以下、本発明の実施形態の目地構造について図面により説明する。
図1は、本発明が対象とする目地構造を示すもので、図2及び図3に示す外壁パネル2が階上と階下においてそれぞれ、図示しない梁に組み付けられ、左右の外壁パネル間には縦目地3が、上下の外壁パネル間には横目地4が形成されている。
Hereinafter, a joint structure according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a joint structure to which the present invention is directed. The outer wall panel 2 shown in FIGS. 2 and 3 is assembled to a beam (not shown) on the upper and lower floors, and a vertical wall is provided between the left and right outer wall panels. A horizontal joint 4 is formed between the upper and lower outer wall panels.
外壁パネル2は図2及び図3に示すように、外壁面材5と、外壁面材5の左右両側縁に取付けられる胴縁6を介して重ね合わせられる断熱ボード7と、パネルフレーム1とで構成されて、これらが一体化され、胴縁6間は上下方向に貫通する通気層8となっている。 As shown in FIGS. 2 and 3, the outer wall panel 2 is composed of an outer wall material 5, a heat insulating board 7 that is overlapped via a trunk edge 6 that is attached to both left and right edges of the outer wall material 5, and a panel frame 1. These are integrated to form a ventilation layer 8 penetrating vertically between the trunk edges 6.
外壁パネル2を構成する胴縁6は、縦方向の側端面が好ましくは図2に示すように外壁面材5と面一に揃えられている。階上の外壁パネル2の胴縁6は下端面が図3に示す例では、階上の外壁パネル2の外壁面材5と面一をなしているが、外壁面材5より若干下方に突出していたり、上方に引込んで形成されていてもよい。 As for the trunk edge 6 which comprises the outer wall panel 2, the side end surface of the vertical direction is preferably aligned with the outer wall surface material 5, as shown in FIG. In the example shown in FIG. 3, the trunk edge 6 of the outer wall panel 2 on the floor is flush with the outer wall material 5 of the outer wall panel 2 on the floor, but protrudes slightly below the outer wall material 5. Or may be formed by being drawn upward.
階下の外壁パネル2は、胴縁上端が外壁面材5より下げられているが、これは傾斜部19cを備えた後述の水切板19を取付ける際に支障を生じないようにするためで、傾斜部19cの勾配を小さくすることにより、或いは傾斜面19cをなくすことにより胴縁上端を外壁パネル2と面一に揃えることも可能である。 The outer wall panel 2 of the downstairs has a trunk edge whose upper end is lowered from the outer wall material 5, but this is to prevent a hindrance when installing a water draining plate 19 having an inclined portion 19 c described later. It is possible to make the upper end of the trunk edge flush with the outer wall panel 2 by reducing the gradient of the portion 19c or by eliminating the inclined surface 19c.
上下に組付けられる外壁パネル2はまた、そのうちの少なくとも階下に組付けられる外壁パネル2の胴縁6は、上端面が外壁面材5より下がり、かつ屋外側の側面が上方より一定長さ切除されて外壁面材5との間に差込溝9が下向きに形成されている。 The outer wall panel 2 to be assembled vertically is also cut at least at the trunk edge 6 of the outer wall panel 2 to be assembled downstairs, with the upper end surface being lowered from the outer wall surface material 5 and the outdoor side surface being cut by a certain length from above. The insertion groove 9 is formed downward with respect to the outer wall surface material 5.
