Description

本開示は、方立のシール構造および方立のシール方法に関する。 This disclosure relates to a mullion sealing structure and a mullion sealing method.

商業施設やオフィスビル等の建築物の外部ファサードに複数の窓サッシを並べて方立で連結した連窓が採用されている。例えば、特許文献１には、外部用ファサードに用いるカーテンウォールが開示されている。特許文献１に記載のカーテンウォールは、ガラスを保持するための開口溝を方立内に設け、方立内部には外気導入する機構を備えている。 Commercial facilities, office buildings, and other buildings use continuous windows in which multiple window sashes are lined up and connected by mullions on their exterior facades. For example, Patent Document 1 discloses a curtain wall for use in exterior facades. The curtain wall described in Patent Document 1 has an opening groove in the mullion to hold the glass, and is equipped with a mechanism for introducing outside air into the mullion.

特開２０２１－１５２２４６号公報JP 2021-152246 A

近年、建築物の意匠性を高めるため、外部ファサードを構成する連窓も意匠性の高い製品が求められている。例えば、方立の幅方向の寸法を極小化すると、方立が目立たず広いガラス面を強調した外観が得られる。しかし、特許文献１に記載のように、外気導入経路を確保しつつ、外部ファサード用の方立の幅方向の寸法の極小化を図る場合、外気導入経路のスペースが減少する。そのため、方立内の限られたスペースで気密性を保つことは構造上、および施工上困難であった。 In recent years, in order to improve the design of buildings, there has been a demand for highly aesthetically pleasing products for the interlocking windows that make up the exterior façade. For example, minimizing the width dimension of the mullions makes the mullions less noticeable and creates an appearance that emphasizes the wide glass surface. However, as described in Patent Document 1, when minimizing the width dimension of the mullions for the exterior façade while ensuring an outside air intake path, the space for the outside air intake path is reduced. For this reason, it has been structurally and constructionally difficult to maintain airtightness in the limited space within the mullions.

本開示は、上記事情に鑑みてなされたものであり、外観意匠性と気密性を両立させた外部ファサード用の方立を実現できる方立のシール構造および方立のシール方法を提供することを目的とする。 This disclosure has been made in consideration of the above circumstances, and aims to provide a mullion sealing structure and a mullion sealing method that can realize a mullion for an external facade that combines aesthetic appearance and airtightness.

本開示の一態様に係る方立のシール構造は、方立の上下方向の端部開口から湿式シール材を充填する空間である湿式シール充填部が前記方立に形成され、前記湿式シール充填部に充填された前記湿式シール材によって、前記方立の上下方向の端部の少なくとも一部を封止する。 In one aspect of the sealing structure of the upright of the present disclosure, a wet seal filling section, which is a space into which a wet sealant is filled from the openings at the top and bottom ends of the upright, is formed in the upright, and at least a portion of the top and bottom ends of the upright are sealed by the wet sealant filled in the wet seal filling section.

以下、図面を参照し、方立２のシール構造１および方立２のシール方法の一実施形態を説明する。方立２のシール構造１および方立２のシール方法は、例えば、図１に示すような連窓ユニット１００に採用できる。連窓ユニット１００は、複数の板材１１が支持体８に支持されている。連窓ユニット１００は、建物の開口に取り付けられる。以下の説明では、板材１１の厚さ方向を見込方向Ｄと称する。見込方向Ｄと直交する水平方向を幅方向Ｗと称する。見込方向Ｄおよび幅方向Ｗと直交する方向を上下方向Ｈと称する。 Below, one embodiment of the sealing structure 1 for the mullion 2 and the sealing method for the mullion 2 will be described with reference to the drawings. The sealing structure 1 for the mullion 2 and the sealing method for the mullion 2 can be adopted, for example, in a continuous window unit 100 as shown in FIG. 1. The continuous window unit 100 has a plurality of plate materials 11 supported by a support 8. The continuous window unit 100 is attached to an opening in a building. In the following description, the thickness direction of the plate materials 11 is referred to as the prospective direction D. The horizontal direction perpendicular to the prospective direction D is referred to as the width direction W. The direction perpendicular to the prospective direction D and the width direction W is referred to as the up-down direction H.

支持体８は、上枠８１と、下枠８２と、一対の縦枠８９と、一以上の方立２と、一以上の無目８３とを備える。上枠８１と、下枠８２と、一対の縦枠８９とが矩形に組み立てられて外枠８０を構成している。外枠８０は、建物の開口に固定される。方立２および無目８３は、外枠８０内で格子状に配置されている。方立２は、上下方向Ｈに沿って配置され上枠８１および下枠８２に連結されている。無目８３は、一対の縦枠８９間に上枠８１および下枠８２と平行に配置されている。板材１１は例えば、ガラスである。板材１１は、単層ガラス、複層ガラスのいずれでもよい。板材１１は、外枠８０の内側に幅方向Ｗおよび上下方向Ｈに並べられている。板材１１は、外枠８０と方立２と無目８３とで形成された各矩形空間内に配置されて支持される。図１では、連窓ユニット１００の一例として、６枚の板材１１が並ぶ例を図示しているが、連窓ユニット１００の板材１１の数は図示例に限定されない。連窓ユニット１００は建具の一例である。 The support 8 includes an upper frame 81, a lower frame 82, a pair of vertical frames 89, one or more uprights 2, and one or more lattice marks 83. The upper frame 81, the lower frame 82, and the pair of vertical frames 89 are assembled into a rectangle to form the outer frame 80. The outer frame 80 is fixed to an opening in the building. The uprights 2 and lattice marks 83 are arranged in a lattice pattern within the outer frame 80. The uprights 2 are arranged along the vertical direction H and are connected to the upper frame 81 and the lower frame 82. The lattice marks 83 are arranged parallel to the upper frame 81 and the lower frame 82 between the pair of vertical frames 89. The plate material 11 is, for example, glass. The plate material 11 may be either single-layer glass or double-layer glass. The plate material 11 is arranged inside the outer frame 80 in the width direction W and the vertical direction H. The plate material 11 is arranged and supported within each rectangular space formed by the outer frame 80, the uprights 2, and the lattice marks 83. In FIG. 1, an example of a multi-window unit 100 is shown in which six panels 11 are arranged, but the number of panels 11 in the multi-window unit 100 is not limited to the illustrated example. The multi-window unit 100 is an example of a fixture.

