Description

【０００１】
【発明の属する技術分野】
この発明は、無機質成形体及びその積み重ね方法に係り、特に屋根材や外壁材として使用し得る無機質成形体及び複数枚の無機質成形体をほぼ垂直に積み重ねる積み重ね方法に関する。
【０００２】
【従来の技術】
複数の瓦構成部を多行多列に一体成形して敷設作業の効率化を図ろうとする従来の屋根材を図１９に示す。この屋根材は、段差１を幅方向に設けて上段２と下段３との上下二段とし、下段３には幅方向中央に縦方向の一本の溝４を設けて二つの瓦構成部３ａ及び３ｂを形成し、上段２には下段３に対し一つの瓦構成部の半分だけ幅方向にずらして二本の溝５を設け、これらの溝５の間に一つの瓦構成部２ａを形成すると共にその幅方向両側にそれぞれ半分の幅の瓦構成部２ｂ及び２ｃを配置したものである。
【０００３】
図２０に示されるように、上段２の瓦構成部２ａ〜２ｃと下段３の瓦構成部３ａ及び３ｂは互いにほぼ等しい厚さを有しており、上段２の瓦構成部２ａ〜２ｃの下面が下段３の瓦構成部３ａ及び３ｂの上面とほぼ同じ高さになっている。
また、屋根材の裏面には複数のリブ６が形成されており、図２１に示されるように、複数枚の屋根材を積み重ねると、上に位置する屋根材のリブ６が下に位置する屋根材の瓦構成部の上面に当接し、平面ほぼ一致した状態で垂直方向に重ね積みされるようになっている。
【０００４】
【発明が解決しようとする課題】
しかしながら、複数枚の屋根材を積み重ねた場合の積み重ね高さＨは、各瓦構成部の厚さＤに積み重ねた屋根材の枚数Ｎを掛け合わせた値となり、各瓦構成部の厚さＤを厚く設計するほど積み重ね高さＨが高くなって、屋根材の保管及び流通作業性が低下するという問題がある。
また、図１９に示す屋根材を複数接合させて図２２のように施工すると、互いに幅方向に隣接する屋根材の間に縦方向の接合線７や隙間が現われるため、複数の瓦構成部を一体成形した屋根材であることが強調されて違和感を生じるという問題もある。
さらに、このような屋根材の製造時に、各瓦構成部の肉薄部分とリブが形成された肉厚部分とが混在する形状をプレス成型すると、肉厚のリブ部分の表面に充填不良によるクラックや気泡等の成型不良が生じ易くなってしまう。
【０００５】
この発明はこのような問題点を解消するためになされたもので、積み重ね高さを低く抑えることができる無機質成形体、及びその積み重ね方法を提供することを目的とする。
【０００６】
【課題を解決するための手段】
この発明に係る無機質成形体は、多行多列に複数の板材構成部が配列されて一体成形された無機質成形体であって、その裏面において互いに幅方向に隣接する板材構成部の境界部に縦方向に突設された補強リブを有すると共に、補強リブに対応するようにその表面において互いに幅方向に隣接する板材構成部の境界部に縦方向に形成された境界溝を有し、複数枚の無機質成形体をそれぞれ表面と裏面とが対向するように積み重ねたときに、上に位置する無機質成形体の補強リブがその下に位置する無機質成形体の境界溝の中に入り込むことにより一枚当たりの積み重ね厚さが無機質成形体一枚の厚さより小さくなるようにしたものである。
この無機質成形体は、窯業系建材として適用することができる。この場合、無機質成形体の表面において各板材構成部の幅方向中央部に縦方向の中央溝を形成することもできる。
【０００７】
また、境界溝を外側の溝とこの外側の溝の内部に形成された内側の溝とを有する少なくとも二段の溝から構成し、複数枚の無機質成形体を積み重ねたときに上に位置する無機質成形体の補強リブの下端部がその下に位置する無機質成形体の境界溝の内側の溝の中に嵌入するようにしてもよい。また、補強リブが、一条の縦方向のリブ本体と、このリブ本体の一部の上に形成された突出部とを有し、複数枚の無機質成形体を積み重ねたときに上に位置する無機質成形体の補強リブの突出部がその下に位置する無機質成形体の境界溝の上面に当接するようにしてもよい。
【０００８】
