Abstract

PROBLEM TO BE SOLVED: To provide a highly earthquake resistant glass panel device that withstands an inter-layer deformation angle of 1/40, a seismic intensity of 7, and a ceiling surface acceleration of 2.2G, preventing for certain falling and damaging of a glass panel even when an especially large inter-layer displacement has occurred.SOLUTION: A highly earthquake resistant glass panel device retains a glass panel stably even in a locking state, in which a column is slanted as it tracks an inter-layer displacement at a time of earthquake. A glass panel 6 includes a glass plate 7 and a frame body 8. The frame body has vertical frame members 9 on both sides, an upper horizontal frame member 10 and a lower horizontal frame member 1 connected with a connection metal fitting 12, and has a holding groove 13 formed along an inner peripheral part for holding edges of the glass plate. The frame body is fixed on a column 5 on at least one side, to allow the frame body to get deformed as it tracks the slanting of the column, with the connection metal fitting at a center. Furthermore, the holding groove on the frame body is sufficiently deep so as to prevent the edges of the glass plate from coming in contact with a bottom part of the holding groove, when the frame body is deformed.SELECTED DRAWING: Figure 7

Description

本発明は、高耐震性ガラスパネル装置に係わり、更に詳しくは大きな層間変位にもガラス板の脱落や破損の恐れが無い高耐震性ガラスパネル装置に関するものである。   The present invention relates to a highly earthquake-resistant glass panel device, and more particularly to a highly earthquake-resistant glass panel device in which there is no fear of dropping or breaking of a glass plate even with a large interlayer displacement.
通常、オフィスビル等は、複数のスラブで各階が形成され、上スラブの下面側には吊り天井構造体が構築され、下スラブの上面側にはフロア構造体が構築され、構造壁で囲まれた空間を間仕切装置で適宜に区画されている。通常、吊り天井構造体は、上スラブから垂下した吊支部材(吊りボルト)によって、縦横に張り巡らした天井支持レールを吊下げ状に保持し、該天井支持レールに天井パネルの周囲を係止する構造である。このような吊り天井構造体を有する室内に天井パネルからフロア構造体にわたって、間仕切パネルやドアパネルを組み合わせた間仕切装置を設置する。ここで、間仕切パネルとして、空間の開放性を高めるために、ガラスパネルを用いることも多い。従来、吊り天井構造体に対する耐震基準はなかったが、東日本大震災によって多くの吊り天井構造体が落下し、破損したことを受けて、天井の耐震性を高める機運が高まり、層間変形角が1/60〜1/40、震度7、天井面加速度が2.2Gに耐えることが必要と考えられる。それに応じてガラスパネルにも同様の高耐震性が要求されるようになった。   Normally, an office building or the like is formed of a plurality of slabs and each floor is formed, a suspended ceiling structure is constructed on the lower surface side of the upper slab, and a floor structure is constructed on the upper surface side of the lower slab and surrounded by a structural wall. The space is appropriately partitioned by a partition device. Usually, a suspended ceiling structure holds a ceiling support rail suspended vertically and horizontally by suspension support members (suspending bolts) suspended from the upper slab, and locks the periphery of the ceiling panel to the ceiling support rail It is a structure to do. A partition device combining partition panels and door panels is installed in the room having such a suspended ceiling structure from the ceiling panel to the floor structure. Here, a glass panel is often used as the partition panel in order to increase the openness of the space. Conventionally, there was no earthquake resistance standard for suspended ceiling structures, but due to the fact that many suspended ceiling structures were dropped and damaged by the Great East Japan Earthquake, the momentum to improve the earthquake resistance of the ceiling increased, and the interlayer deformation angle was 1 / It is considered necessary to withstand 60 to 1/40, seismic intensity 7, and ceiling surface acceleration 2.2G. Correspondingly, glass panels are required to have the same high earthquake resistance.
一方、従来から天井に取付けた天レールと床面に敷設した地レールの間に、間隔を置いて複数の支柱を立設し、隣接する支柱間に枠体を介してガラス板を保持した構造のガラスパネル装置は各種提供されている。ここで、前記ガラス板は、床面から天井に至る一枚物や上下に複数に分割されたタイプのものがあるが、本発明では一枚物のガラス板を有するガラスパネルを対象としている。   On the other hand, a structure in which a plurality of columns are erected at intervals between a ceiling rail conventionally attached to the ceiling and a ground rail laid on the floor, and a glass plate is held between adjacent columns via a frame Various glass panel devices are provided. Here, although the said glass plate has the thing of the type divided | segmented into the one piece from a floor surface to a ceiling, and the upper and lower sides, in this invention, the glass panel which has a single piece glass plate is made into object.
