図１に示す本実施形態の外壁構造は、壁下地６と、壁下地６に固定されたジョイナー１と、ジョイナー１を介して隣り合う外壁材７０，７１とを具備している。 (Outer wall structure)
The outer wall structure of the present embodiment shown in FIG. 1 includes a wall base 6, a joiner 1 fixed to the wall base 6, and outer wall materials 70 and 71 adjacent to each other via the joiner 1.

本実施形態の壁下地６は、柱等の建物躯体９０の屋外側面に防水シート９１を介して固定された複数の縦胴縁６０で構成されている。以下、壁下地６を構成する複数の縦胴縁６０のうち、隣り合う外壁材７０，７１間の屋内側に位置する縦胴縁６０を縦胴縁６０ａという。 The wall base 6 of the present embodiment is composed of a plurality of vertical furring strips 60 fixed to the outdoor side surface of the building frame 90 such as pillars via a waterproof sheet 91. Hereinafter, among the plurality of vertical furring strips 60 constituting the wall base 6, the vertical furring strip 60 located on the indoor side between the adjacent outer wall materials 70 and 71 is referred to as the vertical furring strip 60a.

ジョイナー１は、隣り合う外壁材７０，７１の間の目地６１に設けられる。ジョイナー１は、縦胴縁６０ａの屋外側面に屋外側から取り付けられたベース材２と、ベース材２に屋外側から取り付けられて、隣り合う外壁材７０，７１の目地６１側の端をカバーするカバー材５とを備えている。 The joiner 1 is provided at the joint 61 between the adjacent outer wall materials 70 and 71. The joiner 1 covers the base material 2 attached to the outdoor side surface of the vertical furring strip 60a from the outdoor side, and the edges of the adjacent outer wall materials 70 and 71 on the joint 61 side attached to the base material 2 from the outdoor side. It is provided with a cover material 5.

ベース材２は、上下方向に延びた長尺な部材である。本実施形態のベース材２は、金属製であって、一枚の金属板を折り曲げて形成されている。 The base material 2 is a long member extending in the vertical direction. The base material 2 of the present embodiment is made of metal and is formed by bending a single metal plate.

図２に示すように、ベース材２は、縦胴縁６０ａの屋外側面に固定された固定部２０と、固定部２０から屋外側に突出した一対の被差込板部２１，２２とを有している。 As shown in FIG. 2, the base material 2 has a fixing portion 20 fixed to the outdoor side surface of the vertical furring strip 60a, and a pair of insertion plate portions 21 and 22 protruding from the fixing portion 20 to the outdoor side. is doing.

固定部２０は、縦胴縁６０ａの屋外側面に沿って上下方向に延びた帯状に形成されている。固定部２０の幅方向は、上下方向及び屋内外方向の両者に対して直交している。すなわち、屋内外方向を前後方向としたとき、固定部２０の幅方向は、左右方向と平行である。 The fixing portion 20 is formed in a strip shape extending in the vertical direction along the outdoor side surface of the vertical furring strip 60a. The width direction of the fixed portion 20 is orthogonal to both the vertical direction and the indoor / outdoor direction. That is, when the indoor / outdoor direction is the front-rear direction, the width direction of the fixed portion 20 is parallel to the left-right direction.

固定部２０の幅方向の中間部には、屋外側に向かって突出した一対の被差込板部２１，２２が形成されている。一対の被差込板部２１，２２は、固定部２０と一体に形成されている。 A pair of insertion plate portions 21 and 22 protruding toward the outdoor side are formed in the middle portion in the width direction of the fixed portion 20. The pair of insertion plate portions 21 and 22 are integrally formed with the fixing portion 20.

一対の被差込板部２１，２２は、固定部２０の幅方向（目地６１の幅方向）に隙間２３を介して離間しており、互いに対向している。一対の被差込板部２１，２２の各々は、対応する外壁材７０，７１の目地６１側の端面７２，７３と対向する。 The pair of insertion plate portions 21 and 22 are separated from each other through the gap 23 in the width direction of the fixing portion 20 (the width direction of the joint 61) and face each other. Each of the pair of insertion plate portions 21 and 22 faces the end faces 72 and 73 on the joint 61 side of the corresponding outer wall materials 70 and 71.

