Description

【０００１】
【技術分野】
本発明は，四方合決り構造の外壁板，及び該外壁板を馬乗り目地状に施工してなる外壁施工構造に関する。
【０００２】
【従来技術】
従来より，図２２，図２３に示すごとく，複数の四方合決り構造の外壁板８（図２５）を馬乗り目地状に施工してなる外壁施工構造８０がある。
即ち，上記外壁板８は，図２５に示すごとく，上部下実８１０と下部上実８２０と左右に設けた横下実８４０及び横上実８３０とを有する。そして，下側の外壁板８の上部下実８１０に，上側の外壁板８の下部上実８２０を重ね，左側の外壁板８の横下実８４０に右側の外壁板８の横上実８３０を重ねて施工する。そして，上記外壁施工構造８０においては，図２２に示すごとく，左右に隣り合う上記外壁板８の間に形成される縦目地８７は，一直線状に連続せずに，左右の位置が互い違いとなる馬乗り目地状となっている。
【０００３】
上記外壁施工構造８０においては，図２３，図２４に示すごとく，上記縦目地８７の上端部及び下端部に，留め付け金具９を配置して，各外壁板８を胴縁等の下地材３に固定している。
上記留め付け金具９は，図２６に示すごとく，上記外壁板８の裏側面１６に当接する基板部９１と，該基板部９１の前方に水平方向に立設された支承部９２と，該支承部９２の前端部から斜め上方へ屈曲した上板係止部９３と，上記支承部９２の前端部から斜め下方へ屈曲した下板係止部９４と，上記上板係止部９３及び下板係止部９４の各先端部の間に連設された前方平板部９７とを有する。
【０００４】
そして，上記留め付け金具９は，図２３，図２４に示すごとく，上下の外壁板８を下地材３に固定している。即ち，上記留め付け金具９は，下板係止部９４を下側の外壁板８の上辺部８１に係止させ，上記支承部９２により上側の外壁板８を支承すると共に上板係止部９３を上側の外壁板８の下辺部８２に係止させた状態で，ビス４によって下地材３に固定されている。
【０００５】
また，図２３，図２４に示すごとく，上記外壁板８の上部下実８１０及び横下実８４０には，コーキング材８９を打設してある。このコーキング材８９の上から，他の外壁板８の下部上実８２０そして横上実８３０が重なり，上記コーキング材８９を押圧する。これにより，縦目地８７或いは横目地８７０から外壁施工構造８０の内部への漏水を防いでいる。
【０００６】
【解決しようとする課題】
しかしながら，上記外壁施工構造８０には，上記コーキング材８９を打設しているにもかかわらず，以下に示す不具合により，内部への漏水を確実に防ぐことが困難であるという問題がある。この問題につき，図２４，図２７を用いて説明する。
【０００７】
なお，図２７は，上記縦目地８７の下端部周辺を前方（表面側）から見た状態を示す。図２７において，各外壁板８の後方部分の輪郭は，実際には前方から見えない部分であり，破線で表している。そして，符号ａ_１〜ｃ_１を付した破線で輪郭を示した外壁板の後方部分は，それぞれ符号ａ_２〜ｃ_２を付した実線で輪郭を示した外壁板の前方部分と一体的になっている。また，符号８ａ〜８ｃは，それぞれ，後方部分の輪郭ａ_１〜ｃ_１と前方部分の輪郭ａ_２〜ｃ_２とを有する外壁板を表す。
【０００８】
図２４，図２７に示すごとく，上記外壁施工構造８０においては，上記縦目地８７に雨水６が入り込むことがある。具体的には，上記縦目地８７に入り込んだ雨水６は，横下実８４０に打設されたコーキング材８９によって，左右方向（図２４，図２７においては右方）への移動が阻止され，外壁施工構造８０の内部への浸入が防止される。
そのため，上記雨水６は，上記縦目地８７を伝って下方へ流下する。そして，雨水６は，上記縦目地８７の下端部に配置された上記留め付け金具９の前方平板部９７へ達する。
【０００９】
上記前方平板部９７へ達した雨水６は，その流量が少ない場合には，その殆どが，上記縦目地８７の下方に存在する外壁板８の上部下実８１０に打設されたコーキング材８９を乗り越える。そして，雨水６は上記外壁板８の上辺部８１から前方へ排出される。
【００１０】
しかし，上記雨水６の流量が多いと，上記縦目地８７を伝って流下してきた雨水６の一部は，上記コーキング材８９を乗り越えることができない。即ち，上記外壁板８の下部上実８２０と上記コーキング材８９との間の隙間は，極めて狭いため，大量の雨水６がコーキング材８９を乗り越えることは困難である。
【００１１】
その結果，上記下側の外壁板８の上辺部８１において，雨水６の圧力が高まり，雨水６を左右方向へ流動させる力が働く。そのため，図２４，図２７に示すごとく，上記外壁板８の上部下実８１０におけるコーキング材８９に達した雨水６の一部は，該コーキング材８９に沿って左右へ流れる。そして，この雨水６は，外壁板８の裏側へ浸入するおそれがある。
【００１２】
また，上記縦目地８７から上記前方平板部９７へ流下してきた雨水６の一部は，図２４，図２７に示すごとく，上記前方平板部９７の前面を伝って左右に流れる。そして，留め付け金具９の側端部９９から下側の外壁板８の上辺部８１に流下し，更には，外壁板８の裏側へ浸入するおそれがある。
【００１３】
