Description

本願考案は、建築物の屋根、特に勾配屋根に葺かれる防火防水シートに関するものである。   The present invention relates to a fireproof / waterproof sheet that is placed on a roof of a building, particularly a sloped roof.

一般家屋の勾配屋根は、通常、粘土瓦、スレート瓦、カラー鉄板などで屋根葺きされており、一部寒冷地域ではアスファルトルーフィングや合成高分子ルーフィングも用いられている。これら屋根葺き材の下には防水シートなどの防水材を施すことが一般的であるが、昨今では、屋根の軽量化、耐寒性、に対する要請、とりわけ延焼防止などの理由から屋根の耐火性能に対する要請が高まっていることもあり、合成樹脂発泡形成体を用いた断熱材の上に塩化ビニル樹脂製の防水シートを固定する屋根葺き工法なども提案されている。   The sloped roofs of ordinary houses are usually roofed with clay tiles, slate tiles, colored iron plates, etc., and asphalt roofing and synthetic polymer roofing are also used in some cold areas. Under these roofing materials, it is common to apply waterproofing materials such as waterproof sheets, but nowadays, there is a demand for roof weight reduction, cold resistance, especially for fireproof performance of the roof due to reasons such as prevention of fire spread. Due to the increasing demand, a roofing method for fixing a waterproof sheet made of a vinyl chloride resin on a heat insulating material using a synthetic resin foam formed body has been proposed.

このように、屋根の防火方法や防水方法についてはいくつか提案があるものの、粘土瓦、スレート瓦、カラー鉄板など屋根材そのものに代わる提案は少なく、屋根材の自重が比較的重いために家全体の耐震性に影響を及ぼすこと、台風などの強風により飛散すること、など種々の問題は解決されなかった。
本願考案の課題は、これら諸問題を解決すると共に防火性、防水性に優れた屋根葺き用防火防水シートを実現することにある。 In this way, although there are some proposals for roof fire prevention and waterproofing methods, there are few alternatives to the roof material itself such as clay tile, slate tile, color iron plate, etc., and the weight of the roof material is relatively heavy, so the whole house Various problems, such as affecting the earthquake resistance of the aircraft and scattering by strong winds such as typhoons, have not been solved.
An object of the present invention is to realize a fireproof waterproof sheet for roofing that solves these problems and is excellent in fireproofing and waterproofing.

本願考案は、防水シートに防火性を付加した屋根葺き用防火防水シートであって、柔軟性や施工性に富み、従来の屋根構造よりも軽量化できるものを提供するものである。   The present invention provides a fireproof waterproof sheet for roofing in which fire resistance is added to a waterproof sheet, which is rich in flexibility and workability and can be reduced in weight compared to a conventional roof structure.

本願考案の屋根葺き用防火防水シートは、請求項１記載のように、屋根葺き用防水シートにおいて、耐火性の芯材の表裏両面が、難燃剤添加配合の塩化ビニル系の防水シート材料で被覆され、前記芯材と前記防水シート材料とがシート状又は板状に加熱圧着され、前記芯材を被覆する前記防水シート材料の表面に、不燃性又は、不燃性及び防錆性のある金属粒子を溶射したものである。請求項２記載のように、前記屋根葺き用防火防水シートにおいて、塩化ビニル系の防水シート材料に添加配合する難燃剤を炭酸カルシウム又は三酸化アンチモンとすることができる。また請求項３記載のように、溶射する不燃性又は、不燃性及び防錆性のある金属粒子を不燃アルミニウムと亜鉛の合金、又はアルミニウムとすることができる。   The fireproof waterproof sheet for roofing according to the present invention is the roofing waterproof sheet according to claim 1, wherein both front and back surfaces of the fireproof core material are covered with a vinyl chloride waterproof sheet material containing a flame retardant. The core material and the waterproof sheet material are heat-pressed into a sheet shape or a plate shape, and the surface of the waterproof sheet material covering the core material is nonflammable or nonflammable and rustproof metal particles. Is sprayed. As described in claim 2, in the fireproof waterproof sheet for roofing, the flame retardant added to the vinyl chloride waterproof sheet material can be calcium carbonate or antimony trioxide. In addition, as described in claim 3, the nonflammable or nonflammable and rustproof metal particles to be sprayed can be an incombustible aluminum / zinc alloy or aluminum.

