Description

屋根構造及びそれに用いるケラバ水切役物Roof structure and keraba drainage material used for it
　本発明は、屋根の妻側における屋根構造及びそれに用いるケラバ水切役物に関する。 The present invention relates to a roof structure on the gable side of the roof and a keraba drainage material used for the roof structure.
　従来用いられていたこの種の屋根構造及びそれに用いるケラバ水切役物としては、例えば下記の特許文献１等に示されている屋根構造及びそれに用いるケラバ水切役物を挙げることができる。すなわち、従来構成では、屋根の妻側に配置されるケラバ水切役物（ケラバカバー材）を、水切部材（水切り部）とケラバ部材（カバー部）との二つの部材により構成している。水切部材は、野地板に重ねられるとともにのぼり木部材の反妻側の側壁部を覆うための部材である。ケラバ部材は、のぼり木部材の妻側の側壁部及び上壁部を覆うための部材である。 Examples of the conventionally used roof structure of this type and the keraba drainage accessory used therefor include the roof structure shown in Patent Document 1 and the like below and the keraba drainage accessory used therein. That is, in the conventional configuration, the keraba draining accessory (keraba cover material) arranged on the gable side of the roof is composed of two members, a draining member (draining portion) and a keraba member (cover portion). The drainage member is a member that is laminated on the field board and covers the side wall portion on the anti-gable side of the climbing wood member. The keraba member is a member for covering the side wall portion and the upper wall portion on the gable side of the climbing tree member.
　水切部材には、のぼり木部材の反妻側の側壁部に沿うように起立された起立片と、起立片の上端部から反妻側に延出された係止辺とが設けられている。ケラバ部材には、のぼり木部材及び水切部材の係止辺の上方に配置される天板と、天板の反妻側端部から下方かつ妻側に延出された斜辺とが設けられている。野地板の上に水切部材を配置した後、ケラバ部材の天板と斜辺との間に係止辺を進入させるようにケラバ部材が配置される。例えば釘等の緊結部材により、野地板に水切部材が緊結されるとともに、のぼり木部材にケラバ部材が緊結される。一般に、のぼり木部材は木製の角材により構成される。 The drainage member is provided with a standing piece standing along the side wall on the anti-gable side of the climbing tree member and a locking side extending from the upper end of the standing piece to the anti-gable side. The keraba member is provided with a top plate arranged above the locking side of the climbing wood member and the drainage member, and a hypotenuse extending downward from the anti-gable end of the top plate and extending to the gable side. .. After arranging the drainage member on the field plate, the keraba member is arranged so that the locking side is inserted between the top plate and the hypotenuse of the keraba member. For example, a draining member is bound to the field board by a binding member such as a nail, and a keraba member is bound to the climbing wood member. Generally, the climbing wood member is composed of wooden square timber.

　屋根は直射日光や風雨に曝される。このため、のぼり木部材が木製の角材により構成されている場合、のぼり木部材は大きな温度変化に曝されて徐々に劣化し、のぼり木部材へのケラバ部材の緊結が弱まってしまう。 The roof is exposed to direct sunlight and wind and rain. Therefore, when the climbing wood member is made of wooden square timber, the climbing wood member is gradually deteriorated by being exposed to a large temperature change, and the binding of the keraba member to the climbing wood member is weakened.
　上記のような従来構成では、ケラバ部材の天板と斜辺との間に水切部材の係止辺を進入させているだけであるので、のぼり木部材へのケラバ部材の緊結が弱まった際に台風等の強風に耐えることができず、ケラバ部材が吹き飛ばされる虞がある。 In the conventional configuration as described above, since the locking side of the drainage member is only inserted between the top plate of the keraba member and the hypotenuse, a typhoon occurs when the binding of the keraba member to the climbing tree member is weakened. There is a risk that the keraba member will be blown off because it cannot withstand strong winds such as.
　本発明は、上記のような課題を解決するためになされたものであり、その目的は、強風によりケラバ部材が吹き飛ばされる虞を低減できる屋根構造及びそれに用いるケラバ水切役物を提供することである。 The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a roof structure capable of reducing the risk of the keraba member being blown off by a strong wind, and a keraba drainage agent used for the roof structure. ..

＜垂木部材について＞
　次に、図２及び図１を参照しながら垂木部材４について説明する。図２は、図１の垂木部材４を示す斜視図である。図２に示すように、本実施の形態の垂木部材４は閉鎖断面を有する角形金属管によって構成されている。より具体的には、本実施の形態の垂木部材４は、長壁４０及び短壁４１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４０及び短壁４１は、垂木部材４の壁部を構成する。図１に示すように、本実施の形態の垂木部材４は、長壁４０の延在方向を上下方向とし、短壁４１の上に野地板１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。 <About rafter members>
Next, the rafter member 4 will be described with reference to FIGS. 2 and 1. FIG. 2 is a perspective view showing the rafter member 4 of FIG. As shown in FIG. 2, the rafter member 4 of the present embodiment is composed of a square metal pipe having a closed cross section. More specifically, the rafter member 4 of the present embodiment is composed of a rectangular metal pipe having a rectangular cross section having a long wall 40 and a short wall 41. The long wall 40 and the short wall 41 form a wall portion of the rafter member 4. As shown in FIG. 1, the rafter member 4 of the present embodiment is adapted so that the long wall 40 extends in the vertical direction and the field plate 1 is placed on the short wall 41. However, the cross-sectional shape of the square metal tube is arbitrary, and may be another shape such as a square or a trapezoid.
