Description

【０００１】
【発明の属する技術分野】
本発明は、ゴンドラガイド部を有するユニット式カーテンウオールに関する。
【０００２】
【従来の技術】
ユニット式カーテンウオールとしては、枠体にガラスや障子を取付けた複数のカーテンウオールユニットを建物躯体に上下、左右方向に連続して取付けたものが知られている。
このようなユニット式カーテンウオールにおいてはゴンドラを昇降ガイドするゴンドラガイド部を設けたものが提案されている。
【０００３】
例えば、実開昭５９−１７５５０８号公報に開示されたように、左右に隣接した一方のカーテンウオールユニットの枠体を形成する縦枠と他方のカーテンウオールユニットの枠体を形成する縦枠でゴンドラガイド部を形成し、このゴンドラガイド部に沿ってゴンドラガイドを昇降案内するようにしたユニット式カーテンウオールが提案されている。
【０００４】
【発明が解決しようとする課題】
前述のユニット式カーテンウオールであると、ゴンドラが強風や地震などで左右に振れ動いた時にゴンドラガイドが左右一方の枠体の縦枠に衝突する。このために左右一方の枠体の縦枠に大きな衝撃力が作用するから、その縦枠が変形する恐れがある。
【０００５】
そこで、本発明は前述の課題を解決できるようにしたユニット式カーテンウオールを提供することを目的とする。
【０００６】
【課題を解決するための手段】
第１の発明は、左右に隣接する一方のカーテンウオールユニットの縦枠と他方のカーテンウオールユニットの縦枠との間にゴンドラガイド部を有し、
前記左右に隣接する一方のカーテンウオールユニットの縦枠と他方のカーテンウオールユニットの縦枠を連結部材で連結したユニット式カーテンウオールにおいて、
前記連結部材は、第１連結部材と第２連結部材を備え、この第１連結部材と第２連結部材は、相互に面内方向に動かないように係合する形状で、
前記第１連結部材を隣接した一方のカーテンウオールユニットの縦枠に取付け、第２連結部材を隣接した他方のカーテンウオールユニットの縦枠に取付け、この第１連結部材と第２連結部材を係合して一方の縦枠と他方の縦枠を連結したことを特徴とするユニット式カーテンウオールである。
【０００７】
第２の発明は、第１の発明において、縦枠はゴンドラガイド部を形成する室外寄り外向凹部と、この室外寄り外向凹部の室内側部と隣接した連結部材取付用の室内寄り外向凹部を有し、この室内寄り外向凹部に連結部材の第１連結部材、第２連結部材を取付けたユニット式カーテンウオールである。
【０００９】
【作用】
第１の発明によれば、ゴンドラのゴンドラガイドをゴンドラガイド部に沿って移動自在に支承することで、ゴンドラをゴンドラガイド部に沿って上下動することができる。
前述のゴンドラが強風や地震等で左右に振れ動いてゴンドラが左右に隣接する一方のカーテンウオールユニットの縦枠に衝突すると、その縦枠に衝撃力が作用して左右に動くことになるが、その縦枠に取付けた第１連結部材と他方のカーテンウオールユニットの縦枠に取付けた第２連結部材が相互に面内方向に動かないように係合しているので、他方のカーテンウオールユニットの縦枠も同じ方向に動くことになる。
このために、縦枠に作用する衝撃力の一部が連結部材を介して他方のカーテンウオールユニットの縦枠に伝わり、衝撃力はゴンドラガイド部を形成する左右に隣接した２つの縦枠に分散する。
これによって、縦枠の変形を防止できる。
また、左右に隣接した一方のカーテンウオールユニットの縦枠に第１連結部材を取付け、他方のカーテンウオールユニットの縦枠に第２連結部材を取付け、その両方のカーテンウオールユニットを建物躯体に取付けることで第１連結部材と第２連結部材が互いに係合されるので、カーテンウオールユニットの施工が容易である。
【００１０】
第２の発明によれば、連結部材はゴンドラガイドよりも室内側に取付けてあるから、その連結部材が室外から目視され難く外観の見栄えが良い。
また、縦枠のゴンドラガイド部を形成する部分と連結部材を取付ける部分が隣接し、ゴンドラの衝突により、縦枠のゴンドラガイド部を形成する部分に作用する衝撃力が連結部材を介して２つの縦枠に効率良く伝わるから、その衝撃力で縦枠が変形することを確実に防止できる。
【００１２】
【発明の実施の形態】
図１に示すように、左右の縦枠１と上枠２と下枠３と横中骨４で方形状の枠体５を形成し、その枠体５にガラスや障子などのパネル体６を装着してカーテンウオールユニット７とする。
このカーテンウオールユニット７を上下・左右に連続して建物躯体に取付けてユニット式カーテンウオールを形成する。
【００１３】
左右に隣接する一方のカーテンウオールユニット７の枠体５の縦枠１と他方のカーテンウオールユニット７の枠体５の縦枠１との間にゴンドラガイド部８を形成し、このゴンドラガイド部８は上下のカーテンウオールユニット７で連続する。
【００１４】
前記隣接したカーテンウオールユニット７の縦枠１同志が連結部材９で連結してある。
これによって、ゴンドラが強風や地震等で左右に振れ動いてゴンドラガイドが一方の縦枠１に衝突した時に、その一方の縦枠１に作用する衝撃力の一部が連結部材９を介して他方の縦枠１に伝達する。これにより衝撃力を左右の縦枠１で支承することになるので、縦枠１が変形する恐れがない。