ガラス板を保持する構造としては、互いに連結して強度を高めた枠体をガラス板の周囲に密嵌し、あるいは両面粘着テープで枠体とガラス板とを粘着して固定して剛性の高いガラスパネルとし、該ガラスパネルの枠体を両側支柱に係止具で係止する構造(特許文献1参照)、あるいは前記ガラスパネルの枠体を両側支柱、天レール及び地レールにネジ止めする構造(特許文献2参照)がある。更に、両側支柱、天レール及び地レールに縦枠と横枠を取付け、該縦枠と横枠に設けた凹溝、あるいは両側支柱、天レール及び地レールに直接設けた凹溝を利用してガラス板の周囲を、パッキンを介して保持する構造のものが一般的である(特許文献3参照)。   As a structure to hold the glass plate, a frame body that is connected to each other to enhance the strength is tightly fitted around the glass plate, or the frame body and the glass plate are adhered and fixed with a double-sided adhesive tape, and the rigidity is high. A structure in which a glass panel and the frame of the glass panel are locked to both side posts by a locking tool (see Patent Document 1), or a structure in which the frame of the glass panel is screwed to the side columns, the top rail, and the ground rail. (See Patent Document 2). Furthermore, vertical frames and horizontal frames are attached to both side supports, top rails and ground rails, and concave grooves provided on the vertical frames and horizontal frames, or concave grooves provided directly on both side posts, top rails and ground rails are used. The structure of holding | maintaining the circumference | surroundings of a glass plate through packing is common (refer patent document 3).
しかし、地震時の層間変位に伴って支柱が大きくロッキングした際に、ガラスパネルの枠体を係止具で支柱に係止する構造のものは、ガラスパネルが支柱に対して競り上がり、大きく変位するとガラスパネルが係止具から外れることになり、またガラスパネルの枠体を両支柱に固定する構造のものは、枠体も支柱と一体となって傾斜するので、ガラス板と枠体の間で大きな応力が作用し、ガラス板が枠体から外れる、若しくはガラス板が破損するといったことも想定される。一方、ガラス板の周囲を、両側支柱、天レール及び地レールに取付けた縦枠と横枠の凹溝、あるいは両側支柱、天レール及び地レールに設けた凹溝にパッキンを介して保持する構造では、地震時の層間変位に伴って支柱が大きくロッキングした際に、パッキンが外れてガラス板が脱落したり、ガラス板が縦枠や支柱に衝突して破損することが想定される。   However, when the struts are largely locked due to the interlayer displacement during the earthquake, the glass panel frame is abutted against the struts with a structure that locks the frame of the glass panel to the struts. Then, the glass panel will come off from the locking tool, and the structure that fixes the frame of the glass panel to both columns will also incline with the column, so the gap between the glass plate and the frame It is also assumed that a large stress acts and the glass plate is detached from the frame or the glass plate is damaged. On the other hand, a structure in which the periphery of the glass plate is held via packings in the recessed grooves of the vertical and horizontal frames attached to both side supports, the top rail and the ground rail, or the recessed grooves provided on both side supports, the top rail and the ground rail. In this case, it is assumed that when the struts are largely locked in accordance with the interlayer displacement during the earthquake, the packing is removed and the glass plate is dropped, or the glass plate collides with the vertical frame or the strut and is damaged.
