Description
【考案の詳細な説明】 本考案はガラス板の施工構造に関する。[Detailed explanation of the idea] The present invention relates to a construction structure for glass plates.
一般に大型ガラス板の側縁をサツシ枠溝中にシリコンシ
ーラント等の弾性シーリング剤を用いて弾力的に固定す
る場合、シーリング剤をサツシ枠溝内に完全充填するこ
とはなく、ガラス板両面とサツシ枠溝内壁との間の空隙
部奥側に弾性バックアツプ材を詰め、このバックアツプ
材上の空隙部に弾性シーリング剤を充填する構造をとっ
ている。Generally, when the side edges of a large glass plate are elastically fixed in the sash frame groove using an elastic sealant such as silicone sealant, the sealant is not completely filled into the sash frame groove, and both sides of the glass plate and the sash are The structure is such that an elastic back-up material is filled in the back of the gap between the inner wall of the frame groove and an elastic sealant is filled in the gap above the back-up material.
なおこのような構造をとるのは、弾性シーリング剤がガ
ラスエツジよりも奥側に入り込むことにより複雑な応力
分布および剥離を生じ易いいわゆる三面接着構造となる
のを避け、接着が相対向する二面間のみで行なわれるよ
うにするため、あるいは比較的高価である弾性シーリン
グ剤を節減するためなどの理由による。The purpose of this structure is to avoid a so-called three-sided adhesive structure, where the elastic sealant penetrates deeper than the glass edge, resulting in a complex stress distribution and peeling. This is for reasons such as making it possible to use only a single sealant, or saving on the use of relatively expensive elastic sealants.
上記施工構造において従来はバックアツプ材の材質とし
て比較的硬質のゴム片を用いていたため次のような問題
があった。Conventionally, in the construction structure described above, a relatively hard piece of rubber was used as the backup material, which caused the following problems.
すなわち安価な鋼材を用いたサツシ枠では反り、よじれ
等があって直線性が損なわれている場合が多くこのため
ガラス板もサツシ枠の形状に従って変形するためガラス
板の平坦度が損われ、またサツシ枠内壁の凹凸によりガ
ラス板に局部的な負荷が加わり、ガラス板に写る反射映
像が歪んでガラススクリーン個有の美観が損なわれると
いう問題があった。In other words, sash frames made of inexpensive steel often have warps, kinks, etc. that impair their straightness.As a result, the glass plate also deforms according to the shape of the sash frame, impairing the flatness of the glass plate. There was a problem in that the unevenness of the inner wall of the sash frame placed a local load on the glass plate, distorting the image reflected on the glass plate and detracting from the unique beauty of the glass screen.
一方上記問題を回避すべく軟質のバックアツプ材を使用
すると弾性シーリング剤の充填時にバックアツプ材が局
部的に大きく凹みシーリング剤の接着面積がガラス板の
辺に沿い不均一となり、このため設計通りの耐負荷性能
が得られないという事態も生じてくる。On the other hand, if a soft back-up material is used to avoid the above problem, the back-up material will be locally greatly dented when filled with the elastic sealant, and the adhesive area of the sealant will be uneven along the sides of the glass plate. A situation may arise in which load-bearing performance cannot be obtained.
本考案は大型ガラスの施工における上記従来の問題点を
解決するガラス板施工構造を提供するものである。The present invention provides a glass plate construction structure that solves the above-mentioned conventional problems in the construction of large-sized glass.
以下本考案を図面に示した実施例につき説明する。The present invention will be described below with reference to embodiments shown in the drawings.
第1図ははめころし窓の断面視を示し、サツシ枠1の溝

シ枠溝内壁1aとの間の空隙部奥側にバックアツプ材4
を詰め、バックアツプ材4上の前記空隙部にシリコンシ
ーラント等の弾性シーリング剤5を充填して構成される
。Fig. 1 shows a cross-sectional view of a sliding window, in which the side edge of the glass plate 2 is fitted into the groove of the sash frame 1, and its lower edge is placed on the setting block 3, and both sides of the glass plate and the sash frame are placed. A back-up material 4 is placed on the back side of the gap between the groove inner wall 1a.
The gap on the back-up material 4 is filled with an elastic sealant 5 such as a silicone sealant.
上記施工構造において本考案ではバックアツプ材4とし
て、ガラス板2の面法線方向に圧縮歪率(単位荷重に対
する変形量)が大でガラス板の面平行方向には相対的に
圧縮歪率の小な弾性材質のものを用いる。In the above construction structure, the back-up material 4 of the present invention has a large compressive strain rate (amount of deformation per unit load) in the direction normal to the surface of the glass plate 2, and a relatively low compressive strain rate in the direction parallel to the surface of the glass plate. Use a small piece of elastic material.
−例を挙げると、ガラス繊維等の無機繊維をバインダー
で積層した無機繊維マットを条片に切断し、比較的軟質
である繊維の積層方向をガラス板2の法線方向に一致さ
せ、且つ圧縮力に対して腰の強い繊維の長さ方向がガラ
ス板2面と平行になるように端面の向きを選んでバック
アツプ材4として使用する。- For example, an inorganic fiber mat made by laminating inorganic fibers such as glass fibers with a binder is cut into strips, the laminating direction of the relatively soft fibers is aligned with the normal direction of the glass plate 2, and the mat is compressed. The fibers, which are strong against force, are used as a back-up material 4 by selecting the direction of the end face so that the length direction thereof is parallel to the glass plate 2 surface.
上記の如きバックアツプ材4を用いることにより、ガラ
ス板面に写る反射映像の歪みの原因となるバックアツプ
材4のガラス板に対する押圧力を相対的に小さく抑える

対的に剛性が大であるためシーリング剤5の充填吐出圧
および重量により大きく変形することがなくガラス板の
辺に沿い接着厚み寸法の一様なシーリング層が得られる
。By using the back-up material 4 as described above, the pressing force of the back-up material 4 against the glass plate, which causes distortion of the reflected image reflected on the glass plate surface, can be kept relatively small, and the sealant 5 can be kept relatively small. Since it has relatively high rigidity in the supporting direction, it will not be significantly deformed by the filling and discharging pressure and weight of the sealant 5, and a sealing layer with a uniform adhesive thickness dimension along the sides of the glass plate can be obtained.
バックアツプ材4の断面形状については特に限定はない
がガラス板面に対する接触面積は可及的に小さくするこ
とが望ましく、この点で第1図、第2図に示す如くバッ
クアツプ材4の断面形状をシーリング剤5の載る上面の
幅11よりも下面の幅12を小としてほぼ逆台形状とし
ておくのが好ましい。There is no particular limitation on the cross-sectional shape of the back-up material 4, but it is desirable to make the contact area with the glass plate surface as small as possible. It is preferable that the shape is approximately an inverted trapezoid, with the width 12 of the lower surface being smaller than the width 11 of the upper surface on which the sealant 5 is placed.

Since there is a risk that the back-up material 4 may fall off or become misaligned after insertion, the bottom surface of the back-up material 4 is attached to the bottom wall of the groove of the sash frame 1 via an adhesive layer 6 as shown in FIG. It is best to wear clothes.
