Description

本発明は、建物の基礎とこれに支持される被支持部材との境界部分から建物内部への水の侵入を抑制することができる外壁構造に関する。 The present invention relates to an exterior wall structure that can suppress water from entering the inside of a building from the boundary between the foundation of the building and supported members supported by the foundation.

建物の基礎とこれに支持される外壁との境界部分から建物内部への雨水の侵入を抑制するために、特許文献１に記載のような水切装置が知られている。この水切装置は、布基礎と、この布基礎天端に立設固定したＬ字形の土台金具と、この土台金具上に設置した外壁パネルと、土台金具の略中央高さから布基礎にかけてそれらの屋外領域に被覆形成したモルタル上塗層と、モルタル上塗層の上面に配置した水切板と、を備える。 BACKGROUND ART A drainage device as described in Patent Document 1 is known for suppressing rainwater from entering a building from a boundary between a building foundation and an outer wall supported by the foundation. This draining device consists of a cloth foundation, an L-shaped base metal fitting that is erected and fixed at the top of this cloth foundation, an exterior wall panel installed on this foundation metal fitting, and a structure that extends from approximately the center height of the foundation metal piece to the cloth foundation. The present invention includes a mortar topcoat layer coated on the outdoor area, and a drainage board disposed on the top surface of the mortar topcoat layer.

モルタル上塗層の上方から降り注いだ雨水は、水切板により一旦受け止められた後、モルタル上塗層の屋外面を伝って地上へ排水される。雨水がモルタル上塗層の上面から布基礎の天端に向けて浸み込むことがないので床下空間への雨水の侵入を防止することができる。 Rainwater falling from above the mortar topcoat layer is once caught by the drainage board, and then drained to the ground along the outdoor surface of the mortar topcoat layer. Since rainwater does not seep from the upper surface of the mortar overcoat layer toward the top of the cloth foundation, it is possible to prevent rainwater from entering the space under the floor.

しかし、特許文献１に記載のようにモルタル自体は水の透過を許容する性質を有するため、特許文献１に記載の水切装置においては、例えば洪水が発生して水位が布基礎天端よりも高くなると、水がモルタル上塗層の屋外面から建物内部に向かって侵入するおそれがある。 However, as described in Patent Document 1, the mortar itself has a property of allowing water to pass through, so in the draining device described in Patent Document 1, for example, when a flood occurs, the water level is higher than the top of the fabric foundation. If this happens, water may enter the building from the exterior surface of the mortar overcoat.

It has an upper part. Therefore, it is possible to suppress water from entering through the boundary portion while maintaining the height of the first support surface that supports the supported member.

したがって、建物全体の高さ位置を上げる、または、被支持部材の長さを短くする等の特殊な設計を行うことなく、洪水時等における水の侵入を効果的に抑制することができる。 Therefore, it is possible to effectively suppress water intrusion during floods, etc., without special design such as raising the height of the entire building or shortening the length of supported members.

洪水等の発生により水位が上昇した状況において、基礎とこれに支持される被支持部材との境界部分からの水の侵入を抑制するために、例えば、基礎における被支持部材を支持するための面の高さを上げることが考えられる。しかし、この場合、建物全体の高さ位置を上げる、または、基礎を高くした部分に支持される被支持部材の長さを短くする等、通常の仕様とは異なる設計が必要となる。
これに対し、本発明の外壁構造によれば、水の透過を抑制する特性を持つ基礎自体（第１基礎部）が被支持部材と第１支持面との境界部分を外側から覆う第１立上部を有している。そのため、被支持部材を支持する第１支持面の高さを維持したまま、前記境界部分を通じた水の侵入を抑制することができる。
したがって、建物全体の高さ位置を上げる、または、被支持部材の長さを短くする等の特殊な設計を行うことなく、洪水時等における水の侵入を効果的に抑制することができる。
Further, an external wall structure according to the present invention is an external wall structure of a building, and includes a foundation of the building and a supported member supported on the foundation, and the foundation supports the supported member. a first body portion having a first support surface for supporting the supported member and the first body portion extending upward from the first support surface from a portion of the first body portion outside the first support surface; a first base portion including a first raised portion that covers the first boundary portion from the outside in order to suppress water intrusion through the first boundary portion that is the boundary portion with the support surface; The member has an opening forming part in which an opening for communicating between the outside and the inside of the building is formed, and the foundation has the opening in a region below the upper end of the first standing part. It is preferable to further include a second base part that has a second support surface for supporting the opening forming part so as to open and is provided adjacent to the first base part.
In situations where the water level rises due to the occurrence of a flood, etc., in order to suppress the intrusion of water from the boundary between the foundation and the supported members supported by the foundation, for example, a surface for supporting the supported members on the foundation is installed. It is possible to raise the height of the However, in this case, a design different from normal specifications is required, such as raising the height of the entire building or shortening the length of the supported member supported by the raised part of the foundation.
On the other hand, according to the outer wall structure of the present invention, the foundation itself (the first foundation part), which has the property of suppressing water permeation, is the first upright part that covers the boundary between the supported member and the first support surface from the outside. It has an upper part. Therefore, it is possible to suppress water from entering through the boundary portion while maintaining the height of the first support surface that supports the supported member.
Therefore, it is possible to effectively suppress water intrusion during floods, etc., without special design such as raising the height of the entire building or shortening the length of supported members.