裏面の幅方向両端部にそれぞれ少なくとも一つの凸部を突設し、複数枚の無機質成形体を積み重ねたときにこの凸部が対向する無機質成形体の表面に当接するように構成することができる。また、表裏面の少なくとも一方に表面処理層を形成することもできる
この発明に係る無機質成形体の積み重ね方法は、請求項１〜７のいずれか一項に記載の無機質成形体を、互いに表面と裏面とが対向するように積み重ねる方法である。
【０００９】
【発明の実施の形態】
以下、この発明の実施の形態を添付図面に基づいて説明する。
実施の形態１．
図１〜５にこの発明の実施の形態１に係る屋根材を示す。この屋根材は、無機材料から一体成形されたほぼ四角形をなす板形状を有し、段差１１を幅方向に設けて上段１２と下段１３との上下二段としたものである。下段１３には４つの瓦構成部１３ａ〜１３ｄが均等に横方向に配列され、上段１２には下段１３に対して一つの瓦構成部の半分だけ幅方向にずらして３つの瓦構成部１２ａ〜１２ｃが配列されると共にその幅方向両側にそれぞれ半分の幅の瓦構成部１２ｄ及び１２ｅが配置されている。
【００１０】
互いに幅方向に隣接する瓦構成部の境界部には、それぞれ縦方向に沿って境界溝１４が形成され、各瓦構成部の幅方向中央部には縦方向に沿って中央溝１５が形成されている。
図１において、上段１２及び下段１３の左側部には左側に隣接する屋根材との接合用の葺合わせ部１６が延設されており、この葺合わせ部１６の表面上に上段１２及び下段１３にそれぞれ対応して凹部１７及び１８が形成されている。また、上段１２の上縁部には上側に隣接する屋根材との接合用の葺合わせ部１９が延設されており、この葺合わせ部１９に複数の取付孔２０が設けられている。
【００１１】
図２に示す屋根材の裏面において、葺合わせ部１６に隣接して凸部２１及び２２が突設されると共に、葺合わせ部１６とは反対側の側端部にも凸部２３及び２４が突設されている。
【００１２】
図３及び４に示されるように、上段１２と下段１３は互いにほぼ等しい厚さを有しており、上段１２の瓦構成部１２ａ〜１２ｅの下面が下段１３の瓦構成部１３ａ〜１３ｄの上面とほぼ同じ高さになっている。
図５（ａ）及び（ｂ）に示されるように、境界溝１４は、外側の曲面状の溝１４ａと、この外側の溝１４ａの内部に形成された内側の曲面状の溝１４ｂとを備えた二段の溝からなっている。
また、図６に示されるように、屋根材の裏面において、互いに幅方向に隣接する瓦構成部の境界部には、縦方向に補強リブ２５が突設されている。この補強リブ２５は、一条の縦方向のリブ本体２６と、リブ本体２６の一部の上に形成されたほぼ矩形の平面状の底面を有する突出部２７とを含んでいる。
【００１３】
このような構造を有する実施の形態１の屋根材を二枚積み重ねると、図７（ａ）に示されるように、上側に位置する屋根材裏面の補強リブ２５の突出部２７が下側に位置する屋根材表面の境界溝１４の外側の溝１４ａの上面に当接すると共に、屋根材の両側端部において上側の屋根材裏面の凸部２１〜２４が下側の屋根材の表面に当接し、これにより平面ほぼ一致した状態でしっかりと重ね積みされる。このとき、上側の屋根材の補強リブ２５の一部が下側の屋根材表面の境界溝１４の中に入り込むため、図７（ｂ）に示されるように、二枚の屋根材の積み重ね高さｈは、各瓦構成部の厚さｄの二倍より小さくなっている。すなわち、複数枚の屋根材を積み重ねた場合に、一枚当たりの積み重ね厚さが各瓦構成部の厚さｄより小さくなり、このため、屋根材の保管及び流通作業性が向上する。
また、複数枚の屋根材を積み重ねた場合に、屋根材の両側端部において上側の屋根材裏面の凸部２１〜２４が下側の屋根材の表面に当接するので、積み重ねた状態でロープやテープを幅方向に巻回することにより、各屋根材の端部に不必要な応力を与えることなく束ねることができ、保管や運搬が容易となる。
【００１４】