尚、特許文献4はガラスパネル装置に関するものではないが、建築物を構成する柱、梁、土台などの架構の内側面に枠材を配置し、かつ、これら枠材の内側面に略矩形状の弾性部材を密着させた建築物の壁面構造であって、前記弾性部材の外寸よりも一回り大きく、かつ前記架構の内寸よりも一回り小さい平板状の面材を用意するとともに、この面材を前記架構の内面に接触しないように前記弾性部材の外側に密着させた制振機能を備えた建築物の壁面構造が開示されている。地震が生じ架構に水平移動力が生じると、周囲4つの枠材に対して面材が相対的に水平方向に移動し、移動した方向の柱部材の内面に面材が当接することにより、面材は土台と梁とで押しつけられ、面材は全体的な面の剛性によって、壁の変形を抑制するのである。また、このときの圧縮力は、弾性部材、面材ならびに枠材を介して柱、土台、梁などの周囲の枠体に分散して逃がすことができるというものである。   In addition, although patent document 4 is not related with a glass panel apparatus, frame material is arrange | positioned to the inner surface of frames, such as a pillar, a beam, and a foundation which comprise a building, and the substantially rectangular shape is formed on the inner surface of these frame materials. A wall surface structure of a building in which the elastic member is closely attached, and a flat plate-like face material that is slightly larger than the outer dimension of the elastic member and smaller than the inner dimension of the frame, A wall surface structure of a building having a damping function in which a face material is brought into close contact with the outside of the elastic member so as not to contact the inner surface of the frame is disclosed. When an earthquake occurs and horizontal movement force is generated in the frame, the face material moves in the horizontal direction relative to the surrounding four frame members, and the face material comes into contact with the inner surface of the column member in the moved direction. The material is pressed by the base and the beam, and the face material suppresses the deformation of the wall by the overall rigidity of the surface. The compressive force at this time can be dispersed and released to surrounding frames such as columns, foundations, and beams via elastic members, face materials, and frame materials.

以上にしてなる請求項1に係る発明の高耐震性ガラスパネル装置は、天井と床面間に所定間隔を隔てて立設した支柱にガラスパネルを保持し、地震時の層間変位に追従して前記支柱が傾斜してロッキング状態になっても前記ガラスパネルを安定に保持し得る高耐震性ガラスパネル装置において、前記ガラスパネルは、ガラス板と枠体とからなり、該枠体は、両側縦枠、上横枠及び下横枠とを連結金具で連結するとともに、前記ガラス板の周囲を保持する保持溝を内周部に備え、前記枠体を少なくとも一側の前記支柱に固定し、前記枠体が連結金具を中心に支柱の傾斜に追従して変形可能であるとともに、該枠体の変形時にガラス板の周囲が前記保持溝の底部に当接しないように該保持溝の深さを十分に確保してなるので、地震時の層間変位に追従して前記支柱が傾斜してロッキング状態になっても、ガラスパネルの枠体が支柱の傾斜に伴って変形するだけであり、ガラス板の周縁部は枠体の保持溝内で変位を許容して余裕をもって保持されるので、ガラス板が枠体に衝突して破損することがなく、またガラス板の脱落もなく、安定に保持することができる。   The highly earthquake-resistant glass panel device according to the first aspect of the present invention as described above holds the glass panel on a column that is erected with a predetermined interval between the ceiling and the floor, and follows the interlayer displacement during an earthquake. In the high earthquake-resistant glass panel device capable of stably holding the glass panel even when the support column is inclined and locked, the glass panel is composed of a glass plate and a frame, and the frame is vertically arranged on both sides. The frame, the upper horizontal frame and the lower horizontal frame are connected by a connecting metal fitting, and a holding groove for holding the periphery of the glass plate is provided in an inner peripheral portion, and the frame body is fixed to the support column on at least one side, The frame body can be deformed following the inclination of the column with the connecting metal fitting as the center, and the depth of the holding groove is set so that the periphery of the glass plate does not contact the bottom of the holding groove when the frame body is deformed. Since it is sufficiently secured, it can be used for displacement between layers during an earthquake. Therefore, even if the support column is inclined and locked, the frame of the glass panel only deforms with the inclination of the support column, and the peripheral edge of the glass plate is allowed to be displaced in the holding groove of the frame. Since the glass plate does not collide with the frame body and is not damaged, and the glass plate is not dropped off, the glass plate can be stably held.
請求項2によれば、前記枠体の保持溝内におけるガラス板の変位量が、50mm以上、105mm以下であるので、支柱の傾斜に伴って枠体が平行四辺形の状態に大きく変形しても、ガラス板を安定に保持できる許容範囲が広くなり、事実上高い耐震性を付与できる。   According to claim 2, since the displacement amount of the glass plate in the holding groove of the frame body is 50 mm or more and 105 mm or less, the frame body is greatly deformed into a parallelogram state with the inclination of the column. However, the permissible range in which the glass plate can be stably held is widened, and virtually high earthquake resistance can be imparted.
