Abstract
A structural system is comprised of two components. The first component is an I-shaped bearing member having an upper flange and a lower flange connected by a web. The upper and lower flanges have undercuts formed therein. The second component is a connection member having a notch in each corner for engaging the undercuts in the upper and lower flanges. The components of this system may be used to construct a structural component comprising a plurality of I-shaped bearing members positioned parallel to one another. A plurality of connection members interconnect the bearing members; the two upper notches of the connection member engage the undercuts in the upper flanges of two adjacent bearing members while the two lower notches engage the undercuts in the lower flanges of two adjacent bearing members. A method of constructing a structural component is comprised of positioning a plurality of bearing members parallel to one another. A plurality of connection members having cam surfaces are inserted between adjacent bearing members. Each connection member is rotated to first bring the cam surface into contact with the adjacent bearing members and then to lock the connection member in …
