従来から、建物の屋根や外壁に配置される防水鋼板等の面材と面材との間の目地部を止水する防水構造体に設けられ、該目地部の水密性を図るために適用される防水材が知られている。   Conventionally, it is provided in a waterproof structure that stops the joint between the face material such as a waterproof steel plate arranged on the roof or outer wall of the building and the face material, and is applied to achieve water tightness of the joint. Waterproofing materials are known.

例えば、特許文献１は、下方が開放された長尺略円筒形の本体と、その本体の下端部を外側に折り曲げた折り曲げ部とからなり、該折り曲げ部が隣接した屋根面材の対向する端縁部と端縁部とに嵌着される目地カバー部材の内部に取着される、ブチル系ゴム等で形成された長尺かまぼこ形の防水材を開示している（例えば、特許文献１等参照）。
特開２００５−２３５９０号公報 For example, Patent Document 1 is composed of a long, substantially cylindrical main body that is open at the bottom, and a bent portion that is bent outward at the lower end of the main body, and the opposite end of the roof surface material adjacent to the bent portion.

JP 2005-23590 A

しかしながら、このような目地カバー部材の内部に設けられる従来の防水材にあっては、以下の点を改善することが求められていた。   However, in the conventional waterproof material provided inside such a joint cover member, it has been required to improve the following points.

（１）上記特許文献１に記載の防水材において該防水材が長尺かまぼこの形状に形成されているように、従来技術の防水材は、例えば手で折り曲げようとしても容易に変形しにくい構成となっている。そのため、このような防水材を目地カバー部材の折り曲げ部からその内部へと取り付ける際、防水材を斜めから挿入したり、折り曲げ部の弾性力に抗して力ずくで防水材を内部に押し込めたりする必要があり、防水材の取り付けに手間がかかっていた。   (1) In the waterproof material described in the above-mentioned Patent Document 1, the waterproof material according to the prior art has a configuration that is not easily deformed even if it is bent by hand, for example, so that the waterproof material is formed in a long kamaboko shape. It has become. Therefore, when attaching such a waterproof material from the bent portion of the joint cover member to the inside of the joint cover member, the waterproof material is inserted obliquely, or the waterproof material is pushed into the inside by force against the elastic force of the bent portion. It was necessary and it took time to install the waterproof material.

（２）従来では、目地カバー部材の内面に当接する防水材の部分の形状が、該目地カバー部材の内面形状に必ずしも合致していなかった。そのため、例えば目地カバー部材を屋根面材の端縁部と端縁部とに嵌着する際、その内部に取り付けた防水材が、所定の位置からずれたり外れたりしてしまう場合があった。また、防水材が所定の位置からずれたり外れたりしてしまう虞を回避するため、防水材を目地カバー部材の内面に接着する必要があった。   (2) Conventionally, the shape of the portion of the waterproof material that contacts the inner surface of the joint cover member does not necessarily match the inner surface shape of the joint cover member. Therefore, for example, when the joint cover member is fitted to the end edge portion and the end edge portion of the roof surface material, the waterproof material attached to the inside may be displaced or deviated from a predetermined position. Moreover, in order to avoid a possibility that a waterproof material will shift | deviate from a predetermined position or remove | deviate, it was necessary to adhere | attach a waterproof material to the inner surface of a joint cover member.

（３）従来では粘着材としてのブチル系ゴム等が、防水材本体の端部にまで設けられていた。そのため、該防水材を目地カバー部材の折り曲げ部からその内部へと挿入する際に、粘着材の端部が該折り曲げ部に当たって粘着してしまう場合があり、防水材を目地カバー部材の内部に挿入するのに手間を要していた。   (3) Conventionally, butyl rubber or the like as an adhesive material has been provided up to the end of the waterproof body. For this reason, when the waterproof material is inserted into the joint cover member from the folded portion thereof, the end of the adhesive material may come into contact with the folded portion and stick, and the waterproof material is inserted into the joint cover member. It took time and effort.