さらに、本発明によれば、第２基礎部は、第１立上部の上端部よりも下方の領域において開口部を開放するように開口形成部を支持するための第２支持面を有する。このため、通常時（洪水等による水位の上昇の無い状況）は、開口部による採光を有効に図ることができる。
Furthermore, according to the present invention , the second base part has a second support surface for supporting the opening forming part so as to open the opening in a region below the upper end part of the first upright part. Therefore, during normal times (situations where there is no rise in water level due to flooding, etc.), the openings can effectively bring in light.

一方、上記のように第１立上部の上端部よりも下方の領域に開口部が配置されている場合、洪水等により水位が開口部下端部よりも上がった状況において、開口部における水位以下の領域を外側から覆う必要がある。 On the other hand, if the opening is located in a region below the upper end of the first upright part as described above, in a situation where the water level rises above the lower end of the opening due to a flood, etc., the water level at the opening or lower It is necessary to cover the area from the outside.

そこで、前記外壁構造において、前記基礎は、前記被支持部材を支持するための第３支持面を有するとともに前記開口部の開口幅方向における前記第１基礎部の反対側で前記第２基礎部に隣接する第３本体部と、前記第３本体部における前記第３支持面よりも外側の部分から前記第３支持面よりも上方に延びるとともに前記基礎と前記外壁との境界部分である第３境界部分を通じた水の侵入を抑制するために前記境界部分を外側から覆う第３立上部と、を含む第３基礎部をさらに有し、当該外壁構造は、水の侵入を抑制するための止水部材を、前記開口部における前記第１立上部の上端部及び前記第３立上部の上端部よりも下方の領域を外側から覆った状態で前記第１立上部から前記第３立上部に亘って取り付けるための取付手段をさらに有するのが好ましい。 Therefore, in the outer wall structure, the foundation has a third support surface for supporting the supported member, and is connected to the second foundation on the opposite side of the first foundation in the opening width direction of the opening. a third boundary that extends upward from the third support surface from a portion of the third body portion outside the third support surface and is a boundary between the foundation and the outer wall; The outer wall structure further includes a third foundation part that covers the boundary part from the outside to suppress water intrusion through the part, and the outer wall structure has a water stopper part to suppress water intrusion through the boundary part. The member is extended from the first upright part to the third upright part in a state that covers an area below the upper end of the first upright part and the upper end of the third upright part in the opening from the outside.

Therefore, even if movement of the water stop member in the inside and outside directions of the building is restricted, the water stop member can be attached to and removed from the attachment means by moving the water stop member in the vertical direction. .

前記外壁構造は、前記止水部材を前記第１立上部又は前記第３立上部と前記被支持部材との間に収納するための収納部をさらに有するのが好ましい。 It is preferable that the outer wall structure further includes a storage part for storing the water stop member between the first upright part or the third upright part and the supported member.

この構成によれば、開口部に隣接した位置である第１立上部又は第３立上部と被支持部材との間に止水部材を収納することができる。このため、洪水時等において水位が上昇する過程で、第１立上部と第３立上部との間に位置する開口部を通じて迅速に止水部材を基礎に取り付けることができる。 According to this configuration, the water stop member can be stored between the first upright portion or the third upright portion, which is located adjacent to the opening, and the supported member. Therefore, in the process of rising water level during a flood or the like, the water stop member can be quickly attached to the foundation through the opening located between the first rising part and the third rising part.

以上説明したように、本発明の外壁構造によれば、基礎とこれに支持される被支持部材との境界部分から建物内部への水の侵入を効果的に抑制することができる。 As explained above, according to the outer wall structure of the present invention, it is possible to effectively suppress water from entering the building from the boundary between the foundation and the supported member supported by the foundation.

The inner wall 2 is arranged on the upper surface of the edge of the floor 8. Regarding the materials of the floor 8 and the inner wall 2, the detailed explanation will be omitted since the well-known floor and inner wall are used in this embodiment.

