＜垂木部材について＞
　次に、図６は図３の垂木部材７８を示す斜視図であり、図７は図６の垂木部材７８を示す正面図である。なお、図６で、図３の野地板７０を合わせて示している。本実施の形態の垂木部材７８は、角形金属管によって構成されている。また、本実施の形態の垂木部材７８は、閉鎖断面を有している。より具体的には、本実施の形態の垂木部材７８は、長壁７８０及び短壁７８１を有する断面長方形状の角形金属管によって構成されている。長壁７８０及び短壁７８１は、垂木部材７８の壁部を構成する。図７に示すように、本実施の形態の垂木部材７８は、長壁７８０の延在方向を上下方向とし、短壁７８１の上に図３の野地板７０が載せられるように適合されている。但し、角形金属管の断面形状は、任意であり、例えば正方形又は台形等の他の形状であってもよい。垂木部材７８が閉鎖断面を有する角形金属管とされることで、垂木部材７８を薄肉化して軽量化しても強度を確保でき、施工性を向上できる。また、仮に垂木部材７８が木材で構成されていると垂木部材７８に撓みが生じ、各屋根ユニット２１～２４の配置に支障を来す虞がある。垂木部材７８を角形金属管によって構成することで、そのような虞を低減できる。 <About rafter members>
Next, FIG. 6 is a perspective view showing the rafter member 78 of FIG. 3, and FIG. 7 is a front view showing the rafter member 78 of FIG. In addition, in FIG. 6, the field board 70 of FIG. 3 is also shown. The rafter member 78 of the present embodiment is composed of a rectangular metal tube. Further, the rafter member 78 of the present embodiment has a closed cross section. More specifically, the rafter member 78 of the present embodiment is configured by a rectangular metal tube having a rectangular cross section having a long wall 780 and a short wall 781. The long wall 780 and the short wall 781 form a wall portion of the rafter member 78. As shown in FIG. 7, the rafter member 78 of the present embodiment is adapted such that the extending direction of the long wall 780 is the vertical direction and the field board 70 of FIG. 3 is placed on the short wall 781. However, the cross-sectional shape of the rectangular metal tube is arbitrary, and may be another shape such as a square or a trapezoid. Since the rafter member 78 is a rectangular metal tube having a closed cross section, strength can be secured and workability can be improved even if the rafter member 78 is thin and lightweight. If the rafter member 78 is made of wood, the rafter member 78 may be bent, which may hinder the arrangement of the roof units 21 to 24. By configuring the rafter member 78 with a rectangular metal tube, such a risk can be reduced.
　角形金属管の素材としては、冷延鋼板、ステンレス鋼板若しくはアルミニウム板又はこれらに表面処理を施したものを使用することができる。表面処理には、めっき及び塗装が含まれる。特に、めっきには、Ｚｎ－Ａｌ－Ｍｇ合金めっきが含まれる。角形金属管の肉厚は、０．８ｍｍ程度とすることができる。 As the material of the rectangular metal tube, a cold rolled steel plate, a stainless steel plate, an aluminum plate, or a material obtained by subjecting these to a surface treatment can be used. Surface treatment includes plating and painting. In particular, the plating includes Zn-Al-Mg alloy plating. The wall thickness of the rectangular metal tube can be about 0.8 mm.
