Description

本発明は、上下の方立と左右の無目とを突き合わせる連結部を有するカーテンウォールに関する。   The present invention relates to a curtain wall having a connecting portion that abuts upper and lower vertical surfaces and left and right invisible eyes.

従来、カーテンウォールの方立と無目との連結部は、湿式のシール材でシールして防水していた。しかし、湿式のシール材は、シール材により外壁が汚れること、劣化しやすいこと、養生期間が必要でありまた雨天時には施工ができず作業性が悪いこと、シール目地がポケット状になり水がたまりやすいことなどが問題であった。そこで、特許文献1のカーテンウォールは、湿式のシール材を用いず、方立と無目のそれぞれの端部にシリコンスポンジゴムを配してあり、左右の無目に配したシリコンスポンジゴム同士が当接し、さらにその上下に方立に配したシリコンスポンジゴムが当接することで防水している(図10)。こうした防水用のゴムは成形品であるから管理がしやすく、シール材のように外壁を汚すこともない。また、耐久性、作業性も良好である。   Conventionally, the connecting portion of the curtain wall in the vertical direction and the invisible state has been waterproofed by sealing with a wet sealant. However, the wet seal material is contaminated by the seal material, easily deteriorates, requires a curing period, cannot be constructed in rainy weather, and has poor workability. The problem was that it was easy. Therefore, the curtain wall of Patent Document 1 does not use a wet sealing material, and silicon sponge rubber is arranged at each end of the vertical and invisible, and the left and right invisible silicone sponge rubbers are connected to each other. It is waterproofed by contact with silicon sponge rubber arranged vertically on the top and bottom (FIG. 10). Since such waterproof rubber is a molded product, it is easy to manage, and the outer wall is not soiled like a sealing material. Also, durability and workability are good.

