Description

本発明は、環境に悪影響を及ぼすことがなく、しかも、延ばす際にしわや切れ等が生じにくく、貼り直し性に優れる天窓水切り止水シートに関する。   The present invention relates to a skylight draining water-stopping sheet that does not adversely affect the environment, is less likely to be wrinkled or cut when stretched, and has excellent re-stickability.

従来、傾斜屋根に天窓を設置する場合には、天窓の枠材（縦枠、上枠、下枠）に水切りを取り付け、この水切りの上に瓦等の屋根材を葺いていくのが一般的である。
但し、下枠の水切りに関しては、上から流れる雨水を下枠の下に位置する屋根瓦の上に流す必要性から、当該水切りに止水シートを連続させて、この止水シートを当該瓦の上に貼り付けている。 Conventionally, when installing skylights on sloped roofs, it is common to install a drainer on the frame material (vertical frame, upper frame, lower frame) of the skylight, and spread roof materials such as tiles on this drainer. It is.
However, with regard to draining the lower frame, since it is necessary to flow rainwater flowing from above onto the roof tiles located under the lower frame, a water-stop sheet is continuously connected to the drainer, and the water-stop sheet is attached to the roof tile. It is pasted on top.

従来の止水シートは、加工の容易性から鉛板で構成されていたが、鉛板を用いた場合には、固定金具の接合穴、水切り板と鉛板との接合部、鉛板と屋根瓦との接合部を、コーキングなどにより止水しなければならず、施工時の工程が多い上に、防水性が十分でないという問題があった。また、鉛は長期間、風雨に曝されると、雨水に溶け出し環境に悪影響を与えるという問題があった。   Conventional water-stop sheets consisted of lead plates for ease of processing. However, when lead plates are used, joint holes for fixing brackets, joints between draining plates and lead plates, lead plates and roofs There was a problem that the joint part with the tile had to be stopped by caulking or the like, and there were many steps during construction, and the waterproofness was not sufficient. In addition, when lead is exposed to wind and rain for a long period of time, there is a problem that it dissolves in rainwater and adversely affects the environment.

これを解消するため、加硫ゴムシートの一方の面に、接着剤層を介して金属シートが貼り合わされた積層シートであって、該積層シートに波付け加工が施されて波板状とされた防水シートが提案されている（例えば、特許文献１）。
特開２００３−１０５９３６号公報 In order to solve this problem, a laminated sheet in which a metal sheet is bonded to one surface of a vulcanized rubber sheet via an adhesive layer, and the laminated sheet is corrugated to form a corrugated sheet. A waterproof sheet has been proposed (for example, Patent Document 1).
JP 2003-105936 A

しかし、従来の防水シートは、加硫ゴムシートの一方の面に、接着剤層を介して金属シートが貼り合わされ、この金属シートに、屋根瓦に対する粘着シートが積層されるので、その積層構造が複雑になると共に、防水シートを叩いて延ばす際等に金属シートによれやしわができたり、金属シートが切れてしまうことがあった。また、防水シートの貼り直し時に、材料破壊が生じるおそれや粘着力が低下してしまうおそれがあり、防水シート自体を交換しなければならなくなったり、防水シートの剥がれが生じてしまうおそれがあった。   However, a conventional waterproof sheet has a metal sheet bonded to one surface of a vulcanized rubber sheet via an adhesive layer, and an adhesive sheet for the roof tile is laminated on this metal sheet. In addition to being complicated, the metal sheet sometimes wrinkles or wrinkles when the waterproof sheet is struck and extended, or the metal sheet sometimes breaks. In addition, when the waterproof sheet is reapplied, there is a risk that the material may be destroyed or the adhesive strength may be reduced, and the waterproof sheet itself must be replaced or the waterproof sheet may be peeled off. .

