Description

本発明は、基礎と外壁パネルの間に基礎水切材が設けられる基礎通気防水構造に関する。 The present invention relates to a foundation ventilation waterproof structure in which a foundation drainer is provided between a foundation and an outer wall panel.

従来より、基礎に換気口を形成して、床下空間に空気を流通させて床下空間の湿気を外部に排出する技術が知られている。しかし、基礎に換気口を形成する場合には、基礎の強度低下を補うために換気口の周縁に特別な配筋が必要になり、又、コンクリート打設時に特別な型枠が必要になるなど施工が煩雑になる問題があった。 2. Description of the Related Art Conventionally, a technique is known in which a ventilation port is formed in a foundation, air is circulated through the underfloor space, and moisture in the underfloor space is discharged to the outside. However, when forming a ventilation opening in the foundation, special reinforcement is required around the ventilation opening to compensate for the strength reduction of the foundation, and a special formwork is required when placing concrete. There was a problem that construction was complicated.

そこで近年では、基礎の天端面と外壁パネルの下端面との間に隙間を形成し、この隙間を床下換気経路として利用して床下空間の換気を図ることが行われている。また、外壁パネルの屋内側には、防湿などの目的で壁体内通気経路が設けられており、この壁体内通気経路は、基礎の天端面と外壁パネルの下端面との間から外壁パネルの屋内側に鉛直方向に設けられている。このような構造において、基礎の天端面と外壁パネルの下端面との間には、外壁パネルの屋外側を伝って流れる雨水や外気に含まれる雨水が、基礎の天端面と外壁パネルの下端面との間から屋内に浸入することを抑制するために基礎水切材が設けられている。 Therefore, in recent years, a gap is formed between the top end surface of the foundation and the lower end surface of the outer wall panel, and this space is used as an underfloor ventilation path to ventilate the underfloor space. In addition, a wall ventilation path is provided on the indoor side of the outer wall panel for the purpose of moisture prevention, and the wall ventilation path is provided between the top end surface of the foundation and the lower end surface of the outer wall panel. It is provided inside in the vertical direction. In such a structure, the rainwater flowing in the outdoor side of the outer wall panel or the rainwater contained in the outside air flows between the top end surface of the foundation and the lower end surface of the outer wall panel. In order to suppress intrusion into the room from between, a basic drainage material is provided.

例えば特許文献１の基礎水切材は、その下端に通風用開口部が設けられて床下換気口に連通しているとともに、外壁パネルの下端面と基礎水切材との間隙が壁体内通気経路と連通している。外壁パネルの下端面と基礎水切材との間隙には立体網状材が配置されている。また、特許文献２の基礎水切材は、基礎水切材の下端に設けられた外気取入口が床下の通気路と壁体内の通気路とに連通している。さらに、特許文献３の床下換気構造は、基礎水切材の下端に設けられた換気口が床下換気経路に連通しており、基礎天端面の屋外端に基礎水切材の下端に装着されたシール部材のリップ部が密着する構成が記載されている。 For example, the basic drainage material of Patent Document 1 is provided with a ventilation opening at the lower end thereof and communicates with the underfloor ventilation port, and the gap between the lower end surface of the outer wall panel and the basic drainage material communicates with the ventilation path in the wall. doing. A three-dimensional net-like material is disposed in the gap between the lower end surface of the outer wall panel and the basic drainage material. Further, in the basic drainage material of Patent Document 2, an outside air intake port provided at the lower end of the basic drainage material communicates with an air passage under the floor and an air passage in the wall. Furthermore, in the underfloor ventilation structure of Patent Document 3, a vent provided in the lower end of the foundation drainer communicates with the underfloor ventilation path, and a seal member attached to the lower end of the foundation drainer on the outdoor end of the foundation top end surface. The structure which the lip | rip part adheres is described.

