Description

本発明は、太陽電池モジュールや太陽熱温水パネルなど、特定の機能を有する機能パネルの屋根への取付構造に関するものである。   The present invention relates to a structure for mounting a functional panel having a specific function such as a solar cell module or a solar hot water panel on a roof.

太陽電池モジュールなどの機能パネルを屋根の上に取り付ける工法の一つに、陶器瓦を葺いて形成される既存の屋根に機能パネルを取り付ける工法がある。   One method of attaching a functional panel such as a solar cell module on a roof is a method of attaching a functional panel to an existing roof formed by spreading ceramic tiles.

この工法は、まず既存の瓦のうち、所定箇所の瓦を撤去し、撤去した箇所に支持瓦１５を取り付け、縦桟１ａと横桟１ｂからなる複数本の桟材１を組んで形成される架台２をこの支持瓦１５によって支持する。次に、隣合う横桟１ｂの間に機能パネル３を嵌め込んで取り付けることによって、複数枚の機能パネル３を架台２に固定する。このようにして、架台２に支持した状態で複数枚の機能パネル３を屋根に取り付けることができるものである（図４、図６参照）。   This construction method is formed by first removing a tile at a predetermined location from existing tiles, attaching a support tile 15 to the removed location, and assembling a plurality of crosspieces 1 including a vertical beam 1a and a horizontal beam 1b. The gantry 2 is supported by the support tile 15. Next, a plurality of functional panels 3 are fixed to the gantry 2 by fitting the functional panels 3 between adjacent horizontal rails 1b. In this way, a plurality of functional panels 3 can be attached to the roof while being supported by the gantry 2 (see FIGS. 4 and 6).

そしてこのように太陽電池モジュールなどの機能パネル３を架台２に取り付けるにあたって、機能パネル３を金属製の架台２にアース接続する必要がある。機能パネル３を架台２にアースするにあたっては、例えば図７に示すような、両側端に機能パネル接触片７を垂下して設けた断面コ字形の導通部材４を用いて行なわれている（例えば特許文献１等参照）。すなわち、横桟１ｂを介して隣合う機能パネル３，３の端部間に跨るように横桟１ｂの上に導通部材４を配設し、導通部材４を横桟１ｂの上に取り付けることによって、導通部材４の両側端の機能パネル接触片７の下端をそれぞれ、各機能パネル３の外周に取り付けられた金属製外枠１６に接触させ、導電部材４によって機能パネル３を架台２にアース接続することができるものである（図２参照）。
特開平９−２５０２１９号公報（第１７図（ａ）（ｂ）） And when attaching the functional panel 3 such as a solar cell module to the gantry 2 in this way, it is necessary to ground the functional panel 3 to the metal gantry 2. The functional panel 3 is grounded to the gantry 2 using, for example, a conductive member 4 having a U-shaped cross-section provided by hanging the functional panel contact pieces 7 on both side ends as shown in FIG. (See Patent Document 1). That is, by arranging the conductive member 4 on the horizontal beam 1b so as to straddle between the end portions of the adjacent functional panels 3 and 3 via the horizontal beam 1b, and attaching the conductive member 4 on the horizontal beam 1b. The lower ends of the functional panel contact pieces 7 on both sides of the conductive member 4 are brought into contact with the metal outer frame 16 attached to the outer periphery of each functional panel 3, and the functional panel 3 is grounded to the gantry 2 by the conductive member 4. (See FIG. 2).
JP-A-9-250219 (FIGS. 17 (a) and (b))

図７のように形成される導通部材４を用いて機能パネル３を架台２にアース接続するにあたって、導通部材４の機能パネル接触片７は先端が線状に機能パネル３の金属製外枠１６の表面に接触しているが、外枠１６の表面には腐食防止のために塗装やアルマイト処理などが施されており、機能パネル接触片７は外枠１６に電気的に導通した状態で接触していないことがある。また導通部材４はその下面が横桟１ｂの上面に面で接触しているが、横桟１ｂの表面にも同様に腐食防止のために塗装やアルマイト処理などが施されており、導通部材４は横桟１ｂに電気的に導通した状態で接触していないことがある。従って、上記のような導通部材４では架台２への機能パネル３のアース接続を確実に行なうことができないという問題があった。   When the functional panel 3 is grounded to the gantry 2 using the conductive member 4 formed as shown in FIG. 7, the functional panel contact piece 7 of the conductive member 4 has a metal outer frame 16 of the functional panel 3 that has a linear tip. However, the surface of the outer frame 16 is painted or anodized to prevent corrosion, and the functional panel contact piece 7 is in electrical contact with the outer frame 16. There are things that are not. Further, the lower surface of the conductive member 4 is in surface contact with the upper surface of the horizontal beam 1b, but the surface of the horizontal beam 1b is similarly coated or anodized to prevent corrosion. May not be in contact with the horizontal rail 1b in an electrically conductive state. Therefore, the conductive member 4 as described above has a problem that the ground connection of the functional panel 3 to the gantry 2 cannot be reliably performed.

