connecting plate member 30 on both sides 17 of the skirting board main body 11. Has been provided. In the illustrated embodiment, a left hook portion 18a is provided via a left connecting plate member 31 mounted on the left end side 17a, and a right hook portion 18b is similarly connected via a right connecting plate member 32 mounted on the right end side 17b. Is provided. The hook portion makes it easy to attach the temporary scaffold 1 to the horizontal column 3. As can be understood from FIG. 2, bolts 41 and nuts 42 are used to fix the skirting board main body, the left and right connecting plate members, and the hook portion. In addition, fixing with rivets, welding, and the like are also used. The horizontal pillar 3 is also referred to as a horizontal member, a brace, a horizontal rail, or the like.

連結板部材３０の上側には、断面「く」の字状に屈曲した重合板部材３５が備えられる。図示の左側連結板部材３１の上側には、断面「く」の字状に屈曲した左側重合板部材３３が形成され、右側連結板部材３２の上側にも、相補的に重なり合うように右側重合板部材３４が形成される。また、左側連結板部材３１及び右側連結板部材３２のそれぞれには、穴部３８を有するクリップ受け部３９が備えられる。左側連結板部材３１、右側連結板部材３２等の作用は後述する。   On the upper side of the connecting plate member 30, there is provided a superposed plate member 35 bent in a cross-section “<” shape. On the upper side of the left connecting plate member 31 shown in the figure, a left overlapping plate member 33 bent in a cross-section “<” shape is formed, and on the upper side of the right connecting plate member 32, the right overlapping plate member so as to complementarily overlap. A member 34 is formed. Each of the left connecting plate member 31 and the right connecting plate member 32 is provided with a clip receiving portion 39 having a hole 38. The operation of the left connecting plate member 31, the right connecting plate member 32, etc. will be described later.

図３、図４を用い足場板６０に対する補助板材２０の倒置の状態を説明する。図示では幅木材１０の左端側１７ａにおいて左側連結板部材３１等を取り外し幅木板本体１１内部の構造を開示する。請求項２の発明に規定するように、幅木板本体１１の下部１３に断面コ字状の溝部（下部側溝部１４）が設けられる。補助板材２０の下部２３には下部側溝部１４に収容される突状部２４が形成される。突状部２４も断面コ字状の溝部である。図の符号Ｈは幅木板本体の本体高さ幅であり、Ｍは補助板材の幅である。   A state in which the auxiliary plate member 20 is inverted with respect to the scaffold plate 60 will be described with reference to FIGS. 3 and 4. In the drawing, the left connecting plate member 31 and the like are removed from the left end side 17a of the width wood 10 to disclose the structure inside the width board main body 11. As defined in the invention of claim 2, a groove portion (lower groove portion 14) having a U-shaped cross section is provided in the lower portion 13 of the baseboard body 11. A projecting portion 24 accommodated in the lower groove portion 14 is formed in the lower portion 23 of the auxiliary plate member 20. The protrusion 24 is also a groove having a U-shaped cross section. The symbol H in the figure is the body height width of the baseboard body, and M is the width of the auxiliary plate material.

実施例の補助板材２０では、１枚の長尺の鋼板を折り曲げることにより、曲げ板部２２と前記の突状部２４が形成される。補助板材２０の突状部２４は下部側溝部１４に収容されることから、下部側溝部１４は突状部２４の幅よりも十分に大きく形成される。そのため、図３、図４のとおり、補助板材２０を倒置する際の回動が円滑となる。符号２１は補助板材の板部、６１は足場板の上板部である。   In the auxiliary plate material 20 of the embodiment, the bent plate portion 22 and the protruding portion 24 are formed by bending a single long steel plate. Since the protruding portion 24 of the auxiliary plate member 20 is accommodated in the lower groove portion 14, the lower groove portion 14 is formed sufficiently larger than the width of the protruding portion 24. Therefore, as shown in FIGS. 3 and 4, the rotation when the auxiliary plate member 20 is inverted is smooth. Reference numeral 21 denotes a plate portion of the auxiliary plate material, and 61 denotes an upper plate portion of the scaffold plate.