そこで、本発明の目的は、上述の課題を解消し、環境に悪影響を及ぼすことがなく、しかも、延ばす際にしわや切れ等が生じにくく、貼り直し性に優れる天窓水切り止水シートを提供することにある。   Accordingly, an object of the present invention is to provide a skylight draining water-stopping sheet that eliminates the above-mentioned problems, does not adversely affect the environment, and is less likely to be wrinkled or cut when extended, and has excellent re-stickability. There is.

上記課題を解決するため、本発明は、天窓の水切りに一側部が連なり他側部が屋根材に貼られる止水シートを備え、この止水シートが、金属板と、この金属板に積層されて屋根材に対する接着剤として機能すると共に、厚さが０．４〜１．１ｍｍのブチルゴム層とを備えたことを特徴とする。この発明によれば、厚さが０．４〜１．１ｍｍのブチルゴム層を、屋根材に対する接着剤に使用しているため、鉛を含まない金属板を用いても、止水シートを延ばす際にしわや材料破壊が生じにくく、十分な接着力を持たせることができ、従って、何回でも貼り直しが可能になる。   In order to solve the above-mentioned problem, the present invention comprises a water-stop sheet in which one side is connected to the draining of a skylight and the other side is affixed to a roofing material. In addition to functioning as an adhesive for the roofing material, a butyl rubber layer having a thickness of 0.4 to 1.1 mm is provided. According to the present invention, since a butyl rubber layer having a thickness of 0.4 to 1.1 mm is used as an adhesive for a roofing material, even when a metal plate not containing lead is used, the waterproof sheet is extended. Wrinkles and material destruction do not easily occur, and a sufficient adhesive force can be imparted. Therefore, it is possible to reapply any number of times.

この場合において、前記ブチルゴムが、１５．３〜１５．７重量％の粘着付与剤を含むようにしてもよい。粘着付与剤を１５．３〜１５．７重量％含むので、ブチルゴムに十分な耐候性及び接着力をもたせることが可能になる。
また、この場合において、前記ブチルゴムが、２．８〜３．２重量％の可塑剤を含むようにしてもよい。可塑剤を２．８〜３．２重量％含むので、ブチルゴム層の硬さを、接着性に優れ、かつ、金属板の切れが生じにくい適度な硬さにすることが可能になる。 In this case, the butyl rubber may contain 15.3 to 15.7% by weight of a tackifier. Since the tackifier is contained in an amount of 15.3 to 15.7% by weight, the butyl rubber can be provided with sufficient weather resistance and adhesive strength.
In this case, the butyl rubber may contain 2.8 to 3.2% by weight of a plasticizer. Since the plasticizer is contained in an amount of 2.8 to 3.2% by weight, the hardness of the butyl rubber layer can be set to an appropriate hardness that is excellent in adhesiveness and hardly breaks the metal plate.

本発明は、止水シートが、金属板と、この金属板に積層されて屋根材に対する接着剤として機能すると共に、厚さが０．４〜１．１ｍｍのブチルゴム層とを備えるので、鉛を含まない金属板を用いても、止水シートを延ばす際にしわや材料破壊が生じにくく、十分な接着力を持たせることができ、従って、何回でも貼り直しが可能になる。   In the present invention, since the water-stop sheet includes a metal plate and a butyl rubber layer having a thickness of 0.4 to 1.1 mm, which is laminated on the metal plate and functions as an adhesive for the roofing material, Even when a metal plate that is not included is used, wrinkles and material breakage are less likely to occur when the waterproof sheet is extended, and a sufficient adhesive force can be imparted.

