Furring
In construction, furring (furring strips) are strips of wood or other material applied to a structure to level or raise the surface, to prevent dampness, to make space for insulation, to level and resurface ceilings or walls, or to increase the beam of a wooden ship. Furring refers to the process of installing the strips and to the strips themselves. ''Firring'' is a U.K. term for wood strips which are usually 50 mm wide, tapered and fixed above wood roof joists to provide drainage falls below roof boarding. Furring strips themselves are typically referred to as ''battens'' in the U.K. and sometimes the material is called ''strapping'' in the U.S. In buildings Wood furring strips typically measure 1 x 2 or 1 x 3 inches. They can be laid out perpendicular to studs or joists and nailed to them, or set vertically against an existing wall surface. The spacing between the strips depends on the type of finishing material. Wider spacing is typically used behind the heavy boards tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Princes Channel Wreck
The Princes Channel wreck, also known as the Gresham Ship is an Elizabethan shipwreck (c. 1574) that was discovered in the Princes Channel in the Thames Estuary. It was discovered by the Port of London Authority in 2004 during a dredging operation to remove obstructions that posed hazards and impeded navigation during low tides (Auer, J. and Firth, A.). Archaeological remains 20% of the wreck was recovered and lifted from the Thames Estuary, excavated and recovered by Wessex Archaeology. It was then taken to Horsea Island, an estuarine lake near Portsmouth so it could be preserved. A five-year research project ("The Gresham Ship Project"), was carried out from 2007 to 2012 by researchers from University College London and the University of Southern Denmark. The project focused on five large sections of the hull that had been recovered, as well as associated artefacts. The hull timbers are now a major exhibit at the UK National Dive Centre at Stoney Cove. The design and construc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Construction
Construction is a general term meaning the art and science to form objects, systems, or organizations,"Construction" def. 1.a. 1.b. and 1.c. ''Oxford English Dictionary'' Second Edition on CD-ROM (v. 4.0) Oxford University Press 2009 and comes from Latin ''constructio'' (from ''com-'' "together" and ''struere'' "to pile up") and Old French ''construction''. To construct is the verb: the act of building, and the noun is construction: how something is built, the nature of its structure. In its most widely used context, construction covers the processes involved in delivering buildings, infrastructure, industrial facilities and associated activities through to the end of their life. It typically starts with planning, financing, and design, and continues until the asset is built and ready for use; construction also covers repairs and maintenance work, any works to expand, extend and improve the asset, and its eventual demolition, dismantling or decommissioning.

Batten
A batten is most commonly a strip of solid material, historically wood but can also be of plastic, metal, or fiberglass. Battens are variously used in construction, sailing, and other fields. In the lighting industry, battens refer to linear light fittings. In the steel industry, battens used as furring may also be referred to as "top hats", in reference to the profile of the metal. Roofing ''Roofing battens'' or ''battening'', also called ''roofing lath'', are used to provide the fixing point for roofing materials such as shingles or tiles. The spacing of the battens on the trusses or rafters depend on the type of roofing material and are applied horizontally like purlins. Battens are also used in metal roofing to secure the sheets called a ''batten-seam roof'' and are covered with a ''batten roll joint''. Some roofs may use a grid of battens in both directions, known as a ''counter-batten system'', which improves ventilation. Roofing battens are most commonly made of ...

Lath And Plaster
Lath and plaster is a building process used to finish mainly interior dividing walls and ceilings. It consists of narrow strips of wood ( laths) which are nailed horizontally across the wall studs or ceiling joists and then coated in plaster. The technique derives from an earlier, more primitive process called wattle and daub. Lath and plaster largely fell out of favour in the U.K. after the introduction of plasterboard in the 1930s.Jeff Howell''On the level: is the old plaster best?'' The Telegraph (London), May 10, 2006. Retrieved 2012-03-30. In Canada and the United States, wood lath and plaster remained in use until the process was replaced by transitional methods followed by drywall (the North American term for plasterboard) in the mid-twentieth century. Description The wall or ceiling finishing process begins with wood or metal laths. These are narrow strips of wood, extruded metal, or split boards, nailed horizontally across the wall studs or ceiling joists. Each wall fr ...

