Description

本発明は、ガラスを支持するセッティングブロックを有する建具に関する。 The present invention relates to fittings having a setting block that supports glass.

従来から、室内外を仕切るガラスがセッティングブロックにより支持されている建具は知られている(例えば、特許文献1参照)。この建具は、室内外を仕切る複層ガラスが框に装着された障子を有しており、框を構成し複層ガラスの下に配置される下框に設けられているガラス載置部にセッティングブロックを介して複層ガラスが載置されている。複層ガラス及びセッティングブロックが載置されるガラス載置部には、火災等により加熱された複層ガラスの割れを防止すべく熱膨張性黒鉛(加熱発泡材)も設けられており、加熱発泡材は、下框の長手方向における全域に配置されている。このため、セッティングブロックには、熱膨張性黒鉛との干渉を防ぐために凹部が設けられている。 Conventionally, there are known fittings in which the glass that separates the interior and exterior is supported by a setting block (see, for example, Patent Document 1). This fitting has a shoji with double glazing that separates the interior and exterior attached to the stile, and is set on the glass mounting part provided on the lower stile that constitutes the stile and is placed under the double glazing. Double glazing is placed via the block. The glass mounting part on which the double glazing and the setting block are placed is also provided with heat-expandable graphite (heated foam material) to prevent the double glazing heated by a fire or the like from cracking, and is heated and foamed. The materials are arranged over the entire area in the longitudinal direction of the lower stile. Therefore, the setting block is provided with a recess in order to prevent interference with the heat-expandable graphite.

特開2014−224391号公報Japanese Unexamined Patent Publication No. 2014-224391

上記従来の建具では、セッティングブロックに、熱膨張性黒鉛との干渉を防ぐために凹部が設けられているので、セッティングブロックの下面において、ガラス載置部に当接して複層ガラスを支持している領域は、複層ガラスの厚みよりも狭い。このため、上記従来の建具では、複層ガラスが備える2枚のガラス板の一方のみがセッティングブロックにおいてガラス載置部に当接している部位の上に位置している。近年、建具のガラスとして3枚のガラス板を備えた、所謂トリプルガラスが用いられているものがある。トリプルガラスは重量が複層ガラスより大きいため、より安定した状態で支持することが求められる。
本発明は、かかる課題に鑑みてなされたものであり、その目的とするところは、トリプルガラスをより安定した状態で支持しつつ防火性に優れた建具を提供することにある。
In the above-mentioned conventional fittings, since the setting block is provided with a recess to prevent interference with the heat-expandable graphite, the lower surface of the setting block is in contact with the glass mounting portion to support the double glazing. The area is narrower than the thickness of the double glazing. For this reason, in the conventional fitting, only one of the two glass plates included in the double glazing is located above the portion of the setting block that is in contact with the glass mounting portion. In recent years, so-called triple glass having three glass plates has been used as the glass for fittings. Since triple glazing is heavier than double glazing, it is required to support it in a more stable state.
The present invention has been made in view of such a problem, and an object of the present invention is to provide a fitting having excellent fire resistance while supporting triple glass in a more stable state.

