Description

本発明は、連窓構造に関する。 The present invention relates to a continuous window structure.

従来、建物の開口部において、隣接する二つの窓部の間に、方立のような連結部が配置された連窓構造が知られている。連窓構造では、窓部のそれぞれの枠体と、連結部とが、連結部に固定された板状の固定部材を介して連結されている。防火性を高めるため、この固定部材と枠体とを、互いに係合可能な係合部により接続することで、高熱に曝された場合の変形に耐えうる構成とされている(例えば、特許文献1参照)。 BACKGROUND ART Conventionally, there has been known a continuous window structure in which a connecting portion such as a cuboid is arranged between two adjacent window portions in an opening of a building. In the continuous window structure, each frame of the window portion and the connecting portion are connected via a plate-shaped fixing member fixed to the connecting portion. In order to improve fireproofness, the fixing member and the frame body are connected to each other by engaging portions that can engage with each other, so that they can withstand deformation when exposed to high heat (for example, Patent Document 1). 1).

枠体と連結部とを確実に連結することで、火炎が貫通することは抑制できるが、連結部自体は高熱に曝される。連結部自体の耐火性能を向上させるために、連結部の屋内側に耐火ボードが配置される。 Although it is possible to prevent the flame from penetrating by surely connecting the frame and the connecting portion, the connecting portion itself is exposed to high heat. In order to improve the fireproof performance of the connecting part itself, a fireproof board is arranged on the indoor side of the connecting part.

係合外方辺部123は、係合片部122の途中から左右方向外側に立ち上がって見込方向外側へ延びると共に、更に左右方向外側に向かう。従って、係合片部122の延出端部と係合外方辺部123とは、屋外側へ向かって広がるV字形状部により構成されており、このため、係合片部122の延出端部と係合外方辺部123との間には、これらにより形成されるV字形状の溝が形成されている。係合外方辺部123の屋外側の端部は、係合片部122の屋外側の端部よりも、屋外側へ向かって長く突出している。
図3に示すように、固定部材側係合部12は、屋外側に位置している内側縦枠24の枠体側係合部240−1における縦枠見込延出部242−1の外面、すなわち連結部10に近い内側縦枠24の面の側に係合片部122の延出端部(図3における係合片部122の上端部)が位置し、内側縦枠24の枠体側係合部240−1における縦枠見込延出部242の内面、すなわち内側縦枠24の見込面側(連結部10から離間した面の側)に係合外方辺部123が位置するように枠体側係合部240−1に係合する。
The fixing member side engagement portion 12 is formed at one of the longitudinal end portions of the plate-shaped portion 11, that is, at the outdoor end portion of the plate-shaped portion 11 in the longitudinal direction. The fixed member side engagement portion 12 has a rising portion 121, an engagement piece portion 122, and an engagement outer side portion 123.
The rising portion 121 is attached to the connecting portion 10 and rises outward in the left-right direction from the end portion of the plate-shaped portion 11 in the expected direction toward the frame-side engagement portion 240 side.
The engagement piece portion 122 extends from the end of the rising portion 121 in the lengthwise direction of the plate-shaped portion 11 to the outside in the lengthwise direction of the plate-shaped portion 11 while being attached to the connecting portion 10.
The engagement outer side portion 123 rises from the middle of the engagement piece portion 122 to the outside in the left-right direction, extends outward in the expected direction, and further extends to the outside in the left-right direction. Therefore, the extending end portion of the engaging piece 122 and the engaging outer side portion 123 are formed by the V-shaped portion that expands toward the outdoor side. A V-shaped groove formed by these is formed between the end portion and the engagement outer side portion 123. The outdoor side end of the engaging outer side portion 123 projects longer toward the outdoor side than the outdoor side end of the engaging piece 122.
As shown in FIG. 3, the fixed member side engaging portion 12 is the outer surface of the vertical frame expected extension portion 242-1 in the frame body side engaging portion 240-1 of the inner vertical frame 24 located on the outdoor side, that is, The extended end portion of the engagement piece portion 122 (the upper end portion of the engagement piece portion 122 in FIG. 3) is located on the side of the surface of the inner vertical frame 24 close to the coupling portion 10, and the inner side vertical frame 24 is engaged with the frame body side.

