Description

【０００１】
【発明の属する技術分野】
本発明は、複合間仕切壁の上部取付構造に関する。
【０００２】
【従来の技術】
従来の複合間仕切板の上部取付構造としては、例えば、実公昭５５−１６００８号公報に記載される技術が知られている。
【０００３】
図４を用いて、この従来工法を簡単に説明すると、以下の通りとなる。図４（ａ）は、同工法により構築された複合間仕切壁の側断面図であり、図４（ｂ）は、同複合間仕切壁の平断面図である。
【０００４】
すなわち、従来の複合間仕切壁は、建物の構造体である天井４、及び床５のそれぞれに、ランナー２、２を対向させて配置し、これを釘等の留金具６によって固定する。そして、石膏ボードをその表面に形成したＶ溝に沿って折り曲げて形成した、断面口型となる中空パネル７を、スペーサ１３を介在させながらランナー２、２間に建て込んでいく。上部中空パネル７位置に配置されたスペーサ１３は、配置位置を保持するために、ランナー２にタイトに固定される。
【０００５】
この際、複数の中空パネル７は、交互に壁の厚さ方向の一方にずらして、千鳥状に配置していき、その間にシート状の繊維質材料８を、中空パネル７の間を蛇行させて配置していく。このように配置した中空パネル７、繊維質材料８の両側にはボード１１、１２を２重に張りつけている。
【０００６】
【発明が解決しようとする課題】
しかしながら、上記した従来技術では、繊維質材料８、中空パネル７の上部がスペーサ１３により、タイトで動きにくく、これに伴って中空パネル７、及び繊維質材料８は壁の面方向に動く自由度がないため、地震の際、または交通振動によっても、建物の構造体が変形すると、その慣性力等により、複合間仕切壁の上部構造に力が集中し、この部分が破壊される可能性があった。
【０００７】
そこで本発明は、地震や交通振動で建物の構造体が変形しても、複合間仕切壁とランナーとの間で両者の移動を許容し、この上部取付構造が破損しにくい構造を提案することを目的とする。
【０００８】
【課題を解決するための手段】
本発明は、ＡＬＣ板，押出し成形板，ＰＣ板の中から選択された非圧縮性壁材とグラスウール，ロックウール，セラミックファイバーブランケットの中から選択された圧縮性壁材とを重ね合せると共に非圧縮性壁材と圧縮性壁材とが互い違いになるように配置されてなる複合間仕切壁の上部を建物の構造体下面に取り付ける構造において、前記建物の構造体下面に取り付けられ、前記複合間仕切壁の厚さの幅の天板と両側板を有し、断面コ字状となったランナーと、内側に前記圧縮性壁材の上部を収容して、非圧縮性壁材の上部に固定され、前記ランナーの天板の幅から非圧縮性壁材の厚さ分を差し引いた幅の天板と両側板を有する、断面コ字状となったスライドスペーサとからなり、前記非圧縮性壁材の上部と、前記スライドスペーサとが、前記ランナーの内側に、スライド可能に支持されていることを特徴とする複合間仕切壁の上部取付構造を構成して上記課題を解決している。
【０００９】
また、前記ランナーの側板の内面と、前記スライドスペーサの側板の外面との間に摩擦係数の小さい滑り部材を介在させる構造とすることもできる。
【００１０】
【発明の実施の形態】
本発明の実施例を図１乃至図３に基づいて説明する。本実施例は、非圧縮性壁材と、圧縮性壁材とからなる複合間仕切壁を、上階床スラブ下面（天井）と下階床スラブとの間に配置する構造について説明する。図１は複合間仕切壁を建物の上階床スラブ及び下階床スラブ間に取り付けた部分断面斜視図であり、図２は複合間仕切壁の取り付け構造を示す上部の側断面図である。また、図３は、図２のＡ−Ａ線における複合間仕切壁の平断面図である。
【００１１】
図１に示すように、複合間仕切壁１は、圧縮性壁材８と非圧縮性壁材７とを重ね合わせると共に非圧縮性壁材７と圧縮性壁材８とが互い違いになるように配置されて形成される。圧縮性壁材８は、その材料としてグラスウール、ロックウール、セラミックファイバーブランケット等によって構成される。また、非圧縮性壁材７としては、ＡＬＣ板、押出し成形板、ＰＣ板等が使用される。
【００１２】
建物の構造体である上階床スラブの下面４には、長尺の金属製レールである上部ランナー２を釘等の留金具６等を用いて固定している。図１及び図２に示すように、上部ランナー２は、所定の幅を有する天板２ａと、幅方向の両側縁が立ち上がった側板２ｂ、２ｂとから構成され、断面コ字状となっている。両側に側板２ｂ、２ｂが立ち上がった天板２ａの内面は、非圧縮性壁材７の厚さと、後述するスライドスペーサ９の幅とを合わせた幅を有する。
【００１３】
