Description

本発明は、太陽電池モジュール、太陽熱温水器、空気調和機の室外機等の設備を建物の屋根上に設置するための設備固定装置に関する。   The present invention relates to an equipment fixing device for installing equipment such as a solar cell module, a solar water heater, and an outdoor unit of an air conditioner on a roof of a building.

太陽電池モジュール、太陽熱温水器、空気調和機の室外機等の設備を建物の屋根上に設置する場合、これらの設備を固定する固定部は、設備の重量、設置する地域の風圧、地震などに耐えうる強度を確保する必要がある。これらの設備を固定するには、予め、設備を固定するための固定金具(設備固定装置)を屋根上に固定し、その固定装置上に設備を固定する方法が一般的である。   When installing equipment such as solar cell modules, solar water heaters, and outdoor units of air conditioners on the roof of a building, the fixed part that fixes these equipment is used for the weight of the equipment, wind pressure in the area where it is installed, and earthquakes. It is necessary to ensure the strength to withstand. In order to fix these facilities, a method of fixing a fixture (equipment fixing device) for fixing the facility on the roof in advance and fixing the facility on the fixing device is generally used.

固定金具は、十分な固定強度を確保するために、屋根の野地板を介して垂木など屋根の構造体に、木ネジ、釘、ボルト・ナット等により固定される。しかしながら、通常、垂木が木材である場合、所定の間隔で垂木が配置されているため、垂木の位置に合わせて設備の固定位置が制約されるという問題がある。   In order to secure a sufficient fixing strength, the fixing bracket is fixed to a roof structure such as a rafter through a roof base plate with wood screws, nails, bolts / nuts, and the like. However, in general, when the rafters are wood, the rafters are arranged at a predetermined interval, so that there is a problem that the fixed position of the facility is restricted according to the position of the rafters.

また、垂木が金属の場合は、板厚が1〜3mm程度と薄板であることが多いため、ネジ等による固定では十分な強度が確保できない場合や、垂木の形状が複雑な場合もあるため、垂木へのネジ固定自体が困難であるという問題がある。   In addition, when the rafter is metal, the plate thickness is often a thin plate of about 1 to 3 mm, so that sufficient strength cannot be secured by fixing with screws or the like, and the rafter shape may be complicated, There is a problem that it is difficult to fix the screw to the rafter itself.

また、屋根材が金属である場合、金属屋根材の接合部であるハゼ部が垂木の上に位置していて、固定金具が垂木に取付けられないという問題がある。空気調和機の室外機等、比較的設置面積が小さい設備であれば、固定金具の個数が少ないため、設置位置を調整して設置することが可能であるが、太陽電池モジュールのように、屋根の広い面積に設置するような設備の場合、固定金具の個数が多く、設置位置を調整して設置することは困難である。   In addition, when the roofing material is a metal, there is a problem that the goby portion, which is a joint portion of the metal roofing material, is located on the rafter and the fixing bracket cannot be attached to the rafter. Equipment that has a relatively small installation area, such as an outdoor unit of an air conditioner, can be installed by adjusting the installation position because the number of fixing brackets is small. In the case of equipment installed in a wide area, the number of fixing brackets is large, and it is difficult to install by adjusting the installation position.

また、固定金具を垂木に固定せずに、屋根全面に敷設されている野地板に固定すれば、垂木の材質、形状等の制約もなく、設備の固定位置の自由度は高くなるが、野地板の厚さは通常9〜12mm程度のため、十分な強度が確保できないという問題がある。   In addition, if the fixing bracket is not fixed to the rafters, but fixed to a field plate laid on the entire roof surface, there is no restriction on the material and shape of the rafters, and the degree of freedom in fixing the equipment will be high. Since the thickness of the base plate is usually about 9 to 12 mm, there is a problem that sufficient strength cannot be secured.

このような問題を解決するために、例えば特許文献1には、野地板に形成されたボルト孔にボルトを貫通させ、ボルトに取り付けられた座金(ワンサイド座金と大座金)で野地板を挟み込んで、取付強度と防水性を確保する設備固定装置が開示されている。   In order to solve such a problem, for example, in Patent Document 1, a bolt is passed through a bolt hole formed in a base plate, and the base plate is sandwiched between washers (one side washer and a large washer) attached to the bolt. Thus, an equipment fixing device that secures mounting strength and waterproofness is disclosed.

