開口枠１０は、建物開口の縁に沿って配置される枠体であり、上下の横枠と、左右の縦枠とにより形成されている。図１、図２には、そのうちの１本の縦枠１１の断面が表れている。縦枠１１は見込み方向に並べられるように室外側の第一縦枠１２、及び室内側の第二縦枠１５を有し、当該第一縦枠１２と第二縦枠１５との間には断熱部材１３、１４が挟まれるように具備されている。また、第二縦枠１５には連結部材２０が取り付けられている。   The opening frame 10 is a frame body arranged along the edge of the building opening, and is formed by upper and lower horizontal frames and left and right vertical frames. 1 and 2 show a cross section of one of the vertical frames 11. The vertical frame 11 has a first vertical frame 12 on the outdoor side and a second vertical frame 15 on the indoor side so as to be arranged in the expected direction, and between the first vertical frame 12 and the second vertical frame 15, The heat insulating members 13 and 14 are provided so as to be sandwiched. A connecting member 20 is attached to the second vertical frame 15.

第一縦枠１２は、図１、図２に表れる断面において略矩形枠状の断面を有した長尺の部材であり、当該断面形状を概ね維持して紙面奥／手前方向に延在している。
第二縦枠１５は、図１、図２に表れる断面において、片１５ａ、片１５ｂ、及び片１５ｃにより略コ字状の断面が形成された長尺の部材である。断面コ字状の対向する片１５ａ、１５ｃのうち、第一縦枠１２側の片１５ａが、他方の片１５ｃより長く形成されている。 The first vertical frame 12 is a long member having a substantially rectangular frame-like cross section in the cross sections shown in FIGS. 1 and 2, and generally extends in the back / front direction of the paper while maintaining the cross-sectional shape. Yes.
The second vertical frame 15 is a long member in which a substantially U-shaped cross section is formed by the piece 15a, the piece 15b, and the piece 15c in the cross section shown in FIGS. Of the opposing pieces 15a, 15c having a U-shaped cross section, the piece 15a on the first vertical frame 12 side is formed longer than the other piece 15c.

連結部材２０、２０は、第二縦枠１５の長手方向（紙面奥／手前方向）に並列されて取り付けられる部材である。図３には連結部材２０、２０が第二縦枠１５に並列された姿勢を示し、図４には連結部材２０の平面図（図４（ａ））及び正面図（図４（ｂ））を示した。
図１、図２及び図４（ａ）からわかるように、連結部材２０は薄板が曲げられて形成されたような部材である。連結部材２０は、片２０ａ、２０ｂ、２０ｃ、２０ｄ、２０ｅ、２０ｆ、２０ｇを備えている。当該片において片２０ａ、片２０ｂ、及び片２０ｃでコ字状部２１が形成されている。また、片２０ｃを共有して該片２０ｃ、片２０ｄ、及び片２０ｅでさらにコ字状部２２が形成されている。当該コ字状部２２は、コ字状部２１と開口方向が逆であるように形成されている。加えて、片２０ｅを共有して片２０ｅ、片２０ｆ、及び片２０ｇによりさらなるコ字状部２３が形成されている。当該コ字状部２３は、コ字状部２１と同じ方向に開口している。 The connecting members 20 and 20 are members that are mounted in parallel in the longitudinal direction of the second vertical frame 15 (back of the paper surface / front side). FIG. 3 shows a posture in which the connecting members 20, 20 are arranged in parallel with the second vertical frame 15, and FIG. 4 shows a plan view (FIG. 4 (a)) and a front view (FIG. 4 (b)) of the connecting member 20. showed that.
As can be seen from FIGS. 1, 2 and 4A, the connecting member 20 is a member formed by bending a thin plate. The connecting member 20 includes pieces 20a, 20b, 20c, 20d, 20e, 20f, and 20g. In the piece, the U-shaped portion 21 is formed by the piece 20a, the piece 20b, and the piece 20c. Further, the U-shaped portion 22 is further formed by the piece 20c, the piece 20d, and the piece 20e sharing the piece 20c. The U-shaped portion 22 is formed so that the opening direction is opposite to the U-shaped portion 21. In addition, a further U-shaped portion 23 is formed by the piece 20e, the piece 20f, and the piece 20g sharing the piece 20e. The U-shaped part 23 opens in the same direction as the U-shaped part 21.

