Roof Tiles
Roof tiles are overlapping tiles designed mainly to keep out precipitation such as rain or snow, and are traditionally made from locally available materials such as clay or slate. Later tiles have been made from materials such as concrete, glass, and plastic. Roof tiles can be affixed by screws or nail (fastener), nails, but in some cases historic designs utilize interlocking systems that are self-supporting. Tiles typically cover an List of commercially available roofing materials, underlayment system, which seals the roof against water intrusion. Categories There are numerous profiles, or patterns, of roof tile, which can be separated into categories based on their installation and design. Shingle / flat tiles One of the simplest designs of roof tile, these are simple overlapping slabs installed in the same manner as traditional roof shingle, shingles, usually held in place by nails or screws at their top. All forms of slate tile fall into this category. When installed, mos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imbrex And Tegula
The imbrex and tegula (: imbrices and tegulae) were overlapping roof tiles used in ancient Greek and Roman architecture as a waterproof and durable roof covering. They were made predominantly of fired clay, but also sometimes of marble, bronze or gilt. In Rome, they replaced wooden shingles, and were used on almost every type of structure, from humble outbuildings to grand temples and public facilities. The tegula (Greek solenes) was a plain flat tile, or a flat tile with raised edges, which was laid flat upon the roof, while the imbrex (Greek kalupter) was a semi-cylindrical roofing tile, like a half-pipe, laid over the joints between the tegulae. When well-made and properly imbricated (overlapped), there was little need for further waterproofing or sealant. The roofing area was generally surrounded by antefixae, which were often decorated and had several decorative anthemia to cover each end row imbrex. The concept of imbrex and tegula roofing in pitched roof constructi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Greece
Ancient Greece () was a northeastern Mediterranean civilization, existing from the Greek Dark Ages of the 12th–9th centuries BC to the end of classical antiquity (), that comprised a loose collection of culturally and linguistically related city-states and communities. Prior to the Roman period, most of these regions were officially unified only once under the Kingdom of Macedon from 338 to 323 BC. In Western history, the era of classical antiquity was immediately followed by the Early Middle Ages and the Byzantine period. Three centuries after the decline of Mycenaean Greece during the Bronze Age collapse, Greek urban poleis began to form in the 8th century BC, ushering in the Archaic period and the colonization of the Mediterranean Basin. This was followed by the age of Classical Greece, from the Greco-Persian Wars to the death of Alexander the Great in 323 BC, and which included the Golden Age of Athens and the Peloponnesian War.

Neolithic Period
The Neolithic or New Stone Age (from Greek 'new' and 'stone') is an archaeological period, the final division of the Stone Age in Mesopotamia, Asia, Europe and Africa (c. 10,000 BCE to c. 2,000 BCE). It saw the Neolithic Revolution, a wide-ranging set of developments that appear to have arisen independently in several parts of the world. This "Neolithic package" included the introduction of farming, domestication of animals, and change from a hunter-gatherer lifestyle to one of settlement. The term 'Neolithic' was coined by Sir John Lubbock in 1865 as a refinement of the three-age system. The Neolithic began about 12,000 years ago, when farming appeared in the Epipalaeolithic Near East and Mesopotamia, and later in other parts of the world. It lasted in the Near East until the transitional period of the Chalcolithic (Copper Age) from about 6,500 years ago (4500 BCE), marked by the development of metallurgy, leading up to the Bronze Age and Iron Age. In other places, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Machine Press
A forming press, commonly shortened to press, is a machine tool that changes the shape of a work-piece by the application of pressure. The operator of a forming press is known as a press-tool setter, often shortened to tool-setter. Presses can be classified according to * their mechanism: Hydraulic press, hydraulic, Machine (mechanical) , mechanical, Pneumatics, pneumatic; * their function: forging presses, stamping presses, press brakes, punch press, etc. * their structure, e.g. Knuckle-joint press, screw press, Expeller pressing, Expeller press * their controllability: conventional vs. Servo press, servo-presses Shop Press Typically consisting of a simple rectangular frame, often fabrication (metal), fabricated from Structural channel, C-channel or tubing, containing a Jack (device)#Bottle jack, bottle jack or hydraulic cylinder to apply pressure via a ram to a work-piece. Often used for general-purpose forming work in the auto mechanic shop, machine shop, garage or basem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scandinavia
