Description

【0001】
【発明の属する技術分野】
この発明は、幕板と、その下方に位置して建物躯体から外方に向かって延びる庇等の附属屋根部とを備えた建物躯体の防水構造に関する。
【0002】
【先行技術】
図2は、従来の建物躯体の防水構造の縦断面図を示すものである。
従来、幕板110の下方に隣接する位置に、建物躯体150から外方に向かって延びる庇131となる附属屋根部130が形成される場合があった。かかる場合、その庇131等の附属屋根部130と幕板110との間には、他の建物躯体150の外壁面に形成されているサイディング120と同様の材質からなり、上下方向の長さが短い短尺長さの短尺サイディング121が形成されている。これらのサイディング120及び短尺サイディング121は、建物躯体150である壁パネル151の表面に釘等により横方向に固定された木質からなる胴縁140の反建物躯体側に固定されている。なお、壁パネル151の反建物躯体側には、幕板110の上方の一部にシート状の防水シート182が貼付され、幕対110の全面に防水紙181が貼付され、建物躯体150の防水性を担保している。そして、かかる短尺サイディング121と、幕板110及び附属屋根部130との間には、コーキング材160が充填され、建物躯体150に雨水等が浸入することを抑えている。
【0003】
【発明が解決しようとする課題】
しかし、上記した従来の建物躯体の防水構造は、短尺サイディング121の端部と、幕板110及び附属屋根部130との間の隙間から雨水等が浸入しないようにコーキング材160により隙間を埋めなければならず、防水処理に手間が掛かり、また、見栄えもあまり良くないという第一の問題点があった。
【0004】
さらに、幕板110と附属屋根部130との間の狭い範囲に適応する短尺サイディング121を形成しなければならず、セラミック材等からなるサイディング120を必要な長さに切断等するのは容易ではないという第二の問題点があった。
そこで、請求項1記載の発明は、上記した従来の技術の有する第一及び第二の問題点に鑑みてなされたものであり、その目的とするところは、短尺サイディングを必要とせず、防水処理も容易で、外観も良好な建物躯体の防水構造を提供しようとするものである。
【0005】
これに加え、この請求項1記載の発明は、立ち上がり部を凹部内に差し込むだけで、両者間の防水性を担保することができ、防水処理が容易で、外観も良好な建物躯体の防水構造を提供しようとするものである。
請求項2記載の発明は、請求項1記載の発明と同様に、短尺サイディングを必要とせず、また防水処理も容易で、外観も良好な建物躯体の防水構造を提供しようとするものである。
【0006】
【0007】
【0008】
【課題を解決するための手段】
本発明は、上記した目的を達成するためのものである。
請求項1記載の発明は、幕板(10)と、その下方に位置して建物躯体(50)から外方に向かって延びる附属屋根部(30)との間を塞いで水の浸入を抑える防水部(70)を備えた建物躯体(50)の防水構造であって、防水部 (70) は、附属屋根部 (30) の上面から上方に向かって立ち上がる立ち上がり部 (71) を備え、幕板 (10) は、その下部に位置して下方に向かって開口する凹部 (11) と、この凹部 (11) 内に形成される防水充填材 (12) とを備え、前記立ち上がり部 (71) の上端が、凹部 (11) 内の防水充填材 (12) の内部に差し込まれていることを特徴とする。
【0009】
なお、ここで、附属屋根部(30)とは、建物躯体(50)から外方に向かって延びる屋根を有しているものであれば良いものであって、例えば、庇(31)の上面や建物躯体のうち部屋が外側に張り出している部分の上面に形成されるものである。また、附属屋根部(30)の上面に形成されているのは、薄鋼板による瓦またはセラミック等による窯業系の瓦等のいずれも含まれるものである。
【0010】
また、ここで、「幕板(10)」は、建物躯体(50)の上下階の外壁のサイディング(20)の継ぎ目に形成されるものであって、上下階の間の床際に位置する胴差しの端面を覆うものや、建物躯体(50)の外観上のアクセントとなるようなもの等を含むものである。そして、この「幕板(10)」には、塩ビ鋼板等によるものや、窯業系によるもの等を含むものである。
【0011】
【0012】
【0013】
また、ここで、防水充填材(12)とは、立ち上がり部(71)を差し込むことにより、幕板(10)の凹部(11)内面と立ち上がり部(71)の表面との間に隙間なく充填された状態を形成し、両者の間から雨水が浸入しないものであれば良いものである。例えば、ゴム、軟質樹脂等を含むものである。
本発明は、防水部(70)が、附属屋根部(30)の上面から上方に向かって立ち上がる立ち上がり部(71)を備え、この立ち上がり部(71)が幕板(10)の下部の凹部(11)内の防水充填材(12)の内部に差し込まれている。すなわち、凹部(11)と立ち上がり部(71)との間には、防水充填材(12)が充填された状態となっている。このため、立ち上がり部(71)と凹部(11)との間から水が浸入することがなく、またこれら両者間の継ぎ目が反建物躯体側の表面に露出するようなことがなく、防水処理を容易にすることができる。これにより、附属屋根部(30)から幕板(10)まで、連続して水の浸入を抑えることができる。