実施の形態１の屋根材を複数組み合わせて施工した状態を図８（ａ）及び（ｂ）に示す。図８（ａ）は縦方向に接する屋根材が互いに幅方向に同じ位置となるように幅方向の位相を合致させて組み合わせた状態、図８（ｂ）は縦方向に接する屋根材が互いに全長の半分だけ幅方向にずれるように千鳥状に組み合わせた状態を示している。各瓦構成部の幅方向中央部に縦方向に沿って中央溝１５が形成されているため、図８（ａ）及び図８（ｂ）いずれの場合においても、施工により幅方向に隣接する屋根材との接合部に生じる縦方向の接合線２８は、見かけ上中央溝１５と極めて類似し、複数の瓦構成部の一体成形体であることが目立たず、あたかも各瓦構成部ごとに施工したような外観が与えられて違和感が生じない。
【００１５】
互いに幅方向に隣接する組み合わせ部分においては、図９に示されるように、一方の屋根材の裏面の凸部２３及び２４が他方の屋根材の葺合わせ部１６の凹部１７及び１８にそれぞれ嵌合し、これにより屋根材と屋根材との位置ずれが防止される。
【００１６】
なお、屋根材の裏面において補強リブ２５が突設される箇所には、その表面側に境界溝１４が形成されるので、この補強リブ部分の厚さを小さく抑えることができ、このため屋根材の製造時に、各瓦構成部の肉薄部分と補強リブが形成された肉厚部分とが混在する形状をプレス成型しても、充填不良による成型不良を生じず、優れた強度及び成型性が得られる。
【００１７】
実施の形態２．
図１０〜１４にこの発明の実施の形態２に係る屋根材を示す。この屋根材は、実施の形態１に係る屋根材において、互いに幅方向に隣接する瓦構成部の境界部の、表面側に形成された縦方向の境界溝１４及び裏面側に突設された縦方向の補強リブ２５の代わりに、形状の異なる境界溝３１及び補強リブ３２を設けたものであり、他の構成は実施の形態１の屋根材と同様である。
【００１８】
屋根材の表面に形成された境界溝３１は、外側の平面状の溝３１ａと、この外側の溝３１ａの内部に形成された内側の平面状の溝３１ｂとを備えた二段の溝からなっている。
これに対して、屋根材の裏面に突設された補強リブ３２は、図１５及び図１６（ｂ）に明確に示されるように、縦方向に直線状に形成されたリブ本体３３と、このリブ本体３３の下端にさらに直線状に突設された突出部３４とからなっている。
【００１９】
このような構造を有する実施の形態２の屋根材を二枚積み重ねると、図１６（ａ）及び（ｂ）に示されるように、上側に位置する屋根材裏面の補強リブ３２のリブ本体３３の下面が下側に位置する屋根材表面の境界溝３１の外側の溝３１ａの上面に当接すると共に、上側の屋根材の補強リブ３２の突出部３４が下側の屋根材の境界溝３１の内側の溝３１ｂ内に嵌入され、これにより平面ほぼ一致した状態でしっかりと重ね積みされ且つ横ずれを生じる惧れがなくなる。
【００２０】
このとき、上側の屋根材の補強リブ３２の一部が下側の屋根材表面の境界溝３１の中に入り込むため、実施の形態１と同様に、図１６（ｃ）に示されるように、二枚の屋根材の積み重ね高さｈは、各瓦構成部の厚さｄの二倍より小さくなっている。すなわち、複数枚の屋根材を積み重ねた場合に、一枚当たりの積み重ね厚さが各瓦構成部の厚さｄより小さくなり、このため、屋根材の保管及び流通作業性が向上する。
【００２１】
また、実施の形態１と同様に、積み重ねた状態でロープやテープを幅方向に巻回することにより、各屋根材の端部に不必要な応力を与えることなく束ねることができ、保管や運搬が容易となる。
各瓦構成部の幅方向中央部に縦方向に沿って中央溝１５が形成されているため、施工により幅方向に隣接する屋根材との接合部に生じる縦方向の接合線は、見かけ上中央溝１５と極めて類似し、複数の瓦構成部の一体成形体であることが目立たず、あたかも各瓦構成部ごとに施工したような外観が与えられて違和感が生じない。
さらに、屋根材の裏面において補強リブ３２が突設される箇所には、その表面側に二段の境界溝３１が形成されるので、この補強リブ部分の厚さを小さく抑えることができ、このため屋根材の製造の際に脱水成型しても、充填不良による成型不良を生じず、優れた強度及び成型性が得られる。
【００２２】
実施の形態３．