本発明は上記の点に鑑みてなされたものであり、導通部材で機能パネルを架台にアース接続するにあたって、架台に機能パネルを確実にアース接続することができる機能パネルの取付構造を提供することを目的とするものである。   The present invention has been made in view of the above points, and provides a functional panel mounting structure capable of reliably grounding a functional panel to a gantry when the functional panel is grounded to a gantry with a conductive member. It is intended.

本発明の請求項１に係る機能パネルの取付構造は、屋根の上に縦と横の複数本の桟材１を組んで形成される架台２を取り付け、隣合う桟材１間に機能パネル３を配置して架台２に機能パネル３を固定することによって、屋根に複数枚の機能パネル３を取り付けるようにした機能パネルの取付構造において、導通部材４に下側程横幅が小さくなる台形形状に形成した桟材接触片５を下方へ突出して設けると共に、下端に先端が尖った接触突起６を有する機能パネル接触片７を桟材接触片５と直交する配置で導通部材４の両側端部に下方へ突出して設け、桟材１を介して隣合う各機能パネル３の端部間に跨るように桟材１の上に導通部材４を配設し、桟材１に長手方向に沿って設けられる桟溝８の上面開口に桟材接触片５を嵌め込んで桟材接触片５の両側端縁をこの開口の両縁に圧接させると共に、桟材１を介して隣合う各機能パネル３の端部の金属部材に機能パネル接触片７の接触突起６の先端を圧接させた状態で、導通部材４を桟材１に固定して成ることを特徴とするものである。   In the functional panel mounting structure according to claim 1 of the present invention, a frame 2 formed by assembling a plurality of vertical and horizontal crosspieces 1 is mounted on a roof, and the functional panel 3 is placed between adjacent crosspieces 1. In the functional panel mounting structure in which a plurality of functional panels 3 are mounted on the roof by fixing the functional panel 3 to the gantry 2, the conductive member 4 has a trapezoidal shape with a lower lateral width toward the lower side. The formed crosspiece contact piece 5 is provided so as to protrude downward, and a functional panel contact piece 7 having a contact protrusion 6 having a sharp tip at the lower end is disposed at both end portions of the conducting member 4 in an arrangement orthogonal to the crosspiece contact piece 5. A conductive member 4 is disposed on the crosspiece 1 so as to extend between the end portions of the adjacent functional panels 3 via the crosspiece 1 and provided along the longitudinal direction on the crosspiece 1. The crosspiece contact piece 5 is fitted into the top opening of the crosspiece 8 and the crosspiece contact piece Both end edges of the functional panel are in pressure contact with both edges of the opening, and the tip of the contact projection 6 of the functional panel contact piece 7 is in pressure contact with the metal member at the end of each adjacent functional panel 3 through the crosspiece 1 Thus, the conductive member 4 is fixed to the crosspiece 1.

また請求項２の発明は、請求項１において、導通部材４の機能パネル接触片７の下端に、幅方向の複数箇所に接触突起６を設けて成ることを特徴とするものである。   The invention of claim 2 is characterized in that, in claim 1, contact protrusions 6 are provided at a plurality of positions in the width direction at the lower end of the functional panel contact piece 7 of the conducting member 4.

