Description

本発明はコンクリート下地などに防水層を形成する防水工法に係り、特に既存の下地状態に左右されることなく防水層を形成することのできる機械的固定工法における防水シートの固定方法に関する。   The present invention relates to a waterproofing method for forming a waterproof layer on a concrete base or the like, and more particularly to a waterproof sheet fixing method in a mechanical fixing method capable of forming a waterproof layer without being affected by an existing base state.

防水シートのコンクリートなどからなる下地へ防水層を形成する方法は、密着工法と機械的固定工法の２種類に分けることができる。   The method of forming the waterproof layer on the foundation made of concrete or the like of the waterproof sheet can be divided into two types, an adhesion method and a mechanical fixing method.

密着工法とは、防水シートを、接着剤を用いて下地全面に貼り付けてしまう工法であり、また一方機械的固定工法とは浮かし貼り工法とも呼ばれ、防水シートを、接着剤を用いず、ボルト、ネジ又は釘などのアンカー部材により、局所的に下地に対して固定する方法である。   Adhesion method is a method of attaching a waterproof sheet to the entire surface of the base using an adhesive, while mechanical fixing method is also called floating attachment method, without using an adhesive, This is a method of locally fixing the substrate with an anchor member such as a bolt, screw or nail.

密着工法は、下地が水分を含んでいたりすると接着剤がきかないこと、また、敷設後の水分の蒸発で膨れを生じるといった、下地の状態に左右されやすい問題が有り、防水シートの下に通気溝を設けて、脱気筒より排気するなどの工夫がなされていた。   The adhesion method has a problem that the adhesive does not work if the substrate contains moisture, and the swelling of moisture after the laying has occurred. It was devised to exhaust from the de-cylinder.

そこで下地の状態に左右されない機械的固定工法が提案されている。機械的固定工法は通常、接着剤を用いていないため、下地の状態に左右されずに敷設できるとともに、局所的にしか固定されていないので、下地が水分を含んでいても下地から発生した水蒸気が排気しやすいといった利点がある。   Therefore, a mechanical fixing method that is not affected by the state of the ground has been proposed. Since the mechanical fixing method usually does not use an adhesive, it can be laid regardless of the state of the base and is fixed only locally, so even if the base contains moisture, water vapor generated from the base Has the advantage of being easy to exhaust.

しかし、下地との固定の際に防水層となるシートにアンカー部材を通す貫通孔を設けなければならないために、防水の面では完全とは言い難いという問題がある。また、防水層の貫通孔をできるだけ小さくし、しかもその孔を塞いでしまうように工夫した方法として、防水シートの素材として塩化ビニルなどの合成樹脂を用い、固定プレートとしては鋼板の表面に防水シートと同質の合成樹脂を貼り付けたものを用いて、防水シートの上から防水シートと固定プレートの間に溶剤を注射針のようなもので注入し、溶剤で防水シート及び固定プレート表面の合成樹脂を溶かすことによって溶着するといった方法が提案されている（特許文献１）。   However, since it is necessary to provide a through-hole through which the anchor member passes through a sheet that becomes a waterproof layer when fixed to the base, there is a problem that it is difficult to say that it is completely waterproof. In addition, as a method of making the through hole of the waterproof layer as small as possible and closing the hole, synthetic resin such as vinyl chloride is used as the material of the waterproof sheet, and the waterproof sheet on the surface of the steel plate as the fixing plate Injecting a solvent between the waterproof sheet and the fixing plate with something like an injection needle from the top of the waterproof sheet using a synthetic resin of the same quality as the synthetic resin on the surface of the waterproof sheet and the fixing plate with the solvent There has been proposed a method of welding by melting (Patent Document 1).

この方法では、防水シートに貫通孔を開けることには違いないが、極めて小さな孔であり、しかも、溶剤を注入することによってその孔も塞ぐことができる。   In this method, a through hole must be formed in the waterproof sheet, but it is an extremely small hole, and the hole can also be closed by injecting a solvent.

また、その他に固定プレートを熱可塑性樹脂単体で製造したものを使用したり、金属性の固定プレート本体に塩化ビニル樹脂をコーティングして、その上に重ねた同素材の塩化ビニル樹脂からなる防水シートを熱融着するといった方法も採られている。   In addition, a waterproof sheet made of a single material made of thermoplastic resin or coated with vinyl chloride resin on the metal fixed plate body and overlaid on the same is made of the same material vinyl chloride resin. The method of heat-sealing is also taken.

