Description

【０００１】
【発明の属する技術分野】
本発明は、建設作業現場で枠組みされる仮設枠組足場において、対向する足場用建枠の横材間に架け渡された足場板の側端部間の隙間を塞ぐ足場板隙間カバーに関するものである。
【０００２】
【従来の技術】
図１２は建設作業現場で枠組みされた仮設枠組足場の一部を示したもので、各足場用建枠１は、一対の縦材３，３と、両縦材３，３をつなぐ横材２，２と、補強材４，４とによって形成され、上下複数段に継ぎ足される。足場板５は、金属板製の足場板本体６とこれの両端部に突設された係止フック７，７と、からなるもので、一定間隔おきに立設された対向する足場用建枠１，１の横材２，２間に足場板５が横方向に２枚ずつ並列状態に架け渡されて、作業通路を形成する。
【０００３】
【発明が解決しようとする課題】
上記のように足場板５が足場用建枠１，１の横材２，２間に横方向に並列状態に架け渡されると、横材２に対向方向から係止される係止フック７，７の配置関係上、どうしても横方向に隣合う両足場板５，５の側端部間に隙間Ｓができる。このような隙間Ｓが作業通路に存在すると、ボルト・ナット等の金具や工具を誤って隙間Ｓから落としてしまった時、その金具や工具が下方の同様な作業通路で作業中の作業者に当たって怪我をさせるおそれがあり、また作業通路に隙間Ｓがあると、作業者が隙間Ｓに足を引っ掛け、転んでしまうおそれがあるなど、非常に危険である。
【０００４】
また、普通の足場板５は、幅が５００ｍｍ、長さが概ね１６００ｍｍの足場板本体６からなるもので、この足場板本体６は、図１２に概略示すように、２５０ｍｍの幅を有する２枚の半割板体６ａ，６ａの側端面どうしを接合して形成されているが、古くから使用されている足場板には、２枚の半割板体を横方向に２０ｍｍ程度間隔を開けて両者を一体に連結することにより形成されたものがある。このような足場板にあっては、各足場板自体に既に前記の隙間Ｓと同様な隙間が形成されているから、上記同様な問題が生ずることになる。尚、図１２に示した例では、横方向に隣合う両足場板５，５の側端部間に隙間Ｓは２５ｍｍ程度である。
【０００５】
本発明の上記のような問題点に鑑み、足場用建枠の横材間に架け渡される足場板の側端部間に形成された隙間を簡単な作業で確実に塞ぐことのできる足場板隙間カバーを提供することを目的とする。ここで、足場板の側端部間に形成された隙間とは、足場用建枠の横材間に複数枚の足場板を横方向に並列状態に架け渡した場合に形成される隙間の他に、足場用建枠の横材間に足場板を架け渡した時にその足場板を形成する２枚の半割板体の側端部間に形成されている隙間も含むものとする。

【発明の実施の形態】
以下に、本発明の実施形態について説明すると、図１は、対向する足場用建枠１，１の横材２，２間に２枚の足場板５，５が並列に架け渡された状態を示す。この図において、Ｓ₁は横方向に隣合う両足場板５，５の足場板本体６，６の側端部間に形成された隙間であり、Ｓ₂は各足場板５の足場板本体６を形成する２枚の半割足場板本体６ａ，６ａの側端部間に形成された隙間である。しかして、隙間Ｓ₁及び隙間Ｓ₂には夫々隙間カバー１０が装着されるようになっている。図２は、隙間カバー１０を隙間Ｓ₁及び隙間Ｓ₂に装着しようとしている状態を示したものである。
【００１０】
足場板５の寸法を参考までに、その一例を示せば、足場板本体６の長さは１６５６ｍｍ、その幅は５００ｍｍであり、この足場板本体６を形成する各半割足場板本体６ａの幅は２４０ｍｍである。そして、図１に示すように、両足場板５，５の足場板本体６，６の側端部間に形成される隙間Ｓ₁の幅は２５ｍｍであり、足場板本体６を形成する２枚の半割足場板本体６ａ，６ａの側端部間に形成された隙間Ｓ₂は２０ｍｍである。
【００１１】
図３は隙間カバー１０を示す斜視図である。また、図５は隙間カバー１０の横断面図、図６は各足場板５の足場板本体６を形成する２枚の半割足場板本体６ａ，６ａの側端部間に形成された隙間Ｓ₂に隙間カバー１０を装着した状態を示す横断面図、図７は両足場板５，５の足場板本体６，６の側端部間に形成された隙間Ｓ₁に隙間カバー１０を装着した状態を示す横断面図である。
