本発明において「陶板」は、陶磁器からなるものであり、大便器または小便器下に床面に敷設されて使用される。図１は、小便器下に敷設される陶板の説明図である。図において、本発明による陶板１は、排水口２１のある床面２と、給水口３１のある壁面３との間に小便器４を設置するにあたり、床面２と小便器４の間に置かれる。なお、図にあるように、壁面３と小便器４との間にパネル５が設置されることがあるが任意である。図２は、陶板１の床面２への固定の態様を示す図であり、床面２にモルタル、接着剤等により固着される。図２が示すように、陶板１の便器と接する側の面は平坦であり、場合により化粧が施される、あるいは防汚のための加工、処理がなされていてよい。 In the present invention, the "pottery plate" is made of pottery and is used by laying it on the floor under a toilet bowl or a urinal. FIG. 1 is an explanatory diagram of a ceramic plate laid under a urinal. In the figure, the porcelain plate 1 according to the present invention is placed between the floor surface 2 and the urinal 4 when the urinal 4 is installed between the floor surface 2 having the drainage port 21 and the wall surface 3 having the water supply port 31. Toilet. As shown in the figure, the panel 5 may be installed between the wall surface 3 and the urinal 4, but it is optional. FIG. 2 is a diagram showing an aspect of fixing the ceramic plate 1 to the floor surface 2, and is fixed to the floor surface 2 with mortar, an adhesive, or the like. As shown in FIG. 2, the surface of the ceramic plate 1 on the side in contact with the toilet bowl is flat, and may be subjected to makeup, or may be processed or treated for antifouling.

他方、陶板１の床面２と接する側の面には、凹凸が設けられ、凹部にモルタル、接着剤などが入り込み、床面への固定をより確実にするよう機能する。図３は、陶板１の床面２と接する面の模式図であり、縦横に複数直交している部分が凸部１１、すなわち裏足であり、マス目に閉じた部分が凹部１２および１５である。図４は、図３に示される陶板１の一部拡大図であり、凸部１１、すなわち裏足が縦横に複数直交していており、その裏足に囲まれて形成されたマス目に閉じた凹部１２を備える。さらに、図３に示されるように、陶板１の中央には、排水管を通すための貫通孔１３と、この態様にあっては、この貫通孔１３と連続した孔としての、固定具を通すための貫通孔１４が設けられてなる。この図の態様にあっては、貫通孔１４は二か所に設けられてなる。 On the other hand, the surface of the porcelain plate 1 on the side in contact with the floor surface 2 is provided with irregularities, and mortar, an adhesive or the like enters the concave portions, and functions to ensure fixing to the floor surface. FIG. 3 is a schematic view of a surface of the ceramic plate 1 in contact with the floor surface 2, in which the portions orthogonal to each other in the vertical and horizontal directions are the convex portions 11, that is, the back legs, and the portions closed to the squares are the concave portions 12 and 15. be. FIG. 4 is a partially enlarged view of the ceramic plate 1 shown in FIG. 3, in which the convex portions 11, that is, the back legs are orthogonal to each other in a plurality of vertical and horizontal directions, and are closed to the squares formed by being surrounded by the back legs. It is provided with a recess 12. Further, as shown in FIG. 3, in the center of the ceramic plate 1, a through hole 13 for passing a drainage pipe and, in this embodiment, a fixing tool as a hole continuous with the through hole 13 are passed. A through hole 14 is provided for this purpose. In the aspect of this figure, the through holes 14 are provided at two places.

本発明にあっては、図３に示されるように、この裏足１１が、排水管用貫通孔１３の周辺部において、排水管用貫通孔１３の周辺部以外の領域よりも、その間隔が狭く配置されてなる。すなわち、図が示すように、排水管用貫通孔１３の周辺部における凹部１５は、排水管用貫通孔１２の周辺部以外の領域の凹部１２よりも小さいものとなる。 In the present invention, as shown in FIG. 3, the back legs 11 are arranged in the peripheral portion of the drainage pipe through hole 13 at a narrower interval than the region other than the peripheral portion of the drainage pipe through hole 13. Being done. That is, as shown in the figure, the recess 15 in the peripheral portion of the drainage pipe through hole 13 is smaller than the recess 12 in the region other than the peripheral portion of the drainage pipe through hole 12.

