従来、建築物の屋上、床、駐車場等の新規若しくは既設の部位における防水には、防水シートによる防水、樹脂を塗布して防水層を形成させる樹脂防水、樹脂と繊維強化材とを複合化させたＦＲＰ防水などの施工方法が採用されてきた。
このような防水施工に際しては、充分に乾燥した下地に施工が施されないと下地の水分の蒸気圧或いは空気膨張などにより防水層にフクレが生じて剥離する、漏水する等の原因となる、美観を損ねる等の問題が発生する。しかしながら施工期間を短縮した施工法が求められていた。
また、既設の樹脂防水床、ＦＲＰ床などの補修施工にあっては、既設床の取り剥がしには多大な工数、時間を要するために実質不可能な状況にあり、既設の床をそのままの状態で施工できる施工法が求められていた。
Conventionally, for waterproofing in new or existing parts such as building rooftops, floors, parking lots, etc., waterproofing with waterproof sheets, resin waterproofing that forms a waterproof layer by applying resin, resin and fiber reinforcement are combined Construction methods such as FRP waterproofing have been adopted.
In such waterproofing construction, if the construction is not applied to a sufficiently dry base, the waterproof layer will swell due to vapor pressure or air expansion of the base, causing peeling, leaking, etc. Problems such as damage occur. However, there has been a demand for a construction method that shortens the construction period.
In addition, when repairing existing resin waterproof floors, FRP floors, etc., it takes a lot of man-hours and time to remove existing floors. There was a need for a construction method that could be used for construction.
解決しようとする問題点は、防水施工において、下地施工が不十分だと、フクレ、剥離、漏水の原因となり、また、既設の床をそのまま施工できないことであった。 The problem to be solved is that if the foundation construction is insufficient in waterproof construction, it causes blistering, peeling, and water leakage, and the existing floor cannot be constructed as it is.

The resin layer is not damaged and has excellent durability.
請求項3の発明は、基体上に通気性シート体を配置し、この通気性シート体の一部表面に不飽和ポリエステル樹脂繊維強化樹脂層を形成し、この不飽和ポリエステル樹脂繊維強化樹脂層の上から固定具を基体に打ち込んだのち、少なくとも先に不飽和ポリエステル樹脂繊維強化樹脂層の施工されなかった通気性シート体の表面並びに固定具の上に、不飽和ポリエステル樹脂繊維強化樹脂層を形成することを特徴とする防水仕上げ構造を有する防水仕上げ方法で、フクレ、剥離、漏水がなく、また、既設の床をそのまま施工できる仕上げ方法で耐久性に優れる。 According to the invention of claim 3, an air permeable sheet body is disposed on a substrate, an unsaturated polyester resin fiber reinforced resin layer is formed on a part of the surface of the air permeable sheet body, and the unsaturated polyester resin fiber reinforced resin layer is formed.

The invention according to
従来、下地の含水率が高いために施工できない、既設床を取り剥がさないと施工できないなどの問題があるため、極めて限られた物件しか施工できなかたが、本発明になる防水仕上げ方法は、下地から揮発する水蒸気が通気性シート体を通じて外部に放出されるため、下地の含水率が高くても施工できる効果がある。また、既設の樹脂防水などの下地を取り剥がさなくてもその上に施工できるため、施工物件、施工条件に制約されることなく直ちに施工できる。
また、本発明の防水仕上げ構造は、通気性シート体を介して不飽和ポリエステル樹脂繊維強化樹脂層が設けられ、しかも限定された適所において打ち込まれた固定具により基体と不飽和ポリエステル樹脂繊維強化樹脂層とが通気性シート体を介して接続された構造であるために、防水層と基体とが緩やかに固定されており、不飽和ポリエステル樹脂繊維強化樹脂層と基体との間に寸法変化の差が生じても両者の間に応力が生じることがなく、防水仕上げ構造に損傷に至らず剥離などが発生しない。特に不飽和ポリエステル樹脂繊維強化樹脂層に設けた孔が固定具の軸径よりも大きく設定され、両者の間の空隙に弾性シーリング材などを充填した施工がなされた場合には、不飽和ポリエステル樹脂繊維強化樹脂層と下地とが緩やかに接続される構造に仕上げられるため、不飽和ポリエステル樹脂繊維強化樹脂層と基体とが接続されている故に生じる応力が大幅に緩衝され、長期間の使用に耐えられる防水構造となる。
なお、孔の設けられた通気性シート体が使用された場合には、孔を通じて不飽和ポリエステル樹脂繊維強化樹脂層の施工に使用される樹脂が基体表面にまで連通するため、固定具の固定と併せて樹脂による固定効果が得られる。
Conventionally, because there is a problem that it can not be constructed because the moisture content of the foundation is high, or it can not be constructed unless the existing floor is removed, the waterproof finishing method according to the present invention is the foundation. Since the water vapor that volatilizes is released to the outside through the breathable sheet body, there is an effect that the construction can be performed even if the moisture content of the base is high. Moreover, since it can construct on the existing resin waterproofing etc. without removing the foundation, it can be constructed immediately without being restricted by construction properties and construction conditions.