かかる目的を達成するための主たる発明は、耐熱強化ガラスを含む3枚のガラス板を備え屋内外を仕切るトリプルガラスと、前記トリプルガラスを保持し、内周側に前記トリプルガラスの周縁部を収容し前記トリプルガラスの端面と対向する見込み面部を備えたガラス収容部を有する枠体と、前記ガラス収容部内に設けられ前記トリプルガラスが載置されるセッティングブロックと、前記ガラス収容部内に設けられる加熱発泡材と、を有し、前記加熱発泡材及び前記セッティングブロックは、前記見込み面部上に配置され、前記セッティングブロックは、前記トリプルガラスの前記端面が当接されるガラス当接部と、前記見込み面部に当接される見込み面部当接部と、見込み面部当接部の見込み方向に隣接させて設けられ前記加熱発泡材が配置される空隙を形成する空隙形成部と、を有し、前記セッティングブロックの前記見込み面部当接部は、前記3枚の前記ガラス板のうちの最も屋外側に位置する前記ガラス板と真ん中に位置する前記ガラス板とに亘って配置されていることを特徴とする建具である。
本発明の他の特徴については、本明細書及び添付図面の記載により明らかにする。
The main invention for achieving such an object is to hold a triple glass having three glass plates including heat-resistant tempered glass to partition indoors and outdoors, and to hold the triple glass and to accommodate a peripheral portion of the triple glass on the inner peripheral side. A frame having a glass accommodating portion having a prospective surface portion facing the end face of the triple glass, a setting block provided in the glass accommodating portion on which the triple glass is placed, and heating provided in the glass accommodating portion. The heated foam material and the setting block are arranged on the prospective surface portion, and the setting block is a glass contact portion with which the end surface of the triple glass is abutted and the prospective surface portion. The setting includes a prospective surface contact portion that comes into contact with the surface portion and a gap forming portion that is provided adjacent to the prospective surface portion contact portion in the prospective direction and forms a gap in which the heated foam material is arranged.

以下、本発明の一実施形態に係る建具について図面を参照して説明する。
本実施形態においては、図1に示すように、屋内外を仕切るトリプルガラス2を備えたFIX窓用の建具1を例に挙げて説明する。
Hereinafter, fittings according to an embodiment of the present invention will be described with reference to the drawings.
In the present embodiment, as shown in FIG. 1, a fitting 1 for a FIX window provided with triple glass 2 for partitioning indoors and outdoors will be described as an example.

以下の説明においては、建物等に取り付けられた状態の建具1を屋外側から見たときに、上下となる方向を上下方向、左右となる方向を左右方向、屋内外方向である奥行き方向を見込み方向として示す。建具1の各部位であっても、また、建具1を構成する各部材については単体の状態であっても、建具1が取り付けられた状態で上下方向、左右方向、見込み方向等となる方向にて方向を特定して説明する。 In the following explanation, when the fitting 1 attached to a building or the like is viewed from the outdoor side, the vertical direction is the vertical direction, the horizontal direction is the horizontal direction, and the indoor / outdoor direction is the depth direction. Shown as direction. Even if it is each part of the fitting 1 or each member constituting the fitting 1 is in a single state, in the vertical direction, the horizontal direction, the prospective direction, etc. with the fitting 1 attached. The direction will be specified and explained.

本実施形態の建具1は、図2、図3に示すように、耐熱強化ガラスを含む3枚のガラス板20、21、22を備えたトリプルガラス2と、トリプルガラス2の周端部を収容するガラス収容部3aを備えた枠体としてのFIX枠3と、を有している。 As shown in FIGS. 2 and 3, the fitting 1 of the present embodiment accommodates a triple glass 2 having three glass plates 20, 21 and 22 including heat-resistant tempered glass, and a peripheral end portion of the triple glass 2. It has a FIX frame 3 as a frame body provided with a glass accommodating portion 3a.

トリプルガラス2は、3枚のガラス板20、21、22が、周縁部に設けられたスペーサー2aにより互いに間隔を空けて対面させて配置され一体をなしている。3枚のガラス板20、21、22は、2枚のLow−Eガラス20、22と、1枚の耐熱強化ガラス21により構成されており、2枚のLow−Eガラス20、22の間に耐熱強化ガラス21が設けられている。 In the triple glass 2, three glass plates 20, 21, and 22 are arranged so as to face each other at a distance from each other by a spacer 2a provided on a peripheral edge portion to form an integral body. The three glass plates 20, 21 and 22 are composed of two Low-E glasses 20 and 22 and one heat-resistant tempered glass 21 between the two Low-E glasses 20 and 22. Heat resistant tempered glass 21 is provided.

FIX枠3は、合成樹脂製の押し出し成形材でなりトリプルガラス2の上に位置する上の枠材30、トリプルガラス2の下に位置する下の枠材30、及び、トリプルガラス2の左右に位置する左右の縦の枠材30をなす4本の枠材30が矩形状に接合された枠本体31と、各枠材30に嵌合される押縁32と、を有している。 The FIX frame 3 is made of an extruded material made of synthetic resin, and is located on the upper frame material 30 located above the triple glass 2, the lower frame material 30 located below the triple glass 2, and on the left and right sides of the triple glass 2. It has a frame body 31 in which four frame members 30 forming the left and right vertical frame members 30 are joined in a rectangular shape, and a ridge 32 fitted to each frame member 30.