さらに特許文献２では上面に熱溶着材層を有する導体片を下地に固着し、その上から防水シートを重ねて防水シートの上から電磁誘導加熱することによって導体片を加熱し、熱溶着材層を融かして防水シートを熱融着するといった方法が開示されている。   Furthermore, in Patent Document 2, a conductor piece having a heat-welding material layer on the upper surface is fixed to a base, and a conductor sheet is heated by layering a waterproof sheet on top of the conductor sheet and electromagnetically heating from the top of the waterproof sheet. A method is disclosed in which the waterproof sheet is heat-sealed by melting.

上記のような熱融着による防水シートの下地への固定方法において、加熱して融着する部分を融かした後に防水シートの上から押さえつけて固定プレートに押し付ける圧着工程がある。この圧着作業としては今まで板やウエス等を介在して手や足を使って押さえたり、電磁誘導加熱器自身の重量を利用して更に人間が押さえつけることで圧着していた。   In the method of fixing the waterproof sheet to the base by heat sealing as described above, there is a pressure-bonding step in which a portion to be fused by heating is melted and then pressed from above the waterproof sheet and pressed against the fixing plate. Up to now, the crimping operation has been performed by pressing with hands and feet through a board or waste, or by further pressing by the person using the weight of the electromagnetic induction heater itself.

ところが、このような方法であると作業者によって押し付ける力に差が生じ、固定プレートに一定の圧着力を加えることが難しい。押さえつけている間は作業者が他の作業をすることができなくなるので時間的な面でも不利である。また、圧着作業自体を忘れてしまうといった問題もあった。   However, with such a method, a difference occurs in the pressing force by the operator, and it is difficult to apply a constant pressure to the fixing plate. It is also disadvantageous in terms of time because the operator cannot do other work while holding down. There is also a problem that the crimping operation itself is forgotten.

必要な圧着力を発揮することができる重量を有するブロック等の錘を用いて圧着作業をするといった方法も考えられるが、かなりの重量があって錘の移動等の取扱いが大変であるといった違う問題がある。   Although a method of crimping using a weight such as a block that has a weight that can exert the necessary crimping force is also considered, there is a different problem that there is considerable weight and handling of the weight etc. is difficult There is.

そこで本発明では防水シートの固定プレートへの圧着作業において圧着力を一定に保つことができ、且つ圧着している間にも作業者が次の融着作業等他の作業を行うことができ、また重量物の移動等を必要としない防水シートの固定方法の提供を目的とする。   Therefore, in the present invention, the crimping force can be kept constant in the crimping operation of the waterproof sheet to the fixed plate, and the operator can perform other operations such as the next fusion operation while being crimped, It is another object of the present invention to provide a waterproof sheet fixing method that does not require movement of heavy objects.

このような目的を達成するため日本発明の請求項１では、下地に防水シートを敷設し、防水シートの所要位置を下地に固定する防水シートの固定方法において、少なくとも防水シートと接する側の表面に被覆材を積層接着した導体からなる固定プレートを下地にアンカー固定し、その上から前記防水シートを重ね合わせた状態で、防水シートの上から電磁誘導加熱することによって固定プレートを加熱し被覆材を溶融させ、次いで磁石からなる圧着具を防水シート上から固定プレートに磁着させることで防水シートと固定プレート間を加圧し、両者を融着させることを特徴とする。   In order to achieve such an object, according to claim 1 of the present invention, in a waterproof sheet fixing method in which a waterproof sheet is laid on a base and a required position of the waterproof sheet is fixed to the base, at least a surface in contact with the waterproof sheet is provided. A fixing plate made of a conductor in which a covering material is laminated and bonded is anchored to a base, and the waterproof sheet is overlaid on top of the waterproof sheet. Then, a pressure bonding tool made of a magnet is magnetically attached to the fixed plate from above the waterproof sheet to pressurize between the waterproof sheet and the fixed plate, thereby fusing them together.

請求項２では、圧着具の広さは、固定プレートに重ね合わせたときに固定プレートよりも１０〜４０ｍｍ広く設定した請求項１記載の防水シートの固定方法としている。   According to a second aspect of the present invention, the width of the crimping tool is set to be 10 to 40 mm wider than the fixed plate when the crimping tool is superimposed on the fixed plate.