　短壁７８１には、垂木部材７８の長手方向に延在されたリブ７８３が設けられている。このようなリブ７８３が短壁７８１に設けられていることで、垂木部材７８の長手方向に直交する方向に沿って垂木部材７８に加えられる外力に対する垂木部材７８の剛性を向上できる。本実施の形態のリブ７８３は、短壁７８１の幅方向に間隔を置いて配置された複数の凹部を有している。本実施の形態の複数の凹部は、第１及び第２凹部群７８３１，７８３２を形成している。第１及び第２凹部群７８３１，７８３２は、短壁７８１の幅方向に係る中央部に形成された平板部７８３３の両側に配置されている。なお、リブ７８３は、短壁７８１の幅方向に間隔を置いて配置された複数の凸部を有していてもよい。 The short wall 781 is provided with a rib 783 extending in the longitudinal direction of the rafter member 78. Since the rib 783 is provided on the short wall 781, the rigidity of the rafter member 78 against the external force applied to the rafter member 78 along the direction orthogonal to the longitudinal direction of the rafter member 78 can be improved. The rib 783 of the present embodiment has a plurality of recesses arranged at intervals in the width direction of the short wall 781. The plurality of recesses of the present embodiment form first and second recess groups 7831, 7832. The first and second recessed portion groups 7831, 7832 are arranged on both sides of a flat plate portion 7833 formed in the central portion of the short wall 781 in the width direction. The rib 783 may have a plurality of convex portions arranged at intervals in the width direction of the short wall 781.
　図７に示しているように、野地板７０を垂木部材７８に緊結するビス７８ａは、短壁７８１を貫通して垂木部材７８の内側に進入している。垂木部材７８の内側には、ビス７８ａを取り囲むように打ち抜きバリ７８４が形成されている。打ち抜きバリ７８４は、ビス７８ａに絡みつきビス７８ａの引き抜きを阻害する。 As shown in FIG. 7, the screw 78a that tightly connects the base plate 70 to the rafter member 78 penetrates the short wall 781 and enters the inside of the rafter member 78. A punching burr 784 is formed inside the rafter member 78 so as to surround the screw 78a. The punching burr 784 is entangled with the screw 78a and prevents the screw 78a from being pulled out.
　垂木部材７８には、垂木部材７８を構成する金属板（素材金属板）の両側部がカシメられたカシメ部７８５が設けられている。換言すると、本実施の形態の垂木部材７８では、素材金属板の両側部を溶接により接合していない。素材金属板として表面処理を施した金属板を用いる場合、素材金属板の両側部を溶接すると、接合部の表面処理が除去されてしまう。表面処理が除去されると接合部から腐食が生じやすくなる。また、接合部に対して表面処理の補修を行う必要が生じる。素材金属板の両側部をカシメにより接合することで、このような問題の発生を回避することができる。本実施の形態のカシメ部７８５は、素材金属板の両側部がハゼ折りされたハゼ折り部により構成されている。 The rafter member 78 is provided with a caulking portion 785 in which both sides of a metal plate (material metal plate) forming the rafter member 78 are crimped. In other words, in the rafter member 78 of the present embodiment, both sides of the raw metal plate are not joined by welding. When a surface-treated metal plate is used as the material metal plate, if the both sides of the material metal plate are welded, the surface treatment of the joint is removed. When the surface treatment is removed, corrosion tends to occur from the joint. In addition, it becomes necessary to repair the surface treatment of the joint. By joining both sides of the raw metal plate by crimping, it is possible to avoid such a problem. The crimp portion 785 of the present embodiment is configured by a goby fold portion in which both sides of the material metal plate are goby folded.

Examples of the metal plate that is the material of the front substrate 800 include hot-dip galvanized steel sheet, hot-dip aluminum-zinc alloy-plated steel sheet, hot-dip zinc-aluminum-magnesium alloy-plated steel sheet, hot-dip aluminum-plated steel sheet, hot-dip galvanized stainless steel sheet, hot-dip aluminum Zinc alloy plated stainless steel sheet, hot-dip zinc-aluminum-magnesium alloy-plated stainless steel sheet, hot-dip aluminum-plated stainless steel sheet, stainless steel sheet, Al plate, Ti plate, coated hot-dip galvanized steel sheet, hot-dip aluminum-zinc alloy-plated steel sheet, hot-dip zinc coating -Aluminum-magnesium alloy plated steel sheet, painted aluminum plated steel sheet, painted hot-dip galvanized stainless steel sheet, painted hot-dip aluminum-zinc alloy-plated stainless steel sheet, hot-dip zinc-aluminum-magnesium alloy-plated stainless steel sheet, hot-dip galvanized stainless steel sheet, painted A stainless steel plate, a coated Al plate, and a coated Ti plate can be used.