4本の枠材30は、長尺の成形材を所定の長さに切断して形成されているため同一の断面形状をなしている。各枠材30の端部は長手方向に対して45度の角度をなすように切断され、互いに隣り合う枠材30の端部同士を突き合わせた状態で溶着し矩形状の枠本体31が形成されている。各枠材30の断面形状は同一なので、ここでは、図面にて下の枠材30を示して枠構造を説明する。以下の説明では、各枠材30に共通する説明となるように、下の枠材30の上側を、枠本体31の内周側(以下、内周側という)とし、下の枠材30の下側を枠本体31の外周側(以下、外周側という)として説明する。 The four frame members 30 have the same cross-sectional shape because they are formed by cutting a long molding material to a predetermined length. The ends of each frame member 30 are cut so as to form an angle of 45 degrees with respect to the longitudinal direction, and the ends of the frame members 30 adjacent to each other are welded to each other so as to form a rectangular frame body 31. ing. Since the cross-sectional shape of each frame member 30 is the same, here, the frame structure will be described by showing the frame member 30 below in the drawings. In the following description, the upper side of the lower frame material 30 is referred to as the inner peripheral side (hereinafter referred to as the inner peripheral side) of the frame main body 31 so as to be a common explanation for each frame material 30, and the lower frame material 30 The lower side will be described as the outer peripheral side of the frame main body 31 (hereinafter, referred to as the outer peripheral side).

下の枠材30は、図4に示すように、トリプルガラス2がセッティングブロック4を介して載置され当該トリプルガラス2の端面2bと対向する枠見込み面部30aと、枠見込み面部30aの屋内側にて内周側に突出する枠内周突出部30bと、枠見込み面部30aの屋外側に設けられ押縁32が嵌合される枠押縁嵌合部30cと、枠見込み面部30aの外周側に間隔を空けて対向する枠外周対向面部30dと、枠外周対向面部30dから外周側に延出されて躯体6に固定される躯体固定部30eと、を有している。 As shown in FIG. 4, the lower frame member 30 has a frame prospective surface portion 30a on which the triple glass 2 is placed via the setting block 4 and faces the end surface 2b of the triple glass 2 and an indoor side of the frame prospective surface portion 30a. The space between the frame inner peripheral protrusion 30b protruding toward the inner peripheral side, the frame ridge fitting portion 30c provided on the outdoor side of the frame prospective surface portion 30a and into which the ridge 32 is fitted, and the outer peripheral side of the frame prospective surface portion 30a. It has a frame outer peripheral facing surface portion 30d facing the frame outer peripheral facing surface portion 30d, and a skeleton fixing portion 30e extending from the frame outer peripheral facing surface portion 30d to the outer peripheral side and being fixed to the skeleton 6.

枠見込み面部30aの屋内側の縁から内周側に突出する枠内周突出部30bは、突出している先端側に屋外側に向かって突出させて設けられるビード7が嵌合される枠ビード嵌合部30fを有しており、枠内周突出部30bにおける枠ビード嵌合部30fよりも枠見込み面部30a側には、枠ビード嵌合部30fの屋外側の縁と、見込み方向においてほぼ同じ位置に枠見付け面30gが形成されている。 The frame inner peripheral protrusion 30b projecting from the indoor side edge of the frame prospective surface portion 30a to the inner peripheral side is fitted with a frame bead 7 into which a bead 7 provided so as to project toward the outdoor side is fitted to the protruding tip side. It has a joint portion 30f, and is substantially the same as the outdoor edge of the frame bead fitting portion 30f on the frame prospective surface portion 30a side of the frame bead fitting portion 30f in the frame inner peripheral protrusion 30b in the prospective direction. A frame finding surface of 30 g is formed at the position.

