Abstract

PROBLEM TO BE SOLVED: To provide a heat-insulation method of an existing roof, which exerts a heat insulation effect without changing a shape of the existing roof, increases durability and also contributes to snow measures.SOLUTION: The heat-insulation method of the existing roof achieves the heat insulation effect without changing the shape of the existing roof, increases durability of the roof and also contributes to snow measures by partially bonding a heat-insulation waterproof member to the existing roof, which comprises: a heat insulation plate made of an expanded polystyrene foam; an urethane rubber-based waterproof material laminated on the heat insulation plate; and further a top coat that is applied on the waterproof material and has a color similar to the existing roof.

Description

本発明は既存の戸建住宅の屋根、例えばトタン屋根あるいは瓦屋根等の形状を替えることなく断熱工事を可能にする既存屋根の断熱工法に係り、特に、この断熱工事を採用することによって屋根の断熱に加えて屋根の耐久性を増すのみならず、雪対策にも貢献できる既存屋根の断熱工法に関する。   The present invention relates to a heat insulation method for an existing roof that enables heat insulation work without changing the shape of an existing detached house roof, such as a tin roof or a tile roof, and in particular, by adopting this heat insulation work, The present invention relates to a heat insulation method for an existing roof that not only increases the durability of the roof in addition to the heat insulation but also contributes to snow measures.

戸建住宅において、寒冷地の断熱工事のみならず、温暖地の断熱工事も極めて重要な工事である。例えば、壁の断熱が無い場合、同様、約３０〜３５％の防熱、防寒比率が低下する。また、屋根の断熱が無い場合も同様、約３０〜３５％の防熱、防寒比率が低下すると云われている。   In a detached house, not only the heat insulation work in cold regions but also the heat insulation work in warm regions is extremely important. For example, when there is no heat insulation of the wall, the heat and cold protection ratio is reduced by about 30 to 35%. Similarly, when there is no heat insulation of the roof, it is said that the heat and cold protection ratio is reduced by about 30 to 35%.

一般住宅等の建物に対する断熱施工は通常、新築工事の際に外壁内に断熱材を挿入することにより行われるが、北海道等の寒冷地では既存の建物への断熱施工が強く望まれている。   Insulation work for buildings such as ordinary houses is usually performed by inserting a heat insulating material into the outer wall at the time of new construction work. In cold regions such as Hokkaido, heat insulation work for existing buildings is strongly desired.

既存の建物への断熱施工として、従来、特公平６―９９８号公報に記載される施工技術が知られている。   Conventionally, the construction technique described in Japanese Patent Publication No. 6-998 is known as a heat insulation construction for an existing building.

この技術は同公報特許請求の範囲に記載されるように、既存建物の外壁面に発泡体ボードを張りつけ、その上にさらにモルタル仕上げ材を塗布することを特徴とし、前記発泡体ボードは主成分としての炭酸カルシウム粉末と、補強材としての無機質繊維材料と、結合材とから構成され、前記モルタル仕上げ材は前記発泡体ボードの粉末とセメントとから構成されてなることに存する。   As described in the claims of this publication, this technology is characterized in that a foam board is attached to the outer wall surface of an existing building, and a mortar finish is further applied thereon, and the foam board is a main component. The calcium carbonate powder as a reinforcing material, an inorganic fiber material as a reinforcing material, and a binder, and the mortar finish is composed of the foam board powder and cement.

しかし、この公知工法は既存建物の屋根面ではなく、外壁面を対象とする工法であって、トタン屋根や瓦屋根の形状を替えることなく断熱工事を可能にするものではなく、ましてや屋根の耐久性を増すものではなく、雪対策にも貢献するものではない。   However, this well-known construction method is not for the roof surface of existing buildings but for the outer wall surface, and it does not enable insulation work without changing the shape of the tin roof or tile roof. It does not increase the nature and does not contribute to snow measures.

特公平６−９９８号公報Japanese Patent Publication No. 6-998

本発明が解決しようとする課題は既存の戸建住宅のトタン屋根あるいは瓦屋根等の形状を替えることなく断熱工事を可能にするのみならず、屋根の耐久性を増すとともに、雪対策にも貢献でき、上述の公知技術に存する欠点を改良した既存屋根の断熱工法を提供することにある。   The problem to be solved by the present invention is not only to enable insulation work without changing the shape of the tin roof or tile roof of the existing detached house, but also to increase the durability of the roof and contribute to snow measures An object of the present invention is to provide a heat insulation method for an existing roof that improves the above-mentioned drawbacks of the known technology.

前述の課題を解決するため、本発明の既存屋根の断熱工法によれば、発泡ポリスチレンブロックの断熱板と、その上に積層されたウレタンゴム系の防水材と、さらにその上に塗布された既存の屋根と同様な色彩のトップコートとからなる断熱防水部材を既存の屋根に部分的に接着することを特徴とする。   In order to solve the above-mentioned problems, according to the heat insulation method for an existing roof of the present invention, a heat insulating plate of a polystyrene foam block, a urethane rubber waterproof material laminated thereon, and an existing coating applied thereon A heat insulating waterproofing member comprising a top coat of the same color as that of the roof is partially bonded to the existing roof.

上述の本発明は発泡ポリスチレンブロックの断熱板と、その上に積層されたウレタンゴム系の防水材と、さらにその上に塗布された既存の屋根と同様な色彩のトップコートからなる断熱防水部材を既存の屋根に部分的に接着するようにしたから、屋根の断熱効果はもちろんのこと、屋根の耐久性が増すとともに雪対策にも貢献できる。   The above-mentioned present invention comprises a heat insulating waterproof member comprising a foamed polystyrene block heat insulating plate, a urethane rubber waterproof material laminated thereon, and a top coat of the same color as an existing roof applied thereon. Since it is partially bonded to the existing roof, not only the heat insulation effect of the roof but also the durability of the roof is increased and it can contribute to snow countermeasures.

