In modern wood construction, sills usually come in sizes of 2×4, 2×6, 2×8, and 2×10. In stick framing, the sill is made of treated lumber, and is anchored to the foundation wall, often with J-bolts, to keep the building from coming off the foundation during a severe storm or earthquake. Building codes require that the bottom of the sill ...
Wood cut from Victorian Eucalyptus regnans The harbor of Bellingham, Washington, filled with logs, 1972. Lumber is wood that has been processed into uniform and useful sizes (dimensional lumber), including beams and planks or boards. Lumber is mainly used for construction framing, as well as finishing (floors, wall panels, window frames ...
Poles, from which these buildings get their name, are natural shaped or round wooden timbers 4 to 12 inches (100 to 300 mm) in diameter. [4] The structural frame of a pole building is made of tree trunks, utility poles, engineered lumber or chemically pressure-treated squared timbers which may be buried in the ground or anchored to a concrete slab.
The invention of laminated veneer lumber as known today can be attributed to Arthur Troutner. While glue laminated wood veneers were in use since the middle of the 19th century on a small scale for furniture and pianos, Troutner was the first to develop a laminated veneer lumber of a scale large enough to be used in construction.
The Log Scaler measures the cut trees to determine the scale (volume) and quality (grade) of the wood to be used for manufacturing. When logs are sold, in order to determine the basis for a sale price in a standard way, the logs are "scaled" which means they are measured, identified as to species, and deductions for defects assigned to produce ...
Timber design or wood design is a subcategory of structural engineering that focuses on the engineering of wood structures. Timber is classified by tree species (e.g., southern pine, douglas fir, etc.) and its strength is graded using numerous coefficients that correspond to the number of knots, the moisture content, the temperature, the grain ...
[citation needed] PSL can be made from any wood species, but Douglas fir, southern pine, western hemlock, and yellow poplar are commonly chosen [9] because of their superior strength. The product is manufactured as a 12-by-12-inch (300 mm × 300 mm) or 12-by-18-inch (300 mm × 460 mm) billet in a rectangular cross-section, which is then ...
mudsill - a stud sized member that forms the base of a wall and has been treated against insects and decay. top plate or double top plate - a stud sized member that forms the top of the wall. In cases where other members must bear or brace on the top of the wall a double top plate is used with the member using offset laps so the top plate ...
