Description

【0001】
【発明の属する技術分野】
本発明は、住宅の基礎の外側に取り付ける断熱材と、その構成に関する。
【0002】
【従来の技術】
外断熱構造は、建物構造体外部に断熱材を連続して施工できることから、断熱ライン(気密ライン)に欠損が生じることがない。
このことから、外断熱構造は建物構造体内部の熱分布にムラが生じない気密性の高い断熱構造であるというのが特徴である。
以上の特徴より、冬場の暖房効率を大幅に向上することができるため、近年、特に寒冷地においては、該外断熱構造が多く採用されている。
【0003】
該外断熱構造の一つとして建物基礎の外周部(建物外側)を断熱材で覆う外断熱基礎構造がある。一般的には、基礎の外周に断熱材を貼設し、該断熱材の上にモルタルを塗りこむものが一般的である。該断熱材の外周には、モルタル刷毛引などにより、断熱材の耐候性の向上が図られている。
また、前記水切りは、雨水の断熱材への浸入による断熱材内のカビの発生や腐食を防いでいる。
【0004】
【発明が解決しようとする課題】
上記水切りは、その上面に雨水や雪等を溜めないために傾斜を有することが望ましい。
そこで、水切りに傾斜させて取り付ける際には、水切りの下に存在する断熱材は以下のいずれかの構成であることが必要となる。
一つは断熱材の上面を斜めに形成すること、または、断熱材の上面を基礎の上面よりも低く位置させることである。
【0005】
まず、断熱材の上面を斜めに形成する際には、断熱材の製作時に、斜めにカットする加工の必要があることから、製作に手間がかかるのである。
また、断熱材の上面を基礎の上面よりも低く位置させた際には、基礎の上部に断熱材が存在しなくなるため、断熱効果が損なわれてしまうのである。特に、寒冷地においては、断熱材の存在しない基礎外周面を構成してしまうことにより、断熱効果に大きな影響を与えるため、基礎外周面は完全に断熱されておくことが必要なのである。
【0006】
即ち、本発明の課題とするところは、断熱効果を損なうことなく、水切りに傾斜を構成することにより生じる弊害(断熱材の上面を斜めに加工すること)を克服し、傾斜を有する水切りの設置を可能にすることである。
【0007】
【課題を解決するための手段】
本発明の解決しようとする課題は以上のごとくであり、次に該課題を解決する為の手段を説明する。
請求項1においては、建物基礎3の外周を断熱する構成の外断熱基礎において、該基礎3の外周側面に基礎断熱パネル5を接着剤によって貼設し、該基礎断熱パネル5の上面は、基礎3の上面より低い位置とし、一定長さを残した段落ち状の構成とし、該段落ちさせることによって生じた、基礎断熱パネル5の存在しない空間を断熱する部材として、基礎上断熱材10を設け、該基礎上断熱材10は、基礎3の上の基礎断熱パネル5の存在しない一定長さの側面と、更に基礎3の上面を覆い断熱する部材としたものである。
【0008】
請求項2においては、請求項1記載の外断熱基礎において、前記基礎上断熱材10は、該基礎3の一定長さの外側上部側面に当接する面と、基礎3の上面に当接する面とにより構成され、断面視略逆L字状としたものである。
【0009】
請求項3においては、請求項2記載の外断熱基礎において、前記基礎上断熱材10の、基礎3の上面に当接する面の上側表面に、外壁4の底面と基礎上断熱材10の間に通気可能とする空間を形成するスペーサー42を配置したものである。
【0010】
【発明の実施の形態】
次に、本発明の実施の形態を、図面に基づいて説明する。
図1は本発明の実施例の全体構成の斜視図、図2は同じく側面断面図、図3は外壁の設置部の詳細図、図4は出隅における基礎上断熱材の取付状態を表す斜視図、図5は入隅における基礎上断熱材の取付状態を表す斜視図である。
【0011】
まず、本発明を適用した実施例の概要について説明する。
図1及び図2に示すごとく、地盤1に配した捨コンクリート2の上に、基礎3を設置し、該基礎3の上に外壁4が配される。そして、該基礎3の外側面(地盤1側)には、基礎断熱パネル5が接着剤によって貼設されている。該基礎断熱パネル5は、その外側面を外装板15で構成し耐候性及び美観を向上させている。
