以下、本発明の実施の形態について図面を参照して説明する。図１は、本実施の形態の水切り構造１の構成を説明するための断面図で、図２は、その水切り構造１に配置される水切り材７の構成を説明する側面図である。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view for explaining the configuration of the draining structure 1 of the present embodiment, and FIG. 2 is a side view for explaining the configuration of the draining material 7 arranged in the draining structure 1.
本実施の形態の水切り構造１は、建物の床２と壁３との入隅となる隅角部に設けられる。例えば、バルコニーの床と外壁との隅角部、集合住宅における半屋外の内廊下と各住戸の壁との隅角部などに設けられる。 The draining structure 1 of the present embodiment is provided at a corner portion that is a corner between the floor 2 and the wall 3 of the building. For example, it is provided at a corner between a balcony floor and an outer wall, a corner between a semi-outdoor inner corridor and a wall of each dwelling unit in an apartment house, and the like.
本実施の形態では、図５，７に示すように、玄関などの開口部３３に隣接する箇所を例に説明する。この壁３は、壁面となる外壁面３１にタイルなどが貼り付けられた外壁となる。 In the present embodiment, as shown in FIGS. 5 and 7, a description will be given taking a location adjacent to the opening 33 such as a front door as an example. The wall 3 is an outer wall in which a tile or the like is attached to an outer wall surface 31 serving as a wall surface.
一方、この壁３に接続される床２の上面２１には、図３に示すように、防水シート４が敷設される。この防水シート４は、壁３側の側縁部が壁３の下部３２を覆うように立ち上げられて立上げ部４１となる。 On the other hand, a waterproof sheet 4 is laid on the upper surface 21 of the floor 2 connected to the wall 3 as shown in FIG. The waterproof sheet 4 is raised so that the side edge portion on the wall 3 side covers the lower portion 32 of the wall 3 to form a rising portion 41.
立上げ部４１は、例えばタッピンねじ等の固定ネジ４２によって壁３に接合される。固定ネジ４２は、立上げ部４１の延伸方向（水平方向）に間隔を置いて、複数本がねじ込まれる。 The rising portion 41 is joined to the wall 3 by a fixing screw 42 such as a tapping screw. A plurality of fixing screws 42 are screwed at intervals in the extending direction (horizontal direction) of the rising portion 41.
本実施の形態の水切り構造１は、図１に示したように、前述した防水シート４の立上げ部４１と、立上げ部４１の上縁４１１とその上方の外壁面３１とに跨って配置された防水材としての防水テープ５と、立上げ部４１及び防水テープ５を覆う水切り材７と、防水テープ５と水切り材７との間に圧縮された状態で介在される弾性材としての水密材６とによって、主に構成される。 As shown in FIG. 1, the draining structure 1 of the present embodiment is disposed across the rising portion 41 of the waterproof sheet 4, the upper edge 411 of the rising portion 41, and the outer wall surface 31 above the rising portion 41. Waterproof tape 5 as the waterproof material, draining material 7 covering the rising portion 41 and the waterproof tape 5, and watertightness as an elastic material interposed between the waterproof tape 5 and the draining material 7 in a compressed state It is mainly composed of the material 6.
防水テープ５は、防水性及び耐久性に優れた基材と粘着剤とによって形成される。例えば、ゴム基材とブチルゴム系粘着剤とによって構成されたテープを使用することができる。 The waterproof tape 5 is formed of a base material and an adhesive that are excellent in waterproofness and durability. For example, a tape composed of a rubber base material and a butyl rubber adhesive can be used.
変形性能に優れた基材の防水テープ５であれば、外壁面３１に凹凸がある場合でも密着させることができる。特に塑性変形性能を有するゴム基材を使用した場合、凹凸面に密着させた状態を保持させることができる。 If the waterproof tape 5 is a base material excellent in deformation performance, it can be adhered even when the outer wall surface 31 is uneven. In particular, when a rubber base material having plastic deformation performance is used, it is possible to maintain a state of being in close contact with the uneven surface.