特開平8−312075号公報JP-A-8-312075

しかしながら、上記特許文献1に記載された設備固定装置では、野地板に対して室内側に設けられるワンサイド座金が非対称形状であり、野地板との接触が片あたりとなる。そのため、野地板の挟み込みにて十分な取付強度が得られず、また強度バラツキが大きくなってしまうという問題があった。また、野地板に形成したボルト孔に比べ、ボルト軸の直径が小さくなるため、設備固定装置にガタツキが発生しやすく、強度不足になる場合があるという問題もあった。   However, in the equipment fixing device described in Patent Document 1, the one-side washer provided on the indoor side with respect to the base plate has an asymmetric shape, and the contact with the base plate is per one piece. Therefore, there has been a problem that sufficient mounting strength cannot be obtained by sandwiching the base plate, and the strength variation becomes large. In addition, since the diameter of the bolt shaft is smaller than that of the bolt hole formed in the base plate, there is a problem that the equipment fixing device is likely to rattle and the strength may be insufficient.

本発明は、上記に鑑みてなされたものであって、建物の屋根上に設置する設備を、野地板等のような、垂木以外の建物の構造体に固定し、十分な固定強度を確保しつつ、設備の設置位置の自由度を向上させることのできる設備固定装置を得ることを目的とする。   The present invention has been made in view of the above, and the facility installed on the roof of the building is fixed to a building structure other than rafters, such as field boards, to ensure sufficient fixing strength. On the other hand, an object of the present invention is to obtain an equipment fixing device capable of improving the degree of freedom of the installation position of equipment.

上述した課題を解決し、目的を達成するために、本発明は、長手方向に貫通孔が形成された筒状形状を呈する筒部と、筒部の長手方向に沿った一端側に設けられて、筒部の外周から外側に張り出す張出部と、筒部の他端側から挿入されて、筒部よりも長く形成された軸部と、筒部の内径よりも大きな外径に形成された頭部とを有するボルトと、筒部に挿入された状態のボルトの軸部に取り付けられたナットと、を備え、筒部には、長手方向に沿って延びるように形成された複数の開口が形成されていることを特徴とする。   In order to solve the above-described problems and achieve the object, the present invention is provided on a cylindrical portion having a cylindrical shape in which a through hole is formed in the longitudinal direction, and on one end side along the longitudinal direction of the cylindrical portion. An overhanging portion projecting outward from the outer periphery of the tubular portion, a shaft portion inserted from the other end side of the tubular portion and formed longer than the tubular portion, and an outer diameter larger than the inner diameter of the tubular portion. A plurality of openings formed so as to extend along the longitudinal direction, and a bolt attached to a shaft portion of the bolt inserted into the cylinder portion. Is formed.

本発明によれば、建物の屋根上に設置する設備を、例えば野地板等、垂木以外の構造体建物の構造体に固定し、十分な固定強度を確保するとともに、高い防水性を確保でき、設備の設置位置の自由度を向上させることのできる設備固定装置が得られるという効果を奏する。   According to the present invention, the equipment to be installed on the roof of the building is fixed to the structure of the structure building other than the rafter, such as a field plate, etc., and sufficient securing strength can be secured, and high waterproofness can be secured, There exists an effect that the installation fixing device which can improve the freedom degree of the installation position of an installation is obtained.

図2−1は、本発明の実施の形態1にかかる設備固定装置1の概略構成を示す側面図である。図2−2は、図2−1に示すA−A線に沿った矢視図である。図2−1および図2−2に示すように、設備固定装置1は、筒部10、支持部(張出部)12、ボルト13、防水部14、座金15、ナット16を備える。   FIG. 2-1 is a side view illustrating a schematic configuration of the equipment fixing device 1 according to the first exemplary embodiment of the present invention. FIG. 2-2 is an arrow view along the line AA shown in FIG. As illustrated in FIGS. 2A and 2B, the equipment fixing device 1 includes a tube portion 10, a support portion (overhang portion) 12, a bolt 13, a waterproof portion 14, a washer 15, and a nut 16.