また，上記前方平板部９７を伝って左右に移動した雨水６の一部は，上記上板係止部９３を乗り越えて上記支承部９２の上，更にはその両側端部９９へと移動する。そして，この雨水６も，上記留め付け金具９の側端部９９から上記外壁板８の裏側へ浸入する。
これにより，上記外壁板８や下地材３の腐食，劣化を招くおそれがある。
【００１４】
本発明は，かかる従来の問題点に鑑みてなされたもので，漏水を確実に防止することができる外壁板，及びこれを用いた外壁施工構造を提供しようとするものである。
【００１５】
【課題の解決手段】
第１の発明は，上部下実，下部上実，横下実，及び横上実を有する四方合決り構造の外壁板において，
該外壁板は，上記上部下実の前面に，上方から流下してくる雨水を上記外壁板の前方へ導く排水凹陥部を設けてなり，
該排水凹陥部は，上記上部下実の基端部よりも下方まで形成されていることを特徴とする外壁板にある（請求項１）。
【００１６】
上記外壁板は，上記上部下実の前面に，上記排水凹陥部を設けてなる。そのため，上記外壁板の上方から流下してくる雨水を，上記排水凹陥部により受けることができる。そして，その雨水を前方へ導いて排出することができる。
このように，上記雨水を積極的に前方へ排出することができるため，多量の雨水が上記外壁板の上部下実に流下してきても，該外壁板の裏側面へ雨水が回り込むことを防ぐことができる。従って，上記外壁板を用いることにより，漏水を確実に防止することができる。
【００１７】
以上のごとく，本発明によれば，漏水を確実に防止することができる外壁板を提供することができる。
【００１８】
第２の発明は，上部下実，下部上実，横下実，及び横上実を有する四方合決り構造の外壁板を複数用いて，馬乗り目地状に施工してなる外壁施工構造において，
上記外壁板は，上記上部下実の前面に，上方から流下してくる雨水を上記外壁板の前方へ導く排水凹陥部を設けてなり，
かつ，左右に隣り合う外壁板の間に形成される縦目地の下方には，これら左右の外壁板の下側に配設される外壁板の上記排水凹陥部が配置されていることを特徴とする外壁施工構造にある（請求項３）。
【００１９】
上記外壁施工構造においては，上記縦目地の下方に，下側の外壁板の排水凹陥部が配置されている。そのため，上記縦目地を伝って流下してくる雨水を，上記外壁板の排水凹陥部によって受けることができる。そして，その雨水を前方へ導いて排出することができる。
このように，上記雨水を積極的に前方へ排出することができるため，多量の雨水が上記縦目地を伝って，下側の外壁板の上部下実に流下してきても，該外壁板の裏側面へ雨水が回り込むことを防ぐことができる。従って，上記外壁施工構造は，内部への漏水を確実に防止することができる。
【００２０】
以上のごとく，本発明によれば，漏水を確実に防止することができる外壁施工構造を提供することができる。
【００２１】
【発明の実施の形態】
上記第１の発明（請求項１）において，上記四方合決り構造の外壁板とは，上辺部に上部下実を，下辺部に下部上実を，左辺部に横上実を，右辺部に横下実をそれぞれ有する外壁板である（図１参照）。そして，下側の外壁板の上部下実に，上側の外壁板の下部上実を重ね，左側の外壁板の横下実に右側の外壁板の横上実を重ねて施工する。
【００２２】
また，上方から流下してくる雨水としては，例えば，上記外壁板の上側に配された隣合う２枚の外壁板の間に形成された，縦目地を伝って流下してくる雨水がある。
また，上記外壁板の前方とは，例えば，上記外壁板を建築物の構造躯体に施工した際に，建築物の外側を向く方向をいう。
【００２３】
また，上記上部下実は，その前面にコーキング材を打設してなり，かつ該コーキング材は，上記排水凹陥部の左右において途切れていることが好ましい（請求項２）。この場合には，上記コーキング材が雨水の排出を妨げることがなく，一層確実に，雨水を前方へ排出し，漏水を防ぐことができる。
【００２４】
また，上記排水凹陥部は，上記上部下実の基端部よりも下方まで形成されている。これにより，一層多量の雨水が，上記外壁板の上部下実に流下してきても，確実に雨水を前方へ排出し，漏水を防止することができる。
【００２５】
次に，上記第２の発明（請求項３）において，馬乗り目地状とは，外壁施工構造の上端から下端にかけて上記縦目地が一直線状に連続せず，例えば上記縦目地の左右位置が互い違いとなる状態をいう（図４参照）。
【００２６】
また，上記縦目地の下端部には，留め付けシール金具が配設してあり，
上記留め付けシール金具は，上記外壁板の裏側面に当接する基板部と，該基板部から前方へ水平方向に立設された中央水平立設部と，該中央水平立設部の前端から下方へ屈曲した下方屈曲部と，該下方屈曲部の左右において上記中央水平立設部の前端から斜め上方へ屈曲した上方屈曲部と，該上方屈曲部の上端から下方へ屈曲した前板部と，上記中央水平立設部の左右において上記基板部から前方へ水平方向に立設された支承部と，該支承部の前端から上方へ屈曲した上板係止部と，上記支承部の前端から下方へ屈曲した下板係止部と，上記上板係止部の先端から上記下板係止部の先端にかけて垂直方向に連設された連設部とを有し，更に，上記中央水平立設部の左右端部と上記上方屈曲部の上面，及び上記前板部の前面には，弾性材が配設されており，
