【０００２】
【従来の技術】
建築物の中でも、住宅、店舗、ホテル等は意匠性を高めるため、無垢木材、化粧合板等を用いて、腰壁を形成することが多く行われる。また、建材生産の工業化に伴い、これら材料を用いた矩形状の腰壁パネルを連続して取付けることにより腰壁を設ける構造が各種提案されている。

【発明が解決しようとする課題】
しかしながら、これら従来のパネル方式の腰壁は、確かに材質的には、木目調など高い装飾性を有するものの、同じ外観でかつ表面が平面形状の腰壁パネルが多数連続して並ぶため、腰壁パネル間の目透かし目地が一定間隔で繰り返されるだけで、立体性を欠く単調な外観となり、重厚感に乏しく、また意匠性が低いものであった。
【０００５】
また、近年高齢者、障害者への配慮のため壁に手摺を設ける必要性が増加している。そしてこれら手摺は機能上、床面から７５０ｍｍの高さを標準とし、これは通常、腰壁の範囲に入る。しかし、例えば装飾等のため固有の表面形状を具えた腰壁上には手摺の取り付けが困難であり、また取付けるにしても専用のブラケットを必要とした。
【０００６】
本発明は、以上のような問題点に鑑み案出なされたもので、奥行きを感じさせ、重厚感が備わった高い意匠性が得ることができ、また標準のブラケットを用い、手摺を安定して取付けることができる腰壁構造の提供を目的としている。
【０００７】
【課題を解決するための手段】
本発明のうち請求項１記載の発明は、左右に連続する複数かつ矩形状の化粧板を具える腰壁構造であって、前記化粧板が、表面が垂直平面からなる第１の化粧板と、少なくとも両側部の表面が、厚さが両側端に向かって漸減することにより水平断面において円弧状の湾曲面からなる第２の化粧板とからなることを特徴としている。
【０００８】
また請求項２の発明は、前記第２の化粧板が、前記湾曲面の間が垂直平面からなることを特徴とし、請求項３記載の発明は、前記第１の化粧板と、第２の化粧板が交互に配されて左右に連続することを特徴としている。
【０００９】
また請求項４記載の発明は、側端部に、前記第１の化粧板を配置することを特徴とし、請求項５記載の発明は、前記第１、第２の化粧板の垂直平面に、手摺を支持するブラケットを取付けることを特徴としている。
【００１０】
【発明の実施の形態】
以下本発明の実施の一形態を図面に基づき説明する。図１〜図５において、本発明の腰壁構造１は、壁本体２１の表面でかつ腰高さよりも低位に、複数かつ矩形状の化粧板２を左右に連続して形成される。
【００１１】
前記壁本体２１は、本例では、縦枠２２ａ、横枠２２ｂ、中桟２２ｃを矩形枠状に枠組みした壁パネル枠２２の両面に、石膏ボード、合板、ＭＤＦ（中質繊維板）等の壁下地材２３を接着、釘止め等で取付けた壁パネル２４を、柱、梁等建物構造体（図示せず）に固定して形成したものであり、壁パネル２４の工場生産により、品質安定と工期を短縮している。本例では、互いに直行する一方の壁パネル２４ａの端側面に、他方の壁パネル２４ｂの端面を当接取付することにより出隅部２５を形成しており、その表面に断面Ｌ字状のコーナー部材２６が取付けられる。
【００１２】
前記化粧板２は、図３に示すように、無垢木材、木材を薄く加工した突板で被覆した化粧合板、化粧樹脂シート貼り合板、リサイクル再生木材等を用い、左右側部の一方にあいじゃくり状の雄実２６ａ、他方に雌実２６ｂを具え、前記雄実２６ａの端面は化粧板２の表面側が裏面側より突出する傾斜面に形成され、前記雌実２６ｂの端面は雄実２６ａの先端形状に一致するように、端面が化粧板２の裏側面が突出する傾斜面に形成されている。
【００１３】
前記化粧板２は、図４に示すように、幅木２９の上に載置するとともに、上端を壁本体２１に腰高に取付けられた水平な見切縁２７の段部２８と壁本体２１間に嵌合された状態で、図３に示すように、その雄実２６ａを釘、ビス等の固着具３０で壁本体２１に固定する。次いで隣接する化粧板２の雌実２６ｂと前記雄実２６ａを重ね合わせ、かつ雄実２６ａの傾斜面に雌実２６ｂの傾斜面を押し付けて前記隣接する化粧板２の一端を固定した状態で他端の雄実２６ａを前記と同様に、固着具３０で壁本体２１に固定する。以下この繰り返しにより化粧板２を、雌実２６ｂ側に固着具を用いず、しかも隣接する化粧板２との間に緩みのない連続した取付を可能としている。
【００１４】
尚、本例では、雌実２６ｂより長く形成した雄実２６ａの基部が一部表面に露出することにより目透かし目地３１を形成し、外観にアクセントを加え、意匠性を高めている。
【００１５】
前記化粧板２は、第１の化粧板２Ａと第２の化粧板２Ｂとからなり、第１の化粧板２Ａは、表面が垂直平面３からなり、高さ５００〜１２００ｍｍ、幅１００〜５００ｍｍ、厚み３〜２０ｍｍの矩形平板で形成され、本例では、高さ７４０ｍｍ、幅２２５ｍｍ、厚み５．５ｍｍであり、また両側に前記雄実２６ａと、雌実２６ｂを具える。
【００１６】
前記第２の化粧板２Ｂは、その表面中央に縦長に形成される垂直平面３の両側部に、厚さが両側端に向かって漸減することにより水平断面において円弧状の湾曲面４を具え、厚みは中央の垂直平面３で５〜５０ｍｍ、湾曲面４で３〜３０ｍｍ、高さ５００〜１２００ｍｍ、幅５０〜３００ｍｍの矩形板で形成され、本例では、厚みは垂直平面３で７ｍｍ、湾曲面４では７ｍｍから両側端に向かって４．５ｍｍに漸減し、高さ７４０ｍｍ、幅１１７ｍｍであり、また湾曲面４表面は、曲率半径１５０ｍｍに曲成される。
