[0041] The second mounting wall portion 242 is provided so as to gradually extend indoors from the indoor end of the first mounting wall portion 241 toward the second mullion body 23 side (one side in the X direction). The second mounting wall portion 242 is disposed on the indoor side of the mounting wall portion 235 of the second mullion body 23. A sealant t4 is disposed between the second mounting wall portion 242 and the mounting wall portion 235. A screw 242a is inserted through the second mounting wall portion 242 and the sealant t4 from the indoor side of the second mounting wall portion 242, and is screwed into the mounting wall portion 235.

[0042] The fitting wall portion 243 is provided so as to gradually extend toward the outdoor side from the outdoor end of the first mounting wall portion 241 toward the second mullion body 23 side (one side in the X direction).

[0043] An engaging claw 243a that engages with the engaging wall portion 237 of the second main body 23 is provided at the end of the engaging wall portion 243.

[0044] In the above-mentioned upright 2A, the first outdoor side wall portion 214 of the first upright member 21 and a part (the outdoor side portion) of the mating wall portion 243 of the joint member 24 and the outdoor side extending wall portion 236 of the second upright main body 23 are arranged on the first water stop line (outdoor side water stop line) A1 along the width direction X and the vertical direction Z.

[0045] The first indoor side wall portion 215 of the first upright member 21 and the indoor side extending wall portion 234 of the second upright body 23 are arranged on a second water stopping line (indoor side water stopping line) A2 along the width direction X and vertical direction Z.

[0046] The first indoor side wall portion 215 of the first upright member 21, the mounting wall portion 235 of the second upright body 23, the indoor side extending wall portion 234 of the second upright body 23, the second mounting wall portion 242 of the joint member 24 and the fitting protrusion 241a of the joint member 24 function as dividing walls that divide the hollow portion s1 in the indoor / outdoor direction Y.

[0047] In the hollow portion s1, the portion on the outdoor side of the second water stop line A2 is divided into spaces s11 to s13n. The space s11 is a space formed in the first glass groove 212 of the first support member 21. The space s12 is a space formed between the second side wall portion 231 of the second support body 23 and the joint member 24. The space s13 is a space formed between the first outdoor side wall portion 214 of the first support member 21, the fitting wall portion 243 of the joint member 24, and the outdoor side extending wall portion 236 of the second support body 23 and the second outdoor wall portion 233 of the second support body 23. In the hollow portion s1, the portion on the outdoor side of the second water stop line A2 is space s14.

[0048] An air communication through hole 214h is formed in the first outdoor side wall portion 214 of the first upright member 21, penetrating in the indoor / outdoor direction. The air communication through hole 214h connects the space s11 and the space s13. The space s11 connects to the outdoors through a drainage hole (not shown) formed in a horizontal member extending in the horizontal direction such as the crosspiece 3. An air communication through hole 243h is formed in the fitting wall portion 243 of the joint member 24, penetrating in the indoor / outdoor direction. The air communication through hole 243h connects the space s12 and the space s13. Therefore, the air pressure in the spaces s11 to s13 is close to the air pressure outside (external pressure). Since there is no difference in air pressure between the spaces s11 to s13 and the outdoors, it is possible to suppress water from being drawn into the spaces s11 to s13, improving watertightness.

[0049] In this embodiment, at least one air communication through-hole 214h, 243h is formed at a height position, for example, about 100 mm above the mesh 3. Taking watertightness into consideration, the size, number and position of the air communication through-holes 214h, 243h are set so that the air pressure in the spaces s11, s12 and the air pressure in the space s13 are close to each other.

[0050] The first water stop line A1 prevents rainwater from infiltrating into the indoor side. The second water stop line A2 prevents the small amount of rainwater that has passed through the first water stop line A1 from infiltrating further into the indoor side (space s14, which is under internal pressure).

[0051] Next, the mullion 2B disposed at the middle portion of the curtain wall 100 in the width direction X will be described. 4, the upright 2B has a first upright member 21 and a third upright member 25. The first upright member 21 and the third upright member 25 are connected to each other to form a hollow space s2 therein. The first upright member 21 used in the upright 2B is the same as the first upright member 21 used in the upright 2A, and the description thereof will be omitted. In the description of the third upright member 25, the same parts as those of the above-mentioned members are given the same reference numerals and the description thereof will be omitted.

[0052] The third partition member 25 has a third side wall portion 251 , a second indoor wall portion 232 , and a second outdoor wall portion 233 .