すなわち、幕板 (10) の表面に沿って流れ落ちる雨水は、防水部 (70) の立ち上がり部 (71) の反建物躯体側の表面に伝わり、そのまま防水部 (70) の立ち上がり部 (71) の表面に沿って下方に流れ落ちる。すなわち、幕板 (10) や防水部 (70) の表面を流れ落ちる雨水が、その表面に露出する防水処理を施した継ぎ目の表面上を、直接伝わるようなことがなく、防水性を担保することができる。また、幕板 (10) と防水部 (70) との間の継ぎ目が反建物躯体側の表面に露出しないため、建物外観を良好なものに維持することができる。
さらに、附属屋根部(30)と幕板(10)との間に防水用に別の部材を形成すると、防水処理を必要とする箇所は、その防水部材と幕板(10)との間、及び、その防水部材と附属屋根部(30)との間の計二箇所、必要になるが、本発明では、附属屋根部(30)から直接、幕板(10)の下部にまで立ち上がっているため、防水処理を必要とするのは、かかる立ち上がり部(71)と幕板(10)との間の一箇所で済み、防水処理を容易にすることができる。
【0014】
また、現場組立施工における立ち上がり部(71)と幕板(10)との間の防水処理の作業も、立ち上がり部(71)を凹部(11)内の防水充填材(12)の内部に下方から差し込むだけで、立ち上がり部(71)の上端に防水充填材(12)が密着し、立ち上がり部(71)の表面と凹部(11)の内面との間の隙間が無くなり、両者間の防水処理が終了する。このように、防水処理の作業自体も、簡単なものにすることができる。
【0015】
請求項2記載の発明は、上記した請求項1記載の発明とほぼ同様に、幕板 (10) と、その下方に位置して建物躯体 (50) から外方に向かって延びる附属屋根部 (30) との間を塞いで水の浸入を抑える防水部 (70) を備えた建物躯体 (50) の防水構造であって、防水部(70)は、附属屋根部(30)の上面から上方に向かって立ち上がる立ち上がり部(71)を備え、幕板(10)は、その下部に位置して下方に向かって開口する凹部(11)を備え、この凹部(11)の内部に前記立ち上がり部(71)の上端が差し込まれ、立ち上がり部(71)と凹部(11)との間にはコーキング材(61)による防水処理が施されていることを特徴とする。
【0016】
なお、ここで、「コーキング材(61)」とは、立ち上がり部(71)を凹部(11)の内部に差し込んだ後、立ち上がり部(71)の上端と凹部(11)の内面との間に充填されて、両者の水密性や気密性を確保することができるものであれば良いものである。
また、この「コーキング材(61)」は、油脂や樹脂や無機質の充填剤を練り混ぜたパテ状の湿式性のものや、ゴムや軟質樹脂等の乾式性のもの等の両者を含むものである。
【0017】
本発明は、立ち上がり部(71)が幕板(10)の下部の凹部(11)内に差し込まれ、この凹部(11)と立ち上がり部(71)との間にコーキング材(61)による防水処理が施されている。このため、立ち上がり部(71)と凹部(11)との間から水が建物躯体(50)に向かって浸入することがなく、またこれら両者間の継ぎ目が反建物躯体側の表面に露出するようなことがなく、防水処理を容易にすることができる。これにより、附属屋根部(30)から幕板(10)まで、連続して水の浸入を抑えることができる。
すなわち、幕板 (10) の表面に沿って流れ落ちる雨水は、防水部 (70) の立ち上がり部 (71) の反建物躯体側の表面に伝わり、そのまま防水部 (70) の立ち上がり部 (71) の表面に沿って下方に流れ落ちる。すなわち、幕板 (10) や防水部 (70) の表面を流れ落ちる雨水が、その表面に露出する防水処理を施した継ぎ目の表面上を、直接伝わるようなことがなく、防水性を担保することができる。また、幕板 (10) と防水部 (70) との間の継ぎ目が反建物躯体側の表面に露出しないため、建物外観を良好なものに維持することができる。
【0018】
また、立ち上がり部(71)は、附属屋根部(30)から直接、幕板(10)の下部にまで立ち上がっているため、防水処理を必要とするのは、かかる立ち上がり部(71)と幕板(10)の凹部(11)との間の一箇所だけで済み、防水処理を容易にすることができる。

【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて、更に詳しく説明する。
図1は、本発明の第一の実施の形態を示すものであり、建物躯体の防水構造の縦断面図を示すものである。
まず、本実施の形態の構成について説明する。
【0025】