　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 square metal tube, a cold-rolled steel plate, a stainless steel plate, an aluminum plate, or a surface-treated material thereof can be used. Surface treatments include plating and painting. In particular, the plating includes Zn—Al—Mg alloy plating. The wall thickness of the square metal tube can be about 0.8 mm.
　短壁４１には、垂木部材４の長手方向に延在されたリブ４３が設けられている。このようなリブ４３が短壁４１に設けられていることで、垂木部材４の長手方向に直交する方向に沿って垂木部材４に加えられる外力に対する垂木部材４の剛性を向上できる。本実施の形態のリブ４３は、短壁４１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４３１，４３２を形成している。第１及び第２凹部群４３１，４３２は、短壁４１の幅方向に係る中央部に形成された平板部４３３の両側に配置されている。なお、リブ４３は、短壁４１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 41 is provided with a rib 43 extending in the longitudinal direction of the rafter member 4. By providing such a rib 43 on the short wall 41, the rigidity of the rafter member 4 with respect to an external force applied to the rafter member 4 along the direction orthogonal to the longitudinal direction of the rafter member 4 can be improved. The rib 43 of the present embodiment has a plurality of recesses arranged at intervals in the width direction of the short wall 41. The plurality of recesses of the present embodiment form first and second recess groups 431 and 432. The first and second recess groups 431 and 432 are arranged on both sides of the flat plate portion 433 formed in the central portion of the short wall 41 in the width direction. The rib 43 may have a plurality of convex portions arranged at intervals in the width direction of the short wall 41.
　垂木部材４には、垂木部材４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４５が設けられている。換言すると、本実施の形態の垂木部材４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４５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 4 is provided with a crimped portion 45 in which both side portions of the metal plate (material metal plate) constituting the rafter member 4 are crimped. In other words, in the rafter member 4 of the present embodiment, both side portions of the material metal plate are not joined by welding. When a surface-treated metal plate is used as the material metal plate, if both sides of the material metal plate are welded, the surface treatment of the joint portion is removed. When the surface treatment is removed, corrosion is likely to occur from the joint. In addition, it will be necessary to repair the surface treatment of the joint. By joining both sides of the material metal plate by caulking, it is possible to avoid the occurrence of such a problem. The crimped portion 45 of the present embodiment is composed of a goby-folded portion in which both side portions of the material metal plate are goby-folded.
　図１に示しているように、のぼり木部材３を緊結する緊結部材７は、垂木部材４の上方から短壁４１を貫通して垂木部材４の内側に進入している。短壁４１の内側には、緊結部材７を取り囲むように打ち抜きバリ４１ａが形成される。打ち抜きバリ４１ａは、緊結部材７に絡みつき緊結部材７の引き抜きを阻害する。 As shown in FIG. 1, the binding member 7 that binds the climbing tree member 3 penetrates the short wall 41 from above the rafter member 4 and enters the inside of the rafter member 4. A punching burr 41a is formed inside the short wall 41 so as to surround the binding member 7. The punching burr 41a is entangled with the binding member 7 and hinders the pulling out of the binding member 7.
　なお、垂木部材４が必ず金属管でなければならないわけでなく、例えば木材等の他の材料によって垂木部材４を構成してもよい。木材又は他の材料により垂木部材４を構成するとき、垂木部材４は中実構造であってもよい。すなわち、垂木部材４の内部が空洞でなくてもよい。 Note that the rafter member 4 does not necessarily have to be a metal pipe, and the rafter member 4 may be made of other materials such as wood. When the rafter member 4 is constructed of wood or other material, the rafter member 4 may have a solid structure. That is, the inside of the rafter member 4 does not have to be hollow.
＜のぼり木部材について＞
　次に、図３、図４及び図１を参照しながら、のぼり木部材３について説明する。図３は、図１ののぼり木部材３を示す斜視図である。図４は、図３ののぼり木部材３の変形例を示す斜視図である。図３に示すように、本実施の形態ののぼり木部材３は断面形状が非矩形の異形部材によって構成されている。具体的には、のぼり木部材３は、のぼり木部材本体３０と、のぼり木部材本体３０からのぼり木部材３の幅方向３ａに係る外方に突出された鍔部３１とを有している。 <About climbing wood members>
Next, the climbing tree member 3 will be described with reference to FIGS. 3, 4, and 1. FIG. 3 is a perspective view showing the climbing tree member 3 of FIG. FIG. 4 is a perspective view showing a modified example of the climbing tree member 3 of FIG. As shown in FIG. 3, the climbing tree member 3 of the present embodiment is composed of a deformed member having a non-rectangular cross-sectional shape. Specifically, the climbing tree member 3 has a climbing tree member main body 30 and a flange portion 31 protruding outward from the climbing tree member main body 30 in the width direction 3a of the climbing tree member 3.
