Description

本発明は、雪止め支持金具、及び、雪止め構造を伴った屋根の防水構造に関する。   The present invention relates to a snow stopper support and a waterproof structure for a roof with a snow stopper structure.

降雪が多い地域では、屋根に積もった雪が屋根から落下するのを防止するために、雪止めバーが屋根に設置されている。雪止めバーは、雪止め支持金具を介して屋根に固定される。横葺き屋根に適用される従来の雪止め支持金具は、屋根板の接続部における折り返し部の下に差し込まれて固定されたり、折り返し部を掴んだりして屋根に固定されている（例えば特許文献１、２参照）。また、縦葺き屋根に適用される従来の雪止め支持金具は、屋根板の接続部における立上り部を掴んで屋根に固定されている（例えば特許文献３参照）。また、瓦屋根に適用される従来の雪止め支持金具は、瓦の端に引っ掛けることで屋根に固定されている（例えば特許文献４参照）。   In areas with heavy snowfall, snowstop bars are installed on the roof to prevent snow on the roof from falling off the roof. The snow stopper bar is fixed to the roof via a snow stopper support. A conventional snow stopper supporting metal applied to a side-roofed roof is fixed by being inserted under a folded portion in a connecting portion of a shingle, or fixed to the roof by gripping the folded portion (for example, Patent Documents) 1, 2). In addition, a conventional snow stopper support applied to a vertically-roofed roof is fixed to the roof by grasping a rising portion in a connection portion of a roof plate (for example, see Patent Document 3). Further, a conventional snow stopper supporting metal applied to a tiled roof is fixed to the roof by being hooked on an edge of the tile (for example, see Patent Document 4).

屋根は、長期間の使用により老朽化して雨漏り等の問題が生じる場合がある。そこで、屋根の防水性を回復させるために、屋根の表面全体を防水部材で覆うことが行われている。
ところが、上述したような従来の雪止め支持金具は、屋根材（屋根板や瓦）を利用して固定するため、屋根の表面を防水部材で覆ってしまうと設置できなくなる。 Roofs may become aging due to long-term use and cause problems such as rain leakage. Therefore, in order to restore the waterproofness of the roof, the entire surface of the roof is covered with a waterproof member.
However, the above-mentioned conventional snow stopper mounting bracket is fixed using a roof material (roof or tile), and thus cannot be installed if the surface of the roof is covered with a waterproof member.

そこで、本発明は、屋根の表面を防水部材で覆っていても設置が可能であって、屋根材の接続部や端部がなくても屋根に固定することができる雪止め支持金具と、この雪止め支持金具を用いた、雪止め構造を伴った屋根の防水構造を提供することを目的とする。   Therefore, the present invention provides a snow stopper support that can be installed even if the surface of the roof is covered with a waterproof member, and that can be fixed to the roof without connecting parts or ends of the roof material. An object of the present invention is to provide a waterproof structure of a roof with a snow stopper structure using a snow stopper support.

以下、本発明の実施の形態について図面を参照しつつ説明する。
図１は、本実施形態の雪止め構造を伴った屋根１００の防水構造１（以下、雪止め有り防水構造１という）を示している。まず、雪止め有り防水構造１が適用される屋根１００の構造について説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a waterproof structure 1 (hereinafter, referred to as a waterproof structure 1 with a snow stopper) of a roof 100 with a snow stopper structure of the present embodiment. First, the structure of the roof 100 to which the waterproof structure 1 with snow stopper is applied will be described.

本実施形態の屋根１００は、縦葺き屋根の一種である瓦棒葺き屋根で構成されている。縦葺き屋根とは、屋根の傾斜方向に長い複数の屋根板１０２を設けた屋根である。瓦棒葺き屋根とは、屋根板１０２同士の連結部分に、屋根の傾斜に沿って延びる瓦棒部１０１が設けられた屋根である。屋根１００の表面のうち、瓦棒部１０１の表面以外の部分は、同一平面状に形成されている。つまり、屋根１００の表面には、平坦状の部分が形成されている。   The roof 100 according to the present embodiment is configured with a tiled roof, which is a type of vertical roof. The vertical roof is a roof provided with a plurality of shingles 102 long in the inclination direction of the roof. The tiled roof is a roof provided with a tile rod portion 101 extending along a slope of the roof at a connection portion between the roof plates 102. The portion of the surface of the roof 100 other than the surface of the tile rod portion 101 is formed in the same plane. That is, a flat portion is formed on the surface of the roof 100.