Further, the waterproof finish structure of the present invention is provided with an unsaturated polyester resin fiber reinforced resin layer provided with a breathable sheet body, and by a fixing tool driven in a limited place, the base and the unsaturated polyester resin fiber reinforced resin. The waterproof layer and the base are loosely fixed because the layer is connected via the breathable sheet body, and there is a difference in dimensional change between the unsaturated polyester resin fiber reinforced resin layer and the base. Even if this occurs, no stress is generated between them, and the waterproof finish structure is not damaged and peeling does not occur. In particular, when the hole provided in the unsaturated polyester resin fiber reinforced resin layer is set larger than the shaft diameter of the fixture and the gap between them is filled with an elastic sealing material, etc., the unsaturated polyester resin Since the fiber reinforced resin layer and the groundwork are gently connected, the stress generated due to the connection between the unsaturated polyester resin fiber reinforced resin layer and the substrate is greatly buffered to withstand long-term use. Waterproof structure.
When a breathable sheet body with holes is used, the resin used for the construction of the unsaturated polyester resin fiber reinforced resin layer communicates with the substrate surface through the holes. In addition, the fixing effect by the resin is obtained.
本発明は、このような状況に鑑みて検討、開発されたものであり、下地の状態が従来の施工法では必ずしも適当ではない状態であっても防水施工できる防水仕上げ方法と防水仕上げ構造を提供せんとするものであり、以下詳細に説明する。 The present invention has been studied and developed in view of such a situation, and provides a waterproof finishing method and a waterproof finishing structure that can be waterproofed even when the state of the ground is not always appropriate in the conventional construction method. This will be described in detail below.
本発明の防水仕上げ構造は前記のように、新規床、既設床などの基体上に通気性シート体を配置し、その上に部分的に不飽和ポリエステル樹脂繊維強化樹脂層を仕上げたのち、該不飽和ポリエステル樹脂繊維強化樹脂層の上から該基体に固定具を打ち込み、次いで少なくとも固定具の上に不飽和ポリエステル樹脂繊維強化樹脂層を施工して仕上げる、或いは床などの基体上に通気性シート体を配置し、その全面上に不飽和ポリエステル樹脂繊維強化樹脂層を施工したのち、該不飽和ポリエステル樹脂繊維強化樹脂層から該基体に固定具を打ち込み、次いで少なくとも該固定具の上に不飽和ポリエステル樹脂繊維強化樹脂層を施工して仕上げられる。 The waterproof finish structure of the present invention, as described above, arranges a breathable sheet on a substrate such as a new floor or an existing floor, and partially finishes an unsaturated polyester resin fiber reinforced resin layer thereon, A fixture is driven into the substrate from above the unsaturated polyester resin fiber reinforced resin layer, and then at least the unsaturated polyester resin fiber reinforced resin layer is applied to the fixture and finished, or a breathable sheet on a substrate such as a floor After placing the body and constructing an unsaturated polyester resin fiber reinforced resin layer on the entire surface, a fixture is driven from the unsaturated polyester resin fiber reinforced resin layer onto the substrate, and then at least on the fixture Finished with a polyester resin fiber reinforced resin layer.