また、該基礎断熱パネル5は基礎3の側面に固設され外側に突設した水切り受金具6によって、設置作業において仮固定(位置決めとなる)され、該水切り受金具6の上には水切り8を嵌合保持する水切りジョイナー7が設置されている。
また、前記基礎断熱パネル5の上部には、水切りジョイナー7及び水切り8が構成される必要があるため、基礎断熱パネル5の上面は基礎3の上面より段落ちさせる構成(低い位置)としている。このように、段落ちさせることによって生じた基礎断熱パネル5の存在しない空間を断熱する部材として、基礎断熱パネル5の上端から外壁4の下部にかけて、基礎上断熱材10が基礎3の側面に添わせるようにして貼設されている。
【0012】
次に、基礎上断熱材10について説明する。
図1及び図2に示すごとく、該基礎上断熱材10は、基礎3の外側表面のうち、基礎断熱パネル5が存在しない表面を覆うものである。該基礎上断熱材10の断面形状は、基礎3の段付部31の表面に沿わせる形状、即ち、取り付け時において、略逆「L」字状(本実施例では、基礎3の段付部31を段落ちさせているため、階段形状とした)としている。さらに、断熱効果を高めるために、外側面(基礎3と反対側面)を二重構成としている。
また、該基礎上断熱材10の裏側(基礎3に当接する側)には接着テープがあらかじめ貼設されており、施工時においては該接着テープの離型紙を剥がすだけで、基礎3に貼設することを可能にしている。
【0013】
該基礎上断熱材10は、前記基礎断熱パネル5とともに、基礎3の外周に連続的に貼設することによって、基礎3の外周全体を覆うものである。そこで、該基礎上断熱材10の幅方向の長さは、数種の幅のバリエーションを有し、さまざまな基礎3の長さに対応できるようにしている。
【0014】
また、図1及び図3に示すごとく、外壁4の設置のための基礎3に適宜配されたアンカーボルト49・49・・・の存在する位置においては、外壁4の固定部下面に設けた軸プレート44・44・・・を基礎3の上面に当接させることにより、外壁4の設置を確実にする(弾性部材である基礎上断熱材10を介装しないということ)ため、該軸プレート44・44・・・が存在する基礎上断熱材10の上面の一部には切欠き45(図1に示す)を構成している。
【0015】
尚、該基礎上断熱材10の素材としては、ポリエチレン等の合成樹脂発泡体を用い、一体成型とするものである。また、施工現場での基礎3に対する誤差が生じた際に対応するため、カッター等で簡単に切断可能とすることが望ましい。
【0016】
さらに、該基礎上断熱材10は、壁体内通気を行う外壁に対応する構成とすることもできる。ここで、壁体内通気とは、内壁断熱材に湿気が滞留しないようにしてカビや雑菌の発生を防ぐものである。
図3に示すごとく、外壁4の下部には軸プレート44・44・・・を構成しているため、外壁4の下面のその他の部分は、基礎3との間に空間が保たれ、通気孔41・41・・・も塞がれることはない。
【0017】
しかし、基礎3と外壁4の間に基礎上断熱材10を介装した場合には、基礎上断熱材10の厚さが設計通りであっても、基礎の上面の高低の誤差により基礎上断熱材10の上面が通気孔41・41・・・に当接してしまう場合が生じ得る。また、長期間の外気温の変化・吸湿等により、基礎上断熱材10の膨張・伸縮・変形が生じた際にも同様のことが生じ得るのである。
【0018】
そこで、上記の不具合を想定し、通気孔壁体内通気のための通気孔41・41・・・の下部において、外壁4の底面と基礎上断熱材10の間に空気が通る空間(隙間)を常に確保することができるように、通気孔41・41・・・の両端となる位置にスペーサー42・42を、基礎上断熱材10の上に形成した。
【0019】
また、該スペーサー42・42は、上述のごとく、基礎上断熱材10の一部として、一体成型品としてもよいが、基礎上断熱材10の他の部材よりも硬質の素材で構成すれば、さらに耐候性が向上し、より確実に空気の通り道を確保することができる。
【0020】
以上のごとく構成した基礎上断熱材10は、基礎3の形状(出隅や入隅等)に合うように、予め工場で製作される。これは、施工現場での加工作業を極力少なくするため、及び基礎上断熱材10の取り付け精度を上げるためでもある。
