Description

【０００１】
【発明の属する技術分野】
この発明は、外壁材の受け材に関し、詳しくは壁板を壁下地材に金具で固定する際にその壁板の下端を支持する受け材の改良に関する。
【０００２】
【従来の技術】
従来、繊維補強セメント製壁板などの窯業系壁板を留め付ける受け材として、図１０に示すような外壁材の受け材１が一般に使用されていた。
この外壁材の受け材１は、胴縁や柱などの壁下地材２（図示例は胴縁）に沿う縦片１ａと壁板３を受ける横片１ｂを備え、釘やビス等の固定具４で縦片１ａを下地材２に固定し、横片１ｂ上面に壁板３下端を載置するようにして使用されるが、横片１ｂと壁板下端面との接触面、あるいは縦片１ａと壁板背面３ａとの間に毛細管現象により雨水が滞留、浸透し易く、壁板３を湿らせた状態とするのを防止する観点から図示のように排水孔１ｃを設け、あるいは縦片１ａや横片１ｂ表面間に隙間を形成するためのリブ５、５を形成することが行なわれている。
【０００３】
【発明が解決しようとする課題】
しかし、上記外壁材の受け材１において、壁板３裏面３ａとの隙間を形成するリブ５は、縦片１ａ表面から直立する断面で形成されていたため、壁板３を外壁材の受け材１上に据え付ける際、図１１に示すように壁板下端３ｂを引っかけてしまうことがあり、このためリブ５を破断したりあるいは壁板裏面３ｂを欠損させたりすることがある問題があった。
【０００４】
また、横片１ｂに排水溝１ｃを設けるのはそれだけ工数が掛かり製造が面倒となる問題があった。
また、壁板３を外壁材の受け材１上に据えたあと固定するまでの間、壁板３が外壁材の受け材１上で自立状態を維持することが好ましいが、従来の外壁材の受け材１は横片１ｂの壁板下端面に対する接触面の状態が必ずしも自立状態を維持できるようにされておらず、ともすれば壁板３が図１０に矢印Ｐで示したように表面側へ倒れ勝手になる場合もあり、仮支持のために何らかの手段を必要とし施工に手間がかかるといった問題があった。
【０００５】
さらに、釘などによる止着部が縦片の略中間部とされているので、止着部４より下端までの距離ｈが短く、止着部４を中心とした矢印Ｍ方向の回転抵抗モーメントが弱いので、止着部４に強大な引き抜き力が作用し、壁板を完全固定するまでに釘などが緩み易い問題があった。
この発明は上記問題点を解消することを目的としてなされたものであり、壁板を固定する受け材の壁板に対する良好な接触性や施工性、並びに十分な耐水性を同時に兼ね備えた外壁材の受け材を得ることを課題としてなされたものである。
【０００６】
【課題を解決するための手段】
上記目的を達成するため、請求項１の外壁材の受け材は、壁板裏面に沿う縦片と、壁板下端に沿う横片とが一体成形され、前記縦片の上縁に下方へ向け次第に壁板表面側へ張り出す傾斜面が形成され、該傾斜面の下方に凹入部が形成され、前記横片の壁板厚さ方向の延出距離が壁板厚さの半分より大きく壁板厚さ以下とされ、この横片の延出端に沿ってリブ状の突起が形成され、横片の上面は縦片方向へ向け下方傾斜する傾斜面とされ、かつこの傾斜面の谷部に貫通孔が穿設されてなる。
【０００７】
この外壁材の受け材によれば、外壁材を据え付ける際、壁板下端面が外壁材の受け材の縦片に当接することがあっても、傾斜面によって滑らかに受け流されるので衝突しても凸部が壊れたり、壁板下面が欠損したりすることがない。
また、壁板下端を支持するリブ状突起は、必ず壁板表面側の下端面を下方から支持することとなるので、壁板を外壁材の受け材上に立てかけた時壁板には必ず裏面側へ倒れ掛かるモーメントが生じ、表面側へ倒れるのが防止される。従って、壁板固定までの仮支持が容易となる。
また、壁板下端面は横片のリブ状突起で受けられるので線的な接触となり毛細管現象による雨水浸透がなく、雨水が流入しても貫通孔から排出される。
【０００８】
請求項２の外壁材の受け材は、上記外壁材の受け材において、縦片の凹入部底面に固定具挿通用の貫通孔が成形されたものである。