以下、図面を参照して本発明の一実施形態について説明する。
図１は本発明の実施形態に係る止水シートを使用した天窓を示す図であり、図２はその断面図である。
この天窓１０は、傾斜屋根１１に設置され、この天窓１０の枠材（縦枠、上枠１２（図２）、下枠１３（図２））には、傾斜屋根１１の野地板１５上に敷設された防水シート１６の上から水切り２０が各々取り付けられ、この水切り２０の上に屋根瓦（屋根材）２１が葺かれる。
また、下枠１３の水切り２０ａには、その上面に止水シート３０の一側部が貼られ、この止水シート３０の他側部が、水切り２０ａの下に位置する屋根瓦２１ａの上面に貼られることによって、天窓１０から水切り２０ａに流れた雨水が当該シート３０の上面を流れて軒下側の屋根瓦２１ａ（図１）の上に流れるように施工されている。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a view showing a skylight using a waterproof sheet according to an embodiment of the present invention, and FIG. 2 is a sectional view thereof.
The skylight 10 is installed on the inclined roof 11, and the frame material (vertical frame, upper frame 12 (FIG. 2), lower frame 13 (FIG. 2)) of the skylight 10 is placed on the field plate 15 of the inclined roof 11. Drainers 20 are respectively attached from the laid waterproof sheet 16, and roof tiles (roofing material) 21 are spread on the drainers 20.
Moreover, one side part of the water stop sheet 30 is affixed to the upper surface of the drainer 20a of the lower frame 13, and the other side part of the water stop sheet 30 is on the upper surface of the roof tile 21a located under the drainer 20a. By being affixed, it is constructed so that rainwater flowing from the skylight 10 to the drainer 20a flows on the upper surface of the sheet 30 and flows onto the roof tile 21a (FIG. 1) below the eaves.

この止水シート３０は、図３（Ａ）〜（Ｃ）に示すように、波付け加工が施されて波板状に形成され、その裏面に接着面が形成され、かかる接着面には、剥離紙３１が設けられている。また、このシート３０には、長手方向に沿って折り目加工部３２が設けられ、この折り目加工部３２の中心線Ｌ１に沿って剥離紙３１の切れ目が設けられている。これにより、この切れ目を境に一方の剥離紙３１ａをはがしてシート３０の一部の接着面Ｍ１だけを露出させ、折り目加工部３２を基準に当該シート３０の貼り付け位置を合わすことができ、更に、このシート３０は、他方の剥離紙３１ｂがシート３０の側縁から飛び出し、この剥離紙３１ｂを容易にはがし易くなっている。なお、本実施形態では、剥離紙３１ｂをはがした際の接着面が、図３（Ｂ）に示す領域Ｒ１を除く接着面Ｍ２であり、この領域Ｒ１には接着面が形成されていない場合を例示しているが、この領域Ｒ１にも接着面を設け、シート３０の裏面全体を接着面にしてもよい。   As shown in FIGS. 3 (A) to (C), the water blocking sheet 30 is corrugated and formed into a corrugated plate, and an adhesive surface is formed on the back surface thereof. A release paper 31 is provided. Further, the sheet 30 is provided with a crease processing portion 32 along the longitudinal direction, and a cut line of the release paper 31 is provided along the center line L1 of the crease processing portion 32. Thereby, one release paper 31a is peeled off at the boundary, and only a part of the adhesive surface M1 of the sheet 30 is exposed, and the attachment position of the sheet 30 can be adjusted based on the crease processing portion 32, Further, in this sheet 30, the other release paper 31b jumps out from the side edge of the sheet 30, and the release paper 31b can be easily peeled off. In this embodiment, the adhesive surface when the release paper 31b is peeled off is the adhesive surface M2 excluding the region R1 shown in FIG. 3B, and no adhesive surface is formed in this region R1. However, an adhesive surface may also be provided in this region R1, and the entire back surface of the sheet 30 may be an adhesive surface.