【００１２】
隙間カバー１０の構造について説明すると、この隙間カバー１０は、図３及び図５に示すように、カバー本体１１と、このカバー本体１１を保持するための両側一対の保持脚部１２，１２とからなるもので、一対の保持脚部１２，１２は、ポリ塩化ビニルやポリエチレン等の合成樹脂の押出成形によってカバー本体１１の下面長手方向全域に沿って一体に形成される。
【００１３】
カバー本体１１は、概ね平板状に形成されたもので、その幅方向両端部１１ａ，１１ａが、図７に示すように横方向（足場板５の長手方向と直交する方向）に隣合う両足場板５，５の足場板本体６，６に跨がって支持されるか、又は図６に示すように各足場板５を形成する両半割足場板本体６ａ，６ａに跨がって支持されるようになっている。尚、カバー本体１１の上面には滑り止め用の浅い溝部１３がカバー本体長手方向に条設されている。
【００１４】
両側一対の保持脚部１２，１２は、カバー本体幅方向両端部１１ａ，１１ａ下面の夫々内方端部から下向きに平行に垂設されたもので、両保持脚部１２，１２の下端部には、図７に示すように隙間Ｓ₁に臨んで対向する両足場板本体６，６の側端面８，８に係止するか、又は図６に示すように隙間Ｓ₂に臨んで対向する両半割足場板本体６ａ，６ａの側端面９，９に係止する断面円弧状の外向き突条部１２ａ，１２ａが形成されている。両外向き突条部１２ａ，１２ａは、両保持脚部１２，１２が隙間Ｓ₁又は隙間Ｓ₂に突入した時、両足場板本体６，６の対向側端面８，８又は両半割足場板本体６ａ，６ａの対向側端面９，９に対し弾性係止するように、外端面間の距離Ｈ（図５参照）が隙間Ｓ₁の幅Ｗ₁（図７参照）又は隙間Ｓ₂の幅Ｗ₂（図６参照）よりも若干広くなるように形成される。
【００１５】
従って、この隙間カバー１０を隙間Ｓ₁又は隙間Ｓ₂に装着するにあたって、両保持脚部１２，１２を隙間Ｓ₁又は隙間Ｓ₂に突入させる時は、外向き突条部１２ａ，１２ａが断面円弧状に丸く形成されていて、突条部１２ａ，１２ａの下端部が突入ガイドとなるため、両保持脚部１２，１２を隙間Ｓ₁又は隙間Ｓ₂の真上からそのまま降ろして押し込むようにすれば、両保持脚部１２，１２の下端部側が互いに閉じる方向弾性変形して、両保持脚部１２，１２を隙間Ｓ₁又は隙間Ｓ₂に容易に突入させることができ、また隙間Ｓ₁又は隙間Ｓ₂に突入した両保持脚部１２，１２の突条部１２ａ，１２ａが両足場板本体６，６の対向側端面８，８又は両半割足場板本体６ａ，６ａの対向側端面９，９に対し弾性係止することによって、カバー本体１１を両足場板本体６，６間又は両半割足場板本体６ａ，６ａ間に架け渡した状態に確実に保持することができる。
【００１６】
図４は上記隙間カバー１０とは若干形状の異なった他の実施形態による隙間カバー２０を示す斜視図である。図８は図４に示す隙間カバー２０の横断面図、図９は各足場板５の足場板本体６を形成する２枚の半割足場板本体６ａ，６ａの側端部間に形成された隙間Ｓ₂に隙間カバー２０を装着した状態を示す横断面図、図１０は両足場板５，５の足場板本体６，６の側端部間に形成された隙間Ｓ₁に隙間カバー２０を装着した状態を示す横断面図である。
【００１７】
この隙間カバー２０は、前記隙間カバー１０とほとんど同様な構成であるが、両保持脚部２２，２２が、夫々の下端部から外向きに突出して、図１０に示すように両足場板本体６，６の側端面８，８の夫々下端縁部８ｏ，８ｏに係止するか、又は図９に示すように両半割足場板本体６ａ，６ａの側端面９，９の夫々下端縁部９ｏ，９ｏに係止する鉤形の係止部片２２ａ，２２ａを備えていて、両鉤形係止部片２２ａ，２２ａの下端面が図示のようにテーパに形成されているところが異なっている。
【００１８】
従って、隙間カバー２０を隙間Ｓ₁又は隙間Ｓ₂に装着するにあたって、両保持脚部１２，１２をその隙間Ｓ₁又は隙間Ｓ₂に突入させる時は、両鉤形係止部片２２ａ，２２ａのテーパ状下端面が突入ガイドとなるため、両保持脚部２２，２２を隙間Ｓ₁又は隙間Ｓ₂の真上からそのまま降ろして押し込むようにすれば、隙間カバー１０の場合と同様に、両保持脚部２２，２２の下端部側が互いに閉じる方向に弾性変形して、両保持脚部２２，２２を隙間Ｓ₁又は隙間Ｓ₂に容易に突入させることができる。