従って、この発明によれば止着釘やビスなどの頭が凹入部に隠され、壁板端面とこれら止着具の頭部との引っ掛かりが防止される。
請求項３の外壁材の受け材は、上記外壁材の受け材において横片が縦片の裏面側へ凹入部底面裏面と同一面となるよう延出され、該延出端が支持基面に当接する平坦面とされたものである。
【０００９】
この発明によれば、外壁材の受け材に壁板の荷重が加わっても横片の裏面側への延出片が平坦面を介して当接するので、支持が安定する。
【００１２】
【実施の形態】
次にこの発明の実施の形態を説明する。
実施の形態１
図１はこの発明の実施の形態である外壁材の受け材の断面図、図２は正面図である。
【００１３】
図１において１１はこの発明の外壁材の受け材を示し、壁板３裏面３ａに沿う縦片１１ａと、壁板３の端面３ｂを受ける横片１１ｂとがアルミ軽合金の引き抜き成形体や鋼板、ステンレス鋼板の打ち抜きプレス成形のような成形法により一体成形され、縦片１１ａの上縁に下方へ向け次第に壁板表面側へ張り出す傾斜面１２が形成され該傾斜面１２の下方に、凹入部１３が形成されて前記横片に一体的に接合されている。
【００１４】
なお、上記において、凹入部１３の凹入量は傾斜面の張り出た距離ｔに等しい凹入量とされている。
また、横片１１ｂには壁板３の端面３ｂに当接するリブ状の凸部１４が形成され、さらに横片１１ｂの上面は縦片１１ａ方向へ向け下方傾斜する傾斜面１５とされ、かつこの傾斜面１５の谷部１５ａに貫通孔１６が穿設されて構成されている。
【００１５】
なお、この貫通孔１６は必要に応じ形成され、壁板３の接合段部などから侵入した雨水が上記横片１１ｂ上に流下する場合に設けられる。また、１７は止着釘やビスなどの固定具４挿通用の貫通孔を示す。
次に上記外壁材の受け材１１の使用状態について説明する。
図３は外壁材の受け材に壁板を支持させた状態を示す断面図である。
【００１６】
外壁材の受け材１１は、縦片１１ａの上辺部で貫通孔１７を挿通した固定具４で柱や胴縁などの壁下地材２に固定される。
壁板３は、裏面３ａを縦片１１ａに沿わせ、また下端３ｂが横片１１ｂのリブ状の凸部１４上に載置されて支持される。
このとき、縦片１１ａは上辺部に傾斜面１２が形成されているので、据え付け時、壁板３の下端が傾斜面１２に衝突することがあっても矢印Ｑ、Ｑで示すように斜め方向に受け流され、壁板下端３ｂが損傷するのが防止される。
【００１７】
凹入部１３の下方側面を図示のように傾斜面とした場合、この部分についても同様に衝突による損傷が防止される。
また、据え付け後の壁板３裏面は傾斜面１２の張り出た頂点部分１２ａで、また下端面は凸状部１４で線的に支持されるので毛細管現象による雨水の浸透がなく、仮に侵入することがあっても横片１１ｂの貫通孔１６から排出されるので水捌けが良い。なお、横片１１ｂの表面は下方傾斜する傾斜面１５とされ、谷部１５ａが形成されているので貫通孔１６からの排出性も良くされる。
【００１８】
実施の形態２
図４は実施の形態２の断面図である。
なお、図４において図１〜３と同じ符号は同一部材または相当する部材を示すので、これら部材に関しては同一符号を付すのみで詳細な説明は省略する。
この実施の形態２の外壁材の受け材１１は、縦片１１ａに設けられる固定具挿通用の貫通孔１７が、凹入部１３の底面１３ａに設けられている。
【００１９】
従って、図示のように外壁材の受け材１１を下地材２に固定した場合、釘やビスなどの固定具４の頭部４ａが凹入部１３内部に隠れてしまうので、壁板３の設置時にこれらとの衝突を避けることができる。
実施の形態３
この実施の形態３の外壁材の受け材１１は、図１〜図４に示したように、横片１１ｂが縦片１１ａ裏面側へ、凹入部１３の底面裏面と同一面となるよう延出され、この延出端１１ｃが柱や胴縁等の支持基面２に対する平坦面とされて構成されている。
【００２０】
