Abstract
In a column structure (10), a steel column (38) having a web (38A) and flanges (38B) integrally provided to both sides in a width direction of the web (38A) is welded to a base plate (16). First anchor bolts (24) and second anchor bolts (26) are anchored in foundation concrete (12). The base plate (16) is fixed to the first anchor bolts (24) at an opposite side to the web (38A) with respect to the flanges (38B), and fixed to the second anchor bolts (26) at a web (38A) side with respect to the flanges (38B). The load bearing ability of a column setup can therefore be efficiently exhibited, and a thickness dimension of the base plate (16) can be reduced.

A column structure comprising:
- a column member having a web and flanges that are integrally provided at both sides, in a width direction, of the web;
- a base member having an upper side that is joined to the column member;
- a first anchor member including a lower end side and an upper end side, a first anchor portion is attached to the lower end side and the lower end side is anchored in concrete, and the base member is fixed to the upper end side at an opposite side to the web with respect to the flange;
- and
- a second anchor member including a lower end side and an upper end side, a second anchor portion is attached to the lower end side and the lower end side is anchored in concrete, and the base member is fixed to the upper end side at a web side with respect to the flange.
A base member that is configured to join to a column member having a web and flanges that are integrally provided at both sides in a width direction of the web, the base member comprising:
- a base body that has an upper side for joining to the column member;
- a first fixing portion provided at the base body at an opposite side to the web with respect to the flange, and the first fixing portion is fixed to an upper end side of a first anchor member, the first anchor member includes a lower end side to which a first anchor portion is attached and the lower end side is anchored in concrete;
- and
- a second fixing portion provided at the base body at a web side with respect to the flange, the second fixing portion is fixed to an upper end side of a second anchor member, the second anchor member includes a lower end side to which a second anchor portion is attached and the lower end side is anchored in the concrete.
