Description

本発明は、ビル等の外壁部分において、板ガラスなどのパネルを直接的に支持するカーテンウォール構造に係り、詳しくはフレーム枠状のパネル支持部材を有さず、パネルの四隅等を直接支持するパネル支持装置により、外観的にパネルのみによって外壁面を構成するようにするとともに、該パネル支持装置は、上下方向に隣接するパネル支持装置同士を連結する吊りロッド及び／又は水平方向に隣接するパネル支持装置同士を連結するタイロッドにより相互に連結されたカーテンウォールにおける前記ロッドの連結構造に関する。   The present invention relates to a curtain wall structure that directly supports a panel such as a sheet glass at an outer wall portion of a building or the like, and more specifically, a panel that directly supports four corners of a panel without a frame frame-like panel support member. The outer wall surface is configured by the panel only by the external appearance of the support device, and the panel support device is a suspension rod for connecting the panel support devices adjacent in the vertical direction and / or the panel support adjacent in the horizontal direction. The present invention relates to a connecting structure of the rods in a curtain wall connected to each other by tie rods connecting the devices.

近年は、カーテンウォール構造の多様化によって、フレーム枠状のパネル支持材を有さず、パネル（主として板ガラス）の４隅、または４隅及び側縁の一部を直接支持することによりパネルのみによって外壁面を構成するフレームレス工法が普及しつつある。フレームレス工法のパネル支持構造としては、従来より種々の構造が提案されている。   In recent years, with the diversification of the curtain wall structure, there is no frame frame-like panel support material, and only the panel by directly supporting the four corners of the panel (mainly plate glass) or the four corners and part of the side edges. The frameless construction method that constitutes the outer wall surface is spreading. Various structures have been proposed as a panel support structure for the frameless method.

近時では例えば、下記特許文献１には、図１０に示されるように、各パネルＰ、Ｐ…の縦目地に対応する室内側に、パネルのコーナー交点部に配置されるパネル支持装置６０，６０…と、これら各パネル支持装置６０，６０…から室内側に向けて斜め上方及び斜め下方に延びる斜材６４，６４…と、前記斜材６４，６４の連結部に配置される室内側斜材連結金物６１，６１…と、前記パネル支持装置６０，６０…に挿通状態で配置され、各パネル支持装置６０，６０…を吊持する室外側ケーブル６５と、前記各室内側斜材連結金物６１，６１…に挿通状態で配置されるとともに、各室内側斜材連結金物６１，６１…を吊持する室内側ケーブル６６とからなるカーテンウォール支持装置がそれぞれ設けられ、各パネルＰ、Ｐ…が支持されたカーテンウォール構造が開示されている。なお、前記室外側ケーブル６５及び室内側ケーブル６６は、上下端がそれぞれケーブル定着装置６７，６８（下端側のみ図示）に固定されており、所定の緊張力が導入されるようになっているとともに、前記パネル支持装置６０，６０同士はタイロッドにより相互に連結されている（以下、先行例１という）。
特開２００６−２８３４７８号公報 Recently, for example, in Patent Document 1 below, as shown in FIG. 10, panel support devices 60, which are arranged at corner intersections of panels on the indoor side corresponding to the vertical joints of the panels P, P. .., Diagonal members 64, 64... Extending diagonally upward and diagonally downward from the respective panel support devices 60, 60..., And indoor diagonals disposed at the connecting portions of the diagonal members 64, 64. Are connected to the panel support devices 60, 60, and the outdoor cable 65 is used to suspend the panel support devices 60, 60. .. Are arranged in a state of being inserted through 61, 61..., And are provided with curtain wall support devices including indoor side cables 66 for suspending the respective interior side diagonal member connection hardware 61, 61. Car supported Cornwall structure is disclosed. The outdoor cable 65 and the indoor cable 66 have upper and lower ends fixed to cable fixing devices 67 and 68 (only the lower end side is shown), respectively, so that a predetermined tension is introduced. The panel support devices 60 and 60 are connected to each other by tie rods (hereinafter referred to as the first example).
JP 2006-283478 A

しかしながら、地震荷重などを受けた際に、パネルの相関変位に伴い、前記パネル支持装置６０がロッキング（揺動）や相対的な位置ズレを起こすと、剛結されているタイロッドに曲げが導入され、タイロッドが変形したり、破損することが懸念されるなどの問題があった。   However, when the panel support device 60 is rocked (swinged) or relatively displaced due to the relative displacement of the panel when subjected to an earthquake load or the like, bending is introduced into the rigidly connected tie rod. There was a problem that the tie rod was deformed or damaged.