本実施の形態に係る建物躯体50の防水構造は、幕板10と、その下方に位置して建物躯体50から外方に向かって延びる附属屋根部30との間を塞いで水の浸入を抑える防水部70を備えたものである。なお、建物躯体50は、木質からなる壁パネル51から形成されているものであって、この壁パネル51は、特に図示しないが、四角枠状の枠材及びこの枠材の枠内を塞ぐ面材から形成されているものである。そして、幕板10は、上下階の間に位置する胴差しに沿って建物周囲の横方向に形成されているものである。また、附属屋根部30は、建物躯体50から外方に向かって突出する庇31の屋根を形成しているものである。また、建物躯体50の表面には、略全面に防水紙81及び一部に防水シート82が貼付され、建物躯体50に雨水が浸入することを抑えている。そして、建物躯体50の防水紙81等の室外側には、木質からなる胴縁40が横方向に沿って固定されている。そして、この胴縁40の室外側表面には、セラミックからなるサイディング20が固定されている。このサイディング20の下端と幕板10の上面との間には、建物躯体50に雨水等が浸入しないようにコーキング材60により防水処理が施されている。
【0026】
前記防水部70の上端は、幕板10の前面の建物躯体50側に位置するとともに幕板10の下端よりも上方に位置している。具体的には、防水部70は、附属屋根部30の建物躯体50側の上面から上方に向かって立ち上がる立ち上がり部71を備えている。そして、幕板10は、その下部に位置して長尺方向に沿って下方に向かって開口する凹溝状の凹部11と、この凹部11内に形成される防水充填材12とを備えている。そして、前記立ち上がり部71の上端が、凹部11内の防水充填材12の内部に差し込まれている。ここで、この防水充填材12は、軟質ゴムから形成されているものであり、立ち上がり部71を差し込むことにより、幕板10の凹部11内面と立ち上がり部71の表面との間に隙間なく充填された状態を形成し、両者の間から雨水が浸入することを抑える役割を有するものである。
【0027】
次に、上記した実施の形態の作用及び効果について説明する。
本実施の形態は、防水部70の上端が、幕板10の前面の建物躯体50側に位置するとともに幕板10の下端よりも上方に位置している。すなわち、防水部70の上端の反建物躯体側が、幕板10により覆われ、防水部70の上端に幕板10が被さった状態となっている。具体的には、防水部70が、附属屋根部30の上面から上方に向かって立ち上がる立ち上がり部71を備え、この立ち上がり部71が幕板10の下部の凹部11内に位置している。そして、この凹部11内の防水充填材12の内部に立ち上がり部71が差し込まれている。
このため、凹部11と立ち上がり部71との間から水が浸入することがない。これにより、附属屋根部30から幕板10まで、連続して水の浸入を抑えることができる。また、幕板10の表面に沿って流れ落ちる雨水は、防水部70の反建物躯体側の表面に伝わり、そのまま防水部70の表面に沿って下方に流れ落ちる。すなわち、幕板10や防水部70の表面を流れ落ちる雨水が、その表面に露出する防水処理を施した継ぎ目の表面上を、直接伝わるようなことがなく、防水性を担保することができる。また、幕板10と防水部70との間の継ぎ目が反建物躯体側の表面に露出しないため、建物外観を良好なものに維持することができる。
【0028】
また、附属屋根部30と幕板10との間に防水用の別の部材を形成すると、防水処理を必要とする箇所は、その防水部材72と幕板10との間、及び、その防水部材72と附属屋根部30との間の計二箇所、必要になるが、本発明では、附属屋根部30から直接、幕板10の下部にまで立ち上がっているため、防水処理を必要とするのは、かかる立ち上がり部71と幕板10との間の一箇所で済み、防水処理を容易にすることができる。
【0029】
また、立ち上がり部71と幕板10との間の防水処理も、立ち上がり部71を凹部11内の防水充填材12の内部に下方から差し込むだけで、立ち上がり部71の上端に防水充填材12が密着し、立ち上がり部71の表面と凹部11の内面との間の隙間が無くなり、両者間の防水処理が終了する。このように、防水処理の作業自体も、簡単なものにすることができる。
【0030】
なお、上述した実施例では、凹部11の内部に予め防水充填材12を充填した後、立ち上がり部71をその防水充填材12の内部に差し込んでいたが、凹部11内に予め防水充填材12を充填することなく、立ち上がり部71を凹部11の内部に差し込み、その後、立ち上がり部71と凹部11との間に湿式性や乾式性のコーキング材61による防水処理を施しても良いものである。これにより、上述したものと同様の防水効果を得ることができる。

Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings.
FIG. 1 shows a first embodiment of the present invention and shows a longitudinal sectional view of a waterproof structure of a building frame.
First, the configuration of the present embodiment will be described.