Therefore, the fixing member side engaging portion 12 of the anchor 1 can reliably press the airtight material 35 against the outer cover 3 via the inner vertical frame 24.

また、図3に示すように、見込方向における、固定部材側係合部12の係合外方辺部123の端部と、内側縦枠24の縦枠見付延出部241−1との間には、隙間S2が形成されている。これにより、縦枠見込延出部242−1が固定部材側係合部12に係合する前に、係合外方辺部123の端部と縦枠見付延出部241−1とが当接することを防ぐことが可能となり、縦枠見込延出部242−1と固定部材側係合部12との係合を確実とすることが可能となる。 Further, as shown in FIG. 3, the end portion of the engagement outer side portion 123 of the fixed member side engagement portion 12 and the vertical frame found extension portion 241-1 of the inner vertical frame 24 in the expected direction. A gap S2 is formed between them. As a result, before the vertical frame prospective extending portion 242-1 engages with the fixed member side engaging portion 12, the end of the engaging outer side portion 123 and the vertical frame apparent extending portion 241-1 are separated. It is possible to prevent the contact, and it is possible to ensure the engagement between the vertical frame expected extension portion 242-1 and the fixed member side engagement portion 12.

また、図3に示すように、左右方向における、外側カバー3のカバー部材固定部33、及び、連結部10の見込面と、固定部材側係合部12の係合片部122との間には、隙間S3が形成されている。これにより、固定部材側係合部12が連結部10及びカバー部材固定部33から左右方向に離間し、後述のように、内側縦枠24の縦枠見込延出部242−1を固定部材側係合部12に係合させる際に、当該係合を容易となる。 Further, as shown in FIG. 3, between the cover member fixing portion 33 of the outer cover 3 and the projected surface of the connecting portion 10 and the engaging piece portion 122 of the fixing member side engaging portion 12 in the left-right direction.

As shown in FIG. 3, the fixing portion 13 is fixed to the connecting portion 10 by engaging the anchor 1 with the inner vertical frame 24 being moved to the outdoor side along the connecting portion 10 as described later. When this happens, the anchor 1 is immovable with respect to the connecting portion 10 so as to abut against the indoor-side finding surface that is the end surface on the indoor side of the connecting portion 10 and prevent the anchor 1 from moving further to the outdoor side. .. For this reason, the range in which the anchor 1 can move toward the outdoor side is up to the position on the indoor side with respect to the airtight member 35, and the anchor 1 and the airtight member 35 are not in contact with each other. Further, by pulling the fixing portion 13 toward the indoor side, it is possible to easily pull out the anchor 1 to a position on the indoor side before fixing the inner vertical frame 24 to the anchor 1.

次に、アンカー1の固定部13を屋外側へ押すことにより、アンカー1は、屋外側へ移動する。このとき、固定部材側係合部12には、内側縦枠24の縦枠見込延出部242が係合しているため、アンカー1の、屋外側へ移動に伴い、内側縦枠24も屋外側へ移動する。 Next, by pushing the fixing portion 13 of the anchor 1 to the outdoor side, the anchor 1 moves to the outdoor side. At this time, since the vertical frame prospective extension 242 of the inner vertical frame 24 is engaged with the fixed member side engaging portion 12, the inner vertical frame 24 also moves along with the movement of the anchor 1 to the outdoor side. Move to the outside.

