Description

本発明は、防水下地の上に断熱板を敷き詰めて断熱層を形成し、その断熱層の上に防水シートを敷設して防水層を形成してある防水構造に関する。   The present invention relates to a waterproof structure in which a heat insulating layer is formed on a waterproof base to form a heat insulating layer, and a waterproof sheet is formed on the heat insulating layer to form a waterproof layer.

従来、この種の防水構造としては、防水下地の上に並べて配置された発泡樹脂製の複数の断熱板と、前記断熱板の目地での下方から上方への空気の流通を防ぐ密閉テープと、前記各断熱板の上に点在させてネジ部材で前記防水下地にそれぞれ固定された複数の防水シート固定板と、前記各防水シート固定板にわたって配置されて、その下面を前記各防水シート固定板に固定してある防水シートを設けてあるものがあった（例えば、特許文献１参照）。   Conventionally, as this type of waterproof structure, a plurality of foamed resin heat insulating plates arranged side by side on a waterproof base, and a sealing tape for preventing air flow from the bottom to the top at the joint of the heat insulating plate, A plurality of waterproof sheet fixing plates that are interspersed on each of the heat insulating plates and are respectively fixed to the waterproof base with screw members, and the waterproof sheet fixing plates are disposed over the respective waterproof sheet fixing plates, and the lower surfaces thereof are arranged on the respective waterproof sheet fixing plates.

特開２００６−７７５０６号公報（図１，図２）JP 2006-77506 A (FIGS. 1 and 2)

上述した従来の防水構造によれば、例えば、防水シートが損傷すると、防水シート上の水はその損傷部分を通して裏面側に回り、防水下地側への漏水を引き起こす危険性が高い。
即ち、防水性の低い断熱板を使用してある場合には、防水シートの裏面側に廻った水は、断熱板を通して下方の防水下地側へ漏水する。また、防水性を有する断熱板を使用していたとしても、防水シート固定板のネジ部材が断熱板を貫通しているから、ネジ部材周りが漏水経路となって防水下地側への漏水を引き起こす危険性が高い。 According to the conventional waterproof structure described above, for example, when the waterproof sheet is damaged, the water on the waterproof sheet travels to the back side through the damaged portion, and there is a high risk of causing water leakage to the waterproof base.
That is, in the case where a heat-insulating plate having a low waterproof property is used, water that has traveled to the back side of the waterproof sheet leaks to the waterproof base side below through the heat-insulating plate. Moreover, even if a heat-insulating plate having waterproof properties is used, the screw member of the waterproof sheet fixing plate penetrates the heat-insulating plate, so that the periphery of the screw member becomes a water leakage path and causes water leakage to the waterproof base. High risk.

従って、本発明の目的は、上記問題点を解消し、防水シートが損傷しても、水が防水下地側へ漏水しにくい防水構造を提供するところにある。   Accordingly, an object of the present invention is to provide a waterproof structure that solves the above problems and prevents water from leaking to the waterproof base even if the waterproof sheet is damaged.

本発明の第１の特徴構成は、防水下地の上に並べて配置された防水性を有する複数の断熱板と、隣接する前記断熱板どうしの目地の全長にわたって密閉状態に設置された防水テープと、前記各断熱板の上に点在させてネジ部材で前記防水下地にそれぞれ固定された複数の防水シート固定板と、前記各防水シート固定板にわたって配置されて、その下面を前記各防水シート固定板に固定してある防水シートと、前記ネジ部材の周りにおいて前記防水シート固定板と前記断熱板との間に設置され、前記ネジ部材の貫通部分を密閉状態にシールするシール材とを設けてあるところにある。   A first characteristic configuration of the present invention is a plurality of waterproof heat insulating plates arranged side by side on a waterproof base, and a waterproof tape installed in a sealed state over the entire length of joints between the adjacent heat insulating plates, A plurality of waterproof sheet fixing plates that are interspersed on each of the heat insulating plates and are respectively fixed to the waterproof base with screw members, and the waterproof sheet fixing plates are disposed over the respective waterproof sheet fixing plates, and the lower surfaces thereof are arranged on the respective waterproof sheet fixing plates. And a sealing material that is installed between the waterproof sheet fixing plate and the heat insulating plate around the screw member, and seals a through portion of the screw member in a sealed state. By the way.