しかし、特許文献１の構成は、外壁パネルの下端面と基礎水切材との間隙が壁体内通気経路の入り口となっており、立体網状材が配置されているだけであるので、外壁パネルの屋外側を伝って流れる雨水等が外壁パネルの下端で回りこんで、壁体内通気経路に侵入する外気とともに壁体内通気経路に侵入する場合に立体網状材のみでは侵入する雨水を捕捉しきれないおそれがある。 However, in the configuration of Patent Document 1, the gap between the lower end surface of the outer wall panel and the basic drainage material serves as the entrance of the ventilation path in the wall, and only the three-dimensional mesh material is disposed. When rainwater, etc. that flows along the outside flows around the lower end of the outer wall panel and enters the wall ventilation path together with the outside air that enters the wall ventilation path, there is a risk that the intruding rainwater may not be captured by the solid mesh material alone. is there.

また、特許文献２の構成は、基礎水切材の屋外側の上端が外壁パネルの屋内側の面に当接しているが、外壁パネルの厚さには多少の精度誤差があるので、外壁パネルの寸法精度の誤差によって基礎水切材の上端が外壁パネルの屋内側に当接しない場合や外壁パネルと基礎水切材とが干渉して設置が基礎水切材の設置が困難となる場合があり、外気中に含まれる雨水が外気とともに壁体内通気経路に浸入するおそれがある。 Moreover, although the structure of patent document 2 has contact | abutted the indoor side surface of the outer wall panel with the outdoor upper end of the foundation drainer, since there is some accuracy error in the thickness of the outer wall panel, Due to dimensional accuracy errors, the upper end of the foundation drainer may not contact the indoor side of the outer wall panel, or the outer wall panel and the foundation drainer may interfere with each other, making it difficult to install the foundation drainer. There is a possibility that rainwater contained in the water enters the wall ventilation path together with the outside air.

そして、特許文献３は、上述のような問題がないように、外壁パネルと基礎水切材の上端との間を湿式のシーリング材及びコーキング材で処理している。しかし、シーリング等の処理を行う場合、シーリングの専門職による施工が必要であり、必要以上の防水性能にコストを掛けることとなり問題がある。 And patent document 3 processes with the wet sealing material and caulking material between the outer wall panel and the upper end of a foundation drainer so that there may be no above-mentioned problem. However, when processing such as sealing, construction by a sealing specialist is necessary, and there is a problem that it costs more than necessary waterproof performance.

そこで本発明は、必要十分な防水性能をシーリング施工なしに実現することができる基礎通気防水構造を提供することを目的とする。 Then, an object of this invention is to provide the basic ventilation waterproof structure which can implement | achieve required and sufficient waterproof performance, without sealing construction.

The basic ventilation waterproof structure of the present invention has a wall frame standing upright with an underfloor ventilation path between the top end surface of the foundation and the wall frame, and a ventilation path in the wall between the wall frame and the wall frame. An outer wall panel to be formed; a hanging part that is provided at the lower end of the outer wall panel and hangs downward; a mounting bracket that is fixed to the wall frame; and a vent hole at the lower end and a vent hole at the lower end; A basic ventilating and waterproofing structure comprising: a foundation drainer having a rising portion at an inner edge; and a drainage drainer provided on an outdoor side surface of the wall frame from a lower end of the wall frame to a predetermined height. Is disposed on the indoor side with respect to the drooping portion, the upper end of the rising portion is disposed above the lower end of the dripping portion, and the underfloor ventilation path through which the outside air introduced from the vent hole enters the foundation , And a wall body vent path from entering the wall body ventilation layer between inner and outer walls, mesh material to said wall inside the ventilation path is being arranged.