続いて、連結部Jの詳細について、組み立て後及び組み立て途中の斜視図である図1〜図4に基づいて説明する。ただし、これらの図において、タイト材及びガラスパネルについては省略した。この連結部Jにおいて、上側の方立1の下端小口からは室内側面が下方に延出して、延出壁部11を形成している。延出壁部11の室外側には、略平板形状の上方立防水ブロック6を接着して設けてある。一方、下側の方立2の上端小口には、略コ字形状の下方立防水ブロック7が、前側に開口する向きに設けてある。下方立防水ブロック7は、左右方向中央で二分割されており、下面には突出部(図示省略)を備え、この突出部を方立2の中空部22に差し込んである。そしてコ字形状の中央の欠損部分を上下に貫通する排水部72とし、排水部72は中空部22と連通している。さらに、左右の無目3の対向する小口には、それぞれ無目防水ブロック8が設けてある。無目防水ブロック8の形状は、図8(a)に示すものであり、前後方向に延びる胴部85と、胴部85の他方の無目3と対向する側に形成した見込面81と、胴部85の室内側に形成した室内側面82と、胴部85の室外側に形成した室外側面86と、室外側面86の下端の下面84と、胴部85の下側に形成したリブ87とを有し、胴部85とリブ87の間に溝部88が形成されている。また、胴部85の上面83は、見込面81側に向けて上向きに傾斜しており、見込面81の下端面89は、見込面81側に向けて下向きに傾斜している。このように形成した無目防水ブロック8は、図8(b)に示すように、無目3の補強材32及び延出部33を溝部88に挿入して無目3の小口に取り付けてある。この際、上面83は、見込面81側から、無目3の見込面である補強材32及び延出部33に向けて下り勾配で傾斜し、室内側面82は無目3の室内側面31と面一になり、室外側面86は無目3の延出部33の室外側面35と略面一になる。また、連結部J近傍において、無目3の室外側面には排水窓37を形成してあり、延出部33には室外側面35及び係合部36の一部を切り欠いた切欠部38が形成してある。さらに、無目3の押縁10には、室内側面と見込面のそれぞれに排水孔10a,10bが形成してある。また、下側の方立2に設けた押縁5の上端小口には、押縁防水ブロック9が設けてある。押縁防水ブロック9は、縦断面が台形で、下面には突出部(図示省略)を備え、この突出部を押縁5の上端に差し込んである。なお、各防水ブロックは、シリコンスポンジゴムからなる。   Then, the detail of the connection part J is demonstrated based on FIGS. 1-4 which are perspective views after an assembly and in the middle of an assembly. However, in these figures, the tight material and the glass panel are omitted. In this connecting portion J, the interior side surface extends downward from the lower end edge of the upper stand 1 to form an extended wall portion 11. On the outdoor side of the extending wall portion 11, a substantially flat upper waterproof block 6 is bonded and provided. On the other hand, an approximately U-shaped lower vertical waterproof block 7 is provided at the upper end edge of the lower stand 2 so as to open to the front side. The lower vertical waterproof block 7 is divided into two at the center in the left-right direction, and has a protruding portion (not shown) on the lower surface, and this protruding portion is inserted into the hollow portion 22 of the vertical 2. Then, the U-shaped central missing portion is used as a drainage portion 72 penetrating vertically, and the drainage portion 72 communicates with the hollow portion 22. Furthermore, the waterproof waterproof block 8 is provided in the opposite small opening of the left and right seamless 3 respectively. The shape of the seamless waterproof block 8 is as shown in FIG. 8A, and includes a trunk portion 85 extending in the front-rear direction, a prospective surface 81 formed on the side of the trunk portion 85 facing the other invisible 3, An indoor side surface 82 formed on the indoor side of the trunk portion 85, an outdoor side surface 86 formed on the outdoor side of the trunk portion 85, a lower surface 84 at the lower end of the outdoor side surface 86, and a rib 87 formed on the lower side of the trunk portion 85. A groove portion 88 is formed between the body portion 85 and the rib 87. Further, the upper surface 83 of the trunk portion 85 is inclined upward toward the expected surface 81 side, and the lower end surface 89 of the expected surface 81 is inclined downward toward the expected surface 81 side. As shown in FIG. 8B, the seamless waterproof block 8 formed in this way is attached to the small edge of the seamless 3 by inserting the reinforcing member 32 and the extending portion 33 of the seamless 3 into the groove 88. . At this time, the upper surface 83 is inclined downwardly from the prospective surface 81 side toward the reinforcing member 32 and the extending portion 33 that are the prospective surfaces of the seamless 3, and the indoor side surface 82 is connected to the indoor side surface 31 of the seamless 3. The outdoor side surface 86 is substantially flush with the outdoor side surface 35 of the extension portion 33 of the mesh 3. Further, in the vicinity of the connecting portion J, a drainage window 37 is formed on the seamless outdoor side surface, and the extended portion 33 has a cutout portion 38 in which a part of the outdoor side surface 35 and the engaging portion 36 are cut out. It is formed. Furthermore, drain holes 10a and 10b are formed in the seamless ledge 10 on the indoor side surface and the prospective surface, respectively. Further, a ledge waterproof block 9 is provided at the upper end edge of the ledge 5 provided on the lower side wall 2. The pressed-edge waterproof block 9 has a trapezoidal vertical cross section, and has a protruding portion (not shown) on the lower surface. The protruding portion is inserted into the upper end of the pressed edge 5. Each waterproof block is made of silicon sponge rubber.

