Abstract

<P>PROBLEM TO BE SOLVED: To provide a glass wall construction etc. which are constructed such that shearing force occurring at the time of an earthquake or the like is borne by a glass sheet. <P>SOLUTION: According to the glass wall construction, support members 2, 3 supporting upper and lower edges of the glass sheet 1 for use as a structural member bearing compressive force and shearing force, are formed of steel products or the like, and the upper and lower edges of the glass sheet are supported by the support members arranged in layers defined by upper and lower structural members 8, 11 and the glass sheet per se, respectively. The upper and lower edges of the glass sheet are brought into surface contact with the support members so as to uniformly transfer the compressive force and the shearing force from the support members to the entire surface of the glass sheet. The upper support member is connected to the upper structural member via a member 9 which does not transfer tensile force from the upper structural member but transfers the compressive force and the shearing force within a safety factor. Further, one end of the transfer member is connected to either the upper support member or the upper structural member, while the other end of the same is fitted into a mortise 10 formed in the other members. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

本発明は、板ガラスを壁状の構造部材として用いたガラス壁構造体と、柱ガラスを柱状の構造部材として用いたガラス柱構造体の技術分野に属し、更に云うと、地震時などに生じるせん断力（以下、単にせん断力という場合がある。）を板ガラスに負担させる構成としたガラス壁構造体と、建築物の重量による圧縮力（以下、単に圧縮力という場合がある。）を柱ガラスに負担させる構成としたガラス柱構造体に関する。 The present invention belongs to the technical field of a glass wall structure using plate glass as a wall-shaped structural member, and a glass column structure using column glass as a column-shaped structural member. A glass wall structure configured to load a sheet glass with a force (hereinafter sometimes referred to simply as a shearing force) and a compressive force (hereinafter also referred to simply as a compressive force) due to the weight of the building to the column glass. The present invention relates to a glass column structure configured to bear.

（Ａ）最近、建築物のデザイン性を向上させるために、板ガラスを建築材料として用いた建築物を多く見ることができる。しかし、板ガラスは、構造部材としては用いられておらず、板ガラスと支持材（主に、周辺枠フレーム）との間に（１）クリアランスを設けたり、（２）緩衝材を入れたりして、板ガラスに大きな外力（主に、圧縮力及びせん断力）が伝達されない構成のガラス壁構造体とされ、板ガラスに圧縮力及びせん断力を負担させる技術的思想ではない。 (A) Recently, many buildings using plate glass as building materials can be seen in order to improve the design of buildings. However, the plate glass is not used as a structural member, and (1) clearance is provided between the plate glass and the support material (mainly the peripheral frame frame), or (2) a cushioning material is inserted. The glass wall structure has a structure in which a large external force (mainly compression force and shear force) is not transmitted to the plate glass, and is not a technical idea that bears the compression force and shear force on the plate glass.

上記（１）のガラス壁構造体としては、例えば、以下の技術が公知である。
非特許文献１のガラス壁構造体は、板ガラスが周辺枠フレームとクリアランスを設けて配置され、その下端部がクロロプレンゴム製のセッティングブロックで支持されており、周辺枠フレームから板ガラスに圧縮力及びせん断力が伝達されない構造とされている。 As the glass wall structure (1), for example, the following techniques are known.
In the glass wall structure of Non-Patent Document 1, a plate glass is disposed with a clearance with a peripheral frame frame, and a lower end portion of the glass wall structure is supported by a setting block made of chloroprene rubber. The structure is such that no force is transmitted.

上記（２）のガラス壁構造体としては、例えば、以下の技術が公知である。
（ｉ）特許文献１のガラス壁構造体は、板ガラスの外周が、溝内に粘性体を収容した周辺枠フレームに嵌め込まれ支持されており、周辺枠フレームから板ガラスに圧縮力及びせん断力が伝達されず、地震等による水平変位が生じた場合に、板ガラスが周辺枠フレームに対して面内方向へ相対移動して減衰作用を発揮する構造とされている。 As the glass wall structure (2), for example, the following techniques are known.
(I) In the glass wall structure of Patent Document 1, the outer periphery of the plate glass is fitted and supported by a peripheral frame frame containing a viscous material in a groove, and compression force and shear force are transmitted from the peripheral frame frame to the plate glass. However, when horizontal displacement due to an earthquake or the like occurs, the plate glass moves relative to the peripheral frame frame in the in-plane direction and exhibits a damping action.

（ii）特許文献２のガラス壁構造体は、板ガラスの外周が、弾性シール材を介して周辺枠フレームで支持されており、周辺枠フレームから板ガラスに圧縮力及びせん断力が伝達されない構造とされている。前記板ガラスは強化ガラスで構成され、防犯性が高められている。また、前記板ガラスのエッジが面取され、該エッジに応力が集中することを防ぎ、板ガラスの破損が防止されている。 (Ii) The glass wall structure of Patent Document 2 has a structure in which the outer periphery of the plate glass is supported by the peripheral frame frame via an elastic sealing material, and compression force and shear force are not transmitted from the peripheral frame frame to the plate glass. ing. The said plate glass is comprised with the tempered glass and the crime prevention property is improved. Moreover, the edge of the said plate glass is chamfered, it prevents that stress concentrates on this edge, and the failure | damage of a plate glass is prevented.

（Ｂ）建築物の柱としてガラス柱構造体を用いて、圧縮力を負担させる技術は見聞できない。
旭硝子カタログ第３７頁の施工図、第４３頁の施工図特開２００１−１９３３５７号公報特開２０００−２０３８９５号公報 (B) The technology of using a glass column structure as a building pillar to bear the compressive force cannot be heard.

