図１に示すように、採光用構造体１は、例えば工場２０の屋根３０に設置して用いることができる。 As shown in FIG. 1, the lighting structure 1 can be installed and used on, for example, a roof 30 of a factory 20.

まず、採光用構造体１について説明する前に、屋根３０について説明する。
屋根３０は、全体として、水平となっていてもよいが、壁際部３０１から軒先３０２に向かって傾斜しているのが好ましい。なお、屋根３０が傾斜している場合、その傾斜の程度（斜度）としては、特に限定されず、例えば、３％程度が好ましい。 First, the roof 30 will be described before describing the lighting structure 1.
Although the roof 30 may be horizontal as a whole, it is preferable to incline from the wall portion 301 toward the eaves 302. In addition, when the roof 30 inclines, it does not specifically limit as a grade (inclination degree) of the inclination, For example, about 3% is preferable.

例えば図４〜図８に示すように、屋根３０は、山状に突出し（隆起し）、ｘ方向に沿って延在する凸条（屋根側凸条）３０３を複数有している。そして、これらの凸条３０３は、ｙ方向に沿って等間隔に配置されている。これにより、屋根３０は、全体として波形をなすものとなる。また、各凸条３０３のｙ方向の両側には、それぞれ、傾斜面３０５を有している。 For example, as shown in FIG. 4 to FIG. 8, the roof 30 has a plurality of ridges (a roof side ridge) 303 protruding (raised) in a mountain shape and extending along the x direction. And these convex lines 303 are arrange | positioned at equal intervals along ay direction. As a result, the roof 30 is corrugated as a whole. In addition, sloped surfaces 305 are respectively provided on both sides in the y direction of each of the ridges 303.

また、ｘ方向に隣接する凸条３０３同士間の部分は、溝３０４となっている。この溝３０４の底部３０６は、平面となっており、屋根３０の傾斜方向下方に向かって雨水等が流れることができる。これにより、屋根３０は、水はけがよいものとなる。 Further, a portion between the ridges 303 adjacent to each other in the x direction is a groove 304. The bottom portion 306 of the groove 304 is flat, and rainwater and the like can flow downward in the inclination direction of the roof 30. This makes the roof 30 drainable.

このような波形をなす屋根３０は、長尺状をなす金属板を幅方向に所定箇所折り曲げて、当該折り曲げられた金属板同士を組み合わせた構成となっている。このような屋根３０を一般的に「ハゼ式折板屋根」と言うことがある。 Such a corrugated roof 30 has a configuration in which a long metal plate is bent at a predetermined position in the width direction, and the bent metal plates are combined. Such a roof 30 may be generally referred to as a "folded roof".

例えば、図３に示すように、屋根３０には、開口部３０７が形成されている。開口部３０７は、複数の凸条３０３をうちの任意の２つの凸条３０３の頂部３０８同士の間の部分を開口して、すなわち、欠損して形成されている。そして、屋根３０の開口部３０７には、採光用構造体１が設置されている。 For example, as shown in FIG. 3, an opening 307 is formed in the roof 30. The opening 307 is formed by opening a portion between the top portions 308 of any two of the ridges 303 among the plurality of ridges 303, that is, by forming a defect. The lighting structure 1 is installed in the opening 307 of the roof 30.

なお、前記任意の２つの凸条３０３は、開口部３０７の大きさに応じて、第１の凸条（第１の屋根側凸条）３０３Ａと、第１の凸条３０３Ａと異なる位置にある第２の凸条（第２の屋根側凸条）３０３Ｂとして、適宜選択される。 Note that the two arbitrary ridges 303 are at positions different from the first ridge (the first roof-side ridge) 303A and the first ridge 303A according to the size of the opening 307. It is suitably selected as the 2nd convex streak (the 2nd roof side convex streak) 303B.

次に、採光用構造体１について説明する。
図８に示すように、採光用構造体１は、屋外の光、すなわち、自然光ＮＬを屋内４０（工場２０内）に採り入れるものである。 Next, the lighting structure 1 will be described.
As shown in FIG. 8, the structure for light collection 1 is to introduce outdoor light, that is, natural light NL into the indoor 40 (in the factory 20).