請求項3によれば、前記ガラス板の両側縁部と上縁部に、該ガラス板の端面から表裏両面にわたってスライダーを添設し、該スライダーが前記枠体の保持溝内を摺動してなるので、枠体が平行四辺形の状態に変形する際に、枠体からガラス板への力の伝達を非常に小さくすることができ、ガラス板にかかる応力を小さくできる。   According to claim 3, sliders are provided on both side edges and upper edge of the glass plate from the end surface of the glass plate to both front and back surfaces, and the slider slides in the holding groove of the frame body. Therefore, when the frame is deformed into a parallelogram, the transmission of force from the frame to the glass plate can be made extremely small, and the stress applied to the glass plate can be reduced.
請求項4によれば、前記保持溝の開口縁部内に、前記スライダーを当止してガラス板の該保持溝内からの離脱を防止する規制段部を形成してなるので、枠体が平行四辺形の状態に変形する際に、スライダーが規制段部に当止されてガラス板が枠体から外れることを防止することができる。   According to the fourth aspect of the present invention, since the regulation step portion is formed in the opening edge portion of the holding groove to prevent the glass plate from being detached from the holding groove by holding the slider, the frame body is parallel. It is possible to prevent the glass plate from being detached from the frame body by being brought into contact with the restricting step portion when deforming into a quadrilateral shape.
請求項5によれば、前記枠体は、それぞれ両側縦枠部材、上横枠部材及び下横枠部材を備えるとともに、前記連結金具で連結した表側枠体と裏側枠体とからなり、前記表側枠体は前記保持溝の一側壁面を形成する保持板と該保持溝の底面を一部で形成する基板とを備え、前記裏側枠体は前記保持溝の他側壁面を形成する保持板と前記基板に重合して前記保持溝の横幅を規定する底面板と該底面板から延長した取付板とを備え、前記表側枠体を両支柱間に表側から装着し、下横枠部材の基板の上に沿って敷設した弾性材の上に前記ガラス板を載支し、前記裏側枠体を両支柱間に裏側から装着して前記基板と底面板を重合するとともに、前記表側枠体の保持板と前記裏側枠体の保持板とで前記ガラス板の周縁部を挟み込んだ状態で、前記取付板と基板をネジ止めしてなるので、施工性に優れるとともに、表側枠体と裏側枠体が組み合わさった状態では外観的に一体の枠体となる。   According to claim 5, the frame includes a vertical frame member on both sides, an upper horizontal frame member, and a lower horizontal frame member, and includes a front side frame body and a back side frame body connected by the connecting bracket, and the front side The frame includes a holding plate that forms one side wall surface of the holding groove and a substrate that partially forms a bottom surface of the holding groove, and the back frame includes a holding plate that forms the other side wall surface of the holding groove; A bottom plate that defines a lateral width of the holding groove by overlapping with the substrate and a mounting plate that extends from the bottom plate are mounted from the front side between the support columns, and the substrate of the lower horizontal frame member is mounted. The glass plate is mounted on an elastic material laid along the top, the back frame is attached from both sides between the columns to superpose the substrate and the bottom plate, and the front frame holding plate And the mounting plate in the state where the peripheral edge of the glass plate is sandwiched between the holding plate of the back side frame body Since screwed a plate is excellent in workability, a frame of integral in appearance in a state where the front frame and the back frame are combined.

一般的にオフィスビルは、構造柱や構造壁で支持されたスラブで階に区画され、スラブの下面側に吊り天井構造体を構築し、スラブの上面側に配線空間を備えたフロア構造体を構築している。本実施形態では、前記天井1は吊り天井構造体、前記床面2はフロア構造体に対応する。そして、前記吊り天井構造体(天井1)の下面に取付けた天レール3と前記フロア構造体(床面2)の上面に取付けた地レール4との間に、上端部は前記天レール3、下端部は前記地レール4の変位に追従可能となるように、複数の支柱5,…を所定間隔毎に立設している。   In general, an office building is divided into floors with slabs supported by structural columns and structural walls, a suspended ceiling structure is constructed on the lower surface side of the slab, and a floor structure body having wiring space on the upper surface side of the slab. Is building. In the present embodiment, the ceiling 1 corresponds to a suspended ceiling structure, and the floor 2 corresponds to a floor structure. And between the ceiling rail 3 attached to the lower surface of the suspended ceiling structure (ceiling 1) and the ground rail 4 attached to the upper surface of the floor structure (floor surface 2), the upper end is the ceiling rail 3, The lower end portion is provided with a plurality of support columns 5 at a predetermined interval so as to be able to follow the displacement of the ground rail 4.
