Description

  The present invention relates to a support column and a support method, and more particularly to a support column and a support method for supporting protruding portions such as a lower house, a fence, and a small roof provided in a state of protruding sideways from a base-isolated building.

  In general, projecting parts such as huts, fences, and small roofs that protrude sideways from the base-isolated building are connected to the base-isolated building with a predetermined slope and the tip is perpendicular to the ground. It is supported by upright posts.

  The projecting part with such a configuration is displaced following the base isolation building when the base isolation building is displaced by the input of external force such as wind or earthquake, so that an excessive load is applied to the column supporting the projecting part. There is a risk that the column will be bent or damaged.

For this reason, the projecting part is connected to the base-isolated building via an expansion joint, the projecting part is made independent from the base-isolated building, and the upper and lower ends of the column supporting the projecting part are pin-coupled. (For example, refer to Patent Document 1).
JP 2001-140337 A

  However, the method of using the expansion joint is not very attractive because the expansion joint is very expensive and the metal expansion joint is exposed. In addition, the method of pin connection between the upper and lower ends of the support column is that if the length of the support column is short, if the displacement in the horizontal direction is large, the vertical displacement is small, but the support column is bent or damaged. There is a risk of doing. Furthermore, the method of making the protruding portion independent from the base-isolated building increases the number of columns for supporting the protruding portion, and therefore cannot effectively use the space below the protruding portion.

  The present invention has been made in view of the conventional problems as described above, and does not increase cost, looks good, and even if the length of the support is short, it may be bent or damaged. It is an object of the present invention to provide a support and a support method that can effectively use the space below the protruding portion.