ガラスは、フロートガラスで１０００N/mm²を超える圧縮強度を有すると云われている。従来の上記（１）及び（２）のガラス壁構造体は、この圧縮強度を有効に発揮させて、圧縮力及びせん断力を負担させる構造とされていない。そのため、採光を必要とする建築物の開口部における架構では、構造上の耐力や剛性が不足するため、開口部以外の部分に耐震壁を設けたり、柱や梁部材の断面を大きくしたりするなど、構造設計上の制約がある。 The glass is said to have a compressive strength of more than 1000 N / mm ² with float glass. The conventional glass wall structures of the above (1) and (2) are not configured to effectively exert this compressive strength and bear compressive force and shear force. For this reason, the structural strength and rigidity of the frame in the opening of buildings that require lighting are insufficient, so a seismic wall is provided in areas other than the opening, and the cross sections of columns and beam members are enlarged. There are restrictions on structural design.

仮に、板ガラスと周辺枠フレームとを単に剛強に接合した程度では、地震時に面内方向にせん断変形した周辺枠フレームが板ガラスと部分的に接触し、その接触部分から局部的にせん断力が伝達され、同板ガラスが破損する可能性がある。 Assuming that the plate glass and the peripheral frame frame are simply rigidly joined, the peripheral frame frame that has undergone shear deformation in the in-plane direction during an earthquake partially contacts the plate glass, and shear force is transmitted locally from the contact portion. The glass sheet may be damaged.

上述したように、建築物の柱としてガラス柱構造体を用いる技術は見聞できない。通例は、建築意匠のデザイン上、見栄えが悪い柱が視野に入り、やはり構造設計上の制約がある。 As described above, the technology using a glass column structure as a building column cannot be seen. As usual, there is a structural design constraint because of poor visual appearance in architectural design.

本発明の目的は、ガラスが本来有する大きな圧縮強度を発揮させて、地震時などに生じるせん断力を負担させることによって、建築物の開口部における架構の耐力や剛性を確保し、耐震壁を省略したり、柱や梁部材の断面を小さくでき、構造設計上の制約を軽減することができるガラス壁構造体を提供することである。 The purpose of the present invention is to ensure the strength and rigidity of the frame at the opening of the building by demonstrating the large compressive strength inherent in glass and bearing the shearing force that occurs during earthquakes, etc., and omit the earthquake resistant wall It is to provide a glass wall structure that can reduce the cross-section of pillars and beam members and reduce structural design constraints.

本発明の目的は、ガラスが本来有する大きな圧縮強度を発揮させて、建築物の重量による圧縮力を負担させることによって、建築意匠のデザイン上、見栄えの悪い柱がほとんど視野に入らず、構造設計上の制約を軽減することができるガラス柱構造体を提供することである。 The purpose of the present invention is to show the large compressive strength inherent in glass and to bear the compressive force due to the weight of the building, so that the design of the architectural design has almost no unsightly pillars in view, and the structural design It is to provide a glass column structure that can alleviate the above constraints.

本発明に係るガラス壁構造体は、板ガラスが本来有する圧縮強度を発揮させ、且つせん断力を負担させるので、建築物の開口部における架構の耐力や剛性を確保し、建築意匠のデザイン上、見栄えが悪い柱や梁部材の断面を小さくすることができる。また、鉄筋コンクリート耐震壁やブレース等を可及的に省略することができ、構造設計上の自由度が増す。 The glass wall structure according to the present invention exerts the compressive strength inherent in the plate glass and bears the shearing force, thus ensuring the strength and rigidity of the frame in the opening of the building, and the appearance of the design of the architectural design. However, the cross section of a bad column or beam member can be reduced. In addition, reinforced concrete shear walls and braces can be omitted as much as possible, increasing the degree of freedom in structural design.

特に、請求項１に記載した発明に係るガラス壁構造体は、建築物の重量による圧縮力を負担させるので、更に、構造設計上の自由度が増す。 In particular, since the glass wall structure according to the first aspect of the present invention bears a compressive force due to the weight of the building, the degree of freedom in structural design is further increased.

上側支持材は、上部構造材又は上側フレーム材からの引張力を伝達せず、しかも設定された安全率以内の圧縮力及びせん断力を伝達する部材を介して上部構造材又は上側フレーム材と連結されているので、板ガラスが破損することがなく、構造上の信頼性が高い。 The upper support material does not transmit the tensile force from the upper structural material or the upper frame material, and is connected to the upper structural material or the upper frame material via a member that transmits the compressive force and shear force within the set safety factor. Therefore, the plate glass is not damaged and the structural reliability is high.

次に、本発明に係るガラス柱構造体は、柱ガラスが本来有する圧縮強度を発揮させ建築物の重量（圧縮力）を負担させる建築物の柱として用いるので、ガラス固有の透明感のある空間を創り出すことができ、建築意匠のデザイン上、見栄えを悪くする柱がほとんど視野に入らず、構造設計上の自由度が増す。 Next, since the glass columnar structure according to the present invention is used as a column of a building that exhibits the compressive strength inherent in the columnar glass and bears the weight (compression force) of the building, a transparent space unique to glass. As the design of the architectural design, the pillars that make it look bad are hardly in view, and the degree of freedom in structural design increases.

積層ゴム等で構成された上側支持材は、上部構造材からの圧縮力を伝達するように上部構造材と接触され、引張力は伝達させず、せん断力は上側支持材が略吸収するように相互に連結されているので、柱ガラスが破損することがなく、構造上の信頼性が高い。 The upper support material composed of laminated rubber or the like is brought into contact with the upper structure material so as to transmit the compressive force from the upper structure material, the tensile force is not transmitted, and the shear force is substantially absorbed by the upper support material. Since they are connected to each other, the column glass is not damaged, and the structural reliability is high.

