Description

本発明は、屋根上に搭載される太陽電池モジュール等の機器を支持するための装置及び方法であり、特に横葺き屋根の接合部に固着することにより屋根上に搭載される機器の架台を支持するための支持装置と、該支持装置を使用することにより実施される支持方法に関する。 The present invention is a device and a method for supporting a device such as a solar cell module mounted on a roof, and particularly supports a frame of the device mounted on the roof by being fixed to a joint of a horizontal roof. And the support method carried out by using the support device.

従来、屋根上に太陽電池モジュールを搭載するための装置が提案されている。その多くは、瓦屋根に関する技術であるが、太陽光エネルギーを活用するためには、瓦屋根に限らず、横葺き屋根に関しても強いニーズがある。 Conventionally, a device for mounting a solar cell module on a roof has been proposed. Most of them are technologies related to tiled roofs, but in order to utilize solar energy, there is a strong need not only for tiled roofs but also for horizontal roofs.

この点に関して、横葺き屋根の接合部に固着するように構成した支持装置が提案されている（特許文献１） In this regard, a support device configured to be fixed to a joint of a horizontal roof has been proposed (Patent Document 1).

特許第５６７５９１３号公報Japanese Patent No. 5675913

横葺き屋根の屋根材は、塗装された鋼板（以下「通常鋼板」という。）が一般的であるが、近年、塗装に加えて石粒等を付着することにより硬い表層を形成した鋼板（以下「硬層付き鋼板」という。）が提供され、遮音性・遮熱性・耐候性に優れるものとして好評を博している。通常鋼板は、折曲加工が容易であるため、平馳等の馳構造により接合部を構成することが容易であり、接合部を偏平状として全体高さを比較的低く形成することができる。 The roofing material for a horizontal roof is generally a painted steel plate (hereinafter referred to as "normal steel plate"), but in recent years, a steel plate having a hard surface layer formed by adhering stone grains or the like in addition to painting (hereinafter referred to as "normal steel plate"). "Steel sheet with hard layer") is provided and has been well received as having excellent sound insulation, heat insulation and weather resistance. Since ordinary steel sheets are easy to bend, it is easy to form a joint with a flat structure or the like, and the joint can be flattened to form a relatively low overall height.

これに対して、硬層付き鋼板は、折曲加工が容易でないため、偏平な馳構造を構成することが困難であり、接合部の全体高さが比較的高くなることが知られている。 On the other hand, it is known that a steel sheet with a hard layer is not easy to bend, so that it is difficult to form a flat steel structure, and the overall height of the joint is relatively high.

特許文献１により提案された従来の支持装置を図１８ないし図２１に示している。横葺屋根は、水平面Ｈに対して上流側Ｕの棟側から下流側Ｄの軒側に向けて角度θ１の下り勾配を有する屋根下地材１に屋根材２を敷設している。屋根材２は、上述の硬層付き鋼板により形成されている。 The conventional support device proposed by Patent Document 1 is shown in FIGS. 18 to 21. In the thatched roof, the roofing material 2 is laid on the roof base material 1 having a downward slope at an angle θ1 from the ridge side of the upstream side U to the eaves side of the downstream side D with respect to the horizontal plane H. The roofing material 2 is formed of the above-mentioned steel plate with a hard layer.

図１８の（Ａ）に拡大図を示すように、屋根材２は、上流に向かう端部に上向きに折曲された起立壁３と該起立壁３から上流方向に延びる平板壁４を形成し、下流に向かう端部に下向きに折曲された垂下壁５を形成している。これにより、下流側に敷設された屋根材２Ｄと上流側に敷設された屋根材２Ｕの相互に屋根接合部６を構成する As shown in the enlarged view in FIG. 18A, the roofing material 2 forms an upright wall 3 bent upward at an end facing upstream and a flat plate wall 4 extending upstream from the upright wall 3. , Forming a downwardly bent hanging wall 5 at the downstream end. As a result, the roofing material 2D laid on the downstream side and the roofing material 2U laid on the upstream side form a roof joint 6 with each other.

屋根接合部６は、下流側の屋根材２Ｄの平板壁４を屋根用ビス７で屋根下地材１に固着し、上流側の屋根材２Ｕの垂下壁５を前記起立壁３に覆い被せ、接合用ビス８でビス止めすることにより形成される。 In the roof joint portion 6, the flat plate wall 4 of the roof material 2D on the downstream side is fixed to the roof base material 1 with the roof screw 7, and the hanging wall 5 of the roof material 2U on the upstream side is covered with the upright wall 3 and joined. It is formed by screwing with a roofing screw 8.