本発明の好ましい態様によれば、貫通孔１４は、本来、裏足１１が存在する箇所に設けられず、裏足が存在しない凹部１５の箇所に設けられる。図３は、貫通孔１４は、裏足１１が存在しない凹部１５の箇所に設けられた態様を示す According to a preferred embodiment of the present invention, the through hole 14 is not originally provided in the place where the back foot 11 is present, but is provided in the place where the back foot 15 is not present. FIG. 3 shows an embodiment in which the through hole 14 is provided in the recess 15 where the back foot 11 does not exist.

図５は、本発明による陶板を敷設しながら、小便器を設置する際の説明図である。図５に示されるように、陶板１を、床面２に設けられた排水口２１に、貫通孔１３を合わせて固定する。続いて、排水口２１と小便器の排水口（図示せず）とを、シール材６を介して、排水ソケット７により接続する。排水ソケット７は、小便器の排水口に接続する小便器側接続口７１と、リム部７２とを備え、リム部７２には、この排水ソケット７と陶板１とを床面２に固定するビスが通る、固定用ビス穴７３が設けられてなる。 FIG. 5 is an explanatory view when installing a urinal while laying a ceramic plate according to the present invention. As shown in FIG. 5, the ceramic plate 1 is fixed to the drainage port 21 provided on the floor surface 2 by aligning the through hole 13. Subsequently, the drainage port 21 and the drainage port (not shown) of the urinal are connected by the drainage socket 7 via the sealing material 6. The drainage socket 7 includes a urinal side connection port 71 connected to the drainage port of the urinal and a rim portion 72, and the rim portion 72 has a screw for fixing the drainage socket 7 and the ceramic plate 1 to the floor surface 2. A fixing screw hole 73 is provided through which the toilet can pass.

図６は、排水ソケット７の固定用ビス穴７３に、固定ビス８を貫通させて、床面２に打ち付け、陶板１と排水ソケット７を固定した状態を示す図である。本発明による陶板にあっては、上記のとおり、裏足１１が、排水管用貫通孔１３の周辺部において間隔が狭く配置されてなる。その結果、固定ビス８を打ち付けて、力が加わっても陶板１の変形は小さい。本発明によるこの効果は、間隔が狭く配置された複数の裏足１１が取り囲む凹部１５の位置に固定具用貫通孔１４が存在するよう構成されることで奏される。この効果は、凹部１５を取り囲む裏足１１の少なくとも一部が存在しない場合であっても期待でき、例えば図３に記載の態様にあっては、排水管用貫通孔１３と固定具用貫通孔１４は連続、連結して一体となっており、この連結部分の裏足１１が存在しない状態にあるが、少なくとも対向する一対の裏足１１が（図６の断面視方向に）存在するため、固定ビス８を打ち付け力が加わっても陶板１の変形は小さい。 FIG. 6 is a diagram showing a state in which the fixing screw 8 is passed through the fixing screw hole 73 of the drainage socket 7 and hit against the floor surface 2 to fix the ceramic plate 1 and the drainage socket 7. In the ceramic plate according to the present invention, as described above, the back legs 11 are arranged at a narrow space around the drainage pipe through hole 13. As a result, even if the fixing screw 8 is struck and a force is applied, the deformation of the ceramic plate 1 is small. This effect according to the present invention is achieved by configuring the fixing tool through hole 14 to exist at the position of the recess 15 surrounded by the plurality of back legs 11 arranged at a narrow interval. This effect can be expected even when at least a part of the back foot 11 surrounding the recess 15 is not present. For example, in the embodiment shown in FIG. 3, the drainage pipe through hole 13 and the fixture through hole 14 can be expected. Is continuously connected and integrated, and the back legs 11 of this connected portion do not exist, but at least a pair of opposite back legs 11 exist (in the cross-sectional view direction of FIG. 6), so that they are fixed. Even if the screw 8 is hit and the force is applied, the deformation of the ceramic plate 1 is small.