図2及び図3に示すように、地震により建物の上スラブと下スラブに層間変位が生じると、前記支柱5,…は左右に傾斜する。層間変形角を最大の1/40とすれば、階高さが4200mmの場合、層間変位は105mmとなり、スラブに追従して運動する耐震性の吊り天井構造体の変位も105mmとなる。つまり、標準的な天井高さ2800mmの天井が床面に対して片側105mm変位することを意味している。図2(b)及び図3(b)に支柱5の下端に対する上端の水平変位をΔDで表している。   As shown in FIGS. 2 and 3, when an interlayer displacement occurs between the upper slab and the lower slab of a building due to an earthquake, the columns 5,. When the interlayer deformation angle is set to 1/40 at the maximum, when the floor height is 4200 mm, the interlayer displacement is 105 mm, and the displacement of the earthquake-resistant suspended ceiling structure that moves following the slab is also 105 mm. That is, this means that a standard ceiling height of 2800 mm is displaced by 105 mm on one side with respect to the floor surface. 2B and 3B, the horizontal displacement of the upper end with respect to the lower end of the column 5 is represented by ΔD.
前記支柱5は、図7に示すように、一側面側が開放した断面略C字形の角型杆体であり、図1に示すように、下端にアジャスター14を装着して前記地レール4の凹溝内に立設し、上端は前記天レール3に適宜な天固定金具15を用いて保持している。また、前記ガラスパネル6は重量が重く、例えば幅900mm、高さ2700mm、厚さ6mmのガラス板7の重量は約35kgもあるので、該ガラスパネル6の下端中央部を、図1及び図6に示すように、前記地レール4の凹溝内でサブアジャスター16を用いて支持している。   As shown in FIG. 7, the support column 5 is a square housing having a substantially C-shaped cross section that is open on one side surface. As shown in FIG. 1, the adjuster 14 is attached to the lower end and the concave groove of the ground rail 4 is installed. The upper end is held on the top rail 3 by using an appropriate top fixing bracket 15. The glass panel 6 is heavy. For example, the glass plate 7 having a width of 900 mm, a height of 2700 mm, and a thickness of 6 mm has a weight of about 35 kg. As shown in FIG. 2, the sub-adjuster 16 is used to support the concave groove of the ground rail 4.
ここで、前記枠体8の保持溝13内におけるガラス板7の変位量が、50mm以上、105mm以下であることが好ましい。耐震性のレベルにもよるが、前述のように水平変位ΔDは最大105mmであるので、前記保持溝13内におけるガラス板7の許容変位量も最大105mmは必要である。しかし、この許容変位量を大きく設定すると、前記縦枠9の横幅がその分だけ広くなるので、意匠的な問題が生じてくる。   Here, it is preferable that the displacement amount of the glass plate 7 in the holding groove 13 of the frame 8 is 50 mm or more and 105 mm or less. Although depending on the level of earthquake resistance, the horizontal displacement ΔD is 105 mm at the maximum as described above, and therefore the allowable displacement of the glass plate 7 in the holding groove 13 is also required to be 105 mm at the maximum. However, if this allowable displacement amount is set to be large, the horizontal width of the vertical frame 9 is increased by that amount, which causes a design problem.
