トップライト14には、各々矩形状に形成された網入りのガラス板(網入りガラス)28及び耐衝撃性を有する樹脂製の採光板30が用いられており、ガラス板28及び採光板30の各々は、光透過性を有する光透過性部材とされている。採光板30は、周辺部が内枠24の底板24Bの上方に配置されて、内枠24に取り付けられている。また、ガラス板28は、採光板30の上方に配置され、周縁部が防水ゴムなどの弾性部材を介して外枠26の嵌合部26Bに嵌合されて取り付けられている。 For the top light 14, a wire glass plate (wired glass) 28 formed in a rectangular shape and a resin-made lighting plate 30 having impact resistance are used. Each of them is a light-transmitting member having light-transmitting properties. The lighting plate 30 is attached to the inner frame 24 with its peripheral portion disposed above the bottom plate 24B of the inner frame 24 . Further, the glass plate 28 is arranged above the lighting plate 30, and the peripheral portion thereof is fitted and attached to the fitting portion 26B of the outer frame 26 via an elastic member such as waterproof rubber.

これにより、トップライト14は、ガラス板28の周縁に枠体22による外縁(額縁)が形成され、外縁内に照射される太陽光等が、ガラス板28及び採光板30を透過することで、屋内への採光が可能にされている。したがって、建物の屋内は、トップライト14から太陽光が採光される。 As a result, the top light 14 has an outer edge (picture frame) formed by the frame 22 around the periphery of the glass plate 28, and the sunlight or the like irradiated into the outer edge passes through the glass plate 28 and the lighting plate 30. Allows daylighting into the interior. Therefore, sunlight is received from the top light 14 inside the building.

〔遮光構造〕
ここで、本実施形態では、既存屋根の改修工事を例として、トップライト14を遮光することで、屋内への太陽光の採光を抑制する。図1には、本実施形態に適用した架台40の主要部が斜視図にて示されている。
[Light shielding structure]
Here, in the present embodiment, taking repair work of an existing roof as an example, the skylight 14 is shaded to suppress sunlight from entering the building. FIG. 1 shows a perspective view of a main portion of a pedestal 40 applied to this embodiment.

図1に示すように、本実施形態に係る架台40には、一例として2本の架台部材42が用いられている。架台部材42は、支柱部44及び桟部46を備えている。架台部材42の桟部46は、所定長さの等辺山形鋼(アングル材)が用いられている。桟部46は、一方の外面が支持面48とされ、他方の外面が調整面50とされており、桟部46は、支持面48と調整面50とが互いの幅方向の一端側が連結されて長手方向視断面が略L字形状に形成されている。 As shown in FIG. 1, two gantry members 42 are used for the gantry 40 according to the present embodiment, as an example. The gantry member 42 includes a strut portion 44 and a crosspiece portion 46 . A crosspiece 46 of the frame member 42 is made of equal-angle steel (angle material) having a predetermined length. One outer surface of the crosspiece 46 serves as a support surface 48 and the other outer surface serves as an adjustment surface 50 . The cross section in the longitudinal direction is substantially L-shaped.

桟部46の調整面50には、長孔部としての長孔52が貫通形成されており、長孔52は、調整面50の幅方向の中間部において、長軸方向が調整面50の長手方向に沿って形成されている。これにより、2本の桟部46は、互いの支持面48が面一となるように調整面50を対向されることで、各々の調整面50の長孔52の少なくとも一部が重なりあうことが可能になっている。 A long hole 52 as a long hole portion is formed through the adjustment surface 50 of the beam portion 46 . formed along the direction As a result, the adjustment surfaces 50 of the two crosspieces 46 face each other so that the support surfaces 48 are flush with each other, so that at least parts of the long holes 52 of the adjustment surfaces 50 overlap each other. is possible.

