Description

本発明は、家屋等の屋根構造に関するものであり、特にリフォーム用屋根パネル、該屋根パネルを用いた屋根構造、および屋根リフォーム方法に関するものである。   The present invention relates to a roof structure of a house or the like, and more particularly to a roof panel for renovation, a roof structure using the roof panel, and a roof remodeling method.

従来、屋根パネル等を用いた家屋等の屋根構造は、いくつか提案されている（特許文献１，２参照）。
例えば特許文献１には、胴縁や野地面材をさらにもう一枚必要とすることなく、少ない部材で効率良く屋根の換気を図ることができる屋根パネルを用いた通気性屋根下地構造が開示されている。
また特許文献２には、積層材を用いた断熱欠損部のない屋根構造が開示されている。 Conventionally, several roof structures, such as a house using a roof panel etc., are proposed (refer patent documents 1 and 2).

しかしながら、上記特許文献１，２の構成は新築時に構築する屋根構造しか開示されておらず、近年特に注目されているリフォームには対応できないという問題がある。
また、古くなった瓦を新たに葺き替えるリフォーム方法は既に提供されているものの、リフォーム後の屋根構造は、遮熱性、通気性、および吸音性に劣るという問題がある。
そこで本発明は、遮熱性、通気性、および吸音性に優れたリフォーム用屋根パネル、該屋根パネルを用いた屋根構造、および屋根リフォーム方法を提供することを目的とする。 However, only the roof structure constructed at the time of new construction is disclosed in the configurations of Patent Documents 1 and 2, and there is a problem that it cannot cope with the renovation that has attracted particular attention in recent years.
Moreover, although the renovation method which replaces the old roof tile newly is already provided, there exists a problem that the roof structure after renovation is inferior to heat insulation, air permeability, and sound absorption.
Then, an object of this invention is to provide the roof panel for renovation excellent in heat-insulating property, air permeability, and sound absorption property, the roof structure using the roof panel, and the roof remodeling method.

本発明は、上記課題を解決すべく、垂木上に差し渡された野地面材上に配置するリフォーム用屋根パネルであって、該野地面材上に被着する屋根パネル用野地面材と、該屋根パネル用野地面材の上面に貼着されたプラスチック発泡体からなる断熱板と、該断熱板上面に貼着された、通気路を多数備えるプラスチック製の遮熱板と、からなり、該リフォーム用屋根パネルが野地面材上に配置された際には、該遮熱板の通気路の一端が棟方向に、他端が軒先方向に向けられて該通気路の両端が外気に開放され、かつ該遮熱板の上面側に金属製の屋根材が配置されることを特徴とするリフォーム用屋根パネル（以下、適宜、屋根パネルという）である。   In order to solve the above problems, the present invention is a roof panel for renovation arranged on a field material passed over a rafter, and a field material for a roof panel to be deposited on the field material, A heat insulating plate made of a plastic foam attached to the upper surface of the roof panel field material, and a plastic heat shield plate attached to the upper surface of the heat insulating plate and provided with a large number of air passages, When the roof panel for renovation is arranged on the field material, one end of the heat shield air passage is directed toward the ridge and the other end is directed toward the eaves to open both ends of the air vent to the outside air. In addition, a roof panel for renovation (hereinafter referred to as a roof panel as appropriate) is characterized in that a metal roof material is disposed on the upper surface side of the heat shield plate.

上記発明において、太陽光は屋根材の表面で反射し、該屋根材の輻射熱は該屋根材の下側に配置された遮熱板の表面から放熱される。したがって、該屋根パネルにおいては該反射と該放熱によって太陽光熱を遮熱するため、太陽光熱による室内の温度上昇を防ぐことができる。
該遮熱板に伝わった一部の熱は、該遮熱板の下側に配置された断熱板によって遮断されるため、上記屋根材の輻射熱は室内まで伝わらない。
また、上記遮熱板の通気路により、屋根の厚さを厚くすることなく屋根の通気性を確保することができる。
さらに、上記遮熱板は、多数の通気路によって空気層を具備するため、吸音材として機能して屋根面で鳴る雨音を吸音し、該雨音を室内に伝達させない。かくして、該屋根パネルは吸音性も優れている。 In the said invention, sunlight reflects on the surface of a roofing material, and the radiant heat of this roofing material is thermally radiated from the surface of the heat insulation board arrange | positioned under this roofing material. Therefore, in the roof panel, the solar heat is shielded by the reflection and the heat radiation, so that the indoor temperature rise due to the solar heat can be prevented.
Part of the heat transmitted to the heat shield plate is blocked by the heat insulating plate disposed on the lower side of the heat shield plate, so that the radiant heat of the roof material is not transferred to the room.
In addition, the ventilation path of the heat shield plate can ensure the air permeability of the roof without increasing the thickness of the roof.
Furthermore, since the heat shield plate has an air layer with a large number of air passages, it functions as a sound absorbing material and absorbs rain sound generated on the roof surface and does not transmit the rain sound to the room. Thus, the roof panel is also excellent in sound absorption.