そして、アンカー1が更に移動することにより、内側縦枠24の屋外側見付面2401が気密材35に当接し気密材35を押圧する。これと同時に、屋内側の内側縦枠24の縦枠見込延出部242−2が、固定部材屋内側係合部72の係合内方片部722と係合外方辺部723とにより形成される、屋内側へ向かって開口するV字形状の開口に係合する。これにより、屋外側における内側縦枠24の部分は、固定部材側係合部12に、内側縦枠24の縦枠見込延出部242−1が係合しており、屋内側における内側縦枠24の部分は、固定部材屋内側係合部72の係合内方片部722と係合外方辺部723とにより形成される、屋内側へ向かって開口するV字形状の開口に係合するため、アンカー1を介して、連結部10に内側縦枠24が連結される。そして接続部材61及び取付け鋼材62を介して内側縦枠24の屋内側の見付面の部分が連結部10に固定されて、内側縦枠24は連結部10から外れないように固定される。 When the anchor 1 further moves, the outdoor-side finding surface 2401 of the inner vertical frame 24 abuts the airtight material 35 and presses the airtight material 35. At the same time, the vertical frame prospective extension 242-2 of the inner vertical frame 24 on the indoor side is formed by the engagement inner piece 722 and the engagement outer side portion 723 of the fixed member indoor engagement section 72. Is engaged with a V-shaped opening that opens toward the indoor side. As a result, in the portion of the inner vertical frame 24 on the outdoor side, the fixed frame side engaging portion 12 is engaged with the vertical frame prospective extension portion 242-1 of the inner vertical frame 24, and the inner vertical frame on the indoor side. The portion 24 is engaged with a V-shaped opening that opens toward the indoor side, which is formed by the engaging inner piece 722 and the engaging outer side portion 723 of the fixing member indoor engaging portion 72. Therefore, the inner vertical frame 24 is connected to the connecting portion 10 via the anchor 1. Then, the indoor-side finding surface portion of the inner vertical frame 24 is fixed to the connecting portion 10 via the connecting member 61 and the mounting steel material 62, and the inner vertical frame 24 is fixed so as not to come off from the connecting portion 10.

本実施形態によれば、以下の効果が奏される。
本実施形態では、見込方向に沿った連結部10の側面(見込面)に沿って見込方向に移動可能に連結部10に支持され、見込方向に移動することにより内側縦枠24に係合する第1係合部材としてのアンカー1と、アンカー1とは別部材で構成され、連結部10に対して移動不能に固定され、枠体2の内側縦枠24に係合する第2係合部材としての屋内側アンカー7と、を備える。アンカー1及び屋内側アンカー7が内側縦枠24に係合することにより、内側縦枠24が連結部10に固定される。
According to this embodiment, the following effects are exhibited.
In the present embodiment, the connecting portion 10 is supported movably in the prospective direction along the side surface (prospecting surface) of the joint portion 10 along the prospective direction, and engages with the inner vertical frame 24 by moving in the prospective direction.

また、本実施形態においては、内側縦枠24には、内側縦枠24を連結部10に対してビスで固定するための孔が形成されていない。このため、内側縦枠24における水密性を高めることが可能となる。
また、見込方向における内側縦枠24の屋外側の部分がアンカー1に係合し、見込方向における内側縦枠24の屋内側の部分が屋内側アンカー7に係合して、内側縦枠24がアンカー1及び屋内側アンカー7を介して連結部10に固定される。このため、アンカー1を見込方向に移動可能な構成とすることができ、気密材等に内側縦枠24を押し付けることが可能となる。
Further, in the present embodiment, the inner vertical frame 24 is not provided with a hole for fixing the inner vertical frame 24 to the connecting portion 10 with a screw. Therefore, the watertightness of the inner vertical frame 24 can be enhanced.
Further, the outdoor side portion of the inner vertical frame 24 in the prospective direction engages with the anchor 1, the indoor side portion of the inner vertical frame 24 in the prospective direction engages with the indoor side anchor 7, and the inner vertical frame 24 becomes It is fixed to the connecting portion 10 via the anchor 1 and the indoor anchor 7. Therefore, the anchor 1 can be configured to be movable in the projected direction, and the inner vertical frame 24 can be pressed against the airtight material or the like.

また、本実施形態においては、連結部10の屋外側の見付面側には外側カバー3が配置され、見込方向における屋内側のアンカー1の端部が屋外側へ押されることにより、アンカー1は、見込方向における内側縦枠24の屋外側の部分を介して気密材35を外側カバー3に押し付ける。このため、外側カバー3と内側縦枠24との間の水密性を高めることが可能となる。 Further, in the present embodiment, the outer cover 3 is arranged on the outdoor-side finding surface side of the connecting portion 10, and the end portion of the indoor-side anchor 1 in the prospective direction is pushed to the outdoor side, whereby the anchor 1 Presses the airtight material 35 against the outer cover 3 via the outdoor side portion of the inner vertical frame 24 in the expected direction. Therefore, the watertightness between the outer cover 3 and the inner vertical frame 24 can be enhanced.