本願考案の屋根葺き用防火防水シートは、請求項４記載のように、前記屋根葺き用防火防水シートの表面又は、表面及び裏面の周縁に不燃性又は、不燃性及び防錆性のある金属粒子を溶射しない継ぎ手しろを設けることが可能であり、さらに、屋根葺き用防火防水シートの表面に模様や滑り止め加工を施すこともできる。   The fireproof waterproof sheet for roofing according to the present invention is a metal particle that is nonflammable or nonflammable and rustproof on the surface of the roofing fireproof waterproof sheet or the periphery of the front and back surfaces, as claimed in claim 4. It is possible to provide a joint margin that does not spray the film, and it is also possible to apply a pattern or a non-slip process to the surface of the fireproof waterproof sheet for roofing.

本願考案の屋根葺き用防火防水シートは、次の効果がある。
（１）芯材の表裏両面が難燃剤添加配合の塩化ビニル系の防水シート材料で被覆されているため防水機能がある。
（２）防水シート材料の表面に不燃性の金属溶射を施し、防水シート材料自身にも難燃剤を添加配合してあるため、屋根の防火試験としてＪＩＳ等で行われている「飛び火試験」には全く問題なく、もちろん着火、延焼、変形もなく、２０分以内であれば直接火炎があたっても着火しない耐火材に近いものであり、防火機能に優れる。
（３）塩化ビニル系の防水シート材料で被覆されているため、長時間にわたって高温火炎に触れると塩素系の消火ガスが発生して屋根下地材の延焼を抑制することができる。
（４）粘土瓦などの屋根材は自重が比較的重く家全体の耐震性に影響を与えるため耐震性に問題があるが、本願考案の屋根葺き用防火防水シートは軽量（粘土瓦の約１／２０〜１／１５、スレート瓦の約１／１０、カラー鉄板の約１／２）であることから、これを用いると屋根全体としても軽量化され耐震性に優れる。
（５）粘土瓦、スレート瓦やカラー鉄板などは、寒冷地方での凍結融解による防水性の問題がある。一方、本願考案の屋根葺き用防火防水シートには重ね継ぎ手しろがあり、その部分は金属溶射されずに塩化ビニル系シートが表面に露出しているため防火防水シートどうしの固定（連結）はこの継ぎ手しろを重ねた面溶接が可能で、確実に接合され屋根全体としてもより防水性・耐候性の高い耐久性あるものとできる。
（６）また、本願考案の屋根葺き用防火防水シートの場合、例えば塩化ビニル鋼板などの屋根下地材への固定は、防火防水シートの裏側をこの下地材に面溶接することで行い、接着部分が密着して確実に固定されるため、屋根全体としてもより防水性・耐候性の高い耐久性あるものとなる。またこの場合、防火防水シートの端部を屋根下地の裏側に巻き込んで、同じく面溶接により固定することも可能で、より一層防水性が高まる。
（７）粘土瓦、スレート瓦やカラー鉄板などは、台風などの強風による飛来の問題がある。一方、本願考案の屋根葺き用防火防水シートの場合、上記のとおり、接合部は面溶接のため隙間がなく接合され、また温度変化や水浸漬などに対しても半永久的にこの接合が持続し、屋根下地材にも確実に固定できるので、台風など強風の影響をうけにくい。
（８）そのほかカラー鉄板は、塩害による錆びの問題、風雨時の騒音の問題があるが、本願考案の屋根葺き用防火防水シートは錆びに強く、風雨時の音も比較的小さい。
（９）薄肉のシート形状又は板状であるため軽量であり、かつ柔軟性もあるので施工性に富む。
（１０）シート材料に伸び特性のある塩化ビニル樹脂を使用し、薄いシート状あるいは板状にしてあるので、屋根下地材の動きにも追随し易く、屋根葺き作業が容易になる。
（１１）例えば凸凹仕上げ等を施すことが可能で、シート上に乗って施工する作業員の安全に寄与することができる。
（１２）表面を各種柄や色彩の模様で飾って個性的な意匠とすることができるので、葺いたときに屋根が変化に富んだものとなる。
（１３）さらに、耐火遮炎層などの中間層を必要とする３層構造に比べると、従来どおり断熱材と防水シートの２層構造とすることが可能であるため、この点でも、材料費、施工費ともに経済的であり、軽量であって地震による影響が軽減できる。 The fireproof waterproof sheet for roofing of the present invention has the following effects.
(1) Since both the front and back surfaces of the core material are covered with a vinyl chloride waterproof sheet material containing a flame retardant additive, it has a waterproof function.
(2) Nonflammable metal spraying is applied to the surface of the waterproof sheet material, and a flame retardant is added to the waterproof sheet material itself. There is no problem at all, and of course, there is no ignition, fire spread, or deformation, and it is close to a refractory material that does not ignite even if directly exposed to flame within 20 minutes, and has an excellent fire prevention function.
(3) Since it is covered with a vinyl chloride waterproof sheet material, when it comes into contact with a high temperature flame for a long time, a chlorine-based fire extinguishing gas is generated and the spread of the roof base material can be suppressed.