導通部材４に設けた機能パネル接触片７の下端には、先端が尖った接触突起６が形成してあるので、機能パネル接触片７は接触突起６の尖った先端が機能パネル３の金属部材の表面に圧接するものであり、金属部材の表面に塗装やアルマイト処理などが施されていても、接触突起６がこれを突き抜けて金属部材の下地に機能パネル接触片７を接触させることができる。また、導通部材４に下側程横幅が小さくなる台形形状に形成した桟材接触片５を設け、桟材１の桟溝８の開口両縁に桟材接触片５の両側端縁を圧接させているので、桟材接触片５は食い込むように桟材１に圧接するものであり、桟材１の表面に塗装やアルマイト処理などが施されていても、これを突き抜けて桟材１の金属下地に桟材接触片５を接触させることができる。   Since the contact projection 6 having a sharp tip is formed at the lower end of the functional panel contact piece 7 provided on the conductive member 4, the functional panel contact piece 7 has a pointed tip of the contact projection 6 at the metal member of the functional panel 3. Even if the surface of the metal member is painted or anodized, the contact protrusion 6 can penetrate the surface of the metal member and allow the functional panel contact piece 7 to contact the base of the metal member. . Further, a crosspiece contact piece 5 formed in a trapezoidal shape whose lateral width decreases toward the lower side is provided on the conductive member 4, and both side edges of the crosspiece contact piece 5 are pressed against both edges of the crosspiece groove 8 of the crosspiece 1. Therefore, the crosspiece contact piece 5 is pressed against the crosspiece 1 so as to bite in. Even if the surface of the crosspiece 1 is painted or anodized, the metal of the crosspiece 1 is penetrated through it. The crosspiece contact piece 5 can be brought into contact with the base.

従って、導通部材４で機能パネル３を架台２にアース接続するにあたって、導通部材４を機能パネル３の金属部材や桟材１の金属下地に接触させて、架台２に機能パネル３を確実にアース接続することができるものである。   Accordingly, when the functional panel 3 is grounded to the gantry 2 by the conductive member 4, the conductive member 4 is brought into contact with the metal member of the functional panel 3 or the metal base of the crosspiece 1 to securely ground the functional panel 3 to the gantry 2. It can be connected.

以下、本発明を実施するための最良の形態を説明する。   Hereinafter, the best mode for carrying out the present invention will be described.

機能パネル３として太陽電池モジュールを用い、既存の陶器瓦の屋根に機能パネル３を後付けで取り付ける工法について実施の形態を説明すると、まず、既存の瓦１８のうち、所定箇所の瓦１８を撤去し、撤去した箇所に支持瓦１５を取り付ける。図６は屋根の瓦１８の配置を示すものであり、架台２を取り付けるのに必要な箇所の瓦１８を撤去して支持瓦１５（図６に斜線で示す）を取り付けるようにしてある。支持瓦１５の上面には図４に示すように金具受け１９が一体に突設してあり、この金具受け１９に下固定金具２０が取り付けてある。金具受け１９への下固定金具２０の取り付けは、下固定金具２０に下面側へ突出して設けた下固定片２１と金具受け１９にボルトナット２２を通して螺結することによって行なうものである。   An embodiment of a method for retrofitting a functional panel 3 to a roof of an existing ceramic tile using a solar cell module as the functional panel 3 will be described. First, the tile 18 at a predetermined location is removed from the existing tile 18. The support tile 15 is attached to the removed part. FIG. 6 shows the arrangement of the roof tiles 18, where the tiles 18 at positions necessary for mounting the mount 2 are removed and the support tiles 15 (indicated by hatching in FIG. 6) are attached. As shown in FIG. 4, a bracket receiver 19 is integrally projected on the upper surface of the support tile 15, and a lower fixing bracket 20 is attached to the bracket receiver 19. The lower fixing bracket 20 is attached to the bracket receiver 19 by screwing the lower fixing piece 21 provided on the lower fixing bracket 20 so as to protrude from the lower surface and the bracket receiver 19 through a bolt and nut 22.

架台２はアルミニウムなどの金属材で作製される桟材１を組み付けて形成されるものであるが、桟材１としては縦（軒棟方向）の縦桟１ａと横（軒あるいは棟と平行）の横桟１ｂが用いられる。そしてまず縦桟１ａを軒棟方向に沿って複数配置されている各支持瓦１５の上に亘るように配置し（図６参照）、下固定金具２０によって縦桟１ａを支持瓦１５に取り付ける。下固定金具２０の上面に一対の平行な上固定片２３が設けてあり、上固定片２３の間に嵌め込んだ状態で下固定金具２０の上に縦桟１ａを載置し、上固定片２３と縦桟１ａとをボルトナット２４で結合することによって、下固定金具２０に縦桟１ａを固定し、下固定金具２０及び金具受け１９によって支持瓦１５に縦桟１を取り付けることができるものである。   The gantry 2 is formed by assembling a crosspiece 1 made of a metal material such as aluminum. As the crosspiece 1, a vertical (eave building direction) vertical cross 1a and a horizontal (parallel to the eave or the ridge) are used. The horizontal beam 1b is used. First, a plurality of vertical rails 1 a are arranged so as to extend over the respective supporting tiles 15 arranged along the eaves-ridge direction (see FIG. 6), and the vertical rails 1 a are attached to the supporting tiles 15 by the lower fixing bracket 20.

