Description

【0001】
【発明の属する技術分野】
この発明は、鉄筋コンクリート躯体を構築するときに鉄筋の上に載置して、コンクリート打設作業時や通路等として用いる樹脂製足場マットに関する。
【0002】
【従来の技術】
スラブに鉄筋を配筋後、スラブ鉄筋上を直接作業者が歩行するとスペーサーを転倒させて鉄筋を荒らしたり、鉄筋に足を引っかけて転倒する危険性があるので直接スラブ鉄筋上を作業者が歩行することは問題がある。
【0003】
そのため従来では、例えば幅が0.3メートル×4メートルの鋼製または木製の足場板を敷設することで通路を確保していたが、この足場板では重量が重く作業性が悪く、また平板な材料のため配筋の荒れやスペーサーの転倒など真下の配筋の様子が分からなかった。
【0004】
【発明が解決しようとする課題】
そこで、作業の進行に合わせ軽く移動が容易で真下が見える金網製のマットで、大きさが0.5メートル×2メートルで、網目の大きさが0.1メートル×0.05メートルのものが使用され始めた。この金網製のマットは、薄暗い工事現場においては、スラブ鉄筋と見分けにくいといった問題が生じた。また、どこに、金網製のマットによる通路があるのか一目でわかるようにしなければならなくなった。そのため、金網製のマットに塗装をして使用しているが、その塗装作業が非常に困難であるにもかかわらず、スラブ鉄筋とこすれると塗装がすぐにはげてしまい、使用中に鉄筋との見分けが付きにくくなり再塗装しなければならないといった問題が生じた。
【0005】
また、金網製のマットに所有者のユーザー名がペンキ等で付されるが、ユーザー名を別途に付すことは面倒であり、使用によってペンキが落ちてしまう等の問題がある。
【0006】
この発明は、かかる実情に鑑みてなされたもので、製品自体に色づけをして一目でわかるようにして、薄暗い工事現場の中でも遠くから見て一目で設置位置がわかるような色の付いた樹脂製足場マットを提供することを目的とし、また樹脂とした場合でもスラブ鉄筋との間で滑ることを簡単な構成で防止することが可能な樹脂製足場マットを提供することを目的としている。
【0007】
【課題を解決するための手段】
前記課題を解決し、かつ目的を達成するために、この発明は、以下のように構成した。
【0008】
請求項1に記載の発明は、『色づけをした樹脂で一体形成した矩形形状の樹脂製足場マットであり、矩形板状の格子を有し、前記格子の複数の交点部の両面側に、円形突起を格子表面より突出して設けたことを特徴とする樹脂製足場マット。』である。
【0009】
この請求項1に記載の発明によれば、原材料自体に色づけをして一目でわかるようにしたから、鉄筋と擦れて摩耗しても薄暗い工事現場の中でも遠くから見て一目で設置位置がわかる。
【0010】
また、塗装、再塗装作業等の省力化が可能で、また、樹脂を用いたので使用後は溶かして再使用が可能となるので、産業廃棄物にならなく地球環境にやさしい。
【0011】
また、矩形板状の格子の複数の交点部の両面側円形突起を、格子表面より突出して設けたから、樹脂とした場合でも円形突起がスラブ鉄筋に引っかかり、スラブ鉄筋との間で滑ることを簡単な構成で防止することができる。
【0020】
請求項に記載の発明は、『前記樹脂製足場マットは、端部に接続部を有し、樹脂製足場マット同士を連結して使用可能であることを特徴とする請求項1記載の樹脂製足場マット。』である。
【0021】
この請求項に記載の発明によれば、樹脂製足場マット同士を連結し、工事現場などの状況に応じて接続して使用が可能であり、また分離して運搬、保管ができ、使用に便利である。
【0022】
【発明の実施の形態】
以下、この発明の樹脂製足場マットの実施の形態を、図面に基づいて説明する。図1は樹脂製足場マットの平面図、図2は樹脂製足場マットの底面図、図3は樹脂製足場マットの長手方向の側面図、図4は樹脂製足場マットの幅方向の側面図、図5は接続側の平面拡大図、図6は非接続側の平面拡大図、図7は接続側の底面拡大図、図8は非接続側の底面拡大図、図9は接続側の幅方向側面拡大図、図10は非接続側の幅方向側面拡大図、図11は図5のA−A線に沿う断面図、図12は図6のB−B線に沿う断面図、図13は図6のC−C線に沿う断面図、図14は図5のD−D線に沿う断面図、図15は図5のE−E線に沿う断面図、図16は図5のG−G線に沿う断面図、図17は図5のH−H線に沿う断面、図18は図5のK−K線に沿う断面図、図19は図5のL−L線に沿う断面図、図20は図5のM−M線に沿う断面図、図21は図5のN−N線に沿う断面図、図22は格子の拡大図、図23は樹脂製足場マット同士を連結した状態を示す図、図24は樹脂製足場マットの使用状態を示す図である。