また，上記留め付けシール金具は，上記基板部を上記外壁板の裏側面に当接させて，胴縁等の下地材に固定されており，
上記留め付けシール金具の下側に配置した上記外壁板は，上辺部を上記留め付けシール金具の下板係止部に係止させ，上側に配置した上記外壁板は，下辺部を上記留め付けシール金具の上記支承部に載置すると共に上記上板係止部に係止させてあり，
また，上記留め付けシール金具の上記弾性材は，上側の上記外壁板の下辺部に密着しており，
かつ，上記縦目地の下端部は，上記留め付けシール金具における上記左右の弾性材の間に配置されていることが好ましい（請求項４）。
【００２７】
この場合には，上記縦目地の下端部が，上記留め付けシール金具における上記左右の弾性材の間に配置されている。そのため，上記縦目地を伝って流下してくる雨水を上記左右の弾性材の間における上記中央水平立設部によって受けることができる。そして，この雨水を，上記下方屈曲部から，下側の外壁板の上記排水凹陥部へ確実に導くことができる。
【００２８】
また，上記中央水平立設部の左右端部と上記上方屈曲部の上面，及び上記前板部の前面に配設された弾性材は，上記留め付けシール金具の上側に配置する外壁板の下辺部に密着している。それ故，上記中央水平立設部に流下した雨水を，左右の上記弾性材により堰き止め，外壁施工構造の内部への浸入を確実に防ぐことができる。そして，堰き止められた雨水を，上記下方屈曲部から上記排水凹陥部へ導き，外壁前方へ積極的に排出することができる。
【００２９】
また，上記留め付けシール金具は上記下地材に固定され，下方に配置した上記外壁板は，上辺部を上記留め付けシール金具の下板係止部に係止させ，上方に配置した上記外壁板は，下辺部を上記留め付けシール金具の上記支承部に載置すると共に上記上板係止部に係止させてある。
これにより，上記留め付けシール金具によって，上記外壁板を胴縁等の下地材に，容易かつ確実に留め付けることができる。
【００３０】
即ち，上記留め付けシール金具は，漏水防止と，外壁板の留め付けとの双方の機能を有する。そのため，上記留め付けシール金具を用いることにより，漏水を防ぐ外壁施工構造を容易かつ安価に施工することができる。
【００３１】
また，上記弾性材は，弾力性があり，かつ防水性のあるものである。
また，本明細書においては，「前」とは建築物の外側方向を，「後」とは建築物の内側方向をいう。そして，上記留め付けシール金具等に関しては，下地材に取付けた状態を基準として，「前」，「後」，「上」，「下」，「水平」，「垂直」等の表現を用いる。
【００３２】
また，上記前板部は，上記連設部よりも後方に配置されていることが好ましい。これにより，上記外壁板の下部上実を，上記前板部の前面に配設した上記弾性材に密着させると共に，上記連設部にも確実に当接させることができる。そのため，上記留め付けシール金具は，上記外壁板を安定して留め付けることができる。
【００３３】
また，上記留め付けシール金具は，上記弾性材を，上記中央水平立設部の上方の基板部にも延設してなり，該弾性材は，上記外壁板の裏側面に密着していることが好ましい（請求項５）。この場合には，上記弾性材が上記外壁板の裏側面にも密着し，雨水が上記外壁板の裏側面から外壁施工構造の内部へ浸入することを防ぐことができる。
【００３４】
また，上記縦目地の上端部には，留め付けストッパー金具が配置されており，該留め付けストッパー金具は，上記外壁板の裏側面に当接する基板部と，該基板部の前方に水平方向に立設された支承部と，該支承部の前端部から斜め上方へ屈曲した上板係止部と，上記支承部の前端部から斜め下方へ屈曲した下板係止部と，上記支承部よりも下方の上記基板部から前方に垂直方向に立設された垂直立設部とを有し，
また，上記留め付けストッパー金具は，上記基板部を上記外壁板の裏側面に当接させて，上記下地材に固定されており，
上記留め付けストッパー金具の下方に配置した上記外壁板は，上辺部を上記留め付けストッパー金具の下板係止部に係止させ，上側に配置した上記外壁板は，下辺部を上記留め付けストッパー金具の上記支承部に載置すると共に上記上板係止部に係止させてあり，
かつ，上記垂直立設部には，下側の外壁板の側端面が当接していることが好ましい（請求項６）。
【００３５】
この場合には，上記外壁板を一層正確に施工することができる。即ち，上記留め付けストッパー金具における垂直立設部により，上記留め付けストッパー金具の下側の外壁板が左右にずれることを防ぐことができる。
【００３６】
また，上記外壁板は，上記上部下実の前面にコーキング材を打設してなり，かつ該コーキング材は，上記排水凹陥部の左右において途切れていることが好ましい（請求項７）。この場合には，上記コーキング材が雨水の排出を妨げることがなく，一層確実に，雨水を前方へ排出し，漏水を防ぐことができる。
【００３７】
また，上記外壁板の排水凹陥部は，上記上部下実の基端部よりも下方まで形成されていることが好ましい（請求項８）。この場合には，一層多量の雨水が，上記外壁板の上部下実に流下してきても，確実に雨水を前方へ排出し，漏水を防止することができる。

