Description

【０００１】
【発明の属する技術分野】
本発明は、防水下地上に固定された防水シート固定金具の上面に接着材で防水シートを固定して形成してある防水層を改修する防水層改修方法、及び、防水下地上に固定された防水シート固定金具の上に防水層を固定してある防水構造に関する。
【０００２】
【従来の技術】
従来、この種の防水層改修方法としては、図７に示すように、既にある防水層Ｐ１は、そのままの状態で残しておき、その上に新たな防水シート固定金具３を配置すると共に、既にある防水シート４を貫通する状態にビスＢを打ち込んで防水下地２に防水シート固定金具３を固定し、その防水シート固定金具３の上面に接着材で新しい防水シート９を固定して防水層を改修する方法を採っていた。
また、従来の防水構造の内、防水層の改修を実施した場合の防水構造としては、上述のとおり、防水下地２側に位置する防水シート４を貫通させて防水シート固定金具３をビス固定してあり、その防水シート固定金具３の上に新しい防水シート９を接着してあるものがある。
また、従来の防水構造の内、防水層を新設する場合の防水構造としては、図８に示すように、防水下地２上に防水シート固定金具３が固定してあり、その上面に防水シート９を接着固定した一層の防水構造であった。
【０００３】
【発明が解決しようとする課題】
上述した従来の防水層改修方法によれば、新たに防水シート固定金具を防水下地に固定する際に、ビス（他に、例えば、ホールインアンカーや、コンクリート釘等を使用することもある）を使用して実施するわけであるが、ビスの設置に伴っては、ドリル等で防水下地に穴を開ける（ホールインアンカーやコンクリート釘を使用する場合は、ハンマーで強く打ち込んだりする）必要があり、その際、騒音が発生する問題点がある。即ち、建物を使用しながら防水層を改修するような場合、前記騒音は、下階の人に不快感を与えやすい。
そして、新たに防水シート固定金具やビス等の固定材料が必要となるから、設置手間や、使用材料を考慮すると、防水層改修コストの増大を招き易い問題点がある。
【０００４】
また、上述した従来の防水構造の内、防水層の改修を実施した場合の防水構造によれば、防水下地側に位置する防水シートは、前記ビスの貫通によって穴が空いているから、この防水シートには防水効果を期待することができず、防水層全体とした防水効果は、前記新しい防水シートのみに委ねられることとなる。従って、万が一、新しい防水シートに穴があいたら、防水層全体とした防水効果がなくなり、防水上の安全率を高く望みにくい問題点がある。
また、上述した従来の防水構造の内、防水層を新設する場合の防水構造によれば、防水下地上に固定した防水シート固定金具の上面に防水シートを接着固定した一層の防水構造であるから、万が一、防水シートに穴があいたら防水効果がなくなり、上述の改修を実施した場合の防水構造よりも更に防水上の安全率を高く望みにくい問題点がある。
【０００５】
従って、本発明の目的は、上記問題点を解消し、大きな騒音を発せずに防水層改修工事を実施することができる防水層改修方法を提供すると共に、防水上の安全率を確保し易い防水構造を提供するところにある。
【０００６】
【課題を解決するための手段】
請求項１の発明の特徴手段は、図１・５に例示するごとく、防水下地２上に固定された防水シート固定金具３の上面に接着材で防水シート４を固定して形成してある防水層Ｐ１を改修する防水層改修方法において、前記防水シート固定金具への前記防水シート４の固定部の上に、電磁加熱によって発熱する発熱部８ａを備えたホットメルト接着用シート８を前記防水シートに穴を開けない状態に配置し、その上に改修用の改修防水シート９を敷設し、改修防水シート９の上方から電磁加熱によって前記発熱部８ａを加熱することによって、前記ホットメルト接着用シート８を融かして前記改修防水シート９を前記防水シート４上に接着して新防水層Ｐ２を形成するところにある。
【０００７】
請求項１の発明の特徴手段によれば、前記防水シートの上に、電磁加熱によって発熱する発熱部を備えたホットメルト接着用シートを配置し、その上に改修用の改修防水シートを敷設し、改修防水シートの上方から電磁加熱によって前記発熱部を加熱することによって、前記ホットメルト接着用シートを融かして前記改修防水シートを前記防水シート上に接着して新防水層を形成するから、新たに防水シート固定金具を設けることなく、改修防水シートを既存の前記防水シートに接着して新防水層を形成することが可能となる。
