Description

この発明は、ルーバー材を有するルーバーシステム及びその製造方法に関する。   The present invention relates to a louver system having a louver material and a manufacturing method thereof.

特許文献１の段落［００２７］に記載されるように、建物の外装に用いられるルーバー材は、耐候性及び耐食性の向上のために溶融亜鉛めっき鋼材により形成されることがある。   As described in paragraph [0027] of Patent Document 1, a louver material used for an exterior of a building may be formed of a hot dip galvanized steel material in order to improve weather resistance and corrosion resistance.

しかしながら、溶融亜鉛めっき鋼材は溶接熱による歪みが生じやすい。また、鋼材にめっきを施す際に生じる急激な温度差によって熱歪みが生じることもある。そのため、溶融亜鉛めっき鋼材は寸法精度が良くなく、ルーバー材を下地材に取付ける際に穴位置が合わず取付け作業に長時間要したり、また不陸調整に長時間を要したりしていた。また、溶融亜鉛めっき鋼材の歪みを抑制するため、板厚を上げる必要があるため、製造コストが高くなるという問題もあった。   However, hot dip galvanized steel is susceptible to distortion due to welding heat. In addition, thermal distortion may occur due to a rapid temperature difference that occurs when the steel material is plated. For this reason, hot dip galvanized steel materials have poor dimensional accuracy, and when mounting the louver material to the base material, the hole positions do not match, and it takes a long time for the mounting work, and it takes a long time for the unevenness adjustment. . Moreover, since it is necessary to raise plate | board thickness in order to suppress the distortion of hot dip galvanized steel materials, there also existed a problem that manufacturing cost became high.

これに対し、特許文献２に示すルーバー材は、段落［００５２］に記載されるように、ＺＡＭ（登録商標）鋼板、すなわち、溶融亜鉛−アルミニウム−マグネシウム合金めっき鋼板によって形成される場合がある。溶融亜鉛−アルミニウム−マグネシウム合金めっき鋼板によって形成されるルーバー材は、耐候性及び耐食性が良い上に、歪みが生じにくく、薄い板厚であっても良好な寸法精度で成形することができる。   On the other hand, the louver material shown in Patent Document 2 may be formed of a ZAM (registered trademark) steel sheet, that is, a hot dip zinc-aluminum-magnesium alloy plated steel sheet, as described in paragraph [0052]. The louver material formed of a hot dip zinc-aluminum-magnesium alloy plated steel sheet has good weather resistance and corrosion resistance, and is less likely to be distorted, and can be formed with good dimensional accuracy even with a thin plate thickness.

以下、この発明の実施の形態について添付図面に基づいて説明する。
実施の形態１．
図１及び２に示すように、ルーバーシステム１００は、下地材１５と、下地材１５の長手方向に沿って下地材１５に取り付けられるルーバー材ユニット１０とを有する。なお、以下の説明において、下地材１５が延びる長手方向を上下方向Ｖとし、下地材１５の短手方向を横方向Ｗとする。 Embodiments of the present invention will be described below with reference to the accompanying drawings.
Embodiment 1 FIG.
As shown in FIGS. 1 and 2, the louver system 100 includes a base material 15 and a louver material unit 10 attached to the base material 15 along the longitudinal direction of the base material 15. In the following description, the longitudinal direction in which the base material 15 extends is the vertical direction V, and the short direction of the base material 15 is the lateral direction W.

１個の下地材１５につき、隣り合うルーバー材ユニット１０の各々の端部が横方向Ｗに間隔を空けて取り付けられている。また、各々のルーバー材ユニット１０の他端は別の下地材１５に取り付けられる。また、ルーバー材ユニット１０は、図３に示すルーバー材２が上下方向Ｖに複数枚連結されて構成されている。ルーバー材２の各々は、片側施工ボルト１１により下地材１５に固定されている。
なお、片側施工ボルトとは、一方向側からの締付作業のみで部材を連結することができるボルトをいう。 With respect to one base material 15, the end portions of the adjacent louver material units 10 are attached at intervals in the lateral direction W. The other end of each louver material unit 10 is attached to another base material 15. Further, the louver material unit 10 is configured by connecting a plurality of louver materials 2 shown in FIG. Each of the louver members 2 is fixed to the base material 15 with one-side construction bolts 11.
In addition, a one-side construction bolt means the volt | bolt which can connect a member only by the fastening operation | work from one direction side.

