Deck 20: Wood and Metal Light Frame Construction

Question 1

Describe how wood foundations are made and used, and how they arrive at the site.

Answer 1

Wood foundations are sometimes used for buildings with basements or crawl spaces. The materials are stress graded to insure they can withstand lateral soil and subsurface water pressures. Wood materials must have the stamp of the American Wood Preservers Association (AWPA). Foundation panels are often shop-built and then shipped to site. The studs forming the panel face the inside of the building and are insulated in the same manner as an exterior above-grade wall.

Question 2

Explain how ceiling framing is mounted and used.

Answer 2

Ceiling joists are supported on exterior walls and load-bearing interior partitions. They carry the finish ceiling materials and insulation. If they are subject to other loads, such as a second floor storage area, the architect will size them accordingly. When they become joists for the second floor of a two-story building, their framing is identical to the framing of the first floor. The first ceiling joist is set in from the outer edge of the plate on the gable end to permit construction of the framing for the gable end wall. Ceiling joists can be trimmed to follow the rafter shape.