特許文献１の支持装置は、金属板を折曲することにより形成された支持金具９により構成され、支持金具９は、前記垂下壁５に添設される支持壁１０と、該支持壁１０の上端から上流方向に延設された載置壁１１と、該載置壁の端部から下向きに形成されたＬ形の脚部１２を備えている。前記支持壁１０の下端には舌片１３が設けられている。 The support device of Patent Document 1 is composed of a support metal fitting 9 formed by bending a metal plate, and the support metal fitting 9 is a support wall 10 attached to the hanging wall 5 and a support wall 10 of the support wall 10. It includes a mounting wall 11 extending upstream from the upper end, and an L-shaped leg portion 12 formed downward from the end of the mounting wall. A tongue piece 13 is provided at the lower end of the support wall 10.

支持金具９は、金具用ビス１４を前記支持壁１０から垂下壁５及び起立壁３に貫通して打ち込むことにより屋根接合部６に固着され、屋根上に設置される。この状態で、前記載置壁１１が前記角度θ１とされた屋根勾配と平行に配置され、前記脚部１２が上流側の屋根材２Ｕに接支される。 The support metal fitting 9 is fixed to the roof joint 6 by driving the metal fitting screw 14 through the support wall 10 through the hanging wall 5 and the upright wall 3, and is installed on the roof. In this state, the above-mentioned mounting wall 11 is arranged parallel to the roof slope having the angle θ1, and the leg portion 12 is connected to and supported by the roof material 2U on the upstream side.

そこで、下流側と上流側に設置された複数の支持金具９、９に跨るようにして架台１５が搭載される。架台１５は、支持金具９の載置壁１１に載置され、該載置壁１１に設けられた孔１６を介して架台用ボルト１７により固定される。 Therefore, the gantry 15 is mounted so as to straddle the plurality of support metal fittings 9 and 9 installed on the downstream side and the upstream side. The gantry 15 is mounted on the mounting wall 11 of the support metal fitting 9, and is fixed by the pedestal bolt 17 through the hole 16 provided in the mounting wall 11.

しかしながら、特許文献１により提案された支持金具９は、現状の屋根に形成されている屋根接合部６の構造と屋根勾配（角度θ１）を何ら考慮せず、単純に屋根接合部６に固着する構成とされているため、次のような種々の問題がある。 However, the support metal fitting 9 proposed by Patent Document 1 simply adheres to the roof joint 6 without considering the structure of the roof joint 6 formed on the current roof and the roof slope (angle θ1). Since it is configured, there are various problems as follows.

（第１の問題点）
架台１５に太陽電池モジュール等のような盤状機器が搭載されている場合、強風により煽られると、図１９に示すように、架台１５に上向きの引張荷重Ｆ１が作用する。支持金具９の脚部１２は、図示矢印Ｑ１で示すように、容易に浮き上がるので、支持金具９の全体が引上げられる。支持金具９の唯一の固着個所は、金具用ビス１４により構成されている。金具用ビス１４は、垂下壁５と起立壁３の両壁に固定されているが、支持金具９は、一方の垂下壁５に固着されているに過ぎないから、垂下壁５と共に、図示矢印Ｑ２で示すように、容易に揺動する。このため、支持金具９は、金具用ビス１４を支点として支持壁１０が折れ曲がり、その際、金具用ビス１４が折損又は破断すると、固着状態を喪失して屋根上から脱落する危険がある。 (First problem)
When a board-shaped device such as a solar cell module is mounted on the gantry 15, when it is fanned by a strong wind, an upward tensile load F1 acts on the gantry 15 as shown in FIG. As shown by the arrow Q1 in the drawing, the leg portion 12 of the support metal fitting 9 is easily lifted, so that the entire support metal fitting 9 is pulled up. The only fixing point of the support metal fitting 9 is composed of a metal fitting screw 14. The metal fitting screw 14 is fixed to both the hanging wall 5 and the upright wall 3, but the support metal fitting 9 is only fixed to one of the hanging walls 5, so that the arrow is shown together with the hanging wall 5. As shown in Q2, it swings easily. Therefore, in the support metal fitting 9, if the support wall 10 is bent with the metal fitting screw 14 as a fulcrum, and the metal fitting screw 14 is broken or broken at that time, there is a risk that the support metal fitting 9 loses its fixed state and falls off from the roof.