　のぼり木部材本体３０は、のぼり木部材３の鍔部３１を除く部分である。本実施の形態ののぼり木部材本体３０は、断面矩形の外形を有している。本実施の形態ののぼり木部材本体３０には、第１下壁部３００、第１側壁部３０１、上壁部３０２、第２側壁部３０３及び第２下壁部３０４が設けられている。 The climbing tree member main body 30 is a portion of the climbing tree member 3 excluding the flange portion 31. The climbing tree member main body 30 of the present embodiment has an outer shape having a rectangular cross section. The climbing tree member main body 30 of the present embodiment is provided with a first lower wall portion 300, a first side wall portion 301, an upper wall portion 302, a second side wall portion 303, and a second lower wall portion 304.
　第１及び第２下壁部３００，３０４は、のぼり木部材３の下部において、のぼり木部材３の幅方向３ａに延在された壁部である。第１及び第２下壁部３００，３０４は幅方向３ａに互いに離間して設けられており、これら第１及び第２下壁部３００，３０４の間には開口３０５が設けられている。幅方向３ａに係るのぼり木部材３の下部の中央位置は開口３０５の位置に設けられている。但し、図４に示すように、のぼり木部材３が閉鎖断面を有していてもよい。すなわち、第１及び第２下壁部３００，３０４が互いに接続されていてもよい。 The first and second lower wall portions 300 and 304 are wall portions extending in the width direction 3a of the climbing tree member 3 at the lower part of the climbing tree member 3. The first and second lower wall portions 300 and 304 are provided apart from each other in the width direction 3a, and an opening 305 is provided between the first and second lower wall portions 300 and 304. The central position of the lower part of the climbing tree member 3 in the width direction 3a is provided at the position of the opening 305. However, as shown in FIG. 4, the climbing tree member 3 may have a closed cross section. That is, the first and second lower wall portions 300 and 304 may be connected to each other.
　第１側壁部３０１は、幅方向３ａに係る第１下壁部３００の一端から立設された壁部である。第１側壁部３０１と第１下壁部３００との間の角度は、任意であるが、本実施の形態では９０°とされている。 The first side wall portion 301 is a wall portion erected from one end of the first lower wall portion 300 related to the width direction 3a. The angle between the first side wall portion 301 and the first lower wall portion 300 is arbitrary, but is 90 ° in the present embodiment.
　上壁部３０２は、第１側壁部３０１の上端からのぼり木部材３の幅方向３ａに延出された壁部である。第１側壁部３０１と上壁部３０２との間の角度は、任意であるが、本実施の形態では９０°とされている。 The upper wall portion 302 is a wall portion extending in the width direction 3a of the climbing tree member 3 from the upper end of the first side wall portion 301. The angle between the first side wall portion 301 and the upper wall portion 302 is arbitrary, but is 90 ° in the present embodiment.
　第２側壁部３０３は、幅方向３ａに係る第２下壁部３０４の一端から立設された壁部である。第２側壁部３０３と第２下壁部３０４との間の角度は、任意であるが、本実施の形態では９０°とされている。のぼり木部材３の高さ方向３ｂに係る第２側壁部３０３の延在幅は、屋根材２の厚み以上に設定される。 The second side wall portion 303 is a wall portion erected from one end of the second lower wall portion 304 related to the width direction 3a. The angle between the second side wall portion 303 and the second lower wall portion 304 is arbitrary, but is 90 ° in the present embodiment. The extending width of the second side wall portion 303 related to the height direction 3b of the climbing wood member 3 is set to be equal to or larger than the thickness of the roofing material 2.
　鍔部３１は、第２側壁部３０３から幅方向３ａに係る外方（第１側壁部３０１から遠ざかる方向）に向かって突出された部分である。鍔部３１は、第２側壁部３０３の上部に配置されている。第２側壁部３０３の外面を基準とする幅方向３ａに係る鍔部３１の突出幅は、２０～１００ｍｍであることが好ましい。突出幅を２０ｍｍ以上とすることで、屋根材２の切断面に向かう日光を遮ることができる。突出幅を１００ｍｍ以下とすることで、強風時にのぼり木部材３等が受ける圧力抵抗を抑えることができる。 The collar portion 31 is a portion protruding from the second side wall portion 303 toward the outside (direction away from the first side wall portion 301) related to the width direction 3a. The collar portion 31 is arranged above the second side wall portion 303. The protruding width of the flange portion 31 in the width direction 3a with respect to the outer surface of the second side wall portion 303 is preferably 20 to 100 mm. By setting the protruding width to 20 mm or more, it is possible to block sunlight toward the cut surface of the roofing material 2. By setting the protruding width to 100 mm or less, it is possible to suppress the pressure resistance received by the climbing tree member 3 and the like in a strong wind.
　鍔部３１の断面形状は矩形又は台形等の任意の形状とすることができるが、本実施の形態の鍔部３１の断面形状は三角形とされている。本実施の形態の鍔部３１は、延長壁部３１０及び接続壁部３１１を有している。 The cross-sectional shape of the collar portion 31 can be any shape such as a rectangle or a trapezoid, but the cross-sectional shape of the collar portion 31 of the present embodiment is a triangle. The collar portion 31 of the present embodiment has an extension wall portion 310 and a connecting wall portion 311.
　延長壁部３１０は、第２側壁部３０３よりも幅方向３ａに係る外方に向かって上壁部３０２が延長された壁部である。 The extension wall portion 310 is a wall portion in which the upper wall portion 302 is extended outward in the width direction 3a from the second side wall portion 303.
