JP-A-8-49289 (paragraph numbers 0002 and 0003, FIG. 9)

建物外壁とバルコニ床との間を防水するためには、この特許文献１のように、建物外壁に沿って延びる水切り部材により建物外壁とバルコニ床との間を防水しただけでもよいが、雨水等の水が建物外壁とバルコニ床との間に侵入するのを一層確実に防止することができ、その防水性を向上させることが望まれる。 In order to waterproof between the building outer wall and the balcony floor, as in Patent Document 1, it is only necessary to waterproof between the building outer wall and the balcony floor by a draining member extending along the building outer wall. It is desirable to further prevent water from entering between the outer wall of the building and the balconi floor, and to improve its waterproofness.

本発明の目的は、建物外壁とバルコニ床との間の防水シール性を向上させることができるバルコニの水切り構造を提供するところにある。 The objective of this invention is providing the draining structure of the balconi which can improve the waterproof sealing property between a building outer wall and a balcony floor.

本発明に係るバルコニの水切り構造は、バルコニが設けられている建物外壁とバルコニ床との間が、前記建物外壁に沿って延びる水切り部材によって防水されるバルコニの水切り構造において、前記バルコニ床はデッキ部材で形成され、このデッキ部材には、前記水切り部材の先端よりも前記建物外壁側において、上向きに開口した溝が形成されていることを特徴とするものである。 The balconi draining structure according to the present invention is a balconi draining structure in which a space between a building outer wall provided with the balconi and a balcony floor is waterproofed by a draining member extending along the outer wall of the building. The deck member is formed with a groove that opens upward on the outer wall side of the building from the tip of the draining member.

このバルコニの水切り構造によると、バルコニ床を形成しているデッキ部材には、水切り部材の先端よりも建物外壁側の部分において、上向きに開口した溝が形成されているため、水切り部材の先端よりも建物外壁側へ雨水等の水が侵入しても、この水は溝に落下することになる。このため、建物外壁とバルコニ床との間の防水性は向上する。 According to this balconi draining structure, the deck member that forms the balconi floor has a groove that opens upward in the portion on the outer wall side of the building relative to the tip of the drainer member. However, even if water such as rainwater enters the building outer wall, this water will fall into the groove. For this reason, the waterproofness between a building outer wall and a balcony floor improves.

このようにデッキ部材に、水切り部材の先端よりも建物外壁側において、上向きに開口した溝を形成する場合において、水切り部材の全部又は一部はデッキ部材の上面と接触していてもよく、接触していなくてもよい。 In this way, in the case where the deck member is formed with a groove that opens upward on the building outer wall side than the tip of the draining member, all or a part of the draining member may be in contact with the upper surface of the deck member. You don't have to.

水切り部材の一部がデッキ部材の上面と接触している場合には、この接触箇所よりも建物外壁側のデッキ部材の部分に溝を形成する。これによると、水切り部材の一部が接触しているデッキ部材の上面の箇所から雨水等の水が建物外壁側へ侵入しても、この水を溝に落下させることができる。 When a part of the draining member is in contact with the upper surface of the deck member, a groove is formed in the portion of the deck member closer to the building outer wall than the contact point. According to this, even if water such as rainwater enters the building outer wall side from the position on the upper surface of the deck member with which a part of the draining member is in contact, the water can be dropped into the groove.

デッキ部材に形成する上記溝は、建物外壁に沿って一定長さ延びるものとなっていてその両端部は閉塞されていてもよく、また、建物外壁に沿って延びるこの溝の長さ方向の少なくとも一方の端部はデッキ部材の端部の位置で開口していてもよい。溝が後者である場合には、デッキ部材の下方に、この溝の開口端部から流下する水を受ける樋部材を配置することが好ましい。 The groove formed in the deck member extends a certain length along the outer wall of the building, and both ends thereof may be closed, and at least in the length direction of the groove extending along the outer wall of the building. One end may be opened at the position of the end of the deck member. When the groove is the latter, it is preferable to dispose a dredging member that receives water flowing down from the opening end of the groove below the deck member.

これによると、水切り部材の先端よりも建物外壁側へ侵入した雨水等の水が上記溝に落下した場合、この水は溝を経て樋部材に達することになり、これにより、この樋部材から又はこの樋部材に接続されている別の樋部材から水をバルコニの外部に排出することができる。 According to this, when water such as rain water that has entered the building outer wall side from the front end of the draining member falls into the groove, the water reaches the dredging member through the groove, and from this dredging member or Water can be discharged to the outside of the balconi from another heel member connected to the heel member.

また、水切り部材の形状や、水切り部材とデッキ部材の建物外壁側の端部との関係等は任意である。その一例は、水切り部材に、デッキ部材の建物外壁側の端部とこの建物外壁との間において、上下に延びる上下延出部を設け、この上下延出部と、デッキ部材の建物外壁側の端部との間に、水切り部材とデッキ部材との間を防水シールする防水部材を介設することである。 The shape of the draining member, the relationship between the draining member and the end of the deck member on the building outer wall side, and the like are arbitrary. For example, the draining member is provided with a vertically extending portion extending vertically between the end of the deck member on the building outer wall side and the building outer wall, and the vertically extending portion and the deck member on the building outer wall side. Between the end portions, a waterproof member for waterproof sealing between the draining member and the deck member is interposed.

これによると、たとえ、前記溝に落下した水がこの溝を越えることがあっても、この水が水切り部材の上下延出部とデッキ部材との間に侵入することが上記防水部材で阻止され、水切り部材の上下延出部とデッキ部材との間から漏水することが防止される。 According to this, even if the water dropped into the groove may cross the groove, the waterproof member prevents the water from entering between the vertically extending portion of the draining member and the deck member. Further, it is possible to prevent water from leaking from between the upper and lower extending portions of the draining member and the deck member.