図３に示すように、ルーバー材２の各々は、略Ｖ字形状の断面を有する板形状の鋼板である。ルーバー材２の中央には、ルーバー材２の長手方向に伸びる頂面部２ａが形成され、頂面部２ａの両側には一対の斜面部２ｂが形成される。さらにまた、各々の斜面部２ｂの外側には取付面部２ｃが形成される。そして、ルーバー材２の四隅、すなわち、取付面部２ｃの各々の長手方向の両端には第一ボルト孔１８ａが形成されている。また、ルーバー材２には全体的に複数のパンチング孔３が形成されている。
なお、ルーバー材２及び下地材１５は、ともに溶融亜鉛−アルミニウム−マグネシウム合金めっき鋼板によって形成されている。 As shown in FIG. 3, each of the louver members 2 is a plate-shaped steel plate having a substantially V-shaped cross section. A top surface portion 2a extending in the longitudinal direction of the louver material 2 is formed at the center of the louver material 2, and a pair of slope portions 2b are formed on both sides of the top surface portion 2a. Furthermore, an attachment surface portion 2c is formed on the outer side of each slope portion 2b. And the 1st bolt hole 18a is formed in the four corners of the louver material 2, ie, the both ends of each longitudinal direction of the attachment surface part 2c. A plurality of punching holes 3 are formed in the louver material 2 as a whole.
The louver material 2 and the base material 15 are both formed of a hot dip zinc-aluminum-magnesium alloy plated steel plate.

そして、図４及び５に示すように、上下方向Ｖにおいて隣り合うルーバー材２同士は、各々、隣接する取付面部２ｃが互いに重なり合うように配置される。なお、図５において、上に重なる方の取付面部２ｃを第一取付面部２ｃ１とし、第一取付面部２ｃ１の下に重なり合う取付面部２ｃを第二取付面部２ｃ２とする。ルーバー材２は、第一取付面部２ｃ１及び第二取付面部２ｃ２の第一ボルト孔１８ａに挿入される片側施工ボルト１１によって下地材１５に取り付けられるとともに、ルーバー材２同士が連結され、ルーバー材ユニット１０が構成される。   4 and 5, the louver members 2 adjacent in the vertical direction V are arranged such that the adjacent mounting surface portions 2c overlap each other. In FIG. 5, the upper mounting surface portion 2c is referred to as a first mounting surface portion 2c1, and the mounting surface portion 2c overlapping below the first mounting surface portion 2c1 is referred to as a second mounting surface portion 2c2. The louver material 2 is attached to the base material 15 by the one-side construction bolts 11 inserted into the first bolt holes 18a of the first attachment surface portion 2c1 and the second attachment surface portion 2c2, and the louver materials 2 are connected to each other, so that the louver material unit. 10 is configured.

ここで、図４及び５に示すように、下地材１５は矩形の閉鎖断面を有する鋼管である。下地材１５の、ルーバー材２の取り付け側には、片側施工ボルト１１が挿入される第二ボルト孔１８ｂが形成される。各々の第二ボルト孔１８ｂはルーバー材２の第一ボルト孔１８ａに対応しており、ルーバー材２が下地材１５に固定される際には、片側施工ボルト１１は、ルーバー材２の側からルーバー材２の第一ボルト孔１８ａ及び下地材１５の第二ボルト孔１８ｂに挿入される。なお、下地材１５の第二ボルト孔１８ｂの径は、ルーバー材２の第一ボルト孔１８ａの径よりも小さい。   Here, as shown in FIGS. 4 and 5, the base material 15 is a steel pipe having a rectangular closed cross section. A second bolt hole 18b into which the one-side construction bolt 11 is inserted is formed on the base material 15 on the side where the louver material 2 is attached. Each of the second bolt holes 18 b corresponds to the first bolt hole 18 a of the louver material 2, and when the louver material 2 is fixed to the base material 15, the one-side construction bolt 11 is moved from the louver material 2 side. It is inserted into the first bolt hole 18 a of the louver material 2 and the second bolt hole 18 b of the base material 15. The diameter of the second bolt hole 18b of the base material 15 is smaller than the diameter of the first bolt hole 18a of the louver material 2.