ここで、図４（ａ）にＡで示した長さは、ここに配置される固定部材３４が回動できないように保持することができる大きさに形成されている。すなわち、後述するようにここに配置されるボルト（固定部材３４）の頭部（固定端）３４ｂの幅（六角ボルトの六角部の対向面間距離。）と概ね同じ大きさに形成されている。
また、図４（ａ）にＢで示した長さは、ここに上記固定部材３４の固定端３４ｂが入ることができる大きさに形成されている。すなわち、後述するようにここに配置されるボルト（固定部材３４）の頭部（固定端）３４ｂの厚さ（六角ボルトの六角部の厚さ。）より大きく形成される。
すなわち、当該コ字状部２２の内側には、固定部材３４の固定端３４ｂが回動禁止に挿入できる。 Here, the length indicated by A in FIG. 4A is formed in such a size that the fixing member 34 arranged here can be held so as not to rotate. That is, as will be described later, it is formed to have approximately the same size as the width of the head (fixed end) 34b of the bolt (fixing member 34) disposed here (distance between the opposing surfaces of the hexagonal portions of the hexagonal bolt). .
Further, the length indicated by B in FIG. 4A is formed in such a size that the fixed end 34b of the fixing member 34 can enter here. That is, as will be described later, it is formed larger than the thickness (the thickness of the hexagonal portion of the hexagonal bolt) of the head (fixed end) 34b of the bolt (fixing member 34) arranged here.
That is, the fixed end 34 b of the fixing member 34 can be inserted into the U-shaped portion 22 so as not to rotate.

また、図４（ｂ）からわかるように、連結部材２０のうち、片２０ｄにはスリット２４、２５ｂが並列されるように設けられている。スリット２４は、一方が片２０ｄの端部にまで達し、ここに開口部２４ａを有している。また他方の端部は半円状に形成されている。ここでＣで示したスリット幅は、ここに配置される固定部材３４の連結軸３４ａ（ボルトのネジ部）の直径より大きく、かつ、固定部材３４の固定端３４ｂ（ボルトの頭部）を通すことができない大きさに形成されている。   Moreover, as can be seen from FIG. 4B, the slits 24 and 25 b are provided in parallel on the piece 20 d of the connecting member 20. One of the slits 24 reaches the end of the piece 20d, and has an opening 24a. The other end is formed in a semicircular shape. Here, the slit width indicated by C is larger than the diameter of the connecting shaft 34a (bolt thread portion) of the fixing member 34 disposed here, and the fixing end 34b (bolt head) of the fixing member 34 is passed through. It is formed in a size that can not be.

スリット２５ｂは、Ｆで示したスリット幅を有している。当該スリット幅Ｆは、ここに配置される固定部材３４の連結軸３４ａ（ボルトのネジ部）の直径より大きく、かつ、固定部材３４の固定端３４ｂ（ボルトの頭部）を通すことができない大きさに形成されている。従って、上記スリット幅Ｃと同じとしても良い。   The slit 25b has a slit width indicated by F. The slit width F is larger than the diameter of the connecting shaft 34a (bolt threaded portion) of the fixing member 34 disposed here, and the slit width F cannot pass the fixed end 34b (bolt head) of the fixing member 34. Is formed. Accordingly, the slit width C may be the same.