　接続壁部３１１は、延長壁部３１０の一端と第２側壁部３０３の上端とを接続する壁部である。本実施の形態の接続壁部３１１は、延長壁部３１０の先端から第２側壁部３０３の上端に向かってのぼり木部材３の高さ方向３ｂに対して傾斜して延在されている。本実施の形態では延長壁部３１０と接続壁部３１１との間の角度は鋭角とされている。これら延長壁部３１０と接続壁部３１１との間の角度は、屋根材２の切断面に向かう日光を鍔部３１によって遮ることができるように、第２側壁部３０３の外面を基準とする幅方向３ａに係る鍔部３１の突出幅とともに決めることができる。上述のように鍔部３１の突出幅を２０～１００ｍｍとしたとき、延長壁部３１０と接続壁部３１１との間の角度は２０°以上かつ６０°以下であることが好ましい。本実施の形態では、延長壁部３１０と接続壁部３１１との間の角度が３８°とされている。 The connection wall portion 311 is a wall portion that connects one end of the extension wall portion 310 and the upper end of the second side wall portion 303. The connecting wall portion 311 of the present embodiment extends from the tip end of the extension wall portion 310 toward the upper end of the second side wall portion 303 so as to be inclined with respect to the height direction 3b of the climbing tree member 3. In the present embodiment, the angle between the extension wall portion 310 and the connection wall portion 311 is an acute angle. The angle between the extension wall portion 310 and the connection wall portion 311 is a width based on the outer surface of the second side wall portion 303 so that sunlight toward the cut surface of the roofing material 2 can be blocked by the flange portion 31. It can be determined together with the protruding width of the flange portion 31 according to the direction 3a. When the protruding width of the collar portion 31 is 20 to 100 mm as described above, the angle between the extension wall portion 310 and the connection wall portion 311 is preferably 20 ° or more and 60 ° or less. In the present embodiment, the angle between the extension wall portion 310 and the connection wall portion 311 is 38 °.
　本実施の形態ののぼり木部材３は、金属板の成形体である。具体的には、のぼり木部材３は金属板が折り曲げられることにより成形されたものである。上述の第１下壁部３００、第１側壁部３０１、上壁部３０２、第２側壁部３０３及び第２下壁部３０４並びに延長壁部３１０及び接続壁部３１１は互いに一体に形成されている。のぼり木部材３が金属板の成形体であることにより、のぼり木部材３が木材によって構成される場合と比較して、のぼり木部材３の劣化によりのぼり木部材３及びケラバ部材６２の緊結が弱まる虞を低減できる。 The climbing wood member 3 of the present embodiment is a molded body of a metal plate. Specifically, the climbing wood member 3 is formed by bending a metal plate. The first lower wall portion 300, the first side wall portion 301, the upper wall portion 302, the second side wall portion 303, the second lower wall portion 304, the extension wall portion 310, and the connecting wall portion 311 are integrally formed with each other. .. Since the climbing wood member 3 is a molded body of a metal plate, the tightness between the climbing wood member 3 and the keraba member 62 is weakened due to the deterioration of the climbing wood member 3 as compared with the case where the climbing wood member 3 is made of wood. The risk can be reduced.
　図１に示すように、本実施の形態ののぼり木部材３は、第１及び第２下壁部３００，３０４を野地板１の上面に載せるように配置される。このとき、第１下壁部３００及び第１側壁部３０１が屋根の妻側に位置するように配置される。また、第２側壁部３０３、第２下壁部３０４及び鍔部３１が反妻側に位置するように配置される。換言すると、第２側壁部３０３、第２下壁部３０４及び鍔部３１は、第１下壁部３００及び第１側壁部３０１と比較して、屋根の妻側端部から離れた位置に配置される。 As shown in FIG. 1, the climbing tree member 3 of the present embodiment is arranged so that the first and second lower wall portions 300 and 304 are placed on the upper surface of the field plate 1. At this time, the first lower wall portion 300 and the first side wall portion 301 are arranged so as to be located on the gable side of the roof. Further, the second side wall portion 303, the second lower wall portion 304, and the flange portion 31 are arranged so as to be located on the anti-gable side. In other words, the second side wall portion 303, the second lower wall portion 304, and the flange portion 31 are arranged at positions away from the gable side end of the roof as compared with the first lower wall portion 300 and the first side wall portion 301. Will be done.
　第１下壁部３００は妻側の下壁部を構成し、第２下壁部３０４は反妻側の下壁部を構成する。第１下壁部３００は、幅方向３ａに係るのぼり木部材３の下部の中央位置よりも妻側に位置する。また、第２下壁部３０４は、中央位置よりも反妻側に位置する。第１側壁部３０１はのぼり木部材３の妻側の側壁を構成し、第２側壁部３０３はのぼり木部材３の反妻側の側壁を構成する。 The first lower wall portion 300 constitutes the lower wall portion on the gable side, and the second lower wall portion 304 constitutes the lower wall portion on the anti-gable side. The first lower wall portion 300 is located on the gable side of the central position of the lower portion of the climbing tree member 3 in the width direction 3a. Further, the second lower wall portion 304 is located on the anti-gable side of the central position. The first side wall portion 301 constitutes the side wall on the wife side of the climbing tree member 3, and the second side wall portion 303 constitutes the side wall on the opposite side of the climbing tree member 3.