方立２は、直方体形状の長尺部材である。図２に示すように、方立２は、内端壁６３と、外端壁６４と、一対の側壁６１，６２とを備える。内端壁６３は、見込方向Ｄの室内Ｉ側を向く。外端壁６４は、見込方向Ｄの室外Ｏ側を向く。一対の側壁６１，６２は、幅方向Ｗを向く。図示例では、方立２は、幅方向Ｗの寸法が短く、見込方向Ｄの寸法が長い。方立２は、幅方向Ｗの寸法が極めて小さく、見込方向Ｄの寸法が長い為、連窓ユニット１００の外観上、方立２が細長い特徴的な意匠を有する。 The mullion 2 is a long member having a rectangular parallelepiped shape. As shown in FIG. 2, the mullion 2 has an inner end wall 63, an outer end wall 64, and a pair of side walls 61, 62. The inner end wall 63 faces the indoor I side in the projection direction D. The outer end wall 64 faces the outdoor O side in the projection direction D. The pair of side walls 61, 62 face in the width direction W. In the illustrated example, the mullion 2 has a short dimension in the width direction W and a long dimension in the projection direction D. Since the mullion 2 has an extremely small dimension in the width direction W and a long dimension in the projection direction D, the mullion 2 has a distinctive elongated design in terms of the appearance of the continuous window unit 100.

図２および図３に示すように、方立２は、第一部品２１と第二部品２２とが連結されている。第一部品２１および第二部品２２は、上下方向Ｈに長い型材である。第一部品２１の側壁６１の内面２１１と第二部品２２の側壁６２の内面２２１とが離間した位置で対向配置されている。第一部品２１と第二部品２２とは、外側連結部２７１および内側連結部２７２が係合されることによって連結されている。内側連結部２７２は、第一部品２１の内係止片２４１と、第二部品２２の内係止片２４２とが係止されている。 As shown in Figures 2 and 3, the mullion 2 is connected to a first part 21 and a second part 22. The first part 21 and the second part 22 are elongated moldings in the vertical direction H. The inner surface 211 of the side wall 61 of the first part 21 and the inner surface 221 of the side wall 62 of the second part 22 are arranged facing each other at a distance. The first part 21 and the second part 22 are connected by engaging an outer connecting part 271 and an inner connecting part 272. The inner connecting part 272 is engaged with an inner locking piece 241 of the first part 21 and an inner locking piece 242 of the second part 22.

図２に示すように、第一部品２１の外端壁６４の内側に内面２２１から突出する外係止片２４３が形成されている。第二部品２２の室外Ｏ側の端部には、内面２２１から突出する外係止片２４４が形成されている。第二部品２２の外係止片２４４は、外端壁６４と略平行に延びる部分と見込方向Ｄに延びる部分とを有する略Ｌ字形状を有する。外側連結部２７１は、第一部品２１の外係止片２４３と外端壁６４との間に、第二部品２２の外係止片２４４が挿入されて係止される。第一部品２１の外係止片２４３には、第二部品２２の外係止片２４４との当接部位に係止凸部２４６が形成されている。係止凸部２４６は、室外Ｏ側に僅かに突出している。係止凸部２４６によって、外係止片２４３，２４４同士の係止状態が補強される。例えば、方立２に強風等の外力が掛かった時にも外側連結部２７１の係止状態が安定的に保持できる。 As shown in FIG. 2, an outer locking piece 243 protruding from the inner surface 221 is formed on the inside of the outer end wall 64 of the first component 21. An outer locking piece 244 protruding from the inner surface 221 is formed at the end of the second component 22 on the outside O side. The outer locking piece 244 of the second component 22 has a substantially L-shaped shape with a portion extending substantially parallel to the outer end wall 64 and a portion extending in the expected direction D. The outer connecting portion 271 is engaged by inserting the outer locking piece 244 of the second component 22 between the outer locking piece 243 of the first component 21 and the outer end wall 64. A locking protrusion 246 is formed on the outer locking piece 243 of the first component 21 at the abutment portion with the outer locking piece 244 of the second component 22. The locking protrusion 246 protrudes slightly toward the outside O side. The locking protrusion 246 reinforces the locking state between the outer locking pieces 243 and 244. For example, the outer connecting part 271 can be stably maintained in its locked state even when an external force such as a strong wind is applied to the mullion 2.

外係止片２４４には、シール部材４９の一端部を収容する凹部２４５が形成されている。第二部品２２の外端２８と外端壁６４の端部とが当接している。外端２８と凹部２４５と外係止片２４４の間にシール部材４９が配置される。外側連結部２７１は、各外係止片２４３，２４４が見込方向Ｄに重なり、かつ幅方向Ｗに係止されているため、方立２に外力が掛かった場合も連結状態を安定的に保持できる。外側連結部２７１は、外係止片２４３，２４４と外端壁６４とで囲まれた空間にシール部材４９が設けられているため、封止状態が安定的に保持される。 The outer locking piece 244 has a recess 245 formed therein to accommodate one end of the seal member 49. The outer end 28 of the second component 22 abuts against the end of the outer end wall 64. The seal member 49 is disposed between the outer end 28, the recess 245, and the outer locking piece 244. The outer connecting portion 271 has the outer locking pieces 243, 244 overlapping in the projection direction D and locked in the width direction W, so that the connected state can be stably maintained even when an external force is applied to the upright 2. The outer connecting portion 271 has the seal member 49 provided in the space surrounded by the outer locking pieces 243, 244 and the outer end wall 64, so that the sealed state is stably maintained.