（第２の問題点）
複数の支持金具９に架設された架台１５は、屋根の下り勾配に沿って配置され、従って、太陽電池モジュール等の機器も下り勾配に沿って搭載されている。そこで、積雪等により架台１５が受ける荷重は、屋根勾配に沿う下流方向の分力として、図２０に示すように支持金具９に対する滑落方向の荷重Ｆ２を作用する。この際、前記金具用ビス１４は、支持壁１０の下孔を介して垂下壁５及び起立壁３にねじ込まれており、該金具用ビス１４の軸線が荷重Ｆ２の作用する方向に沿わせられている。このため、屋根勾配に沿う下流方向の荷重Ｆ２が作用したとき、図示鎖線Ｑ３で示すように、金具用ビス１４が容易に引き抜かれ、支持金具９が固着状態を失い、屋根に沿って滑落する危険がある。 (Second problem)
The pedestals 15 erected on the plurality of support fittings 9 are arranged along the downward slope of the roof, and therefore, devices such as solar cell modules are also mounted along the downward slope. Therefore, the load received by the gantry 15 due to snow cover or the like acts as a component force in the downstream direction along the roof slope, and the load F2 in the sliding direction acts on the support metal fitting 9 as shown in FIG. At this time, the metal fitting screw 14 is screwed into the hanging wall 5 and the upright wall 3 through the prepared hole of the support wall 10, and the axis of the metal fitting screw 14 is aligned with the direction in which the load F2 acts. ing. Therefore, when a load F2 in the downstream direction along the roof slope acts, the metal fitting screw 14 is easily pulled out, the support metal fitting 9 loses the fixed state, and slides down along the roof, as shown by the chain line Q3 in the figure. There is a danger.

（第３の問題点）
支持金具９は、現状の屋根に形成されている屋根接合部６の構造と屋根勾配（角度θ１）を何ら考慮せず、単純に屋根接合部６に固着する構成とされているため、図２１に示すように、支持壁１０が垂下壁５に圧着された固着状態において、屋根下地材１に対して垂直姿勢、つまり、鉛直線に対して前傾姿勢を保持した状態で固着されている。しかしながら、太陽電池モジュール等の重量物を搭載した架台１５の荷重Ｆ３は、鉛直方向の下向きに作用するため、図示鎖線Ｑ４で示すように、支持壁１０が座屈変形するおそれがある。 (Third problem)
FIG. 21 shows that the support metal fitting 9 is simply fixed to the roof joint 6 without considering the structure of the roof joint 6 formed on the current roof and the roof slope (angle θ1). As shown in the above, in the fixed state in which the support wall 10 is crimped to the hanging wall 5, the support wall 10 is fixed in a vertical posture with respect to the roof base material 1, that is, in a state of maintaining a forward leaning posture with respect to the vertical line. However, since the load F3 of the gantry 15 on which a heavy object such as a solar cell module is mounted acts downward in the vertical direction, the support wall 10 may buckle and deform as shown by the chain line Q4 in the figure.

（第４の問題点）
この点に関して、前記支持壁１０の強度を補うため、脚部１２が屋根材２Ｕに接支されている。しかしながら、豪雪地帯においては、積雪により、前記荷重Ｆ３が数百kgに及ぶことも珍しくない。そこで、このような大荷重Ｆ３が脚部１２にかかると、屋根材２Ｕが局部的に圧迫されるので、図２１に鎖線Ｑ５で示すように、屋根材２Ｕが陥没変形するおそれがある。 (Fourth problem)
In this regard, the legs 12 are attached to and supported by the roofing material 2U in order to supplement the strength of the support wall 10. However, in heavy snowfall areas, it is not uncommon for the load F3 to reach several hundred kg due to snow cover. Therefore, when such a large load F3 is applied to the leg portion 12, the roofing material 2U is locally compressed, so that the roofing material 2U may be depressed and deformed as shown by the chain line Q5 in FIG.

本発明は、上述の問題を悉く解決した機器搭載用支持装置及び支持方法を提供するものである。 The present invention provides a support device for mounting equipment and a support method that solves the above-mentioned problems.