支柱部44は、長手方向の一端側に取付部54が形成されており、取付部54は、側方視が矩形枠状に形成され、支柱部44の桟部46側に突設されている。このような支柱部44は、例えば、鋼板製の帯状板材が用いられ、帯状板材の長手方向の一端側が矩形枠状に曲げ加工することで容易に作成できる。例えば、支柱部44には、桟部46の支持面48の幅寸法よりも広幅の帯状板材が用いられ、帯状板材の一端部を略コ字状に折曲(曲げ加工)し、さらに折曲先端側が内側に折り曲げられることで断面が上下方向(支柱部44の長手方向)に長い矩形略枠状に形成される。 A mounting portion 54 is formed on one end side of the support portion 44 in the longitudinal direction. The mounting portion 54 is formed in a rectangular frame shape when viewed from the side, and protrudes from the support portion 44 toward the crosspiece portion 46 side. . For example, a band-shaped plate made of steel plate is used for such a column portion 44, and one end side in the longitudinal direction of the band-shaped plate can be easily formed by bending into a rectangular frame shape. For example, the strut portion 44 uses a strip-shaped plate material having a width larger than the width dimension of the support surface 48 of the crosspiece portion 46, and one end portion of the strip-shaped plate material is bent (bent) into a substantially U-shape, and further bent. By bending the tip side inward, the cross section is formed into a substantially rectangular frame shape elongated in the vertical direction (longitudinal direction of the support 44).

支柱部44は、取付部54の先端面(長手方向側の面)が取付面54Aとされ、取付部54の下側(取付面54Aとは反対側)の面が当接面54Bとされている。支柱部44は、桟部46の長手方向の一端側において、取付部54の取付面54Aが桟部46の支持面48とは反対側の面(支持面48の裏側の面)に当接され、取付部54の側部に桟部46の調整面50とは反対側の面が当接されて、桟部46が溶接等により接合されている。これにより、架台部材42は、側方(例えば調整面50側)から見て、支柱部44と桟部46とが略直角となるように接合されて、略L形状に形成されている。また、支柱部44の取付部54は、当接面54Bが桟部46の調整面50の幅方向外側、すなわち、桟部46より支持面48とは反対側に突設されている。 The post portion 44 has a mounting surface 54A on the front end surface (a surface on the longitudinal side) of the mounting portion 54, and a contact surface 54B on the lower side of the mounting portion 54 (the side opposite to the mounting surface 54A). there is At one end of the crosspiece 46 in the longitudinal direction, the mounting surface 54A of the support 44 abuts against the surface of the crosspiece 46 opposite to the support surface 48 (the surface on the back side of the support surface 48). The surface of the beam portion 46 opposite to the adjustment surface 50 is brought into contact with the side portion of the mounting portion 54, and the beam portion 46 is joined by welding or the like. As a result, when viewed from the side (for example, from the side of the adjustment surface 50), the pedestal member 42 is formed in a substantially L shape by joining the strut part 44 and the crosspiece part 46 so as to form a substantially right angle. Further, the mounting portion 54 of the strut portion 44 has a contact surface 54B projecting from the width direction outside of the adjustment surface 50 of the crosspiece portion 46 , that is, on the opposite side of the support surface 48 from the crosspiece portion 46 .

架台40は、2つの架台部材42の一方を反転させて、互いの支柱部44が離間されると共に、桟部46の先端側が互い他方に向けられて配置され、互いの桟部46の調整面50同士が対向される。これにより、架台40は、2本が一体にされた桟部46の長手方向の両側に支柱部44が対で配置され、調整面50同士を桟部46の長手方向に相対移動することで、一対の支柱部44の間隔が変更可能になっている。また、架台40は、調整面50の各々の長孔52に少なくとも2本のボルト56が挿入されて、ボルト56の各々にナット58が螺合されることで、桟部46同士を締結固定することで、一対の架台部材42が連結される。なお、2つの架台部材42は、例えば、桟部46の長さが異なってもよい。 The pedestal 40 is arranged by reversing one of the two pedestal members 42 so that the strut portions 44 are separated from each other, and the leading end sides of the crosspiece portions 46 are directed toward the other. 50 are opposed to each other. As a result, the pedestal 40 has a pair of struts 44 arranged on both sides in the longitudinal direction of the crosspieces 46, which are two integrated pieces, and the adjustment surfaces 50 are relatively moved in the longitudinal direction of the crosspieces 46. The interval between the pair of struts 44 is changeable. At least two bolts 56 are inserted into each long hole 52 of the adjustment surface 50 of the mount 40, and nuts 58 are screwed to each of the bolts 56, thereby fastening and fixing the crosspieces 46 to each other. Thus, the pair of gantry members 42 are connected. Note that the two frame members 42 may have crosspieces 46 with different lengths, for example.