図３、図８に示すように、採光用構造体１は、採光部材２と、縦梁（縦下地）３とを備えている。また、この採光用構造体１を横梁（横下地）４が支持している。 As shown in FIGS. 3 and 8, the structure for light collection 1 includes a light collection member 2 and a longitudinal beam (vertical base) 3. In addition, a cross beam (horizontal base) 4 supports the lighting structure 1.

図２に示すように、採光部材２は、屋根３０の開口部３０７を覆うように配置されている。これにより、採光部材２を透過した自然光ＮＬを屋内４０に十分に採り込むことができる。 As shown in FIG. 2, the light collecting member 2 is disposed to cover the opening 307 of the roof 30. Thereby, natural light NL transmitted through the light collecting member 2 can be sufficiently taken into the room 40.

採光部材２は、自然光ＮＬが透過する程度の光透過性を有する樹脂材料で構成され、このような材料としては、特に限定されないが、例えば、ポリカーボネートが好ましい。なお、採光部材２は、透明なものであってもよいし、半透明なものであってもよいが、自然光ＮＬの透過率が５％以上、９５％以下であるのが好ましく、２０％以上、９０％以下であるのがより好ましい。また、採光部材２は、無色のものであってもよいし、有色のものであってもよい。 The light collecting member 2 is made of a resin material having light transmittance to the extent that natural light NL is transmitted, and such a material is not particularly limited, but, for example, polycarbonate is preferable. The daylighting member 2 may be transparent or semitransparent, but the transmittance of natural light NL is preferably 5% or more and 95% or less, and is preferably 20% or more. And 90% or less is more preferable. Moreover, the light collecting member 2 may be colorless or colored.

採光部材２は、山状に突出し（隆起し）、ｘ方向に沿って延在する凸条２１を複数（本実施形態では４つ）有している。そして、これらの凸条２１は、ｙ方向に沿って等間隔に配置されている。これにより、採光部材２は、全体として波形をなすものとなる。なお、ｙ方向に隣り合う凸条２１同士のピッチは、ｙ方向に隣り合う凸条３０３同士のピッチと同じである。これにより、屋根３０は、採光部材２を含んだ全体として、前記波形が揃った状態となり、よって、見栄えがよいものとなる。 The daylighting member 2 has a plurality of (four in the present embodiment) convex ridges 21 protruding (raised) in a mountain shape and extending along the x direction. And these convex lines 21 are arrange | positioned at equal intervals along ay direction. Thus, the light collecting member 2 has a waveform as a whole. The pitch of the ridges 21 adjacent to each other in the y direction is the same as the pitch of the ridges 303 adjacent to each other in the y direction. As a result, the roof 30 is in a state in which the above-mentioned corrugations are aligned as a whole including the light collecting member 2, and hence the roof 30 has a good appearance.

なお、採光部材２が有する凸条２１の形成数は、本実施形態では４つであるが、これに限定されず、開口部３０７の大きさ等の各種諸条件によっては、例えば、１つ、２つ、３つまたは５つ以上であってもよい。また、本実施形態では開口部３０７を１枚の採光部材２で覆っているが、これに限定されず、例えば、２枚以上の採光部材２で覆ってもよい。 In the present embodiment, the number of formations of the ridges 21 of the light collecting member 2 is four, but is not limited to this. Depending on various conditions such as the size of the opening 307, for example, one. There may be two, three or five or more. Moreover, although the opening part 307 is covered by one light collecting member 2 in this embodiment, it is not limited to this, For example, you may cover by two or more light collecting members 2. FIG.

