General Requirements Random Length Continuous (RLC) is the most common method of applying Lock- Deck. It allows the use of mixed lengths of material on a variety of span conditions, providing high structural efficiency and attractive appearance. The allowable RLC roof loads recommended in the span table are based on actual full-scale tests, where the decking was laid in conformance with certain rules. Install as follows for equivalent performance.
Diaphragm Construction Lock-Deck can be engineered to carry diaphragm shear forces from earthquake and high-wind forces. The most used method for obtaining diaphragm resistance is to install plywood or OSB over the Lock-Deck. The nailing of panel edges is the same as for panels installed over joists. The Lock-Deck provides the required blocking. Lock-Deck laminated roof or floor decking in 3", 4", and 5" thicknesses may be designed to resist lateral forces when a 3/8" bead of 3M adhesive No. 5200 is applied on top of the tongue-and-groove joint between adjacent decking courses. Random applied decking may be used and the nailing schedule is the same as regular deck. Either diaphragm design must have a continuous Chord along all sides to resist the moment forces. Nailing Schedule Toenailing along Courses:
Face Nailing to Supports:
Screws
Screws can be used as an alternate
providing equal shear and withdrawal
resistance are provided.
