【発明が属する技術分野】
本発明は、外壁材間の目地構造に関する。
【０００２】
【従来技術】
図６は、従来のこの種目地構造の一例を示すもので、図７に示すように、連結柱２１の側面にゴム又はゴム様弾性体のスポンジよりなるプレート２２を取付けたのち、外壁材２３の端部を置き、外壁材２３の側端面より突出する固定用金具２４をプレート２２を介して連結柱２１にビス２５を捩込んで固定する。ついで図８に示すように、別の外壁材２３の端部を側端面が一定の間隔を存するように向き合わせて置き、固定用金具２４を連結柱２１に同様にしてビス止めする。その後、外壁材２３、２３間の目地２５に図６に示すように目地材２６を挿入しシールしていた。
【０００３】
目地構造の別の例として、図９に示すように、下地材２７に嵌合部２８により形成される嵌合凹溝２８ｂを備えたベース目地２９を固定し、該ベース目地２９の嵌合部２８の両側に外壁材３１を配置固定したのち、外壁材間の目地３２に目地材３３を装着し、その嵌合凸片３４を嵌合凹溝２８ｂに挿入して、嵌合凸片３４先端の膨大係止部３５を嵌合部２８の係止凸片２８ａに係止させるようにしたものが開示されている（例えば特許文献１参照）。

【０００５】
【発明が解決しようとする課題】
図６〜図８に示すタイプのものでは、外壁材２３の端面より突出する固定用金具２４にビス２５を捩込むことによって外壁材２３を連結柱２１に容易に固定することができ、また外壁材２３を取換える際も、目地材２６を取外すと、ビス２５が露出するため取外し作業も容易に行える利点がある。
【０００６】
また図９に示すものでは、嵌合凹溝２８ｂに嵌合凸片３４を挿入することによって目地材３３の奥行き方向及び目地幅方向への位置決めが行われて装着された目地材の納まりがよく、外観性が向上し、また膨大係止部３５が係止凸片３６に係止することにより目地材３３が抜け止めされて、寒冷時に外壁材が収縮し、目地幅が広がっても目地材３３の脱落が防止される利点がある。
【０００７】
本発明は、図６〜図８に示すタイプのものにおいて、外壁材の取付けや取外し作業の容易性を損なうことなく、また目地材を特許文献１に開示されるように目地に位置決めして脱落することなく装着できるようにしたもので、そのための目地構造を提供することを目的とする。
【０００８】
【課題の解決手段】
請求項１に係わる発明は、図１〜図５に示すように、連結柱８の側面に連結柱８の長手方向に沿って固定される目地受材１、１６と、該目地受材１、１６の両側に配設固定された外壁材９の端面間の目地１４に装着される目地材２からなり、外壁材９の固定が外壁材９の端面より突設される固定部１２を連結柱８に止着手段１３で止着することによって行われ、また目地受材１、１６が目地幅より幅広の細長板状のプレート部３、１７と、該プレート部３、１７の中央に長手方向に沿って突出形成され、断面略Ｕ形状をなす嵌合部５、１８を備え、嵌合部５、１８が、外壁材端面より突出する上記固定部１２が収まる切欠部４を有している一方、目地材２は、目地受材１、１６の嵌合部５、１８により形成された嵌合凹溝５ｃ、１８ｃに嵌挿される突部２ｃを有し、該突部２ｃを嵌合凹溝５ｃ、１８ｃに嵌挿したとき、突部２ｃに形成される係止部２ｄが嵌合部５、１８に形成される被係止部５ｂ、１８ｂに係止し、抜け止めされて連結されるようになっており、連結柱８に目地受材１、１６、外壁材端部の順に重ねて固定部１２を連結柱８に止着手段１３で止着し、ついで外壁材端面間の目地１４に目地材２を目地受材１、１６に連結させて装着したことを特徴とする。
【０００９】
本発明によると、外壁材を連結柱に固定するときには、固定部を止着手段で止着することにより、また外壁材を取換等のため取外すときには、目地材を取外したのち止着手段を取外すことにより行われ、外壁材より突設される固定部は嵌合部の切欠部に収まるようになっているため、嵌合部が固定部と干渉することはない。また目地材は、切欠部においては固定部上にあって目地に装着されただけの状態となるが、切欠部両側では嵌合部に連結されるため抜け出しを生ずることはなく、目地への位置決めも支障なく行うことができる。
【００１０】
本発明で用いる固定部は、好ましくは金属製であるが、硬質樹脂や木質系のものであってもよい。
止着手段としては、釘を用いることもできるが、好ましくは捩込み或いは弛めることにより取付けや取外しの容易なビスが用いられる。
【００１１】
目地受材の嵌合部は、目地幅より狭いものであっても良いが、好ましくは外幅が目地幅と同一幅に形成される。外壁材をその端面が嵌合部に当たるようにして装着することにより、外壁材装着時の位置決めが行われ、目地幅を一定にして目地を均一にし、目地材によるシール性を均一にし、確実にすることができる。
【００１２】
切欠部の長手方向の幅は少なくとも固定部一枚分の長手方向の幅と同一幅以上に形成されるが、対向する外壁材より突設される固定部二枚が互いに重なり合うことなく、並べた際に共に納まりうるように、固定部長手方向の幅の二倍以上に形成してもよい。