この平坦面は図示のように延出端にＴ字状またはＬ字状に交差する支持片１８を一体形成することにより成形される。
この実施の形態３の外壁材の受け材１１は、固定具１７の止着部を中心とする壁板荷重による回転モーメントに対し、支持片１８が広い面積で基面２に接触して対抗するので対抗モーメントを大きくすることができ、また単位当たりの面厚も低くできるので下地材を傷めることもない。
【００２１】
実施の形態４
図５は実施の形態４の断面図、図６は同底面図である。
なお、図５、図６において図１〜３と同じ符号は同一部材または相当する部材を示すので、これら部材に関しては同一符号を付すのみで詳細な説明は省略する。
【００２２】
この実施の形態４の外壁材の受け材１１は、図５、図６に示すように横片１１ｂの壁板３の厚さ方向の延出距離Ｌが壁板接合部３ａの防水シール部３ｂに達しない距離とされ、該横片１１ｂの延出端に沿ってリブ状の凸部１４が形成されてなる。
従って、壁板接合部３ａの防水シール部３ｂより壁板表面側には雨水が浸透するが、横片１１ｂはこのシール部３ｂより壁板裏面側となるので、侵入した雨水は横片１１ｂ上に流入することが無い。
【００２３】
従って、横片１１ｂ表面に排水用の貫通孔を設ける必要が無くなり、その分製造が容易となる。
図７は実施の形態５の断面図である。
なお、図７において図１〜３と同じ符号は同一部材または相当する部材を示すので、これら部材に関しては同一符号を付すのみで詳細な説明は省略する。
【００２４】
この実施の形態４の外壁材の受け材１１は、図７に示すように横片１１ｂの壁板３の厚さ方向の延出距離Ｌが壁板３の厚さＴに対し厚さＴ以下で半分の厚さより大、即ちＴ≧Ｌ＞Ｔ／２とされている。
従って、凸状部１４上に壁板端面を載置したとき、壁板３は矢印Ｒで示すように常に背面側に倒れ勝手となり、固定するまでの壁板の自立性が良くなり、施工性がよくなる。
【００２５】
上記実施の形態１〜５として、縦片１１ａの形状について上縁を傾斜面１２、それより下方を方形の凹入部１３としこの凹入部１３の下方側壁を同様な傾斜面とした場合を示したが、図８（ａ）〜（ｃ）に示すような断面形状としても良い。
また、この発明の外壁材の受け材１１は図２に示したように、例えば３ｍの長尺物とし、壁基面に沿って固定具により取り付けるようにする他、図９に示すように要所要所に取り付ける止着金具のようにして使用しても良い。
【００２６】
また、材質として、アルミ軽合金による引き抜き成形等の場合を説明したが、金属板、薄金属板の折曲成形、硬質プラスチックに押出成形等であっても成形可能である。
【００２７】
【発明の効果】
以上説明したように、この発明の外壁材の受け材によれば、縦片上縁の突起の上縁が傾斜面とされているので据え付け中の壁板が衝突しても両者が傷つくことがなく、安全に据え付け作業をすることができる。
また、縦片、横片と壁板裏面、端面との間に十分な隙間が形成されるので水切り性が良く、雨水の毛細管現象による浸透もない。
【００２８】
また、壁板を支持した場合の横片の基面に対する接触圧力が小さくできるので壁板の支持安定性が良く、柱や胴縁を使用した場合の支持力を安定したものにすることができる。
さらに、壁板端面の支持箇所を壁板端面の表面側としているので、横片上に壁板を載置したとき、裏面側へ倒れ勝手となり、仮支持が容易となる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a receiving material for an outer wall material, and more particularly, to an improvement in a receiving material for supporting a lower end of a wall plate when the wall plate is fixed to a wall base material with metal fittings.
