Tension bars for the suspension of the BITEC’s roof structure (exhibition center expansion project), Bangkok, Thailand


About us Established since 1983, Dextra Manufacturing is a leading manufacturer and distributor of engineered construction products

Dextra has developed for the past fifteen years a comprehensive range of high-performance bar systems made of steel and composite materials suitable for a variety of applications in ground anchoring, concrete tensioning and roof and faรงade support. The combination of our in-house engineering expertise and design capability with modern manufacturing facilities has

Engineering & BIM support

allowed us to participate in the supply of very large construction projects such as Suvarnabhumi Airport in Bangkok (2,000 tons of tension bars) or Boubiyan Seaport (6,000 Tons of Tie rods and accessories). Thanks to our ISO and ASME quality certifications, we are able to control and maintain a high level of quality in all our bar components and systems and guarantee full compliance with the project specifications and customer satisfaction from design stage to delivery and installation.

About our range

Typical applications

Tie Rods are used in port and harbour construction to anchor waterfront structures.. Dextra’s unique range covers various steel grades from 355 to 700 N/mm2 in yield strength, and thread diameters from M42 to M162. Several articulated joints such as swivel plates, captive nuts and ball cage systems can be used to accommodate the project requirements. Our anchorages are compatible with any sheet piles profile, combi walls or concrete diaphragm walls.

• Harbours • Wharves

For projects using sheet piles, Dextra can also design and prefabricate waling beam systems with waling bolts to provide a complete anchoring system which will ensure full compatibility and consistency with our tie rods systems.

Architectural bar systems

Futsal Arena,Bangkok, Thailand


Tension bars are typically acting as bracing or suspenders and provide the benefits of high strength, length adjustment and post-tensioning capability. Being most of the time visible and selected for large architectural structures, they need to be strong but also aesthetic. Compression struts complement the Dextra range of roof supporting systems when structural members are required to take compression loads. Featuring a wide range of sizes and accessories in various steel grades and in both carbon and stainless steel with various finishes, Dextra tension bars and compression struts meet the engineering and design requirements of consultants and architects alike.

Typical applications ●

Roof support systems

Canopies roof support systems

Truss bracing systems

Hanging floors

Road and pedestrian bridges

Temporary stays and braces

CAD & BIM Architectural bar structures are often complex and multidimensional. Design of realistic structures is key to assess how your project will look like and be installed. Dextra supports designers with automated drawing components for AutoCAD (2D) and Trimble Tekla Structure (3D). www.dextragroup.com

About our range


Carbon steel tension bars Central Salaya department store, Nakhon Pathom, Thailand

About our carbon steel range

Design references BS EN 1993 (Eurocode 3)

• Available in high-grade steel, allowing the use of smaller bar diameters to achieve the same tension capacity, which in turn makes site installation both quicker and easier. In situ length adjustment can be achieved by rotation of the bar into the forks and/or at each turnbuckle along the tendon. Turnbuckles also allow for the application of a preload, making for example self-weight sagging corrections easier.

A pair of Fork and Spade form an articulation joint. Forks and spades are connected to gusset plates.

Couplers

Couplers are used to connect standard length bars to achieve a longer required length.

Turnbuckles

Turnbuckles are used to connect and adjust the bar to achieve the required length and remove sagging.

Cross Turnbuckles

Cross-turnbuckles allow two tendons to cross each other in the same plan.

Lock covers

Lock covers are used to cover the exposed thread of the bar.

About our stainless steel range When the requirements for aesthetics or corrosion protection are particularly high, stainless steel tension bars are the perfect solution.

Product features • • • • •

Available in stainless steel grade S460. Thread diameter range M16 to M108. Rolled threads. Minimum Elongation: 25%. Impact strength: 100 kV (J) at 20°C.

Surface finish Two surface finishes are available: satin finish and mirror finish. If not specified Dextra will consider Satin finish.

Product features • Struts are available in two alternative designs: • Architectural • • • •

(with long neck and smoother lines). • Non-architectural. Carbon steel tube (Circular Hollow Section) range from 42mm to 356mm. Thread diameter range from M16 to M113. Length adjustment of the assembly possible at each fork end. Minimum Elongation. ›› Gr 355 21% ›› Gr 460 21% Impact strength 27 J at -20°C.

Non-Architectural strut

Architectural strut

Surface finish Compression struts can either be delivered painted or galvanized. If required, they can also be delivered nonpainted (plain black steel surface).

Model selection CHS (circular hollow section) compression struts range from M16 to M113 and are available in grade 355 and 460. The total compression capacity is limited by the resitance to buckling (which depends on the size of the CHS and pin-to-pin length). Please refer to the technical datasheet available on dextragroup.com for more information about strut selection. For larger load or span custom length can be accomodated.

About our range

Design references

Post-Tensioning bars are used for permanent works such as connecting various segments of bridge structures, shear keys for seismic resistance at the connection of segments or girders and piers, and reinforcement of piers that are subject to horizontal pre-stressing forces.

• •

AASHTO Eurocode 2

They are also used for temporary works such as anchoring of temporary steel frame supports, lifting bars for segment launching trusses, and stitching bridge segments. These bars need to have sufficient strength properties to carry the heavy loads of structures and pre-loading to balance the external loads structures are subjected to at a later stage.

Typical applications ● ● ● ● ● ● ● ● ● ●

Post-tensioning of concrete structures. Temporary bracing / Temporary post-tensioning. Heavy lifting. Seismic restrainer system. Hold down for steel structure, wind turbine. Structural steel frame ties. Bridge segment connections. Bridge segment continuity tendons. Pre-stressed concrete. Pile-testing.

Fully threaded bar system

The services of a fully dedicated design team are available to provide engineering support to our customers.

Smooth bar system

Our post-tensioning range features both fully-threaded bars and smooth bars, with a full range of accessories.

Corrosion protection Various corrosion protection are available depending on whether tendon is temporary permanent, bounded, unbounded, with or without free length. Protection is usually achieved with a combination of heat shrink, grease, paint and/ or grout. The smooth bars for shear key applications are normally supplied in a HDPE tube injected with grease and specialy designed accessories. | w w w. d e x t r a g r o u p . c o m | DEXTRA | 1 7

Dextra smooth bar systems in action For the new coastal elevated highway Nouvelle Route du Littoral in La RĂŠunion Island, Dextra bar systems (threaded bars, nuts and plates) were used in order to provide lifting points in the base of bridge piles. Each of the M64 bar set was tensioned prior to lifting to perform at loads up to 200 tons. More than 1,500 bar systems Grade 930/1080 were used for this project.
