Description

本発明は、建物の間仕切壁を構成する壁下地装置に関する。 The present invention relates to a wall base device that constitutes a partition wall of a building.

従来より、屋内空間を間仕切る間仕切壁は、横桟や間柱等の壁下地の壁厚方向両側に面材が固定されて構成されている。このような間仕切壁では、間仕切壁の下端部の壁厚方向両側に床仕上材が突き付けられる。そのため、床仕上材と間仕切壁との間に隙間が形成され易くなる。
例えば、下記特許文献1には、間仕切パネルの下フレームに固定された固定部材を床仕上材の間に配されたスペーサに固定した構成とされた間仕切壁構造が開示されている。また、この間仕切壁構造では、間仕切パネルの厚さ方向両側に張り出した固定部材の張出部を覆う巾木を取り付けた構成とされている。
Conventionally, a partition wall for partitioning an indoor space is configured by fixing face materials on both sides in the wall thickness direction of a wall base such as a cross rail or a stud. In such a partition wall, floor finishing materials are abutted on both sides of the lower end portion of the partition wall in the wall thickness direction. Therefore, a gap is likely to be formed between the floor finishing material and the partition wall.
For example, Patent Document 1 below discloses a partition wall structure in which a fixing member fixed to a lower frame of a partition panel is fixed to a spacer arranged between floor finishing materials. Further, in this partition wall structure, a width strip covering the overhanging portion of the fixing member overhanging on both sides in the thickness direction of the partition panel is attached.

The upper horizontal rail 30 to be fixed and the lower horizontal rail 10 to which the lower end portion 20b of the vertical rail 20 is fixed are provided.
The building to be constructed by the wall base device 1 is not limited to a house such as a detached house or an apartment house, but may be a building such as a commercial facility or a public facility. The wall base device 1 can be installed at various locations.

また、この壁下地装置1の天井側の固定対象としての天井下地4は、LGS(軽量形鋼)等の鋼製下地や、木造下地でもよく、例えば、ハンガー(吊木)に支持された野縁受に固定された野縁でもよく、さらには、天井スラブでもよい。図例では、天井下地4に固定された天井パネル5の下面側に壁下地装置1を設けた例を示している。つまり、壁下地装置1の天井側を、天井パネル5を介して天井下地4に固定した例を示している。なお、このような態様に代えて、壁下地装置1の天井側を、天井下地4に直接的に固定した態様としてもよい。
また、この壁下地装置1の床側の固定対象としての床下地2は、例えば、根太や床下地ボード等でもよく、さらには、床スラブでもよい。また、床下地2は、床スラブ等に設けられた支持脚に根太等を介して支持されて二重床構造を構成する床下地ボードでもよい。床側の固定対象を、このような二重床構造の床下地2とし、天井側の固定対象を、上記のような吊天井構造の天井下地4とすれば、間取り変更等に容易かつ柔軟に対応することができる。
Further, the ceiling base 4 as a fixing target on the ceiling side of the wall base device 1 may be a steel base such as LGS (lightweight shaped steel) or a wooden base, for example, a field supported by a hanger (hanging tree). It may be a field edge fixed to the edge support, or it may be a ceiling slab. In the illustrated example, an example in which the wall base device 1 is provided on the lower surface side of the ceiling panel 5 fixed to the ceiling base 4 is shown. That is, an example is shown in which the ceiling side of the wall base device 1 is fixed to the ceiling base 4 via the ceiling panel 5. Instead of such a mode, the ceiling side of the wall base device 1 may be directly fixed to the ceiling base 4.
Further, the floor base 2 as a fixing target on the floor side of the wall base device 1 may be, for example, a joist, a floor base board, or the like, or may be a floor slab. Further, the floor base 2 may be a floor base board that is supported by support legs provided on a floor slab or the like via joists or the like to form a double floor structure. If the fixing target on the floor side is the floor base 2 having such a double floor structure and the fixing target on the ceiling side is the ceiling base 4 having a suspended ceiling structure as described above, it is easy and flexible to change the floor plan or the like. Can be accommodated.