　のぼり木部材３を緊結するための緊結部材７は、上壁部３０２の上方から上壁部３０２、第２下壁部３０４及び野地板１を貫通するように垂木部材４に打ち込まれる。すなわち、緊結部材７は、幅方向３ａに係るのぼり木部材３の下部の中央位置よりも妻側端部から離れた位置で野地板１を貫通する。このように緊結部材７が打ち込まれることで、野地板１の妻側端部が破損する虞を低減できる。但し、状況によっては、上壁部３０２及び第１下壁部３００を貫通するようにのぼり木部材３に緊結部材７を打ち込んでのぼり木部材３を緊結してもよい。また、第１及び第２下壁部３００，３０４の両方をそれぞれ貫通するようにのぼり木部材３に緊結部材７を打ち込んでもよい。 The binding member 7 for binding the climbing tree member 3 is driven into the rafter member 4 from above the upper wall portion 302 so as to penetrate the upper wall portion 302, the second lower wall portion 304, and the field board 1. That is, the binding member 7 penetrates the field board 1 at a position farther from the end on the gable side than the central position of the lower part of the climbing tree member 3 in the width direction 3a. By driving the binding member 7 in this way, it is possible to reduce the possibility that the end portion of the field plate 1 on the end side is damaged. However, depending on the situation, the binding member 7 may be driven into the climbing tree member 3 so as to penetrate the upper wall portion 302 and the first lower wall portion 300 to bind the climbing tree member 3. Further, the binding member 7 may be driven into the climbing tree member 3 so as to penetrate both the first and second lower wall portions 300 and 304, respectively.
　ケラバ部材６２を緊結するための緊結部材７は、第１側壁部３０１を貫通してのぼり木部材３の内側に進入している。第１側壁部３０１の内側には、緊結部材７を取り囲むように打ち抜きバリ３０１ａが形成されている。打ち抜きバリ３０１ａは、緊結部材７に絡みつき緊結部材７の引き抜きを阻害する。 The binding member 7 for binding the keraba member 62 penetrates the first side wall portion 301 and enters the inside of the climbing tree member 3. A punching burr 301a is formed inside the first side wall portion 301 so as to surround the binding member 7. The punching burr 301a is entangled with the binding member 7 and hinders the pulling out of the binding member 7.
　鍔部３１の下方には屋根材２の端部が収められる。すなわち、本実施の形態の屋根構造を鉛直方向上方から見たとき、鍔部３１が屋根材２の端部を覆っている。また、図１に示すようにのぼり木部材３、水切部材６１及びケラバ部材６２が配置された際に、後述の水切部材６１の第１斜片６１２とケラバ部材６２の天板６２０との間の空間に鍔部３１が進入されている。鍔部３１は、例えば作業員の踏み潰し及び飛来物の衝突等の外力によって屋根材２の端部、水切部材６１及びケラバ部材６２が破損する虞を低減できる。 The end of the roofing material 2 is housed below the collar 31. That is, when the roof structure of the present embodiment is viewed from above in the vertical direction, the flange portion 31 covers the end portion of the roofing material 2. Further, as shown in FIG. 1, when the climbing tree member 3, the drainage member 61 and the keraba member 62 are arranged, between the first oblique piece 612 of the drainage member 61 and the top plate 620 of the keraba member 62, which will be described later. The collar 31 has entered the space. The collar portion 31 can reduce the possibility that the end portion of the roofing material 2, the draining member 61, and the keraba member 62 are damaged by an external force such as a worker trampling or a collision of a flying object.
　なお、のぼり木部材３が必ず金属板の成形体でなければならないわけでなく、図３に示す外形を有する木材又は他の材料によりのぼり木部材３が構成されてもよい。木材又は他の材料によりのぼり木部材３を構成しても、鍔部３１が設けられていることにより、屋根材２の端部等が破損する虞を低減できる。木材又は他の材料によりのぼり木部材３を構成するとき、のぼり木部材３は中実構造であってもよい。すなわち、のぼり木部材３の内部が空洞でなくてもよい。 Note that the climbing wood member 3 does not necessarily have to be a molded body of a metal plate, and the climbing wood member 3 may be made of wood or other material having an outer shape shown in FIG. Even if the climbing wood member 3 is made of wood or other material, the possibility that the end portion of the roofing material 2 or the like is damaged can be reduced because the flange portion 31 is provided. When the climbing wood member 3 is made of wood or other material, the climbing wood member 3 may have a solid structure. That is, the inside of the climbing tree member 3 does not have to be hollow.
＜水切部材について＞

Next, the keraba member 62 will be described with reference to FIGS. 6 and 1. FIG. 6 is a perspective view showing the keraba member 62 of FIG. As shown in FIG. 6, the keraba member 62 of the present embodiment has a top plate 620, a hanging piece 621, a second oblique piece 622, and a second folded piece 623. The keraba member 62 of the present embodiment is a molded body of a metal plate. Specifically, the keraba member 62 is formed by bending a metal plate. The above-mentioned top plate 620, hanging piece 621, second oblique piece 622, and second folded piece 623 are integrally formed with each other.