(4) Although roof materials such as clay tiles are relatively heavy and affect the earthquake resistance of the entire house, they have problems with earthquake resistance, but the fireproof waterproof sheet for roofing of the present invention is lightweight (about 1 of clay tiles). / 20 to 1/15, about 1/10 of a slate tile, and about 1/2 of a colored iron plate, the use of this reduces the weight of the entire roof and provides excellent earthquake resistance.
(5) Clay tiles, slate tiles, and colored iron plates have a problem of waterproofness due to freezing and thawing in cold regions. On the other hand, the fireproof waterproof sheet for roofing of the present invention has overlap joints, and the portion is not metal sprayed and the vinyl chloride sheet is exposed on the surface. Surface welding with overlapping joints is possible, and it can be securely joined and the roof as a whole can be more waterproof and weather resistant.
(6) Also, in the case of the fireproof waterproof sheet for roofing of the present invention, for example, fixing to a roof base material such as a vinyl chloride steel sheet is performed by surface-welding the back side of the fireproof waterproof sheet to this base material, Since it adheres and is securely fixed, the roof as a whole is more waterproof and weatherproof and durable. In this case, the end portion of the fireproof waterproof sheet can be wound around the back side of the roof base and similarly fixed by surface welding, so that the waterproofness is further enhanced.
(7) Clay tiles, slate tiles, colored iron plates, and the like have a problem of flying due to strong winds such as typhoons. On the other hand, in the case of the fireproof waterproof sheet for roofing according to the present invention, as described above, the joint is joined without gaps due to surface welding, and this joining is maintained semi-permanently even with respect to temperature change or water immersion. Because it can be securely fixed to the roof base material, it is not easily affected by strong winds such as typhoons.
(8) In addition, the color iron plate has a problem of rust due to salt damage and noise during wind and rain, but the fireproof waterproof sheet for roofing of the present invention is resistant to rust, and the sound during wind and rain is relatively small.
(9) Since it is a thin sheet shape or plate shape, it is lightweight and has flexibility, so it is rich in workability.
(10) Since the sheet material is made of a vinyl chloride resin having an elongation property and is made into a thin sheet or plate, it is easy to follow the movement of the roof base material, and the roofing work is facilitated.
(11) For example, it is possible to give an uneven finish and the like, which can contribute to the safety of the worker who works on the seat.
(12) Since the surface can be decorated with various patterns and colors to create a unique design, the roof becomes rich in changes when it is struck.
(13) Furthermore, in comparison with a three-layer structure that requires an intermediate layer such as a fireproof and flameproof layer, it is possible to adopt a two-layer structure of a heat insulating material and a waterproof sheet as in the past. In addition, the construction cost is economical, and it is lightweight and can reduce the effects of earthquakes.