下の枠材30の枠見込み面部30aと枠外周対向面部30dとの間には、長手方向に貫通する枠中空部30hが設けられている。枠中空部30hは、枠見込み面部30aの見込み方向における両端部から外周側に延出されて枠外周対向面部30dと繋がる2つの枠連結壁部30iによって仕切られてほぼ矩形状をなしている。2つの枠連結壁部30iは、見込み方向において互いに対向している。 A frame hollow portion 30h penetrating in the longitudinal direction is provided between the frame prospective surface portion 30a of the lower frame member 30 and the frame outer peripheral facing surface portion 30d. The frame hollow portion 30h has a substantially rectangular shape and is partitioned by two frame connecting wall portions 30i extending from both ends of the frame prospective surface portion 30a in the prospective direction to the outer peripheral side and connecting to the frame outer peripheral facing surface portion 30d. The two frame connecting wall portions 30i face each other in the prospective direction.

枠中空部30h内には、長手方向に沿い全長にわたってアルミニウム合金製の押し出し成形材でなる補強部材8が設けられている。補強部材8については後述する。 A reinforcing member 8 made of an extruded aluminum alloy material is provided in the hollow frame portion 30h along the longitudinal direction over the entire length. The reinforcing member 8 will be described later.

枠押縁嵌合部30cは、枠見込み面部30aよりも屋外側に設けられ、枠見込み面部30aよりも外周側に窪んで押縁32の嵌合片32aが嵌合される。枠押縁嵌合部30cは、屋外側の枠連結壁部30iの屋外側にて枠見込み面部30aよりも外周側に位置する枠底部30jを有する2つの枠凹部30k、30lのうちの屋外側の枠凹部30kである。屋内側の枠凹部30lの屋内側の縁30mは、枠見込み面部30aの屋外側の縁と繋がり、外周面が円弧状をなしている。 The frame ridge fitting portion 30c is provided on the outdoor side of the frame prospective surface portion 30a, and is recessed on the outer peripheral side of the frame prospective surface portion 30a to fit the fitting piece 32a of the ridge 32. The frame ridge fitting portion 30c is located on the outdoor side of the two frame recesses 30k and 30l having a frame bottom portion 30j located on the outer side of the frame prospective surface portion 30a on the outdoor side of the frame connecting wall portion 30i on the outdoor side. The frame recess is 30k. The indoor side edge 30m of the indoor side frame recess 30l is connected to the outdoor side edge of the frame prospective surface portion 30a, and the outer peripheral surface has an arc shape.

押縁32は、嵌合片32aが枠押縁嵌合部30cに嵌合された状態で、枠内周突出部30bと見込み方向に対向し、枠本体31とともにトリプルガラス2の周縁部が収容されるガラス収容部3aを形成する。すなわち、ガラス収容部3aは、枠本体31に嵌合された押縁32と、屋内側の枠凹部30lと、枠見込み面部30aと、枠内周突出部30bとにより囲まれた空間である。 The ridge 32 faces the inner peripheral protrusion 30b of the frame in the prospective direction in a state where the fitting piece 32a is fitted to the frame ridge fitting portion 30c, and the peripheral edge portion of the triple glass 2 is accommodated together with the frame body 31. A glass accommodating portion 3a is formed. That is, the glass accommodating portion 3a is a space surrounded by a ridge 32 fitted to the frame main body 31, a frame recess 30l on the indoor side, a frame prospective surface portion 30a, and a frame inner peripheral protrusion 30b.

