One column receives a compressive force and the other column receives a pull-out force. When the force between the upper and lower column members 25 and 26 exceeds the yield point of the deformable member 32 in the column on the side where the pulling force is applied, the deformable member 32 plastically deforms and expands in the height direction, as shown in FIG.

This mechanism can be generalized to connect the upper and lower column members 25 and 26 via a viscoelastic member, release the pull-out force by extending the viscoelastic member in the height direction, and improve the earthquake resistance. Therefore, the deformable member can be replaced with an elastic member such as a spring or rubber, a damper such as an oil damper or an oil film damper, a gel-like substance, or another viscous substance. Hereinafter, a damper using a fluid such as an oil damper or an oil film damper will be simply referred to as a damper. Also, the mild steel itself used for the deformable member can be regarded as a kind of viscous member. In this way, the meaning of the deformable member is generalized, and the second to sixth

The upper end of the elastic body 48 is supported by the attachment 41 connected to the lower column member 26, and the lower end of the elastic body 48 is supported by the attachment 42 connected to the upper column member 25. . The fact that the upper column member 25 is shifted in the horizontal direction is as follows.
This can be prevented by the attachments 41 and 42 and the support plate 43. When a pulling force is applied to the upper column member 25 at the time of an earthquake or the like, the fitting 42 relatively rises, and the elastic body 48 is compressed. Since the elastic body 48 is pulled by the pulling force, there is no possibility that the elastic body 48 is damaged. In the embodiment of FIG. 4, a viscous body or a damper may be used instead of the elastic body 48.

Such an embodiment is shown in FIG. Reference numeral 60 denotes an outer cylinder, and 61 denotes a viscoelastic body, which uses a highly elastic or highly viscous fluid such as an adhesive or asphalt. Normally, the column member 26 and the column member 25 are connected to the outer cylinder 60 via the viscoelastic body 61. In addition, since the outer cylinder 60 is provided, the column member 2
No horizontal movement between 5 and 26 occurs. When a pulling force acts on the upper column member 25 from this state, the viscoelastic body 61 acts as a kind of damper, and allows the column member 25 to move upward while applying friction. The advantages of the embodiment of FIG.
Since only the outer cylinder 60 and the viscoelastic body 61 are used, the dead space is small, and after the earthquake or the like, the upper column member 25 may drop by its own weight and return to the state before the earthquake.
