Description

本発明は、建物の塗装工事現場で用いられる塗料ミスト飛散防止用シート及びその展張方法に関する。   The present invention relates to a paint mist scattering prevention sheet used at a building construction site of a building and a method for spreading the same.

従来、塗装工事現場の外周には作業上の危険防止および塗料ミストおよび粉塵の外部飛散防止に合成樹脂製の養生用メッシュシートが展張されるのが通例である。しかしながら、メッシュシートは通気性を有するので、塗料ミストおよび粉塵の一部が空気流と共に外部に飛散して環境悪化問題をおこし、養生用メッシュシートの目的を十分満足できるものではなかった。   Conventionally, a curing mesh sheet made of a synthetic resin is usually spread on the outer periphery of a painting construction site to prevent work hazards and to prevent external scattering of paint mist and dust. However, since the mesh sheet has air permeability, a part of the paint mist and dust is scattered to the outside together with the air flow to cause an environmental deterioration problem, and the purpose of the curing mesh sheet is not sufficiently satisfied.

そこで、ポリオレフィン系樹脂からなる粗目を有する網状体をエレクトレット化し、塗料ミストおよび粉塵の補集効率を向上せしめた塗料ミスト飛散防止用メッシュシートが開発された。このシートは、ポリオレフィン系樹脂１００重量部に対し、フェノール系安定剤、イオウ系安定剤またはリン系安定剤から選ばれた少なくとも１種を０．０１〜２重量部を配合した樹脂組成物からなる延伸糸条から形成された粗目を有する網状体であって、該網状体の表面をコロナ放電処理によりエレクトレット化したものである（特許文献１参照）。
特開平９−１１７６９９号公報（第２頁） Accordingly, a mesh sheet for preventing paint mist from scattering has been developed in which a mesh-like body made of polyolefin resin is electretized to improve the efficiency of collecting paint mist and dust. This sheet consists of a resin composition in which 0.01 to 2 parts by weight of at least one selected from a phenol-based stabilizer, a sulfur-based stabilizer or a phosphorus-based stabilizer is blended with 100 parts by weight of a polyolefin-based resin. A mesh-like body formed from stretched yarn and having a coarse texture, and the surface of the mesh-like body is electretized by corona discharge treatment (see Patent Document 1).
JP-A-9-117699 (page 2)

従来のエレクトレット化してその帯電現象を利用して塗料ミストを補集するシートでは、シートの製造コストが高くなり、しかも張設されたシート間に隙間ができれば、その隙間からミストが通過してしまうものであった。   In the case of a sheet that collects paint mist using the electret phenomenon by utilizing the electrification phenomenon, the manufacturing cost of the sheet increases, and if there is a gap between the stretched sheets, the mist passes through the gap. It was a thing.

そこで、本発明は、低コストで塗料ミストの飛散を防止できる塗料ミスト飛散防止用シート及びその展張方法を提供することを目的とする。   Therefore, an object of the present invention is to provide a paint mist scattering prevention sheet that can prevent paint mist from scattering at low cost and a method for spreading the same.

上述の目的を達成するため、本発明のシートは、塗装工事現場において足場を形成する縦単管を所定間隔で立設し、これら隣り合う縦単管間にメッシュシートを張設し、これらメッシュシートの外周に張設される塗料ミスト飛散防止用シートであって、横幅を縦単管間の間隔の２倍ないし６倍プラス６０〜８０ｃｍに形成された不織布からなり、隣り合う不織布同士はその両端部が３０〜４０ｃｍオーバーラップした状態で張設されているものである。また、シートの展張方法は、塗装工事現場の外周に展張される塗料ミスト飛散防止用シートの展張方法であって、足場を形成するために作られ所定幅の対向する縦単管にラッセル網で形成されたメッシュシートをハトメ孔を通して連結展張し、これを１ユニットとして繰り返し、建築物外周をメッシュシートで囲い、次に、該メッシュシートの建築物と対向しない反対側の面に重ねて不織布を展張する工程で、該不織布の両端部を縦単管より（６０〜８０ｃｍ）／２を横方向に残してメッシュシートのｎ個（ｎは２〜６）のユニットを跨いで展張し、その端部（６０〜８０ｃｍ）／２は隣り合う不織布の端部とオーバーラップして展張しているものである。   In order to achieve the above-mentioned object, the sheet of the present invention has vertical single pipes standing at predetermined intervals in a painting construction site, and mesh sheets are stretched between these adjacent vertical single pipes. It is a sheet for preventing paint mist from spreading on the outer periphery of the sheet, and is composed of a non-woven fabric having a width that is 2 to 6 times the interval between vertical single tubes plus 60 to 80 cm. Both ends are stretched with an overlap of 30 to 40 cm. In addition, the sheet is spread out on the outer periphery of the paint construction site by spreading a sheet for preventing paint mist from splashing. The formed mesh sheet is connected and stretched through eyelet holes, this is repeated as one unit, the outer periphery of the building is surrounded by the mesh sheet, and then the nonwoven fabric is laminated on the opposite surface of the mesh sheet not facing the building. In the step of stretching, the both ends of the nonwoven fabric are stretched across n units (n is 2 to 6) of the mesh sheet, leaving (60 to 80 cm) / 2 in the horizontal direction from the longitudinal single tube, The part (60 to 80 cm) / 2 is extended and overlapped with the end of the adjacent nonwoven fabric.