図3−1は、筒部10の概略構成を示す側面図である。図3−2は、図3−1に示すB−B線に沿った矢視図である。筒部10は、長手方向に貫通孔10aが形成された筒状形状を呈している。筒部10の長手方向に沿った一端側には、筒部10の外周よりも外側に張り出す支持部12が設けられている。   FIG. 3A is a side view illustrating a schematic configuration of the cylindrical portion 10. FIG. 3-2 is an arrow view along the line BB shown in FIG. 3-1. The cylinder part 10 is exhibiting the cylindrical shape in which the through-hole 10a was formed in the longitudinal direction. On one end side along the longitudinal direction of the tube portion 10, a support portion 12 that protrudes outward from the outer periphery of the tube portion 10 is provided.

図3−2に示すように、支持部12は円筒形状を呈しており、筒部10の外径103よりも張出部の外径121のほうが大きくなっている。筒部10の材質は、金属もしくは樹脂などであるが、十分な取付強度を確保するためには金属であることが好ましい。   As shown in FIG. 3B, the support portion 12 has a cylindrical shape, and the outer diameter 121 of the overhang portion is larger than the outer diameter 103 of the tubular portion 10. The material of the cylindrical portion 10 is metal or resin, but is preferably metal in order to ensure sufficient mounting strength.

支持部12の材質は金属や樹脂、また防水性を有するブチルなどのパッキンである。なお、支持部12と筒部10とは、強固に接着され、容易には剥がれない構造となっている。なお、支持部12と筒部10とが同じ材質で構成される場合には、支持部12と筒部10とが一体成型されていても構わない。   The material of the support part 12 is metal, resin, or packing such as butyl having waterproofness. In addition, the support part 12 and the cylinder part 10 are firmly bonded, and have a structure that is not easily peeled off. In addition, when the support part 12 and the cylinder part 10 are comprised with the same material, the support part 12 and the cylinder part 10 may be integrally molded.

筒部10の側面には、長手方向に沿って延びるように複数の開口10bが形成されている。筒部10の側面において、開口10bと支持部12との間には所定の間隔が設けられている(以下、開口10bと支持部12との間の領域を面部102ともいう)。この所定の間隔は、設備固定装置1の取付対象となる屋根構造の野地板4の厚みと略同じ間隔であることが望ましい。   A plurality of openings 10b are formed on the side surface of the cylindrical portion 10 so as to extend along the longitudinal direction. A predetermined interval is provided between the opening 10b and the support portion 12 on the side surface of the cylindrical portion 10 (hereinafter, a region between the opening 10b and the support portion 12 is also referred to as a surface portion 102). The predetermined interval is preferably substantially the same as the thickness of the roof base plate 4 to which the equipment fixing device 1 is attached.

図3−3は、他の例としての筒部10の概略構成を示す側面図である。図3−3に示すように、開口10bと支持部12との間に外ねじ10cが形成されていてもよい。外ねじ10cのねじ山を含めた外径104は、筒部10の外径103よりも大きくなる。   FIG. 3C is a side view illustrating a schematic configuration of the cylindrical portion 10 as another example. As illustrated in FIG. 3C, an external screw 10 c may be formed between the opening 10 b and the support portion 12. The outer diameter 104 including the thread of the outer screw 10 c is larger than the outer diameter 103 of the cylindrical portion 10.

また、開口10bの形状は、筒部10の長手方向に沿って延びる形状であればよく、図3−1に示すように略長方形形状を呈していてもよいし、図3−3に示すように略ひし形形状を呈していてもよい。また、楕円形状であってもよい。   Moreover, the shape of the opening 10b should just be a shape extended along the longitudinal direction of the cylinder part 10, and may show the substantially rectangular shape as shown to FIGS. 3-1, and as shown to FIGS. 3-3. May have a substantially rhombus shape. Moreover, an elliptical shape may be sufficient.

