Description

本発明は、各種の建設工事に用いられるシートに関し、特に建築工事中に発生するVOC(揮発性有機化合物 Volatile Organic Compounds)への対策を施した建設工事用シートおよび建設現場におけるVOCの発散抑制方法に関する。   TECHNICAL FIELD The present invention relates to a sheet used for various construction works, and more particularly to a construction work sheet in which measures against VOC (Volatile Organic Compounds) generated during construction work are taken, and a VOC divergence suppression method at a construction site. About.

従来より、例えば事務所ビルやマンションなどの新築工事、および外壁等の改修工事などの建設現場において、多くの有害なVOC(アセトアルデヒド、トルエン、トリクロロエチレン、テトラクロロエチレン、ホルムアルデヒド、ベンゼン、キシレンなどの様々な揮発性有機化合物)を含有する塗料、接着剤、防水材などの建材が使用されており、このような建材からVOCが周辺環境に発散するという問題が生じている。特に室内環境の高気密化により、建材から発生するVOC汚染は、シックハウス症候群などの居住者の健康に障害を及ぼすことにより、社会問題として捉えられている。   Conventionally, many harmful VOCs (acetaldehyde, toluene, trichloroethylene, tetrachloroethylene, formaldehyde, benzene, xylene, etc.) have been generated at construction sites such as new constructions such as office buildings and condominiums, and renovations of outer walls. Building materials such as paints, adhesives, waterproofing materials, and the like containing a conductive organic compound) are used, and there is a problem that VOCs diverge from the building materials into the surrounding environment. In particular, VOC pollution generated from building materials due to high air-tightness of the indoor environment has been regarded as a social problem by affecting the health of residents such as sick house syndrome.

しかし、上述のようなVOCの防止策として、低含有VOC建材を使用することが望ましいが、施工性および建材強度等の物性確保などにより、VOCを含有する溶剤系薬剤の使用が必要となっている。また、一般に塗料、接着剤などから揮発して拡散したVOCは処理する対策がないのが現実である。
一方、新築工事、および外壁等の改修工事などの建設現場では、建物躯体または建物の周囲を建設工事用シートで覆い、工事で発生する塵埃の周囲への拡散を抑制するようにしている(例えば、特許文献1、特許文献2)。
特開2000−303699 特開2004−162497
However, as a measure for preventing VOC as described above, it is desirable to use a low-content VOC building material, but it is necessary to use a solvent-based chemical containing VOC for securing physical properties such as workability and building material strength. Yes. Further, in general, there is no measure for treating VOCs that are volatilized and diffused from paints, adhesives, and the like.
On the other hand, at construction sites such as new construction work and renovation work such as outer walls, the building frame or the periphery of the building is covered with a construction work sheet to suppress the diffusion of dust generated in the work to the surroundings (for example, Patent Document 1, Patent Document 2).
JP 2000-303699 A JP-A-2004-162497

本発明は、従来から使用されている建設工事用シートに着目して案出されたものであって、本発明は、建築工事中に発生するVOCの影響を軽減できる建設工事用シートおよび建設現場におけるVOCの発散抑制方法を提供することを目的とする。   The present invention has been devised by paying attention to a conventionally used construction sheet, and the present invention relates to a construction sheet and a construction site that can reduce the influence of VOCs generated during construction work.