　金属板の厚みは０．５ｍｍ以下であることが好ましい。金属板の厚みの増加に伴い、平板屋根材８の強度が増大する一方で重量が増す。金属板の厚みを０．５ｍｍ以下とすることで、平板屋根材８の重量が大きくなりすぎることを回避できる。なお、金属板の厚みが０．２７ｍｍ以上であることが好ましい。金属板の厚みを０．２７ｍｍ以上とすることで、平板屋根材８として必要とされる強度を確保でき、耐風圧性能を十分に得ることができる。耐風圧性能とは、強い風に対して座屈せずに平板屋根材８が耐えられる性能である。 The metal plate preferably has a thickness of 0.5 mm or less. As the thickness of the metal plate increases, the strength of the flat roof member 8 increases while the weight increases. By setting the thickness of the metal plate to 0.5 mm or less, it is possible to prevent the weight of the flat roof member 8 from becoming too large. The metal plate preferably has a thickness of 0.27 mm or more. By setting the thickness of the metal plate to 0.27 mm or more, the strength required for the flat roof member 8 can be secured, and sufficient wind pressure resistance performance can be obtained. The wind pressure resistance performance is the performance that the flat roof member 8 can withstand without being buckled against a strong wind.
　裏基材８０１は、表基材８００の裏側の開口を塞ぐように表基材８００の裏側に配置されている。裏基材８０１としては、アルミ箔、アルミ蒸着紙、水酸化アルミ紙、炭酸カルシウム紙、樹脂フィルム又はガラス繊維紙等の軽量な素材を用いることができる。これらの軽量な素材を裏基材８０１に用いることで、平板屋根材８の重量が増大することを回避することができる。 The back substrate 801 is arranged on the back side of the front substrate 800 so as to close the opening on the back side of the front substrate 800. As the back substrate 801, a lightweight material such as aluminum foil, aluminum vapor-deposited paper, aluminum hydroxide paper, calcium carbonate paper, resin film or glass fiber paper can be used. By using these lightweight materials for the back substrate 801, it is possible to avoid an increase in the weight of the flat roof member 8.
　芯材８０２は、例えば発泡樹脂等により構成されるものであり、表基材８００と裏基材８０１との間に充填されている。表基材８００と裏基材８０１との間に芯材８０２が充填されることで、樹脂シート等の裏打ち材を表基材８００の裏側に張り付ける態様よりも、表基材８００の内部に芯材８０２を強固に密着させることができ、雨音性、断熱性等の平板屋根材８に求められる性能を向上させることができる。芯材８０２として、予め成形された板状の断熱フォームを使用してもよい。 The core material 802 is made of, for example, foam resin, and is filled between the front base material 800 and the back base material 801. By filling the core material 802 between the front base material 800 and the back base material 801, rather than a mode in which a backing material such as a resin sheet is attached to the back side of the front base material 800, The core material 802 can be firmly adhered, and the performance required for the flat roof material 8 such as rain noise and heat insulation can be improved. As the core material 802, a preformed plate-shaped heat insulating foam may be used.
　芯材８０２の素材としては、特に制限が無く、ウレタン、フェノール、ヌレート樹脂等を用いることができる。ただし、屋根材においては不燃認定材料を使用することが望ましい。不燃材料認定試験は、ＩＳＯ５６６０－１コーンカロリーメーター試験法に準拠した発熱性試験が実施される。芯材８０２となる発泡樹脂が発熱量の多いウレタンなどの場合は、表基材８００の全体としての厚みを薄くしたり、発泡樹脂に無機発泡粒子を含有させたりすることができる。 The material of the core material 802 is not particularly limited, and urethane, phenol, nurate resin or the like can be used. However, it is desirable to use non-combustible certified materials for roofing materials. As the non-combustible material certification test, a heat generation test based on the ISO5660-1 cone calorimeter test method is carried out. When the foamed resin serving as the core material 802 is urethane or the like that generates a large amount of heat, the thickness of the front substrate 800 as a whole can be reduced, or the foamed resin can contain inorganic foamed particles.
