Description

  The present invention relates to a curtain wall, and more particularly to a curtain wall having a gondola rail between vertical frames of adjacent units.

  As a curtain wall, a unit having a frame composed of an upper frame, a lower frame and left and right vertical frames and a panel provided in the frame is arranged adjacent to each other in the left-right direction and the vertical direction, and the adjacent units are opposed to each other. It is known that a gondola rail for guiding a guide roller of a gondola is provided between vertical frames (see Japanese Patent Application Laid-Open No. 2001-275155). In this curtain wall, a gondola rail is fixed to one vertical frame of the opposed vertical frames, and only one vertical frame has a seismic performance against the weight of the gondola.

JP 2001-2751565 A

  However, in the curtain wall, since only one vertical frame has earthquake resistance performance with respect to the weight of the gondola, it is necessary to increase the thickness of the vertical frame to increase the rigidity, resulting in an increase in weight and cost. At the same time, the designability is reduced due to an increase in the size of the appearance.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a curtain wall capable of reducing weight and cost and improving design.

  The present invention is a curtain wall in which a unit having a frame composed of an upper frame, a lower frame and left and right vertical frames and a panel provided in the frame is arranged adjacent to each other in the left-right direction and the vertical direction. A gondola rail portion for guiding a guide roller of the gondola is provided on the opposing vertical frame of the adjacent units, and a connecting member that restrains the tensile force in the horizontal direction between the vertical frames is provided at least in the center in the height direction between the vertical frames. It is provided.

  According to the present invention, a curtain wall comprising a unit having a frame composed of an upper frame, a lower frame, and left and right vertical frames, and a panel provided in the frame, adjacent to each other in the left-right direction and the vertical direction. In addition, a gondola rail portion that guides the guide roller of the gondola is provided in the opposing vertical frame of adjacent units, and at least a central portion in the height direction between the vertical frames is constrained to restrain the horizontal tension between the vertical frames. Since the member is provided, the weight and cost can be reduced and the design can be improved.

  The best mode for carrying out the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a schematic front view of a curtain wall showing an embodiment of the present invention, FIG. 2 is a longitudinal sectional view of the curtain wall, FIG. 3 is a transverse sectional view of the curtain wall, and FIG. FIG. 5 and FIG. 5 are enlarged sectional views taken along the line BB.

  In these drawings, reference numeral 1 denotes a curtain wall which is an outer wall of a high-rise building. The curtain wall 1 includes, for example, an aluminum-shaped upper frame 2, a lower frame 3, and a left and right vertical frame 4 and a frame 5. A unit 7 having a panel 6 provided within 5, for example, a glass panel, is arranged adjacent to each other in the horizontal direction and the vertical direction. For example, as shown in FIG. 2, the unit 7 is mounted so as to be spanned between an end of the upper floor 8a and an end of the lower floor 8b, which is a frame made of a beam of a building. In this case, even if the upper frame 2 portion of the unit 7 is fixed to the end of the floor via the mounting bracket 9, and the lower frame 3 portion of the unit is engaged and connected to the upper frame 2 portion of the lower unit 7 good.

  The opposing vertical frames 4 of the adjacent units 7 have gondola rail portions 12 for guiding the guide rollers 11 of the gondola 10. In the illustrated example, a gondola rail portion 12 for guiding the guide roller 11 of the gondola 10 is formed in the vertical frames 4 and 4 corresponding to the guide roller 11 of the gondola 10 among the vertical frames 4 and 4 of the adjacent units 7 facing each other. The vertical frames 4 and 4 that do not correspond to the guide rollers 11 do not have the gondola rail portion 12 to reduce the weight and cost (see FIG. 4), but all the vertical frames 4 have gondola rail portions. 12 may be formed.

  The gondola 10 is suspended from a crane (not shown) installed on a rooftop so as to be able to move up and down via a wire rope 13 in order to clean the outer wall surface of the curtain wall 1 of a medium- and high-rise building. The gondola 10 has arm portions 14 on the left and right, and a guide roller 11 is rotatably attached to the arm portions 14. The guide roller 11 is positioned between each vertical frame 4 and receives a load in the indoor / outdoor direction, and a pair of left and right first rollers (out-of-plane rollers) 11a, and is positioned between the vertical frames 4 and 4 to apply a load in the horizontal direction. It comprises a second roller (in-plane roller) 11b for receiving. The gondola rail portion 12 is formed, for example, in a substantially U-shaped cross section. In the example of illustration, the 1st rail part 12a of the protrusion which receives the 1st roller 11a, and the 2nd rail 12b of the protrusion which receives the 2nd roller 11b are provided.