また、粘着材が防水材本体の端部にまで設けられている場合、その粘着材の表面を接触から保護するリケイ紙も該端部にまで設けられているので、防水材を目地カバー部材の内部に取り付けた後、このリケイ紙を剥すために指先を目地カバー部材の内部の奥にまで入れる必要があった。そのため、リケイ紙を剥しにくいという不都合があった。   Further, when the adhesive material is provided up to the end of the waterproof material main body, the waterproof material that protects the surface of the adhesive material from contact is also provided up to the end, so the waterproof material is attached to the joint cover member. After being attached inside, it was necessary to put the fingertips into the interior of the joint cover member in order to peel off this waste paper. For this reason, there is an inconvenience that it is difficult to remove the waste paper.

本発明は上記の点に鑑みてなされたものであり、その目的は、容易に目地カバー部材の内部に挿入・取り付けが可能で、取り付け後に所定の位置から外れにくく、リケイ紙を剥しやすい目地カバー部材の防水材を提供することにある。   The present invention has been made in view of the above points. The purpose of the present invention is to provide a joint cover that can be easily inserted into and attached to the joint cover member, and is unlikely to be removed from a predetermined position after the attachment, making it easy to peel off the waste paper. It is in providing the waterproof material of a member.

There is no need to put it in the interior of the member, and it is possible to provide a waterproof material that is easy to peel off the waste paper.

以下、本発明を図１乃至図５に示した実施例に沿って詳細に説明する。   Hereinafter, the present invention will be described in detail with reference to the embodiments shown in FIGS.

図１は、本発明に係る防水材１０の断面図である。図２は、本発明に係る防水材１０を目地カバー部材２０の内部に取り付けた状態を示す断面図である。   FIG. 1 is a cross-sectional view of a waterproof material 10 according to the present invention. FIG. 2 is a cross-sectional view showing a state in which the waterproof material 10 according to the present invention is attached to the inside of the joint cover member 20.

図１に示すように、この防水材１０は、ＥＰＤＭ（エチレン−プロピレン−ジエンゴム）等の発泡体１２と、ブチル系ゴム等の粘着材１４とを積層させて構成されている。この発泡体１２と粘着材１４とは、図２に示すように、防水材１０が目地カバー部材２０の内部に取り付けられた際、防水材１０の発泡体１２側が目地カバー部材２０の内面２０ａに当接するように、防水材１０の上部が発泡体１２、防水材１０の下部であってその発泡体１２の下が粘着材１４という態様で積層されている。   As shown in FIG. 1, this waterproof material 10 is configured by laminating a foam 12 such as EPDM (ethylene-propylene-diene rubber) and an adhesive material 14 such as butyl rubber. As shown in FIG. 2, when the waterproof material 10 is attached to the inside of the joint cover member 20, the foam 12 and the adhesive material 14 are disposed on the inner surface 20 a of the joint cover member 20. The waterproof material 10 is laminated in such a manner that the upper part of the waterproof material 10 is the foam 12 and the lower part of the waterproof material 10 and the lower part of the foam 12 is the adhesive material 14 so as to abut.

また、この防水材１０の粘着材１４の幅は、発泡体１２の幅よりも狭く構成されている。すなわち、図１に示すように、粘着材１４は発泡体１２と比較して短く形成されており、粘着材１４の端部１４ａと発泡体１２の端部１２ａとは、所定の距離を置いて互いに離間している。   Further, the width of the adhesive material 14 of the waterproof material 10 is configured to be narrower than the width of the foam 12. That is, as shown in FIG. 1, the adhesive material 14 is formed shorter than the foam 12, and the end 14 a of the adhesive 14 and the end 12 a of the foam 12 are spaced apart from each other by a predetermined distance. They are separated from each other.

この実施例では、これに限定されないが、例えば発泡体１２の幅は２８ｍｍであり、粘着材１４の幅はそれよりも狭い、例えば２５ｍｍである。その粘着材１４の表面１４ｂには、該表面１４ｂを接触から保護するリケイ紙が一様に張られている。   In this embodiment, although not limited to this, for example, the width of the foam 12 is 28 mm, and the width of the adhesive material 14 is narrower than that, for example, 25 mm. On the surface 14 b of the adhesive material 14, a silica paper that uniformly protects the surface 14 b from contact is stretched.