スリット２５ｂの一端側には、他のスリット２５ａが設けられ、スリット２５ｂに連続している。他のスリット２５ａは、スリット２５ｂのスリット２４側端部に設けられ、図４（ｂ）にＤで示した幅、及びＥで示した長さを有している。ここでＤの大きさは、上記説明したコ字状部２２の幅Ａと概ね同じである。また、Ｅで示した大きさは、ここに配置される固定部材３４がコ字状部２２の内側に挿入できる大きさとされている。例えば後述するようにここに配置されるボルト（固定部材）３４の頭部（固定端）３４ｂの最大幅（六角ボルトの六角である部分の対向する角間。）より大きく形成される。
すなわち、他のスリット２５ａにより、該他のスリット２５ａを通じてコ字状部２２に固定部材３４の固定端３４ｂを挿入することができるような形状、大きさとされている。 Another slit 25a is provided on one end side of the slit 25b and continues to the slit 25b. The other slit 25a is provided at the end of the slit 25b on the slit 24 side, and has a width indicated by D and a length indicated by E in FIG. Here, the size of D is substantially the same as the width A of the U-shaped portion 22 described above. Further, the size indicated by E is such that the fixing member 34 disposed here can be inserted inside the U-shaped portion 22. For example, as will be described later, it is formed larger than the maximum width of the head (fixed end) 34b of the bolt (fixed member) 34 disposed here (between the opposing corners of the hexagonal portion of the hexagon bolt).
That is, the other slit 25a is shaped and sized so that the fixed end 34b of the fixing member 34 can be inserted into the U-shaped portion 22 through the other slit 25a.

このような連結部材２０、２０は、図３からわかるように、第二縦枠１５の長手方向に２つ取り付けられる。当該取り付けの方法は特に限定されるものではないが、例えばネジ等の固定部材により行われる。より詳しくは図２からよくわかるように、連結部材２０は、第二縦枠１５のコ字状である内側に配置される。このとき、第二縦枠１５の片１５ｂに、片２０ｂ、２０ｆを面して接するように配置される。これにより、第二縦枠１５の片１５ｂと、連結部材２０のコ字状部２２とに囲まれる空間が形成される。   As can be seen from FIG. 3, two such connecting members 20, 20 are attached in the longitudinal direction of the second vertical frame 15. Although the method of the attachment is not particularly limited, for example, it is performed by a fixing member such as a screw. More specifically, as can be seen from FIG. 2, the connecting member 20 is disposed on the inner side of the second vertical frame 15 which is U-shaped. At this time, it arrange | positions so that the piece 20b, 20f may be faced and contacted to the piece 15b of the 2nd vertical frame 15. FIG. Thereby, a space surrounded by the piece 15b of the second vertical frame 15 and the U-shaped portion 22 of the connecting member 20 is formed.

断熱部材１３、１４は、第一縦枠１１と第二縦枠１５との間に配置される断熱性を有する部材であり、第一縦枠１１、第二縦枠１５の長手方向（図１の紙面奥手前方向）に延在して配置されている。これにより室内外の断熱性を向上させている。   The heat insulating members 13 and 14 are members having heat insulating properties disposed between the first vertical frame 11 and the second vertical frame 15, and the longitudinal directions of the first vertical frame 11 and the second vertical frame 15 (FIG. 1). (In front of the paper surface). Thereby, the indoor and outdoor heat insulation is improved.

Two sets of fixing members 34 and 35 are juxtaposed in a direction along the longitudinal direction of the wall member main body 31 (the back / front side of the drawing in FIGS. 1 and 2).
The wall side connecting member 33 is also provided at a position corresponding to the connecting member 20. Therefore, in this embodiment, the two wall side connecting members 33 and 33 are arranged in parallel in the longitudinal direction of the wall member main body 31 (the rear side / front side in FIGS. 1 and 2).

外壁材４０は建物の外壁を形成する板状のいわゆる壁パネルである。外壁材４０は通常に用いられるものを適用することが可能であり、特に限定されることはない。これには例えばＡＬＣパネルやＰＣパネルを挙げることができる。   The outer wall material 40 is a plate-shaped so-called wall panel that forms the outer wall of a building. As the outer wall member 40, a commonly used one can be applied and is not particularly limited. Examples thereof include an ALC panel and a PC panel.

上記した開口枠部材１において、開口枠１０と、壁部材３０とは例えば次のように組み合わされて施工され、さらに、外壁材４０が設けられる。図５、図６に施工方法の一例を説明するための図を示した。   In the opening frame member 1 described above, the opening frame 10 and the wall member 30 are constructed and combined as follows, for example, and an outer wall member 40 is further provided. The figure for demonstrating an example of the construction method to FIG. 5, FIG. 6 was shown.

