Description

本発明は、カーテンウォールに係わり、特にパネルの下辺を押さえる押縁の構造に関する。   The present invention relates to a curtain wall, and more particularly, to a structure of a pressing edge for pressing a lower side of a panel.

建物の外壁に取付けられるパネルとして、パネルの下辺を押さえる押縁を室外側から装着するものがある（例えば特許文献１参照）。この特許文献１に記載の押縁は、押縁の上端に室内側に下向きに曲成されて形成された鈎状の係止片を横枠の室外側の上方への突片に係止し、押縁の下部に室内側に突出して設けた係止片を横枠に設けた係止部に嵌合して固定する構造を有している。   As a panel attached to the outer wall of a building, there is one in which a pressing edge that holds the lower side of the panel is mounted from the outdoor side (see, for example, Patent Document 1). The pressing edge described in Patent Document 1 locks a hook-shaped locking piece formed by bending downward on the indoor side at the upper end of the pressing edge to a protruding piece on the outside of the outdoor side of the horizontal frame. It has a structure in which a locking piece that protrudes toward the indoor side is fitted and fixed to a locking portion provided in the horizontal frame.

特開２０００−２６５６０７号公報JP 2000-265607 A

カーテンウォールにおいては、美観の向上のため、パネルを保持する枠や押縁の外観上の幅の縮小が求められているが、前記特許文献１に記載のような上下の係止構造を採用するには、アルミニウム合金製押出形材でなる押縁にはある程度の上下幅を必要とするので、上下幅の縮小が困難である。また、押縁を取付ける作業において、横枠に仮止めした状態で押縁が落下すると危険であり、また、落下により押縁が破損するおそれがあるので、仮止め状態での押縁の落下を防止しなければならない。   In the curtain wall, in order to improve the aesthetic appearance, the frame holding the panel and the width of the press rim are required to be reduced in width, but the upper and lower locking structure as described in Patent Document 1 is employed. However, it is difficult to reduce the vertical width because the pressing edge made of an aluminum alloy extruded shape requires a certain vertical width. In addition, in the work of attaching the ledge, it is dangerous if the ledge falls while it is temporarily fixed to the horizontal frame, and the ledge may be damaged by dropping, so it is necessary to prevent the ledge from falling in the temporarily fixed state. Don't be.

本発明は、上記事情に鑑みてなされたもので、上下幅の縮小が可能であって、しかも仮止め状態での落下が確実に防止できる押縁を有するカーテンウォールを提供することを目的とする。   The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a curtain wall having a pressing edge that can be reduced in vertical width and that can be reliably prevented from falling in a temporarily fixed state.

請求項１のカーテンウォールは、パネルを左右の縦枠および上下の横枠または無目により囲み、パネルの下側を受ける横枠または無目の室外側に、室外側が開口された空洞部を形成し、
前記空洞部は、その底部内面の室外側に上方に突出した係止受部を有し、
パネルの下辺を室外側から押さえる押縁に、前記空洞部への嵌入部を室内側に突出させ、かつ先端が斜め上向きとなるように曲げた形に形成し、
前記嵌入部の下面に下方に突出した係止突起を設け、
前記押縁が斜めとなり前記嵌入部が前記空洞部へ嵌入された仮止め状態において前記係止突起が前記係止受部に係止されて押縁が外れ止めされる
ことを特徴とする。 The curtain wall of claim 1 surrounds a panel with left and right vertical frames and upper and lower horizontal frames or a mesh, and has a hollow portion that is open to the outside of a horizontal frame or a seamless outdoor space that receives the lower side of the panel. Forming,
The hollow portion has a locking receiving portion protruding upward on the outdoor side of the inner surface of the bottom portion,
To the pressing edge that holds the lower side of the panel from the outdoor side, the insertion part into the hollow part protrudes to the indoor side, and is formed in a shape bent so that the tip is obliquely upward,
A locking projection protruding downward is provided on the lower surface of the fitting portion,
In the temporarily fixed state in which the pressing edge is inclined and the insertion portion is inserted into the hollow portion, the locking protrusion is locked to the locking receiving portion and the pressing edge is prevented from coming off.

本発明においては、横枠または無目の空洞部の底部内面に係止受部を設け、その係止受部に押縁の嵌入部の下面に設けた係止突起を係止させることにより、押縁の仮止め状態における押縁の外れ止めがなされるので、押縁の仮止め状態における押縁の落下が防止される。また、この空洞部内で押縁を外れ止めする構造によれば、横枠の外側に押縁の係止部を設けて押縁をその係止部に係止させる場合に比較して、押縁の上下幅を狭幅に形成でき、外観向上に寄与することができる。   In the present invention, a latch receiving portion is provided on the inner surface of the bottom of the horizontal frame or the invisible hollow portion, and the latch receiving projection is provided on the lower surface of the fitting portion of the press rim. Since the ledge is prevented from coming off in the temporarily fixed state, the falling edge of the ledge in the temporarily fixed state of the ledge is prevented. Further, according to the structure in which the pressing edge is prevented from coming off in the hollow portion, the vertical width of the pressing edge can be increased as compared with the case where the locking portion of the pressing edge is provided outside the horizontal frame and the pressing edge is locked to the locking portion. It can be formed with a narrow width and can contribute to an improvement in appearance.