図4は、ボルト13の概略構成を示す側面図である。ボルト13は、頭部13aと軸部13bを有する。頭部13aの外径111は、筒部10の貫通孔10aの内径110よりも大きく形成されている。ボルト13は、筒部10の他端側から貫通孔10aに挿入される。軸部13bの長さは、筒部10の長さよりも長くなっており、筒部10の一端側から軸部13bの先端が露出する。筒部10の一端側から露出した軸部13bの先端には、防水部14、座金15がはめ込まれ、さらにナット16がねじ込まれる。   FIG. 4 is a side view showing a schematic configuration of the bolt 13. The bolt 13 has a head portion 13a and a shaft portion 13b. The outer diameter 111 of the head portion 13 a is formed larger than the inner diameter 110 of the through hole 10 a of the cylindrical portion 10. The bolt 13 is inserted into the through hole 10 a from the other end side of the cylindrical portion 10. The length of the shaft portion 13 b is longer than the length of the tube portion 10, and the tip of the shaft portion 13 b is exposed from one end side of the tube portion 10. A waterproof part 14 and a washer 15 are fitted at the tip of the shaft part 13b exposed from one end side of the cylindrical part 10, and a nut 16 is further screwed.

次に、設備固定装置1を屋根構造に固定する手順について説明する。図5は、設備固定装置1が屋根構造に仮固定された状態を示す横断面図である。なお、図5では、屋根構造を断面図として示し、設備固定装置1を側面図として示している。まず、屋根構造に対して、屋根材5、野地板4、および防水層6を貫通する下孔7を形成し、筒部10の他端側から設備固定装置1を下孔7に挿入する。   Next, a procedure for fixing the equipment fixing device 1 to the roof structure will be described. FIG. 5 is a cross-sectional view showing a state in which the equipment fixing device 1 is temporarily fixed to the roof structure. In addition, in FIG. 5, the roof structure is shown as sectional drawing, and the installation fixing device 1 is shown as a side view. First, a lower hole 7 that penetrates the roof material 5, the field plate 4, and the waterproof layer 6 is formed in the roof structure, and the equipment fixing device 1 is inserted into the lower hole 7 from the other end side of the cylindrical portion 10.

なお、図1で示した屋根構造では、屋根材5が金属である場合を例に挙げているが、スレートやアスファルトシングルなどの屋根材であってもよいし、瓦を取り外した後のように屋根材が無い場合でもよい。   In the roof structure shown in FIG. 1, the roof material 5 is exemplified as a metal, but it may be a roof material such as a slate or asphalt single, or after the roof tile is removed. There may be no roofing material.

下孔7の直径701は、支持部12の外径121よりも小さくなっているため、支持部12が引っ掛かり、設備固定装置1が反対側に抜け落ちるのを防ぐことができる。なお、図3−1で例示したように筒部10の面部102に外ねじ10cが形成されていない場合には、下孔7の直径701を、筒部10の外径103と略同じかやや大きくするのが好ましい。また、図3−3で例示したように筒部10の面部102に外ねじ10cが形成されている場合には、下孔7の直径701を、筒部10の外径103と略同じかやや小さくするのが好ましい。   Since the diameter 701 of the lower hole 7 is smaller than the outer diameter 121 of the support portion 12, the support portion 12 can be prevented from being caught and the equipment fixing device 1 from falling off to the opposite side. As illustrated in FIG. 3A, when the external thread 10 c is not formed on the surface portion 102 of the cylindrical portion 10, the diameter 701 of the lower hole 7 is substantially the same as the outer diameter 103 of the cylindrical portion 10. It is preferable to enlarge it. Further, as illustrated in FIG. 3C, when the external thread 10 c is formed on the surface portion 102 of the cylindrical portion 10, the diameter 701 of the lower hole 7 is substantially the same as the outer diameter 103 of the cylindrical portion 10. It is preferable to make it smaller.

面部102に外ねじ10cが形成されている場合には、野地板4に対して筒部10がタッピングしながら挿入されるため、筒部10が野地板4により密着し、ボルト13の屋根構造に対する垂直度の向上、および水平方向の固定強度と防水性の向上の効果が期待できる。また、面部102の外周部にはシーリング材が具備されていてもよい。この場合も野地板4との密着性が向上する。   When the external thread 10 c is formed on the surface portion 102, the tube portion 10 is inserted into the field plate 4 while tapping, so that the tube portion 10 is in close contact with the field plate 4 and the roof structure of the bolt 13 is The effect of improving the verticality and improving the horizontal fixing strength and waterproofness can be expected. Further, a sealing material may be provided on the outer peripheral portion of the surface portion 102. Also in this case, the adhesion with the base plate 4 is improved.