柱９は、内壁２の建物外側において第１～第３支持面１２ａ、２０ａ、３２ａに支持されている。柱９は、鉛直方向からの荷重を受けるために上下方向に延びるとともに、外壁パネル４を支持するために左右方向に並んで配置されている。柱９としては、本実施形態では図２及び図３に示すように、リップ溝形鋼（Ｃ型鋼）が用いられるが、柱９の構造及び材質はこれに限られない。例えば、柱９として木製のものを採用することもできる。 The pillar 9 is supported by first to third support surfaces 12a, 20a, and 32a on the outside of the building of the inner wall 2. The pillars 9 extend in the vertical direction to receive loads from the vertical direction, and are arranged side by side in the left-right direction to support the outer wall panel 4. In this embodiment, as shown in FIGS. 2 and 3, lip channel steel (C-shaped steel) is used as the pillar 9, but the structure and material of the pillar 9 are not limited to this. For example, the pillar 9 may be made of wood.

It has two windows 44, 44 provided in the body 42. An opening A is formed inside the frame 42 to communicate the inside and outside of the building. The opening A is formed in the frame 42.

取付手段７０は、止水部材７を第１立上部１４から第３立上部３４に亘って取り付けるためのものである。具体的に、取付手段７０は、図１及び図２に示すように、第１立上部１４の右側の端面に設けられるとともに止水部材７の左端部に係止される第１係止部７２と、第３立上部３４の左側の端面に設けられるとともに止水部材７の右端部に係止される第３係止部７４と、を有する。 The attachment means 70 is for attaching the water stop member 7 from the first upright part 14 to the third upright part 34. Specifically, as shown in FIGS. 1 and 2, the attachment means 70 includes a first locking portion 72 that is provided on the right end surface of the first upright portion 14 and is locked on the left end of the water stop member 7. and a third locking portion 74 that is provided on the left end surface of the third upright portion 34 and is locked to the right end of the water stop member 7.

本実施形態で用いられる止水部材７は、図１に示すように、第１立上部１４と第３立上部３４との間を覆うことができる大きさを有する板材である。具体的に、止水部材７の高さは、第１立上部１４及び第３立上部３４の高さにほぼ等しく、止水部材７の幅方向の長さは、第１立上部１４の右端面と第３立上部３４の左端面との間の長さにほぼ等しい。止水部材７の材質としては、鉄やアルミニウム等の金属、又は樹脂等が用いられる。 The water stop member 7 used in this embodiment is a plate material having a size that can cover the space between the first upright part 14 and the third upright part 34, as shown in FIG. Specifically, the height of the water cutoff member 7 is approximately equal to the height of the first raised portion 14 and the third raised portion 34, and the length of the water cutoff member 7 in the width direction is equal to the right end of the first raised portion 14. The length between the surface and the left end surface of the third upright portion 34 is approximately equal. As the material of the water stop member 7, metal such as iron or aluminum, resin, or the like is used.

止水部材７は、第１立上部１４から第３立上部３４に亘って取り付けられた状態で、第１立上部１４の上端部及び第３立上部３４の上端部よりも下方の領域における開口部Ａへの建物外側からの水の侵入を抑制する。 The water stop member 7 is installed from the first upright part 14 to the third upright part 34, and has an opening in a region below the upper end of the first upright part 14 and the upper end of the third upright part 34. Prevent water from entering Part A from outside the building.

第１係止部７２は、図１、図２、図４に示すように、右方向に開くとともに、上下方向に延びる溝７２ａを有する。第３係止部７４は、図１、図２に示すように、左方向に開くとともに、上下方向に延びる溝７４ａを有する。これら第１、第３係止部７２、７４の溝７２ａ、７４ａは、止水部材７が嵌合可能となるように、止水部材７の厚みとほぼ同じ長さの幅を有する。止水部材７は、これらの溝７２ａ、７４ａに嵌合されることにより、建物内外方向への移動が規制された状態で第１係止部７２及び第２係止部７４に係止される。また、これらの溝７２ａ、７４ａは、基礎５に取り付けられた止水部材７の上方向への移動を許容するために上方向に開口している。これらの溝７２ａ、７４ａの下端部は第２基礎部２０の上面により閉じられており、これにより止水部材７が下方向に抜け落ちることが規制される。 As shown in FIGS. 1, 2, and 4, the first locking portion 72 has a groove 72a that opens rightward and extends vertically. As shown in FIGS. 1 and 2, the third locking portion 74 has a groove 74a that opens leftward and extends vertically. The grooves 72a and 74a of the first and third locking portions 72 and 74 have a width that is approximately the same length as the thickness of the water stop member 7 so that the water stop member 7 can be fitted into the grooves 72a and 74a. By fitting into these grooves 72a and 74a, the water stop member 7 is locked to the first locking part 72 and the second locking part 74 in a state where movement in the inside and outside directions of the building is restricted. . Furthermore, these grooves 72a and 74a are open upward to allow upward movement of the water stop member 7 attached to the foundation 5. The lower end portions of these grooves 72a and 74a are closed by the upper surface of the second base portion 20, thereby preventing the water stop member 7 from falling off downward.