本発明の基礎通気防水構造によると、外壁パネルの下端部に下方に垂下する垂れ部が形成されており、基礎水切材の上端の屋内側端縁に設けられる立ち上がり部が当該垂れ部よりも屋内側に配置されているので、外壁パネルの下端部と基礎水切材の上端部との間には垂れ部及び立ち上がり部の間の間隙が形成されることになる。したがって、立ち上がり部及び垂れ部を接近するように配置することで、雨水が通過する隙間を細くして、雨水等の浸入を抑制することができる。そして、垂れ部が設けられることで、製造時の精度の問題で外壁パネルの厚みなどに変化がある場合でも、垂れ部と立ち上がり部との間隙を一定に保つことができ、外壁パネルの寸法誤差に関係なく一定の防水性を保つことができる。 According to the basic ventilation waterproof structure of the present invention, a drooping portion that hangs downward is formed at the lower end portion of the outer wall panel, and the rising portion provided at the indoor side edge of the upper end of the basic drainage material is more open than the dripping portion. Since it is arrange | positioned inside, the clearance gap between a drooping part and a standing part will be formed between the lower end part of an outer wall panel, and the upper end part of a basic draining material. Therefore, by arranging the rising portion and the drooping portion so as to approach each other, it is possible to narrow the gap through which rainwater passes and to suppress the intrusion of rainwater or the like. By providing the drooping portion, the gap between the drooping portion and the rising portion can be kept constant even when there is a change in the thickness of the outer wall panel due to accuracy problems during manufacturing. Regardless of the water resistance can be maintained.

本発明の基礎通気防水構造によると、垂れ部の下端は屋内方向に突出する下折部を形成するとともに、立ち上がり部の上端は屋外方向に突出する突出部を形成するので、垂れ部と立ち上がり部との間の隙間は下折部及び突出部によってより間隙を小さくすることができるとともに、垂れ部及び立ち上がり部の間で下折部及び突出部の間の空間が複雑な経路となるので、侵入する外気の勢いを緩めて、外気とともに浸入する雨水をこの空間で止めることができる。また、立ち上がり部の上端に突出部が設けられていることで、この突出部が水返しとなって雨水の浸入をより抑制することができる。 According to the basic ventilation waterproof structure of the present invention, the lower end of the drooping portion forms a lower folding portion protruding in the indoor direction, and the upper end of the rising portion forms a protruding portion protruding in the outdoor direction. The gap between the lower folding part and the protruding part can be further reduced by the lower folding part and the protruding part, and the space between the lower folding part and the protruding part becomes a complicated path between the hanging part and the rising part. The momentum of the outside air can be relaxed, and rainwater entering with the outside air can be stopped in this space. Moreover, since the protruding portion is provided at the upper end of the rising portion, the protruding portion serves as a water return and can further suppress the intrusion of rainwater.

本発明の基礎通気防水構造によると、立ち上がり部の上端に形成される突出部が、軟質樹脂により形成されるので、外壁パネルの寸法誤差で、垂れ部と突出部とが干渉する位置に配置された場合でも、突出部が変形して基礎水切材を適切な位置に収めることができる。 According to the basic ventilation waterproof structure of the present invention, since the protruding portion formed at the upper end of the rising portion is formed of a soft resin, it is disposed at a position where the drooping portion and the protruding portion interfere with each other due to a dimensional error of the outer wall panel. Even if it protrudes, a protrusion part deform | transforms and a basic drainage material can be stored in an appropriate position.

本発明の基礎通気防水構造によると、突出部は先端に向かって先細っており、垂れ部の屋内側の面に接触しているので、立ち上がり部と垂れ部との間の間隙が閉じられることとなり、外壁パネルの下端と基礎水切材の上端の間からの雨水の浸入をより抑制することができる。そして、突出部は軟質樹脂で先端が先細り形状であるので、外壁パネルの寸法誤差で垂れ部の位置が多少設計位置からずれている場合でも、突出部が容易に変形して垂れ部に当接できるので、基礎水切材を適切な位置に収めることができる。 According to the basic ventilation waterproof structure of the present invention, the projecting portion is tapered toward the tip, and is in contact with the indoor side surface of the hanging portion, so that the gap between the rising portion and the hanging portion is closed. Thus, intrusion of rainwater from between the lower end of the outer wall panel and the upper end of the foundation drainer can be further suppressed. And since the protruding part is a soft resin and the tip is tapered, even if the position of the hanging part is slightly deviated from the design position due to the dimensional error of the outer wall panel, the protruding part is easily deformed and comes into contact with the hanging part Since it is possible, the basic drainage material can be stored in an appropriate position.

