Lintel Arch
A jack arch is a structural element in masonry construction that provides support at openings in the masonry. Alternate names are lintel arch, flat arch and straight arch. Unlike regular arches, jack arches are not curved in form. Instead, they are flat in profile and are used under the same circumstances as lintels. Unlike lintels, which are subject to bending stress, jack arches are composed of individual masonry elements cut or formed into a wedge shape that efficiently uses the compressive strength of the masonry in the same manner as a regular arch. Like regular arches, jack arches require a mass of masonry to either side to absorb the considerable lateral thrust created by the jack arch. Jack arches have the advantage of being constructed from smaller pieces of material that can be handled by individuals, as opposed to lintels which must necessarily be monolithic and which must be oversized unless reinforced by other means. In small-scale brick masonry projects, jack arch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Masonry
Masonry is the craft of building a structure with brick, stone, or similar material, including mortar plastering which are often laid in, bound, and pasted together by mortar (masonry), mortar. The term ''masonry'' can also refer to the building units (stone, brick, etc.) themselves. The common materials of masonry construction are bricks and building stone, rock (geology), rocks such as marble, granite, and limestone, cast stone, concrete masonry unit, concrete blocks, glass brick, 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 worker, construction trades. History Masonry is one of the oldest building crafts in the world. The constructio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arch
An arch is a curved vertical structure spanning an open space underneath it. Arches may support the load above them, or they may perform a purely decorative role. As a decorative element, the arch dates back to the 4th millennium BC, but structural load-bearing arches became popular only after their adoption by the Ancient Romans in the 4th century BC. Arch-like structures can be horizontal, like an arch dam that withstands the horizontal hydrostatic pressure load. Arches are usually used as supports for many types of vaults, with the barrel vault in particular being a continuous arch. Extensive use of arches and vaults characterizes an arcuated construction, as opposed to the trabeated system, where, like in the architectures of ancient Greece, China, and Japan (as well as the modern steel-framed technique), posts and beams dominate. Arches had several advantages over the lintel, especially in the masonry construction: with the same amount of material it can have ...

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 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 may be made using prestressed concrete and are also referred to as beams in beam-and-block slabs or as ribs in rib-and-block slabs. These prestressed concrete lintels and blocks can serve as components that are packed together and propped to form a suspended-floor concrete slab. An arch functions as a curved lintel. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keystone (architecture)
A keystone (or capstone) is the wedge-shaped stone at the apex (geometry), apex of a masonry arch or typically round-shaped one at the apex of a Vault (architecture), vault. In both cases it is the final piece placed during construction and locks all the stones into position, allowing the arch or vault to bear weight. In arches and vaults (such as quasi-domes) keystones are often enlarged beyond the structural requirements and decorated. A variant in domes and crowning vaults is a lantern (architecture), lantern. A portion of the arch surrounding the keystone is called a Crown (arch), crown. Keystones or their suggested form are sometimes placed for decorative effect in the centre of the flat top of doors, recesses and windows, so as to form an upward projection of a lintel, as a hallmark of strength or good architecture. Although a masonry arch or vault cannot be self-supporting until the keystone is placed, the keystone experiences the least stress of any of the voussoirs, ...

Polychrome
Polychrome is the "practice of decorating architectural elements, sculpture, etc., in a variety of colors." The term is used to refer to certain styles of architecture, pottery, or sculpture in multiple colors. When looking at artworks and architecture from antiquity and the European Middle Ages, people tend to believe that they were monochrome. In reality, the pre-Renaissance past was full of colour, and Greco-Roman sculptures and Gothic cathedrals, that are now white, beige, or grey, were initially painted in a variety of colours. As André Malraux stated: "Athens was never white but her statues, bereft of color, have conditioned the artistic sensibilities of Europe ..the whole past has reached us colorless." Polychrome was and is a practice not limited only to the Western world. Non-Western artworks, like Chinese temples, Oceanian Uli figures, or Maya ceramic vases, were also decorated with colours. Ancient Near East Similarly to the ancient art of other regions, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mor Hananyo Monastery
Mor Hananyo Monastery or Monastery of Saint Ananias (; ) is an important Syriac Orthodox Church, Syriac Orthodox monastery located five kilometers south east of Mardin, Turkey, in the Assyrian culture, Syriac cultural region known as Tur Abdin.

In the Roman period, the city itself was known as ''Marida'' (''Merid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arches And Vaults
An arch is a curved vertical structure span (engineering), spanning an open space underneath it. Arches may support the load above them, or they may perform a purely decorative role. As a decorative element, the arch dates back to the 4th millennium BC, but structural load-bearing arches became popular only after their adoption by the Ancient Romans in the 4th century Anno Domini, BC. Arch-like structures can be horizontal, like an arch dam that withstands the horizontal hydrostatic pressure load. Arches are usually used as supports for many types of Vault (architecture), vaults, with the barrel vault in particular being a continuous arch.