図１は戸建住宅の屋根部分の一般例であって、屋根の断熱が必要なことを示す。（実施例）FIG. 1 is a general example of a roof portion of a detached house, and shows that the heat insulation of the roof is necessary. (Example) 図２は本発明に使用される断熱防水部材の断面図である。（実施例）FIG. 2 is a cross-sectional view of a heat insulating waterproof member used in the present invention. (Example) 図３は瓦屋根の一般例であって、本発明の断熱防水部材を適用する前の施行前図面である。（実施例）FIG. 3 is a general example of a tile roof, and is a drawing before enforcement before applying the heat insulating waterproofing member of the present invention. (Example) 図４は本発明にかかる断熱防水部材を適用後の施行後図面である。（実施例）FIG. 4 is a view after enforcement after application of the heat insulating waterproofing member according to the present invention. (Example)

以下、本発明を前述の図１〜図４を用い、実施例により、具体的に詳述する。   Hereinafter, the present invention will be described in detail by way of examples with reference to FIGS.

図１は戸建住宅の屋根部分の一般例であって、図１中Ａは屋根であり、例えばトタン屋根、瓦敷き屋根等でつくられている。このような屋根では約３０〜３５％防熱防寒比率が低下する。   FIG. 1 is a general example of a roof portion of a detached house, and A in FIG. 1 is a roof, which is made of a tin roof, a tiled roof, or the like. In such a roof, the heat and cold protection ratio is reduced by about 30 to 35%.

図２は図１の屋根に適用される断熱防水部材Ｂの一具体例の断面図であって、発泡ポリスチレンブロックの断熱板２と、その上に積層されたウレタンゴム系の防水材３と、さらにその上に塗布された既存の屋根Ａと同様な色彩のトップコート４とから構成される。この断熱防水部材Ｂの大きさは任意であるが、例えば幅９００ｍｍ、奥行９１０ｍｍ、厚さ５０ｍｍである。   FIG. 2 is a cross-sectional view of a specific example of a heat insulating waterproofing member B applied to the roof of FIG. 1, a heat insulating plate 2 of a foamed polystyrene block, and a urethane rubber waterproofing material 3 laminated thereon, Furthermore, it is comprised from the topcoat 4 of the color similar to the existing roof A apply | coated on it. The size of the heat insulating waterproofing member B is arbitrary, but is, for example, 900 mm wide, 910 mm deep, and 50 mm thick.

発泡ポリスチレンブロックの断熱板２は例えば図３の瓦敷き屋根１に合わせて成形される。そして、この上に図４に示されるように、ウレタンゴム系の防水材３を積層する。この積層は主剤としてＡ液Ｏ＝Ｃ＝Ｎ〜〜〜（主）〜〜〜Ｎ＝Ｃ＝Ｏと、硬化剤としてＢ液ＨＯ（硬）−ＯＨ（ポリオール）またはＮＨ２−（硬）−ＮＨ２（ポリアミン）をマシンで混合し、発泡ポリスチレンブロックの断熱板２上に吹きつけることにより行われ、ウレタンゴム系の防水材３が形成される。このウレタンゴム系の防水材３上にトップコート４を塗布することにより本発明にかかる断熱防水部材Ｂを形成する。 The heat insulating plate 2 of a foamed polystyrene block is formed, for example, according to the tiled roof 1 of FIG. Then, as shown in FIG. 4, a urethane rubber waterproof material 3 is laminated thereon. The lamination A solution O = C = N~~~ as main agent (main) ～～～N = and C = O, B liquid HO (hardness) as a curing agent -OH (polyols) or NH 2 - (hard) - NH 2 (polyamine) is mixed by a machine and sprayed onto a heat insulating plate 2 of a foamed polystyrene block to form a urethane rubber waterproof material 3. The heat insulating waterproofing member B according to the present invention is formed by applying a top coat 4 on the urethane rubber waterproofing material 3.

本発明は上述のように形成された断熱防水部材Ｂを、例えば図３中、１で示される瓦敷き屋根に接着剤で部分的に接着し、図４で示すように既存屋根の断熱工程を完了する。   In the present invention, the heat insulating waterproofing member B formed as described above is partially bonded with an adhesive to a tiled roof indicated by 1 in FIG. 3, for example, and the heat insulating process of the existing roof as shown in FIG. Complete.

このような本発明工法は屋根の断熱はもちろんのこと、屋根の瓦を本発明の断熱防水部材Ｂで覆うので屋根の耐久性を増す。さらにウレタンゴム系防水材３は雪をつもりにくくし、滑らすので雪対策にも貢献できる。 Such a construction method of the present invention increases the durability of the roof because the roof tile is covered with the heat insulating waterproofing member B of the present invention as well as the heat insulation of the roof. Furthermore, the urethane rubber waterproofing material 3 makes it difficult to snow and slides, so it can contribute to snow countermeasures.

本発明は断熱防水部材Ｂを既存の屋根に張るので、寒冷地のみならず、温暖地にも適用でき、さらに寒冷地ではウレタンゴム系防水材３は雪を滑らすので雪対策にもなり、産業上の利用可能性は高い。   Since the heat insulating waterproofing member B is stretched over the existing roof, the present invention can be applied not only in cold regions but also in warm regions. Further, in the cold regions, the urethane rubber waterproofing material 3 slides on snow, which is also a countermeasure against snow. The above availability is high.
