Dextra recently released an update of all its rebar coupler tools to upgrade to latest version of Tekla.
New Tekla version now allows clear visualization of threaded bar ends, allowing to see the extended threads for first phase rebar for example.
Tekla attributes are available to download from Dextra website.

新しいシャンプレーン橋は、ケベック州 (カナダ) のモントリオールの南東入口にあるセントローレンス川にかかる長さ 3 km の橋です。
The Champlain Bridge is one of the busiest bridges in Canada and plays an important economical role for its city as it is part of the main itinerary to the United States, accessible 60-km South.
For this project, Dextra is supplying its Rolltec メカニカル鉄筋スプライシング system, in both Carbon Steel and Stainless Steel versions. ロールテック is a certified system by the Department of Transportation of the State of Quebec.
This year again, Dextra lined up 2 teams of 12 runners at Peak24 race in Hong Kong! The teams were featuring a mix of Dextra Guangzhou and Dextra Hong Kong staff, pushing together their limits for the good cause and in an incredible atmosphere!
Peak 24 Race is a charity race aiming to raise awareness about slavery and human trafficking problem in the world, and especially in Asia. Funds raised by Peak24 will be donated to the 24 Hour Race, a Hong Kong-founded & international youth charity which inspires students in five countries to join the movement to eradicate modern slavery. The profits raised from us will directly benefit the expansion of the 24 Hour Race movement.
In the United Arab Emirates, Dextra recently delivered a new Oil and Gas project. Dextra tension rods have been used for the support of structure supporting very large liquid gas tanks.
For this application, Dextra engineered, manufactured and delivered bar assemblies based on Carbon Steel bars Gr.355 of diameter Ø120mm. Each テンションバー system is composed of two segments spliced at the lower half of the assembly. The system is mounted onto gusset plates thanks to their fork ends, which can be connected to the structure in just a few minutes by simply sliding in a pin in the middle of the fork.
For length adjustment and tightening, turnbuckes, positionned at the lower half of each tendon, are simply rotated to bring bar segments closer to each other and tension the overall system.
リヤド メトロは、サウジアラビアのリヤドで建設中の大規模な都市交通システム プロジェクトです。このプロジェクトでは、6 つの交通路線に沿って 85 の駅が建設され、鉄道の総延長は 176 km になります。このシステムは、2018 年の開業時には少なくとも 1 日当たり 100 万人の乗客にサービスを提供すると予想されています。
For this large infrastructure project, Dextra Middle East has been involved on various stations and packages.
Before proceeding with general construction works, during early excavation phase, it is required to anchor retaining walls back into the stable ground in order to prevent any wall displacement. This will allow to keep excavating in a safe environment.
For that purpose, Dextra supplied steel ground anchors installed through retaining wall. Each system is based on a high-tensile fully threaded bar, coming with nut and plate, and grouted to provide bonding with the soil.
Bartec 鉄筋カプラー were supplied for the works in the stations. Couplers were used for slabs, column and wall connections. A typicall application on this project is to cast rebar couplers in the concrete with reinforcement, and then proceed with second phase bar connection at a later stage.
Unitec bolted couplers can have also been use on various parts of the project. Typically ユニテック is used when overlap is planned but lapping length appear to be too short to perform a safe splice. In that case Unitec provides a convenient and full performance connection.
Dextra supplied contractor Italian-Thai with テンションバー to support the roof structure of the expansion of BITEC, a leading exhibition and convention center in central Bangkok. Installation has successfully be completed in 2016!
In total, Dextra delivered 298 assemblies in various diameters, each composed of multiple bars connected with couplers and turnbuckles and anchored to the structure with fork ends, with total assembly lengths in several cases exceeding 50 meters long (average 33 meters).
このような大きな構造物の場合、 テンションバー offer a number of advantages compared to other “tensioning” solutions: lower elongation under loads, lower post tensioning forces required, better resistance to corrosion, reduced long terms relaxation and reduced maintenance and surveillance costs.
2017 is upon us and all the Dextra team wishes you a wonderful and prosperous year ahead, and a lot of succesful projects too!
What better way to start the year than making sure those projects will be will built on the strongest bases possible? For that we got you covered!
Dextra recently updated its Ground Engineering range documentation, featuring all our ground anchor solutions. Our unique range covers both steel and FRP (Fiber Reinforced Polymer) solutions. This unique mix will cover all your possible anchoring challenges, in all soil conditions, from permanent to temporary applications.
For precabricated cages used in foundation piling, Dextra recommends the use of 2 distinct solutions that will speed up and ease installation on site: optimal performance, higher productivity, safer operations.
Reinforcement >> Dextra coupler solutions are designed to allow the reconnection of prefabricated cages safely and in a minimum time.
CSL (Crosshole Sonic Logging) >> For Cross-Sonic Logging tubes (used in foundations testing), Sonitec will allow fast reconnection of the tubes without welding.
In Paris, the expansion of Line 14 is part of the Grand Paris Express urban transportation plan. The fast subway line’s expansion will soon cut through Paris to go all the way North to Saint Ouen. Dextra supplied more than 70,000 Fortec couplers used in the stations of Orsay and Pont Cardinet.
In Rennes, Western France, Dextra is successfully delivering Fortec and Rolltec rebar couplers in all four packages constituting makingthe 15 stations and 12.6 kilometers (part elevated, part underground) of the new Line B of the Rennes subway network. Couplers are used in various locations such as retrieval shaft, stations and trenches between stations.
