Negrelli Viaduct
The Negrelli Viaduct (''Czech'': ''Negrelliho viadukt'' by Alois Negrelli, also known as the Karlín Viaduct,), Czech republic, is a railway bridge over the Štvanice island that connects the Masaryk Railway Station in Prague with Bubny. It is historically the first Prague railway bridge over the Vltava and currently it is the second oldest Prague bridge over this river and its thirteenth downstream bridge in the capital. It is also the longest railway bridge and the third longest bridge in the Czech Republic. The viaduct was declared a Czech cultural monument in 1964. History Construction The Karlín Viaduct was built as part of the Dresden branch of the Northern State Railways Olomouc-Prague-Dresden project, which was approved by the State Railways Directorate in 1842. The construction started in spring 1846, was completed in 1849 and the bridge was put into operation on 1 June 1850. The construction costs amounted to one and a half million florins. At that t ...

Vltava
Vltava ( , ; german: Moldau ) is the longest river in the Czech Republic, running southeast along the Bohemian Forest and then north across Bohemia, through Český Krumlov, České Budějovice and Prague, and finally merging with the Labe at Mělník. It is commonly referred to as the " Czech national river". Both the Czech name ' and the German name ' are believed to originate from the old Germanic words ' 'wild water' (compare Latin '). In the ' (872 AD) it is called '; from 1113 AD it is attested as '. In the ' (1125 AD) it is attested for the first time in its Bohemian form, '. Course The Vltava River is long and drains an area of in size, over half of Bohemia and about a third of the Czech Republic's entire territory. As it runs through Prague, the river is crossed by 18 bridges (including the Charles Bridge) and covers within the city. The water from the river was used for drinking until 1912 when the Vinohrady Water Tower ceased pumping operations. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olomouc
Olomouc (, , ; german: Olmütz; pl, Ołomuniec ; la, Olomucium or ''Iuliomontium'') is a city in the Czech Republic. It has about 99,000 inhabitants, and its larger urban zone has a population of about 384,000 inhabitants (2019). Located on the Morava River, the city is the ecclesiastical metropolis and was a historical capital city of Moravia, before having been sacked by the Swedish army during the Thirty Years' War.

Prestressed Concrete
Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" (Compression (physics), compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service. Post-tensioned concreted is "structural concrete in which internal stresses have been introduced to reduce potential tensile stresses in the concrete resulting from loads." This compression is produced by the Tension (physics), tensioning of high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in service. Tendons may consist of single wires, multi-wire Wire rope, strands or threaded bars that are most commonly made from high-tensile steels, carbon fiber or aramid fiber. The essence of prestressed concrete is that once the initial compression has been applied, the resulting material has the characteristics of high-strength concrete when subject to any subsequent compression fo ...

Lintel
A lintel or lintol is a type of beam (a horizontal structural element) that spans openings such as portals, doors, windows and fireplaces. It can be a decorative architectural element, or a combined ornamented structural item. In the case of windows, the bottom span is instead referred to as a sill, but, unlike a lintel, does not serve to bear a load to ensure the integrity of the wall. Modern day lintels are made using prestressed concrete and are also referred to as beams in beam and block slabs or ribs in rib and block slabs. These prestressed concrete lintels and blocks are components that are packed together and propped to form a suspended floor concrete slab. Structural uses In worldwide architecture of different eras and many cultures, a lintel has been an element of post and lintel construction. Many different building materials have been used for lintels. In classical Western architecture and construction methods, by ''Merriam-Webster'' definition, a lintel is ...

Craft
A craft or trade is a pastime or an occupation that requires particular skills and knowledge of skilled work. In a historical sense, particularly the Middle Ages and earlier, the term is usually applied to people occupied in small scale production of goods, or their maintenance, for example by tinkers. The traditional term ''craftsman'' is nowadays often replaced by ''artisan'' and by ''craftsperson'' ( craftspeople). Historically, the more specialized crafts with high-value products tended to concentrate in urban centers and formed guilds. The skill required by their professions and the need to be permanently involved in the exchange of goods often demanded a generally higher level of education, and craftsmen were usually in a more privileged position than the peasantry in societal hierarchy. The households of craftsmen were not as self-sufficient as those of people engaged in agricultural work, and therefore had to rely on the exchange of goods. Some crafts, especi ...

Grating
A grating is any regularly spaced collection of essentially identical, parallel, elongated elements. Gratings usually consist of a single set of elongated elements, but can consist of two sets, in which case the second set is usually perpendicular to the first (as illustrated). When the two sets are perpendicular, this is also known as a wikt:grid (as in grid paper) or a mesh. As filters A grating covering a drain (as illustrated) can be a collection of iron bars (the identical, elongated elements) held together (to ensure the bars are parallel and regularly spaced) by a lighter iron frame. Gratings over drains and air vents are used as filters, to block movement of large solids (e.g. people) and to allow movement of liquids. A register is a type of grating used in heating, ventilation, and air conditioning, which transmits air, while stopping solid objects.

Masonry
Masonry is the building of structures from individual units, which are often laid in and bound together by mortar; the term ''masonry'' can also refer to the units themselves. The common materials of masonry construction are bricks, building stone such as marble, granite, and limestone, cast stone, concrete blocks, glass blocks, and adobe. Masonry is generally a highly durable form of construction. However, the materials used, the quality of the mortar and workmanship, and the pattern in which the units are assembled can substantially affect the durability of the overall masonry construction. A person who constructs masonry is called a mason or bricklayer. These are both classified as construction trades. Applications Masonry is commonly used for walls and buildings. Brick and concrete block are the most common types of masonry in use in industrialized nations and may be either load-bearing or non-load-bearing. Concrete blocks, especially those with hollow cores, offer v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
