Eaves And Stem
The eaves are the edges of the roof which overhang the face of a wall and, normally, project beyond the side of a building. The eaves form an overhang to throw water clear of the walls and may be highly decorated as part of an architectural style, such as the Chinese dougong bracket systems. Etymology and usage According to the ''Oxford English Dictionary'', ''eaves'' is derived from the Old English (singular), meaning "edge", and consequently forms both the singular and plural of the word. This Old English word is itself of Germanic origin, related to the German dialect ''Obsen'', and also probably to ''over''. The Merriam-Webster dictionary lists the word as ''eave'' but notes that it is "usually used in plural". Function The primary function of the eaves is to keep rain water off the walls and to prevent the ingress of water at the junction where the roof meets the wall. The eaves may also protect a pathway around the building from the rain, prevent erosion of the footi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roof
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.

Purlin
A purlin (or historically purline, purloyne, purling, perling) is a longitudinal, horizontal, structural member in a roof. In traditional timber framing there are three basic types of purlin: purlin plate, principal purlin, and common purlin. Purlins also appear in steel frame construction. Steel purlins may be painted or greased for protection from the environment. Etymology Information on the origin of the term "purlin" is scant. The Oxford Dictionary suggests a French origin, with the earliest quote using a variation of ''purlin'' in 1447, though the accuracy of this claim has been disputed. In wood construction Purlin plate A purlin plate in wood construction is also called an "arcade plate" in European English, "under purlin", and "principal purlin". The term plate means a major, horizontal, supporting timber. Purlin plates are beams which support the mid-span of rafters and are supported by posts. By supporting the rafters they allow longer spans than the rafters alone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Architectural Elements
:''The following outline is an overview and topical guide to architecture:'' Architecture – the process and the product of designing and constructing buildings. Architectural works with a certain indefinable combination of design quality and external circumstances may become cultural symbols and / or be considered works of art. What ''type'' of thing is architecture? Architecture can be described as all of the following: * Academic discipline – focused study in one academic field or profession. A discipline incorporates expertise, people, projects, communities, challenges, studies, inquiry, and research areas that are strongly associated with the given discipline. * Buildings – buildings and similar structures, the product of architecture, are referred to as architecture. * One of the arts – as an art form, architecture is an outlet of human expression, that is usually influenced by culture and which in turn helps to change culture.

Soffit
A soffit is an exterior or interior architectural feature, generally the horizontal, aloft underside of any construction element. Its archetypal form, sometimes incorporating or implying the projection of beams, is the underside of eaves (to connect a retaining wall to projecting edge(s) of the roof). The vertical band at the edge of the roof is called a fascia. Etymology The term ''soffit'' is from it, soffitto, formed as a ceiling; and directly from ''suffictus'' for ''suffixus'', la, suffigere, to fix underneath). Soffits in homes and offices In architecture, soffit is the underside (but not base) of any construction element. Examples include: Under the eaves of a roof In foremost use ''soffit'' is the first definition in the table above. In spatial analysis, it is one of the two necessary planes of any (3-dimensional) optionally built area, eaves, which projects, for such area to be within the building's space. In two-dimensional face analysis it is a discrete f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rainhead
Leader heads or conductor heads are components of a roof drainage system which are known by different names, but they all mean the same. They are funnel-shaped elements, connected in most cases to a gutter, and from there to a downspout. The downspouts take the water run off from the roof that is collected in the gutters to the ground or into a storm water management system. Purpose The purpose of a leader head is to help transfer excess water from the roof onto downspouts, thus preventing the gutters from overflowing and water washing over the walls, which is a common occurrence in areas susceptible to heavy rain cycles. The use of leader heads also offers other benefits to the drainage system. Because the top of the funnel is open, air is constantly introduced into the system and water flows faster through the downspouts. Additionally, some leader heads are designed to receive more than one downspout, or in some cases more than one gutter c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overhang (architecture)
In architecture, an overhang is a protruding structure that may provide protection for lower levels. Overhangs on two sides of Pennsylvania Dutch barns protect doors, windows, and other lower-level structures. Overhangs on all four sides of barns and larger, older farmhouses are common in Swiss architecture. An overhanging eave is the edge of a roof, protruding outwards from the side of the building, generally to provide weather protection. History Overhangs are also common in medieval Indian architecture—especially Mughal architecture of the 16th–18th century, where they are called '' chhajja'', often supported by ornate corbels and also seen in Hindu temple architecture. Later, these were adopted by Indo-Saracenic architecture, which flourished during the British Raj. Extensive overhangs were incorporated in early Buddhist architecture; were seen in early Buddhist temples; and later became part of Tibetan architecture, Chinese architecture, and eventually, traditional Jap ...