本発明の第１の特徴構成によれば、防水シートによる第１防水層に加えて、防水性を有する複数の断熱板と、それらの目地全長にわたって密閉状態に設置された防水テープとによる第２防水層が構成され、二重の防水層によって、より確実な防水を実現することができる。
また、断熱板を貫通するネジ部材の設置箇所については、前記ネジ部材の周りにおいて前記防水シート固定板と前記断熱板との間に設置され、前記ネジ部材の貫通部分を密閉状態にシールするシール材とを設けてあるから、ネジ部材の貫通部分に関しても防水性を維持することが可能となる。 According to the 1st characteristic structure of this invention, in addition to the 1st waterproof layer by a waterproof sheet, it is the 2nd by the waterproof tape installed in the sealing state over the several heat insulation board which has waterproofness, and those joint whole length. A waterproof layer is configured, and more reliable waterproofing can be realized by the double waterproof layer.
The screw member that penetrates the heat insulating plate is installed between the waterproof sheet fixing plate and the heat insulating plate around the screw member, and seals sealing the penetrating portion of the screw member in a sealed state. Since the material is provided, it is possible to maintain waterproofness even with respect to the penetrating portion of the screw member.

本発明の第２の特徴構成は、前記シール材は、発泡ゴム体によって構成してあり、前記防水シート固定板と前記断熱板とによって挟圧されているところにある。   According to a second characteristic configuration of the present invention, the sealing material is formed of a foamed rubber body and is sandwiched between the waterproof sheet fixing plate and the heat insulating plate.

本発明の第２の特徴構成によれば、シール材が発泡ゴム体で構成してあるから、中実のシール材に比べてシール材の弾性変形能を高く、シート固定板と断熱板とで挟圧される際、少ない力で、弾性変形させることができる。また弾性変形能が高いことから、挟圧されるシート固定板や断熱板の形状にシール材が馴染みやすく、シール対象の隙間に満遍なく拡がって高いシール効果を発揮することができる。   According to the second characteristic configuration of the present invention, since the sealing material is formed of a foamed rubber body, the elastic deformation capacity of the sealing material is higher than that of the solid sealing material, and the sheet fixing plate and the heat insulating plate When pinched, it can be elastically deformed with a small force. In addition, since the elastic deformability is high, the sealing material can be easily adapted to the shape of the sheet fixing plate and the heat insulating plate to be sandwiched, and can spread evenly in the gaps to be sealed to exhibit a high sealing effect.

本発明の第３の特徴構成は、前記防水下地より立ち上がる建物立上部と前記断熱板との取り合い部には、その取り合い部全長にわたって密閉状態に防水テープを設置してあるところにある。   A third characteristic configuration of the present invention is that a waterproof tape is installed in a sealed state over the entire length of the joint portion at the joint portion of the building standing up from the waterproof base and the heat insulating plate.

本発明の第３の特徴構成によれば、断熱板と防水テープとによる第２防水層の縁部を、防水テープによって建物立上部と密閉状態に連結することで、より完璧な第２防水層を形成することができ、前記防水シートによる第１防水層と合わせた二重防水層の信頼性を、更に向上させることができる。   According to the third characteristic configuration of the present invention, the edge of the second waterproof layer formed of the heat insulating plate and the waterproof tape is connected to the building upper portion with the waterproof tape in a hermetically sealed state, thereby providing a more perfect second waterproof layer. The reliability of the double waterproof layer combined with the first waterproof layer by the waterproof sheet can be further improved.