　芯材８０２が充填される表基材８００の内部空間の高さは、４ｍｍ以上かつ８ｍｍ以下とされることが好ましい。内部空間の高さを４ｍｍ以上とすることで、表基材８００の強度を十分に高くすることができ、耐風圧性を向上させることができる。断熱性についても４ｍｍ以上で良好となる。また、内部空間の高さを８ｍｍ以下とすることで、芯材８０２の有機質量が多くなりすぎることを回避して、より確実に不燃材料認定を得ることができるようにしている。 The height of the internal space of the front substrate 800 filled with the core material 802 is preferably 4 mm or more and 8 mm or less. By setting the height of the internal space to 4 mm or more, the strength of the front substrate 800 can be sufficiently increased and the wind pressure resistance can be improved. The heat insulating property is also good when it is 4 mm or more. Further, by setting the height of the internal space to be 8 mm or less, it is possible to avoid the organic mass of the core material 802 from becoming too large and to obtain the non-combustible material certification more reliably.
　図８に戻り、表基材８００の表面には、平板屋根材８の幅方向８ｗに係る両側であって、平板屋根材８が下地材７の上に配置された際に軒側に位置する場所に打込表示部８０３が設けられている。打込表示部８０３は、例えば釘又はビス等の緊結部材を平板屋根材８に打ち込む位置を表すための構成である。本実施の形態の打込表示部８０３は、平面視円形の凹部により構成されている。しかしながら、打込表示部８０３は、例えば突体、開口又は印刷若しくは刻設された記号等、緊結部材の打込み位置を作業者が視覚的又は触覚的に認識できる他の態様を採ることもできる。 Returning to FIG. 8, on the surface of the front base material 800, on both sides of the flat roof material 8 in the width direction 8w, the flat roof material 8 is located on the eaves side when placed on the base material 7. A driving display unit 803 is provided at a place. The driving-in display portion 803 is a structure for indicating a position where a binding member such as a nail or a screw is driven into the flat roof member 8. The drive-in display unit 803 of the present embodiment is configured by a concave portion having a circular shape in plan view. However, the driving-in display unit 803 can also adopt another mode in which the operator can visually or tactually recognize the driving position of the binding member, such as a protrusion, an opening, or a printed or engraved symbol.

The eaves side end of the end cover material 3 is engaged with the second engaging portion 812 provided on the suspension 81 of the flat roof material 8 of the first and second roof units 21 and 22. In addition, the end cover material 3 can be tightly bound to the base material 7 of the first to fourth roof units 21 to 24 by a fastening member 9 such as a screw or a nail. The binding member 9 is preferably driven into the end of the end cover material 3 so that the binding member 9 driven into the end cover material 3 can be covered by the side cover material 4.
＜側部カバー工程について＞
　側部カバー工程（ステップＳ４）では、突合せ部分を幅方向延出部７１ａ及び／又は奥行方向延出部７１ｂ（第１防水シート７１）により覆った後に、図２２に示すように、第１～第４屋根ユニット２１～２４の側部露出領域２１１を覆うように側部カバー材４を第１～第４屋根ユニット２１～２４の下地材７に重ねる。このとき、側部カバー材４の側部カバー材本体４０は、建物の軒方向５に関して離間する一対の平板屋根材８（例えば第１及び第２屋根ユニット２１，２２の平板屋根材８）に重ねられる。また、その側部カバー材本体４０が重ねられた一対の平板屋根材８よりも棟側に位置する平板屋根材８の下に側部カバー材本体４０の他端４０ａが挿入される。さらに、その側部カバー材本体４０が重ねられた一対の平板屋根材８の軒側端部に係合部４１が係合される。さらに、その側部カバー材本体４０が重ねられた一対の平板屋根材８の間に芯材４２が挿入される。 <About the side cover process>
In the side cover step (step S4), after the butted portion is covered with the widthwise extending portion 71a and/or the depthwise extending portion 71b (first waterproof sheet 71), as shown in FIG. The side cover material 4 is laid on the base material 7 of the first to fourth roof units 21 to 24 so as to cover the side exposed areas 211 of the fourth roof units 21 to 24. At this time, the side cover material main body 40 of the side cover material 4 becomes a pair of flat plate roofing materials 8 (for example, flat plate roofing material 8 of the first and second roof units 21 and 22) spaced apart from each other in the eaves direction 5 of the building. Can be stacked. Further, the other end 40a of the side cover material body 40 is inserted under the flat roof material 8 located on the ridge side of the pair of flat roof materials 8 on which the side cover material bodies 40 are stacked. Further, the engaging portions 41 are engaged with the eaves side end portions of the pair of flat plate roofing materials 8 on which the side cover material bodies 40 are stacked. Further, the core member 42 is inserted between the pair of flat plate roof members 8 on which the side cover member body 40 is stacked.
