Nathani Heights is a 72-storeys skycrapper in Mumbai. With a total height of 262 meters it is among the 30 tallest building in the city. The construction of the building started in 2012 and will be completed in 2018.

For this project, Dextra supplied its famous Bartec rebar coupler solution. Bartec is the main rebar coupler solutions in India, satisfying all technical requirements even in seismic areas.

As in other highrise building, rebar couplers have been used for large diameter rebar connection in vertical applications such as columns and corewalls (bar to bar vertical connection).

Rebar couplers were also used for slab connections. In that case, the coupler is pre-positionner flush with formwork (allowing climbing formwork to go up). After casting, a threaded rebar is simply screwed inside the coupler to create the starter bar.

Business Garden Bucharest is a modern mixed used class A office complex. It features retail spaces, pairing with commercial and public services on the ground level. The name Business Garden stems from its integrated spacious green area, a garden connecting the buildings with designated recreation spaces. Generous lawn area, pedestrian pathways, and benches with free Wi-Fi are provided to invite the office goers to work or take a refreshing break outside. The complex is LEED Platinum pre-certified. To support the tenant’s everyday life needs of their employees, Business Garden Bucharest’s offices are designed to have efficient layout, built with high quality finishes and sustainable solutions that are in line with LEED Platinum green certifications.

For this project, Dextra was involved in the supply of its Fortec rebar coupler solution. The Fortec solution is made up of a standard rebar coupler that can be utilize as both standard and position splices connecting two rebar ends that have been previously enlarged and threaded. Fortec is especially suitable for seismic environment construction, which is the case of buildings in the Bucharest area.

Fortec couplers have been used to provide superstructure vertical connections. Fortec couplers are relatively compact and can help to reduce the congestion created from rebar lapping. Fortec couplers also provided temporary opening, allowing movement of the workers and equipment around the reinforcement. Before casting, the continuation bars are simply connecting to the couplers, filling the temporary opening gap.

ロンドン ウォール プレイスは、ロンドンにある大規模な 2 タワーのオフィス開発で、歴史的建造物であるローマの城壁の近くに建てられています。

このプロジェクトでは、デエクストラは請負業者のバーン ブラザーズとメイン コンサルタントの WSP に、プレキャスト壁パネルを迅速に設置するための技術ソリューションを提供しました。

コンセプトは、Rolltec スレッド システムで事前に準備された垂直バーの下部にある各パネル補強材に Groutec カプラーを取り付けることでした。このカプラーは、当社の販売代理店ネットワークを通じて英国で入手可能です。

プレキャスト パネルを最終位置で固定した後、鉄筋接続を作成するために、非収縮グラウトがカプラーのキャビティに注入されます。 Groutec は特定のタイプのグラウトに依存しません。むしろ、いくつかの異なるブランドのグラウトを使用することができ、局所的な精練が容易になり、コストを低く抑えることができます。グラウトが所定の強度に達した後、パネル周囲のブレースを取り外します。

プレキャスト パネルを矯正して固定した後、非収縮グラウトを射出によってキャビティに挿入します。 Groutec は設計上、地元で調達できるいくつかのブランドと互換性があるため、Dextra はグラウト材を供給しません。これにより、コストが削減され、プロジェクト管理が容易になります。注入後、プレキャスト パネルの周囲のブレースはわずか 3 日後に取り外すことができます。

プレキャスト パネルに Groutec を使用すると、プレキャスト テクノロジーをすぐに活用できる、時間を節約でき経済的な方法になります。同様のアプリケーションビデオについては、こちらをご確認ください。 プラム・セントラル・ステーションのプロジェクトページ.

Icon Siam complex, located on the right bank of the Chao Phraya river in the West of Bangkok, is a new multipurpose commercial/residential complex consisting of two highrise buildings and a shopping mall. This new massive project aims to give back its glamour to the banks of the Chao Praya river.

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 バーテック rebar couplers and 20,000 Bartec 頭付きバー 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.

Landmark 81 is a new highrise tower project located on the bank of the Saigon river in Ho Chi Minh City. The project is owned by Vietnamese company Vingroup.

The tower, whose construction started end of 2014, is expected to reach the height of 462 meters, a new height record in Vietnam. Landmark 81 will the 11th tallest tower building in the world.

このプロジェクトのために、Dextra は有名な
バーテック solution to contractor Coteccons. Bartec solution has been approved by ARUP, owner’s representative consultant, and MACE International, structural consultant.

In total, 250,000 Bartec couplers will be used for vertical rebar connection in the corewall and columns as well as for horitonzal applications such as corewall-to-beam and corewall-to-slab connections.

The use of rebar couplers allows the climbing ormwork to move its way up unencumbered as well as connect slabs starting bars in a very productive manner. Those technologies combined with state-of-the-art concrete monitoring allow very fast construction cycles as short as 35 hours per floor.

For composite applications (steel columns to beams), Dextra also supplied 20,000 weldables couplers.

Example of weldable Bartec coupler on beam

The fast-paced construction site is supported by three sets of Dextra Bartec equipment, installed directly on site. The equipment is maintained by Dextra and operated by Dextra’s distributor in Vietnam, Lotus Greentech.

Concrete works were completed ahead of schedule early 2018.