このように、止水部材７は、その左端部が第１係止部７２の溝に係止され、右端部が第３係止部７４の溝に係止されることにより、上下方向への移動が許容されかつ止水部材７の建物内外方向への移動が規制された状態で第１係止部７２及び第３係止部７４に係止される。 In this way, the left end of the water stop member 7 is locked in the groove of the first locking part 72, and the right end is locked in the groove of the third locking part 74, so that the water stop member 7 can be moved in the vertical direction. The water stop member 7 is locked by the first locking part 72 and the third locking part 74 in a state where movement is allowed and movement of the water stop member 7 in the inside and outside directions of the building is restricted.

また、止水部材７の係止状態において、止水部材７と第１係止部７２との間、止水部材７と第３係止部７４との間、止水部材７と第２支持面２０ａとの間には、シール材を設けるのが好ましい。これにより、止水部材７と第１係止部７２、第３係止部７４、第２支持面２０ａとの間をシールし、建物外側からの水の侵入をより効果的に抑制することができる。 In addition, in the locked state of the water stop member 7, there is a gap between the water stop member 7 and the first locking part 72, between the water stop member 7 and the third lock part 74, and between the water stop member 7 and the second support. It is preferable to provide a sealing material between the surface 20a and the surface 20a. Thereby, it is possible to seal between the water stop member 7, the first locking part 72, the third locking part 74, and the second support surface 20a, and more effectively suppress water intrusion from the outside of the building. can.

（施工手順）
以下、基礎５の施工手順、特に第１基礎部１０及び第３基礎部３０の施工手順について、図６及び図７を用いて説明する。 (Construction procedure)
Hereinafter, the construction procedure of the foundation 5, particularly the construction procedure of the first foundation part 10 and the third foundation part 30, will be explained using FIGS. 6 and 7.

まずは、第１支持面１２ａ及び第３支持面３２ａに対応する上面５１ａを有するコンクリート部材５１を形成する。 First, a concrete member 51 having an upper surface 51a corresponding to the first support surface 12a and the third support surface 32a is formed.

具体的に、図６に示すように、上下方向に延びるとともに互いに対向する一対の板状の枠板５５、５５を、地盤Ｈの上に設置する。そして枠板５５にコンクリートを流し込んで硬化させ、コンクリート部材５１を形成する。この時、振動を加えつつコンクリートを硬化させることが好ましい。これにより、コンクリート部材５１の密度を向上させて水の侵入をより効果的に抑制することができる。 Specifically, as shown in FIG. 6, a pair of plate-shaped frame boards 55, 55 that extend in the vertical direction and face each other are installed on the ground H. Then, concrete is poured into the frame plate 55 and hardened to form the concrete member 51. At this time, it is preferable to harden the concrete while applying vibration. Thereby, the density of the concrete member 51 can be improved and water intrusion can be more effectively suppressed.

次に図７に示すように、断面視Ｌ字状のコンクリート部材５３をコンクリート部材５１に隣接した位置に形成する。具体的に、コンクリート部材５３は、コンクリート部材５１の一方側（本実施形態では図７の紙面左側）の面に隣接するとともに上下方向に延びる第１部分と、第１部分の下端部から一方側に延びる第２部分と、を含む。また、第１部分の上端部は、コンクリート部材５１の上面５１ａよりも高い位置まで立ち上がる。 Next, as shown in FIG. 7, a concrete member 53 having an L-shape in cross section is formed at a position adjacent to the concrete member 51. As shown in FIG. Specifically, the concrete member 53 includes a first portion that is adjacent to one side of the concrete member 51 (the left side of the paper in FIG. 7 in this embodiment) and extends in the vertical direction; a second portion extending to. Further, the upper end portion of the first portion rises to a position higher than the upper surface 51a of the concrete member 51.

このようなコンクリート部材５３を形成するために、本実施形態では、図７に示すように枠板５４，５６，５７，５８、を用いる。 In order to form such a concrete member 53, in this embodiment, frame plates 54, 56, 57, and 58 are used as shown in FIG.

具体的に、コンクリート部材５１の外側における地盤Ｈより高く地面Ｇよりも低い位置でコンクリート部材５１の外側面から外側に延びるように枠板５６を設置する。また、枠板５７は、内外方向に所定の厚みを有する。この枠板５７の下面が枠板５６の上面と対向し、枠板５７の内側面がコンクリート部材５１の外側面と対向し、枠板５７がコンクリート部材５１の上端を超えて上に延び、さらに枠板５７の外側面が枠板５６の外側面と同一平面状に位置するように枠板５７を設置する。枠板５４は、枠板５６、５７間で外側に開く開口を閉じるように枠板５６、５７の外側面に密着して配置される。枠板５８の外側面が枠板５７の内側面と対向し、かつ、枠板５８の外側面とコンクリート部材５１の外側面とが同一平面状に位置するように枠板５８をコンクリート部材５１上に設置する。 Specifically, the frame plate 56 is installed outside the concrete member 51 at a position higher than the ground H and lower than the ground G so as to extend outward from the outer surface of the concrete member 51. Further, the frame plate 57 has a predetermined thickness in the inner and outer directions. The lower surface of this frame board 57 faces the upper surface of the frame board 56, the inner surface of the frame board 57 faces the outer surface of the concrete member 51, the frame board 57 extends upward beyond the upper end of the concrete member 51, and further The frame board 57 is installed so that the outer surface of the frame board 57 is located on the same plane as the outer surface of the frame board 56. The frame plate 54 is arranged in close contact with the outer surfaces of the frame plates 56 and 57 so as to close the opening that opens outward between the frame plates 56 and 57. The frame board 58 is placed on the concrete member 51 so that the outer surface of the frame board 58 faces the inner surface of the frame board 57 and the outer surface of the frame board 58 and the outer surface of the concrete member 51 are located on the same plane. to be installed.