先ず、請求項１及び請求項３〜請求項６に記載した発明に係るガラス壁構造体の実施形態を、図１〜図６に基づいて説明する。 First, an embodiment of a glass wall structure according to the invention described in claim 1 and claims 3 to 6 will be described with reference to FIGS. 1 to 6.

図１に示すガラス壁構造体は、板ガラス１に建築物の重量による圧縮力及び地震時などに生じるせん断力を負担させ、構造部材として用いる構成であり、同板ガラス１の上縁１ａ及び下縁１ｂを支持する上下の支持材２、３は鋼材等で構成されている。前記板ガラス１の両側面には、該板ガラス１を補剛する補剛用板ガラス４が貼り合わされ、３枚の合わせ板ガラス５として構成されている（図１を参照、請求項３記載の発明）。各板ガラス１、４の上縁１ａと４ａ及び下縁１ｂと４ｂはダイヤモンドカッター等で切断され、通常のガラスの製造で用いられる程度の研磨を行った粗さで水平面とされている。なお、前記補剛用板ガラス４には、圧縮力及びせん断力が伝達されないように、上下の端縁は緩衝材６を介して支持材２、３に嵌め込まれている。そのため、緩衝材６の厚み分だけ中央の板ガラス１の高さＨより低く切断されている。前記補剛用板ガラス４の外側面における上下の支持材２と３の間の露出部に、面外方向に対する風圧などに対処するための座屈補剛用方立てガラス７が設けられている。方立てガラス７の上縁と上側支持材２の鉛直部２ｂ、及び下縁と下側支持材３の鉛直部３ｂとの間には、圧縮力及びせん断力が伝達されないようにクリアランスＴが設けられている（請求項４記載の発明）。 The glass wall structure shown in FIG. 1 has a configuration in which a sheet glass 1 is subjected to a compressive force due to the weight of a building and a shearing force generated during an earthquake and used as a structural member. The upper and lower support members 2 and 3 that support 1b are made of steel or the like. A stiffening plate glass 4 for stiffening the plate glass 1 is bonded to both side surfaces of the plate glass 1 to form three laminated plate glasses 5 (see FIG. 1, invention according to claim 3). The upper edges 1a and 4a and the lower edges 1b and 4b of each plate glass 1 and 4 are cut with a diamond cutter or the like, and are made to have a horizontal surface with a roughness that is polished to the extent used in ordinary glass production. In addition, the upper and lower end edges of the stiffening plate glass 4 are fitted to the support members 2 and 3 via the cushioning material 6 so that the compressive force and the shearing force are not transmitted. Therefore, it is cut below the height H of the central plate glass 1 by the thickness of the buffer material 6. A buckled stiffening vertical glass 7 is provided at an exposed portion between the upper and lower supporting members 2 and 3 on the outer surface of the stiffening plate glass 4 to cope with wind pressure in the out-of-plane direction. A clearance T is provided between the upper edge of the vertical glass 7 and the vertical portion 2b of the upper support member 2 and between the lower edge and the vertical portion 3b of the lower support member 3 so that compressive force and shear force are not transmitted. (Invention of claim 4).

上下の支持材２、３はコ字断面形状とされており、各支持材２、３の水平部２ａ、３ａは、圧縮力及びせん断力が伝達された際に、同圧縮力及びせん断力が板ガラスに均等に作用するように十分な厚さを有する普通鋼材（ＳＳ４００）で構成されている。前記水平部２ａ、３ａの両端部から鉛直に立ち上がり、合わせ板ガラス５の上部又は下部を挟んで支持する鉛直部２ｂ、３ｂは、支持材２、３の製作容易性を考慮して、水平部２ａ、３ａと同様に普通鋼材で構成されている。 The upper and lower support members 2 and 3 have a U-shaped cross section, and the horizontal portions 2a and 3a of the support members 2 and 3 receive the same compressive force and shear force when the compressive force and shear force are transmitted. It is made of ordinary steel material (SS400) having a sufficient thickness so as to act evenly on the plate glass. The vertical portions 2b and 3b, which stand vertically from both ends of the horizontal portions 2a and 3a and support the laminated plate glass 5 with the upper or lower portion sandwiched therebetween, are considered in consideration of the ease of manufacturing the supporting materials 2 and 3. Like 3a, it is made of ordinary steel.

