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. ..

<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.

 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.

 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>
 次に、図5及び図1を参照しながら水切部材61について説明する。図5は、図1の水切部材61を示す斜視図である。図5に示すように、本実施の形態の水切部材61は、載置片610、起立片611、第1斜片612及び第1折返片613を有している。本実施の形態の水切部材61は、金属板の成形体である。具体的には、水切部材61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。上述の載置片610、起立片611、第1斜片612及び第1折返片613は互いに一体に形成されている。
<About drainage members>
Next, the drainage member 61 will be described with reference to FIGS. 5 and 1. FIG. 5 is a perspective view showing the drainage member 61 of FIG. As shown in FIG. 5, the drainage member 61 of the present embodiment has a mounting piece 610, an upright piece 611, a first oblique piece 612, and a first folded piece 613. The drainage member 61 of the present embodiment is a molded body of a metal plate. Specifically, the drainage member 61 is formed by bending a metal plate. The above-mentioned mounting piece 610, standing piece 611, first oblique piece 612, and first folded piece 613 are integrally formed with each other.
 載置片610は、水切部材61の下部において水切部材61の幅方向61aに延在する板状部分である。本実施の形態の載置片610は平板状に形成されているが、凹凸状のリブが載置片610に形成されていてもよい。幅方向61aに係る載置片610の一端には、載置片610を構成する金属板が載置片610の上面側に180°折り返された端部折返部610aが設けられている。図1に示すように、載置片610は野地板上に載置される部分である。端部折返部610aが設けられた載置片610の一端は、幅方向61aに係る載置片610の他端よりも屋根の妻側端部から離れた位置(反妻側)に配置される。載置片610の他端は、載置片610の反妻側端部を構成する。端部折返部610aは、載置片610の上面に載せられた屋根材2と載置片610との間に隙間を形成する。 The mounting piece 610 is a plate-shaped portion extending in the width direction 61a of the drainage member 61 at the lower portion of the drainage member 61. Although the mounting piece 610 of the present embodiment is formed in a flat plate shape, uneven ribs may be formed in the mounting piece 610. At one end of the mounting piece 610 related to the width direction 61a, an end folded portion 610a in which a metal plate constituting the mounting piece 610 is folded back by 180 ° on the upper surface side of the mounting piece 610 is provided. As shown in FIG. 1, the mounting piece 610 is a portion to be mounted on the field board. One end of the mounting piece 610 provided with the end folding portion 610a is arranged at a position (anti-gable side) away from the end of the roof on the end side of the mounting piece 610 in the width direction 61a. .. The other end of the mounting piece 610 constitutes the opposite end of the mounting piece 610. The end folded portion 610a forms a gap between the roofing material 2 mounted on the upper surface of the mounting piece 610 and the mounting piece 610.
 起立片611は、幅方向61aに係る載置片610の他端から起立された壁部であり、のぼり木部材3の第2側壁部303(反妻側の側壁部)に沿わされる。載置片610と起立片611との間の角度は、のぼり木部材3の第2側壁部303と第2下壁部304との間の角度に基づいて決定することができる。本実施の形態では、載置片610と起立片611との間の角度は90°に設定されている。水切部材61の高さ方向61bに係る起立片611の延在幅は、のぼり木部材3の第2側壁部303の延在幅よりも短く設定されている。 The standing piece 611 is a wall portion that stands up from the other end of the mounting piece 610 in the width direction 61a, and is along the second side wall portion 303 (the side wall portion on the anti-gable side) of the climbing tree member 3. The angle between the mounting piece 610 and the standing piece 611 can be determined based on the angle between the second side wall portion 303 and the second lower wall portion 304 of the climbing tree member 3. In the present embodiment, the angle between the mounting piece 610 and the standing piece 611 is set to 90 °. The extending width of the standing piece 611 related to the height direction 61b of the draining member 61 is set shorter than the extending width of the second side wall portion 303 of the climbing tree member 3.
 第1斜片612は、起立片611の上端から上方に延在されるとともに、幅方向61aに関して載置片610の反妻側端部(端部折返部610aが設けられた載置片610の一端)に近づく方向に延在された壁部である。第1斜片612は、水切部材61の高さ方向61bに対して傾斜して延在されている。起立片611と第1斜片612との間の角度は、のぼり木部材3の接続壁部311に第1斜片612が沿うように、のぼり木部材3の接続壁部311と第2側壁部303との間の角度に基づいて決定することができる。本実施の形態では、起立片611と第1斜片612との間の角度は110°とされている。第1斜片612の延在幅は、のぼり木部材3の鍔部31(接続壁部311)の延在幅よりも短く設定されることが好ましい。すなわち、第1斜片612の先端が鍔部31から突出しないように第1斜片612の延在幅が設定されることが好ましい。 The first oblique piece 612 extends upward from the upper end of the standing piece 611, and the mounting piece 610 provided with the counter-gable side end portion (end folding portion 610a) of the mounting piece 610 in the width direction 61a. It is a wall part extending in the direction approaching (one end). The first oblique piece 612 is inclined and extends with respect to the height direction 61b of the drainage member 61. The angle between the standing piece 611 and the first oblique piece 612 is such that the first oblique piece 612 follows the connecting wall portion 311 of the climbing tree member 3, and the connecting wall portion 311 and the second side wall portion of the climbing tree member 3. It can be determined based on the angle with and from 303. In the present embodiment, the angle between the standing piece 611 and the first oblique piece 612 is 110 °. The extending width of the first oblique piece 612 is preferably set shorter than the extending width of the flange portion 31 (connecting wall portion 311) of the climbing tree member 3. That is, it is preferable that the extending width of the first oblique piece 612 is set so that the tip of the first oblique piece 612 does not protrude from the collar portion 31.
 第1折返片613は、第1斜片612の先端から下方かつ第1斜片612の基端に近づく方向に折り返された壁部である。第1斜片612と第1折返片613との間の角度は、鋭角とされている。本実施の形態では、第1斜片612と第1折返片613との間の角度が20°とされている。第1斜片612の延在幅は、接続壁部311の延在幅の40~70%であることが好ましい。 The first folded piece 613 is a wall portion folded downward from the tip of the first oblique piece 612 and closer to the base end of the first oblique piece 612. The angle between the first oblique piece 612 and the first folded piece 613 is an acute angle. In the present embodiment, the angle between the first oblique piece 612 and the first folded piece 613 is set to 20 °. The extending width of the first oblique piece 612 is preferably 40 to 70% of the extending width of the connecting wall portion 311.
<ケラバ部材について>
 次に、図6及び図1を参照しながら、ケラバ部材62について説明する。図6は、図1のケラバ部材62を示す斜視図である。図6に示すように、本実施の形態のケラバ部材62は、天板620、下垂片621、第2斜片622及び第2折返片623を有している。本実施の形態のケラバ部材62は、金属板の成形体である。具体的には、ケラバ部材62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。上述の天板620、下垂片621、第2斜片622及び第2折返片623は互いに一体に形成されている。

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.