該遮熱板には、ストロー状の通気孔が多数設けられており、該通気孔によって該通気路を構成してもよい。
また、該遮熱板は、波形に成形されており、該波形によって遮熱板の上下両面に形成された溝によって該通気路を構成してもよい。
さらに、一対の遮熱板を備えた構成であって、該遮熱板の表面には多数の突起が設けられており、一方の遮熱板の突起先端を他方の遮熱板の突起が設けられた板面に当接させるように積層し、該一対の遮熱板間に形成される隙間によって通気路を構成してもよい。
上記遮熱板はいずれも多数の通気路が形成されるため、放熱性能に優れている。 The heat shield plate is provided with a number of straw-shaped vent holes, and the vent path may be constituted by the vent holes.
The heat shield plate may be formed into a corrugated shape, and the air passage may be formed by grooves formed on the upper and lower surfaces of the heat shield plate by the corrugated shape.
Furthermore, it is a structure provided with a pair of heat shield plates, and a plurality of protrusions are provided on the surface of the heat shield plate, and the protrusion tips of one heat shield plate are provided with the protrusions of the other heat shield plate. The air passage may be constituted by a gap formed between the pair of heat shield plates so as to be brought into contact with the formed plate surface.
Each of the heat shield plates is excellent in heat dissipation performance because a large number of air passages are formed.

また、本発明は、上記のリフォーム用屋根パネルに配置される該屋根材の上面側に太陽電池を配置したことを特徴とする屋根構造である。このように太陽電池と屋根の断熱通気構造とを組み合わせることで家屋の温熱環境を効率的に制御可能となる。   Moreover, this invention is a roof structure characterized by having arrange | positioned the solar cell on the upper surface side of this roof material arrange | positioned at said roof panel for renovation. Thus, it becomes possible to control the thermal environment of a house efficiently by combining a solar cell and the heat insulation ventilation structure of a roof.

さらに、上記の屋根パネルを用いた屋根リフォーム方法が提案される。すなわち、垂木上に差し渡された野地面材上に配されている屋根材（瓦）を撤去した後、該野地面材の上面に前記リフォーム用屋根パネルを配置し、かつ、該遮熱板の該通気路の一端を棟方向に、他端を軒先方向に向けて該通気路の両端を外気に開放し、該遮熱板の上面側に金属製の屋根材を配置することを特徴とする屋根リフォーム方法である。   Furthermore, a roof reforming method using the above roof panel is proposed. That is, after removing the roofing material (tile) arranged on the field material passed over the rafter, the renovation roof panel is disposed on the upper surface of the field material, and the heat shield plate One end of the air passage is directed to the ridge direction, the other end is directed to the eaves direction, both ends of the air passage are opened to the outside air, and a metal roofing material is disposed on the upper surface side of the heat shield plate. It is a roof remodeling method.

上記方法は、あらかじめ工場等で製造したリフォーム用屋根パネルをプレカット製作し、リフォーム現場において野地面材上に配置し、新たな屋根を葺くことで屋根の断熱リフォームが完了するから、作業性が極めて良く、リフォームにかかる時間とコストを低く抑えることができる。
また、該方法によって提供される屋根構造は、上述のように、遮熱性、通気性、および吸音性を兼ね備えており、快適な室内空間を提供することができる。 In the above method, the renovation roof panel manufactured in advance at a factory or the like is pre-cut, placed on the field ground at the renovation site, and the roof insulation renovation is completed by rolling a new roof. It is extremely good, and the time and cost for renovation can be kept low.
Further, as described above, the roof structure provided by the method combines heat insulation, air permeability, and sound absorption, and can provide a comfortable indoor space.

本発明は、近年特に注目されているリフォームに対応可能であり、しかも、遮熱性、通気性、および吸音性に優れた屋根構造を提供することができる。   INDUSTRIAL APPLICABILITY The present invention can cope with renovation that has attracted particular attention in recent years, and can provide a roof structure that is excellent in heat insulation, breathability, and sound absorption.