とくに、外壁4の通気孔41・41・・・の外気通気を妨げないため(壁体内通気に対応する場合)、また、外壁4の設置のための基礎3に適宜配されたアンカーボルト49・49・・・の配置に対応するためには、予め設計長さ通りに加工された基礎上断熱材10が搬入される必要がある。
また、出隅・入隅では、その角部に隙間が生じないことが必要となる。
【0021】
そこで、図1に示すごとく、凹凸部のない一般部には直線形状の基礎上断熱材10を貼設する。また、図4及び図5に示すごとく、出隅においては、出隅基礎上断熱材78を貼設し、入隅においては、入隅基礎上断熱材79を貼設する。
以上の基礎上断熱材10、出隅基礎上断熱材78及び入隅基礎上断熱材79を、連接(隙間を生じないように)することにより、基礎3の形状(通気孔41及びアンカーボルト49)に対応できる。具体的には、まず、出隅基礎上断熱材78を出隅に取り付け、該出隅基礎上断熱材78を基準として連接すること等である。こうして、施工作業が簡単に行えるのである。また、出隅・入隅においても、その角部に隙間が生じることがないのである。
【0022】
【発明の効果】
本発明は以上のごとく構成したので、次のような効果を奏するのである。
請求項1に記載のごとく、建物基礎3の外周を断熱する構成の外断熱基礎において、該基礎3の外周側面に基礎断熱パネル5を接着剤によって貼設し、該基礎断熱パネル5の上面は、基礎3の上面より低い位置とし、一定長さを残した段落ち状の構成とし、該段落ちさせることによって生じた、基礎断熱パネル5の存在しない空間を断熱する部材として、基礎上断熱材10を設け、該基礎上断熱材10は、基礎3の上の基礎断熱パネル5の存在しない一定長さの側面と、更に基礎3の上面を覆い断熱する部材としたので、基礎断熱パネル5の上面の上一定長さを残して基礎3の上面に対して低く構成することができて水切りを配置できるとともに、その部分は基礎上断熱材10によって基礎3の上面を断熱できる。
即ち、水切り8に傾斜を構成させることにより生じる弊害(断熱材の上面を斜めに加工すること)を克服し、傾斜を有する水切り8の設置を可能にするのである。
そして、基礎上面も基礎上断熱材で覆うので、建物基礎の外周を殆ど断熱材で覆うことができるのである。
【0023】
請求項2に記載のごとく、前記基礎上断熱材10は、該基礎3の一定長さの外側上部側面に当接する面と、基礎3の上面に当接する面とにより構成され、断面視略逆L字状としたので、基礎3の形状に沿って貼設することができ、基礎上断熱材10と基礎3の間に空間を形成しないことから、高い断熱効果を得られる。
また、面で構成するため該基礎上断熱材10を取り付けた後においても、基礎3の外形が維持できることから、水切り8等の取り付けの際に邪魔になることもなく、また、構成が簡単で容易に製作することができるのであるのである。
【0024】
請求項3に記載のごとく、前記基礎上断熱材10の、基礎3の上面に当接する面の上側表面に、外壁4の底面と基礎上断熱材10の間に通気可能とする空間を形成するスペーサー42を配置したので、通気孔41・41・・・が基礎上断熱材10の上面で確実に確保できて、空気の通り道を確保することができることから、壁体内通気を行える外壁に対応することができるのである。

BACKGROUND OF THE INVENTION
The present invention relates to a heat insulating material attached to the outside of a foundation of a house, and a configuration thereof.
[0002]
[Prior art]
Since the heat insulating material can be continuously applied to the outside of the building structure, the outer heat insulating structure does not cause a defect in the heat insulating line (airtight line).