【0023】
この実施の形態の矩形形状の樹脂製足場マット1は、色づけをした樹脂で一体形成され、矩形枠2と矩形板状の格子3とを有している。樹脂製足場マット1は、樹脂であれば顔料の配分でどんな色にも製作可能であり、樹脂としてはポリプロピレン、ポリエチレン、ポリカーボネートなどが好ましく適用可能である。
【0024】
このように、樹脂製足場マット1は、製品自体に色づけをして一目でわかるようにしたから、薄暗い工事現場の中でも遠くから見て一目で設置位置がわかる。
【0025】
また、塗装、再塗装作業等の省力化が可能で、また地球環境を考慮してリサイクル可能で産業廃棄物にならない。
【0026】
この樹脂製足場マット1は、強度及び使用の面から、形状として外形は矩形形状の矩形枠2とし、この内部を縦横格子3a,3bと斜め格子3c,3dの板状の格子3を層状としている。この矩形枠2には、軽量化のために開口2xが形成され、中央の縦格子3aにも軽量化のために開口3xが形成されている。
【0027】
縦横格子3a,3bの大きさは、例えば最大で0.2×0.15メートル、最小は0.05×0.015メートルとして作業者が樹脂製足場マット1上にのった際に、樹脂製足場マット1のどの部分にのっても、靴の一部が必ず縦横格子3a,3bのどこかに掛かるように配置している。
【0028】
また、斜め格子3c,3dは、図22に示すように、網目3eはバイブレーター50が挿入できる大きさ、例えば0.09×0.055メートルとしている。
したがって、コンクリート打設に使用する場合は、バイブレーター50の先端が網目3eから挿入でき、この網目3eが沢山開いていることで作業し易い。
【0029】
また、斜め格子3c,3dが連続する部分で、縦格子3a若しくは横格子3bとの交点部3fを、図17に示すように円柱状にし、このように円柱状にすることで、格子間の接続耐力の向上を図ることができる。
【0030】
この樹脂製足場マット1では、安全性の確保に関して、滑りを防止する必要があり、この滑りとして考えられることは、樹脂製足場マット1とスラブ鉄筋との滑りと、樹脂製足場マット1と靴との滑りの両方がある。
【0031】
まず、樹脂製足場マット1とスラブ鉄筋との滑りを防止するメカニズムであるが、樹脂製足場マット1の置き方には次のような場合が考えられる。
【0032】
図24に示すように、スラブの上端筋51と樹脂製足場マット1の長手方向が平行な場合(図24(a))、スラブの上端筋51と樹脂製足場マット1の長手方向が直交する場合(図24(b))、樹脂製足場マット1が上端筋51に対して斜めに置かれた場合(図24(c))がある。
【0033】
この樹脂製足場マット1では、スラブ鉄筋との滑りを防止するための突起として、縦横格子3a,3b若しくは斜め格子3c,3dのある短い区間に平面突起3gを設け、この平面突起3gは樹脂製足場マット1の幅方向、長さ方向、斜め方向に対して位置を変えて断続的に配置し、少なくとも、その幅方向には、長手方向のどこかの横格子3aのどこかの位置を採れば連続するように配置する。
【0034】
また、斜め格子3c,3dが連続する部分で、縦格子3a若しくは横格子3bとの交点部3fには、図16及び図17に示すように、円柱状の接続部に円形突起3hを設けている。
【0035】
図24(a)に示すように、上端筋51と樹脂製足場マット1の長手方向が平行な場合は、各格子に設けた幅の狭い短い区間の平面突起3gが鉄筋の節と節との間に嵌まり込み樹脂製足場マット1が移動しなくなることで、滑りを防止する。
【0036】
図24(b)に示すように、上端筋51と樹脂製足場マット1の長手方向が直行する場合は、鉄筋自体のリブや節に各格子上に設けた幅の狭い短い区間の平面突起3gや格子と格子の交点の円形突起3hに当たり横に移動しなくなることで、滑りを防止する。
【0037】
図24(c)に示すように、スラブの鉄筋に対して樹脂製足場マット1が斜めに置かれた場合に関しては、上に述べた平面突起3gや円形突起3hの各突起が同様に働くことで、滑りを防止する。
【0038】
次に、樹脂製足場マット1と靴との滑りに関しては、前記した断続的な平面突起3gの他に、斜め格子3c,3dの交点部3fや縦横格子3a,3bの交点部3fに、例えば直径3ミリの小さな突起3iを多数設けることによって、さらに滑らないようにしている。
【0039】
これらの平面突起3gや円形突起3hおよび交点部突起3iの高さは、スラブ鉄筋に突起が当たってマットが滑らない高さで、なおかつ、作業者が歩行時に躓かない高さ、すなわち4ミリメートル以下で1.0ミリメートル以上に設計した、より好ましくは2.5から1.5ミリメートルがよい。また、樹脂製足場マット1は使用上、表裏関係なく使用するので、表裏両面に同一の突起を設けたほうがよい。
