Icon Siam, new heights on Bangkok’s riverside
Double tower project aims to give back its glamour
to the banks of the Chao Phraya
On the right bank of the Chao Phraya river, the Icon Siam complex, consisting of two towers and a shopping mall, is currently reaching for new heights.
The two towers are expected to reach 280m (SuperLux Tower) and 315m (Magnolia Tower) respectively. The Magnolia Tower will thus be slightly taller than the MahaNakhon Tower, Bangkok’s tallest building since 2015.
Dextra is supplying Thai-Obayashi (contractor of the shopping mall structure) and Italian-Thai (contractor 
of both towers) with its Bartec rebar splicing solution.
Dextra engineers performed operator trainings and do preventive maintenance directly on site to guarantee maximum output in thread production.
In total, more than 800,000 Bartec rebar couplers and 20,000 Bartec Headed Bars are being used in foundations and superstructure in the following applications:
L-shaped dowel bars (wall-slab connections)
This is a typical application used in foundation D-Walls to avoid protruding rebar. it is also used in the superstructure to allow the sliding formwork to climb up without any disturbance
Substitution of hooked bars with end anchors
When the wall reinforcement is especially congested, the use of Headed Bars (also called end anchors) allows to anchor the reinforcement in the wall without the need to produce hooks.
Double-ended connection in shear-walls
This solution allows to create a continuity inside the column or wall by bridging two horizontal slabs or beams.
Welded couplers for composite structures
Sometimes it is necessary to start reinforcement from the steel structure. In that case, weldable couplers are the ideal solution: Made of a low-carbon steel, they can be welded easily and allow connection to a threaded rebar.
Riyadh Metro progress
Dextra supplied multiple packages of this new urban transportation system
Riyadh Metro is a massi
ve urban transit system project under construction in the capital of Saudi Arabia
The new transportation system will feature 85 stations, built along 6 lines, for a total rail length of 176km.
It is expected that the system will serve at least 1 million passengers daily at its inauguration in 2018.
For this large infrastructure project, Dextra has been involved in several stations and packages.
Anchoring station perimeter walls
Splicing rebar across station
1/ Ground Anchors
During the excavation phase and before proceeding with the general construction works, the retaining walls of the excavation area need to be anchored to the background. This will prevent any wall displacement and guarantee the safety of operations.
For that purpose, Dextra supplied steel ground anchors installed at the station perimeter. Each system is based on a high-tensile fully threaded bar, coming with nut and plate, and grouted to provide bonding with the soil.
2/ Unitec bolted couplers
Bartec, the leading coupler solution in the Middle East, was used for rebar connection in slabs, columns and wall connections.
Unitec bolted couplers have also been used on various parts of the project. Typically, Unitec is applied when the rebar cannot be threaded and lap lengths are too short for a correct splice.
In such cases Unitec provides a convenient and full performance connection, while only requiring a standard impact wrench to lock the connection