図８に示すように、複数の凸条２１のうちの、ｙ方向の最も負側（図８中の最も左側）に位置する第１の凸条２１Ａは、採光部材２が開口部３０７を覆うように配置された際、屋根３０の第１の凸条３０３Ａに上側から重なって係合する。一方、複数の凸条２１のうちの、ｙ方向の最も正側（図８中の最も右側）に位置する第２の凸条２１Ｂは、採光部材２が開口部３０７を覆うように配置された際、屋根３０の第２の凸条３０３Ｂに上側から重なって係合する。また、第１の凸条２１Ａと第２の凸条２１Ｂとの間の各凸条２１も、第１の凸条３０３Ａと第２の凸条３０３Ｂとの間の各凸条３０３に上側から重なって係合するのが好ましい。 As shown in FIG. 8, of the plurality of ridges 21, the first ridge 21A positioned on the most negative side (the leftmost in FIG. 8) in the y direction has the light collecting member 2 covering the opening 307. When arranged in such a manner, the first ridges 303A of the roof 30 overlap and engage from above. On the other hand, of the plurality of ridges 21, the second ridge 21B positioned on the most positive side in the y direction (the rightmost in FIG. 8) is arranged such that the light collecting member 2 covers the opening 307. At the same time, the second ridge 303B of the roof 30 is engaged from the upper side in an overlapping manner. Further, each of the ridges 21 between the first ridge 21A and the second ridge 21B also overlaps the ridge 303 between the first ridge 303A and the second ridge 303B from the upper side. Preferably engaged.

凸条２１のｙ方向の両側面は、それぞれ、傾斜面２１１となっている。傾斜面２１１同士がなす角度は、各凸条３０３における傾斜面３０５同士のなす角度と同じであってもよいし、異なっていてもよい。 The side surfaces in the y direction of the ridges 21 are inclined surfaces 211, respectively. The angle formed by the inclined surfaces 211 may be the same as or different from the angle formed by the inclined surfaces 305 in the respective ridges 303.

また、図７に示すように、凸条２１の平坦な頂部２１２には、貫通孔２１３が貫通して形成されている。この貫通孔２１３には、後述する固定部５のボルト５１が挿通する。 Further, as shown in FIG. 7, a through hole 213 is formed through the flat top portion 212 of the ridge 21. The bolt 51 of the fixing portion 5 described later is inserted into the through hole 213.

ｘ方向に隣接する凸条２１同士間の部分は、溝２２となっている。この溝２２の底部２２１は、平面となっており、屋根３０の傾斜方向下方に向かって雨水等が流れることができる。これにより、屋根３０は、水はけがよいものとなる。 A portion between the ridges 21 adjacent to each other in the x direction is a groove 22. The bottom 221 of the groove 22 is flat, and rainwater and the like can flow downward in the inclination direction of the roof 30. This makes the roof 30 drainable.

図２、図３、図８に示すように、縦梁３は、採光部材２をその下方から支持する梁である。縦梁３は、ｘ方向に沿って延在している。本実施形態では、縦梁３は、２本設置されている。これらの縦梁３は、ｙ方向に間隔を置いて配置されている。この間隔（ピッチ）は、ｙ方向に隣り合う凸条２１同士のピッチと同じである。そして、図８に示すように、各縦梁３は、第１の凸条２１Ａと第２の凸条２１Ｂとの間にある各凸条２１の頂部２１２の裏側を支持している。このような縦梁３が設置されていることにより、屋根３０の採光用の開口部３０７の大きさに関わらず、例えば、当該開口部３０７を覆う採光部材２の自重による撓みを確実に防止することができる。また、採光部材２の脱落や座屈等を防ぎ、積雪荷重や風圧力に対する耐荷重性を向上させることができる。 As shown in FIG. 2, FIG. 3 and FIG. 8, the vertical beam 3 is a beam that supports the light collecting member 2 from below. The longitudinal beam 3 extends along the x direction. In the present embodiment, two vertical beams 3 are provided. These longitudinal beams 3 are arranged at intervals in the y direction. The interval (pitch) is the same as the pitch of the ridges 21 adjacent to each other in the y direction. And as shown in FIG. 8, each vertical beam 3 supports the back side of the top 212 of each ridge 21 between the first ridge 21A and the second ridge 21B. By installing such a longitudinal beam 3, regardless of the size of the opening 307 for daylighting of the roof 30, for example, the deflection of the daylighting member 2 covering the opening 307 due to its own weight is reliably prevented. be able to. In addition, it is possible to prevent dropout, buckling, and the like of the daylighting member 2 and to improve load resistance to snow load and wind pressure.