本願考案の屋根葺き用防火防水シートの実施形態の一例を図１〜図３に基づいて説明する。図１に示すように、本願考案の屋根葺き用防火防水シート１は、厚さ１．２〜３．０ｍｍ、幅（短手方向の長さ）６００〜１３００ｍｍの板状又はシート状の形状を呈しており、長手方向はロール状に巻かれるなど短手方向に比して長いものにすることができる。なお、屋根葺き用防火防水シート１の厚さが１．２ｍｍ未満の場合、シートの強度不足のため耐久性に問題が残る。例えば、屋根下地コンクリートの打ち継ぎ目や亀裂の影響を受けて、又は屋根下地材としてのＡＬＣ版や鉄板などの継ぎ目の影響を受けて、屋根葺き用防火防水シート１が破損する恐れがある。また、屋根葺き用防火防水シート１の厚さが３．０ｍｍを超える場合、屋根葺き用防火防水シート１の継ぎ手部分が三枚重ねとなる個所は隙間を生じやすく、すなわち水密性が悪くなり、結果的に屋根全体の防水性が劣るという課題がある。   An example of an embodiment of the fireproof waterproof sheet for roofing according to the present invention will be described with reference to FIGS. As shown in FIG. 1, the fireproof waterproof sheet 1 for roofing according to the present invention has a plate-like or sheet-like shape having a thickness of 1.2 to 3.0 mm and a width (length in the short direction) of 600 to 1300 mm. The longitudinal direction can be made longer than the short direction, such as being wound in a roll. In addition, when the thickness of the fireproof waterproof sheet 1 for roofing is less than 1.2 mm, a problem remains in durability due to insufficient strength of the sheet. For example, there is a possibility that the fireproof waterproof sheet 1 for roofing may be damaged due to the influence of seams and cracks in the roof base concrete, or the influence of seams such as ALC plates or iron plates as the roof base material. Moreover, when the thickness of the fireproof waterproof sheet 1 for roofing exceeds 3.0 mm, a portion where the joint portions of the fireproof waterproof sheet 1 for roofing are three-layered easily forms a gap, that is, the water tightness is deteriorated. As a result, there is a problem that the waterproof property of the entire roof is inferior.

本願考案の屋根葺き用防火防水シート１は、図１に示すように、塩化ビニル系の防水シート材料２の肉厚方向略中間部に、耐火性の芯材３が積層配置されている。   As shown in FIG. 1, a fireproof waterproof sheet 1 for roofing according to the present invention has a fireproof core material 3 laminated in a substantially middle portion in the thickness direction of a vinyl chloride waterproof sheet material 2.

塩化ビニル系の防水シート材料２は、塩化ビニル樹脂系の材料に難燃剤を添加配合して作られたものである。この配合は例えば、塩化ビニル樹脂系の材料（通常の可塑剤、安定剤、顔料を含む）１００重量部、炭酸カルシウム４０〜２５０重量部、三酸化アンチモン５〜１０重量部とすることができる。   The vinyl chloride waterproof sheet material 2 is made by adding a flame retardant to a vinyl chloride resin material. This blending can be, for example, 100 parts by weight of a vinyl chloride resin-based material (including ordinary plasticizers, stabilizers and pigments), 40 to 250 parts by weight of calcium carbonate, and 5 to 10 parts by weight of antimony trioxide.

板状又はシート状の防水シート材料２の表面には、不燃性又は、不燃性及び防錆性のある金属粒子４が溶射され、これにより防水シートの表面にこの金属粒子４が溶沈（溶け込む）される。この金属溶射方法は低温溶射でも高温溶射でも可能であり、溶射する金属粒子４に不燃アルミニウムと亜鉛の合金、又はアルミニウムを用いると軽量化を図ることができる。   Non-combustible or non-combustible and rust-proof metal particles 4 are sprayed on the surface of the sheet-like or sheet-like waterproof sheet material 2, whereby the metal particles 4 are deposited (dissolved) on the surface of the waterproof sheet. ) This metal spraying method can be either low-temperature spraying or high-temperature spraying. When the metal particles 4 to be sprayed are made of an incombustible aluminum / zinc alloy or aluminum, the weight can be reduced.

芯材３は屋根葺き用防火防水シート１全体の強度を高めるためのもので、高熱による盛り上がりなどの変形を防ぐことができる。芯材には、変形に対抗しうる強度を有する材料であるガラスクロス又は金属クロスを用いることが望ましいが、これに代えてガラス不織布などを用いることもできる。   The core material 3 is for increasing the strength of the fireproof waterproof sheet 1 for roofing, and can prevent deformation such as swell due to high heat. As the core material, it is desirable to use a glass cloth or a metal cloth which is a material having a strength capable of resisting deformation, but a glass nonwoven fabric or the like can be used instead.