固定部２０において一対の被差込板部２１，２２の間に対応する部分は、釘からなる固着具９２が挿通される挿通部２４である。挿通部２４において上下方向の複数箇所の各々には、固着具９２が固定部２０の厚み方向に挿通されている。各固着具９２は、縦胴縁６０ａにねじ込まれており、これにより固定部２０は縦胴縁６０ａの屋外側面に固定されている。 The portion of the fixing portion 20 corresponding between the pair of insertion plate portions 21 and 22 is the insertion portion 24 into which the fastener 92 made of a nail is inserted. Fastening tools 92 are inserted in the thickness direction of the fixing portion 20 at each of the plurality of vertical positions in the insertion portion 24. Each fastener 92 is screwed into the vertical furring strip 60a, whereby the fixing portion 20 is fixed to the outdoor side surface of the vertical furring strip 60a.

固定部２０の幅方向の両側部分２５，２６は、一対の被差込板部２１，２２よりも固定部２０の幅方向外側に向かって突出している。固定部２０の幅方向の両端には、固定部２０の表面（屋外側面）に沿って折り返された折返部２７，２８が形成されている。 Both side portions 25 and 26 of the fixed portion 20 in the width direction protrude toward the outside of the fixed portion 20 in the width direction from the pair of insertion plate portions 21 and 22. Folded portions 27, 28 folded along the surface (outdoor side surface) of the fixed portion 20 are formed at both ends of the fixed portion 20 in the width direction.

一対の被差込板部２１，２２の各々は、金属板の一部を折り重ねて形成された二重の板状部分によって構成されている。 Each of the pair of insertion plate portions 21 and 22 is composed of a double plate-shaped portion formed by folding a part of a metal plate.

各被差込板部２１，２２の幅方向内側の端面は、他方の被差込板部に対向する対向面２９，３０となっている。各被差込板部２１，２２の対向面２９，３０は、固定部２０の幅方向（左右方向）に対して傾斜しており、一対の被差込板部２１，２２の対向面２９，３０同士の間隔Ｌは屋外側に近づく程徐々に狭くなっている。このように傾斜させる手段としては、金属板を折り重ねて形成する際に、折り目部分を潰してしまわず、折り曲げ部分の金属板間に隙間が形成されるようにする。こうすることで、被差込板部２１，２２の外側面同士が平行となるように被差込板部２１，２２の固定部２０側の二重の金属板同士を接触させると、前記隙間分だけ、被差込板部２１，２２の内側面（対向面２９，３０）の屋外側付近が内側に位置するようになる。したがって、平行な外側面３１，３２により、止水部材４０，４１が対向する外壁材７０，７１の端面７２，７３に略均等に押し当てられるとともに、屋外側に向かって間隔が狭くなる内側面（対向面２９，３０）同士によりカバー材５が抜け難くなるものである。 The inner end faces of the insertion plate portions 21 and 22 in the width direction are facing surfaces 29 and 30 facing the other insertion plate portions. The facing surfaces 29 and 30 of the insertion plate portions 21 and 22 are inclined with respect to the width direction (left-right direction) of the fixing portion 20, and the facing surfaces 29 and 30 of the pair of insertion plate portions 21 and 22 are inclined. The distance L between the 30s gradually narrows as it approaches the outdoor side. As a means of inclining in this way, when the metal plates are folded and formed, the crease portion is not crushed and a gap is formed between the metal plates of the bent portion. By doing so, when the double metal plates on the fixed portion 20 side of the insertion plate portions 21 and 22 are brought into contact with each other so that the outer surfaces of the insertion plate portions 21 and 22 are parallel to each other, the gap is described. By the amount, the vicinity of the outdoor side of the inner side surfaces (opposing surfaces 29, 30) of the insertion plate portions 21 and 22 is located inside. Therefore, the parallel outer surfaces 31 and 32 press the water blocking members 40 and 41 against the end surfaces 72 and 73 of the facing outer wall materials 70 and 71 substantially evenly, and the inner surface becomes narrower toward the outdoor side. It is difficult for the cover material 5 to come off due to the facing surfaces 29 and 30.

各被差込板部２１，２２において対向面２９，３０と反対側の外側面３１，３２は、固定部２０の幅方向と直交している。各被差込板部２１，２２の外側面３１，３２には、止水部材４０，４１が取り付けられている。 In each of the insertion plate portions 21 and 22, the outer surfaces 31 and 32 opposite to the facing surfaces 29 and 30 are orthogonal to the width direction of the fixing portion 20.

The end faces 72, 73 of the outer wall materials 70, 71 are pressed against the surfaces of the corresponding water blocking members 40, 41 opposite to the insertion plate portions 21 and 22.