【００１９】
しかして、隙間Ｓ₁又は隙間Ｓ₂に突入した両保持脚部２２，２２の鉤形係止部片２２ａ，２２ａが図１０に示すように両足場板本体６，６の側端面８，８の夫々下端縁部８ｏ，８ｏに係止するか、又は図９に示すように両半割足場板本体６ａ，６ａの側端面９，９の夫々下端縁部９ｏ，９ｏに係止することによって、両保持脚部２２，２２が図８のような平行な状態に弾性復帰して、カバー本体２１を両足場板本体６，６間又は両半割足場板本体６ａ，６ａ間に架け渡した状態に確実に保持することができる。
【００２０】
この隙間カバー２０は、両保持脚部２２，２２の鉤形係止部片２２ａ，２２ａが、両足場板本体６，６の対向側端面８，８の夫々下端縁部８ｏ，８ｏ又は両半割足場板本体６ａ，６ａの対向側端面９，９の夫々下端縁部９ｏ，９ｏに一旦係止すれば、足場板５を撤去しない限り、隙間Ｓ₁又は隙間Ｓ₂から簡単には離脱し得ない状態となるから、使用上きわめて安全である。
【００２１】
図１１は更に他の隙間カバー３０を示す。この隙間カバー３０は、カバー本体３１と、このカバー本体３１を保持するための両側一対の保持脚部３２，３２とからなるもので、両保持脚部３２，３２は、図示のようにカバー本体３１の下面から漸次外開き状となるように突設されていて、各保持脚部３２の外側面に隙間カバー長手方向に延びる係止用爪条３２ａが上部複数段に形成されている。従って、両保持脚部３２，３２の下端部側を、互いに内側へ近づくように弾性変形させた状態で両足場板本体６，６間の隙間Ｓ₁に突入するように押し込めば、両保持脚部３２，３２の係止用爪条３２ａが、両足場板本体６，６の対向する側端面８，８に係止して、カバー本体３１を両足場板本体６，６間に架け渡した状態に確実に保持することができる。
【００２２】
【発明の効果】
請求項１に係る発明の隙間カバーは、横方向に隣合う両足場板本体に跨がって上方から架け渡されて隙間を被うカバー本体と、隙間に突入するようにカバー本体の下面に突設され、両足場板本体の側端所要部に係止してカバー本体を両足場板本体間に架け渡された状態に保持する両側一対の保持脚部と、からなるため、この隙間カバーを、足場用建枠の横材間に複数枚の足場板を横方向に並列状態に架け渡した場合に形成される隙間、又は足場用建枠の横材間に足場板を架け渡した時にその足場板を形成する２枚の半割板体の側端部間に形成されている隙間に装着することによって、隙間からのボルト・ナット等の部品や工具の落下を防止できると共に、作業者が隙間に足を引っ掛けて転んでしまうおそれがなくなり、作業上の安全を確保できる。また、隙間カバーを装着するには、保持脚部を隙間に突入するように押し込んで、カバー本体の幅方向両端部を両足場板本体に跨がって支持させるだけでよいから、装着作業も簡単容易である。
【００２３】
請求項２に係る発明によれば、両側一対の保持脚部が、両足場板本体の対向する側端面に弾性係止するように形成されているから、カバー本体を両足場板本体間に架け渡した状態に確実に保持できると共に、隙間に対する隙間カバーの装着及び取り外しが容易となる。
【００２４】
請求項３に係る発明によれば、両保持脚部が両足場板本体の対向する側端面の夫々下端縁部に係止する係止部片を備えているから、両保持脚部の鉤形係止部片が、両足場板本体の対向側端面の夫々下端縁部に係止すれば、足場板を撤去しない限り、隙間から離脱し得ない状態となるから、使用上極めて安全である。

BACKGROUND OF THE INVENTION
The present invention relates to a scaffold plate gap cover for closing a gap between side end portions of a scaffold plate spanned between transverse members of opposing scaffold building frames in a temporary framework scaffold that is framed at a construction work site. .