架台40は、一対の支柱部44がトップライト14の幅方向の両側にされて、桟部46がトップライト14を跨ぐように配置される。また、架台40は、支柱部44の各々がトップライト14の枠体22(外枠26)に当接されるように、桟部46同士の重なり代が調整され桟部46全体の長さが調整されて、一対の支柱部44の間隔が調整される。 The pedestal 40 is arranged so that a pair of strut portions 44 are provided on both sides of the skylight 14 in the width direction, and a crosspiece portion 46 straddles the skylight 14 . In addition, in the frame 40, the overlap between the crosspieces 46 is adjusted so that each of the struts 44 abuts against the frame 22 (outer frame 26) of the skylight 14, and the overall length of the crosspieces 46 is adjusted. By adjusting, the spacing between the pair of support columns 44 is adjusted.

一対の支柱部44の間隔が調整された架台40は、支柱部44の取付部54の当接面54Bが外枠26の嵌合Bの上面(トップライト14の周縁)に当接されて枠体22上に配置され、支柱部44の各々が例えばネジ60等が用いられて枠体22(例えば内枠24)に締結固定される。これにより、架台40は、桟部46の支持面48が上方に向けられた状態で枠体22に固定されて設置される。また、支柱部44の取付部54における当接面54Bが、調整面50の幅方向外側に突出されているので、架台40は、桟部46が枠体22及びガラス板28に干渉するのが防止される。なお、内枠24と外枠26との間に段差がある場合には、支柱部44に内枠24に向けて凸となる窪み部44Aを形成し、窪み部44Aにおいてネジ60を螺合することが好ましい。 The mounting frame 40, in which the spacing between the pair of support columns 44 is adjusted, is configured such that the contact surfaces 54B of the attachment portions 54 of the support columns 44 are brought into contact with the upper surface of the fitting B of the outer frame 26 (peripheral edge of the top light 14). It is arranged on the body 22, and each of the struts 44 is fastened and fixed to the frame body 22 (eg, the inner frame 24) using screws 60 or the like. As a result, the mount 40 is fixed to the frame 22 and installed with the support surface 48 of the crosspiece 46 facing upward. In addition, since the contact surface 54B of the mounting portion 54 of the support 44 protrudes outward in the width direction of the adjustment surface 50, the frame 22 and the glass plate 28 are prevented from interfering with each other. prevented. If there is a step between the inner frame 24 and the outer frame 26, the support 44 is formed with a concave portion 44A that protrudes toward the inner frame 24, and the screw 60 is screwed into the concave portion 44A. is preferred.

また、架台40は、トップライト14の長手方向に所定間隔で固定されて複数が枠体22に取り付けられて配置される。架台40の取り付け間隔は、枠体22の幅寸法、及び下記遮光屋根パネル62の重さ等に応じて設定されるものであればよい。 The mounts 40 are fixed at predetermined intervals in the longitudinal direction of the skylight 14, and a plurality of mounts 40 are attached to the frame 22 and arranged. The mounting interval of the pedestal 40 may be set according to the width dimension of the frame 22, the weight of the light-shielding roof panel 62 described below, and the like.

本実施形態の遮光構造では、遮光用屋根材料としての遮光屋根パネル62が用いられ、遮光屋根パネル62が複数の架台40に跨って載置される。遮光屋根パネル62には、切断が可能であると共に、幅方向及び長さ方向に複数が連結可能な一般的市販品を用いることが好ましい。また、遮光屋根パネル62は、表面にZAM(溶融亜鉛-アルミニウム-マグネシウム合金めっき鋼板の登録商標)や溶融亜鉛めっき処理した材料などの風雨に耐え得る部材が用いられていることが好ましい。これにより、遮光屋根パネル62は、設置面積の変更が容易、かつ耐候性に優れる。 In the light-shielding structure of this embodiment, a light-shielding roof panel 62 is used as a light-shielding roof material, and the light-shielding roof panel 62 is placed across a plurality of frames 40 . For the light-shielding roof panel 62, it is preferable to use a general commercial product that can be cut and can be connected in the width direction and the length direction. Moreover, it is preferable that the light-shielding roof panel 62 is made of a material that can withstand wind and rain, such as ZAM (a registered trademark of hot-dip zinc-aluminum-magnesium alloy-plated steel sheet) or a hot-dip galvanized material. As a result, the light-shielding roof panel 62 can easily change the installation area and has excellent weather resistance.