そして、これらの方立1,2及び無目3を、ブラケット100により連結する。ブラケット100は十字形で、上下左右に延びる腕部101を有している。まず、下側の方立2を、ブラケット100の下側の腕部101にネジ止めする(図2の状態)。続いて、上側の方立1を、ブラケット100の上側の腕部101にネジ止めする(図3の状態)。この際、上方立防水ブロック6の下面62が、下方立防水ブロック7の上面71に圧接する。そしてこの状態では、上側の方立1、その延出壁部11及び下側の方立2が左右方向から見て略コ字形になっており、その開口部に左右の無目3が嵌るように、それぞれブラケット100の左右の腕部101にネジ止めする(図1の状態)。この際、両無目防水ブロック8の見込面81が互いに圧接し、また上方立防水ブロック6の室外側面61が無目防水ブロック8の室内側面82及び無目3の室内側面31に圧接する。また、下側の方立2の取付溝23に押縁5を取り付け、押縁5の押縁防水ブロック9の上面91が無目防水ブロック8の下面84に圧接する。さらに、上側の方立1の取付溝13及び左右の無目3の延出部33にそれぞれ押縁4,10を取り付け、上側の押縁4の下端が押縁防水ブロック9に圧接し、上下の押縁4,5及び左右の押縁10は面一となる。なお、上側の方立1の下端と左右の無目3との間及び上側の押縁4と左右の押縁10との間はシール材Sによりシールしてある(図4の状態)。   Then, these verticals 1 and 2 and the seamless 3 are connected by the bracket 100. The bracket 100 has a cross shape, and has an arm portion 101 extending vertically and horizontally. First, the lower stand 2 is screwed to the lower arm 101 of the bracket 100 (state shown in FIG. 2). Subsequently, the upper stand 1 is screwed to the upper arm 101 of the bracket 100 (state shown in FIG. 3). At this time, the lower surface 62 of the upper standing waterproof block 6 is in pressure contact with the upper surface 71 of the lower standing waterproof block 7. In this state, the upper stand 1, its extending wall portion 11 and the lower stand 2 are substantially U-shaped when viewed from the left-right direction, and the left and right invisible eyes 3 fit into the opening. Next, the left and right arms 101 of the bracket 100 are screwed to each other (state shown in FIG. 1). At this time, the prospective surfaces 81 of both the seamless waterproof blocks 8 are in pressure contact with each other, and the outdoor side surface 61 of the upper standing waterproof block 6 is in pressure contact with the indoor side surface 82 of the seamless waterproof block 8 and the indoor side surface 31 of the seamless 3. Further, the pressing edge 5 is attached to the mounting groove 23 of the lower vertical 2, and the upper surface 91 of the pressing edge waterproof block 9 of the pressing edge 5 is pressed against the lower surface 84 of the seamless waterproof block 8. Further, the pressing edges 4 and 10 are respectively attached to the mounting groove 13 of the upper stand 1 and the left and right extension parts 33, and the lower ends of the upper pressing edges 4 are in pressure contact with the pressing edge waterproof block 9, so that the upper and lower pressing edges 4 , 5 and the left and right pushing edges 10 are flush with each other. In addition, the space between the lower end of the upper stand 1 and the left and right blanks 3 and the space between the upper pressing edge 4 and the left and right pressing edges 10 are sealed with a sealing material S (state shown in FIG. 4).