一方、水密材６には、低密度で柔軟な発泡体などを使用することができる。例えば、ＥＰＤＭゴム（エチレン・プロピレン・ジエンゴム）発泡体を使用することができる。 On the other hand, the watertight material 6 can be a low-density flexible foam. For example, EPDM rubber (ethylene / propylene / diene rubber) foam can be used.
また、水密材６は、圧縮率によって水密性能が変化するため、所望する水密性能が得られるように、水密材６が配置される隙間の広さに応じて材厚Ｄ２を設定する。 Moreover, since the watertight performance of the watertight material 6 varies depending on the compression ratio, the material thickness D2 is set according to the size of the gap in which the watertight material 6 is disposed so that the desired watertight performance can be obtained.
水切り材７は、図２，７に示すように、ステンレス鋼などの金属板を折り曲げ加工することによって製作される長尺部材である。図２は、水切り材７の端部を示した側面図である。 The draining material 7 is a long member manufactured by bending a metal plate such as stainless steel as shown in FIGS. FIG. 2 is a side view showing an end portion of the draining material 7.
水切り材７は、上縁において略水平に突出された庇部７１と、中間部において略水平に突出された凸条部７２と、凸条部７２から略鉛直に垂下された垂下部７３とが、金属板の折り曲げ加工によって主に成形される。 The draining material 7 has a flange portion 71 that protrudes substantially horizontally at the upper edge, a protruding ridge portion 72 that protrudes substantially horizontally at the middle portion, and a hanging portion 73 that hangs substantially vertically from the protruding ridge portion 72. It is mainly formed by bending a metal plate.
側面視で上から凹凸となる庇部７１と凸条部７２との間の凹部は、端部において長方形の上端面部７４によって塞がれる。また、凸条部７２の下方は、端部において長方形の下端面部７５によって塞がれる。 A concave portion between the flange portion 71 and the convex strip portion 72 that is uneven from the top in a side view is closed by a rectangular upper end surface portion 74 at the end portion. Further, the lower part of the ridge 72 is closed by a rectangular lower end surface 75 at the end.
この水切り材７の庇部７１は、凸条部７２よりも突出量が大きくなっている。詳細には、庇部７１の先端縁は、凸条部７２の外壁面３１に対向させる壁対向面７２１よりも、差分Ｄ１分だけ外壁面３１側に突出されている。 The flange portion 71 of the draining material 7 has a larger protruding amount than the ridge portion 72. Specifically, the front end edge of the flange portion 71 protrudes toward the outer wall surface 31 by a difference D1 from the wall facing surface 721 that faces the outer wall surface 31 of the ridge 72.
一方、凸条部７２の壁対向面７２１に貼り付けられる水密材６の材厚Ｄ２は、差分Ｄ１よりも大きくなる。要するに水密材６は、最大でＤ２−Ｄ１の間隔分が圧縮される。 On the other hand, the thickness D2 of the watertight material 6 attached to the wall facing surface 721 of the ridge 72 becomes larger than the difference D1. In short, the watertight material 6 is compressed by the distance of D2-D1 at the maximum.
次に、本実施の形態の水切り構造１の構築方法について、図３−図７を参照しながら説明する。 Next, the construction method of the draining structure 1 of the present embodiment will be described with reference to FIGS.
まず、図３に示すように床２の上面２１に防水シート４を敷設する。そして、床２と壁３とが交差する隅角部においては、防水シート４の側縁部を外壁面３１に沿って立ち上げ、立上げ部４１とする。 First, the waterproof sheet 4 is laid on the upper surface 21 of the floor 2 as shown in FIG. And in the corner | angular part where the floor 2 and the wall 3 cross | intersect, the side edge part of the waterproof sheet 4 is raised along the outer wall surface 31, and it is set as the raising part 41. FIG.
この立上げ部４１によって、壁３の下部３２と床２の上面２１とが連続して防水シート４で覆われることになる。また、立上げ部４１に対しては、床２側から固定ネジ４２を壁３に向けてねじ込み、立ち上げられた状態を維持させる。 By this rising portion 41, the lower portion 32 of the wall 3 and the upper surface 21 of the floor 2 are continuously covered with the waterproof sheet 4. Moreover, the fixing screw 42 is screwed toward the wall 3 from the floor 2 side to the rising portion 41, and the raised state is maintained.