遮光屋根パネル62は、表板64と裏板66との間に断熱材68が配置されている。また、遮光屋根パネル62には、表板64に略台形状の凸部64Aが幅方向に所定間隔で形成され、裏板66に各々が略台形状の凹部66Aが形成されており、凹部66Aの各々が凸部64Aの各々の下側に形成されている。なお、遮光屋根パネル62の表面形状は、屋根10の屋根材の形状を考慮した形状であることが好ましく、これにより、遮光屋根パネル62が屋根10の美観を損ねるのを抑制できる。 The light-shielding roof panel 62 has a heat insulating material 68 disposed between a top plate 64 and a back plate 66 . Further, in the light-shielding roof panel 62, substantially trapezoidal protrusions 64A are formed on the front plate 64 at predetermined intervals in the width direction, and substantially trapezoidal recesses 66A are formed on the back plate 66, respectively. are formed below each of the protrusions 64A. The surface shape of the light-shielding roof panel 62 is preferably a shape that takes into account the shape of the roof material of the roof 10 .

遮光屋根パネル62は、長手方向(凸部64Aの配列方向とは交差する方向)が折板12の長手方向とされて屋根10上に設置される。また、遮光屋根パネル62は、トップライト14の枠体22を覆いかつ架台40の各々を一体で覆う大きさ(周縁部が枠体22の外側に突出する大きさ、設置面積)とされ、複数の架台40の各々に跨って配置される。 The light-shielding roof panel 62 is installed on the roof 10 with the longitudinal direction (the direction intersecting the arrangement direction of the convex portions 64A) being the longitudinal direction of the folded plate 12. As shown in FIG. The light-shielding roof panel 62 is sized to cover the frame 22 of the skylight 14 and integrally cover each of the pedestals 40 (the size of the peripheral portion protruding outside the frame 22, installation area). , straddling each of the pedestals 40.

遮光屋根パネル62は、裏板66が桟部46の支持面48に当接されて架台40に支持される。また、遮光屋根パネル62は、凸部64Aから挿入されて、凹部66Aに貫通した取付ネジ60Aが支持面48から桟部46に螺合されることで、架台40の各々に締結固定される。これにより、遮光屋根パネル62は、トップライト14の上方を覆い、トップライト14のガラス板28に太陽光が照射されるのを抑制し、トップライト14から建物の屋内に太陽の光が差込んでしまうのを抑制する。 The light-shielding roof panel 62 is supported by the pedestal 40 with the back plate 66 in contact with the support surface 48 of the crosspiece 46 . Also, the light-shielding roof panel 62 is fastened and fixed to each of the frames 40 by inserting from the convex portion 64A and screwing the mounting screw 60A penetrating the concave portion 66A into the crosspiece portion 46 from the support surface 48 . As a result, the light-shielding roof panel 62 covers the top of the top light 14, suppresses the sunlight from irradiating the glass plate 28 of the top light 14, and allows sunlight to enter the interior of the building from the top light 14. to prevent it from falling out.

このように構成されている本実施形態では、架台40に2つの架台部材42が用いられている。架台部材42は、支柱部44と桟部46によって略L字形状とされた簡単な形状とされているので低コストで容易に作製できる。また、2つの架台部材42は、桟部46の調整面50を対向させた状態で調整面50を桟部46の長手方向に相対移動することで、一対の支柱部44の間隔を調整できる。また、架台部材42は、桟部46の調整面50に長孔52が形成されているので、2つの架台部材42は、長手方向の任意の位置においてボルト56及びナット58によって簡単に締結固定して接合できる。 In this embodiment configured as described above, two gantry members 42 are used for the gantry 40 . The pedestal member 42 has a simple shape in which the strut portion 44 and the crosspiece portion 46 are substantially L-shaped, so that it can be easily manufactured at a low cost. In addition, the two mount members 42 can adjust the distance between the pair of struts 44 by relatively moving the adjustment surfaces 50 of the crosspieces 46 in the longitudinal direction while the adjustment surfaces 50 of the crosspieces 46 face each other. In addition, since the mounting member 42 has the long hole 52 formed in the adjustment surface 50 of the cross piece 46, the two mounting members 42 can be easily fastened and fixed at any position in the longitudinal direction using the bolts 56 and the nuts 58. can be spliced together.

一般に、トップライト14を遮光するための遮光用屋根材を取り付けるための架台を作製するためには、予め店舗を訪問して屋根10に上がり、トップライト14の採寸を行なう必要がある。また、架台は、採寸結果に基づいて精度よく作製する必要がある。 In general, in order to manufacture a frame for attaching a light-shielding roof material for shielding the skylight 14, it is necessary to visit the store in advance, climb the roof 10, and measure the skylight 14. - 特許庁In addition, the pedestal must be manufactured with high accuracy based on the measurement results.