[0025]
The waterproof structure of the building case 50 according to the present embodiment suppresses the intrusion of water by closing the space between the curtain plate 10 and the attached roof part 30 that is located below and extends outward from the building case 50. A waterproof unit 70 is provided. Note that the building frame 50 is formed of a wooden wall panel 51, and the wall panel 51 is not particularly shown, but is a rectangular frame-like frame member and a surface that covers the inside of the frame member. It is formed from a material. The curtain plate 10 is formed in the lateral direction around the building along the trunk located between the upper and lower floors. The attached roof portion 30 forms a roof of a fence 31 protruding outward from the building frame 50. Further, a waterproof paper 81 and a waterproof sheet 82 are attached to almost the entire surface of the building housing 50 to prevent rainwater from entering the building housing 50. Further, on the exterior side of the waterproofing paper 81 and the like of the building housing 50, a body edge 40 made of wood is fixed along the lateral direction. A siding 20 made of ceramic is fixed to the outer surface of the trunk edge 40. Between the lower end of the siding 20 and the upper surface of the curtain plate 10, a waterproofing process is performed by a caulking material 60 so that rainwater or the like does not enter the building housing 50.
[0026]
The upper end of the waterproof part 70 is located on the building housing 50 side in front of the curtain plate 10 and is located above the lower end of the curtain plate 10. Specifically, the waterproof portion 70 includes a rising portion 71 that rises upward from the upper surface of the attached roof portion 30 on the building housing 50 side. The curtain plate 10 is provided with a concave groove-like concave portion 11 which is located in the lower portion and opens downward along the longitudinal direction, and a waterproof filler 12 formed in the concave portion 11. . The upper end of the rising portion 71 is inserted into the waterproof filler 12 in the recess 11. Here, the waterproof filler 12 is formed of a soft rubber, and is inserted without any gap between the inner surface of the recess 11 of the curtain plate 10 and the surface of the rising portion 71 by inserting the rising portion 71. It has a role to prevent rainwater from entering between the two.
[0027]
Next, the operation and effect of the above-described embodiment will be described.
In the present embodiment, the upper end of the waterproof part 70 is located on the building housing 50 side of the front surface of the curtain plate 10 and is located above the lower end of the curtain plate 10. That is, the anti-building housing side at the upper end of the waterproof part 70 is covered with the curtain plate 10, and the curtain board 10 is covered with the upper end of the waterproof part 70. Specifically, the waterproof portion 70 includes a rising portion 71 that rises upward from the upper surface of the attached roof portion 30, and the rising portion 71 is located in the recess 11 at the bottom of the curtain plate 10. A rising portion 71 is inserted into the waterproof filler 12 in the recess 11.
For this reason, water does not enter from between the concave portion 11 and the rising portion 71. As a result, it is possible to suppress the intrusion of water continuously from the attached roof portion 30 to the curtain 10. Further, the rainwater that flows down along the surface of the curtain plate 10 is transmitted to the surface of the waterproof portion 70 on the side opposite to the building body, and flows down along the surface of the waterproof portion 70 as it is. That is, the rainwater flowing down the surface of the curtain plate 10 and the waterproof part 70 does not directly travel on the surface of the seam subjected to the waterproof process exposed on the surface, and the waterproofness can be ensured. In addition, since the joint between the curtain plate 10 and the waterproof part 70 is not exposed on the surface on the anti-building housing side, it is possible to maintain a good appearance of the building.
[0028]
Further, when another member for waterproofing is formed between the attached roof portion 30 and the curtain plate 10, the places requiring waterproof treatment are between the waterproof member 72 and the curtain plate 10 and the waterproof member. Two places between 72 and the attached roof part 30 are required, but in the present invention, since it rises directly from the attached roof part 30 to the lower part of the curtain plate 10, it is necessary to have waterproofing treatment. Thus, it is only necessary to provide one place between the rising portion 71 and the curtain plate 10, and waterproofing can be facilitated.
[0029]
In addition, the waterproof treatment between the rising portion 71 and the curtain plate 10 is also performed by inserting the rising portion 71 into the waterproof filler 12 in the recess 11 from below, so that the waterproof filler 12 adheres to the upper end of the rising portion 71. As a result, there is no gap between the surface of the rising portion 71 and the inner surface of the recess 11, and the waterproof treatment between the two ends. In this way, the waterproofing work itself can be simplified.
[0030]
In the embodiment described above, after filling the recess 11 with the waterproof filler 12 in advance, the rising portion 71 was inserted into the waterproof filler 12, but the waterproof filler 12 was previously inserted into the recess 11. The rising portion 71 may be inserted into the recess 11 without filling, and then a waterproof treatment with a wet or dry caulking material 61 may be performed between the rising portion 71 and the recess 11. Thereby, the waterproof effect similar to what was mentioned above can be acquired.
