King Power Mahanakhon, Thailand
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.
ฐานราก
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 ผนังไดอะแฟรม (D-Walls) to prevent water infiltration.
For the D-Walls of Mahanakhon, Dextra supplied บาร์เทค 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 การเสริมแรง.
Additionally, headed bars were installed in the thick foundation mat. บาร์หัว are a superior alternative to เหล็กเสริมปลายงอ in congested areas, offering high-performance anchorage while being easier to install.
โครงสร้างส่วนบน
The tower is built around a ผนังรับแรงเฉือน (จากแรงลมในอาคารสูง), constructed using slip-formwork, and is surrounded by 12 mega columns. To connect the columns to the ผนังรับแรงเฉือน (จากแรงลมในอาคารสูง), Dextra supplied Bouygues-Thai with its renowned บาร์เทค สารละลาย. บาร์เทค couplers, installed flush with the formwork and cast in concrete, allow for second-phase bar reconnection, bridging the columns and ผนังรับแรงเฉือน (จากแรงลมในอาคารสูง).
In the mega columns, rebar couplers were also used to perform bar-to-bar vertical connections.
สกายบาร์
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.