次に、ナット16を締結方向に締め付ける。図6−1は、ナット16を途中まで締め付けた状態の設備固定装置1を示す横断面図である。なお、図6−1では、屋根構造を断面図として示し、設備固定装置1を側面図として示している。ナット16を締結方向に締め付けることで、図6−1に示すように、ボルト13の頭部13aが筒部10の他端を押し上げ、筒部10の開口10bに挟まれた領域が、その中央付近で外側方向に変形する。   Next, the nut 16 is tightened in the fastening direction. FIG. 6A is a cross-sectional view showing the equipment fixing device 1 in a state where the nut 16 is tightened halfway. In addition, in FIG. 6-1, the roof structure is shown as sectional drawing, and the installation fixing device 1 is shown as a side view. By tightening the nut 16 in the fastening direction, as shown in FIG. 6A, the region where the head 13a of the bolt 13 pushes up the other end of the tube 10 and is sandwiched between the openings 10b of the tube 10 is the center. Deforms outward in the vicinity.

図6−2は、ナット16をさらに締め付けた状態の設備固定装置1を示す横断面図である。図6−3は、図6−2に示すC−C線に沿った矢視図である。なお、図6−2では、屋根構造を断面図として示し、設備固定装置1を側面図として示している。図6−1に示す状態からさらにナット16を締め付けると、図6−2に示すように、筒部10の変形した部分が野地板4に接触し、座金15と筒部10とで野地板4を挟み込む形となる。   FIG. 6B is a cross-sectional view showing the equipment fixing device 1 in a state where the nut 16 is further tightened. FIG. 6-3 is an arrow view along the line CC shown in FIG. 6-2. In addition, in FIG. 6-2, the roof structure is shown as sectional drawing, and the installation fixing device 1 is shown as a side view. When the nut 16 is further tightened from the state shown in FIG. 6A, as shown in FIG. 6B, the deformed portion of the cylindrical portion 10 comes into contact with the base plate 4, and the base plate 4 is formed by the washer 15 and the cylindrical portion 10. It will be in the form of sandwiching.

ナット16の締結によって、防水部14は座金15と野地板4との間で押し潰され、屋根材5や野地板4、また各部材の隙間を埋めるように密着するため、高い防水性を確保することができる。また、開口10bの数と位置を調整することで、筒部10の変形した部分を対称形に野地板4に接触させることができる。これにより、設備固定装置1に風圧荷重などが加えられた場合でも、片あたりとなるのを抑えて、バラツキが少ない十分な強度を確保することができる。   By fastening the nut 16, the waterproof part 14 is crushed between the washer 15 and the base plate 4, and is in close contact with the roof material 5, the base plate 4, and the gaps between the respective members, ensuring high waterproofness. can do. Moreover, the deformed part of the cylinder part 10 can be made to contact the field board 4 symmetrically by adjusting the number and position of the opening 10b. Thereby, even when a wind pressure load or the like is applied to the equipment fixing device 1, it is possible to suppress the contact between the pieces and secure a sufficient strength with little variation.

例えば、複数形成される開口10bの開口幅を略等しくし、開口10b同士の間隔を略等しくすることで、筒部の変形した部分を対称形に野地板4に接触させることができる。また、開口10bを少なくとも3箇所以上形成すれば、筒部10の変形した部分と野地板4との接触箇所が3箇所以上になるので、設備固定装置1をより安定的に屋根構造に固定することができる。   For example, the deformed portion of the cylindrical portion can be brought into contact with the base plate 4 symmetrically by making the opening widths of the plurality of openings 10b substantially equal and the intervals between the openings 10b substantially equal. Further, if at least three openings 10b are formed, there are three or more contact points between the deformed portion of the cylindrical portion 10 and the field plate 4, so that the equipment fixing device 1 is more stably fixed to the roof structure. be able to.