また、本実施形態においては、左右方向において、固定部材側係合部12の係合片部122と、連結部10との間には隙間S3が形成されている。このため、固定部材側係合部12が連結部10及びカバー部材固定部33から左右方向に離間する。この結果、内側縦枠24の縦枠見込延出部242−1を固定部材側係合部12に係合させる際に、係合を容易とすることができる。 Further, in the present embodiment, a gap S3 is formed between the engaging piece 122 of the fixed member side engaging portion 12 and the connecting portion 10 in the left-right direction. Therefore, the fixing member side engaging portion 12 is separated from the connecting portion 10 and the cover member fixing portion 33 in the left-right direction. As a result, when the vertical frame prospective extension 242-1 of the inner vertical frame 24 is engaged with the fixed member side engaging portion 12, the engagement can be facilitated.

Next, a second embodiment of the present invention will be described with reference to FIGS. 10 to 16C. FIG. 10 is a vertical cross-sectional view of the inner vertical frame 24 and the inner cover 6 in the vicinity of the connecting portion 10 of the continuous window 100A, with the illustration thereof omitted. FIG. 11 is a cross-sectional view in the vicinity of the connecting portion 10 of the continuous window 100A. FIG. 12 is a front view showing the anchor 1A. FIG. 13 is a side view showing the anchor 1A. FIG. 14 is a front view showing the lower anchor 7A. FIG. 15 is a side view showing the lower anchor 7A.
In the continuous window structure according to the second embodiment of the present invention, the configuration of the anchor 1A is different from the configuration of the anchor 1 in the first embodiment. Moreover, it differs from the first embodiment in that a lower anchor 7A is provided in place of the indoor anchor 7 in the first embodiment. The configuration of each part other than this is the same as that of the continuous window structure according to the first embodiment. The same components as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

図12等に示すように、アンカー1Aは、板状部11Aと、固定部材側係合部12Aと、固定部13Aと、を有する。 As shown in FIG. 12 and the like, the anchor 1A has a plate-shaped portion 11A, a fixing member side engaging portion 12A, and a fixing portion 13A.

板状部11Aは、略長方形の板体であり、連結部10に取り付けられた状態で、連結部10の見込面に沿って延びるように配置される。板状部11Aにおける幅方向(図12における上下方向)における中央位置には、見込方向に一致する板状部11Aの長手方向に延びる長孔111Aが、板状部11Aの長手方向における中央を挟んで2つ形成されている。長孔111Aには、連結部10に固定されたネジが貫通する。 The plate-shaped portion 11A is a substantially rectangular plate body, and is arranged so as to extend along the projected surface of the connecting portion 10 when attached to the connecting portion 10. At a central position in the width direction (vertical direction in FIG. 12) of the plate-shaped portion 11A, an elongated hole 111A extending in the longitudinal direction of the plate-shaped portion 11A that coincides with the expected direction sandwiches the center of the plate-shaped portion 11A in the longitudinal direction. Two are formed. A screw fixed to the connecting portion 10 passes through the long hole 111A.