そこで、本発明の支持装置が手段として構成したところは、上流の棟側から下流の軒側に向けて角度θ１の下り勾配を有する屋根下地材に敷設される金属製の屋根材に関して、各屋根材は、上流に向かう端部に起立壁と該起立壁から延びて屋根下地材に屋根用ビスでビス止めされる平板壁を連設し、下流に向かう端部に下向きの垂下壁を設けており、下流側に敷設された屋根材と上流側に敷設された屋根材の相互に、下流側の屋根材の起立壁に対して、上流側の屋根材の垂下壁を覆い被せ、該垂下壁を起立壁にビス止めすることにより屋根接合部を構成する屋根において、前記接合部に位置して屋根上に搭載される機器の架台を支持する支持装置であり、前記支持装置は、金具本体と、前記金具本体を前記接合部に固着する金具用ビスと、前記金具本体に架台を搭載した状態で固定する架台用ボルトにより構成されており、前記金具本体は、下流側の屋根材に載置される載置部と、前記起立壁と垂下壁の間に下方から挿入されるフック壁を備えた上向きフックと、下流側から前記垂下壁に臨まされる基壁部を一体に形成すると共に、前記基壁部にビス孔を設けており、下流側から前記ビス孔に挿入した金具用ビスを前記垂下壁と起立壁に貫通して螺入し、基壁部と垂下壁を相互に圧着すると共に、フック壁と起立壁を相互に圧着することにより、金具本体を接合部に固着するように構成して成る点にあり、これにより、上記第１の問題点が解決される。 Therefore, the support device of the present invention is configured as a means for each roof of the metal roofing material laid on the roof base material having a downward slope of an angle θ1 from the upstream ridge side to the downstream eaves side. As for the material, an upright wall extending from the upright wall and a flat plate wall extending from the upright wall and fastened with a roof screw to the roof base material are continuously provided, and a downward hanging wall is provided at the downstream end. The roofing material laid on the downstream side and the roofing material laid on the upstream side cover the upright wall of the roofing material on the downstream side with the hanging wall of the roofing material on the upstream side. Is a support device that supports the pedestal of the equipment that is located on the roof and is located at the joint in the roof that constitutes the roof joint by screwing the above to the upright wall, and the support device is the metal fitting body. , The metal fitting body is composed of a metal fitting screw for fixing the metal fitting body to the joint portion and a pedestal bolt for fixing the metal fitting body with the pedestal mounted on the metal fitting body, and the metal fitting body is placed on a roofing material on the downstream side. An upward hook having a hook wall inserted from below between the upright wall and the hanging wall, and a base wall part facing the hanging wall from the downstream side are integrally formed. A screw hole is provided in the base wall portion, and a metal fitting screw inserted into the screw hole from the downstream side is screwed through the hanging wall and the upright wall to crimp the base wall portion and the hanging wall to each other. At the same time, the hook wall and the upright wall are crimped to each other so that the metal fitting body is fixed to the joint portion, which solves the first problem.

この際、前記ビス孔の軸線は、屋根下地材の下り勾配に沿う屋根材の平面Ｐに対して角度θ３で上向き傾斜する軸線Ｒに沿って形成することが好ましく、これにより、上記第２の問題点が解決される。 At this time, the axis of the screw hole is preferably formed along the axis R which is inclined upward at an angle θ3 with respect to the plane P of the roofing material along the downward slope of the roof base material. The problem is solved.

前記金具本体は、前記載置部の上方位置で架台を搭載する搭載部と、前記搭載部を支持する支持壁を一体に形成し、前記支持壁は、屋根下地材の下り勾配に沿う屋根材の平面Ｐに直交する垂直線Ｖに対して上流側に向けて角度θ２で傾斜させられていることが好ましく、これにより、上記第３の問題点が解決される。 The metal fitting body integrally forms a mounting portion for mounting the gantry at a position above the above-mentioned mounting portion and a support wall for supporting the mounting portion, and the support wall is a roofing material along a downward slope of the roof base material. It is preferable that the vertical line V orthogonal to the plane P is inclined toward the upstream side at an angle θ2, which solves the third problem.

前記支持壁は、上流側に配置された第１支持壁と、下流側に配置された第２支持壁を備えており、第１支持壁と第２支持壁を下流側の屋根材に支持させるように構成することが好ましく、下向きの鉛直荷重を支持壁により好適に支持することができるので、これにより、上記第４の問題点が解決される。 The support wall includes a first support wall arranged on the upstream side and a second support wall arranged on the downstream side, and the first support wall and the second support wall are supported by a roofing material on the downstream side. The above-mentioned fourth problem is solved by the above-mentioned fourth problem because the downward vertical load can be more preferably supported by the support wall.