上下の支持材２、３に、合わせ板ガラス５の上縁及び下縁が共通に嵌め込まれ支持されている。具体的には、図１に示すように、板ガラス１が直接に支持材２、３に嵌め込まれ支持されている（請求項３記載の発明）。その結果、板ガラス１の上縁１ａは、全面が直接に上側支持材２の水平部２ａの下面と密着状態に面接触されている。同板ガラス１の下縁１ｂも、全面が直接に下側支持材３の水平部３ａの上面と密着状態に面接触され、もって支持材２、３から板ガラス１に圧縮力及びせん断力が全面略一様の分布に（均等に分配して）伝達される構造とされている。上下の支持材２、３は、伝達される圧縮力及びせん断力によって塑性変形しないので、前記上側支持材２の水平部２ａと板ガラス１の上縁１ａ、及び下側支持材３の水平部３ａと板ガラス１の下縁１ｂは面接触状態を維持し、通常時には圧縮力を均等に分配して板ガラス１に伝達する。地震時にも、図３に示すように圧縮力を均等に分配して板ガラス１に伝達すると共に、該圧縮力によって上側支持材２の水平部２ａと板ガラス１の上縁１ａ、及び下側支持材３の水平部３ａと板ガラス１の下縁１ｂを圧着させたまま、せん断力を均等に分配して板ガラス１に伝達する。そのため板ガラス１に局部的な応力集中が生じて破損することがなく、板ガラス１が本来有する圧縮強度を十分に発揮させて、圧縮力及びせん断力を負担させることができる。 The upper and lower edges of the laminated glass sheet 5 are fitted and supported in common on the upper and lower supports 2 and 3. Specifically, as shown in FIG. 1, the plate glass 1 is directly fitted into and supported by the support members 2 and 3 (the invention according to claim 3). As a result, the entire upper edge 1a of the plate glass 1 is in direct surface contact with the lower surface of the horizontal portion 2a of the upper support member 2 in close contact. The lower edge 1b of the glass sheet 1 is also brought into direct contact with the upper surface of the horizontal portion 3a of the lower support material 3 in close contact with each other, so that the compressive force and shearing force from the support materials 2 and 3 to the glass sheet 1 are substantially all over. It is structured to be transmitted in a uniform distribution (evenly distributed). Since the upper and lower support members 2 and 3 are not plastically deformed by the transmitted compressive force and shear force, the horizontal portion 2 a of the upper support member 2, the upper edge 1 a of the glass sheet 1, and the horizontal portion 3 a of the lower support member 3. The lower edge 1b of the glass plate 1 maintains a surface contact state, and normally, the compressive force is evenly distributed and transmitted to the glass plate 1. Even during an earthquake, as shown in FIG. 3, the compressive force is evenly distributed and transmitted to the plate glass 1, and the horizontal portion 2a of the upper support member 2, the upper edge 1a of the plate glass 1, and the lower support member are transmitted by the compressive force. 3, the shearing force is evenly distributed and transmitted to the plate glass 1 while the horizontal portion 3 a of the plate 3 and the lower edge 1 b of the plate glass 1 are pressed. Therefore, local stress concentration does not occur in the glass plate 1 and it is not damaged, and the compressive strength and shearing force can be borne by fully exerting the compressive strength inherent to the glass plate 1.

補剛用板ガラス４は、上下に圧縮力及びせん断力を伝達しない緩衝材６を介して支持材２、３に嵌め込まれ支持されている（請求項３記載の発明）。よって、支持材２、３から補剛用板ガラス４に圧縮力及びせん断力が伝達されない。 The stiffening plate glass 4 is fitted into and supported by the support materials 2 and 3 via a cushioning material 6 that does not transmit compressive force and shear force vertically (invention of claim 3). Therefore, compressive force and shearing force are not transmitted from the support materials 2 and 3 to the stiffening plate glass 4.

ガラスは圧縮力に対して本来大きな圧縮強度を有するが、破損する場合には非常に脆性的な性状を有し、更に引張力に対しては非常に弱い性状を有する。そのため、適当な安全率を設定し、その安全率以内の圧縮力及びせん断力を板ガラス１に伝達でき、且つ有害な引張力を伝達しない支持構造とすることが肝要である。図１等に示したガラス壁構造体は、上側支持材２が、設定された安全率以内の圧縮力及びせん断力を伝達する部材９を介して上部構造材８と連結されている。具体的には、前記伝達部材９は、Ｈ形断面形状に形成された普通鋼材、低降伏点鋼材、極低降伏点鋼材、アルミニウム等で構成されている。そのウエブ部分が図４に示す性状を発揮し、フランジ部分が図５に示す性状を発揮するように設定されている。この伝達部材９はフランジ部分９ａが板ガラス１の外側面と直角となり、ウエブ部分９ｂが板ガラス１の外側面と平行となるように配置されており、下端が上側支持材２に固定され、上端が上部構造材８の下端部に形成されたほぞ穴１０に嵌め込まれている（図２を参照、請求項６記載の発明）。すなわち、伝達部材９とほぞ穴１０との嵌合部から圧縮力及びせん断力を板ガラス１に伝達するが、同圧縮力及びせん断力が安全率を超えると伝達部材９が破損し、過剰な圧縮力及びせん断力を伝達しない。また、伝達部材９がほぞ穴１０から抜け出して引張力を板ガラス１に伝達しない。そのため、板ガラス１に圧縮力及びせん断力を健全に負担させることができる。Ｈ形断面形状の伝達部材９は、繰り返し変形によりウエブ部分９ｂで図６に示すような履歴を有し、地震時の振動エネルギを吸収し、建築物全体の揺れを低減できる。 Glass inherently has a high compressive strength with respect to a compressive force, but has a very brittle property when broken, and has a very weak property with respect to a tensile force. Therefore, it is important to set an appropriate safety factor, and to have a support structure that can transmit the compression force and shear force within the safety factor to the glass sheet 1 and does not transmit harmful tensile force. In the glass wall structure shown in FIG. 1 and the like, the upper support member 2 is connected to the upper structure member 8 via a member 9 that transmits a compression force and a shear force within a set safety factor. Specifically, the transmission member 9 is made of a normal steel material, a low yield point steel material, an extremely low yield point steel material, aluminum, or the like formed in an H-shaped cross-sectional shape. The web portion is set to exhibit the properties shown in FIG. 4, and the flange portion is set to exhibit the properties shown in FIG. The transmission member 9 is arranged such that the flange portion 9a is perpendicular to the outer surface of the glass sheet 1, the web portion 9b is parallel to the outer surface of the glass sheet 1, the lower end is fixed to the upper support member 2, and the upper end is The upper structural member 8 is fitted in a mortise 10 formed in the lower end portion (see FIG. 2, invention of claim 6). That is, the compression force and shear force are transmitted to the glass sheet 1 from the fitting portion between the transmission member 9 and the mortise 10, but if the compression force and shear force exceed the safety factor, the transmission member 9 is damaged and excessive compression is performed. Does not transmit force and shear force. Further, the transmission member 9 comes out of the mortise 10 and does not transmit the tensile force to the glass sheet 1. Therefore, the plate glass 1 can be loaded with a compressive force and a shearing force. The transmission member 9 having an H-shaped cross-section has a history as shown in FIG. 6 at the web portion 9b by repeated deformation, absorbs vibration energy at the time of an earthquake, and can reduce shaking of the entire building.