壁下地装置1の壁厚方向両側に設けられる面材41は、略矩形平板状とされている。これら壁厚方向両側の面材41と壁下地装置1とによって間仕切壁が形成される。図例では、壁幅方向両側が通路等の空間となるように間仕切壁を設けた例を示している。また、壁下地装置1の壁厚方向両側のそれぞれに、一枚の面材41を設けた例を示している。また、間仕切壁の壁幅方向両側に帯板状の化粧材48,48を設けた例を示している。なお、壁下地装置1によって形成される間仕切壁としては、上記したような態様に限られず、壁厚方向両側のそれぞれに複数枚の面材41が設けられる態様や、壁幅方向両側または一方側に他の壁が直交状に設けられる態様等でもよい。 The face members 41 provided on both sides of the wall base device 1 in the wall thickness direction have a substantially rectangular flat plate shape. A partition wall is formed by the face members 41 on both sides in the wall thickness direction and the wall base device 1. In the illustrated example, an example in which a partition wall is provided so that both sides in the wall width direction form a space such as a passage is shown. Further, an example in which one face material 41 is provided on each side of the wall base device 1 in the wall thickness direction is shown. Further, an example is shown in which strip-shaped decorative materials 48, 48 are provided on both sides of the partition wall in the wall width direction. The partition wall formed by the wall base device 1 is not limited to the above-described mode, but may be a mode in which a plurality of face members 41 are provided on both sides in the wall thickness direction, or both sides or one side in the wall width direction. Other walls may be provided orthogonally to each other.

また、面材41の上下寸法は、天井高に応じて適宜の寸法とされたものでもよく、例えば、2000mm〜3000mm程度でもよい。図例では、面材41の上下寸法を、縦桟20の上下寸法(長さ寸法)と略同寸法とした例を示している。また、この面材41の幅寸法(壁幅方向に沿う寸法)は、取扱性や施工性等の観点から適宜の寸法とされたものでもよく、例えば、300mm〜1500mm程度でもよい。
また、図例では、この面材41の裏面(壁下地装置1(縦桟20))側に、フレーム42を設けて壁パネル40とした例を示している。また、壁パネル40を、縦桟20の壁厚方向両側に固定した例を示している。フレーム42は、アルミ等の金属製とされ、面材41の裏面の四周端部に沿って枠状に設けられている。また、図例では、四周のフレーム42に加え、上下方向に延びるフレーム42とパネル幅方向に延びるフレーム42とを設けた例を示している。
Further, the vertical dimension of the face material 41 may be an appropriate dimension according to the ceiling height, and may be, for example, about 2000 mm to 3000 mm. In the illustrated example, an example is shown in which the vertical dimension of the face material 41 is substantially the same as the vertical dimension (length dimension) of the vertical rail 20. Further, the width dimension (dimension along the wall width direction) of the face material 41 may be an appropriate dimension from the viewpoint of handleability, workability, etc., and may be, for example, about 300 mm to 1500 mm.
Further, in the figure example, an example is shown in which a frame 42 is provided on the back surface (wall base device 1 (vertical rail 20)) side of the face material 41 to form a wall panel 40. Further, an example is shown in which the wall panel 40 is fixed to both sides of the vertical rail 20 in the wall thickness direction. The frame 42 is made of metal such as aluminum, and is provided in a frame shape along the four peripheral ends of the back surface of the face material 41. Further, in the figure example, in addition to the four-circle frame 42, an example in which a frame 42 extending in the vertical direction and a frame 42 extending in the panel width direction are provided is shown.