For this reason, the outer heat insulating structure is characterized by a highly airtight heat insulating structure that does not cause unevenness in the heat distribution inside the building structure.
Due to the above characteristics, the heating efficiency in winter can be greatly improved, and in recent years, especially in cold regions, the outer heat insulating structure is often used.
[0003]
As one of the outer heat insulating structures, there is an outer heat insulating basic structure that covers an outer peripheral portion (outside of a building) of a building foundation with a heat insulating material. In general, a heat insulating material is attached to the outer periphery of the foundation, and mortar is applied on the heat insulating material. On the outer periphery of the heat insulating material, the weather resistance of the heat insulating material is improved by mortar brushing or the like.
Moreover, the draining prevents the generation of mold and corrosion in the heat insulating material due to the penetration of rainwater into the heat insulating material.
[0004]
[Problems to be solved by the invention]
It is desirable that the drainer has an inclination so as not to collect rainwater or snow on its upper surface.
Therefore, when attaching to the drainer by inclining, it is necessary that the heat insulating material existing under the drainer has one of the following configurations.
One is to form the upper surface of the heat insulating material obliquely, or to position the upper surface of the heat insulating material lower than the upper surface of the foundation.
[0005]
First, when the upper surface of the heat insulating material is formed obliquely, since it is necessary to cut obliquely when the heat insulating material is manufactured, it takes time and effort.
In addition, when the upper surface of the heat insulating material is positioned lower than the upper surface of the foundation, the heat insulating material does not exist at the upper portion of the foundation, so that the heat insulating effect is impaired. In particular, in a cold district, the foundation outer peripheral surface without heat insulating material is configured to greatly affect the heat insulating effect, and therefore the foundation outer peripheral surface needs to be completely insulated.
[0006]
That is, the subject of the present invention is to overcome the adverse effect (processing the upper surface of the heat insulating material obliquely) caused by constructing the slope in the drainer without impairing the heat insulation effect, and to install the drainer having the slope. Is to make it possible.
[0007]
[Means for Solving the Problems]
The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.
In Claim 1, in the external heat insulation foundation of the structure which heat-insulates the outer periphery of the building foundation 3, the foundation heat insulation panel 5 is stuck on the outer peripheral side surface of the foundation 3 with an adhesive agent, and the upper surface of the foundation heat insulation panel 5 is the foundation. As a member that insulates the space where the foundation heat insulation panel 5 does not exist, which is caused by a step-down configuration with a certain length remaining, and is lower than the upper surface of 3, The foundation heat insulating material 10 is a member that covers and insulates the side surface of a certain length where the foundation heat insulation panel 5 on the foundation 3 does not exist and the upper surface of the foundation 3 .
[0008]
According to claim 2, in the outer heat insulating foundation according to claim 1, the upper heat insulating material 10 includes a surface that contacts the upper upper side surface of the fixed length of the base 3, and a surface that contacts the upper surface of the base 3. The cross-sectional view is substantially inverted L shape .
[0009]
According to claim 3, in the outer heat insulating foundation according to claim 2, between the bottom surface of the outer wall 4 and the foundation heat insulating material 10 on the upper surface of the surface of the heat insulating material 10 on the foundation that contacts the upper surface of the foundation 3. A spacer 42 that forms a space allowing ventilation is arranged .
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of the overall configuration of an embodiment of the present invention, FIG. 2 is a side sectional view, FIG. 3 is a detailed view of an installation portion of an outer wall, and FIG. FIG. 5 and FIG. 5 are perspective views showing the mounting state of the heat insulating material on the foundation at the corner.
[0011]
First, the outline | summary of the Example to which this invention is applied is demonstrated.
As shown in FIG. 1 and FIG. 2, the foundation 3 is installed on the discarded concrete 2 arranged on the ground 1, and the outer wall 4 is arranged on the foundation 3. And the foundation heat insulation panel 5 is affixed on the outer surface (ground 1 side) of this foundation 3 with the adhesive agent. The basic heat insulating panel 5 has an outer surface composed of an exterior plate 15 to improve weather resistance and aesthetic appearance.