【0040】
この樹脂製足場マット1は、原材料に顔料を混ぜることによって、その物自体に色を付けることで、鉄筋との擦れ等で落ちる塗装とは異なり、使用頻度が高くても薄暗い工事現場の遠くからでも通路がどこにあるか明確に分かる。また、工事終了後のメンテナンスでの再塗装作業の省力化を図ることができる。
【0041】
また、材料に樹脂を用いても所々に突起を設けたので、その突起が鉄筋の節若しくはリブに当たり樹脂製足場マット1が鉄筋に対して移動を阻止し、作業者の踏み付けでも靴の滑りをも防止することにより作業の安全性を確保することができる。
【0042】
また、樹脂製足場マット1は、樹脂を使用したことにより、鉄と比べてコンクリートの付着が悪いので、コンクリート打設作業後のケレン作業の低減を図れるので、樹脂製足場マット1として優れている。そして、摩耗その他で使用不能となった場合にも再度溶かしてリサイクルが可能なので産業廃棄物にならず、地球環境の保全と作業環境の安全に配慮した樹脂製足場マット1が得られる。
【0043】
また、樹脂製足場マット1は樹脂製なので、図6に示すように、、矩形枠2の表側にユーザー名53を型により一体的に鋳込み入れられるので、大きな現場での多数の工事業者が樹脂製足場マット1の同一製品を持ち込んでも、所有者の識別が可能となる。また、業者毎に、樹脂製足場マット1の色を変えることで識別することも可能となるので、現場からの回収手間がよい。また、樹脂製足場マット1の矩形枠2の側面側には、図10に示すように、製造年月を示す年マーク54、月マーク55及びユーザーマーク56を入れることができる。
【0044】
また、樹脂製足場マット1は、長手方向の一端に着脱可能な接続部3kを有する。この接続部3kは、一方の外側から内側に形成された図18に示す接続凸部3k1、図21に示す接続凹部3k2、図20に示す接続凸部3k3と、他方の外側から内側に形成された図19に示す接続凹部3k4、図20に示す接続凸部3k3、図21に示す接続凹部3k2とから構成される。
【0045】
図18に示す接続凸部3k1は係合突起3k11を有し、図19に示す接続凹部3k4は係合孔部3k41を有し、この接続凸部3k1と接続凹部3k4は着脱可能に構成され、係合突起3k11が係合孔部3k41に係合して連結される。図20に示す接続凸部3k3は係合凸部3k31を有し、図21に示す接続凹部3k2は係合孔部3k21を有し、この接続凸部3k3と接続凹部3k2は着脱可能に構成され、係合凸部3k31が係合孔部3k21に係合して連結される。
【0046】
この樹脂製足場マット1は、図23に示すように、樹脂製足場マット1同士を、一方の接続部3kと他方の接続部3kとで、接続凸部3k1と接続凹部3k4とを挿着し、接続凸部3k3と接続凹部3k2とを挿着して連結する。
【0047】
このように樹脂製足場マット1同士を工事現場などの状況に応じて使用可能であり、また接続部3kを長手方向の両端に設ければ、使用したい長さに接続が可能となり、敷き並べた間に隙間が生じなく、作業者がスムースに移動が可能であり、また分離して運搬、保管ができ、使用に便利である。
【0048】
また、樹脂製足場マット1の各格子は、縦形の形状として、面の部分を持たないものとしたが、曲げ剛性を高めるために、表面の裏表に互い違いに長手方向に面を設定してもよい。
【0049】
また、格子は、縦横格子と斜め格子の複合構造には限定されず、縦横格子のみ、若しくは斜め格子のみでもよい。
【0050】
さらに、樹脂製足場マット1は、樹脂製の場合は、全体が0.5メートル×2メートルと大きいので、半分の大きさの0.5メートル×1メートルの金型として、2個を中心で接続して1枚ものとしてもよい。
【0051】
また、樹脂製足場マット1は、デザイン的にも優れているので、工事現場では、簡易のフェンスとしても使用が可能である。また、工事現場以外でも、芝生用のマット、家庭用の玄関マット、園芸用のフェンス等、美観を求められるような場所に使われるマットやフェンスとしても使用が可能である。
【0052】
【発明の効果】
前記したように、請求項1に記載の発明では、原材料自体に色づけをして一目でわかるようにしたから、鉄筋と擦れて摩耗しても薄暗い工事現場の中でも遠くから見て一目で設置位置がわかる。
【0053】
また、塗装、再塗装作業等の省力化が可能で、また、樹脂を用いたので使用後は溶かして再使用が可能となるので、産業廃棄物にならなく地球環境にやさしい。
【0054】
また、矩形板状の格子の複数の交点部の両面側円形突起を、格子表面より突出して設けたから、樹脂とした場合でも突起がスラブ鉄筋に引っかかり、スラブ鉄筋との間で滑ることを簡単な構成で防止することができる。