【Technical field】
The present invention relates to an outer wall plate having a four-way joint structure and an outer wall construction structure in which the outer wall plate is constructed in a horseshoe joint shape.
[0002]
[Prior art]
Conventionally, as shown in FIGS. 22 and 23, there is an outer wall construction structure 80 in which a plurality of outer wall plates 8 (FIG. 25) having a four-way joint structure are constructed in a horse riding joint shape.
That is, as shown in FIG. 25, the outer wall plate 8 has an upper lower 810, a lower upper 820, a horizontal lower 840 and a horizontal upper 830 provided on the left and right. Then, the lower upper fruit 820 of the upper outer wall plate 8 is overlapped with the upper lower fruit 810 of the lower outer wall plate 8, and the lateral upper fruit 830 of the right outer wall plate 8 is placed on the lateral lower fruit 840 of the left outer wall plate 8. Repeat construction. And in the said outer wall construction structure 80, as shown in FIG. 22, the vertical joint 87 formed between the said outer wall board | plates 8 adjacent on the right and left does not continue in a straight line, and the position of right and left is staggered. It is a horse riding joint.
[0003]
In the outer wall construction structure 80, as shown in FIGS. 23 and 24, the fasteners 9 are arranged at the upper end and the lower end of the vertical joint 87, and each outer wall plate 8 is attached to the base material 3 such as the trunk edge. It is fixed to.
As shown in FIG. 26, the fastening bracket 9 includes a base plate portion 91 that abuts against the back side surface 16 of the outer wall plate 8, a support portion 92 that stands in front of the base plate portion 91 in the horizontal direction, and the support plate. An upper plate engaging portion 93 bent obliquely upward from the front end portion of the portion 92; a lower plate engaging portion 94 bent obliquely downward from the front end portion of the support portion 92; the upper plate engaging portion 93 and the lower plate And a front flat plate portion 97 provided continuously between the respective distal end portions of the locking portion 94.