また、ルーバーシステム１００が設けられる外壁１にはアンカーボルト１７によってＬ字金具１６が取り付けられる。Ｌ字金具１６は、下地材１５の各々に対応して一対ずつ配置される。そして、一対のＬ字金具１６の間には下地材１５が片側施工ボルト１１で取り付けられている。なお、Ｌ字金具１６を介して外壁１に取り付けられる下地材１５は外壁１には直接的には接せず、下地材１５と外壁１の間にはやや隙間が空いている。
また、下地材１５は、片側施工ボルト１１の代わりに、一対のＬ字金具１６の間を貫通する通しボルトによってＬ字金具１６に取付けられていてもよい。また、下地材１５は溶接によって一対のＬ字金具１６に取付けられていてもよい。 Further, an L-shaped metal fitting 16 is attached to the outer wall 1 where the louver system 100 is provided by an anchor bolt 17. A pair of L-shaped metal fittings 16 is arranged corresponding to each of the base materials 15. A base material 15 is attached with a one-side construction bolt 11 between the pair of L-shaped metal fittings 16. Note that the base material 15 attached to the outer wall 1 via the L-shaped metal fitting 16 does not directly contact the outer wall 1, and there is a slight gap between the base material 15 and the outer wall 1.
Moreover, the base material 15 may be attached to the L-shaped metal fitting 16 by a through bolt that penetrates between the pair of L-shaped metal fittings 16 instead of the one-side construction bolt 11. Moreover, the base material 15 may be attached to a pair of L-shaped metal fittings 16 by welding.

ここで、ルーバーシステム１００に用いられる片側施工ボルト１１は、図６に示すようなタッピング型のボルトである。すなわち、片側施工ボルト１１は、頭部１１ａと軸部１１ｂとを有している。軸部１１ｂには雄ねじ部１１ｃが形成されている。なお、片側施工ボルト１１の軸部１１ｂの径はルーバー材２の第一ボルト孔１８ａよりも小さく、下地材１５の第二ボルト孔１８ｂよりも大きい。また、軸部１１ｂの先端側には軸部１１ｂよりも径が小さい小径部１１ｄが設けられる。小径部１１ｄの径は下地材１５の第二ボルト孔１８ｂの径よりもやや小さい。また、軸部１１ｂと小径部１１ｄとの間には、小径部１１ｄから軸部１１ｂに向かうにつれて径が大きくなるテーパ形状の拡径部１１ｅが設けられる。ここで、小径部１１ｄ及び拡径部１１ｅは、軸部１１ｂを第二ボルト孔１８ｂに案内するためのガイド部１１ｆを構成する。また、片側施工ボルト１１の頭部１１ａの下には、フランジ１１ｇが設けられている。   Here, the one-side construction bolt 11 used in the louver system 100 is a tapping bolt as shown in FIG. That is, the one-side construction bolt 11 has a head portion 11a and a shaft portion 11b. A male screw portion 11c is formed on the shaft portion 11b. The diameter of the shaft portion 11 b of the one-side construction bolt 11 is smaller than the first bolt hole 18 a of the louver material 2 and larger than the second bolt hole 18 b of the base material 15. A small-diameter portion 11d having a smaller diameter than the shaft portion 11b is provided on the distal end side of the shaft portion 11b. The diameter of the small diameter portion 11d is slightly smaller than the diameter of the second bolt hole 18b of the base material 15. Further, between the shaft portion 11b and the small diameter portion 11d, there is provided a tapered enlarged diameter portion 11e having a diameter that increases from the small diameter portion 11d toward the shaft portion 11b. Here, the small diameter portion 11d and the large diameter portion 11e constitute a guide portion 11f for guiding the shaft portion 11b to the second bolt hole 18b. A flange 11 g is provided below the head 11 a of the one-side construction bolt 11.