はじめに、図５（ａ）に矢印Ｖで示したように、縦枠１１に壁部材３０を近づけて接触させる。このとき、ボルト（固定部材３４）、ナット（固定部材３５）は少し緩めておき、ボルト（固定部材３４）の頭部（固定端３４ｂ）と、壁側連結部材３３の片３３ｄとの間に少なくとも連結部材２０の片２０ｄの厚さよりも大きな隙間ができるようにしておく。また、図５（ｂ）に示したように２つの固定部材３４、３４の固定端３４ｂ、３４ｂうち、一方は、連結部材２０のスリット２４の開口部２４ａの上方に配置し、他方はスリット２５ａを貫通させてコ字状部２２の内側に挿入する。スリット２５ａは上記したように固定部材３４の固定端３４ｂを貫通させることができるので、当該配置が可能である。   First, as shown by the arrow V in FIG. 5A, the wall member 30 is brought close to and brought into contact with the vertical frame 11. At this time, the bolt (fixing member 34) and the nut (fixing member 35) are slightly loosened, and between the head (fixed end 34b) of the bolt (fixing member 34) and the piece 33d of the wall side connecting member 33. A gap larger than at least the thickness of the piece 20d of the connecting member 20 is formed. As shown in FIG. 5B, one of the fixed ends 34b, 34b of the two fixing members 34, 34 is disposed above the opening 24a of the slit 24 of the connecting member 20, and the other is the slit 25a. Is inserted through the U-shaped portion 22. Since the slit 25a can penetrate the fixed end 34b of the fixing member 34 as described above, this arrangement is possible.

次に図６に示したように壁部材３０を下げるように移動する。これにより固定部材３４、３４の固定端３４ｂ、３４ｂは連結部材２０のコ字状部２２内をスライドする。そして固定部材３４、３４の連結軸３４ａ、３４ａはスリット２４、２５ｂ内をスライドする。ここでスリット２４、２５ｂは、連結軸３４ａ、３４ａを通すことはできるが、固定端３４ｂ、３４ｂを通すことはできない構成になっている。これにより壁部材３０は開口枠１０の縦枠１１に保持される。   Next, as shown in FIG. 6, the wall member 30 is moved so as to be lowered. As a result, the fixed ends 34 b and 34 b of the fixing members 34 and 34 slide in the U-shaped portion 22 of the connecting member 20. The connecting shafts 34a and 34a of the fixing members 34 and 34 slide in the slits 24 and 25b. Here, the slits 24 and 25b can pass the connecting shafts 34a and 34a, but cannot pass the fixed ends 34b and 34b. As a result, the wall member 30 is held by the vertical frame 11 of the opening frame 10.

その後、固定部材３０の固定部材３５（ナット）を回動させて、開口枠１０と壁部材３０とを強固に固定する。このとき、上記したように、固定部材３４の固定端３４ｂは連結部材２０のコ字状部２２の内側で回動できないように形成されている。従って、固定部材３５（ナット）を回動させるだけで、固定部材３４、３５による固定をすることが可能である。   Thereafter, the fixing member 35 (nut) of the fixing member 30 is rotated to firmly fix the opening frame 10 and the wall member 30. At this time, as described above, the fixed end 34 b of the fixing member 34 is formed so as not to rotate inside the U-shaped portion 22 of the connecting member 20. Therefore, the fixing members 34 and 35 can be fixed only by rotating the fixing member 35 (nut).

その後、図１に示した構造となるように、外壁材４０及び、目地部のシール４５、４６を形成すればよい。   Thereafter, the outer wall member 40 and the joint seals 45 and 46 may be formed so as to have the structure shown in FIG.

以上のように、本発明の開口縁構造によれば、容易に壁部材３０を開口枠１０に固定して、開口縁構造を形成することが可能である。また開口枠１０に固定部材３４の固定端３４ｂ（ボルトの頭部）を操作するための孔等を設ける必要もなく施工性に優れたものとすることができる。   As described above, according to the opening edge structure of the present invention, it is possible to easily fix the wall member 30 to the opening frame 10 to form the opening edge structure. Further, there is no need to provide a hole or the like for operating the fixed end 34b (bolt head) of the fixing member 34 in the opening frame 10, and the workability can be improved.
