The Roxy Theatre in St. Ansgar, Iowa, illustrates the advantages obtained in the use of a laminated arched framing member which gives continuous framing from the building foundation to the ridge of the roof. The Rilco Type 54 rafter employed completely eliminates the normal joint between the roof and the sidewalls; the walls and roof are, in fact, integrated by this arch into a single structural unit of great strength.

Rilco Type 54 rafters were delivered to the job location shaped, cut, drilled and ready for quick and easy erection. Spaced two feet apart and covered with one-inch decking, these rafters made the use of roof joists superfluous. Special metal angles, bolts and metal connectors anchored the rafters to the foundation and these members were joined at the ridge pole with metal ridge plates and bolts. Giving a clear span up to 70 feet, the Type 54 rafter was an ideal construction unit for the Roxy Theatre.


What is probably a still larger field for laminated wood structurals in theatre construction is that provided by theatre buildings with the conventional vertical walls and flat ceiling. The attractive new Walworth Theatre, Walworth, Wisconsin, demonstrates the application of a laminated unit to this type of building.

The Rilco Type 70 truss was utilized since it provides for clear span construction of theatres up to 60 feet wide. Delivered pre-cut and drilled, ready for easy assembly and fast erection, this truss eliminates the need for roof and ceiling joists since the roof sheathing is nailed directly to the arched members of the truss and the ceiling is applied to the underlying horizontal members. The strength-to-weight ratio of the truss is unusually high, and although it is light, it has great bearing qualities.

Requirements for clear spans up to

100 feet are met efficiently and economically by the Type 62 Bowstring Truss.


Another example of theatre construction with the Rilco Type 54 arched rafter is provided by the new Kce Theatre in Kicster, Minnesota. In this theatre, Nu-Wood sheathing over the arch of the rafter produces an interior effect of unusual distinction. The beautiful Gothic arch of the interior formed by the Type 54 rafter is highly practical in theatre construction because of the excellent acoustical qualities inherent in an auditorium built on pa cabolic lines.

For theatres larger than the Koo, the Type 59 arched rafter, similar in design to the Type 54, is specified. Type 59 is a heavier and stronger rafter, and its use calls for eight-foot spacing and twoinch decking.
