Covering (construction)
In construction, covering is the exterior layer of a building's roof. The covering ensures waterproofing by directing and collecting rainwater. It also provides mechanical protection against various external elements such as dust and intrusions. Additionally, it must withstand static mechanical pressures from snow and dynamic forces from strong winds (pressure and uplift). Considered as the fifth Façade, facade of the building, it also contributes to the Aesthetics, aesthetic appeal and character of the structure. Functions The roof covering is the exterior part of the roof and does not contribute to the building's stability. It is designed to endure all weather conditions such as rain, snow, hail, and wind, as well as external environmental factors like marine environments and the weight of maintenance personnel. From the ridge to the drainage system, the roof covering directs rainwater by gravity and contributes to waterproofing. As a visible element from the outside, the ro ...

Bundesarchiv Bild 183-1984-0803-028, Berlin, VEB Baureparaturen Lichtenberg Jugendbrigade
The German Federal Archives or Bundesarchiv (BArch) (, lit. "Federal Archive") are the national archives of Germany. They were established at the current location in Koblenz in 1952. They are subordinated to the Federal Commissioner for Culture and the Media (Claudia Roth since 2021) under the German Chancellery, and before 1998, to the Federal Ministry of the Interior (Germany), Federal Ministry of the Interior. On 6 December 2008, the Archives donated 100,000 photos to the public, by making them accessible via Wikimedia Commons. History The federal archive for institutions and authorities in Germany, the first precursor to the present-day Federal Archives, was established in Potsdam, Brandenburg in 1919, a later date than in other European countries. This national archive documented German government dating from the founding of the North German Confederation in 1867. It also included material from the older German Confederation and the Imperial Chamber Court. The oldest docum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prefabricated
Prefabrication is the practice of assembling components of a structure in a factory or other manufacturing site, and transporting complete assemblies or sub-assemblies to the construction site where the structure is to be located. Some researchers refer it to “various materials joined together to form a component of the final installation procedure“. The most commonly cited definition is by Goodier and Gibb in 2007, which described the process of manufacturing and preassembly of a certain number of building components, modules, and elements before their shipment and installation on construction sites. The term ''prefabrication'' also applies to the manufacturing of things other than structures at a fixed site. It is frequently used when fabrication of a section of a machine or any movable structure is shifted from the main manufacturing site to another location, and the section is supplied assembled and ready to fit. It is not generally used to refer to electrical or elect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Building Code
A building code (also building control or building regulations) is a set of rules that specify the standards for construction objects such as buildings and non-building structures. Buildings must conform to the code to obtain planning permission, usually from a local council. The main purpose of building codes is to protect public health, safety and general welfare as they relate to the construction and occupancy of buildings and for example, the building codes in many countries require engineers to consider the effects of soil liquefaction in the design of new buildings. The building code becomes law of a particular jurisdiction when formally enacted by the appropriate governmental or private authority. Building codes are generally intended to be applied by architects, engineers, interior designers, constructors and regulators but are also used for various purposes by safety inspectors, environmental scientists, real estate developers, subcontractors, manufacturers of b ...

Rafter
A rafter is one of a series of sloped structural members such as Beam (structure), steel beams that extend from the ridge or hip to the wall plate, downslope perimeter or eave, and that are designed to support the roof Roof shingle, shingles, roof deck, roof covering and its associated loads. A pair of rafters is called a ''couple''. In home construction, rafters are normally made of wood. Exposed rafters are a feature of some traditional roof styles. Applications In recent buildings there is a preference for trussed rafters on the grounds of cost, economy of materials, off-site manufacture, and ease of construction, as well as design considerations including span limitations and roof loads (weight from above). Types in traditional timber framing There are many names for rafters depending on their location, shape, or size (see below). The earliest surviving roofs in Europe are of common rafters on a tie beam; this assembly is known as a "closed couple". Later, principal raf ...

Capillarity
Capillary action (sometimes called capillarity, capillary motion, capillary rise, capillary effect, or wicking) is the process of a liquid flowing in a narrow space without the assistance of external forces like Gravitation, gravity. The effect can be seen in the drawing up of liquids between the hairs of a paint-brush, in a thin tube such as a Drinking straw, straw, in porous materials such as paper and plaster, in some non-porous materials such as clay and liquefied carbon fiber, or in a biological cell. It occurs because of intermolecular forces between the liquid and surrounding solid surfaces. If the diameter of the tube is sufficiently small, then the combination of surface tension (which is caused by Cohesion (chemistry), cohesion within the liquid) and Adhesion, adhesive forces between the liquid and container wall act to propel the liquid. Etymology Capillary comes from the Latin word capillaris, meaning "of or resembling hair". The meaning stems from the tiny, hairl ...

Rainwater
Rain is a form of precipitation where water droplets that have condensed from atmospheric water vapor fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides water for hydroelectric power plants, crop irrigation, and suitable conditions for many types of ecosystems. The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts. If enough moisture and upward motion is present, precipitation falls from convective clouds (those with strong upward vertical motion) such as cumulonimbus (thunder clouds) which can organize into narrow rainbands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and fall out as rainfall along the sides of mountains. On the leeward side of mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Palais
The (; ), commonly known as the , is a historic site, exhibition hall and museum complex located in the 8th arrondissement of Paris between the Champs-Élysées and the Seine, France. Construction of the began in 1897 following the demolition of the Palais de l'Industrie (Palace of Industry) to prepare for the Exposition Universelle (1900), Universal Exposition of 1900. That exposition also produced the adjacent and Pont Alexandre III. The building was designed to be a large-scale venue for official artistic events. A pediment on the building refers to this function with an inscription that reads, "a monument dedicated by the Republic to the glory of French art." Designed according to Beaux-Arts architecture, Beaux-Arts tastes, the building features ornate stone facades, glass vaults and period innovations that included iron and Steel frame, light steel framing and reinforced concrete. It is listed as a historic monument () by the Ministry of Culture (France), Ministry of C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reichstag Building
The Reichstag (; ) is a historic legislative government building on Platz der Republik in Berlin that is the seat of the German Bundestag. It is also the meeting place of the Federal Convention, which elects the President of Germany. The Neo-Renaissance building was constructed between 1884 and '94 in the Tiergarten district on the left bank of the River Spree to plans by the architect Paul Wallot. It housed the Reichstag (legislature) of the German Empire and subsequent Weimar Republic. The Reich's Federal Council also originally met there. The building was initially used by the Reichstag for Nazi Germany, but severe damage in the Reichstag fire of 1933 prevented further use and the Reichstag moved to the nearby Kroll Opera House. The 1933 fire became a pivotal event in the entrenchment of the Nazi regime. The building took further damage during World War II, and its symbolism made it an important target for the Red Army during the Battle of Berlin. After the war, t ...

Orangery
An orangery or orangerie is a room or dedicated building, historically where orange and other fruit trees are protected during the winter, as a large form of greenhouse or conservatory. In the modern day an orangery could refer to either a conservatory or greenhouse built to house fruit trees, or a conservatory or greenhouse meant for another purpose. The orangery provided a luxurious extension of the normal range and season of woody plants, extending the protection which had long been afforded by the warmth offered from a masonry fruit wall. During the 17th century, fruits like orange, pomegranate, and bananas arrived in huge quantities to European ports. Since these plants were not adapted to the harsh European winters, orangeries were invented to protect and sustain them. The high cost of glass made orangeries a status symbol showing wealth and luxury. Gradually, due to technological advancements, orangeries became more of a classic architectural structure that enh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
