Description

本発明は、陸屋根部とその端縁から下向きに形成される傾斜屋根部とを備えた屋根構造、及びそれを備えた建物に関するものである。   The present invention relates to a roof structure including a land roof portion and an inclined roof portion formed downward from an edge thereof, and a building including the same.
折板屋根材や屋根パネルを使って平面状の陸屋根部を形成し、その陸屋根部の端縁から下り勾配の傾斜屋根部が形成される屋根構造が知られている(特許文献1−3参照)。   There is known a roof structure in which a flat land roof portion is formed using a folded plate roof material or a roof panel, and an inclined roof portion having a downward slope is formed from an edge of the land roof portion (see Patent Documents 1-3). ).
このような屋根構造には、陸屋根部と傾斜屋根部との境界が発生するため、この不連続となる境界部分の防水処理及び外観処理をどのようにおこなうかという問題がある。   In such a roof structure, since a boundary between the land roof portion and the inclined roof portion is generated, there is a problem of how to perform waterproof treatment and appearance treatment of the discontinuous boundary portion.
例えば、特許文献1の陸屋根部は、凸部が比較的大きくなる折板屋根材によって形成されているため、陸屋根部と傾斜屋根部との境界に背の高い破風化粧板(パラペット)を配置して折板屋根材の端縁を覆い隠すような外観に仕上げている。   For example, since the flat roof part of patent document 1 is formed with the folded-plate roof material from which a convex part becomes comparatively large, the tall windbreak decorative board (parapet) is arrange | positioned on the boundary of a flat roof part and an inclined roof part. The appearance is such that the edge of the folded roof material is covered.
また、特許文献2には、屋根パネルの端部にパネルの半分の厚さの凸部を設け、隣り合う屋根パネルの凸部どうしを上下に重ね合わせることによって防水処理をおこなう構造が開示されている。   Further, Patent Document 2 discloses a structure in which a waterproof treatment is performed by providing a convex portion having a half thickness of the panel at the end of the roof panel and overlapping the convex portions of adjacent roof panels vertically. Yes.
さらに、特許文献3には、陸屋根部と傾斜屋根部との境界にパラペットを設けない外観であって、陸屋根部と傾斜屋根部の境界に沿って樋を設ける構造が開示されている。   Further, Patent Document 3 discloses a structure in which a parapet is not provided at the boundary between the land roof portion and the inclined roof portion, and a fence is provided along the boundary between the land roof portion and the inclined roof portion.

しかしながら、陸屋根部と傾斜屋根部との境界に背の高いパラペットが配置されると、パラペットの存在感が大きくなるため、屋根全体の一体感に欠ける外観になる。一方、陸屋根部と傾斜屋根部との境界における防水処理は、簡単な構造で防水性能の高いものが望まれる。   However, if a tall parapet is arranged at the boundary between the land roof portion and the inclined roof portion, the presence of the parapet increases, so that the entire roof lacks a sense of unity. On the other hand, the waterproof treatment at the boundary between the land roof portion and the inclined roof portion is desired to have a simple structure and high waterproof performance.
そこで、本発明は、陸屋根部と傾斜屋根部とが一体感のある外観となるうえに防水性能に優れた屋根構造、及びそれを備えた建物を提供することを目的としている。   Therefore, an object of the present invention is to provide a roof structure excellent in waterproof performance as well as a building having the waterproof structure as well as a land roof portion and an inclined roof portion having an integrated appearance.
前記目的を達成するために、本発明の屋根構造は、陸屋根部とその端縁から下向きに形成される傾斜屋根部とを備えた屋根構造であって、前記陸屋根部の端縁は前記傾斜屋根部側に庇状に突出されるとともに、前記端縁を覆う軒先カバーが設けられ、前記軒先カバーと前記傾斜屋根部の上縁との間に水切り材が配置されることを特徴とする。   In order to achieve the above object, the roof structure of the present invention is a roof structure including a land roof portion and an inclined roof portion formed downward from the end edge thereof, and the end edge of the land roof portion is the inclined roof portion. An eaves tip cover that protrudes in a bowl shape on the part side and covers the end edge is provided, and a draining material is disposed between the eaves tip cover and the upper edge of the inclined roof portion.