更に、本発明の支持方法が手段として構成したところは、上記の支持装置を使用することにより屋根上に機器を搭載する方法であり、（Ａ）屋根の接合部において垂下壁と起立壁をビス止めした接合用ビスを取外し、垂下壁を起立壁から上向きに離反させることにより、平板壁の上方空間を開放させる工程と、（Ｂ）既設の屋根用ビスに近隣する個所に位置して新たな屋根用ビスを平板壁に打ち込むことにより、屋根下地材に対する平板壁の固着力を増強させる工程と、（Ｃ）その後、上向きフックのフック壁を起立壁に臨ませた状態で金具本体を下流側の屋根材に載置すると共に、垂下壁を下降させて基壁部とフック壁の間に挿入する工程と、（Ｄ）次いで、下流側からビス孔に挿入した金具用ビスを垂下壁と起立壁に貫通して螺入することにより、基壁部と垂下壁を相互に圧着すると共に、フック壁と起立壁を相互に圧着することにより、金具本体を接合部に固着する工程と、（Ｅ）前記金具本体の上に架台を搭載して固定すると共に、該架台に機器を搭載する工程とから成る点にある。 Further, the support method of the present invention is configured as a means by mounting the device on the roof by using the above support device, and (A) screwing the hanging wall and the upright wall at the joint of the roof. The process of opening the space above the flat plate wall by removing the stopped joining screw and separating the hanging wall upward from the standing wall, and (B) a new location near the existing roof screw. The process of increasing the adhesion of the flat plate wall to the roof base material by driving the roof screw into the flat plate wall, and (C) after that, the metal fitting body is placed on the downstream side with the hook wall of the upward hook facing the upright wall. The process of placing the roofing material on the roofing material and lowering the hanging wall and inserting it between the base wall and the hook wall, and (D) then, the metal fitting screw inserted into the screw hole from the downstream side stands up with the hanging wall. The process of fixing the metal fitting body to the joint by crimping the base wall and the hanging wall to each other by penetrating through the wall and crimping the hook wall and the upright wall to each other, and (E). ) The point is that the pedestal is mounted and fixed on the metal fitting body, and the device is mounted on the pedestal.

本発明によれば、屋根上に設置した状態で、上向きの荷重Ｆ１、滑落方向の荷重Ｆ２、下向きの荷重Ｆ３に対して、強固に耐えることができ、機器を搭載した架台を安定して支持する支持装置２０と支持方法の提供が可能になる。 According to the present invention, when installed on the roof, it can firmly withstand an upward load F1, a sliding direction load F2, and a downward load F3, and stably supports a gantry on which the equipment is mounted.

前記第１支持壁２８ａの下端部は、前記上向きフック２６のフック壁２６ｂと平行な基壁部２９を構成しており、該基壁部２９には前記フック壁２６ｂの上方に臨むビス孔３３が開設されている。この際、ビス孔３３の軸線は、屋根材２の平面Ｐに対して下流方向に向けて角度θ３で上向き傾斜する軸線Ｒに沿うように形成されている。 The lower end of the first support wall 28a constitutes a base wall portion 29 parallel to the hook wall 26b of the upward hook 26, and the base wall portion 29 has a screw hole 33 facing above the hook wall 26b. Has been opened. At this time, the axis of the screw hole 33 is formed along the axis R which is inclined upward at an angle θ3 toward the downstream direction with respect to the plane P of the roofing material 2.

更に、第２支持壁２８ｂには前記ビス孔３３に連通する導入孔３４が開設されており、該導入孔３４の軸線も前記軸線Ｒに沿うように形成されている。 Further, the second support wall 28b is provided with an introduction hole 34 communicating with the screw hole 33, and the axis of the introduction hole 34 is also formed along the axis R.

前記ビス孔３３は、金具用ビス２２の軸部を挿通するが頭部を挿通しない小径孔により構成され、導入孔３４は、金具用ビス２２を締結する回転工具を挿通させる大径孔により構成されている。ビス孔３３と導入孔３４から成る１組の孔は、角筒部２５の横方向に複数組を設けることが好ましく、図示実施形態の場合、２組が設けられている。 The screw hole 33 is composed of a small-diameter hole through which the shaft portion of the metal fitting screw 22 is inserted but not through the head, and the introduction hole 34 is composed of a large-diameter hole through which a rotary tool for fastening the metal fitting screw 22 is inserted.

（支持装置の設置と架台の搭載）
図５ないし図７は、屋根上に支持装置２０を設置する方法と、設置された支持装置２０に架台２３を搭載する方法を示している。 (Installation of support device and installation of pedestal)
5 to 7 show a method of installing the support device 20 on the roof and a method of mounting the gantry 23 on the installed support device 20.

図５に示すように、設置に先立ち、屋根材２の屋根接合部６に設けられた接合用ビス８を取外すことにより、屋根材２Ｕの垂下壁５を屋根材２Ｄの起立壁３から上向きに離反させる。この際、上流側の屋根材２Ｕを大きく離反させると、下流側の屋根材２Ｄの平板壁４の上方空間が開放されるので、既設の屋根用ビス７に隣り合う個所に位置して新たな屋根用ビス７ａを打ち込み、これにより、屋根下地材１に対する平板壁４の固着力を増強する。 As shown in FIG. 5, prior to installation, by removing the joining screw 8 provided at the roof joint portion 6 of the roofing material 2, the hanging wall 5 of the roofing material 2U is turned upward from the standing wall 3 of the roofing material 2D. Separate. At this time, if the roofing material 2U on the upstream side is largely separated, the space above the flat plate wall 4 of the roofing material 2D on the downstream side is opened. The roof screw 7a is driven in, thereby increasing the adhesive force of the flat plate wall 4 to the roof base material 1.