上述のように、水切り部材の上下延出部とデッキ部材の建物外壁側の端部との間に防水部材を介設する場合には、この防水部材は、デッキ部材が水切り部材に対して配置される際に、水切り部材の上下延出部とデッキ部材の建物外壁側の端部との間に介設されてもよく、あるいは、この防水部材を予め水切り部材の上下延出部に取り付けておき、デッキ部材を水切り部材に対して配置することにより、防水部材が上下延出部とデッキ部材の建物外壁側の端部との間で圧縮変形されるようにしてもよい。 As described above, when a waterproof member is interposed between the vertically extending portion of the draining member and the end of the deck member on the building outer wall side, the waterproof member is arranged with respect to the draining member. When this is done, it may be interposed between the vertically extending portion of the draining member and the end of the deck member on the building outer wall side, or the waterproof member is attached to the vertically extending portion of the draining member in advance. The waterproof member may be compressed and deformed between the vertically extending portion and the end portion of the deck member on the building outer wall side by disposing the deck member with respect to the draining member.

後者によると、防水部材は予め水切り部材の上下延出部に取り付けられているため、防水部材を水切り部材の上下延出部とデッキ部材の建物外壁側の端部との間に介設するための作業を容易に行えるとともに、この防水部材は、水切り部材の上下延出部とデッキ部材の建物外壁側の端部との間に圧縮変形して配置されるため、その防水機能を向上させることができる。 According to the latter, since the waterproof member is previously attached to the vertically extending portion of the draining member, the waterproof member is interposed between the vertically extending portion of the draining member and the end of the deck member on the building outer wall side. This waterproof member can be compressed and deformed between the vertically extending portion of the draining member and the end of the deck member on the building outer wall side, so that its waterproof function can be improved. Can do.

このように防水部材を圧縮変形自在性を有するものとするためには、防水部材を、例えば、軟質の多孔質材料等で形成すればよい。また、防水部材を予め水切り部材の上下延出部に取り付けておくためには、ビス等の止着具や、接着剤や両面粘着テープ等を用いればよい。 Thus, in order to make the waterproof member have compressibility, the waterproof member may be formed of, for example, a soft porous material. Moreover, in order to attach the waterproof member to the vertically extending portion of the draining member in advance, a fastening tool such as a screw, an adhesive, a double-sided adhesive tape, or the like may be used.

本発明において、バルコニが設けられている建物外壁とバルコニ床との間を防水するための水切り部材は、任意な箇所に取り付けることができ、その一例は、水切り部材を、デッキ部材が載せられるバルコニの根太に取り付けることであり、他の例は、水切り部材を建物外壁に取り付けることである。 In the present invention, the draining member for waterproofing between the outer wall of the building where the balconi is provided and the balcony floor can be attached to an arbitrary place. For example, the draining member is a balconi on which the deck member is placed. The other example is attaching a draining member to the building outer wall.

また、この水切り部材と建物外壁との間の防水性も、任意な手段で確保することができる。その一例は、水切り部材と建物外壁との間に、これらの水切り部材と建物外壁とで挟着させて防水部材を介設することであり、他の例は、水切り部材に建物外壁側へ延びる防水部材受け部を設け、この防水部材受け部に、水切り部材と建物外壁との間を防水シールする防水部材を配置することである。 Moreover, the waterproofness between this draining member and a building outer wall can also be ensured by arbitrary means. One example is that a water proofing member is interposed between the water draining member and the building outer wall, and the water draining member is interposed between the water draining member and the building outer wall. In another example, the water draining member extends to the building outer wall side. A waterproof member receiving portion is provided, and a waterproof member for waterproof sealing between the draining member and the building outer wall is disposed in the waterproof member receiving portion.

後者によると、防水部材は、防水部材受け部によって受けられながら水切り部材と建物外壁との間に配置されるため、防水部材の脱落等を防止してその配置を行えることになる。この防水部材は、湿式タイプのものでもよく、乾式タイプのものでもよい。 According to the latter, since the waterproof member is disposed between the draining member and the building outer wall while being received by the waterproof member receiving portion, the waterproof member can be disposed while preventing the waterproof member from dropping off. This waterproof member may be a wet type or a dry type.

以上の本発明は、住宅等の建物に後付け作業で付設されるバルコニにも適用でき、建物の建築と同時に一体施工されるバルコニにも適用できる。また、本発明は、支柱で支持されないバルコニと支柱で支持されるバルコニの両方に適用できる。 The present invention described above can also be applied to a balconi attached to a building such as a house by retrofitting work, and can also be applied to a balconi that is integrally constructed at the same time as building construction. Further, the present invention can be applied to both a balconi that is not supported by a support and a balconi that is supported by a support.

As shown in FIG. 6, before the deck member 26 is placed on the joist 22, in other words, the deck member 26 is attached to the draining member 31 attached to the joist 22 with a fastening device 79. Before being disposed, a waterproof member 72 is attached in advance to the front surface of the vertically extending portion 70 A of the draining member 31. This attachment is performed, for example, in a factory before the draining member 31 is shipped to the balcony construction site, or before an operation of placing the deck member 26 with respect to the draining member 31 at the balcony construction site.

