X-6556 JOINT ASSEMBLIES BETWEEN STRUCTURAL MEMBERS Abstract of the Disclosure A joint assembly between structural members having plate portions includes an eliptical opening through the plate portion of a first member and a notched locking plate portion on a second member. The latter plate portion is in- troduced through the eliptical opening parallel to the major dimension thereof and is then rotated 90° to a locking position parallel to the minor dimension of the opening, whereby the notches interengage with the first plate portion to restrain separation of the two structural members. Resilient spring clips are mounted on the first plate portion outwardly adjacent the eliptical opening in the direction of the minor dimension thereof to releaseably engage the second plate portion against rotation when the latter is moved to the locking position. In another embodiment, a composite beam is assembled from a plurality of structural members having plate portions provided with eliptical openings therethrough. The structural members are interengaged with the plate portions in parallel juxtaposed relationship by means of a notched key plate introduced through the openings and rotated relative thereto in the foregoing manner for interengagement with spring fingers on one of the members.
