Description

本発明は、構造物表面の剥落防止工法に関するものであり、詳しくは、トンネルの天井や壁あるいは橋桁などの構造物の表面に補強塗料をスプレー塗布して補強膜を形成する構造物表面の剥落防止工法に関するものである。   TECHNICAL FIELD The present invention relates to a method for preventing a structure surface from peeling off. More specifically, the structure surface is formed by spraying a reinforcing paint on the surface of a structure such as a tunnel ceiling, wall or bridge girder to form a reinforcing film. This relates to the prevention method.

トンネルの天井や壁あるいは橋桁など、表面がコンクリートやモルタルで構成された構造物においては、表面材料の剥落を防止するため、定期的な補修工事として剥落防止工事を行う必要がある。剥落防止工法としては、例えば、トンネルの覆工コンクリートや吹付けコンクリートの剥離箇所またはその可能性の高い箇所に対し、イソシアネート成分とポリアミン成分とから成る硬化型ポリウレア系樹脂を補強塗料としてスプレー塗布し、前記の剥離箇所などの表面に補強膜を形成する「コンクリート片の剥離剥落箇所の補修法」が提案されている。上記の工法は、構築物表面にパネルを付設したり、樹脂を含浸させた繊維を敷設する方法に比べ、点検しながら、必要に応じて逐次施工できるため、効率的でコスト的にも有利である。
特開2004−218352号公報
In structures such as tunnel ceilings, walls, or bridge girders whose surfaces are made of concrete or mortar, it is necessary to perform anti-peeling work as a regular repair work to prevent the surface material from peeling off. As a method for preventing exfoliation, for example, a curable polyurea resin composed of an isocyanate component and a polyamine component is spray-applied as a reinforcing paint to a peeling part of tunnel lining concrete or shotcrete or a highly likely place. In addition, a “repair method for peeling and peeling off a concrete piece” has been proposed in which a reinforcing film is formed on the surface of the peeling point or the like. Compared to the method of attaching panels to the surface of the structure or laying fibers impregnated with resin, the above construction method can be applied sequentially as needed while checking, so it is efficient and advantageous in terms of cost. .

本発明において、スプレー塗布される補強塗料としては、熱硬化型の樹脂を主成分とする塗料、具体的には、2液混合型のエポキシ樹脂、ウレタン樹脂、ウレア樹脂、ポリメタクリル酸メチル(PMMA)等から成る塗料が使用される。上記のエポキシ樹脂としては、ビスフェノールA型エポキシ樹脂、ビスフェノールF型エポキシ樹脂、フェノールノボラック型エポキシ樹脂、クレゾールノボラック型エポキシ樹脂、環状脂肪族エポキシ樹脂、グリシジルエステル系樹脂、グリシジルアミン系樹脂、複素環式エポキシ樹脂が挙げられ、中でも、コスト面からビスフェノールA型エポキシ樹脂が好ましい。   In the present invention, the reinforcing paint to be applied by spraying is a paint mainly composed of a thermosetting resin, specifically, a two-component mixed epoxy resin, urethane resin, urea resin, polymethyl methacrylate (PMMA). ) Etc. are used. Examples of the epoxy resin include bisphenol A type epoxy resin, bisphenol F type epoxy resin, phenol novolac type epoxy resin, cresol novolac type epoxy resin, cyclic aliphatic epoxy resin, glycidyl ester resin, glycidyl amine resin, heterocyclic type An epoxy resin is mentioned, and among them, a bisphenol A type epoxy resin is preferable from the viewpoint of cost.

更に、上記の樹脂は、金属粉を含有していてもよい。すなわち、上記の補強塗料によって形成される補強膜には、金属粉が含まれていてもよい。また、2液の混合は、後述するスプレーガン(21)(図1参照)で行われるか、または、スプレーガン(21)への供給前に塗料容器内で行われる。そして、上記の補強塗料によって形成される補強膜は、吹付け量によってその厚さを調節されるが、通常、補強膜の厚さは0.1〜5mm、好ましくは0.5〜3mmとされる。   Further, the above resin may contain a metal powder. That is, the reinforcing film formed by the above reinforcing paint may contain metal powder. Further, the mixing of the two liquids is performed with a spray gun (21) (see FIG. 1) to be described later, or is performed in a paint container before being supplied to the spray gun (21). The thickness of the reinforcing film formed by the above-mentioned reinforcing paint is adjusted by the amount of spraying. Usually, the thickness of the reinforcing film is 0.1 to 5 mm, preferably 0.5 to 3 mm. The