請求項３では、圧着具による加圧力が５〜３０ｋｇ／ｍ２である請求項１〜２記載の防水シートの固定方法としている。 According to Claim 3, the pressure applied by the crimping tool is 5 to 30 kg / m 2 .

本発明によると、電磁誘導加熱機で被覆材を溶融させた後の、防水シートの固定プレートへの圧着に、磁石からなる圧着具を用いて固定プレートへ磁着させることで磁力による圧着を行っている。よって、圧着力は一定に保つことができ、圧着作業の間も人手をかける必要がないので他の作業を並行して行うことができる。また、圧着力に磁力を利用していることから圧着具自身の重量は大きくする必要がなく、移動させるのも容易である。   According to the present invention, after the covering material is melted with an electromagnetic induction heater, the waterproof sheet is pressure-bonded to the fixed plate by using a magnet-made pressure bonding tool and magnetically bonded to the fixed plate. ing. Therefore, the crimping force can be kept constant, and other operations can be performed in parallel because there is no need for manpower during the crimping operation. In addition, since the magnetic force is used for the crimping force, it is not necessary to increase the weight of the crimping tool itself, and it is easy to move it.

以下、添付図面にしたがって本発明の具体的な実施態様を説明する。図１は、防水シートの固定方法において加熱しているところを示す断面図である。   Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a cross-sectional view showing the heating in the waterproof sheet fixing method.

加硫ゴムからなる防水シートを敷設しようとするコンクリートなどからなる下地１に、まず固定プレート２をアンカー部材３で所定間隔をもって固定配置する。配置する固定プレート２を数は、下地１の状態にもより、特に決まった数があるわけではないが、防水シート４が風などの影響で浮き上がったりしないように十分に下地１に固定される必要があり、通常１〜４個／ｍ2程度の範囲で均等に配置する。 First, a fixing plate 2 is fixedly arranged at a predetermined interval by an anchor member 3 on a base 1 made of concrete or the like to be laid with a waterproof sheet made of vulcanized rubber. The number of fixing plates 2 to be arranged is not particularly determined depending on the state of the base 1, but is sufficiently fixed to the base 1 so that the waterproof sheet 4 does not rise due to the influence of wind or the like. It is necessary to arrange them uniformly in the range of about 1 to 4 pieces / m 2 .

固定プレート２を配置したら、次に加硫ゴムからなる防水シート４をその上から覆い被せるように配置する。防水シート４は、１〜２ｍ幅のシートをジョイントし、現場の広さの防水シート４を形成し全面に配置する。   After the fixing plate 2 is disposed, the waterproof sheet 4 made of vulcanized rubber is then disposed so as to cover it. The waterproof sheet 4 is formed by jointing sheets having a width of 1 to 2 m to form a waterproof sheet 4 having a field size, and is disposed on the entire surface.

そして、固定プレート２は図２にしめすように表面は熱可塑性の被覆材で覆われており、防水シート４と重なっている部分で、防水シート４の上から電磁誘導加熱器Ｄで金属製のプレート本体５を加熱して表面に被覆材６を融解することによって防水シート４に孔を開けることなく固定プレート２を融着固定している。電磁誘導加熱により被覆材を融解した後に、防水シート上から０．０５〜５．０ＭＰａ、通常は０．０５〜０．５ＭＰａの圧力で５〜６０秒押える圧着作業を行うことによって、防水シートと固定プレート２は融着される。５．０ＭＰａを超えるような圧力で押えると圧力で防水シート４が薄くなってしまったり破損したりするといった問題や、固定プレート２が変形してしまうといった問題があるので好ましくない。   As shown in FIG. 2, the surface of the fixing plate 2 is covered with a thermoplastic coating material, and is overlapped with the waterproof sheet 4, and is made of metal by the electromagnetic induction heater D from above the waterproof sheet 4. The fixing plate 2 is fused and fixed without opening a hole in the waterproof sheet 4 by heating the plate body 5 and melting the covering material 6 on the surface. After melting the coating material by electromagnetic induction heating, the waterproof sheet is pressed by pressing for 5 to 60 seconds at a pressure of 0.05 to 5.0 MPa, usually 0.05 to 0.5 MPa from above the waterproof sheet. The fixing plate 2 is fused. Pressing with a pressure exceeding 5.0 MPa is not preferable because there is a problem that the waterproof sheet 4 is thinned or damaged by the pressure, or a problem that the fixing plate 2 is deformed.