図３に示しているように、足場板６０の横幅いかんにより、幅木材（幅木板本体１１）と足場板６０とは、隙間Ｓａの長さ分だけ離れてしまう場合がある。そこで図４のとおり、幅木材（幅木板本体）と足場板との隙間Ｓａを埋め合わせるため、幅木板本体１１内に格納されている補助板材２０は、突状部２４を回動の中心にして足場板６０に向けて倒される。この結果、補助板材の板部２１、曲げ板部２２が、足場板６０の上板部６１、縁部６２に到達する。そこで、幅木材自体によって、幅木材（幅木板本体）と足場板との隙間Ｓａは塞がれる。自明ながら、幅木材と足場板との隙間を塞ぐための他の資材を必要としない。よって、作業現場における資材数の抑制が可能となる。むろん、幅木材（幅木板本体）と足場板との間隔によっては、補助板材２０が倒されない場合もある。   As shown in FIG. 3, due to the lateral width of the scaffold board 60, the width wood (baseboard board body 11) and the scaffold board 60 may be separated by the length of the gap Sa. Therefore, as shown in FIG. 4, in order to make up the gap Sa between the skirting timber (baseboard main body) and the scaffolding board, the auxiliary plate 20 stored in the skirting board main body 11 has the protruding portion 24 as the center of rotation. Defeated toward the scaffolding plate 60. As a result, the plate portion 21 and the bent plate portion 22 of the auxiliary plate material reach the upper plate portion 61 and the edge portion 62 of the scaffold plate 60. Therefore, the gap Sa between the width timber (baseboard board main body) and the scaffold board is closed by the width timber itself. Obviously, no other materials are needed to close the gap between the width timber and the scaffolding board. Therefore, the number of materials at the work site can be reduced. Of course, depending on the distance between the width wood (baseboard main body) and the scaffold board, the auxiliary board 20 may not be brought down.

補助板材２０の倒置時においても、突状部２４と下部側溝部１４とが係合しているため、安易に補助板材２０が幅木板本体１１から外れないようになっている。実施例にあっては、下部側溝部１４の端部に溝縁部１４ｆが設けられ、断面コ字状の突状部２４が溝縁部１４ｆに引っかかるため、幅木板本体と足場板との係合状態は維持される。図示しないが、補助板材と幅木板本体との係合に際し、補助板材の端部と幅木板本体の下部とを公知の蝶番により接続して補助板材を回動させることができる。また、幅木板本体の下部に適宜の回動軸を配置し、これに補助板材の端部を接続して双方の回動を容易としてもよい。   Even when the auxiliary plate member 20 is turned over, the protruding portion 24 and the lower groove portion 14 are engaged with each other, so that the auxiliary plate member 20 is not easily detached from the skirting board main body 11. In the embodiment, the groove edge portion 14f is provided at the end of the lower groove portion 14, and the projecting portion 24 having a U-shaped cross section is caught by the groove edge portion 14f. The combined state is maintained. Although not shown, when the auxiliary plate member and the skirting board main body are engaged, the end of the auxiliary plate member and the lower part of the skirting board main body can be connected by a known hinge to rotate the auxiliary plate member. In addition, an appropriate rotation shaft may be disposed at the lower part of the skirting board main body, and an end portion of the auxiliary plate material may be connected thereto to facilitate both rotations.

これより幅木材１０と仮設足場１との固定の様子を説明する。図５の斜視図に示した実施例の足場板６０では、仮設足場１の横柱３に足場板フック部６８を介して設置される。続いて幅木材１０を仮設足場１に固定するに際し、幅木板本体１１の両側１７（左端側１７ａ，右端側１７ｂ）にそれぞれ設けられているフック部１８（左側フック部１８ａ，右側フック部１８ｂ）を介して横柱３に設置される。   The state of fixing the width wood 10 and the temporary scaffold 1 will now be described. In the scaffold board 60 of the embodiment shown in the perspective view of FIG. 5, the scaffold board 60 is installed on the horizontal pillar 3 of the temporary scaffold 1 via the scaffold board hook portion 68. Subsequently, when the width wood 10 is fixed to the temporary scaffold 1, hook portions 18 (left hook portion 18 a and right hook portion 18 b) provided on both sides 17 (the left end side 17 a and the right end side 17 b) of the baseboard body 11, respectively. It is installed in the horizontal pillar 3 via.