[0004]
Then, as shown in FIGS. 23 and 24, the fastening bracket 9 fixes the upper and lower outer wall plates 8 to the base material 3. That is, the fastening bracket 9 has the lower plate engaging portion 94 engaged with the upper side portion 81 of the lower outer wall plate 8, and the upper outer wall plate 8 is supported by the support portion 92 and the upper plate engaging portion. In a state where 93 is engaged with the lower side portion 82 of the upper outer wall plate 8, it is fixed to the base material 3 with screws 4.
[0005]
Further, as shown in FIGS. 23 and 24, a caulking material 89 is placed on the upper lower shell 810 and the lateral lower shell 840 of the outer wall plate 8. From above the caulking material 89, the lower upper solid 820 and the horizontal upper solid 830 of the other outer wall plate 8 overlap to press the caulking material 89. Thereby, water leakage from the vertical joint 87 or the horizontal joint 870 to the inside of the outer wall construction structure 80 is prevented.
[0006]
[Problems to be solved]
However, the outer wall construction structure 80 has a problem that despite the placement of the caulking material 89, it is difficult to reliably prevent water leakage to the inside due to the following problems. This problem will be described with reference to FIGS.
[0007]
FIG. 27 shows a state in which the periphery of the lower end portion of the vertical joint 87 is viewed from the front (front side). In FIG. 27, the outline of the rear portion of each outer wall plate 8 is actually a portion that cannot be seen from the front, and is represented by a broken line. And the symbol a₁~ C₁The rear part of the outer wall plate, which is outlined by a broken line marked with₂~ C₂It is integrated with the front portion of the outer wall plate, which is outlined by a solid line with. Reference numerals 8a to 8c denote the contour a of the rear part, respectively.₁~ C₁And the contour a of the front part₂~ C₂The outer wall board which has these.
[0008]
As shown in FIGS. 24 and 27, rainwater 6 may enter the vertical joint 87 in the outer wall construction structure 80. Specifically, the rainwater 6 that has entered the vertical joint 87 is prevented from moving in the left-right direction (rightward in FIGS. 24 and 27) by the caulking material 89 placed on the horizontal bottom 840. Intrusion into the outer wall construction structure 80 is prevented.
Therefore, the rainwater 6 flows down along the vertical joint 87. The rainwater 6 reaches the front flat plate portion 97 of the fastener 9 disposed at the lower end portion of the vertical joint 87.
[0009]
When the flow rate of the rainwater 6 reaching the front flat plate portion 97 is small, most of the rainwater 6 is made of caulking material 89 placed on the upper lower solid 810 of the outer wall plate 8 existing below the vertical joint 87. get over. The rainwater 6 is discharged forward from the upper side portion 81 of the outer wall plate 8.
[0010]
However, if the flow rate of the rainwater 6 is large, a part of the rainwater 6 flowing down along the vertical joint 87 cannot get over the caulking material 89. That is, the gap between the lower upper shell 820 of the outer wall plate 8 and the caulking material 89 is extremely narrow, and it is difficult for a large amount of rainwater 6 to get over the caulking material 89.
[0011]
As a result, in the upper side portion 81 of the lower outer wall plate 8, the pressure of the rainwater 6 increases, and a force that causes the rainwater 6 to flow in the left-right direction works. Therefore, as shown in FIGS. 24 and 27, a part of the rainwater 6 that reaches the caulking material 89 in the upper lower solid 810 of the outer wall plate 8 flows to the left and right along the caulking material 89. The rainwater 6 may enter the back side of the outer wall plate 8.
[0012]
A part of the rainwater 6 flowing down from the vertical joint 87 to the front flat plate portion 97 flows to the left and right along the front surface of the front flat plate portion 97 as shown in FIGS. Then, it may flow from the side end portion 99 of the fastening metal 9 to the upper side portion 81 of the lower outer wall plate 8 and may enter the back side of the outer wall plate 8.
[0013]
Further, part of the rainwater 6 that has moved to the left and right along the front flat plate portion 97 gets over the upper plate locking portion 93 and moves onto the support portion 92 and further to both end portions 99 thereof. The rainwater 6 also enters the back side of the outer wall plate 8 from the side end portion 99 of the fastening bracket 9.
As a result, the outer wall plate 8 and the base material 3 may be corroded and deteriorated.
[0014]