また、片側施工ボルト１１には、表面処理として、亜鉛めっきが施された後に焼き付け塗装が行われる。ここで、片側施工ボルト１１に施される表面処理は、溶融亜鉛−アルミニウム−マグネシウム合金めっき鋼板と同様のレベルの耐食性を有するものであるものとし、なおかつ、異種金属接触腐食が抑制できる膜厚であるものとする。具体的には、片側施工ボルト１１が下地材１５の第二ボルト孔１８ｂに挿入される際にも摩擦のために剥がれず、かつ、異種金属接触腐食を抑制できる程度の膜厚として、片側施工ボルト１１には電気亜鉛めっきが２〜１０μｍ施された後、３〜２０μｍの膜厚の焼き付け塗装が施される。これにより、ルーバー材２よりも先に片側施工ボルト１１が腐食してしまい、もらい錆によってルーバーシステム１００の耐用年数が短くなってしまうという事態を防止することができる。   Further, the one-side construction bolt 11 is baked and coated as a surface treatment after being galvanized. Here, the surface treatment applied to the one-side applied bolt 11 is assumed to have the same level of corrosion resistance as that of the hot-dip zinc-aluminum-magnesium alloy-plated steel sheet, and with a film thickness that can suppress contact corrosion of different metals. It shall be. Specifically, when the one-side construction bolt 11 is inserted into the second bolt hole 18 b of the base material 15, the one-side construction is performed with a film thickness that does not peel off due to friction and can suppress contact corrosion of dissimilar metals. The bolt 11 is subjected to electrogalvanizing 2-10 μm and then baked with a film thickness of 3-20 μm. Thereby, the situation where the one-side construction bolt 11 corrodes ahead of the louver material 2 and the service life of the louver system 100 is shortened due to rusting can be prevented.

また、片側施工ボルト１１がルーバー材２と下地材１５とを締結させる時は、片側施工ボルト１１は、まずルーバー材２側からルーバー材２の第一ボルト孔１８ａに挿入される。そして、片側施工ボルト１１は、ガイド部１１ｆに案内されて下地材１５の第二ボルト孔１８ｂに位置合わせされ、図示しない工具によって回転させられながら下地材１５の第二ボルト孔１８ｂに挿入される。ここで、片側施工ボルト１１の回転に伴って、第二ボルト孔１８ｂの内周面には、片側施工ボルト１１の雄ねじ部１１ｃに係合する雌ねじ部１８ｃが塑性変形により形成される。これにより、片側施工ボルト１１と下地材１５の第二ボルト孔１８ｂとの間に働く摩擦力によって、ルーバー材２と下地材１５とは堅固に締結される。また、塑性変形により雌ねじ部が形成される片側施工ボルト１１を用いると、施工時に切粉が発生しないため、もらい錆が生じるおそれがない。このような片側施工ボルト１１としては、例えば、株式会社ロブテックスファスニングシステム製のシュアツイスト（登録商標）が用いられる。   When the one-side construction bolt 11 fastens the louver material 2 and the base material 15, the one-side construction bolt 11 is first inserted into the first bolt hole 18 a of the louver material 2 from the louver material 2 side. The one-side construction bolt 11 is guided by the guide portion 11f, aligned with the second bolt hole 18b of the base material 15, and inserted into the second bolt hole 18b of the base material 15 while being rotated by a tool (not shown). . Here, with the rotation of the one-side construction bolt 11, a female thread portion 18c that engages with the male thread portion 11c of the one-side construction bolt 11 is formed on the inner peripheral surface of the second bolt hole 18b by plastic deformation. Thereby, the louver material 2 and the base material 15 are firmly fastened by the friction force acting between the one-side construction bolt 11 and the second bolt hole 18b of the base material 15. Moreover, when the one-side construction bolt 11 in which the female thread part is formed by plastic deformation is used, there is no possibility of rusting because no chips are generated during construction. As such a one-side construction bolt 11, for example, Sure Twist (registered trademark) manufactured by Lobtex Fastening System Co., Ltd. is used.

以上より、この実施の形態１に係るルーバーシステム１００では、下地材１５が溶融亜鉛−アルミニウム−マグネシウム合金めっき鋼板により形成されることにより、耐候性及び耐食性が向上する。また、ルーバー材２に設けられる第一ボルト孔１８ａ及び下地材１５に設けられる第二ボルト孔１８ｂに、タッピング型のボルトである片側施工ボルト１１が挿入されることによって、ルーバー材２と下地材１５とが堅固に締結される。従って、一方向側からの作業のみで、片側施工ボルト１１を介してルーバー材２と下地材１５とを締結させることができ、施工性が向上する。   As described above, in the louver system 100 according to the first embodiment, the weather resistance and the corrosion resistance are improved by forming the base material 15 from the hot dip zinc-aluminum-magnesium alloy plated steel sheet. Further, the louver material 2 and the base material are inserted by inserting the one-side construction bolt 11 which is a tapping bolt into the first bolt hole 18a provided in the louver material 2 and the second bolt hole 18b provided in the base material 15. 15 is firmly fastened. Therefore, the louver material 2 and the base material 15 can be fastened through the one-side construction bolts 11 only by work from one direction side, and workability is improved.

