Description

[Technical Field]

[0001] The present invention relates to a curtain wall unit that guides a rising and falling gondola with a guide portion. [Background technology]

[0002] Curtain wall units are installed side by side in the left-right and up-down directions to form the exterior walls of a building. Gondolas are sometimes used on the exterior walls of buildings for maintenance, cleaning, etc. of the curtain wall units. When the gondolas are raised or lowered, they are guided by guide sections provided on the curtain wall units and move up and down along the guide sections. Conventionally, curtain walls that guide the gondolas using guide rails as guide sections are known (see Patent Document 1).

[0003] In the conventional curtain wall described in Patent Document 1, the seal receiving member mounting bracket is fixed to the bottom of the mullion with screws, and the mullion-side seal receiving member is attached to the seal receiving member mounting bracket with screws. The guide rail is formed on the mullion-side seal receiving member, which is a separate component from the mullion, and guides the gondola guide car. As with this conventional mullion-type curtain wall, even in curtain wall units, the guide portion may be provided on a separate component from the vertical frame. In this case, the guide portion is provided on the gondola guide frame, and the gondola guide frame is fixed to the vertical frame with fasteners such as screws. However, when an external force acts on the gondola guide frame, there is a concern that shear load will act on the fastener due to the gondola guide frame and the vertical frame. Therefore, in order to stably attach the gondola guide frame to the vertical frame, for example, the shear strength of the fastener must be increased. Accordingly, improvements are needed to overcome the limitations of the fastener. [Prior art documents] [Patent documents]

[0009] An embodiment of the curtain wall unit of the present invention will be described with reference to the drawings. The curtain wall unit of this embodiment is used for the curtain wall of a building and is installed on the exterior wall of the building. Multiple curtain wall units are combined with each other to form part of the curtain wall. The curtain wall units and curtain wall are installed on the exterior wall of the building, between the indoor (indoor) and outdoor (outdoor) sides of the building, to form the exterior wall of the building.

[0010] FIG. 1 is a front view showing the curtain wall 1 of this embodiment, showing the curtain wall 1 and curtain wall unit 2 installed in a building 10 as viewed from the outdoor side. FIG. 2 is a longitudinal cross-sectional view showing the curtain wall 1 of this embodiment, showing the curtain wall 1 and a part of the building 10 cut along line X1-X1 in FIG. 1. FIG. 3 is a transverse cross-sectional view showing the curtain wall 1 of this embodiment, showing the curtain wall 1 cut along line X2-X2 in FIG. 1.

[0011] As shown in the figure, the curtain wall 1 comprises a plurality of curtain wall units 2 installed side by side on a building 10. The curtain wall units 2 are panel units that make up the curtain wall 1, and are pre-assembled before installation on the building 10. The curtain wall 1 and the curtain wall units 2 are installed in locations on the exterior wall 11 of the building 10, and form the exterior wall 11 of the building 10. The curtain wall units 2 are installed side by side in the vertical direction R and the horizontal direction S, and are connected to each other with adjacent curtain wall units 2. The curtain wall 1 and the curtain wall units 2 are arranged on the outdoor side of the skeleton 12 of the building 10, and are attached to the skeleton 12 of the building 10.

[0012] When the curtain wall 1 and the curtain wall unit 2 installed in the building 10 are viewed from the front, the up-down direction is the up-down direction R, and the left-right direction is the left-right direction S. In FIG. 1, the up-down direction R is the vertical direction, and the left-right direction S is the horizontal direction. The indoor-outdoor direction T is the indoor-outdoor direction (indoor-outdoor direction) of the curtain wall 1 and the curtain wall unit 2 installed in the building 10. Furthermore, the indoor-outdoor direction T is the front-to-back direction (depth direction) and the thickness direction of the curtain wall 1 and the curtain wall unit 2 when viewed from the front of the curtain wall 1 and the curtain wall unit 2 installed in the building 10, and in FIG. 3 is the horizontal direction perpendicular to the left-to-right direction S. Thus, the directions of the curtain wall 1 and the curtain wall unit 2 are specified by the directions when they are installed in the building 10. Furthermore, the indoor side and the outdoor side of the curtain wall 1 and the curtain wall unit 2 are the indoor side and the outdoor side when they are installed in the building 10.