図１７及び１８にこの発明の実施の形態３に係る屋根材を示す。この屋根材は、実施の形態２に係る屋根材において、互いに幅方向に隣接する瓦構成部の境界部の、表面側に形成された縦方向の境界溝３１の代わりに、境界溝４１を形成したものである。
【００２３】
屋根材の表面に形成された境界溝４１は、縦方向の平面状の一段のみの溝からなっている。この実施の形態３の屋根材を二枚積み重ねると、図１８（ａ）及び（ｂ）に示されるように、上側に位置する屋根材裏面の補強リブ３２の下面が下側に位置する屋根材表面の境界溝４１の上面に当接し、これにより平面ほぼ一致した状態でしっかりと重ね積みされる。
【００２４】
このとき、上側の屋根材の補強リブ３２の一部が下側の屋根材表面の境界溝４１の中に入り込むため、実施の形態１及び２と同様に、図１８（ｂ）に示されるように、屋根材一枚当たりの積み重ね厚さが各瓦構成部の厚さより小さくなり、このため、屋根材の保管及び流通作業性が向上する。
【００２５】
なお、図１７に示した屋根材では、各瓦構成部の幅方向中央部に縦方向の中央溝が形成されていないため、施工により幅方向に隣接する屋根材との接合部に縦方向の隙間が形成されると、複数の瓦構成部の一体成形体であることが目立ってしまうが、実施の形態１及び２と同様に各瓦構成部の幅方向中央部に縦方向の中央溝を形成することにより、あたかも各瓦構成部ごとに施工したような外観を与えることが可能である。
【００２６】
なお、上述した実施の形態１〜３において、無機質成形体からなるの屋根材の表裏面の少なくとも一方に表面処理層を形成することもできる。
実施の形態１〜３では、屋根材について述べたが、この発明は屋根材に限るものではなく、同様の構造の外壁材を形成することもでき、窯業系建材等に幅広く適用することが可能である。
【００２７】
【発明の効果】
以上説明したように、この発明によれば、多行多列に複数の板材構成部が配列されて一体成形された無機質成形体の裏面において互いに幅方向に隣接する板材構成部の境界部に縦方向に補強リブを突設すると共に、補強リブに対応するようにその表面において互いに幅方向に隣接する板材構成部の境界部に縦方向に境界溝を形成し、複数枚の無機質成形体をそれぞれ表面と裏面とが対向するように積み重ねたときに、上に位置する無機質成形体の補強リブがその下に位置する無機質成形体の境界溝の中に入り込むことにより一枚当たりの積み重ね厚さが無機質成形体一枚の厚さより小さくなるようにしたので、無機質成形体の保管及び流通作業性の向上を図ることができる。
また、積み重ねた状態でロープやテープを幅方向に巻回することにより、各無機質成形体の端部に不必要な応力を与えることなく束ねることができ、保管や運搬が容易となる。
各板材構成部の幅方向中央部に縦方向に沿って中央溝を形成すれば、施工により幅方向に隣接する無機質成形体との接合部に生じる縦方向の接合線は、見かけ上中央溝と類似し、複数の板材構成部の一体成形体であることが目立たず、あたかも各板材構成部ごとに施工したような外観が与えられて違和感が生じない。
さらに、裏面に補強リブを突設すると共にその突設箇所の表面側に境界溝を形成して、補強リブ部分の厚さを小さく抑えれば、無機質成形体の製造の際に脱水成型しても、充填不良による成型不良を生じず、優れた強度及び成型性が得られる。

Recesses 17 and 18 are formed corresponding to the above. In addition, an upper edge portion of the upper stage 12 is extended with a joining portion 19 for joining to the roof material adjacent to the upper side, and the fitting portion 19 is provided with a plurality of attachment holes 20.