水切り部材３１の下部前方延出部７０Ｃを根太２２の上に載せ、この下部前方延出部７０Ｃを止着具７９で根太２２に取り付けた後、図５で示されているように、デッキ部材２６を根太２２の上に前記止着具２９で取付配置する作業が行われ、この作業により、防水部材７２は、デッキ部材２６の後端部７４と住宅の外壁２との間に配置されている水切り部材３１の上下延出部７０Ａと、デッキ部材２６の後端部７４とにより挟着されるため、防水部材７２は圧縮変形することにより、これらの水切り部材３１の上下延出部７０Ａと、デッキ部材２６の後端部７４との間を防水シールする。 After the lower front extending portion 70C of the draining member 31 is placed on the joist 22 and this lower front extending portion 70C is attached to the joist 22 with the fastening device 79, as shown in FIG. 26 is mounted on the joist 22 with the fastening device 29, and the waterproof member 72 is disposed between the rear end portion 74 of the deck member 26 and the outer wall 2 of the house. Since the waterproof member 72 is compressed and deformed, the vertically extending portion 70A of the draining member 31 and the rear end portion 74 of the deck member 26 are compressed. The space between the rear end 74 of the deck member 26 is waterproof.

また、水切り部材３１を止着具７９で根太２２に取り付ける作業は、水切り部材３１の防水部材受け部７０Ｄを住宅の外壁２に当接させて行われ、止着具７９による水切り部材３１の根太２２への取付作業後、防水部材受け部７０Ｄの上に湿式の防水部材８０を充填する作業が行われ、防水部材受け部７０Ｄで受けられて乾燥固化するこの防水部材８０により、水切り部材３１と住宅の外壁２との間が防水シールされる。 Further, the operation of attaching the draining member 31 to the joist 22 with the fastening tool 79 is performed by bringing the waterproof member receiving portion 70D of the draining member 31 into contact with the outer wall 2 of the house, and the joisting member 31 with the fastening tool 79 is used. After the mounting operation to the waterproof member receiving portion 70D, a wet waterproof member 80 is filled on the waterproof member receiving portion 70D, and the waterproof member 80 received by the waterproof member receiving portion 70D is dried and solidified. A waterproof seal is provided between the outer wall 2 of the house.

図５には、前記根太２２を受けている前記根太受け部材２０も示されている。根太受け部材２０における根太２２の下側に配置された先端部は起立部２０Ａとなっており、この起立部２０Ａにより、根太受け部材２０の先部には溝２０Ｂが形成されている。この溝２０Ｂは、前述した溝カバー３０が配置されているデッキ部材２６，２７の溝と同じく、住宅の外壁２に沿って延びている根太受け部材２０の長さ方向の端部まで連続し、溝２０Ｂは、根太受け部材２０のこの端部の位置で開口している。 FIG. 5 also shows the joist receiving member 20 receiving the joist 22. A tip portion disposed below the joist 22 in the joist receiving member 20 is an upstanding portion 20A, and a groove 20B is formed at the tip of the joist receiving member 20 by the upstanding portion 20A. This groove 20B continues to the end in the longitudinal direction of the joist receiving member 20 extending along the outer wall 2 of the house, like the grooves of the deck members 26 and 27 in which the groove cover 30 is disposed. The groove 20 B opens at the position of this end portion of the joist receiving member 20.

水切り部材３１を含むバルコニ１の床に雨が降ると、この床を形成しているデッキ部材２６〜２８は、上述したように、バルコニ１の張り出し方向へ下り傾斜した水勾配をもって並設されているため、雨水はデッキ部材２６〜２８の上面部に沿ってバルコニ１の外側方向へ流下し、水勾配方向の最も下側に配置されたデッキ部材２８の下流側の部分に集まる。 When it rains on the floor of the balcony 1 including the draining member 31, the deck members 26 to 28 forming the floor are arranged side by side with a water gradient inclined downward in the protruding direction of the balcony 1, as described above. Therefore, the rainwater flows down along the upper surfaces of the deck members 26 to 28 toward the outside of the balcony 1 and collects at the downstream portion of the deck member 28 arranged at the lowest side in the water gradient direction.

図４は、このデッキ部材２８及びその周辺を示す図１の一部拡大図である。デッキ部材２８の水勾配方向上流側の端部２８Ａは、前記止着具２９で根太２２に止着されている。デッキ部材２７の水勾配方向下流側の端部２７Ａは、デッキ部材２８の上面部２８Ｄの上に防水部材３３Ａを介して載せられ、デッキ部材２８に、端部２８Ａよりも水勾配方向下流側に形成されている起立部２８Ｈは、デッキ部材２７に形成されている下段部２７Ｂの下面に防水部材３３Ｂを介して当接している。そして、デッキ部材２８の起立部２８Ｈよりも水勾配方向下流側は溝３２となっており、この溝３２は、上記溝カバー３０が配置されているデッキ部材２６，２７の溝と同じく、デッキ部材２８の長さ方向の端部まで連続し、この端部の位置で開口している。また、デッキ部材２８の脚部２８Ｃの上端に形成されている上記上面部２８Ｄは、歩行可能な面となっている。 4 is a partially enlarged view of FIG. 1 showing the deck member 28 and its periphery. An end 28 A on the upstream side in the water gradient direction of the deck member 28 is fixed to the joist 22 with the fixing tool 29. An end portion 27A on the downstream side in the water gradient direction of the deck member 27 is placed on the upper surface portion 28D of the deck member 28 via a waterproof member 33A, and on the deck member 28 on the downstream side in the water gradient direction from the end portion 28A. The formed standing portion 28H is in contact with the lower surface of the lower step portion 27B formed on the deck member 27 via the waterproof member 33B. A groove 32 is formed on the downstream side of the standing portion 28H of the deck member 28 in the water gradient direction. The groove 32 is the same as the grooves of the deck members 26 and 27 in which the groove cover 30 is disposed. It continues to the end in the length direction of 28, and opens at the position of this end. Further, the upper surface portion 28D formed at the upper end of the leg portion 28C of the deck member 28 is a walkable surface.