このように、枠板５４、５６～５８を設置した状態で、これら枠板５４、５６～５８及びコンクリート部材５１の間に形成された空間、つまり、コンクリート部材５３の断面形状に相当する空間にコンクリートを流し込んで硬化させ、コンクリート部材５３を形成する。これにより、コンクリート部材５１とコンクリート部材５３は一体に形成され、本実施形態の第１基礎部１０又は第３基礎部３０として用いられる。なお、コンクリート部材５３における、コンクリート部材５１の上面５１ａよりも地面Ｇの表面からの高さが高い部分は、第１基礎部１０の第１立上部１４又は第３立上部３４に対応する。 In this way, with the frame plates 54, 56 to 58 installed, the space formed between these frame plates 54, 56 to 58 and the concrete member 51, that is, the space corresponding to the cross-sectional shape of the concrete member 53, is Concrete is poured and hardened to form a concrete member 53. Thereby, the concrete member 51 and the concrete member 53 are integrally formed and used as the first foundation part 10 or the third foundation part 30 of this embodiment. Note that a portion of the concrete member 53 that is higher in height from the surface of the ground G than the upper surface 51a of the concrete member 51 corresponds to the first rising portion 14 or the third rising portion 34 of the first foundation portion 10.

また、次のような方法で一体化をより強固なものにすることができる。すなわち、図７に示すように、コンクリート部材５１における外側面に埋め込みナット６０を埋め込んだ状態で、コンクリート部材５１を硬化させ、枠板５５の取り外し後に、埋め込みナット６０にボルト６１を螺合する。そしてこれら枠板５４、５６～５８及びコンクリート部材５１の間に形成された空間にコンクリートを流し込んでコンクリート部材５３を形成する。これにより、コンクリート部材５１とコンクリート部材５３との一体化をより強固なものにすることができる。 In addition, the integration can be made stronger by the following methods. That is, as shown in FIG. 7, the concrete member 51 is hardened with the embedded nut 60 embedded in the outer surface of the concrete member 51, and after the frame plate 55 is removed, the bolt 61 is screwed into the embedded nut 60. Then, concrete is poured into the space formed between the frame plates 54, 56 to 58 and the concrete member 51 to form the concrete member 53. Thereby, the integration of the concrete member 51 and the concrete member 53 can be made stronger.

なお、コンクリート部材５３の硬化のために、水圧に抵抗するための鉄筋をコンクリート部材５３の内部に配置してもよい。 In addition, in order to harden the concrete member 53, reinforcing bars for resisting water pressure may be placed inside the concrete member 53.

上記手順において、地盤によりコンクリート部材５３の下端部が形成できる場合には、地盤を枠板５６の代わりに用いることにより枠板５６の設置を省略することができる。 In the above procedure, if the lower end of the concrete member 53 can be formed from the ground, the installation of the frame board 56 can be omitted by using the ground instead of the frame board 56.

また、図７の二点鎖線で示すように、止水部材７の高さ、幅、奥行きのそれぞれの寸法よりも大きな寸法を有する枠板５９を枠板５８の一方側に隣接して配置した状態で、コンクリートを流し込んで硬化させることで、第１基礎部１０の立上部１４の凹部を形成することができる。 Further, as shown by the two-dot chain line in FIG. 7, a frame plate 59 having dimensions larger than each of the height, width, and depth of the water stop member 7 is arranged adjacent to one side of the frame plate 58. By pouring and hardening concrete in this state, the recessed portion of the rising portion 14 of the first foundation portion 10 can be formed.

なお、コンクリートが完全に硬化すると、コンクリート部材５１とコンクリート部材５３は一体化される。そのため、図３では、第１基礎部１０におけるコンクリート部材５１、５３の境界線に対応する線を省略している。このことは、図５の第３基礎部３０でも同様である。 Note that when the concrete is completely hardened, the concrete member 51 and the concrete member 53 are integrated. Therefore, in FIG. 3, the line corresponding to the boundary line between the concrete members 51 and 53 in the first foundation part 10 is omitted. This also applies to the third base portion 30 in FIG. 5 .