これに対して、架台40では、2つの架台部材42を用いることで、所謂現場合わせで一対の支柱部44の間隔を調整できるので、予めトップライト14の採寸作業を行なう必要がない。このため、作業に先立って店舗を訪問し、屋根10に上がっての採寸などの作業を行なう必要がなくなり、作業工数を削減できる。しかも、架台40に用いる架台部材42は、支柱部44と桟部46を接合した簡単な構造であるので、容易に作製できる。 On the other hand, in the mount frame 40, the two mount members 42 are used so that the spacing between the pair of support columns 44 can be adjusted by so-called on-site adjustment, so there is no need to measure the skylight 14 in advance. For this reason, it is not necessary to visit the store prior to the work and perform work such as going up to the roof 10 to take measurements, thereby reducing man-hours for work. Moreover, since the gantry member 42 used for the gantry 40 has a simple structure in which the strut portion 44 and the crosspiece portion 46 are joined together, it can be easily manufactured.

また、架台40の設置及び遮光屋根パネル62の取り付けは、店舗の屋根10上での作業のみであるので、店舗内に陳列されている商品等を移動するなどの養生を行なう必要がないので、トップライト14の遮光のための作業が店舗の営業に影響を及ぼすことがない。しかも、トップライト14からの太陽光が遮られるので、店舗内の商品が熱や太陽光の影響を受けて損傷等が生じるのを防止できると共に、店舗内の空調効率の低下を抑制できる。 In addition, since the installation of the pedestal 40 and the installation of the light-shielding roof panel 62 are performed only on the roof 10 of the store, there is no need to carry out curing such as moving the products displayed in the store. The work for blocking light from the top light 14 does not affect the business of the store. Moreover, since the sunlight from the top light 14 is blocked, it is possible to prevent the products in the store from being damaged by the influence of heat and sunlight, and to suppress the deterioration of the air-conditioning efficiency in the store.

さらに、架台40の支柱部44は、取付部54の下面の当接面54Bがトップライト14の枠体22に当接されるので、トップライト14の枠体22に対して、遮光屋根パネル62を容易に位置決めできる。これにより、トップライト14(ガラス板28)と遮光屋根パネル62との間隔調整を容易になるので、屋根10に対する適正な位置への遮光屋根パネル62の取り付けが容易になる。しかも、架台部材42は、支柱部44の取付部54における当接面54Bが、桟部46の下側に突出されている。このため、架台40は、架台部材42は勿論、遮光屋根パネル62がトップライト14のガラス板28から離間されるので、架台部材42等がガラス板28に接触して損傷等を生じさせてしまうのを効果的に防止できる。 Furthermore, since the contact surface 54B of the lower surface of the mounting portion 54 of the support column 44 of the mount frame 40 contacts the frame 22 of the top light 14, the light shielding roof panel 62 is positioned against the frame 22 of the top light 14. can be easily positioned. This facilitates the adjustment of the distance between the skylight 14 (the glass plate 28 ) and the light shielding roof panel 62 , thereby facilitating the attachment of the light shielding roof panel 62 to an appropriate position on the roof 10 . Moreover, in the mounting member 42 , the abutment surface 54</b>B of the mounting portion 54 of the strut portion 44 protrudes below the rail portion 46 . As a result, the gantry member 42 and the light-shielding roof panel 62 are separated from the glass plate 28 of the skylight 14, so that the gantry member 42 and the like come into contact with the glass plate 28 and cause damage. can be effectively prevented.

また、架台40及び遮光屋根パネル62の設置の際、既存のトップライト14の枠体22等の解体や改修(改造)等を行なうことがないので、屋内から見たトップライト14の外観を維持できると共に、作業コストの低減を図ることができる。しかも、既存の防水機能を利用できて、遮光屋根パネル62の取り付け作業及び防水処理が容易になる。 In addition, when installing the frame 40 and the light-shielding roof panel 62, there is no need to dismantle or modify (modify) the frame 22 of the existing top light 14, so that the appearance of the top light 14 as seen from the inside is maintained. In addition, it is possible to reduce the working cost. Moreover, the existing waterproof function can be used, and the installation work and waterproof treatment of the light shielding roof panel 62 are facilitated.