外壁パネル2を構成する断熱ボード7は弾力性があり、図2に示すように一部が外壁面材5より左右の側方にはみ出して突出形成されていると共に、上下に組付けられる外壁パネル2のうち、少なくとも階下に組付けられる外壁パネル2は、図3に示すように上方に一部がはみ出して突出形成され、左右に組付けられる外壁パネル2の断熱ボード7は図2に示すように圧接して密着し、上下の外壁パネル2の断熱ボード7も圧接して密着している(図3においては、上下の断熱ボード間に図示するように後述する横目地用二次止水材21の厚み分程の隙間ができているが、施工後では二次止水材21は圧縮されて断熱ボード7に埋まり、上下の断熱ボード7が近接又は密着した状態となる)。なお、階上の外壁パネル2の断熱ボード7は図示する例では、下端面が外壁面材5と面一となっているが、外壁面材5より若干下方に突出していてもよい。この場合、その分だけ階下の外壁パネル2の断熱ボード7は下方に引込められる。断熱ボード7に弾力性がない場合であっても、断熱ボード7を押付けた状態で組付けることにより同様な組付けが可能である。 The heat insulating board 7 constituting the outer wall panel 2 is elastic, and as shown in FIG. 2, a part of the heat insulating board 7 protrudes to the left and right sides of the outer wall surface material 5 and protrudes and is assembled vertically. 2, at least the outer wall panel 2 assembled below the floor is protruded and partially protrudes upward as shown in FIG. 3, and the heat insulation board 7 of the outer wall panel 2 assembled on the left and right is as shown in FIG. 2. And the heat insulation boards 7 of the upper and lower outer wall panels 2 are also in pressure contact and intimate contact (in FIG. 3, the secondary waterproofing material for horizontal joints to be described later is illustrated between the upper and lower heat insulation boards. Although a gap corresponding to the thickness of 21 is formed, the secondary waterstop material 21 is compressed and buried in the heat insulation board 7 after the construction, and the upper and lower heat insulation boards 7 are in close proximity or in close contact with each other). In the illustrated example, the heat insulating board 7 of the outer wall panel 2 on the floor has a lower end surface that is flush with the outer wall surface material 5, but may protrude slightly below the outer wall surface material 5. In this case, the heat insulation board 7 of the outer wall panel 2 on the lower floor is retracted downward accordingly. Even if the heat insulation board 7 is not elastic, the same assembling is possible by assembling the heat insulation board 7 in a pressed state.
左右の外壁パネル間の縦目地3には、縦目地用止水材としての縦目地ガスケット11が装填される。この縦目地ガスケット11は図2及び図4に示すように、柱部12と、柱部12の一端に一体形成される意匠リップ13と、該意匠リップ寄りの柱部中間部において左右に突出形成される中空シール部14と、柱部12の他端に一体形成されるシールリップ15とを備え、柱部12には必要によって芯材がインサートされる。そして上下に組付けられる外壁パネル2のうち、少なくとも階下の外壁パネル間の縦目地3に装填される縦目地ガスケット11には、図4に示すように、その上端部においてシールリップ近くの柱部12に一定深さのスリット16が下向きに形成され、スリット16より屋内側部分は立ち上がり片17となっている。図示する立ち上がり片17は上端面が他より低くなっているが、低くしないで他と同じ高さにしてもよい。 The vertical joint 3 between the left and right outer wall panels is loaded with a vertical joint gasket 11 as a water-proof material for the vertical joint. As shown in FIGS. 2 and 4, the vertical joint gasket 11 is formed to protrude left and right at the column portion 12, the design lip 13 integrally formed at one end of the column portion 12, and the column portion intermediate portion near the design lip. And a sealing lip 15 formed integrally with the other end of the column portion 12, and a core material is inserted into the column portion 12 as necessary. Of the outer wall panels 2 to be assembled vertically, at least the vertical joint gasket 11 loaded in the vertical joint 3 between the outer wall panels of the downstairs is, as shown in FIG. 12, a slit 16 having a constant depth is formed downward, and an indoor side portion of the slit 16 is a rising piece 17. The upper end surface of the rising piece 17 shown in the figure is lower than the others, but it may be the same height as the others without being lowered.
縦目地ガスケット11を縦目地3に装填するときには、常法のように縦目地3に屋外側より所定量押込み、意匠リップ13及び中空リップ14を左右両側の外壁面材5に押付け、かつシールリップ15を両側の胴縁6に押付けて取付け、シールリップ15の胴縁6への押付けにより断熱ボード7の継目18から水が屋内に浸入するのを防いでいる(図2参照)。 When the vertical joint gasket 11 is loaded into the vertical joint 3, a predetermined amount is pushed into the vertical joint 3 from the outdoor side as usual, and the design lip 13 and the hollow lip 14 are pressed against the outer wall material 5 on both the left and right sides, and the seal lip 15 is pressed against the barrel edge 6 on both sides and the seal lip 15 is pressed against the barrel edge 6 to prevent water from entering the indoor space from the joint 18 of the heat insulating board 7 (see FIG. 2).