[0053] The third side wall portion 251 is disposed along the indoor / outdoor direction Y. The third side wall portion 251 is disposed opposite the first side wall portion 211 of the first upright member 21. The third side wall portion 251 extends in the vertical direction Z. The third side wall portion 251 is formed in a plate shape. The plate surface of the third side wall portion 251 faces the width direction X.

[0054] A third glass groove 252 recessed toward the first bracket 21 side (the other side in the X direction) is formed in the third sidewall portion 251. In the third glass groove 252, an end portion 4a of the glass 4 in the width direction X is arranged.

[0055] The third glass groove 252 has a third outdoor side wall portion (outdoor side connecting wall portion) 254 , a third indoor side wall portion (outdoor side connecting wall portion) 255 , and a third bottom wall portion 256 .

[0056] The third exterior side wall portion 254 extends from the third side wall portion 251 towards the first upright member 21 side (the other side in the X direction).

[0057] The third indoor side wall portion 255 extends from the third side wall portion 251 toward the first vertical member 21 side (the other side in the X direction). The third indoor side wall portion 255 is disposed closer to the indoor side than the third outdoor side wall portion 254.

[0058] The third bottom wall portion 256 connects an end portion of the third outdoor side wall portion 254 and an end portion of the third indoor side wall portion 255 .

[0059] An edge 4a of the glass 4 is sandwiched between the third exterior-side wall portion 254 and the third interior-side wall portion 255 via a sealant t1.

[0060] A screw 216 b is inserted from the first glass groove 212 of the first support member 21 through the first bottom wall portion 216 and is screwed into the third bottom wall portion 256 .

[0061] The third bottom wall portion 256 is provided with a pair of fitting protrusions 256a extending toward the first upright member 21 side (the other side in the X direction). The fitting protrusions 256a are arranged spaced apart in the indoor / outdoor direction Y. The pair of fitting protrusions 256a sandwich the fitting protrusion 216a of the first upright member 21.

[0062] The seal material t2 is disposed between the first bottom wall portion 216 of the first upright member 21, the pair of fitting projections 216a, and the third bottom wall portion 256 of the third upright member 25.

[0063] In the curtain wall 100 configured in this manner, no glass groove is formed in the second side wall portion 231 of the second mullion body 23. This prevents water from entering the hollow portion s1 from the second side wall portion 231 side.

[0064] Conventionally, when a groove cover member is placed in a glass groove, the outer edge of the groove cover member appears as a line extending in the vertical direction, but in this embodiment, a second side wall portion 231, which is a flat, single plate material, is placed on the side where the glass 4 is not placed. Therefore, a smart appearance can be achieved without the conventional line appearing.

[0065] The second upright member 22 is configured by connecting separate members, a second upright body 23 and a joint member 24. Therefore, when the second upright body 23 and the joint member 24 are made of aluminum, they are easier to extrude than when they are made of an integral member.

[0066] The space s11 and the space s13 communicate with each other through the air communication through hole 214h formed in the first outdoor side wall portion 214 of the first upright member 21. The space s11 communicates with the outdoors through a drainage hole formed in the cross member. The space s12 and the space s13 communicate with each other through the air communication through hole 243h formed in the fitting wall portion 243 of the joint member 24. Therefore, the air pressure in the spaces s11 to s13 becomes close to the outside air, and the air pressure difference between the air pressure in the spaces s11 to s13 and the outdoors is eliminated, so that it is possible to prevent water from being drawn into the spaces s11 to s13. Even a small amount of water that has entered the space s13 does not enter the space s12, and is prevented from infiltrating into the indoor side beyond the first water stop line A1.

[0067] The first indoor side wall portion 215 of the first mullion member 21 and the indoor side extending wall portion 234 of the second mullion body 23 are arranged on the second water stop line A2. The first indoor side wall portion 215 and the indoor side extending wall portion 234, which are arranged on the second water stop line A2, do not have air communication through holes. A seal material t4 is arranged between the second mounting wall portion 242 and the mounting wall portion 235. As a result, the second water stop line A2 separates the outdoor side spaces s11 to s13 from the outside pressure, and the second water stop line A2 separates the indoor side space s14 from the inside pressure, thereby preventing water from entering the indoor side beyond the second water stop line A2.