  A connecting member that allows relative movement in the vertical direction of the vertical frames 4 and 4 between the vertical frames 4 and 4 and restrains the horizontal frames between the vertical frames 4 and 4 in the vertical direction. 14 is provided. In the illustrated example, a connecting member 14 is provided between the vertical frames 4 and 4 having the gondola rail portion 12, and no connecting member 14 is provided between the vertical frames 4 without the gondola rail portion 12. The connecting member 14 may also be provided between the vertical frames 4 and 4 that do not include the frame 12. The connecting member 14 is made of, for example, an aluminum shape having a substantially transverse H-shape, and includes left and right flange portions 14a and 14a and a web portion 14b that connects both flange portions 14a and 14a. The connecting member 14 has a predetermined length, for example, about 150 mm.

  Grooves 15, 15 having a substantially U-shaped cross section are formed opposite to each other in the vertical frames 4, 4, and the flanges 14 a of the connecting members 14 are locked in the respective grooves 15 to restrain the pulling in the lateral direction. An engaging portion 16 is provided. Each groove portion 15 includes an engaging groove portion including the locking portion 16 and having a substantially C-shaped cross section. Further, a positioning member 17 for positioning and locking the connecting member 14 at a substantially central portion in the height direction between the vertical frames 4 and 4 is attached to the locking portion 16 with a fixing tool such as a screw 18. The connecting member 14 is dropped from above the vertical frame 4 so as to straddle both groove portions (engagement groove portions) 15 of the opposing vertical frames 4 and 4, and is positioned and locked on the positioning member 17. The connecting member 14 allows, for example, lateral compression (movement in a direction away from each other) and relative movement in the vertical direction other than the horizontal pull (movement in a direction away from each other) between the vertical frames 4 and 4 facing each other. . It is preferable that a slip agent 19 is coated on a portion of the connecting member 14 that contacts the groove 15.

  Between the opposing vertical frames 4 and 4, a rain barrier 20 for preventing rainwater from entering is provided outside the room, and a wind barrier 21 for preventing wind from entering the room inside. The wind barrier 21 is made of an airtight material made of rubber or soft resin, for example. In order to prevent the vertical frames 4 and 4 from being pushed open by this elastic force, as shown in FIG. 4, the vertical frames 4 are connected to each other between the vertical frames 4 where the connecting member 14 is not provided. For example, a joint member 22 made of an aluminum shape member is provided on the indoor side of the wind barrier 21 along the longitudinal direction thereof. In addition, if the connection member 14 is provided between the vertical frames 4 and 4 shown in FIG. 4, the joint member 22 will become unnecessary.

  According to the curtain wall 1 having the above configuration, the unit 7 having the frame 5 including the upper frame 2, the lower frame 3, the left and right vertical frames 4, 4 and the panel 6 provided in the frame 5 is The curtain wall 1 is disposed adjacent to each other in the vertical direction and the vertical direction, and a gondola rail portion 12 for guiding the guide roller 11 of the gondola 10 is provided on the opposing vertical frames 4 and 4 of the adjacent units 7. Since the connecting member 14 is provided at least in the central portion in the height direction between the frames 4 and 4 to restrain the horizontal frames 4 and 4 from pulling in the horizontal direction, the rigidity is improved, the design is improved, and the cost is reduced. I can plan.

  That is, since the opposing vertical frames 4 and 4 are connected to each other by the connecting member 14 that restrains the pulling in the horizontal direction, for example, a load or an external force due to the roll of the gondola 10 caused by an earthquake is applied to both the vertical frames 4 and 4. Thus, the rigidity of the vertical frame 4 can be improved, the seismic performance against the weight of the gondola 10 is improved, and the frame 5 of the unit 7 can be economically designed. In other words, the thickness of the vertical frame 4 can be reduced, the finding dimension can be reduced (slimmed), and the design can be improved and the cost can be reduced.

  Further, since both the vertical frames 4 and 4 are connected by the connecting member 14 so as to restrain the pulling in the horizontal direction, it is possible to prevent a gap from being generated in the wind barrier 21 provided between the both vertical frames 4 and 4. And watertight performance can be improved. In addition, a phenomenon (interlocking) that deforms into a bow shape so that the central portions in the height direction of the vertical frames 4 and 4 are separated by the elastic force (repulsive force) of the wind barrier 21 can be prevented. Since the connecting member 14 allows the vertical frames 4 and 4 to move relative to each other in the vertical direction (not constrained), the curtain wall 1 suitable for absorbability of thermal expansion and contraction, earthquake resistance, and the like is provided. Can do.

  Although the embodiments and examples of the present invention have been described in detail with reference to the drawings, the present invention is not limited to the above-described embodiments and examples, and various design changes can be made without departing from the gist of the present invention. Etc. are possible. For example, the shape of the connecting member may be U-shaped in addition to the H-shaped cross section, or a pair of enlarged portions 14a, 14a having a circular or elliptical cross section as shown in FIG. The shape which connected by the connection part 14b may be sufficient. In this case, the opposing vertical frames 4, 4 are provided with engaging groove portions 25 having a substantially C-shaped cross section for locking the enlarged portions 14 a along the longitudinal direction. Moreover, the connection member may be provided in the full length direction between the vertical frames.