　天板６２０は、ケラバ部材６２の上部においてケラバ部材６２の幅方向６２ａに延在された板状部分である。本実施の形態の天板６２０は平板状に形成されているが、凹凸状のリブが天板６２０に形成されていてもよい。図１に示すように、天板６２０は、のぼり木部材３の上壁部３０２に重ねられる。幅方向６２ａに係る天板６２０の延在幅は、のぼり木部材３の上壁部３０２の延在幅よりも長い。 The top plate 620 is a plate-like portion extending in the width direction 62a of the keraba member 62 at the upper part of the keraba member 62. Although the top plate 620 of the present embodiment is formed in a flat plate shape, uneven ribs may be formed in the top plate 620. As shown in FIG. 1, the top plate 620 is overlapped with the upper wall portion 302 of the climbing tree member 3. The extending width of the top plate 620 in the width direction 62a is longer than the extending width of the upper wall portion 302 of the climbing tree member 3.
　下垂片６２１は、幅方向６２ａに係る天板６２０の一端から下方に向けて延出された壁部である。ケラバ部材６２の高さ方向６２ｂに係る下垂片６２１の延在幅は、図１に示すように天板６２０がのぼり木部材３の上壁部３０２に重ねられた際に下垂片６２１の下端が破風板５の側方に達するように設定することができる。下垂片６２１の下端には、下垂片６２１を構成する金属板が下垂片６２１の内側に１８０°折り返された端部折返部６２１ａが設けられている。端部折返部６２１ａは、破風板５と下垂片６２１との間に隙間を形成する。 The hanging piece 621 is a wall portion extending downward from one end of the top plate 620 in the width direction 62a. As shown in FIG. 1, the extending width of the hanging piece 621 related to the height direction 62b of the keraba member 62 is such that when the top plate 620 is overlapped with the upper wall portion 302 of the climbing tree member 3, the lower end of the hanging piece 621 is It can be set to reach the side of the gable plate 5. At the lower end of the hanging piece 621, an end folded portion 621a in which a metal plate constituting the hanging piece 621 is folded back 180 ° inside the hanging piece 621 is provided. The end folded portion 621a forms a gap between the gable plate 5 and the hanging piece 621.
　天板６２０と下垂片６２１との間の角度は、９０°より大きくかつ１００°以下であることが好ましい。９０°より大きいことで、図１のようにケラバ部材６２を配置する際に下垂片６２１の下端とのぼり木部材３の上壁部３０２とが干渉する虞を低減できる。また、１００°以下であることで、緊結部材７により下垂片６２１をのぼり木部材３に緊結した後に下垂片６２１とのぼり木部材３との間に不必要な隙間が生じる虞を低減できる。天板６２０と下垂片６２１との間の角度は９５°以下であることがより好ましい。本実施の形態では、天板６２０と下垂片６２１との間の角度は９３°とされている。 The angle between the top plate 620 and the hanging piece 621 is preferably larger than 90 ° and 100 ° or less. When the temperature is larger than 90 °, it is possible to reduce the possibility that the lower end of the hanging piece 621 and the upper wall portion 302 of the climbing tree member 3 interfere with each other when the keraba member 62 is arranged as shown in FIG. Further, when the temperature is 100 ° or less, it is possible to reduce the possibility that an unnecessary gap is generated between the hanging piece 621 and the climbing tree member 3 after the hanging piece 621 is fastened to the climbing tree member 3 by the binding member 7. More preferably, the angle between the top plate 620 and the hanging piece 621 is 95 ° or less. In the present embodiment, the angle between the top plate 620 and the hanging piece 621 is 93 °.
　第２斜片６２２は、幅方向６２ａに係る天板６２０の他端から下方に延在されるとともに、幅方向６２ａに関して下垂片６２１に近づく方向に延在された壁部である。第２斜片６２２は、ケラバ部材６２の高さ方向６２ｂに対して傾斜して延在されている。天板６２０と第２斜片６２２との間の角度は、図１に示すように水切部材６１及びケラバ部材６２が配置された際に第２斜片６２２の先端が水切部材６１の第１斜片６１２の下方に位置できるように、のぼり木部材３の延長壁部３１０と接続壁部３１１との間の角度よりも大きく設定される。本実施の形態では、天板６２０と第２斜片６２２との間の角度が４３°に設定されている。 The second oblique piece 622 is a wall portion extending downward from the other end of the top plate 620 in the width direction 62a and extending in a direction approaching the hanging piece 621 in the width direction 62a. The second oblique piece 622 is inclined and extends with respect to the height direction 62b of the keraba member 62. As for the angle between the top plate 620 and the second oblique piece 622, the tip of the second oblique piece 622 is the first oblique member 61 when the drain member 61 and the keraba member 62 are arranged as shown in FIG. It is set to be larger than the angle between the extension wall portion 310 and the connection wall portion 311 of the climbing tree member 3 so that it can be located below the piece 612. In the present embodiment, the angle between the top plate 620 and the second oblique piece 622 is set to 43 °.
　第２折返片６２３は、第２斜片６２２の先端から上方かつ第２斜片６２２の基端に近づくように折り返された壁部である。 The second folded piece 623 is a wall portion that is folded upward from the tip of the second oblique piece 622 and close to the base end of the second oblique piece 622.
