次に、この屋根１の構築方法を説明する。
まず、図５(ａ)に示すように、野地板８の上に防水シート９を設置する。次に、図５(ｂ)に示すように、野地板８の軒側の端部に、１列目の固定用金具３０をネジ４３で取り付ける。次に、図５(ｃ)に示すように、その１列目の固定用金具３０の棟側に一列目の樹脂発泡体１０を載置する。次に、図５(ｄ)に示すように、その１列目の樹脂発泡体１０の棟側に、２列目の固定用金具３０をネジ４３で取り付ける。 Next, the construction method of this roof 1 is demonstrated.
First, as shown in FIG. 5 (a), a waterproof sheet 9 is installed on the field board 8. Next, as shown in FIG. 5 (b), the first row of fixing brackets 30 are attached to the end portions of the eaves side of the base plate 8 with screws 43. Next, as shown in FIG. 5C, the first row of resin foams 10 is placed on the ridge side of the first row of fixing brackets 30. Next, as shown in FIG. 5 (d), the second row of fixtures 30 is attached with screws 43 to the ridge side of the first row of resin foam 10.

次に、図６(ａ)に示すように、１列目の樹脂発泡体１０の切欠１５に接着剤４１を上側から注入する。なお、このとき、該切欠１５は、その下側が固定用金具３０の軒側延出部３３により塞がれ、軒側が固定用金具３０の第二上側延出部３４により塞がれることにより、上方に開口した有底穴状になっている。次に、図６(ｂ)に示すように、陶板屋根材２０の尻部突起２５を２列目の固定用金具３０の尻浮き防止部３５の下方に挿入する。このとき、該２列目の固定用金具３０は若干弾性変形する。次に、図６(ｃ)に示すように、陶板屋根材２０の頭部下側突起２７を上側から１列目の固定用金具３０の案内部３８に当接させる。次に、陶板屋根材２０から手を離すと、陶板屋根材２０の頭部の自重により、頭部下側突起２７が案内部３８を軒側に押すことで、図６(ｄ)に示すように、固定用金具３０を弾性変形させて、案内部３８と頭浮き防止部３７とを軒側に押し退ける。そして、頭部下側突起２７が、頭浮き防止部３７の下側に変位する。その後、図６(ｅ)に示すように、固定用金具３０の弾性力により該案内部３８と頭浮き防止部３７とが棟側に戻る。これにより、頭部下側突起２７が、頭浮き防止部３７の下側に入り込む。このとき、陶板屋根材２０の頭部の下面は接着剤４１に当接する。これにより、図６(ｆ)に示すように、１列目の樹脂発泡体１０の上に１列目の陶板屋根材２０が設置される。そして、接着剤４１が乾くと、該接着剤４１により、樹脂発泡体１０の頭部と陶板屋根材２０の頭部と固定用金具３０とが互いに接着される。 Next, as shown in FIG. 6A, an adhesive 41 is poured into the notches 15 of the resin foam 10 in the first row from above. At this time, the notch 15 is closed at its lower side by the eaves-side extension portion 33 of the fixing metal fitting 30 and is closed at the eave side by the second upper extension portion 34 of the fixing metal fitting 30. It has a bottomed hole shape that opens upward. Next, as shown in FIG. 6 (b), the bottom protrusion 25 of the ceramic roof material 20 is inserted below the bottom lifting prevention portion 35 of the second mounting fixture 30. At this time, the fixing metal fittings 30 in the second row are slightly elastically deformed. Next, as shown in FIG. 6 (c), the head lower projection 27 of the ceramic roof material 20 is brought into contact with the guide portion 38 of the fixing bracket 30 in the first row from the upper side. Next, when the hand is released from the porcelain roofing material 20, the head lower projection 27 pushes the guide part 38 toward the eaves side by the weight of the head of the porcelain roofing material 20, as shown in FIG. 6 (d). Then, the fixing bracket 30 is elastically deformed, and the guide portion 38 and the head lift prevention portion 37 are pushed away toward the eaves side. Then, the head lower protrusion 27 is displaced to the lower side of the head lifting prevention portion 37. Thereafter, as shown in FIG. 6 (e), the guide portion 38 and the head lift prevention portion 37 are returned to the ridge side by the elastic force of the fixing bracket 30. As a result, the lower head protrusion 27 enters the lower side of the head lifting prevention portion 37. At this time, the lower surface of the head of the ceramic roofing material 20 contacts the adhesive 41. As a result, as shown in FIG. 6 (f), the first-row ceramic roofing material 20 is installed on the first-row resin foam 10. When the adhesive 41 is dried, the head of the resin foam 10, the head of the ceramic roofing material 20, and the fixing bracket 30 are bonded to each other by the adhesive 41.