長孔111Aが形成されている板状部11Aの部分は、それぞれ段部112A、113Aを有している。段部112A、113Aは、長孔111Aの長手方向における中央位置の板状部11Aの部分に形成されており、この段部112A、113Aを堺として、板状部11Aの屋内側の部分は、板状部11Aの屋外側の部分に対して、連結部10に近い位置関係となるように構成されている。このため、段部112A、113Aを堺とした板状部11Aの屋内側の部分と連結部10との間には、図11に示すように、隙間が形成されている。段部112Aの屋内寄りの部分には、連結部10から離間するように突出する突起115Aが設けられている。従って、ネジが長孔111Aの長手方向において相対的に板状部11Aに対して長孔111A内を移動することにより、アンカー1Aは、連結部10に対して相対的に見込方向へ移動する。このとき、ネジが段部112Aによる段差の突起115Aに当接し、突起115Aよりも屋内側の板状部11Aの部分が、板状部11Aと連結部10との間に形成された隙間を縮めるようにして撓み、ネジが突起115Aを乗り越えることによりアンカー1Aが移動することになるため、突起115Aよりも屋内側に位置しているネジが、長孔111A内で相対的に移動することを防止し、意図せずアンカー1Aが屋外側へ移動して、アンカー1A及び下側アンカー7Aと、内側縦枠24と、の係合が解除されることを抑えることが可能である。 The portion of the plate-shaped portion 11A in which the long hole 111A is formed has step portions 112A and 113A, respectively. The step portions 112A and 113A are formed in the portion of the plate-shaped portion 11A at the center position in the longitudinal direction of the long hole 111A, and with the step portions 112A and 113A as a sakai, the portion of the plate-shaped portion 11A on the indoor side is The plate-like portion 11A is configured to have a positional relationship close to the connecting portion 10 with respect to the outdoor side portion. Therefore, as shown in FIG. 11, a gap is formed between the connecting portion 10 and the indoor portion of the plate-shaped portion 11A having the stepped portions 112A and 113A as a sakai. A projection 115</b>A protruding so as to be separated from the connecting portion 10 is provided at a portion of the step portion 112</b>A closer to the indoor. Therefore, when the screw moves in the long hole 111A relative to the plate-shaped portion 11A in the longitudinal direction of the long hole 111A, the anchor 1A moves in the prospective direction relative to the connecting portion 10. At this time, the screw abuts the stepped protrusion 115A formed by the step 112A, and the portion of the plate-shaped portion 11A on the indoor side of the protrusion 115A shrinks the gap formed between the plate-shaped portion 11A and the connecting portion 10. In this way, the anchor 1A moves as the screw bends and moves over the protrusion 115A, so that the screw located on the indoor side of the protrusion 115A is prevented from moving relatively in the long hole 111A. However, it is possible to prevent the anchor 1A from unintentionally moving to the outdoor side and releasing the engagement between the anchor 1A and the lower anchor 7A and the inner vertical frame 24.

固定部材側係合部12Aは、板状部11Aの長手方向の端部の一方、即ち、板状部11Aの長手方向の屋外側の端部に形成される。固定部材側係合部12Aは、立ち上がり部121Aと、係合片部122Aと、係合外方辺部123Aと、を有する。
立ち上がり部121Aは、連結部10に取り付けられた状態で、板状部11Aの見込方向における端部から、左右方向外側に立ち上がって枠体側係合部240側へ向かう。
係合片部122Aは、立ち上がり部121Aの先端から板状部11Aの長手方向に、連結部10に取り付けられた状態で屋外側へ延びる。
係合外方辺部123Aは、係合片部122Aの屋外側の端部から、連結部10から離れるように傾斜して延びる折れ曲がった部分により構成されている。
The fixing member side engagement portion 12A is formed at one of the longitudinal end portions of the plate-shaped portion 11A, that is, at the outdoor end portion of the plate-shaped portion 11A in the longitudinal direction. The fixed member side engaging portion 12A has a rising portion 121A, an engaging piece portion 122A, and an engaging outer side portion 123A.
The rising portion 121A is attached to the connecting portion 10 and rises outward in the left-right direction from the end portion of the plate-shaped portion 11A in the expected direction toward the frame-side engaging portion 240 side.
The engagement piece portion 122A extends from the tip of the rising portion 121A to the outdoor side in the longitudinal direction of the plate-shaped portion 11A while being attached to the connecting portion 10.
The engagement outer side portion 123A is configured by a bent portion that extends from the end of the engagement piece portion 122A on the outdoor side in an inclined manner so as to be separated from the coupling portion 10.