なお、面材41は、一般的な壁下地ボード、例えば、石膏ボード(プラスターボード)でもよく、インシュレーションボードやMDF(中密度繊維板)、ハードボード等の木質繊維板、木質積層板等の木質系ボードでもよい。また、面材41としては、このような石膏ボードや木質系ボードに限られず、例えば、0.5mm〜1.5mm程度の比較的に薄い鉄板等の金属板でもよい。また、面材41は、表面(室内側面)に化粧シートの貼着や塗装等の表面処理が施されて表面が化粧面とされたものでもよい。また、図例では、壁厚方向一方側の面材41に、配線器具としてコンセント(差込接続器)44とスイッチ(操作盤)45とを設けた例を示している。なお、壁下地装置1の壁厚方向両側に設けられる面材41(壁パネル40)としては、上記した例に限られず、その他、種々の構成とされたものの採用が可能である。 The face material 41 may be a general wall base board, for example, gypsum board (plaster board), or wood fiber board such as insulation board, MDF (medium density fiber board), hard board, or wood laminated board. It may be a system board. Further, the face material 41 is not limited to such a gypsum board or a wood-based board, and may be, for example, a metal plate such as a relatively thin iron plate having a thickness of about 0.5 mm to 1.5 mm. Further, the face material 41 may have a surface (indoor side surface) that has been subjected to surface treatment such as sticking or painting of a decorative sheet to make the surface a decorative surface. Further, in the illustrated example, an example is shown in which an outlet (plug-in connector) 44 and a switch (operation panel) 45 are provided as wiring devices on the face material 41 on one side in the wall thickness direction. The face materials 41 (wall panels 40) provided on both sides of the wall base device 1 in the wall thickness direction are not limited to the above examples, and other materials having various configurations can be adopted.

壁下地装置1の下横桟10は、図1(b)及び図3(b)に示すように、壁厚方向に沿う寸法(幅寸法)が縦桟20の壁厚方向に沿う寸法よりも大とされている。また、下横桟10は、壁厚方向両側に、縦桟20の下端部20bとによって面材41(本例では、壁パネル40)の下端部40aを受け入れる受入凹所14を構成する段壁面13を設けた構成とされている。このような構成とすれば、縦桟20の壁厚方向両側に固定される壁パネル40の下端部40aを受入凹所14に差し入れることができる。これにより、壁パネル40の下端部40aを見栄え良く納めることができ、また、壁パネル40の下端側の位置決めを容易に行うこともできる。また、下横桟10は、壁厚方向両側に、この下横桟10の壁厚方向両側に配される床仕上材3の端部上面3aを覆う突片部15を設けた構成としている。このような構成とすれば、間仕切壁の壁厚方向両側に配される床仕上材3の端部を見栄え良く納めることができる。これにより、巾木を設けない構造とすることもできる。 As shown in FIGS. 1 (b) and 3 (b), the lower horizontal rail 10 of the wall base device 1 has a dimension (width dimension) along the wall thickness direction larger than the dimension along the wall thickness direction of the vertical rail 20. It is said to be large. Further, the lower cross rail 10 is a stepped wall surface forming a receiving recess 14 for receiving the lower end portion 40a of the face material 41 (in this example, the wall panel 40) by the lower end portions 20b of the vertical rail 20 on both sides in the wall thickness direction. 13 is provided. With such a configuration, the lower end portions 40a of the wall panel 40 fixed on both sides of the vertical rail 20 in the wall thickness direction can be inserted into the receiving recess 14. As a result, the lower end portion 40a of the wall panel 40 can be stored in a good-looking manner, and the lower end side of the wall panel 40 can be easily positioned. Further, the lower cross rail 10 is configured to be provided with projecting piece portions 15 covering the upper surface 3a of the end portion of the floor finishing material 3 arranged on both sides of the lower cross rail 10 in the wall thickness direction on both sides in the wall thickness direction. With such a configuration, the ends of the floor finishing material 3 arranged on both sides of the partition wall in the wall thickness direction can be stored in a good-looking manner. As a result, it is possible to have a structure in which a timber is not provided.