そこで本発明の主たる課題は、建物外壁部分に上下左右方向に隣接配置されるパネルを、該パネルの隅部同士が突き合わされるコーナー交点部に配置されるパネル支持装置によって支持するとともに、前記パネル支持装置は、上下方向に隣接するパネル支持装置同士を連結する吊りロッド及び／又は水平方向に隣接するパネル支持装置同士を連結するタイロッドにより相互に連結されたカーテンウォールにおいて、地震荷重を受けた際にも、前記ロッドに曲げを導入させることが無いロッド連結構造を提供することにある。   Therefore, a main problem of the present invention is to support a panel that is disposed adjacent to the building outer wall portion in the vertical and horizontal directions by a panel support device that is disposed at a corner intersection where the corners of the panel abut each other. The support device is subjected to an earthquake load on a curtain wall connected to each other by a suspension rod that connects panel support devices adjacent in the vertical direction and / or a tie rod that connects panel support devices adjacent in the horizontal direction. Another object is to provide a rod connection structure that does not introduce bending into the rod.

前記課題を解決するために請求項１に係る本発明として、建物外壁部分に上下左右方向に隣接配置されるパネルを、該パネルの隅部同士が突き合わされるコーナー交点部に配置されるパネル支持装置によって支持するとともに、前記パネル支持装置は、上下方向に隣接するパネル支持装置同士を連結する吊りロッド及び／又は水平方向に隣接するパネル支持装置同士を連結するタイロッドにより相互に連結されたカーテンウォールにおいて、
前記パネル支持装置とロッドとの連結構造は、前記ロッドの端部に、ロッド面側に面内方向に沿って曲面を形成した抜止め部材を設けるとともに、前記パネル支持装置側に、ロッド挿通部を形成するとともに、その奥側に前記抜止め部材の嵌込み空間を形成し、前記抜止め部材を前記嵌込み空間に嵌合させるように前記ロッドをパネル支持装置に連結し、前記ロッドとロッド挿通部との遊間内で前記ロッドを面内方向に揺動可能としたことを特徴とするカーテンウォールにおけるロッド連結構造が提供される。 In order to solve the above-mentioned problem, as the present invention according to claim 1, a panel support that is arranged adjacent to a building outer wall portion in the vertical and horizontal directions is arranged at a corner intersection where the corners of the panel abut each other. The panel support device is supported by a device, and the panel support device is connected to each other by a suspension rod that connects panel support devices adjacent in the vertical direction and / or a tie rod that connects panel support devices adjacent in the horizontal direction. In

And a fitting space for the retaining member is formed on the back side of the rod insertion portion on the panel support device side, and the retaining member is fitted in the fitting space. By connecting the rod to the panel support device, the rod can be swung in the in-plane direction. Therefore, even when an earthquake load is applied, the rod is not bent.

なお、この場合、前記ロッド挿通部とロッドとの間に面外方向の遊間を形成するようにすれば、仮にパネル支持装置同士が面外方向に位置ズレしたとしても、ロッドに曲げが導入されないようにすることができる。   In this case, if a gap in the out-of-plane direction is formed between the rod insertion portion and the rod, even if the panel support devices are misaligned in the out-of-plane direction, bending is not introduced into the rod. Can be.

請求項２に係る本発明として、前記パネル支持装置側において、前記ロッド挿通部と嵌込み空間との境界部に前記抜止め部材の曲面と摺動する曲面状の座面を形成してある請求項１記載のカーテンウォールにおけるロッド連結構造が提供される。   According to a second aspect of the present invention, on the panel support device side, a curved seat surface that slides on the curved surface of the retaining member is formed at the boundary between the rod insertion portion and the fitting space. A rod coupling structure in a curtain wall according to Item 1 is provided.

上記請求項２記載の発明は、ロッド挿通部と嵌込み空間との境界部に、抜止め部材の曲面と摺動する曲面状の座面を形成することにより、ロッドの揺動動作を円滑に行うことができる。   According to the second aspect of the present invention, the rocking motion of the rod can be smoothly performed by forming a curved seat surface that slides on the curved surface of the retaining member at the boundary between the rod insertion portion and the fitting space. It can be carried out.

請求項３に係る本発明として、前記嵌込み空間内において、該嵌込み空間の底面と抜止め部材との間に遊間を形成してある請求項１，２いずれかに記載のカーテンウォールにおけるロッド連結構造が提供される。   A rod in a curtain wall according to any one of claims 1 and 2, wherein a gap is formed between the bottom surface of the fitting space and a retaining member in the fitting space.