なお、デッキ部材２７とデッキ部材２８とのこの連続構造において、防水部材３３Ａ、３３Ｂを省略してもよい。 In the continuous structure of the deck member 27 and the deck member 28, the waterproof members 33A and 33B may be omitted.

デッキ部材２８には、上面部２８Ｄよりも水勾配方向下流側において、樋部４０が形成され、この樋部４０は上向きに開口した凹部となっている。このため、樋部４０は、水勾配方向下流側と上流側の立上り壁４０Ａと４０Ｂと、これらの立上り壁４０Ａと４０Ｂの間の底面部４０Ｃとからなる。このような凹部による樋部４０は、バルコニ１の左右方向に延びているデッキ部材２８の全長に亘って形成されている。デッキ部材２８には、水勾配方向下流側の立上り壁４０Ａと連続していてバルコニ１の内側へ下り傾斜した傾斜面部２８Ｅが設けられ、この傾斜面部２８Ｅの上端と連続している起立部２８Ｆの端部は、デッキ部材２８のバルコニ外側方向の先端部２８Ｇとなっている。この先端部２８Ｇは、バルコニ１の内側に向かって開口した断面コ字形状となっている。 The deck member 28 is formed with a flange portion 40 on the downstream side in the water gradient direction from the upper surface portion 28D, and the flange portion 40 is a concave portion opened upward. For this reason, the collar part 40 consists of the rising walls 40A and 40B on the downstream side and the upstream side in the water gradient direction, and the bottom surface part 40C between these rising walls 40A and 40B. The collar portion 40 formed by such a recess is formed over the entire length of the deck member 28 extending in the left-right direction of the balcony 1. The deck member 28 is provided with an inclined surface portion 28E that is continuous with the rising wall 40A on the downstream side in the water gradient direction and is inclined downward toward the inside of the balcony 1, and an upright portion 28F that is continuous with the upper end of the inclined surface portion 28E. The end portion is a front end portion 28G of the deck member 28 in the direction of the balcony outer side. This tip portion 28G has a U-shaped cross section that opens toward the inside of the balcony 1.

デッキ部材２８とバルコニ内外方向に隣接している前述したバルコニ桁梁部材１０には、この桁梁部材１０の上面から一体にバルコニ１の内側に延びる水切り部１０Ａが設けられ、デッキ部材２８の先端部２８Ｇはこの水切り部１０Ａの下側に配置されているとともに、先端部２８Ｇは水切り部１０Ａの下面に結合具４１で結合されており、先端部２８Ｇと水切り部１０Ａとの結合は、先端部２８Ｂと桁梁部材１０のバルコニ内側の面１０Ｂとの間に防水部材４２が介設されてなされている。なお、先端部２８Ｇと水切り部１０Ａとの間に防水部材を配置してもよい。 The above-described balcony girder beam member 10 adjacent to the deck member 28 in the balconi inside / outside direction is provided with a draining portion 10A that integrally extends from the upper surface of the girder beam member 10 to the inside of the balcony 1. The portion 28G is disposed below the draining portion 10A, and the distal end portion 28G is coupled to the lower surface of the draining portion 10A with a coupler 41, and the coupling between the distal end portion 28G and the draining portion 10A is performed at the distal end portion. A waterproof member 42 is interposed between 28B and the inner surface 10B of the beam member 10. A waterproof member may be disposed between the tip portion 28G and the draining portion 10A.

デッキ部材２８の凹部による樋部４０には、デッキ部材２８の全長又は略全長に亘る長さを有する樋カバー４５が取り外し可能に配置されている。この樋カバー４５は、例えば、アルミ合金による金属製であって、デッキ部材２８と同じ材料で形成されている。また、樋カバー４５は、上面部４５Ａと、水勾配方向に離れている一対の脚部４５Ｂと、上面部４５Ａの水勾配方向両側の端部に設けられた垂下部４５Ｃとからなる。また、上面部４５Ａと脚部４５Ｂには水通過部である孔４６が形成され、脚部４５Ｂにおける樋部４０の底面部４０Ｃと接触している下端には、水通過部である切り欠き４７が形成されている。 A collar cover 45 having a length extending over the entire length or substantially the entire length of the deck member 28 is detachably disposed on the collar portion 40 formed by the concave portion of the deck member 28. The eaves cover 45 is made of, for example, a metal made of an aluminum alloy, and is formed of the same material as the deck member 28. Moreover, the eaves cover 45 includes an upper surface portion 45A, a pair of leg portions 45B separated in the water gradient direction, and a hanging portion 45C provided at both ends of the upper surface portion 45A in the water gradient direction. A hole 46 that is a water passage portion is formed in the upper surface portion 45A and the leg portion 45B, and a notch 47 that is a water passage portion is formed at the lower end of the leg portion 45B that is in contact with the bottom surface portion 40C of the flange portion 40. Is formed.

樋カバー４５の上面部４５Ａは踏み付け可能な強度を有し、脚部４５Ｂもこの踏み付け力に対する充分な強度を有し、このため、人が樋カバー４５の上に立つことや歩行することが可能である。また、樋カバー４５を樋部４０に配置したときにおける上面部４５Ａの高さ位置は、図４で示されているように、デッキ部材２８自身が有している水勾配を考慮しても、また考慮しなくても、デッキ部材２８の上記上面部２８Ｄの高さ位置と略一致している。したがって、人がバルコニ１の床を歩行したとき、これらの上面部４５Ａと２８Ｄの間で殆ど高さのギャップを感じることがない。 The upper surface portion 45A of the heel cover 45 has a strength capable of being stepped on, and the leg portion 45B also has a sufficient strength against the stepping force, so that a person can stand on the heel cover 45 or walk. It is. In addition, the height position of the upper surface portion 45A when the heel cover 45 is disposed on the heel portion 40 is, as shown in FIG. 4, considering the water gradient of the deck member 28 itself, Further, even if not taken into consideration, the height position of the upper surface portion 28D of the deck member 28 is substantially coincident. Therefore, when a person walks on the floor of the balcony 1, there is almost no height gap between the upper surface portions 45A and 28D.