図３はこの実施の形態におけるパネル１の取付け構造を示す縦断面図である。この実施の形態においては、１部が前記開閉可能な障子１１である場合について示すが、このような開閉式障子１１でない嵌め殺し式構造が連続する部分にも適用できる。３Ａ、３Ｂは方立に固定された無目であり、３Ａは嵌め殺し状にパネル１Ａの下辺を押縁１２と共に保持するものである。３Ｂは嵌め殺し状にパネル１Ｂの上辺を保持するものである。   FIG. 3 is a longitudinal sectional view showing the mounting structure of the panel 1 in this embodiment. In this embodiment, although the case where one part is the openable / closable shoji 11 is shown, the present invention can also be applied to a portion in which such an open / close type shoji 11 is continuous. 3A and 3B are seamlessly fixed in the vertical direction, and 3A holds the lower side of the panel 1A together with the pressing edge 12 in a fitting manner. 3B retains the upper side of the panel 1B in a fitting manner.

障子１１は左右の縦枠１３と上下の横枠１４とでパネル１Ｃを備えるもので、本実施の形態においては、上下のリンク機構１５、１６により無目３Ａ、３Ｂに開閉可能に取付けられた縦辷り出し窓を構成している。１７はパネル１Ｃの下辺を押さえる押縁である。２５は無目３A、横枠１４の底部に設けた水抜き穴である。   The shoji 11 is provided with a panel 1C with left and right vertical frames 13 and upper and lower horizontal frames 14, and in the present embodiment, the shoji 11 is attached to the invisible eyes 3A and 3B by the upper and lower link mechanisms 15 and 16. It constitutes a vertical window. Reference numeral 17 denotes a pressing edge for pressing the lower side of the panel 1C. A drain hole 25 is provided at the bottom of the seamless frame 3A and the horizontal frame 14.

図４は前記押縁１２の無目３Ａに対する取付け構造を示す図である。パネル１Ａは無目３Ａ上にセッティングブロック１９を介して設置される。無目３Ａの室外側には室外側に開口部２０を有する空洞部２１を形成する。この空洞部２１は室内側に断面形状が弧状の内面２１ａを有する。また、底部内面２１ｂの室外側には、上方に突出した係止受部２１ｃを形成する。この係止受部２１ｃは好ましくは上部が室内側に向かうように傾斜した断面形状とする。また、開口部２０の上部には、斜め下方に向けて形成された係止片２１ｄを有する。   FIG. 4 is a view showing an attachment structure of the pressing edge 12 to the seamless 3A. The panel 1A is installed on the seamless 3A via a setting block 19. A hollow portion 21 having an opening 20 on the outdoor side is formed on the outdoor side of the seamless 3A. The hollow portion 21 has an inner surface 21a having an arcuate cross section on the indoor side. A locking receiving portion 21c protruding upward is formed on the outdoor side of the bottom inner surface 21b. The locking receiving portion 21c preferably has a cross-sectional shape that is inclined so that the upper portion faces the indoor side. Moreover, the upper part of the opening part 20 has the locking piece 21d formed toward diagonally downward.

一方、パネル１Ａの下辺を押さえる押縁１２の室内側の面に、前記空洞部２１への嵌入部２２を室内側に突出させて形成する。この嵌入部２２は、断面形状が水平部２２ａと斜め上向きに曲成された傾斜部２２ｂを有する曲成形状に形成するか、あるいは先端が斜め上向きとなるように全体に曲成された形状に形成する。また、この嵌入部２２の先端２２ｃは断面形状が円弧状をなすように形成することが嵌入を円滑化する意味で好ましい。また、嵌入部２２の下面に下方に突出した係止突起２２ｄを設ける。   On the other hand, a fitting portion 22 into the hollow portion 21 is formed on the indoor side surface of the pressing edge 12 that holds the lower side of the panel 1A so as to protrude to the indoor side. The insertion portion 22 is formed in a curved shape having an inclined portion 22b whose cross-sectional shape is bent obliquely upward with the horizontal portion 22a, or in a shape bent entirely so that the tip is inclined upward. Form. In addition, it is preferable that the tip 22c of the insertion portion 22 is formed so that the cross-sectional shape is an arc shape in order to facilitate the insertion. Further, a locking projection 22d protruding downward is provided on the lower surface of the fitting portion 22.

