【考案の詳細な説明】 この考案は外壁構造に関するもので、施工が容易でかつ
防水寿命が長く、信頼性のすぐれた外壁構造を提供する
ことを目的とする。[Detailed description of the invention] This invention relates to an exterior wall structure, and aims to provide an exterior wall structure that is easy to construct, has a long waterproof life, and is highly reliable.

この考案の一実施例を第１図ないし第３図に基づいて説
明する。An embodiment of this invention will be explained based on FIGS. 1 to 3.

すなわち、この外壁構造は、第１図および第２図に示す
ように、上部１を偏平板状に形威し下部２を外側下方に
Ｚ形に屈曲して垂下させるとともにその下端３を内側上
方に屈曲させた水切片４の前記上部１を、２階の外壁パ
ネル５の外装材６とその下枠材７とで挾持させている。That is, as shown in FIGS. 1 and 2, this outer wall structure has an upper part 1 shaped like a flat plate, a lower part 2 bent outward and downward in a Z-shape, and a lower end 3 of the upper part 1 extending inward and upward. The above-mentioned upper part 1 of the water section 4, which is bent in the following manner, is held between the exterior material 6 of the second floor exterior wall panel 5 and its lower frame material 7.

また、この外壁パネル５は、下枠材７の下端面よりも後
退させた位置に外装材６を貼着しているため、その下枠
材７は外装材６の下端面より下方に突出形成された構造
となっており、その結果、水切片４の下部２すなわち外
側下方に屈曲させた部分と下枠材７との間に縦の幕板差
込空間１９が生じている。In addition, since the exterior wall panel 5 has the exterior material 6 attached at a position set back from the lower end surface of the lower frame material 7, the lower frame material 7 is formed to protrude downward from the lower end surface of the exterior material 6. As a result, a vertical curtain insertion space 19 is created between the lower part 2 of the water section 4, that is, the part bent outward and downward, and the lower frame member 7.

そして、この差込空間１９には防水性のコーキング材８
を充填するとともに、上端９を外側下方に屈曲させ下端
１０を内側上方に屈曲させた幕板１１の上端９を下から
そのコーキング材８の中に圧入しており、さらに、その
幕板１１の下部１２を１階の壁パネル１３の外装材１４
に合板１５と粘着性の防水用ゴムアスファルトシート１
６とを介して釘１７で固定している。A waterproof caulking material 8 is provided in this insertion space 19.
At the same time, the upper end 9 of the curtain plate 11 with the upper end 9 bent outward and downward and the lower end 10 bent inward and upward is pressed into the caulking material 8 from below. The lower part 12 is the exterior material 14 of the wall panel 13 on the first floor.
15 plywood and 1 adhesive waterproof rubber asphalt sheet
6 and fixed with nails 17.

なお、１階および２階の外壁パネル５，１３は梁１８を
介して結合されている。Note that the outer wall panels 5 and 13 on the first and second floors are connected via beams 18.

また、この実施例においては、水切片４および幕板１１
はいずれも亜鉛めっき鋼板を折曲して形成したものであ
り、外装材６および１４とともに同色の塗装仕上げをし
ている。In addition, in this embodiment, the water section 4 and the curtain plate 11
Both are formed by bending galvanized steel plates, and are painted in the same color as the exterior materials 6 and 14.

また、水切片４は工場における外壁パネル５の組立時に
その外壁パネル５に組込むもので、エポキシ系接着剤等
により下枠材７および外装材６と強力に接着しており、
構造耐力上の力の伝達はスムーズに行われる。In addition, the water section 4 is assembled into the outer wall panel 5 when the outer wall panel 5 is assembled in the factory, and is strongly bonded to the lower frame material 7 and the exterior material 6 using epoxy adhesive or the like.
Smooth transmission of structural strength forces.