階下の外壁パネル2を図示しない梁に組付け後、水切板19を外壁パネル2に取付ける。水切板19は図5に示すように、横長の鋼板を縦向きに折り曲げて水平部19aと、垂直部19bと、水平部19a及び垂直部19bを連結する傾斜部19cを形成してなるもので、水平部上には例えば発泡スポンジ材等よりなる横目地用二次止水材21が例えば両面テープにより接着して取付けられ、傾斜部19cには通気孔22が形成されている。この通気孔22は図示する例では長方形をなしているが、円形、楕円形その他任意の形状であってもよい。 After assembling the outer wall panel 2 below the floor to a beam (not shown), the draining plate 19 is attached to the outer wall panel 2. As shown in FIG. 5, the draining plate 19 is formed by bending a horizontally long steel plate in a vertical direction to form a horizontal portion 19a, a vertical portion 19b, and an inclined portion 19c connecting the horizontal portion 19a and the vertical portion 19b. On the horizontal portion, for example, a secondary waterproof material 21 for horizontal joint made of foamed sponge material or the like is attached by, for example, a double-sided tape, and a ventilation hole 22 is formed in the inclined portion 19c. The vent hole 22 is rectangular in the illustrated example, but may be circular, elliptical, or any other shape.
前述する水切板19の外壁パネル2上端面への取付けは、接着剤や粘着テープといった接着手段を用いて接着してもよいし、釘等の止め金具よりなる物理的な止着手段を用いて 行ってもよく、またそのような手段を用いないで単に置いておくだけでもよい。 The above-described draining plate 19 may be attached to the upper end surface of the outer wall panel 2 by using an adhesive means such as an adhesive or an adhesive tape, or by using a physical fastening means such as a fastener such as a nail. It may be done or simply left without such means.
通気孔22は一定ピッチで形成され、水切板19を外壁パネル2に取付けたとき、通気孔22が図7に示すように前述の縦目地3や胴縁6、とくに縦目地3に位置しないようにし、強風時に風が吹き込んでも水が通気孔22を通って断熱ボード7の継ぎ目18に直接吹付けられることがないようにされる。通気孔22の大きさやピッチを設定するに際し、例えば通気孔22の大きさが一定で、縦目地3及び胴縁6に通気孔22が位置しないようにするため、通気孔22のピッチが大きくなり過ぎる場合には、縦目地や胴縁6に対応する区間以外の箇所ではピッチを短くしてもよい。 The ventilation holes 22 are formed at a constant pitch, and when the draining plate 19 is attached to the outer wall panel 2, the ventilation holes 22 are not positioned at the vertical joint 3 and the trunk edge 6, particularly the vertical joint 3 as shown in FIG. 7. Thus, even when wind blows in strong wind, water is prevented from being directly blown to the joint 18 of the heat insulating board 7 through the vent hole 22. When setting the size and pitch of the air holes 22, for example, the air holes 22 have a constant size, and the air holes 22 are not positioned at the vertical joint 3 and the trunk edge 6. If it is too long, the pitch may be shortened in places other than the section corresponding to the vertical joint and the trunk edge 6.
前記横目地用二次止水材21は、図5に示す例では傾斜部側の水平部19aの一側縁に取付けられているが、水平部19aの全面に取付けてもよいし、水平部19aの中央又は他側縁に取付けてもよい。 In the example shown in FIG. 5, the secondary waterstop material 21 for horizontal joints is attached to one side edge of the horizontal portion 19a on the inclined portion side, but may be attached to the entire surface of the horizontal portion 19a or the horizontal portion. You may attach to the center or other side edge of 19a.
組付ける順序については、先ず階下の外壁パネル2が図示しない梁に組付けられ、その後に階上の外壁パネル2が同じく図示しない梁に組付けられる。階上の外壁パネルを組付けるのに先立って少なくとも横目地ガスケット24及び水切板19を階下の外壁パネル上に取付けておく必要があるが、縦目地ガスケット11については、どのタイミングで取付けてもよく、適宜に階下及び階上の縦目地3に組付けられる。以下に組付けの一例を説明するが、これに限定されるものではない。 Regarding the order of assembly, the outer wall panel 2 on the lower floor is first assembled to a beam (not shown), and then the outer wall panel 2 on the lower floor is also assembled to a beam (not shown). Prior to assembling the outer wall panel on the floor, it is necessary to attach at least the horizontal joint gasket 24 and the draining plate 19 on the outer wall panel on the lower floor. However, the vertical joint gasket 11 may be attached at any timing. As appropriate, it is assembled to the vertical joint 3 on the lower and upper floors. An example of assembly will be described below, but the present invention is not limited to this.