【００１７】
また前記湾曲面４は、無垢木材に対しルーター加工等加工機を用いた切削加工、湾曲面４を形成した修正材、ＭＤＦ等の芯材表面への化粧シート貼り加工、リサイクル再生木材の押出し成形等の生産方法により形成する。
【００１８】
このように、本例では、前記第２の化粧板２Ｂが配置されることで、腰壁表面に湾曲面４による凹凸が形成され、かつその表面に立体感と投光を受けて陰影が表れ、深みと厚みを感じさせる重厚感が備わり、高い意匠性が得られる。
【００１９】
更に本例では、第１の化粧板２Ａと第２の化粧板２Ｂを交互に配置して左右に連続している。これにより、第２の化粧板２Ｂにより形成される湾曲状の凹凸が、第１の化粧板２Ａの垂直平面により隔てられて一定間隔で形成されるため、繰り返しのリズムを感じさせ、より高い重厚感が備わり、一層高い意匠性が得られる。
【００２０】
また、図１に示すように、腰壁構造１の側端部に、第１の化粧板２Ａを配置する。化粧板２の取付作業において、腰壁全体の幅の違いは、側端部の化粧板２を切断して調整を行うが、第２の化粧板２Ｂを切断すると、湾曲面４の途中で途切れると外観に違和感が生じて見栄えを悪くする。しかし第１の化粧板２Ａは、どの箇所で切断してもその厚さは一定であり、見栄えを損なうことなく前記調整を容易になしえる。
【００２１】
さらに、腰壁を設ける壁自体の長さ、出入口の位置等の条件により、腰壁の長さは個々に異なる。そこで、図１に示すように、予め計算で得られる腰壁構造１全体の幅調整寸法を等分し、左右の側端部に配置される第１の化粧板２Ａを同幅に切断して配置すると、両側端部の外観のバランスが維持されるため、見栄えが一層良好となる。
【００２２】
また、近年高齢者、障害者への配慮のため壁に手摺５を設ける必要性が増加しており、腰壁構造１においては、図５に示すように、第２の化粧板２Ｂの垂直平面３に、端部ブラケット６ａと中間部ブラケット６ｂを１．５〜２．５ｍの間隔で同じ高さで取付け、水平棒状の手摺５の端部、中間部を支持している。これにより、複雑な取付面の形状に対応した特殊なブラケットを必要とせず、フラットな取付基板３２を具えた普通のブラケット６を用いることができるため、取付作業を標準化でき、また垂直平面に取付けたブラケット６で支持される手摺５の取付強度が安定している。
【００２３】
また、本例では、図２に示すように、出隅部２５を介して直行する双方の壁本体２１ａ、２１ｂに同構成の腰壁構造１を形成しており、コーナー部材２６に隣接する双方の前記第１の化粧板２Ａは、共に同幅に形成して外観を揃えることが好ましい。
【００２４】
図６、図７は、側端部に配置した第１の化粧板２Ａの間に、垂直平面３の両側部に円弧状の湾曲面４を具えた第２の化粧板２Ｂを連続して配置する形態を例示し、湾曲状の凹凸が短い周期で連続的に形成されるため、躍動感に富み、変化を感じさせる高い意匠性が得られる。
【００２５】
また手摺５のブラケット６は、第２の化粧板２Ｂの垂直平面３に取付けられ、第２の化粧板２Ｂが連続するため、ブラケット６の取付ピッチは必要強度に応じてきめ細かく設定でき、これにより手摺が充分な強度で取付される。
【００２６】
図８、図９は、第１の化粧板２Ａと、両側部を含んだ前面全体において、厚さが両側端に向かって漸減する湾曲面４からなる第２の化粧板２Ｂを、交互に配置した形態を例示するものである。本例では、第２の化粧板２Ｂの全面に亘る湾曲面４で形成するの凹凸形状が、立体感の印象を強めると共に表面の陰影が強調され、重厚感を増して、高い意匠性が得られる。本例では、手摺５のブラケット６は、第１の化粧板に取付ける。
【００２７】
【発明の効果】
上述したように、請求項１記載の発明では、左右に連続する複数かつ矩形状の化粧板を具えることを基本とし、化粧板が、表面が垂直平面からなる第１の化粧板と、少なくとも両側部の表面が、厚さが両側端に向かって漸減することにより水平断面において円弧状の湾曲面からなる第２の化粧板とからなるので、第２の化粧板により、表面に湾曲状の凹凸が形成されるため、厚みを感じさせる重厚感が備わり、高い意匠性が得られ、表面が垂直平面のからなる第１の化粧板上に、標準のブラケットを用いて手摺を安定して取付できる。
【００２８】
また前記第２の化粧板の湾曲面の間を垂直平面とすることにより、第２の化粧板上においても、標準のブラケットにより手摺を安定して取付でき、第１の化粧板と、第２の化粧板を交互に配して左右に連続することにより、第２の化粧板による湾曲状の凹凸が、一定間隔で形成されて、繰り返しのリズムを感じる重厚感と、高い意匠性が得られる。
【００２９】
また腰壁構造の側端部に第１の化粧板を配置することにより、見栄えを損なうことなく腰壁の幅の違いの調整を行え、第１、第２の化粧板の垂直平面に、手摺を支持するブラケットを取付けることにより普通のブラケットを用いた標準的な作業により、手摺を安定して取付できる。

[0004]
[Problems to be solved by the invention]