従って、新しい防水シート固定金具を用意したり、用意したものを防水下地に取り付けたりしなくてもよくなり、材料コスト・施工コストの低減化を図ることが可能となる。
更には、新たに防水シート固定金具を設置しなくても防水シートを固定できるから、騒音発生の原因となっていた固定金具の固定作業を省略して、静かに防水層改修工事を進めることが可能となる。
【０００９】
ホットメルト接着用シートは、防水シート固定金具への防水シート（元々設置してある防水シートを指し、以後、単に改修前防水シートという）の固定部の上に位置させるから、改修防水シートと前記改修前防水シートとの接着部分が、防水シート固定金具上に位置することとなり、改修防水シートに対する浮き上げ力を、前記改修前防水シートを介して防水シート固定金具で直接に且つ安定的に支持することが可能となる。即ち、ホットメルト接着用シートの設置位置が、防水シート固定金具の直上から横ずれしている場合には、前記浮き上げ力が作用するにつれて、改修防水シートから前記改修前防水シートのホットメルト接着用シート接着部に浮き上げ力が作用し、改修前防水シートは、浮き上がりながら、防水シート固定金具で支持された別の位置で横移動を阻止する状態に位置規制されることとなり、改修防水シートの受け上げ阻止に関しては充分ではないのに対して、本発明の場合は、改修防水シートへの浮き上げ力の作用点と、防水シート固定金具による改修防水シートの支持点とが重なり、より効率よく改修防水シートの浮き上がりの防止を図ることが可能となる。
【００１１】
単一の防水シートによる防水層に比べて、より強力な防水効果を発揮することが可能となる。しかも、何れの防水シートも、例えば、貫通ボルト等の固定具を使用する支持形態をとらずに、接着によって防水下地に固定されているから、防水上、弱点となり易い固定用貫通孔を前記両防水シートに形成する必要がなく、各防水シートそのものの防水性能を、無駄なく発揮することが可能となる。
従って、より防水効果の高い防水層を形成することが可能となる。
【００１２】
尚、上述のように、図面との対照を便利にするために符号を記したが、該記入により本発明は添付図面の構成に限定されるものではない。
【００１３】
【発明の実施の形態】
以下に本発明の実施の形態を図面に基づいて説明する。尚、図面において従来例と同一の符号で表示した部分は、同一又は相当の部分を示している。
【００１４】
図４は、本発明の防水層改修方法を実施する前の建物の屋上スラブ１を示す断面図で、鉄筋コンクリート製のスラブ本体（防水下地に相当）２上に、防水シート固定金具３を介して改修前防水シート（第一防水シートに相当）４を接着して防水層Ｐ１を形成してある状況を示すものである。
【００１５】
前記スラブ本体２は、当該実施形態においては、上述のように屋上部分のスラブに該当し、鉄筋コンクリート構造のスラブの他、ＡＬＣ板を敷き並べて形成したスラブや、デッキプレートや金属折板とコンクリートを組み合わせて形成したスラブや、更には、それらの上に断熱層を積層させたもの等、様々な実施形態が挙げられる。
そして、スラブ本体２は、前記防水シート固定金具３を固定するためのビスＢを抜け止め状態に支持できるものであることが好ましい。
【００１６】
前記防水シート固定金具３は、例えば、図２・３に示すように、直径５０ｍｍ程度のステンレス鋼製円板の上面にポリエステル樹脂等の溶けて接着性を発揮する熱可塑性合成樹脂からなるホットメルト接着層Ｈを被覆したワッシャ本体３Ａによって構成してある。
また、ワッシャ本体３Ａはその中心にビス固定用の座繰り凹部５Ａ、及び、その底部分に固定用ビスＢの取付孔６が形成され、ワッシャ本体３Ａの上面は、座繰り凹部５Ａの周りに所定幅隔てて環状凹部５Ｂが形成されている。
尚、ワッシャ本体３Ａは、板金をプレス加工して図のような起伏形状に成形されており、前記座繰り凹部５Ａや環状凹部５Ｂ等の凹部５を形成してあることによって、平板のままより断面二次モーメントが増加し、薄板であっても強度の高いワッシャ本体を構成することが可能となっている。
また、前記ワッシャ本体３Ａの上面は、上述のホットメルト接着層Ｈを被覆して接着部７として構成してある。
そして、ワッシャ本体３Ａは、スラブ本体２上に、縦横に所定の間隔を開けた各位置に配置され、前記取付孔６を通してビス止めしてある。
【００１７】