このように構成したカーテンウォールの連結部Jにおいては、上側の方立1の延出壁部11に設けた上方立防水ブロック6が無目3の室内側面31に対向しており、無目防水ブロック8の室内側面82が上方立防水ブロック6の室外側面61に圧接していることから、水が上方立防水ブロック6より室内側に浸入するのを確実に防ぐことができる。また、無目3の室内側面31が上方立防水ブロック6の室外側面61に圧接していることから、方立1,2に対する無目3の水平方向の角度変位の許容範囲が拡大し、多少のズレが有る場合でも防水性を確保できる。さらに、無目防水ブロック8の胴部85の上面83が傾斜しているので、図1中の一点鎖線で示すように、水が連結部Jから左右の無目3の補強材32又は延出部33に導かれる。補強材32に導かれた水は、補強材32が室外側に向けて下向きに傾斜しているから、排水窓37を通って延出部33へ流れる。そして延出部33に導かれた水は、切欠部38又は押縁10の排水孔10a,10bを通って室外側に排水される。さらに、互いに圧接する見込面81に水が浸透した場合でも、その水は下方立防水ブロック7の排水部72から下側の方立2の中空部22へと導かれ、当該連結部Jの一段下の連結部に到達し、無目防水ブロックにより左右方向に導かれる。また、下側の押縁5に設けた押縁防水ブロック9の上面91が無目防水ブロック8の下面84に圧接しているので、押縁5の上端部からの水の浸入を防ぐことができる。そして上側の押縁4の下端が押縁防水ブロック9に圧接しているから、上下の押縁4,5の間にシール材を用いる必要がなく、また上側の押縁4により無目防水ブロック8及び押縁防水ブロック9が覆い隠され、さらに上下の押縁4,5と左右の押縁10とが面一となるから、外観が良好である。そしてこのように押縁4,5,10を設けることで、室外側から浸入する水に対して、まず押縁4,5,10が防水機能を発揮し、そこから浸入したとしても、さらにその室内側の無目防水ブロック8、上方立防水ブロック6及び下方立防水ブロック7が防水機能を発揮する二重の防水構造となるので、防水性が非常に高い。さらに、十字形のブラケット100のそれぞれの腕部101に上下の方立1,2及び左右の無目3を連結すればよいので、連結部Jにおける方立1,2及び無目3の位置決めが容易である。   In the connecting portion J of the curtain wall configured as described above, the upper vertical waterproof block 6 provided on the extended wall portion 11 of the upper side wall 1 is opposed to the seamless indoor side surface 31, so Since the indoor side surface 82 of the block 8 is in pressure contact with the outdoor side surface 61 of the upper standing waterproof block 6, it is possible to reliably prevent water from entering the indoor side from the upper standing waterproof block 6. In addition, since the interior side surface 31 of the seamless 3 is in pressure contact with the outdoor surface 61 of the upper standing waterproof block 6, the allowable range of the horizontal angular displacement of the seamless 3 with respect to the verticals 1 and 2 is increased. Waterproofness can be ensured even when there is a gap. Furthermore, since the upper surface 83 of the trunk portion 85 of the seamless waterproof block 8 is inclined, the water extends from the connecting portion J to the left and right reinforcing members 32 or extends from the connecting portion J, as shown by the one-dot chain line in FIG. Guided to section 33. The water guided to the reinforcing material 32 flows to the extending portion 33 through the drainage window 37 because the reinforcing material 32 is inclined downward toward the outdoor side. And the water guide | induced to the extension part 33 is drained to the outdoor side through the notch part 38 or the drain holes 10a and 10b of the pressing edge 10. FIG. Further, even when water permeates the prospective surfaces 81 that are in pressure contact with each other, the water is guided from the drainage portion 72 of the lower vertical waterproofing block 7 to the hollow portion 22 of the lower vertical 2, and one level of the connecting portion J. It reaches the lower connecting part and is guided in the left-right direction by the seamless waterproof block. In addition, since the upper surface 91 of the ledge waterproof block 9 provided on the lower ledge 5 is in pressure contact with the lower surface 84 of the seamless waterproof block 8, it is possible to prevent water from entering from the upper end of the ledge 5. Since the lower end of the upper pressing edge 4 is in pressure contact with the pressing edge waterproof block 9, it is not necessary to use a sealing material between the upper and lower pressing edges 4, 5. Since the block 9 is covered and the upper and lower pressing edges 4 and 5 and the left and right pressing edges 10 are flush with each other, the appearance is good. And by providing the pressing edges 4, 5, 10 in this way, the pressing edges 4, 5, 10 first exert a waterproof function against the water entering from the outdoor side, and even if it enters from there, the indoor side Since the invisible waterproof block 8, the upper standing waterproof block 6 and the lower standing waterproof block 7 have a double waterproof structure that exhibits a waterproof function, the waterproof property is very high. Furthermore, since the vertical vertices 1 and 2 and the left and right invisible 3 need only be connected to the respective arm portions 101 of the cross-shaped bracket 100, the positioning of the vertical 1, 2 and the invisible 3 in the connecting portion J can be performed. Easy.

また、図9に示すように、方立及び無目に嵌め込まれたガラスパネルPが層間変位した場合でも、無目防水ブロック8の上面83及び下端面89が傾斜しているから、ガラスパネルPと無目防水ブロック8との衝突を回避できる。   Further, as shown in FIG. 9, even when the glass panel P fitted in a vertical or invisible state is displaced between layers, the upper surface 83 and the lower end surface 89 of the invisible waterproof block 8 are inclined, so that the glass panel P Can be avoided.

本発明は、上記の実施形態に限定されない。各防水ブロックの形状は、上記の作用効果を奏するものであれば、方立や無目の形状等に合わせて適宜変更できる。また、各防水ブロックの素材は、他の部材と圧接して水の浸入を防ぐことができるものであればどのようなものでもよい。   The present invention is not limited to the above embodiment. The shape of each waterproof block can be appropriately changed according to the vertical or invisible shape as long as the above-described effects are exhibited. In addition, the material of each waterproof block may be any material that can be pressed against other members to prevent water from entering.
