Description

本発明は、方立と横枠によりガラスを保持する建具に関する。 The present invention relates to fittings that hold glass by a mullion and a horizontal frame.

従来、カーテンウォール等の建具において、複数の部材からなる分割式の方立を上下方向に複数配置し、ジョイントスリーブ等を介して連結する技術が知られている。この種の方立を開示するものとして例えば特許文献１がある。特許文献１には、一方側分割方立と他方側分割方立との組み合わせ状態で、他方側分割方立に設けられた室外側タイト材及び室内側タイト材の舌片が一方側分割方立側に接触することにより水密性が確保されることについて記載されている。 Conventionally, in fittings such as curtain walls, there is known a technique of arranging a plurality of split type mullion composed of a plurality of members in the vertical direction and connecting them via a joint sleeve or the like. For example, Patent Document 1 discloses this type of mullion. In Patent Document 1, in a state in which one side split mullion and the other side split mullion are combined, the outdoor tight material and the tongue piece of the indoor tight material provided on the other side split mullion are unilateral split mullion. It is described that watertightness is ensured by contacting the side.

特開２００３−１３８８５２号公報Japanese Unexamined Patent Publication No. 2003-138852

特許文献１に記載されるような方立は、中空部が室外側と室内側に区画される構造となっているが、水密性を確保するためのシール部材（室外側タイト材）により、室外側の中空部が密閉空間となっている。そのため、室外側の空間と外側（大気）の間に圧力差が生じており、方立の湿式シールが切れる等して隙間が生じると、圧力差によって雨水が方立の内部に引き込まれて漏水が生じるおそれがある。排水構造を設けることが考えられるものの、方立ごとに排水構造を形成するための加工を行う必要があり、作業の複雑化やコスト高を招いてしまう。この点、特許文献１においても、ガラス面に負圧や正圧が作用しても十分な抵抗力を示すようにし、分割方立の接合部分に隙間が生じたりしないようにすることができると記載されているものの、方立の中空部の負圧に起因する水の侵入を防止する観点で改善の余地があった。 The mullion as described in Patent Document 1 has a structure in which the hollow portion is divided into the outdoor side and the indoor side, but the chamber is provided with a sealing member (outdoor tight material) for ensuring watertightness. The outer hollow part is a closed space. Therefore, there is a pressure difference between the outdoor space and the outside (atmosphere), and if a gap is created such as when the wet seal of the mullion is broken, rainwater is drawn into the mullion due to the pressure difference and leaks. May occur. Although it is conceivable to provide a drainage structure, it is necessary to process each mullion to form a drainage structure, which complicates the work and increases the cost. In this regard, also in Patent Document 1, it is possible to show sufficient resistance even if negative pressure or positive pressure acts on the glass surface, and to prevent a gap from being generated at the joint portion of the divided mullion. Although it is described, there is room for improvement from the viewpoint of preventing the intrusion of water due to the negative pressure of the hollow part of the mullion.

本発明は、室外と方立内部の圧力差に起因する方立内部への水の侵入を効果的に防止できる建具を提供することを目的とする。 An object of the present invention is to provide a fitting capable of effectively preventing water from entering the mullion due to a pressure difference between the outside and the inside of the mullion.

It has a square (for example, a square 10 described later) and a horizontal glass groove (for example, a horizontal glass groove 310 described later) extending in the lateral direction, and the horizontal glass groove is configured to communicate with the outside of the room. A horizontal frame (for example, a blind 11 described later), a vertical glass groove communicating with each other, and a glass having an end portion accommodated in the horizontal glass groove (for example, a glass 12 described later). The inside of the stand is divided into an outdoor hollow portion (for example, an outdoor hollow portion 301 described later) and an indoor hollow portion (for example, an indoor hollow portion 302 described later), and the outdoor hollow portion and the vertical portion. The present invention relates to a fitting (for example, a curtain wall 2 described later) in which a glass groove communication hole (for example, a glass groove communication hole 251 described later) for communicating the glass groove is formed.

前記建具は、上下方向で連結される上側の方立（例えば、後述の上側方立１０ａ）と下側の方立（例えば、後述の下側方立１０ｂ）の上下方向の隙間に配置される接続部材（例えば、後述の接続部材８０）を更に備え、前記接続部材には、上方に位置する前記方立の前記室外側中空部と下方に位置する前記方立の前記室外側中空部を連通する接続部材連通孔（例えば、後述の接続部材連通孔８１５）が形成されることが好ましい。 The fitting is arranged in a vertical gap between an upper mullion (for example, the upper mullion 10a described later) and a lower mullion (for example, the lower mullion 10b described later) connected in the vertical direction. A connecting member (for example, a connecting member 80 described later) is further provided, and the connecting member communicates the outdoor hollow portion of the mullion located above and the outdoor hollow portion of the mullion located below. It is preferable that a connecting member communication hole (for example, a connection member communication hole 815 described later) is formed.