第一部品２１には、内面２１１から第二部品２２に向かって突出する２つの凸部２５，２６を備える。２つの凸部２５，２６は、見込方向Ｄに離れた位置で上下方向Ｈに略平行に延びている。図示例では、各凸部２５，２６は水平断面形状が略Ｌ字形状を有する。各凸部２５，２６は、第一部２５１，２６１および第二部２５２，２６２を有する。各凸部２５，２６の第一部２５１，２６１は、内面２１１から幅方向Ｗに突出している。第二部２５２，２６２は、第一部２５１，２６１の突出端から見込方向Ｄに延びるように曲折している。第二部２５２，２６２は、第二部品２２の内面２２１と対向配置される。各第二部２５２，２６２は同じ向きに折れ曲がっている。 The first part 21 has two protrusions 25, 26 that protrude from the inner surface 211 toward the second part 22. The two protrusions 25, 26 extend approximately parallel to the up-down direction H at positions separated in the projection direction D. In the illustrated example, each of the protrusions 25, 26 has a horizontal cross-sectional shape that is approximately L-shaped. Each of the protrusions 25, 26 has a first portion 251, 261 and a second portion 252, 262. The first portion 251, 261 of each of the protrusions 25, 26 protrudes from the inner surface 211 in the width direction W. The second portions 252, 262 are bent so as to extend from the protruding ends of the first portions 251, 261 in the projection direction D. The second portions 252, 262 are disposed opposite the inner surface 221 of the second part 22. Each of the second portions 252, 262 is bent in the same direction.

各凸部２５，２６のうち、室内Ｉ側に位置する内側凸部２６と第二部品２２の内面２２１との間には、シール部材４８が設けられている。シール部材４８は、例えば、長尺な平板状の乾式シール部材である。室外Ｏ側に位置する外側凸部２５と第二部品２２の内面２２１との間は隙間が形成されている。 A sealing member 48 is provided between the inner protrusion 26 located on the indoor I side of each of the protrusions 25, 26 and the inner surface 221 of the second part 22. The sealing member 48 is, for example, a long, flat, dry sealing member. A gap is formed between the outer protrusion 25 located on the outdoor O side and the inner surface 221 of the second part 22.

方立２の内部には上下方向Ｈに延びる中空部が形成されている。図示例では、方立２の中空部は、見込方向Ｄに３つの空間に仕切られている。方立２の３つの空間を、見込方向Ｄの外側Ｏから順に第一中空部Ｓ１、第二中空部Ｓ２、および第三中空部Ｓ３と称する。第一中空部Ｓ１は、第一部品２１および第二部品２２の各内面２１１，２２１と、外側凸部２５と、外側連結部２７１とで囲まれた空間である。第二中空部Ｓ２は、外側凸部２５と、内側凸部２６と、第一部品２１および第二部品２２の各内面２１１，２２１とで囲まれた空間である。第三中空部Ｓ３は、第一部品２１および第二部品２２の各内面２１１，２２１と、内側凸部２６と、内側連結部２７２とで囲まれた空間である。内側凸部２６と第二部品２２の内面２２１との間に設けられたシール部材４９によって、第三中空部Ｓ３は、第一中空部Ｓ１および第二中空部Ｓ２に対して封止されている。 A hollow portion extending in the vertical direction H is formed inside the upright 2. In the illustrated example, the hollow portion of the upright 2 is divided into three spaces in the projection direction D. The three spaces of the upright 2 are called the first hollow portion S1, the second hollow portion S2, and the third hollow portion S3, in order from the outside O in the projection direction D. The first hollow portion S1 is a space surrounded by the inner surfaces 211 and 221 of the first part 21 and the second part 22, the outer convex portion 25, and the outer connecting portion 271. The second hollow portion S2 is a space surrounded by the outer convex portion 25, the inner convex portion 26, and the inner surfaces 211 and 221 of the first part 21 and the second part 22. The third hollow portion S3 is a space surrounded by the inner surfaces 211 and 221 of the first part 21 and the second part 22, the inner convex portion 26, and the inner connecting portion 272. The third hollow portion S3 is sealed from the first hollow portion S1 and the second hollow portion S2 by a seal member 49 provided between the inner convex portion 26 and the inner surface 221 of the second component 22.

The blind vent 832 penetrates the bottom of the blind 83 in the vertical direction H. The blind vent 832 functions as an outside air inlet that can introduce outside air into the hollow part from outside the blind 83. The blind vent 832 opens near the end of the lower part on the plate material 11 side in the prospective direction D. The blind vent 832 is formed in a position that is not noticeable from the outside. Although not shown in the figure, vents are also formed in the panel holding part 84 and the side walls 61 and 62 of the mullion 2. An outside air introduction path is formed from the blind vent 832 to the first hollow part S1 of the mullion 2, passing through the hollow part of the blind 83, the horizontal opening at the end of the blind 83, the panel holding part 84, and the side walls 61 and 62 of the mullion 2.

乾式シール部材４１および乾式端部シール部材４２は、例えば、スポンジ状の微細多孔質部材である。湿式シール材５は、充填時は流体であり、充填後、経時硬化する。 The dry sealing member 41 and the dry end sealing member 42 are, for example, sponge-like microporous members. The wet sealing material 5 is a fluid when filled, and hardens over time after filling.