【0060】
請求項に記載の発明では、樹脂製足場マット同士を連結し、工事現場などの状況に応じて接続して使用が可能であり、また分離して運搬、保管ができ、使用に便利である。

BACKGROUND OF THE INVENTION
The present invention relates to a resin scaffold mat that is placed on a reinforcing bar when constructing a reinforced concrete frame and used as a concrete placing work or as a passage.
[0002]
[Prior art]
After the reinforcing bars are placed on the slab, if the worker walks directly on the slab reinforcing bars, the spacer may fall down to roughen the reinforcing bars, or there is a risk of falling over by pulling the legs on the reinforcing bars, so the worker walks directly on the slab reinforcing bars. There is a problem to do.
[0003]
Therefore, in the past, for example, a passage was secured by laying a steel or wooden scaffolding plate having a width of 0.3 m × 4 meters. However, this scaffolding plate is heavy and has poor workability, and is flat. Because of the material, I didn't know how the bar arrangement was underneath, such as the rough arrangement of the bar and the fall of the spacer.
[0004]
[Problems to be solved by the invention]
Therefore, a wire netting mat that is light and easy to move as the work progresses and can be seen directly below, has a size of 0.5 meters x 2 meters, and a mesh size of 0.1 meters x 0.05 meters. Began to be used. This wire mesh mat has a problem that it is difficult to distinguish it from a slab rebar in a dark construction site. It was also necessary to be able to see at a glance where there was a passage made of wire mesh mats. For this reason, a wire mesh mat is used for painting, but the painting work is very difficult, but if it is rubbed with a slab rebar, the paint will be peeled off quickly, and the rebar will be damaged during use. There was a problem that it was difficult to distinguish and it had to be repainted.
[0005]
In addition, although the owner's user name is given to the wire mesh mat with paint or the like, it is troublesome to give the user name separately, and there is a problem that the paint is dropped due to use.
