上記した特許文献1記載の構造は、建物から張り出す方向にルーバー材を接合したものではなかった。しかしながら、建物から張り出す方向にルーバー材を接合してルーバーパネルを構成できれば、大きく張り出した形状の大型のルーバーを容易に構成でき、かつ、部品数や製造コストの増加を抑えることができる。   The structure described in Patent Document 1 described above is not a structure in which a louver material is joined in a direction protruding from a building. However, if a louver panel can be constructed by joining louver members in a direction projecting from a building, a large louver with a large projecting shape can be easily constructed, and an increase in the number of parts and manufacturing costs can be suppressed.

なお、建物から張り出す方向にルーバー材を接合した場合、ルーバー材の接合部の接合強度が求められる。更には、仮に接合が外れた場合でもルーバー材の落下を防止できるように、落下防止手段を備えることが望ましい。   In addition, when a louver material is joined in a direction protruding from a building, the joining strength of the joint portion of the louver material is required. Furthermore, it is desirable to provide a fall prevention means so that the louver material can be prevented from falling even if the joint is disconnected.

ルーバー材の落下防止手段としては、例えば特許文献2記載の構造を建築用ルーバーパネルの落下防止構造に応用することが考えられるが、この特許文献2記載の構造はルーバーパネルの重みに耐えられずにクリップが外れるおそれがあるという欠点がある。   As a means for preventing the fall of the louver material, for example, the structure described in Patent Document 2 may be applied to the structure for preventing the fall of a building louver panel. However, the structure described in Patent Document 2 cannot withstand the weight of the louver panel. There is a disadvantage that the clip may come off.

そこで、本発明は、建物から張り出す方向に複数のルーバー材を接合してルーバーパネルを製作することができ、かつ、このようなルーバーパネルに最適な落下防止構造を提供することを課題とする。   Therefore, an object of the present invention is to provide a louver panel that can be manufactured by joining a plurality of louver members in a direction protruding from a building, and that is optimal for such a louver panel. .

A first embodiment of the present invention will be described with reference to FIGS.

本実施形態に係る建築用ルーバーパネル30は、複数の長尺のルーバー材10を接合して構成される。この建築用ルーバーパネル30は、例えば図1に示すように、左右に所定の間隔を設けて垂直方向に配置することができる。この図1に示す例では、壁などの建物躯体31に下地材32を介してルーバー材10を固定し、このルーバー材10に対して更に他のルーバー材10を連結して建築用ルーバーパネル30を構成している。なお、建築用ルーバーパネル30は、図1のように垂直方向に配置するのみならず、例えば図2に示すように、上下に所定の間隔を設けて水平方向に配置することもできる。   The architectural louver panel 30 according to the present embodiment is configured by joining a plurality of long louver members 10. For example, as shown in FIG. 1, the building louver panel 30 can be arranged in the vertical direction with a predetermined interval on the left and right. In the example shown in FIG. 1, a louver material 10 is fixed to a building frame 31 such as a wall via a base material 32, and another louver material 10 is connected to the louver material 10 to construct a building louver panel 30. Is configured. Note that the building louver panel 30 can be arranged not only in the vertical direction as shown in FIG. 1 but also in the horizontal direction with a predetermined distance above and below as shown in FIG. 2, for example.

ルーバー材10は、その端部に他のルーバー材10を連結するための凹凸形状の接続部を備えている。本実施形態においては、凹形状の接続部を備えたルーバー材10を一方のルーバー材Aと呼び、凸形状の接続部を備えたルーバー材10を他方のルーバー材Bと呼ぶ。なお、ルーバー材10の一端に凹形状の接続部を設けるとともに、他端に凸形状の接続部を設けることで、ルーバー材10を3つ以上直列に接続できるようにしてもよい。この場合、1つのルーバー材10が一方のルーバー材Aでもあり他方のルーバー材Bでもあることになる。すなわち、あるルーバー材10が一方のルーバー材Aでもあるか他方のルーバー材Bであるかは、ルーバー材10をどのように接続するかによって逆転する場合もある。   The louver material 10 is provided with a concavo-convex connection portion for connecting another louver material 10 to the end portion thereof. In the present embodiment, the louver material 10 having a concave connection portion is called one louver material A, and the louver material 10 having a convex connection portion is called the other louver material B. Note that three or more louver members 10 may be connected in series by providing a concave connection portion at one end of the louver member 10 and providing a convex connection portion at the other end. In this case, one louver material 10 is one louver material A and the other louver material B. That is, whether a certain louver material 10 is one louver material A or the other louver material B may be reversed depending on how the louver material 10 is connected.

