Fence
A fence is a structure that encloses an area, typically outdoors, and is usually constructed from posts that are connected by boards, wire, rails or netting. A fence differs from a wall in not having a solid foundation along its whole length. Alternatives to fencing include a ditch (sometimes filled with water, forming a moat). Types By function * Agricultural fencing, to keep livestock in and/or predators out * Blast fence, a safety device that redirects the high energy exhaust from a jet engine * Sound barrier or acoustic fencing, to reduce noise pollution * Crowd control barrier * Privacy fencing, to provide privacy and security * Temporary fencing, to provide safety, security, and to direct movement; wherever temporary access control is required, especially on building and construction sites * Perimeter fencing, to prevent trespassing or theft and/or to keep children and pets from wandering away. * Decorative fencing, to enhance the appearance of a property, gar ...

Agricultural Fencing
In agriculture, fences are used to keep animals in or out of an area. They can be made from a wide variety of materials, depending on terrain, location and animals to be confined. Most agricultural fencing averages about high, and in some places, the height and construction of fences designed to hold livestock is mandated by law. A is the strip of land by a fence that is left uncultivated. It may be a hedgerow or a shelterbelt (windbreak) or a refugee for native plants. If not too narrow, it acts as a habitat corridor. History Historically throughout most of the world, domesticated livestock would roam freely and were fenced out of areas, such as gardens or fields of crops, where they were unwanted. Over time, especially where crop agriculture became dominant and population density of both humans and animals was significant, livestock owners were made to fence their animals in. The earliest fences were made of available materials, usually stone or wood, and these materia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snow Fence
A snow fence, similar to a sand fence, is a barrier that forces windblown, drifting snow to accumulate in a desired place. They are primarily employed to minimize the amount of snowdrift on roadways and railways. Farmers and ranchers use snow fences to create drifts in basins for a ready supply of water in the spring. Ski resorts also use snow fences in order to increase snow depth in specified areas, or for avalanche control. Description and physical mechanism Temporary snow fences are usually one of two varieties: perforated orange plastic sheeting attached to stakes at regular intervals (the type usually used for construction site fencing or temporary sports field fencing), or a cedar or other lightweight wood strip and wire fence, also attached to metal stakes. A permanent snow fence usually consists of poles with horizontal planks running across them so that they cover just over one-half of the total fence area. The bottom 10% to 15% of the fence should be left open so th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pet Fence
A pet fence or fenceless boundary is an electronic system designed to keep a pet or other domestic animal within a set of predefined boundaries without the use of a physical barrier. A mild electric shock is delivered by an electronic collar if its warning sound is ignored. The system was first invented and patented by Richard Peck in 1973. History The pet fence was created in 1973 by Richard Peck. Peck was a traveling salesman and through his travels, he saw enough dogs hit by cars that it led to him creating the pet fence system. In 1976, salesman John Purtell bought the rights to the pet fence and rebranded it as "Invisible Fence" which offered a different option for pet owners in terms of pet containment. In 1990, Invisible Fence Co became Invisible Fence Inc. Technology A typical invisible fence transmits a radio signal that takes the geometric shape of the area that is enclosed by the system. The pet wears a lightweight collar that emits a sensory cue, such as a warning so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pest-exclusion Fence
280px, Xcluder pest-exclusion fence around perimeter of Maungatautari A pest-exclusion fence is a barrier that is built to exclude certain types of animal pests from an enclosure. This may be to protect plants in horticulture, preserve grassland for grazing animals, separate species carrying diseases ( vector species) from livestock, prevent troublesome species entering roadways, or to protect endemic species in nature reserves. These fences are not necessarily traditional wire barriers, but may also include barriers of sound, or smell. Design techniques Animals can be excluded by a fence's height, depth under the ground and mesh size. It is also important to choose a construction material that cannot be climbed; furthermore, sometimes it is necessary to create a subsurface fencing element to prevent burrowing under the fence.

Perimeter Fencing
Demarcation of a perimeter, when the protection of assets, personnel or buildings is required, is normally affected by the building of a perimeter fence system. The level of protection offered varies according to the threat level to the perimeter. Different types of perimeter fencing include: * Timber fencing * Palisade fencing * Welded wire mesh fence fencing * Chain-link fencing * Rolled mesh fencing * Metal railings Vertical bar fencing has been the most popular form of perimeter security fence since the 1980s. Since the 2000s, welded wire mesh and acoustic barriers have also become popular types of perimeter fence around the world. Vertical bar, acoustic barriers and welded mesh are used in commercial projects and landmarks, in schools, and in airports and transport hubs. In high-security applications, sensors may be attached to the fence that generate alarms when they detect someone cutting, climbing, or lifting the fence fabric. Domestic and residential projects have s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pool Fence
A swimming pool fence is a type of fence placed around swimming pools, to create a passive barrier to restrict the access of small children to the swimming pool. Swimming pool fences must have a self-closing and self-latching gate/s to be compliant to most countries' laws and codes. Swimming pool fences are designed so that young children cannot climb over them or go through them. They are manufactured to strict standards to be sturdy, durable and non-climbable. Most countries design, manufacture and install swimming pool fences to the International Code Councils (ICC) guidelines. Types Swimming pool fences are manufactured in several different types, using a variety of materials. * Aluminum * Steel * Glass * Vinyl/PVC fencing * Mesh They can be slotted to allow visibility or solid for privacy. Swimming pool barrier regulations Countries, states and municipalities within countries have different laws regarding swimming pool fencing laws, ranging from no laws at all to very ...