本発明においてこの圧着は、磁石からなる圧着具７を用いて行う。図３に示すように電磁誘導加熱により被覆材６を融解した状態で防水シート４の上から圧着具７を固定プレート２に磁着させて磁力により圧力をかける。そうすることによって、圧着の際の圧力を一定にすることができるとともに圧着作業に作業者がつく必要がなくなるので、次の加熱作業等、別の作業を並行して行うことができるようになる。また重量を利用したものではないことから圧着具７の移動等も比較的楽に行うことができる。   In the present invention, this crimping is performed using a crimping tool 7 made of a magnet. As shown in FIG. 3, in a state where the covering material 6 is melted by electromagnetic induction heating, the crimping tool 7 is magnetically attached to the fixed plate 2 from above the waterproof sheet 4, and pressure is applied by magnetic force. By doing so, the pressure at the time of crimping can be made constant and the operator does not have to put on the crimping work, so that another work such as the next heating work can be performed in parallel. . Further, since the weight is not used, the movement of the crimping tool 7 can be performed relatively easily.

この圧着具７を用いて磁力により防水シート４を前記のような圧力で固定プレート２へ押し付けようとすると、５〜３０ｋｇの吸着力を有する圧着具を用いる必要がある。逆に３０ｋｇを超える吸着力を有する圧着具を用いると圧着作業の後に圧着具を回収する際に剥すことが困難となるので好ましくない。   If the pressure-sensitive adhesive 7 is used to press the waterproof sheet 4 against the fixed plate 2 with a magnetic force, it is necessary to use a pressure-sensitive adhesive having an adsorption force of 5 to 30 kg. On the other hand, it is not preferable to use a crimping tool having an adsorbing force exceeding 30 kg because it becomes difficult to remove the crimping tool after the crimping operation.

また、圧着具７には必要に応じて防水シート４と接触する側にクッション層８を配置してもよい（図４）。そうすることによって固定プレート２周辺の押え効果を高めることができる。また、図５のように圧着具７の上に水を吸収したスポンジ体や布を冷却層９としておいたり、水槽を配置することで冷却効果をもたせ、加熱による熱を吸収して融着をはやめることも可能である。逆に冬場の作業において圧着が十分に行われる前に温度が下がってしまったり、もともと長い圧着時間を要するような素材の場合には発熱体を取り付けて保温することも可能である。   Moreover, you may arrange | position the cushion layer 8 in the crimping tool 7 in the side which contacts the waterproof sheet 4 as needed (FIG. 4). By doing so, the presser effect around the fixed plate 2 can be enhanced. Further, as shown in FIG. 5, a sponge body or cloth that has absorbed water is placed on the crimping tool 7 as a cooling layer 9, or a water tank is provided to provide a cooling effect, so that heat generated by heating is absorbed and fused. It is also possible to stop. On the other hand, in the case of a material whose temperature is lowered before the crimping is sufficiently performed in the work in winter or originally requires a long crimping time, it is possible to retain the temperature by attaching a heating element.

本発明で用いる防水シート４の素材として用いられるものは、エチレンプロピレンジエンモノマー（ＥＰＤＭ）、イソプレン・イソブチレン共重合体（ＩＩＲ）等の耐候性に優れるゴムや、ポリ塩化ビニル、塩化ビニル−酢酸ビニル共重合体、ポリエチレン、ポリプロピレン等の合成樹脂を挙げることができる。また、これらの防水シート中にポリエステルやポリアミド、ガラス繊維等からなる織布や不織布を補強材として埋設したものでも構わない。   What is used as a material of the waterproof sheet 4 used in the present invention is rubber having excellent weather resistance such as ethylene propylene diene monomer (EPDM), isoprene / isobutylene copolymer (IIR), polyvinyl chloride, vinyl chloride-vinyl acetate. Examples include synthetic resins such as copolymers, polyethylene, and polypropylene. Moreover, what embed | buried as a reinforcing material the woven fabric and nonwoven fabric which consist of polyester, polyamide, glass fiber etc. in these waterproof sheets may be used.