第２基礎部２０の施工方法については、公知の基礎の施工方法と同様なのでその詳細な説明を省略する。 The method of constructing the second foundation portion 20 is similar to the method of constructing a known foundation, so a detailed explanation thereof will be omitted.

（作用効果）
本実施形態の外壁構造１によれば、水の透過を抑制する性質を有する特性を持つ基礎自体（第１基礎部１０）が被支持部材３と第１支持面１２ａとの境界部分を外側から覆う第１立上部１４を有している。そのため、被支持部材３を支持する第１支持面１２ａの高さを維持したまま、境界部分を通じた水の侵入を抑制することができる。 (effect)
According to the outer wall structure 1 of this embodiment, the foundation itself (the first foundation part 10) having the property of suppressing water permeation extends from the outside at the boundary between the supported member 3 and the first support surface 12a. It has a first raised part 14 for covering. Therefore, while maintaining the height of the first support surface 12a that supports the supported member 3, it is possible to suppress water from entering through the boundary portion.

したがって、建物全体の高さ位置を上げる、または、被支持部材３の長さを短くする等の特殊な設計を行うことなく、洪水時等における水の侵入を効果的に抑制することができる。 Therefore, without special design such as raising the height of the entire building or shortening the length of the supported member 3, it is possible to effectively prevent water from entering during a flood or the like.

また、第２基礎部２０は、第１立上部１４の上端部よりも下方の領域において開口部Ａを開放するように開口形成部４０を支持するための第２支持面２０ａを有する。このため、通常時（洪水等による水位の上昇の無い状況）は、開口部Ａによる採光を有効に図ることができる。 Further, the second base portion 20 has a second support surface 20a for supporting the opening forming portion 40 so as to open the opening A in a region below the upper end portion of the first standing portion 14. Therefore, during normal times (in a situation where there is no rise in water level due to flooding, etc.), the opening A can effectively bring in light.

一方、上記のように第１立上部１４の上端部よりも下方の領域に開口部Ａが配置されている場合、洪水等により水位が開口部Ａの下端部よりも上がった状況において、開口部Ａにおける水位以下の領域を外側から覆う必要がある。 On the other hand, if the opening A is arranged in a region below the upper end of the first rising part 14 as described above, in a situation where the water level rises above the lower end of the opening A due to a flood or the like, the opening It is necessary to cover the area below the water level at A from the outside.

また、止水部材７を基礎５に取り付けるための取付手段７０が設けられているため、開口部Ａにおける第１立上部１４の上端部及び第３立上部３４の上端部よりも下の領域を外側から覆った状態で止水部材７を第１立上部１４から第３立上部３４に亘って取り付けることができる。したがって、上述のように、通常時（洪水等による水位の上昇の無い状況）において開口部Ａによる採光を有効に図りつつ、洪水等により水位が開口部Ａの下端部よりも上に上昇した場合には止水部材７により水の侵入を抑制することができる。 Furthermore, since the attachment means 70 for attaching the water stop member 7 to the foundation 5 is provided, the area below the upper end of the first upright part 14 and the upper end of the third upright part 34 in the opening A is The water stop member 7 can be attached from the first upright part 14 to the third upright part 34 while being covered from the outside. Therefore, as mentioned above, if the water level rises above the lower end of the opening A due to a flood, etc., while effectively lighting the opening A during normal times (situations where there is no rise in water level due to floods, etc.) Intrusion of water can be suppressed by the water stop member 7.

また、第１係止部７２が第１立上部１４に設けられ、第３係止部７４が第３立上部３４に設けられるので、止水部材７を第１係止部７２と第３係止部７４を介して第１立上部１４と第３立上部３４に亘って設けることができる。このため、止水部材７を安定して基礎５に取り付けることができ、開口部Ａからの水の侵入をより一層抑制することができる。 Further, since the first locking portion 72 is provided on the first upright portion 14 and the third locking portion 74 is provided on the third upright portion 34, the water stop member 7 can be connected to the first locking portion 72 and the third locking portion 34. It can be provided across the first upright portion 14 and the third upright portion 34 via the stop portion 74 . Therefore, the water stop member 7 can be stably attached to the foundation 5, and the intrusion of water from the opening A can be further suppressed.

また、取付手段７０は、基礎５に設けられるとともに止水部材７の建物内外方向への移動を規制するように止水部材７を係止するので、洪水等により水位が上昇したときに、止水部材７が水圧により建物内側方向へ倒れるのを抑制することができる。このため、効果的に水の侵入を抑制することができる。 In addition, the attachment means 70 is provided on the foundation 5 and locks the water stop member 7 so as to restrict the movement of the water stop member 7 in the inside and outside directions of the building, so when the water level rises due to a flood etc. It is possible to suppress the water member 7 from falling toward the inside of the building due to water pressure. Therefore, the intrusion of water can be effectively suppressed.