なお、縦梁３の設置本数は、本実施形態では２本であるが、これに限定されず、例えば、開口部３０７の大きさ、採光部材２の重量等の各種諸条件によっては、１本または３本以上としてもよい。 The number of vertical beams 3 installed is two in the present embodiment, but is not limited to this. For example, depending on various conditions such as the size of the opening 307 and the weight of the light collecting member 2 Or it may be three or more.

図９に示すように、縦梁３は、第１板状部３１１と、第２板状部３１２と、第２板状部３１３とを有する構造のものとなっている。第１板状部３１１、第２板状部３１２および第２板状部３１３は、いずれも、ｘ方向に沿った長尺な板状をなす部分である。第１板状部３１１は、その厚さ方向がｙ方向と平行となっている。第２板状部３１２は、第１板状部３１１に対して、ｚ方向正側に位置しており、ｙ方向正側に突出している。一方、第２板状部３１３は、第１板状部３１１に対して、ｚ方向負側に位置しており、ｙ方向正側に突出している。また、第２板状部３１２および第２板状部３１３は、それぞれ、その幅方向がｙ方向と平行となっている。このような構造の縦梁３は、板部材を所定箇所で直角に折り曲げて、第１板状部３１１と、第２板状部３１２と、第２板状部３１３とを形成してなるものである。これにより、縦梁３自身の剛性が向上し、よって、採光部材２を十分に支持して、採光部材２の撓み等をより確実に防止することができる。また、例えば、降雪により採光部材２が積雪状態となったとしても、採光部材２が雪の重量により撓むのを防止することができる。 As shown in FIG. 9, the longitudinal beam 3 has a structure including a first plate-like portion 311, a second plate-like portion 312, and a second plate-like portion 313. Each of the first plate-like portion 311, the second plate-like portion 312, and the second plate-like portion 313 is a long plate-like portion along the x direction. The thickness direction of the first plate-like portion 311 is parallel to the y-direction. The second plate-like portion 312 is located on the z-direction positive side with respect to the first plate-like portion 311, and protrudes on the y-direction positive side. On the other hand, the second plate-like portion 313 is located on the z-direction negative side with respect to the first plate-like portion 311, and protrudes on the y-direction positive side. Further, the width direction of each of the second plate-like portion 312 and the second plate-like portion 313 is parallel to the y-direction. The longitudinal beam 3 having such a structure is formed by bending a plate member at a predetermined position at a right angle to form a first plate-like portion 311, a second plate-like portion 312, and a second plate-like portion 313. It is. As a result, the rigidity of the longitudinal beam 3 itself is improved, so that the light collecting member 2 can be sufficiently supported, and the deflection of the light collecting member 2 can be more reliably prevented. In addition, for example, even if the light collecting member 2 is put into the snow accumulation state due to snowfall, it is possible to prevent the light collecting member 2 from being bent by the weight of the snow.

なお、縦梁３は、例えば、鉄製のものである。この場合、縦梁３の表面には、例えば、防錆めっき等の表面処理が施されているのが好ましい。 The longitudinal beam 3 is made of iron, for example. In this case, the surface of the longitudinal beam 3 is preferably subjected to surface treatment such as anticorrosion plating, for example.

図３、図８に示すように、横梁４は、縦梁３を採光部材２ごと、その下方から支持する梁である。横梁４は、ｙ方向に沿って延在している。図３、図１０に示すように、本実施形態では、横梁４は、２本設置されている。これらの横梁４は、ｘ方向に間隔を置いて配置されている。この間隔（ピッチ）は、縦梁３の全長に応じて、好適に設定されている。これにより、縦梁３をその長手方向の途中の２箇所で支持することができ、よって、縦梁３を採光部材２ごと十分に支持することができる。 As shown to FIG. 3, FIG. 8, the cross beam 4 is a beam which supports the vertical beam 3 from the downward direction with the lighting member 2. As shown in FIG. The cross beam 4 extends along the y direction. As shown in FIGS. 3 and 10, in the present embodiment, two cross beams 4 are provided. These cross beams 4 are arranged at intervals in the x direction. This interval (pitch) is suitably set according to the total length of the longitudinal beam 3. Thus, the vertical beams 3 can be supported at two places in the longitudinal direction, and thus the vertical beams 3 can be fully supported together with the light collecting member 2.

