右中骨１４０及び左中骨１５０が上枠本体１１４の底面１１３にビス２６０を用いて固定される。上枠本体１１４の底面１１３と右中骨１４０及び左中骨１５０との間に、エチレン・プロピレン・ジエンゴム（ＥＰＤＭ）から成るシーラー２７５が設けられる。シーラー２７５は、底面１１３と右中骨１４０及び左中骨１５０とから所定の圧力を受けてこれらに密着し、底面１１３と右中骨１４０及び左中骨１５０との間を止水する。 The right middle bone 140 and the left middle bone 150 are fixed to the bottom surface 113 of the upper frame main body 114 using screws 260. A sealer 275 made of ethylene / propylene / diene rubber (EPDM) is provided between the bottom surface 113 of the upper frame main body 114 and the right and left middle bones 140 and 150. The sealer 275 receives a predetermined pressure from the bottom surface 113, the right middle bone 140, and the left middle bone 150 and is in close contact therewith, and stops water between the bottom surface 113 and the right middle bone 140 and the left middle bone 150.
上側のカーテンウォールユニット１００の右中骨１４０の下端、左中骨１５０の下端１５６ａ、右下枠１８０、及び左下枠１９０は、嵌合凹溝１１７内に高さ方向略中央まで進入する。そして、右下枠１８０及び左下枠１９０は止水ゴム２７４と接触する。これにより、右中骨１４０の下端、左中骨１５０の下端１５６ａ、右下枠１８０、及び左下枠１９０とスプライサー２７０の内底２７１との間に、上枠１１０の幅方向全長に渡って走る空間（第２等圧空間部）１５７ができる。他方、上側のカーテンウォールユニット１００の右中骨１４０の下端及び左中骨１５０の下端１５６ｂは、嵌合凹溝１１７内に進入せず、板状部１１５及び上枠本体１１４の頂面に接触せず、板状部１１５及び上枠本体１１４の頂面から所定の間隔を空けた位置に置かれる。これにより、右中骨１４０の下端及び左中骨１５０の下端１５６ｂと上枠１１０との間に空間、つまり隙間ができる。 The lower end of the right middle bone 140, the lower end 156a of the left middle bone 150, the lower right frame 180, and the lower left frame 190 of the upper curtain wall unit 100 enter the fitting groove 117 to the approximate center in the height direction. The lower right frame 180 and the lower left frame 190 are in contact with the water blocking rubber 274. Thus, the upper frame 110 runs across the entire length in the width direction between the lower end of the right middle bone 140, the lower end 156a of the left middle bone 150, the lower right frame 180, and the lower left frame 190 and the inner bottom 271 of the splicer 270. A space (second isobaric space) 157 is formed. On the other hand, the lower end of the right middle bone 140 and the lower end 156b of the left middle bone 150 of the upper curtain wall unit 100 do not enter the fitting groove 117 and contact the top surfaces of the plate-like portion 115 and the upper frame main body 114. Without being placed, the plate-like portion 115 and the top surface of the upper frame main body 114 are placed at positions spaced apart from each other by a predetermined distance. Thereby, a space, that is, a gap is formed between the lower end of the right middle bone 140 and the lower end 156b of the left middle bone 150 and the upper frame 110.
図４を参照すると、右中骨１４０と左中骨１５０は、互いに向けて開口するコの字型の断面を有する。右中骨１４０は、右中骨１４０の全長に渡って開口の縁から突出する２枚の嵌合突起１４３を有する。右中骨１４０と左中骨１５０とを、互いの開口を対向させるように組み合わせたとき、２枚の嵌合突起１４３は、左中骨１５０の開口に向けて突出して左中骨１５０の開口の縁１５８、１５９と係合する。これにより、右中骨１４０と左中骨１５０との間に中空部（第１等圧空間部）２８０が形成される。 Referring to FIG. 4, the right middle bone 140 and the left middle bone 150 have a U-shaped cross section that opens toward each other. The right middle bone 140 has two fitting protrusions 143 that project from the edge of the opening over the entire length of the right middle bone 140. When the right middle bone 140 and the left middle bone 150 are combined so that their openings face each other, the two fitting protrusions 143 protrude toward the opening of the left middle bone 150 and the opening of the left middle bone 150 Engage with the edges 158, 159. As a result, a hollow portion (first isobaric space portion) 280 is formed between the right middle bone 140 and the left middle bone 150.