また、本発明の別の屋根構造は、陸屋根部とその端縁から下向きに形成される傾斜屋根部とを備えた屋根構造であって、前記陸屋根部の端縁から前記傾斜屋根部の上縁までを連続して覆う水切り材が配置されることを特徴とする。   Further, another roof structure of the present invention is a roof structure provided with a land roof portion and an inclined roof portion formed downward from the end edge thereof, the upper edge of the inclined roof portion from the end edge of the land roof portion. A draining material that continuously covers up to is arranged.
ここで、前記陸屋根部は、平面状に敷設される下地板と、その下地板の上に設置される両縁に壁部が形成された複数の防水面板と、隣接する前記防水面板の壁部どうしを上から覆う目地カバーとを備えた構成とすることができる。   Here, the flat roof portion is a base plate laid in a planar shape, a plurality of waterproof face plates formed on both edges installed on the base plate, and a wall portion of the adjacent waterproof face plate It can be set as the structure provided with the joint cover which covers each other from the top.
また、前記軒先カバーは上縁部が前記陸屋根部の端縁の上面に固定されるとともに下縁部は前記傾斜屋根部の上面から離隔した状態で配置され、前記水切り材は上縁部が前記陸屋根部の庇状に突出された下面に固定されるとともに表面に前記軒先カバーの下縁部が接続される構成にすることもできる。   Further, the eaves tip cover is arranged with the upper edge portion fixed to the upper surface of the end edge of the flat roof portion and the lower edge portion is separated from the upper surface of the inclined roof portion, and the draining material has the upper edge portion of the upper edge portion. It is also possible to adopt a configuration in which the lower edge portion of the eaves edge cover is connected to the surface while being fixed to the lower surface of the flat roof portion protruding in a bowl shape.
さらに、前記陸屋根部と前記傾斜屋根部との境界上の端部には、前記陸屋根部のパラペット部と前記傾斜屋根部のケラバ部とを繋ぐ化粧部材が設置される構成とすることができる。   Furthermore, it can be set as the structure by which the decorative member which connects the parapet part of the said land roof part and the keraba part of the said inclined roof part is installed in the edge part on the boundary of the said land roof part and the said inclined roof part.
また、前記化粧部材には、前記ケラバ部の化粧カバーの上端と接続させる接続金具が設けられていてもよい。さらに、前記化粧部材には、前記パラペット部の内側面に沿うように延設される垂下壁と、その垂下壁に略直交して屋根内側に向けて延設される重ね片部とが設けられ、前記重ね片部の下方には圧縮されたシーリング材が介在される構成であってもよい。   Further, the decorative member may be provided with a connection fitting that is connected to an upper end of the decorative cover of the keraba portion. Furthermore, the decorative member is provided with a hanging wall that extends along the inner surface of the parapet portion, and an overlapping piece portion that extends substantially perpendicular to the hanging wall toward the inside of the roof.

このため、陸屋根部と傾斜屋根部とが連続しているような外観が創出される。また、軒先カバーと水切り材とによって二重の防水処理がなされるので、陸屋根部と傾斜屋根部との境界を優れた防水性能にすることができる。   For this reason, the external appearance that a land roof part and an inclined roof part continue is created. In addition, since the double waterproof treatment is performed by the eaves edge cover and the draining material, the boundary between the land roof portion and the inclined roof portion can be made excellent waterproof performance.
さらに、陸屋根部の端縁から傾斜屋根部の上縁までを連続して覆う水切り材を配置すれば、陸屋根部と傾斜屋根部との境界において高い防水性能を確保することができる。   Furthermore, if the draining material which covers continuously from the edge of a land roof part to the upper edge of an inclined roof part is arrange | positioned, high waterproof performance can be ensured in the boundary of a land roof part and an inclined roof part.
また、陸屋根部を防水面板によって形成する場合は、折板屋根材を使用する場合に比べて上方への突出量を抑えることができるので、境界に高いパラペットを設けなくても、地上からの外観における陸屋根部の端縁の露出を防ぐことができる。   In addition, when the flat roof part is formed of a waterproof face plate, the amount of upward protrusion can be suppressed compared to the case of using folded plate roofing material, so even if a high parapet is not provided at the boundary, the appearance from the ground It is possible to prevent the exposure of the edge of the land roof portion at.
さらに、軒先カバーを張り出させ、その下縁部と水切り材の表面とを接続する構成であれば、軒先カバーから水切り材に連続して水が流れる構造となって、陸屋根部と傾斜屋根部との接合部における漏水を抑えることができる。   Furthermore, if the eaves end cover is extended and the lower edge portion and the surface of the draining material are connected, the water flows continuously from the eaves end cover to the draining material. It is possible to suppress water leakage at the joint portion.