また、前記ガラス板7の両側縁部と上縁部に、該ガラス板7の端面から表裏両面にわたって断面コ字形のスライダー17を添設し、該スライダー17が前記枠体の保持溝13内を摺動するようにしている。尚、前記スライダー17は、前記ガラス板7の板厚よりも若干厚い断面四角形のブロック状のスライダーとし、前記ガラス板7の端面にブロック状スライダーを両端縁が該ガラス板7の表裏両面から若干突出するように配置して接着しても良い。更に、前記保持溝13の開口縁部内に、前記スライダー17を当止してガラス板7の該保持溝13内からの離脱を防止する規制段部18を形成している。尚、前記下横枠11の保持溝13の底部には、図6に示すように、前記ガラス板7を載支するゴム製の弾性材19を敷設している。前記スライダー17には、枠体8が大きく変形してガラス板7の上端部が縦枠9の保持溝13の底部に衝突する場合に、衝撃を吸収する緩衝材としての作用もある。   Further, a slider 17 having a U-shaped cross section is attached to both side edge portions and upper edge portion of the glass plate 7 from the end surface of the glass plate 7 to both the front and back surfaces, and the slider 17 passes through the holding groove 13 of the frame body. I try to slide. The slider 17 is a block-shaped slider having a rectangular cross section that is slightly thicker than the thickness of the glass plate 7, and a block-like slider is provided on the end surface of the glass plate 7, and both edges are slightly from both the front and back surfaces of the glass plate 7. You may arrange | position and adhere | attach so that it may protrude. Further, a regulation step portion 18 is formed in the opening edge portion of the holding groove 13 to prevent the glass plate 7 from being detached from the holding groove 13 by stopping the slider 17. As shown in FIG. 6, a rubber elastic material 19 that supports the glass plate 7 is laid on the bottom of the holding groove 13 of the lower horizontal frame 11. The slider 17 also has a function as a buffer material that absorbs an impact when the frame body 8 is greatly deformed and the upper end portion of the glass plate 7 collides with the bottom portion of the holding groove 13 of the vertical frame 9.
更に詳しくは、前記枠体8は、それぞれアルミ押出し型材で作製した両側縦枠部材9A,9B、上横枠部材10A,10B及び下横枠部材11A,11Bを備えるとともに、前記連結金具12,…で連結した表側枠体8Aと裏側枠体8Bとからなっている。つまり、前記表側枠体8Aは、両側縦枠部材9A,9A、上横枠部材10A及び下横枠部材11Aを連結金具12で連結した構造である。また、前記裏側枠体8Bは、両側縦枠部材9B,9B、上横枠部材10B及び下横枠部材11Bを連結金具12で連結した構造である。ここで、上横枠部材10Aと下横枠部材11A及び上横枠部材10Bと下横枠部材11Bはそれぞれ同じ部材である。つまり、上横枠10と下横枠11は同一形状であり、上下反転して使用している。   More specifically, the frame body 8 includes both vertical frame members 9A and 9B, upper horizontal frame members 10A and 10B, and lower horizontal frame members 11A and 11B each made of an extruded aluminum material, and the connection fittings 12,.

前記連結金具12は、図5に示すように、L字状の連結板29の両固定部30,30の外側縁に補強板31をそれぞれ直角に折曲形成した形状である。本実施形態の連結金具12は、連結板29が同一平面上にあるものである。尚、前記連結金具12は、平板状のものでも良い。要は、前記連結金具12には、前記縦枠部材9Bと上横枠部材10B又は下横枠部材11Bとの連結部が、前記支柱5のロッキングに従って連結角度が変わるように変形することが要求される。   As shown in FIG. 5, the connection fitting 12 has a shape in which reinforcing plates 31 are bent at right angles on the outer edges of both fixing portions 30, 30 of an L-shaped connection plate 29. In the connection fitting 12 of this embodiment, the connection plate 29 is on the same plane. The connecting metal fitting 12 may be a flat plate. In short, the connecting bracket 12 is required to deform the connecting portion between the vertical frame member 9 </ b> B and the upper horizontal frame member 10 </ b> B or the lower horizontal frame member 11 </ b> B so that the connection angle changes according to the locking of the support column 5. Is done.
前記両側縦枠部材9A,9B、上横枠部材10A,10B及び下横枠部材11A,11Bは、端部をそれぞれ45度に切断し、切断縁を接合することによって各部材が90度の角度で連結できるようにしているが、切断角度は45度に限定されない。前記縦枠部材9A,9A、上横枠部材10A及び下横枠部材11Aの端部に、それぞれ前記連結金具12の固定部30と補強板31を挿入し、該固定部30を前記保持板20の基部外側面に接合状態でネジ32,…で連結して、前記表側枠体8Aを形成する。同様に、前記縦枠部材9B,9B、上横枠部材10B及び下横枠部材11Bの端部に、それぞれ前記連結金具12の固定部30と補強板31を挿入し、該固定部30を前記保持板24の基部外側面に接合状態で、ネジ33,…で連結して、前記裏側枠体8Bを形成する。   Each of the vertical frame members 9A and 9B, the upper horizontal frame members 10A and 10B, and the lower horizontal frame members 11A and 11B is cut at an end of 45 degrees, and the cut edges are joined to form an angle of 90 degrees. However, the cutting angle is not limited to 45 degrees. The fixing portion 30 and the reinforcing plate 31 of the connecting metal fitting 12 are inserted into the end portions of the vertical frame members 9A, 9A, the upper horizontal frame member 10A, and the lower horizontal frame member 11A, respectively. The base side frame 8A is formed by connecting to the outer surface of the base portion with screws 32,. Similarly, the fixing portion 30 and the reinforcing plate 31 of the coupling metal 12 are inserted into the end portions of the vertical frame members 9B and 9B, the upper horizontal frame member 10B, and the lower horizontal frame member 11B, respectively. The back side frame 8B is formed by joining to the outer surface of the base portion of the holding plate 24 with screws 33,.