なお、樋カバー４５を樋部４０に配置したときにおける上面部４５Ａの高さ位置を、デッキ部材２８の上面部２８Ｄの高さ位置と一致させてもよい。 The height position of the upper surface portion 45 A when the heel cover 45 is disposed on the heel portion 40 may coincide with the height position of the upper surface portion 28 D of the deck member 28.

図２で示されているとおり、前述した妻梁部材１１には、バルコニ１の内側において、上樋部材５０が取り付けられている。この上樋部材５０は、図１で示されているように、デッキ部材２６〜２８に跨るバルコニ１の張り出し方向への長さを有し、その前後の端部５０Ａ，５０Ｂは塞がれている。また、上樋部材５０は、図２で示されているように、妻梁部材１１のバルコニ内側の面１１Ａに結合された外側壁部５０Ｃと、上端部がデッキ部材２６〜２８に、下端部が桁梁部材１０の前記根太受け部２１及び図１で示されている前記根太受け部材２０にそれぞれ結合された内側壁部５０Ｄと、外側壁部５０Ｃの下端部と内側壁部５０Ｄの高さ中間部との間に架設されている底面部５０Ｅとからなる。 As shown in FIG. 2, an upper eaves member 50 is attached to the end beam member 11 described above inside the balcony 1. As shown in FIG. 1, the upper collar member 50 has a length in the protruding direction of the balcony 1 straddling the deck members 26 to 28, and the front and rear end portions 50A and 50B are closed. Yes. Further, as shown in FIG. 2, the upper collar member 50 includes an outer wall portion 50 C coupled to the inner surface 11 A of the end beam member 11, an upper end portion on the deck members 26 to 28, and a lower end portion. Are the inner wall portion 50D respectively coupled to the joist receiving portion 21 of the beam member 10 and the joist receiving member 20 shown in FIG. 1, and the lower end portion of the outer wall portion 50C and the height of the inner wall portion 50D. It consists of the bottom face part 50E constructed between the intermediate part.

このような形状となっている上樋部材５０は、図１で示されているとおり、バルコニ１の外側方向へ下り傾斜した水勾配を有している。そして、上樋部材５０の底面部５０Ｅの水勾配方向下流端部又はその近傍には、下側へ延びる短寸の縦樋部材５１が取り付けられている。 As shown in FIG. 1, the upper collar member 50 having such a shape has a water gradient inclined downward toward the outer side of the balcony 1. A short vertical rod member 51 extending downward is attached to the downstream end portion in the water gradient direction of the bottom surface portion 50E of the upper rod member 50 or in the vicinity thereof.

また、図２で示されているように、上樋部材５０の外側壁部５０Ｃの上端部にはカバー部材５２が取り付けられ、デッキ部材２６〜２８の上方においてバルコニ１の内側へ延出しているこのカバー部材５２によって上樋部材５０の上方が塞がれている。 As shown in FIG. 2, a cover member 52 is attached to the upper end portion of the outer wall portion 50 C of the upper collar member 50 and extends to the inside of the balcony 1 above the deck members 26 to 28. The upper part of the upper collar member 50 is blocked by the cover member 52.

図２で示すように、上樋部材５０の下側には下樋部材６０が配置され、バルコニ１の張り出し方向へ下り勾配となって配置されているこの下樋部材６０は妻梁部材１１の下面を下側から覆うとともに、上樋部材５０を越えてバルコニ１の内側方向に達する幅寸法を有し、下樋部材６０の幅方向両側の立上り端部６０Ａ，６０Ｂのうち、バルコニ１の外側方向の立上り端部６０Ａは妻梁部材１１の下面に結合され、バルコニ１の内側方向の立上り端部６０Ｂは、桁梁部材１０の前記根太受け部２１と、図１で示されている前記根太受け部材２０とに結合されている。また、下樋部材６０は、図１で示されているように、桁梁部材１０の前面１０Ｃ（この前面１０Ｃは妻梁部材１１の先端面と一致している）から住宅の前記外壁２の近くまで達する長さを有し、この長さは上樋部材５０の長さよりも長い。そして、下樋部材６０の前端部６０Ｃは塞がれており、後端部もキャップ部材６１で塞がれている。 As shown in FIG. 2, a lower heel member 60 is disposed below the upper heel member 50, and the lower heel member 60 disposed in a downward slope in the overhanging direction of the balcony 1 The lower surface is covered from the lower side and has a width dimension that reaches the inner side of the balcony 1 beyond the upper heel member 50. Of the rising end portions 60A, 60B on both sides in the width direction of the lower heel member 60, The rising end portion 60A in the direction is coupled to the lower surface of the end beam member 11, and the rising end portion 60B in the inner direction of the balcony 1 is the joist receiving portion 21 of the beam member 10 and the joists shown in FIG. Coupled to the receiving member 20. Further, as shown in FIG. 1, the lower eaves member 60 extends from the front surface 10C of the beam member 10 (this front surface 10C coincides with the front end surface of the beam member 11) to the outer wall 2 of the house. It has a length that reaches near, and this length is longer than the length of the upper collar member 50. The front end portion 60 C of the lower collar member 60 is closed, and the rear end portion is also closed with the cap member 61.