光触媒として、例えば、二酸化チタン微粒子や酸化亜鉛などの金属化合物が用いられ、本実施例では二酸化チタン微粒子を用いている。
シート本体10には、建築工事用養生シートやブルーシートと呼ばれる従来の市販品である建設工事用シート2が用いられる。
この種のシートは、一般に塩化ビニルやポリプロピレンなどのポリマーを主成分として、縦数m(例えば1.8〜5m程度)×横数m(例えば1.8〜5m程度)のサイズで、厚さ0.1〜1mm程度の方形シート状のものが利用されており、これをシート本体として用いている。
建設工事用シート2の市販品としては、例えば明治商工株式会社製の商品名「防炎シート(建築工事用養生シート)」や荻原工業株式会社製の商品名「ブルーシート」を用いることができる。なお、「防炎シート(建築工事用養生シート)」は厚みが0.3mmであり、「ブルーシート」は厚みが0.26mmである。
Hereinafter, specific examples of the present invention will be described.
FIG. 1 is a partial sectional view showing a construction work sheet 2 according to a first embodiment of the present invention.
The construction work sheet 2 of the present embodiment has a VOC processing functional film 20 containing a photocatalyst on both surfaces of a non-transparent, non-breathable sheet body 10, for example.
As the photocatalyst, for example, metal compounds such as titanium dioxide fine particles and zinc oxide are used, and titanium dioxide fine particles are used in this embodiment.
The sheet body 10 is a construction sheet 2 which is a conventional commercial product called a building curing sheet or a blue sheet.
This type of sheet is generally composed of a polymer such as vinyl chloride or polypropylene as the main component and has a length of m (for example, about 1.8 to 5 m) x a width of m (for example, about 1.8 to 5 m) and a thickness. A rectangular sheet of about 0.1 to 1 mm is used, and this is used as a sheet body.
As a commercial product of the construction sheet 2, for example, a trade name “flameproof sheet (curing sheet for building construction)” manufactured by Meiji Shoko Co., Ltd. or a trade name “Blue Sheet” manufactured by Ebara Industries Co., Ltd. can be used. . Note that the “flameproof sheet (curing sheet for building construction)” has a thickness of 0.3 mm, and the “blue sheet” has a thickness of 0.26 mm.

また、光触媒は可視光領域に近い紫外線(波長390nm程度)により活性を示すので、VOC処理機能膜20の構成材料に紫外線を通過する材料(例えばテトラフルオールエチレン)を用いることで、建物や建物躯体に臨む建設工事用シート2の内面においてまたは内面および外面の両面においてVOCの処理が可能となる。
なお、本実施例ではシート本体10の両面にVOC処理機能膜20を設けたが、VOC処理機能膜20を片面だけに設けたものであってもよい。また、シート本体10も非透明、非通気性のものに限定されず、必要に応じて適宜変更が可能なものとする。

In addition, since the photocatalyst is activated by ultraviolet rays (wavelength of about 390 nm) close to the visible light region, a material that passes ultraviolet rays (for example, tetrafluoroethylene) is used as a constituent material of the VOC processing functional film 20, thereby building or building VOC processing can be performed on the inner surface of the construction work sheet 2 facing the housing or on both the inner surface and the outer surface.
In this embodiment, the VOC processing function film 20 is provided on both surfaces of the sheet body 10, but the VOC processing function film 20 may be provided only on one side.

シート本体30は、ポリマ等よりなる繊維材を用いたものであり、市販品としては、例えば明治商工株式会社製の商品名「ソフトメッシュa」を用いることができる。
なお、「ソフトメッシュa」は、目会いが1mmであり、材質はポリプロピレンである。
VOC処理機能膜40は、アパタイト、珪藻土、シェラック樹脂などのVOC吸着作用を有する化合物と光触媒とを混合した混合物を、各種溶剤(例えば、水溶液)を用いてシート本体30に固着するようにする。
第2の実施例では、光およびVOCが通過するメッシュ状のシート本体30を用い、シート本体30をその厚さ方向に貫通する多数の隙間Sを有するので、シート本体30の両面でVOCの処理が可能となる。
なお、本実施例においても、シート本体30の構成材料に紫外線を通過する材料(例えばテトラフルオールエチレン)を用いることで、建物や建物躯体に臨む建設工事用シート2の内面においてVOCの処理が可能となる。
FIG. 2 is a partial sectional view showing a construction work sheet 2 according to a second embodiment of the present invention.
The construction work sheet 2 of this embodiment is obtained by fixing a VOC treatment functional film 40 containing a photocatalyst (for example, titanium dioxide fine particles) to the fibers of a mesh-like sheet main body 30 made of a fiber material.
The sheet body 30 uses a fiber material made of a polymer or the like, and as a commercial product, for example, a trade name “Soft Mesh a” manufactured by Meiji Shoko Co., Ltd. can be used.
The “soft mesh a” has a 1 mm mesh size and is made of polypropylene.
The VOC treatment functional film 40 is made to adhere to the sheet body 30 with a mixture of a compound having a VOC adsorption action such as apatite, diatomaceous earth, shellac resin and a photocatalyst using various solvents (for example, an aqueous solution).
In the second embodiment, a mesh-like sheet body 30 through which light and VOC pass is used, and since there are a large number of gaps S penetrating the sheet body 30 in the thickness direction, VOC processing is performed on both surfaces of the sheet body 30. Is possible.