また、下階床スラブ５の上面には、やはり長尺の金属製レールである下部ランナー３を、図示しない釘を用いて固定している。図１に示すように、下部ランナー３は、板体３ａとその一方の側縁が立ち上がった側板３ｂとによって構成される。
【００１４】
非圧縮性壁材７の上部側面には、圧縮性壁材８を取り付けるための空間を保持するスライドスペーサ９を固定している。スライドスペーサ９は、天板９ａと、両側縁が立ち上がった側板９b1、９b2とを有し、断面コ字状となった金具である。一方の側板９b1は、他方の側板９b2に比べて長く、同側板９b1を非圧縮性壁材７の側面に、釘やビス、ボルトやステープル等の留金具１０を用いて止めつけている。スライドスペーサ９の両側板９b1、９b2間の幅は、圧縮性壁材８の幅と略同じ幅か、若しくは若干狭い幅を有する。なお、側板９b1、９b2の間の幅を圧縮性壁材８の幅より大きくし、圧縮性壁材８の上部を囲む補強部材を設けたり、圧縮性壁材８と側板９b1、９b2の間にスペーサを配置することもできる。
【００１５】
なお、これら上部ランナー２、下部ランナー３、スライドスペーサ９の材質は、一般構造用圧延鋼材、溶融亜鉛メッキ鋼板、一般構造用軽量鋼等が選択されるが、所定の強度を有せば強化合成樹脂等を用いることができる。
【００１６】
施工に当たっては、上部ランナー２の両側板２ｂ、２ｂ間に非圧縮性壁材７と圧縮性壁材８とを重ね合わせ、この上端をはめ込む。一方、下端は、下部ランナー３の側板３ｂに押し付けるように位置決めし、補助金具１４を用いて非圧縮性壁材７の下端を固定する。この際、非圧縮壁材７の上端と、上部ランナー２の天板２ａの間には、隙間が生じ、一方、スライドスペーサ９の天板９ａ及び側板９b2と、上部ランナー２の天板２ａ及び側板２ｂとはそれぞれ当接するように、非圧縮壁材７の高さ、及びスライドスペーサ９の固定位置が設定される。
【００１７】
これら非圧縮性壁材７及び圧縮性壁材８を建物の構造体に建て込んでいくにあたり、隣合う壁材同士では、表裏が逆になるように、すなわち、図３に示すように、非圧縮性壁材７と圧縮性壁材８とが互い違いになるように、配置される。なお、その後、両側に耐火被覆および化粧板を兼ねるボード１１、ボード１２を金具等で固定する。
【００１８】
上記のように構築した複合間仕切壁１では、上階床スラブ下面側の上部ランナー２と複合間仕切壁１とは、非圧縮性壁材７の側面及びスライドスペーサ９を介して接触する。そのため、建物に振動が加わり構造体が歪み、複合間仕切壁１の上端と構造体との接触部に力がかかっても、スライドスペーサ９がスライドして、この部分が破壊されることを防止する。特に、本実施例では、スライドスペーサ９の天板９ａが上部ランナー２の天板２ａと接触しているために、垂直方向に移動する自由度を制限する一方、水平方向には自由にスライドするため、地震や交通振動によっても取り付け部が破損しにくい複合間仕切壁１を構築することができる。
【００１９】
また、スライドスペーサ９を用いて、圧縮性壁材８を非圧縮性壁材７に固定することができるために、これらを上部ランナー２に差し込む際は、非圧縮性壁材７と圧縮性壁材８を合わせた状態で、簡単に建物の構造体に立て込むことができ、施工効率を向上させることができる。
【００２０】
なお、建物の振動により、スライドスペーサ９が上部ランナー２との間で擦れて摩擦音を発生させる可能性がある。このため、フッ素樹脂テープをスライドスペーサ２に貼着し、または、テフロン板など挟むなどして、摩擦係数の小さい滑り部材を上部ランナー２とスライドスペーサ９との間に介在させれば、摩擦音の発生を防止することができる。
【００２１】
また、上記実施例においては、それぞれの非圧縮性壁材７毎にスライドスペーサ９を２つ用いて非圧縮性壁材７を固定したが、この数は非圧縮性壁材７の横幅等に応じて任意に選択できる。さらに、スライドスペーサ９を上部ランナー２のように横長に形成することにより、１つでまかなうことも可能である。
【００２２】
【発明の効果】
以上説明したように、本発明の複合間仕切壁の上部取付構造によっては、スライドスペーサにより、複合間仕切壁が建物の構造体下面に設けたランナーに対してスライドするために、地震や交通振動によって構造体が歪んでも、複合間仕切壁の上部にかかる力を逃がすことができ、同部分の破損を防止することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an upper mounting structure for a composite partition wall.
