Description

本発明は、可撓性を有するシートを枠に固着して構成される防煙用の垂れ壁部材とそれを用いて構成される垂れ壁に関する。 The present invention relates to a drooping wall member for smoke prevention constituted by fixing a flexible sheet to a frame, and a drooping wall constituted using the same.

ビルや大型店舗あるいは公共施設等の比較的大型の建築物には、従来より、火災等によって発生する煙の流動を妨げるため、天井に垂れ壁が取付けられる。このような垂れ壁としては、開放感を得るという意匠上の観点から、従来より、透明の網入りガラスパネルを使用してきた。しかしながら、ガラスパネルは地震等で天井に設置された状態で割れてガラスの破片が落下したり、落下した衝撃で割れたりするおそれがあり、ガラス片の飛散により避難を阻害したり、機械設備の不具合が発生する要因となる等の問題があった。 In a relatively large building such as a building, a large store, or a public facility, a hanging wall is conventionally attached to the ceiling to prevent the flow of smoke generated by a fire or the like. As such a drooping wall, a transparent netted glass panel has heretofore been used from the viewpoint of design to obtain an open feeling. However, glass panels may break when installed on the ceiling due to an earthquake, etc., and glass fragments may fall or break due to the impact of falling. There were problems such as causing a failure.

このようなガラスパネル使用の際の不具合を回避するため、従来からガラスパネルの代わりに繊維強化樹脂製シートでなる可撓性シートを矩形の枠に固着して垂れ壁部材を構成し、この垂れ壁部材を、天井に設けたレールに取付けて垂れ壁を構成したものが採用されている。 In order to avoid such troubles when using a glass panel, a flexible sheet made of a fiber reinforced resin sheet is conventionally fixed to a rectangular frame instead of a glass panel to form a hanging wall member. A wall member is attached to a rail provided on the ceiling to constitute a hanging wall.

また、特許文献１に開示された垂れ壁部材のように、可撓性シートを垂れ壁に使用する場合、皺の発生が問題となる。なぜなら、視界を妨げないようにするために、前述のように可撓性シートには透明材料を使用することが好ましいが、透明材料を使用すると、可撓性シートが光の一部を反射させ、可撓性シートの皺が明瞭に目視され、美観を損ねるからである。 Moreover, when using a flexible sheet | seat for a drooping wall like the drooping wall member disclosed by patent document 1, generation | occurrence | production of a wrinkle becomes a problem. This is because, as described above, it is preferable to use a transparent material for the flexible sheet so as not to obstruct the field of view. However, when a transparent material is used, the flexible sheet reflects a part of light. This is because the wrinkles of the flexible sheet are clearly seen and the aesthetic appearance is impaired.

そのような皺の発生を防止することを目的として、この特許文献１の垂れ壁部材においては、シート端部及びコーナー部において、可撓性シートを把持するシート調整機構を設ける。このシート調整機構は、ねじを用いて押さえ部材と受け金具によってシートを把持し、その押さえ部材と受け金具のフレームに対する位置を調整ねじにより調節することにより、可撓性シートに張力を付与する構成を有する。 For the purpose of preventing the occurrence of such wrinkles, the hanging wall member of Patent Document 1 is provided with a sheet adjustment mechanism for gripping a flexible sheet at the sheet end and corner. The sheet adjusting mechanism is configured to grip a sheet with a pressing member and a receiving metal fitting using a screw, and to apply tension to the flexible sheet by adjusting the position of the pressing member and the receiving metal piece with respect to the frame with an adjusting screw.

特許文献１に開示された垂れ壁部材の調整機構では、可撓性シートに張力を付与するための調整機構は、フレームとは別に調整機構のための押さえ部材及び受け金具などの専用の部材を用意する必要があり、部品点数が多くなることから製造費用が高くなると共に、組立工数が多くなるという問題点があった。 In the adjustment mechanism for the hanging wall member disclosed in Patent Document 1, the adjustment mechanism for applying tension to the flexible sheet is a dedicated member such as a pressing member and a receiving bracket for the adjustment mechanism separately from the frame. There is a problem that the number of parts needs to be prepared and the number of parts increases, resulting in an increase in manufacturing cost and an increase in the number of assembly steps.

本発明は、上記問題点に鑑み、可撓性シートの皺を解消することができると共に、部品点数及び組立工数を削減が可能となる構成の防煙用の垂れ壁部材とこれを用いた垂れ壁を提供することを目的とする。 In view of the above-described problems, the present invention is capable of eliminating the wrinkles of the flexible sheet and reducing the number of parts and the number of assembly steps, and a drooping wall member for smoke prevention and a drip using the same. The purpose is to provide a wall.

前記結合ねじは前記調整ねじよりも前記第２の枠材の両端側に位置する
垂れ壁部材である。 The hanging wall member of the present invention is
Frame having a rectangular is constituted by a pair of second frame member that binds to its opposite ends a pair of first frame member,
In hanging wall member that consists in a flexible sheet is adhered to the frame body,
Both ends of the flexible sheet are fixed to the second frame member,
A side between the both ends of the flexible sheet is fixed to a central portion in the longitudinal direction of the first frame member,
The coupling portion between the second frame member and the first frame member, the second being inserted through the screw insertion hole formed in the frame member, said first threaded into the first frame member A coupling screw that fastens the frame member and the second frame member, and an adjustment screw that is screwed into a screw hole provided in the second frame member and presses the tip to the end of the first frame member door is provided,

構成とする。 The hanging wall member of the present invention is more preferably,
It said second frame member is made of a vertical frame, and said first frame member is a long horizontal frame than the vertical frame,
The configuration.

