D E TA N R O D S Y S T E M S DETAN a creative design element In this project DETAN was purposely applied as a visual, creative design element. DETAN Rod Systems are engineered not only to ensure safe and reliable structural bracing, but also to accentuate the aesthetic elegance of an architectural design. Project: Manchester Civil Justice Centre, UK 4
D E TA N R O D S Y S T E M S DETAN a structural component with an aesthetic appearance DETAN Rod Systems provide reliable structural support and help the architect to bring to life visually pleasing, lightweight structures. DETAN Rod Systems consist of rods and a comprehensive range of matching accessories such as fork ends, anchor disks, cross couplers, and more. User friendly, DETAN Rod Systems can be easily adjusted for length with hidden threads at the fork connections. When used with the matching coupler, DETAN Rod Systems allow for an even greater construction tolerance range. Project: Yale University Cancer Hospital, CT, US 5
Quality Characteristics DETAN Rod Systems: Advantages at a Glance Corrosion protection Carbon steel DETAN Rod Systems offer high quality finishes and seals to protect against corrosion. Threaded plug Internal thread coated Seals (standard) hot-dip galvanized (brushed) hot-dip galvanized Reliable and durable Tension rods are completely hot-dip galvanized after the manufacturing process to provide the best protection with no danger of hydrogen embrittlement Rods have a clean and even, flat finish with no runs or flaking zinc Neat milled wrench flats are provided for reliable rod tightening and simple length adjustment Forks and locking nuts are hot dip galvanized Internal threads are also coated Seals are provided as a standard for rods 16 mm (5/8 ) diameter and higher to protect threads from humidity and contamination Economic and time saving Minimal assembly work on site No danger of incorrect assembly Rods arrive already adjusted to designed system length (with easy ± length adjustment, if required) All components are checked before delivery to site Sealing DETAN Systems Plug Seal set (fv,wb) Flat seal Round seal Fork end Locking nut Tension rod All fork ends are delivered with a plug installed to the open end of the thread for the rod connection. The plugs are color-coded according to the thread direction. Yellow = right-hand thread. Blue = left-hand thread. Carbon steel DETAN system diameters in the range M16 (5/8 ) M95 (3 ¾ ) are provided with special seals to provide corrosion protection to the threaded areas of the system. We recommend that a permanent elastic silicone (designed for external use) is applied to the outer edge of the locking nut. This process should be applied to locking nuts located at fork ends and couplers. It is recommended that both the inner and the outer edges of the locking nut are sealed with silicone for system diameters < M16 (5/8 ). 6
Quality Characteristics DETAN Rod Systems: Advantages at a Glance Product delivery labelling Simple and customer-oriented Easy to read product and order-specific information Simple to sort assemblies by item numbers and dimensional information Quick identification and checking on the construction site On customer request: project-specific data, e.g. floor numbers or grid references can be added Component identification Permanent quality control Order and customer specific data (order and item number, rod length, system size) Standard for diameter 16 mm systems and larger Assembly and Safety Notes Maximum deviation: 0.5 Forks must be correctly aligned (Fig. 1) and positioned in the same plane (Fig. 2a) to ensure that the tension system is not subjected to bending. To ensure the rod can be installed, one fork end of the rod must be able to swing into place; this is not always possible (see figure 3b). An anchor disk must be used in this case; this allows correct installation (see figure 3a). Fig. 1 Fig. 2a Fig. 2b Prior to installation all DETAN Rod System components need to be checked for damage. Damaged components must not be used. Fig. 3a Fig. 3b i Installation Instructions can be found at: www.halfenusa.com Products Tension Rod Systems DETAN Installation Instructions 7

System Engineering Important notes System design load capacities are based on a 1.1 factor to yield. Rod yield strength = 460 MPa ( 66,700 psi ), ultimate strength = 650 MPa ( 94,000 psi ) Connecting plates (page 15) are not provided by HALFEN. Stainless steel grade 304 or 316 with a minimum yield of 36 ksi is assumed for the plate dimensions and design loads shown. Conversions between metric and inch plate thicknesses are not exact to take account of commonly available material. Other materials or thicker/thinner connection plates (dimension b) should not be used without consulting HALFEN. For system diameter 12 (1/2 ) and 27 (1-1/8 ) maximum plus tolerance on the connection plate thickness (b) is + 1/64 or 0.4 mm Loads are based on Grade 36 stainless steel. If connecting plates differ from Grade 36, then please contact our office, 1.800.423.9140, and we will provide new load capacities for you. Anchor discs can accommodate up to 8 rod connections.

Product Range Overview: DETAN Compression Rod System Compression Rod To complement the DETAN Tension Rod System, HALFEN also offers matching compression rods. These provide elegant technical and visual solutions for the support of structural compression loads. Compression rods consist of large diameter tubes, which are tapered at each end so that standard DETAN fork connectors can be used. Standard assemblies are provided in carbon steel, and are dimensioned by HALFEN according to the acting compression forces and the span of the rod. Stainless steel compression rods can also be provided on request. The compression rods are delivered unassembled.

DETAN Pretension Unit Features and Application Some DETAN Tension Rods applications require a pretension load to be applied. Normally it is difficult to accurately apply a pretension load to large diameter DETAN Tension Rods using regular wrenches. Thus, hydraulic jacks are often used to apply pretension loads. The DETAN Pretension Unit is a jacking system designed especially for the DETAN System with diameters that range between M30 (1 3/16 ) and M60 (2 3/8 ). The system uses threaded shells to apply the preload thus preventing the damage to rod finishes often associated with using traditional hydraulic systems. Features of the DETAN Pretension Unit System is built especially for the DETAN Rod Systems Extra lightweight aluminum design for easy use Accurate pretension up to 425 kn (95,600 lbs) No electrical power needed Surface damage to the finish of the rods is avoided Calibrated manometer for accurate preload application Additional checks are possible using an optional extensometer (if gauge marks are applied) Functional, simple & robust Available for rent or purchase Application of pretension The photograph to the left shows pressure being applied using the DETAN Pretension Unit. The application of pretension loads at the jobsite should be planned in advance with the HALFEN engineering department, which will assist with the conversion of the preloads to the hydraulic pressures required. Maximum recommended preloads, the matching hydraulic pressure, and the stress values are given in the table on page 18. Adjusting the rod length The pretension is applied via a special coupler located within the length of the rod. While the jacks unload the coupler temporarily, the coupler can easily be tightened to adjust the rod length to match the correct preload. After the adjustment the DETAN Pretension Unit is released and removed so that the full load is transferred to the coupler. Optional checking of pretension The photograph on the far right shows a mechanical extensometer being used to double check the preload by measuring strain in the rod. This device requires gauge marks on the rod surface, but it is a good method for both initial verification and later checks during the structure s life. Just like the DETAN tension unit, this device is simple to use, robust, and needs no external electrical power source.