本発明は、塗装工事現場において足場を形成する縦単管を所定間隔で立設し、これら隣り合う縦単管間にメッシュシートを張設し、これらメッシュシートの外周に張設される塗料ミスト飛散防止用シートであって、横幅を縦単管間の間隔の２倍ないし６倍プラス６０〜８０ｃｍに形成された不織布からなり、隣り合う不織布同士はその両端部が３０〜４０ｃｍオーバーラップした状態で張設されているので、不織布が塗料ミストの飛散を防止し、しかも不織布の端部をオーバーラップさせてあるので、シート間に隙間ができず、飛散防止が確実なものとなる。また、シートをエレクトレット化する必要もなく、安価な不織布で十分な効果を上げることができる。また、足場を形成するために作られ所定幅の対向する縦単管にラッセル網で形成されたメッシュシートをハトメ孔を通して連結展張し、これを１ユニットとして繰り返し、建築物外周をメッシュシートで囲い、次に、該メッシュシートの建築物と対向しない反対側の面に重ねて不織布を展張する工程で、該不織布の両端部を縦単管より（６０〜８０ｃｍ）／２を横方向に残してメッシュシートのｎ個（ｎは２〜６）のユニットを跨いで展張し、その端部（６０〜８０ｃｍ）／２は隣り合う不織布の端部とオーバーラップして展張しているので、メッシュシート間の隙間やメッシュシートの通気部分からの塗料ミストの飛散が防止でき、しかも不織布の横幅がメッシュシートの２〜６倍プラス６０〜８０ｃｍであるために、展張作業も効率良く行える。   The present invention relates to a paint mist that is provided with vertical single pipes that form a scaffold at a painting construction site at predetermined intervals, a mesh sheet is stretched between the adjacent vertical single pipes, and is stretched around the outer periphery of the mesh sheets. It is a sheet for preventing scattering, and is made of a nonwoven fabric whose lateral width is 2 to 6 times the interval between vertical single tubes plus 60 to 80 cm, and adjacent nonwoven fabrics are overlapped by 30 to 40 cm at both ends. Since the non-woven fabric prevents the paint mist from scattering and the ends of the non-woven fabric are overlapped, there is no gap between the sheets, and the prevention of scattering is ensured. Moreover, there is no need to electretize the sheet, and a sufficient effect can be achieved with an inexpensive non-woven fabric. In addition, a mesh sheet made of russell nets is formed on the opposing vertical single tubes of a predetermined width to form a scaffold, and connected and stretched through eyelet holes, and this is repeated as one unit, and the outer periphery of the building is surrounded by the mesh sheet. Next, in the step of spreading the nonwoven fabric on the opposite side of the mesh sheet that is not opposed to the building, both ends of the nonwoven fabric are left in the horizontal direction (60-80 cm) / 2 from the longitudinal single tube. The mesh sheet is stretched across n units (n is 2 to 6) of the mesh sheet, and its end (60 to 80 cm) / 2 is stretched so as to overlap with the end of the adjacent nonwoven fabric. The paint mist can be prevented from splashing from the gaps between the mesh sheet and the ventilation part of the mesh sheet, and the width of the nonwoven fabric is 2 to 6 times that of the mesh sheet plus 60 to 80 cm. Obtain.