[0002]
[Prior art]
Conventionally, as a receiving member for fastening a ceramic wall plate such as a fiber-reinforced cement wall plate, a receiving member 1 of an outer wall material as shown in FIG. 10 has been generally used.
The receiving material 1 of the outer wall material includes a vertical piece 1a along a wall base material 2 (a body edge in the illustrated example) such as a body edge and a pillar, and a horizontal piece 1b for receiving a wall plate 3, and a fixing tool such as a nail or a screw. 4, the vertical piece 1a is fixed to the base material 2 and the lower end of the wall plate 3 is placed on the upper surface of the horizontal piece 1b. The contact surface between the horizontal piece 1b and the lower end face of the wall plate or the vertical piece is used. A drain hole 1c is provided as shown in the drawing from the viewpoint of preventing the rain water from easily staying and permeating due to a capillary phenomenon between the wall plate 1a and the rear surface 3a and preventing the wall plate 3 from being moistened. Forming ribs 5, 5 for forming a gap between the surfaces of 1a and the horizontal piece 1b is performed.
[0003]
[Problems to be solved by the invention]
However, since the ribs 5 forming the gaps with the back surface 3a of the wall plate 3 in the receiving material 1 of the outer wall material are formed in a cross-section that is erected from the surface of the vertical piece 1a, the wall plate 3 is attached to the receiving material 1 of the outer wall material. At the time of installation on the upper side, as shown in FIG. 11, the lower end 3b of the wall plate may be hooked, and thus the ribs 5 may be broken or the back surface 3b of the wall plate may be broken.
[0004]
In addition, the provision of the drain groove 1c in the horizontal piece 1b has a problem that the number of steps is increased and the production is troublesome.
In addition, it is preferable that the wall plate 3 be kept in an independent state on the outer wall material receiving member 1 until the wall plate 3 is fixed after being set on the outer wall material receiving member 1. The receiving member 1 does not necessarily maintain the state of the contact surface of the horizontal piece 1b with the lower end surface of the wall plate, so that the wall plate 3 is positioned on the front side as shown by the arrow P in FIG. There was a problem that some kind of means was required for temporary support and construction was troublesome.
[0005]
Furthermore, since the fastening portion such as a nail is formed at a substantially middle portion of the vertical piece, the distance h from the fastening portion 4 to the lower end is short, and the rotational resistance moment in the direction of arrow M around the fastening portion 4 is reduced. Since it is weak, a strong pulling force acts on the fastening portion 4, and there is a problem that the nails and the like are easily loosened before the wall plate is completely fixed.
The present invention has been made for the purpose of solving the above problems, and has excellent contact and workability of a receiving material for fixing a wall plate to a wall plate, and an outer wall material having both sufficient water resistance at the same time. The task was to get the receiving material.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, in the receiving material for the outer wall material according to claim 1, a vertical piece along the back surface of the wall board and a horizontal piece along the lower end of the wall board are integrally formed, and are directed downward to the upper edge of the vertical piece. gradually formed inclined surfaces projecting into the wall plate surface side, recessed portion is formed below the inclined surface, extending a distance of the wall thickness direction of the crosspiece is greater than half the wall thickness of the wall plate The thickness is not more than a thickness, a rib-like projection is formed along the extending end of the horizontal piece, and the upper surface of the horizontal piece is an inclined surface inclined downward in the vertical direction, and at the valley of the inclined surface. A through hole is formed.
[0007]
According to the receiving material of the outer wall material, when the outer wall material is installed, even if the lower end surface of the wall plate abuts against the vertical piece of the receiving material of the outer wall material, it is smoothly parryed by the inclined surface so that the collision occurs. Also, the projections are not broken and the lower surface of the wall plate is not broken.
In addition, the rib-shaped projections supporting the lower end of the wall plate always support the lower end surface on the surface side of the wall plate from below, so when the wall plate is leaned on the receiving material of the outer wall material, the wall plate always has the back surface. A moment of leaning to the side is generated, and it is prevented from falling to the surface side. Therefore, temporary support up to fixing the wall plate is facilitated.
Furthermore, the wall plate lower surface because it is received by the rib-like projections of the horizontal piece rainwater penetration rather name by capillary phenomenon becomes a line contact, also flows into the rain water is discharged from the through hole.