前記改修前防水シート４は、例えば、ＰＶＣシートによって構成してあり、工場で所定幅寸法の長尺体防水シートを巻き取ってロール体を形成しておき、そのロール体を現場で広げながら配置し、隣接する各改修前防水シート４相互の側縁部どうしを接着することで大面積の防水シートとすることができる。勿論、予め、敷設する対象面積に合わせて一体品の防水シートを形成しておくものであってもよいし、また、素材に関しても、ＰＶＣ以外にも、ゴムやＴＰＥ（サーモ・プラスチック・エラストマ）製のシート、又は、その他の素材からなる防水シートであってもよい。
【００１８】
そして、スラブ本体２への改修前防水シート４の固定は、ワッシャ本体３Ａの上に被さった改修前防水シート４部分上方に磁気加熱装置をセットして、ワッシャ本体３Ａを磁気加熱することによって、前記ホットメルト接着層Ｈを溶かし、ワッシャ本体３Ａと改修前防水シート４とを接着することができる（図１・４参照）。
【００１９】
以上のような防水層Ｐ１も、耐久年が経過するに伴って、改修する必要があり、図１・５は、本発明の防水層改修方法の実施状況を示す説明図である。
防水層Ｐ１の改修手順は、改修前防水シート４の上（防水シート固定金具３への改修前防水シート４の固定部の上）に、電磁加熱によって発熱する発熱部８ａを備えたホットメルト接着用シート８を配置し、その上に改修用の改修防水シート（第二防水シートに相当）９を敷設し、改修防水シート９の上方から電磁加熱によって前記発熱部８ａを加熱することによって、前記ホットメルト接着用シート８を融かして前記改修防水シート９を前記防水シート４上に接着して新防水層Ｐ２を形成するものである。
【００２０】
因みに、前記ホットメルト接着用シート８は、図５に示すように、発熱部８ａに相当する金属箔の表裏両面に、夫々ホットメルト接着層Ｈをラミネートして構成してあり、前記改修前防水シート４と改修防水シート９との間に介在させた状態で、改修防水シート９の上方から電磁加熱することによって、前記金属泊が加熱され、その熱によって表裏両面のホットメルト接着層Ｈが融けて、両防水シート４・９を一体に接着することができる。
【００２１】
このようにして、防水層を改修することができる。また、改修後の防水構造については、改修防水シート９の下方に既存の改修前防水シート４が位置した二重の防水層となっており、しかも、スラブ本体２への固定は、何れの防水シートも、ワッシャ本体３Ａの上部に接着手段によって実施されているいるから、両防水シートに穴を開けない状態で防水層を構成でき、より信頼性の高い防水性を確保することが可能となる。しかも、改修の際に新たにワッシャ本体３Ａを設置することがなく、防水下地への穴明け作業を実施せずに、静かに、且つ、迅速に防水層を形成することが可能となる。
【００２２】
また、防水シート固定金具３に関して、防水シートの立ち上がり部分は、図６に示すような、固定棒３Ｂを使用することもできる。
この固定棒３Ｂは、三角筒部材で構成してあり、断面三角形の二つの直交辺の内の一方には、固定ビス挿通穴１０を設けてあり、この固定ビス挿通穴１０に固定ビスＢを挿通させて防水下地に固定することができる。また、断面三角形の斜辺には、前記挿通孔１０に固定ビスＢを挿通させて締付操作自在な操作穴１１を形成してある。そして、前記斜辺部分の表面に、前記ワッシャ本体３Ａと同様に、ホットメルト接着層Ｈを設けてあり、防水シートを被した後に電磁加熱によって接着させることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a waterproof layer repair method for repairing a waterproof layer formed by fixing a waterproof sheet with an adhesive on the upper surface of a waterproof sheet fixing bracket fixed on the waterproof base, and fixed on the waterproof base. The present invention relates to a waterproof structure in which a waterproof layer is fixed on a waterproof sheet fixing bracket.