[0068] The indoor side of the joint member 24 is connected to the second mullion body 23 with a screw 242a, and the outdoor side of the joint member 24 is engaged with the second mullion body 23 with a fitting claw 243a. Therefore, the wind pressure acting on the glass 4 is transmitted from the glass 4 to the first mullion member 21, then to the joint member 24 connected to the first mullion member 21 with a screw 216b, then to the second mullion body 23 connected to the joint member 24 with the screw 242a and the fitting claw 243a, and then to the framework via the second mullion body 23.

[0069] The screw 216b connecting the first upright member 21 and the joint member 24 and the screw 242a connecting the joint member 24 and the second upright body 23 are disposed inside the hollow portion s1 of the upright 2A. Therefore, the screws 216b and 242a are not exposed to the outside of the upright 2A, and the appearance is good.

[0070] (Variation 1) Next, the mullions (vertical frames) 2C arranged at the ends in the width direction X of the curtain wall 100 according to the first modification of the embodiment shown above will be described mainly with reference to Fig. 5. In the description of the following modification, the same members as those described above are given the same reference numerals and their description will be omitted.

[0071] In this modification, the upright 2C has a first upright member 21 and a second upright member (one-side vertical member) 26. The first upright member 21 and the second upright member 26 are connected to form a hollow space s3 inside. The second upright member 26 in this modification is not connected to the second upright body 23 and the joint member 24 like the second upright member 22, but is constructed as an integrated member.

[0072] The second support member 26 has a second side wall portion 231 , a second indoor wall portion 232 , and a second outdoor wall portion 233 .

[0073] The second side wall portion 231 is provided with a third outdoor side wall portion 254 and a third indoor side wall portion 255. The third outdoor side wall portion 254 is disposed on the first water stop line A1. The third indoor side wall portion 255 is disposed on the second water stop line A2. An end portion of the third outdoor side wall portion 254 and an end portion of the third indoor side wall portion 255 are connected by a third bottom wall portion 256.

[0074] In the curtain wall 100 configured in this manner, no glass groove is formed in the second side wall portion 231 of the second mullion member 26. This prevents water from entering the hollow portion s3 from the second side wall portion 231 side.

[0075] Conventionally, when a groove lid member is placed in a glass groove, the outer edge of the groove lid member appears as a line extending in the vertical direction, but in this embodiment, a second side wall portion 231, which is a flat, single plate material, is placed on the side where the glass 4 is not placed. Therefore, a smart appearance can be achieved without the conventional line appearing.

[0076] (Variation 2) Next, a curtain wall according to Modification 2 of the above-described embodiment will be described mainly with reference to FIG.

[0077] In this modification, the upright (vertical frame) 2D has a first upright member 21 and a second upright member (one-side vertical member) 27. The first upright member 21 and the second upright member 27 are connected to form a hollow space s4 inside. The second upright member 27 in this modification is not connected to the second upright body 23 and the joint member 24 like the second upright member 22, but is configured as an integrated member.

[0078] The second support member 26 has a second side wall portion 231 , a second indoor wall portion 232 , and a second outdoor wall portion 233 .

[0079] The second side wall 231 is provided with an extending wall 271 that extends to the first upright member 21 side (the other side in the X direction). An end 271a of the extending wall 271 is disposed on the indoor side of the pair of engaging protrusions 216a.

[0080] A first mounting wall portion 272 extending toward the outdoor side is provided on the extension wall portion 271. A screw 216b is inserted from the first glass groove 212 of the first stand member 21 to the first bottom wall portion 216 and is screwed into the first mounting wall portion 272.

[0081] In the curtain wall 100 configured in this manner, no glass groove is formed in the second side wall portion 231 of the second mullion member 27. This prevents water from entering the hollow portion s4 from the second side wall portion 231 side.

[0082] Conventionally, when a groove cover member is placed in a glass groove, the outer edge of the groove cover member appears as a line extending in the vertical direction, but in this embodiment, a second side wall portion 231, which is a flat, single plate material, is placed on the side where the glass 4 is not placed. Therefore, a smart appearance can be achieved without the conventional line appearing.

[0083] The shapes and combinations of the components shown in the above-described embodiment are merely examples, and various modifications can be made based on design requirements, etc., without departing from the spirit of this disclosure.

[0084] For example, in the above embodiment, the vertical frame is described as a mullion 2A or the like installed on the curtain wall 100, but the present invention is not limited to this. It is also applicable to a vertical frame installed on a sash of a sliding door or the like. [Explanation of symbols]