固定部13Aは、固定部材側係合部12Aを有する板状部11Aの長手方向における一端部に対する板状部11Aの他端部から、板状部11Aの長手方向に直交するように延びる板状の部分であり、板状部11Aの他端部が、連結部10から離れるように折り曲げられた離間傾斜部131Aと、更に他端寄りの部分が連結部10に近づくように折り曲げられた形状の延出部132Aと、を有している。固定部13Aの延出部132Aは、図3に示すように、後述のように内側縦枠24が連結部10に沿って屋外側へ移動させられて、アンカー1A及び下側アンカー7Aに係合して連結部10に対して固定されたときに、接続部材61と、連結部10との間に配置されて、連結部10の屋内側の端面である屋内側見付面103と対向して配置され、延出部132Aと屋内側見付面103とは、当接し合うか又は離間している。これにより、図11に示すように、一対のアンカー1Aの延出部132Aの間には、連結部10の屋内側の部分で隠された隙間が形成されているが、この隙間に皿ネジ(皿ビス)615の頭部が配置されて、皿ネジ615は接続部材61を連結部10に固定する。このように、皿ネジ615が締められて接続部材61が連結部10に固定されることにより、接続部材61は内側縦枠24を屋外側へ押して、内側縦枠24の縦枠見付延出部241−1の屋外側面は、気密材35を押圧する。 The fixing portion 13A has a plate shape extending from one end of the plate-shaped portion 11A having the fixing member side engaging portion 12A in the longitudinal direction to the other end of the plate-shaped portion 11A so as to be orthogonal to the longitudinal direction of the plate-shaped portion 11A. Of the plate-shaped portion 11A, the other end portion of the plate-shaped portion 11A is bent so as to be separated from the connecting portion 10, and the separated inclined portion 131A is further bent so that a portion closer to the other end is closer to the connecting portion 10. And an extension portion 132A. As shown in FIG. 3, the extending portion 132A of the fixed portion 13A engages with the anchor 1A and the lower anchor 7A by moving the inner vertical frame 24 to the outdoor side along the connecting portion 10 as described later. When fixed to the connecting portion 10, the connecting member 61 and the connecting portion 10 are arranged so as to face the indoor-side finding surface 103 which is the indoor end surface of the connecting portion 10. The extending portion 132A and the indoor-side finding surface 103 are arranged in contact with each other or separated from each other. Thereby, as shown in FIG. 11, a gap hidden by the indoor portion of the connecting portion 10 is formed between the extending portions 132A of the pair of anchors 1A.

次に、連窓100Aの組み立てにおける連結部10への内側縦枠24の固定について説明する。図16Aは、連窓100Aの連結部10に内側縦枠24を固定する前の様子を示す断面図である。図16Bは、連窓100Aの連結部10に内側縦枠24を固定する位置へ内側縦枠24を移動させた様子を示す断面図である。図16Cは、連窓100Aの連結部10への内側縦枠24の固定に際して下側アンカー7Aを移動させて、内側縦枠24を連結部10に対して固定させた様子を示す断面図である。 Next, fixing the inner vertical frame 24 to the connecting portion 10 in assembling the continuous window 100A will be described. FIG. 16A is a cross-sectional view showing a state before fixing the inner vertical frame 24 to the connecting portion 10 of the continuous window 100A. FIG. 16B is a cross-sectional view showing a state where the inner vertical frame 24 is moved to a position where the inner vertical frame 24 is fixed to the connecting portion 10 of the continuous window 100A. FIG. 16C is a cross-sectional view showing a state in which the lower anchor 7A is moved to fix the inner vertical frame 24 to the connecting portion 10 when the inner vertical frame 24 is fixed to the connecting portion 10 of the continuous window 100A. ..

内側縦枠24を連結部10に固定する際には、先ず、図16Aに示すアンカー1Aのように、アンカー1Aを連結部10に対して、最も見込方向における屋内側へ移動させる。次に、内側縦枠24を左右方向に沿って連結部10に接近させてゆき、内側縦枠24の縦枠見込延出部242−1を係合内方片部722Aに当接させる。そして、このように当接した状態を維持したまま、内側縦枠24を屋外側へ移動させてゆき、図16Bに示すように、縦枠見付延出部241−1を気密材35に当接させる。 When fixing the inner vertical frame 24 to the connecting portion 10, first, as with the anchor 1A shown in FIG. 16A, the anchor 1A is moved relative to the connecting portion 10 toward the indoor side in the most probable direction. Next, the inner vertical frame 24 is moved closer to the connecting portion 10 along the left-right direction, and the vertical frame prospective extension 242-1 of the inner vertical frame 24 is brought into contact with the engaging inner piece 722A. Then, while maintaining such a state of contact, the inner vertical frame 24 is moved to the outdoor side, and as shown in FIG. 16B, the vertical frame found extending portion 241-1 is brought into contact with the airtight material 35.

The rotation of the portion 241-1 as the center of rotation (the lower end of the inner vertical frame 24 in FIG. 16B rotates to the right in the figure) is prevented and rotation is stopped. As a result, the inner vertical frame 24 can be reliably brought into contact with the airtight member 35.