下側支持材３は、合わせ板ガラス５を支持できるように下部構造材１１の上面に載置され剛強に連結されている。 The lower support member 3 is placed on the upper surface of the lower structural member 11 and is rigidly connected so that the laminated glass sheet 5 can be supported.

上記構成のガラス壁構造体は、板ガラス１が本来有する圧縮強度を発揮して、通常時に建築物の重量による圧縮力を負担する。また、地震時には、建築物の重量による圧縮力を負担しながら、せん断力も負担するから、建築物の開口部における架構の耐力や剛性を確保し、建築意匠のデザイン上、見栄えを悪くする柱や梁部材の断面を小さくすることができる。そして、鉄筋コンクリート耐震壁やブレース等を省略することができ、構造設計上の自由度が増す。 The glass wall structure having the above structure exhibits the compressive strength inherent to the plate glass 1 and bears the compressive force due to the weight of the building during normal times. Also, in the event of an earthquake, while bearing the compressive force due to the weight of the building, it also bears the shearing force. The cross section of the beam member can be reduced. And a reinforced concrete earthquake-resistant wall, a brace, etc. can be omitted, and the freedom degree in structural design increases.

しかも、板ガラス１に引張力を伝達せず、且つ安全率以内の圧縮力及びせん断力を伝達する構造とされているので、板ガラス１が破損することがなく、万一に破損したとしても、板ガラス１の両側の補剛用板ガラス４が圧縮力及びせん断力を負担するので、構造上の信頼性が高い。 In addition, since the tensile force is not transmitted to the plate glass 1 and the compression force and the shear force within the safety factor are transmitted, the plate glass 1 is not damaged, and even if it is damaged, the plate glass Since the stiffening glass plates 4 on both sides of 1 bear the compressive force and the shearing force, the structural reliability is high.

なお、本実施形態では、建築物の重量による圧縮力で板ガラス１の上縁１ａと上側支持材２、及び板ガラス１の下縁１ｂと下側支持材３とを圧着させた構造とされているが、この構造に限らない。図示は省略するが、上下の支持材２と３をＰＣ鋼材等で連結しプレストレスを導入することによって緊張し、圧着させた構造を実施すると更に良い（請求項５記載の発明）。 In addition, in this embodiment, it is set as the structure which pressure-bonded the upper edge 1a and the upper side support material 2 of the plate glass 1, and the lower edge 1b and the lower side support material 3 of the plate glass 1 with the compressive force by the weight of a building. However, it is not limited to this structure. Although not shown in the drawings, it is better to implement a structure in which the upper and lower support members 2 and 3 are connected by PC steel or the like and are tensioned and crimped by introducing pre-stress (invention of claim 5).

次に、請求項２及び請求項７に記載した発明に係るガラス壁構造体の実施形態を図７〜図９に基づいて説明する。なお、図１等に示したガラス壁構造体との共通部材には、同一の符号を使用し、詳細な説明は省略する。 Next, an embodiment of the glass wall structure according to the invention described in claim 2 and claim 7 will be described with reference to FIGS. In addition, the same code | symbol is used for a common member with the glass wall structure shown in FIG. 1 etc., and detailed description is abbreviate | omitted.

図７に示すガラス壁構造体は、図１等に示したガラス壁構造体と基本的な構造は略同一であるが、圧縮力を周辺枠フレーム１２に略負担させている。 The glass wall structure shown in FIG. 7 has substantially the same basic structure as the glass wall structure shown in FIG.

上部構造材８と下部構造材１１との層間に周辺枠フレーム１２が設けられている。前記周辺枠フレーム１２は、圧縮力を負担するのに十分な剛性を有し、その上側フレーム材１２ａと下側フレーム材１２ｂとはＰＣ鋼材等１３で連結しプレストレスを導入することによって緊張している。 A peripheral frame 12 is provided between the upper structural member 8 and the lower structural member 11. The peripheral frame frame 12 has sufficient rigidity to bear the compressive force, and the upper frame material 12a and the lower frame material 12b are connected by a PC steel material 13 or the like and are strained by introducing prestress. ing.

前記周辺枠フレーム１２の下側フレーム材１２ｂは、せん断力を負担する板ガラス１の下縁を支持する支持材とされ（図７を参照）、板ガラス１の上縁を支持する上側支持材１４と同じく鋼材等で構成されている。なお、前記上側支持材１４は、図１等に示した上側支持材２と略同様に、水平部１４ａとその両側から立ち上がる鉛直部１４ｂとで構成されているが、上側支持材１４は圧縮力を略負担しないので、それを考慮して強度を落としても良い。 The lower frame member 12b of the peripheral frame frame 12 is a support member that supports the lower edge of the plate glass 1 that bears a shearing force (see FIG. 7), and the upper support member 14 that supports the upper edge of the plate glass 1. Similarly, it is made of steel. The upper support member 14 is composed of a horizontal portion 14a and a vertical portion 14b rising from both sides thereof, similar to the upper support member 2 shown in FIG. Therefore, the strength may be reduced in consideration of this.