次に、屋根上に設備を固定する設備固定金具が、設備固定装置1によって屋根構造に取り付けられた様子を図面で示す。図7−1は、設備固定金具20が設備固定装置1によって屋根構造に取り付けられた様子を示す断面図である。図7−1に示すように、設備固定金具20は、設備固定装置1を取り付ける際に、防水部14の下に共締めされてもよい。この場合は、設備固定金具20の裏面にブチル等の防水層201を追加することで、より防水性を高めることもできる。   Next, a state in which the equipment fixing bracket for fixing the equipment on the roof is attached to the roof structure by the equipment fixing device 1 is shown in the drawings. FIG. 7A is a cross-sectional view illustrating a state in which the equipment fixing bracket 20 is attached to the roof structure by the equipment fixing device 1. As illustrated in FIG. 7A, the equipment fixing bracket 20 may be fastened together under the waterproof portion 14 when the equipment fixing device 1 is attached. In this case, the waterproof property can be further improved by adding a waterproof layer 201 such as butyl to the back surface of the equipment fixing bracket 20.

図7−2は、設備固定金具11が設備固定装置1によって屋根構造に取り付けられた様子を示す断面図である。図7−2に示すように、設備固定装置1を取り付けた上にさらに別構造としてナット17等をボルト13にはめ込んで、設備固定金具11を屋根構造に取り付けてもよい。   FIG. 7-2 is a cross-sectional view illustrating a state in which the equipment fixing bracket 11 is attached to the roof structure by the equipment fixing device 1. As shown in FIG. 7-2, the equipment fixing bracket 11 may be attached to the roof structure by fitting a nut 17 or the like into the bolt 13 as a separate structure after the equipment fixing device 1 is attached.

以上説明したように、設備固定装置1は、野地板4を筒部10の変形した部分と座金15等で挟んで固定するので、垂木2を介さずにより強固に屋根上に設備を固定することができる。ここで、図1−2に示すように、ハゼ部3と重なってしまった垂木2には、ハゼ部3が邪魔になってしまい、垂木2を介して固定される固定装置を用いることが難しい場合がある。そのため、垂木2を介して設備を固定する場合には、設備の配置が制限されてしまう場合がある。一方、本実施の形態にかかる設備固定装置1であれば、垂木2を介さずに設備を固定することができるので、設備の設置位置の自由度の向上を図ることができる。   As described above, since the equipment fixing device 1 fixes the field plate 4 by sandwiching the deformed portion of the cylindrical portion 10 with the washer 15 or the like, the equipment is firmly fixed on the roof without the rafter 2. Can do. Here, as shown in FIG. 1-2, it is difficult to use a fixing device that is fixed via the rafter 2 because the goby 3 becomes an obstacle to the rafter 2 that has overlapped with the goby 3. There is a case. For this reason, when the equipment is fixed via the rafter 2, the arrangement of the equipment may be limited. On the other hand, in the equipment fixing device 1 according to the present embodiment, the equipment can be fixed without using the rafter 2, so that the degree of freedom of the installation position of the equipment can be improved.

図8は、筒部10の変形例を示す側面図である。図9−1は、ボルト13の変形例を示す側面図である。図9−2は、図9−1に示すD−D線に沿った矢視図である。筒部10の面部102には複数の孔105が開孔されている。また、ボルト13の中心には貫通孔131が、側面には複数の孔132が開孔されている。この場合、設備固定装置1を取り付けた後に、貫通孔131に液状やゲル状等のシーリング材を注入することで、孔105,132を通して、野地板4の断面および裏面にもシーリングが回り込み、より防水性を高めることが可能となる。   FIG. 8 is a side view showing a modified example of the cylindrical portion 10. FIG. 9A is a side view illustrating a modified example of the bolt 13. FIG. 9-2 is an arrow view along the line DD shown in FIG. A plurality of holes 105 are formed in the surface portion 102 of the cylindrical portion 10. A through hole 131 is formed at the center of the bolt 13 and a plurality of holes 132 are formed at the side surface. In this case, after attaching the equipment fixing device 1, by injecting a sealing material such as liquid or gel into the through hole 131, the sealing wraps around the cross section and the back surface of the base plate 4 through the holes 105 and 132. It becomes possible to improve waterproofness.

以上のように、本発明にかかる設備固定装置は、太陽電池モジュール、太陽熱温水器、空気調和機の室外機等の設備を建物の屋根上に設置するための装置として有用である。   As described above, the equipment fixing device according to the present invention is useful as a device for installing equipment such as a solar cell module, a solar water heater, and an outdoor unit of an air conditioner on the roof of a building.