[0006]
The present invention has been made in view of such circumstances, and is colored resin so that the installation position can be seen at a glance from a distance even in a dark construction site so that the product itself can be colored and understood at a glance. Ltd. scaffold mat is intended to provide a hand that aims at providing a resin scaffold mat can be prevented with a simple structure that the slipping between the slab rebar even if the resin.
[0007]
[Means for Solving the Problems]
In order to solve the above-described problems and achieve the object, the present invention is configured as follows.
[0008]
The invention according to claim 1 is “a rectangular resin scaffolding mat integrally formed with colored resin, having a rectangular plate-like lattice, and circular on both sides of a plurality of intersections of the lattice. A resin scaffold mat, characterized in that protrusions are provided so as to protrude from the lattice surface. ].
[0009]
According to the first aspect of the present invention, since the raw material itself is colored so that it can be seen at a glance, even if it is worn by rubbing against a reinforcing bar, the installation position can be seen at a glance even in a dimly lit construction site. .
[0010]
In addition, it is possible to save labor for painting and repainting work, etc. Also, since resin is used, it can be melted and reused after use, so it does not become industrial waste and is friendly to the global environment.
[0011]
In addition, since the circular protrusions are provided on both sides of the plurality of intersections of the rectangular plate-shaped grid so as to protrude from the grid surface, the circular protrusion can be caught by the slab rebar and slipped between the slab rebars even when resin is used. This can be prevented with a simple configuration.
[0020]
The invention according to claim 2, "the resin scaffold mat has a connection to the end, according to claim 1, characterized in that it is usable by connecting the resin scaffold mats Resin scaffold mat. ].
[0021]
According to the invention of claim 2 , the resin scaffold mats can be connected to each other and used according to the situation such as the construction site, and can be transported and stored separately. Convenient.
[0022]

[0023]
The rectangular resin scaffold mat 1 of this embodiment is integrally formed of colored resin, and has a rectangular frame 2 and a rectangular plate-like lattice 3. As long as the resin scaffold mat 1 is a resin, it can be produced in any color by pigment distribution, and polypropylene, polyethylene, polycarbonate, or the like is preferably applicable as the resin.
[0024]
Thus, since the resin scaffold mat 1 is colored on the product itself so that it can be seen at a glance, the installation position can be seen at a glance from a distance even in a dim construction site.
[0025]
In addition, labor saving such as painting and repainting work is possible, and it is recyclable in consideration of the global environment and does not become industrial waste.
[0026]
This resin scaffold mat 1 has a rectangular frame 2 having a rectangular outer shape in terms of strength and use, and the inside thereof is formed into a layered plate-like lattice 3 of vertical and horizontal lattices 3a and 3b and oblique lattices 3c and 3d. Yes. An opening 2x is formed in the rectangular frame 2 for weight reduction, and an opening 3x is also formed in the central vertical lattice 3a for weight reduction.
[0027]
The vertical and horizontal lattices 3a and 3b have a size of, for example, a maximum of 0.2 × 0.15 meters and a minimum of 0.05 × 0.015 meters, and when the worker gets on the resin scaffold mat 1, the resin Regardless of which part of the scaffolding mat 1 is placed, a part of the shoe is always placed somewhere on the vertical and horizontal grids 3a, 3b.
[0028]
Further, as shown in FIG. 22, in the diagonal lattices 3c and 3d, the mesh 3e has a size that allows the vibrator 50 to be inserted, for example, 0.09 × 0.055 meters.
Therefore, when used for placing concrete, the tip of the vibrator 50 can be inserted from the mesh 3e, and the mesh 3e is open so that it is easy to work.
[0029]
In addition, in the portion where the diagonal lattices 3c and 3d are continuous, the intersection 3f with the vertical lattice 3a or the horizontal lattice 3b is formed into a columnar shape as shown in FIG. Connection strength can be improved.
[0030]
In the resin scaffold mat 1, it is necessary to prevent slipping in order to ensure safety, and what is considered as this slip is slipping between the resin scaffold mat 1 and the slab rebar, resin scaffold mat 1 and shoes. There is both sliding and.
[0031]
First, there is a mechanism for preventing slippage between the resin scaffold mat 1 and the slab rebar, but the following cases are conceivable for placing the resin scaffold mat 1.
