Prefab. support and locking attachments

摘要

The support elements may be slanting, single, double and rotationally symmetrical bar-shaped pieces. Lug-shaped (15,16,17,18) and cone-shaped (11,12) components interlock to form an angle of incidence as lugs and cones correspond to the static friction angle and transmit friction from one support element to another (1). The angle of incidence (13) is between 85 and 87 deg. This angle is equal to or less than the static friction angle.
