Column cap and suspension column structure center pillar

摘要

PROBLEM TO BE SOLVED: To provide a column head and column base structure of an axial column capable of preventing generation of cracks and/or collapses in a column head part and a column base part of an axial column and a connection part thereof when a building is deformed in a horizontal direction.SOLUTION: An axial column 10 has a column head part 20 and a column base part 30 the diameters of which decrease toward the front end thereof. A horizontal movement prevention rod 90 is disposed between a horizontal member 50 and the column head part 20 and between the horizontal member 50 and the column base part 30; and the column head part 20 and the column base part 30 are connected to the horizontal member 50 respectively. The horizontal member 50 is provided with a concave 60 for inserting the column head part 20 or the column base part 30 thereinto, and between the inner face of the concave 60 and the outer peripheral face of the column head part 20 and the column base part 30, an elastic member 100 is disposed. The horizontal movement prevention rod 90 is preferably set to be free from fixation to at least one of the column head part 20 and the column base part 30 and the horizontal member 50.SELECTED DRAWING: Figure 1