[0032]
As shown in FIG. 24, when the longitudinal direction of the upper end reinforcement 51 of the slab and the resin scaffolding mat 1 are parallel (FIG. 24A), the longitudinal direction of the upper end reinforcement 51 of the slab and the longitudinal direction of the resin scaffolding mat 1 are orthogonal to each other. In some cases (FIG. 24B), the resin scaffold mat 1 may be placed obliquely with respect to the upper end line 51 (FIG. 24C).
[0033]
In this resin scaffold mat 1, planar protrusions 3 g are provided in a short section having vertical and horizontal lattices 3 a and 3 b or diagonal lattices 3 c and 3 d as protrusions for preventing slippage with the slab reinforcing bars, and the planar protrusions 3 g are made of resin. The scaffold mat 1 is intermittently arranged with its position changed with respect to the width direction, the length direction, and the oblique direction, and at least the position of the horizontal lattice 3a in the longitudinal direction can be taken in the width direction. If so, arrange them to be continuous.
[0034]
Further, as shown in FIGS. 16 and 17, circular protrusions 3h are provided at the connecting portions 3f at the intersections 3f with the vertical lattice 3a or the horizontal lattice 3b in the portion where the diagonal lattices 3c and 3d are continuous. Yes.
[0035]
As shown in FIG. 24 (a), when the longitudinal direction of the upper end bars 51 and the resin scaffolding mat 1 are parallel to each other, the flat projections 3g of the narrow short sections provided in the respective grids are formed between the bars of the reinforcing bars. The resin scaffold mat 1 fitted in between is prevented from moving, thereby preventing slipping.
[0036]
As shown in FIG. 24 (b), when the longitudinal direction of the upper end bars 51 and the resin scaffolding mat 1 are perpendicular to each other, the flat projections 3g of the narrow and short sections provided on the respective ribs and nodes of the reinforcing bars themselves on the lattices. Further, slipping is prevented by not moving laterally by hitting the circular protrusion 3h at the intersection of the lattice and the lattice.
[0037]
As shown in FIG. 24 (c), in the case where the resin scaffold mat 1 is placed obliquely with respect to the slab reinforcing bars, the above-described planar projections 3g and circular projections 3h work in the same manner. To prevent slipping.
[0038]
Next, regarding the slip between the resin scaffold mat 1 and the shoes, in addition to the above-described intermittent planar protrusion 3g, the intersection 3f of the diagonal lattices 3c and 3d and the intersection 3f of the vertical and horizontal lattices 3a and 3b are, for example, By providing a large number of small protrusions 3i having a diameter of 3 mm, it is further prevented from slipping.
[0039]
The heights of the flat projections 3g, the circular projections 3h, and the intersection projections 3i are such that the mats do not slide due to the projections hitting the slab reinforcing bars, and the height at which the operator does not crawl when walking, that is, 4 mm or less. Designed to 1.0 mm or more, more preferably 2.5 to 1.5 mm. In addition, since the resin scaffold mat 1 is used regardless of the front and back in use, it is preferable to provide the same protrusions on both the front and back sides.
[0040]
This resin scaffold mat 1 is different from the paint that falls due to rubbing against the reinforcing bars by coloring the material itself by mixing the pigment with the raw material, but it is far away from the dark construction site even if it is used frequently. But you can clearly see where the passage is. In addition, it is possible to save labor in repainting work after maintenance work.
[0041]
Also, even if resin is used as the material, since the protrusions are provided in some places, the protrusions hit the reinforcing bar nodes or ribs, and the resin scaffold mat 1 prevents the movement relative to the reinforcing bars, so that even if the operator steps on, the shoes slip. By preventing this, it is possible to ensure the safety of work.
[0042]
Further, the resin scaffold mat 1 is excellent as the resin scaffold mat 1 because the adhesion of concrete is worse than that of iron due to the use of the resin, and therefore the kelen work after the concrete placing work can be reduced. . And even if it becomes unusable due to wear or the like, it can be melted again and recycled, so that it does not become industrial waste, and the resin scaffold mat 1 that takes into consideration the preservation of the global environment and the safety of the work environment can be obtained.
