All components of the system can be supplied in a variety of finishes to provide corrosion resistance and to meet the demanding aesthetic requirements of many architectural applications. The bar used in this system has a minimum yield of 500N/mm2. ✓ CE marked ✓ High load capacity ✓ Carbon steel or stainless steel ✓ Bars from 8mm to 42mm diameter ✓ Choice of finishes ✓ Aesthetically designed forks ✓ Locking nut included as standard ✓ Full adjustment within fork connectors ✓ Visual check of correct installation ✓ Isolation supplied as standard with stainless steel systems Ancon 500 Tension...

and locking nuts can be supplied electropolished, satin-polished or hand polished. The photographs below provide a good indication of the available finishes; actual finishes may differ slightly. Couplers and anchor discs are supplied with a smooth machined finish as standard, and can be satin-polished or hand polished when required. All available finishes and order codes are shown on page 13. Isolation System Isolation material is supplied as standard with the stainless steel system to enable its fixing to a connecting plate of a dissimilar metal. Each stainless steel fork connector is supplied...

Tension and Compression Systems Pin Fork connector PTFE coating (stainless steel system only) Anchor Disc System Components The wide range of components available can be used to create a variety of assemblies, from simple tie bars to complex bracing systems involving several bars joined at one point. Carbon steel forks and locking nuts are zinc plated as standard. Stainless steel forks and locking nuts are electro-polished as standard and can also be supplied satin or hand polished. Each stainless steel fork is supplied with two clear, self-adhesive, PET (polyester) washers to isolate the...

Tie Bars Tie bars have a right-hand thread at one end and a left-hand thread at the other. Flats are pressed into the bar close to each end. These allow the bar to be screwed into the fork connectors and adjustments to be made at any time after assembly. Neither couplers nor turnbuckles will be required for applications using a single bar between two forks. The bar is correctly installed when all threads are hidden within the locking nut. The availability of each size of bar is given on page 11. All bars are cut to a tolerance of ±2mm of the specified length. Carbon steel bars are available...

Tension and Compression Systems Applications Ancon has supplied Tension and Compression Systems to many structures and buildings. The wide range of components can be used to create a variety of assemblies, from simple tie bars to complex bracing systems involving several bars joined at one point. The following applications demonstrate the variety of uses. Timber Construction A combination of timber and steel can use the best properties of each material and achieve a cost-effective and attractive design. Ancon Tension Systems can be connected to timber compression members, and if high loads...

Stainless Steel Systems Stainless steel is used for applications where a maintenance-free life is important or where a high quality polished finish is required. This can be particularly impressive when used in conjunction with large areas of glazing. Cross-Bracing The use of anchor discs or cross couplers form a cross brace, allowing bars to lie in the same plane. This removes the need to offset bars, with the disc or coupler providing an interesting design feature for the panel. Glazed Structures The passage of light is normally a vital consideration in the design of glazed structures. The...

Performance and Dimensions The design resistances include a material factor (ym) of 1.25 against failure. An appropriate partial safety factor (y,) will need to be applied to the characteristic dead, imposed and wind loads. Forks must be correctly aligned, and positioned in the same plane to ensure that bending is not introduced into the tension system. Design Example Characteristic dead load = 30.0kN yf = 1.35 Characteristic imposed load = 22.6kN yf = 1.5 Design load = (30.0 x 1.35) + (22.6 x 1.5) = 74.4kN Use Ancon 500/20 Design Resistance = 79.1kN > 74.4kN Ancon Tension Systems are not...
