  Hereinafter, embodiments of the exterior material of the present invention will be described in detail based on the drawings.

[First Embodiment]
(Composition of curtain wall 3)
FIG. 1 is a diagram showing an outline of a structure 10 provided with a curtain wall 3 as an exterior material according to the first embodiment of the present invention. As shown in the figure, the curtain wall 3 of the present embodiment is provided on the outer surface of the structure 10 separately from the structural housing of the structure 10 and does not directly bear the load of the structure 10. As will be described later, the curtain wall 3 has a vibration control function.

  Next, the curtain wall 3 will be described with reference to FIGS. FIG. 2 is an elevation view showing a part of the curtain wall 3 and shows a range a in FIG. 3 is a cross-sectional view taken along line AA in FIG. 4 is a cross-sectional view taken along line BB in FIG. 3, and FIG. 5 is a cross-sectional view taken along line CC in FIG.

  As shown in FIG. 2, in the curtain wall 3, a plurality of column portions 20 are provided in the horizontal direction in each layer. Each column part 20 consists of the column material 25, the horizontal material 11, and the joint part 21 which connects these.

  The horizontal member 11 is provided so as to extend from the upper part of the column member 25 to both sides in the horizontal direction. As shown in FIG. 3, the horizontal member 11 is connected to the structural housing 1 side of the column member 25 by a joint portion 21. In this embodiment, H-shaped steel is used as the column member 25 and the horizontal member 11, but the present invention is not limited to this. Members of various shapes and materials can be used depending on the purpose. However, when H-shaped steel is used for the column member 25 as in this embodiment, there is an advantage that the flange portion functions as a vertical rod and a solar radiation shielding effect is obtained.

  The ends of the horizontal members 11, 11 of the adjacent column portions 20, 20 are connected to each other by the damping material 13 at the connecting portion 30. That is, both ends of the damping material 13 are joined to the end portions of the horizontal members 11 and 11, respectively.

  The damping material 13 yields when a force is applied during an earthquake or the like, and at that time obtains a damping force to exhibit a damping function, and is a steel honeycomb damper, for example. However, the damping material 13 is not limited to this, and other steel dampers may be used, or any damping material 13 can be used as long as damping force can be obtained, such as a viscous damper such as a hydraulic damper. is there.

  In addition, as shown in FIG. 3, the column portion 20 is provided with an overhang portion 9 that protrudes toward the structure housing 1 (inner structure housing) side of the structure 10 at the joint portion 21. The casing 1 is rigidly connected using bolts or the like.

  Glass 17 is disposed between the column members 25 and 25 of the adjacent column portions 20 and 20. The periphery of the glass 17 is held by a frame 15. The frame 15 is attached to the column portion 20 or the like using an attachment jig (not shown) or the like.

  The frame 15 holds the glass 17 in a slidable manner, and has a space 41 for allowing the glass 17 to move slightly in width as shown in FIG. Therefore, as will be described later, even when the curtain wall 3 is locked and deformed, almost no stress is transmitted to the glass 17.

  The curtain wall 3 is configured by vertically arranging the layers configured as described above. At this time, as shown in FIG. 4, the lower pillar portion 20 and the upper pillar portion 20 are connected at a pin connection portion 53.

As shown in FIGS. 4 and 5, two cylindrical pins 27 are fixed on the plane on the joint portion 21 of the lower column portion 20. The pin 27 is provided in the vertical direction and penetrates through a plate 38 provided at the upper end of the lower column member 25 and protrudes upward.
On the other hand, a plate 37 is provided at the lower end of the upper column member 25. The plate 37 is provided with two circular holes 36 having a diameter slightly larger than that of the pin 27.

  In the pin connection portion 53, the upper layer column portion 20 is disposed on the lower column portion 20 while passing the pins 27 through the two holes 36 of the plate 37 at the lower end portion of the column member 25. Thereby, the column parts 20 and 20 of the upper and lower layers are connected. The curtain wall 3 can be assembled in order from the lower layer while connecting the upper column 20 to the lower column 20 in this manner.

  In this embodiment, with such a configuration, the pin connection portion 53 has a lower rigidity with respect to rotation in the vertical plane of the column portion 20 and a higher rigidity with respect to rotation in the horizontal plane.

  That is, in the pin connection portion 53, the upper layer column portion 20 is connected by placing the lower pin 27 through the hole 36 of the plate 37, and the lower end portion of the column portion 20 is movable along the pin 27. . At this time, according to the horizontal force applied to the curtain wall 3, as shown in FIG. 6, the column portion 20 can move while being slightly rotated and inclined, and the rigidity against rotation in the vertical plane is low. On the other hand, since a plurality of pins 27 are provided on the plane, the column portion 20 is prevented from rotating in the horizontal plane, and has a structure with high rigidity against rotation in the horizontal plane.

  As shown in FIG. 4, a spacing member 39 is disposed between the plates 37 and 38, and there is a slight gap between the upper end of the lower column member 25 and the lower end of the upper column member 25. There is an interval. This interval is sealed with a sealing material 47.