A bolt 31 is passed from above into a hole (not shown) provided on the bottom surface of the plate and screw 31 is screwed into a screw hole 29 of the plate nut 30, whereby the vertical beam 1 a is interposed between the bottom surface of the horizontal beam 1 b and the plate nut 30. The horizontal beam 1b can be fixed on the vertical beam 1a so as to sandwich the locking piece 28. By attaching a plurality of horizontal beams 1b on the vertical beam 1a in this way, a plurality of vertical beams 1a in the eave building direction and a plurality of horizontal beams 1b parallel to the eave (or building) as shown in FIG. Can be formed, and the gantry 2 is supported on the roof by the support tile 15. In FIG. 4, 33 is a vertical beam cap attached to the ridge side end of the vertical beam 1a, and 34 is a horizontal beam cap attached to the end of the horizontal beam 1b.

本発明において機能パネル３としては、特に限定されるものではないが、太陽電池モジュールを使用することができる。太陽電池モジュールは複数の太陽電池セルをマトリクス状に配置して矩形の板状に形成されるものであり、図４に示すようにその四周の外縁を囲ってアルミニウムなどの金属製の外枠１６が取り付けてある。この外枠１６の外面の下部には断面Ｌ字形に屈曲して突出する係合片３５が一体に設けてあり、係合片３５の内側に上方へ開口する係合溝３６が形成されるようにしてある。   In the present invention, the functional panel 3 is not particularly limited, but a solar cell module can be used.

次に、上記のように縦桟１ａと横桟１ｂを組み付けて形成される架台２に機能パネル３を取り付ける施工について説明する。まず、図４に示すように機能パネル３を隣合う横桟１ｂの間に嵌め込み、機能パネル３の軒側と棟側の端部を各横桟１ｂの受け片２６の上に載置する。   Next, the construction for attaching the functional panel 3 to the gantry 2 formed by assembling the vertical beam 1a and the horizontal beam 1b as described above will be described. First, as shown in FIG. 4, the functional panel 3 is fitted between the adjacent horizontal rails 1b, and the end portions of the functional panel 3 on the eaves side and the ridge side are placed on the receiving pieces 26 of the horizontal rails 1b.

ここで、各横桟１ｂには複数本の係止ボルト４０が脱着自在に取り付けてある。係止ボルト４０は四角形のスライド板４１の上面にボルト４２を立設して形成されるものである。また横桟１ｂの桟溝８の上面開口両縁の各内面に相互に対向するようにスライド溝４３が長手方向の全長に亘って設けてある。そしてスライド板４１の両側端をそれぞれスライド溝４３に差し込んで係止した状態で横桟１ｂの長手方向にスライドさせることによって、横桟１ｂの任意の箇所において、ボルト４２を横桟１ｂの上方へ突出させた状態で係止ボルト４０を横桟１ｂに取り付けることができるものである。   Here, a plurality of locking bolts 40 are detachably attached to each horizontal rail 1b. The locking bolt 40 is formed by standing a bolt 42 on the upper surface of a rectangular slide plate 41. A slide groove 43 is provided over the entire length in the longitudinal direction so as to face each inner surface of both edges of the upper surface opening of the cross groove 8 of the horizontal cross 1b. Then, by sliding the both sides of the slide plate 41 in the longitudinal direction of the horizontal beam 1b while being inserted and locked in the slide grooves 43, the bolts 42 are moved upward of the horizontal beam 1b at any position of the horizontal beam 1b. The locking bolt 40 can be attached to the horizontal rail 1b in a protruding state.

