Abstract
Description
この発明は、住宅などの建物に於いて、布基礎と土台との間に介装して、床下換気用の通気路を形成するのに用いる基礎パッキンに関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foundation packing used for forming an air passage for under-floor ventilation interposed between a fabric foundation and a base in a building such as a house.
従来の基礎パッキンは、通常、長さが20cm程度のブロック体で、これを布基礎と土台との間の適所に介装することによって、布基礎と土台との間に間隙を形成し、この間隙を床下換気用の通気路とするものである。また、パッキン自体に通気孔を形成し、布基礎の全長に亘って敷設する方式の長尺の基礎パッキンも提案されている。(特許文献1参照) The conventional foundation packing is usually a block body having a length of about 20 cm, and a gap is formed between the fabric foundation and the foundation by interposing it in a proper position between the fabric foundation and the foundation. The gap is used as an air passage for underfloor ventilation. In addition, a long foundation packing has been proposed in which a ventilation hole is formed in the packing itself and laid over the entire length of the fabric foundation. (See Patent Document 1)
ところが、前記従来の基礎パッキンでは、例えば、短尺のものの場合には、その設置箇所の特定が重要で、施工時に慎重に設置箇所を定める必要があり、施工不良を招くおそれがある。長尺の基礎パッキンを用いれば、この問題は解消されるが、パッキン自体に通気孔を設けなければならず、パッキンの厚さは、10〜30mm程度と薄いので、これに幅方向に抜ける通気孔を設けるとなると、通気孔が小さくなって、充分な通気量を確保できなくなるという問題がある。 However, in the case of the conventional basic packing, for example, in the case of a short one, it is important to specify the installation location, and it is necessary to carefully determine the installation location at the time of construction, which may lead to construction failure. If a long basic packing is used, this problem can be solved. However, a ventilation hole must be provided in the packing itself, and the thickness of the packing is as thin as about 10 to 30 mm. When the pores are provided, there is a problem that the ventilation hole becomes small and a sufficient ventilation amount cannot be secured.
本発明は、このような点に鑑み、充分な通気性を確保できる長尺の基礎パッキンを提供するにある。 In view of such a point, the present invention is to provide a long foundation packing capable of ensuring sufficient air permeability.
本発明の基礎パッキンの技術的手段は、布基礎と土台との間に、全長に亘って介装される長尺の基礎パッキンに於いて、基礎パッキンには、幅方向に抜ける通気孔が多数形成され、更に、基礎パッキンの平面中央部には、アンカーボルト用の孔が全長に亘って形成され、かつ、この孔の形成位置は、基礎パッキンの長手方向に非対称になっており、更に、基礎パッキンの両端には、連絡用の凸部と凹部とが共に形成され、かつ、凸部と凹部との形成位置は、基礎パッキンの長手方向の向きを逆にしても連結できるようになっていることにある。 The technical means of the foundation packing of the present invention is a long foundation packing interposed between the fabric foundation and the base over the entire length, and the foundation packing has a large number of ventilation holes that pass through in the width direction. Further, a hole for an anchor bolt is formed over the entire length in the center of the plane of the foundation packing, and the formation position of this hole is asymmetric in the longitudinal direction of the foundation packing, Both ends of the base packing are formed with connecting convex portions and concave portions, and the formation positions of the convex portions and the concave portions can be connected even if the longitudinal direction of the basic packing is reversed. There is to be.
また、通気孔の断面形状は、やや縦長の4角形で、互に隣接させて、基礎パッキンの全長に亘って多数連続状に形成するようにしてもよい。更に、アンカーボルト用の孔の方に突出するように小片を設け、この小片に釘止め用の孔を形成してもよい。また、通気孔の端の口壁にテーパを付してもよい。 Moreover, the cross-sectional shape of the vent holes may be a slightly vertically long quadrilateral that is adjacent to each other and formed in a continuous manner over the entire length of the foundation packing. Furthermore, a small piece may be provided so as to protrude toward the hole for the anchor bolt, and a hole for fastening a nail may be formed in this small piece. Further, the mouth wall at the end of the vent hole may be tapered.