カーテンウォールユニット１００の外部側に位置する左中骨１５０の開口の縁１５８に、耐シリコン性エチレン・プロピレン・ジエンゴム（ＥＰＤＭ―Ｓ）から成るレインバリア１５３が設けられる。レインバリア１５３は、縁１５８と嵌合突起１４３との間に挟まれて両者に密着して止水し、中空部２８０に雨水が浸入することを防ぐ。カーテンウォールユニット１００の躯体側に位置する左中骨１５０の開口の縁１５９に、耐シリコン性エチレン・プロピレン・ジエンゴム（ＥＰＤＭ―Ｓ）から成るウインドバリア１５５が設けられる。ウインドバリア１５５は、縁１５９と嵌合突起１４３との間に挟まれて両者に密着し、中空部２８０の気密性を保持する。 A rain barrier 153 made of silicon-resistant ethylene / propylene / diene rubber (EPDM-S) is provided at the opening edge 158 of the left middle bone 150 located on the outer side of the curtain wall unit 100. The rain barrier 153 is sandwiched between the edge 158 and the fitting protrusion 143 so as to be in close contact with the both to stop water, and prevent rainwater from entering the hollow portion 280. A wind barrier 155 made of silicon-resistant ethylene / propylene / diene rubber (EPDM-S) is provided at the edge 159 of the opening of the left middle bone 150 located on the frame side of the curtain wall unit 100. The wind barrier 155 is sandwiched between the edge 159 and the fitting protrusion 143 and is in close contact with the both, and maintains the airtightness of the hollow portion 280.
前述のように、右中骨１４０及び左中骨１５０の下端と、スプライサー２７０の内底２７１との間に空間が形成されているため、嵌合凹溝１１７は中空部２８０と連続する空間を成す。 As described above, since a space is formed between the lower ends of the right middle bone 140 and the left middle bone 150 and the inner bottom 271 of the splicer 270, the fitting groove 117 has a space continuous with the hollow portion 280. Make it.
右下枠１８０は右中骨１４０の側面１４２にビス２６１を用いて固定され、左下枠１９０は左中骨１５０の側面１５２にビス２６２を用いて固定される。この固定状態をいわゆる中骨勝ちという。なお、同様にして、右下枠１８０が右縦枠１２０の側面１２１にビス止めされ、左下枠１９０が左縦枠１３０の側面１３１にビス止めされる。 The lower right frame 180 is fixed to the side surface 142 of the right middle bone 140 using screws 261, and the lower left frame 190 is fixed to the side surface 152 of the left middle bone 150 using screws 262. This fixed state is called so-called “winning the core”. Similarly, the lower right frame 180 is screwed to the side surface 121 of the right vertical frame 120, and the lower left frame 190 is screwed to the side surface 131 of the left vertical frame 130.
