New Caloundra Light
New Caloundra Light, also known as New Caloundra Head Light, is an inactive lighthouse located in Caloundra on the Sunshine Coast in South East Queensland, Australia. It stands on Canberra Terrace near downtown Caloundra. The lighthouse was active from 1968 to 1992. It has a unique design resembling an airport control tower, the only surviving example of a lighthouse of this design in Australia. History Old Caloundra Light had stood on Canberra Terrace since its construction in 1896, marking the entrance to the North West Channel, a deep water channel into Moreton Bay and the Port of Brisbane. Changes in the shipping industry in the 1960s caused an increase in large container ships, which made the channel even more important. In May 1966 permission was granted for the construction of a modern structure comprising a combined lighthouse, signal station and radar station. The New Caloundra Light was erected in 1967, and was the second of a group of seven concrete towers erected b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old Caloundra Light
Old Caloundra Light, also known as Old Caloundra Head Light or Cape Caloundra Light, is an inactive lighthouse located in Caloundra on the Sunshine Coast in South East Queensland, Australia. It is the oldest surviving building in Caloundra. The lighthouse was active between 1896 and 1968. The tower was relocated twice. In 1970 it was relocated from its original location to Woorim Park in Caloundra, and in 1999 it was returned to its original site on Canberra Terrace near downtown Caloundra, where it stands today. History Operation The need for a lighthouse at Caloundra Head arose in 1879 with the sounding of the North West Channel, a deep water channel into Moreton Bay and the Port of Brisbane, the principal port of Queensland. The channel went from Caloundra Head along the eastern shore of Bribie Island. Although the channel became the most used entry channel into the port, it was only lit in 1896, when a pair of mobile leading lights were established on Bribie Island, the Cal ...

Sealed Beam
A parabolic aluminized reflector lamp (PAR lamp or simply PAR) is a type of electric lamp that is widely used in commercial, residential, and transportation illumination. It produces a highly directional beam. Usage includes theatrical lighting, locomotive headlamps, aircraft landing lights, and residential and commercial recessed lights ("cans" in the United States). Many PAR lamps are of the sealed beam variety, with a parabolic reflector, one or more filaments, and a glass or plastic lens sealed permanently together as a unit. Originally introduced for road vehicle headlamp service, sealed beams have since been applied elsewhere. Halogen sealed beam lamps incorporate a halogen lamp within a quartz or hard glass envelope. Construction A PAR lamp consists of a light source, with lens and a parabolic reflector with a smooth aluminium surface determining the spread of the beam. The most common sealed beam type combines these three elements into an integral unit. The light ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Window Sill
A windowsill (also written window sill or window-sill, and less frequently in British English, cill) is the horizontal structure or surface at the bottom of a window. Window sills serve to structurally support and hold the window in place. The exterior portion of a window sill provides a mechanism for shedding rainwater away from the wall at the window opening. Therefore, window sills are usually inclined slightly downward away from the window and wall, and often extend past the exterior face of the wall, so the water will drip off rather than run down the wall. Some windowsills are made of natural stone, cast stone, concrete, tile, or other non-porous materials to further increase their water resistance. Windows may not have a structural sill or the sill may not be sufficiently weather resistant. In these cases, a strip of waterproof and weather resistant material (steel, vinyl, PVC) called a sill pan may be used to protect the wall and shed the water. Like the sill, a sill p ...

Fibre Cement
Fibre cement is a composite building and construction material, used mainly in roofing and facade products because of its strength and durability. One common use is in fiber cement siding on buildings. Material description The term "cement" originates from the Latin word "''Caementum''", which signifies chopped stone. Cement describes a substance which will react chemically with water and develop into a material as hard as stone. In fibre cement there is a fibre reinforcement, which contributes to making the fibre-cement material even stronger. Together with a carefully planned production process, fibre cement makes it possible to develop strong and long lasting construction materials. Today fibre cement is considered as a material physically suited for construction products such as cladding and roofing. It is primarily due to its function, performance and commercial value. Fibre cement flat sheet classified, by accredited laboratories, as Category A according to BS EN 12467:20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pebbledash
Roughcast or pebbledash is a coarse plaster surface used on outside walls that consists of lime and sometimes cement mixed with sand, small gravel and often pebbles or shells. The materials are mixed into a slurry and are then thrown at the working surface with a trowel or scoop. The idea is to maintain an even spread, free from lumps, ridges or runs and without missing any background. Roughcasting incorporates the stones in the mix, whereas pebbledashing adds them on top. According to the ''Encyclopædia Britannica'' Eleventh Edition (1910–1911), roughcast had been a widespread exterior coating given to the walls of common dwellings and outbuildings, but it was then frequently employed for decorative effect on country houses, especially those built using timber framing (half timber). Variety can be obtained on the surface of the wall by small pebbles of different colours, and in the Tudor period fragments of glass were sometimes embedded. Though it is an occasional home-de ...