続いて図４に示すように、立上げ部４１の上縁４１１とその上方の外壁面３１とに跨るように、帯状の防水テープ５を貼り付ける。本実施の形態では、防水テープ５の下縁５２は立上げ部４１の高さ方向の中央付近に配置され、上縁５１と下縁５２との間の高さ方向の略中央は、立上げ部４１の上縁４１１辺りに配置される。 Subsequently, as shown in FIG. 4, the belt-shaped waterproof tape 5 is pasted so as to straddle the upper edge 411 of the rising portion 41 and the outer wall surface 31 above it. In the present embodiment, the lower edge 52 of the waterproof tape 5 is disposed near the center in the height direction of the rising portion 41, and the approximate center in the height direction between the upper edge 51 and the lower edge 52 is the rising edge. It is arranged around the upper edge 411 of the portion 41.
図５は、玄関などの開口部３３に隣接する壁３の下部３２が、防水シート４の立上げ部４１に覆われるとともに、防水テープ５によって立上げ部４１の上縁４１１が塞がれた状態を示している。 In FIG. 5, the lower portion 32 of the wall 3 adjacent to the opening 33 such as the entrance is covered with the rising portion 41 of the waterproof sheet 4, and the upper edge 411 of the rising portion 41 is blocked by the waterproof tape 5. Indicates the state.
さらに、図６に示すように、水切り材７によって立上げ部４１及び防水テープ５を覆う工程に移行する。この工程では、水切り材７の凸条部７２に貼り付けられた水密材６の高さ方向の略中央が、防水テープ５の上縁５１辺りに配置されるように水切り材７の取り付けを行う。 Furthermore, as shown in FIG. 6, the process proceeds to a step of covering the rising portion 41 and the waterproof tape 5 with the draining material 7. In this step, the draining material 7 is attached so that the approximate center in the height direction of the watertight material 6 affixed to the ridge 72 of the draining material 7 is disposed around the upper edge 51 of the waterproof tape 5. .
水切り材７の接合は、固定ネジ７６の先端にコーキング材７７を塗布して、凸条部７２に対してねじ込むことによって行われる。固定ネジ７６に塗布されたコーキング材７７は、水切り材７の貫通孔や防水テープ５の上縁５１付近に広がって、防水処理が施されたことになる。 The jointing of the draining material 7 is performed by applying a caulking material 77 to the tip of the fixing screw 76 and screwing it into the ridge 72. The caulking material 77 applied to the fixing screw 76 spreads in the vicinity of the through hole of the draining material 7 and the upper edge 51 of the waterproof tape 5 and is waterproofed.
ここで、凸条部７２は、床２側から見れば窪んでいる部分であるため、打ち込まれた固定ネジ７６の頭部が隠れた状態になり、目立たなくさせることができる。 Here, since the protrusion 72 is a portion that is depressed when viewed from the floor 2 side, the head of the fixed screw 76 that is driven in is hidden and can be made inconspicuous.
そして、凸条部７２を外壁面３１に対して押し付けると、水密材６が弾性変形して圧縮することになる。水密材６は、庇部７１の先端縁が外壁面３１に接触するまで、最大で圧縮変形させることができる。すなわち、材厚Ｄ２の水密材６をＤ１の厚さまで圧縮変形させることができる。 When the ridge 72 is pressed against the outer wall surface 31, the watertight member 6 is elastically deformed and compressed. The watertight material 6 can be compressed and deformed at the maximum until the tip edge of the flange 71 comes into contact with the outer wall surface 31. That is, the watertight material 6 having the material thickness D2 can be compressed and deformed to the thickness of D1.