各止水部材４０，４１は、対応する外壁材７０，７１の端面７２，７３と対応する被差込板部２１，２２との間で、厚み方向に圧縮されている。これにより、各外壁材７０，７１と対応する被差込板部２１，２２との間が、止水部材４０，４１によってシール（水密）されている。 Each of the water blocking members 40 and 41 is compressed in the thickness direction between the end faces 72 and 73 of the corresponding outer wall materials 70 and 71 and the corresponding insertion plate portions 21 and 22. As a result, the space between the outer wall materials 70 and 71 and the corresponding insertion plate portions 21 and 22 is sealed (watertight) by the water blocking members 40 and 41.

ベース材２の一対の被差込板部２１，２２の間には、カバー材５が差し込まれて固定されている。カバー材５は上下方向に延びた長尺な部材である。本実施形態のカバー材５は、ゴム製である。 The cover material 5 is inserted and fixed between the pair of insertion plate portions 21 and 22 of the base material 2. The cover material 5 is a long member extending in the vertical direction. The cover material 5 of the present embodiment is made of rubber.

カバー材５は、ベース材２に差し込まれる差込片５１と、差込片５１の屋外側端部から幅方向に延びるカバー片５０とを有している。 The cover material 5 has an insertion piece 51 to be inserted into the base material 2 and a cover piece 50 extending in the width direction from the outdoor side end of the insertion piece 51.

カバー片５０は、上下方向に延びた帯状に形成されている。カバー片５０の幅方向は、上下方向及び屋内外方向の両者に対して直交している。 The cover piece 50 is formed in a strip shape extending in the vertical direction. The width direction of the cover piece 50 is orthogonal to both the vertical direction and the indoor / outdoor direction.

カバー片５０の幅方向の中間部には、一対の被差込片部２１，２２間に突出した差込片５１が形成されている。差込片５１は、カバー片５０から屋内側に向かって突出した芯部５２と、芯部５２から突出した複数の止水片５３とを有している。 An insertion piece 51 projecting between the pair of insertion pieces 21 and 22 is formed in the middle portion of the cover piece 50 in the width direction. The insertion piece 51 has a core portion 52 protruding from the cover piece 50 toward the indoor side, and a plurality of water blocking pieces 53 protruding from the core portion 52.

芯部５２は厚み方向がカバー片５０の幅方向と平行で上下方向に延びた帯状に形成されている。芯部５２の厚み方向の両側の面における屋内外方向の複数箇所の各々には、上下方向に延びた帯状の止水片５３が突設されている。本実施形態の差込片５１には、左右対称形状の対をなす止水片５３が、屋内外方向に間隔を介して複数対形成されている。 The core portion 52 is formed in a strip shape whose thickness direction is parallel to the width direction of the cover piece 50 and extends in the vertical direction. A strip-shaped water stop piece 53 extending in the vertical direction is provided so as to project from each of a plurality of indoor / outdoor directions on both side surfaces of the core portion 52 in the thickness direction.

It is pressed against the facing surfaces 29 and 30 of the portions 21 and 22. As a result, the insertion piece 51 is sandwiched and held between the pair of insertion plate portions 21 and 22, and the cover material 5 is fixed to the base material 2.

被差込板部２１，２２に圧接された各止水片５３は、芯部５２から屋外側に向かって突出している。このため、カバー材５に対して屋外側に向かう力が加わったとき、各止水片５３には屋内外方向に収縮する方向の力が加わる。したがって、差込片５１は一対の被差込板部２１，２２の間から屋外側に抜け難い。 Each water stop piece 53 pressed against the insertion plate portions 21 and 22 protrudes from the core portion 52 toward the outdoor side. Therefore, when a force toward the outdoor side is applied to the cover material 5, a force in the direction of contracting in the indoor / outdoor direction is applied to each water stop piece 53. Therefore, the insertion piece 51 is difficult to be pulled out from between the pair of insertion plate portions 21 and 22 to the outdoor side.

また、ベース材２の一対の被差込板部２１，２２の対向面２９，３０同士の間隔Ｌは、屋外側に近い程狭くなっている。このため、カバー材５に対して屋外側に向かう力が加わったとき、この力は対向面２９，３０で受けられる。したがって、差込片５１は一対の被差込板部２１，２２の間から一層抜け難くなっている。 Further, the distance L between the facing surfaces 29, 30 of the pair of insertion plate portions 21 and 22 of the base material 2 becomes narrower as it is closer to the outdoor side. Therefore, when a force toward the outdoor side is applied to the cover material 5, this force is received by the facing surfaces 29 and 30. Therefore, the insertion piece 51 is more difficult to be removed from between the pair of insertion plate portions 21 and 22.