　このような屋根の施工方法及び屋根構造１では、屋根ユニット間の突合せ部分を防水シートが覆うので、止水性の低下を抑えつつ、屋根の施工に要する時間を短くすることができる。 In such a roof construction method and roof structure 1, since the abutting portions between the roof units are covered with the waterproof sheet, it is possible to reduce the time required for roof construction while suppressing a decrease in waterproofness.
　また、隣接する一対の屋根ユニット２のいずれか一方から幅方向延出部７１ａ及び／又は奥行方向延出部７１ｂ（第１防水シート７１）が延出されているので、屋根ユニット２を互いに隣接するように配置することに合わせて、それらの突合せ部分を幅方向延出部７１ａ及び／又は奥行方向延出部７１ｂ（第１防水シート７１）により覆うことができる。防水シートを別部材として準備する態様と比較して、より確実に止水性の低下を抑えることができるとともに、屋根の施工に要する時間をさらに短くすることができる。 Further, since the width direction extending portion 71a and/or the depth direction extending portion 71b (first waterproof sheet 71) extends from either one of the pair of adjacent roof units 2, the roof units 2 are adjacent to each other. According to such arrangement, the butted portions can be covered by the widthwise extending portion 71a and/or the depthwise extending portion 71b (first waterproof sheet 71). Compared with a mode in which a waterproof sheet is prepared as a separate member, it is possible to more reliably suppress a decrease in water shutoff and further reduce the time required for roof construction.
　さらに、奥行方向延出部７１ｂ（第１防水シート７１）が突合せ部分を跨いで端部露出領域２１０に重ねられるので、屋根の施工に要する時間をさらに短くすることができる。すなわち、仮に端部露出領域２１０まで平板屋根材８が配置されていると、平板屋根材８の下に第１防水シート７１を挿入する手間が生じるが、本実施の形態の構成を採ることによりそのような手間の発生を回避することができる。 Further, since the depth direction extending portion 71b (first waterproof sheet 71) is overlapped with the end exposed region 210 across the abutting portion, the time required for the roof construction can be further shortened. That is, if the flat roof material 8 is arranged up to the end exposed region 210, it takes time to insert the first waterproof sheet 71 under the flat roof material 8, but by adopting the configuration of the present embodiment. It is possible to avoid such trouble.
　さらにまた、端部カバー材３が棟側の屋根ユニット２の平板屋根材８の下に挿入されるとともに軒側の屋根ユニット２の平板屋根材８に重ねられるので、端部カバー材３が目立つことを回避することができるとともに、端部露出領域２１０をより確実に覆うことができる。換言すると、配列された複数の平板屋根材８の中に端部カバー材３を紛れ込ませることができる。 Furthermore, since the end cover material 3 is inserted below the flat roof material 8 of the roof unit 2 on the ridge side and is overlapped with the flat roof material 8 of the roof unit 2 on the eaves side, the end cover material 3 is conspicuous. This can be avoided, and the end exposed region 210 can be covered more reliably. In other words, the end cover member 3 can be mixed in the plurality of flat plate roof members 8 arranged.