本発明の基礎パッキンは、布基礎の全長に亘って敷き並べるので、パッキン設置位置に対する注意が不要で、施工ミスを防止できる他、パッキンには通気孔があるので、床下換気を図ることができる。更に、アンカーボルト用の孔が長手方向に非対称に設けられているので、孔とボルトの位置が上手く合わない場合には、パッキンの長手方向の向きを逆にすれば、合うようになり、施工上、極めて有益である。なお、基礎パッキンの両端には、連結用の凸部と凹部とが形成され、向きを逆にした場合でも連結できるようになっている。 Since the foundation packing of the present invention is laid out over the entire length of the fabric foundation, it is not necessary to pay attention to the packing installation position, and it is possible to prevent construction mistakes. . Furthermore, since the holes for anchor bolts are provided asymmetrically in the longitudinal direction, if the positions of the holes and bolts do not match well, they can be matched by reversing the longitudinal direction of the packing. It is extremely useful. In addition, the convex part and recessed part for a connection are formed in the both ends of the foundation packing, and it can connect even if it reverses direction.
本発明の基礎パッキンを実施するための最良の形態を、図面の実施例に基づいて説明する。基礎パッキン1は、通常、厚さが10〜30mmである。また、幅は70〜200mmで、土台の幅に合わせて定められる。長さは、500〜2000mm程度と長尺で、これを直列に連結し、また、場合によっては、適当に切断して使用される。材質は、剛性ないし多少弾性を持ったもの、例えば、合成樹脂、ゴム、金属、セラミックなどが使用可能である。実施例では、ポリプロピレン樹脂を用いている。 The best mode for carrying out the basic packing of the present invention will be described based on the embodiments of the drawings. The base packing 1 usually has a thickness of 10 to 30 mm. The width is 70 to 200 mm and is determined according to the width of the base. The length is as long as about 500 to 2000 mm, which are connected in series, and in some cases, the length is appropriately cut. The material may be rigid or somewhat elastic, for example, synthetic resin, rubber, metal, ceramic or the like. In the embodiment, polypropylene resin is used.
基礎パッキン1には、幅方向に抜ける多数の通気孔2が形成されている。基礎パッキン1は、使用時に厚さ方向に圧縮荷重を受けるので、通気孔2の形成に際しては、必要とする圧縮強度が確保されるように設計する。図示例では、通気孔2の断面形状は、やや縦長の4角形であり、互に隣接させて、全長に亘って多数連続状に形成されている。また、図に示されるように、通気孔2の端の口壁にはテーパが付いている。更に、各通気孔2は、上下いずれかの壁面に開放部3が形成されている。即ち、各孔は、左右の側壁4と、上下いずれか一方の壁5との3方囲繞形態であり、残りの一方は開放部3で、ここでは自由に通気が可能である。これにより、通気面積が増加し、換気性能を高めることができ、かつ、上下に接する布基礎や土台の接触面を乾燥させることができる。またこの開放部3は、パッキンの長手方向及び幅方向に沿って、上下交互に形成されている。これにより、開放部の形成に伴う、パッキンの撓み強度の低下を抑制できる。 The base packing 1 is formed with a large number of ventilation holes 2 that pass through in the width direction. Since the foundation packing 1 receives a compressive load in the thickness direction during use, the base packing 1 is designed so as to ensure the necessary compressive strength when forming the air holes 2. In the illustrated example, the cross-sectional shape of the vent holes 2 is a slightly vertically long quadrangular shape, and a plurality of the vent holes 2 are continuously formed over the entire length so as to be adjacent to each other. Further, as shown in the figure, the mouth wall at the end of the vent hole 2 is tapered. Furthermore, each vent hole 2 has an open portion 3 formed on one of the upper and lower wall surfaces. In other words, each hole has a three-sided form of left and right side walls 4 and either one of the upper and lower walls 5, and the other one is an open portion 3, which can be freely ventilated here. Thereby, a ventilation area increases, ventilation performance can be improved, and the contact surface of the fabric foundation and foundation which touches up and down can be dried. The open portions 3 are alternately formed in the vertical direction along the longitudinal direction and the width direction of the packing. Thereby, the fall of the bending strength of packing accompanying formation of an opening part can be suppressed.