　水切部材６１及びケラバ部材６２は、図１に示すようにのぼり木部材３の第２側壁部３０３（反妻側の側壁部）を覆うように水切部材６１が配置されるとともに、のぼり木部材３の第１側壁部３０１（妻側の側壁部）及び上壁部３０２を覆うようにケラバ部材６２が配置されたとき、第１及び第２折返片６１３，６２３が互いに係合されるように構成されている。換言すると、水切部材６１及びケラバ部材６２は、図１に示すように水切部材６１及びケラバ部材６２が配置された際に第２折返片６２３の先端が第１折返片６１３の先端よりも軒側かつ上方に位置し、反妻側への第２斜片６２２の変位を第１及び第２折返片６１３，６２３が規制するように構成されている。このような構成は、例えば第１斜片６１２と第１折返片６１３との間の角度及び第１折返片６１３の延在幅、並びに第２斜片６２２と第２折返片６２３との間の角度及び第２折返片６２３の延在幅等の設定により実現可能である。 As shown in FIG. 1, the drainage member 61 and the keraba member 62 are arranged so as to cover the second side wall portion 303 (the side wall portion on the anti-gable side) of the climbing tree member 3, and the climbing tree member 3 is arranged. When the keraba member 62 is arranged so as to cover the first side wall portion 301 (the side wall portion on the gable side) and the upper wall portion 302, the first and second folded pieces 613 and 623 are configured to be engaged with each other. Has been done. In other words, in the drainage member 61 and the keraba member 62, when the drainage member 61 and the keraba member 62 are arranged, the tip of the second folding piece 623 is closer to the eaves side than the tip of the first folding piece 613. Moreover, it is located above and is configured so that the first and second folded pieces 613 and 623 regulate the displacement of the second oblique piece 622 toward the anti-gable side. Such a configuration is, for example, the angle between the first oblique piece 612 and the first folded piece 613 and the extending width of the first folded piece 613, and between the second oblique piece 622 and the second folded piece 623. This can be achieved by setting the angle and the extending width of the second folded piece 623.
　水切部材６１及びケラバ部材６２は、図１に示すように水切部材６１及びケラバ部材６２が配置された際に第２折返片６２３の先端が水切部材６１の第１斜片６１２の下面に当接されるように構成されていることが好ましい。 In the drainage member 61 and the keraba member 62, when the drainage member 61 and the keraba member 62 are arranged, the tip of the second folded piece 623 comes into contact with the lower surface of the first oblique piece 612 of the drainage member 61. It is preferable that it is configured to be.
　次に、図７は、図１のケラバ部材６２の配置方法を示す説明図である。図７において、（ａ）はケラバ部材６２の配置開始直後の状態を示し、（ｂ）はケラバ部材６２の配置途中の状態を示し、（ｃ）はケラバ部材６２の配置完了の状態を示している。（ａ）に示すように、緊結部材７によりのぼり木部材３を緊結するとともに水切部材６１及び屋根材２を配置した後に、ケラバ部材６２の配置を開始する。ケラバ部材６２は、のぼり木部材３の鍔部３１及び水切部材６１の第１斜片６１２の下方に第２斜片６２２の先端を潜り込ませた状態で、図中の矢印Ａのようにケラバ部材６２全体を回動させてのぼり木部材３の上壁部３０２に天板６２０を重ねつつ、図中左側の妻側にケラバ部材６２全体をスライドさせる。 Next, FIG. 7 is an explanatory diagram showing a method of arranging the keraba member 62 of FIG. In FIG. 7, (a) shows a state immediately after the start of arrangement of the keraba member 62, (b) shows a state in the middle of arranging the keraba member 62, and (c) shows a state in which the arrangement of the keraba member 62 is completed. There is. As shown in (a), after the climbing lumber member 3 is tied by the binding member 7 and the draining member 61 and the roofing material 2 are arranged, the arrangement of the keraba member 62 is started. The keraba member 62 is a keraba member as shown by an arrow A in the drawing, with the tip of the second oblique piece 622 slipping under the flange portion 31 of the climbing tree member 3 and the first oblique piece 612 of the drainage member 61. While rotating the entire 62 and superimposing the top plate 620 on the upper wall portion 302 of the climbing tree member 3, the entire keraba member 62 is slid to the gable side on the left side in the drawing.
　このとき、（ｂ）に示すように、水切部材６１の第１折返片６１３とケラバ部材６２の第２折返片６２３との接触によって、ケラバ部材６２の天板６２０と第２斜片６２２との間が弾性変形により押し広げられながら、第２折返片６２３が第１折返片６１３を乗り越えていく。 At this time, as shown in (b), the contact between the first folded piece 613 of the drainage member 61 and the second folded piece 623 of the keraba member 62 causes the top plate 620 of the keraba member 62 and the second oblique piece 622 to come into contact with each other. The second folded piece 623 gets over the first folded piece 613 while the space is expanded by the elastic deformation.
　本実施の形態の態様では、第２折返片６２３が第１折返片６１３を乗り越えたとき、第２折返片６２３の先端が第１斜片６１２の先端に当接する。この当接時に「カチ」という装着音が発生する。この装着音により、第２折返片６２３が第１折返片６１３を乗り越えて、第１及び第２折返片６１３，６２３が互いに係合したことを作業員が明確に認識できる。 In the embodiment of the present embodiment, when the second folded piece 623 gets over the first folded piece 613, the tip of the second folded piece 623 comes into contact with the tip of the first oblique piece 612. At the time of this contact, a clicking sound is generated. By this mounting sound, the worker can clearly recognize that the second folded piece 623 has passed over the first folded piece 613 and the first and second folded pieces 613 and 623 are engaged with each other.