　また、端部カバー材３が平板屋根材８であるので、端部カバー材３が目立つことをより確実に回避することができる。 Also, since the end cover member 3 is the flat roof member 8, it is possible to more reliably prevent the end cover member 3 from standing out.
　さらに、幅方向延出部７１ａ（第１防水シート７１）が突合せ部分を跨いで側部露出領域２１１に重ねられるので、屋根の施工に要する時間をさらに短くすることができる。すなわち、仮に側部露出領域２１１まで平板屋根材８が配置されていると、平板屋根材８の下に第１防水シート７１を挿入する手間が生じるが、本実施の形態の構成を採ることによりそのような手間の発生を回避することができる。 Further, since the widthwise extending portion 71a (first waterproof sheet 71) is overlapped with the side exposed area 211 across the abutting portion, the time required for roof construction can be further shortened. That is, if the flat roof material 8 is arranged up to the side exposed area 211, it takes time to insert the first waterproof sheet 71 under the flat roof material 8, but by adopting the configuration of the present embodiment. It is possible to avoid such trouble.
　さらにまた、各屋根ユニット２が建物の軒方向５に関して互いの側部露出領域２１１が隣接するように配置されるので、運搬時及び設置時に各屋根ユニット２の平板屋根材８の端部が破損する虞を低減できる。また、第１防水シート７１に不具合が生じた場合に、屋根ユニット２間の突合せ部分に対して防水テープを貼付する等の補修を行うことができる。 Furthermore, since the roof units 2 are arranged such that their side exposed areas 211 are adjacent to each other with respect to the eaves direction 5 of the building, the ends of the flat roof members 8 of the roof units 2 are damaged during transportation and installation. It is possible to reduce the risk of Further, when a problem occurs in the first waterproof sheet 71, repairs such as attaching a waterproof tape to the abutting portions between the roof units 2 can be performed.
　また、建物の軒方向５に関して離間する一対の平板屋根材８に側部カバー材本体４０が重ねられるとともに、一対の平板屋根材８よりも棟側に位置する平板屋根材８の下に側部カバー材本体４０の他端４０ａが挿入され、一対の平板屋根材８の軒側端部に係合部４１が係合されるように配置されるので、側部カバー材４が目立つことを回避しつつ、屋根ユニット２の側部露出領域２１１をより確実に覆うことができる。換言すると、配列された複数の平板屋根材８の中に側部カバー材４を紛れ込ませることができる。 Further, the side cover material main body 40 is superposed on the pair of flat plate roofing materials 8 spaced apart from each other in the eaves direction 5 of the building, and the side portions are below the flat plate roofing material 8 located on the ridge side of the pair of flat plate roofing materials 8. Since the other end 40a of the cover material main body 40 is inserted and the eaves side end portions of the pair of flat plate roof members 8 are arranged so that the engaging portions 41 are engaged, the side cover member 4 is prevented from standing out. At the same time, the side exposed region 211 of the roof unit 2 can be covered more reliably. In other words, the side cover member 4 can be mixed in the plurality of flat plate roof members 8 arranged.
　さらに、側部カバー材本体４０の裏面側に配置されるとともに、一対の平板屋根材８の間に挿入される芯材４２を側部カバー材４がさらに有しているので、側部カバー材４の遮音性能を向上できるとともに、側部カバー材４の踏み潰れ性能を向上できる。 Furthermore, since the side cover material 4 further has a core member 42 which is arranged on the back surface side of the side cover material body 40 and is inserted between the pair of flat plate roof materials 8, the side cover material 4 is provided. It is possible to improve the sound insulation performance of No. 4 and the crushing performance of the side cover material 4.