次に、図７(ａ)に示すように、２列目の固定用金具３０の棟側に、２列目の樹脂発泡体１０及び３列目の固定用金具３０を、１列目の樹脂発泡体１０及び２列目の固定用金具３０の場合と同様の手順で、設置する。次に、図７(ｂ)〜(ｆ)に示すように、２列目の樹脂発泡体１０の上に、２列目の陶板屋根材２０を、１列目の陶板屋根材２０の場合と同様の手順で、設置する。なお、図７(ｄ)に示すように、１列目の陶板屋根材２０の本体部２１の尻部上部とその棟側に設置しようとしている２列目の陶板屋根材２０の頭部下側突起２７との間には、隙間があり、その隙間により、頭部下側突起２７が下側に通過できるだけ、固定用金具３０が弾性変形できるようになっている。図７(ｅ)に示すように、接着剤４１が乾いて、２列目の陶板屋根材２０の頭部が２列目の固定用金具３０の軒側延出部３３と第二上側延出部３４とに接着されると、それにより、１列目の陶板屋根材２０の尻部は、より浮き上がり難くなる。 Next, as shown in FIG. 7A, the second row of the resin foam 10 and the third row of the fixing bracket 30 are placed on the ridge side of the second row of the fixing bracket 30. Installation is performed in the same procedure as in the case of the foam 10 and the fixing metal 30 in the second row. Next, as shown in FIGS. 7 (b) to 7 (f), the second row of ceramic plate roofing material 20 is placed on the second row of resin foam 10, and the first row of ceramic plate roofing material 20. Install in the same procedure. As shown in FIG. 7 (d), the upper part of the bottom part of the main body 21 of the first row of ceramic roofing material 20 and the lower side of the head of the second row of ceramic roofing material 20 to be installed on the ridge side. There is a gap between the protrusion 27 and the fixing metal 30 can be elastically deformed so that the lower head protrusion 27 can pass downward. As shown in FIG. 7 (e), the adhesive 41 is dried, and the heads of the second row of ceramic roofing materials 20 are connected to the eaves-side extensions 33 and the second upper extensions of the second row of fixing brackets 30. When bonded to the portion 34, the bottom portion of the first row of ceramic plate roofing material 20 becomes more difficult to lift.

同様の作業を繰り返すことで、３列目以降の樹脂発泡体１０、４列目以降の固定用金具３０および３列目以降の陶板屋根材２０を設置する。それにより、図１(ａ)に示す屋根１を構築する。 By repeating the same operation, the resin foam 10 after the third row, the fixing bracket 30 after the fourth row, and the ceramic roof material 20 after the third row are installed. Thereby, the roof 1 shown in FIG.

［Ｂ］各陶板屋根材２０を、その軒側と棟側との２つの固定用金具３０と接着剤４１とにより、強固に野地板８に固定できる。また、その接着剤４１による接着部分は、頭浮き防止部３７や尻浮き防止部３５よりも固定部３１側の第二上側延出部３４及び軒側延出部３３であるため、この点でも該固定が強固になる。また、このように固定用金具３０にその棟側の陶板屋根材２０の頭部を接着させることで、その軒側の陶板屋根材２０の尻部の固定（尻浮き防止）も強固になる。
［Ｃ］各固定用金具３０は、その軒側の陶板屋根材２０の尻部を固定する尻部側の固定具と、棟側の陶板屋根材２０の頭部を固定する頭部側の固定具とを兼ねているので、少ない数の固定用金具３０で陶板屋根材２０を効率的に保持することができる。
［Ｄ］図６(ｃ)〜(ｅ)や図７(ｃ)〜(ｅ)に示すように、固定用金具３０の案内部３８に上側から陶板屋根材２０の頭部下側突起２７を押し当てるだけで、その頭部下側突起２７を固定用金具３０の頭浮き防止部３７の下方に配することができるので、屋根１の構築作業を効率的に行うことができる。 According to the present embodiment, the following effects can be obtained.