[0008]
According to a second aspect of the present invention, in the receiving member for the outer wall material, a through hole for inserting a fixture is formed on the bottom surface of the recessed portion of the vertical piece.
Therefore, according to the present invention, the heads of the fixing nails and screws are hidden in the recessed portions, and the end face of the wall plate and the heads of these fixing devices are prevented from being caught.
In the receiving material for the outer wall material according to claim 3, the horizontal piece is extended to the back surface side of the vertical piece in the receiving material for the outer wall material so as to be flush with the bottom surface of the recessed portion, and the extended end is provided on the support base surface. It is a flat surface that comes into contact.
[0009]
According to the present invention, the extending piece on the back side of the crosspiece even when a load is applied in the wall plate to the receiving material of the outer wall member abuts via a flat surface, the support is you stable.
[0012]

[0013]
In FIG. 1, reference numeral 11 denotes a receiving material for an outer wall material according to the present invention, wherein a vertical piece 11a along the back surface 3a of the wall plate 3 and a horizontal piece 11b for receiving the end surface 3b of the wall plate 3 are formed by a drawn aluminum alloy or steel plate. An inclined surface 12 is formed integrally with the upper edge of the vertical piece 11a by a forming method such as stamping press forming of a stainless steel plate, and is gradually downwardly projecting toward the surface of the wall plate. An insertion portion 13 is formed and integrally joined to the horizontal piece.
[0014]
In the above description, the recess amount of the recess portion 13 is set to the recess amount equal to the protruding distance t of the inclined surface.
Also, a rib-shaped convex portion 14 is formed on the horizontal piece 11b to be in contact with the end face 3b of the wall plate 3, and the upper surface of the horizontal piece 11b is formed as an inclined surface 15 inclined downward toward the vertical piece 11a. A through hole 16 is formed in a valley 15 a of the inclined surface 15.

The wall plate 3 has the back surface 3a along the vertical piece 11a, and the lower end 3b is placed and supported on the rib-shaped convex portion 14 of the horizontal piece 11b.
At this time, since the vertical piece 11a has the inclined surface 12 formed on the upper side, even if the lower end of the wall plate 3 may collide with the inclined surface 12 during installation, the vertical piece 11a may be inclined in the oblique direction as indicated by arrows Q and Q. And the wall plate lower end 3b is prevented from being damaged.
[0017]
When the lower side surface of the recess 13 is an inclined surface as shown in the figure, damage to this portion due to collision is similarly prevented.
Further, the rear surface of the wall plate 3 after the installation is linearly supported by the protruding apex portion 12a of the inclined surface 12, and the lower end surface is linearly supported by the convex portion 14, so that there is no permeation of rainwater due to the capillary phenomenon and the water enters temporarily. Even if there is a case, it is discharged from the through hole 16 of the horizontal piece 11b, so that drainage is good. It should be noted that the surface of the horizontal piece 11b is formed as an inclined surface 15 which is inclined downward, and the trough 15a is formed, so that the dischargeability from the through hole 16 is improved.
[0018]

In the receiving member 11 of the outer wall material according to the third embodiment, the support piece 18 contacts the base surface 2 with a large area against the rotational moment due to the load on the wall plate around the fastening portion of the fixture 17. Therefore, the opposing moment can be increased, and the surface thickness per unit can be reduced, so that the base material is not damaged.
[0021]
Embodiment 4
FIG. 5 is a sectional view of the fourth embodiment, and FIG. 6 is a bottom view of the same.

And a rib-shaped projection 14 is formed along the extending end of the horizontal piece 11b.
Accordingly, rainwater permeates into the wall plate surface side from the waterproof seal portion 3b of the wall plate joint portion 3a, but since the horizontal piece 11b is on the rear side of the wall plate with respect to the seal portion 3b, the infiltrated rainwater is on the horizontal piece 11b. Does not flow into
[0023]
Therefore, it is not necessary to provide a through hole for drainage on the surface of the horizontal piece 11b, and the manufacture becomes easier.
FIG. 7 is a sectional view of the fifth embodiment.