防水シート４の厚みとしては、０．８〜２．５ｍｍ程度の厚みのものが用いられる。１．０ｍｍ未満であると強度的に不足し、２．５ｍｍを超える厚みになると接合部において段差が大きくなり過ぎて外観を損ねたりシート同士接合部の浮きなどの問題が発生したりするので好ましくない。   The thickness of the waterproof sheet 4 is about 0.8 to 2.5 mm. When the thickness is less than 1.0 mm, the strength is insufficient, and when the thickness exceeds 2.5 mm, the step is excessively large at the joint portion, and the appearance is deteriorated or problems such as floating of the joint portion between sheets occur. Absent.

本発明の固定プレート２は電磁誘導加熱によって加熱されるようにステンレス、亜鉛メッキ鋼板、ガルバニウム鋼板などの導体金属から構成されており、径がφ６０〜１００ｍｍ程度の円形または正方形、矩形などのプレート本体６と、その少なくとも防水シート１と接する表面を覆う被覆材６からなっている。   The fixed plate 2 of the present invention is made of a conductive metal such as stainless steel, a galvanized steel plate, or a galvanium steel plate so as to be heated by electromagnetic induction heating. 6 and a covering material 6 covering at least the surface in contact with the waterproof sheet 1.

被覆材６として用いられるものとしては、防水シート４と融着が可能な熱可塑性樹脂であることが必要になり、ポリエチレン、ポリプロピレン、エチレンビニルアセテートなどのオレフィン樹脂やそれらを変成した塩素化ポリエチレン、塩素化ポリプロピレン、マレイン化エチレンビニルアセテートなどの変成オレフィン樹脂、オレフィン系熱可塑性エラストマーなどが挙げられるが、この中でも下流ゴムと融着したときの接着強度が大きいことからポリプロピレン、オレフィン系熱可塑性エラストマー、ポリエチレンを用いることが好ましい。   As the covering material 6, it is necessary to be a thermoplastic resin that can be fused with the waterproof sheet 4, olefin resins such as polyethylene, polypropylene, ethylene vinyl acetate, and chlorinated polyethylene obtained by modifying them. Modified olefin resins such as chlorinated polypropylene and maleated ethylene vinyl acetate, olefinic thermoplastic elastomers, etc. are mentioned. Among them, polypropylene, olefinic thermoplastic elastomer, It is preferable to use polyethylene.

被覆材６の厚みは０．０５〜２．０ｍｍ、より好ましくは０．０５〜１．０ｍｍの範囲とする。被覆材６の厚みをこのような範囲とすることによって、前記のように防水シートの表面に２０〜２００μｍ深さの凹凸パターンを有していたとしても被覆材６の熱可塑性樹脂が加熱して溶融したときに凹凸パターンの凹部にも十分流れ込むことができるので、接着面積が広くなったことになり接着力としては大きなもの得ることができる。   The thickness of the covering material 6 is 0.05 to 2.0 mm, more preferably 0.05 to 1.0 mm. By setting the thickness of the covering material 6 in such a range, even if the surface of the waterproof sheet has a concavo-convex pattern having a depth of 20 to 200 μm as described above, the thermoplastic resin of the covering material 6 is heated. Since it can sufficiently flow into the concave portions of the concave / convex pattern when melted, the adhesive area is widened, and a large adhesive force can be obtained.

被覆材６の厚みが０．０５未満であると加熱して溶融しても防水シートの凹凸パターン内に十分流れ込むことができず接着力が小さくなってしまうことと薄すぎて強度の面で不安があるという問題が挙げられる。２．０ｍｍを超えると通常の加熱状態では、シートとの接触面まで熱が伝わらず表面が溶融しない状態となるので好ましくない。また、厚みが１．０ｍｍを超えた場合には、被覆材６を防水シートの凹凸パターン内に十分流れ込むだけの溶融させるのに要する加熱時間が長くなるので、より好ましくは１．０ｍｍ以下とすることが好ましいといえる。   If the thickness of the covering material 6 is less than 0.05, even if heated and melted, it cannot sufficiently flow into the concave-convex pattern of the waterproof sheet, and the adhesive strength will be reduced, and it is too thin and uneasy in terms of strength. There is a problem that there is. If the thickness exceeds 2.0 mm, the normal heating state is not preferable because heat is not transmitted to the contact surface with the sheet and the surface does not melt. In addition, when the thickness exceeds 1.0 mm, the heating time required to melt the covering material 6 enough to flow into the uneven pattern of the waterproof sheet becomes longer, and more preferably 1.0 mm or less. It can be said that it is preferable.