また、取付手段７０は、止水部材７の上下方向への移動を許容するように止水部材７を保持するので、止水部材７の建物内外方向への移動が規制された状態であっても、この止水部材７を上下方向に移動させることによりこの止水部材７を取付手段７０に対して着脱することができる。 In addition, since the attachment means 70 holds the water stop member 7 in a manner that allows the water stop member 7 to move in the vertical direction, the movement of the water stop member 7 in the inside and outside directions of the building is restricted. Also, by moving the water stop member 7 in the vertical direction, the water stop member 7 can be attached to and removed from the attachment means 70.

また、外壁構造１は、止水部材７を第１立上部１４又は第３立上部３４と被支持部材３との間に収納するための収納部６をさらに有するので、開口部Ａに隣接した位置である第１立上部１４又は第３立上部３４と被支持部材３との間に止水部材７を収納することができる。このため、洪水時等において水位が上昇する過程で、第１立上部１４と第３立上部３４との間に位置する開口部Ａを通じて迅速に止水部材７を基礎５に取り付けることができる。 In addition, the outer wall structure 1 further includes a storage part 6 for storing the water stop member 7 between the first upright part 14 or the third upright part 34 and the supported member 3. The water stop member 7 can be housed between the first standing portion 14 or the third standing portion 34 and the supported member 3. Therefore, in the process of rising water level during a flood or the like, the water stop member 7 can be quickly attached to the foundation 5 through the opening A located between the first rising part 14 and the third rising part 34.

（変形例）
前記実施形態は本発明の好ましい具体例を例示したものに過ぎず、本発明は前記実施形態に限定されない。 (Modified example)
The above embodiments are merely illustrative of preferred specific examples of the present invention, and the present invention is not limited to the above embodiments.

前記第１実施形態及び第２実施形態では、建物の窓を止水部材７により外側から覆う場合及び建物の玄関のポーチを止水部材１０７Ａ，１０７Ｂにより外側から覆う場合について説明した。しかし、止水部材を取り付けることができる場所はこれに限られない。例えば、第１実施形態の開口形成部４０の代わりに勝手口を採用し、この勝手口を止水部材７により外側から覆っても良い。この場合、この勝手口への水の侵入を止水部材７により抑制することができる。 In the first and second embodiments, the case where the windows of a building are covered from the outside with the water stop member 7 and the case where the entrance porch of the building is covered from the outside with the water stop members 107A and 107B have been described. However, the locations where the water stop member can be attached are not limited to this. For example, a back opening may be used instead of the opening forming portion 40 of the first embodiment, and this back opening may be covered from the outside with the water stop member 7. In this case, the water stop member 7 can prevent water from entering the back opening.

また、室外機等の機器を収納するために建物外側方向に開口する凹部を有する外壁を用い、この凹部を止水部材により外側から覆っても良い。具体的に、この外壁を支持する基礎は、凹部の左右方向両側に設けられた第１基礎部と、これら第１基礎部の間で凹部を支持するとともに凹部内に機器を載置するための載置部と、を含む。この第１基礎部は、第１実施形態の第１基礎部１０と同様の構成を有する。また、載置部の上端面の地面Ｇからの高さは、第１基礎部の第１支持面の地面Ｇからの高さと略等しくされている。これら第１基礎部の第１立上部には、これら第１立上部に亘って止水部材を取り付けるための取付手段が設けられている。この場合、取付手段を用いて止水部材を第１立上部に取り付けることにより、凹部への水の侵入を抑制し、洪水時等に載置部上の機器を保護することができる。なお、止水部材を用いる代わりに、凹部を外側から覆うように第１立上部と同じ高さの立上部を載置部に設けても良い。 Alternatively, an outer wall having a recess opening toward the outside of the building may be used to house equipment such as an outdoor unit, and the recess may be covered from the outside with a water-stopping member. Specifically, the foundation that supports this outer wall includes first foundations provided on both sides of the recess in the left-right direction, and a foundation for supporting the recess and placing equipment in the recess between these first foundations. A mounting section. This first foundation part has the same configuration as the first foundation part 10 of the first embodiment. Further, the height of the upper end surface of the mounting portion from the ground G is approximately equal to the height of the first support surface of the first base portion from the ground G. Attachment means for attaching a water stop member across these first upright parts is provided on the first upright parts of these first foundation parts. In this case, by attaching the water stop member to the first upright portion using the attachment means, it is possible to suppress water from entering the recess and protect the equipment on the mounting portion in the event of a flood or the like. Note that instead of using the water stop member, a raised part having the same height as the first raised part may be provided on the mounting part so as to cover the recessed part from the outside.