このように構成したため、この幕板１１の施工に際して
は、１階および２階の外壁パネル１３，５を建て込み後
、２階の外壁パネル５の下枠材７と水切片４の間の差込
空間１９にコーキング材８を充填し、その下方から幕板
１１の上端９を挿入するとともに下部１２を釘１７で１
階の外壁パネル１３に固定するだけで第３図のように簡
単に取付けることができる。Because of this structure, when constructing this curtain board 11, after installing the first and second floor exterior wall panels 13 and 5, the difference between the lower frame material 7 and the water section 4 of the second floor exterior wall panel 5 must be adjusted. Fill the caulking space 19 with caulking material 8, insert the upper end 9 of the curtain plate 11 from below, and secure the lower part 12 with nails 17.
It can be easily installed by simply fixing it to the outer wall panel 13 of the floor as shown in FIG.

また、コーキング材８およびゴムアスファルトシート１
６により、雨水が、幕板１１と水切片４問および幕板１
１と外壁パネル１３間を通って壁内へ侵入するのを防止
できる。In addition, caulking material 8 and rubber asphalt sheet 1
According to 6, rainwater is divided into curtain board 11, water section 4 questions, and curtain board 1.
1 and the outer wall panel 13 and can be prevented from entering the wall.

しかも、コーキング材８は水切片４の内側に充填するこ
ととなるため、太陽光線や外気に直接さらされることが
なく、シたがって劣化することが少なく耐久性が向上す
る。Moreover, since the caulking material 8 is filled inside the water segment 4, it is not directly exposed to sunlight or the outside air, and therefore, it is less likely to deteriorate and has improved durability.

また、下部１２の釘１７により固定部分はゴムアスファ
ルトシート１６を内側に入れたため、釘穴から雨水など
が浸込むこともなく、コーキングを省略できる。Further, since the rubber asphalt sheet 16 is placed inside the part fixed by the nails 17 of the lower part 12, rainwater etc. will not seep through the nail holes, and caulking can be omitted.

また、このゴムアスファルトシート１６も、幕板１１の
裏面側に配設されて屋外側へ露出しないため、劣化速度
を低減できて防水寿命を伸ばせる。Moreover, since this rubber asphalt sheet 16 is also disposed on the back side of the curtain plate 11 and is not exposed to the outside, the rate of deterioration can be reduced and the waterproof life can be extended.

さらに、この水切片４は幕板１１は、工場で生産できる
ため品質の安定した信頼性の高いものとなり、現場での
手直しなどの作業ロスがなくなって施工能率を高めるこ
とができる。Furthermore, since the water strips 4 and the curtain plates 11 can be produced in a factory, they are of stable quality and highly reliable, and work losses such as on-site rework are eliminated, making it possible to improve construction efficiency.

また、水切片４と幕板１１とを外装材６および１４と同
色に仕上げているため接続部が目立たず外観がすぐれた
ものとなる。Further, since the water strip 4 and the curtain plate 11 are finished in the same color as the exterior materials 6 and 14, the connecting portions are not noticeable and the appearance is excellent.

さらにまた、幕板１１の下端１０を内側上方に屈曲させ
ているため、この下端１０が水切片の機能を果たし、し
たがって幕板１１の下方に別途水切板を付設する必要も
なくなる。Furthermore, since the lower end 10 of the curtain plate 11 is bent inwardly and upwardly, this lower end 10 functions as a water cutter, and therefore there is no need to separately attach a water cutter plate below the curtain plate 11.

その上、水切片４の下端３を内側上方に屈曲させるとと
もに、幕板１１の上端９を外側下方に屈曲させたため、
幕板１１の下部を下階外壁パネル１３へ固定する際に、
誤って幕板１１を下方へずらせても、水切片４の下端３
が幕板１１の上端９を係止して幕板差込空間１９から抜
は出るのを防止できる。Moreover, since the lower end 3 of the water section 4 is bent inward and upward, and the upper end 9 of the curtain plate 11 is bent outward and downward,
When fixing the lower part of the curtain board 11 to the lower floor exterior wall panel 13,
Even if you accidentally shift the curtain plate 11 downward, the lower end 3 of the water section 4
can lock the upper end 9 of the curtain plate 11 and prevent it from coming out from the curtain plate insertion space 19.

以上のように、この外壁構造によれば、施工が容易で、
かつ防水寿命が長く、信頼性にも優れるという効果が得
られる。As described above, this exterior wall structure is easy to construct,
Moreover, the effect of having a long waterproof life and excellent reliability can be obtained.