図１に示すように、この防水材１０の発泡体１２の上下両面中央部は、その発泡体１２の全長に渡って凹溝状に各々形成されており、この上下面の溝の凹部の底面近傍で最も狭くなった部分にくびれ部１６が構成されている。   As shown in FIG. 1, the center portions of the upper and lower surfaces of the foam 12 of the waterproof material 10 are each formed in a groove shape over the entire length of the foam 12. A constricted portion 16 is formed at the narrowest portion in the vicinity.

このため、くびれ部１６は、目地カバー部材２０の長手方向（図３における目地カバー部材２０の長手方向）に略全域に延設されている。   For this reason, the constricted part 16 is extended over substantially the whole area in the longitudinal direction of the joint cover member 20 (longitudinal direction of the joint cover member 20 in FIG. 3).

このくびれ部１６は、図２に示す矢印方向に防水材１０を目地カバー部材２０の内部に挿入する際、例えば防水材１０を、くびれ部１６を中心としてその防水材１０の両端を下方に向かって二つ折りに屈曲可能にしている。   When the waterproof material 10 is inserted into the joint cover member 20 in the direction of the arrow shown in FIG. 2, for example, the constricted portion 16 has the waterproof material 10 facing downward at both ends of the waterproof material 10 around the constricted portion 16. Can be bent in half.

そのため、図１に示す防水材１０の幅Ｈ２を、図４に示す防水材１０の幅Ｈ３となるように防水材１０を屈曲させて、後述する目地カバー部材２０の折り曲げ部２２、２２間の開口幅Ｈ１よりも狭くすることができるので、防水材１０を目地カバー部材２０の内部に容易に挿入することが可能となっている。   Therefore, the waterproofing material 10 is bent so that the width H2 of the waterproofing material 10 shown in FIG. 1 becomes the width H3 of the waterproofing material 10 shown in FIG. 4, and between the bent portions 22 and 22 of the joint cover member 20 described later. Since the opening width H1 can be made narrower, the waterproof material 10 can be easily inserted into the joint cover member 20.

また、防水材１０が目地カバー部材２０の内部に挿入されると、この屈曲された防水材１０の発泡体１２の復元力により、防水材１０の上部は目地カバー部材２０の内面２０ａに圧接して、防水材１０は目地カバー部材２０の内部に取り付けされる。   When the waterproof material 10 is inserted into the joint cover member 20, the upper portion of the waterproof material 10 is pressed against the inner surface 20 a of the joint cover member 20 by the restoring force of the foam 12 of the bent waterproof material 10. The waterproof material 10 is attached inside the joint cover member 20.

この防水材１０の上部の形状は、目地カバー部材２０の内面２０ａの形状と合致するように形成されている。図２に示すように、防水材１０の発泡体１２が目地カバー部材２０の内面２０ａに当接して取り付けられた際、その目地カバー部材２０の内面２０ａに当接する発泡体１２の部分が内面２０ａと一致して、この内面２０ａにより防水材１０の位置がガイドされるとともに固定されるように構成されている。   The shape of the upper portion of the waterproof material 10 is formed so as to match the shape of the inner surface 20 a of the joint cover member 20. As shown in FIG. 2, when the foam 12 of the waterproof material 10 is attached in contact with the inner surface 20a of the joint cover member 20, the portion of the foam 12 that contacts the inner surface 20a of the joint cover member 20 is the inner surface 20a. The position of the waterproof material 10 is guided and fixed by the inner surface 20a.

その目地カバー部材２０は、板厚約０．４ｍｍのステンレス鋼板、アルミメッキ鋼板、塩化ビニル樹脂被覆銅板等の金属板で構成され、図３に示すように下方が開放された長手方向略円筒形に形成されている。   The joint cover member 20 is made of a metal plate such as a stainless steel plate having a thickness of about 0.4 mm, an aluminum-plated steel plate, or a vinyl chloride resin-coated copper plate, and has a substantially cylindrical shape in the longitudinal direction with its lower portion opened as shown in FIG. Is formed.