次に、方立２のシール構造１について説明する。湿式シール充填部３に湿式シール材５が充填される。図３に示すように、方立２の下端開口２９の室外Ｏ側の領域は湿式シール材５で封止される。方立２の室外Ｏ側の中空部Ｓ１は、密封性の安定的な保持が望まれる。方立２の下端開口２９の室外Ｏ側の領域が湿式シール材５で封止されることによって、第一中空部Ｓ1が安定的に封止できる。 Next, the sealing structure 1 of the upright 2 will be described. The wet seal filling portion 3 is filled with wet sealant 5. As shown in FIG. 3, the area of the bottom opening 29 of the upright 2 facing the outside O is sealed with wet sealant 5. It is desirable to maintain stable sealing of the hollow portion S1 on the outside O side of the upright 2. By sealing the area of the bottom opening 29 of the upright 2 facing the outside O with wet sealant 5, the first hollow portion S1 can be stably sealed.

図６に示すように、湿式シール充填部３の上方に乾式シール部材４２が設けられているため、上下方向Ｈに湿式シール材５と乾式シール部材４２とが並んで配置される。この構成によって、方立２の室外Ｏ側の第一中空部Ｓ１がより確実に封止できる。 As shown in FIG. 6, a dry seal member 42 is provided above the wet seal filling section 3, so that the wet seal material 5 and the dry seal member 42 are arranged side by side in the vertical direction H. This configuration allows the first hollow section S1 on the outside O side of the upright 2 to be sealed more reliably.

方立２の下端開口２９の外側凸部２５よりも室内Ｉ側の領域は乾式端部シール部材４１で封止される。室内Ｉ側の中空部Ｓ２、Ｓ３は容易に取り付け可能な乾式端部シール部材４１で封止し、高い密封性が望まれる室外Ｏ側の下端開口２９は、湿式シール材５で封止する。湿式シール材５によって、室外Ｏ側の下端開口２９は封止性能が安定する。この構成によって、施工が容易でありながら、高い気密性能を保持できるという効果を奏する。 The area on the indoor I side of the outer protrusion 25 of the lower end opening 29 of the upright 2 is sealed with a dry end seal member 41. The hollows S2 and S3 on the indoor I side are sealed with an easily attachable dry end seal member 41, and the lower end opening 29 on the outdoor O side, where high sealing performance is desired, is sealed with a wet seal material 5. The wet seal material 5 stabilizes the sealing performance of the lower end opening 29 on the outdoor O side. This configuration has the effect of maintaining high airtightness performance while being easy to install.

連窓ユニット１００を建物の外壁の開口に設ける場合、連窓ユニット１００の室外側は外部環境に晒される。連窓ユニット１００は、方立２の内部に中空部Ｓ１，Ｓ２，Ｓ３を設けることによって、外気温を室内側に伝え難くし、断熱性能が向上する。方立２の内部に中空部Ｓ１，Ｓ２，Ｓ３を設けることによって、防音性能を高めることができる。しかし、方立２の内部に中空部を設けると、例えば、連窓ユニット１００が雨に晒された時、板材１１よりも室外Ｏ側に位置する方立２の内部に雨水が浸入する可能性がある。雨水が浸入することを防止する観点、および断熱性能や防音性能を高める観点から、方立２の中空部Ｓ１，Ｓ２，Ｓ３の水密性は重要である。特に板材１１よりも室外側に位置する第一中空部Ｓ１の水密性が重要である。 When the multi-window unit 100 is installed in an opening in the exterior wall of a building, the outdoor side of the multi-window unit 100 is exposed to the external environment. By providing hollow sections S1, S2, and S3 inside the mullion 2, the multi-window unit 100 makes it difficult for outside air temperature to be transmitted to the indoor side, improving the insulation performance. By providing hollow sections S1, S2, and S3 inside the mullion 2, the soundproofing performance can be improved. However, if a hollow section is provided inside the mullion 2, for example, when the multi-window unit 100 is exposed to rain, rainwater may infiltrate into the inside of the mullion 2 located on the outside O side of the plate material 11. From the viewpoint of preventing rainwater from infiltrating and from the viewpoint of improving the insulation performance and soundproofing performance, the watertightness of the hollow sections S1, S2, and S3 of the mullion 2 is important. In particular, the watertightness of the first hollow section S1 located on the outdoor side of the plate material 11 is important.

上記観点に基づき、方立２の下端部には、乾式端部シール部材４１および乾式シール部材４２を設けている。乾式シール部材４１，４２は、両面テープや接着剤等で、第一部品２１または第二部品２２に容易に取り付けられる。例えば、乾式端部シール部材４１および乾式シール部材４１は、工場や施工現場における組み立て工程時に容易に取り付けられる利点がある。しかし、連窓ユニット１００が建物の外壁の開口に取り付けられる場合、風等の外力に起因して板材１１や無目８３や方立２に一時的に揺れや撓みが生じ得る。方立２の揺れや撓みに起因して、乾式端部シール部材４１および乾式シール部材４１と方立２の内面２１１，２２１との間に小さな隙間が一時的に生じ得る。そこで、方立２の下端部の見込方向Ｄの室外Ｏ側部分に湿式シール充填部３を設け、湿式シール材５を充填し、より確実に中空部Ｓ１，Ｓ２，Ｓ３を封止できる構造を実現した。方立２の下端部のうち、少なくとも室外Ｏ側の領域に湿式シール材５が設けられることによって、方立２の中空部Ｓ１の封止状態を安定させることができる。 Based on the above viewpoint, the dry end seal member 41 and the dry seal member 42 are provided at the lower end of the mullion 2. The dry seal members 41 and 42 can be easily attached to the first part 21 or the second part 22 with double-sided tape, adhesive, or the like. For example, the dry end seal member 41 and the dry seal member 41 have the advantage of being easily attached during the assembly process at a factory or construction site. However, when the continuous window unit 100 is attached to an opening in the exterior wall of a building, the plate material 11, the lattice 83, and the mullion 2 may temporarily sway or bend due to external forces such as wind. Due to the swaying or bending of the mullion 2, a small gap may temporarily occur between the dry end seal member 41 and the dry seal member 41 and the inner surface 211 and 221 of the mullion 2. Therefore, a wet seal filling portion 3 is provided at the outside O side portion of the lower end of the mullion 2 in the prospective direction D, and a wet seal material 5 is filled in, thereby realizing a structure that can more reliably seal the hollow portions S1, S2, and S3. By providing a wet sealant 5 at least in the area of the lower end of the upright 2 facing the outside O, the sealing state of the hollow portion S1 of the upright 2 can be stabilized.