ガラス収容部3aに周縁部が収容されたトリプルガラス2は、ガラス収容部3aに設けられるセッティングブロック4により面内方向の位置が規制されてガラス保持金具9に保持され、枠内周突出部30bのビード7と、押縁32の先端に設けられたビード32bとにより挟持される。このとき、トリプルガラス2の屋内側の面2cは、枠内周突出部30bのビード7に押圧され、枠内周突出部30bの枠見付け面30gと見込み方向に間隔を空けて配置されている。また、トリプルガラス2の屋外側の面2dは、枠見込み面部30aと屋内側の枠凹部30lとの境界付近に位置している。ガラス保持金具9については後述する。 The triple glass 2 whose peripheral edge is accommodated in the glass accommodating portion 3a is held by the glass holding metal fitting 9 whose position in the in-plane direction is restricted by the setting block 4 provided in the glass accommodating portion 3a, and the inner peripheral protrusion 30b of the frame is held. It is sandwiched between the bead 7 and the bead 32b provided at the tip of the ridge 32. At this time, the indoor side surface 2c of the triple glass 2 is pressed by the bead 7 of the frame inner peripheral protrusion 30b, and is arranged at a distance from the frame finding surface 30g of the frame inner peripheral protrusion 30b in the prospective direction. .. Further, the outdoor side surface 2d of the triple glass 2 is located near the boundary between the frame prospective surface portion 30a and the indoor side frame recess 30l. The glass holding metal fitting 9 will be described later.

躯体固定部30eは、枠外周対向面部30dにおいて枠中空部30hとは反対側となる外周面側から外周方向に延出されており、枠中空部30hを仕切る屋外側の枠連結壁部30iより僅かに屋内側に設けられている。このため、ガラス収容部3aに周縁部が収容されたトリプルガラス2は、最も屋外側に位置するガラス板(以下、最外ガラス板という)20が、躯体固定部30eを上方に延長した位置に配置されており、最外ガラス板20よりも屋内側の部位が躯体6上に位置している。 The skeleton fixing portion 30e extends in the outer peripheral direction from the outer peripheral surface side opposite to the frame hollow portion 30h in the frame outer peripheral facing surface portion 30d, and extends from the frame connecting wall portion 30i on the outdoor side that partitions the frame hollow portion 30h. It is slightly installed on the indoor side. Therefore, in the triple glass 2 in which the peripheral edge portion is housed in the glass accommodating portion 3a, the glass plate 20 located on the outermost side (hereinafter referred to as the outermost glass plate) 20 is located at a position where the skeleton fixing portion 30e is extended upward. It is arranged, and the portion on the indoor side of the outermost glass plate 20 is located on the skeleton 6.

下の枠材30の躯体固定部30eは、屋外側から進入するビス33により躯体6に固定されるが、上及び縦の枠材30の躯体固定部30eは、図2、図3に示すように、補強金具5と共に屋外側から進入するビス33により躯体6に固定される。尚、下の枠材30の躯体固定部30eも補強金具5と共に屋外側から進入するビス33により躯体6に固定されていても構わない。 The skeleton fixing portion 30e of the lower frame member 30 is fixed to the skeleton 6 by a screw 33 entering from the outdoor side, and the skeleton fixing portion 30e of the upper and vertical frame members 30 is as shown in FIGS. In addition, it is fixed to the skeleton 6 by a screw 33 that enters from the outdoor side together with the reinforcing metal fitting 5. The skeleton fixing portion 30e of the lower frame member 30 may also be fixed to the skeleton 6 by a screw 33 entering from the outdoor side together with the reinforcing metal fitting 5.

枠中空部30hに設けられている補強部材8は、枠見込み面部30aと対向し見込み方向のほぼ全域に設けられる対向板部としての見込み面補強部8aと、見込み面補強部8aから外周方向に延出された2つの延出補強部8bと、を有している。見込み面補強部8aは、枠見込み面部30aの反対側に設けられる後述する固定金具90を固定するビス34が螺合可能な厚みを有している。見込み面補強部8aの枠見込み面部30a側の面には、長手方向に沿う補強部材凹部8cが屋内側の端部近傍と、見込み方向における中央より屋外側寄りの部位との2カ所に設けられており、補強部材凹部8c内には、加熱発泡材10が設けられている。 The reinforcing member 8 provided in the hollow frame portion 30h is opposed to the frame prospective surface portion 30a and is provided in almost the entire area in the prospective direction. It has two extension reinforcing portions 8b, which are extended. The prospective surface reinforcing portion 8a has a thickness to which a screw 34 for fixing a fixing metal fitting 90, which will be described later, provided on the opposite side of the prospective surface portion 30a of the frame can be screwed. On the surface of the prospective surface reinforcing portion 8a on the frame prospective surface portion 30a side, reinforcing member recesses 8c along the longitudinal direction are provided at two locations, one near the end on the indoor side and the other on the outdoor side from the center in the prospective direction. A heated foaming material 10 is provided in the reinforcing member recess 8c.