本発明の垂れ壁は、前記垂れ壁部材を用いて構成されたものである。 The drooping wall of the present invention is configured using the dripping wall member.

本発明の垂れ壁部材は、前記第２の枠材に前記可撓性シートの両端が固着され、前記第１の枠材の長手方向の中央部に、前記可撓性シートにおける前記両端の間の辺が固着される。また、第１の枠材の端部と第２の枠材の結合部分に、第２の枠材に挿通し、第１の枠材に設けるねじ孔に螺合する結合ねじと、第２の枠材に設けるねじ孔に螺合し、第１の枠材の端部に先端を圧接させる調整ねじを設けたものである。そして、第１の枠材と第２の枠材の結合部分においては、結合ねじを調整ねじよりも第２の枠材の両端側に位置させたものである。 In the hanging wall member according to the present invention, both ends of the flexible sheet are fixed to the second frame member, and the center of the first frame member in the longitudinal direction is between the both ends of the flexible sheet. The side of is fixed. Further, the end portion and the coupling portion of the second frame member of the first frame member, and inserted into the second frame member, and a coupling screw to be screwed into a screw hole provided in the first frame member, the second An adjustment screw is provided that is screwed into a screw hole provided in the frame member and presses the tip of the first frame member to the end. And in the connection part of a 1st frame material and a 2nd frame material, a connection screw is located in the both ends side of a 2nd frame material rather than an adjustment screw.

このような構成を有するため、調整ねじにより第１の枠材の端部と第２の枠材との間に隙間を持たせた状態にしておき、結合ねじにより、縦枠と横枠の距離を縮める方向に締め付けるか、または調整ねじにより隙間を拡大する方向にねじ込むと、調整ねじが第１の枠材と当接する部分を支点として、第１の枠材と第２の枠材の結合部分を鈍角側に開こうとする力が働く。このため、可撓性シートの皺の発生を防止することが可能となる。また、第１の枠材の端部と第２の枠材との結合部に結合ねじ以外に調整ねじを設けるという簡単な構造で可撓性シートに張力を与えて皺の発生を防止することが可能となる。このため、垂れ壁部材の部品点数及び組立工数を削減できる。 Since it has such a configuration, a gap is provided between the end portion of the first frame member and the second frame member by the adjusting screw, and the distance between the vertical frame and the horizontal frame is set by the coupling screw. If the adjustment screw is tightened in the direction of contracting or screwed in the direction of widening the gap with the adjustment screw, the connecting portion of the first frame material and the second frame material with the adjustment screw contacting the first frame material as a fulcrum The force which tries to open to the obtuse angle side works. For this reason, generation | occurrence | production of the wrinkle of a flexible sheet | seat can be prevented. In addition, a simple structure in which an adjustment screw is provided in addition to the coupling screw at the coupling portion between the end portion of the first frame member and the second frame member to prevent the occurrence of wrinkles by applying tension to the flexible sheet. Is possible. For this reason, the number of parts and the number of assembling steps of the drooping wall member can be reduced.

本発明において、例えば第１の枠材を上枠、下枠とし、第２の枠材を縦枠とすれば、上枠、下枠の端部と縦枠との間に隙間を設け、かつ調整ねじを上枠、下枠に当接した状態で結合ねじを締め込むと、縦枠の中央側が外側方向へ撓もうとし、同時に上枠の中央側は上側に、下枠の中央側は下側に撓もうとする。このため、固着された可撓性シートの左右方向の中央部の上辺、下辺をそれぞれ上枠、下枠に固着すれば、可撓性シートに上下方向にも張力を付与することができる。このため、可撓性シートの上下方向にも張りを持たせることができ、好適に可撓性シートの皺の発生を防止することができる。 In the present invention, for example , if the first frame member is an upper frame and a lower frame, and the second frame member is a vertical frame , a gap is provided between the end of the upper frame and the lower frame and the vertical frame, and When the coupling screw is tightened with the adjustment screw in contact with the upper and lower frames, the center side of the vertical frame will bend outward, and at the same time, the center side of the upper frame will be upward and the center side of the lower frame will be Try to flex to the side. For this reason, if the upper side and the lower side of the central portion in the left-right direction of the fixed flexible sheet are fixed to the upper frame and the lower frame, respectively, tension can be applied to the flexible sheet in the vertical direction. For this reason, tension can be given also to the up-down direction of a flexible sheet, and generation | occurrence | production of the wrinkle of a flexible sheet can be prevented suitably .

また、本発明の垂れ壁部材を用いて垂れ壁を構成することにより、皺の発生がなく外観が優れ、かつ垂れ壁部材の部品点数と組立工数の削減が可能となる垂れ壁を提供することが可能となる。 Also, by providing a hanging wall by using the hanging wall member of the present invention, it is possible to provide a hanging wall that has no appearance of wrinkles and has an excellent appearance, and can reduce the number of parts and the number of assembly steps of the hanging wall member. Is possible.