前記防水シート３は、防水性を有する合成樹脂製シート（例えば、軟質塩化ビニル）によって構成してあり、敷設された前記断熱板２上に点在させて設置した防水シート固定板５を使用して固定される。尚、建物外周部でコンクリートスラブ１より立ち上がる建物立上部７においては、その建物立上部７に沿って防水シート３も立ち上げられて、コーキング処理等の端部防水処理を施される。
この防水シート３の一連によって、第１防水層Ｐ１が構成される。 The waterproof sheet 3 is made of a waterproof synthetic resin sheet (for example, soft vinyl chloride), and uses waterproof sheet fixing plates 5 that are scattered and installed on the heat insulating plate 2 that is laid. Fixed. In addition, in the building upright part 7 which rises from the concrete slab 1 at the outer periphery of the building, the waterproof sheet 3 is also raised along the building upright part 7 and subjected to end waterproofing such as coking treatment.
The first waterproof layer P1 is constituted by a series of the waterproof sheets 3.

前記防水テープＭは、防水性を有する合成樹脂製テープで構成してあり、前記断熱板２どうしの目地において両断熱板２にわたる状態で目地全長に貼着してあることで、目地の防水を図っている。具体的な構成の一例は、樹脂繊維の不織布層の表面に金属ラミネート層を一体に設け、裏面に接着層を備えたものが挙げられる。
尚、建物外周部の前記建物立上部７においては、建物立上部７と断熱板２との取り合い部全長にわたって、この防水テープＭを貼着して取り合い部の防水を図ってある。
従って、防水テープＭと断熱板２との一連によって、第２防水層Ｐ２が構成され、前記第１防水層Ｐ１とこの第２防水層Ｐ２とによって構成される二重防水層によって、より確実な防水構造を形作っている。 The waterproof tape M is made of a waterproof synthetic resin tape, and is bonded to the entire length of the joint in a state that spans both the heat insulating plates 2 at the joints between the heat insulating plates 2, thereby waterproofing the joints. I am trying. An example of a specific configuration is one in which a metal laminate layer is integrally provided on the surface of a nonwoven fabric layer of resin fibers and an adhesive layer is provided on the back surface.
In addition, in the said building upright part 7 of a building outer peripheral part, this waterproofing tape M is affixed over the full length of the joint part of the building upright part 7 and the heat insulation board 2, and the joint part is waterproofed.
Therefore, the second waterproof layer P2 is constituted by a series of the waterproof tape M and the heat insulating plate 2, and the double waterproof layer constituted by the first waterproof layer P1 and the second waterproof layer P2 is more reliable. Forms a waterproof structure.

前記防水シート固定板５は、図１、図２に示すように、円板形状に形成してあり、薄い金属板を凹凸のある断面形状にプレス成形することで、軽量でありながら強度の高いものに構成されている。また、防水シート固定板５の中央部には、ネジ部材４を挿通するネジ挿通孔５ａが形成してあり、その周りには、ネジ部材４の拡径頭部４ａが納まる座繰り部５ｂが形成してある。従って、防水シート固定板５をネジ部材４でコンクリートスラブ１に固定した状態では、拡径頭部４ａが防水シート固定板５の上面より上方へ突出しないように構成されている。
また、防水シート固定板５の上面には、ホットメルト接着剤層５ｃを一体的に設けてあり、コンクリートスラブ１に固定した防水シート固定板５の上から防水シート２を被せた後、防水シート２越しに電磁誘導加熱装置を使用して防水シート固定板５を加熱し、その熱によって前記ホットメルト接着剤層５ｃを溶かして防水シート固定板５に防水シート２を接着することができる。
尚、建物立上部７と断熱板２との取り合い部に設置される防止シート固定板５は、薄い帯板を幅方向中間部で屈曲させた断面「Ｌ字」状に形成したもの（又は、帯板状のもの）を使用する（図１、図３参照）。 As shown in FIGS. 1 and 2, the waterproof sheet fixing plate 5 is formed in a disc shape, and is light in weight but high in strength by press-molding a thin metal plate into an uneven cross-sectional shape. It is made up of things. In addition, a screw insertion hole 5a through which the screw member 4 is inserted is formed in the central portion of the waterproof sheet fixing plate 5, and a countersink portion 5b in which the enlarged diameter head 4a of the screw member 4 is accommodated is formed around the screw insertion hole 5a. It is formed. Therefore, in the state where the waterproof sheet fixing plate 5 is fixed to the concrete slab 1 with the screw member 4, the enlarged-diameter head 4 a is configured not to protrude upward from the upper surface of the waterproof sheet fixing plate 5.
Further, a hot melt adhesive layer 5c is integrally provided on the upper surface of the waterproof sheet fixing plate 5, and after the waterproof sheet 2 is put on the waterproof sheet fixing plate 5 fixed to the concrete slab 1, the waterproof sheet is provided. 2, the waterproof sheet fixing plate 5 is heated using an electromagnetic induction heating device, and the hot melt adhesive layer 5 c is melted by the heat to bond the waterproof sheet 2 to the waterproof sheet fixing plate 5.
In addition, the prevention sheet fixing plate 5 installed in the joint portion between the building upright portion 7 and the heat insulating plate 2 is formed in a cross-sectional “L-shape” in which a thin strip is bent at an intermediate portion in the width direction (or A strip-like one) is used (see FIGS. 1 and 3).