[0013] The curtain wall unit 2 comprises two upper and lower panels 2A and a frame 3 surrounding the panels 2A. The panels 2A are rectangular glass panels (for example, plate glass, double-glazed glass, or laminated glass) that are placed in openings 3A in the frame 3 and are held by the frame 3. The panels 2A are fixed panels that are fixed to the rectangular openings 3A in the frame 3 and close the openings 3A in the frame 3. The frame 3 is a rectangular opening frame that forms the openings 3A, and is placed on the outdoor side of the skeleton 12 of the building 10 and attached to the skeleton 12 of the building 10.

The second fixing device 61 passes through the second fixing portion 44 of the gondola guide frame 40, the second transmission part 80, and the second connecting portion 6G of the vertical frame 6, and fixes and connects the second fixing portion 44 of the gondola guide frame 40 to the second connecting portion 6G of the vertical frame 6. The second back plate 63 is located on the lateral side (the recessed portion 6C side) of the second connecting portion 6G of the vertical frame 6, and the second fixing device 61 is attached to the second back plate 63.

[0041] The transmission parts 70, 80 are restricting parts that restrict the shear of the fixing devices 60, 61, and are arranged adjacent to the fixing devices 60, 61, and come into contact with the gondola guide frame 40 and the vertical frame 6. If the curtain wall unit 2 does not have the transmission parts 70, 80, when an external force acting on the gondola guide frame 40 in a direction intersecting the axial direction of the fixing devices 60, 61 acts on the gondola guide frame 40, a shear load acts on the fixing devices 60, 61 from the gondola guide frame 40 and the vertical frame 6. The shear load is a load (shear force) that acts on the fixing devices 60, 61 from the gondola guide frame 40 and the vertical frame 6, and attempts to shear the fixing devices 60, 61; in this case, it is a load in a direction intersecting the axial direction of the fixing devices 60, 61. When an external force acts on the gondola guide frame 40, the transmission parts 70, 80 transmit the load from the gondola guide frame 40 to the vertical frame 6, and regulate the shear load from the gondola guide frame 40 and the vertical frame 6 to act on the fixing devices 60, 61.

[0042] The transmission parts 70, 80 are arranged between the gondola guide frame 40 and the vertical frame 6, and are sandwiched between the gondola guide frame 40 and the vertical frame 6. In this state, the transmission parts 70, 80 receive a load from the gondola guide frame 40 and transmit the load applied to the gondola guide frame 40 to the vertical frame 6. The transmission parts 70, 80 transmit a load in a direction that shears the fasteners 60, 61 from the gondola guide frame 40 to the vertical frame 6, and the vertical frame 6 receives the load transmitted from the gondola guide frame 40. The vertical frame 6 receives the load acting from the gondola guide frame 40 via the transmission parts 70, 80 and supports the gondola guide frame 40. The transmission parts 70, 80 regulate the application (action) of the shear load to the fasteners 60, 61 and the shearing of the fasteners 60, 61.

[0043] Here, when an external force acting on the gondola guide frame 40 in a direction intersecting the axial direction of the fixing devices 60, 61, the load is transmitted from the gondola guide frame 40 to the vertical frame 6 by the transmission parts 70, 80. This prevents a shear load acting on the fixing devices 60, 61 in a direction intersecting the axial direction of the fixing devices 60, 61. The transmission parts 70, 80 prevent the shear load from acting on the fixing devices 60, 61, thereby preventing shear damage to the fixing devices 60, 61. Furthermore, the fixing devices 60, 61 maintain the gondola guide frame 40 in a fixed state to the vertical frame 6, and the gondola guide frame 40 is stably attached to the vertical frame 6.

[0044] The first transmission part 70 is an outdoor-side transmission part located closer to the outdoors than the second transmission part 80, and is arranged between the first connecting part 6F of the vertical frame 6 and the first fixing part 43 of the gondola guide frame 40 in the indoor-outdoor direction T, and is in contact with the first connecting part 6F of the vertical frame 6 and the first fixing part 43 of the gondola guide frame 40. The second transmission part 80 is an indoor-side transmission part located closer to the indoors than the first transmission part 70, and is arranged between the second connecting part 6G of the vertical frame 6 and the second fixing part 44 of the gondola guide frame 40 in the left-right direction S, and is in contact with the second connecting part 6G of the vertical frame 6 and the second fixing part 44 of the gondola guide frame 40.