本発明になる防水仕上げ方法は前記のように新設の床、屋上、駐車場、既設の床、駐車場、屋上などに適用できるものであつて、基体の材質についてもモルタル、コンクリート、発泡コンクリート、鉄製プレート、石製の板体、木製板体、樹脂防水床、などあらゆる素材からなるものについて施工できるが、中でも基体の含水率が問題になるモルタル、コンクリート、発泡コンクリートなどの基体に対して、基体の含水率が高くても施工できる点、老朽化した既設の樹脂防水床などの上に施工できる点で好都合であり、どのような施工条件においても問題なく施工実施できるようにしたものである。 The waterproof finishing method according to the present invention is applicable to new floors, rooftops, parking lots, existing floors, parking lots, rooftops, etc. as described above, and the base material is also mortar, concrete, foamed concrete, Although it can be constructed for all materials such as iron plate, stone plate, wooden plate, resin waterproof floor, etc., especially for substrates such as mortar, concrete, foamed concrete, etc. where the moisture content of the substrate is a problem It is advantageous in that it can be constructed even when the moisture content of the substrate is high, and it can be constructed on an old resin waterproof floor that has deteriorated, and can be constructed without any problems under any construction conditions. .
本発明に係わる通気性シート体は通気性を持つ材質若しくは構造からなるものであれば、特に限定されるものではないが、その１例としてポリエステル、ナイロン、ビニロン、アクリルなどの合成繊維、或いはこれらの混合された複合繊維、ガラス繊維などの無機繊維、麻繊維など天然繊維、合成繊維に無機繊維、天然繊維などが混合された複合繊維から加工された不織布、織布など基材の片面若しくは両面に薄い非通気性層が積層されたもの、或いは該非通気性層の両面に該基材が積層されたものなどが使用される。このような通気性シート体では、該通気性層の基材は、好ましくは０．５〜２ｍｍの厚みのあるものが好ましい。０．５ｍｍ以下では経時的に厚みがうすくなってしまい通気性がなくなる場合が予想され好ましくない。
また、通気性シート体には適所に円形、方形などの各種の形状の孔が設けられたものであれば、不飽和ポリエステル樹脂繊維強化樹脂層の施工に使用された樹脂が該孔を通して基体表面にまで連続した状態で硬化して不飽和ポリエステル樹脂繊維強化樹脂層が形成されるため、固定具による接合と併せて基体との接合を確保することができ、固定具の打設個数を少なくできる。
The breathable sheet according to the present invention is not particularly limited as long as it is made of a breathable material or structure, but examples thereof include synthetic fibers such as polyester, nylon, vinylon, and acrylic, or these One side or both sides of a base material such as a composite fiber, a fiber such as a glass fiber, a natural fiber such as a hemp fiber, a nonwoven fabric processed from a composite fiber in which a synthetic fiber is mixed with an inorganic fiber, a natural fiber, etc. A thin air-permeable layer is laminated, or a material in which the base material is laminated on both surfaces of the air-impermeable layer. In such a breathable sheet body, the base material of the breathable layer preferably has a thickness of 0.5 to 2 mm. If the thickness is 0.5 mm or less, the thickness becomes thin with time and the air permeability may be lost.
In addition, if the breathable sheet body has holes of various shapes such as a circle and a rectangle in place, the resin used for the construction of the unsaturated polyester resin fiber reinforced resin layer passes through the holes to the surface of the substrate. Since the unsaturated polyester resin fiber reinforced resin layer is formed by curing in a continuous state, it is possible to ensure the bonding with the base body together with the bonding with the fixing tool, and to reduce the number of fixing tools to be placed. .