図６（Ａ）及び図７に示すように、上部取付け枠４は天井２に当接させてタッピングねじ等の固定具５により固定する横板部４ａと、その両側に一体に形成した縦板部４ｂ，４ｃとを有し、略逆Ｕ字形の断面形状をなす。これらの縦板部４ｂ，４ｃの内面には、内方に突出した水平部４ｘと上方に突出した垂直部４ｙとを備えた上枠支持部４ｄ，４ｅを形成する。 As shown in FIGS. 6 (A) and 7, the upper mounting frame 4 is in contact with the ceiling 2 and fixed by a fixing tool 5 such as a tapping screw, and a vertical plate integrally formed on both sides thereof. And has a substantially inverted U-shaped cross-sectional shape. Upper frame support portions 4d and 4e having a horizontal portion 4x projecting inward and a vertical portion 4y projecting upward are formed on the inner surfaces of the vertical plate portions 4b and 4c.

上枠１１は、図７に示すように、本実施の形態において結合ねじ１８として用いるタッピングねじを螺合するタッピングホール１１ａ（図１０（Ａ）参照）と、調整ねじ１７の先端を圧接するための肉厚部１１ｈとを有する。また、上枠１１の上部には、上部取付け枠４の上枠支持部４ｄ（または４ｅ）に係止するための係止部１１ｂを有する。この係止部１１ｂは、タッピングホール１１ａの形成面の片側近傍から上方に突出した縦板部１１ｃと、この縦板部１１ｃから上方に斜めに傾けて形成した傾斜部１１ｅと、この傾斜部１１ｅに連続して形成した水平部１１ｆと、この水平部１１ｆから下向きに形成した係止片１１ｇとからなる。 As shown in FIG. 7, the upper frame 11 presses the tapping hole 11 a (see FIG. 10A) into which the tapping screw used as the coupling screw 18 in the present embodiment is screwed with the tip of the adjustment screw 17. And a thick portion 11h. In addition, an upper portion of the upper frame 11 has an engaging portion 11b for engaging with the upper frame support portion 4d (or 4e) of the upper mounting frame 4. The locking portion 11b includes a vertical plate portion 11c that protrudes upward from near one side of the surface on which the tapping hole 11a is formed, an inclined portion 11e that is formed obliquely upward from the vertical plate portion 11c, and the inclined portion 11e. The horizontal portion 11f is formed continuously with the horizontal portion 11f, and the locking piece 11g is formed downward from the horizontal portion 11f.

図８に示すように、上部取付け枠４に垂れ壁部材１を取付ける際には、上枠１１を上部取付け枠４内に入れ、上枠１１の側板部１１ｉ、１１ｊの内、係止片１１ｇの反対側の側板部１１ｉを縦板部４ｃの内側に近づけた状態で、矢印３０で示すように持ち上げる。この持ち上げにより、係止部１１ｂの傾斜部１１ｅが上枠支持部４ｅに当接して摺動し、上枠１１の上昇にともなって上枠１１が矢印３１で示すように縦板部４ｂ側（図８における左側）へとガイドされ、側板部１１ｉの上端が上枠支持部４ｅの下面に当接すると、上枠１１の上昇が止められる。この状態では、係止片１１ｇが上枠支持部４ｄにおける垂直部４ｙと縦板部４ｂとの間に位置する。この状態から垂れ壁部材１を下ろすことにより、係止部１１ｂが上枠支持部４ｄに係止される。この傾斜部１１ｅと上枠支持部４ｅによるガイド機構によって、取付け作業者が図８の左右方向における上枠１１の位置を特別に注意せずとも、容易に上部取付け枠４に垂れ壁部材１を取付けることができる。 As shown in FIG. 8, when the hanging wall member 1 is attached to the upper mounting frame 4, the upper frame 11 is placed in the upper mounting frame 4, and the locking pieces 11g of the side plate portions 11i and 11j of the upper frame 11 are placed. The side plate 11i on the opposite side is lifted as indicated by the arrow 30 in a state where the side plate 11i is close to the inside of the vertical plate 4c. By this lifting, the inclined portion 11 e of the locking portion 11 b slides in contact with the upper frame support portion 4 e, and as the upper frame 11 rises, the upper frame 11 is on the side of the vertical plate portion 4 b (as indicated by an arrow 31). When the upper end of the side plate portion 11i comes into contact with the lower surface of the upper frame support portion 4e, the upper frame 11 is prevented from rising. In this state, the locking piece 11g is located between the vertical portion 4y and the vertical plate portion 4b in the upper frame support portion 4d. By lowering the hanging wall member 1 from this state, the locking portion 11b is locked to the upper frame support portion 4d. By the guide mechanism by the inclined portion 11e and the upper frame support portion 4e, the installation worker can easily attach the hanging wall member 1 to the upper mounting frame 4 without paying special attention to the position of the upper frame 11 in the left-right direction in FIG. Can be installed.

ここで、上部取付け枠４の縦板部４ｂ，４ｃに上枠支持部４ｄ，４ｅを対称形に設けているため、図６（Ａ）における垂れ壁部材１の方向を逆にして上枠支持部４ｅに係止片１１ｇを係止するようにして、傾斜部１１ｅが上枠支持部４ｄと当接するガイド機構を構成することも可能である。このため、天井２に上部取付け枠４を取付ける際にその向きを意識しなくてもよいため、取付けにおける作業性が向上する。 Here, since the upper frame support portions 4d and 4e are provided symmetrically on the vertical plate portions 4b and 4c of the upper mounting frame 4, the direction of the hanging wall member 1 in FIG. It is also possible to configure a guide mechanism in which the inclined portion 11e contacts the upper frame support portion 4d so that the locking piece 11g is locked to the portion 4e. For this reason, when attaching the upper mounting frame 4 to the ceiling 2, it is not necessary to be aware of its orientation, so that workability in mounting is improved.