他方、図７は、本発明による陶板と異なり、裏足１１が、排水管用貫通孔１３の周辺部においても、排水管用貫通孔１３の周辺部以外の領域においても同様の広い間隔で設けられた、従来知られた陶板の模式図である。さらにこの態様にあっては、固定具を通すための貫通孔１４が、本来裏足が存在する位置にある。そのため、図６と同様に、固定ビス８を貫通させて、床面２に打ち付け、陶板１と排水ソケット７を固定すると、図８に示されるように、固定ビス８からの応力により陶板１がたわみ（図中の点線は、たわみを強調したものである）、場合よって割れにつながるおそれがある。図６に示されるように、本発明による陶板にあっては、固定ビス８からの応力は、裏足の間隔が狭いため、陶板１のたわみが小さく（図中の点線は、同様にたわみを強調したものである）、その割れにつながるおそれが小さい。 On the other hand, in FIG. 7, unlike the porcelain plate according to the present invention, the back legs 11 are provided at the same wide intervals in the peripheral portion of the drainage pipe through hole 13 and in the region other than the peripheral portion of the drainage pipe through hole 13. , It is a schematic diagram of a conventionally known ceramic plate. Further, in this embodiment, the through hole 14 for passing the fixing tool is originally located at the position where the back foot is present. Therefore, as in FIG. 6, when the fixing screw 8 is penetrated and hit against the floor surface 2 to fix the porcelain plate 1 and the drainage socket 7, the porcelain plate 1 is released by the stress from the fixing screw 8 as shown in FIG. Deflection (dotted line in the figure emphasizes deflection) and may lead to cracking in some cases. As shown in FIG. 6, in the porcelain plate according to the present invention, the stress from the fixing screw 8 has a small deflection of the porcelain plate 1 because the distance between the back legs is narrow (the dotted line in the figure is similarly the deflection. It is emphasized), and there is little risk of it leading to cracking.

本発明の一つの態様によれば、陶板には複数の排水管用貫通孔と、固定具用貫通孔とを備え、その結果、１枚で複数の便器の下に敷設できる大型または長尺の形状としてもよい。また、図３にあっては排水管用貫通孔と固定具用貫通孔とが一体化されて設けられた態様を示したが、これら排水管用貫通孔と固定具用貫通孔とは別々に独立ものとして設けられてもよい。 According to one aspect of the present invention, the porcelain plate is provided with a plurality of through holes for drainage pipes and through holes for fixtures, and as a result, a large or long shape that can be laid under a plurality of toilet bowls with one sheet. May be. Further, in FIG. 3, a mode in which the through hole for the drain pipe and the through hole for the fixture are integrally provided is shown, but the through hole for the drain pipe and the through hole for the fixture are separately and independently provided. It may be provided as.

本発明による陶板は、金型を使用したプレス成形により一般的には製造される。本発明による陶板にあっては、排水管用貫通孔の周辺部において、排水管用貫通孔周辺部以外の領域よりも、裏足同士の間隔が狭く配置された構造を有する。排水管用貫通孔および固定具用貫通孔は、陶板の成形後の加工により設けられることが好ましい。従って、陶板の成形にあたっては、排水管用貫通孔および固定具用貫通孔が設けられるであろう一定の領域において、裏足の間隔を狭くした構造とする。このような一定の領域において裏足の間隔を狭くしておくことで、多様な形状、構造の便器に、裏足の配置を変更させること無く対応でき、また陶板の軽量化と強度とを両立できる。
The ceramic plate according to the present invention is generally manufactured by press molding using a mold. The ceramic plate according to the present invention has a structure in which the distance between the hind legs is narrower in the peripheral portion of the through hole for drainage pipe than in the region other than the peripheral portion of the through hole for drainage pipe. It is preferable that the through hole for the drainage pipe and the through hole for the fixture are provided by processing after molding the ceramic plate. Therefore, when molding the porcelain plate, the structure is such that the distance between the back legs is narrowed in a certain area where the through hole for the drainage pipe and the through hole for the fixture will be provided. By narrowing the distance between the back legs in such a certain area, it is possible to handle toilet bowls of various shapes and structures without changing the arrangement of the back legs, and also to achieve both weight reduction and strength of the ceramic plate. can.