特に、ルーバーシステム１００の下地材１５が閉鎖断面を有する場合であっても、各々の下地材１５には一方向側から第二ボルト孔１８ｂのみを形成すればよい。従って、作業者はルーバー材２側からの作業でルーバー材２を下地材１５に容易に取り付けることができ、施工性がより向上するとともに製造コストを抑えることができる。
なお、下地材１５は溝形鋼であってもよく、溝形鋼の一方の側面部が塞がれて実質的に下地材１５に閉鎖断面が形成されているような場合であっても、片側施工ボルト１１を用いて、一方向側からルーバー材２を下地材１５に容易に取り付けることができる。 In particular, even if the base material 15 of the louver system 100 has a closed cross section, each base material 15 may be formed with only the second bolt holes 18b from one side. Therefore, the operator can easily attach the louver material 2 to the base material 15 by work from the louver material 2 side, and the workability can be further improved and the manufacturing cost can be suppressed.
Note that the base material 15 may be channel steel, and even when one side surface portion of the channel steel is closed and a substantially closed cross section is formed in the base material 15, The louver material 2 can be easily attached to the base material 15 from one side using the one-side construction bolt 11.

さらに、ルーバーシステム１００では、下地材１５だけでなくルーバー材２も溶融亜鉛−アルミニウム−マグネシウム合金めっき鋼板によって形成されるため、ルーバーシステム１００の耐候性及び耐食性がより向上する。   Furthermore, in the louver system 100, not only the base material 15 but also the louver material 2 is formed of a hot dip galvanized aluminum-magnesium alloy plated steel plate, so that the weather resistance and corrosion resistance of the louver system 100 are further improved.

また、ルーバーシステム１００には、図６に示すようなタッピング型の片側施工ボルト１１の他に、図７に示すような片側施工ボルト２１を用いてもよい。片側施工ボルト２１は、雄ねじ部２２ａを有する軸部２１ａと、軸部２１ａの周りに設けられる略円筒形状のスリーブ部２１ｂとを有している。スリーブ部２１ｂの内周面には、雄ねじ部２２ａに係合する雌ねじ部２２ｂが形成される。また、スリーブ部２１ｂの一端部には、径方向外側に円形状に広がる頭部２１ｃが形成される。
なお、片側施工ボルト２１が挿入されるために、ルーバー材２には第一ボルト孔１９ａが形成され、下地材１５には第二ボルト孔１９ｂが形成される。第一ボルト孔１９ａと第二ボルト孔１９ｂとは同じ径を有していてもよいし、１９ａの穴径は１９ｂより大きくともよい。 Further, in the louver system 100, in addition to the tapping type one-side construction bolt 11 as shown in FIG. 6, a one-side construction bolt 21 as shown in FIG. 7 may be used. The one-side construction bolt 21 has a shaft portion 21a having a male screw portion 22a, and a substantially cylindrical sleeve portion 21b provided around the shaft portion 21a. A female screw portion 22b that engages with the male screw portion 22a is formed on the inner peripheral surface of the sleeve portion 21b. Further, a head portion 21c that extends in a circular shape on the radially outer side is formed at one end portion of the sleeve portion 21b.
Since the one-side construction bolt 21 is inserted, the first bolt hole 19a is formed in the louver material 2, and the second bolt hole 19b is formed in the base material 15. The first bolt hole 19a and the second bolt hole 19b may have the same diameter, and the hole diameter of 19a may be larger than 19b.