（方立のシール方法）
次に、方立のシール方法を説明する。第一部品２１と第二部品２２とを連結する前に、乾式端部シール部材４１および乾式シール部材４２を取り付ける。第一部品２１の下端よりも上方であって、外側凸部２５の下方に貫通孔７を形成する。貫通孔７は、第一部品２１の製造段階で予め加工していてもよい。第一部品２１と第二部品２２とを連結して方立２を組み立てる。施工現場で建物の開口に外枠８０を取り付け、支持体８および板材１１を組み立てることによって、連窓ユニット１００を開口に取り付ける。 (How to seal the mullion)
Next, a method for sealing the mullions will be described. Before connecting the first part 21 and the second part 22, the dry end seal member 41 and the dry seal member 42 are attached. A through hole 7 is formed above the lower end of the first part 21 and below the outer protrusion 25. The through hole 7 may be pre-machined during the manufacturing stage of the first part 21. The first part 21 and the second part 22 are connected to assemble the mullions 2. At the construction site, an outer frame 80 is attached to the opening of the building, and the support body 8 and the plate material 11 are assembled, thereby attaching the multi-window unit 100 to the opening.

図７は、方立のシール方法を模式的に示す縦断面図である。図１に示すＡ７－Ａ７線から見た図である。建物の開口に連窓ユニット１００が取り付けられると、図４に示す方立２の下端開口２９のうち、室外Ｏ側の端部は下方に露出する。湿式シール充填部３の下部が露出する。作業者は、充填具２００を用いて湿式シール材５を湿式シール充填部３に充填する。例えば、充填具２００としてへらを用い、へらに湿式シール材５を載せて下端開口２９に近付けて順次充填する。例えば、充填具２００としてチューブ等を用い、チューブの先端を下端開口２９に挿入して湿式シール材５を充填する。 Figure 7 is a vertical cross-sectional view showing a schematic diagram of a method for sealing a mullion. It is a view taken from the A7-A7 line shown in Figure 1. When the multi-window unit 100 is attached to an opening in a building, the end of the lower end opening 29 of the mullion 2 shown in Figure 4 facing the outside O is exposed downward. The lower part of the wet seal filling section 3 is exposed. The worker fills the wet sealant 5 into the wet seal filling section 3 using a filling tool 200. For example, a spatula is used as the filling tool 200, and the wet sealant 5 is placed on the spatula and brought close to the lower end opening 29 to fill it in succession. For example, a tube or the like is used as the filling tool 200, and the tip of the tube is inserted into the lower end opening 29 to fill the wet sealant 5.

湿式シール充填部３は方立２の下端開口２９に連続して設けられているため、湿式シール材５は方立２の下方から充填する必要がある。方立２の下端開口２９の下方から湿式シール材５を充填する場合、作業者は充填状況を目視で確認し難い。これに対し、方立２の側壁６１には、湿式シール充填部３の上端部３１に貫通する貫通孔７が形成されている。下端開口２９から充填された湿式シール材５が湿式シール充填部３の上端部３１に達すると、湿式シール材５が貫通孔７から方立２の外部に溢れ出る。湿式シール充填部３が湿式シール材５で満たされると湿式シール材５の充填が完了する。貫通孔７は、方立２の側壁６１の目視可能な位置に開口しているため、貫通孔７から湿式シール材５が溢れ出たことが容易に確認できる。貫通孔７から湿式シール材５が溢れ出ると、作業者は湿式シール充填部３が湿式シール材５で満たされたことが認識できる。湿式シール材５が貫通孔７から溢れ出た時点で、作業者は湿式シール材５の充填を停止する。必要に応じて、貫通孔７から溢れ出た湿式シール材５を拭き取る。この構成によって、作業者は湿式シール材５の充填作業を効率的に行える。 Because the wet seal filling section 3 is provided in continuity with the lower end opening 29 of the mullion 2, the wet sealant 5 must be filled from below the mullion 2. When the wet sealant 5 is filled from below the lower end opening 29 of the mullion 2, it is difficult for the worker to visually check the filling status. In response to this, a through hole 7 is formed in the side wall 61 of the mullion 2, penetrating to the upper end 31 of the wet seal filling section 3. When the wet sealant 5 filled from the lower end opening 29 reaches the upper end 31 of the wet seal filling section 3, the wet sealant 5 overflows from the through hole 7 to the outside of the mullion 2. When the wet seal filling section 3 is filled with the wet sealant 5, the filling of the wet sealant 5 is completed. Because the through hole 7 is opened at a visible position on the side wall 61 of the mullion 2, it is easy to check that the wet sealant 5 has overflowed from the through hole 7. When the wet sealant 5 overflows from the through-hole 7, the worker can recognize that the wet seal filling section 3 is filled with the wet sealant 5. When the wet sealant 5 overflows from the through-hole 7, the worker stops filling the wet sealant 5. If necessary, the wet sealant 5 that overflowed from the through-hole 7 is wiped off. This configuration allows the worker to efficiently fill the wet sealant 5.