右中骨１４０の側面１４２と右下枠１８０との間、左中骨１５０の側面１５２と左下枠１９０との間、右縦枠１２０の側面１２１と右下枠１８０との間、及び左縦枠１３０の側面１３１と左下枠１９０との間に、エチレン・プロピレン・ジエンゴム（ＥＰＤＭ）から成るシーラー２７２が設けられる。シーラー２７２は、側面１４２と右下枠１８０とから所定の圧力を受けてこれらに密着し、側面１４２と右下枠１８０との間を止水する。左中骨１５０、右縦枠１２０、及び左縦枠１３０についても同様に止水される。 Between the side surface 142 of the right middle bone 140 and the lower right frame 180, between the side surface 152 of the left middle bone 150 and the lower left frame 190, between the side surface 121 of the right vertical frame 120 and the lower right frame 180, and left vertical A sealer 272 made of ethylene / propylene / diene rubber (EPDM) is provided between the side surface 131 of the frame 130 and the lower left frame 190. The sealer 272 receives a predetermined pressure from the side surface 142 and the lower right frame 180 and comes into close contact therewith, and stops water between the side surface 142 and the lower right frame 180. The left central bone 150, the right vertical frame 120, and the left vertical frame 130 are similarly stopped.
従来の中骨勝ちでない下枠勝ちの構成では、右中骨及び左中骨は１本の下枠の頂面にシーラーを介して固定されていた。この構成では、右中骨と左中骨との長さに誤差がある場合、右中骨と下枠との間の圧力と、左中骨と下枠との間の圧力とが均一にならず、いずれか一方の圧力が弱い方において水密性を保てず、雨水がカーテンウォールユニットを超えて躯体側に進入する可能性があった。しかしながら本実施形態では、中骨勝ちとすることにより、右下枠１８０と右中骨１４０は、左下枠１９０と左中骨１５０の間の圧力に関わらず、シーラー２７２を介して密着し、水密性を確実に保ち、雨水がカーテンウォールユニット１００を超えて躯体側に進入することを防止できる。同様にして、左下枠１９０と左中骨１５０は、右下枠１８０と右中骨１４０の間の圧力に関わらず、雨水が躯体側に進入することを防止できる。 In the conventional lower frame winning configuration that does not win the middle bone, the right and left middle bones are fixed to the top surface of one lower frame via a sealer. In this configuration, if there is an error in the length of the right and left medial bones, the pressure between the right medial bone and the lower frame and the pressure between the left medial bone and the lower frame are equalized. However, the water tightness could not be maintained in the case where either one of the pressures was weak, and there was a possibility that rainwater would enter the enclosure side beyond the curtain wall unit. However, in the present embodiment, by winning the middle bone, the right lower frame 180 and the right middle bone 140 are in close contact with each other through the sealer 272 regardless of the pressure between the left lower frame 190 and the left middle bone 150, and are watertight. Thus, it is possible to prevent the rainwater from entering the enclosure beyond the curtain wall unit 100. Similarly, the lower left frame 190 and the left middle bone 150 can prevent rainwater from entering the housing regardless of the pressure between the lower right frame 180 and the right middle bone 140.
クロロプレンゴムスポンジから成る２つの等圧区画材２９０が、嵌合凹溝１１７内に設けられる。２つの等圧区画材２９０の端部は、スプライサー２７０の長手方向の両端の各々とシーリング材２９１を介して密着する。等圧区画材２９０において、スプライサー２７０と密着しない他端は、シーリング材２９１を用いて止水される。等圧区画材２９０の頂面は、嵌合凹溝１１７内に進入している右下枠１８０及び左下枠１９０の底部の反転形状を有し、右下枠１８０及び左下枠１９０の底部と密着する。等圧区画材２９０の底面は、嵌合凹溝１１７の底と密着する。これにより、空間１５７は等圧区画材２９０によって幅方向に区切られる。 Two isobaric partition members 290 made of chloroprene rubber sponge are provided in the fitting groove 117. The ends of the two isobaric partition members 290 are in close contact with each of both ends in the longitudinal direction of the splicer 270 via the sealing material 291. In the isobaric partition material 290, the other end not in close contact with the splicer 270 is stopped using a sealing material 291. The top surface of the isobaric partition member 290 has an inverted shape of the bottoms of the lower right frame 180 and the lower left frame 190 entering the fitting groove 117, and is in close contact with the bottoms of the lower right frame 180 and the lower left frame 190. To do. The bottom surface of the isobaric partition material 290 is in close contact with the bottom of the fitting groove 117. Thereby, the space 157 is partitioned in the width direction by the isobaric partition material 290.