側部取付け枠６は図９（Ａ）、（Ｃ）に示すように、横断面形状が略コ字形をなし、その開口幅Ｗ１を、垂れ壁部材１の上枠１１、縦枠１２及び下枠１３の可撓性シート２１を含めた見込み面の面外方向の幅Ｗ２（図９（Ｂ）参照）よりわずかに広く形成することにより、側部取付け枠６に上枠１１、縦枠１２、下枠１３を内嵌可能な構造を有する。 As shown in FIGS. 9 (A) and 9 (C), the side mounting frame 6 has a substantially U-shaped cross section, and its opening width W1 is set to the upper frame 11, the vertical frame 12 and the lower frame of the hanging wall member 1. By forming the frame 13 slightly wider than the width W2 in the out-of-plane direction of the prospective surface including the flexible sheet 21 (see FIG. 9B), the upper frame 11 and the vertical frame 12 are formed on the side attachment frame 6. The lower frame 13 can be fitted inside.

また、中継枠８は、図９（Ａ）、（Ｄ）に示すように、表裏の縦板部８ａ，８ｂの間に結合板部８ｃを一体に形成した略Ｈ字形の断面形状を有する。そしてこれらの縦板部８ａ，８ｂと結合板部８ｃで形成される２つのコ字形をなす部分を縦枠１２を内嵌する嵌合部８ｄ，８ｅとする。これらの嵌合部８ｄ，８ｅの開口幅Ｗ１も側部取付け枠６の開口幅Ｗ１と同様であり、嵌合部８ｄ，８ｅに上枠１１、縦枠１２、下枠１３を内嵌可能な構造を有する。 Further, as shown in FIGS. 9A and 9D, the relay frame 8 has a substantially H-shaped cross-sectional shape in which a coupling plate portion 8c is integrally formed between front and back vertical plate portions 8a and 8b. The two U-shaped portions formed by the vertical plate portions 8a and 8b and the coupling plate portion 8c are set as fitting portions 8d and 8e in which the vertical frame 12 is fitted. The opening width W1 of these fitting portions 8d and 8e is the same as the opening width W1 of the side portion mounting frame 6, and the upper frame 11, the vertical frame 12, and the lower frame 13 can be fitted into the fitting portions 8d and 8e. It has a structure.

また、一方の嵌合部８ｅの見付け面の面内方向の幅Ｗ３は、他方の嵌合部８ｄの幅Ｗ４より広く形成する。これにより、図９（Ａ）に示すように、嵌合部８ｄ，８ｅに隣接する垂れ壁部材１，１の縦枠１２，１２をそれぞれ嵌合して垂れ壁部材１，１を取付けた場合、一方の嵌合部８ｅに、中継枠８の上端を上部取付け枠４に取付けるためのタッピングねじ等の固定具２４（図２、図６、図７参照）の収容スペースや、下部カバー９を中継枠８に取付けるためのタッピングねじ等の固定具２５の収容スペースを形成する。 Further, the width W3 in the in-plane direction of the finding surface of one fitting portion 8e is formed wider than the width W4 of the other fitting portion 8d. Accordingly, as shown in FIG. 9A, when the vertical wall members 1 and 1 of the hanging wall members 1 and 1 adjacent to the fitting portions 8d and 8e are respectively fitted and the hanging wall members 1 and 1 are attached. In one fitting portion 8e, a storage space for a fixing tool 24 such as a tapping screw for attaching the upper end of the relay frame 8 to the upper mounting frame 4 (see FIGS. 2, 6, and 7) and a lower cover 9 are provided. An accommodation space for a fixing tool 25 such as a tapping screw to be attached to the relay frame 8 is formed.

図９（Ｄ）において、中継枠８の見込み面の面外方向の幅Ｗ５は、上部取付け枠４の縦板部４ｂ，４ｃ間の幅Ｗ６（図７参照）よりわずかに狭く形成することにより、中継枠８はその上端部を上部取付け枠４内に嵌め込むことができるように構成する。また、上部取付け枠４の縦板部４ｂ，４ｃの内面に設けた上枠支持部４ｄ，４ｅは、中継枠８の上端を当接させるストッパとなる。 9D, the width W5 in the out-of-plane direction of the prospective surface of the relay frame 8 is slightly narrower than the width W6 between the vertical plate portions 4b and 4c of the upper mounting frame 4 (see FIG. 7). The relay frame 8 is configured such that its upper end can be fitted into the upper mounting frame 4. Further, the upper frame support portions 4 d and 4 e provided on the inner surfaces of the vertical plate portions 4 b and 4 c of the upper mounting frame 4 serve as stoppers for contacting the upper end of the relay frame 8.

図６（Ａ）において、垂れ壁部材１の下部には、可撓性シート２１を固着した下枠１３と、その下枠１３に取付けられるカバー取付けピース１４とが設けられる。また、下枠１３、中継枠８の下部、及び側部取付け枠６の下部を内嵌して下部カバー９が設けられる。 In FIG. 6A, a lower frame 13 to which a flexible sheet 21 is fixed and a cover attachment piece 14 attached to the lower frame 13 are provided at the lower part of the hanging wall member 1. A lower cover 9 is provided by fitting the lower frame 13, the lower part of the relay frame 8, and the lower part of the side attachment frame 6.