また、陸屋根部と傾斜屋根部との境界上の端部に、陸屋根部のパラペット部及び傾斜屋根部のケラバ部に繋がる化粧部材が設置される構成であれば、屋根のコーナー部においても一体感のある外観を創出することができる。   Moreover, if the decorative member connected to the parapet part of the flat roof part and the keraba part of the inclined roof part is installed at the end on the boundary between the flat roof part and the inclined roof part, a sense of unity is also felt at the corner of the roof. A certain appearance can be created.
さらに、屋根のコーナー部に設置される化粧部材にケラバ部の化粧カバーの上端を接続可能な接続金具が設けられていれば、化粧部材と傾斜屋根部のケラバ部とが連続した外観を容易に形成することができる。   Furthermore, if the decorative member installed at the corner portion of the roof is provided with a connection fitting that can connect the upper end of the decorative cover of the keraba portion, the appearance that the decorative member and the keraba portion of the inclined roof portion are continuous can be easily obtained. Can be formed.

以下、本発明の実施の形態について図面を参照して説明する。図1は、本実施の形態の屋根10における陸屋根部11と傾斜屋根部12との境界の構成を説明する断面図である。この屋根10は、図2に示すような建物としてのユニット建物1に設けられる。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view illustrating a configuration of a boundary between a land roof portion 11 and an inclined roof portion 12 in a roof 10 according to the present embodiment. This roof 10 is provided in the unit building 1 as a building as shown in FIG.
まず、図2を参照しながらユニット建物1の構成から説明すると、このようなユニット建物1は、工場で製作される複数の建物ユニット及び屋根ユニットを現地で連結することによって構築される。   First, the structure of the unit building 1 will be described with reference to FIG. 2. Such a unit building 1 is constructed by connecting a plurality of building units and a roof unit manufactured in a factory on site.
このユニット建物1は、屋根10の大部分が平坦な陸屋根部11となっており、長方形の短辺側となる妻側に傾斜屋根部12が設けられる。以下では、陸屋根部11の端縁111と傾斜屋根部12の上縁121とが交わる境界を接合部13と呼ぶ。   The unit building 1 has a flat land roof portion 11 in which a majority of the roof 10 is flat, and an inclined roof portion 12 is provided on the wife side that is the short side of the rectangle. Hereinafter, a boundary where the end edge 111 of the land roof portion 11 and the upper edge 121 of the inclined roof portion 12 intersect is referred to as a joint portion 13.
この陸屋根部11は、図3に示すように平面状に敷設される下地板21と、その下地板21の上に設置される両縁に壁部231,231が形成された複数の防水面板としての溝板23と、隣接する溝板23,23の壁部231,231どうしを上から覆う目地カバー24とを主に備えている。   As shown in FIG. 3, the flat roof portion 11 includes a base plate 21 laid flat and a plurality of waterproof face plates in which walls 231 and 231 are formed on both edges installed on the base plate 21. And a joint cover 24 that covers the wall portions 231 and 231 of the adjacent groove plates 23 and 23 from above.
この溝板23は、ステンレス鋼板、アルミメッキ鋼板又は塩化ビニル樹脂被覆銅板などの薄い金属板によって帯状又は長方形状に成形される。そして、金属板の両側の側縁を上方に向けて折り曲げ加工した部分が壁部231,231となる。   The groove plate 23 is formed into a strip shape or a rectangular shape using a thin metal plate such as a stainless steel plate, an aluminized steel plate, or a vinyl chloride resin-coated copper plate. And the part which bent the side edge of the both sides of a metal plate toward the upper direction becomes wall part 231,231.
この溝板23は、下地板21の上に敷設されたルーフィング22の上に隙間なく並べられる。また、一方の溝板23の壁部231と、それに隣接して配置される他方の溝板23の壁部231との間には、図3に示すように断面視略U字形のアンカークリップ25が挿入される。   The groove plates 23 are arranged without gaps on the roofing 22 laid on the base plate 21. Further, between the wall portion 231 of one groove plate 23 and the wall portion 231 of the other groove plate 23 disposed adjacent thereto, as shown in FIG. Is inserted.