【００１５】
次に各部の具体形状を説明する。
図２に示すように、左右の縦枠１は室外側内向凹部１０、室外寄り外向凹部１１、室内寄り外向凹部１２、室内側外向凹部１３を有する同一断面形状で、左右反転して用いられ、相対向した室外寄り外向凹部１１でゴンドラガイド部８を形成し、そのゴンドラガイド部８に沿ってゴンドラガイド１４が上下動する。図２に示す実施の形態では室外寄り外向凹部１１に断面Ｌ字状のゴンドラガイドアタッチメント１５が取付けてあるが、このゴンドラガイドアタッチメント１５は取付けなくとも良い。
【００１６】
前記一方の縦枠１の室内寄り外向凹部１２には中空形状の縦枠アタッチメント１６が取付けてある。この縦枠アタッチメント１６が他方の縦枠１の室内寄り外向凹部１２に嵌まり込んでレインバリヤを形成している。つまり、左右の縦枠１を同一断面形状としたので、その左右の縦枠１同志を嵌め合ってレインバリヤを形成できないので、一方の縦枠１に縦枠アタッチメント１６を取付けて同一断面形状の縦枠１を用いてレインバリヤを形成できるようにしてある。
【００１７】
前記連結部材９は一方の縦枠１の室内寄り外向凹部１２の底面１２ａに固着した第１連結部材２０と、他方の縦枠１の室内寄り外向凹部１２の底面１２ａに固着した第２連結部材２１で形成してある。前記第１連結部材２０は取付片２２と横向片２３と係止片２４で室内側に向けてコ字状で取付片２２が一方の縦枠１の室内寄り外向凹部１２の底面１２ａにボルト２５で固着してある。第２連結部材２１は取付片２６と横向片２７と係止片２８で室外側に向けてコ字状で、その取付片２５が他方の縦枠１の室内寄り外向凹部１２の底面１２ａにボルト２９で固着してある。
【００１８】
前記第１連結部材２０の係止片２４と第２連結部材２１の係止片２８が面外方向にオーバーラップし、一方の縦枠１が面内方向に変位すると係止片２４，２８同志が面内方向に接するようにしてある。なお、実施の形態においては、第１連結部材９の係止片２４に丸棒３０が固着してあり、この丸棒３０が第２連結部材２１の係止片２８と接するようにしてある。
【００１９】
前述のように一方の縦枠１の室内寄り外向凹部１２には縦枠アタッチメント１６が取付けてあるので、図３と図４に示すように、この縦枠アタッチメント１６の取付側板１６ａに第１切欠開口部３１を形成して第１連結部材２０の取付片２２を第１切欠開口部３１から一方の縦枠１の室内寄り外向凹部１２の底面１２ａに取付けできるようにしてある。
【００２０】
また、縦枠アタッチメント１６の先端側板１６ｂに第２切欠開口部３２を形成し、この第２切り欠き開口部３２から第２連結部材２１の横向片２７と係止片２８を縦枠アタッチメント１６の中空部内に挿入できるようにしてある。
【００２１】
前記第１切欠開口部３１は第１連結部材２０の取付片２２が挿通する程度の大きさである。前記第２切欠開口部３２の開口幅（面外方向寸法）は第２連結部材２１の幅より若干大きく、上下方向長さは第１連結部材２０の上下長さと第２連結部材２１の上下長さの和よりも若干大きい。この第２切欠開口部３２の下端開口縁は第１切欠開口部３１の下端開口縁とほぼ同一高さ位置で、第２切欠開口部３２の上端開口縁は第１切欠開口部３１の上端開口縁よりも上方位置で、第２連結部材２１を第１連結部材２０と干渉しないように縦枠アタッチメント１６内に挿入できるようにしてある。
【００２２】
このようであるから、第１連結部材２０を取付けたカーテンウオールユニット７を建物躯体に取付けた後に、第２連結部材２１を取付けたカーテンウオールユニット７を図３で矢印ａで示すように移動してその第２連結部材２１を縦枠アタッチメント１６の第２切欠開口部３２より内部に挿入し、そのカーテンウオールユニットを図３で矢印ｂで示すように下方に移動して係止片２４，２８相互を面外方向にオーバーラップさせて、そのカーテンウオールユニットを建物躯体に取付けできる。
【００２３】
次に第２の実施の形態を説明する。
図５に示すように、一方の縦枠１の室内寄り外向凹部１２を形成する部分に室外寄り突出片４０、室内寄り突出片４１が一体的に設けてある。他方の縦枠１の室内寄り外向凹部１２には室外寄り凹部４２と室内寄り凹部４３が形成してある。前記室外寄り突出片４０を室外寄り凹部４２に嵌め込むと共に、室内寄り突出片４１を室内寄り凹部４３に嵌め込んでレインバリヤを形成してある。
【００２４】
第１連結部材２０は図５と図６に示すように取付け片４４と横片４５を備え、その横片４５に上向きの凹陥部４６が形成されて係合部としてある。この取付け片４４が一方の縦枠１の室内寄り外向き凹部１２の底面１２ａにボルト４７で取付けてある。
【００２５】
第２連結部材２１は図５と図６に示すように取付け片４８と横片４９を備え、この横片４９に下向きに突片５０が形成されて係合部としてある。横片４９を他方の縦枠１の室内寄り外向凹部１２の底面１２ａにボルト５１で取付けてある。
【００２６】