また、遮光屋根パネル62に断熱材68を設けているので、遮光屋根パネル62が太陽光の熱を受けても、遮光屋根パネル62の熱がトップライト14から屋内に伝達されるのを抑制できて、断熱性をより向上できる。これにより、屋内の空調効率の低下をより抑制できる。さらに、架台40は、桟部46の長手方向両側の支柱部44の下端部のみが枠体22に固定されている。このため、遮光屋根パネル62を架台40の各々から外して、架台40の支柱部44の各々を枠体22から取り外す簡単な作業で、屋根10上においてトップライト14を再現できて、屋内の採光が可能になる。 Further, since the heat insulating material 68 is provided on the light-shielding roof panel 62, even if the light-shielding roof panel 62 receives the heat of the sunlight, the heat of the light-shielding roof panel 62 can be suppressed from being transmitted from the skylight 14 to the interior. , the heat insulation can be further improved. As a result, it is possible to further suppress a decrease in indoor air-conditioning efficiency. Further, the mount 40 is fixed to the frame 22 only at the lower end portions of the strut portions 44 on both sides in the longitudinal direction of the crosspiece portion 46 . Therefore, the top light 14 can be reproduced on the roof 10 by a simple work of removing the light-shielding roof panel 62 from each of the mounts 40 and removing each of the struts 44 of the mounts 40 from the frame 22, and lighting of the room can be achieved. becomes possible.

なお、以上説明した本実施形態では、屋根10において平面視矩形状に形成されたトップライト14を例に説明した。しかしながら、採光部は、平面視矩形状に限らず、L字形状や、矩形状を周回するように繋げた形状であってもよい。 In addition, in this embodiment described above, the skylight 14 formed in a rectangular shape in a plan view on the roof 10 has been described as an example. However, the light-receiving part is not limited to a rectangular shape in plan view, and may be an L shape or a shape in which rectangular shapes are connected so as to go around.

図5には、本実施形態の採光部の変形例としてのトップライト70の概略が平面図にて示されている。
図5に示すようにトップライト70は、各々が矩形状に形成されたトップライト部(トップライト)72とトップライト部(トップライト)74とが連続された形状にされている。トップライト70の枠体76は、トップライト部72の枠体72Aとトップライト部74の枠体74Aとが各々の長手方向の一側において連結されて一体にされた形状にされている。これにより、トップライト70は、平面視略L字状に形成されている。
FIG. 5 shows a schematic plan view of a skylight 70 as a modified example of the lighting section of the present embodiment.
As shown in FIG. 5, the top light 70 has a shape in which a top light portion (top light) 72 and a top light portion (top light) 74 each having a rectangular shape are connected. A frame 76 of the top light 70 is formed in a shape in which a frame 72A of the top light portion 72 and a frame 74A of the top light portion 74 are connected on one side in the longitudinal direction to be integrated. Thereby, the top light 70 is formed in a substantially L shape in a plan view.

架台40は、トップライト部72側において枠体72Aの幅方向に架け渡されると共に、複数がトップライト部72の枠体72Aの長手方向に配置されている。また、架台40は、トップライト部74側において枠体74Aの幅方向に架け渡されると共に、複数がトップライト部74の枠体74Aの長手方向に配置されている。 The pedestals 40 span the width direction of the frame 72A on the side of the top light portion 72, and a plurality of the pedestals 40 are arranged in the longitudinal direction of the frame 72A of the top light portion 72. As shown in FIG. In addition, the pedestals 40 span the width direction of the frame 74A on the side of the top light portion 74, and a plurality of the pedestals 40 are arranged in the longitudinal direction of the frame 74A of the top light portion 74. As shown in FIG.

遮光屋根パネル62は、複数が長手方向及び幅方向に連結されて平面視略L字状にされ、トップライト部72側の架台40及びトップライト部74側の架台40に跨って配置されて、架台40の各々に固定されて設置されている。 A plurality of light-shielding roof panels 62 are connected in the longitudinal direction and the width direction to form a substantially L-shape in plan view, and are arranged across the mount 40 on the side of the top light part 72 and the mount 40 on the side of the top light part 74, It is fixed and installed on each of the pedestals 40 .

このようなトップライト70においても、トップライト14と同様の架台40(架台部材42)を用いて容易に遮光できる。また、遮光作業において屋内での作業が不要であるので、トップライト70の遮光のための作業が店舗の営業等に影響を及ぼすことがない。 In such a top light 70 as well, light can be easily shielded by using the mount 40 (mount member 42) similar to that of the top light 14. As shown in FIG. In addition, since it is not necessary to work indoors for the light blocking work, the light blocking work for the skylight 70 does not affect the business of the store.
