King Power Mahanakhon is a 77-storey skyscraper in Bangkok. Standing at 314 meters, it became Thailand’s tallest building upon its completion in 2016. Mahanakhon is located in Silom, Bangkok’s busiest business district, directly above the Chong Nonsi BTS Skytrain station. The project was developed by PACE and built by Bouygues-Thai.

नींव

Building foundations in Bangkok is always a challenge. With the city situated on sandy and humid soils, foundations must be deep, and most projects feature thick डायाफ्राम की दीवारें (D-Walls) to prevent water infiltration.

For the D-Walls of Mahanakhon, Dextra supplied बार्टेक rebar couplers that were mounted on hook bars, installed horizontally, and cast in concrete. This application allows for the reconnection of bars to the D-Wall at a later stage when starting slab मजबूतीकरण.

Additionally, headed bars were installed in the thick foundation mat. सिर वाली सलाखें are a superior alternative to हुक वाले बार्स in congested areas, offering high-performance anchorage while being easier to install.

सुपरस्ट्रक्चर

The tower is built around a कोर दीवार, constructed using slip-formwork, and is surrounded by 12 mega columns. To connect the columns to the कोर दीवार, Dextra supplied Bouygues-Thai with its renowned बार्टेक समाधान। बार्टेक couplers, installed flush with the formwork and cast in concrete, allow for second-phase bar reconnection, bridging the columns and कोर दीवार.

In the mega columns, rebar couplers were also used to perform bar-to-bar vertical connections.

For the rooftop skybar, Dextra supplied Tension Rod Systems. These systems, equipped with fork ends, provide aesthetic and efficient anchorage, making installation simple and effective.