このアンカークリップ25は、溝板23と同様の金属板によって成形される。アンカークリップ25は、ルーフィング22上に設置される底部25cと、その両側縁を折り曲げ加工することによって形成されるフランジ25a,25aとを備えている。   The anchor clip 25 is formed of a metal plate similar to the groove plate 23. The anchor clip 25 includes a bottom portion 25c installed on the roofing 22 and flanges 25a and 25a formed by bending both side edges thereof.
また、アンカークリップ25の底部25cには、複数のビス孔25b,・・・が穿孔されており、ビス孔25b,・・・に挿入されるビス(図示省略)によって下地板21にアンカークリップ25が固定される。   Further, a plurality of screw holes 25b,... Are drilled in the bottom portion 25c of the anchor clip 25, and the anchor clip 25 is attached to the base plate 21 by screws (not shown) inserted into the screw holes 25b,. Is fixed.
そして、このアンカークリップ25のフランジ25a,25aによって、隣接して配置される溝板23,23の壁部231,231の移動が規制されることになる。   And the movement of the wall parts 231 and 231 of the groove plates 23 and 23 arrange | positioned adjacently by the flanges 25a and 25a of this anchor clip 25 is controlled.
一方、壁部231,231とアンカークリップ25とによって形成される溝板23,23間の目地は、両側にスカート部24a,24aを備えた断面視略Ω状の目地カバー24によって上から覆われる。目地カバー24の内空には、合成ゴムなどによって形成される底面に粘着層26aが設けられた防水材26が収容される。   On the other hand, the joint between the groove plates 23 and 23 formed by the wall portions 231 and 231 and the anchor clip 25 is covered from above by a joint cover 24 having a substantially Ω shape in sectional view provided with skirt portions 24a and 24a on both sides. . In the interior of the joint cover 24, a waterproof material 26 having an adhesive layer 26a provided on the bottom surface formed of synthetic rubber or the like is accommodated.
本実施の形態の陸屋根部11では、図4に示すように目地カバー24が接合部13に略直交する向きに、換言すると陸屋根部11の桁側に設けられるパラペット部28(パラペット本体28a参照)と略平行となる向きに延設される。   In the flat roof portion 11 of the present embodiment, as shown in FIG. 4, the joint cover 24 is arranged in a direction substantially orthogonal to the joint portion 13, in other words, the parapet portion 28 provided on the girder side of the flat roof portion 11 (see the parapet main body 28 a). It is extended in the direction which becomes substantially parallel.
以上のようにして構築される陸屋根部11の端縁111は、図1に示すように傾斜屋根部12の上縁121よりも外側に庇状に突出される。すなわち、陸屋根部11の端縁111においては、下地板21よりも外側に溝板23と目地カバー24とが張り出している。   As shown in FIG. 1, the end edge 111 of the land roof portion 11 constructed as described above protrudes in a bowl shape outward from the upper edge 121 of the inclined roof portion 12. In other words, the groove plate 23 and the joint cover 24 project outside the base plate 21 at the edge 111 of the flat roof portion 11.
なお、下地板21は、その下方のたる木20A,20Bによって支持されている。また、たる木20A,20Bは、天井梁27によって支持され、その天井梁27の下面は天井27aで覆われている。   Note that the base plate 21 is supported by the trees 20A and 20B below. The rafters 20A and 20B are supported by a ceiling beam 27, and the lower surface of the ceiling beam 27 is covered with a ceiling 27a.
一方、傾斜屋根部12も同様に、たる木40と受木桟44によって下地板41が支持されるとともに、その下方は傾斜面となる傾斜天井45によって覆われている。   On the other hand, the sloped roof portion 12 is similarly supported by a base plate 41 by a rafter 40 and a receiving bar 44, and the lower part thereof is covered by an inclined ceiling 45 serving as an inclined surface.
傾斜屋根部12の下地板41の上にはルーフィング42が敷設され、そのルーフィング42の上に台形板状の屋根面材43が隙間無く設置される。そして、傾斜屋根部12の上縁121は、図1に示すように庇状に突出された溝板23及び目地カバー24に覆われる位置まで延設される。   A roofing 42 is laid on the base plate 41 of the inclined roof portion 12, and a trapezoidal plate-like roof surface material 43 is installed on the roofing 42 without a gap. And the upper edge 121 of the inclined roof part 12 is extended to the position covered with the groove plate 23 and the joint cover 24 which protruded like a bowl as shown in FIG.