次に、図16Cに示すように、アンカー1Aの固定部13Aを屋外側へ押すことにより、アンカー1Aは、屋外側へ移動する。 Next, as shown in FIG. 16C, by pushing the fixing portion 13A of the anchor 1A to the outdoor side, the anchor 1A moves to the outdoor side.

そして、更にアンカー1Aが移動することにより、係合片部122Aが縦枠見込延出部242−1に当接した状態となり、縦枠見込延出部242−1は、左右方向において、係合片部122Aと係合内方片部722Aとにより挟まれた状態となる。このとき、前述のように、縦枠見込延出部242−1が挿入される係合片部122Aと係合内方片部722Aとの間の隙間の幅は、縦枠見込延出部242−1が挿入されていないときには、縦枠見込延出部242−1の板厚よりも狭いため、縦枠見込延出部242−1は、係合内方片部722Aの存在により係合片部122Aを、左右方向において係合内方片部722Aから離間する方向へ押圧し、係合片部122Aは撓んでいる。また、縦枠見込延出部242−2が離間傾斜部131Aに当接した状態となり、縦枠見込延出部242−2は、左右方向において、離間傾斜部131Aと係合片部732Aとにより挟まれた状態となる。このとき、前述のように、縦枠見込延出部242−2が挿入される離間傾斜部131Aと係合片部732Aとの間の隙間の幅は、縦枠見込延出部242−2が挿入されていないときには、縦枠見込延出部242−2の板厚よりも狭いため、縦枠見込延出部242−2は、離間傾斜部131Aの存在により係合片部732Aを、左右方向において離間傾斜部131Aから離間する方向へ押圧し、係合片部732Aは撓んでいる。これにより、アンカー1A及び下側アンカー7Aを介して、連結部10に内側縦枠24が連結され固定される。 Then, as the anchor 1A further moves, the engagement piece portion 122A comes into contact with the vertical frame expected extension portion 242-1, and the vertical frame expected extension portion 242-1 engages in the left-right direction. It is in a state of being sandwiched between the piece 122A and the engaging inner piece 722A. At this time, as described above, the width of the gap between the engagement piece portion 122A into which the vertical frame expected extension portion 242-1 is inserted and the engagement inner piece portion 722A is equal to the vertical frame expected extension portion 242. When -1 is not inserted, since the plate thickness of the vertical frame expected extension portion 242-1 is narrower, the vertical frame expected extension portion 242-1 has the engagement piece 722A due to the presence of the engagement inner piece portion 722A. The portion 122A is pressed in the left-right direction in a direction away from the engagement inner piece portion 722A, and the engagement piece portion 122A is bent. Further, the vertical frame prospective extension part 242-2 is in contact with the separation inclined part 131A, and the vertical frame prospective extension part 242-2 is formed by the separation inclined part 131A and the engaging piece part 732A in the left-right direction. It will be sandwiched. At this time, as described above, the width of the gap between the separation inclined portion 131A into which the vertical frame prospective extension portion 242-2 is inserted and the engagement piece portion 732A is equal to the vertical frame prospective extension portion 242-2. When not inserted, since the plate thickness of the vertical frame expected extension portion 242-2 is narrower, the vertical frame expected extension portion 242-2 causes the engagement piece portion 732A to move in the left-right direction due to the presence of the separation inclined portion 131A. , The engaging piece 732A is bent by pressing in the direction away from the separating inclined portion 131A. As a result, the inner vertical frame 24 is connected and fixed to the connecting portion 10 via the anchor 1A and the lower anchor 7A.

本実施形態においては、内側縦枠24は、第1係合部材としてのアンカー1Aと第2係合部材としての下側アンカー7Aとにより挟まれた状態とされることにより、連結部10に固定される。このため、アンカー1Aと下側アンカー7Aとで内側縦枠24に係合するため、係合を容易且つ強固とすることが可能となる。 In the present embodiment, the inner vertical frame 24 is fixed to the connecting portion 10 by being sandwiched by the anchor 1A as the first engaging member and the lower anchor 7A as the second engaging member. To be done. Therefore, since the anchor 1A and the lower anchor 7A engage with the inner vertical frame 24, the engagement can be made easy and strong.