Temporary Fencing
Temporary fencing is a free standing, self-supporting fence panel. The panels are held together with couplers that interlock panels together making it portable and flexible for a wide range of applications. A common type of temporary fencing is Heras fencing. Fence panels are supported with counter-weighted feet, have a wide variety of accessories including gates, handrails, feet and bracing depending on the application. Fence panels are commonly constructed of either chain link or weld mesh. Temporary fencing is an alternative to its permanent counterpart when a fence is required on an interim basis when needed for storage, public safety or security, crowd control, or theft deterrence. It is also known as construction hoarding when used at construction sites. Other uses for temporary fencing include venue division at large events and public restriction on industrial construction sites, when guardrails are often used. Temporary fencing is also often seen at special outdoor even ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newt Fencing
Newt fencing is a barrier designed to control the movement of great crested newts, other amphibians or reptiles. It can also be called drift fencing or temporary amphibian fencing (TAF). It consists of a low fence of plastic sheeting, buried a short way into the ground and supported by lightweight posts usually made of wood or plastic. It is used to keep animals out of working areas, to keep them inside safe areas of their habitat, to intercept migration routes, or to control their movement to help their capture for translocation. It may be used in conjunction with pitfall traps placed at the foot of the fence. It is most commonly used in connection with building projects, to minimise harm to protected species. Background Legislation The great crested newt (''Triturus cristatus'') is an amphibian native to the United Kingdom but also widespread across Northern Europe. Whilst it is relatively widespread in the UK (in fact the UK hosts one of the great crested newt's most si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Real Property
In English common law, real property, real estate, immovable property or, solely in the US and Canada, realty, is land which is the property of some person and all structures (also called improvements or fixtures) integrated with or affixed to the land, including crops, buildings, machinery, wells, dams, ponds, mines, canals, and roads, among other things. The term is historic, arising from the now-discontinued form of action, which distinguished between real property disputes and personal property disputes. Personal property, or personalty, was, and continues to be, all property that is not real property. In countries with personal ownership of real property, civil law protects the status of real property in real-estate markets, where estate agents work in the market of buying and selling real estate. Scottish civil law calls real property "heritable property", and in French-based law, it is called ''immobilier'' ("immovable property"). Historical background The wor ...

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. Etymology Old English 'roof, ceiling, top, summit; heaven, sk ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stairway
Stairs are a structure designed to bridge a large vertical distance between lower and higher levels by dividing it into smaller vertical distances. This is achieved as a diagonal series of horizontal platforms called steps which enable passage to the other level by stepping from one to another step in turn. Steps are very typically rectangular. Stairs may be straight, round, or may consist of two or more straight pieces connected at angles. Types of stairs include staircases (also called stairways), ladders, and escalators. Some alternatives to stairs are elevators (also called lifts), stairlifts, inclined moving walkways, and ramps. A stairwell is a vertical shaft or opening that contains a staircase. A flight (of stairs) is an inclined part of a staircase consisting of steps (and their lateral supports if supports are separate from steps). Components and terms A ''stair'', or a ''stairstep'', is one step in a flight of stairs.R.E. Putnam and G.E. Carlson, ''Architectural ...

Balcony
A balcony (from it, balcone, "scaffold") is a platform projecting from the wall of a building, supported by columns or console brackets, and enclosed with a balustrade, usually above the ground floor. Types The traditional Maltese balcony is a wooden closed balcony projecting from a wall. By contrast, a Juliet balcony does not protrude out of the building. It is usually part of an upper floor, with a balustrade only at the front, like a small loggia. A modern Juliet balcony often involves a metal barrier placed in front of a high window that can be opened. In the UK, the technical name for one of these was officially changed in August 2020 to a ''Juliet guarding''. Juliet balconies are named after William Shakespeare's Juliet, who, in traditional stagings of the play '' Romeo and Juliet'', is courted by Romeo while she is on her balcony—though the play itself, as written, makes no mention of a balcony, but only of a window at which Juliet appears.
