Flexible joint building system

A dynamic eave assembly for coupling structural members in an angulated relationship one to the other and allowing flexibility therebetween for dynamic and static loading thereupon, said structure comprising means associated with said angulated members facilitating pivotal interaction therebetween, means for establishing a notional plane of intersection between said angulated members and a predefined space therebetween to accommodate said pivotal action during dynamic loading across said eave said means coupling said structural members comprising a pivot pin secured to one of said members and means associated with the other said members for engaging said pin and affording pivotal movement therearound, said structural members comprising a pivot, a first vertical mullion and a second mullion disposed at an angle relative thereto, said vertical mullion further including a pivot arm secured thereto having a journal formed therethrough and adapted for receipt of said pin therein, said second mullion having a knee splice secured thereto, said knee splice having apertures formed through the side walls thereof adapted for receiving said pin therethrough for facilitating pivotal motion about said journal, and said mullions each being hollow and further including means disposed in a lower region of said first hollow mullion adapted for sealably retaining water thereabove received from said second hollow mullion and means disposed adjacent said sealing means for discharging said water received therein.

A flexible structural joint comprising:

• a first mullion adapted for generally vertical positioning in the construction of a wall;
• a second mullion adapted for generally angulated positioning relative to said first mullion, said first and second mullions intersecting one another in an angulated relationship across a notional plane defined therebetween;
• means coupling said first and second mullions one to the other pivotal relationship therebetween;
• means for defining and maintaining a space along said notional plane of intersection between said first and second mullions to facilitate relative movement therebetween and flexibility of said mullions one to the other;
• said means coupling said first and second mullions comprising a pivot pin secured in one of said mullions and means associated with the other of said mullions for engaging said pin and affording pivotal movement therearound, and
• one of said mullions including a pivot arm secured thereto having a journal formed therethrough and adapted for receipt of said pin therein, said second mullion including a knee splice secured thereto, said knee splice having aligned apertures formed through the side walls thereof adapted for receiving said pin therethrough and facilitating pivotal motion about said journal.