次に、図１（ｂ）に示すように、ボルト通し孔３８を係止ボルト４０のボルト４２に上から被挿して、導通部材４を横桟１ｂの上を跨ぐように配置する。このように導通部材４を横桟１ｂの上に配置すると、導通部材４の各桟材接触片５が横桟１ｂの桟溝８の上面開口にはまり込むと共に、導通部材４の各機能パネル接触片７が、横桟１ｂを介して隣合う各機能パネル３の外枠１６の係合溝３６に差し込まれるようになっている。係止ボルト４０は機能パネル３の辺に沿った複数箇所において横桟１ｂに取り付けられるが、導通部材４は一つの係止ボルト４０に取り付けるようにするだけでよい。   Next, as shown in FIG. 1B, the bolt through hole 38 is inserted into the bolt 42 of the locking bolt 40 from above, and the conductive member 4 is disposed so as to straddle the horizontal rail 1b. When the conductive member 4 is arranged on the horizontal rail 1b as described above, each cross member contact piece 5 of the conductive member 4 fits into the upper surface opening of the cross groove 8 of the horizontal rail 1b and each functional panel of the conductive member 4 contacts with each functional panel. The piece 7 is inserted into the engaging groove 36 of the outer frame 16 of each adjacent functional panel 3 via the horizontal rail 1b. The locking bolts 40 are attached to the cross rail 1b at a plurality of locations along the side of the functional panel 3, but the conducting member 4 need only be attached to one locking bolt 40.

この後、カバー板４５を横桟１ｂの上に取り付ける。カバー板４５は機能パネル３の横方向（軒棟方向と垂直な方向）の辺と同程度の長さを有する細長い板で形成されるものであり、カバー板４５の両側端に係合押え片４６が下方へ屈曲して設けてある。カバー板４５には所定間隔で通孔４７が設けてあり、通孔４７に係止ボルト４０のボルト４２を被挿して横桟１ｂの上に被せると、カバー板４５は横桟１ｂを跨いで配置され、カバー板４５の各係合押さえ片４６が、横桟１ｂを介して隣合う各機能パネル３の外枠１６の係合溝３６に差し込まれるようになっている。   Thereafter, the cover plate 45 is mounted on the horizontal rail 1b. The cover plate 45 is formed by an elongated plate having the same length as the side of the functional panel 3 in the lateral direction (direction perpendicular to the eaves ridge direction). 46 is bent downward. Through holes 47 are provided in the cover plate 45 at a predetermined interval. When the bolts 42 of the locking bolts 40 are inserted into the through holes 47 and placed on the horizontal rail 1b, the cover plate 45 straddles the horizontal rail 1b. Each engagement pressing piece 46 of the cover plate 45 is inserted into the engagement groove 36 of the outer frame 16 of each adjacent functional panel 3 through the horizontal rail 1b.

そして、カバー板４５の上から袋ナットなどのナット４９を係止ボルト４０のボルト４２の上端部にねじ込み、ナット４９を締め付けてカバー板４５を係止ボルト４０によって横桟１ｂに固定する。カバー板４５の係合押え片４６は各機能パネル３の外枠１６の係合溝３６に係合されているので、このようにカバー板４５を横桟１ｂに固定することによって、図１（ａ）に示すように、カバー板４５で押えた状態で機能パネル３を横桟１ｂに固定することができ、架台２に機能パネル３を取り付けることができるものである。図４において５１は軒カバー板、５２には棟カバー板であり、それぞれ上記のカバー板４５の場合と同様に、機能パネル３の係合片３５に係合させた状態で、係止ボルト４０とナット４９の螺合によって、軒側端部に位置する横桟１ｂと、棟側端部に位置する横桟１ｂにそれぞれ取り付けられるものである。   Then, a nut 49 such as a cap nut is screwed onto the upper end portion of the bolt 42 of the locking bolt 40 from above the cover plate 45, and the nut 49 is tightened to fix the cover plate 45 to the horizontal rail 1 b with the locking bolt 40. Since the engagement pressing piece 46 of the cover plate 45 is engaged with the engagement groove 36 of the outer frame 16 of each functional panel 3, fixing the cover plate 45 to the horizontal rail 1b in this way allows the FIG. As shown to a), the function panel 3 can be fixed to the crosspiece 1b in the state pressed with the cover board 45, and the function panel 3 can be attached to the mount frame 2. FIG. 4, 51 is an eaves cover plate, and 52 is a ridge cover plate. Similarly to the case of the cover plate 45, the locking bolt 40 is engaged with the engagement piece 35 of the functional panel 3. And the nut 49 are screwed together to be attached to the horizontal beam 1b located at the eaves side end and the horizontal beam 1b located at the ridge side end.