この下横桟10は、図2に示すように、壁幅方向に長尺状とされている。この下横桟10の長さ寸法は、間仕切壁の壁幅寸法に応じて適宜の長さとしてもよく、取扱性や施工性等の観点から、例えば、500mm〜4000mm程度としてもよい。
また、この下横桟10は、上下方向に厚さ方向を沿わせて配される帯板状とされている。図例では、この下横桟10の下面(床下地2)側に、下方側に向けて開口し長手方向に延びる二本の凹溝を設けた例を示している。
この下横桟10の壁厚方向両側の段壁面13,13は、互いに向き合うように平行状に設けられている。また、これら段壁面13,13は、図3(a)に示すように、下横桟10の全長に亘って設けられている。これら段壁面13,13は、これらの間の下横桟10の上面から立ち上がるように設けられ、この上面に対して略垂直な面とされている。
これら段壁面13,13の立ち上がり寸法(段差寸法)は、縦桟20の壁厚方向両側に設けられる壁パネル40の下端側の壁厚方向外側への移動を抑制する観点等から適宜の寸法としてもよく、例えば、0.5mm〜5mm程度としてもよい。
As shown in FIG. 2, the lower cross rail 10 has an elongated shape in the wall width direction. The length dimension of the lower cross rail 10 may be an appropriate length according to the wall width dimension of the partition wall, and may be, for example, about 500 mm to 4000 mm from the viewpoint of handleability, workability, and the like.
Further, the lower cross rail 10 has a strip shape arranged along the thickness direction in the vertical direction. In the illustrated example, an example is shown in which two concave grooves that open downward and extend in the longitudinal direction are provided on the lower surface (floor base 2) side of the lower cross rail 10.
The stepped wall surfaces 13 and 13 on both sides of the lower cross rail 10 in the wall thickness direction are provided in parallel so as to face each other. Further, as shown in FIG. 3A, these step wall surfaces 13 and 13 are provided over the entire length of the lower cross rail 10. The step wall surfaces 13 and 13 are provided so as to rise from the upper surface of the lower cross rail 10 between them, and are formed to be substantially perpendicular to the upper surface.
The rising dimensions (step dimensions) of these stepped wall surfaces 13 and 13 are set as appropriate dimensions from the viewpoint of suppressing the movement of the lower end side of the wall panel 40 provided on both sides of the vertical rail 20 in the wall thickness direction to the outside in the wall thickness direction. It may be, for example, about 0.5 mm to 5 mm.

また、これら段壁面13,13間の壁厚方向に沿う寸法は、縦桟20の壁厚方向に沿う寸法に壁厚方向両側の壁パネル40,40の厚さ寸法を足し合わせた寸法(間仕切壁厚寸法)に応じた寸法とされている。図例では、これら段壁面13,13間の壁厚方向に沿う寸法を、間仕切壁厚寸法(壁厚方向一方側の面材41の表面から壁厚方向他方側の面材41の表面までの壁厚方向に沿う寸法)よりも僅かに大とした例を示している。
受入凹所14は、底側が段壁面13,13間の下横桟10の上面によって区画され、壁厚方向中央側が縦桟20の壁厚方向外側面によって区画され、壁厚方向外側が段壁面13によって区画されている。図例では、縦桟20の下端部20bの壁厚方向両側に形成される受入凹所14,14の壁厚方向に沿う寸法を互いに略同寸法とした例を示している。また、図例では、段壁面13,13間の下横桟10の上面が床仕上材3の上面と略同高さとなる構成とした例を示している。
Further, the dimension along the wall thickness direction between the stepped wall surfaces 13 and 13 is the dimension obtained by adding the thickness dimension of the wall panels 40 and 40 on both sides in the wall thickness direction to the dimension along the wall thickness direction of the vertical rail 20 (partition). The dimensions are set according to the wall thickness dimension). In the illustrated example, the dimension along the wall thickness direction between the stepped wall surfaces 13 and 13 is the partition wall thickness dimension (from the surface of the face material 41 on one side in the wall thickness direction to the surface of the face material 41 on the other side in the wall thickness direction). An example is shown in which the dimension is slightly larger than the dimension along the wall thickness direction).
The bottom side of the receiving recess 14 is partitioned by the upper surface of the lower cross rail 10 between the step wall surfaces 13 and 13, the center side in the wall thickness direction is partitioned by the wall thickness direction outer surface of the vertical rail 20, and the wall thickness direction outer side is the step wall surface. It is partitioned by 13. In the illustrated example, the dimensions of the receiving recesses 14 and 14 formed on both sides of the lower end portion 20b of the vertical rail 20 in the wall thickness direction are substantially the same as each other. Further, in the figure example, an example is shown in which the upper surface of the lower cross rail 10 between the step wall surfaces 13 and 13 is configured to have substantially the same height as the upper surface of the floor finishing material 3.