〈第一実施例〉
本発明を図１等に示す実施例に従って説明する。
図１に示すように、リフォーム用屋根パネル(1A)（適宜、屋根パネル(1A)という。）は、屋根パネル用野地面材(2)と、該屋根パネル用野地面材(2)の上面に貼着されている断熱板(3)と、該断熱板(3)の上面に貼着されているプラスチック製の遮熱板(5A)とからなる。各断熱板(3)は間隔をおいて配置されている。また、各遮熱板(5A)は、該断熱板(3)と巾及び奥行きの寸法が同じに設定されており、該断熱板(3)の上面に重ねられている。
なお、該断熱板(3)、あるいは遮熱板(5A)を貼着するには、例えば接着剤を使用することができる。 <First Example>
The present invention will be described according to the embodiment shown in FIG.
As shown in FIG. 1, a roof panel for renovation (1A) (referred to as a roof panel (1A) as appropriate) includes a roof panel field material (2) and an upper surface of the roof panel field material (2). And a heat insulating plate (5A) made of plastic attached to the upper surface of the heat insulating plate (3). The heat insulating plates (3) are arranged at intervals. Each heat shield plate (5A) has the same width and depth dimensions as the heat insulating plate (3), and is overlaid on the upper surface of the heat insulating plate (3).
In order to attach the heat insulating plate (3) or the heat insulating plate (5A), for example, an adhesive can be used.

また、該遮熱板(5A)の内部には、両端が開口したストロー状の通気孔が多数設けられており、該通気孔によって通気路(15A)が多数形成されている。   The heat shield plate (5A) is provided with a large number of straw-shaped vent holes open at both ends, and a large number of vent paths (15A) are formed by the vent holes.

前記断熱板(3)は、プラスチック発泡体で構成されている。該プラスチック発泡体としては、例えばポリスチレン発泡体、ポリエチレン発泡体、ポリプロピレン発泡体、半硬質ポリウレタン発泡体、上下両面にプラスチックフィルムが貼着されている半硬質ポリウレタン発泡体あるいはフェノール樹脂発泡体等が好ましい。
また、前記遮熱板(5A)は、発泡スチレンシート（PSP）で構成されている。例えば、上記遮熱板(5A)は、ポリスチレンと発泡剤とを押出発泡させる際に通気路(15A)となる通気孔を多数形成する金型を用いて製造することができる。 The heat insulating plate (3) is made of a plastic foam. As the plastic foam, for example, a polystyrene foam, a polyethylene foam, a polypropylene foam, a semi-rigid polyurethane foam, a semi-rigid polyurethane foam having a plastic film attached on both upper and lower surfaces, or a phenol resin foam is preferable. .
The heat shield plate (5A) is formed of a foamed styrene sheet (PSP). For example, the heat shield plate (5A) can be manufactured using a mold that forms a large number of air holes that serve as air passages (15A) when polystyrene and a foaming agent are extruded and foamed.

次に、上記従来家屋の屋根構造をリフォームする手順を説明する。
図４に示す上記従来家屋の屋根構造(100)をリフォームする場合には、まず、屋根構造(100)における古い屋根材(107)（例えば瓦）や防水シート(106)を撤去する。そして、腐食又は老朽した垂木(102)や野地面材(105)を修繕する。 Next, a procedure for reforming the roof structure of the conventional house will be described.
When reforming the roof structure (100) of the conventional house shown in FIG. 4, first, the old roof material (107) (for example, tiles) and the waterproof sheet (106) in the roof structure (100) are removed. Then, the corrugated or old rafter (102) and the field material (105) are repaired.

次に、図２に示すように、修繕後の該野地面材(105)上に、図１に示す屋根パネル(1A)を配置する。具体的には、屋根パネル用野地面材(2)を該野地面材(105)上に被着すると共に、該遮熱板(5A)の通気路(15A)の上端（一端）を棟換気部材（図示省略）に接続して外気に連通し、かつ該通気路(15A)の下端（他端）を軒先換気部材（図示省略）に接続して外気に連通する。   Next, as shown in FIG. 2, the roof panel (1A) shown in FIG. 1 is placed on the field material (105) after the repair. Specifically, the roof panel field material (2) is deposited on the field material (105), and the upper end (one end) of the ventilation path (15A) of the heat shield (5A) is ridge ventilation. A member (not shown) is connected to communicate with the outside air, and a lower end (the other end) of the ventilation path (15A) is connected to an eaves tip ventilation member (not shown) to communicate with the outside air.

更に、断熱板(3)間の間隙(4)に新規の垂木(7A)を介挿し、釘(6)などの固定手段で既設の垂木(102)に固定する。   Further, a new rafter (7A) is inserted into the gap (4) between the heat insulating plates (3), and fixed to the existing rafter (102) by a fixing means such as a nail (6).