図示例では、貫通孔７に加え、湿式シール充填部３の上方に乾式シール部材４２が設けられている。方立２の側壁６１の貫通孔７と、湿式シール充填部３の上方に設けられた乾式シール部材４２とを両方備えると、湿式シール材５の充填作業がより効率的に行える。湿式シール材５の充填時、乾式シール部材４２の下端面４２１に到達するまで湿式シール材５を充填すると、湿式シール材５が下端面４２１に堰き止められる。湿式シール材５が下端面４２１に堰き止められることによって、湿式シール材５の過度な充填が抑えられる。加えて、下端面４２１に堰き止められた湿式シール材５が横方向に流れ、貫通孔７から方立２の外部に溢れ出る。この結果、湿式シール材５の充填作業が円滑に行える。 In the illustrated example, in addition to the through hole 7, a dry seal member 42 is provided above the wet seal filling section 3. By providing both the through hole 7 in the side wall 61 of the upright 2 and the dry seal member 42 provided above the wet seal filling section 3, the wet seal material 5 can be filled more efficiently. When the wet seal material 5 is filled, if the wet seal material 5 is filled until it reaches the lower end surface 421 of the dry seal member 42, the wet seal material 5 is blocked by the lower end surface 421. By blocking the wet seal material 5 at the lower end surface 421, excessive filling of the wet seal material 5 is suppressed. In addition, the wet seal material 5 blocked at the lower end surface 421 flows laterally and overflows from the through hole 7 to the outside of the upright 2. As a result, the wet seal material 5 can be filled smoothly.

図５および図７に示すように、下枠８２の下端部には水切部８２１が設けられている。水切部８２１は、方立２の下端２３の下方を除く位置に設けられている。図５に示すように、方立２の幅方向Ｗの両側に配置される下枠８２の水切部８２１は、方立２の下方において幅方向Ｗに離間している。図４および図５に示すように、水切部８２１間の隙間Ｘから湿式シール材５を充填できる。水切部８２１同士が幅方向Ｗに離間配置されることによって、湿式シール材５の充填具の通過部が形成される。湿式シール材５の充填具の方立２の下端開口２９へのアクセスが妨げられず、湿式シール材５の充填作業が容易に行える。施工後、幅方向Ｗに隣り合う水切部８２１間の隙間に別の水切部材を取り付けて隙間Ｘを塞いでもよい。 5 and 7, a drainage portion 821 is provided at the lower end of the lower frame 82. The drainage portion 821 is provided at a position other than below the lower end 23 of the upright 2. As shown in FIG. 5, the drainage portions 821 of the lower frame 82 arranged on both sides of the width direction W of the upright 2 are spaced apart in the width direction W below the upright 2. As shown in FIG. 4 and FIG. 5, the wet sealant 5 can be filled through the gap X between the drainage portions 821. By arranging the drainage portions 821 apart from each other in the width direction W, a passage portion for the filler of the wet sealant 5 is formed. The access of the filler of the wet sealant 5 to the lower end opening 29 of the upright 2 is not hindered, and the filling work of the wet sealant 5 can be easily performed. After construction, another drainage member may be attached to the gap between the drainage portions 821 adjacent in the width direction W to close the gap X.

図７に示すように、下枠８２の室外Ｏ側の上部にはカバー部材８５が取り付けられる。図７では、説明のため、カバー部材８５を点線で示している。カバー部材８５と下枠８２との間に中空部Ｓ８２１が形成される。貫通孔７は、下枠８２の上方、かつカバー部材８５の下方に設けられている。湿式シール材５の充填後、カバー部材８５が取り付けられると、貫通孔７は、カバー部材８５で隠される。カバー部材８５と、板材１１と下枠８２との間に中空部Ｓ８２２が形成される。 As shown in FIG. 7, a cover member 85 is attached to the upper part of the lower frame 82 on the outside O side. In FIG. 7, the cover member 85 is shown with a dotted line for the sake of explanation. A hollow portion S821 is formed between the cover member 85 and the lower frame 82. The through hole 7 is provided above the lower frame 82 and below the cover member 85. When the cover member 85 is attached after the wet sealant 5 is filled, the through hole 7 is hidden by the cover member 85. A hollow portion S822 is formed between the cover member 85, the plate material 11, and the lower frame 82.

上記方立のシール構造１によれば、方立２の下端部に湿式シール充填部３を備えるため、方立２下端開口２９から湿式シール材５を充填できる。見込方向Ｄにおける方立２の下端部の少なくとも一部に湿式シール材５を設けることができる。この構成によって、方立２の第一中空部Ｓ１の水密状態を安定的に保持できる。 According to the above-mentioned sealing structure 1 of the upright, the lower end of the upright 2 is provided with a wet seal filling section 3, so that the wet sealant 5 can be filled from the lower end opening 29 of the upright 2. The wet sealant 5 can be provided on at least a portion of the lower end of the upright 2 in the projection direction D. With this configuration, the watertight state of the first hollow section S1 of the upright 2 can be stably maintained.

上記方立のシール構造１によれば、方立２の側壁６１に貫通孔７が形成されている。貫通孔７は湿式シール充填部３の充填端部である上端部３１に位置する。この結果、湿式シール材５の充填時、貫通孔７から湿式シール材５が溢れ出ると、作業者は湿式シール充填部３に湿式シール材５が十分に充填されたことが認識できる。 According to the upright sealing structure 1, a through hole 7 is formed in the side wall 61 of the upright 2. The through hole 7 is located at the upper end 31, which is the filling end of the wet seal filling section 3. As a result, when the wet sealant 5 is filled, if the wet sealant 5 overflows from the through hole 7, the worker can recognize that the wet seal filling section 3 has been sufficiently filled with the wet sealant 5.