第２連結部材２１の突片５０が第１連結部材２０の凹陥部４６に嵌まり込んで第１連結部材２０と第２連結部材２１が面内方向に動かないように連結されて連結部材９を形成する。
【００２７】
このようであるから、第１連結部材２０を取付けたカーテンウオールユニットを建物躯体に取付けた後に、第２連結部材２１を取付けたカーテンウオールユニットを上から下に移動して建物躯体に取付けることで第１連結部材２０と第２連結部材２１を連結できる。
【００２８】
以上の実施の形態では連結部材９を第１連結部材２０と第２連結部材２１で形成し、第１・第２連結部材２０，２１を縦枠１にあらかじめそれぞれ取付け、カーテンウオールユニットを建物躯体に取付けることで第１連結部材２０と第２連結部材２１を面内方向に動かないよう連結したが、連結部材９を一体形状としても良い。例えばカーテンウオールユニットを建物躯体に取付けた後に隣接した２つの縦枠１に１つの連結部材９をボルト等で取付ける。
【００２９】
【発明の効果】
請求項１に係る発明によれば、ゴンドラのゴンドラガイドをゴンドラガイド部に沿って移動自在に支承することで、ゴンドラをゴンドラガイド部に沿って上下動することができる。
前述のゴンドラが強風や地震等で左右に振れ動いてゴンドラが左右に隣接する一方のカーテンウオールユニットの縦枠に衝突すると、その縦枠に衝撃力が作用して左右に動くことになるが、その縦枠に取付けた第１連結部材と他方のカーテンウオールユニットの縦枠に取付けた第２連結部材が相互に面内方向に動かないように係合しているので、他方のカーテンウオールユニットの縦枠も同じ方向に動くことになる。
このために、縦枠に作用する衝撃力の一部が連結部材を介して他方のカーテンウオールユニットの縦枠に伝わり、衝撃力はゴンドラガイド部を形成する左右に隣接した２つの縦枠に分散する。
これによって、縦枠の変形を防止できる。
また、左右に隣接した一方のカーテンウオールユニットの縦枠に第１連結部材を取付け、他方のカーテンウオールユニットの縦枠に第２連結部材を取付け、その両方のカーテンウオールユニットを建物躯体に取付けることで第１連結部材と第２連結部材が互いに係合されるので、カーテンウオールユニットの施工が容易である。
【００３０】
請求項２に係る発明によれば、連結部材はゴンドラガイドよりも室内側に取付けてあるから、その連結部材が室外から目視され難く外観の見栄えが良い。
また、縦枠のゴンドラガイド部を形成する部分と連結部材を取付ける部分が隣接し、ゴンドラの衝突により、縦枠のゴンドラガイド部を形成する部分に作用する衝撃力が連結部材を介して２つの縦枠に効率良く伝わるから、その衝撃力で縦枠が変形することを確実に防止できる。

The unit type curtain wall is characterized in that one vertical frame and the other vertical frame are connected.
[0007]
According to a second invention, in the first invention, the vertical frame has an outdoor outward concave portion that forms a gondola guide portion, and an indoor outward outward recess for attaching the connecting member adjacent to the indoor side portion of the outdoor outward recess. And it is the unit type curtain wall which attached the 1st connection member of the connection member, and the 2nd connection member to this indoor side outward recessed part.
[0009]
[Action]
According to the first aspect, the gondola can be moved up and down along the gondola guide portion by supporting the gondola guide of the gondola so as to be movable along the gondola guide portion.