本願考案の屋根葺き用防火防水シート１は、２層の塩化ビニル系の防水シート材料２の間に芯材３を挟んで加熱圧着（ロールプレス等）し、板状又はシート状に加工される。このようにして成形された屋根葺き用防火防水シート１は肉薄・軽量で、柔軟性があり、持ち運びや固定作業などの施工が容易な製品となる。   The fireproof waterproof sheet 1 for roofing according to the present invention is processed into a plate shape or a sheet shape by thermocompression bonding (roll press or the like) with a core material 3 sandwiched between two layers of vinyl chloride waterproof sheet material 2. . The fireproof waterproof sheet 1 for roofing formed in this way is thin and lightweight, flexible, and easy to carry and carry out for fixing work.

図２に示すように、金属粒子４の溶射は、屋根葺き用防火防水シート１の外側表面５のほぼ全体に施されるが、屋根葺き用防火防水シート１どうしの接合部分である重ね継ぎ手しろ６にはこれを溶射しない。重ね継ぎ手しろ６は、図２のように屋根葺き用防火防水シート１の長尺辺１ａとそれに連続する短尺辺１ｂに形成されており、その幅はＷ＝４０〜１００ｍｍとしてある。   As shown in FIG. 2, the thermal spraying of the metal particles 4 is performed on almost the entire outer surface 5 of the roofing fireproof waterproof sheet 1, but the overlap joint which is a joint portion between the roofing fireproof waterproof sheets 1. 6 is not sprayed. The lap joint margin 6 is formed on the long side 1a of the fireproof waterproof sheet 1 for roofing and the short side 1b continuous thereto as shown in FIG. 2, and the width is W = 40 to 100 mm.

屋根葺き用防火防水シート１の外側表面５であって、重ね継ぎ手しろ６を除いた部分には模様が施されている。図２の模様７は横長板（スレート瓦）を千鳥配列に葺いたような形状の模様にしてあるが、模様はそれ以外の幾何学的模様、図案、図形といった各種模様とすることができる。型付けや印刷により種々の模様７を付することが可能で、各種柄や色彩で飾って個性的な意匠とすることができる。   A pattern is applied to the outer surface 5 of the fireproof waterproof sheet 1 for roofing, excluding the overlap joint 6. The pattern 7 in FIG. 2 is a pattern in which a horizontally long plate (slate roof tile) is arranged in a staggered arrangement, but the pattern can be various patterns such as other geometric patterns, designs, and figures. Various patterns 7 can be given by patterning or printing, and can be decorated with various patterns and colors to make unique designs.

屋根葺き用防火防水シート１の表面（屋根に葺いたときの上面）には滑り止め加工、例えば凸凹仕上げ等を施すことが可能で、シート上に乗って施工する作業員の滑落防止など安全に寄与することができる。   The surface of the fireproof waterproof sheet 1 for roofing (upper surface when it hits the roof) can be subjected to anti-slip processing, for example, uneven finish, etc. Can contribute.