カバー取付けピース１４は、下枠１３の下部のガイド溝１３ｂ，１３ｃに突出部１４ｂ，１４ｂをスライド可能に嵌め込んで取付けられる。図６（Ｂ）に示すように、下部カバー９は、略Ｕ字形に形成される。この下部カバー９の内部見込み面の間隔Ｗ７は中継枠８の見込み面の面外方向の幅Ｗ５（図９（Ｄ）参照）よりわずかに広く形成することにより、中継枠８に下部カバー９を内嵌可能に構成する。側部取付け枠６も上部取付け枠４や下部カバー９に内嵌可能な形状を有する。 The cover attaching piece 14 is attached by fitting the projecting portions 14b, 14b into the guide grooves 13b, 13c below the lower frame 13 so as to be slidable. As shown in FIG. 6B, the lower cover 9 is formed in a substantially U shape. The gap W7 between the inner prospective surfaces of the lower cover 9 is slightly wider than the width W5 of the prospective surface of the relay frame 8 in the out-of-plane direction (see FIG. 9D), so that the lower cover 9 is attached to the relay frame 8. It is configured to be able to fit inside. The side mounting frame 6 also has a shape that can be fitted into the upper mounting frame 4 and the lower cover 9.

この下部カバー９の内側には、互いに対向するように突出させた係止片９ａ，９ｂが形成される。下部カバー９は、下枠１３の下部から押し嵌めすることにより、カバー取付けピースの支持片１４ｃ，１４ｄに下部カバー９の係止片９ａ，９ｂが乗り越えて係止片９ａ，９ｂを支持片１４ｃ，１４ｄ上に係止させることにより、下部カバー９をカバー取付けピース１４で支持させて取付け、固定具２５により下部カバー９を中継枠８に固定する。詳しくは、カバー取付けピース１４の支持片１４ｃ，１４ｄの先端部の最大幅は、下枠１３の幅より大きく、かつ下部カバー９の係止片９ａ，９ｂ間の幅より大きくすることにより、下部カバー９の係止片９ａ，９ｂをカバー取付けピース１４の支持片１４ｃ，１４ｄに係止させることを可能としている。 Locking pieces 9 a and 9 b are formed on the inner side of the lower cover 9 so as to protrude so as to face each other. The lower cover 9 is press-fitted from the lower part of the lower frame 13, so that the locking pieces 9a and 9b of the lower cover 9 get over the supporting pieces 14c and 14d of the cover mounting piece, and the locking pieces 9a and 9b are supported by the supporting pieces 14c. , 14d, the lower cover 9 is supported and attached by the cover attachment piece 14, and the lower cover 9 is fixed to the relay frame 8 by the fixture 25. Specifically, the maximum width of the front end portions of the support pieces 14c, 14d of the cover mounting piece 14 is larger than the width of the lower frame 13 and larger than the width between the locking pieces 9a, 9b of the lower cover 9, thereby lowering the lower portion. The locking pieces 9 a and 9 b of the cover 9 can be locked to the support pieces 14 c and 14 d of the cover mounting piece 14.

また、上枠１１の係止部１１ｂを上部取付け枠４の上枠支持部４ｅに係止して垂れ壁部材１を取付けた状態において、上枠１１と上部取付け枠４の縦板部４ｂ，４ｃとの間に隙間が形成されるように構成する。これにより、垂れ壁部材１を上部取付け枠４に支持させて取付けた状態において、隣接する垂れ壁部材１，１間に中継枠８を下から縦枠１２，１２間に挿入する際に、中継枠８の縦板部８ａ，８ｂの上端部が上部取付け枠４の縦板部４ｂ，４ｃと縦枠１２の間に嵌まり、中継枠８の上端部を内側上部取付け枠４内に挿入可能とする。 Further, in a state where the hanging wall member 1 is attached by engaging the engaging portion 11b of the upper frame 11 with the upper frame supporting portion 4e of the upper attaching frame 4, the vertical plate portions 4b of the upper frame 11 and the upper attaching frame 4 are provided. It is configured such that a gap is formed between 4c. Accordingly, when the hanging wall member 1 is supported and attached to the upper mounting frame 4, the relay frame 8 is inserted between the adjacent hanging wall members 1 and 1 between the vertical frames 12 and 12 from below. The upper end portions of the vertical plate portions 8a, 8b of the frame 8 fit between the vertical plate portions 4b, 4c of the upper mounting frame 4 and the vertical frame 12, and the upper end portion of the relay frame 8 can be inserted into the inner upper mounting frame 4. And

FIG. 10 (A) shows an adjustment mechanism 19A provided at the joint between the vertical frame 12 and the left end of the upper frame 11 in FIG. Further, FIG. 10B shows an adjusting mechanism 19B provided at a joint portion between the vertical frame 12 and the left end portion of the lower frame 13 in FIG.

図５（Ｂ）、（Ｃ）および図６（Ａ）に示すように、上枠１１においては、タッピングねじからなる結合ねじ１８を螺合するタッピングホール１１ａは、調整ねじ１７を当接させる肉厚部１１ｈより上側に設ける。反対に下枠１３のタッピングホール１３ａは肉厚部１３ｄより下側に設ける。 As shown in FIGS. 5 (B), 5 (C) and 6 (A), in the upper frame 11, the tapping hole 11a into which the coupling screw 18 made of a tapping screw is screwed is a meat that makes the adjustment screw 17 contact. Provided above the thick part 11h. On the contrary, the tapping hole 13a of the lower frame 13 is provided below the thick portion 13d.