屋根１００は、複数の屋根板１０２と、屋根板１０２の下方に配置された屋根下地板１０３を有する。屋根板１０２と屋根下地板１０３とを合わせたものが、屋根材に相当する。屋根下地板１０３の下方には、水平方向に延びる複数の垂木１０４（本発明の屋根基部）が屋根１００の傾斜方向に配列されている。この垂木１０４によって屋根材（屋根板１０２および屋根下地板１０３）は支えられている。なお、以下の説明において垂木１０４の延在方向と平行な方向を屋根幅方向という。屋根下地板１０３は、木製または金属製である。屋根板１０２は、金属板である。本実施形態の垂木１０４は、Ｃ形鋼であるが、Ｈ型鋼などＣ形鋼以外の鋼材であってもよく、木製の角材であってもよい。   The roof 100 has a plurality of shingles 102 and a roof slab 103 arranged below the shingles 102. The combination of the roof plate 102 and the roof base plate 103 corresponds to a roof material. Below the roof base plate 103, a plurality of rafters 104 (the roof base of the present invention) extending in the horizontal direction are arranged in the inclination direction of the roof 100. Roofing materials (roofing plate 102 and roof base plate 103) are supported by the rafters 104. In the following description, a direction parallel to the direction in which the rafters 104 extend is referred to as a roof width direction. The roof base plate 103 is made of wood or metal. The roof plate 102 is a metal plate. The rafter 104 of the present embodiment is a C-shaped steel, but may be a steel material other than a C-shaped steel such as an H-shaped steel, or may be a wooden bar.

なお、雪止め有り防水構造１が適用される屋根１００は、瓦棒葺き屋根に限定されるものではない。瓦棒葺き屋根以外の縦葺き屋根に適用してもよい。また、複数の屋根板が屋根の傾斜に沿って配列される横葺き屋根に適用してもよい。また、後述する雪止め支持金具３のベース部１０より大きい面積の平坦状の部分を確保できれば、折り板葺き屋根や、平板瓦の瓦屋根に適用してもよい。   The roof 100 to which the waterproof structure 1 with snow stopper is applied is not limited to a tiled roof. It may be applied to a vertical roof other than a tiled roof. Further, the present invention may be applied to a horizontal roof in which a plurality of shingles are arranged along the slope of the roof. Further, as long as a flat portion having an area larger than the base portion 10 of the snow stopper supporting metal member 3 to be described later can be secured, the present invention may be applied to a folded-plate roof or a flat-roof tile roof.

図２に示すように、雪止め有り防水構造１は、防水部材２、雪止め支持金具３、固定ビス４、シール部材５、雪止めバー６、固定部材７を備えている。   As shown in FIG. 2, the waterproof structure 1 with snow stopper includes a waterproof member 2, a snow stopper support fitting 3, a fixing screw 4, a sealing member 5, a snow stopper bar 6, and a fixing member 7.

The waterproof member 2 is a flexible sheet formed of rubber or resin. The rubber constituting the waterproof member 2 includes, for example, EPDM, IIR or a blend thereof, and the resin includes, for example, polyvinyl chloride, polyethylene and the like. The waterproof member 2 is attached to the surface of the roof panel 102. The waterproof member 2 itself may have an adhesive layer, or may be attached with an adhesive.

