Anchor chair

Abstract

An anchor chair is configured for transmitting a pulling force from an elongated foundation element to a wall. The anchor chair includes a passage for the elongated foundation element, and a cavity between a first opening located on a first side of the anchor chair, which first side is facing away from the wall in attached state, and a second opening located on an opposite side of the anchor chair, which opposite side is facing the wall in attached state and which opposite side defines in attached state a contact area of the anchor chair to contact the wall. The first opening is a slot-shaped opening having two long sides and two short sides. In an attached state, the long sides of the slot-shaped opening of the anchor chair are oriented parallel to a plane perpendicular to the wall.