上記方立のシール構造１によれば、湿式シール充填部３の上方に乾式シール部材４２が設けられている。この結果、湿式シール材５と乾式シール部材４２とが上下方向Ｈに連続して設けられ、第一中空部Ｓ１の封止状態を安定的に保持できる。乾式シール部材４２の下端面４２１が湿式シール充填部３の天面として機能する。この構成によって、湿式シール充填部３に湿式シール材５を充填する作業が容易に行える。 According to the upright seal structure 1, the dry seal member 42 is provided above the wet seal filling section 3. As a result, the wet seal material 5 and the dry seal member 42 are provided continuously in the vertical direction H, and the sealed state of the first hollow section S1 can be stably maintained. The lower end surface 421 of the dry seal member 42 functions as the top surface of the wet seal filling section 3. This configuration makes it easy to fill the wet seal filling section 3 with the wet seal material 5.

上記方立のシール構造１によれば、湿式シール充填部３の上方に乾式シール部材４２が設けられ、湿式シール充填部３の上端部３１に連通する貫通孔７が方立２の側壁６１に形成されている。乾式シール部材４２の下端面４２１が湿式シール充填部３の天面として機能する。湿式シール充填部３内に湿式シール材５を充填する時、天面に到達した湿式シール材５が横方向に流れ貫通孔７から方立２の外部に溢れ出る。この結果、作業者は湿式シール充填部３内に湿式シール材５が十分に充填されたことを速やかに確認でき、充填作業が効率的に行える。 According to the above-mentioned upright sealing structure 1, a dry sealing member 42 is provided above the wet seal filling section 3, and a through hole 7 that communicates with the upper end 31 of the wet seal filling section 3 is formed in the side wall 61 of the upright 2. The lower end surface 421 of the dry sealing member 42 functions as the top surface of the wet seal filling section 3. When the wet sealant 5 is filled into the wet seal filling section 3, the wet sealant 5 that reaches the top surface flows laterally and overflows from the through hole 7 to the outside of the upright 2. As a result, the worker can quickly confirm that the wet sealant 5 has been sufficiently filled into the wet seal filling section 3, and the filling work can be performed efficiently.

上記方立のシール構造１によれば、湿式シール充填部３の上方および見込方向Ｄの室内Ｉ側に乾式端部シール部材４１および乾式シール部材４１が設けられている。この結果、湿式シール充填部３の上方および見込方向Ｄの室内Ｉ側の仕切部を簡易な構成で形成できる。湿式シール充填部３の上方および見込方向Ｄの室内Ｉ側において、乾式端部シール部材４１および乾式シール部材４１と湿式シール材５とが連続して設けられる。この構成によって、方立２の下端開口２９の封止状態が安定的に保持される。 According to the upright seal structure 1, a dry end seal member 41 and a dry seal member 41 are provided above the wet seal filling section 3 and on the room I side in the prospective direction D. As a result, a partition section above the wet seal filling section 3 and on the room I side in the prospective direction D can be formed with a simple configuration. Above the wet seal filling section 3 and on the room I side in the prospective direction D, the dry end seal member 41 and the dry seal member 41 and the wet sealant 5 are provided continuously. With this configuration, the sealing state of the lower end opening 29 of the upright 2 is stably maintained.

上記方立のシール構造１によれば、方立２の下方に、幅方向Ｗに隣り合う水切部８２１同士の隙間Ｘが形成される。この結果、隙間Ｘが湿式シール材５の充填具の通過部として機能し、湿式シール材５の充填作業が容易に行える。 According to the upright sealing structure 1, a gap X is formed below the upright 2 between adjacent drainage sections 821 in the width direction W. As a result, the gap X functions as a passage for the filler of the wet sealant 5, making it easy to fill the wet sealant 5.

上記方立のシール方法によれば、方立２の下端開口２９に連続する湿式シール充填部３を形成し、方立２の側壁６１に貫通孔７を形成する。下端開口２９から湿式シール材５を充填する。この方法によって、施工現場で、方立２の下方から湿式シール材５を充填する作業が容易に行える。 According to the above-mentioned method for sealing the mullions, a wet seal filling section 3 is formed that is continuous with the lower end opening 29 of the mullions 2, and a through hole 7 is formed in the side wall 61 of the mullions 2. The wet sealant 5 is filled from the lower end opening 29. This method makes it easy to fill the wet sealant 5 from below the mullions 2 at the construction site.

方立２の形状は図示例に限定されない。上記実施形態の方立２の第一部品２１および第二部品２２の連結構造等は一例である。本開示の方立２のシール構造１および方立２のシール方法は、上下方向Ｈの端部に端部開口を有し、端部開口に近傍に中空部が形成された方立２において好適に採用できる。 The shape of the mullion 2 is not limited to the illustrated example. The connection structure of the first part 21 and the second part 22 of the mullion 2 in the above embodiment is one example. The sealing structure 1 of the mullion 2 and the sealing method of the mullion 2 disclosed herein can be suitably used in a mullion 2 that has an end opening at the end in the vertical direction H and has a hollow portion formed near the end opening.