後述のように、支持装置２０を構成する金具本体２１の屋根材２に対する固着は、金具用ビス２２を唯一の手段としており、その固着強度は、平板壁４の固着状態に依存することになるので、新たな屋根用ビス７ａによる増し打ちを行うことにより、平板壁４の堅牢な固着を確保するのが良い。この点に関して、本発明は、金具本体２１の設置に際して、必ず上流側の屋根材２Ｕを上向きに持ち上げる工程を伴うものであるから、そのときにビスの増し打ちを行えば、特に作業工程の煩雑化等を招来することはなく、簡単な作業で平板壁４の固着強度を向上させ、その結果、金具本体２１の高い固着強度を実現することができる。 As will be described later, the metal fitting main body 21 constituting the support device 20 is fixed to the roof material 2 only by using the metal fitting screw 22, and the fixing strength depends on the fixing state of the flat plate wall 4. Therefore, it is preferable to secure the solid fixing of the flat plate wall 4 by performing additional striking with a new roofing screw 7a. In this regard, the present invention always involves a step of lifting the roofing material 2U on the upstream side upward when installing the metal fitting body 21, and therefore, if additional screws are struck at that time, the work process is particularly complicated. The fixing strength of the flat plate wall 4 can be improved by a simple operation, and as a result, the high fixing strength of the metal fitting body 21 can be realized.

前記垂下壁５を持ち上げた状態で、図５に示すように、金具本体２１の上向きフック２６を起立壁３に臨ませ、その後、図６に示すように、載置部３０ａを下り勾配に沿う下流側の屋根材２Ｄの上に載置すると共に、上流側の屋根材２Ｕを元の位置に戻し、垂下壁５を起立壁３に覆い被せ、該垂下壁５の下端部を上向きフック２６のフック壁２６ｂと基壁部２９の間に挿入する。この状態で、金具本体２１は、仮止め状態として安定設置され、その後の作業を容易とする。 With the hanging wall 5 lifted, as shown in FIG. 5, the upward hook 26 of the metal fitting body 21 faces the upright wall 3, and then, as shown in FIG. 6, the mounting portion 30a is along the downward slope. It is placed on the roofing material 2D on the downstream side, the roofing material 2U on the upstream side is returned to the original position, the hanging wall 5 is covered with the upright wall 3, and the lower end portion of the hanging wall 5 is placed on the upward hook 26. It is inserted between the hook wall 26b and the base wall portion 29. In this state, the metal fitting body 21 is stably installed in a temporarily fixed state, facilitating subsequent work.

金具本体２１を屋根接合部６に固着するため、金具用ビス２２が導入孔３４からビス孔３３に挿入され、垂下壁５及び起立壁３に螺入される。この際、上述のように、金具用ビス２２は、屋根材２の平面Ｐに対して角度θ３で上向き傾斜する軸線Ｒに沿って挿入されるので、電動ドライバー等の工具が屋根材２の上面に干渉するようなことはなく、作業を容易に行うことができる。 In order to fix the metal fitting body 21 to the roof joint portion 6, the metal fitting screw 22 is inserted into the screw hole 33 from the introduction hole 34 and screwed into the hanging wall 5 and the upright wall 3. At this time, as described above, since the metal fitting screw 22 is inserted along the axis R which is inclined upward at an angle θ3 with respect to the plane P of the roofing material 2, a tool such as an electric screwdriver is inserted on the upper surface of the roofing material 2. The work can be easily performed without interfering with the above.

図７に示すように、金具用ビス２２は、上向きフック２６のフック壁２６ｂを挟んだ状態で垂下壁５と起立壁３を締結する。駆動回転される金具用ビス２２の螺糸により、図７（Ｂ）に矢印Ｋで示すように、垂下壁５と起立壁３が引き寄せられるので、金具本体２５の基壁部２９と垂下壁５が相互に圧着され、しかも、フック壁２６ｂと起立壁３が相互に圧着される。この状態から、更に金具用ビス２２を締結すると、図示鎖線で示すように、起立壁３がフック壁２６ｂの上方で基壁部２９に向けて引き寄せられる。このように、垂下壁５と起立壁３は、その間にフック壁２６ｂを介在した状態で、該フック壁２６ｂを挟着するように締結されるので、金具用ビス２２の締結力が極めて高くなり、これにより、金具本体２５の高い固着強度が得られる。 As shown in FIG. 7, the metal fitting screw 22 fastens the hanging wall 5 and the upright wall 3 with the hook wall 26b of the upward hook 26 sandwiched between them. As shown by the arrow K in FIG. 7B, the hanging wall 5 and the standing wall 3 are attracted by the thread of the metal fitting screw 22 that is driven and rotated, so that the base wall portion 29 and the hanging wall 5 of the metal fitting body 25 are attracted to each other. Are crimped to each other, and the hook wall 26b and the upright wall 3 are crimped to each other. When the metal fitting screw 22 is further fastened from this state, the upright wall 3 is pulled toward the base wall portion 29 above the hook wall 26b as shown by the chain line shown in the figure. In this way, the hanging wall 5 and the upright wall 3 are fastened so as to sandwich the hook wall 26b with the hook wall 26b interposed therebetween, so that the fastening force of the metal fitting screw 22 becomes extremely high. As a result, a high fixing strength of the metal fitting body 25 can be obtained.