[0011]
On the back surface of the roofing material shown in FIG. 2, convex portions 21 and 22 are provided so as to protrude adjacent to the mating portion 16, and convex portions 23 and 24 are also formed on the side end opposite to the mating portion 16. Projected.
[0012]
As shown in FIGS. 3 and 4, the upper stage 12 and the lower stage 13 have substantially the same thickness, and the lower surfaces of the roof constituent parts 12 a to 12 e of the upper stage 12 are the upper surfaces of the roof constituent parts 13 a to 13 d of the lower stage 13. It is almost the same height.
As shown in FIGS. 5A and 5B, the boundary groove 14 includes an outer curved groove 14a and an inner curved groove 14b formed inside the outer groove 14a. It consists of two tiered grooves.
In addition, as shown in FIG. 6, reinforcing ribs 25 protrude in the vertical direction at the boundary between the tile constituent portions adjacent to each other in the width direction on the back surface of the roof material. The reinforcing rib 25 includes a single longitudinal rib body 26 and a protrusion 27 having a substantially rectangular flat bottom formed on a part of the rib body 26.
[0013]

Such an appearance is given, and a strange feeling does not occur.
[0015]
In the combination portion adjacent to each other in the width direction, as shown in FIG. 9, the convex portions 23 and 24 on the back surface of one roof material are fitted into the concave portions 17 and 18 of the mating portion 16 of the other roof material, respectively. Thus, positional deviation between the roofing material and the roofing material is prevented.
[0016]
In addition, since the boundary groove 14 is formed in the surface side in the location where the reinforcement rib 25 protrudes in the back surface of the roof material, the thickness of this reinforcement rib part can be restrained small, therefore roof material Even when press-molding a shape in which the thin part of each tile component and the thick part where the reinforcing rib is formed are press-molded at the time of manufacturing, there is no molding failure due to poor filling, and excellent strength and moldability are obtained. It is done.
[0017]
Embodiment 2. FIG.
10 to 14 show a roof material according to Embodiment 2 of the present invention. In the roof material according to the first embodiment, the roof material is a vertical boundary groove 14 formed on the front surface side of the boundary portion between the tile constituent portions adjacent to each other in the width direction, and the vertical protrusion projecting on the back surface side. Instead of the reinforcing ribs 25 in the direction, boundary grooves 31 and reinforcing ribs 32 having different shapes are provided, and other configurations are the same as those of the roofing material of the first embodiment.
[0018]
The boundary groove 31 formed on the surface of the roofing material is a two-stage groove including an outer planar groove 31a and an inner planar groove 31b formed inside the outer groove 31a. ing.
On the other hand, the reinforcing ribs 32 projecting from the back surface of the roofing material, as clearly shown in FIG. 15 and FIG. The rib main body 33 includes a projecting portion 34 that further projects linearly at the lower end.
[0019]
When two roof materials of Embodiment 2 having such a structure are stacked, as shown in FIGS. 16A and 16B, the rib main body 33 of the reinforcing rib 32 on the back surface of the roof material located on the upper side. The lower surface is in contact with the upper surface of the outer groove 31a of the boundary groove 31 on the surface of the roofing material, and the protrusion 34 of the reinforcing rib 32 of the upper roofing material is inside the boundary groove 31 of the lower roofing material. So that they can be firmly stacked in a state where the planes substantially coincide with each other and there is no possibility of causing lateral displacement.
[0020]
At this time, since a part of the reinforcing rib 32 of the upper roof material enters the boundary groove 31 on the lower roof material surface, as in the first embodiment, as shown in FIG. The stacking height h of the two roofing materials is smaller than twice the thickness d of each tile component. That is, when a plurality of roof materials are stacked, the stack thickness per sheet becomes smaller than the thickness d of each tile constituent part, and thus the storage and workability of the roof materials are improved.
[0021]
Moreover, like Embodiment 1, it can be bundled without giving unnecessary stress to the edge part of each roof material by winding a rope or a tape in the width direction in the stacked state, and storing and carrying Becomes easy.
Since the central groove 15 is formed along the vertical direction in the central portion in the width direction of each tile-constituting portion, the vertical joining line generated at the joint portion with the roof material adjacent in the width direction by construction is apparently the center. It is very similar to the groove 15 and it is not conspicuous that it is an integrally formed body of a plurality of tile constituent parts, and an appearance as if it was constructed for each tile constituent part is given, so that a sense of incongruity does not occur.