However, although these conventional panel-type waist walls certainly have a high decorative property such as woodgrain, the waist wall panels having the same appearance and a flat surface are lined up continuously, so When the openwork joints between the wall panels were repeated at regular intervals, the appearance became monotonous lacking the three-dimensionality, the solid feeling was poor, and the design was low.
[0005]
In addition, in recent years, there is an increasing need to provide handrails on walls for consideration of the elderly and the disabled. These handrails are functionally standardized at a height of 750 mm from the floor, which usually falls within the range of the waist wall. However, it is difficult to attach a handrail on a waist wall having a unique surface shape for decoration or the like, and even if it is attached, a special bracket is required.
[0006]
The present invention has been devised in view of the above-described problems, and makes it possible to feel depth, obtain a high design with a solid feeling, and stably use a standard bracket to stabilize a handrail. The purpose is to provide a waist wall structure that can be mounted.
[0007]

At least the surfaces of both side portions are characterized in that the thickness is gradually reduced toward both side ends, and the second decorative plate has an arc-shaped curved surface in a horizontal cross section.
[0008]
The invention according to claim 2 is characterized in that the second decorative plate is formed by a vertical plane between the curved surfaces, and the invention according to claim 3 is configured such that the first decorative plate and the second decorative plate The decorative plates are arranged alternately and are continuous left and right.
[0009]
The invention according to claim 4 is characterized in that the first decorative board is arranged at a side end, and the invention according to claim 5 is arranged on a vertical plane of the first and second decorative boards, A bracket for supporting a handrail is attached.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to the drawings. 1 to 5, the waist wall structure 1 of the present invention is formed with a plurality of rectangular decorative boards 2 on the surface of the wall main body 21 and lower than the waist height, continuously on the left and right.