[0002]
[Prior art]
As a conventional upper mounting structure of a composite partition plate, for example, a technique described in Japanese Utility Model Publication No. 55-16008 is known.
[0003]
This conventional method will be briefly described with reference to FIG. FIG. 4A is a side sectional view of a composite partition wall constructed by the same method, and FIG. 4B is a plan sectional view of the composite partition wall.
[0004]
That is, in the conventional composite partition wall, the runners 2 and 2 are arranged so as to face each of the ceiling 4 and the floor 5 which are the structures of the building, and the runners 2 and 2 are fixed with the fasteners 6 such as nails. Then, a hollow panel 7 having a mouth-shaped cross section, which is formed by bending a gypsum board along a V groove formed on the surface thereof, is built between the runners 2 and 2 with a spacer 13 interposed. The spacer 13 arranged at the position of the upper hollow panel 7 is tightly fixed to the runner 2 in order to maintain the arrangement position.
[0005]
At this time, the plurality of hollow panels 7 are alternately shifted in one direction in the thickness direction of the wall and are arranged in a staggered manner, during which the sheet-like fibrous material 8 is meandered between the hollow panels 7. And place them. Boards 11 and 12 are doubly attached to both sides of the hollow panel 7 and the fibrous material 8 arranged as described above.
[0006]
[Problems to be solved by the invention]
However, in the above-mentioned prior art, the upper portions of the fibrous material 8 and the hollow panel 7 are tight and difficult to move due to the spacers 13, and accordingly, the degree of freedom of the hollow panel 7 and the fibrous material 8 moving in the plane direction of the wall is increased. Therefore, if the structure of the building is deformed during an earthquake or due to traffic vibration, the force concentrates on the upper structure of the composite partition wall due to its inertia, etc., and this part may be destroyed. Was.
[0007]
Therefore, the present invention proposes a structure in which even if the structure of the building is deformed due to an earthquake or traffic vibration, the two partition walls and the runner are allowed to move between the two, and the upper mounting structure is hardly damaged. Aim.
[0008]
[Means for Solving the Problems]
The present invention combines an incompressible wall material selected from ALC board, extruded board and PC board with a compressible wall material selected from glass wool, rock wool and ceramic fiber blanket, and performs non-compression. In the structure in which the upper part of the composite partition wall in which the compressible wall material and the compressible wall material are arranged alternately is attached to the lower surface of the structure of the building, the upper part of the composite partition wall is attached to the lower surface of the structure of the building, A runner having a U-shaped cross section, having a top plate having a width of the thickness and both side plates, and containing the upper portion of the compressible wall material inside, and being fixed to the upper portion of the incompressible wall material, A top plate having a width obtained by subtracting the thickness of the incompressible wall material from the width of the top plate of the runner and a slide spacer having a U-shaped cross section having both side plates, and an upper portion of the incompressible wall material And the slide spacer Inside the runner, to constitute an upper mounting structure of a composite partition wall, characterized in that it is slidably supported solves the above problems.
[0009]
Further, a structure may be adopted in which a sliding member having a small coefficient of friction is interposed between the inner surface of the side plate of the runner and the outer surface of the side plate of the slide spacer.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to FIGS. The present embodiment describes a structure in which a composite partition wall composed of an incompressible wall material and a compressible wall material is disposed between the lower surface (ceiling) of the upper floor slab and the lower floor slab. FIG. 1 is a partial cross-sectional perspective view in which a composite partition wall is attached between an upper floor slab and a lower floor slab of a building, and FIG. 2 is an upper side sectional view showing a mounting structure of the composite partition wall. FIG. 3 is a plan sectional view of the composite partition wall taken along line AA in FIG.
[0011]
As shown in FIG. 1, the composite partition wall 1 is arranged such that the compressible wall material 8 and the incompressible wall material 7 are overlapped and the incompressible wall material 7 and the compressible wall material 8 are alternately arranged. Formed. The compressible wall material 8 is made of glass wool, rock wool, ceramic fiber blanket, or the like as its material. Further, as the non-compressible wall material 7, an ALC plate, an extruded plate, a PC plate or the like is used.
[0012]
An upper runner 2, which is a long metal rail, is fixed to a lower surface 4 of an upper floor slab, which is a structure of the building, using a fastener 6 such as a nail. As shown in FIGS. 1 and 2, the upper runner 2 is composed of a top plate 2a having a predetermined width, and side plates 2b and 2b with both side edges rising in the width direction, and has a U-shaped cross section. . The inner surface of the top plate 2a on which the side plates 2b and 2b stand up on both sides has a width obtained by combining the thickness of the incompressible wall material 7 and the width of a slide spacer 9 described later.