係止部と被係止部としては、目地材の突部を目地受材の嵌合部に嵌挿したとき係止部と被係止部が係止して目地材の抜け止めが行われるようなものであればどのようなものでもよい。こうしたものとしては、例えば図９に示すような膨大係止部３５と係止凸片３６であってもよい。
【００１３】
請求項２に係わる発明は、請求項１に係わる発明において、目地受材１６のプレート部１７の一部又は全体がスポンジで形成されることを特徴とする。
外壁材端部がプレート部のスポンジ部分に押付けられて弾接することによりプレート部と外壁材とのシール性が向上する。
【００１４】
請求項３に係わる発明は、請求項２に係わる発明において、スポンジが独立気泡であることを特徴とする。
スポンジを独立気泡とすることにより、連続気泡のものよりさらにシール性が向上する。
【００１５】
請求項４に係わる発明は、請求項１〜３に係わる発明において、目地受材１のプレート部３には、外壁材端部と接触する部分に少なくとも一以上の突起又はリップ６を目地受材の長手方向に突設したことを特徴とする。
外壁部端部が突起又はリップを押付けて弾接した状態で固定されることにより、シール性を向上させることができる。
【００１６】
【発明の実施の形態】
図１は、本発明に係わる目地構造で使用する目地受材１の斜視図を示すものであり、図２は図１に示す目地受材１の断面を示すもので、同図には目地受材１に連結される目地材としてのガスケット２が併せて図示されている。
【００１７】
目地受材１は、後述する目地幅より幅広で、連結柱８の幅より若干狭い細長板状をなすプレート部３と、プレート部中央に長手方向に突設され、両側に後述する固定部１２の二倍以上の幅を有する切欠部４を形成した断面略Ｕ形状をなす嵌合部５とよりなり、嵌合部両側のプレート部３には嵌合部５に向かって斜めに突出するリップ６が突出形成され、また嵌合部５は中間部がブリッジ５ａによって連結されて剛性を高め、開口端には内向きに被係止部としての爪５ｂが形成され、上部に嵌合凹溝５ｃが形成されている。そしてリップ６を除く部分が硬質ゴム又は樹脂製で、リップ６は軟質ゴム又はゴム様弾性体よりなり、全体が押出成形品よりなっている。
【００１８】
目地材としてのガスケット２は、外壁材間の目地を覆う被覆部２ａと、外壁材の端面に弾接するリップ部２ｂと、嵌合凹溝５ｃに嵌挿される突部２ｃと、該突部２ｃに突出形成され、嵌合部５の爪５ｂに係止する係止部としての鉤部２ｄを有し、全体がゴム又はゴム様弾性体の押出成形品よりなっている。
【００１９】
外壁材の施工時には、図３及び図４に示すように、先ず連結柱８の側面に、その長手方向に沿って目地受材１のプレート部３を粘着テープにて接着又は釘にて止着して固定する。その後、嵌合部５の片側に外壁材９を配設する。外壁材９は端部裏面に鋼板１１を添設し、側方に適宜の間隔を存して突出形成される一対の固定部１２を外壁材端面より突出しており、目地受材１への配設は、固定部１２が嵌合部５の切欠部４内に挿入され、外壁材端面が嵌合部５に当たるようにして行われ、嵌合部５に当たることにより位置決めされる。
次に、従来例である図７及び図８で説明したときと同様の位置関係となるように、固定部１２同士が重ならないように上下にずらして配設して外壁材９を連結柱８に固定する（図示しない）。
【００２０】
目地受材１への配設後、固定部１２に形成したビス孔を通して止着手段としてのビス１３をプレート部３と、連結柱８に外壁材端部に圧着し、外壁材９との間をシールする。同様にして嵌合部５のもう一方の片側に外壁材９を固定部１２が重ならないようにして配設し、固定部１２をビス１３にて固定する。こうして外壁材間には、嵌合部５の幅に相当する目地１４が形成され、この目地に目地材としてのガスケット２を装着する。装着は、突部２ｃを嵌合凹溝５ｃに、鉤部２ｄが爪５ｂに係止するまで押し込んで行われ（図４）、装着によりリップ部２ｂが外壁材端面に弾接して該端面との間をシールする。なお、切欠部４内の突部２ｃは、図３に示すように嵌合部５に支持されることなく、ビス１３に当たった状態又は、ビス１３とわずかな隙間を隔てた状態となる。
【００２１】
本実施形態の目地構造によると、外壁材９を連結柱８に固定する固定部１２が外壁材端面より側方に突出しているため、連結柱８へのビス止めやビス１３の取外しが容易となり、外壁材９の取付け及び取外し作業が容易に行えること、外壁材９を嵌合部５に当たるようにして配設することにより、外壁材９の位置決めが行われ、目地幅を一定に設定できること、外壁材９を固定したとき、外壁材端部が目地受材１のリップ６を押圧することにより目地受材１とのシール性が向上すること、ガスケット２は突部２ｃを嵌合凹溝５ｃに嵌挿することにより奥行方向及び目地幅方向の位置決めが行われ、ガスケット２が直線状に外観性よく装着できるようになること、装着後は鉤部２ｄが爪５ｂに係止することにより抜け止めされ、外壁材９の収縮により目地幅が広がるようなことがあっても脱落するようなことがないこと、固定部１２が嵌合部５の切欠部４に納まり、嵌合部５との干渉が避けられるため、外壁材９を連結柱８に固定するのに何ら支障を生じることがないこと、目地受材２は硬質ゴムよりなり、剛性が比較的大きいため、釘や接着テープなどで連結柱８に部分的に固定することができ、取付工数が低減できることなどの効果を奏する。