In addition, the foundation heat insulating panel 5 is temporarily fixed (positioned) in the installation operation by a draining bracket 6 fixed on the side surface of the foundation 3 and protruding outward, and the drainage 8 is placed on the draining bracket 6. A drainer joiner 7 that fits and holds is installed.
Moreover, since it is necessary to comprise the draining joiner 7 and the draining 8 in the upper part of the said foundation heat insulation panel 5, the upper surface of the foundation heat insulation panel 5 is set as the structure (low position) which steps down from the upper surface of the foundation 3. FIG. As described above, as a member for insulating the space where the base heat insulation panel 5 does not exist generated by the stepping down, the base heat insulating material 10 is attached to the side surface of the base 3 from the upper end of the base heat insulation panel 5 to the lower part of the outer wall 4. It is pasted to make it.
[0012]
Next, the foundation heat insulating material 10 will be described.
As shown in FIGS. 1 and 2, the heat insulating material 10 on the foundation covers a surface of the outer surface of the foundation 3 where the foundation heat insulating panel 5 does not exist. The cross-sectional shape of the heat insulating material 10 on the foundation is a shape along the surface of the stepped portion 31 of the foundation 3, that is, a substantially inverted “L” shape at the time of mounting (in this embodiment, the stepped portion of the foundation 3 Since step 31 is dropped, a staircase shape is used. Furthermore, in order to improve the heat insulation effect, the outer side surface (side opposite to the foundation 3) has a double structure.
In addition, an adhesive tape is pasted in advance on the back side (the side in contact with the foundation 3) of the thermal insulation material 10 on the foundation. At the time of construction, the adhesive tape is pasted on the foundation 3 simply by removing the release paper. It is possible to do.
[0013]
The base heat insulating material 10 covers the entire outer periphery of the foundation 3 by being continuously pasted on the outer periphery of the foundation 3 together with the basic heat insulating panel 5. Therefore, the length in the width direction of the heat insulating material 10 on the foundation has variations of several kinds of widths so that various lengths of the foundation 3 can be accommodated.
[0014]
Further, as shown in FIGS. 1 and 3, the shaft provided on the lower surface of the fixed portion of the outer wall 4 at a position where anchor bolts 49, 49... Appropriately disposed on the foundation 3 for installing the outer wall 4 exist. In order to ensure the installation of the outer wall 4 by bringing the plates 44, 44... Into contact with the upper surface of the foundation 3 (that is, the foundation-side heat insulating material 10 which is an elastic member is not interposed), the shaft plate 44 A notch 45 (shown in FIG. 1) is formed in a part of the upper surface of the base heat insulating material 10 where 44.
[0015]
In addition, as a raw material of this heat insulating material 10 on a foundation, synthetic resin foams, such as polyethylene, are used, and it is set as integral molding. Moreover, in order to cope with the case where an error occurs with respect to the foundation 3 at the construction site, it is desirable that the cutter can be easily cut.
[0016]
Furthermore, the base heat insulating material 10 may be configured to correspond to an outer wall that ventilates the wall. Here, the ventilation in the wall is to prevent generation of mold and bacteria by preventing moisture from staying in the inner wall heat insulating material.
As shown in FIG. 3, since shaft plates 44, 44,... Are formed in the lower part of the outer wall 4, a space is maintained between the other portions of the lower surface of the outer wall 4 and the foundation 3, and ventilation holes are provided. 41, 41... Will not be blocked.
[0017]
However, when the foundation heat insulating material 10 is interposed between the foundation 3 and the outer wall 4, even if the thickness of the foundation heat insulating material 10 is as designed, the heat insulation on the foundation is caused by an error in the height of the upper surface of the foundation. There may be a case where the upper surface of the material 10 comes into contact with the vent holes 41. In addition, the same can occur when the thermal insulation material 10 on the foundation expands, expands, contracts, or deforms due to a long-term change in the outside air temperature, moisture absorption, or the like.
[0018]
Therefore, assuming the above problems, a space (gap) through which air passes between the bottom surface of the outer wall 4 and the heat insulating material 10 on the foundation is provided below the ventilation holes 41, 41,. Spacers 42 and 42 are formed on the base heat insulating material 10 at positions that are both ends of the air holes 41, 41,.