[0043]
Also, since the resin scaffold mat 1 is made of resin, as shown in FIG. 6, a user name 53 can be integrally cast into the front side of the rectangular frame 2 by a mold, so that many construction contractors on a large site can use resin. Even if the same product of the scaffolding mat 1 is brought in, the owner can be identified. Moreover, since it becomes possible to identify by changing the color of the resin-made scaffold mats 1 for every contractor, the collection effort from the field is good. Further, as shown in FIG. 10, a year mark 54, a month mark 55, and a user mark 56 indicating the date of manufacture can be placed on the side surface side of the rectangular frame 2 of the resin scaffold mat 1.
[0044]
The resin scaffold mat 1 has a detachable connecting portion 3k at one end in the longitudinal direction. The connecting portion 3k is formed from one outer side to the inner side, the connecting convex portion 3k1 shown in FIG. 18, the connecting concave portion 3k2 shown in FIG. 21, the connecting convex portion 3k3 shown in FIG. 20, and the other outer side to the inner side. 19 includes a connection recess 3k4 shown in FIG. 19, a connection protrusion 3k3 shown in FIG. 20, and a connection recess 3k2 shown in FIG.
[0045]
The connection projection 3k1 shown in FIG. 18 has an engagement protrusion 3k11, the connection recess 3k4 shown in FIG. 19 has an engagement hole 3k41, and the connection projection 3k1 and the connection recess 3k4 are configured to be detachable. The engagement protrusion 3k11 is engaged with and connected to the engagement hole 3k41. The connection convex part 3k3 shown in FIG. 20 has an engagement convex part 3k31, and the connection concave part 3k2 shown in FIG. 21 has an engagement hole part 3k21. The connection convex part 3k3 and the connection concave part 3k2 are configured to be detachable. The engaging protrusion 3k31 is engaged with and connected to the engaging hole 3k21.
[0046]
As shown in FIG. 23, the resin scaffold mat 1 is formed by inserting the resin scaffold mats 1 with each other between the connection projection 3k1 and the connection recess 3k4 at one connection portion 3k and the other connection portion 3k. The connecting projection 3k3 and the connecting recess 3k2 are inserted and connected.
[0047]
In this way, the resin scaffold mats 1 can be used according to the situation at the construction site and the like, and if the connecting portions 3k are provided at both ends in the longitudinal direction, the connection can be made to the length to be used, and they are laid out. There is no gap between them, the operator can move smoothly, and can be transported and stored separately, which is convenient for use.
[0048]
In addition, each lattice of the resin scaffolding mat 1 has a vertical shape and does not have a surface portion. However, in order to increase the bending rigidity, surfaces may be alternately set in the longitudinal direction on both sides of the surface. Good.
[0049]
The lattice is not limited to a composite structure of vertical and horizontal lattices and diagonal lattices, and may be only vertical and horizontal lattices or only oblique lattices.
[0050]
Furthermore, since the resin scaffold mat 1 is made of resin and the whole is as large as 0.5 m × 2 meters, the mold is half the size of 0.5 m × 1 meter, and two of them are centered. It is good also as one sheet by connecting.
[0051]
Further, since the resin scaffold mat 1 is excellent in design, it can be used as a simple fence at a construction site. In addition, it can be used as a mat or fence used in places where aesthetics are required, such as a mat for lawn, a doormat for home use, a fence for horticulture, etc. even outside the construction site.
[0052]
【The invention's effect】
As described above, in the invention according to claim 1, since the raw material itself is colored so that it can be seen at a glance, even if it is worn by rubbing against a reinforcing bar, the installation position can be seen at a glance even in a dark construction site. I understand.
[0053]
In addition, it is possible to save labor for painting and repainting work, etc. Also, since resin is used, it can be melted and reused after use, so it does not become industrial waste and is friendly to the global environment.
[0054]
In addition, since circular protrusions are provided on both sides of the intersections of the rectangular plate-shaped grids so as to protrude from the grid surface, even when resin is used, the protrusions can easily catch on the slab rebar and slide between them. Can be prevented with a simple configuration.
[0060]
In the invention according to claim 2 , the resin scaffold mats are connected to each other and can be connected and used according to the situation such as the construction site, and can be separated and transported and stored, which is convenient for use. .