該非通気性層には樹脂シート、例えばポリエチレン樹脂、ポリプロピレン樹脂、塩化ビニル樹脂などの合成樹脂シート、或いはアスファルトシート等の厚み０．１〜１．０ｍｍ程度の非通気性の素材が使用される。 For the non-breathable layer, a non-breathable material having a thickness of about 0.1 to 1.0 mm such as a resin sheet, for example, a synthetic resin sheet such as polyethylene resin, polypropylene resin, or vinyl chloride resin, or an asphalt sheet is used.
非通気性層が片面のみに積層された通気性シート体の場合は該非通気性層を上に向けて配置することが望ましい。非通気性層を上に位置させることにより、その上に施工する不飽和ポリエステル樹脂を該通気性シート体の内部にまで浸透を防止して通気性が損なわれることを防止できる。 In the case of a breathable sheet body in which the non-breathable layer is laminated only on one side, it is desirable to arrange the non-breathable layer facing up. By disposing the non-breathable layer on the upper side, it is possible to prevent the unsaturated polyester resin applied on the non-breathable layer from penetrating into the breathable sheet body and thereby impairing the breathability.
その他の通気性シート体の例として、例えば各種ゴムシート、アスファルトシート、プラスチックシートなどからなる厚み１〜５ｍｍのシートの表面に、平面形状が格子状、６角形状などであつて、平面形状が相互に連接した溝の設けられた通気性シート体なども、溝のある面を基体側に接触させ溝を連通した通気部として活用できる通気性シート体として利用できる。 Examples of other breathable sheet bodies include, for example, a surface of a sheet having a thickness of 1 to 5 mm made of various rubber sheets, asphalt sheets, plastic sheets, etc., and the planar shape is a lattice shape, a hexagonal shape, etc. A breathable sheet body provided with grooves connected to each other can also be used as a breathable sheet body that can be used as a ventilation section in which the grooved surface is brought into contact with the base surface side.
基体と通気性シート体とは単に配置されるか、接着剤で接着して固定されてもよい。
また、直接、基体との接着が難しい場合は基体表面にウレタン樹脂系、エボキシ樹脂系などの樹脂系プライマーを塗布したのち接着剤で接着されてもよい。
The substrate and the air-permeable sheet body may be simply arranged or may be fixed by bonding with an adhesive.
Further, when it is difficult to directly adhere to the substrate, a resin primer such as urethane resin or epoxy resin may be applied to the surface of the substrate and then adhered with an adhesive.
通気性シート体の表面の一部若しくは全面に不飽和ポリエステル樹脂繊維強化樹脂層が設けられる。該不飽和ポリエステル樹脂繊維強化樹脂層の形成は、該通気性シート体の基材に積層された非通気性層の表面に強化繊維シート、例えばガラス繊維マットを配置した上に硬化剤の配合された不飽和ポリエステル樹脂を塗布し、更に強化繊維シートを重ねるか、該通気性シート体の表面の非通気性層上に不飽和ポリエステル樹脂を塗布したのち、塗布面に強化繊維シートを重ね、更に不飽和ポリエステル樹脂を塗布するなどして、強化繊維シートに不飽和ポリエステル樹脂を浸透させた状態で硬化させて不飽和ポリエステル樹脂繊維強化樹脂層を形成させることにより得られる。 An unsaturated polyester resin fiber reinforced resin layer is provided on a part or the entire surface of the breathable sheet body. The unsaturated polyester resin fiber reinforced resin layer is formed by blending a reinforcing fiber sheet, such as a glass fiber mat, on the surface of the non-breathable layer laminated on the base material of the breathable sheet body, and then adding a curing agent. After applying the unsaturated polyester resin, and further stacking the reinforcing fiber sheet, or after applying the unsaturated polyester resin on the non-breathable layer on the surface of the breathable sheet body, the reinforcing fiber sheet is stacked on the coated surface. It is obtained by applying an unsaturated polyester resin or the like to cure the unsaturated fiber in a state where the unsaturated polyester resin is infiltrated into the reinforcing fiber sheet to form an unsaturated polyester resin fiber reinforced resin layer.