水切板19を外壁パネル2へ取付ける前に先ず、階下の外壁パネル2の外壁面材5上端の小口面上に横目地用一次止水材である横目地ガスケット24を装着する。横目地ガスケット24は図3に示すように、階下の外壁パネル2の外壁面材5の屋内側及び屋外側のコーナに被さる垂下片25、26を有し、外壁面材5上端の小口面への取付けは、内外の垂下片25、26内に小口面が納まるように位置決めして行われる。なお図示する横目地ガスケット24は複雑な中空断面構造をなしているが、要は外壁面材5上端の屋内側及び屋外側コーナに被さる垂下片25,26を有し、横目地4に納まって横目地4を止水する機能を有していれば、既存のどのような構造の止水材であってもよく、垂下片25、26以外の横目地ガスケット24の構造は本発明の特徴部分ではないため、具体的な構造の説明は省略する。 Before attaching the draining plate 19 to the outer wall panel 2, first, a horizontal joint gasket 24, which is a primary water-stopping material for horizontal joints, is mounted on the small edge surface at the upper end of the outer wall material 5 of the downstairs outer wall panel 2. As shown in FIG. 3, the horizontal joint gasket 24 has drooping pieces 25 and 26 covering the corners on the indoor side and the outdoor side of the outer wall surface material 5 of the downstairs outer wall panel 2, and to the small edge surface at the upper end of the outer wall surface material 5. The attachment is performed by positioning so that the fore edge surface fits in the hanging pieces 25 and 26 inside and outside. The illustrated horizontal joint gasket 24 has a complicated hollow cross-sectional structure, but in essence, it has hanging pieces 25 and 26 covering the indoor side and outdoor side corners at the upper end of the outer wall surface material 5 and is housed in the horizontal joint 4. As long as it has a function of water-stopping the horizontal joint 4, any existing water-stopping material may be used, and the structure of the horizontal joint gasket 24 other than the hanging pieces 25 and 26 is a characteristic part of the present invention. Therefore, the description of the specific structure is omitted.
横目地ガスケット24の取付け後、水切板19を取付ける。この取付けは垂直部19bを下向きにして外壁面材5と胴縁6との間の前記差込溝9に差込み、かつ前記縦目地3に装填される縦目地ガスケット11のスリット16に差込みながら横目地用二次止水材21を上側にした水平部19aを断熱ボード上端の小口面に置くことにより行われる。縦目地ガスケット11の立ち上がり片17を図示するものよりも高くした場合、水切板19の垂下部19bより上方の立ち上がり片17は、前記傾斜部19cにより屋内側に押込まれるが、前述したように傾斜部19cの勾配を小さくしたり傾斜部をなくせば、屋内側に押込まれないようにすることもできる。 After the horizontal joint gasket 24 is attached, the draining plate 19 is attached. This attachment is made with the vertical portion 19b facing downward and inserted into the insertion groove 9 between the outer wall surface material 5 and the trunk edge 6 and into the slit 16 of the vertical joint gasket 11 loaded in the vertical joint 3 while inserting the horizontal joint. This is done by placing a horizontal part 19a with the secondary secondary water blocking material 21 on the upper side on the small edge of the upper end of the heat insulation board. When the rising piece 17 of the vertical joint gasket 11 is made higher than that shown in the figure, the rising piece 17 above the hanging part 19b of the draining plate 19 is pushed into the indoor side by the inclined portion 19c. If the slope of the inclined portion 19c is reduced or the inclined portion is eliminated, it can be prevented from being pushed into the indoor side.
次に図3に示すように階上の外壁パネル2を階下の外壁パネル上に位置合わせをして断熱ボード7が水切板19の水平部19a上に横目地用二次止水材21を介して圧着されるようにして図示しない梁に組付ける。この組付けにより階下の外壁パネル2の外壁面材5上端の小口面に被せられる横目地ガスケット24が下方へ押し込まれ、横目地4を止水する。 Next, as shown in FIG. 3, the upper outer wall panel 2 is aligned with the lower outer wall panel, and the heat insulating board 7 is placed on the horizontal portion 19 a of the draining plate 19 via the secondary water stop material 21 for horizontal joints. Assemble to a beam (not shown). As a result of this assembly, the horizontal joint gasket 24 that covers the small edge surface at the upper end of the outer wall surface material 5 of the outer wall panel 2 below the floor is pushed downward, and the horizontal joint 4 is stopped.
