      Why a Fabric Structures ?


      A tensile fabric walkway will allow you to combine practicality with beauty. Your walkway will be as much a feature as it is a solution for sheltering foot traffic. Inspired by nature, fabric tensile canopies add a beautiful organic 3D form whilst still complimenting adjacent buildings

      The significant cost saving is the reduction in installation time required, as the support structure and fabric ancon is pre-fabricated and assembled on site.

      Tensile fabric shapes breathe life and excitement into a building by blending steel construction with organic forms. Tensile fabric structures provide shade and weather protection using low maintenance materials, reducing UV transmission and controlling solar gain.

      Choice of Fabrics


      The choice of fabric is often influenced by the structural strength of the building. Even a small tensile canopy can impart significant loads. The use of new lycra materials can resolve this problem as it can stretch into seemingly impossible forms with the minimum of effort

      Internal fabrics are available in a wide range of colours depending on the type of fabric chosen. Please discuss your requirements further with your Account Manager.

      Features


      •  Unique building medium
      •  Lightweight and flexible - fabric interacts with and expresses natural forces
      •  Tensile fabric structures are an environmentally sensitive medium
      •  Tension is the most efficient way of using any material, it utilises the material at maximum efficiency rather than just the material at the extremes of the cross sectional form, as in bending and compression loads
      •  Fabric structures have higher strength/weight ratio than concrete or steel
      •  Most fabrics can be recycled
      •  A fabric structure can be designed for almost any condition, heavier fabrics and more 3 dimensional forms will cope with extreme wind and snow loads.

  • Benefits


      Various types of Ancon enterprises in the force analysis, design construction, production and installation are very different in degree of difficulty, applications are not the same, but they have the following common characteristics:

      1• Light weight


      Total in the construction of large public construction projects, with a good performance and low cost. In large span structures using Ancon enterprisesthan the traditional structure of light one or a few orders of magnitude, and the weight per unit area and the cost of the structure will not significantly increase with the span increased.

      2 • Sleek, rich flavor of the times


      Ancon enterprises breaks through the traditional architectural structure, easy to be molded into shapes, and colors rich in easy to form under the lights with the night scene, giving people the enjoyment of modern India. Also, because of its advanced technology, ancon enterprises, known as modern architecture, high-tech, 21st century buildings

      3 • Reduce energy consumption


      Better self-translucent Ancon materials, the transmittance rate of 7% ~ 20% or so, make full use of natural light during the day without the use of artificial lighting, fully able to meet the needs of a variety of sports competitions and other activities; film material refractive index of light 70% or more, in the sunlight, the room to form a soft astigmatism, gives a comfortable, dreamy feeling.

      4 • Limits of construction period


      Diaphragm cut production, cable and steel structure, etc. are all produced within the factory may be lower or structures of reinforced concrete structures such as at the same time, at the construction site is just cable, steel and ancon positioning and installation of tensioned connections process and is therefore in the field of construction and installation of more civilized, rapid fast

      5 • Significant economic benefit


      Although the Ancon enterprisesis an investment project is slightly larger, but because of the structure of routine maintenance costs of such a very small (called "maintenance-free structure"), in the long run, the economic effect is very obvious. Such a structure, if used in large-span buildings, there are more prominent price advantage. The economic advantages of cable-Ancon enterprises and space are proportional to the span and technical difficulty.

      6 • Safe and reliable


      Because of its light weight, better seismic performance; Ancon enterprisesis a flexible architecture that can tolerate large displacement, the overall collapse is not easy; and ancon materials are generally flame-retardant materials, are not easy to cause a fire.

      7 • Easily detachable structure, easy to transport, can be used as roving performances, exhibitions, etc.


      Such as the India a company designed the music Punta designed by a company from Delhi covering an area of more than 300 square meters, its removal and installation of only using less than 6 hours.

      8 • Widely used


      From the climatic conditions of view, it applies to delhi from such a vast area; from the scale, it can be as small as a single person tents, garden piece, large enough to cover the tens of thousands, hundreds of thousands of square meters of buildings. Some people even had envisaged coverage of a small town to realize man-made nature.

      9 • Art


      Give full play to the architect's imagination, but also reflects the beauty of the structure.

      10 • Economy


      Since the ancon has a certain transmission rate, during the day can reduce the light intensity and time, can be good energy conservation.At the same time the formation of night-time lights transmission gorgeous landscape can achieve a very good advertising effectiveness.

      11• Large-span


      Ancon enterprisescan be radically overcome the traditional structures in large-span (no support) to achieve the architectural difficulties can create a huge block of non-visual space, more space efficient use of space.

      12 • Self-cleaning of


      Ancon building ancon with a protective coating will enable the building has a good self-cleaning effect, while ensuring that the service life of buildings.

  • Tensile


      Tensile Structures


      Tension roofs or canopies are those in which every part of the structure is loaded only in tension, with no requirement to resist compression or bending forces.

      Take the example of a stick; it will break under compression or bending loads, long before it would be pulled apart by tension. Tension loads maximise the load capacity of materials, or to put it another way, requires the least material. True tensile fabric structures are those in which every part of the fabric is in tension. The fundamental rule for stability is that, a tensioned fabric structure must curve equally in opposite directions; this gives the canopy its 3-dimensional stability.

      This is often referred to as 'double curvature' or an 'anticlastic form' and mathematically it is known as a hyperbolic paraboloid. A proportion of 4:1 between the horizontal span and the vertical articulation is desirable. The more irregular and the flatter the form is, the more we need to load the material to stabilise the shape. This loading or tension, which we have pre-engineered, is called pre-tension or pre stress. Pre-tension is the most efficient way of resisting live loads such as snow, wind etc. A tensile fabric structure, once it is tensioned, can take a large amount of applied weight and the fabric is extraordinarily tight. If something is thrown onto the fabric, it will bounce off. These imposed loads or ‘live loads’ are therefore appropriate when the designer wishes to use the minimum amount of material for either functional or aesthetic reason

      Main uses for internal tensiles are:

      •  Sculptural featuress
      •  Reduce solar glare and heat gain in atria
      •  Internal ceilings to mask unsightly roofs
      •  Internal screens and partitioning
      •  Tensiles for luminaires and lighting schemes
      •  Signage and branding
       

      Fabric Types


      External fabrics


       All types of fabric can be used internally if fire retardant, most commonly used is hybrid fabric such as PVC coated glass cloth.

      Internal fabrics


      All types of fabric can be used if suitably fire retardant. The most commonly used is PVC coated glass cloth due to its easy maintenance and very good fire resistance. Untreated cotton can be used which will burn out in a flash and will not drop hot plastics on anyone below. Lycra materials can be used for awkward or ad-hoc shapes.

  • Design and Build



      The design and build process typically begins with a concept generated by an architect. The architect will consider, among other things, the general shape they would like to see the canopy take, the area to be covered and the purpose of the structure.

      These thoughts may take the form of a very basic sketch, with or without a written brief to a detailed Computer Aided Design (CAD) drawing. We will have a look at what the client is trying to achieve and have in depth discussions regarding their vision for the project. Subsequently, we will provide an initial concept design based on this feedback as well as our own knowledge of the practical considerations to build the structure.

      Dialogue flows freely at this point in the process with the overall goal being to design a beautifully practical structure which can be built in the specified location to budget. This process takes as long as necessary to satisfy all parties.