更に、このように形成された不飽和ポリエステル樹脂繊維強化樹脂層の適所に孔を設け、該孔を通して固定具を基体まで打ち込んで、該不飽和ポリエステル樹脂繊維強化樹脂層と該通気性シート体とを該下地に固定させる。孔のサイズは固定具の軸径よりも大きいサイズとして固定具を遊嵌状態で基体に打ち込むことが望ましい。孔径と固定具の軸径が同一であるか若しくは小さいと固定具を打ち込む際に不飽和ポリエステル樹脂繊維強化樹脂層を傷める、不飽和ポリエステル樹脂繊維強化樹脂層の収縮・膨張すると応力が固定具に及んで固定具が壊れる、不飽和ポリエステル樹脂繊維強化樹脂層が破損するなどの問題が発生するため好ましくない。 Furthermore, a hole is provided at an appropriate position of the thus formed unsaturated polyester resin fiber reinforced resin layer, and a fixing tool is driven to the base through the hole, and the unsaturated polyester resin fiber reinforced resin layer, the breathable sheet body, Is fixed to the substrate. It is desirable that the size of the hole is larger than the shaft diameter of the fixture, and the fixture is driven into the base body in a loosely fitted state. If the hole diameter and the shaft diameter of the fixture are the same or small, the unsaturated polyester resin fiber reinforced resin layer will be damaged when the fixture is driven, and stress will be applied to the fixture when the unsaturated polyester resin fiber reinforced resin layer contracts or expands. This is not preferable because problems such as breakage of the fixing tool and breakage of the unsaturated polyester resin fiber reinforced resin layer occur.
このように孔と固定具の軸との間に設けられた空隙には弾性シーリング材、例えば弾性のある材質からなるシリコンシーリング材、ポリサルファイドシーリング材、ウレタン樹脂シーリング材などを注入して充填させることにより固定具と不飽和ポリエステル樹脂繊維強化樹脂層とは緩やかに固定され、温度変化などにより不飽和ポリエステル樹脂繊維強化樹脂層が収縮・膨張しても応力が固定具に直接波及せず、不飽和ポリエステル樹脂繊維強化樹脂層の収縮・膨張の応力により固定具が外れたり、破損することがなくなり、耐久性に優れた防水仕上げ構造が得られる。 In this way, an elastic sealing material, for example, a silicon sealing material made of an elastic material, a polysulfide sealing material, a urethane resin sealing material, or the like, is injected and filled into the gap provided between the hole and the shaft of the fixture. The fixture and the unsaturated polyester resin fiber reinforced resin layer are gently fixed, and even if the unsaturated polyester resin fiber reinforced resin layer contracts or expands due to temperature change, the stress does not directly affect the fixture, and is unsaturated. The fixture is not detached or damaged due to the shrinkage / expansion stress of the polyester resin fiber reinforced resin layer, and a waterproof finish structure with excellent durability can be obtained.
該固定具には、エアーガン或いは金槌で下地まで打ち込む打ち込み式固定金具、或いは下孔を設けておき開脚プラグと一体として使用されるビスを固定する固定金具などが使用される。該固定具の材質は鉄、ステンレス、アルミ等の金属製のもののほか、プラスチック製のものであっても使用できる。
また、孔の設けられた通気性シート体を使用した場合には、通気性シート体の上に形成られることから、固定具の数を少なくすることができる。
As the fixing tool, a driving-type fixing bracket that is driven to the ground with an air gun or a hammer, or a fixing bracket that is provided with a lower hole and fixes a screw that is used integrally with an open leg plug, or the like is used. The fixture can be made of metal such as iron, stainless steel, aluminum, or plastic.
Moreover, when the air permeable sheet body provided with holes is used, it is formed on the air permeable sheet body, so that the number of fixtures can be reduced.