また、下横桟10の壁厚方向両側の突片部15,15は、下横桟10の壁厚方向両側の上端縁から壁厚方向外側に向けて突出するように設けられている。これら突片部15,15は、下横桟10の全長に亘って設けられている。また、これら突片部15,15は、それぞれの上面が段壁面13,13の上端に連なるように設けられている。
これら突片部15,15の下面から下横桟10の下面までの上下方向に沿う寸法は、図1(b)に示すように、床仕上材3の厚さ寸法に応じた寸法とされている。このような構成とすれば、下横桟10と床下地2との間にスペーサー等を設ける必要性を低減することができる。また、下横桟10の両側の突片部15,15を除いた部位を構成する横桟本体部11の壁厚方向外側面に床仕上材3の端面が突き合せられる。
Further, the projecting piece portions 15 and 15 on both sides of the lower cross rail 10 in the wall thickness direction are provided so as to project outward in the wall thickness direction from the upper end edges of both sides of the lower cross rail 10 in the wall thickness direction. These projecting piece portions 15 and 15 are provided over the entire length of the lower cross rail 10. Further, these projecting piece portions 15 and 15 are provided so that their upper surfaces are continuous with the upper ends of the step wall surfaces 13 and 13.
As shown in FIG. 1B, the dimensions along the vertical direction from the lower surfaces of the projecting pieces 15 and 15 to the lower surface of the lower cross rail 10 are set according to the thickness dimension of the floor finishing material 3. There is. With such a configuration, it is possible to reduce the need to provide a spacer or the like between the lower cross rail 10 and the floor base 2. Further, the end surface of the floor finishing material 3 is abutted against the outer surface of the horizontal rail main body 11 in the wall thickness direction, which constitutes a portion excluding the projecting pieces 15 and 15 on both sides of the lower horizontal rail 10.

また、これら突片部15,15の突出寸法(横桟本体部11の壁厚方向外側面から突出方向先端面までの壁厚方向に沿う寸法)は、床仕上材3の端部上面3aを覆い得るように、また、見栄え上の観点等から適宜の寸法としてもよい。これら突片部15,15の突出寸法を、例えば、0.5mm〜5mm程度としてもよい。また、これら突片部15,15の上下方向に沿う寸法(厚さ寸法)は、強度上の観点や見栄え上の観点等から適宜の寸法としてもよく、例えば、0.5mm〜5mm程度としてもよい。なお、図例では、これら突片部15,15の上面を、下面と平行な水平面状とした例を示しているが、壁厚方向外側に向かうに従い下るように傾斜する傾斜面状としてもよい。 Further, the projecting dimensions of the projecting pieces 15 and 15 (dimensions along the wall thickness direction from the outer surface of the cross rail main body 11 in the wall thickness direction to the tip surface in the projecting direction) are the upper surface 3a of the end portion of the floor finishing material 3. The dimensions may be appropriate so that they can be covered, and from the viewpoint of appearance and the like. The protruding dimensions of the projecting pieces 15 and 15 may be, for example, about 0.5 mm to 5 mm.

Further, since the upper cross rail 30 is movably supported by the cross rail support member 35 toward the ceiling base 4 side, the height of the upper end of each vertical rail 20 is different due to unevenness on the floor side or the like. In such a case, the upper end portion 20a can be fixed to the upper horizontal rail 30 without finely adjusting the length of the vertical rail 20. That is, it is possible to reduce the need to precisely fine-tune the height and levelness of the upper horizontal rail 30 and the length of the vertical rail 20 at the construction site, and it is possible to improve the workability. Further, since the upper end portion 20a of each vertical rail 20 can be fixed to the upper horizontal rail 30 supported by the horizontal rail support member 35 fixed to the ceiling base 4, the vertical rail 20 is installed in a frame-shaped state.