雪止め支持金具３は、雪止めバー６を屋根１００に固定するためのものである。雪止め支持金具３は、防水部材２の上に配置される。雪止め支持金具３は、屋根１００の表面のうち瓦棒部１０１を除く部分、即ち、屋根１００の表面のうち平坦状の部分に、防水部材２を介して配置されている。   The snow stopper support 3 is for fixing the snow stopper bar 6 to the roof 100. The snow stopper support 3 is disposed on the waterproof member 2. The snow stopper 3 is disposed on a portion of the surface of the roof 100 other than the tile rod portion 101, that is, on a flat portion of the surface of the roof 100 via the waterproof member 2.

雪止め支持金具３は、ベース部１０と突出部１１を有する。図３に示すように、ベース部１０は、矩形状の板状に形成されている。なお、図２は、図３のＡ−Ａ線の位置で切断した断面図を示している。ベース部１０は、防水部材２の表面に配置される。ベース部１０には、４つのビス挿通孔１０ａが形成されている。突出部１１は、ベース部１０から上方（屋根１００の表面と反対側）に向かって突出している。突出部１１は、ベース部１０に接続された円柱部１２と、円柱部１２の上面の中央部に接続されたボルト部１３とを有する。円柱部１２の径は、ボルト部１３の径よりも大きい。円柱部１２の上下方向長さは、瓦棒部１０１の上下方向長さよりも長い。ボルト部１３の外周面には、ねじ溝が形成されている。   The snow stopper support 3 has a base 10 and a protrusion 11. As shown in FIG. 3, the base portion 10 is formed in a rectangular plate shape. FIG. 2 is a sectional view taken along the line AA in FIG. The base 10 is disposed on the surface of the waterproof member 2. The base portion 10 is formed with four screw insertion holes 10a. The protruding portion 11 protrudes upward (the side opposite to the surface of the roof 100) from the base portion 10. The protruding part 11 has a column part 12 connected to the base part 10 and a bolt part 13 connected to the center part of the upper surface of the column part 12. The diameter of the cylindrical portion 12 is larger than the diameter of the bolt portion 13. The vertical length of the cylindrical portion 12 is longer than the vertical length of the tile bar portion 101. A screw groove is formed on the outer peripheral surface of the bolt portion 13.

固定ビス４は、雪止め支持金具３を垂木１０４に固定する。固定ビス４は、雪止め支持金具３のビス挿通孔１０ａに上方から挿通され、防水部材２および屋根材（屋根板１０２および屋根下地板１０３）を貫通して垂木１０４にねじ込まれる。固定ビス４は、先端がドリル状に形成された、いわゆるセルフドリルビスである。固定ビス４は、下穴を開けずに垂木１０４を貫通できる。また、固定ビス４を垂木１０４にねじ込むことで、垂木１０４にネジ山が形成されるので、垂木１０４に固定ビス４をネジ締め固定できる。なお、垂木１０４が木製の場合には、固定ビス４はセルフドリルビスでなくてもよい。   The fixing screw 4 fixes the snow stopper support 3 to the rafter 104. The fixing screw 4 is inserted from above into the screw insertion hole 10 a of the snow stopper support fitting 3, and is screwed into the rafter 104 through the waterproof member 2 and the roof material (the roof plate 102 and the roof base plate 103). The fixing screw 4 is a so-called self-drilling screw whose tip is formed in a drill shape. The fixing screw 4 can penetrate the rafter 104 without making a pilot hole. Further, by screwing the fixing screw 4 into the rafter 104, a thread is formed in the rafter 104, so that the fixing screw 4 can be screwed and fixed to the rafter 104. When the rafter 104 is made of wood, the fixing screw 4 need not be a self-drilling screw.