[0045] The first fixing device 60 penetrates the vertical frame 6 (first connecting portion 6F), the first transmission part 70, and the gondola guide frame 40 (first fixing part 43) in the indoor / outdoor direction T, and fixes the gondola guide frame 40 to the vertical frame 6. The axial direction of the first fixing device 60 is the indoor / outdoor direction T, and the shear load of the first fixing device 60 is a load in the left-right direction S. For example, when the guide part 41 of the gondola guide frame 40 is pressed by the guide roller 21 of the gondola 20, an external force (load) in the left-right direction S acts on the gondola guide frame 40. In this way, when an external force in the left-right direction S (here, external forces in both directions in the left-right direction S) acts on the gondola guide frame 40, the first transmission part 70 transmits the load in the left-right direction S from the gondola guide frame 40 to the vertical frame 6, thereby restricting the shear load in the left-right direction S from acting on the first fixing device 60. The first transmission component 70 restricts and prevents the first fixing device 60 from being sheared in the left-right direction S.

[0046] The second fixing device 61 penetrates the gondola guide frame 40 (second fixing portion 44), the second transmission part 80, and the vertical frame 6 (second connecting part 6G) in the left-right direction S, and fixes the gondola guide frame 40 to the vertical frame 6. The axial direction of the second fixing device 61 is the left-right direction S, and the shear load of the second fixing device 61 is a load in the indoor-outdoor direction T. For example, when outdoor pressure is applied to the panel 2A, an external force (load) in a direction toward the outdoor side in the indoor-outdoor direction T (outdoor direction) acts from the panel 2A to the batten 30 on the gondola guide frame 40. In this way, when an external force in the indoor-outdoor direction T (here, an external force in the outdoor direction) acts on the gondola guide frame 40, the second transmission part 80 transmits the load in the indoor-outdoor direction T from the gondola guide frame 40 to the vertical frame 6, thereby restricting the shear load in the indoor-outdoor direction T from acting on the second fixing device 61. The second transmission component 80 restricts and prevents the second fastener 61 from being sheared in the indoor / outdoor direction T.

[0047] Each of the transmission parts 70, 80 has a first transmission member 71, 81 that is engaged with the gondola guide frame 40 and a second transmission member 72, 82 that is engaged with the vertical frame 6. The first transmission member 71 and the second transmission member 72 of the first transmission part 70 are combined with each other to form a restricting member that restricts shearing of the first fixing device 60, and the first transmission member 81 and the second transmission member 82 of the second transmission part 80 are combined with each other to form a restricting member that restricts shearing of the second fixing device 61. In addition, the first transmission members 71, 81 are gondola guide frame-side transmission members that are attached to the fixing parts 43, 44 of the gondola guide frame 40, and are in contact with the fixing parts 43, 44 of the gondola guide frame 40. The second transmission members 72, 82 are vertical frame side transmission members attached to the connecting portions 6F, 6G of the vertical frame 6, and come into contact with the connecting portions 6F, 6G of the vertical frame 6 to receive the first transmission members 71, 81. The first transmission members 71, 81 receive a load from the gondola guide frame 40 and transmit the load to the second transmission members 72, 82. The second transmission members 72, 82 receive a load from the first transmission members 71, 81 and transmit the load to the vertical frame 6.

[0048] The transmission parts 70, 80 have spacer parts 73, 83 that are sandwiched between the fixing parts 43, 44 of the gondola guide frame 40 and the vertical frame 6 (here, connecting parts 6F, 6G). The spacer part 73 of the first transmission part 70 is a part of the first transmission material 71 and is formed on the first transmission material 71. The spacer part 83 of the second transmission part 80 is a part of the first transmission material 81 and a part of the second transmission material 82 and is formed on each of the first transmission material 81 and the second transmission material 82. The spacer parts 73, 83 are arranged between the fixing parts 43, 44 of the gondola guide frame 40 and the vertical frame 6 at the locations where the fixing parts 43, 44 of the gondola guide frame 40 are fixed to the vertical frame 6 by the fixing devices 60, 61, and the spacer parts 73, 83 maintain the distance between the fixing parts 43, 44 of the gondola guide frame 40 and the vertical frame 6. The fixing members 60, 61 are inserted through insertion holes formed in the spacer portions 73, 83. The spacer portions 73, 83 are positioned around the fixing members 60, 61 inside the insertion holes and surround the fixing members 60, 61.

