ICONSIAM, located on the right bank of the Chao Phraya River in western Bangkok, is a multipurpose commercial and residential complex consisting of two high-rise buildings and a shopping mall. This massive development aims to restore the glamour of the Chao Phraya River’s waterfront.

The two towers are expected to reach heights of 280 meters (SuperLux Tower) and 315 meters (Magnolia Tower), respectively. Upon completion, Magnolia Tower will surpass King Power Mahanakhon Tower, which has been Thailand’s tallest building since 2015.

Dextra is supplying Thai-Obayashi (the contractor for the shopping mall structure) and Italian-Thai (the contractor for both towers) with its Bartec vergalhões solução de emenda.

To ensure maximum efficiency in thread production, Dextra engineers have conducted operator training and provided on-site preventive maintenance.

In total, more than 800,000 Bartec rebar couplers and 20,000 Barras com cabeça are being used in the foundations and superstructure for the following applications:

L-shaped cavilha barras (conexões parede-laje)

This is a typical application used in foundation paredes de diafragma (D-Walls) to avoid protruding rebar. It is also used in the superstructure, allowing the sliding formwork to climb without obstruction.

Substituição de barras com ganchos com Barras com cabeça

Quando a parede reforço está especialmente congestionado, o uso de Barras com cabeça (also called end anchors) allows for anchoring the reforço in the wall without the need for hooks.

Conexão dupla em paredes de cisalhamento

Esta solução permite criar uma continuidade no interior do pilar ou da parede através da ligação de duas lajes ou vigas horizontais.

Acopladores soldados para composto estruturas

Sometimes, it is necessary to start reforço from the steel structure. In such cases, weldable couplers are the ideal solution. Made of low-carbon steel, they can be easily welded and allow connection to a threaded rebar.

Marco 81 é um projeto de torre alta localizada às margens do Rio Saigon, na Cidade de Ho Chi Minh. O projeto é de propriedade da empresa vietnamita Vingroup.

A construção da torre começou no final de 2014 e ela atinge uma altura de 470 metros até o tombamento, estabelecendo um novo recorde de altura no Vietnã. O Marco 81 é a 17ª torre mais alta do mundo.

Para este projeto, a Dextra está fornecendo seu renomado Bartec solução para o contratante Coteccons. A Bartec A solução foi aprovada pela ARUP, consultora representante do proprietário, e pela MACE International, consultora estrutural.

No total, 250.000 Bartec Os acopladores serão usados para conexões verticais de vergalhões na parede central e nas colunas, bem como para aplicações horizontais, como conexões entre a parede central e a viga e entre a parede central e a laje.

O uso de acopladores de vergalhões permite que a fôrma trepante avance sem obstáculos, além de permitir a conexão eficiente das barras iniciais da laje. Essas tecnologias, combinadas com o monitoramento de concreto de última geração, permitem ciclos de construção extremamente rápidos — de apenas 35 horas por andar.

Para aplicações compostas (colunas de aço para vigas), a Dextra também forneceu 20.000 acopladores soldáveis.

The new headquarters building of the National Bank of Kuwait is a 300m-tall tower with a total floor area of 127,000m². Its design, inspired by pearl shells, is located in the heart of Kuwait City’s financial district.

The main structure consists of composto concrete and steel, while the cladding on the fins and façades is predominantly glass-reinforced concrete.

Dextra contributed to reinforcing the building’s concrete structure by providing the following solutions:

• 100,000 Bartec acopladores were installed for column reforço, construction articulações in the raft, and slab/beam-to-core wall connections.
• 35,000 barras de cabeça acted as shear studs in the raft.
• 1,500 Unitec acopladores aparafusados were used to extend existing reinforcing bars that were either unthreaded or too short for lapping. This convenient solution allows for rebar connections using a simple pneumatic wrench on-site, eliminating the need for rebar preparation.

Big Box Retail is a new four-story retail center designed to have the smallest possible carbon footprint, featuring an innovative optimization of the air-conditioning load.

Located in Jebel Ali, Dubai, UAE, the center spans 81,000 square meters and offers a leasable area for over 100 retail and concept stores.

Dextra's Groutec couplers, integrated into the precast panels, made on-site assembly quick and efficient. More than 1,100 units of Groutec L. in 25mm and 32mm sizes were supplied.

Groutec is a high-performance precast connection solution that is easy to set up and fast to install on-site using grout injection. It supports the connection of precast concrete columns, panels, and beams.

The first phase of the retail center is set for completion in 2019, while the second phase will introduce a residential area, creating a new lifestyle hub in Dubai.

Ato Um | Torre do Ato Dois is a premium residential project in the Opera District of Downtown Dubai.

The development consists of two towers: Act One (52 stories) and Act Two (46 stories).

With their prime location, these residential towers offer stunning views of the Dubai Fountain and the Burj Khalifa. They are just a few minutes away from the Dubai Metro and major attractions such as the Dubai Mall and Souk Al Bahar.

For this exceptional residential project, Dextra was entrusted with reinforcing the buildings’ structures, including raft foundations, columns, slabs, and construction articulações.

A total of 150,000 Bartec rebar couplers, along with rebar preparation machines, were supplied to the construction site.

Bartec rebar couplers accelerate construction by providing a faster and more efficient way of connecting rebars compared to the traditional lapping method.

The thread on the rebar can be extended from a half-coupler to a full-coupler length, allowing the connection to be completed without rotating the bar.

The Floresta Gardens project involves the construction of towers within The Pearl Qatar.
