表面に粉塵層を有する既設壁体に施工し、粉塵層から発
生する粉塵の飛散を防止する隠蔽方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for spraying asbestos on a surface, such as a layer, etc.
The present invention relates to a concealment method that is applied to an existing wall having a dust layer on its surface to prevent scattering of dust generated from the dust layer.
［従来の技術］
昨今、石綿粉塵の発がん性が社会問題と成り、その防止
策として、石綿層に塗膜剤を吹付けて被膜層を作り、そ
の粉塵の飛散を防止していた。[Prior Art] Recently, the carcinogenicity of asbestos dust has become a social problem, and as a preventive measure, a coating agent has been sprayed onto the asbestos layer to form a coating layer to prevent the dust from scattering.
［発明が解決しようとする課題］
しかし、従来工法では、塗膜剤の吹付時に粉塵が飛散し
易く、作業員の健康に悪影響を及ぼすことがあるばかり
でなく、被膜層が薄いので、破損したり摩耗し易く、こ
の破損乃至は摩耗箇所から建物内に粉塵が飛散すること
があるという問題点があった。[Problems to be solved by the invention] However, with the conventional method, dust is easily scattered when the coating agent is sprayed, which not only has a negative impact on the health of workers, but also has a thin coating layer that may cause damage. There was a problem in that the parts were easily worn out and dust could be scattered into the building from the damaged or worn parts.
そこで、本発明は、上記問題点を解決するものであって

Even if vibrations are applied by a drill or the like when drilling holes for bolts, the worker is not exposed to dust, and the presser plate can be safely fixed.
［実 施 例］
以下に本発明を図面に示した一実施例に基づき説明する
。[Example] The present invention will be described below based on an example shown in the drawings.
図中、ｌは石綿の吹付層２を下面に有する既設の壁とし
ての天井壁を、３は粘着層４により吹付層２の下面に接

板、６は押え板５を固定するボルトを夫々示す。In the figure, 1 is a ceiling wall as an existing wall with a sprayed layer 2 of asbestos on the lower surface, 3 is a sheet material bonded to the lower surface of the sprayed layer 2 by an adhesive layer 4, and 5 is a sheet material that extends over the surface of the sheet material 3. The holding plate 6 indicates bolts for fixing the holding plate 5, respectively.
」−記シート材３は、耐火性を有し、好ましくは耐火性
に加えて、吸音・断熱性を有する、例えば発泡ポリエチ
レン製の比較的薄い方形の板材を使用し、ある程度可撓

ものに限らず、アルミ箔等を使用してもよい。The sheet material 3 has fire resistance, preferably a relatively thin rectangular plate made of foamed polyethylene, which has sound absorption and heat insulation properties in addition to fire resistance, and has some degree of flexibility. Things are good. Further, the sheet material 3 is not limited to a foamed material, and may be made of aluminum foil or the like.

層２の表面で硬化することで、石綿粉塵の飛散防止効果
も同時に期待することができる。The adhesive layer 4 is made of a water-permeable adhesive (for example, a mixed resin such as an acrylic resin and a latex resin),
When fixing the sheet material 3, a relatively thick adhesive may be applied to the back surface of the sheet material 3, and the adhesive surface may be bonded to the surface of the sprayed asbestos layer 2, or a similar adhesive may be applied to the back surface of the sheet material 3. After applying an adhesive in advance, a release paper (not shown) may be pasted on the adhesive surface, and the release paper may be peeled off and bonded at the site, and the latter structure is adopted here. Alternatively, the adhesive in a solution state may be applied or sprayed onto the surface of the sprayed layer 2 of asbestos, and the sheet material 3 may be applied or bonded to the coated or sprayed surface. The reason why the adhesive is made water permeable is to infiltrate the asbestos sprayed layer 2 and harden its surface to strengthen the adhesive force. By curing on the surface of the sprayed layer 2, the effect of preventing scattering of asbestos dust can be expected at the same time.
前記押え板５は、アルミニュウムで押出し成形した長尺

る。The presser plate 5 is a long flat plate extruded from aluminum, but of course it may be made of other metals or may be made of wood. Further, at the corner between the ceiling wall 1 and the side wall 7, a corner metal fitting 8, which is a long angle member, is used.
次に施工手順を説明すると、先ずシート材３の裏紙（図