　第２折返片６２３が第１折返片６１３を乗り越えた後、妻側から下垂片６２１に緊結部材７を打ち込み、ケラバ部材６２をのぼり木部材３に緊結する。 After the second folded piece 623 gets over the first folded piece 613, the binding member 7 is driven into the hanging piece 621 from the gable side, and the keraba member 62 is bound to the climbing wood member 3.
　このような屋根構造及びケラバ水切役物６では、第１及び第２折返片６１３，６２３が互いに係合されるように水切部材６１及びケラバ部材６２が構成されているので、仮に緊結部材７によるケラバ部材６２の緊結が弱まったとしても第１及び第２折返片６１３，６２３の係合によりケラバ部材６２の反妻側への変位を規制でき、強風によりケラバ部材が吹き飛ばされる虞を低減できる。 In such a roof structure and the keraba drainage accessory 6, the drainage member 61 and the keraba member 62 are configured so that the first and second folded pieces 613 and 623 are engaged with each other. Even if the tightness of the keraba member 62 is weakened, the displacement of the keraba member 62 to the opposite side can be regulated by the engagement of the first and second folded pieces 613 and 623, and the possibility that the keraba member is blown off by a strong wind can be reduced.
　また、水切部材６１を配置した後にケラバ部材６２を配置する際に、第２折返片６２３が第１折返片６１３を乗り越えるとき、第２折返片６２３の先端が第１斜片６１２の下面に当接されるように、水切部材６１及びケラバ部材６２が構成されているので、第２折返片６２３の先端が第１斜片６１２の先端に当接した際に「カチ」という装着音を発生させることができ、この装着音により、第２折返片６２３が第１折返片６１３を乗り越えて、第１及び第２折返片６１３，６２３が互いに係合したことを作業員が明確に認識できる。また、より確実に第１及び第２折返片６１３，６２３を互いに係合できる。 Further, when the keraba member 62 is arranged after the drain member 61 is arranged, when the second folded piece 623 gets over the first folded piece 613, the tip of the second folded piece 623 hits the lower surface of the first oblique piece 612. Since the drain member 61 and the keraba member 62 are configured so as to be in contact with each other, a clicking sound is generated when the tip of the second folded piece 623 comes into contact with the tip of the first oblique piece 612. This mounting sound allows the operator to clearly recognize that the second folded piece 623 has passed over the first folded piece 613 and the first and second folded pieces 613 and 623 are engaged with each other. Further, the first and second folded pieces 613 and 623 can be more reliably engaged with each other.
　さらに、のぼり木部材本体３０からのぼり木部材３の幅方向３ａに係る外方に突出された鍔部３１が、水切部材６１の第１斜片６１２とケラバ部材６２の天板６２０との間の空間に進入されるので、例えば作業員の踏み潰し及び飛来物の衝突等の外力によって屋根材の端部、水切部材及びケラバ部材が破損する虞を低減できる。 Further, the flange portion 31 protruding outward from the climbing tree member main body 30 in the width direction 3a of the climbing tree member 3 is between the first oblique piece 612 of the drainage member 61 and the top plate 620 of the keraba member 62. Since it enters the space, it is possible to reduce the possibility that the edge of the roofing material, the drainage member, and the keraba member are damaged by an external force such as a worker trampling or a collision of a flying object.
　さらにまた、のぼり木部材３が金属板の成形体であるので、のぼり木部材３が木材によって構成される場合と比較して、のぼり木部材３の劣化により緊結部材７によるケラバ部材６２の緊結が弱まる虞を低減できる。 Furthermore, since the climbing wood member 3 is a molded body of a metal plate, the keraba member 62 is bound by the binding member 7 due to the deterioration of the climbing wood member 3 as compared with the case where the climbing wood member 3 is made of wood. The risk of weakening can be reduced.

At this time, the third side wall portion 307 is located on the side of the field plate 1 and the gable plate 5. The binding member 7 can be driven from the outside of the hanging piece 621 toward the gable plate 5 so as to penetrate the hanging piece 621, the third side wall portion 307, and the gable plate 5 of the keraba member 62. As a result, the keraba member 62 and the climbing tree member 3 can be fixed to the gable board 5.
　また、第２下壁部３０４を貫通するように第２下壁部３０４の上方から野地板１に向かって緊結部材７を打ち込むことができる。これにより、のぼり木部材３を野地板１に固定することができる。その他の構成は、実施の形態１と同様である。 Further, the binding member 7 can be driven from above the second lower wall portion 304 toward the field plate 1 so as to penetrate the second lower wall portion 304. As a result, the climbing tree member 3 can be fixed to the field board 1. Other configurations are the same as those in the first embodiment.
　図１０は、図８の屋根構造の変形例を示す説明図である。図１０に示すように、実施の形態２ののぼり木部材３を、第１折返片６１３を有しない水切部材６１及び第２折返片６２３を有しないケラバ部材６２と組み合わせて使用してもよい。 FIG. 10 is an explanatory view showing a modified example of the roof structure of FIG. As shown in FIG. 10, the climbing tree member 3 of the second embodiment may be used in combination with the drainage member 61 having no first folded piece 613 and the keraba member 62 having no second folded piece 623.