この止水シート３０は、図４に示すように、アルミニウム製の金属板（金属層）４０を備え、この金属板４０の表面４０ａには、フッ素樹脂フィルム等の耐候性及び撥水性を有するフィルム４１が設けられ、裏面４０ｂには、ブチルゴム層４２が設けられている。
このブチルゴム層４２は、ブチルゴムをベースとして、粘着付与剤及び可塑剤等を混合した材料から形成され、粘着付与剤によりそれ自体が接着剤として機能し、この接着機能により金属板４０に張り合わされている。また、剥離紙３１は、このブチルゴム層４２の金属板４０と反対側の面に張り合わされ、これによって、この止水シート３０は、このブチルゴム層４２自体の接着機能により水切り２０ａや屋根瓦２１ａに貼り付けられる。 As shown in FIG. 4, the water-stop sheet 30 includes an aluminum metal plate (metal layer) 40, and a film having weather resistance and water repellency such as a fluororesin film on the surface 40 a of the metal plate 40. 41 is provided, and a butyl rubber layer 42 is provided on the back surface 40b.
The butyl rubber layer 42 is formed of a material in which a tackifier and a plasticizer are mixed based on butyl rubber. The butyl rubber layer 42 functions as an adhesive by the tackifier and is bonded to the metal plate 40 by the adhesive function. Yes. Further, the release paper 31 is attached to the surface of the butyl rubber layer 42 opposite to the metal plate 40, whereby the waterproof sheet 30 is attached to the drainer 20a or the roof tile 21a by the bonding function of the butyl rubber layer 42 itself. It is pasted.

この止水シート３０を施工する場合、まず、このシート３０を木づちで叩く等して平らにし、次に、図５（Ａ）に示すように、シート３０の一側部の剥離紙３１ａ（図１）をはがして、下枠１３側の水切り２０ａに密着するように貼り付けてシート３０を位置決めし、次に、残る剥離紙３１ｂをはがして、シート３０を瓦２１ａの上方にもっていき、図５（Ｂ）に示すように、シート３０を木づちで叩いて屋根瓦２１ａに沿って変形させ、シート３０を屋根瓦２１ａに密着させる。これによって、図５（Ｃ）に示すように、止水シート３０が、各々形状が異なる水切り２０ａ及び屋根瓦２１ａに隙間なく密着される。   When the waterproof sheet 30 is constructed, first, the sheet 30 is flattened by hitting it with a hammer, and then, as shown in FIG. 5A, the release paper 31a ( 1) is peeled off and attached so as to be in close contact with the drainer 20a on the lower frame 13 side, and then the sheet 30 is positioned, then the remaining release paper 31b is peeled off, and the sheet 30 is moved above the roof tile 21a As shown in FIG. 5 (B), the sheet 30 is hit with a wooden stick to be deformed along the roof tile 21a, and the sheet 30 is brought into close contact with the roof tile 21a. Thereby, as shown in FIG.5 (C), the water stop sheet | seat 30 closely_contact | adheres to the drainer 20a and the roof tile 21a from which shapes differ, respectively.

ところで、上記施工時において、止水シート３０を叩いて平らに延ばしたり、屋根瓦２１ａに沿って変形させる際等に、その際の負荷でブチルゴム層４２に材料破壊が生じたり、金属板４０に切れや破れが生じるおそれがある。また、ブチルゴム層４２の接着力が不足していた場合には、特に貼り直しをすると、シート３０の浮き上がりや剥がれが生じやすくなる。   By the way, at the time of the above construction, when the waterproof sheet 30 is struck to be flattened or deformed along the roof tile 21a, the butyl rubber layer 42 is destroyed by the load at that time, or the metal plate 40 is damaged. Cutting or tearing may occur. In addition, when the adhesive force of the butyl rubber layer 42 is insufficient, the sheet 30 is likely to be lifted or peeled off particularly when it is reattached.