以下に、本発明の実施形態について、図面を参照にして説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１及び図２において、塗装工事現場において組み立てられた足場の縦単管１を所定間隔、現状は１８０ｃｍ間隔で立設し、建物側に面してこの縦単管１間にラッセル網で形成されたメッシュシート２を張設してある（図２参照）。これらメッシュシート２の外周、すなわち建物に向き合った側とは反対側に不織布からなる塗料ミスト飛散防止用シート３を張設する。このシート（不織布）３は、その横幅を縦単管１間の間隔の２倍ないし６倍プラス６０〜８０ｃｍに形成してある。この実施形態では、縦単管１の間隔を１８０ｃｍとしたので、「１８０ｃｍ×３＋６０ｃｍ」の横幅とした。上記「倍数」は、作業の効率面などから２〜６倍とするのが好ましい。   1 and 2, the vertical single pipes 1 of the scaffold assembled at the painting construction site are erected at a predetermined interval, currently 180 cm apart, and are formed with a Russell network between the vertical single pipes 1 facing the building side. The mesh sheet 2 is stretched (see FIG. 2). A paint mist scattering prevention sheet 3 made of a nonwoven fabric is stretched on the outer periphery of the mesh sheet 2, that is, the side opposite to the side facing the building. This sheet (nonwoven fabric) 3 is formed so that its lateral width is 2 to 6 times the interval between the vertical single tubes 1 plus 60 to 80 cm. In this embodiment, since the interval between the vertical single tubes 1 is 180 cm, the horizontal width is “180 cm × 3 + 60 cm”. The “multiple” is preferably 2 to 6 times from the viewpoint of work efficiency.

図１に示すシート（不織布）３は、横幅が６００ｃｍ（６ｍ）、縦の長さが６４８ｃｍに形成されるとともに、両端部の上下４箇所にハトメ孔４を形成し、両端部から夫々３０ｃｍ内側に上下の縦方向に亘って５ケのハトメ孔４を等間隔で形成し、これらから内側に夫々１８０ｃｍ離れた位置の上下の縦方向にも５ケのハトメ孔４を形成してある。これらのハトメ孔４には縦単管１に連結するための紐（図示せず）が固定され、これらの紐でシート（不織布）３を縦単管１に取付けて、シート（不織布）３を展張する。図１に示すシート（不織布）３に形成された縦方向５ケのハトメ孔４の個所が縦単管１に位置され、隣り合うシート（不織布）３同士は、３０〜４０ｃｍ、この実施形態では両端部で３０ｃｍオーバーラップした状態で展張される。   The sheet (nonwoven fabric) 3 shown in FIG. 1 has a width of 600 cm (6 m) and a vertical length of 648 cm, and has eyelet holes 4 at the upper and lower portions of both ends, and 30 cm inside from both ends. In addition, five eyelet holes 4 are formed at equal intervals in the upper and lower vertical directions, and five eyelet holes 4 are also formed in the upper and lower vertical directions at positions 180 cm away from each other. A string (not shown) for connecting to the vertical single pipe 1 is fixed to the eyelet holes 4, and a sheet (nonwoven fabric) 3 is attached to the vertical single pipe 1 with these strings to attach the sheet (nonwoven fabric) 3. Spread. 1 is located in the vertical single tube 1 and the adjacent sheets (nonwoven fabrics) 3 are 30 to 40 cm in this embodiment. It is stretched with 30cm overlap at both ends.

なお、シート（不織布）３の縦の長さは、６００〜７００ｃｍの範囲内とし、縦単管１の個所に位置すべき縦方向のハトメ孔４は、５ケに限定されるものではなく、２〜６ケが好ましく、均等間隔に形成される。   In addition, the vertical length of the sheet (nonwoven fabric) 3 is in a range of 600 to 700 cm, and the vertical eyelet holes 4 to be positioned at the portions of the vertical single tube 1 are not limited to five pieces, 2-6 pieces are preferable and formed at equal intervals.