該目地カバー部材２０の下端部両側には、外側に折り曲げられた折り曲げ部２２、２２が形成され、図４に示すように、この折り曲げ部２２、２２を以下に詳述する隣接した面材３０、３０の、互いに対向する端縁部３０ａと端縁部３０ａとの両端縁部にそれぞれ係合させることで、目地カバー部材２０が該両端縁部に嵌着される。   On both sides of the lower end portion of the joint cover member 20, bent portions 22 and 22 bent outward are formed. As shown in FIG. 4, the bent portions 22 and 22 are adjacent face materials 30 described in detail below. , 30 are engaged with both end edges of the end edge 30a and the end edge 30a facing each other, whereby the joint cover member 20 is fitted to the both end edges.

その図４に示すように、面材３０は、本実施例ではオリエンティド・ストランドボード（ＯＳＢ）や構造用合板等の野地板５０の上に配置された屋根の防水鋼板であり、目地カバー部材２０と同様、板厚約０．４ｍｍのステンレス鋼板、アルミメッキ鋼板、塩化ビニル樹脂被覆銅板等の金属板で構成されている。その野地板５０の上に配置された各々の面材３０の両端には、上述の端縁部３０ａが形成されている。   As shown in FIG. 4, the face material 30 is a roof waterproof steel plate arranged on a field plate 50 such as an oriented strand board (OSB) or a structural plywood in the present embodiment, and the joint cover member 20. In the same manner as above, it is made of a metal plate such as a stainless steel plate having a thickness of about 0.4 mm, an aluminized steel plate, or a vinyl chloride resin-coated copper plate. The above-mentioned edge portions 30a are formed at both ends of each face member 30 arranged on the base plate 50.

この端縁部３０ａは、平面状の面材３０に対して略直角に折り曲がった折り曲げ部３２と、この折り曲げ部３２の先端から各々の面材３０の内側に向けて折り曲げた折り曲げ部３４と、該折り曲げ部３４の先端からその面材３０の外側に向けて略斜め上方に折り曲げた折り曲げ部３６とを有して構成されている。   The edge portion 30a includes a bent portion 32 that is bent at a substantially right angle with respect to the planar face member 30, and a bent portion 34 that is bent from the tip of the bent portion 32 toward the inside of each face member 30. The bent portion 34 has a bent portion 36 that is bent substantially obliquely upward from the front end of the bent portion 34 toward the outside of the face member 30.

図３に示すように、隣接した面材３０、３０の互いに対向する端縁部３０ａと端縁部３０ａとの両端縁部間には、該隣接する面材３０、３０を共に連結する結合部材としてのアンカークリップ４０が長手方向に沿って挿入される。   As shown in FIG. 3, a coupling member that connects the adjacent face members 30, 30 together between the opposite end edges 30 a of the adjacent face members 30, 30 and the both end edges of the end edge 30 a. The anchor clip 40 is inserted along the longitudinal direction.

このアンカークリップ４０も上記の目地カバー部材２０および面材３０と同様、板厚約０．４ｍｍのステンレス鋼板、アルミメッキ鋼板、塩化ビニル樹脂被覆銅板等の金属板で構成され、上方が開口された断面略コ字形に形成されている。そのアンカークリップ４０の該上方の両側先端部は、それぞれ外側に折り曲げられて、折り曲げ部４２、４２を構成している。   This anchor clip 40 is also composed of a metal plate such as a stainless steel plate having a thickness of about 0.4 mm, an aluminized steel plate, a vinyl chloride resin-coated copper plate, etc., as in the case of the joint cover member 20 and the face material 30, and has an upper opening. It is formed in a substantially U-shaped cross section. The tip portions on both upper sides of the anchor clip 40 are bent outward to form bent portions 42 and 42, respectively.

このアンカークリップ４０の折り曲げ部４２、４２が、図５に示すように両方の端縁部３０ａ、３０ａの折り曲げ部３４、３４にそれぞれ係合するように、アンカークリップ４０を隣接する面材３０、３０の対向する端縁部３０ａと端縁部３０ａとの両端縁部間に長手方向に挿入することで、隣接する面材３０、３０は共に連結される。   As shown in FIG. 5, the anchor clip 40 is attached to the adjacent face material 30, so that the bent portions 42, 42 of the anchor clip 40 engage with the bent portions 34, 34 of both end edges 30a, 30a, respectively. The adjacent face members 30 and 30 are connected together by inserting them in the longitudinal direction between the opposite edge portions of the 30 opposite edge portions 30a and 30a.