層２の表面に接合する。Next, to explain the construction procedure, first peel off the backing paper (not shown) etc. of the sheet material 3 and apply the adhesive surface to the sprayed layer 2 of the ceiling wall 1.
Press and adhere to the surface of. As a result, the adhesive slightly penetrates into the asbestos spray layer 2 and joins the back surface of the sheet material 3 to the surface of the spray layer 2.
次いで、隣接するシート材３を接合する際には、第１図

中、前後方向の継ぎ目がある場合にも、同様にその端部
の一部重ね合せながら接着する。Next, when joining adjacent sheet materials 3, as shown in FIG. Then, while partially overlapping the ends of the sheet material 3 (II) to be joined next, apply the sprayed layer 2.
Press and adhere to the surface of. In this way, the next sheet material 3 (m...) is adhered in sequence over the entire surface of the sprayed layer 2 (FIG. 2). Furthermore, even if there is a seam between adjacent sheet materials 3 in the front-rear direction in the figure, they are bonded together while partially overlapping their ends.

ト材３をその可撓性を利用してコーナに沿ってＬ字形に
屈曲させ、その他端部３′を側壁７の表面に沿わせて接

石綿粉塵の飛散を防止できる。For the sheet material 3 at the four corners of the ceiling wall l, the sheet material 3 is bent into an L shape along the corner by utilizing its flexibility, and the other end portion 3' is bent along the surface of the side wall 7. Glue together (Figure 3). This can prevent asbestos dust from scattering from the four corners of the ceiling wall l.
こうして、天井壁１の吹付層２の全表面に渡ってシート

６を打込んで固定する（第１．２図）。In this way, once the sheet materials 3 are bonded over the entire surface of the sprayed layer 2 of the ceiling wall 1, presser plates 5 are placed on the surface of each sheet material 3 at appropriate intervals vertically and horizontally in order to supplement the adhesive force of the adhesive layer 4. Pass through the sheet material 3 and blow 1 layer 2 from the bottom surface at appropriate intervals along the presser plate 5, and drive the ports 6 into the ceiling wall l to fix them (Figure 1.2). .
尚、ポルト６を打込むため際には、ドリル（図示せず）

り掛ることがなく、安全に施工作業を行なえる。In addition, when driving Porto 6, use a drill (not shown).
A hole (not shown) through which the port 6 passes must be made in the ceiling wall l using a screwdriver or the like. At that time, vibrations from the drill will be applied to the sprayed layer 2, and there is a risk that asbestos dust will be scattered.
Because asbestos dust is not sprinkled on the workers from above, construction work can be carried out safely.
尚、押え板５で不充分な場合や、天井の装飾を施したい
場合には、シート材３の下に吊り天井（図示せず）を施

なうことができる。Incidentally, if the presser plate 5 is insufficient or if it is desired to decorate the ceiling, a suspended ceiling (not shown) may be constructed under the sheet material 3. In this way, even when constructing a suspended ceiling, the work can be carried out safely because the sheet material 3 is laid down first.
又、天井壁ｌの四隅にあっては、第３図に示す様に、Ｌ

んだポルト６で固定する。Also, at the four corners of the ceiling wall L, as shown in Figure 3,
The corner fitting 8 bent in the shape is made to cross between the front and rear sheets 3 in a series, and one horizontal piece 8a of the corner fitting 8 is passed through the sheet material 3 and the sprayed layer 2 to form a ceiling. Fix it with the port 6 driven into the wall 1, and attach the other vertical piece 8
b is fixed with a port 6 driven into the side wall 7 by passing through the other end 3' of the sheet material 3.
尚、図面に示した実施例では、天井壁１にシート材３を
接合してか、室内や屋外の側壁に石綿が吹付けであれば
１、その壁面に対しシート材３を接合ればよい。In the embodiment shown in the drawings, it is sufficient to join the sheet material 3 to the ceiling wall 1, or if asbestos is sprayed onto a side wall indoors or outdoors, the sheet material 3 may be joined to the wall surface. .