図２に示すメッシュシート２にもハトメ孔５が形成され、隣り合うメッシュシート２のハトメ孔５間を紐６で縦単管１にしばりつけてメッシュシート２を連結展張してある。図２に示すように、建築物の外周をメッシュシート２で囲い、このメッシュシート２の建築物と対向しない反対側の面に、メッシュシート２に重ねてシート（不織布）３を展張する。前記２本の縦単管１に張設されたメッシュシート２を１ユニットとしたとき、シート（不織布）３の両端部を縦単管１より（６０〜８０ｃｍ）／２を横方向に残してメッシュシート２のｎ個（ｎは２〜６）のユニットを跨いで展張し、その端部（６０〜８０ｃｍ）／２は隣り合うシート（不織布）３の端部とオーバーラップするようにしてある。また、シート（不織布）３の展張は、建築物とメッシュシート２との間に組み立てられた足場にいる人により展張されるが、（６０〜８０ｃｍ）／２の端部を折り返した位置にあるハトメ孔４に固定されている紐で縦単管１に連結し、さらに隣り合うシート（不織布）３を同様にして縦単管１に連結する。このように、シート（不織布）３の（６０〜８０ｃｍ）／２の端部の上下両端の対向するハトメ孔４同士を連結した後、左右いずれか側の縦単管１に固定する。さらに、両端部以下のハトメ孔４（図１では縦５ケのもの）は、固定されている紐で縦単管１に固定する。   Eyelet holes 5 are also formed in the mesh sheet 2 shown in FIG. 2, and the mesh sheets 2 are connected and stretched by sticking between the eyelet holes 5 of adjacent mesh sheets 2 to the vertical single tube 1 with a string 6. As shown in FIG. 2, the outer periphery of the building is surrounded by a mesh sheet 2, and a sheet (nonwoven fabric) 3 is stretched over the mesh sheet 2 on the opposite surface of the mesh sheet 2 that does not face the building. When the mesh sheet 2 stretched on the two vertical single tubes 1 is taken as one unit, both ends of the sheet (nonwoven fabric) 3 are left in the horizontal direction (60 to 80 cm) / 2 from the vertical single tube 1. The mesh sheet 2 is stretched across n units (n is 2 to 6), and its end (60 to 80 cm) / 2 overlaps with the end of the adjacent sheet (nonwoven fabric) 3. . Further, the sheet (nonwoven fabric) 3 is stretched by a person on a scaffold assembled between the building and the mesh sheet 2, but at an end of (60 to 80 cm) / 2. The string fixed to the eyelet hole 4 is connected to the vertical single tube 1, and the adjacent sheet (nonwoven fabric) 3 is connected to the vertical single tube 1 in the same manner. Thus, after connecting the eyelet holes 4 facing each other at both the upper and lower ends of the (60 to 80 cm) / 2 end of the sheet (nonwoven fabric) 3, the sheet is fixed to the vertical single tube 1 on either the left or right side. Furthermore, the eyelet holes 4 (5 vertical in FIG. 1) below both ends are fixed to the vertical single tube 1 with a fixed string.

前記メッシュシート２は、ラッセル網を用い、通気性を有し、塗料ミストを通過させるものである。塗料ミスト飛散防止用シート（不織布）３は、材料としてはナイロンやポリエステルが好適に使用される。また、合繊長繊維不織布の引裂強力（Ｎ）（Tear Strength、引き裂き強度）をベンジュラム法で測定し、３．５〜１０．０（Ｎ）であることが使用するシート（不織布）３として好適であった。このベンジュラム法とは、６．５ｃｍ×１０ｃｍの試験片を、縦、横方向に夫々５枚採取し、エレメンドル形引き裂き強さ試験機を用い、試験片の両つかみの中央で長辺のほぼ中央に辺と直角な刃物によって２ｃｍの切れ目を入れ、残り４．５ｃｍが引き裂かれたときに示す最大荷重をはかり、縦、横方向を夫々の平均値で表わす方法である。さらに、シート（不織布）３の厚みは、０．２８〜０．４６ｍｍが好適である。０．２８ｍｍ未満であると強度が不足し、０．４６ｍｍ超であると固くなりすぎて展張作業がやりにくくなる。   The mesh sheet 2 uses a Russell net, has air permeability, and allows the paint mist to pass therethrough. As the material for the paint mist scattering prevention sheet (nonwoven fabric) 3, nylon or polyester is preferably used. Moreover, the tear strength (N) (Tear Strength, tear strength) of synthetic fiber long-fiber nonwoven fabric is measured by the Benjuram method, and it is suitable as the sheet | seat (nonwoven fabric) 3 used that it is 3.5-10.0 (N). there were. The Benjuram method is a method of collecting 6.5 cm x 10 cm test pieces in the vertical and horizontal directions, and using an elemen dollar type tear strength tester. This is a method in which a 2 cm cut is made by a cutter perpendicular to the side in the center, and the maximum load shown when the remaining 4.5 cm is torn is applied, and the vertical and horizontal directions are expressed as average values. Furthermore, the thickness of the sheet (nonwoven fabric) 3 is preferably 0.28 to 0.46 mm. If it is less than 0.28 mm, the strength is insufficient, and if it is more than 0.46 mm, it becomes too hard and the stretching work becomes difficult.