図５（Ｄ）に示すように、縦枠１２として、下枠１３と同じ型枠を用いており、タッピングホール１２ａを有すると共に、縦板部１２ｄに肉厚部１２ｅを有する。図１０（Ａ）、（Ｂ）に示すように、タッピングホール１２ａと肉厚部１２ｅにこれらに直交する方向にねじ挿通孔１２ｂやねじ孔１２ｃを設ける。図１０（Ａ）に示す上部結合部おいては、結合ねじ１８は、縦枠１２におけるねじ孔１２ｃより上側に設けられたねじ挿通孔１２ｂに挿通されるとともに、上枠１１のタッピングホール１１ａに食い込ませて螺合する。調整ねじ１７は、縦枠１２におけるねじ挿通孔１２ｂより下側に設けられたねじ孔１２ｃに螺合し、その先端を上枠１１の端部の底部に設けられた肉厚部１１ｈに当接させる。 As shown in FIG. 5D, the same frame as the lower frame 13 is used as the vertical frame 12, and has a tapping hole 12a and a thick portion 12e in the vertical plate portion 12d. As shown in FIGS. 10A and 10B, the screw insertion hole 12b and the screw hole 12c are provided in the tapping hole 12a and the thick portion 12e in a direction perpendicular to them. In the upper coupling portion shown in FIG. 10A, the coupling screw 18 is inserted into the screw insertion hole 12b provided above the screw hole 12c in the vertical frame 12, and into the tapping hole 11a of the upper frame 11. Engage and screw. The adjustment screw 17 is screwed into a screw hole 12 c provided below the screw insertion hole 12 b in the vertical frame 12, and its tip abuts on a thick portion 11 h provided at the bottom of the end of the upper frame 11. Let

図１０（Ｂ）に示す下部結合部においては、結合ねじ１８は、縦枠１２におけるねじ孔１２ｃより下側に設けられたねじ挿通孔１２ｂに挿通されるとともに、下枠１３のタッピングホール１３ａに食い込ませて螺合する。調整ねじ１７は、縦枠１２におけるねじ挿通孔１２ｂより上側に設けられたねじ孔１２ｃに螺合し、その先端を下枠１３の端部の上部に設けた肉厚部１３ｄに当接させる。 In the lower coupling portion shown in FIG. 10 (B), the coupling screw 18 is inserted into a screw insertion hole 12b provided below the screw hole 12c in the vertical frame 12, and into the tapping hole 13a of the lower frame 13. Engage and screw. The adjustment screw 17 is screwed into a screw hole 12 c provided above the screw insertion hole 12 b in the vertical frame 12, and a tip thereof is brought into contact with a thick portion 13 d provided at an upper portion of the end portion of the lower frame 13.

本実施の形態の垂れ壁部材１の製作は次の工程により行なう。垂れ壁部材１として、これを中継枠８を介して複数枚のものを躯体３，３間に取付ける場合、垂れ壁部材１のトータルの長さが側部取付け枠６，６間の幅に合うように予め枠体１０の寸法を設計しておく。枠体１０の組立は、まず、図３に示すように、上枠１１、下枠１３の両端に縦枠１２の上端部、下端部を結合ねじ１８によって結合する。また、調整ねじ１７を縦枠１２に設けたねじ孔１２ｃに螺合して取付けておく。なおこの調整ねじ１７の取付けは、可撓性シート２１を枠体１０に固着した後でもよい。また、図４に示す可撓性シート２１の固着部２２，２３ａ，２３ｂに設ける両面粘着テープの粘着あるいは接着剤の塗着は、枠体１０の組立前または組立後に行なう。 The hanging wall member 1 according to the present embodiment is manufactured by the following steps. When a plurality of the hanging wall members 1 are attached between the housings 3 and 3 via the relay frame 8 as the hanging wall member 1, the total length of the hanging wall member 1 matches the width between the side attachment frames 6 and 6. Thus, the dimensions of the frame 10 are designed in advance. As shown in FIG. 3, first, the frame 10 is assembled by connecting the upper and lower ends of the vertical frame 12 to both ends of the upper frame 11 and the lower frame 13 with connecting screws 18. The adjusting screw 17 is screwed into a screw hole 12c provided in the vertical frame 12 and attached. The adjustment screw 17 may be attached after the flexible sheet 21 is fixed to the frame 10. Further, the adhesive or adhesive application of the double-sided adhesive tape provided on the adhering portions 22, 23a, 23b of the flexible sheet 21 shown in FIG. 4 is performed before or after the frame body 10 is assembled.

このように固着部２２，２３ａ，２３ｂに設ける両面粘着テープあるいは接着剤を施した枠体１０をプレス台上に載せ、可撓性シート２１を枠体１０に圧力を加えて固着する。その後、可撓性シート２１が枠体１０からはみ出した部分をカットする。また、ビス等の固定具２６，２７（図２参照）の固定は、その後に行なう。 In this way, the frame 10 with the double-sided adhesive tape or adhesive provided on the fixing portions 22, 23a, 23b is placed on the press stand, and the flexible sheet 21 is fixed to the frame 10 by applying pressure. Thereafter, the portion where the flexible sheet 21 protrudes from the frame body 10 is cut. Further, the fixing tools 26 and 27 (see FIG. 2) such as screws are fixed thereafter.