図示から把握できるように、紙面右側の幅木材１０のフック部１８（左側フック部１８ａ）に、紙面左側の幅木材１０のフック部１８（右側フック部１８ｂ）が重ね合わされる。同時に、左側フック部１８ａを備える左側連結板部材３１に、右側フック部１８ｂを備える右側連結板部材３２が重ね合わされる。すなわち、幅木材１０，１０の端部同士の接合部位において、互いに差し込まれるようにして連結される。   As can be seen from the drawing, the hook portion 18 (right hook portion 18b) of the width wood 10 on the left side of the paper is superimposed on the hook portion 18 (left hook portion 18a) of the width wood 10 on the right side of the paper. At the same time, the right connecting plate member 32 including the right hook portion 18b is superimposed on the left connecting plate member 31 including the left hook portion 18a. That is, in the joining site | part of the edge parts of the width | variety timbers 10 and 10, it connects so that it may be inserted mutually.

互いの幅木材が仮設足場の所定位置に設置された後、支柱２の背後に該支柱と当接する幅木用クリップ部材５０が介装される。幅木用クリップ部材５０は２本の脚部５１，５１を有して折り曲げられたＵ字状（Ｖ字状）の部材である。幅木用クリップ部材５０の脚部５１，５１は、左側連結板部材３１のクリップ受け部３９及び右側連結板部材３２のクリップ受け部３９の穴部３８にそれぞれ挿入される。こうして、幅木材１０，１０は仮設足場１の横柱３上に互いに連結し合って配置され、幅木用クリップ部材５０を介して支柱２とも固定される。ゆえに、幅木材１０，１０の仮設足場１への固定は強固となる。   After the mutual width timbers are installed at predetermined positions on the temporary scaffolding, a base plate clip member 50 that comes into contact with the support column is interposed behind the support column 2. The base plate clip member 50 is a U-shaped (V-shaped) member that has two leg portions 51 and 51 and is bent. The leg portions 51 of the skirting board clip member 50 are inserted into the hole portions 38 of the clip receiving portion 39 of the left connecting plate member 31 and the clip receiving portion 39 of the right connecting plate member 32, respectively. In this way, the width timbers 10 are arranged so as to be connected to each other on the horizontal column 3 of the temporary scaffold 1, and are also fixed to the column 2 via the skirting clip member 50. Therefore, the fixing of the width timbers 10 and 10 to the temporary scaffold 1 becomes strong.

次に図６、図７を用い幅木材同士の連結状況を説明する。図６は幅木材１０を幅木板本体１１の左端側１７ａから見た際の左側面図であり、まず、一の幅木材１０を仮設足場１の横柱３に係合した状況である。幅木材１０において、紙面左側から、幅木板本体１１の本体高さ幅を構成する側板部１９、左側連結板部材３１、左側フック部１８ａの順に適度な間隔を置いて並設される。間隔はボルト４１や図示しないワッシャ等により調整される。なお、図示では便宜上、前記のクリップ受け部を省略した。   Next, the connection state of width timbers is demonstrated using FIG. 6, FIG. FIG. 6 is a left side view of the width timber 10 as viewed from the left end side 17 a of the skirting board main body 11. First, one width timber 10 is engaged with the horizontal pillar 3 of the temporary scaffold 1. In the width timber 10, the side plate 19, the left connecting plate member 31, and the left hook portion 18 a constituting the main body height width of the skirting board main body 11 are arranged in order from the left side of the drawing with an appropriate interval. The interval is adjusted by a bolt 41 or a washer (not shown). In the drawing, the clip receiving portion is omitted for convenience.

図７は、図６の幅木材１０にさらに他の幅木材を仮設足場１の横柱３に係合した状態である。一の幅木材１０の左側フック部１８ａの右横に他の幅木材の右側フック部１８ｂが並置される（図５参照）。そして、他の幅木材の右側連結板部材３２が、一の幅木材の左側連結板部材３１と左側フック部１８ａとの間に形成された隙間Ｓｊの中に挿入される。左側連結板部材３１に右側連結板部材３２が重ね合わされる（図５の別視点のとおりである。）。また、両連結板部材の上部においても、一の幅木材の左側重合板部材３３に他の幅木材の右側重合板部材３４が重ね合わされる。   FIG. 7 shows a state in which another width wood is engaged with the horizontal pillar 3 of the temporary scaffold 1 in addition to the width wood 10 of FIG. On the right side of the left hook portion 18a of one width wood 10, the right hook portion 18b of another width wood is juxtaposed (see FIG. 5). Then, the right connecting plate member 32 of another width wood is inserted into a gap Sj formed between the left connecting plate member 31 of the one width wood and the left hook portion 18a. The right connecting plate member 32 is overlaid on the left connecting plate member 31 (as in another viewpoint in FIG. 5). In addition, also on the upper part of both the connecting plate members, the right overlapping plate member 34 of the other width wood is superimposed on the left overlapping plate member 33 of one width wood.