Scandinavia is a subregion#Europe, subregion of northern Europe, with strong historical, cultural, and linguistic ties between its constituent peoples. ''Scandinavia'' most commonly refers to Denmark, Norway, and Sweden. It can sometimes also refer to the Scandinavian Peninsula (which excludes Denmark but includes a part of northern Finland). In English usage, Scandinavia is sometimes used as a synonym for Nordic countries. Iceland and the Faroe Islands are sometimes included in Scandinavia for their Ethnolinguistics, ethnolinguistic relations with Sweden, Norway and Denmark. While Finland differs from other Nordic countries in this respect, some authors call it Scandinavian due to its economic and cultural similarities. The geography of the region is varied, from the Norwegian fjords in the west and Scandinavian mountains covering parts of Norway and Sweden, to the low and flat areas of Denmark in the south, as well as archipelagos and lakes in the east. Most of the population ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extruder
Extrusion is a process used to create objects of a fixed cross-sectional profile by pushing material through a die of the desired cross-section. Its two main advantages over other manufacturing processes are its ability to create very complex cross-sections; and to work materials that are brittle, because the material encounters only compressive and shear stresses. It also creates excellent surface finish and gives considerable freedom of form in the design process. Drawing is a similar process, using the tensile strength of the material to pull it through the die. It limits the amount of change that can be performed in one step, so it is limited to simpler shapes, and multiple stages are usually needed. Drawing is the main way to produce wire. Metal bars and tubes are also often drawn. Extrusion may be continuous (theoretically producing indefinitely long material) or semi-continuous (producing many pieces). It can be done with hot or cold material. Commonly extruded mate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pantile
A pantile is a type of fired roof tile, normally made from clay. It is S-shaped in profile and is single lap, meaning that the end of the tile laps only the course immediately below. Flat tiles normally lap two courses. A pantile-covered roof is considerably lighter than a flat-tiled equivalent and can be laid to a lower pitch. In Britain, pantiles are found in eastern coastal parts of England and Scotland including Norfolk, East Yorkshire, County Durham, Perthshire, Angus, Lothian and Fife, where they were first imported from the Netherlands in the early 17th century. They are rarely used in western England or western Scotland, except in Bristol and the Somerset town of Bridgwater. In paving Roofing pantiles are not to be confused with the paving tiles also named "pantiles." The Pantiles in Royal Tunbridge Wells is named for the paving tiles installed there in 1699 — one-inch-thick square tiles made from heavy weald The Weald () is an area of South East England b ...

Roof Tiles 3 (29910828253)
A roof (: roofs or rooves) is the top covering of a building, including all materials and constructions necessary to support it on the walls of the building or on uprights, providing protection against rain, snow, sunlight, extremes of temperature, and wind. A roof is part of the building envelope. The characteristics of a roof are dependent upon the purpose of the building that it covers, the available roofing materials and the local traditions of construction and wider concepts of architectural design and practice, and may also be governed by local or national legislation. In most countries, a roof protects primarily against rain. A verandah may be roofed with material that protects against sunlight but admits the other elements. The roof of a garden conservatory protects plants from cold, wind, and rain, but admits light. A roof may also provide additional living space, for example, a roof garden. Etymology Old English 'roof, ceiling, top, summit; heaven, sky', also fig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monk And Nun
Monk and Nun, also known as pan and cover, mission tiling, Spanish tile, gutter tile, or barrel tile, is a style of arranging roof tiles, using semi-cylindrical tiles similar to imbrex and tegula, but instead of alternating rows of flat tiles (tegulae) and arched tiles (imbrices), both rows consist of the arched tile. The top row with the convex side facing up are the ''monk'' tiles while the bottom row with the convex side facing down are the ''nun'' tiles. Mortar (masonry), Mortar is often used under the ''monk'' tile to firmly attach it to the ''nun'' tile, though this can lead to failure in areas with cold winters. Roofs with terracotta Monk and Nun started appearing in Southern Europe during the Middle Ages. Originally, the tiles were made from locally sourced clay and given its shape with the help of a curved surface, such as a log or the maker's thigh. With time, regions developed a preference for a specific tile size, curve shape (profile), and color or colors. Today, M ...