本願考案の屋根葺き用防火防水シート１を実際の屋根下地８の上に葺いた例を図３に基づいて説明する。屋根葺き用防火防水シート１は所定寸法の板状又はシート状の場合はそのまま、ロール状にまかれている長尺の場合は必要寸法に切断して使用する。この場合例えば、図３（ａ）のように、塩化ビニル鋼板（鋼板の両面又は片面に塩化ビニル樹脂を塗装又は被覆した鋼板）などの屋根下地８に、屋根葺き用防火防水シート１の周縁を屋根下地８の端に揃えてこれを載せ、屋根葺き用防火防水シート１の裏側面（屋根に葺いたときの下面となる面）の裏側周縁部分９に面溶接（熱溶接又は液溶接）を施し、さらに裏側面のうち前記裏側周縁部分９以外である裏側中央部分１０の範囲に接着剤を塗布して固定する。なおこの場合、前記裏側中央部分１０全体に接着剤を塗布する全体接着と、前記裏側中央部分１０の部分的に接着剤を塗布する部分接着とを選択することができる。
屋根葺き用防火防水シート１どうしは、重ね継ぎ手しろ６（W＝４０〜１００ｍｍ）を重ねて敷き並べ、この重ね継ぎ手しろ６部分に面溶接（熱溶接又は液溶接）を施して接合する。
また、図３（ｂ）（ｃ）のように、屋根葺き用防火防水シート１の周縁を塩化ビニル鋼板などの屋根下地８の裏側まで巻き込んで、防水シート１の裏側周縁部分９に面溶接（熱溶接又は液溶接）を施して屋根下地８に固定することもできる。この場合、より一層防水性が高まる。
このように、屋根葺き用防火防水シートの裏面は塩化ビニル樹脂系であり、下地材も塩化ビニル樹脂系である場合には両者を熱溶接により確実に接合、固定できるので、焼瓦やスレート瓦などの屋根葺き構造に比して台風や突風で飛ばされにくい、といった効果もある。 An example in which the roofing fireproof waterproof sheet 1 of the present invention is placed on an actual roof base 8 will be described with reference to FIG. The fireproof waterproof sheet 1 for roofing is used as it is in the case of a plate or sheet having a predetermined dimension, and is cut to a required dimension in the case of a long length wound in a roll. In this case, for example, as shown in FIG. 3 (a), the periphery of the fireproof waterproof sheet 1 for roofing is attached to a roof base 8 such as a vinyl chloride steel plate (a steel plate coated or coated with vinyl chloride resin on both sides or one side of the steel plate). This is placed in line with the edge of the roof base 8, and surface welding (thermal welding or liquid welding) is performed on the back side peripheral portion 9 of the back side surface of the roofing fireproof waterproof sheet 1 (the surface that becomes the bottom surface when the roof is covered). Further, an adhesive is applied and fixed to the range of the back side central portion 10 other than the back side peripheral edge portion 9 in the back side surface. In this case, it is possible to select either the overall adhesion in which the adhesive is applied to the entire back side central portion 10 or the partial adhesion in which the adhesive is partially applied to the back side central portion 10.
The fireproof waterproof sheets 1 for roofing are overlapped and laid together with a lap joint margin 6 (W = 40 to 100 mm), and the lap joint margin 6 is subjected to surface welding (thermal welding or liquid welding) and joined.
Further, as shown in FIGS. 3B and 3C, the periphery of the fireproof waterproof sheet 1 for roofing is wound up to the back side of the roof base 8 such as a vinyl chloride steel plate, and surface welding is performed on the back side peripheral part 9 of the waterproof sheet 1 ( It can also be fixed to the roof substrate 8 by heat welding or liquid welding. In this case, waterproofness is further enhanced.
In this way, if the back side of the fireproof waterproof sheet for roofing is made of vinyl chloride resin and the base material is also made of vinyl chloride resin, both can be securely joined and fixed by heat welding. Compared to roofing structures such as the above, there is an effect that it is hard to be blown away by typhoons and gusts.

本願考案の屋根葺き用防火防水シート１の外側表面５（屋根に葺いたときの上面となる面）のうち、重ね継ぎ手しろ６以外の部分には、溶射された金属粒子４と模様７が見られる（露出する）。   Of the outer surface 5 of the fireproof waterproof sheet 1 for roofing according to the present invention (the surface which becomes the upper surface when the roof is covered), the sprayed metal particles 4 and the pattern 7 are seen on the portion other than the overlap joint 6. To be exposed.

本願考案の屋根葺き用防火防水シートは、一般家屋や木質住宅にも最適であり、事務所、倉庫又は工場などの建築物の屋根にも利用できるほか、防水機能及び防火機能を併せて必要とするあらゆる場所で利用することができる。例えば、ごみ焼却場や製鉄所など火炎を利用する場所で、飛び火を防ぎたい保護物に本願考案の屋根葺き用防火防水シートを掛けるなど、種々の場所で、種々の利用方法がある。   The fireproof waterproof sheet for roofing of the present invention is suitable for ordinary houses and wooden houses, and can be used for the roofs of buildings such as offices, warehouses, factories, etc. Can be used anywhere. For example, there are various methods of use in various places, such as hanging a fireproof waterproof sheet for roofing of the present invention on a protective object to be prevented from flying in places where flames are used, such as garbage incineration plants and steelworks.