本発明の基礎通気防水構造によると、立ち上がり部の下方に、通気孔に向かって下り勾配の水受け部が形成されているので、立ち上がり部を越えて浸入した雨水が立ち上がり部の屋内面を伝って流下した場合に、水受け部が当該流下した雨水を受けて通気孔に向かって流して屋外に排出することができる。 According to the basic ventilation waterproof structure of the present invention, since the water receiving portion having a downward slope toward the ventilation hole is formed below the rising portion, rainwater that has entered the rising portion travels along the indoor surface of the rising portion. When the water flows down, the water receiving portion can receive the rainwater that has flowed down, flow toward the vent hole, and be discharged outdoors.

本発明の基礎通気防水構造によると、通気孔から導入された外気が基礎内に侵入する床下換気経路と、内外壁間の壁体内通気層に侵入する壁体内通気経路とを備え、壁体内通気経路にメッシュ材が配置されるので、外気に含まれる雨水が当該外気の侵入に伴って垂れ部と立ち上がり部との間の間隙を通過したとしても、基礎水切材の上端の高さで外気は通過するとともに雨水はメッシュ材に当って壁体内通気経路から壁体内通気層に浸入することを抑制できる。 According to the basic ventilation waterproof structure of the present invention, it is provided with an underfloor ventilation path through which outside air introduced from the ventilation hole enters the foundation, and a wall ventilation path through which the wall ventilation layer enters between the inner and outer walls. Since the mesh material is arranged in the path, even if rainwater contained in the outside air passes through the gap between the drooping part and the rising part as the outside air enters, the outside air is at the height of the upper end of the basic drainage material. While passing, rainwater can be prevented from hitting the mesh material and entering the wall ventilation layer from the wall ventilation path.

基礎水切材９は、建物の基礎の外周の立ち上がりの全面に亘って設けられる長手材である。基礎水切材９の上面は、屋外方向に下り勾配の勾配部９０が形成されており、屋内側の端部が鉛直方向に立ち上がる立ち上がり部９１を形成している。立ち上がり部９１の上端には屋外方向に突出する突出部９２が形成されている。基礎水切材９の屋外側の面は、上部及び下部が屋外方向に突出し、中間部が屋内方向に凹んだ形状となっている。また基礎水切材９の下端面に通気孔９３が形成されており、基礎水切材９の下端の屋内側には基礎の天端面２の縁と当接するひれ部９４が形成されている。なお、基礎水切材９の通気孔９３は外気を通過させることができればよく、例えば虫除けの網が張られていてもよい。 The foundation draining material 9 is a longitudinal member provided over the entire surface of the outer periphery of the foundation of the building. On the upper surface of the foundation drainer 9, a slope portion 90 having a downward slope is formed in the outdoor direction, and a rising portion 91 in which an end portion on the indoor side rises in the vertical direction is formed. A protruding portion 92 that protrudes in the outdoor direction is formed at the upper end of the rising portion 91. The surface on the outdoor side of the foundation drainer 9 has a shape in which an upper part and a lower part protrude in the outdoor direction and a middle part is recessed in the indoor direction. A vent hole 93 is formed in the lower end surface of the foundation drainer 9, and a fin portion 94 that abuts the edge of the top end surface 2 of the foundation is formed on the indoor side of the lower end of the foundation drainer 9. In addition, the ventilation hole 93 of the basic drainage material 9 should just be able to let external air pass, for example, the net | network of the insect repellent may be stretched.