次に調整機構１９Ａ，１９Ｂによる可撓性シート２１の張力調整手順について説明する。図１１（Ａ）〜（Ｃ）は調整機構１９Ａ，１９Ｂによる調整手順を説明する図である。図１１（Ａ）は、垂れ壁部材１を組み立てた後の状態を示す。この組み立てた後の状態は、上枠１１及び下枠１３の端部に縦枠１２を当接させた状態である。この状態から、縦枠１２が上枠１１及び下枠１３から離れる方向に結合ねじ１８を回す。これにより、縦枠１２と上枠１１及び下枠１３との間に隙間が生じる。その後、図１１（Ｂ）に示すように、調整ねじ１７を回してその先端を上枠１１及び下枠１３に当接させて、隙間を保持する。 Next, a procedure for adjusting the tension of the flexible sheet 21 by the adjusting mechanisms 19A and 19B will be described. FIGS. 11A to 11C are diagrams for explaining the adjustment procedure by the adjustment mechanisms 19A and 19B. FIG. 11A shows a state after the hanging wall member 1 is assembled. This assembled state is a state in which the vertical frame 12 is brought into contact with the end portions of the upper frame 11 and the lower frame 13. From this state, the coupling screw 18 is rotated in a direction in which the vertical frame 12 is separated from the upper frame 11 and the lower frame 13. Thereby, a gap is generated between the vertical frame 12 and the upper and lower frames 11 and 13. Thereafter, as shown in FIG. 11 (B), the adjustment screw 17 is turned so that the tips thereof are brought into contact with the upper frame 11 and the lower frame 13 to hold the gap.

次に、図１１（Ｂ）の状態から、結合ねじ１８を締め付ける方向に回転させる。このように結合ねじ１８を回転させると、結合ねじ１８により縦枠１２を上枠１１、下枠１３に引きつけようとする力が生じる。これにより、調整ねじ１７と上枠１１と下枠１３との当接部分３２，３３において、調整ねじ１７の先端が上枠１１と下枠１３に圧接する。このため、縦枠１２には、当接部分３２，３３を支点とし、結合ねじ１８から縦枠１２が受ける力を力点としたテコの力が生じ、図１１（Ｃ）に示すように、縦枠１２と上枠１１、下枠１３との間のなす角が直角から鈍角に開こうとする力Ｆ１，Ｆ２が生じる。 Next, from the state of FIG. 11 (B), the coupling screw 18 is rotated in the tightening direction. When the coupling screw 18 is rotated in this way, a force for attracting the vertical frame 12 to the upper frame 11 and the lower frame 13 is generated by the coupling screw 18. As a result, at the contact portions 32 and 33 of the adjustment screw 17, the upper frame 11, and the lower frame 13, the tip of the adjustment screw 17 comes into pressure contact with the upper frame 11 and the lower frame 13. For this reason, the vertical frame 12 generates a lever force with the contact portions 32 and 33 as fulcrums and the force received by the vertical frame 12 from the coupling screw 18 as a force point. As shown in FIG. Forces F1 and F2 are generated in which the angle formed between the frame 12, the upper frame 11, and the lower frame 13 tries to open from a right angle to an obtuse angle.

また、図１１（Ｂ）の状態から、結合ねじ１８ではなく、調整ねじ１７を上枠１１及び下枠１３の当接方向に回転させてねじ込んでも、上述した結合ねじ１８を締め付けた場合と同様の作用が得られる。このように、上枠１１及び下枠１３と縦枠１２との間に一定の隙間を保持させた後は、結合ねじ１８の締め付けまたは調整ねじ１７のねじ込みのどちらでも可撓性シート２１に張力を付与する効果が得られる。 Further, from the state of FIG. 11B, even if the adjusting screw 17 is rotated in the contact direction of the upper frame 11 and the lower frame 13 instead of the connecting screw 18 and screwed in, it is the same as the case where the connecting screw 18 is tightened. Is obtained. As described above, after a certain gap is maintained between the upper frame 11 and the lower frame 13 and the vertical frame 12, either the tightening of the coupling screw 18 or the screwing of the adjusting screw 17 causes tension on the flexible sheet 21. The effect of imparting is obtained.

このように調整機構１９Ａ，１９Ｂによる調整作業がなされることで、図１１（Ｂ）のように、縦枠１２の中央部が外方向に撓むため、縦枠１２により固着された可撓性シート２１をさらに横方向に引っ張り、可撓性シート２１に横方向にさらに張力を与えることができる。その結果、皺の発生を防止することができる。また、このような間隔調整作業は、高所作業を要せず、垂れ壁部材１を例えば作業台上に載置した状態で行なうことができるので、皺伸ばし作業を容易に行なうことができる。 By performing the adjustment work by the adjustment mechanisms 19A and 19B in this way, the central portion of the vertical frame 12 bends outward as shown in FIG. 11B, so that the flexibility fixed by the vertical frame 12 is secured. The sheet 21 can be further pulled in the lateral direction, and further tension can be applied to the flexible sheet 21 in the lateral direction. As a result, generation of wrinkles can be prevented. In addition, such an interval adjustment operation does not require an altitude work, and can be performed in a state where the hanging wall member 1 is placed on, for example, a workbench, so that the heel stretching operation can be easily performed.

また、本実施の形態においては、上枠１１の中央部及び下枠１３の中央部に可撓性シート２１が固着されているので、上枠１１の中央部が上側に撓み、かつ下枠１３の中央部が下側に撓むことにより、可撓性シートの上下方向についても張力が付与される。このため、調整機構１９Ａ，１９Ｂによって、可撓性シート２１に左右、上下方向に張力を与えられ、皺の発生をさらに確実に防止することができる。 In the present embodiment, since the flexible sheet 21 is fixed to the central portion of the upper frame 11 and the central portion of the lower frame 13, the central portion of the upper frame 11 bends upward and the lower frame 13. When the central part of the flexible sheet is bent downward, tension is applied also in the vertical direction of the flexible sheet. For this reason, tension can be given to the flexible sheet 21 in the left and right and up and down directions by the adjusting mechanisms 19A and 19B, and the generation of wrinkles can be prevented more reliably.