In the present embodiment, the glass groove communication hole 251 is a processed hole formed by processing after molding the first mullion member 21.

第２方立部材２２の見込面（反対側の面）にもガラス（面材）１２を保持するための縦ガラス溝２２０が形成される。 A vertical glass groove 220 for holding the glass (face material) 12 is also formed on the prospective surface (opposite surface) of the second mullion member 22.

また、第２方立部材２２は、縦ガラス溝２２０を形成する部分以外に縦ガラス溝２２０の室内側で見込面を形成する側壁部２２５と、側壁部２２５から第１方立部材２１側に屈曲して見付方向に沿って延びる室内側壁部２２６と、縦ガラス溝２２０の室外側で方立１０の室外側の見付面を形成する第２壁部２６０と、を備える。 Further, the second mullion member 22 has a side wall portion 225 forming a prospective surface on the indoor side of the vertical glass groove 220 in addition to the portion forming the vertical glass groove 220, and the side wall portion 225 to the first mullion member 21 side. It includes an indoor side wall portion 226 that bends and extends along the finding direction, and a second wall portion 260 that forms the outdoor side finding surface of the mullion 10 on the outdoor side of the vertical glass groove 220.

第２壁部２６０は、平面視において、縦ガラス溝２２０の室外側の端部から折り返すように延びて方立１０の室外側の見付面を形成する。第１方立部材２１と第２方立部材２２が嵌合する嵌合状態において、第２壁部２６０は第１壁部２５０の室外側に位置し、第１壁部２５０と対向する位置関係となる。 In a plan view, the second wall portion 260 extends from the outdoor end of the vertical glass groove 220 so as to fold back to form a mullion 10 outdoor side finding surface.

横ガラス溝３１０，３２０を形成する無目本体部１１１には室外（大気）と連通する室外連通孔４００が形成される。本実施形態では、無目本体部１１１における方立１０の近傍には、左右方向に間隔をあけて二箇所の室外連通孔４００が形成される。これにより、横ガラス溝３１０が大気に連通することになる。なお、本実施形態では、ガラス保持部１１２が無目本体部１１１に連結された状態であっても、室外連通孔４００が室外に連通するように、その位置及び形状が設定されている。 An outdoor communication hole 400 that communicates with the outside (atmosphere) is formed in the transom light body portion 111 that forms the horizontal glass grooves 310 and 320. In the present embodiment, two outdoor communication holes 400 are formed in the vicinity of the mullion 10 in the transom light main body 111 at intervals in the left-right direction. As a result, the horizontal glass groove 310 communicates with the atmosphere. In the present embodiment, the position and shape of the outdoor communication hole 400 are set so that the outdoor communication hole 400 communicates with the outside even when the glass holding portion 112 is connected to the transom light main body portion 111.

方立１０の縦ガラス溝２１０，２２０と、無目１１の横ガラス溝３１０，３２０と、によってガラス１２の端部がシール材１５を介して保持される。縦ガラス溝２１０，２２０と、無目１１の横ガラス溝３１０，３２０と、は互いに連通しており、それぞれが室外連通孔４００を通じて大気に開放されている状態となっている。なお、本実施形態では、ガラス１２は、複層ガラスが用いられているが単板のガラスであってもよい。 The vertical glass grooves 210 and 220 of the mullion 10 and the horizontal glass grooves 310 and 320 of the transom light 11 hold the end portion of the glass 12 via the sealing material 15.

次に、図２〜図４を参照して空気の流通経路９００について説明する。図２〜図４では、空気の流通経路９００が一点鎖線により示されている。上述の通り、室外連通孔４００により、横ガラス溝３１０の内側の空間は室外に連通している。そして、同じガラス１２を保持する横ガラス溝３１０と縦ガラス溝２１０は互いに連通している。従って、室外側中空部３０１は、室外側シール部材４０と区画シール部材４５によって室内側が閉鎖されているものの、縦ガラス溝２１０に連通するガラス溝連通孔２５１により、室外に連通する状態となっている。即ち、室外側中空部３０１は、ガラス溝連通孔２５１、縦ガラス溝２１０、横ガラス溝３１０及び室外連通孔４００を通じて室外に連通しており、大気圧と同じ状態となる。 Next, the air flow path 900 will be described with reference to FIGS. 2 to 4. In FIGS. 2 to 4, the air flow path 900 is indicated by a chain double-dashed line. As described above, the space inside the horizontal glass groove 310 communicates with the outside through the outdoor communication hole 400. The horizontal glass groove 310 and the vertical glass groove 210 that hold the same glass 12 communicate with each other. Therefore, although the indoor side of the outdoor hollow portion 301 is closed by the outdoor sealing member 40 and the partition sealing member 45, the outdoor hollow portion 301 is in a state of communicating with the outside by the glass groove communication hole 251 communicating with the vertical glass groove 210. There is. That is, the outdoor hollow portion 301 communicates with the outside through the glass groove communication hole 251, the vertical glass groove 210, the horizontal glass groove 310, and the outdoor communication hole 400, and is in the same state as the atmospheric pressure.