前記シール材６は、発泡ゴム体（例えば、ＥＰＤＭゴムの発泡体）によって構成してあり、前記防水シート固定板５より小径の円板形状に成形してある。
中央部には、前記ネジ部材４を挿通自在なネジ挿通孔６ａが設けられている。
前記防水シート固定板５をコンクリートスラブ１に固定する際に、両ネジ挿通孔５ａ，６ａが合致するように防水シート固定板５の裏面に沿わせてシール材６を配置する。ネジ部材４を両ネジ挿通孔５ａ，６ａに挿通させて断熱板２を貫通させてコンクリートスラブ１に螺着させると、シール材６は、ネジ部材４の周りにおいて前記防水シート固定板５と前記断熱板２とによって挟圧され弾性変形しながらネジ部材４周りの空間を埋め、前記ネジ部材４の貫通部分を密閉状態にシールすることができる。
従って、前記第２防水層は、ネジ部材４が貫通するものの、その貫通部分を前記シール材６によって密閉しているから、第２防水層としての防水性能を維持することができる（図２参照）。
尚、建物立上部７と断熱板２との取り合い部に設置されるＬ字状の防水シート固定板５に対応するシール材６は、その防水シート固定板５の底面と同形のものを使用する。 The sealing material 6 is made of a foam rubber body (for example, a foam of EPDM rubber), and is formed into a disk shape having a smaller diameter than the waterproof sheet fixing plate 5.
A screw insertion hole 6a through which the screw member 4 can be inserted is provided at the center.
When the waterproof sheet fixing plate 5 is fixed to the concrete slab 1, the sealing material 6 is disposed along the back surface of the waterproof sheet fixing plate 5 so that both screw insertion holes 5a and 6a are matched. When the screw member 4 is inserted into the both screw insertion holes 5a and 6a and penetrates the heat insulating plate 2 and screwed to the concrete slab 1, the sealing material 6 is placed around the screw member 4 with the waterproof sheet fixing plate 5 and the The space around the screw member 4 can be filled while being pinched by the heat insulating plate 2 and elastically deformed, and the through portion of the screw member 4 can be sealed in a sealed state.
Therefore, although the screw member 4 penetrates the second waterproof layer, the penetrating portion is sealed by the sealing material 6, and thus the waterproof performance as the second waterproof layer can be maintained (see FIG. 2). ).
In addition, the sealing material 6 corresponding to the L-shaped waterproof sheet fixing plate 5 installed at the joint portion between the building upright portion 7 and the heat insulating plate 2 uses the same shape as the bottom surface of the waterproof sheet fixing plate 5. .

By bonding 2, the first waterproof layer P <b> 1 is formed.

本実施形態の防水構造によれば、防水シートによる第１防水層と、断熱板と防水テープとによる第２防水層との二重の防水層によって、より確実な防水を実現することができる。また、弾性変形能の高い発泡ゴム体によるシール材をネジ部材の周りに設置することで、高いシール効果を発揮して、ネジ部材の貫通部分の防水性をも維持することが可能となる。   According to the waterproof structure of the present embodiment, more reliable waterproofing can be realized by the double waterproof layer of the first waterproof layer made of the waterproof sheet and the second waterproof layer made of the heat insulating plate and the waterproof tape.