シール部材５は、雪止め支持金具３のベース部１０と、防水部材２のベース部１０の周囲部を覆うように配置される。雪止め支持金具３の突出部１１は、シール部材５を貫通する。シール部材５は、第１シール材１４と、第１シール材１４の上に重ねられた第２シール材１５で構成されている。第１シール材１４は、雪止め支持金具３のベース部１０の上面と、防水部材２の上面に貼り付けられている。第２シール材１５は、第１シール材１４よりも大きく、第１シール材１４全体を覆っている。第２シール材１５は、第１シール材１４の上面と、防水部材２の上面に貼り付けられている。第１シール材１４および第２シール材１５は、非加硫ゴムからなり、自己粘着性によって貼り付けられている。接着剤を併用してより強固に固定してもよい。   The seal member 5 is arranged so as to cover the base 10 of the snow stopper 3 and the peripheral portion of the base 10 of the waterproof member 2. The projection 11 of the snow stopper 3 penetrates the seal member 5. The seal member 5 includes a first seal member 14 and a second seal member 15 stacked on the first seal member 14. The first seal member 14 is attached to the upper surface of the base portion 10 of the snow stopper support 3 and the upper surface of the waterproof member 2. The second sealant 15 is larger than the first sealant 14 and covers the entire first sealant 14. The second sealing member 15 is attached to the upper surface of the first sealing member 14 and the upper surface of the waterproof member 2. The first sealing material 14 and the second sealing material 15 are made of non-vulcanized rubber, and are adhered by self-adhesion. An adhesive may be used in combination to fix more firmly.

防水部材２の表面、および、シール部材５の表面（第２シール材１５の表面）は、外観性、耐候性、遮熱性等の向上のため塗装されている。   The surface of the waterproof member 2 and the surface of the seal member 5 (the surface of the second seal member 15) are painted for improving appearance, weather resistance, heat shielding and the like.

雪止めバー６は、屋根１００上の積雪を支えるためのものである。雪止めバー６は、複数の雪止め支持金具３によって屋根１００に固定されている。雪止めバー６は、屋根幅方向（水平方向）に沿って延びている。雪止めバー６の屋根幅方向の長さは、屋根１００の幅と同じであっても、それより短くてもよい。なお、図１では、雪止めバー６は屋根１００の１面に１本だけ設けられているが、２本以上設けられていてもよい。   The snow stopper bar 6 is for supporting snow on the roof 100. The snow stopper 6 is fixed to the roof 100 by a plurality of snow stoppers 3. The snow stopper 6 extends along the roof width direction (horizontal direction). The length of the snow stopper bar 6 in the roof width direction may be equal to or shorter than the width of the roof 100. In FIG. 1, only one snow stopper bar 6 is provided on one surface of the roof 100, but two or more snow stopper bars 6 may be provided.

雪止めバー６は、取付板部１６と雪止め板部１７とからなる断面Ｌ字状の金属板で構成されている。取付板部１６には、複数の貫通孔１６ａが形成されている。貫通孔１６ａの径は、ボルト部１３の径より大きく、円柱部１２の径よりも小さい。取付板部１６の貫通孔１６ａには、雪止め支持金具３のボルト部１３が挿通される。雪止めバー６の取付板部１６は、雪止め支持金具３の突出部１１の円柱部１２に支持される。   The snow stopper bar 6 is formed of a metal plate having an L-shaped cross section and including a mounting plate portion 16 and a snow stopper plate portion 17. The mounting plate 16 has a plurality of through holes 16a. The diameter of the through-hole 16 a is larger than the diameter of the bolt 13 and smaller than the diameter of the column 12. The bolt 13 of the snow stopper support 3 is inserted into the through hole 16 a of the mounting plate 16. The mounting plate 16 of the snow stopper bar 6 is supported by the column 12 of the protrusion 11 of the snow stopper support 3.

取付板部１６の貫通孔１６ａから突出するボルト部１３の先端部には、固定部材７が取り付けられる。固定部材７は、ナット１８と、平座金１９と、ばね座金２０を有する。雪止めバー６は、固定部材７によって雪止め支持金具３の突出部１１のボルト部１３に固定される。   The fixing member 7 is attached to the tip of the bolt 13 protruding from the through hole 16 a of the mounting plate 16. The fixing member 7 has a nut 18, a flat washer 19, and a spring washer 20. The snow stopper bar 6 is fixed to the bolt 13 of the protrusion 11 of the snow stopper support 3 by a fixing member 7.

次に、雪止め有り防水構造１の施工手順について説明する。   Next, a construction procedure of the waterproof structure 1 with snow stopper will be described.