[0049] The spacer portion 73 of the first transmission component 70 is sandwiched between the first fixing portion 43 of the gondola guide frame 40 and the vertical frame 6 (first connecting portion 6F) in the indoor / outdoor direction T. When an external force in the axial direction of the first fixing device 60 (indoor / outdoor direction T) acts on the gondola guide frame 40, the load in the axial direction of the first fixing device 60 is transmitted from the first fixing portion 43 of the gondola guide frame 40 to the vertical frame 6 via the spacer portion 73. Here, the external force and load in the axial direction of the first fixing device 60 are external force and load in the direction in which the first fixing portion 43 of the gondola guide frame 40 approaches the vertical frame 6 (outdoor direction) in the axial direction of the first fixing device 60. The vertical frame 6 receives the load acting from the first fixing portion 43 of the gondola guide frame 40 via the spacer portion 73 and supports the first fixing portion 43 of the gondola guide frame 40 in the indoor / outdoor direction T.

[0050] The spacer portion 83 of the second transmission component 80 is sandwiched between the second fixing portion 44 of the gondola guide frame 40 and the vertical frame 6 (second connecting portion 6G) in the left-right direction S. When an external force in the axial direction (left-right direction S) of the second fixing device 61 acts on the gondola guide frame 40, the load in the axial direction of the second fixing device 61 is transmitted from the second fixing portion 44 of the gondola guide frame 40 to the vertical frame 6 via the spacer portion 83. Here, the external force and load in the axial direction of the second fixing device 61 are external force and load in a direction in which the second fixing portion 44 of the gondola guide frame 40 approaches the vertical frame 6 in the axial direction of the second fixing device 61. The vertical frame 6 receives the load acting from the second fixing portion 44 of the gondola guide frame 40 via the spacer portion 83 and supports the second fixing portion 44 of the gondola guide frame 40 in the left-right direction S.

[0051] In the first transmission component 70, the first transmission member 71 and the second transmission member 72 abut against each other between the first fixing portion 43 of the gondola guide frame 40 and the vertical frame 6 (first connecting portion 6F), and the load is transmitted from the first transmission member 71 to the second transmission member 72. In the second transmission component 80, the first transmission member 81 and the second transmission member 82 abut against each other between the second fixing portion 44 of the gondola guide frame 40 and the vertical frame 6 (second connecting portion 6G), and the load is transmitted from the first transmission member 81 to the second transmission member 82. In addition, the first transmission members 71 and 81 have locking portions 74 and 84 and abutting portions 75 and 85, respectively, and the second transmission members 72 and 82 have locking portions 76 and 86 and abutting portions 77 and 87, respectively.

[0052] The first transmission member 71 of the first transmission component 70 is sandwiched between the first connecting portion 6F of the vertical frame 6 and the first fixing portion 43 of the gondola guide frame 40 in the indoor-outdoor direction T. The locking portion 74 of the first transmission member 71 is a protrusion (locking protrusion) that protrudes toward the indoor side and abuts against the gondola guide frame 40. The gondola guide frame 40 has a locking receiving portion 46 that is arranged toward the outdoor side and locks with the locking portion 74. The locking receiving portion 46 is a groove portion (locking groove portion) that extends in the longitudinal direction of the gondola guide frame 40 and is formed adjacent to the first fixing portion 43 of the gondola guide frame 40 and is open toward the outdoor side. The locking portion 74 is inserted into the locking receiving portion 46 from the outdoor side, received in the locking receiving portion 46, and locked to the locking receiving portion 46. The locking portion 74 and the first transmission member 71 are locked to the lock receiving portion 46 and the gondola guide frame 40. The abutting portion 75 of the first transmission member 71 is part of the spacer portion 73 and abuts against the vertical frame 6 and the second transmission member 72.

