Bullnose
A bullnose is a broad convex radius on construction materials such as wood, masonry, and ceramic tile. The term is also used for materials featuring such a profile, as in a “bullnose tile”. It is also used in relation to road safety and (formerly) railroad engineering design. Uses A bullnose profile is used both for safety and decorative effect, as an alternative to a flat-edged chamfer. It is variously added to construction materials with tools such as a mill, plane, and bit in a shaper or router. Trim with a bullnose profile is used to provide a smooth, rounded edge for countertops, staircase steps, building corners, or other construction. Masonry units such as bricks, concrete masonry units, or structural glazed facing tiles may be ordered from manufacturers with bullnosed edges and corners. The standard bullnose terminology refers to a one-quarter profile; two adjacent quarter profiles constitute a half bullnose. Rather than being machined from a single piece of mat ...

Morris Oxford Bullnose
The "bullnose" Morris Oxford is a series of automobile, motor car models produced by British manufacturer Morris Motors, Morris from 1913 to 1926. It was named by William Morris, 1st Viscount Nuffield, W R Morris after the city in which he grew up and which his cars were to industrialise. Oxford ''bullnose'' (1913–1916) William Morris's first car was called Oxford in recognition of its Oxford, home city. It was announced in ''Autocar (magazine), The Autocar'' magazine in October 1912 and production began in March 1913.''The Bullnose and Flatnose Morris'', Lytton P Jarman and Robin I Barraclough, David & Charles, Newton Abbot 1976 Because he had a limited amount of capital and was unwilling to share ownership of his business little was made in-house. Virtually all components were bought-in and assembled by Morris. It was a small car with a 1018 cc four-cylinder side-valve engine with fixed cylinder head from White and Poppe, White & Poppe.

Clerestory
A clerestory ( ; , also clearstory, clearstorey, or overstorey; from Old French ''cler estor'') is a high section of wall that contains windows above eye-level. Its purpose is to admit light, fresh air, or both. Historically, a ''clerestory'' formed an upper level of a Roman basilica or of the nave of a Romanesque architecture, Romanesque or Gothic architecture, Gothic church (building), church, the walls of which rise above the rooflines of the lower aisles and which are pierced with windows. In addition to architecture, #Transportation, clerestories have been used in transportation vehicles such as buses and trains to provide additional lighting, ventilation, or headroom. History Ancient world Clerestories appear to originate in Egyptian temples, where the lighting of the hall of columns was obtained over the stone roofs of the adjoining aisles, through gaps left in the vertical slabs of stone. They appeared in Egypt at least as early as the Amarna Period. Minoan palaces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chamfer
A chamfer ( ) is a transitional edge between two faces of an object. Sometimes defined as a form of bevel, it is often created at a 45° angle between two adjoining right-angled faces. Chamfers are frequently used in machining, carpentry, furniture, concrete formwork, mirrors, and to facilitate assembly of many mechanical engineering designs. Terminology In materials and manufacturing, a ''chamfer'' is used to "ease" otherwise sharp edges, both for safety and to prevent damage to the edges; it may also be a primarily decorative feature. In general terms it may be regarded as a type of ''bevel'', and the terms are often used interchangeably. However, in machining, only the term chamfer is used for the specific technique, practice, and result. In carpentry, a lark's tongue is a chamfer which ends short of the end of a piece in a gradual outward curve, leaving the remainder of the edge as a right angle. Chamfers may be formed in either inside or outside adjoining faces of an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concrete Masonry Unit
A concrete block, also known as a cinder block in North American English, breeze block in British English, or concrete masonry unit (CMU), or by various other terms, is a standard-size rectangular block used in building construction. The use of blockwork allows structures to be built in the traditional masonry style with layers (or courses) of staggered blocks. Concrete blocks may be produced with hollow centers (cores) to reduce weight, improve insulation and provide an interconnected void into which concrete can be poured to solidify the entire wall after it is built. Concrete blocks are some of the most versatile building products available because of the wide variety of appearances that can be achieved using them. Naming Those that use cinders (fly ash or bottom ash) as an aggregate material are called ''cinder blocks'' in the United States. They are also known as ''breeze blocks'', a term derived from ''breeze'', referring to the small cinders and cinder-dust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceramic Tile
Tiles are usually thin, square or rectangular coverings manufactured from hard-wearing material such as ceramic, stone, metal, baked clay, or even glass. They are generally fixed in place in an array to cover roofs, floors, walls, edges, or other objects such as tabletops. Alternatively, tile can sometimes refer to similar units made from lightweight materials such as perlite, wood, and mineral wool, typically used for wall and ceiling applications. In another sense, a tile is a construction tile or similar object, such as rectangular counters used in playing games (see tile-based game). The word is derived from the French word ''tuile'', which is, in turn, from the Latin word ''tegula'', meaning a roof tile composed of fired clay. Tiles are often used to form wall and floor coverings, and can range from simple square tiles to complex or mosaics. Tiles are most often made of ceramic, typically glazed for internal uses and unglazed for roofing, but other materials are also c ...

Structural Glazed Facing Tile
Structural clay tile describes a category of burned-clay building materials used to construct roofing, walls, and flooring for structural and non-structural purposes, especially in fireproofing applications. Also called building tile, structural terra cotta, hollow tile, saltillo tile, and clay block, the material is an extruded clay shape with substantial depth that allows it to be laid in the same manner as other clay or concrete masonry. In North America, it was mainly used during the late 19th and early 20th centuries, reaching peak popularity at the turn of the century and declining around the 1950s. Structural clay tile grew in popularity in the end of the nineteenth-century because it could be constructed faster, was lighter, and required simpler flat falsework than earlier brick vaulting construction. Each unit is generally made of clay or terra-cotta with hollow cavities, or cells, inside it. The colors of terracotta transform from gray (raw, moist clay) to orange, red, ...

Crash Barrier
Traffic barriers (known in North America as guardrails or guard rails, in Britain as crash barriers, and in auto racing as Armco barriers AK Steel (formerly Armco) genericized trademark) keep vehicles within their roadway and prevent them from colliding with dangerous obstacles such as boulders, sign supports, trees, bridge abutments, buildings, walls, and large storm drains, or from traversing steep (non-recoverable) slopes or entering deep water. They are also installed within medians of divided highways to prevent errant vehicles from entering the opposing carriageway of traffic and help to reduce head-on collisions. Some of these barriers, designed to be struck from either side, are called median barriers. Traffic barriers can also be used to protect vulnerable areas like school yards, pedestrian zones, and fuel tanks from errant vehicles. In pedestrian zones, like school yards, they also prevent children or other pedestrians from running onto the road. While barriers are nor ...

Jersey Barrier
A Jersey barrier, Jersey wall, or Jersey bump is a modular concrete or plastic barrier employed to separate lanes of traffic. It is designed to minimize vehicle damage in cases of incidental contact while still preventing vehicle crossovers resulting in a likely Head-on collision#Road transport, head-on collision. Jersey barriers are also used to reroute traffic and protect pedestrians and workers during highway construction. They are named after the U.S. state of New Jersey which first started using the barriers as separators between lanes of a highway in the 1950s. The barriers are also known as a K-rail, a term stipulated in the California Department of Transportation specification for temporary concrete traffic barriers which first started using concrete median barriers in the mid-1940s. Over time, different variants were created. Taller variants, such as the Ontario Tall Wall, proved more effective at stopping vehicles and had the added advantage of blocking most oncomin ...