また、本実施形態においては縦枠１２が直接可撓性シート２１に張力を与えることから、調整ねじ１７と結合ねじ１８からなる簡単な構造で可撓性シート２１の張力を調整し、皺の発生を防止することが可能となる。 In this embodiment, since the vertical frame 12 directly applies tension to the flexible sheet 21, the tension of the flexible sheet 21 is adjusted with a simple structure including the adjusting screw 17 and the coupling screw 18, and Occurrence can be prevented.

このように、本実施の形態においては、上枠１１、下枠１３の端部と縦枠１２との結合部に結合ねじ１８以外に調整ねじ１７を設けるという簡単な構造で可撓性シート２１に張力を与えて皺の発生を防止することが可能となる。このため、垂れ壁部材の部品点数及び組立工数を削減できる。 As described above, in the present embodiment, the flexible sheet 21 has a simple structure in which the adjustment screw 17 is provided in addition to the coupling screw 18 at the coupling portion between the end portions of the upper frame 11 and the lower frame 13 and the vertical frame 12. It is possible to prevent the generation of wrinkles by applying tension to the wire. For this reason, the number of parts and the number of assembling steps of the drooping wall member can be reduced.

このようにして製作した垂れ壁部材１を、予め天井２と躯体３に取付けられている上部取付け枠４と側部取付け枠６に取付けて垂れ壁を構成する。この取付けに際し、図８で説明したように、上部取付け枠４内に上枠１１を下から挿入し、上枠１１の係止部１１ｂを上枠支持部４ｄに係止させる。その後、側部取付け枠６側の垂れ壁部材１については、垂れ壁部材１を側部取付け枠６側にスライドさせ、図９（Ａ）に示すように、側部取付け枠６に垂れ壁部材１の縦枠１２を内嵌する。 The hanging wall member 1 manufactured in this way is attached to an upper mounting frame 4 and a side mounting frame 6 that are previously mounted on the ceiling 2 and the housing 3 to form a hanging wall. In this attachment, as described with reference to FIG. 8, the upper frame 11 is inserted into the upper attachment frame 4 from below, and the locking portion 11b of the upper frame 11 is locked to the upper frame support portion 4d. Thereafter, with respect to the hanging wall member 1 on the side portion mounting frame 6 side, the hanging wall member 1 is slid to the side portion mounting frame 6 side, and as shown in FIG. One vertical frame 12 is fitted inside.

このように、施工箇所に設けるすべての垂れ壁部材１を取付け枠４，６に取付けた後、隣接する垂れ壁部材１，１の縦枠１２，１２間に中継枠８を下側から挿入する。ここで、図９（Ｄ）について説明したように、中継枠８の一方の嵌合部８ｅの見付け面の面内方向の幅Ｗ３を、他方の嵌合部８ｄの幅Ｗ４より広く形成している。このため、一方（図９（Ａ）における右側）の垂れ壁部材１の縦枠１２については、この縦枠１２の縦板部１２ｄを、中継枠８の嵌合部８ｅの開口端に揃えた状態において、縦枠１２と結合板部８ｃとの間に固定具２４を収容するスペースが形成される。他方（図９（Ａ）の左側）の垂れ壁部材１の縦枠１２については、この縦枠１２の縦板部１２ｄを、中継枠８の嵌合部８ｄの開口端に揃えた状態において、縦枠１２は中継枠８の結合板部８ｃに当接させた状態で縦枠１２が嵌合部８ｄに嵌合される。 Thus, after attaching all the hanging wall members 1 provided at the construction site to the attachment frames 4 and 6, the relay frame 8 is inserted between the vertical frames 12 and 12 of the adjacent hanging wall members 1 and 1 from the lower side. . Here, as described with reference to FIG. 9D, the width W3 in the in-plane direction of the finding surface of one fitting portion 8e of the relay frame 8 is formed wider than the width W4 of the other fitting portion 8d. Yes. For this reason, with respect to the vertical frame 12 of the hanging wall member 1 on one side (the right side in FIG. 9A), the vertical plate portion 12d of the vertical frame 12 is aligned with the opening end of the fitting portion 8e of the relay frame 8. In the state, a space for accommodating the fixture 24 is formed between the vertical frame 12 and the coupling plate portion 8c. For the vertical frame 12 of the hanging wall member 1 on the other side (left side in FIG. 9A), the vertical plate portion 12d of the vertical frame 12 is aligned with the opening end of the fitting portion 8d of the relay frame 8. The vertical frame 12 is fitted into the fitting portion 8d in a state where the vertical frame 12 is in contact with the coupling plate portion 8c of the relay frame 8.

このように、中継枠８を縦枠１２，１２間に嵌め、かつ中継枠８の上端部を図５に示した上部取付け枠４の上枠支持部４ｄ，４ｅに当接させた状態において、図２、図６（Ａ）、図７に示すように、固定具２４により中継枠８の上端部を上部取付け枠４に固定する。 Thus, in a state where the relay frame 8 is fitted between the vertical frames 12 and 12 and the upper end portion of the relay frame 8 is brought into contact with the upper frame support portions 4d and 4e of the upper mounting frame 4 shown in FIG. As shown in FIGS. 2, 6 </ b> A, and 7, the upper end of the relay frame 8 is fixed to the upper mounting frame 4 by the fixture 24.