基礎パッキン1には、その平面中央部にアンカーボルトが通る為の4角形の孔6が、全長に亘って連続的に形成されている。また、図3に示されるように、基礎パッキン1の両端には、連結用の凸部7及び凹部8が形成されていて、パッキンを直列状に繋げて使用できるようになっている。更に、図3に示されるように、アンカーボルト用の孔6の形成位置が、パッキンの長手方向に非対称になっているので、アンカーボルトが孔6に上手く嵌り合わない場合には、パッキンの長手方向の向きを逆にして使用するようにする。この為、図示のように、パッキン1の両方の端には、それぞれ凸部7と凹部8とが共に形成され、かつ、その形成位置は、パッキンの長手方向の向きを逆にしても連結できるようになっている。また、図3の9は釘止め用の孔である。この孔9は、図示のように、アンカーボルト用の孔6の方に突出するように設けた小片に形成されている。なお、パッキン1の表裏の表面には、滑り止めの為のシボ加工を施すことも可能である。 In the base packing 1, a quadrangular hole 6 through which the anchor bolt passes is formed continuously over the entire length in the center of the plane. Moreover, as shown in FIG. 3, the convex part 7 for connection and the recessed part 8 are formed in the both ends of the base packing 1, and it can be used by connecting packing now in series. Furthermore, as shown in FIG. 3, the formation position of the hole 6 for the anchor bolt is asymmetric in the longitudinal direction of the packing, so if the anchor bolt does not fit well into the hole 6, the longitudinal direction of the packing Use in the opposite direction. For this reason, as shown in the drawing, both ends of the packing 1 are formed with a convex portion 7 and a concave portion 8 respectively, and the formation positions can be connected even if the longitudinal direction of the packing is reversed. It is like that. Further, 9 in FIG. 3 is a nail hole. The hole 9 is formed in a small piece provided so as to protrude toward the anchor bolt hole 6 as shown in the figure. In addition, the front and back surfaces of the packing 1 can be subjected to a graining process for preventing slipping.
以上のような基礎パッキン1は、布基礎20の上に、直列状に敷き並べて使用する。また、布基礎20の長さに応じ、パッキン1は適当に切断して使用する。基礎パッキン1の裏面の両縁辺には、図5に示されるように、傾斜状の切欠10が形成されていて、布基礎20の形成時のコンクリート打設によって生ずる、上端隅角部のバリ21を吸収可能である。従って、バリ21が存在していても、パッキン1の敷き並べには支障が出ない。30は土台である。 The foundation packing 1 as described above is laid and used in series on the cloth foundation 20. Further, the packing 1 is appropriately cut and used in accordance with the length of the fabric foundation 20. As shown in FIG. 5, inclined notches 10 are formed on both edges of the back surface of the foundation packing 1, and burrs 21 at the upper corners caused by concrete placement when the fabric foundation 20 is formed. Can be absorbed. Therefore, even if the burr 21 is present, there is no problem in arranging the packings 1. 30 is a foundation.
このように、布基礎20と土台30との間に介装されたパッキン1には多数の通気孔2が形成されているので、この孔を通って空気の流通が可能であり、床下換気を図ることができる。更に、通気孔2の上面または下面のいずれかが開放形状になっているので、通気性に富み、かつ、布基礎20や土台30の接触面を乾燥させることができる。更に、パッキン1の表裏面に開放部の形成に伴う切欠が存在するので、これが布基礎や土台と接触した際の滑り止めとなり、布基礎と土台との間に介装したパッキンは、長期に亘り安定よく保持される。 As described above, since a large number of air holes 2 are formed in the packing 1 interposed between the fabric foundation 20 and the base 30, air can be circulated through the holes, and underfloor ventilation can be performed. Can be planned. Furthermore, since either the upper surface or the lower surface of the vent hole 2 has an open shape, it is rich in air permeability and the contact surfaces of the fabric foundation 20 and the base 30 can be dried. In addition, since there are notches on the front and back surfaces of the packing 1 due to the formation of the open portion, this prevents slipping when it comes into contact with the fabric foundation or foundation, and the packing interposed between the fabric foundation and the foundation is long-lasting. It is held stably over a long period.
本発明は、前記の実施例に限定されるものではなく、特許請求の範囲の記載の範囲内で自由に変形実施可能である。特に、パッキン1の厚さ、幅、長さ、及び材質などは自由である。更に、通気孔2の開放部3の形状や形成形態なども自由である。 The present invention is not limited to the above-described embodiments, and can be freely modified within the scope of the claims. In particular, the thickness, width, length, material, and the like of the packing 1 are free. Furthermore, the shape and form of the opening 3 of the vent hole 2 are also free.