そして、該遮熱板(5A)と垂木(7A)の上面に防水シート(8)を敷いてから、例えばアルミニウム製の屋根材(9A)を新しく葺くことにより、屋根のリフォームが完了する。   Then, after the waterproof sheet (8) is laid on the top surfaces of the heat shield (5A) and the rafter (7A), the roof renovation is completed by newly spreading, for example, an aluminum roofing material (9A).

上記リフォーム後の屋根構造(10A)は、工場でプレカットした屋根パネル(1A)を現場で野地面材(105)上に設置し、その上から新規の垂木(7A)を既設の垂木(102)に固定し、新たに屋根材(9A)を葺くだけで構築できるため、簡便で低コストである。   The roof structure (10A) after the above renovation is to install the roof panel (1A) pre-cut at the factory on the field ground material (105), and then add a new rafter (7A) from the existing rafter (102). It is simple and low-cost because it can be constructed simply by sowing the roof material (9A).

また、反射性の高い金属製の該屋根材(9A)は、太陽光を反射して室内の温度上昇を抑制するが、該屋根材(9A)には輻射熱が蓄えられる。このとき本実施例の屋根構造(10A)においては、該屋根材(9A)の下に配された遮熱板(5A)の通気路(15A)を空気が流動して該輻射熱を放熱するため、該遮熱板(5A)が放熱層を構成して屋根構造(10A)の遮熱効果を向上せしめ、室内の温度上昇を抑制する。ここで仮に該屋根材(9A)の下に放熱層がないと、該屋根材(9A)の輻射熱が下側の断熱材(3)に伝導してしまって該断熱板(3)が熱せられ、室内の温度上昇を招いてしまうことになる。   Further, the roof material (9A) made of metal having high reflectivity reflects sunlight and suppresses the temperature rise in the room, but radiant heat is stored in the roof material (9A). At this time, in the roof structure (10A) of the present embodiment, the air flows through the ventilation path (15A) of the heat shield plate (5A) disposed under the roof material (9A) to radiate the radiant heat. The heat shield plate (5A) constitutes a heat dissipation layer to improve the heat shield effect of the roof structure (10A) and suppress the temperature rise in the room. Here, if there is no heat dissipation layer under the roofing material (9A), the radiant heat of the roofing material (9A) is conducted to the lower heat insulating material (3) and the heat insulating plate (3) is heated. The indoor temperature will be increased.

さらに、本実施例の屋根構造(10A)においては、上記遮熱板(5A)の下に断熱板(3)を配置しているため、上記屋根材(9A)から該遮熱板(5A)に伝わった熱は、該断熱板(3)によって遮られて室内まで伝わらない。
したがって、該屋根パネル(1A)は、太陽光熱を好適に遮熱して室内の温度上昇を確実に防止する。 Further, in the roof structure (10A) of the present embodiment, since the heat insulating plate (3) is disposed under the heat shield plate (5A), the heat shield plate (5A) is separated from the roof material (9A). The heat transmitted to is blocked by the heat insulating plate (3) and is not transmitted to the room.
Therefore, the roof panel (1A) suitably shields solar heat and reliably prevents an increase in indoor temperature.

さらに、該遮熱板(5A)の通気路(15A)は外気に開放されて通気自在であるため、屋根の通気性が確保され、例えば断熱板(3)に結露が生じない。さらに加えて、該遮熱板(5A)は、多数の通気路(15A)によって空気層を具備するため、吸音材として機能し、屋根面で鳴る雨音を吸音して室内に伝達させない。したがって、該屋根パネル(1A)は、遮熱性、通気性、および吸音性に優れている。
また、上記材料からなる遮熱板(5A)は、剛性が高く、リフォーム作業時に作業員等が乗っても潰れずに形体が保持されるため、該通気路(15A)が閉塞してしまうことがない。 Further, since the air passage (15A) of the heat shield plate (5A) is open to the outside air and can be freely ventilated, the air permeability of the roof is ensured, for example, no condensation occurs on the heat insulating plate (3). In addition, since the heat shield plate (5A) includes an air layer by a large number of air passages (15A), it functions as a sound absorbing material and does not absorb rain sound generated on the roof surface and transmit it to the room. Therefore, the roof panel (1A) is excellent in heat insulation, air permeability, and sound absorption.
Further, the heat shield plate (5A) made of the above material has high rigidity, and the shape is held without being crushed even if a worker or the like gets on during the renovation work, so that the air passage (15A) is blocked. There is no.