[0002]
[Prior art]
Conventionally, as a waterproof layer repair method of this type, as shown in FIG. 7, the existing waterproof layer P1 is left as it is, and a new waterproof sheet fixing bracket 3 is disposed thereon, and already A waterproofing sheet fixing bracket 3 is fixed to the waterproof base 2 by driving a screw B so as to penetrate a certain waterproof sheet 4, and a new waterproof sheet 9 is fixed to the upper surface of the waterproof sheet fixing bracket 3 with an adhesive to form a waterproof layer. The method of renovation was taken.
In addition, as described above, the waterproof structure when the waterproof layer is modified among the conventional waterproof structures is such that the waterproof sheet 4 located on the waterproof base 2 side is penetrated to fix the waterproof sheet fixing bracket 3 with screws. In some cases, a new waterproof sheet 9 is bonded on the waterproof sheet fixing bracket 3.
Further, as a waterproof structure in the case of newly installing a waterproof layer among conventional waterproof structures, as shown in FIG. 8, a waterproof sheet fixing bracket 3 is fixed on a waterproof base 2, and a waterproof sheet 9 is provided on the upper surface thereof. It was a single layer waterproof structure.
[0003]
[Problems to be solved by the invention]
According to the conventional waterproof layer renovation method described above, when a waterproof sheet fixing bracket is newly fixed to a waterproof base, a screw (for example, a hole-in anchor or a concrete nail may be used) is used. However, it is necessary to drill a hole in the waterproof base with a drill etc. (When using a hole-in anchor or a concrete nail, it is necessary to drive it hard with a hammer). In this case, there is a problem that noise is generated. That is, when the waterproof layer is renovated while using a building, the noise tends to give unpleasant feelings to people on the lower floor.
And since fixing materials, such as a waterproof sheet fixing metal fitting and a screw, are needed newly, when the installation effort and the material to be used are considered, there exists a problem which tends to cause the increase in waterproofing layer repair cost.
[0004]
In addition, according to the waterproof structure in the case where the waterproof layer is modified among the conventional waterproof structures described above, the waterproof sheet located on the waterproof base side has a hole due to the penetration of the screw. The sheet cannot be expected to have a waterproof effect, and the waterproof effect of the entire waterproof layer is left only to the new waterproof sheet. Therefore, if a hole is made in a new waterproof sheet, the waterproof effect of the entire waterproof layer is lost, and there is a problem that it is difficult to expect a high safety factor for waterproofing.
In addition, among the conventional waterproof structures described above, the waterproof structure in the case of newly installing a waterproof layer is a one-layer waterproof structure in which a waterproof sheet is bonded and fixed to the upper surface of a waterproof sheet fixing bracket fixed on a waterproof base. In the unlikely event that a hole is formed in the waterproof sheet, the waterproof effect is lost, and there is a problem that it is difficult to expect a higher waterproof safety factor than the waterproof structure in the case where the above-described modification is performed.
[0005]
Accordingly, an object of the present invention is to provide a waterproof layer repairing method that can solve the above-mentioned problems and can perform waterproofing layer repair work without generating a large noise, and waterproofing that makes it easy to ensure a waterproof safety factor. It is in providing structure.