まず、垂木１０４の位置を確認して、複数の雪止め支持金具３を設置する位置を決める。そして、屋根板１０２の表面全体を防水部材２で覆い、防水部材２を屋根板１０２の表面に貼り付ける。   First, the positions of the rafters 104 are confirmed, and the positions at which the plurality of snow stoppers 3 are installed are determined. Then, the entire surface of the roof plate 102 is covered with the waterproof member 2, and the waterproof member 2 is attached to the surface of the roof plate 102.

次に、複数の雪止め支持金具３を所定の位置に配置して、各雪止め支持金具３を固定ビス４によって垂木１０４に固定する。その後、第１シール材１４を雪止め支持金具３のベース部１０とその周囲に貼り付けてから、第２シール材１５を第１シール材１４の上から貼り付ける。   Next, the plurality of snow stoppers 3 are arranged at predetermined positions, and the respective snow stoppers 3 are fixed to the rafters 104 with fixing screws 4. After that, the first seal member 14 is attached to the base portion 10 of the snow stopper support fitting 3 and the periphery thereof, and then the second seal member 15 is attached from above the first seal member 14.

続いて、防水部材２の表面、および、シール部材５の表面（第２シール材１５の表面）を塗装する。その後、雪止めバー６を固定部材７によって雪止め支持金具３に固定する。   Subsequently, the surface of the waterproof member 2 and the surface of the sealing member 5 (the surface of the second sealing material 15) are painted. Thereafter, the snow stopper bar 6 is fixed to the snow stopper support fitting 3 by the fixing member 7.

なお、本実施形態の雪止め有り防水構造１は、屋根１００の新設時に同時に施工してもよく、既存の屋根１００に施工してもよい。   The waterproof structure 1 with snow stopper according to the present embodiment may be installed at the same time when the roof 100 is newly installed, or may be installed on the existing roof 100.

本実施形態の雪止め有り防水構造１では、雪止め支持金具３は、屋根１００の表面の平坦状の部分に防水部材２を介して配置されて、固定ビス４によって屋根１００基部に固定される。したがって、平坦状の部分を有する屋根であればどのような種類の屋根であっても雪止め支持金具３を設置することができ、屋根板１０２の接続部や端部を利用せずに雪止め支持金具３を屋根１００に固定することができる。また、雪止め支持金具３は、屋根板１０２の接続部や端部を利用せずに固定ビス４によって屋根１００に固定されるため、屋根１００の表面全体が防水部材２で覆われていても設置することができる。
さらに、雪止め支持金具３のベース部１０と防水部材２のベース部１０の周囲部は、シール部材５によって覆われるため、雪止め支持金具３を固定するために屋根材（屋根板１０２および屋根下地板１０３）に孔を開けても防水性を確保できる。 In the waterproof structure 1 with snow stopper according to the present embodiment, the snow stopper support fitting 3 is disposed on the flat portion of the surface of the roof 100 via the waterproof member 2 and is fixed to the base of the roof 100 by fixing screws 4. . Therefore, the snow stopper support 3 can be installed on any type of roof as long as the roof has a flat portion, and the snow stopper can be installed without using the connection portion or the end of the roof plate 102. The support fitting 3 can be fixed to the roof 100. Further, the snow stopper 3 is fixed to the roof 100 by the fixing screw 4 without using the connection portion or the end of the roof panel 102, so that the entire surface of the roof 100 is covered with the waterproof member 2. Can be installed.
Furthermore, since the periphery of the base portion 10 of the snow stopper support member 3 and the base portion 10 of the waterproof member 2 are covered with the seal member 5, the roof material (the roof plate 102 and the roof plate 102) is used to fix the snow stopper support member 3. Even if a hole is formed in the base plate 103), waterproofness can be ensured.

以上、本発明の好適な実施の形態について説明したが、本発明は上述の実施形態に限られるものではなく、特許請求の範囲に記載した限りにおいて様々な変更が可能である。   The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiment, and various modifications can be made as long as they are described in the claims.