前記第１実施形態では、第１係止部７２と第３係止部７４を用いて止水部材７を左右方向の両端部から係止することにより止水部材７を基礎５に取り付けたが、止水部材７を基礎５に取り付けるための取付手段はこれらに限られない。例えば、第１係止部７２と第３係止部７４を用いるのに加えて、上方向に開くとともに、左右方向に延びる溝を有する第２係止部を第２基礎部２０の上面における第１立上部１４と第３立上部３４との間に設けても良い。この場合、第１係止部７２と第２係止部と第３係止部７４とにより、止水部材７を左右方向の両端部及び下端部から係止することができる。これにより、止水部材７を基礎５に取り付けた状態において、止水部材７の下端部と第２支持面２０ａとの間の隙間から水が侵入するのを第２係止部により抑制することができる。 In the first embodiment, the water stop member 7 is attached to the foundation 5 by using the first locking part 72 and the third locking part 74 to lock the water stop member 7 from both ends in the left and right direction. The attachment means for attaching the water stop member 7 to the foundation 5 are not limited to these. For example, in addition to using the first locking part 72 and the third locking part 74, a second locking part having a groove that opens upward and extends in the left-right direction is installed on the upper surface of the second base part 20. It may be provided between the first upright part 14 and the third upright part 34. In this case, the first locking portion 72, the second locking portion, and the third locking portion 74 can lock the water stop member 7 from both ends and the lower end in the left-right direction. As a result, when the water stop member 7 is attached to the foundation 5, the second locking portion prevents water from entering through the gap between the lower end of the water stop member 7 and the second support surface 20a. I can do it.

前記第１実施形態では、先にコンクリート部材５１を形成し、次いでコンクリート部材５１の隣にコンクリート部材５３を形成するにより第１基礎部１０及び第３基礎部３０を形成したが、第１基礎部１０及び第３基礎部３０の施工方法はこれに限られない。例えば、第１基礎部１０及び第３基礎部３０が結合された形状の空間を区画可能な枠板にコンクリートを流し込むことにより第１基礎部１０及び第３基礎部３０を形成しても良い。 In the first embodiment, the first foundation part 10 and the third foundation part 30 are formed by first forming the concrete member 51 and then forming the concrete member 53 next to the concrete member 51. 10 and the third foundation part 30 are not limited to this method. For example, the first foundation part 10 and the third foundation part 30 may be formed by pouring concrete into a frame plate that can define a space where the first foundation part 10 and the third foundation part 30 are combined.

前記第１実施形態では、基礎５に取り付けられた止水部材７が下方に抜け落ちることを規制するために、第１、第３係止部７２、７４の溝７２ａ、７４ａの下端部を第２基礎部２０の上面により閉じていた。しかし、図１の点線で示すように止水部材７を下方向に取り外すことができるように、溝７２ａ、７４ａの下端部を開口しても良い。具体的には、図２に示すように、溝７２ａ、７４ａが下方向に開口するように第１、第３係止部７２、７４を基礎５の建物外側の面よりも外側に設けても良い。 In the first embodiment, in order to prevent the water stop member 7 attached to the foundation 5 from falling off downward, the lower ends of the grooves 72a and 74a of the first and third locking parts 72 and 74 are It was closed by the upper surface of the base part 20. However, the lower ends of the grooves 72a and 74a may be opened so that the water stop member 7 can be removed downward as shown by the dotted line in FIG. Specifically, as shown in FIG. 2, the first and third locking portions 72 and 74 may be provided on the outside of the building outer surface of the foundation 5 so that the grooves 72a and 74a open downward. good.

これにより、洪水等による水位上昇が発生していないときには、止水部材７を基礎５の建物外側（図２の点線で示す位置）に設置することができる。また、洪水等による水位上昇が発生しているときには、図２の点線で示す位置に設置された止水部材７を下方から容易に第１、第３係止部７２，７４に係止することができる。 Thereby, when the water level is not rising due to flooding or the like, the water stop member 7 can be installed on the outside of the building on the foundation 5 (the position indicated by the dotted line in FIG. 2). Furthermore, when the water level rises due to a flood or the like, the water stop member 7 installed at the position indicated by the dotted line in FIG. 2 can be easily locked to the first and third locking parts 72 and 74 from below. I can do it.

なお、止水部材７を第１、第３係止部７２，７４に係止する手段は特に限定されないが、例えば、止水部材７と第１、第３係止部７２，７４の溝７２ａ、７４ａとの間で発生する摩擦抵抗により止水部材７を第１、第３係止部７２，７４に係止しても良い。 Note that the means for locking the water stop member 7 to the first and third locking parts 72 and 74 is not particularly limited, but for example, the groove 72a of the water stop member 7 and the first and third locking parts 72 and 74 , 74a may be used to lock the water stop member 7 to the first and third locking portions 72, 74.

上述した第１実施形態の変形例は、第２実施形態の変形例としても同様に適用される。 The above-described modification of the first embodiment is similarly applied as a modification of the second embodiment.

その他、本発明の特許請求の範囲内で種々の設計変更が可能であることは言うまでもない。 It goes without saying that various other design changes are possible within the scope of the claims of the present invention.
