The document outlines the specifications for the PFEIFER-Tension Rod System Type 860, emphasizing the importance of precise structural alignment. The system's axes must intersect at a single point, and the connecting plates should be designed according to the bore diameter and material quality. Misalignment should not exceed 0.5° to prevent bending tensions in the connectors.
The Tension Rod System is pre-assembled to facilitate installation. Adjustments are made using spanners, and the system must be aligned to allow pin insertion without bending. Special tools are available upon request. The minimal thread reach must be verified and documented during installation. If the system length exceeds 10 meters, it requires support with round slings to prevent buckling.
The diameter of tension members is determined by the limit tension from structural calculations. The minimum producible length of the tension member must be considered when specifying system length. Additional specifications should be noted in the order form.
According to DIN Standard 18 800, cables are high tensile tension members. Preferred constructions include spiral strands and full locked cables, used in various structural applications such as suspension bridges and cable nets. Strand ropes are used for specific flexible applications.
Approved end terminations include poured anchorings and ferrules, calculated based on the cable system's breaking load. Free cable length between fittings must meet specified multiples of the cable diameter.
Unloaded cables exhibit non-linear load-extension behavior. Pre-stretching is necessary for accurate length prediction under load. The elasticity modulus is measured after repeated loading cycles to ensure reproducible extension properties. Factors such as temperature and initial load conditions are considered during cable cutting.
Unloaded cables exhibit non-linear load/elongation behavior. To ensure accurate length comparison, cables must be prestretched and measured under preload. The modulus of elasticity is determined as a secant for load increase after cyclic loading. Accurate cutting requires consideration of ambient temperature, settling of the pouring cone, additional elongation from clamps, and cable creep.
To reduce manufacturing tolerances, cables are prestretched and marked under preload. Temperature differences during confectioning are considered. Settling of the pouring cone is accounted for in calculations. Additional elongation from clamps is also considered. Cable creep is factored into production, with cables made shorter by Ek=0.35‰.
Corrosion protection is crucial for safety. It includes constructive measures on structures, protection of individual wires, cable interiors, and surfaces. Galvanized wires and GALFAN coated wires provide effective protection. Full locked cables have inner fillings to minimize surface escape. Compatibility of inner fillings with future corrosion protection must be ensured.
Cables are often coated with GALFAN, which provides effective corrosion protection for non-alloyed steel wires. In industrial atmospheres, the erosion rate of this coating is significantly lower than traditional galvanizing. In Germany, most areas fall under corrosion categories C2 and C3, with an average zinc abrasion rate of 1µm per year. Additional coatings may not be necessary for GALFAN-coated cables, but options are available for aesthetic purposes.
Cable sockets are typically hot-dip galvanized, while fittings are zinc-sprayed. Threads at end terminations are delivered bare but can be zinc/nickel-coated for enhanced protection. Duplex systems combining galvanizing and coating can extend protection and meet color requirements.
Stainless steel cables are made from materials like 1.4401 or 1.4436, with varying corrosion resistance classes. These cables are suitable for structures with moderate environmental stresses and are polished for a shiny finish.
Fire protection systems are generally unnecessary for cables, as they do not increase fire load and are often distant from fire sources. Critical temperatures for cable components must not be exceeded to maintain load-bearing capabilities. In Germany, building regulations must be followed, and specific fire protection systems may be required in certain cases.
Cables are tensioned during or after installation using hydraulic systems. Tensioning forces should prevent slack cables under adverse load conditions. The document provides examples of cable tensioning and the effects of external forces on cable systems.
The document includes examples for determining cable size under uniform load conditions, considering factors like load distribution, safety factors, and cable sag. These calculations are essential for ensuring structural integrity and performance.
The materials used are in accordance with Technical Approval ETA-11/0160. The document covers various types of spiral strands and fittings, including swaged fittings with threads, closed swaged fittings, and open spelter sockets.
The primary application is for spiral strands used in cable structures.
The document lists different types of fittings and cables, such as PE and PG types, with detailed dimensions and weights for each size. For example, PE types range from PE 3 to PE 100, with specifications for dimensions like take-up, total weight, and swaging details.
Various corrosion protection methods are mentioned, including hot dip galvanizing and GALFAN coating, with specific standards like DIN EN ISO 1461 and DIN 50979.
The modulus of elasticity is specified as 160 ± 10 kN/mm², with a tolerance of +3% for strand diameters.
The document notes that technical modifications are subject to change, and larger or intermediate dimensions are available upon request.
Several tables provide detailed specifications for different components, including dimensions, weights, and mechanical properties. For instance, the spiral strand table lists characteristic breaking loads, limit tensions, and metallic cross-sections for various sizes.
The document references standards such as DIN EN 12385 and ASCE 19-96 for construction and safety calculations.

The sockets are suitable for use with full locked cables and spiral strands in various cable structures. Specific types are designed for use with spherical nuts and discs, and fork connectors.
Technical modifications are reserved, and dimensions are provided without corrosion protection. The document emphasizes that bigger dimensions can be requested if needed.