[0002]
[Prior art]
FIG. 12 shows a part of a temporary frame scaffold scaffolded at the construction work site. Each scaffold building frame 1 includes a pair of longitudinal members 3 and 3 and a transverse member 2 connecting the longitudinal members 3 and 3. , 2 and the reinforcing members 4, 4, and added to a plurality of upper and lower stages. The scaffolding plate 5 comprises a scaffolding plate body 6 made of a metal plate and locking hooks 7 and 7 projecting from both ends thereof. Two scaffolding plates 5 are bridged in parallel between the horizontal members 1 and 2 in the horizontal direction to form a working path.
[0003]
[Problems to be solved by the invention]
As described above, when the scaffolding plate 5 is bridged in a laterally parallel state between the transverse members 2 and 2 of the scaffolding frame 1, 1, the locking hook 7 that is locked to the transverse member 2 from the opposite direction, 7, a gap S is inevitably formed between the side end portions of the two scaffold plates 5 and 5 that are adjacent to each other in the lateral direction. If such a gap S exists in the work passage, when a metal fitting or tool such as a bolt or nut is accidentally dropped from the gap S, the metal fitting or tool hits an operator who is working in a similar work passage below. There is a risk of injury, and if there is a gap S in the work path, the operator may get caught in the gap S and fall down.
[0004]
Further, the ordinary scaffold board 5 is composed of a scaffold board body 6 having a width of 500 mm and a length of about 1600 mm. The scaffold board body 6 has two sheets having a width of 250 mm as schematically shown in FIG. The side plates of the half plates 6a, 6a are joined to each other, but for the scaffold plates that have been used for a long time, the two half plates are spaced apart by about 20 mm in the lateral direction. Some are formed by connecting the two together. In such a scaffold plate, since the same gap as the gap S is already formed in each scaffold plate itself, the same problem as described above occurs. In addition, in the example shown in FIG. 12, the clearance gap S is about 25 mm between the side edge parts of both the scaffolding plates 5 and 5 adjacent to a horizontal direction.
[0005]
In view of the above-described problems of the present invention, a scaffold board gap that can reliably and reliably close a gap formed between the side ends of the scaffold board spanned between the cross members of the scaffolding frame. The purpose is to provide a cover. Here, the gap formed between the side edges of the scaffolding board refers to the gap formed when a plurality of scaffolding boards are bridged in a parallel state between the transverse members of the scaffolding frame. In addition, a gap formed between the side end portions of the two halved plates forming the scaffold plate when the scaffold plate is bridged between the cross members of the scaffold building frame is also included.

Accordingly, when mounting the gap cover 20 in the gap S ₁ or the gap S ₂ , when the both holding legs 12, 12 are to be inserted into the gap S ₁ or the gap S ₂ , both hook-shaped locking part pieces 22 a, 22 a are used. Since the lower end surface of the taper serves as an intrusion guide, both the holding leg portions 22 and 22 are pushed down from the gap S ₁ or the gap S ₂ as they are and pushed in, as in the case of the gap cover 10. The holding leg portions 22 and 22 are elastically deformed in the direction in which the lower end portions close to each other, so that both the holding leg portions 22 and 22 can easily enter the gap S ₁ or the gap S ₂ .