下部補強材２４０の外周には、下部補強材２４０の全長に渡って延びるＬ字型の４つの係合突起２４１が設けられ、右中骨１４０と左中骨１５０の内周には、右中骨１４０と左中骨１５０の一部又は全長に渡って延びるＬ字型の４つの係合突起１４４、１５４が設けられる。係合突起２４１は、右中骨１４０と左中骨１５０の内周に設けられた係合突起１４４、１５４と各々係合する。これにより、下部補強材２４０、右中骨１４０と左中骨１５０は、水平面内に対して互いに固定される。下部補強材２４０は、左中骨１５０の嵌合突起１４３にビス２６３を用いて固定される。以上の部材により、右中骨１４０と左中骨１５０とが互いに密着して固定され、カーテンウォールユニット１００の搬送及び取り付け時に加えられる外力や、建築物に取り付けられた後に受ける風圧等の外力によって、右中骨１４０と左中骨１５０とが離れてしまうことがない。 Four L-shaped engagement protrusions 241 extending over the entire length of the lower reinforcement member 240 are provided on the outer periphery of the lower reinforcement member 240, and the right middle bone 140 and the left middle bone 150 are provided on the inner periphery thereof with the right middle portion. Four L-shaped engaging protrusions 144 and 154 extending over a part or the entire length of the bone 140 and the left middle bone 150 are provided. The engagement protrusions 241 engage with the engagement protrusions 144 and 154 provided on the inner circumferences of the right middle bone 140 and the left middle bone 150, respectively. As a result, the lower reinforcing member 240, the right middle bone 140, and the left middle bone 150 are fixed to each other in the horizontal plane. The lower reinforcing member 240 is fixed to the fitting protrusion 143 of the left middle bone 150 using screws 263. By the above members, the right middle bone 140 and the left middle bone 150 are fixed in close contact with each other, and by external force applied when the curtain wall unit 100 is transported and attached, or by external force such as wind pressure received after being attached to the building. The right middle bone 140 and the left middle bone 150 are not separated from each other.
右中骨１４０と左中骨１５０の躯体側に取り付けられるビス２６３の躯体側から、内部塞ぎゴム２７３が取り付けられる。これにより、ビス２６３の周囲から中空部２８０に雨水や空気が入ることを防止できる。 An internal closing rubber 273 is attached from the housing side of the screw 263 attached to the housing side of the right middle bone 140 and the left middle bone 150. Thereby, rainwater and air can be prevented from entering the hollow portion 280 from the periphery of the screw 263.
図５は上部補強材２３０の断面を示す。上部補強材２３０は、下部補強材２４０と同様の形状を有し、同様の構成によって右中骨１４０と左中骨１５０に接続される。これにより、右中骨１４０と左中骨１５０とが互いに密着して固定され、カーテンウォールユニット１００の搬送及び取り付け時に加えられる外力や、建築物に取り付けられた後に受ける風圧等の外力によって、右中骨１４０と左中骨１５０とが離れてしまうことがない。 FIG. 5 shows a cross section of the upper reinforcement 230. The upper reinforcing member 230 has the same shape as the lower reinforcing member 240 and is connected to the right middle bone 140 and the left middle bone 150 by the same configuration. As a result, the right middle bone 140 and the left middle bone 150 are fixed in close contact with each other. The external force applied when the curtain wall unit 100 is transported and attached, and the external force such as wind pressure received after being attached to the building The middle bone 140 and the left middle bone 150 are not separated.
