Steel studs are gaining popularity as a non-combustible alternative, especially for non load-bearing walls, and are required in some firewalls. In New Zealand, the required lumber size and spacing of wall studs are determined using NZS 3604 Timber-framed buildings table 8.2 for loadbearing walls and table 8.4 for non-loadbearing walls. [4]
Earthing systems. v. t. e. Knob-and-tube wiring (sometimes abbreviated K&T) is an early standardized method of electrical wiring in buildings, in common use in North America from about 1880 to the 1930s. [1][2] It consisted of single-insulated copper conductors run within wall or ceiling cavities, passing through joist and stud drill-holes via ...
Dwang. In construction, a dwang Scotland and New Zealand, [1] [2][3] nogging piece, nogging, noggin or nog (all derived from brick nog) [4][5] England and Australia, or blocking North America, is a horizontal bracing piece used between wall studs to give rigidity to the wall frames of a building. Noggings may be made of timber, steel, or ...
Exterior wall studs are the vertical members to which the wall sheathing and cladding are attached. [14] They are supported on a bottom plate or foundation sill and in turn support the top plate. Studs usually consist of 1 + 1 ⁄ 2 -by- 3 + 1 ⁄ 2 -inch (38 mm × 89 mm) or 1 + 1 ⁄ 2 -by- 5 + 1 ⁄ 2 -inch (38 mm × 140 mm) lumber and are ...
Lumber. 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).
A load-bearing wall or bearing wall is a wall that is an active structural element of a building, which holds the weight of the elements above it, by conducting its weight to a foundation structure below it. Load -bearing walls are one of the earliest forms of construction. The development of the flying buttress in Gothic architecture allowed ...
From the early 1960s, high-tensile 12½ gauge (2.5 mm) steel wire has largely replaced number 8 wire for New Zealand fencing, as it is lighter and cheaper, though also more difficult to work. [4] Since 1976, when New Zealand adopted the metric system , number 8 wire is officially referred to as 4.0 mm gauge wire, although the older term "Number ...
An engineered wood joist, more commonly known as an I-joist, is a product designed to eliminate problems that occur with conventional wood joists. Invented in 1969, the I-joist is an engineered wood product that has great strength in relation to its size and weight. The biggest notable difference from dimensional lumber is that the I-joist ...