上側支持材１４及び下側フレーム材１２ｂに、合わせ板ガラス５の上縁及び下縁が嵌め込まれ支持されている。その結果、図１等に示したガラス壁構造体と略同様に、板ガラス１の上縁１ａは全面が直接に上側支持材１４の水平部１４ａの下面と密着状態に面接触されている。同板ガラス１の下縁１ｂも、全面が直接に下側フレーム材１２ｂの水平部１２ｃの上面と密着状態に面接触されている。そして、上下のフレーム材１２ａと１２ｂとの緊張力によって、せん断力を全面略一様の分布に（均等に分配して）伝達することができるように圧着された構造とされている。つまり、上下のフレーム材１２ａと１２ｂを緊張することで、前記上側支持材１４の水平部１４ａと板ガラス１の上縁１ａ、及び下側フレーム材１２ｂの水平部１２ｃと板ガラス１の下縁１ｂを面接触状態に維持し、図９に示すように地震時などに生じるせん断力を均等に分配して板ガラス１に伝達する。そのため、板ガラス１に応力集中が生じて破損することがなく、板ガラス１が本来有する圧縮強度を発揮させて、せん断力を負担させることができる。なお、補剛用板ガラス４は、図１等に示したガラス壁構造体と略同様に、せん断力が伝達されないように、上下に緩衝材６を介して支持されている（図７を参照）。 The upper edge and the lower edge of the laminated glass sheet 5 are fitted into and supported by the upper support member 14 and the lower frame member 12b. As a result, almost the same as the glass wall structure shown in FIG. 1 or the like, the entire upper edge 1a of the glass sheet 1 is directly in surface contact with the lower surface of the horizontal portion 14a of the upper support member 14 in close contact. The entire lower edge 1b of the glass plate 1 is also in surface contact with the upper surface of the horizontal portion 12c of the lower frame member 12b in close contact. And it is set as the structure crimped | bonded so that a shearing force could be transmitted to the substantially uniform distribution over the whole surface (evenly distributed) with the tension | tensile_strength of the upper-and-lower frame materials 12a and 12b. That is, by tensioning the upper and lower frame members 12a and 12b, the horizontal portion 14a of the upper support member 14 and the upper edge 1a of the plate glass 1, and the horizontal portion 12c of the lower frame member 12b and the lower edge 1b of the plate glass 1 are formed. Maintaining the surface contact state, as shown in FIG. 9, the shear force generated during an earthquake or the like is evenly distributed and transmitted to the glass sheet 1. Therefore, stress concentration is not generated in the glass sheet 1 and the glass sheet 1 is not damaged, and the compressive strength inherent in the glass sheet 1 can be exhibited and the shearing force can be borne. Note that the stiffening plate glass 4 is supported via cushioning material 6 up and down so that shearing force is not transmitted, as in the glass wall structure shown in FIG. 1 and the like (see FIG. 7). .

上側支持材１４は、上側フレーム材１２ａからの引張力を伝達せず、設定された安全率以内のせん断力を伝達する部材１５を介して上側フレーム材１２ａと連結されている。具体的には、前記伝達部材１５は、図１等に示した伝達部材９と略同様にＨ形断面形状に形成された普通鋼材、低降伏点鋼材、極低降伏点鋼材、アルミニウム等で構成されている。この伝達部材１５はフランジ部分１５ａが板ガラス１の外側面と直角となり、ウエブ部分１５ｂが板ガラス１の外側面と平行となるように配置されており、下端が上側支持材１４の上端部に固定され、上端が上側フレーム材１２ａの下端部に形成されたほぞ穴１６に嵌め込まれている（請求項７記載の発明）。すなわち、伝達部材１５とほぞ穴１６との嵌合部からせん断力を板ガラス１に伝達するが、同せん断力が安全率を超えると伝達部材１５が破損し、過剰なせん断力を伝達しない。また、伝達部材１５がほぞ穴１６から抜け出して板ガラス１に引張力を伝達しない。そのため、板ガラス１にせん断力を健全に負担させることができる。Ｈ形断面形状の伝達部材１５も、繰り返し変形によりウエブ部分１５ｂで図６に示すような履歴を有し、地震時の振動エネルギを吸収し、建築物全体の揺れを低減できる。なお、前記伝達部材１５には圧縮力を略負担させないので、図５に示す性状を備えていなくても良い。 The upper support member 14 is connected to the upper frame member 12a via a member 15 that does not transmit a tensile force from the upper frame member 12a but transmits a shearing force within a set safety factor. Specifically, the transmission member 15 is composed of ordinary steel material, low yield point steel material, ultra-low yield point steel material, aluminum, etc. formed in an H-shaped cross-sectional shape in substantially the same manner as the transmission member 9 shown in FIG. Has been. The transmission member 15 is arranged such that the flange portion 15 a is perpendicular to the outer surface of the glass sheet 1, and the web portion 15 b is parallel to the outer surface of the glass sheet 1, and the lower end is fixed to the upper end portion of the upper support member 14. The upper end is fitted into a mortise 16 formed in the lower end of the upper frame member 12a (the invention according to claim 7). That is, the shearing force is transmitted to the glass sheet 1 from the fitting portion between the transmitting member 15 and the mortise 16, but if the shearing force exceeds the safety factor, the transmitting member 15 is broken and the excessive shearing force is not transmitted. Further, the transmission member 15 does not pass through the mortise 16 and does not transmit a tensile force to the glass sheet 1. Therefore, it is possible to load the plate glass 1 with a shearing force. The transmission member 15 having an H-shaped cross-section also has a history as shown in FIG. 6 at the web portion 15b by repeated deformation, absorbs vibration energy during an earthquake, and can reduce shaking of the entire building. Since the transmission member 15 is not substantially burdened with a compressive force, it does not have to have the properties shown in FIG.