一方のルーバー材Aは、図3に示すように、端部に開口部11を有することで凹形状の接続部を形成している。この一方のルーバー材Aは、開口部11を形成する一対の連結脚12と、前記一対の連結脚12の内面に互いに対向するように形成された一対の引掛部13と、前記一対の連結脚12を連結するように設けられた補強壁15と、を備えている。   As shown in FIG. 3, one louver material A has an opening 11 at an end portion to form a concave connection portion. The one louver material A includes a pair of connecting legs 12 that form the opening 11, a pair of hook portions 13 that are formed to face the inner surfaces of the pair of connecting legs 12, and the pair of connecting legs.

支持材26は、図4に示すような筒状であり、一方のルーバー材Aの補強壁15と他方のルーバー材Bの平坦部25との間に挿入されて、両端がそれぞれ補強壁15と平坦部25とに当接するように配置される(図5参照)。この支持材26は、図4及び図5に示すように、補強壁15に穿設された挿通孔15cと平坦部25に穿設された挿通孔25aとを貫通するボルト27によって取り付けられる。すなわち、一方のルーバー材Aまたは他方のルーバー材Bのうちの一方の側からボルト27を差し込み、このボルト27を支持材26の挿通部26aに貫通させ、更に、一方のルーバー材Aまたは他方のルーバー材Bのうちの他方の側に貫通させる。貫通させたボルト27にナット28を螺着させることで、一方のルーバー材Aと他方のルーバー材Bとを強固に固定する。   The support member 26 has a cylindrical shape as shown in FIG. 4 and is inserted between the reinforcing wall 15 of one louver material A and the flat portion 25 of the other louver material B, and both ends thereof are respectively connected to the reinforcing wall 15 and the reinforcing wall 15. It arrange | positions so that it may contact | abut to the flat part 25 (refer FIG. 5). As shown in FIGS. 4 and 5, the support member 26 is attached by a bolt 27 that passes through an insertion hole 15 c formed in the reinforcing wall 15 and an insertion hole 25 a formed in the flat portion 25. That is, a bolt 27 is inserted from one side of one louver material A or the other louver material B, this bolt 27 is passed through the insertion portion 26a of the support material 26, and further, one louver material A or the other louver material A is inserted. The other side of the louver material B is penetrated. One louver material A and the other louver material B are firmly fixed to each other by screwing the nut 28 onto the penetrated bolt 27.

このとき、ボルト27をナット28に締め込むことで補強壁15や平坦部25に大きな力が加わることになるが、このような力によって補強壁15や平坦部25が変形すると凹凸形状の接合が外れるおそれがある。しかしながら、本実施形態においては、支持材26が補強壁15と平坦部25との間に設けられているため、支持材26によって補強壁15や平坦部25の変形が抑制される。このような構成によれば、ボルト27及びナット28によって一方のルーバー材Aと他方のルーバー材Bとを強固に固定することができるとともに、補強壁15や平坦部25の変形を抑制して接続部形材同士の接合を外れにくくすることができる。   At this time, by tightening the bolt 27 into the nut 28, a large force is applied to the reinforcing wall 15 and the flat portion 25. When the reinforcing wall 15 and the flat portion 25 are deformed by such a force, the concave and convex shape is joined. May come off. However, in this embodiment, since the support member 26 is provided between the reinforcing wall 15 and the flat portion 25, the deformation of the reinforcing wall 15 and the flat portion 25 is suppressed by the support member 26. According to such a configuration, one louver material A and the other louver material B can be firmly fixed by the bolts 27 and the nuts 28, and the deformation of the reinforcing wall 15 and the flat portion 25 is suppressed and connected. It is possible to make it difficult to disconnect the part-shaped members from each other.

なお、前述したように、一方のルーバー材Aの補強壁15と他方のルーバー材Bの平坦部25とには、それぞれ支持材26をスライドさせるための支持部材ガイド15d,25eが突出形成されており、側方から挿入した支持材26を容易に挿通孔15c、25aの位置までスライドさせることができる。   As described above, the reinforcing wall 15 of one louver material A and the flat portion 25 of the other louver material B are provided with support member guides 15d and 25e for projecting the support material 26, respectively. Thus, the support member 26 inserted from the side can be easily slid to the positions of the insertion holes 15c and 25a.