また、アンカークリップ４０の底部にはビス孔４４が形成されている。このビス孔４４にビス４６を挿入し、該ビス４６を野地板５０に貫通させ、たる木６０にねじ込むことで、アンカークリップ４０が野地板５０に圧着されて隣接する面材３０、３０が野地板５０に対して固定される。   A screw hole 44 is formed at the bottom of the anchor clip 40. The screw 46 is inserted into the screw hole 44, the screw 46 is passed through the base plate 50, and screwed into the rafter 60, whereby the anchor clip 40 is pressure-bonded to the base plate 50 and the adjacent face members 30, 30 are connected to the base plate. 50 fixed.

そのアンカークリップ４０を用いて隣接する面材３０、３０を連結・固定した後、図５に示すように上記目地カバー部材２０を該両端縁部に対して嵌着させると、面材３０の端縁部３０ａを構成する折り曲げ部３４の先端、およびその折り曲げ部３４と折り曲げ部３２との間に、目地カバー部材２０の折り曲げ部２２がその弾性力によりそれぞれ係合し、且つ該折り曲げ部２２の先端が面材３０の表面に当接するように構成されている。   After connecting and fixing the adjacent face members 30 and 30 using the anchor clip 40, when the joint cover member 20 is fitted to both edge portions as shown in FIG. The bent portion 22 of the joint cover member 20 is engaged by the elastic force between the distal end of the bent portion 34 constituting the edge portion 30a and the bent portion 34 and the bent portion 32, and the bent portion 22 The tip is configured to contact the surface of the face material 30.

また、折り曲げ部２２を端縁部３０ａの折り曲げ部３４と折り曲げ部３２との間に係合させて目地カバー部材２０を両端縁部に嵌着させると、図５に示すように、その目地カバー部材２０の内部に取り付けられた防水材１０は該目地カバー部材２０によって押圧されるとともに、その防水材１０の粘着材１４の表面１４ｂは、隣接する面材３０、３０の対向する端縁部３０ａ、３０ａの折り曲げ部３６、３６に強固に密着・接着するようになっている。   Further, when the bent portion 22 is engaged between the bent portion 34 and the bent portion 32 of the end edge portion 30a and the joint cover member 20 is fitted to both end edge portions, as shown in FIG. The waterproof material 10 attached to the inside of the member 20 is pressed by the joint cover member 20, and the surface 14 b of the adhesive material 14 of the waterproof material 10 is opposite edge portions 30 a of the adjacent face materials 30, 30. , 30a are tightly adhered and adhered to the bent portions 36, 36.

これにより、隣接する面材３０、３０の対向する端縁部３０ａと３０ａとの両端縁部間と、該隣接する面材３０、３０を共に連結させるアンカークリップ４０とが目地カバー部２０により覆われ、且つ防水材１０により該両端縁部間とアンカークリップ４０とが水密となるように構成されている。   As a result, the joint cover portion 20 covers the gap between the opposite end edges 30a and 30a of the adjacent face members 30, 30 and the anchor clip 40 that connects the adjacent face members 30, 30 together. In addition, the waterproof material 10 is configured so that the edge clip and the anchor clip 40 are watertight.

次に、本実施例の作用効果について説明する。   Next, the function and effect of this embodiment will be described.

まず、防水材１０を目地カバー部材２０の内部に挿入して取り付ける。この時、防水材１０の発泡体１２の上下面中央部にはくびれ部１６が形成されているので、図２に示すように矢印方向に防水材１０を挿入する際に防水材１０が目地カバー部材２０の折り曲げ部２２、２２に当接しても、防水材１０は容易に折曲変形する。そのため、防水材１０を折り曲げ部２２、２２の弾性力に抗して力ずくで内部に押し込める必要がない。   First, the waterproof material 10 is inserted into the joint cover member 20 and attached. At this time, since the constricted portion 16 is formed at the center of the upper and lower surfaces of the foam 12 of the waterproof material 10, the waterproof material 10 covers the joint cover when the waterproof material 10 is inserted in the direction of the arrow as shown in FIG. 2. Even if it contacts the bent portions 22 and 22 of the member 20, the waterproof material 10 is easily bent and deformed. For this reason, it is not necessary to force the waterproof material 10 into the inside by forcibly resisting the elastic force of the bent portions 22 and 22.