そこで、本実施形態では、ブチルゴム層４２の厚さｔを以下のように設定すると共に、粘着付与剤及び可塑剤の混合比率を以下のように設定している。なお、金属板４０は例えば０．２ｍｍの厚さに形成されている。
図６は、ブチルゴム層４２の厚さｔの試験結果を示している。図６に示すように、ブチルゴム層４２の厚さｔが１．１ｍｍを超えると、ブチルゴム層４２が厚すぎるために、貼り直し時にブチルゴム層４２の材料破壊が生じると共に、シート３０を延ばした際に金属板（金属層）４０に大きいよれやしわが生じることが分かった。一方、ブチルゴム層４２の厚さが０．４ｍｍを下回ると、接着力より金属板４０の弾性力が上回ってしまい、シート３０の剥がれや浮き上がりが生じやすくなることが分かった。
そこで、本実施形態では、ブチルゴム層４２の厚さｔを０．４〜１．１ｍｍの範囲に設定し、シート３０の剥がれ、貼り直し時の材料破壊、及び、金属板４０の切れ、破れ等を回避し、シート３０の施工性を向上させている。
但し、ブチルゴム層の厚さｔを０．４ｍｍに設定した場合、製作時の誤差によって厚さが０．４ｍｍ以下の部分が存在するおそれがあり、また、厚さｔを大きくするほど、シート３０が重くなると共に、材料コストが高くなるため、より好ましくは、厚さｔは０．５〜１．０ｍｍの範囲に設定することが望ましい。 Therefore, in the present embodiment, the thickness t of the butyl rubber layer 42 is set as follows, and the mixing ratio of the tackifier and the plasticizer is set as follows. The metal plate 40 is formed to a thickness of 0.2 mm, for example.
FIG. 6 shows a test result of the thickness t of the butyl rubber layer 42. As shown in FIG. 6, when the thickness t of the butyl rubber layer 42 exceeds 1.1 mm, the butyl rubber layer 42 is too thick. It was found that large wrinkles and wrinkles were generated in the metal plate (metal layer) 40. On the other hand, it was found that when the thickness of the butyl rubber layer 42 is less than 0.4 mm, the elastic force of the metal plate 40 exceeds the adhesive force, and the sheet 30 is likely to be peeled off or lifted.
Therefore, in the present embodiment, the thickness t of the butyl rubber layer 42 is set in the range of 0.4 to 1.1 mm, the sheet 30 is peeled off, the material is destroyed when reattached, and the metal plate 40 is cut and broken. The workability of the sheet 30 is improved.
However, when the thickness t of the butyl rubber layer is set to 0.4 mm, there is a possibility that a portion having a thickness of 0.4 mm or less exists due to an error in manufacturing, and as the thickness t is increased, the sheet 30 is increased. However, it is more desirable to set the thickness t in the range of 0.5 to 1.0 mm.

また、図７は、本実施形態に係るブチルゴム層４２の組成（配合比率）の一例を示す図である。実験によると、ブチルゴム層４２は、粘着付与剤が１５．７重量％を超えると、ブチルゴム層４２の耐候性が低下する等の悪影響が生じてしまい、一方、１５．３重量％を下回ると、ブチルゴム層４２の接着力が不足して屋根瓦から剥がれ易くなることが分かった。
そこで、本実施形態では、十分な耐候性及び接着力を持たせるために、粘着付与剤を１５．３〜１５．７重量％の範囲としており、より好ましくは、図７に例示するように１５．５重量％を最適値としている。 FIG. 7 is a diagram showing an example of the composition (mixing ratio) of the butyl rubber layer 42 according to the present embodiment. According to experiments, when the tackifier is more than 15.7% by weight, the butyl rubber layer 42 has an adverse effect such as a decrease in the weather resistance of the butyl rubber layer 42, whereas when it is less than 15.3% by weight, It was found that the adhesive force of the butyl rubber layer 42 was insufficient and the butyl rubber layer 42 was easily peeled off from the roof tile.
Therefore, in the present embodiment, in order to provide sufficient weather resistance and adhesive strength, the tackifier is in the range of 15.3 to 15.7% by weight, and more preferably 15 as illustrated in FIG. .5% by weight is the optimum value.