Furthermore, since the two-step boundary groove 31 is formed on the surface side of the portion where the reinforcing rib 32 protrudes on the back surface of the roofing material, the thickness of the reinforcing rib portion can be kept small. Therefore, even if dehydration molding is performed during the production of the roofing material, molding strength due to poor filling does not occur, and excellent strength and moldability can be obtained.
[0022]
Embodiment 3 FIG.
17 and 18 show a roofing material according to Embodiment 3 of the present invention. In the roof material according to the second embodiment, this roof material forms a boundary groove 41 instead of the vertical boundary groove 31 formed on the surface side of the boundary portions of the tile constituent parts adjacent to each other in the width direction. It is a thing.
[0023]
The boundary groove 41 formed on the surface of the roof material is a single flat groove in the vertical direction. When two roof materials according to the third embodiment are stacked, as shown in FIGS. 18A and 18B, the lower surface of the reinforcing rib 32 on the back surface of the roof material located on the upper side is located on the lower side. It abuts against the upper surface of the boundary groove 41 on the surface, and is thereby firmly stacked in a state where the planes substantially coincide.
[0024]
At this time, since a part of the reinforcing rib 32 of the upper roof material enters the boundary groove 41 on the surface of the lower roof material, as in the first and second embodiments, as shown in FIG. In addition, the stacking thickness per roofing material is smaller than the thickness of each tile component, so that the storage and distribution workability of the roofing material is improved.
[0025]
In addition, in the roof material shown in FIG. 17, since the vertical center groove | channel is not formed in the width direction center part of each tile structure part, it is vertical at the junction part with the roof material adjacent to the width direction by construction. When the gap is formed, it is conspicuous that it is an integrally formed body of a plurality of tile constituent parts. However, as in the first and second embodiments, a central groove in the vertical direction is formed in the central part in the width direction of each tile constituent part. By forming, it is possible to give the appearance as if it were constructed for each tile component.
[0026]
In the first to third embodiments described above, a surface treatment layer may be formed on at least one of the front and back surfaces of the roof material made of an inorganic molded body.
In the first to third embodiments, the roof material has been described. However, the present invention is not limited to the roof material, and an outer wall material having a similar structure can be formed, and can be widely applied to ceramic building materials. It is.
[0027]
【The invention's effect】
As described above, according to the present invention, a plurality of plate member constituent portions are arranged in multiple rows and multiple columns and are integrally formed on the rear surface of the inorganic molded body so as to be vertically aligned with the boundary portions of the plate member constituent portions adjacent to each other in the width direction. In addition to projecting reinforcing ribs in the direction, boundary grooves are formed in the longitudinal direction at the boundary portions of the plate material constituent parts adjacent to each other in the width direction so as to correspond to the reinforcing ribs, and a plurality of inorganic molded bodies are respectively formed. When the front and back surfaces are stacked so that they face each other, the reinforcing ribs of the inorganic molded body positioned above enter the boundary groove of the inorganic molded body positioned below, so that the stacked thickness per sheet is reduced. Since the thickness is smaller than the thickness of one inorganic molded body , it is possible to improve the storage and distribution workability of the inorganic molded body .
Moreover, by winding a rope or a tape in the width direction in a stacked state, it can be bundled without applying unnecessary stress to the end of each inorganic molded body , and storage and transportation are facilitated.
If a central groove is formed along the vertical direction in the central part in the width direction of each plate member constituting part, the vertical joining line generated in the joint part with the inorganic molded body adjacent in the width direction by construction is apparently the central groove. Similarly, it is not conspicuous that it is an integrally formed body of a plurality of plate member constituent parts, and an appearance as if it was constructed for each plate member constituent part is given, and a sense of incongruity does not occur.
Furthermore, if a reinforcing rib is protruded on the back surface and a boundary groove is formed on the surface side of the protruding portion, and the thickness of the reinforcing rib portion is kept small, dewatering molding is performed during the production of the inorganic molded body. However, it does not cause molding failure due to poor filling, and excellent strength and moldability can be obtained.