下樋部材６０の底面部６０Ｄには、桁梁部材１０の近くにおいて、樋部材６２が接続され、バルコニ１の下面から露出しているこの樋部材６２には、住宅の前記外壁２に沿って下側へ延びる縦樋部材６４が中間樋部材６３を介して接続されている。なお、下樋部材６０の水勾配を住宅の外壁２側へ下り勾配とすることにより、この外壁２の近くにおいて樋部材６２を下樋部材６２に接続してもよい。 A bottom member 60D is connected to the bottom surface portion 60D of the lower member 60 in the vicinity of the beam member 10 and is exposed along the outer wall 2 of the house. A vertical rod member 64 extending downward is connected via an intermediate rod member 63. In addition, you may connect the eaves member 62 to the lower eaves member 62 in the vicinity of this outer wall 2 by making the water gradient of the lower eaves member 60 into the downward slope toward the outer wall 2 side of a house.

以上の上樋部材５０及び下樋部材６０は、バルコニ１の左右両側に２本ある妻梁部材１１ごとに設けられ、また、樋部材６２〜６４も妻梁部材１１ごとに設けられている。 The upper collar member 50 and the lower collar member 60 described above are provided for each of the two beam members 11 on both the left and right sides of the balcony 1, and the collar members 62 to 64 are also provided for each of the beam members 11.

前述したように、バルコニ１の床に雨が降ると、雨水はデッキ部材２６〜２８の上面部に沿ってバルコニ１の外側方向へ流下することになり、水勾配方向の最も下側に配置されたデッキ部材２８に達した雨水は、このデッキ部材２８に上向きに開口した凹部として形成されている前記樋部４０に流れ落ちる。この樋部４０には樋カバー４５が配置されているが、この樋カバー４５は、樋部４０よりもバルコニ１の内外方向（前記水勾配方向及びバルコニ１の張り出し方向）の幅寸法が小さく、かつ、上面部４５Ａや脚部４５Ｂには、水通過部となっている孔４６、切り欠き４７が形成されているため、樋カバー４５は雨水が樋部４０に流入する際の障害にはならない。 As described above, when rain falls on the floor of the balcony 1, the rainwater flows down along the upper surfaces of the deck members 26 to 28 toward the outside of the balconi 1, and is disposed at the lowest side in the water gradient direction. The rainwater that has reached the deck member 28 flows down to the flange portion 40 formed as a recess opening upward in the deck member 28. The collar cover 45 is provided with a collar cover 45, and the collar cover 45 has a smaller width dimension in the inside / outside direction of the balcony 1 (the water gradient direction and the bulging direction of the balcony 1) than the collar part 40, And since the hole 46 and the notch 47 which are water passage parts are formed in the upper surface part 45A and the leg part 45B, the hail cover 45 does not become an obstacle when rainwater flows into the hail part 40. .

樋部４０に流れ落ちた雨水は、樋部４０がデッキ部材２８の長さ方向両端部で開口しているためこれらの開口端部から落下し、その下に配置されている図２の上樋部材５０に達する。そして、雨水は、前記短寸の縦樋部材５１から下樋部材６０に流下し、この下樋部材６０から樋部材６２〜６４を経てバルコニ１の外部に排出される。 The rainwater that has flowed down to the ridge portion 40 falls from these opening end portions because the ridge portion 40 is open at both ends in the length direction of the deck member 28, and the upper ridge member shown in FIG. Reach 50. Then, rainwater flows down from the short vertical gutter member 51 to the lower gutter member 60 and is discharged from the lower gutter member 60 to the outside of the balcony 1 through gutter members 62 to 64.

また、たとえ、前記溝カバー３０が配置されているデッキ部材２６，２７の前記溝や、デッキ部材２８に形成されている前記溝３２、デッキ部材２６とデッキ部材２７との間の隙間に雨水が侵入しても、これらの溝や隙間は、樋部４０と同様に、それぞれのデッキ部材２６〜２８の長さ方向両端部まで延びているため、これらの溝や隙間に侵入した雨水は、溝や隙間の長さ方向端部からデッキ部材２６〜２８の下側に配置されている上樋部材５０へ落下し、これ以後、上述の雨水と同様にして下樋部材６０等を経てバルコニ１の外部に排出される。 For example, rainwater may enter the grooves of the deck members 26 and 27 where the groove cover 30 is disposed, the grooves 32 formed in the deck member 28, and the gap between the deck member 26 and the deck member 27. Even if it invades, since these grooves and gaps extend to both ends in the longitudinal direction of the respective deck members 26 to 28, as with the flange 40, rainwater that has entered these grooves and gaps is Or from the lengthwise end of the gap to the upper eaves member 50 disposed below the deck members 26 to 28, and thereafter, through the lower eaves member 60 and the like in the same manner as the above-mentioned rainwater, It is discharged outside.

また、たとえ、図５で示した水切り部材３１の防水部材受け部７０Ｄで受けられている防水部材８０と住宅の外壁２との間に雨水等の水が侵入し、この水が防水部材受け部７０Ｄと住宅の外壁２との間から下に落下することがあっても、この水は、根太受け部材２０の前記溝２０Ｂに達するため、この溝２０Ｂから上述の雨水と同様にして上樋部材５０や下樋部材６０等を経てバルコニ１の外部に排出される。 Further, for example, water such as rainwater enters between the waterproof member 80 received by the waterproof member receiving portion 70D of the draining member 31 shown in FIG. 5 and the outer wall 2 of the house, and this water becomes the waterproof member receiving portion. Even if the water drops from between 70D and the outer wall 2 of the house, this water reaches the groove 20B of the joist receiving member 20, so that the upper eaves member is formed from the groove 20B in the same manner as the rainwater described above. It is discharged to the outside of the balcony 1 through 50, the lower collar member 60 and the like.