さらに、ブチルゴム層４２の可塑剤に関しては、３．２重量％を超えると、ブチルゴム層４２が硬くなり過ぎて接着力が低下してしまい、一方、２．８重量％を下回ると、ブチルゴム層４２が柔らかくなり過ぎ、シート３０が予想以上に変形して金属板４０が切れやすくなることが分かった。
そこで、本実施形態では、可塑剤を２．８〜３．２重量％の範囲としており、より好ましくは、図７に例示するように３．０重量％を最適値としている。 Further, regarding the plasticizer of the butyl rubber layer 42, if the amount exceeds 3.2% by weight, the butyl rubber layer 42 becomes too hard and the adhesive strength is reduced. On the other hand, if the amount is less than 2.8% by weight, the butyl rubber layer 42 is reduced. It became clear that the sheet 30 was deformed more than expected and the metal plate 40 was easily cut.
Therefore, in the present embodiment, the plasticizer is in the range of 2.8 to 3.2% by weight, and more preferably, 3.0% by weight is the optimum value as illustrated in FIG.

以上説明したように、本構成では、止水シート３０を、金属板４０と、粘着付与剤を混合して接着力を持たせたブチルゴム層４２との積層構造としたので、ブチルゴム層４２自体の接着力によりブチルゴム層４２を金属板４０に張り合わせることができ、しかも、このブチルゴム層４２の接着力で当該シート３０を水切り２０ａや屋根瓦２１ａに隙間なく貼り付けることができる。
しかも、このブチルゴム層４２の厚さを０．４〜１．１ｍｍとしたので、このシート３０を延ばす際にしわや切れ等が生じにくくなり、屋根瓦２１ａの形状に容易になじませることができ、貼り直しの頻度を低減できる他、十分な接着力を持たせることができ、張り直しを行ってもシート３０の浮き上がりや剥がれが防止される。
また、ブチルゴム層４２が１５．３〜１５．７重量％の粘着付与剤を含むようにしたので、ブチルゴム層４２に十分な耐候性及び接着力を持たせることができ、さらに、ブチルゴム層４２が、２．８〜３．２重量％の可塑剤を含むようにしたので、ブチルゴム層４２の硬さを、接着力に優れ、かつ、金属板４０の切れが生じにくい適度な硬さにすることが可能になる。また、本構成では、鉛を使用しないため、環境に悪影響を及ぼすことがない。 As described above, in this configuration, the water-stop sheet 30 has a laminated structure of the metal plate 40 and the butyl rubber layer 42 mixed with the tackifier to give an adhesive force. The butyl rubber layer 42 can be bonded to the metal plate 40 by the adhesive force, and the sheet 30 can be attached to the drainer 20a and the roof tile 21a without a gap by the adhesive force of the butyl rubber layer 42.
In addition, since the thickness of the butyl rubber layer 42 is set to 0.4 to 1.1 mm, the sheet 30 is less likely to be wrinkled or cut when extended, and can be easily adapted to the shape of the roof tile 21a. In addition to reducing the frequency of re-sticking, a sufficient adhesive force can be imparted, and the sheet 30 can be prevented from being lifted or peeled off even when re-stretching.
Further, since the butyl rubber layer 42 contains 15.3 to 15.7% by weight of a tackifier, the butyl rubber layer 42 can be provided with sufficient weather resistance and adhesive force. Since 2.8 to 3.2% by weight of a plasticizer is included, the hardness of the butyl rubber layer 42 is set to an appropriate hardness that is excellent in adhesive force and is difficult to cause the metal plate 40 to be cut. Is possible. Moreover, in this structure, since lead is not used, there is no bad influence on the environment.

上述した実施形態は、あくまでも本発明の一態様を示すものであり、本発明の範囲内で任意に変形が可能である。例えば、上述の実施形態では、金属板４０にアルミニウム板を用いる場合について述べたが、これ以外の鉛を含まない金属板を用いてもよく、また、止水シート３０を、天窓１０の下側に配置するだけでなく、その他の場所に貼り付けてもよい。   The above-described embodiments merely show one aspect of the present invention, and can be arbitrarily modified within the scope of the present invention. For example, in the above-described embodiment, the case where an aluminum plate is used as the metal plate 40 has been described. However, other metal plates that do not contain lead may be used. In addition to being placed in, it may be pasted in other places.