基礎水切材９は下端の屋内側のひれ部９４の上には、上方に立ち上がる屋内壁部９５を形成している。通気孔９３から流入する外気は基礎水切材９の屋外側の面と屋内壁部９５との間を上方に向かって通過し、基礎水切材９の上面の勾配部９０に当って床下換気経路５ａ及び壁体内通気経路５ｂに導入される。屋内壁部９５の上端は、屋外側に折り返される折り返し部９６が形成されており、基礎水切材９の下端面の通気孔９３から侵入する外気に含まれる雨水の一部をこの折り返し部９６で捕捉して、雨水の浸入を抑制している。 The base draining material 9 forms an indoor wall portion 95 rising upward on the indoor fin portion 94 at the lower end. The outside air flowing in from the vent hole 93 passes upward between the outdoor side surface of the basic drainage material 9 and the indoor wall portion 95, hits the sloped portion 90 on the upper surface of the basic drainage material 9, and the underfloor ventilation path 5a. And introduced into the wall ventilation path 5b. At the upper end of the indoor wall portion 95, a folded portion 96 that is folded back to the outdoor side is formed, and a part of rainwater contained in the outside air that enters from the vent hole 93 on the lower end surface of the basic draining material 9 is formed by this folded portion 96. Captures and suppresses the intrusion of rainwater.

本実施形態の基礎通気防水構造１によると、外壁パネル４の垂れ部８と基礎水切材９の立ち上がり部９１とは互いに平行に配置されており、立ち上がり部９１上端の突出部９２と垂れ部８下端の下折部８１とが互いに接近方向に突出している。これによって、外壁パネル４の下端部と基礎水切材９の上面との間の隙間を細くして、当該隙間からの雨水等の浸入を抑制することができる。しかも、外壁パネル４に垂れ部８が設けられることで、外壁パネル４が成形や養生の際に設計寸法との誤差が生じても、垂れ部８と立ち上がり部９１との間隙で誤差を吸収することができ、一定の防水性を保つことができる。また、垂れ部８と立ち上がり部９１との間の隙間は下折部８１及び突出部９２によってより間隙を小さくすることができ、垂れ部８及び立ち上がり部９１の間で下折部８１及び突出部９２の間の空間が複雑な経路となるので、侵入する外気の勢いを緩めて、外気とともに浸入する雨水をこの空間で止めることができる。また、立ち上がり部９１の上端に突出部９２が設けられていることで、この突出部９２が水返しとなって雨水の浸入をより抑制することができる。 According to the basic ventilation structure 1 of the present embodiment, the drooping portion 8 of the outer wall panel 4 and the rising portion 91 of the basic drainage material 9 are arranged in parallel to each other, and the protruding portion 92 and the dripping portion 8 at the upper end of the rising portion 91 are arranged. The lower folding portion 81 at the lower end protrudes in the approaching direction. Thereby, the clearance gap between the lower end part of the outer wall panel 4 and the upper surface of the foundation draining material 9 can be made thin, and infiltration of rain water etc. from the said clearance gap can be suppressed. In addition, since the drooping portion 8 is provided on the outer wall panel 4, even if the outer wall panel 4 has an error from the design dimension during molding or curing, the error is absorbed by the gap between the drooping portion 8 and the rising portion 91. Can maintain a certain level of waterproofness. Further, the gap between the drooping portion 8 and the rising portion 91 can be further reduced by the lower folding portion 81 and the protruding portion 92, and the lower folding portion 81 and the protruding portion are interposed between the dripping portion 8 and the rising portion 91. Since the space between 92 becomes a complicated route, the momentum of the outside air entering can be relaxed, and rainwater entering with the outside air can be stopped in this space. Moreover, since the protrusion 92 is provided at the upper end of the rising portion 91, the protrusion 92 can return to the water and further suppress the intrusion of rainwater.

以上のように、本実施形態の基礎通気防水構造１によると、外壁パネル４の下端面と基礎水切材９の上面との間を湿式のシーリング剤でシールしないので、シーリング処理に係るコストや手間を省くことができ、尚且つ、シーリング処理をしなくとも基礎水切材９に求められるレベルの防水性を達成することができる。 As described above, according to the basic ventilation structure 1 of the present embodiment, the space between the lower end surface of the outer wall panel 4 and the upper surface of the basic drainage material 9 is not sealed with a wet sealing agent, so the cost and labor involved in the sealing process are reduced. In addition, it is possible to achieve the level of waterproofness required for the basic drainage material 9 without performing a sealing treatment.