本発明においては、施工性を高め且つ補強塗料の周辺への飛散を防止するため、図1に示す様に、取扱いが容易なブース(1)を使用してスプレー塗布を行う。すなわち、本発明においては、スプレー塗布する際、ブース(1)によって施工部分を覆い、フィルター(31)を備えた排風設備(3)(図2参照)を使用してブース(1)内の空気を排気することにより、ブース(1)内に飛散する補強塗料を回収する。   In the present invention, in order to improve workability and prevent scattering of the reinforcing paint to the periphery, spray coating is performed using a booth (1) that is easy to handle as shown in FIG. That is, in the present invention, when spray coating is performed, the construction part is covered by the booth (1), and the inside of the booth (1) is used using the exhaust air facility (3) (see FIG. 2) provided with the filter (31). By exhausting the air, the reinforcing paint scattered in the booth (1) is collected.

ブース(1)としては、施工部分を覆うことが出来かつ簡便に移動できる構造のものであれば特に制限はないが、トンネル(6)の天井や橋桁上部などの高所を施工するため、斯かるブース(1)は、図2及び図3に示す様に、例えば、自走式の高所作業車(4)の昇降可能な作業台(5)に設けられる。なお、本発明において、高所作業車としては、作業台を昇降させる装置を備えたもの又は備えていないものの何れでもよい。   The booth (1) is not particularly limited as long as it has a structure that can cover the construction part and can be moved easily, but in order to construct high places such as the ceiling of the tunnel (6) and the upper part of the bridge girder, As shown in FIGS. 2 and 3, the booth (1) is provided, for example, on a work table (5) capable of moving up and down of a self-propelled aerial work platform (4). In the present invention, the aerial work vehicle may be either equipped with or not equipped with a device for raising and lowering the work table.

ブース(1)は、図1に示す様に、例えば水平断面が方形に形成され且つ上端が開放された筒状のいわゆる蛇腹(11)と、当該蛇腹の下端を封止する底板(12)で構成される。蛇腹(11)は、通常、樹脂製シートによって構成され、斯かるシートの材料としては、尿素樹脂、フェノール樹脂、不飽和ポリエステル樹脂、ポリウレア、ポリウレタン、アルキド樹脂、エポキシ樹脂、メラミン樹脂などが挙げられる。取扱い性および耐久性の観点からは、ポリウレア、ポリウレタン、または、ポリウレアとポリウレタンの混合物が好ましい。   As shown in FIG. 1, the booth (1) includes, for example, a cylindrical so-called bellows (11) having a horizontal cross section formed in a square shape and an open upper end, and a bottom plate (12) that seals the lower end of the bellows. Composed. The bellows (11) is usually constituted by a resin sheet, and examples of the material of the sheet include urea resin, phenol resin, unsaturated polyester resin, polyurea, polyurethane, alkyd resin, epoxy resin, and melamine resin. . From the viewpoint of handleability and durability, polyurea, polyurethane, or a mixture of polyurea and polyurethane is preferable.

底板(12)は、通常、樹脂製または金属製の板材で構成される。底板(12)の材料としては、樹脂製の場合、製作が容易であることから、通常は蛇腹(11)と同様の材料が使用される。また、金属製の場合は、鉄、アルミニウム、鉄とアルミニウムの複合体などが使用され、積載荷重の観点からは、鉄、鉄とアルミニウムの複合体が好ましい。勿論、高所作業車(4)の作業台(5)の床板が穴のない板材で構成されている場合はこれを利用してもよい。   The bottom plate (12) is usually made of a resin or metal plate. As the material of the bottom plate (12), in the case of resin, it is easy to manufacture, and therefore the same material as that of the bellows (11) is usually used. In the case of a metal, iron, aluminum, a composite of iron and aluminum, etc. are used, and from the viewpoint of the load capacity, a composite of iron, iron and aluminum is preferable. Of course, when the floor board of the work platform (5) of the aerial work vehicle (4) is made of a plate material without holes, this may be used.

