Description

本発明は、圧縮力が作用するガラス板の圧縮力作用方向両端部を、躯体側に設ける固定金物の凹溝部に嵌め込んで、各端部毎に、前記凹溝部とのガラス板厚み方向の相対変位を阻止する状態で固定してあるガラス板固定構造とガラス板に関する。   According to the present invention, both end portions of the glass plate on which the compressive force acts are fitted in the concave groove portions of the fixing hardware provided on the housing side, and the glass plate thickness direction with the concave groove portion is provided for each end portion. The present invention relates to a glass plate fixing structure and a glass plate that are fixed in a state of preventing relative displacement.

上記ガラス板固定構造は、ガラス板の圧縮力作用方向両端部を、各端部毎に、凹溝部とのガラス板厚み方向の相対変位を阻止する状態で固定してあるので、両端部を凹溝部とのガラス板厚み方向の相対回転を許容するピン支持状態で固定してある場合に比べて、圧縮力がガラス板の両端部に作用したときの座屈荷重が大きくなるように固定できる。
従来の上記ガラス板固定構造では、ガラス板の傷付きを防止できるように、ガラス板の板面と凹溝部との間などに熱可塑性樹脂製の緩衝材などを挟んで、各端部と凹溝部とのガラス板厚み方向の相対変位を阻止している（周知・慣用技術であり、先行技術文献情報を開示できない）。 In the glass plate fixing structure, both ends of the glass plate in the compressive force acting direction are fixed for each end in a state of preventing relative displacement in the glass plate thickness direction with respect to the concave groove portion. The buckling load when the compressive force is applied to both end portions of the glass plate can be fixed as compared with the case where the pin is supported in a pin supporting state that allows relative rotation in the glass plate thickness direction with the groove.
In the conventional glass plate fixing structure described above, a cushioning material made of a thermoplastic resin or the like is sandwiched between the plate surface of the glass plate and the groove portion so that the glass plate can be prevented from being damaged, and each end portion is recessed. Relative displacement in the thickness direction of the glass plate with the groove is prevented (this is a well-known and commonly used technique and information on prior art documents cannot be disclosed).

このため、火災発生時に、その熱で熱可塑性樹脂製の緩衝材などが軟化したり、溶け出したりして、端部と凹溝部とのガラス板厚み方向での固定が緩むと、端部と凹溝部とがガラス板厚み方向に相対回転し易くなって、端部の固定状態がピン支持に近づき、座屈荷重が小さくなって、座屈が起こり易い欠点がある。
本発明は上記実情に鑑みてなされたものであって、ガラス板の傷付きを防止できるようにしながら、火災発生時に座屈が起こりにくいガラス板固定構造とガラス板を提供することを目的とする。 For this reason, when a fire breaks out, the buffer material made of thermoplastic resin softens or melts by the heat, and the end portion and the groove portion are loosely fixed in the glass plate thickness direction. There is a drawback that the concave groove portion is easily rotated relative to the thickness direction of the glass plate, the fixed state of the end portion approaches the pin support, the buckling load is reduced, and buckling is likely to occur.
This invention is made | formed in view of the said situation, Comprising: It aims at providing the glass plate fixing structure and glass plate which are hard to buckle at the time of fire outbreak, enabling it to prevent the glass plate from being damaged. .

本発明の第１特徴構成は、圧縮力が作用するガラス板の圧縮力作用方向両端部を、躯体側に設ける固定金物の凹溝部に嵌め込んで、各端部毎に、前記凹溝部とのガラス板厚み方向の相対変位を阻止する状態で固定してあるガラス板固定構造であって、弾性係数が前記ガラス板を構成している板ガラスの弾性係数よりも小さく、かつ、耐火性を備えた硬質材料で、前記相対変位を阻止してある点にある。   According to the first characteristic configuration of the present invention, the both ends of the glass plate on which the compressive force acts are fitted in the concave groove portions of the fixed hardware provided on the housing side, and each end portion is connected to the concave groove portion. It is a glass plate fixing structure that is fixed in a state that prevents relative displacement in the thickness direction of the glass plate, and has an elastic coefficient smaller than that of the plate glass constituting the glass plate, and has fire resistance. It is a hard material that prevents the relative displacement.