Since the structure of the mounting bracket 10 is the same as that of the first embodiment, the description thereof is omitted.

基礎水切材９の上面は、屋外方向に下り勾配の勾配部９０が形成されており、屋内側の端部が鉛直方向に立ち上がる立ち上がり部９１を形成している。立ち上がり部９１の上端には屋外方向に突出する突出部９２が形成されている。本実施形態における突出部９２は軟質樹脂により形成されている。基礎水切材９の屋外側の面、下端面、及び屋内側のひれ部９４などの構成は、第一実施形態と同様であるので説明を省略する。 On the upper surface of the foundation drainer 9, a slope portion 90 having a downward slope is formed in the outdoor direction, and a rising portion 91 in which an end portion on the indoor side rises in the vertical direction is formed. A protruding portion 92 that protrudes in the outdoor direction is formed at the upper end of the rising portion 91. The protrusion 92 in the present embodiment is made of a soft resin. The configurations of the outdoor side surface, the lower end surface, the indoor side fin portion 94, and the like of the foundation drainer 9 are the same as those in the first embodiment, and thus the description thereof is omitted.

本実施形態の基礎通気防水構造１によると、外壁パネル４の垂れ部８に向かって、軟質樹脂の突出部９２が突出しており、垂れ部８との間に少しの隙間が設けられている。このように、突出部９２が、軟質樹脂により形成されるので、外壁パネルの寸法誤差で、垂れ部８と突出部９２とが干渉する位置に配置された場合でも、図４に示すように、突出部９２が変形して基礎水切材９を適切な位置に収めることができる。 According to the basic ventilation structure 1 of the present embodiment, the protruding portion 92 of the soft resin protrudes toward the hanging portion 8 of the outer wall panel 4, and a small gap is provided between the protruding portion 92 and the hanging portion 8. Thus, since the protrusion 92 is formed of a soft resin, even when the drooping portion 8 and the protrusion 92 are arranged at positions where they interfere with each other due to a dimensional error of the outer wall panel, as shown in FIG.

At the upper end of the indoor wall portion 95, a water receiving portion 97 having a downward slope toward the vent hole 93 is formed.

水受け部９７は、その上方に基礎水切材９の立ち上がり部９１が配置されており、外壁パネル４と基礎水切材９の間を通過して屋内側に入り込んだ雨水のうち、立ち上がり部９１の屋内面に水滴状に付着した雨水が、当該立ち上がり部９１の屋内面を伝って流下する場合に、立ち上がり部９１の下方で、水受け部９７が当該流下した雨水を受けて通気孔９３に向かって流し屋外に排出することができる。 The water receiving portion 97 has a rising portion 91 of the base draining material 9 disposed above the water receiving portion 97. Of the rainwater that has passed between the outer wall panel 4 and the basic draining material 9 and entered the indoor side, When rainwater adhering to the indoor surface in the form of water droplets flows down along the indoor surface of the rising portion 91, the water receiving portion 97 receives the rainwater that has flowed down to the vent hole 93 below the rising portion 91. It can be discharged outdoors.

〔第五実施形態〕
次に、第五実施形態について図７を参照しつつ説明する。第五実施形態は、外壁パネル４と壁フレーム３との間にメッシュ材１５が配置される他は、第一実施形態と同様の構成であるので、同一の符号を付して説明を省略する。本実施形態の基礎通気防水構造１は、外壁パネル４と壁フレーム３との間にメッシュ材１５が挟まれるように配置されており、メッシュ材１５は、少なくとも基礎水切材９の上端と同じ高さの位置に配置されている。メッシュ材１５は、空気を通過させることができる多数の孔が設けられるシート状であり、網状に限定されるものではない。なお、捨て水切７の中間部には屋外側に突出する突出ひれ１６が形成されているので、メッシュ材１５が落下することを防止することができる。 [Fifth embodiment]