図７は、以上のようにして水切り材７が取り付けられた開口部３３に隣接する壁３と床２の隅角部の水切り構造１を示している。開口部３３に面した水切り材７の端部は、上端面部７４及び下端面部７５で塞がれた状態になっている。 FIG. 7 shows the draining structure 1 at the corners of the wall 3 and the floor 2 adjacent to the opening 33 to which the draining material 7 is attached as described above. The end of the draining material 7 facing the opening 33 is closed by the upper end surface 74 and the lower end surface 75.
また、水切り材７の床２側に向いた正面は、帯状の見切り材としての機能を発揮している。この水切り材７の下縁は、図１に示すように、床２の上面２１を覆う防水シート４から離隔した位置に配置される。 Further, the front surface of the draining material 7 facing the floor 2 exhibits a function as a strip-shaped parting material. As shown in FIG. 1, the lower edge of the draining material 7 is disposed at a position separated from the waterproof sheet 4 that covers the upper surface 21 of the floor 2.
床２の上面２１に水切り材７の延伸方向の排水勾配が設けられている場合は、垂下部７３を排水勾配に合わせた台形状に成形することで、床２との離隔を一定にすることができる。 When the drainage gradient in the extending direction of the draining material 7 is provided on the upper surface 21 of the floor 2, the separation from the floor 2 is made constant by forming the drooping portion 73 into a trapezoidal shape that matches the drainage gradient. Can do.
次に、本実施の形態の水切り構造１、及びそれが設けられた建物並びに水切り材７の作用について説明する。 Next, the action of the draining structure 1 of the present embodiment, the building provided with the draining structure, and the draining material 7 will be described.
このように構成された本実施の形態の水切り構造１は、床２に敷設された防水シート４の立上げ部４１の上縁４１１周辺に防水テープ５が配置され、その防水テープ５は水切り材７との間に圧縮された状態で介在される水密材６によって外壁面３１に押し付けられる。 In the draining structure 1 of the present embodiment configured as described above, the waterproof tape 5 is disposed around the upper edge 411 of the rising portion 41 of the waterproof sheet 4 laid on the floor 2, and the waterproof tape 5 is a draining material. 7 is pressed against the outer wall surface 31 by a watertight material 6 interposed in a compressed state.
このため、防水シート４の上縁４１１を確実に外壁面３１に密着させることができ、防水性能の高い水切り構造１とすることができる。特に、意匠性を高める目的などで外壁面３１に凹凸がある場合であっても、防水シート４の上縁４１１を確実に外壁面３１に密着させることができる。 For this reason, the upper edge 411 of the waterproof sheet 4 can be made to contact | adhere to the outer wall surface 31 reliably, and it can be set as the draining structure 1 with high waterproof performance. In particular, the upper edge 411 of the waterproof sheet 4 can be reliably adhered to the outer wall surface 31 even when the outer wall surface 31 is uneven for the purpose of improving the design.
また、床２の上面２１に敷設された防水シート４が連続して壁３の下部３２を覆う立上げ部４１となるので、降水量が多くなって床２に水が溜まって水位が上昇する場合でも、防水性を確保することができる。 Moreover, since the waterproof sheet 4 laid on the upper surface 21 of the floor 2 continuously forms the rising portion 41 that covers the lower portion 32 of the wall 3, the amount of precipitation increases and water accumulates on the floor 2 and the water level rises. Even in the case, waterproofness can be ensured.
さらに、水切り材７に設けられた水密材６が弾性材であれば、水切り材７を外壁面３１に向けて押し当てるだけで、圧縮変形した水密材６の弾性力によって防水テープ５を外壁面３１に圧着させることができる。 Further, if the watertight material 6 provided on the water draining material 7 is an elastic material, the waterproof tape 5 is attached to the outer wall surface by the elastic force of the watertight material 6 that has been compressed and deformed simply by pressing the water draining material 7 against the outer wall surface 31. 31 can be pressure-bonded.