さらに、住宅の外壁２とデッキ部材２６との間は、デッキ部材２６〜２８と同じ又は略同じ長さ寸法を有していて外壁２に沿って延びている図５の水切り部材３１で防水されており、この水切り部材３１の防水シール片７１は、デッキ部材２６の上面部２６Ａの一部を形成している前記突出片４６に接触し、これにより、デッキ部材２６のこの箇所が防水シールされているため、雨水が防水シール片７１よりも住宅の外壁２側に達することが防止されている。 Further, the space between the outer wall 2 of the house and the deck member 26 is waterproofed by the draining member 31 of FIG. 5 having the same or substantially the same length as the deck members 26 to 28 and extending along the outer wall 2. The waterproof seal piece 71 of the draining member 31 is in contact with the projecting piece 46 forming a part of the upper surface portion 26A of the deck member 26, whereby this portion of the deck member 26 is waterproof-sealed. Therefore, rainwater is prevented from reaching the outer wall 2 side of the house from the waterproof seal piece 71.

そして、雨水が、たとえ、この防水シール片７１よりも住宅の外壁２側に達することがあっても、デッキ部材２６のこの部分は、上向きに開口した図５の前記溝７８となっているため、雨水はこの溝７８に落下することになる。また、溝７８は、デッキ部材２６の長さ方向の両端部まで達する長さを有し、溝７８の両端部はデッキ部材２６の長さ方向の両端部で開口しているため、溝７８に落下した雨水は、溝７８の開口端部から前記上樋部材５０へ落下し、これ以後、前述した下樋部材６０等からなる流出経路を経てバルコニ１の外部に排出される。 And even if rainwater reaches the outer wall 2 side of the house from the waterproof seal piece 71, this portion of the deck member 26 is the groove 78 of FIG. 5 that opens upward. Rainwater will fall into this groove 78. Further, the groove 78 has a length that reaches both ends of the deck member 26 in the length direction, and both ends of the groove 78 are open at both ends in the length direction of the deck member 26. The rainwater that has fallen falls from the opening end of the groove 78 to the upper heel member 50 and is then discharged to the outside of the balcony 1 through the outflow path comprising the lower heel member 60 and the like.

また、図２で説明したように、上樋部材５０の外側壁部５０Ｃは妻梁部材１１のバルコニ内側の面１１Ａに結合されているが、雨水がこれらの外側壁部５０Ｃと面１１Ａとの間に侵入しても、この下には、上樋部材５０の長さの全体をカバーして配置されている下樋部材６０が設けられているため、このような雨水も下樋部材６０等を経てバルコニ１の外部に排出される。 Further, as described with reference to FIG. 2, the outer wall portion 50C of the upper eaves member 50 is coupled to the inner surface 11A of the balcony of the end beam member 11, but rainwater is formed between the outer wall portion 50C and the surface 11A. Even if it intrudes in the middle, the lower eaves member 60 is provided below the upper eaves member 50 so as to cover the entire length of the upper eaves member 50. After that, it is discharged to the outside of Balconi 1.

さらに、桁梁部材１０と妻梁部材１１との接合部の隙間に雨水が侵入しても、この隙間の下端から落下した雨水は下樋部材６０の上に落ちることになるため、このような雨水も下樋部材６０等を経てバルコニ１の外部へ排出される。 Furthermore, even if rainwater enters the gap at the joint between the beam member 10 and the beam member 11, rainwater that has dropped from the lower end of the gap will fall on the lower eaves member 60. Rainwater is also discharged to the outside of the balcony 1 through the lower arm 60 and the like.

さらに、デッキ部材２８に上向きの凹部となって形成された樋部４０には、踏み付け可能となった上面部４５Ａを有する樋カバー４５が配置されているため、この樋部４０の部分でも、樋カバー４５の上で立つことや歩行することが可能となり、このため、バルコニ床を形成するデッキ部材２８に樋部４０を形成しても、バルコニの有効床面積を大きくすることができる。 Further, since the collar portion 40 formed as an upward concave portion on the deck member 28 is provided with a collar cover 45 having an upper surface portion 45A that can be stepped on, the collar portion 40 also has a collar portion 40. It is possible to stand on the cover 45 and to walk. Therefore, even if the collar portion 40 is formed on the deck member 28 forming the balconi floor, the effective floor area of the balconi can be increased.

なお、左右寸法が大きいバルコニについては、前述した左右２本の妻梁部材１１の間にこれらの妻梁部材１１と平行に中間梁部材が設けられ、妻梁部材１１と同じく基端部がアーム部材を介して住宅の梁部材３に結合されるこの中間梁部材と一方の妻梁部材１１との間及び中間梁部材と他方の妻梁部材１１との間に、それぞれ桁梁部材が架設される。そして、凹部による樋部４０が形成されているデッキ部材２８を含むデッキ部材２６〜２８と水切り部材３１も、中間梁部材と一方の妻梁部材１１との間及び中間梁部材と他方の妻梁部材１１との間に配置され、中間梁部材の左右両側に、図２で示した妻梁部材１１に対する構造と同様な構造によって上樋部材５０と下樋部材６０が配置され、これらの下樋部材６０に樋部材６２〜６４が接続されることにより、中間梁部材の左右両側に配置されたそれぞれのデッキ部材２８の樋部４０やデッキ部材２６の溝７８等に落下した雨水は、これらの樋部材５０，６０，６２〜６４を経てバルコニ１の外部に排出される。 For the balconi having a large left and right dimension, an intermediate beam member is provided between the two left and right end beam members 11 in parallel with the end beam members 11, and the base end portion is an arm like the end beam members 11. Girder members are erected between the intermediate beam member coupled to the beam member 3 of the house via the member and the one beam member 11, and between the intermediate beam member and the other beam member 11, respectively. The And the deck members 26-28 including the deck member 28 in which the collar part 40 by the recessed part is formed, and the draining member 31 are also between the intermediate beam member and the one end beam member 11 and between the intermediate beam member and the other end beam. The upper eaves member 50 and the lower eaves member 60 are arranged on the left and right sides of the intermediate beam member by the same structure as that of the end beam member 11 shown in FIG. When the eaves members 62 to 64 are connected to the member 60, the rainwater that has fallen into the eaves 40 of the respective deck members 28 and the grooves 78 of the deck members 26 disposed on the left and right sides of the intermediate beam member, It is discharged to the outside of the balcony 1 through the flange members 50, 60, 62 to 64.