[0013]
On the upper surface of the lower floor slab 5, the lower runner 3, which is also a long metal rail, is fixed using nails (not shown). As shown in FIG. 1, the lower runner 3 is composed of a plate 3a and a side plate 3b with one side edge rising.
[0014]
A slide spacer 9 that holds a space for mounting the compressible wall member 8 is fixed to an upper side surface of the incompressible wall member 7. The slide spacer 9 is a metal fitting having a top plate 9a and side plates 9b1 and 9b2 with both side edges rising, and having a U-shaped cross section. One side plate 9b1 is longer than the other side plate 9b2, and the same side plate 9b1 is fastened to the side surface of the incompressible wall member 7 using a fastener 10 such as a nail, a screw, a bolt, or a staple. The width between both side plates 9b1 and 9b2 of the slide spacer 9 is substantially the same as the width of the compressible wall material 8, or has a width slightly smaller. Note that the width between the side plates 9b1 and 9b2 is made larger than the width of the compressible wall material 8, and a reinforcing member surrounding the upper part of the compressible wall material 8 is provided, or between the compressible wall material 8 and the side plates 9b1 and 9b2. Spacers can also be arranged.
[0015]
The material of the upper runner 2, the lower runner 3, and the slide spacer 9 is selected from rolled steel for general structures, hot-dip galvanized steel sheet, lightweight steel for general structures, and the like. Resin or the like can be used.
[0016]
In the construction, the incompressible wall material 7 and the compressible wall material 8 are overlapped between the side plates 2b, 2b of the upper runner 2, and the upper ends thereof are fitted. On the other hand, the lower end is positioned so as to be pressed against the side plate 3 b of the lower runner 3, and the lower end of the incompressible wall material 7 is fixed using the auxiliary fitting 14. At this time, a gap is formed between the upper end of the non-compressed wall member 7 and the top plate 2a of the upper runner 2, while the top plate 9a and the side plate 9b2 of the slide spacer 9 and the top plate 2a of the upper runner 2 and The height of the non-compressed wall member 7 and the fixed position of the slide spacer 9 are set so as to abut against the side plate 2b.
[0017]
When the non-compressible wall material 7 and the compressible wall material 8 are built into the structure of the building, the adjacent wall materials are turned upside down, that is, as shown in FIG. The compressible wall material 7 and the compressible wall material 8 are arranged so as to be alternated. After that, the board 11 and the board 12 which also serve as a fireproof coating and a decorative board are fixed on both sides with metal fittings.
[0018]
In the composite partition wall 1 constructed as described above, the upper runner 2 on the lower surface side of the upper floor slab and the composite partition wall 1 are in contact with each other via the side surface of the incompressible wall material 7 and the slide spacer 9. For this reason, even if vibration is applied to the building and the structure is distorted, and even if a force is applied to the contact portion between the upper end of the composite partition wall 1 and the structure, the slide spacer 9 is prevented from sliding and breaking this portion. . In particular, in the present embodiment, since the top plate 9a of the slide spacer 9 is in contact with the top plate 2a of the upper runner 2, the degree of freedom of movement in the vertical direction is restricted, while the slide is free in the horizontal direction. Therefore, it is possible to construct the composite partition wall 1 in which the mounting portion is hardly damaged even by an earthquake or traffic vibration.
[0019]
Further, since the compressible wall material 8 can be fixed to the incompressible wall material 7 using the slide spacer 9, when these are inserted into the upper runner 2, the incompressible wall material 7 and the In a state where the materials 8 are put together, they can be easily erected in the structure of the building, and the construction efficiency can be improved.
[0020]
In addition, the vibration of the building may cause the slide spacer 9 to rub against the upper runner 2 to generate a frictional sound. For this reason, if a sliding member having a small friction coefficient is interposed between the upper runner 2 and the slide spacer 9 by sticking a fluororesin tape to the slide spacer 2 or sandwiching a Teflon plate or the like, the friction noise can be reduced. Occurrence can be prevented.
[0021]
In the above embodiment, two slide spacers 9 are used to fix the incompressible wall material 7 for each incompressible wall material 7. However, this number depends on the width of the incompressible wall material 7 and the like. It can be arbitrarily selected according to. Further, by forming the slide spacer 9 horizontally long like the upper runner 2, it is also possible to cover one.
[0022]
【The invention's effect】
As described above, depending on the upper mounting structure of the composite partition wall of the present invention, the slide partition causes the composite partition wall to slide with respect to the runner provided on the lower surface of the structure of the building. Even if the body is distorted, the force applied to the upper part of the composite partition wall can be released, and the same part can be prevented from being damaged.