上記実施形態では、方立２の下端部に湿式シール充填部が設けられた例を示したが、方立２の上端部に湿式シール充填部が設けられていてもよい。例えば、方立２の上端部および下端部が水平方向の直線を中心とした線対称形状に構成されていてもよい。方立２の外側凸部の上端は、方立２の上端より下方に位置する。内側凸部の上端は、方立２の上端より下方に位置する。内側凸部の上端の高さは、外側凸部の上端より低い。方立２の上端開口と外側凸部の上端との間に湿式シール充填部が設けられる。 In the above embodiment, an example was shown in which a wet seal filling portion was provided at the lower end of the mullion 2, but a wet seal filling portion may also be provided at the upper end of the mullion 2. For example, the upper and lower ends of the mullion 2 may be configured in a shape that is linearly symmetrical about a horizontal straight line. The upper end of the outer convex portion of the mullion 2 is located below the upper end of the mullion 2. The upper end of the inner convex portion is located below the upper end of the mullion 2. The height of the upper end of the inner convex portion is lower than the upper end of the outer convex portion. A wet seal filling portion is provided between the upper end opening of the mullion 2 and the upper end of the outer convex portion.

上記実施形態では、方立２の側壁に２箇所の貫通孔７が形成された例を示したが、貫通孔７の数は限定されない。貫通孔は湿式シール充填部の上部に一以上形成されていれば、湿式シール材が溢れ出ることを認識する効果が得られる。 In the above embodiment, an example was shown in which two through holes 7 were formed in the side wall of the mullion 2, but the number of through holes 7 is not limited. If one or more through holes are formed in the upper part of the wet seal filling part, the effect of recognizing that the wet seal material is overflowing can be obtained.

上記実施形態では、天面として機能する乾式シール部材４２と貫通孔７との両方を備える例を示したが、両方を備える例に限定されない。方立２のシール構造１は、貫通孔７のみ備える構成であっても、作業者が湿式シール材５の充填状況を認識できる。方立２のシール構造１は、貫通孔７を備えず、湿式シール充填部３の上方に乾式シール部材４２を設ける構成のみであっても、作業者が湿式シール材５の充填状況を認識できる。この場合、乾式シール部材４２に到達するまで湿式シール材５を充填すると、乾式シール部材４２の下端面４２１によって湿式シール材５が堰き止められる。湿式シール充填部３が湿式シール材５で満たされると、湿式シール材５が下端開口２９から溢れ出る。この結果、作業者は、湿式シール充填部３に湿式シール材５が十分に充填されたことを認識できる。 In the above embodiment, an example is shown in which both the dry seal member 42 functioning as the top surface and the through hole 7 are provided, but the present invention is not limited to the example in which both are provided. Even if the seal structure 1 of the upright 2 is configured to have only the through hole 7, the worker can recognize the filling status of the wet seal material 5. Even if the seal structure 1 of the upright 2 is configured to have only the dry seal member 42 above the wet seal filling portion 3 without the through hole 7, the worker can recognize the filling status of the wet seal material 5. In this case, when the wet seal material 5 is filled until it reaches the dry seal member 42, the wet seal material 5 is blocked by the lower end surface 421 of the dry seal member 42. When the wet seal filling portion 3 is filled with the wet seal material 5, the wet seal material 5 overflows from the lower end opening 29. As a result, the worker can recognize that the wet seal filling portion 3 is sufficiently filled with the wet seal material 5.

貫通孔７は、上記実施形態のように湿式シール充填部３の上端部３１に開口する例に限定されない。貫通孔７は、湿式シール充填部３の奥側である充填端部まで湿式シール材５が充填されたことを認識可能に設けられればよく、湿式シール充填部３の充填端部に開口する構成であればよい。貫通孔７は、方立２の端部から上下方向Ｈの中央側に離れた位置であって、湿式シール充填部３の端部に設けられていればよい。例えば、方立２の上部に湿式シール充填部３が設けられる場合、貫通孔７は方立２の側壁６１の上部に湿式シール充填部３の下端部に向かって貫通する貫通孔が形成されていてもよい。例えば、貫通孔７は、方立２の側壁のうち、湿式シール充填部３の上下方向Ｈおよび見込方向Ｄの両方の充填端部に連通する位置にそれぞれ形成してもよい。 The through hole 7 is not limited to the example in which it opens at the upper end 31 of the wet seal filling section 3 as in the above embodiment. The through hole 7 may be provided so as to be able to recognize that the wet sealant 5 has been filled up to the filling end, which is the back side of the wet seal filling section 3, and may be configured to open at the filling end of the wet seal filling section 3. The through hole 7 may be provided at a position away from the end of the upright 2 toward the center in the vertical direction H, at the end of the wet seal filling section 3. For example, when the wet seal filling section 3 is provided at the top of the upright 2, the through hole 7 may be formed as a through hole that penetrates toward the lower end of the wet seal filling section 3 at the upper part of the side wall 61 of the upright 2. For example, the through hole 7 may be formed at a position in the side wall of the upright 2 that communicates with both the filling ends of the wet seal filling section 3 in the vertical direction H and the prospective direction D.

上記実施形態では、方立２の中空部が三つの中空部Ｓ１，Ｓ２，Ｓ３に分けられた例を示したが、方立２の中空部の態様は上述の例に限定されない。方立２の室外側の中空部を安定的に封止できればよい。例えば、室外Ｏ側と室内Ｉ側とで中空部が分割された２つの中空部を備える方立であってもよい。例えば、四つ以上に分割された中空部を備える方立であってもよい。 In the above embodiment, an example was shown in which the hollow portion of the mullion 2 was divided into three hollow portions S1, S2, and S3, but the form of the hollow portion of the mullion 2 is not limited to the above example. It is sufficient that the hollow portion on the outdoor side of the mullion 2 can be stably sealed. For example, the mullion may have two hollow portions, with the hollow portion divided on the outdoor O side and the indoor I side. For example, the mullion may have a hollow portion divided into four or more parts.