【００２２】
図５に示す目地受材１６は、プレート部１７がゴム又はゴム様弾性体の比重が０．２〜１．０の独立気泡のスポンジよりなり、嵌合部１８が硬質ゴム又は樹脂製で、嵌合部５と同様に形成され、開口端に被係止部としての爪１８ｂを有すると共に、中間部にブリッジ１８ａを有し、全体が押出成形品よりなっている。また、嵌合部１８により嵌合凹溝１８ｃが形成される。比重が０．２未満であると、連続押出成形が困難になる一方、比重が１．０を越えると、段差部分に対するシール性が悪化する。この目地受材１６には、プレート部１７に前述の目地受材１のようにプレート部３にリップ６は形成されていないが、外壁材９が前述するようにして固定されると、外壁材端部がスポンジ製のプレート部１７に押付けられて弾接し、シールされるようになる。こうした目地受材１６を用いても上述する目地構造と同様の効果を奏する。
【００２３】
【発明の効果】
請求項１に係わる発明によると、外壁端面より突出する固定部を連結柱に止着手段によって止着し、或いは止着手段を取外すことによって外壁材の取付けや取外作業が容易に行えること、目地材は突部を嵌合部に嵌挿することにより、奥行方向及び目地幅方向への位置決めが行われ、目地材が直線性を持って外観性よく装着されうるようになること、装着後は係止部が被係止部に係止されることにより抜け止めされ、目地幅が変動しても脱落を防止できること、外壁材を連結柱に固定するための固定部が嵌合部の切欠部に納まり、嵌合部との干渉が避けられるため、外壁材を連結柱に支障なく固定できること等の効果を奏する。
【００２４】
請求項２に係わる発明によると、外壁材を固定したとき、外壁材端部がプレート部のスポンジ部分に押付けられて弾接するようになることにより、プレート部と外壁材とのシール性が向上する。
請求項３に係わる発明によると、スポンジを独立気泡としたため、シール性がさらに向上する。
請求項４に係わる発明によると、外壁材を固定したときリップが外壁材端部に強く押付けられるようになり、外壁材とのシール性が向上する。

[0016]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a perspective view of a joint receiving material 1 used in the joint structure according to the present invention, and FIG. 2 shows a cross section of the joint receiving material 1 shown in FIG. A gasket 2 as a joint material connected to the material 1 is also shown.
[0017]
The joint receiving material 1 has a plate portion 3 having an elongated plate shape that is wider than the joint width described later and slightly narrower than the width of the connecting column 8, and a fixing portion 12 that protrudes in the longitudinal direction at the center of the plate portion and is described later on both sides. Lip that protrudes obliquely toward the fitting portion 5 on the plate portions 3 on both sides of the fitting portion. 6 is formed in a projecting manner, and the fitting part 5 is connected at its middle part by a bridge 5a to increase rigidity. A claw 5b as a locked part is formed in the opening end inwardly, and a fitting groove is formed at the upper part. 5c is formed. The portion excluding the lip 6 is made of hard rubber or resin, the lip 6 is made of soft rubber or rubber-like elastic body, and the whole is made of an extruded product.