また、横梁４の設置本数は、本実施形態では２本であるが、これに限定されず、例えば、開口部３０７の大きさ、縦梁３の全長等の各種諸条件によっては、１本または３本以上としてもよい。 The number of horizontal beams 4 installed is two in this embodiment, but is not limited thereto. For example, depending on various conditions such as the size of the opening 307 and the total length of the vertical beams 3, one or more. It is good also as three or more.

図１１に示すように、各横梁４は、一例として、第１板状部４１１と、第２板状部４１２と、第２板状部４１３とを有する構造のものとなっている。第１板状部４１１、第２板状部４１２および第２板状部４１３は、いずれも、ｙ方向に沿った長尺な板状をなす部分である。第１板状部４１１は、その厚さ方向がｘ方向と平行となっている。第２板状部４１２は、第１板状部４１１に対して、ｚ方向正側に位置している。一方、第２板状部４１３は、第１板状部４１１に対して、ｚ方向負側に位置している。また、第２板状部４１２および第２板状部４１３は、それぞれ、その幅方向がｘ方向と平行となっている。このような構造の縦梁３は、第１板状部４１１、第２板状部４１２および第２板状部４１３の各板状部になり得る部材を所定箇所で溶接してなるものである。これにより、横梁４自身の剛性が向上し、よって、縦梁３を採光部材２ごと十分に支持することができる。 As shown in FIG. 11, each cross beam 4 has, for example, a structure having a first plate-like portion 411, a second plate-like portion 412, and a second plate-like portion 413. Each of the first plate-like portion 411, the second plate-like portion 412 and the second plate-like portion 413 is a long plate-like portion along the y direction. The thickness direction of the first plate-like portion 411 is parallel to the x-direction. The second plate-like portion 412 is located on the positive side in the z direction with respect to the first plate-like portion 411. On the other hand, the second plate-like portion 413 is located on the z-direction negative side with respect to the first plate-like portion 411. In addition, the width direction of each of the second plate-like portion 412 and the second plate-like portion 413 is parallel to the x-direction. The longitudinal beam 3 having such a structure is formed by welding members which can be the plate-like portions of the first plate-like portion 411, the second plate-like portion 412 and the second plate-like portion 413 at predetermined positions. . Thereby, the rigidity of the cross beam 4 itself is improved, and therefore, the vertical beam 3 can be sufficiently supported together with the light collecting member 2.

なお、横梁４は、例えば、鉄製のものである。この場合、横梁４の表面には、例えば、防錆めっき等の表面処理が施されているのが好ましい。 The cross beam 4 is made of iron, for example. In this case, the surface of the cross beam 4 is preferably subjected to surface treatment such as anticorrosion plating, for example.

図８に示すように、採光用構造体１は、縦梁３に対して採光部材２を固定する固定部５を備えている。なお、固定部５は、屋根３０に対する採光部材２の固定にも用いられる。また、図２、図３に示すように、固定部５は、縦梁３の長手方向に沿って、等間隔に複数配置されている。これにより、例えば、風等により採光部材２がめくれてしまうのを確実に防止することができる。 As shown in FIG. 8, the lighting structure 1 includes a fixing portion 5 that fixes the light collecting member 2 to the vertical beam 3. The fixing portion 5 is also used to fix the light collecting member 2 to the roof 30. Further, as shown in FIGS. 2 and 3, a plurality of fixing portions 5 are arranged at equal intervals along the longitudinal direction of the longitudinal beam 3. Thus, for example, it is possible to reliably prevent the light collecting member 2 from being turned up by wind or the like.

各固定部５は、配置箇所が異なること以外は、同じ構成であるため、以下、１つの固定部５について代表的に説明する。 The respective fixing portions 5 have the same configuration except that they are arranged in different places, and therefore, one fixing portion 5 will be representatively described below.

