ICONSIAM, Thailand

ICONSIAM, Thailand

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 varilla corrugada Solución de empalme.

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 Anclajes finales are being used in the foundations and superstructure for the following applications:

L-shaped Clavija barras (uniones entre muro y losa)

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

Sustitución de Ganchos con Anclajes finales

Cuando la pared Refuerzo está especialmente congestionado, el uso de Anclajes finales (also called end anchors) allows for anchoring the Refuerzo in the wall without the need for hooks.

Conexión de doble extremo en muros de corte

Esta solución permite crear una continuidad en el interior de la columna o muro uniendo dos losas o vigas horizontales.

Acopladores soldados para Compuesto estructuras

Sometimes, it is necessary to start Refuerzo 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.

Landmark 81, Vietnam

Landmark 81, Vietnam

Landmark 81 is a high-rise tower project located on the banks of the Saigon River in Ho Chi Minh City. The project is owned by the Vietnamese company Vingroup.

Construction of the tower began at the end of 2014, and it reaches a height of 470 meters to tip, setting a new height record in Vietnam. Landmark 81 is the 17th tallest tower in the world.

Para este proyecto, Dextra suministra su reconocido bartec solution to the contractor Coteccons. The bartec solution has been approved by ARUP, the owner’s representative consultant, and MACE International, the structural consultant.

In total, 250,000 bartec couplers will be used for vertical rebar connections in the core wall and columns, as well as for horizontal applications such as core wall-to-beam and core wall-to-slab connections.

The use of rebar couplers allows the climbing formwork to progress unencumbered, while also enabling efficient connection of slab starter bars. These technologies, combined with state-of-the-art concrete monitoring, facilitate extremely fast construction cycles—as short as 35 hours per floor.

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


Example of weldable Bartec coupler on beam

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

National Bank of Kuwait – New Headquarter, Kuwait

National Bank of Kuwait – New Headquarter, Kuwait

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 Compuesto 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 Refuerzo, construction juntas in the raft, and slab/beam-to-core wall connections.
  • 35,000 barras con cabeza acted as shear studs in the raft.
  • 1,500 Unitec acopladores atornillados 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.

Plum Condo Estación de Bangyai, Tailandia

Plum Condo Estación de Bangyai, Tailandia

Estación de Bangyai del condominio Plum Es un proyecto de condominios de 38 pisos compuesto por dos torres, ubicado cerca de la estación de metro elevada Bangyai, en el noroeste de Bangkok. El edificio residencial albergará 1013 apartamentos.

La fase 1 del proyecto (la primera torre) comenzó en septiembre de 2015 y se espera que se complete alrededor de marzo de 2018. La rápida construcción es posible gracias al uso de totalmente prefabricado técnicas concretas.

El propietario del proyecto, Pruksa, está operando su propia planta de prefabricados específicamente para este desarrollo.

Para este proyecto, Pruksa se propuso erigir rápidamente paneles prefabricados (que sirvieran como muros de corte) para todos los niveles sobre el suelo. Para cumplir con este requisito, Dextra recomendó el uso de Groutec acopladores.

Los acopladores Groutec se montaron en Varillas de refuerzo de Ø25 mm, que había sido previamente enhebrado utilizando el bartec Sistema. Los acopladores, instalados en la parte inferior de cada elemento prefabricado, se fundieron luego como parte del panel de pared prefabricado.

Después de levantar el elemento hasta el piso superior en el sitio, se logró la reconexión con el refuerzo saliente mediante inyección mortero sin contracciónEs importante tener en cuenta que Dextra no suministra el mortero; en cambio, este puede obtenerse localmente, lo que genera un ahorro significativo en costos. Una vez inyectada la lechada, los soportes alrededor de cada panel pueden retirarse después de tres días.