以上説明した本実施形態によると、防水シール片７１を有する水切り部材３１により、住宅の外壁２とデッキ部材２６との間を防水できるとともに、水切り部材３１の先端よりも住宅の外壁２側のデッキ部材２６の部分には、具体的には、この水切り部材３１の防水シール片７１が接触している突出片７６よりも住宅の外壁２側のデッキ部材２６の部分には、上向きに開口した溝７８が形成されているため、防水シール片７１とデッキ部材２６との接触箇所を抜けて外壁２側に達する雨水等の水があっても、この水は溝７８に落下することになり、外壁２とデッキ部材２６との間に落下することが防止される。 According to the present embodiment described above, the draining member 31 having the waterproof seal piece 71 can waterproof between the outer wall 2 of the house and the deck member 26, and the deck on the outer wall 2 side of the house from the tip of the draining member 31. Specifically, in the part of the member 26, a groove opened upward in the part of the deck member 26 closer to the outer wall 2 of the house than the protruding piece 76 with which the waterproof seal piece 71 of the draining member 31 is in contact. 78 is formed, even if there is water such as rainwater that passes through the contact portion between the waterproof seal piece 71 and the deck member 26 and reaches the outer wall 2 side, this water will fall into the groove 78, and the outer wall 2 and the deck member 26 are prevented from falling.

また、溝７８はデッキ部材２６の長さ方向の両端部で開口しているため、溝７８に落下した水は、溝７８に案内されて流れた後、溝７８の開口端部から落下し、その下には上樋部材５０が配置されているため、この水を、この上樋部材５０等を経てバルコニ１の外部に排出することができる。 Further, since the groove 78 is open at both ends in the length direction of the deck member 26, the water that has dropped into the groove 78 flows while being guided by the groove 78 and then drops from the opening end of the groove 78. Since the upper gutter member 50 is disposed below the water, this water can be discharged to the outside of the balcony 1 through the upper gutter member 50 and the like.

また、溝７８の外壁２側の端部は、デッキ部材２６の外壁２側の後端部７４となっており、立上り壁となっているこの後端部７４と水切り部材３１の上下延出部７０Ａとの間には、防水部材７２が介設されているため、溝７８に落下した水が、たとえ、この後端部７４を越えることがあっても、この水が後端部７４と上下延出部７０Ａとの間に侵入して根太２２同士の間から落下することは、防水部材７２によって阻止される。 Further, the end portion of the groove 78 on the outer wall 2 side is a rear end portion 74 on the outer wall 2 side of the deck member 26, and the rear end portion 74 that is a rising wall and the vertically extending portion of the draining member 31. Since the waterproof member 72 is interposed between the rear end portion 74 and the water, the water drops between the rear end portion 74 and the upper and lower portions. It is blocked by the waterproof member 72 from entering between the extending portions 70 A and falling from between the joists 22.

さらに、この防水部材７２は、デッキ部材２６が水切り部材３１に対して配置される前に、予め水切り部材３１の上下延出部７０Ａに取り付けられているため、デッキ部材２６の突出片７６を水切り部材３１の防水シール片７１に接触させて水切り部材３１に対するデッキ部材２６の配置作業を行うと、自ずと防水部材７２をデッキ部材２６の後端部７４と水切り部材３１の上下延出部７０Ａとの間に介設することができ、この介設作業を容易に行える。 Further, since the waterproof member 72 is attached to the vertically extending portion 70A of the draining member 31 in advance before the deck member 26 is arranged with respect to the draining member 31, the protruding piece 76 of the deck member 26 is drained. When the deck member 26 is arranged with respect to the draining member 31 in contact with the waterproof seal piece 71 of the member 31, the waterproof member 72 is naturally connected to the rear end portion 74 of the deck member 26 and the vertically extending portion 70A of the draining member 31. It can be interposed, and this intervention work can be performed easily.

また、防水部材７２は、デッキ部材２６の後端部７４と水切り部材３１の上下延出部７０Ａとで圧縮変形されるため、防水部材７２によるデッキ部材２６の後端部７４と水切り部材３１の上下延出部７０Ａとの間の防水シール性を向上させることができる。 Further, since the waterproof member 72 is compressed and deformed by the rear end portion 74 of the deck member 26 and the vertically extending portion 70 A of the draining member 31, the rear end portion 74 of the deck member 26 and the draining member 31 by the waterproof member 72 are compressed. The waterproof sealability between the upper and lower extension portions 70A can be improved.

さらに、水切り部材部材３１と住宅の外壁２との間は前記防水部材８０で防水シールすることができるとともに、この防水部材８０は、水切り部材３１に形成された防水部材受け部７０Ｄで受けられているため、防水部材８０を脱落させることなく所定位置に配置することができる。 Further, the waterproof member 80 can be waterproof-sealed between the draining member 31 and the outer wall 2 of the house, and the waterproof member 80 is received by a waterproof member receiving portion 70 D formed on the draining member 31. Therefore, the waterproof member 80 can be arranged at a predetermined position without dropping off.