固定部５は、縦梁３の上側から突出したボルト５１と、ボルト５１が連結され、縦梁３に係合する係合部５２とを有している。 The fixing portion 5 has a bolt 51 protruding from the upper side of the vertical beam 3 and an engaging portion 52 connected with the bolt 51 and engaged with the vertical beam 3.

ボルト５１は、採光部材２の頂部２１２の貫通孔２１３を挿通する。そして、貫通孔２１３から突出したボルト５１には、ナット５３を螺合させることができる（図８参照）。これにより、縦梁３に対して採光部材２を固定することができる。このように、固定部５は、ボルト５１にナット５３を締め込む（締結する）という簡単な構成で、採光部材２を容易に固定することができる。 The bolt 51 is inserted through the through hole 213 of the top 212 of the light collecting member 2. The nut 53 can be screwed into the bolt 51 protruding from the through hole 213 (see FIG. 8). Thus, the light collecting member 2 can be fixed to the longitudinal beam 3. Thus, the fixing portion 5 can easily fix the daylighting member 2 with a simple configuration in which the nut 53 is tightened (fastened) to the bolt 51.

係合部５２は、縦梁３の第２板状部３１２に、例えば挟持により係合する部分である。この係合により、固定部５が縦梁３から離脱するのを防止することができる。 The engaging portion 52 is a portion engaged with the second plate-like portion 312 of the longitudinal beam 3 by, for example, holding. This engagement can prevent the fixing portion 5 from being separated from the vertical beam 3.

また、採光部材２は、固定部５を介して、頂部２１２で固定する構成となっている。この構成は、採光部材２の溝２２で固定した場合に比べて、貫通孔２１３から雨水等が浸入してくるのを確実に防止することができる。また、採光部材２を固定部５上に載置する際の作業性にも優れている。 In addition, the light collecting member 2 is configured to be fixed at the top portion 212 via the fixing portion 5. This configuration can reliably prevent rainwater and the like from infiltrating through the through hole 213 as compared with the case where the light fixing member 2 is fixed by the groove 22. Moreover, the workability at the time of mounting the lighting member 2 on the fixing | fixed part 5 is also excellent.

前述したように、固定部５は、屋根３０に対する採光部材２の固定にも用いられる。屋根３０の第１の凸条３０３Ａおよび第２の凸条３０３Ｂの頂部には、それぞれ、固定部５の係合部５２が係合する突片３０９が突出して形成されている。これにより、固定部５が第１の凸条３０３Ａや第２の凸条３０３Ｂから離脱するのを防止することができる。 As described above, the fixing portion 5 is also used to fix the light collecting member 2 to the roof 30. At the tops of the first ridges 303A and the second ridges 303B of the roof 30, projecting pieces 309 are formed to be engaged with the engaging portions 52 of the fixed portion 5. Thereby, it can prevent that fixed part 5 separates from the 1st convex rim 303A and the 2nd convex rim 303B.

次に、採光用構造体１を屋根３０に施工する施工方法（本発明の採光用構造体１の施工方法）について、図４〜図８を参照しつつ説明する。この施工方法は、第１の工程と、第２の工程と、第３の工程とを有する。 Next, the construction method (construction method of the structure 1 for daylighting of this invention) which constructs the structure 1 for daylighting on the roof 30 is demonstrated, referring FIGS. 4-8. This construction method has a first step, a second step, and a third step.

Moreover, it is preferable that the fixing | fixed part 5 is mounted | worn with the 1st convex 303A of the roof 30, and the 2nd convex 303B, respectively.

図５、図６に示すように、開口部３０７内に２本の縦梁３をそれぞれ設置、固定する。各縦梁３の設置箇所は、ｘ方向から見たとき、第１の凸条３０３Ａと第２の凸条３０３Ｂとの間の各凸条３０３と重なる位置である。また、各縦梁３にも固定部５が装着されているのが好ましい。 As shown in FIGS. 5 and 6, the two longitudinal beams 3 are respectively installed and fixed in the opening 307. The installation location of each vertical beam 3 is a position overlapping with each of the ridges 303 between the first ridge 303A and the second ridge 303B when viewed from the x direction. In addition, it is preferable that the fixing portion 5 be attached to each longitudinal beam 3 as well.