(Vibration control by curtain wall 3)
Next, the vibration control action of the curtain wall 3 during an earthquake will be described with reference to FIG. FIG. 7 is a diagram schematically showing a deformed state of the curtain wall 3 during an earthquake or the like. In the figure, a part of one layer of the curtain wall 3 is shown, and the deformed state is slightly exaggerated for explanation.

  As shown in the figure, when the structure 10 having the curtain wall 3 receives a horizontal force as indicated by an arrow H, the curtain wall 3 locks following the interlayer displacement of the structure 10 and is indicated by an arrow I. Rotate in the vertical plane. In the curtain wall 3, a force is applied to the damping member 13 so that the end of the horizontal member 11 is displaced in the connecting portion 30 with this deformation. The damping material 13 is deformed by this force and yields, and a damping force is obtained at this time. Therefore, the horizontal force input to the structural housing 1 of the structure 10 can be reduced, and the seismic performance of the structure 10 is ensured.

  At this time, the pin connection portion 53 has low rigidity against rotation in the vertical plane of the column portion 20 as described above, so that the column portion 20 is easy to rotate, and the deformation of the damping material 13 accompanying rocking can be increased, so that a larger damping force can get.

  As described above, according to the present embodiment, when the curtain wall 3 locks following the interlayer displacement of the structure 10, a damping force is obtained by the damping material 13 of the coupling portion 30 between the column portions 20. , Can exert seismic control function. Thus, in this embodiment, since the damping material 13 is built in the curtain wall 3, while improving the earthquake resistance of the structure 10, a wide space can be secured inside and the freedom degree in design can also be raised. Further, in the repair of the existing structure 10, since the work is mainly performed from the outside of the living room, the construction is easy and the maintenance can be improved.

  Moreover, since the column part 20 can rotate within a vertical plane, the damping material 13 can be greatly deformed during locking to obtain a larger damping force. Moreover, in this embodiment, since this is implement | achieved by the simple structure by the pin connection part 53 using the some pin 27, construction becomes easy. Furthermore, it is possible to reliably obtain a damping effect by preventing the rotation of the column part 20 in the horizontal plane and preventing the curtain wall 3 from being deformed out of plane.

  However, the present invention is not limited to this. Hereinafter, another example will be described as the second and third embodiments. The following embodiment will mainly describe differences from the first embodiment, and description of similar points will be omitted.

[Second Embodiment]
In the first embodiment, the curtain wall 3 is connected to the structural housing 1 using a bolt or the like, but the connection method is not limited to this. The second embodiment is an example thereof, and FIG. 8 is a diagram illustrating a connection portion between the curtain wall 3a and the structural housing 1 of the second embodiment.

  As shown in FIG. 8, in the second embodiment, the curtain wall 3 a and the structural casing 1 are connected by inserting a cylindrical pipe 28 provided in the structural casing 1 into the joint portion 21, and this connection location The column 20 is also rotatable in the vertical plane. In addition, in this connection location, the movement of the column part 20 is restrained about another direction.

  Even in this case, the same effect as the first embodiment can be obtained. Furthermore, in the second embodiment, the column part 20 is more easily rotated in the vertical plane, and the damping effect by the damping material 13 can be increased.

[Third Embodiment]
In the first embodiment, the column part 20 is connected by the pin connection part 53, but this may be omitted depending on circumstances. The third embodiment is an example thereof, and FIG. 9 is a diagram illustrating the vibration control function of the curtain wall 3b of the third embodiment.

  As shown in the figure, in the pillar portion 20a of the curtain wall 3b of the present embodiment, the length of the pillar material 25a for one layer is long and the rigidity of the pillar itself is low, so that it deforms during an earthquake and rotates in a vertical plane. It is possible. As described above, if deformation and rotation of the column itself can be expected, a desired attenuation effect can be exhibited without necessarily providing the pin connection portion as described above, and the same effect as in the first embodiment may be obtained. .

  Thus, the configuration of the curtain wall can be variously considered as long as the damping material 13 is provided between the adjacent column portions 20. What kind of configuration should be determined according to the target damping performance and workability.

  In the above description, the damping material 13 is provided in each layer. However, the present invention is not limited to this, and the location where the damping material 13 is provided can be determined according to the purpose. For example, the damping material 13 may be provided every other layer. Further, the damping material 13 may not be provided at all between the pillar portions of each layer, and may be provided only at a part. Furthermore, it is also possible to form a curtain wall by combining the configurations of the first to third embodiments. Further, the curtain wall is not limited to being provided on only one surface of the structure 10 as shown in FIG. 1, and can be appropriately provided on each surface of the structure 10.

  Furthermore, the exterior material of the present invention is not limited to the curtain wall as described above. For example, a mechanism in which the glass 17 or the like is omitted outside the structure 10 and the damping material 13 is provided between the adjacent column portions 20 as described above is also considered as an exterior material, for example, when used for seismic retrofit.

  As mentioned above, although embodiment of this invention was described referring an accompanying drawing, the technical scope of this invention is not influenced by embodiment mentioned above. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the technical idea described in the claims, and these are naturally within the technical scope of the present invention. It is understood that it belongs.