差込片５１の屋外側端部に形成されたカバー片５０は、両外壁材７０，７１の表面（屋外側面）よりも屋外側に位置している。カバー片５０の幅方向の両側端部は、屋内側に向かって屈曲し、隣り合う両外壁材７０，７１の表面における目地６１側の端部に圧接されている。これにより、カバー片５０の幅方向両端部は、外壁材７０，７１の屋外側面に対して略線接触（上下方向に延びた線状に接触）している。 The cover piece 50 formed at the outdoor side end of the insertion piece 51 is located on the outdoor side of the surfaces (outdoor side surfaces) of both outer wall materials 70 and 71. Both side ends of the cover piece 50 in the width direction are bent toward the indoor side and are pressed against the ends on the joint 61 side on the surfaces of the adjacent outer wall materials 70 and 71. As a result, both ends of the cover piece 50 in the width direction are in substantially linear contact with the outdoor side surfaces of the outer wall materials 70 and 71 (contact in a linear shape extending in the vertical direction).

また、本実施形態のカバー片５０は、両外壁材７０，７１に跨って設けられており、これにより、各外壁材７０，７１の被差込板部２１，２２側の端部、各止水部材４０，４１、各被差込板部２１，２２及び隙間２３は、カバー片５０によって屋外側から覆われている。 Further, the cover piece 50 of the present embodiment is provided so as to straddle both outer wall materials 70 and 71, whereby the end portions of the outer wall materials 70 and 71 on the insertion plate portions 21 and 22 sides and the stops are provided. The water members 40 and 41, the insertion plate portions 21 and 22 and the gap 23 are covered from the outdoor side by the cover piece 50.

本実施形態の外壁構造では、カバー片５０の幅方向両端部が、外壁材７０，７１の屋外側面に略線接触しており、これにより、カバー片５０と外壁材７０，７１の表面との間から、両外壁材７０，７１の間に雨水が浸入することが抑制されている。ただし、カバー片５０と両外壁材７０，７１との接触面積は小さいため、各外壁材７０，７１の表面とカバー片５０との間からカバー片５０の屋内側に雨水が浸入する可能性はある。しかし、本実施形態では、各外壁材７０，７１と対応する被差込板部２１，２２との間が、止水部材４０，４１によってシールされているため、カバー片５０の屋内側に雨水が入り込んだとしても、この雨水は外壁材７０，７１と被差込板部２１，２２との間から屋内側に浸入し難い。 In the outer wall structure of the present embodiment, both ends in the width direction of the cover piece 50 are substantially in line contact with the outdoor side surfaces of the outer wall materials 70 and 71, whereby the cover piece 50 and the surfaces of the outer wall materials 70 and 71 are brought into contact with each other. From between, rainwater is suppressed from entering between both outer wall materials 70 and 71. However, since the contact area between the cover piece 50 and both outer wall materials 70 and 71 is small, there is a possibility that rainwater may infiltrate the indoor side of the cover piece 50 from between the surface of each outer wall material 70 and 71 and the cover piece 50. be. However, in the present embodiment, since the space between the outer wall materials 70 and 71 and the corresponding insertion plate portions 21 and 22 is sealed by the water blocking members 40 and 41, rainwater is placed on the indoor side of the cover piece 50. Even if siding enters, it is difficult for this rainwater to enter the indoor side from between the outer wall materials 70 and 71 and the insertion plate portions 21 and 22.

また、一対の被差込板部２１，２２の間に形成された縦長の隙間２３は、カバー片５０の屋内側に浸入した雨水を、流下させて屋外側に排出する流路として機能する。また、カバー材５の各止水片５３の先端部が、対応する被差込板部２１，２２に圧接することで、一対の被差込板部２２の間は、差込片５１によってシールされる。このため、一対の被差込板部２１，２２間の隙間２３に雨水が入り込んだとしても、この雨水が固定部２０において固着具９２が挿通された部分から屋内側に浸入することが抑制される。 Further, the vertically long gap 23 formed between the pair of insertion plate portions 21 and 22 functions as a flow path for allowing rainwater that has entered the indoor side of the cover piece 50 to flow down and being discharged to the outdoor side. Further, the tip of each water stop piece 53 of the cover material 5 is pressed against the corresponding insertion plate portions 21 and 22, so that the pair of insertion plate portions 22 are sealed by the insertion piece 51. Will be done. Therefore, even if rainwater enters the gap 23 between the pair of insertion plate portions 21 and 22, it is suppressed that the rainwater enters the indoor side from the portion where the fastener 92 is inserted in the fixing portion 20. To.