[0019]
Thus, the side end surfaces 8,8 of the gap S ₁ or the gap S hook locking piece 22a of the two holding legs 22, 22 has entered a _2, 22a are both scaffolding plate body 6,6 as shown in FIG. 10 By engaging with the lower end edges 8o, 8o, respectively, or by engaging with the lower end edges 9o, 9o of the side end faces 9, 9 of the halved scaffold plate bodies 6a, 6a as shown in FIG. The holding legs 22 and 22 are elastically restored to the parallel state as shown in FIG. 8, and the cover main body 21 is bridged between the two scaffolding plate main bodies 6 and 6 or between the two half-split scaffolding plate main bodies 6a and 6a. It can be reliably held in a state.
[0020]
In the gap cover 20, the hook-shaped locking pieces 22a and 22a of the holding legs 22 and 22 are respectively connected to the lower end edges 8o and 8o of the opposite side end surfaces 8 and 8 of the scaffolding plate bodies 6 and 6, or both halves. split scaffolding plate body 6a, 6a of the opposite end surfaces 9 of the respective lower edge 9o, once the locking to 9o, unless removing the scaffolding board 5, separated as easily from the clearance S ₁ or the gap S ₂ Since it becomes a state which cannot be obtained, it is very safe in use.
[0021]
FIG. 11 shows still another gap cover 30. The gap cover 30 includes a cover main body 31 and a pair of holding leg portions 32, 32 on both sides for holding the cover main body 31, and the both holding leg portions 32, 32 are arranged as shown in the figure. A locking claw 32a extending in the longitudinal direction of the gap cover is formed on the outer surface of each holding leg 32 in a plurality of upper stages. Accordingly, the lower end of the two holding legs 32 and 32, if pushed to rush into the gap S ₁ between both scaffolding plate body 6, 6 while being elastically deformed so as to approach to the inside to each other, both holding legs The locking claws 32 a of the portions 32, 32 are locked to the opposite side end surfaces 8, 8 of the two scaffold board bodies 6, 6, and the cover body 31 is bridged between the two scaffold board bodies 6, 6. It can be reliably held in a state.
[0022]
【The invention's effect】
The gap cover of the invention according to claim 1 is formed on the lower surface of the cover main body so as to enter the gap, spanning from both sides of the scaffolding plate main bodies adjacent to each other in the lateral direction and covering the gap. This gap cover is composed of a pair of holding legs on both sides that hold the cover main body in a state of being stretched and locked to the side edge required portions of the two scaffolding plate main bodies and spanned between the two scaffolding plate main bodies. , A gap formed when a plurality of scaffolding plates are bridged in parallel in the horizontal direction between the transverse members of the scaffolding frame, or when the scaffolding plates are bridged between the transverse members of the scaffolding frame By attaching to the gap formed between the side edges of the two halved plates that form the scaffold plate, parts such as bolts and nuts and tools can be prevented from falling from the gap, and the operator There is no risk of the foot falling in the gap and ensuring work safety. That. Also, in order to attach the gap cover, it is only necessary to push the holding leg part so as to enter the gap and to support both ends of the cover body in the width direction across both scaffolding plate bodies. Easy and easy.
[0023]
According to the second aspect of the present invention, the pair of holding legs on both sides are formed so as to be elastically locked to the opposite side end surfaces of the two scaffold board main bodies, so that the cover main body is suspended between the two scaffold board main bodies. It can be securely held in the passed state, and attachment and removal of the gap cover with respect to the gap are facilitated.
[0024]
According to the invention which concerns on Claim 3, since both holding leg parts are provided with the latching | locking piece which latches to each lower end edge part of the opposing side-end surface of both scaffold board | substrate bodies, the hook shape of both holding leg parts If the locking part piece is locked to the respective lower end edge portions of the opposite side end surfaces of the two scaffolding plate bodies, it will be in a state in which it cannot be detached from the gap unless the scaffolding plate is removed, which is extremely safe in use.