該通気性シート体の表面の一部に不飽和ポリエステル樹脂繊維強化樹脂層を設け、該不飽和ポリエステル樹脂繊維強化樹脂層の上から基体に固定具を打ち込んで固定した場合は、固定具、該不飽和ポリエステル樹脂繊維強化樹脂層並びに該通気性シート体を覆う状態で、不飽和ポリエステル樹脂繊維強化樹脂層を形成させることにより防水仕上げ構造が得られる。
また該通気性シート体の全面に不飽和ポリエステル樹脂繊維強化樹脂層を設け、固定具を該不飽和ポリエステル樹脂繊維強化樹脂層の上から基体に打ち込んで固定する施工法を採用する場合は、少なくとも該固定具の上部を更に不飽和ポリエステル樹脂繊維強化樹脂層を設けることにより防水仕上げ構造が得られる。
なお、表面の仕上がり外観を向上させたり、耐候性能を向上するためにアクリル樹脂系塗料、アクリル・シリコン樹脂系塗料、アクリル・ウレタン樹脂系塗料、不飽和ポリエステル樹脂系塗料などのトップコートが塗布されてもよい。
When an unsaturated polyester resin fiber reinforced resin layer is provided on a part of the surface of the breathable sheet body, and a fixing tool is driven into the base from above the unsaturated polyester resin fiber reinforced resin layer and fixed, A waterproof finish structure is obtained by forming the unsaturated polyester resin fiber reinforced resin layer in a state of covering the unsaturated polyester resin fiber reinforced resin layer and the breathable sheet body.
In addition, when an unsaturated polyester resin fiber reinforced resin layer is provided on the entire surface of the breathable sheet body, and a fixing method is adopted by driving into the substrate from above the unsaturated polyester resin fiber reinforced resin layer and fixing, at least A waterproof finish structure can be obtained by further providing an unsaturated polyester resin fiber reinforced resin layer on the upper part of the fixture.
Top coats such as acrylic resin-based paints, acrylic / silicone resin-based paints, acrylic / urethane resin-based paints, and unsaturated polyester resin-based paints are applied to improve the surface finish and weather resistance. May be.

実施例１に使用したと同一の床にウレタン樹脂プライマー（アイカ工業（株）、商品名ジョリエース ＪＵ−１２７０）を０．２ｋｇ／ｍ２塗布し、乾燥させたのち、硬化剤を配合した不飽和ポリエステル樹脂（アイカ工業（株）、商品名ジョリエースＪＥ−２０００）を０．５ｋｇ／ｍ２塗布し、直ちに坪量４５０ｇ／ｍ２のガラス繊維マットを貼り付ける。更に硬化剤を配合した不飽和ポリエステル樹脂（アイカ工業（株）、商品名ジョリエースＪＥ−２０００）を１．０ｋｇ／ｍ２塗布して防水層とした。次いでトップコートとして硬化剤を配合した不飽和ポリエステル樹脂（アイカ工業（株）、商品名ジョリエースＪＥ−２０８０）を０．４ｋｇ／ｍ２塗布した。
施工後１年経過後において防水層の浮きが発生し、下地と不飽和ポリエステル樹脂繊維強化樹脂層との間に水が溜まっているのが認められた。
Comparative Example 2
The same floor used in Example 1 was coated with 0.2 kg / m 2 of urethane resin primer (Aika Kogyo Co., Ltd., trade name Joliase JU-1270), dried, and then mixed with a curing agent. A saturated polyester resin (Aika Industry Co., Ltd., trade name Jolie's JE-2000) is applied at 0.5 kg / m 2 , and a glass fiber mat having a basis weight of 450 g / m 2 is immediately applied. Furthermore, 1.0 kg / m 2 of an unsaturated polyester resin (Aika Kogyo Co., Ltd., trade name Joliase JE-2000) blended with a curing agent was applied to form a waterproof layer. Next, 0.4 kg / m 2 of an unsaturated polyester resin (Aika Kogyo Co., Ltd., trade name Joliase JE-2080) containing a curing agent as a top coat was applied.
One year after the construction, the waterproof layer was lifted, and water was found to be accumulated between the base and the unsaturated polyester resin fiber reinforced resin layer.