〔作用及び効果〕
弾性係数がガラス板を構成している板ガラスの弾性係数よりも小さい硬質材料、つまり、板ガラスよりも弾性変形し易い硬質材料で、各端部の凹溝部とのガラス板厚み方向の相対変位を阻止してあるので、ガラス板の傷付きを防止できる。
また、その硬質材料が耐火性を備えているので、火災発生時に、その熱で硬質材料が軟化したり、溶け出したりするおそれが少なくなって、端部と凹溝部とのガラス板厚み方向での固定が緩みにくくなり、座屈荷重の減少を抑制できるので、火災発生時に座屈が起こりにくい。 [Action and effect]
It is a hard material whose elastic modulus is smaller than that of the glass plate constituting the glass plate, that is, a hard material that is more elastically deformable than the plate glass, and prevents relative displacement in the glass plate thickness direction with the groove at each end. Therefore, the glass plate can be prevented from being damaged.
In addition, since the hard material has fire resistance, there is less risk of the hard material softening or melting with the heat in the event of a fire, and in the thickness direction of the glass plate between the end and the groove. Since it is difficult to loosen and the decrease in buckling load can be suppressed, buckling is unlikely to occur in the event of a fire.

本発明の第２特徴構成は、前記各端部毎に、ガラス板面と前記凹溝部との間に前記硬質材料を挟んで、前記相対変位を阻止してある点にある。   The second characteristic configuration of the present invention is that the relative displacement is prevented by sandwiching the hard material between the glass plate surface and the concave groove portion for each of the end portions.

〔作用及び効果〕
各端部毎に、ガラス板面と凹溝部との間に硬質材料を挟んで、端部の凹溝部とのガラス板厚み方向の相対変位を阻止してあるので、凹溝部の溝幅がガラス板の厚みよりも広ければ、ガラス板面と凹溝部との間に挟んだ硬質材料で、各端部の凹溝部とのガラス板厚み方向の相対変位を阻止することができ、凹溝部の溝幅を特に高い精度で加工することなく固定金物を製作したり、凹溝部の躯体側に対する相対位置を特に高い精度で位置決めすることなく固定金物を躯体側に組み付けることができる。 [Action and effect]
For each end part, a hard material is sandwiched between the glass plate surface and the groove part to prevent relative displacement in the glass plate thickness direction with the groove part at the end part. If it is wider than the thickness of the plate, a hard material sandwiched between the glass plate surface and the groove portion can prevent relative displacement in the glass plate thickness direction with the groove portion at each end, and the groove of the groove portion The fixed hardware can be manufactured without processing the width with particularly high accuracy, or the fixed hardware can be assembled to the housing without positioning the relative position of the concave groove portion with respect to the housing with particularly high accuracy.

本発明の第３特徴構成は、前記硬質材料がアルミニウム又はアルミニウム合金である点にある。   A third characteristic configuration of the present invention is that the hard material is aluminum or an aluminum alloy.

〔作用及び効果〕
ガラス板を構成している板ガラスの弾性係数よりも小さく、かつ、耐火性を備えた硬質材料が、安価に入手し易いアルミニウム又はアルミニウム合金であるので、施工コストを安くすることができる。 [Action and effect]
Since the hard material which is smaller than the elastic coefficient of the plate glass constituting the glass plate and has fire resistance is aluminum or aluminum alloy which is easily available at low cost, the construction cost can be reduced.

本発明の第４特徴構成は、第１〜第３特徴構成のガラス板固定構造に使用するガラス板であって、複数枚の板ガラスの板面どうしを熱可塑性樹脂製中間膜を介して接合してある合わせガラスで、その合わせガラスの前記両端部において、前記熱可塑性樹脂製中間膜に代えて、耐火性が前記熱可塑性樹脂製中間膜よりも高い前記硬質材料製スペーサーを挟んで構成してある点にある。   A fourth characteristic configuration of the present invention is a glass plate used for the glass plate fixing structure according to the first to third characteristic configurations, wherein the plate surfaces of a plurality of plate glasses are joined together through an intermediate film made of a thermoplastic resin. In the laminated glass, the both ends of the laminated glass are configured by sandwiching the hard material spacer having a higher fire resistance than that of the thermoplastic resin intermediate film instead of the thermoplastic resin intermediate film. There is a point.