またこのように係止ボルト４０のボルト４２にねじ込んだナット４９を締め付けると、カバー板４５を介して導通部材４が下方へ押さえ付けられる。このように導通部材４が押さえられると、導通部材４に設けた上側程横幅が大きくなる台形形状の桟材接触片５は横桟１ｂの桟溝８の開口内に圧入され、桟溝８の開口両縁に桟材接触片５の両側端の傾斜辺５ａが食い込むように接触して圧接する。従って、横桟１ｂの表面に塗装やアルマイト処理などが施されていても、これを突き抜けて桟材１ｂの金属下地に桟材接触片５を接触させることができるものである。またこのように導通部材４が押さえられると、導通部材４に設けた機能パネル接触片７は接触突起６の尖った先端によって機能パネル３の外枠１６の係合溝３６の溝底に圧接する。従って、外枠１６の表面に塗装やアルマイト処理などが施されていても、接触突起６によってこれを突き抜けて外枠１６の金属下地に機能パネル接触片７を接触させることができるものである。   Further, when the nut 49 screwed into the bolt 42 of the locking bolt 40 is tightened in this way, the conducting member 4 is pressed downward through the cover plate 45. When the conducting member 4 is pressed in this way, the trapezoidal crosspiece contact piece 5 whose width increases toward the upper side provided in the conducting member 4 is press-fitted into the opening of the crosspiece 8 of the crosspiece 1b. The inclined sides 5a at both ends of the crosspiece contact piece 5 are brought into contact with and pressed against both edges of the opening. Accordingly, even if the surface of the horizontal rail 1b is painted or anodized, the rail material contact piece 5 can be brought into contact with the metal base of the rail material 1b through the surface. When the conducting member 4 is pressed in this way, the functional panel contact piece 7 provided on the conducting member 4 is pressed against the groove bottom of the engaging groove 36 of the outer frame 16 of the functional panel 3 by the pointed tip of the contact protrusion 6. . Therefore, even if the surface of the outer frame 16 is painted or anodized, the functional panel contact piece 7 can be brought into contact with the metal base of the outer frame 16 through the contact protrusion 6.

このようにして、導通部材４で機能パネル３を架台２にアース接続するにあたって、導通部材４を機能パネル３の金属製外枠１６のような金属部材や、架台２を形成する桟材１の、金属下地に確実に接触させて導通させることができるものであり、機能パネル３を架台２に確実にアース接続することができるものである。   In this way, when the functional panel 3 is grounded to the gantry 2 by the conductive member 4, the conductive member 4 is a metal member such as the metal outer frame 16 of the functional panel 3 or the crosspiece 1 that forms the gantry 2. The metal panel can be reliably brought into contact with the base metal, and the functional panel 3 can be securely grounded to the gantry 2.

ここで、導通部材４の機能パネル接触片７の複数箇所に接触突起６を設けると、複数の接触突起６を機能パネル３の金属部材（外枠１６）に圧接させて接触させることができ、導通部材４と外枠１６との導通接続をより確実に行なうことができるものである。また横桟１ｂに沿って複数枚の機能パネル３を取り付ける場合に、このように機能パネル接触片７の複数箇所に接触突起６が設けてあると、横桟１ｂに沿った方向に隣合う機能パネル３の間に跨るように導通部材４を配置することによって、各機能パネル３の金属部材（外枠１６）に機能パネル接触片７の各接触突起６をそれぞれ圧接させて接触させることができるものであり、少ない枚数の導通部材４で多数枚の機能パネル３のアースをとることが可能になるものである。   Here, if the contact protrusions 6 are provided at a plurality of locations on the functional panel contact piece 7 of the conductive member 4, the plurality of contact protrusions 6 can be brought into pressure contact with the metal member (outer frame 16) of the function panel 3, The conductive connection between the conductive member 4 and the outer frame 16 can be more reliably performed. In addition, when a plurality of functional panels 3 are attached along the horizontal rail 1b, if the contact protrusions 6 are provided at a plurality of locations on the functional panel contact piece 7 as described above, functions adjacent to each other in the direction along the horizontal rail 1b. By disposing the conductive member 4 so as to straddle between the panels 3, the contact protrusions 6 of the functional panel contact piece 7 can be brought into pressure contact with the metal member (outer frame 16) of each functional panel 3. Thus, a large number of functional panels 3 can be grounded with a small number of conductive members 4.