片側施工ボルト２１は、まず、図８（ｉ）に示すように、軸部２１ａがスリーブ部２１ｂに挿入された状態で、図８（ｉｉ）に示すように、ルーバー材２の側からルーバー材２の第一ボルト孔１９ａ及び下地材１５の第二ボルト孔１９ｂに挿入される。そして、図８（ｉｉｉ）に示すように、図示しない工具で軸部２１ａを回転させることにより、スリーブ部２１ｂの先端部は塑性変形しながら上昇する。これにより、スリーブ部２１ｂには、下地材１５の第二ボルト孔１９ｂを塞ぐように径方向外側に膨らんだバルジ部２１ｄが形成される。これにより、ルーバー材２及び下地材１５は、頭部２１ｃとバルジ部２１ｄとの間に挟み込まれ、互いに締結される。従って、ルーバー材２と下地材１５とがこのように締結されることで、鋼材の切り粉の発生がなく、切り粉を片付ける作業を省略することができるとともに、切り粉が腐食することによってもらい錆が生じるおそれがない。   As shown in FIG. 8 (i), the one-side construction bolt 21 is a louver material from the louver material 2 side as shown in FIG. 8 (ii) in a state where the shaft portion 21a is inserted into the sleeve portion 21b. The first bolt hole 19 a and the second bolt hole 19 b of the base material 15 are inserted. Then, as shown in FIG. 8 (iii), by rotating the shaft portion 21a with a tool (not shown), the tip portion of the sleeve portion 21b rises while being plastically deformed. As a result, a bulge portion 21 d swelled radially outward so as to close the second bolt hole 19 b of the base material 15 is formed in the sleeve portion 21 b. Thus, the louver material 2 and the base material 15 are sandwiched between the head portion 21c and the bulge portion 21d and fastened to each other. Therefore, the louver material 2 and the base material 15 are fastened in this way, so that there is no generation of steel chips, and the work of cleaning up the chips can be omitted, and the chips are corroded. There is no risk of rusting.

また、片側施工ボルト２１にも、片側施工ボルト１１と同様に、亜鉛めっきが施された後に焼き付け塗装が行われる。具体的には、片側施工ボルト２１のスリーブ部２１ｂが塑性変形しても剥がれず、かつ、異種金属接触腐食を抑制できる程度の膜厚として、片側施工ボルト２１には電気亜鉛めっきが２〜１０μｍ施された後、５〜２５μｍの膜厚の焼き付け塗装が施される。   In addition, similarly to the one-side construction bolt 11, the one-side construction bolt 21 is baked and coated after galvanization. Specifically, electrogalvanizing is applied to the one-side applied bolt 21 with a thickness of 2 to 10 μm so that the sleeve portion 21b of the one-side applied bolt 21 does not peel even when plastically deformed and can suppress dissimilar metal contact corrosion. After being applied, baking coating with a film thickness of 5 to 25 μm is applied.

実施の形態２．
次に、この発明の実施の形態２に係るルーバーシステム２００の構成を図９に示す。ルーバーシステム２００は、ルーバーシステム１００の下地材１５に替わって下地材２１５が用いられるものである。なお、図１〜８の参照符号と同一の符号は同一又は同様の構成要素であるので、その詳細な説明は省略する。
図９に示すように、ルーバーシステム２００が設けられる外壁１にはアンカーボルト１７によってＬ字金具１６が取り付けられる。そして、Ｌ字金具１６のうち、外壁１に対して垂直に延びる部材取付部１６ａの両面には、一対の軽量山形鋼である下地材２１５が取付けられる。ここで、Ｌ字金具１６と、Ｌ字金具１６を間に挟む一対の下地材２１５とは、締結部材２１３によって固定される。締結部材２１３はボルト２１３ａとナット２１３ｂとを有している。すなわち、ボルト２１３ａとナット２１３ｂとの締め付けにより下地材２１５はＬ字金具１６に堅固に固定される。
ここで、下地材２１５は溶融亜鉛−アルミニウム−マグネシウム合金めっき鋼板により形成される。 Embodiment 2. FIG.
Next, FIG. 9 shows the configuration of a louver system 200 according to Embodiment 2 of the present invention. The louver system 200 uses a base material 215 instead of the base material 15 of the louver system 100. Note that the same reference numerals as those in FIGS. 1 to 8 are the same or similar components, and thus detailed description thereof is omitted.
As shown in FIG. 9, the L-shaped bracket 16 is attached to the outer wall 1 where the louver system 200 is provided by anchor bolts 17. And the base material 215 which is a pair of lightweight angle steel is attached to both surfaces of the member attachment part 16a extended perpendicularly | vertically with respect to the outer wall 1 among the L-shaped metal fittings 16. FIG. Here, the L-shaped bracket 16 and the pair of base materials 215 sandwiching the L-shaped bracket 16 therebetween are fixed by a fastening member 213. The fastening member 213 has a bolt 213a and a nut 213b. That is, the base material 215 is firmly fixed to the L-shaped metal fitting 16 by tightening the bolt 213a and the nut 213b.
Here, the base material 215 is formed of a hot dip zinc-aluminum-magnesium alloy plated steel plate.