　さらにまた、平板屋根材８が表基材８００、裏基材８０１及び芯材８０２を有する金属屋根材であるので、屋根の重量が増大することを回避することができる。また、金属屋根材が撓みを許容するので、棟側の屋根ユニット２の平板屋根材８の下に端部カバー材３を挿入する際に平板屋根材８が損傷する虞を低減できる。さらに、側部カバー材本体４０を金属板により構成する場合に、側部カバー材本体４０と平板屋根材８との表面に違いを小さくでき意匠性を向上できる。 Furthermore, since the flat roof material 8 is a metal roof material having the front base material 800, the back base material 801, and the core material 802, it is possible to avoid an increase in the weight of the roof. Further, since the metal roof material allows the flat roof material 8 to bend, it is possible to reduce the risk that the flat roof material 8 will be damaged when the end cover material 3 is inserted under the flat roof material 8 of the roof unit 2 on the ridge side. Further, when the side cover material body 40 is made of a metal plate, the difference between the surfaces of the side cover material body 40 and the flat roof member 8 can be reduced, and the designability can be improved.
　なお、実施の形態では、隣接する一対の屋根ユニット２のいずれか一方から第１防水シート７１が延出されるように説明したが、別部材として準備された防水シートにより屋根ユニット間の突合せ部分を覆ってもよい。 In addition, in the embodiment, the first waterproof sheet 71 is described as extending from either one of the pair of adjacent roof units 2, but the waterproof sheet prepared as a separate member is used to connect the roof units to each other. You may cover it.
　また、屋根ユニット２に端部露出領域２１０又は側部露出領域２１１が設けられるように説明したが、屋根ユニットの下地材の全面が平板屋根材により覆われて、端部露出領域及び側部露出領域が設けられていなくてもよい。 Further, although the roof unit 2 is described as being provided with the end exposed region 210 or the side exposed region 211, the entire base material of the roof unit is covered with the flat roof material, and the end exposed region and the side exposed region are exposed. The area may not be provided.
　さらに、平板屋根材８が金属屋根材であるように説明したが、例えばカラーベスト等の平形屋根用スレートの平板屋根材が使用されてもよい。 Furthermore, although the flat roof material 8 is described as being a metal roof material, for example, a flat roof slate flat roof material such as a color vest may be used.
　実施の形態２．
　図２３は、本発明の実施の形態２による屋根構造１を示す斜視図である。実施の形態１では、端部カバー材３の端部に緊結部材９が打ち込まれるように説明した。しかしながら、下地材７への端部カバー材３の緊結をより強固するため、より多くの緊結部材９を端部カバー材３に打ち込む場合もある。 Embodiment 2.
FIG. 23 is a perspective view showing a roof structure 1 according to the second embodiment of the present invention. In the first embodiment, the binding member 9 is driven into the end portion of the end cover material 3. However, in order to more firmly bond the end cover material 3 to the base material 7, more binding members 9 may be driven into the end cover material 3.
　図２３に示すように、本実施の形態２では、端部カバー材３の端部に加えて建物の軒方向５に間隔を置いて複数の箇所において端部カバー材３に緊結部材９が打ち込まれている。また、それら緊結部材９を覆い隠すように緊結部材カバー３０を端部カバー材３に重ねている。すなわち、本実施の形態２の屋根の施工方法では、端部カバー材３を下地材７に重ねた後に、端部カバー材３に緊結部材９を打ち込み端部カバー材３を下地材７に緊結する工程と、端部カバー材３に打ち込まれた緊結部材９を覆い隠すように緊結部材カバー３０を端部カバー材３に重ねる工程とをさらに含む。緊結部材カバー３０が緊結部材９を覆い隠すことにより、緊結部材９の腐食を抑えることができる。 As shown in FIG. 23, in the second embodiment, the binding members 9 are driven into the end cover material 3 at a plurality of positions at intervals in the eaves direction 5 of the building in addition to the end portion of the end cover material 3. Has been. Further, the binding member cover 30 is laid on the end cover material 3 so as to cover the binding members 9. That is, in the roof construction method according to the second embodiment, after the end cover material 3 is overlaid on the base material 7, the binding member 9 is driven into the end cover material 3 to bond the end cover material 3 to the base material 7.