ブース(1)は、上記の様に蛇腹(11)で構成されていることにより、高さ調整が可能であり、また、車幅方向に沿った蛇腹(11)の側面に折込みが設けられ且つ底板(12)が折畳み可能に構成されていることにより、幅方向に伸縮させることも出来る。すなわち、ブース(1)は、上記の折込みが設けられていることにより、広さの調整も可能である。特に、高所作業車(4)の作業台(5)が車幅方向に拡張可能な構造を備えている場合には、高所作業車(4)の幅を拡げた際にブース(1)の内部も当該作業台に応じて広くすることが出来る。   The booth (1) is configured by the bellows (11) as described above, so that the height can be adjusted, and a fold is provided on the side surface of the bellows (11) along the vehicle width direction. Since the bottom plate (12) is configured to be foldable, it can be expanded and contracted in the width direction. That is, the booth (1) can be adjusted in size by providing the above folding. In particular, when the work platform (5) of the aerial work vehicle (4) has a structure that can be expanded in the vehicle width direction, the booth (1) The interior of the can also be widened according to the work table.

ブース(1)は作業台(5)に固定されていても、固定されていなくてもよいが、蛇腹(11)の上端部を支持する伸縮自在な支柱(13)が底板(12)に取り付けられていることにより、支柱(13)の高さ調節により、蛇腹(11)の高さ(ブース内の高さ)を作業に適した高さに設定することが出来る。なお、ブース(1)の大きさは、通常、長さが1000〜5000mm程度、幅が1000〜5000mm程度、高さが1000〜5000mm程度とされる。   The booth (1) may or may not be fixed to the workbench (5), but an extendable column (13) that supports the upper end of the bellows (11) is attached to the bottom plate (12). Therefore, the height of the bellows (11) (the height in the booth) can be set to a height suitable for work by adjusting the height of the support column (13). The size of the booth (1) is usually about 1000 to 5000 mm in length, about 1000 to 5000 mm in width, and about 1000 to 5000 mm in height.

図示しないが、補強塗料の塗布を行うための塗布機は、主に、塗料容器、塗料吐出用のコンプレッサー、スプレーガン(21)、および、塗料容器などからスプレーガン(21)へ至るホース(22)から構成され、これらは、通常、高所作業車(4)の作業台(5)基部の近傍に搭載される。また、塗布機は、高所作業車(4)とは別の車両に搭載されてもよい。   Although not shown, an applicator for applying the reinforcing paint mainly includes a paint container, a paint discharge compressor, a spray gun (21), and a hose (22) from the paint container to the spray gun (21). These are usually mounted in the vicinity of the work table (5) base of the aerial work vehicle (4). The applicator may be mounted on a vehicle different from the aerial work vehicle (4).

前述した様に、スプレーガン(21)で2液を混合する場合、上記のホース(22)としては、コンプレッサーからスプレーガン(21)へ至る圧縮空気用のホース、A液(主剤)の容器からスプレーガンへ至るホース、および、B液(硬化剤)の容器からスプレーガンへ至るホースの3本が使用される。また、塗料容器内で2液を混合する場合は、加圧された塗料容器からスプレーガン(21)へ至る1本のホース、あるいは、コンプレッサーからスプレーガン(21)へ至る圧縮空気用のホースと塗料容器からスプレーガン(21)へ至るホースの2本のホースが使用される。   As described above, when the two liquids are mixed with the spray gun (21), the hose (22) includes a hose for compressed air from the compressor to the spray gun (21), and a container for the liquid A (main agent). Three hoses are used: a hose leading to the spray gun, and a hose leading from the B liquid (curing agent) container to the spray gun. When mixing two liquids in the paint container, one hose from the pressurized paint container to the spray gun (21) or a hose for compressed air from the compressor to the spray gun (21) Two hoses are used, the hose leading from the paint container to the spray gun (21).