図５は無目３Ａ上にセッティングブロック１９を介してパネル１Ａをセットした後、室外側から嵌入部２２を空洞部２１内に開口部２０から嵌入して押縁１２を仮止した状態を示す。この仮止めに際して、嵌入部２２を空洞部２１に挿入する際には、嵌入部２２の先端２２ｃが弧状をなし、その先端２２ｃが空洞部２１の室内側の弧状をなす内面２１ａに沿って摺動するので、空洞部２１に嵌入部２２が円滑に挿入される。   FIG. 5 shows a state in which the panel 1A is set on the seamless 3A via the setting block 19, and then the insertion portion 22 is inserted into the hollow portion 21 from the opening portion 20 from the outdoor side and the pressing edge 12 is temporarily fixed. When the fitting portion 22 is inserted into the cavity portion 21 during the temporary fixing, the tip 22c of the fitting portion 22 forms an arc shape, and the tip 22c slides along the inner surface 21a that forms an arc shape on the indoor side of the cavity portion 21. Therefore, the fitting portion 22 is smoothly inserted into the cavity portion 21.

この押縁１２の仮止め状態においては、押縁１２は上部が室内側に傾いた傾斜姿勢となる。このとき、押縁１２の係止突起２２ｄは空洞部２１の底面の係止受部２１ｃに係止され、押縁１２が空洞部２１から外れ止めされる。従って、押縁１２が仮止め状態で外れて落下する心配がないので、作業者はこの押縁１２を放置して次の作業を任意に選択することができる。なお、前記仮止め状態において、係止突起２２ｄの室外側の面は、図５に示すように、係止受部２１ｃの室内側の傾斜面に合致する傾斜面となるように形成されていることが、押縁１２の振動による浮きを防止し外れを防止する上で好ましい。   In the temporarily fixed state of the ledge 12, the ledge 12 is in an inclined posture with the upper portion inclined toward the indoor side. At this time, the locking protrusion 22 d of the pressing edge 12 is locked to the locking receiving portion 21 c on the bottom surface of the cavity portion 21, and the pressing edge 12 is prevented from coming off from the cavity portion 21. Therefore, since there is no fear that the pressing edge 12 comes off in the temporarily fixed state and falls, the operator can leave the pressing edge 12 and arbitrarily select the next work. In the temporarily fixed state, the outer surface of the locking projection 22d is formed to be an inclined surface that matches the inclined surface on the indoor side of the locking receiving portion 21c, as shown in FIG. This is preferable in order to prevent the lip 12 from being lifted by vibrations and preventing it from coming off.

続いて図４に示すようにパネル１Ａと押縁１２の上部との間に乾式または湿式のシール材２３を嵌め込む。このシール材２３の施工により、シール材２３の圧力で押縁１２の上部が室外側が外方に押され、嵌入部２２が空洞部２１の係止片２１ｄに当接し、押縁１２の下部２４が無目３Ａの室外側の面に当接した垂直姿勢となる。   Subsequently, as shown in FIG. 4, a dry or wet sealant 23 is fitted between the panel 1 </ b> A and the upper portion of the pressing edge 12. Due to the construction of the sealing material 23, the upper portion of the pressing edge 12 is pushed outward by the pressure of the sealing material 23, the fitting portion 22 comes into contact with the locking piece 21d of the cavity portion 21, and the lower portion 24 of the pressing edge 12 is It becomes the vertical attitude | position which contact | abutted to the surface on the outdoor side of the invisible 3A.

このような押縁の取付け構造は、障子１１の押縁１７についても同様に適用される。   Such a structure for attaching the ledge is similarly applied to the ledge 17 of the shoji 11.

本発明においては、無目３Ａの空洞部２１内の底部内面に係止受部２１ｃを設け、その係止受部２１ｃに押縁１２の嵌入部２２の下面に設けた係止突起２２ｄを係止させることで押縁１２の仮止め状態における押縁１２の外れ止めがなされるようにしたので、仮止め状態における押縁１２の落下が防止される。また、このように空洞部２１内で押縁１２を外れ止めをする構造によれば、無目３Ａの外側に押縁の係止部を設けて押縁をその係止部に係止させる場合に比較して、押縁１２の上下幅を狭幅に形成でき、外観向上に寄与することができる。   In the present invention, the latch receiving portion 21c is provided on the inner surface of the bottom of the hollow portion 21 of the seamless 3A, and the latch protrusion 22d provided on the lower surface of the fitting portion 22 of the presser 12 is locked to the latch receiving portion 21c. By doing so, the pressing edge 12 is prevented from coming off in the temporarily fixed state of the pressing edge 12, so that the falling of the pressing edge 12 in the temporarily fixed state is prevented. Further, according to the structure in which the pressing edge 12 is prevented from coming off in the hollow portion 21 as compared with the case where the pressing edge locking portion is provided on the outer side of the intangible 3A and the pressing edge is locked to the locking portion. Thus, the vertical width of the pressing edge 12 can be formed narrow, which can contribute to the appearance improvement.

本発明を実施する場合、無目３Ａ、横枠１４、押縁１２、１７の具体的構造や組み合わせ構造などについては上記実施の形態に限らず、種々の変更、付加が可能である。   When practicing the present invention, the specific structure or combination structure of the intangible 3A, the horizontal frame 14, and the pressing edges 12 and 17 is not limited to the above embodiment, and various changes and additions are possible.