次に、図６を用いて、外気の流れについて説明する。なお、説明の容易ため、図６においてスプライサー２７０及び等圧区画材２９０は省略される。重力方向下側に位置するカーテンウォールユニット１００ａの通気口１１９から、重力方向上側に位置するカーテンウォールユニット１００ｂの嵌合凹溝１１７に外気が流入する。ここで、前述のように、嵌合凹溝１１７は通気口１１９から右中骨１４０及び左中骨１５０の下端の下方に延びている。そのため、外気は嵌合凹溝１１７を経て中空部２８０まで流出入する。他方、前述のように、重力方向下側に位置するカーテンウォールユニット１００ａの上枠１１０と、右中骨１４０及び左中骨１５０の下端との間には隙間がある。この隙間を通って、外気が中空部２８０まで流出入する。これにより、嵌合凹溝１１７及び中空部２８０が外気圧と同じ圧力に維持されて、圧力差によって雨水が進入することがない。 Next, the flow of outside air will be described with reference to FIG. For ease of explanation, the splicer 270 and the isobaric partition material 290 are omitted in FIG. Outside air flows from the vent 119 of the curtain wall unit 100a located on the lower side in the gravity direction into the fitting groove 117 of the curtain wall unit 100b located on the upper side in the gravity direction. Here, as described above, the fitting groove 117 extends from the vent hole 119 below the lower ends of the right middle bone 140 and the left middle bone 150. Therefore, the outside air flows into and out of the hollow portion 280 through the fitting concave groove 117. On the other hand, as described above, there is a gap between the upper frame 110 of the curtain wall unit 100a located on the lower side in the gravity direction and the lower ends of the right middle bone 140 and the left middle bone 150. Through this gap, outside air flows into and out of the hollow portion 280. Thereby, the fitting ditch | groove 117 and the hollow part 280 are maintained at the same pressure as external pressure, and rainwater does not approach by a pressure difference.
従来の下枠勝ちの構成では、右中骨及び左中骨は１本の下枠の頂面にシーラーを介して固定されていたため、右中骨及び左中骨の内部は下枠の頂面によって外気と遮断されて、外気と等圧ではなかった。そのため、右中骨及び左中骨の内部と外気との圧力差によって内部に雨水が浸入する可能性があり、これを防ぐために、右中骨と左中骨とを接続するビス周りをシールする必要があった。しかしながら本実施形態では、下枠に対して中骨勝ちとすることにより中空部２８０が外気と等圧になったため、雨水が中空部２８０及び躯体側に進入することが少ない。そのため、右中骨と左中骨とを接続するビス、例えばビス２６３周りをシールする必要がなくなり、ビス周りのシールよりも簡易なレインバリア１５３による止水で足りることとなった。レインバリア１５３による止水を用いると、嵌合突起１４３を左中骨１５０に差し込むだけで止水処理が完了するため、カーテンウォールユニット１００の組立を従来よりも簡易にできる。 In the conventional lower frame winning configuration, the right and left middle bones are fixed to the top surface of one lower frame via a sealer, so the inside of the right and left middle bones is the top surface of the lower frame. It was cut off from the outside air by the pressure and was not equal to the outside air. Therefore, there is a possibility that rainwater may enter due to the pressure difference between the inside of the right and left middle bones and the outside air, and in order to prevent this, seal around the screw connecting the right and left middle bones There was a need. However, in the present embodiment, since the hollow portion 280 becomes equal in pressure to the outside air by winning the middle frame with respect to the lower frame, rainwater hardly enters the hollow portion 280 and the housing side. Therefore, there is no need to seal around the screw that connects the right and left ribs, for example, the screw 263, and water stop by the rain barrier 153 that is simpler than the seal around the screw is sufficient. When the water stop by the rain barrier 153 is used, the water stop process is completed simply by inserting the fitting protrusion 143 into the left middle bone 150. Therefore, the assembly of the curtain wall unit 100 can be simplified as compared with the conventional case.
本実施形態によれば、等圧区画を有しながら、カーテンウォールと躯体との間を止水可能であるカーテンウォールユニットを得る。 According to the present embodiment, a curtain wall unit is obtained that can stop water between the curtain wall and the housing while having an equal pressure section.