左側重合板部材３３には断面く字状に屈曲形成され正面辺部３３ｐが形成される。また、右側重合板部材３４には前記の左側重合板部材３３の正面辺部３３ｐと重なり合う断面く字状に屈曲形成された背面辺部３４ｑが形成される。このため、左側重合板部材３３と右側重合板部材３４との表裏の重なりにより、右側連結板部材３２を左側連結板部材３１に組み合わせる際の位置決めは容易となる。   The left overlapping plate member 33 is bent to have a square cross section, and a front side portion 33p is formed. The right overlapping plate member 34 is formed with a back side portion 34q that is bent and formed in a cross-sectional shape that overlaps the front side portion 33p of the left overlapping plate member 33. For this reason, positioning when combining the right connecting plate member 32 with the left connecting plate member 31 is facilitated by the overlap of the left and right overlapping plate members 33 and the right overlapping plate member 34.

加えて、左右の重合板部材の辺部同士は断面く字状であることから、いったん左右の重合板部材同士で組み合わさった後は容易に上下に移動し難くなり、左側連結板部材に重なられる右側連結板部材の上下方向の位置ずれを抑制できる。図示から把握されるように、他の幅木材において、右側連結板部材３２及び右側フック部１８ｂは、連結対象となる一の幅木材１０の側板部１９、左側連結板部材３１、左側フック部１８ａと異なる間隔に調整されてなる。なお、幅木材は仮設足場に連続して配置される。そこで、一の幅木材の幅木板本体１１の左端側１７ａと右端側１７ｂにおいて、側板部、連結板部材、フック部は、左右で重なり合って組み合わされる量だけ互いにずらした間隔に形成される。   In addition, since the sides of the left and right overlapping plate members have a cross-sectional shape, once they are combined with the left and right overlapping plate members, it becomes difficult to move up and down easily. The positional deviation of the right connecting plate member in the vertical direction can be suppressed. As can be seen from the figure, in other width wood, the right connection plate member 32 and the right hook portion 18b are the side plate portion 19, left connection plate member 31, left hook portion 18a of one width wood 10 to be connected. And adjusted to a different interval. The width timber is continuously arranged on the temporary scaffold. Therefore, on the left end side 17a and the right end side 17b of the skirting board main body 11 of one width timber, the side plate portion, the connecting plate member, and the hook portion are formed at intervals that are shifted from each other by an amount that is overlapped and combined.

図８の斜視図は他の実施例に係る仮設足場の幅木材１０Ａの主要部を開示する。幅木材１０Ａでは、左側連結板部材３１に保持片部材４５が備えられる。実施例の保持片部材４５は、ボルト４１、ナット４２間に回動可能に介装される。幅木板本体１１の内側１２に内装された補助板材２０が不使用時に幅木板本体から倒れなくするため、保持片部材４５（実線表記）は、補助板材と当接しその倒置を防いでいる。なお、補助板材２０の使用時、保持片部材４５は矢印の向きに回動され（破線表記）、保持片部材と補助板材との当接は解除される。このため、補助板材の不用意な倒置のおそれは解消される。保持片部材４５は、左側連結板部材３１または右側連結板部材３２のいずれかもしくは両方に備えられる。   The perspective view of FIG. 8 discloses the main part of the width timber 10A of the temporary scaffold according to another embodiment. In the width timber 10 </ b> A, the left connecting plate member 31 includes a holding piece member 45. The holding piece member 45 of the embodiment is interposed between the bolt 41 and the nut 42 so as to be rotatable. In order to prevent the auxiliary plate member 20 built in the inner side 12 of the skirting board main body 11 from falling from the skirting board main body when not in use, the holding piece member 45 (indicated by a solid line) is in contact with the auxiliary plate member and prevents its inversion. When the auxiliary plate member 20 is used, the holding piece member 45 is rotated in the direction of the arrow (shown by a broken line), and the contact between the holding piece member and the auxiliary plate member is released. For this reason, the fear of inadvertent inversion of the auxiliary plate material is eliminated. The holding piece member 45 is provided on either or both of the left connecting plate member 31 and the right connecting plate member 32.