以上のようにして金具用ビス２２により金具本体２５を屋根接合部６に固着した後は、図８に示すように、金具本体２５における頂壁３１の搭載部３１ａに架台２３を搭載すると共に、翼部２７の保持部３５に保持した架台用ボルト２４で架台２３を固定すれば良い。 After the metal fitting body 25 is fixed to the roof joint 6 by the metal fitting screw 22 as described above, as shown in FIG. 8, the gantry 23 is mounted on the mounting portion 31a of the top wall 31 of the metal fitting body 25. The gantry 23 may be fixed by the gantry bolt 24 held by the holding portion 35 of the wing portion 27.

（上向き荷重を受けたときの作用）
架台２３に太陽電池モジュール等のような盤状機器が搭載されている場合、強風により煽られると、図９に示すように、架台２３に上向きの引張荷重Ｆ１が作用し、架台用ボルト２４を介して翼部２７が引き上げ方向の力を受ける。その際、図示のように、唯一の固着手段を構成する金具用ビス２２に固定されたビス孔３３を支点とするモーメントＭ１を生じることになるが、この場合、該モーメントＭ１に対して、角筒部２５の第１支持壁２８ａと第２支持壁２８ｂを支持する底壁３０と、上向きフック２６が好適に対抗し、金具本体２５の設置姿勢を保持する。 (Action when receiving an upward load)
When a board-shaped device such as a solar cell module is mounted on the gantry 23, when it is fanned by a strong wind, an upward tensile load F1 acts on the gantry 23 as shown in FIG. 9, and the gantry bolt 24 is pressed. Through this, the wing portion 27 receives a force in the pulling direction. At that time, as shown in the drawing, a moment M1 having a screw hole 33 fixed to the metal fitting screw 22 constituting the only fixing means as a fulcrum is generated. In this case, an angle is generated with respect to the moment M1. The bottom wall 30 that supports the first support wall 28a and the second support wall 28b of the tubular portion 25 and the upward hook 26 preferably oppose each other, and hold the installation posture of the metal fitting body 25.

角筒部２５の底壁３０は、載置部３０ａを屋根材２Ｄの平坦面に面接触状態で接支し、前記モーメントＭ１に耐え、第１支持壁２８ａと第２支持壁２８ｂにより搭載部３１ａを強固に支持する。上向きフック２６は、フック壁２６ｂが金具用ビス２２で締結された垂下壁５と起立壁３により強固に挟持されているので、浮き上がることはない。しかも、両壁５、３の挟持力に加えて、モーメントＭ１に対抗する方向から、上向きフック２６のフック壁２６ｂが垂下壁５の下端に係止すると共に、該フック壁２６ｂの先端が起立壁３（金具用ビス２２により引き寄せられた変形部）に係止しているので、該モーメントＭ１に伴う引き上げ力に耐える。 The bottom wall 30 of the square tube portion 25 supports and supports the mounting portion 30a on the flat surface of the roofing material 2D in a surface contact state, withstands the moment M1, and is mounted by the first support wall 28a and the second support wall 28b. Firmly supports 31a. The upward hook 26 does not rise because the hook wall 26b is firmly sandwiched between the hanging wall 5 and the standing wall 3 fastened by the metal fitting screw 22. Moreover, in addition to the holding forces of both walls 5 and 3, the hook wall 26b of the upward hook 26 is locked to the lower end of the hanging wall 5 from the direction opposed to the moment M1, and the tip of the hook wall 26b is an upright wall. Since it is locked to 3 (the deformed portion attracted by the metal fitting screw 22), it withstands the pulling force accompanying the moment M1.