そして、前記表側枠体8Aを両支柱5,5間に表側から装着し、下横枠部材11Aの基板21の上に沿って敷設した弾性材19の上に前記ガラス板7を載支し、それから前記裏側枠体8Bを両支柱5,5間に裏側から装着して前記基板21と底面板25を重合するとともに、前記表側枠体8Aの保持板20と前記裏側枠体8Bの保持板24とで前記ガラス板7の周縁部を挟み込んだ状態で、前記取付板26と基板21をネジ34で連結して枠体8を構成する。この際に、前記支柱5の側面板が存在する側の縦枠9は、前記ネジ34で前記取付板26と基板21を連結すると同時に、前記支柱5に螺着し、該支柱5と縦枠9を一体化する。一方、反対側に前記支柱5の開口溝を有する側の縦枠9は支柱5に固定されない。   The front frame 8A is mounted from the front side between the support columns 5 and 5, and the glass plate 7 is placed on the elastic member 19 laid along the substrate 21 of the lower horizontal frame member 11A. Then, the back frame 8B is mounted between the columns 5 and 5 from the back to superimpose the substrate 21 and the bottom plate 25, and the holding plate 20 of the front frame 8A and the holding plate 24 of the back frame 8B. The frame 8 is configured by connecting the mounting plate 26 and the substrate 21 with screws 34 in a state where the peripheral edge of the glass plate 7 is sandwiched between the mounting plate 26 and the substrate 21. At this time, the vertical frame 9 on the side where the side plate of the column 5 exists is connected to the mounting plate 26 and the substrate 21 with the screw 34 and simultaneously screwed to the column 5, and the column 5 and the vertical frame are connected. 9 is integrated. On the other hand, the vertical frame 9 on the side having the opening groove of the column 5 on the opposite side is not fixed to the column 5.
前記枠体8でガラス板7を挟み込んで両側支柱5,5間に取付けた状態では、前記包持部23,28で天レール3と地レール4を表裏両側から包持する。また、前記下横枠11は、図6に示すように、前記サブアジャスター16で下横枠部材11Aの基板21を載支し、前記ガラスパネル6の荷重を受け、該下横枠11の撓みを防止している。   In a state where the glass plate 7 is sandwiched between the frame bodies 8 and attached between the both side columns 5, 5, the top rail 3 and the ground rail 4 are gripped from the front and back sides by the gripping portions 23, 28.

In this case, if the joint portions of the vertical frame 9 and the upper horizontal frame 10 and the lower horizontal frame 11 are in close contact with each other, the members are pressed against each other and the deformation amount is suppressed. If a gap is provided in the joint, there is no problem in the deformation of the frame body 8. In addition, the said clearance gap can be concealed by sticking the seal | sticker of the same color on a connection part, and an external appearance is not affected.