養生シートの種類による塗料飛散程度と乾燥性とを比較実験してみた。養生シートとしては、ラッセル網シート（ａ）、ブルーシート（ビニールシート）（ｂ）、不織布シート（ｃ）を用いた。これら（ａ）〜（ｃ）の夫々で、ボックスの天井の一部と風を送るための側面の一部を除き、ボックスを覆った。また、ＯＨＰシートを養生シート外側、シート間の隙間、天井の隙間に設置し、側面から風を送りながら固形分６７重量％のアクリルシリコンエマルション塗料（以降、塗料Ａという）をボックスに２０分間連続塗装し（スプレーガンを用いた）、そのまま６０分間放置した。ボックス中心部の風速を約１ｍ／ｓ、ボックスの大きさを（４５０ｍｍ×９０ｍｍ×５５ｍｍ）とした。前記ＯＨＰシートに付着した塗料ミスト量を比較した。また、乾燥性の比較については、各養生シートで底面以外の５面を覆ったボックス中に塗料Ａを塗装した板を入れ、指触乾燥時間の比較を行う。このときのボックスの大きさは、７０ｍｍ×２００ｍｍ×３３０ｍｍ、気温２３℃、湿度５０％ＲＨ、無風状態とし、塗料Ａの塗布量は０．３５ｋｇ／ｍ２とした。 A comparative experiment was conducted on the degree of paint splashing and the drying property depending on the type of curing sheet. As the curing sheet, a Russell net sheet (a), a blue sheet (vinyl sheet) (b), and a nonwoven fabric sheet (c) were used. In each of these (a) to (c), the box was covered except for a part of the ceiling of the box and a part of the side surface for sending wind. In addition, an OHP sheet is installed on the outside of the curing sheet, between the sheets, and between the ceilings, and an acrylic silicone emulsion paint (hereinafter referred to as "paint A") with a solid content of 67% by weight is sent to the box for 20 minutes while sending air from the side. It was painted (using a spray gun) and left for 60 minutes. The wind speed at the center of the box was about 1 m / s, and the size of the box was (450 mm × 90 mm × 55 mm). The amount of paint mist adhering to the OHP sheet was compared. Moreover, about the comparison of drying property, the board which coated the coating material A in the box which covered 5 surfaces other than the bottom face with each curing sheet is put, and the touch drying time is compared. The size of the box at this time was 70 mm × 200 mm × 330 mm, the air temperature was 23 ° C., the humidity was 50% RH, and no wind was applied, and the coating amount of the coating material A was 0.35 kg / m 2 .

上記（ｂ）のシートでは風を全く通さないため、また（ｃ）のシートでは風を通しにくいために、塗料ミストも通過していないことが判明した。これら（ｂ）,（ｃ）のシートの飛散防止効果を「５」の評価（防止効果が高い）とすると、（ａ）のシートでは「３」の評価（防止効果が低い）であった。また、乾燥性については、（ａ）シートを○とすると、（ｂ）シートが×、（ｃ）シートが△の評価であった。評価基準は下記の通りである。
○：乾燥性良好
△：乾燥性は若干劣るが実用上問題はない
×：乾燥性不良
（ｃ）の不織布シートは、シート間の隙間から塗料ミストが多く飛散した。これは、他のシート（ａ），（ｂ）に比べて素材が柔らかいために、側面からの風で不織布シートがばたつき、隙間が一時的に広くなるためと考えられる。 The sheet (b) does not pass any air, and the sheet (c) does not easily pass air. When the scattering prevention effect of the sheets (b) and (c) was evaluated as “5” (high prevention effect), the sheet (a) was evaluated as “3” (low prevention effect). Moreover, regarding the drying property, when (a) the sheet is ◯, (b) the sheet was evaluated as x, and (c) the sheet was evaluated as Δ. The evaluation criteria are as follows.
◯: Good drying property Δ: Slightly inferior drying property, but no problem in practical use ×: Poor drying property The nonwoven fabric sheet (c) has a lot of paint mist scattered from the gaps between the sheets. This is presumably because the material is softer than the other sheets (a) and (b), so that the nonwoven fabric sheet flutters with the wind from the side surface and the gap is temporarily widened.

上述のような実験結果を踏まえて、本発明が開発され、塗料ミスト飛散を防止し、乾燥性も大きく損うこともなく、展張作業も容易になるように上述したような構成としたものである。   Based on the experimental results as described above, the present invention was developed to prevent the paint mist from scattering, the drying property is not greatly impaired, and the construction as described above is facilitated. is there.