[0006]
[Means for Solving the Problems]
The characteristic means of the invention of claim 1 is a waterproof structure in which a waterproof sheet 4 is fixed to an upper surface of a waterproof sheet fixture 3 fixed on a waterproof base 2 with an adhesive as illustrated in FIGS. In the waterproof layer repairing method for repairing the layer P1, the hot melt bonding sheet 8 provided with a heat generating portion 8a that generates heat by electromagnetic heating on the fixing portion of the waterproof sheet 4 to the waterproof sheet fixing bracket is applied to the waterproof sheet. The sheet for hot melt bonding is arranged by laying a repair waterproof sheet 9 for repair on it, and heating the heat generating portion 8a by electromagnetic heating from above the repair waterproof sheet 9 8 is melted and the modified waterproof sheet 9 is bonded onto the waterproof sheet 4 to form a new waterproof layer P2.
[0007]
According to the characteristic means of the invention of claim 1, a hot melt adhesive sheet having a heat generating part that generates heat by electromagnetic heating is disposed on the waterproof sheet, and a repair waterproof sheet for repair is laid thereon. Since the heat generating part is heated by electromagnetic heating from above the repaired waterproof sheet, the hot melt adhesive sheet is melted and the repaired waterproof sheet is bonded onto the waterproof sheet to form a new waterproof layer. The new waterproof layer can be formed by bonding the repaired waterproof sheet to the existing waterproof sheet without newly providing a waterproof sheet fixing metal fitting.
Therefore, it is not necessary to prepare a new waterproof sheet fixing bracket or attach the prepared waterproof sheet to the waterproof base, and it is possible to reduce the material cost and the construction cost.
Furthermore, since the waterproof sheet can be fixed without installing a new waterproof sheet fixing bracket, the fixing work of the fixing bracket that caused noise generation can be omitted, and the waterproof layer repair work can be proceeded quietly. It becomes possible.
[0009]
E Ttomeruto bonding sheet (refer waterproof sheet that is originally installed, hereinafter simply repair the doorstep waterproof sheet) waterproof sheet to the waterproof sheet fixing bracket from is located on the fixed part of the the renovation waterproof sheet The adhesive part with the waterproof sheet before renovation is located on the waterproof sheet fixing bracket, and the lifting force against the modified waterproof sheet is directly and stably supported by the waterproof sheet fixing bracket via the waterproof sheet before repair. It becomes possible to do. That is, when the installation position of the hot-melt adhesive sheet is shifted laterally from directly above the waterproof sheet fixing bracket, the hot-melt adhesive sheet is attached from the modified waterproof sheet to the unmodified waterproof sheet as the lifting force acts. The lifting force acts on the sheet adhesion part, and the waterproof sheet before refurbishment is restricted to a state where it is prevented from lateral movement at another position supported by the waterproof sheet fixing bracket while floating. In the case of the present invention, the action point of the lifting force on the repaired waterproof sheet overlaps with the support point of the repaired waterproof sheet by the waterproof sheet fixing bracket, but it is more efficient. It is possible to prevent the repaired waterproof sheet from being lifted.
[0011]
Compared to the waterproof layer by single tarpaulin, it is possible to exert a stronger waterproof effect. In addition, since each waterproof sheet is fixed to the waterproof base by adhesion without taking a support form using, for example, a fixing bolt or the like, the fixing through-holes that are likely to be weak points are waterproofed. There is no need to form the waterproof sheet, and the waterproof performance of each waterproof sheet itself can be exhibited without waste.
Therefore, it is possible to form a waterproof layer having a higher waterproof effect.
[0012]
In addition, as mentioned above, although the code | symbol was written in order to make contrast with drawing convenient, this invention is not limited to the structure of an accompanying drawing by this entry.
[0013]

In the present embodiment, the slab body 2 corresponds to a roof slab as described above. In addition to a slab having a reinforced concrete structure, the slab body 2 includes a slab formed by laying an ALC plate, a deck plate, a metal folded plate, and concrete. Various embodiments, such as a slab formed in combination, or a laminate in which a heat insulating layer is laminated thereon, can be mentioned.
And it is preferable that the slab main body 2 can support the screw | thread B for fixing the said waterproof sheet fixing metal fitting 3 in the retaining state.
[0016]
For example, as shown in FIGS. 2 and 3, the waterproof sheet fixing bracket 3 is a hot melt made of a thermoplastic synthetic resin that melts polyester resin or the like and exhibits adhesiveness on the upper surface of a stainless steel disc having a diameter of about 50 mm. The washer body 3A is coated with an adhesive layer H.