[0019]
In addition, as described above, the spacers 42 and 42 may be integrally molded as a part of the foundation heat insulating material 10, but if they are made of a material harder than other members of the foundation heat insulating material 10, Furthermore, the weather resistance is improved, and the passage of air can be secured more reliably.
[0020]
The heat insulating material 10 on the foundation configured as described above is manufactured in advance in a factory so as to fit the shape of the foundation 3 (extruding corner, entering corner, etc.). This is also for the purpose of minimizing the processing work on the construction site and for increasing the mounting accuracy of the heat insulating material 10 on the foundation.
In particular, in order not to disturb the outside air ventilation of the ventilation holes 41, 41... In the outer wall 4 (when corresponding to the ventilation in the wall), the anchor bolts 49. In order to correspond to the arrangement of 49..., It is necessary to carry in the heat insulating material 10 on the foundation that has been processed according to the design length in advance.
Further, it is necessary that no gap is generated at the corners at the protruding corner and the entering corner.
[0021]
Therefore, as shown in FIG. 1, a linear base heat insulating material 10 is attached to a general part having no uneven part. Moreover, as shown in FIG.4 and FIG.5, the protrusion corner top heat insulating material 78 is affixed in an exit corner, and the entrance corner foundation heat insulating material 79 is affixed in an entrance corner.
The shape of the foundation 3 (the air holes 41 and the anchor bolts 49) is obtained by connecting the above-mentioned foundation upper heat insulating material 10, the protruding corner base upper heat insulating material 78, and the entry corner basic heat insulating material 79 (so as not to generate a gap). ). Specifically, first, the heat insulating material 78 on the protruding corner foundation is attached to the protruding corner, and the heat insulating material 78 on the protruding corner foundation is connected as a reference. Thus, the construction work can be easily performed. In addition, there is no gap at the corners at the corners at the exit and entry.
[0022]
【The invention's effect】
Since the present invention is configured as described above, the following effects can be obtained.
As described in claim 1, in the outer heat insulating foundation configured to insulate the outer periphery of the building foundation 3, the basic heat insulating panel 5 is attached to the outer peripheral side surface of the foundation 3 with an adhesive, and the upper surface of the basic heat insulating panel 5 is As a member that insulates the space where the base heat insulation panel 5 does not exist, which is formed in a stepped configuration with a certain length left below the upper surface of the foundation 3, and is caused by the stepping, 10 is provided as a member that covers and insulates the side surface of the fixed length on which the foundation heat insulation panel 5 does not exist on the foundation 3 and the upper surface of the foundation 3 . The upper surface of the foundation 3 can be configured to be lower than the upper surface of the foundation 3 by leaving a certain length on the upper surface, and a drainer can be arranged.
That is, the adverse effect (processing the upper surface of the heat insulating material diagonally) caused by configuring the drainage 8 to be inclined is overcome, and the installation of the drainer 8 having an inclination is made possible.
And since the upper surface of the foundation is also covered with the heat insulating material on the foundation, the outer periphery of the building foundation can be almost covered with the heat insulating material.
[0023]
As described in claim 2, the thermal insulation 10 on the foundation is constituted by a surface that abuts on the outer upper side surface of the fixed length of the foundation 3 and a surface that abuts on the upper surface of the foundation 3. Since it was L-shaped, it can be affixed along the shape of the foundation 3, and since a space is not formed between the heat insulating material 10 on the foundation and the foundation 3, a high heat insulation effect can be obtained.
Further, since the outer shape of the foundation 3 can be maintained even after the heat insulating material 10 on the foundation is attached because it is constituted by a surface, it is not obstructive when attaching the drainer 8 or the like, and the structure is simple. It can be easily manufactured.
[0024]
As described in claim 3, a space that allows ventilation is formed between the bottom surface of the outer wall 4 and the base heat insulating material 10 on the upper surface of the surface of the base heat insulating material 10 that contacts the top surface of the base 3. Since the spacer 42 is disposed , the vent holes 41, 41,... Can be reliably secured on the upper surface of the base heat insulating material 10, and air passages can be secured. It can be done.