この突出された溝板23及び目地カバー24の縁部に沿って、軒先カバー31が取り付けられる。軒先カバー31は、図1,4に示すように、例えばフッ素鋼板などの金属板を断面視逆L字形に加工することによって成形される。   An eaves tip cover 31 is attached along the edge of the protruding groove plate 23 and joint cover 24. As shown in FIGS. 1 and 4, the eaves cover 31 is formed by processing a metal plate such as a fluorine steel plate into an inverted L shape in cross section.
軒先カバー31は、目地カバー24上に設置させる帯状の上縁部31aと、上縁部31aの側縁から垂下される垂下壁31dと、垂下壁31dの下端から傾斜屋根部12の上面と略平行となるように延設される下縁部31bとを備えている。   The eaves edge cover 31 has a belt-like upper edge 31a installed on the joint cover 24, a hanging wall 31d hanging from the side edge of the upper edge 31a, and the upper surface of the inclined roof 12 from the lower end of the hanging wall 31d. And a lower edge portion 31b extending so as to be parallel to each other.
軒先カバー31は、上縁部31aがリベット33によって陸屋根部11の目地カバー24上面に固定される。そして、庇状に突出された溝板23及び目地カバー24の側端面は、軒先カバー31の上縁部31a及び垂下壁31dによって覆われることになる。   The eaves edge cover 31 is fixed to the upper surface of the joint cover 24 of the land roof portion 11 with an upper edge portion 31 a by a rivet 33. Then, the side end surfaces of the groove plate 23 and the joint cover 24 protruding in a hook shape are covered by the upper edge portion 31a and the hanging wall 31d of the eaves tip cover 31.
また、軒先カバー31の下縁部31bは、傾斜屋根部12の上面から離隔した位置、すなわち浮いた位置に配置される。そして、この軒先カバー31の下縁部31bと傾斜屋根部12の上面との間には、水切り材32が配置される。   Further, the lower edge portion 31 b of the eaves edge cover 31 is disposed at a position separated from the upper surface of the inclined roof portion 12, that is, at a floating position. A draining material 32 is disposed between the lower edge portion 31 b of the eaves edge cover 31 and the upper surface of the inclined roof portion 12.
水切り材32は、図1に示すように、例えばフッ素鋼板などの金属板を断面視7字形に加工することによって成形される。この水切り材32は、溝板23の下面に沿って取り付けられる帯状の上縁部32aと、上縁部32aの内側の側縁から軒先カバー31の下縁部31bと傾斜屋根部12との略中間に向けて延設される本体部32bとを備えている。   As shown in FIG. 1, the draining material 32 is formed by processing a metal plate such as a fluorine steel plate into a 7-letter shape in cross section. The draining material 32 is an abbreviation of a strip-like upper edge portion 32 a attached along the lower surface of the groove plate 23, and a lower edge portion 31 b of the eaves edge cover 31 and the inclined roof portion 12 from the inner side edge of the upper edge portion 32 a. And a main body 32b extending toward the middle.
この水切り材32の本体部32bは、軒先カバー31の下縁部31bと略平行になるように延設される。また、本体部32bは、軒先カバー31の下縁部31bよりも下方まで突出している。よって、軒先カバー31を伝って流れ落ちた雨水は、水切り材32上に落ちて傾斜屋根部12に流れることになる。   The body portion 32 b of the draining material 32 extends so as to be substantially parallel to the lower edge portion 31 b of the eaves edge cover 31. Further, the main body 32 b protrudes below the lower edge 31 b of the eaves edge cover 31. Therefore, the rainwater that has flowed down along the eaves edge cover 31 falls on the draining material 32 and flows to the inclined roof portion 12.
そして、軒先カバー31の下縁部31bと水切り材32の本体部32bとは、Z字状のZ金具31cによって接続される。すなわち、Z金具31cの上片がリベット33によって下縁部31bの裏面に固定される。また、Z金具31cの下片がリベット33によって本体部32bの表面に固定される。   And the lower edge part 31b of the eaves edge cover 31 and the main-body part 32b of the draining material 32 are connected by the Z-shaped Z metal fitting 31c. That is, the upper piece of the Z metal fitting 31 c is fixed to the back surface of the lower edge portion 31 b by the rivet 33. Further, the lower piece of the Z metal fitting 31c is fixed to the surface of the main body portion 32b by the rivet 33.