[0053] The second transmission member 72 of the first transmission component 70 is sandwiched between the head of the first fastener 60, which is a screw, and the vertical frame 6 on the outdoor side of the vertical frame 6 (first connecting portion 6F), and is fixed to the vertical frame 6 by the first fastener 60. The locking portion 76 and the abutting portion 77 of the second transmission member 72 are protruding pieces that protrude toward the outdoor side and are formed continuously in the indoor-outdoor direction T. The vertical frame 6 has a locking receiving portion 6I that locks with the locking portion 76. The locking receiving portion 6I is an insertion hole formed in the vertical frame 6 (here, the first connecting portion 6F) and penetrates the first connecting portion 6F in the indoor-outdoor direction T. The locking portion 76 and the abutting portion 77 are inserted through the locking receiving portion 6I, and the locking portion 76 is positioned inside the locking receiving portion 6I. In this state, the locking portion 76 is received in and locked by the locking receiving portion 6I. The locking portion 76 and the second transmission member 72 are locked to the locking receiving portion 6I and the vertical frame 6. The abutting portion 77 protrudes from the locking portion 76, the locking receiving portion 6I, and the first connecting portion 6F toward the indoor side and abuts against the abutting portion 75 of the first transmission member 71.

[0054] The gondola guide frame 40 transmits a load in a direction intersecting the axial direction of the first fixing device 60 to the locking portion 74 and the first transmission member 71. In this case, the direction intersecting the axial direction of the first fixing device 60 is the left-right direction S, and the gondola guide frame 40 transmits loads in both directions in the left-right direction S to the locking portion 74 and the first transmission member 71. The first transmission member 71 transmits a load in one direction in the direction intersecting the axial direction of the first fixing device 60 to the vertical frame 6 by the abutting portion 75, and transmits a load in the other direction in the direction intersecting the axial direction of the first fixing device 60 to the vertical frame 6 via the second transmission member 72.

[0055] The vertical frame 6 has a receiving portion 6J that receives the abutment portion 75. The receiving portion 6J is a protrusion (receiving protrusion) that protrudes toward the indoor side. The abutment portion 75 of the first transmission member 71 is disposed between the receiving portion 6J of the vertical frame 6 and the abutment portion 77 of the second transmission member 72, and abuts and hooks onto the receiving portion 6J of the vertical frame 6 and the abutment portion 77 of the second transmission member 72, respectively. The second transmission member 72 receives the load transmitted from the abutment portion 75 and the first transmission member 71 via the abutment portion 77, and transmits the load to the vertical frame 6 via the locking portion 76. The vertical frame 6 receives the load transmitted from the abutment portion 75, the first transmission member 71, and the first transmission part 70 via the receiving portion 6J, and receives the load transmitted from the locking portion 76, the second transmission member 72, and the first transmission part 70 via the locking receiving portion 6I, which is a load receiving portion. In this way, the vertical frame 6 receives the load acting from the gondola guide frame 40 via the first transmission component 70 and supports the gondola guide frame 40.

[0056] In the second transmission component 80, the abutment portion 85 of the first transmission member 81 and the second transmission member 82 are sandwiched in the left-right direction S between the second connecting portion 6G of the vertical frame 6 and the second fixing portion 44 of the gondola guide frame 40. The locking portion 84 of the first transmission member 81 is a protrusion (locking protrusion) that protrudes in the left-right direction S and abuts against the gondola guide frame 40. The gondola guide frame 40 has a locking receiving portion 47 that locks the locking portion 84. The locking receiving portion 47 is an insertion hole formed in the gondola guide frame 40 (here, the second fixing portion 44) and penetrates the second fixing portion 44 in the left-right direction S. The locking portion 84 is inserted through the locking receiving portion 47 and is positioned inside the locking receiving portion 47. In this state, the locking portion 84 is received in the locking receiving portion 47 and is locked by the locking receiving portion 47. The locking portion 84 and the first transmission member 81 are locked to the lock receiving portion 47 and the gondola guide frame 40. The abutting portion 85 is sandwiched between the second fixing portion 44 of the gondola guide frame 40 and the second transmission member 82, and abuts against the abutting portion 87 of the second fixing portion 44 of the gondola guide frame 40 and the second transmission member 82.