このように、本実施形態によれば、端部に開口部11を有する一方のルーバー材Aと、前記開口部11に挿入される受部20を有する他方のルーバー材Bと、を連結する構造であるため、押出成形では製作が困難な大型形材でも容易に製作することができ、また大型形材を押出成形する機械が不要であるため安価に製造することができる。特に、図1及び図2に示すように、建物躯体31に対して張り出す大型ルーバーパネルを容易に製作することができる。   Thus, according to this embodiment, the structure which connects one louver material A which has the opening part 11 in an edge part, and the other louver material B which has the receiving part 20 inserted in the said opening part 11 is connected. Therefore, it is possible to easily produce a large shape that is difficult to produce by extrusion molding, and it is possible to produce it inexpensively because a machine for extruding the large shape is not required. In particular, as shown in FIGS. 1 and 2, a large louver panel that protrudes from the building frame 31 can be easily manufactured.

また、一対の引掛部13の逆止爪13bと一対の引掛受部22とを係合させるだけでルーバー材10を連結できるので、接着剤を使用しなくても形材同士を容易に連結することができ、作業性がよい。   Moreover, since the louver material 10 can be connected only by engaging the check claws 13b of the pair of hook portions 13 and the pair of hook receiving portions 22, the shapes can be easily connected without using an adhesive. Can work, and workability is good.

また、前記一対の引掛部13の内側面13aは、奥に行くに従って互いに接近するように傾斜しているので、傾斜した引掛部13の内側面13aに沿って受部20を挿入することができ、形材の接合をスムーズに行うことができる。   In addition, since the inner side surfaces 13a of the pair of hooking portions 13 are inclined so as to approach each other as they go deeper, the receiving portion 20 can be inserted along the inner side surface 13a of the inclined hooking portion 13. It is possible to smoothly join the shape members.

また、他方のルーバー材Bの受部20は、一対の側辺部21の端部を平坦部25でつなぎ、一対の側辺部21に引掛受部22を設けた構成であるため、引掛受部22が必要以上に内側に撓まないように平坦部25が支持している。よって、負荷がかかるなどして形材が脱落しそうになった場合でも、引掛受部22が弾性変形しにくいので、引掛部13と引掛受部22との係合が外れ難くなっており、形材同士が脱落しないように確実に連結することができる。   Further, the receiving portion 20 of the other louver material B has a configuration in which the end portions of the pair of side portions 21 are connected by the flat portion 25 and the hook receiving portion 22 is provided on the pair of side portions 21. The flat portion 25 supports the portion 22 so as not to bend inward more than necessary. Therefore, even when the shape is likely to fall off due to a load or the like, the hook receiving portion 22 is not easily elastically deformed, so that the engagement between the hook portion 13 and the hook receiving portion 22 is difficult to disengage, It can connect reliably so that materials may not fall out.

しかも、引掛部13の先端が突き当て部23に当接するように形成されているため、この当接部においても2つの型材が互いに支持されているため、接合部10aのガタツキや緩みがない精度の高い連結が可能となる。   In addition, since the tip of the hooking portion 13 is formed so as to abut against the abutting portion 23, the two mold materials are also supported by this abutting portion, so that there is no backlash or looseness of the joint portion 10a. High connection is possible.

また、前記他方のルーバー材Bの受部20は、前記一対の引掛部13の内側面13aに当接する段差部24を備えているため、段差部24と引掛部13の内側面13aとが当接することで2つの型材が互いに支持される。このように2つの型材の支持箇所を増設することができるので、接合部10aのガタツキや緩みがない精度の高い連結を行うことができる。   Further, the receiving portion 20 of the other louver material B includes a stepped portion 24 that contacts the inner side surface 13a of the pair of hooking portions 13, so that the stepped portion 24 and the inner side surface 13a of the hooking portion 13 are in contact with each other. The two mold materials are supported by contacting each other. Thus, since the support location of two mold materials can be expanded, it is possible to perform highly accurate connection without rattling or loosening of the joint portion 10a.

また、前記一方のルーバー材Aに、前記一対の連結脚12の間に架橋するように補強壁15を設けたので、連結脚12が必要以上に開かないように補強することができる。よって、接合部のガタツキや緩みのない精度の高い連結を行うことができる。   Further, since the reinforcing wall 15 is provided on the one louver material A so as to be bridged between the pair of connecting legs 12, the connecting legs 12 can be reinforced so as not to open more than necessary. Therefore, it is possible to perform highly accurate connection without rattling or loosening of the joint.