なお、軽量山形鋼である下地材２１５のうち、Ｌ字金具１６に取付ける側の平面部を金具取付面部２１５ａとする。また、下地材２１５のうち、金具取付面部２１５ａに直交する平面部はルーバー材取付面部２１５ｂとし、ルーバー材取付面部２１５ｂには、ルーバー材２が片側施工ボルト１１によって取付けられている。また、下地材２１５のルーバー材取付面部２１５ｂには、片側施工ボルト１１が挿入される第二ボルト孔２１８が形成される。各々の第二ボルト孔２１８はルーバー材２の第一ボルト孔１８ａに対応している。そのため、ルーバー材２が下地材２１５に固定される際には、片側施工ボルト１１は、ルーバー材２の側からルーバー材２の第一ボルト孔１８ａ及び下地材２１５の第二ボルト孔２１８に挿入される。   In addition, let the plane part of the side attached to the L-shaped metal fitting 16 among the base materials 215 which are lightweight angle steel be the metal fitting attachment surface part 215a. In addition, in the base material 215, a flat portion perpendicular to the metal fitting attachment surface portion 215a is a louver material attachment surface portion 215b, and the louver material 2 is attached to the louver material attachment surface portion 215b by a one-side construction bolt 11. Further, a second bolt hole 218 into which the one-side construction bolt 11 is inserted is formed in the louver material attachment surface portion 215b of the base material 215. Each second bolt hole 218 corresponds to the first bolt hole 18 a of the louver material 2. Therefore, when the louver material 2 is fixed to the base material 215, the one-side construction bolt 11 is inserted into the first bolt hole 18 a of the louver material 2 and the second bolt hole 218 of the base material 215 from the louver material 2 side. Is done.

以上より、この実施の形態２に係るルーバーシステム２００では、ルーバーシステム１００と同様に、下地材２１５が溶融亜鉛−アルミニウム−マグネシウム合金めっき鋼板により形成されることにより、耐候性及び耐食性が向上する。また、ルーバー材２に設けられる第一ボルト孔１８ａ及び下地材２１５に設けられる第二ボルト孔２１８には、片側施工ボルト１１が挿入される。従って、一方向側からの作業のみで、片側施工ボルト１１を介してルーバー材２と下地材２１５とを堅固に締結させることができ、施工性が向上する。
なお、タッピング型のボルトである片側施工ボルト１１に替えて、図７に示すような片側施工ボルト２１を使用してもよい。 As described above, in the louver system 200 according to the second embodiment, as in the louver system 100, the base material 215 is formed of a hot dip zinc-aluminum-magnesium alloy plated steel plate, thereby improving weather resistance and corrosion resistance. The one-side construction bolt 11 is inserted into the first bolt hole 18 a provided in the louver material 2 and the second bolt hole 218 provided in the base material 215. Therefore, the louver material 2 and the base material 215 can be firmly fastened through the one-side construction bolt 11 only by work from one direction side, and workability is improved.
In addition, it may replace with the one side construction bolt 11 which is a tapping type bolt, and may use the one side construction bolt 21 as shown in FIG.

また、この発明の実施の形態１及び２に係るルーバーシステムは、図２に示すルーバーシステム１００のように、ルーバー材２が上下方向Ｖに複数枚連結されてルーバー材ユニット１０を構成する例に限定されない。具体的には、図１０に示すルーバーシステム３００のように、ルーバー材２同士が上下方向Ｖに一定の間隔を空けて下地材１５に取り付けられていてもよい。
また、ルーバー材２は縦向き、すなわち、上下方向Ｖに平行に延びる向きに配置されてもよく、さらに、ルーバー材２は、上下方向Ｖに対して斜めになるような向きで配置されてもよい。 Further, the louver system according to the first and second embodiments of the present invention is an example in which a plurality of louver members 2 are connected in the vertical direction V to form the louver member unit 10 as in the louver system 100 shown in FIG. It is not limited. Specifically, like the louver system 300 shown in FIG. 10, the louver members 2 may be attached to the base material 15 with a certain interval in the vertical direction V.
Further, the louver material 2 may be arranged in a vertical direction, that is, in a direction extending in parallel with the vertical direction V. Further, the louver material 2 may be arranged in an oblique direction with respect to the vertical direction V. Good.