[0057] In the second transmission member 82 of the second transmission part 80, the locking portion 86 is a protrusion (locking protrusion) that protrudes in the left-right direction S and abuts against the vertical frame 6. The vertical frame 6 has a locking receiving portion 6K that locks with the locking portion 86. The locking receiving portion 6K is a groove (locking groove) that extends in the longitudinal direction of the vertical frame 6, is formed adjacent to the second connecting portion 6G of the vertical frame 6, and is open toward the side where the second transmission part 80 is located in the left-right direction S. The locking portion 86 is inserted into the locking receiving portion 6K, is received in the locking receiving portion 6K, and is locked by the locking receiving portion 6K. The locking portion 86 and the second transmission member 82 are locked to the locking receiving portion 6K and the vertical frame 6. The contact portion 87 protrudes toward the gondola guide frame 40 in the left-right direction S, and the contact portion 85 of the first transmission member 81 contacts and is caught on the contact portion 87 of the second transmission member 82.

[0058] The gondola guide frame 40 transmits a load in a direction intersecting the axial direction of the second fixing device 61 to the locking portion 84 and the first transmission member 81 via the locking receiving portion 47. Here, the direction intersecting the axial direction of the second fixing device 61 is the indoor-outdoor direction T, and the gondola guide frame 40 transmits a load in the outdoor direction in the indoor-outdoor direction T to the locking portion 84 and the first transmission member 81. The first transmission member 81 transmits a load in one direction (outdoor direction) in the direction intersecting the axial direction of the second fixing device 61 to the abutting portion 87 and the second transmission member 82 via the abutting portion 85. The second transmission member 82 receives the load transmitted from the abutting portion 85 and the first transmission member 81 via the abutting portion 87, and transmits the load to the vertical frame 6 via the locking portion 86. The vertical frame 6 receives the load transmitted from the locking portion 86, the second transmission member 82, and the second transmission part 80 through the locking receiving part 6K, which is a load receiving part. In this way, the vertical frame 6 receives the load acting from the gondola guide frame 40 via the second transmission part 80, and supports the gondola guide frame 40.

[0059] As described above, in the curtain wall unit 2 of this embodiment, the transmission components 70, 80 can restrict shear loads from acting on the fixing devices 60, 61 that fix the gondola guide frame 40 to the vertical frame 6. Therefore, the fixing devices 60, 61 allow the gondola guide frame 40 to be stably attached to the vertical frame 6. Furthermore, the transmission components 70, 80 can transmit loads in the direction that shears the fixing devices 60, 61 from the gondola guide frame 40 to the vertical frame 6, so the gondola guide frame 40 can be fixed to the vertical frame 6 without relying on the shear strength of the fixing devices 60, 61.

[0060] The spacer portions 73, 83 of the transmission parts 70, 80 allow the vertical frame 6 to support the gondola guide frame 40 via the spacer portions 73, 83, while maintaining the distance between the fixing portions 43, 44 of the gondola guide frame 40 and the vertical frame 6. In addition, the receiving portions 6J and the locking receiving portions 6I, 6K of the vertical frame 6 come into contact with the transmission parts 70, 80 and receive the load, and the receiving portions 6J and the locking receiving portions 6I, 6K can stably receive the load transmitted from the transmission parts 70, 80. By locking the first transmission members 71, 81 of the transmission parts 70, 80 to the gondola guide frame 40, the load can be reliably transmitted from the gondola guide frame 40 to the first transmission members 71, 81, and by locking the second transmission members 72, 82 of the transmission parts 70, 80 to the vertical frame 6, the load can be reliably transmitted from the second transmission members 72, 82 to the vertical frame 6. Therefore, the load can be reliably transmitted from the gondola guide frame 40 to the vertical frame 6 via the first transmission members 71, 81 and the second transmission members 72, 82 of the transmission components 70, 80.

[0061] In the first fixing device 60, when a load in the left-right direction S acts on the gondola guide frame 40, the first transmission part 70 can restrict the shear load in the left-right direction S from acting on the first fixing device 60. In addition, in the second fixing device 61, when a load in the indoor / outdoor direction T acts on the gondola guide frame 40, the second transmission part 80 can restrict the shear load in the indoor / outdoor direction T from acting on the second fixing device 61.

[0062] In this embodiment, an example has been described in which the gondola guide frame 40 is fixed to the vertical frame 6 by the first fixing device 60 and the second fixing device 61, but the number of fixing devices is not limited to two and may be one, or three or more. Furthermore, the transmission components 70, 80 may be transmission components consisting of one member (transmission material), or may be transmission components consisting of three or more members (transmission materials). The present invention is not limited to the curtain wall unit 2 having a fixed panel 2A, and can also be applied to various curtain wall units (for example, curtain wall units having openable or movable panels).