上記実施形態によれば、以下のような効果を奏する。
カーテンウォール（建具）１は、縦方向に延びる縦ガラス溝２１０を有し、複数の部材を連結して構成される方立１０と、横方向に延びる横ガラス溝３１０を有し、横ガラス溝３１０は室外に連通するように構成される無目（横枠）１１と、互いに連通する縦ガラス溝２１０と横ガラス溝３１０に端部が収容されるガラス１２と、を備え、方立１０は、内部が室外側中空部３０１と室内側中空部３０２に区画されるとともに、室外側中空部３０１と縦ガラス溝２１０を連通するガラス溝連通孔２５１が形成される。 According to the above embodiment, the following effects are obtained.
The curtain wall (joint) 1 has a vertical glass groove 210 extending in the vertical direction, a mullion 10 formed by connecting a plurality of members, and a horizontal glass groove 310 extending in the horizontal direction, and has a horizontal glass groove. The 310 includes a blind (horizontal frame) 11 configured to communicate with the outside, a vertical glass groove 210 communicating with each other, and a glass 12 whose end is accommodated in the horizontal glass groove 310. The inside is divided into an outdoor hollow portion 301 and an indoor hollow portion 302, and a glass groove communication hole 251 that connects the outdoor hollow portion 301 and the vertical glass groove 210 is formed.

これにより、室外側中空部３０１が室外と連通して外圧にできるので、室外側シール部材４０と区画シール部材４５によって閉ざされた状態の室外側中空部３０１が負圧となり、室外側に位置する分割式の方立１０の継ぎ目（嵌合部２１ａと嵌合部２２ａの嵌合部分）から雨水等が引き込まれる事態の発生を防止でき、水密性を効果的に向上させることができる。 As a result, the outdoor hollow portion 301 can communicate with the outdoor to generate an external pressure, so that the outdoor hollow portion 301 in a state of being closed by the outdoor sealing member 40 and the partition sealing member 45 becomes a negative pressure and is located on the outdoor side. It is possible to prevent the occurrence of a situation in which rainwater or the like is drawn in from the joint (fitting portion of the fitting portion 21a and the fitting portion 22a) of the split type mullion 10, and it is possible to effectively improve the watertightness.

また、本実施形態のカーテンウォール２は、上側方立１０ａと下側方立１０ｂの上下方向の隙間に配置される接続部材８０を更に備え、接続部材８０には、上側方立１０ａの室外側中空部３０１と下方に位置する下側方立１０ｂの室外側中空部３０１を連通する接続部材連通孔８１５が形成される。 Further, the curtain wall 2 of the present embodiment further includes a connecting member 80 arranged in a vertical gap between the upper mullion 10a and the lower mullion 10b, and the connecting member 80 is provided on the outdoor side of the upper mullion 10a. A connecting member communication hole 815 that communicates the hollow portion 301 with the outdoor hollow portion 301 of the lower mullion 10b located below is formed.

これにより、たとえ室外側中空部３０１の内部に水が浸入したとしても、区画シール部材４５により区画された室内側中空部３０２に至ることなく接続部材連通孔８１５を通じて下方に落下することになる。下方に配置される排水構造を通じて室外に排水することができるので、室内側への水の侵入をより一層確実に防止できる。 As a result, even if water enters the inside of the outdoor hollow portion 301, it will fall downward through the connecting member communication hole 815 without reaching the indoor hollow portion 302 partitioned by the partition seal member 45. Since the water can be drained to the outside through the drainage structure arranged below, it is possible to prevent water from entering the room more reliably.

また、本実施形態の方立１０は、縦ガラス溝２１０の室外側の内側面を形成する第１壁部２５０を有する第１方立部材２１と、方立１０の見付面を形成し、第１壁部２５０と見込方向で対面する第２壁部２６０を有する第２方立部材２２と、が連結されて構成され、ガラス溝連通孔２５１は、第１壁部２５０に形成される。 Further, the mullion 10 of the present embodiment forms the first mullion member 21 having the first wall portion 250 forming the inner side surface of the outdoor side of the vertical glass groove 210 and the finding surface of the mullion 10. The first wall portion 250 and the second mullion member 22 having the second wall portion 260 facing in the prospective direction are connected to each other, and the glass groove communication hole 251 is formed in the first wall portion 250.

これにより、第１方立部材２１と第２方立部材２２を連結する前の状態では、第１方立部材２１の縦ガラス溝２１０が方立１０の第２壁部２６０の見付面に隠れていない状態となるので、ガラス溝連通孔２５１を現場等で容易に加工できる。 As a result, in the state before connecting the first mullion member 21 and the second mullion member 22, the vertical glass groove 210 of the first mullion member 21 becomes the found surface of the second wall portion 260 of the mullion 10. Since it is not hidden, the glass groove communication hole 251 can be easily processed on site or the like.