要するに凹凸面のある外壁面３１に防水テープ５を貼り付けても、凸部が密着するだけで凹部が隙間として残ってしまうが、水密材６によって防水テープ５を外側から外壁面３１に向けて押し付けることで、変形した防水テープ５が凹部を埋め、隙間がなくなる。この結果、防水シート４の上縁４１１の防水性能を向上させることができる。 In short, even if the waterproof tape 5 is attached to the outer wall surface 31 with the uneven surface, the concave portion remains as a gap only by the close contact of the convex portion. By pressing, the deformed waterproof tape 5 fills the concave portion and the gap is eliminated. As a result, the waterproof performance of the upper edge 411 of the waterproof sheet 4 can be improved.
また、水切り材７の上縁が外壁面３１に向けて突出された庇部７１に形成されていれば、外壁面３１を伝って流れ落ちた水滴を、すみやかに床２側に排出させることができる。 In addition, if the upper edge of the draining material 7 is formed on the flange 71 protruding toward the outer wall surface 31, water drops that have flowed down along the outer wall surface 31 can be quickly discharged to the floor 2 side. .
さらに、水切り材７の中間部に外壁面３１に向けて突出された凸条部７２が形成されていれば、凸条部７２によって防水テープ５を外壁面３１側に構造的に押し付けることができる。 Furthermore, if the protruding strip portion 72 protruding toward the outer wall surface 31 is formed at the intermediate portion of the draining material 7, the waterproof tape 5 can be structurally pressed against the outer wall surface 31 side by the protruding strip portion 72. .
また、水切り材７の庇部７１を凸条部７２よりも突出量が大きくなるようにするとともに、凸条部７２に水密材６を設けることによって、水密材６を圧縮させた状態での外壁面３１と庇部７１の先端縁との隙間を小さくすることができる。 In addition, the protrusion 71 of the draining material 7 has a protruding amount larger than that of the ridge 72, and the watertight material 6 is provided on the ridge 72 so that the watertight material 6 is compressed outside. A gap between the wall surface 31 and the leading edge of the flange portion 71 can be reduced.
そして、防水テープ５と水切り材７とによって構築される水切り構造１は、コーキング材７７を多用する湿式の防水構造に比べて簡単な作業で構築することができる。すなわち、コーキング材７７は固定ネジ７６の先端に塗布するだけなので、使用量を大幅に削減できるうえに、現場作業の負荷も低減することができる。 And the draining structure 1 constructed by the waterproof tape 5 and the draining material 7 can be constructed by a simple operation as compared with a wet waterproof structure using a large amount of the caulking material 77. In other words, since the caulking material 77 is only applied to the tip of the fixing screw 76, the amount of use can be greatly reduced, and the load on site work can be reduced.
以上、図面を参照して、本発明の実施の形態を詳述してきたが、具体的な構成は、この実施の形態に限らず、本発明の要旨を逸脱しない程度の設計的変更は、本発明に含まれる。 The embodiment of the present invention has been described in detail above with reference to the drawings. However, the specific configuration is not limited to this embodiment, and design changes that do not depart from the gist of the present invention are not limited to this embodiment. Included in the invention.
例えば、前記実施の形態では、防水テープ５と水切り材７との間に水密材６を介在させる構成について説明したが、これに限定されるものではなく、圧縮された状態で弾性材を介在させることができれば、防水テープ５を変形させて外壁面３１に密着させることができる。 For example, in the said embodiment, although the structure which interposes the watertight material 6 between the waterproofing tape 5 and the draining material 7 was demonstrated, it is not limited to this, An elastic material is interposed in the compressed state If possible, the waterproof tape 5 can be deformed and brought into close contact with the outer wall surface 31.
また、前記実施の形態では、防水材として防水テープ５を例に説明したが、これに限定されるものではなく、コーキング材７７を防水材として塗布し、硬化前などの変形性能がある状態で弾性材によって圧着させることで、凹凸面のある外壁面３１に密着させることができる。 Moreover, in the said embodiment, although the waterproof tape 5 was demonstrated to the example as a waterproofing material, it is not limited to this, In the state which has apply | coated the caulking material 77 as a waterproofing material and has deformation performance before hardening etc. By crimping with an elastic material, the outer wall surface 31 having an uneven surface can be brought into close contact.