周辺枠フレーム１２の左右のフレーム材１２ｄ、１２ｅと板ガラス１の側縁との間には、同周辺枠フレーム１２と板ガラス１とのせん断変形を許容する大きさのクリアランスＳが設けられている（図８を参照）。 Between the left and right frame members 12d and 12e of the peripheral frame frame 12 and the side edges of the plate glass 1, a clearance S having a size that allows shear deformation between the peripheral frame frame 12 and the plate glass 1 is provided ( (See FIG. 8).

上記構成のガラス壁構造体は、板ガラス１が本来有する圧縮強度を発揮して、地震時などに生じるせん断力を負担し、建築物の開口部における架構の耐力や剛性を確保し、建築意匠のデザイン上、見栄えを悪くする柱や梁部材の断面を小さくすることができる。そして、鉄筋コンクリート耐震壁やブレース等を省略することができ、構造設計上の自由度が増す。 The glass wall structure having the above structure exhibits the compressive strength inherent to the plate glass 1, bears the shearing force generated during an earthquake, etc., secures the strength and rigidity of the frame at the opening of the building, It is possible to reduce the cross section of columns and beam members that are unsatisfactory in design. And a reinforced concrete earthquake-resistant wall, a brace, etc. can be omitted, and the freedom degree in structural design increases.

しかも、板ガラス１に引張力を伝達せず、且つ安全率以内のせん断力を伝達する構造とされているので、板ガラス１が破損することがなく、構造上の信頼性が高い。 And since it is set as the structure which does not transmit a tensile force to the plate glass 1, and transmits the shear force within a safety factor, the plate glass 1 is not damaged and the structural reliability is high.

なお、本実施形態では、周辺枠フレーム１２が圧縮力を略負担する構造とされているが、周辺枠フレーム１２及び板ガラス１が負担する構造とされても良い。 In this embodiment, the peripheral frame 12 is configured to bear the compressive force. However, the peripheral frame 12 and the glass plate 1 may be configured to support the compression.

次に、請求項８及び請求項９に記載した発明に係るガラス柱構造体の実施形態を、図１０及び図１１に基づいて説明する。 Next, an embodiment of the glass columnar structure according to the invention described in claims 8 and 9 will be described with reference to FIGS. 10 and 11.

図１０等に示すガラス柱構造体は、柱ガラス１７の上下の端縁を支持する支持材１８、１９が、柱ガラス１７に圧縮力のみを伝達し、せん断力は略吸収する積層ゴムで構成され、その上下のフランジ１８ａ、１８ｂ及び１９ａ、１９ｂは鋼板等で構成されている。柱ガラス１７は、内外に嵌め合わせた内側のガラス管２０と、その外側の補剛用ガラス管２１との二重構造とされている（請求項９記載の発明）。前記ガラス管２０と補剛用ガラス管２１は、相互の高さが等しくなるように、上縁２０ａ及び２１ａ、下縁２０ｂ及び２１ｂがダイヤモンドカッター等で切断され、通常のガラスの製造で用いられる程度の研磨を行った粗さで水平面とされている。 The glass columnar structure shown in FIG. 10 and the like is composed of laminated rubber in which the support members 18 and 19 that support the upper and lower edges of the columnar glass 17 transmit only the compression force to the columnar glass 17 and substantially absorb the shearing force. The upper and lower flanges 18a, 18b and 19a, 19b are made of steel plates or the like. The column glass 17 has a double structure of an inner glass tube 20 fitted inside and outside and an outer stiffening glass tube 21 (the invention according to claim 9). The glass tube 20 and the stiffening glass tube 21 have upper edges 20a and 21a and lower edges 20b and 21b cut with a diamond cutter or the like so that their heights are equal to each other. It is assumed that the surface is level after being polished to a certain degree.

上下の支持材１８、１９は、通例の積層ゴムと同様にゴム板と鋼板とを積層した構成とされ、その上下のフランジ１８ａ、１８ｂ及び１９ａ、１９ｂは、圧縮力及びせん断力が伝達された際に、変形しないように十分な厚さを有する普通鋼板で構成されている。 The upper and lower support members 18 and 19 are configured by laminating rubber plates and steel plates in the same manner as usual laminated rubber. The upper and lower flanges 18a, 18b and 19a, 19b are transmitted with compressive force and shear force. In this case, it is made of a normal steel plate having a sufficient thickness so as not to be deformed.