Balustrade
A baluster is an upright support, often a vertical moulded shaft, square, or lathe-turned form found in stairways, parapets, and other architectural features. In furniture construction it is known as a spindle. Common materials used in its construction are wood, stone, and less frequently metal and ceramic. A group of balusters supporting a handrail, coping, or ornamental detail are known as a balustrade. The term baluster shaft is used to describe forms such as a candlestick, upright furniture support, and the stem of a brass chandelier. The term banister (also bannister) refers to a baluster or to the system of balusters and handrail of a stairway. It may be used to include its supporting structures, such as a supporting newel post. Etymology According to the ''Oxford English Dictionary'', "baluster" is derived through the french: balustre, from it, balaustro, from ''balaustra'', "pomegranate flower" rom a resemblance to the swelling form of the half-open flower (''illus ...

Reinforced Concrete
Reinforced concrete (RC), also called reinforced cement concrete (RCC) and ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars ( rebar) and is usually embedded passively in the concrete before the concrete sets. However, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion. Description Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cantilever
A cantilever is a rigid structural element that extends horizontally and is supported at only one end. Typically it extends from a flat vertical surface such as a wall, to which it must be firmly attached. Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab. When subjected to a structural load at its far, unsupported end, the cantilever carries the load to the support where it applies a shear stress and a bending moment. Cantilever construction allows overhanging structures without additional support. In bridges, towers, and buildings Cantilevers are widely found in construction, notably in cantilever bridges and balconies (see corbel). In cantilever bridges, the cantilevers are usually built as pairs, with each cantilever used to support one end of a central section. The Forth Bridge in Scotland is an example of a cantilever truss bridge. A cantilever in a traditionally timber framed building is called a jetty or forebay. In the southe ...

Handrail
A handrail is a rail that is designed to be grasped by the hand so as to provide safety or support. In Britain, handrails are referred to as banisters. Handrails are usually used to provide support for body or to hold clothings in a bathroom or similar areas. Handrails are commonly used while ascending or descending stairways and escalators in order to prevent injurious falls or to hold necessities. Handrails are typically supported by balusters or attached to walls. Similar items not covered in this article include bathroom handrails—which help to prevent falls on slippery, wet floors—other grab bars, used, for instance, in ships' galleys, and barres, which serve as training aids for ballet dancers. Guard rails and balustrades line drop-offs and other dangerous areas, keeping people and vehicles out. British specifications British Standard and British Standard Code of Practice are harmonized to European Normal (EN) series. Handrail height is set between . US speci ...

Lytton, Queensland
Lytton is an outer riverside suburb in the City of Brisbane, Queensland, Australia. In the , Lytton had a population of 6 people. The historical region was a significant naval base after the establishment of Fort Lytton between 1880 and 1881. The Fort safeguarded the city and shipping routes from hostile invasions during the colonial period as Brisbane was close to the French naval garrison at Nouméa. Geography The suburb is bounded by the Brisbane River to the north-west. It is east of the Brisbane CBD, but travel by the railway or road is considerably longer. Lytton Hill is in the north-east of the suburb () above sea level. Clunie Flats is a pan in the west of the suburb (). History A pilot station and a village were established at Lytton in 1859. It was most likely named after Edward Bulwer-Lytton (1803–73) who was the Colonial Secretary of State in 1858–59. It would be two years before a road was surveyed from Norman Creek. A telegraph line was run from Bris ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battery (electricity)
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons that will flow through an external electric circuit to the positive terminal. When a battery is connected to an external electric load, a redox reaction converts high-energy reactants to lower-energy products, and the free-energy difference is delivered to the external circuit as electrical energy. Historically the term "battery" specifically referred to a device composed of multiple cells; however, the usage has evolved to include devices composed of a single cell. Primary (single-use or "disposable") batteries are used once and discarded, as the electrode materials are irreversibly changed during discharge; a common example is the alkaline battery used ...

Mains Electricity
Mains electricity or utility power, power grid, domestic power, and wall power, or in some parts of Canada as hydro, is a general-purpose alternating-current (AC) electric power supply. It is the form of electrical power that is delivered to homes and businesses through the electric grid in many parts of the world. People use this electricity to power everyday items—such as domestic appliances, televisions and lamps—by plugging them into a wall outlet. The voltage and frequency of electric power differs between regions. In much of the world, a voltage (nominally) of 230 volts and frequency of 50 Hz is used. In North America, the most common combination is 120 V and a frequency of 60 Hz. Other combinations exist, for example, 230 V at 60 Hz. Travellers' portable appliances may be inoperative or damaged by foreign electrical supplies. Non-interchangeable plugs and sockets in different regions provide some protection from accidental use of appliances ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
