Abstract: A ply joint bar for casting a seamless ceiling from a hardening material such as plaster or concrete, poured over the surfaces of adjacent molding panels, has a bridge with a lower surface resting on and flush with two such adjacent panels and an upper gable-like portion adapted to be anchored in the hardened casting material, an optional base member with two adjacent coplanar surfaces which grasp the underside of the panels, and a leg frangibly connected at one of its ends to the bridge and permanently connected at its other end to the base member, so as to separate adjacent panels sandwiched between the bridge and base member. After the casting material hardens, the molding panels are removed and the frangible leg separated from the bridge leaving a substantially seamless ceiling surface with the bridge embedded therein and its lower surface flush therewith.

Abstract: A construction for a space frame system of the type wherein an upper chord frame and a lower chord frame structure are formed of a plurality of strut members connected to each other and held together by a plurality of connecting fixtures and web struts. The cord struts are of an improved form which adds to the structural strength of the space frame assembly. The struts are bent or otherwise formed into elongated channels which include a pair of outwardly and sidewardly projecting lip portions which are oriented in a plane substantially parallel to the channel bottom portion. The lip portions provide attachment surface portions which allow a great variety of mounting and support connections.

Abstract: Rolled or extruded box beams and rafters are supported from an existing wall or other structure with the aid of added posts. The beams and rafters extend trasversely to each other, the rafters being secured at the wall by an anchor fascia. A front fascia is fixed to the rafters and also defines a gutter. Roof panels on the rafters are joined along their edges. Each roof panel has a shaped cup edge and an opposite shaped hook edge. The hook of one panel fits into the cup of the adjoining panel. A fastening flange on each cup edge affords means for fixing the panels to the rafters.Preferably the visible bottoms and sides of the rafters and the beams are covered by decorative sheaths, each being an open channel with means for attachment to the rafters and beams. The beams and related rafters are configured to approximate the nominal sizes of conventional wooden structural members, and the exterior surfaces of the fascia, sheaths and anchor fascia are finished in a wood pattern.
