Hyundai E&C has received certification for technology related to an apartment structure that allows for flexible floor plans and is resistant to inter-floor noise.
Hyundai E&C noted on the 23rd that it held a ceremony commemorating the certification of the 'Residential PC (Precast) Ramen Beam-Column Connection Technology' at the 'H Silent Lab' inter-floor noise research facility in Yongin, Gyeonggi Province, on the 21st.
The beam-column ramen structure, which is column-based, has the advantage of being able to freely arrange the floor plan without walls separating the spaces. The vibrations transmitted from the floor are dispersed through the beams and columns, enhancing the inter-floor noise reduction effect. However, it is more expensive compared to wall-type structures that support the building load with walls. Currently, most apartments in South Korea employ wall-type structures.
The technology that Hyundai E&C has received certification for this time is a connection technology used to construct ramen structures using an off-site construction (OSC) method. Each member is produced at the factory and then transported to the construction site for assembly. Hyundai E&C has developed technology to enhance the structural safety of beam-column connections in collaboration with CAMUS E&C.
Hyundai E&C is the first to receive a technology certification for residential PC ramen structure connection technology. Hyundai E&C has been conducting research to commercialize a first-grade floor structure for inter-floor noise by applying a combination of wall-type structures and PC (Precast) ramen structures at the 'H Silent Lab' opened in 2023.
A representative from Hyundai E&C said, 'We expect this will be an opportunity for the expansion of PC ramen structure application on apartment sites in the future,' and noted, 'We will focus on developing related technologies.'