〈第二実施例〉
図３に従って、第二実施例の屋根構造(10B)を説明する。
本実施例では、屋根パネル(1A)を配置する場合に、断熱板(3)間の間隙(4)に垂木(7B)を介挿して固定する。該垂木(7B)の上端高さは、前記遮熱板(5A)の上面高さよりも高位に設定される。 <Second Example>
The roof structure (10B) of the second embodiment will be described with reference to FIG.
In the present embodiment, when the roof panel (1A) is arranged, the rafter (7B) is interposed and fixed in the gap (4) between the heat insulating plates (3). The upper end height of the rafter (7B) is set higher than the upper surface height of the heat shield plate (5A).

そして、該垂木(7B)と該遮熱板(5A)の各上面に、例えばアルミニウム製の屋根材(9B)を瓦棒(19)が垂木(7B)上に位置するように瓦棒式に葺く。さらに上記屋根材(9B)上には、太陽電池(20)を配置することができる。   Then, on each upper surface of the rafter (7B) and the heat shield (5A), for example, an aluminum roofing material (9B) is tiled so that the tile rod (19) is positioned on the rafter (7B). Ask. Furthermore, a solar cell (20) can be disposed on the roof material (9B).

〈変形例〉
図５に示すように、これまでに述べた遮熱板(5A)に代えて、波形に成形された遮熱板(5B)を採用してもよい。
該遮熱板(5B)は、その凹凸によって表面に多数の溝が形成されている。
具体的に該屋根構造(10C)は、図６に示すように、屋根パネル(1B)を野地面材(105)上に配置した状態で、該遮熱板(5B)の上側の防水シート(8)と下側の断熱板(3)とで通気路(15B)が構成され、該通気路(15B)の上端を棟換気部材（図示省略）に接続し、下端を軒先換気部材（図示省略）に接続して通気を確保する。 <Modification>
As shown in FIG. 5, instead of the heat shield plate (5A) described so far, a heat shield plate (5B) formed into a corrugated shape may be employed.
The heat shield plate (5B) has a number of grooves formed on its surface due to the unevenness.
Specifically, as shown in FIG. 6, the roof structure (10C) includes a waterproof sheet (5B) on the upper side of the heat shield plate (5B) in a state where the roof panel (1B) is disposed on the field ground material (105). 8) and the lower heat insulating plate (3) form an air passage (15B), the upper end of the air passage (15B) is connected to the building ventilation member (not shown), and the lower end is connected to the eaves ventilation member (not shown) ) To ensure ventilation.

また、図７に示すような、表面に複数の突起(5D)が形成された遮熱板(5C)を採用してもよい。さらに詳しく述べれば、屋根パネル(1A,1B)に使用する場合には、一対の該遮熱板(5C,5C)を準備し、一方の遮熱板(5C)の突起(5D)の先端を他方の遮熱板(5C)の板面に当接させるように積層し、該一対の該遮熱板(5C,5C)を断熱板(3)上面に配置する。このような構成では、複数の突起(5D)間の隙間が通気路(15C)となる。   Further, a heat shield plate (5C) having a plurality of protrusions (5D) formed on the surface as shown in FIG. 7 may be employed. More specifically, when using it for a roof panel (1A, 1B), prepare a pair of the heat shield plates (5C, 5C), and attach the tip of the projection (5D) of one of the heat shield plates (5C). The heat shield plates (5C) are stacked so as to contact each other, and the pair of heat shield plates (5C, 5C) are arranged on the upper surface of the heat insulating plate (3). In such a configuration, a gap between the plurality of protrusions (5D) serves as a ventilation path (15C).

本発明は、これまでに述べた実施例に限定されない。例えば、屋根材(9A,9B)としては、ステンレスやガルバリウムなどの他の金属製の屋根材であってもよい。また、上記屋根パネル(1A,1B)は、寄棟、分岐屋根の頂上、隅部、谷部においても適用可能である。   The invention is not limited to the embodiments described so far. For example, the roof material (9A, 9B) may be a roof material made of another metal such as stainless steel or galvalume. Moreover, the said roof panel (1A, 1B) is applicable also in a dormitory, the top of a branched roof, a corner, and a trough.

本発明は、屋根の遮熱性、通気性、および吸音性を兼ね備えた屋根構造、および屋根のリフォーム方法であり、産業上利用可能である。   INDUSTRIAL APPLICABILITY The present invention is a roof structure that combines heat insulation, air permeability, and sound absorption of a roof, and a roof remodeling method, and is industrially applicable.