しかも、ルーバー材10の接合部10aに一対の落下防止具取付部15c,25a(挿通孔)を互いに対向するように設け、前記一対の落下防止具取付部15c,25aを接続するように落下防止具Cを取り付けたので、建物から張り出す方向にルーバー材10を接合してルーバーパネル30を構成した際に、仮にルーバー材10の接合が外れた場合でもルーバー材10の落下を防止することができる。すなわち、安全にルーバー材10を接合してルーバーパネル30を構成することができるので、大きく張り出した形状の大型のルーバーパネル30を容易に構成でき、かつ、部品数や製造コストの増加を抑えることができる。   Moreover, a pair of fall prevention device attachment portions 15c, 25a (insertion holes) are provided in the joint portion 10a of the louver member 10 so as to face each other, and the fall prevention device attachment portions 15c, 25a are connected to each other to prevent the fall. Since the tool C is attached, when the louver panel 10 is configured by joining the louver material 10 in the direction protruding from the building, even if the louver material 10 is disconnected, the louver material 10 can be prevented from falling. it can. That is, since the louver panel 30 can be configured by safely joining the louver material 10, the large louver panel 30 having a large projecting shape can be easily configured, and the increase in the number of parts and the manufacturing cost can be suppressed. Can do.

また、ルーバー材10の接合部10aに一対の落下防止具取付部15c,25aを互いに対向するように設けた構造であるので、接合する2つのルーバー材10に設ける落下防止具取付部15c,25aを区別する必要がなく、2つのルーバー材10に同じ落下防止具取付部15c,25aを設ければよい。このため、ルーバー材10をいくつ連続して接合した場合でも、同じ落下防止具取付部15c,25aをルーバー材10の接合可能な両端部に設けるだけで、それぞれの接合部10aに落下防止構造を設けることができる。   Moreover, since it is the structure which provided a pair of fall prevention tool attachment parts 15c and 25a in the junction part 10a of the louver material 10 so as to oppose each other, the fall prevention tool attachment parts 15c and 25a provided in the two louver materials 10 to be joined. Need not be distinguished from each other, and the same drop preventer mounting portions 15c and 25a may be provided on the two louver members 10. For this reason, no matter how many louver members 10 are joined together, the same drop prevention device mounting portions 15c and 25a are provided at both end portions to which the louver material 10 can be joined, and each joint portion 10a is provided with a fall prevention structure. Can be provided.

また、前記一対の落下防止具取付部15c,25aとして一対の挿通孔15c,25aを設け、前記落下防止具Cは、前記一対の挿通孔15c,25aを貫通するボルト27(締結材)と、ボルト27に螺合するナット28(被締結材)と、ボルト27の軸部に外装されて前記一対の挿通孔15c,25aの間に配置される支持材26と、を備えるので、落下防止具取付部15c,25aの間に支持材26を挿入してボルト27とナット28とを締結するだけで落下防止構造を設けることができ、作業性が良い。また、2つのルーバー材A,Bに支持材26が当接して固定するため、接合部10aの締結度を増すことができる。
なお、図5に示すように、ルーバー材10の外側面に模様10bを施し、接合箇所が目立たないようにしてもよい。
Further, a pair of insertion holes 15c, 25a is provided as the pair of fall prevention tool mounting portions 15c, 25a, and the fall prevention tool C includes a bolt 27 (fastening material) penetrating the pair of insertion holes 15c, 25a, and Since it includes a nut 28 (fastened material) that is screwed into the bolt 27 and a support member 26 that is externally mounted on the shaft portion of the bolt 27 and disposed between the pair of insertion holes 15c and 25a, the fall prevention tool A fall prevention structure can be provided simply by inserting the support member 26 between the mounting portions 15c and 25a and fastening the bolt 27 and the nut 28, and the workability is good. Moreover, since the support material 26 contacts and is fixed to the two louver materials A and B, the fastening degree of the joint portion 10a can be increased.
In addition, as shown in FIG. 5, the pattern 10b may be given to the outer side surface of the louver material 10, and it may be made not to make a joining location conspicuous.

また、上記した実施形態においては支持材26を筒状としたが、支持材26の形状は筒状に限らない。すなわち、支持材26は、補強壁15と平坦部25とに当接して補強壁15及び平坦部25を安定的に支持できるものであればよい。   In the above-described embodiment, the support member 26 is cylindrical, but the shape of the support member 26 is not limited to a cylindrical shape. That is, the support member 26 only needs to be in contact with the reinforcing wall 15 and the flat portion 25 and stably support the reinforcing wall 15 and the flat portion 25.