Lookout (architecture)
A lookout, lookout rafter or roof outlooker is a wooden joist that extends in cantilever out from the exterior wall (or wall plate) of a building, supporting the roof sheathing and providing a nailing surface for the fascia boards. When not exposed it serves to fasten the finish materials of the eaves The eaves are the edges of the roof which overhang the face of a wall and, normally, project beyond the side of a building.

Gargoyle
In architecture, and specifically Gothic architecture, a gargoyle () is a carved or formed grotesque with a spout designed to convey water from a roof and away from the side of a building, thereby preventing it from running down masonry walls and eroding the mortar between. Architects often used multiple gargoyles on a building to divide the flow of rainwater off the roof to minimize potential damage from rainstorms. A trough is cut in the back of the gargoyle and rainwater typically exits through the open mouth. Gargoyles are usually elongated fantastical animals because their length determines how far water is directed from the wall. When Gothic flying buttresses were used, aqueducts were sometimes cut into the buttress to divert water over the aisle walls. Etymology The term originates from the French ''gargouille,'' which in English is likely to mean "throat" or is otherwise known as the "gullet"; cf. Latin ''gurgulio, gula, gargula'' ("gullet" or "throat") and similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eavesdropping
Eavesdropping is the act of secretly or stealthily listening to the private conversation or communications of others without their consent in order to gather information. Etymology The verb ''eavesdrop'' is a back-formation from the noun ''eavesdropper'' ("a person who eavesdrops"), which was formed from the related noun ''eavesdrop'' ("the dripping of water from the eaves of a house; the ground on which such water falls"). An eavesdropper was someone who would hang from the eave of a building so as to hear what is said within. The PBS documentaries ''Inside the Court of Henry VIII'' (April 8, 2015) and ''Secrets of Henry VIII’s Palace'' (June 30, 2013) include segments that display and discuss "eavedrops", carved wooden figures Henry VIII had built into the eaves (overhanging edges of the beams in the ceiling) of Hampton Court to discourage unwanted gossip or dissension from the King's wishes and rule, to foment paranoia and fear, and demonstrate that everything said there was ...

Eavesdrip
The eavesdrop or eavesdrip is the width of ground around a house or building which receives the rain water dropping from the eaves. By an ancient Anglo-Saxon law Anglo-Saxon law (Old English ''ǣ'', later ''lagu'' "law"; dōm "decree, judgment") is a body of written rules and customs that were in place during the Anglo-Saxon period in England, before the Norman conquest. This body of law, along with early ..., a landowner was forbidden to erect any building at less than two feet from the boundary of his land, and was thus prevented from injuring his neighbour's house or property by the dripping of water from his eaves. The law of Eavesdrip had its equivalent in the Roman stillicidium, which prohibited building up to the very edge of an estate.

Chhajja
A ''chhajja'' is an overhanging eave or roof covering found in Indian architecture. It is characterised with large support brackets with different artistic designs. Variation is also seen in its size depending on the importance of the building on which it features or the choice of the designer. Its function is similar to that of other overhangs or eaves in that it protects and adorns entrances, arches and windows from the outside elements. Some styles of roof can be considered large chhajja as well. History Although there is no conclusive agreement on when the chhajja emerged as an architectural element, it can be traced back to before the rise of the Mughal Empire in India. However, much of its popular use seems to be during this time. The original inspiration of the chhajja and much of the other Indian architectural elements with which it is commonly not seen can be traced back to building design from older periods, such as that of bamboo and thatch village huts that can still ...