次に、図8〜図11に基づいて、本発明の第2実施形態に係る高耐震性ガラスパネル装置を説明する。本実施形態においても、ガラス板7を保持する枠体8を表側枠体8Aと裏側枠体8Bとで構成し、使用する縦枠部材9A,9B、上横枠部材10A,10B及び下横枠部材11A,11Bも第1実施形態と同一型材である。但し、前記縦枠部材9A,9B、上横枠部材10A,10B及び下横枠部材11A,11Bの各部材の端部は、図10に示すように、前記保持板20,24と嵌合部22,27あるいは包持部23,28の部分で、90度の角度で階段状に切断している。   Next, based on FIGS. 8-11, the highly earthquake-resistant glass panel apparatus which concerns on 2nd Embodiment of this invention is demonstrated. Also in the present embodiment, the frame body 8 that holds the glass plate 7 is composed of the front side frame body 8A and the back side frame body 8B, and the vertical frame members 9A and 9B, the upper horizontal frame members 10A and 10B, and the lower horizontal frame that are used. The members 11A and 11B are also the same mold material as the first embodiment. However, as shown in FIG. 10, the end portions of the vertical frame members 9A and 9B, the upper horizontal frame members 10A and 10B, and the lower horizontal frame members 11A and 11B are fitted with the holding plates 20 and 24, respectively. 22 and 27 or the holding portions 23 and 28 are cut stepwise at an angle of 90 degrees.
本実施形態の連結金具12Aは、図11に示すように、短冊状の連結板35を中心で直角に屈曲して屈曲部の両側に連結片36,36を形成し、該連結片36,36の一側縁に直角に固定板37,37を折曲形成した形状である。ここで、屈曲線を連結板35の板面に沿って形成しているので、該屈曲部の部分で両連結片36,36が変形し易くなっている。   As shown in FIG. 11, the connection fitting 12 </ b> A of the present embodiment is bent at a right angle around a strip-shaped connection plate 35 to form connection pieces 36, 36 on both sides of the bent portion, and the connection pieces 36, 36. The fixed plates 37, 37 are bent at right angles to one side edge. Here, since the bending line is formed along the plate surface of the connecting plate 35, both connecting pieces 36, 36 are easily deformed at the bent portion.
前記連結金具12Aを用いて前記縦枠部材9A,9A、上横枠部材10A及び下横枠部材11Aの端部を接合状態で連結して表側枠体8Aを構成する点は前記同様である。また、前記連結金具12Aの固定板37は、前記連結金具12の固定部30に対応し、前記連結金具12Aの連結片36は、前記連結金具12の補強板31に対応し、それぞれ前記同様にネジ32で各部材を連結して表側枠体8Aを構成する。同様に、前記連結金具12Aを用いて前記縦枠部材9B,9B、上横枠部材10B及び下横枠部材11Bの端部を接合状態で連結して裏側枠体8Bを構成する。それから,表側枠体8Aと裏側枠体8Bとでガラス板7を挟み込んで前記両側の支柱5,5間に天レール3と地レール4に関連付けて装着する手順も前記同様である。   The front frame member 8A is configured in the same manner as described above by connecting the ends of the vertical frame members 9A, 9A, the upper horizontal frame member 10A, and the lower horizontal frame member 11A in a joined state using the connecting metal 12A. Further, the fixing plate 37 of the connecting fitting 12A corresponds to the fixing portion 30 of the connecting fitting 12, and the connecting piece 36 of the connecting fitting 12A corresponds to the reinforcing plate 31 of the connecting fitting 12, respectively. Each member is connected with a screw 32 to constitute the front side frame 8A. Similarly, the back frame 8B is configured by connecting the end portions of the vertical frame members 9B, 9B, the upper horizontal frame member 10B, and the lower horizontal frame member 11B in a joined state using the connection fitting 12A. The procedure for attaching the glass plate 7 between the front side frame 8A and the back side frame 8B in association with the top rail 3 and the ground rail 4 between the columns 5 and 5 on both sides is the same as described above.
本実施形態の場合も、図9(b)のように、地震時の層間変位によって支柱5が傾斜すると、前記枠体8の縦枠9と上横枠10の連結部及び縦枠9と下横枠11の連結部が、前記連結金具12Aが変形することにより屈曲し、全体として平行四辺形の状態に変形する。このように枠体8が変形しても、ガラス板7の周縁部は枠体8の保持溝13で保持された状態を維持するのである。   Also in this embodiment, as shown in FIG. 9B, when the support column 5 is inclined due to the interlayer displacement at the time of the earthquake, the connecting portion of the vertical frame 9 and the upper horizontal frame 10 of the frame body 8 and the vertical frame 9 and the lower frame The connecting portion of the horizontal frame 11 is bent by the deformation of the connecting fitting 12A, and is deformed into a parallelogram as a whole. Thus, even if the frame body 8 is deformed, the peripheral edge portion of the glass plate 7 is maintained in the state of being held by the holding groove 13 of the frame body 8.