また、手で防水材１０をあらかじめ折曲変形させてから目地カバー部材２０の内部に挿入することもできるので、防水材１０を目地カバー部材２０の内部に容易に取り付けることができる。   In addition, since the waterproof material 10 can be bent and deformed in advance by hand, it can be inserted into the joint cover member 20, so that the waterproof material 10 can be easily attached to the interior of the joint cover member 20.

その上、防水材１０の粘着材１４の幅は、発泡体１２の幅よりも狭く構成されている。そのため、防水材１０を目地カバー部材２０の内部に挿入する際、防水材１０の発泡体１２の端部１２ａが目地カバー部材２０の折り曲げ部２２に当接しても粘着材１４の端部１４ａは折り曲げ部２２には当接しないので、粘着材１４の端部１４ａが目地カバー部材２０の折り曲げ部２２に当たって粘着してしまうことがない。したがって、防水材１０を目地カバー部材２０の内部に容易に挿入することができる。   In addition, the width of the adhesive material 14 of the waterproof material 10 is configured to be narrower than the width of the foam 12. Therefore, when the waterproof material 10 is inserted into the joint cover member 20, even if the end 12 a of the foam 12 of the waterproof material 10 comes into contact with the bent portion 22 of the joint cover member 20, the end 14 a of the adhesive material 14 remains Since it does not contact the bent portion 22, the end portion 14 a of the adhesive material 14 does not hit the bent portion 22 of the joint cover member 20 and adhere to it. Therefore, the waterproof material 10 can be easily inserted into the joint cover member 20.

また、この防水材１０の上部の形状は、目地カバー部材２０の内面２０ａの形状と合致するように形成されているので、防水材１０の発泡体１２が目地カバー部材２０の内面２０ａに当接して取り付けられた際、その目地カバー部材２０の内面２０ａに当接する発泡体１２の部分が内面２０ａと一致する。これにより、該内面２０ａによって防水材１０の位置がガイドされて固定されることになる。   Further, since the shape of the upper portion of the waterproof material 10 is formed so as to match the shape of the inner surface 20 a of the joint cover member 20, the foam 12 of the waterproof material 10 contacts the inner surface 20 a of the joint cover member 20. The portion of the foam 12 that contacts the inner surface 20a of the joint cover member 20 coincides with the inner surface 20a. Thereby, the position of the waterproof material 10 is guided and fixed by the inner surface 20a.

そのため、防水材１０を目地カバー部材２０の内面２０ａに取り付けた後、特に接着等をしなくても防水材１０は所定の位置からずれたり外れたりすることが防止される。   Therefore, after the waterproof material 10 is attached to the inner surface 20a of the joint cover member 20, the waterproof material 10 can be prevented from being displaced or detached from a predetermined position without particularly bonding.

さらに、防水材１０を目地カバー部材２０の内面２０ａに取り付けた後、図２に示すように防水材１０の粘着材１４の幅は発泡体１２の幅よりも狭く構成されているので、粘着材１４の端部１４ａと目地カバー部材２０の内面２０ａとの間には隙間Ｓが発生する。   Further, after the waterproof material 10 is attached to the inner surface 20a of the joint cover member 20, the width of the adhesive material 14 of the waterproof material 10 is narrower than the width of the foam 12 as shown in FIG. A gap S is generated between the end portion 14 a of 14 and the inner surface 20 a of the joint cover member 20.

この粘着材１４の表面１４ｂを保護するリケイ紙も、粘着材１４と同様、発泡体１２の端部１２ａまで設けられていないので、その隙間Ｓからリケイ紙を剥すことができる。   Similarly to the adhesive material 14, the silica paper that protects the surface 14 b of the adhesive material 14 is not provided up to the end 12 a of the foam 12, and therefore the silica paper can be peeled from the gap S.