外壁パネル1を図1に示すように左右上下に組付けた状態において、縦目地3は図2に示すように縦目地用止水材である縦目地ガスケット11が左右の外壁パネル2の外壁面材5に押付けられ、かつシールリップ15が左右の胴縁6に押付けられることにより止水され、断熱ボード7の継目18への止水を行う一方、横目地4は図3に示すように横目地用一次止水材の横目地ガスケット24と水切板19により止水されて二重の止水構造をなし、横目地ガスケット24が上下の外壁パネル2の外壁面材5で上下より押え込まれて止水すると共に、階下の外壁面材5の小口面に被さって止水を行い、また水切板19が水平部19aを上下の外壁パネル2の断熱ボード7で挟み込むことにより支持されると共に、階上の外壁パネル2の断熱ボード7が横目地用二次止水材21に圧着することにより上下の断熱ボード間を止水するようになっている。そして垂直部19bを胴縁6と外壁面材5との間の差込溝9に差し込むことで傾斜部19cが胴縁6及び通気層8を覆っている。 In the state where the outer wall panel 1 is assembled to the left and right and up and down as shown in FIG. 1, the vertical joint 3 is a vertical joint gasket 11 which is a vertical joint water-stopping material as shown in FIG. The seal 5 is pressed against the material 5 and the seal lip 15 is pressed against the left and right body edges 6 to stop the water and to stop the water to the joint 18 of the heat insulation board 7. Water is stopped by the horizontal joint gasket 24 and the draining plate 19 of the primary primary water-stopping material to form a double water-stop structure, and the horizontal joint gasket 24 is pressed from above and below by the outer wall material 5 of the upper and lower outer wall panels 2. The water is stopped by covering the small face of the outer wall material 5 below the floor, and the draining plate 19 is supported by sandwiching the horizontal portion 19a between the heat insulating boards 7 of the upper and lower outer wall panels 2, Insulation board of outer wall panel 2 on the floor There has been adapted to the water shut-off between the top and bottom of the insulation board by crimping the horizontal joint for the secondary water stop material 21. The inclined portion 19 c covers the trunk edge 6 and the ventilation layer 8 by inserting the vertical portion 19 b into the insertion groove 9 between the trunk edge 6 and the outer wall surface material 5.
縦目地3と横目地4が交差する交差部分では、図7に示すように水切板19の垂直部19bが縦目地ガスケット11のスリット16に差し込まれ、スリット16より下方の水切板19の垂直部19bが届かない止水構造と同様、シールリップ15による止水構造を立ち上がり片17で維持させながら止水板19を設置することができるようになっている。また止水板19の垂直部19bで位置を規制された立ち上がり片17によりシールリップ15も位置を規制された状態で両側の胴縁6に押付けられて止水機能を果たし、断熱ボード7の継目18への止水を行う。 At the intersection where the vertical joint 3 and the horizontal joint 4 intersect, as shown in FIG. 7, the vertical portion 19 b of the drainage plate 19 is inserted into the slit 16 of the vertical joint gasket 11, and the vertical portion of the drainage plate 19 below the slit 16. Similarly to the water stop structure that does not reach 19b, the water stop plate 19 can be installed while the water stop structure by the seal lip 15 is maintained by the rising piece 17. Further, the seal lip 15 is pressed against the body edges 6 on both sides in a state where the position is restricted by the rising piece 17 whose position is restricted by the vertical portion 19 b of the water stop plate 19, and performs a water stop function. Stop water to 18.
縦目地ガスケット11の意匠リップ13より屋内側に侵入し、更に中空シール部14をも通過して侵入した水は中空シール部14の奥行き幅と同程度の距離を置いて屋内側に設けられたシールリップ15に遮られる。例えば階上の縦目地3においてシールリップ15にまで届いた水はシールリップ15の屋外側の縦目地ガスケット内を伝い落ち、水切板19の傾斜部19c上に滴り落ちたのち、階下の縦目地3内を伝い落ちるか、傾斜部19cを横向きに伝って通気孔22に達し、或いは差込溝9を横向きに伝って通気層8内に滴下し、排出されるようになる。 The water that entered the indoor side from the design lip 13 of the vertical joint gasket 11 and further passed through the hollow seal portion 14 was provided on the indoor side at a distance approximately the same as the depth width of the hollow seal portion 14. It is blocked by the seal lip 15. For example, water that has reached the seal lip 15 in the vertical joint 3 on the floor falls down in the vertical joint gasket on the outdoor side of the seal lip 15 and drops on the inclined portion 19c of the draining plate 19, and then the vertical joint on the lower floor. 3, or travels down the inclined portion 19 c sideways to reach the vent hole 22, or travels sideways through the insertion groove 9 and drops into the vent layer 8 to be discharged.