[0018]
The gasket 2 as the joint material includes a covering portion 2a that covers the joint between the outer wall materials, a lip portion 2b that elastically contacts the end surface of the outer wall material, a protrusion 2c that is inserted into the fitting groove 5c, and the protrusion 2c. And has a flange portion 2d as a locking portion that locks to the claw 5b of the fitting portion 5, and the whole is made of an extruded product of rubber or a rubber-like elastic body.
[0019]
When constructing the outer wall material, as shown in FIGS. 3 and 4, first, the plate portion 3 of the joint receiving material 1 is adhered to the side surface of the connecting column 8 along the longitudinal direction thereof with an adhesive tape or fixed with a nail. And fix. Thereafter, the outer wall material 9 is disposed on one side of the fitting portion 5. The outer wall material 9 has a steel plate 11 attached to the rear surface of the end portion, and a pair of fixing portions 12 that protrude from the side with an appropriate interval project from the end surface of the outer wall material. The fixing portion 12 is inserted into the cutout portion 4 of the fitting portion 5 so that the end face of the outer wall material hits the fitting portion 5 and is positioned by hitting the fitting portion 5.
Next, in order to achieve the same positional relationship as described with reference to FIGS. 7 and 8, which are conventional examples, the outer wall material 9 is arranged by shifting it up and down so that the fixing portions 12 do not overlap each other. (Not shown).
[0020]
After the placement on the joint receiving material 1, screws 13 as fastening means are pressed against the plate portion 3 and the connecting pillar 8 at the end of the outer wall material through the screw holes formed in the fixing portion 12, and between the outer wall material 9 To seal. Similarly, the outer wall material 9 is disposed on the other side of the fitting portion 5 so that the fixing portion 12 does not overlap, and the fixing portion 12 is fixed with screws 13. Thus, a joint 14 corresponding to the width of the fitting portion 5 is formed between the outer wall materials, and the gasket 2 as the joint material is attached to the joint. The mounting is performed by pushing the protrusion 2c into the fitting concave groove 5c until the flange 2d is locked to the claw 5b (FIG. 4), and the mounting causes the lip 2b to elastically contact the end surface of the outer wall material and the end surface.

In addition, the protrusion 2c in the notch 4 is not supported by the fitting portion 5 as shown in FIG. 3, but is in a state where it hits the screw 13 or is separated from the screw 13 by a slight gap.
[0021]
According to the joint structure of the present embodiment, since the fixing portion 12 that fixes the outer wall material 9 to the connecting column 8 protrudes laterally from the end surface of the outer wall material, it is easy to fix the screw to the connecting column 8 and remove the screw 13. The outer wall material 9 can be easily attached and removed, and the outer wall material 9 is positioned so as to contact the fitting portion 5 so that the outer wall material 9 can be positioned and the joint width can be set constant. When the outer wall member 9 is fixed, the end of the outer wall member presses the lip 6 of the joint receiving member 1 to improve the sealing performance with the joint receiving member 1, and the gasket 2 fits the protrusion 2c into the recessed groove 5c. The gasket 2 is positioned in the depth direction and the joint width direction by being inserted into the gasket 2 so that the gasket 2 can be mounted in a straight line with good appearance, and after the mounting, the hook portion 2d is locked by the claw 5b. Stopped and contraction of outer wall material 9 Even if the joint width may be further widened, it will not drop off, and the fixing portion 12 will fit in the cutout portion 4 of the fitting portion 5 and interference with the fitting portion 5 will be avoided. There is no trouble in fixing 9 to the connecting column 8, and the joint receiving material 2 is made of hard rubber and has a relatively high rigidity, so it is partially fixed to the connecting column 8 with a nail or adhesive tape. It is possible to achieve the effects of reducing the number of mounting steps.
[0022]
In the joint receiving material 16 shown in FIG. 5, the plate portion 17 is made of a closed-cell sponge having a specific gravity of 0.2 to 1.0 of rubber or a rubber-like elastic body, and the fitting portion 18 is made of hard rubber or resin. It is formed in the same manner as the fitting portion 5, has a claw 18 b as a locked portion at the opening end, and has a bridge 18 a at the intermediate portion, and is entirely made of an extruded product. In addition, a fitting groove 18 c is formed by the fitting portion 18. When the specific gravity is less than 0.2, continuous extrusion molding becomes difficult. On the other hand, when the specific gravity exceeds 1.0, the sealing performance for the stepped portion is deteriorated. In this joint receiving material 16, the lip 6 is not formed on the plate portion 3 as in the joint receiving material 1 described above, but when the outer wall material 9 is fixed as described above, the outer wall material is formed. The end portion is pressed against the sponge plate portion 17 to be elastically contacted and sealed. Even if such a joint receiving material 16 is used, the same effect as the joint structure described above is obtained.