上記のブース(1)は、図1及び図2に示す様に、フィルター(31)を備えた排風設備(3)により、内部の空気を排気可能に構成され、塗布時にブース(1)内で飛散する補強塗料のミストをフィルター(31)に回収する様になされている。具体的には、図2に示す様に、排風設備(3)は、例えば、作業台(5)の後方の荷台部に搭載されたフィルター(31)及びブロワー(32)と、ブース(1)からフィルター(31)まで伸長され且つその少なくとも一部が蛇腹で構成された伸縮自在なダクト(33)とから構成される。   As shown in FIG. 1 and FIG. 2, the booth (1) is configured to be able to exhaust the internal air by the exhaust air facility (3) provided with the filter (31). The filter (31) collects the mist of the reinforcing paint that scatters in the filter. Specifically, as shown in FIG. 2, the air exhaust facility (3) includes, for example, a filter (31) and a blower (32) mounted on the loading platform behind the work table (5), and a booth (1 ) To the filter (31), and at least a part thereof is composed of a telescopic duct (33) composed of bellows.

図4に示す様に、本発明の剥落防止工法により例えばトンネル(6)の天井を補修する場合は、先ず、補修箇所の直下に高所作業車(4)を配置した後、作業台(5)を上昇させ、そして、ブース(1)の上端が天井に略接する程度に蛇腹(11)を引き伸ばし、ブース(1)によって施工部分を覆う。その場合、図1に示す様に、ブース(1)内に外気を取り込み且つ他の施工箇所へ簡単に移動し得る様に、天井のコンクリート面とブース(1)の上端との間に数cm程度の隙間を開けておく。次いで、補強塗料を塗布するに当たり、排風設備(3)を稼働させ、ブース(1)内の空気を排気する。続いて、塗布機を作動させ、スプレーガン(21)に補強塗料を供給してスプレー塗布を行う。   As shown in FIG. 4, when repairing the ceiling of a tunnel (6), for example, by the peeling prevention method of the present invention, first, after placing an aerial work vehicle (4) directly under the repaired location, a work table (5 The bellows (11) is stretched so that the upper end of the booth (1) is substantially in contact with the ceiling, and the construction part is covered with the booth (1). In that case, as shown in FIG. 1, several cm between the concrete surface of the ceiling and the upper end of the booth (1) so that outside air can be taken into the booth (1) and easily moved to other construction sites. Leave a certain gap. Next, when applying the reinforcing paint, the air exhaust facility (3) is operated, and the air in the booth (1) is exhausted. Subsequently, the coating machine is operated, and the reinforcing paint is supplied to the spray gun (21) to perform spray coating.

本発明の剥落防止工法では、取扱い容易なブース(1)により補修部分を簡単に覆うことが出来る。そして、フィルター(31)を備えた排風設備(3)によってブース(1)内の空気を排気することにより、作業中は常時ブース(1)内を負圧に保持し、ブース(1)内の空気と共に補強塗料のミストをフィルター(31)に捕捉する。従って、スプレー塗布の際に発生する塗料ミストの周囲への飛散を確実に防止することが出来る。   In the peeling prevention method according to the present invention, the repaired portion can be easily covered by the booth (1) which is easy to handle. And by exhausting the air in the booth (1) by the exhaust system (3) provided with the filter (31), the inside of the booth (1) is always kept at a negative pressure during the work, and the inside of the booth (1) The mist of the reinforcing paint is trapped in the filter (31) together with the air. Accordingly, it is possible to reliably prevent the paint mist from being scattered around the spray application.

すなわち、本発明によれば、足場を組む等の大掛かりな養生が不要であり、補修部分にブース(1)をあてがうだけで直ちに塗布作業を行うことが出来、より効率的に工事を進めることが出来る。また、特に、トンネル(6)内などの路上における工事では、高所作業車(4)を駐車するだけであるから、全車線の通行を規制する必要がなく、簡便に工事を遂行できる。そして、上記の様に、排風設備(3)ににより確実に塗料ミストを回収するため、補強塗料の飛散による二次被害を防止することが出来る。   That is, according to the present invention, a large-scale curing such as building a scaffold is unnecessary, the application work can be performed immediately by simply attaching the booth (1) to the repaired part, and the construction can be carried out more efficiently. I can do it. In particular, in the construction on the road such as in the tunnel (6), since the aerial work vehicle (4) is merely parked, it is not necessary to restrict the passage of all lanes, and the construction can be easily performed. And as mentioned above, since paint mist is reliably collect | recovered by the exhaust apparatus (3), the secondary damage by scattering of a reinforcing paint can be prevented.
