SUPPORT STRUCTURE OF CURTAIN WALL

摘要

PROBLEM TO BE SOLVED: To easily adjust the position of a curtain wall and avoid a large force acting on a dead-weight receive bolt when a lateral load acts by providing a cap member to reduce a frictional coefficient between a dead weight receive bolt and a support member at the head of the bolt. SOLUTION: A support structure 10 is provided with an insert 3 embedded in a protruded part 2b formed in the inside wall face 2a of a curtain wall 2 and a dead weight receive bolt 11 screwed in the insert 3. The front end part 11a of the dead weight receive bolt 11 is screwed in a female screw in the insert and the head 11b is projected downward from the protruded part 2b of the curtain wall 2 and brought into contact with a support member 5 fixed to a structure equipped with the curtain wall 2 from above through the cap member 12. The contact area on the support member 5 can be reduced and the frictional coefficient between them can be reduced by the cap member 12 provided in the head 11b of the dead weight receive bolt 11.