［２］第２の工程
図７、図８に示すように、縦梁３の上側に採光部材２を設置する。このとき、採光部材２の第１の凸条２１Ａを、屋根３０の第１の凸条３０３Ａに上側から重ねて係合させる。また、採光部材２の第２の凸条２１Ｂを、屋根３０の第２の凸条３０３Ｂに上側から重ねて係合させる。さらに、各固定部５のボルト５１を、採光部材２の貫通孔２１３に挿通させる。 [2] Second Step As shown in FIGS. 7 and 8, the light collecting member 2 is installed on the upper side of the vertical beam 3. At this time, the first ridges 21A of the light collecting member 2 are engaged with the first ridges 303A of the roof 30 from the upper side. Further, the second ridges 21B of the light collecting member 2 are engaged with the second ridges 303B of the roof 30 from the upper side in a superimposed manner. Further, the bolt 51 of each fixing portion 5 is inserted into the through hole 213 of the light collecting member 2.

［３］第３の工程
図８に示すように、各固定部５のボルト５１にナット５３を螺合させる。これにより、採光部材２が固定される。 [3] Third Step As shown in FIG. 8, the nut 53 is screwed onto the bolt 51 of each fixing portion 5. Thereby, the daylighting member 2 is fixed.

以上のような工程を経ることにより、屋根３０への採光用構造体１の施工を迅速かつ確実に行なうことができる。 By passing through the above processes, construction of the structure 1 for lighting to the roof 30 can be performed rapidly and reliably.

本実施形態は、縦梁を支持する構造が異なること以外は前記第１実施形態と同様である。 This embodiment is the same as the first embodiment except that the structure for supporting the longitudinal beam is different.

図１２に示すように、本実施形態では、採光用構造体１は、縦梁３をその端側から支持する支持部６を備えている。支持部６は、２つの支持部材（タイトフレーム）６１を有している。２つの支持部材６１のうちの一方の支持部材６１は、ｘ方向負側に位置する横梁４の第２板状部４１２上に固定されている。また、他方の支持部材６１は、ｘ方向正側に位置する横梁４の第２板状部４１２上に固定されている。これら２つの支持部材６１は、配置箇所が異なること以外は、同じ構成であるため、以下、１つの支持部材６１について代表的に説明する。 As shown in FIG. 12, in the present embodiment, the structure for light collection 1 is provided with a support portion 6 for supporting the longitudinal beam 3 from the end side thereof. The support 6 has two support members (tight frames) 61. One of the two support members 61 is fixed on the second plate-like portion 412 of the cross beam 4 located on the negative side in the x direction. The other support member 61 is fixed on the second plate-like portion 412 of the cross beam 4 positioned on the positive side in the x direction. Since these two support members 61 have the same configuration except that they are disposed at different places, one support member 61 will be representatively described below.

支持部材６１は、長尺状をなす金属板を、その長手方向の途中の所定箇所を折り曲げて、複数の凸部６２を形成した部材である。凸部６２のｙ方向の両側面は、それぞれ、傾斜面６２１となっている。傾斜面６２１同士がなす角度は、各凸条３０３における傾斜面３０５同士のなす角度と同じである。また、凸部６２の頂部６２２は、平坦となっている。 The support member 61 is a member in which a plurality of convex portions 62 are formed by bending an elongated metal plate at a predetermined position in the middle in the longitudinal direction. Both side surfaces in the y direction of the convex portion 62 are inclined surfaces 621. The angle formed by the inclined surfaces 621 is the same as the angle formed by the inclined surfaces 305 in the ridges 303. Further, the top portion 622 of the convex portion 62 is flat.

そして、縦梁３は、一方の支持部材６１の凸部６２と、他方の支持部材６１の凸部６２との間に、連結部材（図示せず）を介して、両持ち支持される。これにより、縦梁３は、採光部材２を支持可能な状態となる。 The vertical beam 3 is supported at both ends between the convex portion 62 of one support member 61 and the convex portion 62 of the other support member 61 via a connecting member (not shown). Thus, the vertical beam 3 can support the light collecting member 2.
