Abstract
In a column structure, a steel column having a web and flanges integrally provided to both sides in a width direction of the web is welded to a base plate. First anchor bolts and second anchor bolts are anchored in foundation concrete. The base plate is fixed to the first anchor bolts at an opposite side to the web with respect to the flanges, and fixed to the second anchor bolts at a web side with respect to the flanges. The load bearing ability of a column setup can therefore be efficiently exhibited, and a thickness dimension of the base plate can be reduced.
Claims11
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, wherein an indented portion is provided in a lower side face of the base member;
- a first anchor member including a lower end side and an upper end side, wherein 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 of the first anchor member at a position of the base member that is at an opposite side of a flange of the column member from a side of the flange at which the web is located;
- and
- a second anchor member including a lower end side and an upper end side, wherein 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 extends on a single plane and that has an upper side for joining to the column member, wherein an indented portion is provided in a lower side face of the base body;
- a first fixing portion provided at the base body at an opposite side to the web with respect to a flange of the column member, wherein 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, wherein 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,
- wherein a plurality of first fixing portions are disposed at a left hand side portion and a right hand side portion of the base body and a plurality of second fixing portions are disposed at inner side portions from locations where the first fixing portions are disposed.
