Observe the following guidelines:1.2.3.4.5.6.Properly install all blocking, hangers, rim boards, and rim joists at TJI joist end supports.E stablish a permanent deck (sheathing), fastened to the first 4 feet of joists at the end of the bay or braced end wall.Safety bracing of 1x4 (minimum) must be nailed to a braced end wall or sheathed area and to each joist.Sheathing must be completely attached to each TJI joist before additional loads can be placed on the system.Ends of cantilevers require safety bracing on both the top and bottom flanges.The flanges must remain straight within ½" from true alignment.This guide is intended for the products shown in dry-use conditions.La Sécurité Avant ToutLa Seguridad Ante TodoLire AttentivementPor Favor Lea CuidadosamenteAVERTISSEMENT Les solives non contreventées latéralement sont instables. Voir le guided’installation avant la pose des solives TJI . Ne pas circuler sur les solives TJI avant qu’elles ne soient adéquatementcontreventées. Risque de blessure. Ne pas empilées des matériaux sur des solives avant d’avoir installé les sousplancher. Les entreposer temporairement au-dessus des poutres et murs.ADVERTENCIA L as viguetas son inestables hasta que sean reforzadas lateralmente.Vea la guía de instalaciones antes de instalar las viguetas TJI . No camine sobre las viguetas hasta que sean apuntaladas. No ponga materiales de construcción sobre las viguetas TJI antes deinstalar el triplay. Ponga materials únicamente sobre vigas o muros.

Fully nail floor panel within 10 minutes of applying adhesive(or sooner if required by adhesive manufacturer).

Squash blocks and blocking panels carry stacked vertical loads(details B1 and B2). Packing out the web of a TJI joist (with webstiffeners) is not a substitute for squash blocks or blocking panels. When joists are doubled at non-load bearing parallel partitions,space joists apart the width of the wall for plumbing or HVAC. Additional joist at plumbing drop (see detail at right).Joist may be shifted upto 3" if floor panel edgeis supported and spanrating is not exceeded.Do not cut joist flanges.Additional joist isrequired if floor paneledge is unsupportedor if span rating isexceeded.