Wattle And Daub
Wattle and daub is a composite building method used for making walls and buildings, in which a woven lattice of wooden strips called wattle is daubed with a sticky material usually made of some combination of wet soil, clay, sand, animal dung and straw. Wattle and daub has been used for at least 6,000 years and is still an important construction method in many parts of the world. Many historic buildings include wattle and daub construction. History The wattle and daub technique was used already in the Neolithic period. It was common for houses of Linear pottery and Rössen cultures of middle Europe, but is also found in Western Asia (Çatalhöyük, Shillourokambos) as well as in North America (Mississippian culture) and South America (Brazil). In Africa it is common in the architecture of traditional houses such as those of the Ashanti people. Its usage dates back at least 6,000 years. There are suggestions that construction techniques such as lath and plaster and even cob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plywood
Plywood is a material manufactured from thin layers or "plies" of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another. It is an engineered wood from the family of manufactured boards which include medium-density fibreboard (MDF), oriented strand board (OSB) and particle board (chipboard). All plywoods bind resin and wood fibre sheets (cellulose cells are long, strong and thin) to form a composite material. This alternation of the grain is called ''cross-graining'' and has several important benefits: it reduces the tendency of wood to split when nailed at the edges; it reduces expansion and shrinkage, providing improved dimensional stability; and it makes the strength of the panel consistent across all directions. There is usually an odd number of plies, so that the sheet is balanced—this reduces warping. Because plywood is bonded with grains running against one another and with an odd number of composite part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drywall
Drywall (also called plasterboard, dry lining, wallboard, sheet rock, gypsum board, buster board, custard board, and gypsum panel) is a panel made of calcium sulfate dihydrate (gypsum), with or without additives, typically extruded between thick sheets of facer and backer paper, used in the construction of interior walls and ceilings. The plaster is mixed with fiber (typically paper, glass wool, or a combination of these materials); plasticizer, foaming agent; and additives that can reduce mildew, flammability, and water absorption. In the middle of the 20th century, drywall construction became prevalent in North America as a time- and labor-saving alternative to lath and plaster. History The first plasterboard plant in the UK was opened in 1888 in Rochester, Kent. Sackett Board was invented in 1894 by Augustine Sackett and Fred Kane, graduates of Rensselaer Polytechnic Institute. It was made by layering plaster within four plies of wool felt paper. Sheets were thick with o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Strake
On a vessel's hull, a strake is a longitudinal course of planking or plating which runs from the boat's stempost (at the bows) to the sternpost or transom (at the rear). The garboard strakes are the two immediately adjacent to the keel on each side. The word derives from traditional wooden boat building methods, used in both carvel and clinker construction. In a metal ship, a strake is a course of plating. Construction In small boats strakes may be single continuous pieces of wood. In larger wooden vessels strakes typically comprise several planks which are either scarfed, or butt-jointed and reinforced with a butt block. Where the transverse sections of the vessel's shape are fuller, the strakes are wider; they taper toward the ends. In a riveted steel ship, the strakes were usually lapped and joggled (one strake given projections to match indentions in the one adjoining), but where a smoother finish was sought they might be riveted on a butt strap, though this w ...

Transverse Stability
The metacentric height (GM) is a measurement of the initial static stability of a floating body. It is calculated as the distance between the centre of gravity of a ship and its metacentre. A larger metacentric height implies greater initial stability against overturning. The metacentric height also influences the natural period of rolling of a hull, with very large metacentric heights being associated with shorter periods of roll which are uncomfortable for passengers. Hence, a sufficiently, but not excessively, high metacentric height is considered ideal for passenger ships. Metacentre When a ship heels (rolls sideways), the centre of buoyancy of the ship moves laterally. It might also move up or down with respect to the water line. The point at which a vertical line through the heeled centre of buoyancy crosses the line through the original, vertical centre of buoyancy is the metacentre. The metacentre remains directly above the centre of buoyancy by definition. In the diagra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