（下流側に向かう滑落方向の荷重を受けたときの作用）
図１０に示すように、積雪等により架台２３が受ける下向き荷重により、屋根勾配に沿う下流方向の荷重Ｆ２が作用した場合、支持装置２０は、屋根勾配の平面Ｐに沿って滑落方向の力を受けるが、該平面Ｐに対して、金具用ビス２２は、上述のように、その軸線Ｒが角度θ３で傾斜させられた状態で垂下壁５及び起立壁３に締着されているので、容易に引き抜かれることはなく、支持装置２０の固着状態を保持し、屋根に沿って滑落することはない。 (Action when a load is applied in the sliding direction toward the downstream side)
As shown in FIG. 10, when a load F2 in the downstream direction along the roof slope acts due to a downward load received by the gantry 23 due to snow cover or the like, the support device 20 exerts a force in the sliding direction along the plane P of the roof slope. However, as described above, the metal fitting screw 22 is fastened to the hanging wall 5 and the upright wall 3 in a state where the axis R is inclined at an angle θ3 with respect to the plane P, so that it is easy. It is not pulled out, keeps the support device 20 in a fixed state, and does not slide down along the roof.

この際、上述のように、支持装置２０の設置に先立ち、屋根材２Ｄの平板壁４に新たな屋根用ビス７ａを増し打ちしているので、極めて大きな荷重Ｆ２が作用したときでも、平板壁４が屋根下地材１から離脱することはなく、該屋根材２Ｄと共に支持装置２０を滑落させるような危険を招来することはない。 At this time, as described above, since the new roofing screw 7a is additionally struck on the flat plate wall 4 of the roofing material 2D prior to the installation of the support device 20, the flat plate wall even when an extremely large load F2 acts. 4 does not separate from the roof base material 1, and does not pose a danger of sliding the support device 20 together with the roof material 2D.

（下向き荷重を受けたときの作用）
図１１に示すように、支持装置２０は、金具本体２５が角筒部２５により剛体構造とされており、底壁３０の載置部３０ａを屋根材２Ｄに沿って載置した状態で、第１支持壁２８ａと第２支持壁２８ｂをほぼ鉛直方向に起立させている。従って、太陽電池モジュール等の重量物を搭載した架台２３から鉛直方向の下向きに作用する荷重Ｆ３は、第１支持壁２８ａと第２支持壁２８ｂにより直下から対向して好適に支持され、しかも、屋根材２Ｄの平面に面接触された底壁３０の載置部３０ａにより安定した状態で支持される。 (Action when receiving a downward load)
As shown in FIG. 11, in the support device 20, the metal fitting body 25 has a rigid body structure due to the square tube portion 25, and the mounting portion 30a of the bottom wall 30 is mounted along the roof material 2D. The first support wall 28a and the second support wall 28b are erected in the substantially vertical direction. Therefore, the load F3 acting downward in the vertical direction from the gantry 23 on which a heavy object such as a solar cell module is mounted is suitably supported by the first support wall 28a and the second support wall 28b so as to face each other from directly below. It is supported in a stable state by the mounting portion 30a of the bottom wall 30 which is in surface contact with the flat surface of the roofing material 2D.

ところで、荷重Ｆ３が金具本体２５の全体ではなく、仮に、架台用ボルト２４を有する翼部２７に対して局所的に大きくかかる場合、図示のように、唯一の固着手段を構成する金具用ビス２２に固定されたビス孔３３を支点とするモーメントＭ２を生じることになるが、その場合、該モーメントＭ２に対して、上向きフック２６が好適に対抗して金具本体２５の設置姿勢を保持する。図示のように、上向きフック２６は、連設壁２６ａを起立壁３から折曲された屋根材２Ｄに当接することにより回動を阻止され、フック壁２６ｂを金具用ビス２２に固着された起立壁３に当接することにより回動を阻止されるので、これによりモーメントＭ２に屈することなく耐えることができる。 By the way, if the load F3 is applied locally to the wing portion 27 having the pedestal bolt 24 instead of the entire metal fitting body 25, as shown in the figure, the metal fitting screw 22 constituting the only fixing means A moment M2 is generated with the screw hole 33 fixed to the fulcrum as a fulcrum. In that case, the upward hook 26 preferably opposes the moment M2 and holds the installation posture of the metal fitting body 25. As shown in the figure, the upward hook 26 is prevented from rotating by contacting the continuous wall 26a with the roofing material 2D bent from the upright wall 3, and the upright hook wall 26b is fixed to the metal fitting screw 22. Since the rotation is prevented by abutting against the wall 3, it is possible to withstand the moment M2 without yielding.

図１２ないし図１４は、支持装置２０の第２実施形態を示している。支持装置２０は、屋根接合部６に搭載される金具本体２１と、前記金具本体２１を屋根接合部６に固着する金具用ビス２２と、前記金具本体２１の上に載置された架台２３を固定するための架台用ボルト２４により構成されており、この点は、第１実施形態と同様である。 <Second Embodiment>