図９及び図１０の斜視図はさらに他の実施例に係る仮設足場の幅木材１０Ｂの主要部を開示する。幅木材１０Ｂでは、幅木板本体１１の下部１３に断面コ字状の溝部（下部側溝部１４Ｂ）が設けられており、下部側溝部１４Ｂは前掲の実施例の下部側溝部１４よりも深く形成されている。つまり、深溝下部側溝部となる。溝部自体を深くすることにより、不使用時の補助板材２０（その下部２３の突状部２４）は、下部側溝部１４Ｂの深さＤｐに応じて、より深く幅木板本体１１の下部側溝部１４Ｂの内部に収容される（図１０参照）。   The perspective view of FIG.9 and FIG.10 discloses the principal part of the width | variety wood 10B of the temporary scaffold which concerns on another Example. In the width timber 10B, a groove portion (lower side groove portion 14B) having a U-shaped cross section is provided in the lower portion 13 of the skirting board main body 11, and the lower side groove portion 14B is formed deeper than the lower side groove portion 14 of the foregoing embodiment. ing. That is, it becomes a deep groove lower side groove part. By making the groove itself deeper, the auxiliary plate 20 when not in use (the protruding portion 24 of the lower portion 23) is deeper in accordance with the depth Dp of the lower groove portion 14B, and the lower groove portion 14B of the baseboard body 11 is deeper. (See FIG. 10).

図示のとおり、深溝の下部側溝部１４Ｂとしたことにより、幅木板本体１１の内側１２に内装されている不使用時の補助板材２０の重心位置も低くなる。そこで、補助板材２０が倒置しようとしても、先に補助板材の板部２１が溝壁部１４ｗ、図示では溝縁部１４ｆに当接して補助板材の倒置は抑制される。補助板材の収容しているときの補助板材のがたつきを防ぐために、下部側溝部１４Ｂの深さＤｐ、溝縁部１４ｆの長さは最適に設定される。こうして、補助板材の不用意な倒置のおそれは解消される。   As shown in the figure, by setting the lower groove portion 14B of the deep groove, the position of the center of gravity of the auxiliary plate 20 when not in use, which is housed in the inner side 12 of the skirting board main body 11, is lowered. Therefore, even if the auxiliary plate member 20 is to be turned over, the plate portion 21 of the auxiliary plate member is first brought into contact with the groove wall portion 14w, in the drawing, the groove edge portion 14f, thereby suppressing the turnover of the auxiliary plate member. In order to prevent rattling of the auxiliary plate material when the auxiliary plate material is housed, the depth Dp of the lower groove portion 14B and the length of the groove edge portion 14f are set optimally. In this way, the risk of inadvertent inversion of the auxiliary plate material is eliminated.

補助板材２０を使用する場合、いったん補助板材は垂直方向に持ち上げられる。補助板材の突状部２４が溝縁部１４ｆと接触したところで幅木板本体１１の内側１２からその外へ向けて倒される。収容時はこの逆である。   When the auxiliary plate member 20 is used, the auxiliary plate member is once lifted in the vertical direction. When the projecting portion 24 of the auxiliary plate material comes into contact with the groove edge portion 14f, the auxiliary plate material is tilted outward from the inner side 12 of the skirting board main body 11. The opposite is true during containment.

各実施例に開示の幅木材１０，１０Ａ，１０Ｂにあっては、単独で構成しても、それぞれを組み合わせても良い。また、幅木板本体の本体高さ幅Ｈ、補助板材の幅Ｍ等は施工対象となる仮設足場に応じて適宜の寸法となる。各図において、共通する箇所は同一符号とした。   In the width timber 10, 10A, 10B disclosed in each embodiment, it may be constituted alone or in combination. Further, the body height width H of the skirting board main body, the width M of the auxiliary board material, and the like have appropriate dimensions according to the temporary scaffolding to be constructed. In each figure, common portions are denoted by the same reference numerals.