2つの延出補強部8bは、見込み方向に互いに間隔を空けて設けられており、それぞれ見込み面補強部8aに設けられた加熱発泡材10の屋外側の端部近傍に配置されている。屋外側の延出補強部8bの先端には、見込み方向における両方向に延出された補強部材延出片8dが設けられており、屋内側の延出補強部8bの先端には、屋内側に延出された補強部材延出片8dが設けられている。屋外側の延出補強部8bの先端にて屋内側に延出された補強部材延出片8dは、上及び縦の枠材30の躯体固定部30eとともに躯体6の見付け面6aに固定される補強金具5と補強部材8とを繋ぐビス35が螺合可能な厚みを有している。 The two extension reinforcing portions 8b are provided so as to be spaced apart from each other in the prospective direction, and are arranged in the vicinity of the outdoor end portion of the heated foaming material 10 provided in the prospective surface reinforcing portion 8a, respectively. The tip of the extension reinforcing portion 8b on the outdoor side is provided with a reinforcing member extension piece 8d extending in both directions in the prospective direction, and the tip of the extension reinforcement portion 8b on the indoor side is on the indoor side. An extended reinforcing member extension piece 8d is provided. The reinforcing member extension piece 8d extended to the indoor side at the tip of the extension reinforcing portion 8b on the outdoor side is fixed to the finding surface 6a of the skeleton 6 together with the skeleton fixing portion 30e of the upper and vertical frame members 30.

FIX枠3にトリプルガラス2を取り付ける方法は、まず、各枠材30にセッティングブロック4及び固定金具90を取り付ける。セッティングブロック4は、下の枠材30には、載置するだけでも構わない。取り付けられた固定金具90は、屋内延出片90eの先端が、枠材30の枠見付け面30gに当接している。この状態で、固定金具90の屋内内周延出部90cの屋外側の面が、トリプルガラス2の屋内側の面2cが配置されるべき位置に配置されている。すなわち、セッティングブロック4の見込み面部当接部4aが、3枚のガラス板20、21、22のうちの屋外側に位置する2枚のガラス板20、21の下に亘るように配置されたトリプルガラス2の屋内側の面2cと内周延出部90cの屋外側の面とが対向するように、固定金具90が取り付けられる。 In the method of attaching the triple glass 2 to the FIX frame 3, first, the setting block 4 and the fixing bracket 90 are attached to each frame member 30. The setting block 4 may be simply placed on the lower frame member 30. In the attached fixing bracket 90, the tip of the indoor extension piece 90e is in contact with the frame finding surface 30g of the frame material 30. In this state, the outdoor side surface of the indoor inner peripheral extending portion 90c of the fixing bracket 90 is arranged at a position where the indoor side surface 2c of the triple glass 2 should be arranged. That is, a triple arranged so that the prospective surface contact portion 4a of the setting block 4 extends under the two glass plates 20, 21 located on the outdoor side of the three glass plates 20, 21, 22. The fixing bracket 90 is attached so that the indoor side surface 2c of the glass 2 and the outdoor side surface of the inner peripheral extending portion 90c face each other.

次に、枠本体31にセッティングブロック4及び固定金具90が取り付けられた状態で、トリプルガラス2を、下の枠材30に設けられているセッティングブロック4上に載置するとともに各枠材30に設けられているセッティングブロック4の内周側に配置し、屋内側の面2cを固定金具90の屋内内周延出部90cと対向させる。このとき、見込み面部当接部4aが、屋外側に位置する2枚のガラス板20、21の下に亘って配置される位置にトリプルガラス2が配置される。 Next, with the setting block 4 and the fixing bracket 90 attached to the frame body 31, the triple glass 2 is placed on the setting block 4 provided in the lower frame member 30, and is placed on each frame member 30.