本実施形態の目地構造によると、横目地4は横目地用一次止水材である横目地ガスケット24と水切板19とで止水され、二重に止水されるようになること、水切板19は水平部19aが上下の外壁パネル2の断熱ボード7で挟み付けられることにより支持され、水切板19と支持するために水切板19や外壁パネル2を特別な構造にしたり、取付器具を設ける必要がなく、また取付時の工数が増えることもなく、施工が容易であること、上下の断熱ボード7は密着することにより止水されるが、水切板19に取付けた横目地用二次止水材21によって、より確実に止水が行われるようになること、縦目地3を形成する外壁パネル2においても、左右両側の断熱ボード7が密着するため止水機能を果たし、縦目地ガスケット11と相俟って縦目地の止水が行われること、縦目地3と横目地4が十文字に交差する箇所では、水切板19が胴縁6に跨って縦目地3を横断し、しかも止水板19の垂直部19bが縦目地ガスケット11のスリット16に挿入され、これによりスリット16より下方の水切板19の垂直部19bが届かない止水構造と同様、胴縁間を塞ぐシールリップ15でシール構造を屋内側に残された立ち上がり片17で維持させながら止水板19を設置することができる。また止水板19の垂直部19bの挿入により立ち上がり片17が位置規制されてシールリップ15が両側の胴縁6に確実に押付けられるようにすることもでき、止水が行われるようになること、屋内外に垂下片25、26を設けた横目時ガスケット24が階下の外壁パネル2における外壁面材5の小口面に被さって取付けられるが、この取付時には垂下片25、26が位置決め機能を果たし、所定位置への取付けが容易かつ確実に行われ、また前記垂下片25、26により、該小口面からの水の浸入を防ぐことができること、横目地ガスケット24が縦目地3を横断して横目地4に装填されるようになり、横目地ガスケット24が一本で連なっているため意匠性に優れること、等の効果を有する。 According to the joint structure of the present embodiment, the horizontal joint 4 is stopped by the horizontal joint gasket 24 which is the primary waterproofing material for the horizontal joint and the draining plate 19, and the double draining water is stopped. 19 is supported by the horizontal portion 19a being sandwiched between the heat insulating boards 7 of the upper and lower outer wall panels 2, and in order to support the draining plate 19, the draining plate 19 and the outer wall panel 2 have a special structure or are provided with an attachment device. There is no need, and the number of man-hours for installation is not increased, construction is easy, and the upper and lower heat insulation boards 7 are stopped by close contact, but the secondary joint for the horizontal joint attached to the draining plate 19 is stopped. The water material 21 ensures water stoppage more reliably, and the outer wall panel 2 that forms the vertical joint 3 also has a water stop function because the heat insulating boards 7 on both the left and right sides are in close contact with each other. Together with the vertical In the place where the water stop of the ground is performed and the vertical joint 3 and the horizontal joint 4 intersect with the cross, the draining plate 19 straddles the vertical joint 3 across the trunk edge 6, and the vertical portion 19 b of the water stop plate 19. Is inserted into the slit 16 of the vertical joint gasket 11, so that the vertical structure 19 b below the slit 16 does not reach the vertical portion 19 b of the water drainage plate 19. The water stop plate 19 can be installed while being maintained by the remaining rising pieces 17. Further, the position of the rising piece 17 can be regulated by the insertion of the vertical portion 19b of the water stop plate 19, and the seal lip 15 can be surely pressed against the body edges 6 on both sides, so that the water stop is performed. The horizontal gasket 24 provided with hanging pieces 25 and 26 indoors and outdoors is attached so as to cover the small surface of the outer wall surface material 5 in the outer wall panel 2 of the downstairs. It is possible to easily and surely attach to a predetermined position, and the drooping pieces 25 and 26 can prevent water from entering from the facet, and the horizontal joint gasket 24 crosses the vertical joint 3 to Since it comes to be loaded into the ground 4 and the horizontal joint gaskets 24 are connected in a single line, it has an effect such as excellent design.