上側支持材１８の下フランジ１８ｂに柱ガラス１７の上縁が固定され、下側支持材１９の上フランジ１９ａに柱ガラス１７の下縁が固定され支持されている。具体的には、前記ガラス管２０の上縁２０ａ及び補剛用ガラス管２１の上縁２１ａは、上側支持材１８の下フランジ１８ｂと接着剤等で接着（固定）され、下縁２０ｂと２１ｂは、下側支持材１９の上フランジ１９ａと同じく接着剤等で接着（固定）されている。その結果、ガラス管２０の上縁２０ａ及び補剛用ガラス管２１の上縁２１ａは全面が上側支持材１８の下フランジ１８ｂと密着状態に面接触されている。ガラス管２０の下縁２０ｂ及び補剛用ガラス管２１の下縁２１ｂも全面が下側支持材１９の上フランジ１９ａと密着状態に面接触されている。 The upper edge of the column glass 17 is fixed to the lower flange 18 b of the upper support member 18, and the lower edge of the column glass 17 is fixed to and supported by the upper flange 19 a of the lower support member 19. Specifically, the upper edge 20a of the glass tube 20 and the upper edge 21a of the stiffening glass tube 21 are bonded (fixed) to the lower flange 18b of the upper support member 18 with an adhesive or the like, and the lower edges 20b and 21b. Are bonded (fixed) with an adhesive or the like in the same manner as the upper flange 19a of the lower support member 19. As a result, the entire upper edge 20a of the glass tube 20 and the upper edge 21a of the stiffening glass tube 21 are in surface contact with the lower flange 18b of the upper support 18 in close contact. The lower edge 20b of the glass tube 20 and the lower edge 21b of the stiffening glass tube 21 are also in surface contact with the upper flange 19a of the lower support member 19 in close contact.

上側支持材１８の上フランジ１８ａは、上部構造材８からの圧縮力を伝達できるように、同上部構造材８の下面と面接触されている。そして、引張力を伝達せず、せん断力は上側支持材１８に略吸収させるように、上記上フランジ１８ａに複数本のダボピン２２…の下端が固定され、上端が上部構造材８に形成されたダボ穴２３に嵌め込まれ相互が連結されている。一方、下側の支持材１９の下フランジ１９ｂは、柱ガラス１７を支持できるように下部構造材１１の上面と剛強に連結されている。支持材１８、１９に伝達されたせん断力は、該支持材１８、１９の水平変位によって略吸収され、ガラス管２０と補剛用ガラス管２１には略伝達しない。圧縮力は、密着状態に面接触されたガラス管２０と補剛用ガラス管２１に均一に分配して伝達する。ガラスに有害な引張力は、ダボピン２２がダボ穴２３から抜け出して伝達しない構造とされている。 The upper flange 18a of the upper support member 18 is in surface contact with the lower surface of the upper structural member 8 so that the compressive force from the upper structural member 8 can be transmitted. The lower ends of the plurality of dowel pins 22 are fixed to the upper flange 18a and the upper ends are formed on the upper structural member 8 so that the upper support member 18 can absorb the tensile force without transmitting the tensile force. The dowel holes 23 are fitted and connected to each other. On the other hand, the lower flange 19b of the lower support member 19 is rigidly connected to the upper surface of the lower structural member 11 so that the column glass 17 can be supported. The shearing force transmitted to the support members 18 and 19 is substantially absorbed by the horizontal displacement of the support members 18 and 19 and is not substantially transmitted to the glass tube 20 and the stiffening glass tube 21. The compressive force is uniformly distributed and transmitted to the glass tube 20 and the stiffening glass tube 21 in surface contact in close contact. Tensile force harmful to the glass is structured to prevent the dowel pin 22 from being transmitted through the dowel hole 23.

上記構成のガラス柱構造体は、柱ガラス１７が本来有する圧縮強度を発揮させ建築物の重量による圧縮力を負担させる建築物の柱として用いるので、ガラス固有の透明感のある空間を創り出すことができ、建築意匠のデザイン上、見栄えを悪くする柱がほとんど視野に入らず、構造設計上の自由度が増す。 Since the glass column structure having the above-described structure is used as a pillar of a building that exhibits the compressive strength inherent to the column glass 17 and bears the compressive force due to the weight of the building, it is possible to create a transparent space unique to glass. Yes, there is almost no column that makes the appearance worse in the design of the architectural design, and the degree of freedom in structural design increases.

また、ダボピンを介して上側支持材１８と上部構造材８が連結されているので柱ガラス１７に引張力を伝達せず、且つ、前記上側支持材１８が積層ゴムで構成されせん断力を略伝達しない構造とされているので、柱ガラス１７が破損することがなく、構造上の信頼性が高い。
更に、上下の支持材１８、１９が地震時にせん断変形して制震効果を発揮する。 Further, since the upper support member 18 and the upper structural member 8 are connected via a dowel pin, the tensile force is not transmitted to the column glass 17, and the upper support member 18 is made of laminated rubber and substantially transmits the shear force. Therefore, the column glass 17 is not damaged, and the structural reliability is high.
Furthermore, the upper and lower support members 18 and 19 are shear-deformed at the time of an earthquake and exhibit a damping effect.

なお、本実施形態では、柱ガラス１７がガラス管２０と２１の二重構造とされているが、該ガラス管２０の内側に補剛用ガラス管を設けた三重構造でも良く、要するにガラス管２０を補剛することができれば、嵌め合わせるガラス管の数は特に限定されない。 In this embodiment, the column glass 17 has a double structure of the glass tubes 20 and 21, but a triple structure in which a stiffening glass tube is provided inside the glass tube 20 may be used. If it can stiffen, the number of glass tubes to be fitted is not particularly limited.

また、本実施形態では、円形のガラス管２０と２１で柱ガラス１７を構成しているが、この限りでない。即ち、図１２及び図１３に示すように、３枚の合わせ板ガラス２４を十字型に組み合わせて構成しても同様に実施できる（請求項１０記載の発明）。 Moreover, in this embodiment, although the column glass 17 is comprised with the circular glass tubes 20 and 21, it is not this limitation. That is, as shown in FIG. 12 and FIG. 13, the present invention can be similarly implemented even if the three laminated glass plates 24 are combined in a cross shape.