次に、本実施の形態の屋根10及びそれを備えたユニット建物1の作用について説明する。   Next, the operation of the roof 10 of the present embodiment and the unit building 1 having the roof 10 will be described.
このように構成された本実施の形態の屋根10は、陸屋根部11と傾斜屋根部12との接合部13に、陸屋根部11の傾斜屋根部側に庇状に突出される軒先カバー31と、その下に配置される水切り材32とを備えている。   The roof 10 of the present embodiment configured as described above has an eaves tip cover 31 projecting in a bowl shape on the inclined roof portion side of the land roof portion 11 at the joint portion 13 between the land roof portion 11 and the inclined roof portion 12, and A draining material 32 is provided below.
このため、地上から見ると陸屋根部11と傾斜屋根部12とが連続しているような外観が創出される。すなわち、折板屋根材の凸部の高さに比べて低い高さの壁部231が設けられた溝板23,・・・によって陸屋根部11を構築することで、端縁111においても上方への突出量が抑えられる。これにより、端縁111を隠すための高いパラペットを接合部13に設けなくてもよくなり、陸屋根部11と傾斜屋根部12とが一体になったような外観にすることができる。   For this reason, when it sees from the ground, the external appearance that the land roof part 11 and the inclined roof part 12 are continuing is created. That is, by constructing the flat roof portion 11 by the groove plate 23 provided with the wall portion 231 having a height lower than the height of the convex portion of the folded plate roof material, the edge 111 also moves upward. The protruding amount of is suppressed. Thereby, it is not necessary to provide a high parapet for hiding the edge 111 in the joint portion 13, and an appearance as if the land roof portion 11 and the inclined roof portion 12 are integrated can be obtained.
また、軒先カバー31の下方に水切り材32を重ねた二重の防水処理となるため、防水性能に優れた接合部13にすることができる。すなわち、軒先カバー31を張り出させ、その下縁部31bと水切り材32の表面とを接続する構成であれば、軒先カバー31から水切り材32に連続して水が流れる構造となって、陸屋根部11と傾斜屋根部12との接合部13における漏水を抑えることができる。   Moreover, since it becomes the double waterproofing process which piled up the draining material 32 under the eaves end cover 31, it can be set as the junction part 13 excellent in waterproof performance. That is, if the eaves end cover 31 is overhanged and the lower edge portion 31b and the surface of the draining material 32 are connected, a structure in which water continuously flows from the eaves end cover 31 to the draining material 32 is obtained. Water leakage at the joint portion 13 between the portion 11 and the inclined roof portion 12 can be suppressed.
また、陸屋根部11と傾斜屋根部12との接合部13の端部に、陸屋根部11のパラペット部28及び傾斜屋根部12のケラバ部47に繋がる出隅カバー5が設置される構成であれば、屋根10のコーナー部においても一体感のある外観を創出することができる。   In addition, if the end corner cover 5 connected to the parapet portion 28 of the land roof portion 11 and the keraba portion 47 of the inclined roof portion 12 is installed at the end of the joint portion 13 between the land roof portion 11 and the inclined roof portion 12, Also, it is possible to create an external appearance with a sense of unity at the corner of the roof 10.
さらに、コーナー部に設置される出隅カバー5の接続金具51を傾斜屋根部12の水上カバー47aの上端に挿入できれば、地上からは出隅カバー5と傾斜屋根部12のケラバ部47とが連続しているように見える。また、接続金具51に水上カバー47aを挿し込むだけでよいため、接続作業が簡単である。   Furthermore, if the connection fitting 51 of the protruding corner cover 5 installed in the corner portion can be inserted into the upper end of the water cover 47a of the inclined roof portion 12, the protruding corner cover 5 and the keraba portion 47 of the inclined roof portion 12 are continuous from the ground. Looks like you are doing. Moreover, since it is only necessary to insert the water cover 47a into the connection fitting 51, the connection work is simple.
そして、出隅カバー5に傾斜屋根部12上面との間のシーリング材35を押え付ける重ね片部53aを設けておくことによって、屋根10のコーナー部周辺の防水処理を簡単におこなうことができる。   And by providing the overlapping corner part 53a which presses the sealing material 35 between the inclination roof part 12 upper surface in the protruding corner cover 5, the waterproof process of the corner part periphery of the roof 10 can be performed easily.
