Japanese Unexamined Patent Publication No. 2000-54649

By the way, a wall panel may be movably fixed to a beam or a pillar of a building for the purpose of suppressing the occurrence of cracks in the outer wall due to shaking such as an earthquake. In this case, when the building shakes, the exterior panel of the outer wall may be deformed and cracks may occur. Therefore, an outer wall and a building capable of suppressing deformation or cracking of the exterior panel are provided.

(1) The outer wall for solving the above problems is via a plurality of wall panels movably fixed to the frame, a furring strip provided on the wall panel so as not to straddle the plurality of wall panels, and the furring strip. With at least one exterior panel attached to the wall panel, at least one of the exterior panels is secured to one of the plurality of wall panels via the furring strip.

According to this configuration, the furring strip is provided on the wall panel so as not to straddle the plurality of wall panels, so that the wall panel is not constrained to the adjacent wall panel. Further, the exterior panel is provided on one wall panel via the furring strip. Therefore, when the building shakes, the exterior panel can be moved to follow the wall panel. When the exterior panel is fixed to two wall panels, when the building shakes, stress of pulling, pressing and twisting is applied to the exterior panel, and such stress is suppressed. In this way, deformation or cracking of the exterior panel can be suppressed.

The movement of the exterior panel includes the movement of the exterior panel up and down, left and right, and back and forth, as well as the vibration and rotation of the exterior panel. The movement of the wall panel is the same, and includes the movement of the wall panel up / down, left / right, back and forth, as well as the vibration and rotation of the wall panel. Further, the movement of the protruding corner member, which will be described later, is the same, and includes the movement of the protruding corner member up / down, left / right, and front / back, as well as the vibration and rotation of the protruding corner member.

(2) In the outer wall of the above (1), a protruding corner member arranged at the protruding corner of the building is further provided, and one of the two exterior panels in contact with the protruding corner member is attached to the protruding corner member. It is fixed and the other exterior panel is movable with respect to the protruding corner member.

When two exterior panels are fixed to the projected corner member, the projected corner member and the two exterior panels sway in the same direction at the same time due to the shaking of the building caused by an earthquake or the like, and as a result, at least one of the two exterior panels is a wall. It becomes easier to hit the panel, and at least one of the two exterior panels may be deformed or cracked. In this respect, in the case of the above configuration, since one exterior panel is fixed to the projected corner member and the other exterior panels are movable with respect to the projected corner member, the projected corner member and the two exterior panels are separated. At the same time, it becomes possible to suppress shaking in the same direction, making it difficult for the exterior panel to hit the wall panel. In this way, deformation or cracking of the exterior panel can be suppressed.

(3) Of the two exterior panels that come into contact with the projected corner member on the outer wall of the above (2), the exterior panel fixed to the projected corner member is movable with respect to the wall panel.
When the projected corner member and the wall panel are connected via the exterior panel and the projected corner member and the wall panel are restrained from each other, the projected corner member, the wall panel, and the wall panel are swayed in the shaking of the building caused by an earthquake or the like. Stress may be applied to any of the exterior panels, causing the exterior panels to deform or crack. In this respect, the protruding corner member and the wall panel can move independently, and the exterior panel moves following the protruding corner member, so that the force applied to the exterior panel is suppressed. In this way, deformation or cracking of the exterior panel can be suppressed.

(4) In any one of the above (1) to (3), a cover provided so as to extend over the plurality of the wall panels and the plurality of exterior panels and covers the upper end or the lower end of the plurality of exterior panels is further covered.

When the cover provided so as to cover the plurality of wall panels is fixed to each of the wall panels at a plurality of places, the cover may be deformed in a wavy manner due to the shaking of the building caused by an earthquake or the like. In this respect, since the wall panel is easy to move with respect to the cover, the cover is suppressed from being deformed in a wavy manner.

(5) In the outer wall of the above (4), the cover is fixed to the central portion of the upper end or the lower end of each of the wall panels by a locking member. In the shaking of a building caused by an earthquake or the like, the amount of movement is large at both ends of the lower end of the wall panel in the lateral direction or at both ends of the upper end in the lateral direction. When the end of the cover is fixed to the lateral end of the top edge of the wall panel or the lateral edge of the bottom edge, the cover is susceptible to deformation. In this respect, according to the above configuration, since the cover is fixed to the central portion of the upper end or the lower end of each wall panel by the locking member, the deformation of the cover is suppressed.

(6) In the outer wall of the above (5), when the end portion of the cover is arranged in the inner corner, the end portion of the cover is arranged in the central portion of the wall panel constituting the inner corner, and the wall panel. The portion of the wall panel that is fixed to the central portion of the inside and constitutes the inside corner and is not covered by the cover is covered with an additional cover.
