Conlilevered Floor Booklet

Timber Engineeting Company (Teco) ha3 announced a descriptive folder on its Linei A-Joi.st connector firr cantilevered flooi constluction. Replesenting a new concepf in the framing of floor joists, the Teco system can save as much as $30 per housd through more elliciettt utilization of lumber. Comprehensive design tables prepared by theit engineels show that in most cases it is possible to use floor joists 2" less in depth when utilizing the Line-A-Joist system of construction. 'l'his is accomplished by taking full advantage of the combined negative and positive bending etrect tha! results from the cantileveling of joists. Unlike conventional framing, where ond

joist butts or laps another over a central support, the Teco system calls for one joist to cantilever over the support a predetermined dimension where it is joined to a shorter joist (called the supported joist) with the Line-A-Joist connector.

Manufactured of 16 gauge, galvanized sheet steel, the Line-A-Joist connector is designed to transmit shear loads from the cantilevered joist to the supported joist. The product is available in three sizes to accommodate 2x6,2x8,2x10 and 2xL2 members. Special l\/2" length, hardenefl steel, spiral shank nails are r'ncluded in each carton of connectors.

New Sheothing Product

United States Plywood has developed a new weather-proof plywood sheathing, L-lR-X, "to meet the needs of plemium housing," vice president M. W. Pollack has announced.

"This new sheathing is a successor to our Weldwood L-1R grade, an earlier product featuring a moll-resistant glue," Mr. Pollack said. "L-lR-X, at a slight premium over existing sheathing grades, has proved superior to L-1R in lesistance to adverse exterior effects such as water and mold and has proved immune to delamination despite severe storage and installation conditions."

L-1R-X, using new resin knowledge, features an exterior glue throughout. Based on lengthy laboratory and field tests, L-IR-X carries a performance guarantee against delamination for one year, if stored off the ground; and for the life of the installation if used indoors and not in contact with the ground.

L-1R-X will meet the glue line requirements of the strictest building codes, Mr. Pollack said. Edges are treated with Convoy, a new weather and fungi-resistant treatment that was developed recently by Protection Products division of U.S. Ply- wood. This water-repellent emulsion will act also as a color coding system for the new sheathing product.

Production of L-IR-X began in January and is now becoming available at U.S. Plywood's 133 branches and warehouses thloughout the U.S.