[0011]
In this example, the wall main body 21 is formed of a plaster board, a plywood, an MDF (medium fiber board), and the like on both sides of a wall panel frame 22 in which a vertical frame 22a, a horizontal frame 22b, and a middle crosspiece 22c are framed in a rectangular frame shape. The wall panel 24 to which the wall base material 23 is attached by nailing or the like is formed by fixing it to a building structure (not shown) such as a pillar or a beam. And shortening the construction period. In this example, an end corner portion 25 is formed by abuttingly attaching an end surface of the other wall panel 24b to an end side surface of one wall panel 24a that is perpendicular to the other, and a corner having an L-shaped cross section is formed on the surface. The member 26 is attached.
[0012]
As shown in FIG. 3, the decorative board 2 is made of solid wood, decorative plywood covered with a veneer made of thin wood, decorative resin sheet-attached plywood, recycled wood, and the like. A male boss 26a and a female boss 26b on the other end, the end surface of the male boss 26a is formed as an inclined surface on the front side of the decorative plate 2 protruding from the back surface, and the end surface of the female boss 26b is a tip of the male boss 26a. The end surface is formed on an inclined surface from which the back surface of the decorative board 2 projects so as to match the shape.
[0013]
As shown in FIG. 4, the decorative board 2 is placed on a skirting board 29, and an upper end is provided between a step 28 of a horizontal parting edge 27 attached to the wall main body 21 at a waist height and the wall main body 21. In the fitted state, as shown in FIG. 3, the male member 26a is fixed to the wall main body 21 with a fixing tool 30 such as a nail or a screw. Next, the female face 26b of the adjacent decorative board 2 is superimposed on the male face 26a, and the inclined face of the female face 26b is pressed against the inclined face of the male face 26a to fix one end of the adjacent decorative board 2 to the other. The male end 26a at the end is fixed to the wall main body 21 with the fastener 30 in the same manner as described above. By repeating this process, the decorative board 2 can be continuously attached to the decorative board 2 without loosening without using a fixing tool on the female female 26b side.
[0014]
In this example, the base of the male seed 26a formed longer than the female seed 26b is partially exposed on the surface to form the watermark joint 31 to add an accent to the appearance and enhance the design.
[0015]
The decorative panel 2 includes a first decorative panel 2A and a second decorative panel 2B, and the first decorative panel 2A has a surface formed of a vertical plane 3, a height of 500 to 1200 mm, a width of 100 to 500 mm, It is formed of a rectangular flat plate having a thickness of 3 to 20 mm. In the present example, the height is 740 mm, the width is 225 mm, and the thickness is 5.5 mm, and the male nut 26a and the female nut 26b are provided on both sides.
[0016]
The second decorative plate 2B has arcuate curved surfaces 4 in a horizontal cross section by gradually decreasing the thickness toward both side edges on both sides of a vertical plane 3 formed vertically in the center of the surface, The thickness is 5 to 50 mm in the central vertical plane 3, 3 to 30 mm in the curved surface 4, 500 to 1200 mm in height, and 50 to 300 mm in width. In this example, the thickness is 7 mm in the vertical plane 3 and curved. The surface 4 gradually decreases from 7 mm to 4.5 mm toward both ends, has a height of 740 mm and a width of 117 mm, and has a curved surface 4 having a radius of curvature of 150 mm.
[0017]
In addition, the curved surface 4 is formed by cutting a solid wood with a processing machine such as a router, modifying a material having the curved surface 4, attaching a decorative sheet to a core material such as MDF, and extruding recycled wood. And the like.
[0018]
As described above, in the present example, the unevenness due to the curved surface 4 is formed on the waist wall surface by arranging the second decorative plate 2B, and a shadow appears due to the three-dimensional effect and light projection on the surface. It has a profound feeling of depth and thickness, and high designability is obtained.
[0019]
Further, in the present example, the first decorative boards 2A and the second decorative boards 2B are arranged alternately and are continuous left and right. As a result, the curved irregularities formed by the second decorative board 2B are formed at regular intervals separated by the vertical plane of the first decorative board 2A, so that a repetitive rhythm is felt and a higher weight is obtained. A feeling is provided, and higher designability is obtained.