そのため、目地カバー部材２０の内面２０ａにまで延びた粘着材のリケイ紙を剥すために、内面２０ａと粘着材の端部とが当接する目地カバー部材２０の内部の奥の部分にまで指先を入れる必要があった従来の場合と比較して、容易にリケイ紙を剥すことができる。   Therefore, in order to peel off the adhesive paper extending to the inner surface 20a of the joint cover member 20, the fingertip is inserted into the inner part of the joint cover member 20 where the inner surface 20a contacts the end of the adhesive material. Compared to the conventional case where it is necessary, the silica paper can be easily peeled off.

次に、図３に示すように隣接する面材３０、３０の対向する端縁部３０ａと端縁部３０ａとの両端縁部間にアンカークリップ４０を長手方向に挿入して隣接する面材３０、３０を連結し、ビス４６をアンカークリップ４０のビス孔４４に挿通してたる木６０にねじ込み、面材３０、３０を野地板５０に固着する。   Next, as shown in FIG. 3, the adjacent clip 30 is inserted by inserting the anchor clip 40 in the longitudinal direction between the opposite end edges 30 a of the adjacent face materials 30, 30. , 30 are connected, and the screw 46 is screwed into a tree 60 which is inserted through the screw hole 44 of the anchor clip 40 to fix the face materials 30, 30 to the base plate 50.

そして、目地カバー部材２０の折り曲げ部２２を、面材３０の端縁部３０ａの折り曲げ部３４の先端および該折り曲げ部３４と折り曲げ部３２との間にそれぞれ係合させて、図５に示すように、目地カバー部材２０を隣接する面材３０、３０の対向する端縁部３０ａと３０ａとの両端縁部間にその弾性力で嵌着させる。   Then, the bent portion 22 of the joint cover member 20 is engaged with the tip of the bent portion 34 of the edge 30a of the face member 30 and between the bent portion 34 and the bent portion 32, as shown in FIG. Next, the joint cover member 20 is fitted by the elastic force between both end edges of the facing edge portions 30a and 30a of the adjacent face members 30 and 30.

この目地カバー部材２０の折り曲げ部２２は、その先端が面材３０の表面に当接する態様で両端縁部間を覆うので、降雨の他、面材３０上の積雪による凍結や融解による水分の浸入を防ぐことができる。   The bent portion 22 of the joint cover member 20 covers between the edge portions in such a manner that the front end of the bent portion 22 abuts against the surface of the face member 30, so that in addition to rainfall, moisture enters due to freezing or melting due to snow on the face member 30. Can be prevented.

その目地カバー部材２０の内部に取り付けられた防水材１０の粘着材１４の表面１４ｂは、目地カバー部材２０が両端縁部間に嵌着されると、該目地カバー部材２０によって押圧されて隣接する面材３０、３０の対向する端縁部３０ａ、３０ａの折り曲げ部３６、３６に圧着・接着される。これにより、該両端縁部とその間に係合したアンカークリップ４０との水密性が確保される。   The surface 14b of the adhesive material 14 of the waterproof material 10 attached to the inside of the joint cover member 20 is pressed and adjoined by the joint cover member 20 when the joint cover member 20 is fitted between both edge portions. The face materials 30 and 30 are pressure-bonded and bonded to the bent portions 36 and 36 of the opposite edge portions 30a and 30a. Thereby, the water-tightness of this both-ends edge part and the anchor clip 40 engaged between them is ensured.

なお、上述の実施形態は本発明の好適な実施の一例ではあるが、これに限定されるものではなく、本発明の要旨を逸脱しない範囲において種々変形実施可能であるのは勿論である。   The above-described embodiment is an example of a preferred embodiment of the present invention. However, the present invention is not limited to this, and various modifications can be made without departing from the scope of the present invention.

例えば、本実施例では面材３０は建物の屋根に配置される防水鋼板であるが、バルコニー床、外壁、開口廻り等、その他の建物の外部に設けられる面材であってもよく、このような面材３０と面材３０との目地部を止水する目地カバー部材２０に本発明に係る防水材１０を適用してもよい。   For example, in the present embodiment, the face material 30 is a waterproof steel plate disposed on the roof of a building, but may be a surface material provided outside the building such as a balcony floor, an outer wall, around an opening, and the like. The waterproof material 10 according to the present invention may be applied to the joint cover member 20 that stops the joint between the face material 30 and the face material 30.