〔作用及び効果〕
圧縮力が作用するガラス板が、複数枚の板ガラスの板面どうしを熱可塑性樹脂製中間膜を介して接合してある合わせガラスの場合は、火災発生時に、その熱で中間膜が軟化したり、溶け出したりして、板ガラスの板面どうしの間隔が狭くなって厚みが減少し、端部と凹溝部とのガラス板厚み方向での固定が緩むおそれがある。
上記に対して、そのような合わせガラスの両端部において、熱可塑性樹脂製中間膜に代えて、弾性係数が板ガラスの弾性係数よりも小さく、かつ、耐火性がその熱可塑性樹脂製中間膜よりも高い硬質材料製スペーサーを挟んで構成してあるので、火災発生時に、その熱で中間膜が軟化したり、溶け出したりしても、両端部における凹溝部とのガラス板厚み方向での固定が緩みにくくなり、座屈荷重の減少を抑制できるので、圧縮力が作用するガラス板として合わせガラスを使用した場合でも、火災発生時に座屈が起こりにくい。 [Action and effect]
In the case of a laminated glass in which the glass plate on which the compressive force acts is bonded to each other through a thermoplastic resin intermediate film, the intermediate film is softened by the heat in the event of a fire. Then, it melts out, the distance between the plate surfaces of the plate glass becomes narrow, the thickness decreases, and the fixing of the end portion and the groove portion in the thickness direction of the glass plate may be loosened.
In contrast to the above, at both ends of such a laminated glass, instead of the thermoplastic resin intermediate film, the elastic modulus is smaller than the elastic coefficient of the plate glass, and the fire resistance is higher than that of the thermoplastic resin intermediate film. Since it is configured with a spacer made of a hard material, even if the intermediate film is softened or melted by the heat in the event of a fire, it can be fixed in the glass plate thickness direction with the concave groove at both ends. Since it becomes difficult to loosen and a decrease in buckling load can be suppressed, even when laminated glass is used as a glass plate on which a compressive force acts, buckling is unlikely to occur in the event of a fire.

本発明の第５特徴構成は、第１〜第３特徴構成のガラス板固定構造に使用するガラス板であって、複数枚の板ガラスの周縁どうしを熱可塑性樹脂製シール材及びスペーサーを挟んで一体化してある複層ガラスで、その複層ガラスの前記両端部において、前記熱可塑性樹脂製シール材及びスペーサーとは別に、前記耐火性が前記熱可塑性樹脂製シール材よりも高い前記硬質材料製スペーサーを挟んで一体化して構成してある。   A fifth characteristic configuration of the present invention is a glass plate used for the glass plate fixing structure according to the first to third characteristic configurations, and the peripheral edges of a plurality of plate glasses are integrated with a thermoplastic resin sealing material and a spacer interposed therebetween. The hard material spacer having a fire resistance higher than that of the thermoplastic resin sealing material, in addition to the thermoplastic resin sealing material and spacer, at the both end portions of the multilayer glass. It is configured to be integrated with a pinch.

〔作用及び効果〕
圧縮力が作用するガラス板が、複数枚の板ガラスの周縁どうしを熱可塑性樹脂製シール材及びスペーサーを挟んで一体化してある複層ガラスの場合は、火災発生時に、その熱でシール材が軟化したり、溶け出したりして、板ガラスのガラス板面どうしの間隔が狭くなって周縁部の厚みが減少し、端部と凹溝部とのガラス板厚み方向での固定が緩むおそれがある。
上記に対して、そのような複層ガラスの両端部において、熱可塑性樹脂製シール材及びスペーサーとは別に、弾性係数が板ガラスの弾性係数よりも小さく、かつ、耐火性がその熱可塑性樹脂製シール材よりも高い硬質材料製スペーサを挟んで一体化して構成してあるので、火災発生時に、その熱でシール材が軟化したり、溶け出したりしても、両端部における凹溝部とのガラス板厚み方向での固定が緩みにくくなり、座屈荷重の減少を抑制できるので、圧縮力が作用するガラス板として複層ガラスを使用した場合でも、火災発生時に座屈が起こりにくい。 [Action and effect]
If the glass plate on which the compressive force acts is a multi-layer glass in which the peripheral edges of a plurality of plate glasses are integrated with a thermoplastic resin sealing material and a spacer in between, the sealing material is softened by the heat in the event of a fire Or melting out, the distance between the glass plate surfaces of the plate glass is narrowed, the thickness of the peripheral portion is reduced, and the fixing of the end portion and the recessed groove portion in the glass plate thickness direction may be loosened.
In contrast to the above, at both ends of such a multilayer glass, apart from the thermoplastic resin sealing material and the spacer, the elastic modulus is smaller than the elastic modulus of the sheet glass, and the fireproof seal is made of the thermoplastic resin. Since it is integrated and sandwiched with a spacer made of hard material higher than the material, even if the seal material softens or melts due to the heat in the event of a fire, the glass plate with the groove at both ends Fixing in the thickness direction is difficult to loosen and the reduction in buckling load can be suppressed, so that even when a multilayer glass is used as a glass plate on which a compressive force acts, buckling is unlikely to occur in the event of a fire.