[0020]
In addition, as shown in FIG. 1, a first decorative board 2 </ b> A is arranged at a side end of the waist wall structure 1. In the mounting work of the decorative panel 2, the difference in the width of the entire waist wall is adjusted by cutting the decorative panel 2 at the side end, but when the second decorative panel 2B is cut, the width is interrupted in the middle of the curved surface 4. And the appearance is uncomfortable, and the appearance is deteriorated. However, the thickness of the first decorative board 2A is constant no matter where it is cut, and the adjustment can be easily performed without impairing the appearance.
[0021]
Furthermore, the length of the waist wall differs individually depending on conditions such as the length of the wall itself on which the waist wall is provided and the position of the entrance. Therefore, as shown in FIG. 1, the width adjustment dimensions of the entire lumbar wall structure 1 obtained in advance by calculation are equally divided, and the first decorative boards 2A arranged on the left and right side edges are cut into the same width. By arranging, the balance of the appearance of both side ends is maintained, so that the appearance is further improved.
[0022]
In addition, in recent years, the necessity of providing a handrail 5 on a wall for consideration of the elderly and the disabled has been increasing. In the waist wall structure 1, as shown in FIG. 3, an end bracket 6a and an intermediate bracket 6b are attached at the same height at an interval of 1.5 to 2.5 m to support an end and an intermediate portion of the horizontal bar-shaped handrail 5. This eliminates the need for a special bracket corresponding to the shape of the complicated mounting surface, and allows the use of the ordinary bracket 6 having the flat mounting substrate 32, so that the mounting operation can be standardized and the mounting can be performed on a vertical plane. The mounting strength of the handrail 5 supported by the bracket 6 is stable.
[0023]
Further, in this example, as shown in FIG. 2, the waist wall structure 1 having the same configuration is formed on both wall bodies 21 a and 21 b which are perpendicular to each other via the protruding corner portion 25, and the both sides adjacent to the corner member 26 are formed. It is preferable that both of the first decorative boards 2A are formed to have the same width to make the appearance uniform.
[0024]
FIGS. 6 and 7 show that a second decorative plate 2B having an arcuate curved surface 4 on both sides of a vertical plane 3 is continuously disposed between first decorative plates 2A disposed at side ends. In the illustrated example, the curved irregularities are continuously formed in a short cycle, so that a high design that is rich in a sense of dynamism and has a sense of change can be obtained.
[0025]
In addition, the bracket 6 of the handrail 5 is attached to the vertical plane 3 of the second decorative panel 2B, and the second decorative panel 2B is continuous. Therefore, the mounting pitch of the bracket 6 can be set finely according to the required strength. The handrail is attached with sufficient strength.
[0026]
FIGS. 8 and 9 show alternately arranged first decorative panels 2A and second decorative panels 2B each having a curved surface 4 whose thickness gradually decreases toward both side edges on the entire front surface including both side portions. This is an example. In this example, the uneven shape formed by the curved surface 4 over the entire surface of the second decorative board 2B enhances the three-dimensional impression, enhances the shadow of the surface, increases the solid feeling, and achieves high designability. Can be In this example, the bracket 6 of the handrail 5 is attached to the first decorative board.
[0027]
【The invention's effect】
As described above, the invention according to claim 1 is basically provided with a plurality of rectangular decorative boards that are continuous left and right, and the decorative board includes at least a first decorative board whose surface is a vertical plane. Since the surfaces of both sides are composed of a second decorative plate having an arc-shaped curved surface in a horizontal cross-section by gradually decreasing the thickness toward the both ends, the surface is curved by the second decorative plate. Due to the unevenness, it has a solid feeling to feel the thickness, high designability is obtained, and the handrail is stably mounted on the first decorative board with a vertical flat surface using a standard bracket it can.
[0028]
In addition, by setting a vertical plane between the curved surfaces of the second decorative panel, the handrail can be stably mounted on the second decorative panel by a standard bracket, and the first decorative panel and the second decorative panel can be attached to the second decorative panel. By alternately arranging the decorative panels of the second decorative panel on the left and right, curved irregularities formed by the second decorative panel are formed at regular intervals, and a profound feeling of repetitive rhythm and high designability can be obtained. .
[0029]
Also, by disposing the first decorative panel at the side end of the waist wall structure, the difference in width of the lumbar wall can be adjusted without deteriorating the appearance, and the handrail is placed on the vertical plane of the first and second decorative panels. The handrail can be stably attached by the standard work using the ordinary bracket by attaching the bracket for supporting the handrail.