上記実施形態では、固定部材７は、ナット１８と、平座金１９と、ばね座金２０を有するが、ナット１８以外の部品が異なっていても良い。   In the above embodiment, the fixing member 7 has the nut 18, the flat washer 19, and the spring washer 20, but components other than the nut 18 may be different.

上記実施形態では、雪止めバー６に形成された貫通孔１６ａに、突出部１１のボルト部１３を挿通して固定部材７で締結することで、雪止めバー６を雪止め支持金具３の突出部１１に固定しているが、雪止めバー６を雪止め支持金具３の突出部１１に固定する構造は上記に限定されない。
例えば、ボルト部１３を設ける代わりに、ベース部１０と平行で円柱部１２より面積が大きい板状部分を設け、この板状部分と雪止めバー６の取付板部１６とを重ね合わせた状態でその両端部を固定部材によって固定してもよい。 In the above-described embodiment, the bolt 13 of the protrusion 11 is inserted into the through hole 16 a formed in the snow stopper bar 6 and fastened by the fixing member 7, so that the snow stopper bar 6 projects from the snow stopper support 3. Although fixed to the portion 11, the structure for fixing the snow stopper bar 6 to the protruding portion 11 of the snow stopper support 3 is not limited to the above.
For example, instead of providing the bolt portion 13, a plate-shaped portion that is parallel to the base portion 10 and has a larger area than the columnar portion 12 is provided, and the plate-shaped portion and the mounting plate portion 16 of the snow stopper 6 are overlapped. Both ends may be fixed by a fixing member.

上記実施形態では、固定ビス４は、Ｃ形鋼である垂木１０４を貫通している。しかし、図４に示すように、固定ビス２０４は垂木１０４を貫通しなくてもよい。固定ビス２０４は、セルフドリルビスであって、上記実施形態の固定ビス４よりも短い。固定ビス２０４は、下穴を開けずに垂木１０４の上側部分（屋根材に接する部分）１０４ａを貫通できる。固定ビス２０４を垂木１０４の上側部分１０４ａにねじ込むことで、垂木１０４の上側部分１０４ａにネジ山が形成されるので、垂木１０４に固定ビス２０４をネジ締め固定できる。この構成によると、垂木１０４の下側部分に固定ビス２０４をねじ込まなくて済むので、作業性が向上する。また、上記実施形態に比べて、固定ビスが短いので、固定ビスの材料コストを低減できる。なお、図２および図４の垂木１０４はＣ形鋼である。垂木１０４がＣ形鋼以外の鋼材の場合、固定ビスは、図４と同様に垂木１０４の上側部分だけを貫通してもよく、上記実施形態と同様に垂木１０４全体を貫通してもよい。垂木１０４が木製の場合、固定ビスは垂木１０４の貫通してもよく、貫通しなくてもよい。   In the above embodiment, the fixing screw 4 penetrates the rafter 104 which is a C-shaped steel. However, as shown in FIG. 4, the fixing screw 204 does not have to penetrate the rafter 104. The fixing screw 204 is a self-drilling screw, and is shorter than the fixing screw 4 in the above embodiment. The fixing screw 204 can penetrate the upper part (the part in contact with the roofing material) 104a of the rafter 104 without making a pilot hole. By screwing the fixing screw 204 into the upper part 104 a of the rafter 104, a screw thread is formed in the upper part 104 a of the rafter 104, so that the fixing screw 204 can be screwed and fixed to the rafter 104. According to this configuration, since the fixing screw 204 does not need to be screwed into the lower part of the rafter 104, workability is improved. Further, since the fixing screw is shorter than in the above embodiment, the material cost of the fixing screw can be reduced. Note that the rafter 104 in FIGS. 2 and 4 is a C-shaped steel. When the rafter 104 is a steel material other than the C-shaped steel, the fixing screw may penetrate only the upper portion of the rafter 104 as in FIG. 4 or may penetrate the entire rafter 104 as in the above embodiment. When the rafter 104 is made of wood, the fixing screw may or may not penetrate the rafter 104.
