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. [3] In classical Western architecture and construction methods, by Merriam-Webster definition, a lintel is a load-bearing member and is placed over an ...
A jack arch is a structural element in masonry construction that provides support at openings in the masonry. Alternate names are lintel arch, [1] 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.
Ashlar masonry. Stone masonry using dressed (cut) stones is known as ashlar masonry. [4] Trabeated systems. One of the oldest forms of stone construction uses a lintel (beam) laid across stone posts or columns. This method predates Stonehenge, and refined versions were used by the Egyptians, Persians, Greeks, and Romans. [4] Arch masonry.
Rice had worked on the Sydney Opera House, which was a major technical advance in part because of its use of pre-cast concrete masonry beams that were assembled into the pointed-arch superstructure using post-tensioning; this prior use of post-tensioned masonry may have contributed to Rice's use of post-tensioned stone decades later.
In masonry veneer building construction, a shelf angle or masonry support is a steel angle which supports the weight of brick or stone veneer and transfers that weight onto the main structure of the building so that a gap or space can be created beneath to allow building movements to occur.
Precast parking structure showing an interior column, girders, and double-tee structural floors. The two gray circles are covers to close the lifting anchor holes. Precast concrete building components and site amenities are used architecturally as fireplace mantels, cladding, trim products, accessories and curtain walls.
Formwork tables in use at a building site with more complicated structural features. Crane fork or elevator handled: By this approach the tables are limited in size and weight. Typical widths are between 6 and 10 feet (1.8 and 3.0 m), typical lengths are between 12 and 20 feet (3.7 and 6.1 m), though table sizes may vary in size and form.
Concrete has similar thermal properties to masonry products, in that it has a relatively high thermal mass and is a good conductor of heat. In some special cases, the thermal properties of concrete have been employed, for example as a heatsink in nuclear power plants or a thermal buffer in industrial freezers.