Further, the washer body 3A is formed with a countersink recess 5A for fixing the screw at the center and a mounting hole 6 for the fixing screw B at the bottom thereof, and the upper surface of the washer body 3A is around the countersink recess 5A. An annular recess 5B is formed at a predetermined width.
The washer body 3A is formed into a undulating shape as shown in the figure by pressing a sheet metal, and is formed as a flat plate by forming the recessed portions 5 such as the countersink recessed portion 5A and the annular recessed portion 5B. The sectional moment of inertia increases, and it is possible to construct a washer body having high strength even if it is a thin plate.
The upper surface of the washer body 3A is configured as an adhesive portion 7 by covering the hot melt adhesive layer H described above.
The washer body 3 </ b> A is disposed on the slab body 2 at respective positions at predetermined intervals in the vertical and horizontal directions, and is screwed through the mounting holes 6.

The pre-repair waterproof sheet 4 is constituted by, for example, a PVC sheet, and rolls a long waterproof sheet having a predetermined width at a factory to form a roll body, which is arranged while spreading the roll body in the field. And it can be set as a waterproof sheet of a large area by adhere | attaching the adjacent edge parts of each before-repair waterproof sheet 4 mutually. Of course, it is also possible to form an integral waterproof sheet in advance according to the area to be laid, and in addition to PVC, rubber and TPE (Thermo Plastic Elastomer) may be used. It may be a sheet made of water or a waterproof sheet made of other materials.
[0018]
And the fixing of the waterproof sheet 4 before repair to the slab body 2 is carried out by setting a magnetic heating device above the waterproof sheet 4 part before repair covered on the washer body 3A and magnetically heating the washer body 3A. The hot melt adhesive layer H can be melted to bond the washer body 3A and the waterproof sheet 4 before repair (see FIGS. 1 and 4).
[0019]
The waterproof layer P1 as described above also needs to be repaired as the endurance year elapses, and FIGS. 1 and 5 are explanatory diagrams showing the implementation status of the waterproof layer repair method of the present invention.
The refurbishment procedure of the waterproof layer P1 is performed by hot-melt bonding provided with a heat generating portion 8a that generates heat by electromagnetic heating on the pre-renovation waterproof sheet 4 (on the fixing portion of the waterproof sheet 4 before remodeling to the waterproof sheet fixing bracket 3) By disposing a repair waterproof sheet (corresponding to a second waterproof sheet) 9 for repairing, and heating the heat generating portion 8a by electromagnetic heating from above the repair waterproof sheet 9, The hot-melt adhesive sheet 8 is melted and the modified waterproof sheet 9 is adhered onto the waterproof sheet 4 to form a new waterproof layer P2.
[0020]
Incidentally, as shown in FIG. 5, the hot melt adhesive sheet 8 is formed by laminating a hot melt adhesive layer H on both front and back surfaces of a metal foil corresponding to the heat generating portion 8a. The metal stay is heated by electromagnetic heating from above the modified waterproof sheet 9 in a state of being interposed between the sheet 4 and the modified waterproof sheet 9, and the hot melt adhesive layer H on both the front and back surfaces is melted by the heat. Thus, both waterproof sheets 4 and 9 can be bonded together.
[0021]
In this way, the waterproof layer can be repaired. In addition, the waterproof structure after the repair is a double waterproof layer in which the existing waterproof sheet 4 before the repair is positioned below the repair waterproof sheet 9, and any waterproofing can be fixed to the slab body 2. Since the sheet is also implemented on the upper part of the washer main body 3A by an adhesive means, a waterproof layer can be formed without making a hole in both waterproof sheets, and a more reliable waterproof property can be secured. . In addition, it is possible to form a waterproof layer quietly and quickly without newly installing the washer body 3A at the time of refurbishment and without performing a drilling operation on the waterproof base.
[0022]
Further, with respect to the waterproof sheet fixing bracket 3, a fixing rod 3 </ b> B as shown in FIG. 6 can be used for the rising portion of the waterproof sheet.