また、被覆材６を構成する熱可塑性樹脂は加熱して溶融したときに流れやすいものの方が防水シートの凹凸パターン内に流れ込みやすい。そこで本発明では被覆材６を構成する熱可塑性樹脂のメルトフローレート（ＭＦＲ）が０．１〜３０．０ｇ／１０ｍｉｎの範囲、より好ましくは０．２〜１０．０ｇ／１０ｍｉｎのものを用いている。被覆材６のＭＦＲが０．１ｇ／１０ｍｉｎ未満であると加熱時の流れが悪く防水シート表面の凹凸パターン内に流れ込むことができず接着力が小さくなってしまい、３０．０ｇ／１０ｍｉｎを超えると加熱後の圧着によって樹脂が周囲に溢れて樹脂の厚みが薄くなるので好ましくない。   Moreover, the thermoplastic resin constituting the covering material 6 is more likely to flow into the uneven pattern of the waterproof sheet when it is easy to flow when heated and melted. Therefore, in the present invention, the thermoplastic resin constituting the covering material 6 has a melt flow rate (MFR) in the range of 0.1 to 30.0 g / 10 min, more preferably 0.2 to 10.0 g / 10 min. Yes. When the MFR of the covering material 6 is less than 0.1 g / 10 min, the flow during heating is poor and the adhesive sheet cannot flow into the concave-convex pattern on the surface of the waterproof sheet, and the adhesive force is reduced, and when it exceeds 30.0 g / 10 min. Since the resin overflows to the surroundings due to the pressure bonding after heating, the thickness of the resin becomes thin.

また、プレート本体５と被覆材６とは、例えば融着や接着剤を介在するなどして固着されている。プレート本体５は、電磁誘導加熱によって加熱することのできる導体である必要があり、さらには防錆性、耐候性の高いものが好ましく、具体的には鋼板、溶融亜鉛メッキ鋼板、溶融アルミニウムメッキ鋼板、冷間圧延ステンレス鋼板、アルミニウム板、アルミニウム合金板などが挙げられる。   Further, the plate body 5 and the covering material 6 are fixed to each other by, for example, fusing or interposing an adhesive. The plate body 5 needs to be a conductor that can be heated by electromagnetic induction heating, and preferably has a high rust resistance and weather resistance. Specifically, a steel plate, a hot dip galvanized steel plate, a hot dip aluminum plated steel plate. Cold rolled stainless steel plate, aluminum plate, aluminum alloy plate and the like.

このプレート本体５の厚みは使用する金属の種類によっても夫々異なるが、通常０．４〜２．０ｍｍ程度のものが用いられる。０．４ｍｍ未満であると剛性が低く屋根葺材としての形状を保つことができず、防水シート４が風の負圧などで浮き上がろうとした時に破壊される可能性がある。また２．０ｍｍを超えると加工性が乏しくなる上に重量が大きくなり、防水シート４上に現れる段差が大きくなり外観を損ねることになるので好ましくない。特にステンレス鋼を用いる場合は０．５〜１．０ｍｍの厚さがもっとも好ましい。ステンレス鋼であればこの範囲で剛性も十分に得られ、また、金切りはさみで簡単に切断加工することができ、施工時の加工も容易である。   The thickness of the plate body 5 varies depending on the type of metal used, but a thickness of about 0.4 to 2.0 mm is usually used. If it is less than 0.4 mm, the rigidity is low and the shape as the roofing material cannot be maintained, and there is a possibility that the waterproof sheet 4 may be destroyed when it tries to lift up due to negative wind pressure or the like. On the other hand, if it exceeds 2.0 mm, the workability becomes poor, the weight increases, the step appearing on the waterproof sheet 4 becomes large, and the appearance is impaired. In particular, when stainless steel is used, a thickness of 0.5 to 1.0 mm is most preferable. If it is stainless steel, sufficient rigidity can be obtained in this range, and it can be easily cut with a metal cutting scissor, and the processing at the time of construction is also easy.

コンクリート下地などに防水層を形成する防水工法に係り、特に既存の下地状態に左右されることなく防水層を形成することのできる機械的固定工法において利用することができる。   The present invention relates to a waterproofing method for forming a waterproof layer on a concrete base or the like, and can be used in a mechanical fixing method in which a waterproof layer can be formed without being influenced by an existing base state.