When the above-mentioned gondola swings left and right due to strong winds, earthquakes, etc., and the gondola collides with the vertical frame of one curtain wall unit adjacent to the left and right , impact force acts on the vertical frame and moves left and right, The first connecting member attached to the vertical frame and the second connecting member attached to the vertical frame of the other curtain wall unit are engaged with each other so as not to move in the in-plane direction. The vertical frame will move in the same direction.
For this reason, part of the impact force acting on the vertical frame is transmitted to the vertical frame of the other curtain wall unit via the connecting member, and the impact force is distributed to the two vertical frames adjacent to the left and right that form the gondola guide portion. To do.
Thereby, deformation of the vertical frame can be prevented.
Also, the first connecting member is attached to the vertical frame of one curtain wall unit adjacent to the left and right, the second connecting member is attached to the vertical frame of the other curtain wall unit, and both the curtain wall units are attached to the building frame. Since the first connecting member and the second connecting member are engaged with each other, the construction of the curtain wall unit is easy.
[0010]
According to the second aspect of the invention, since the connecting member is attached to the indoor side of the gondola guide , the connecting member is difficult to be seen from the outside and has a good appearance.
In addition, the part that forms the gondola guide part of the vertical frame and the part that attaches the connecting member are adjacent to each other, and the impact force that acts on the part that forms the gondola guide part of the vertical frame due to the collision of the gondola Since it is efficiently transmitted to the vertical frame, it is possible to reliably prevent the vertical frame from being deformed by the impact force.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, a rectangular frame 5 is formed by left and right vertical frames 1, an upper frame 2, a lower frame 3, and a horizontal central bone 4, and a panel body 6 such as glass or a shoji is attached to the frame 5. The curtain wall unit 7 is installed.
This curtain wall unit 7 is attached to the building frame continuously in the vertical and horizontal directions to form a unit type curtain wall.
