Expansion Joint is a device installed to absorb the movement gap between superstructure and substructure caused by movement and circulation of superstructure by elasticity of temperature change, dry contraction of concrete, cliff and live load and to minimize shock when vehicles pass.
It has been widely used thanks to an increase of eco-friendly and landscape focused design. UNISION eTECH produces color soundproof plate(absorption/reflection), transparent soundproof plate, light soundproof plate, high reduction soundproof plate, fireproof soundproof plate, noise interference device and soundproof tunnel.
It minimizes internal structure change or thick increase to have high Sound Absorption of over 85% NRC in KS (KSF 4770), and is to have grade 1 performance of NRC
High Absorbing Color Soundproof Plate
It is the lightest product in Korea with 15kg/m2 developed for bridge, existing structure and soundproof tunnel.
Wooden and transparent types are becoming used widely according to eco-friendly soundproof wall installation for lighting and visibility.
Noise interference device is installed on top of soundproof wall to reduce noise using interference and diffraction principles of sound.
It is a sound reduction technology using the difference of diffraction. When sound penetrates an interference device, its sound directly enter on top of soundproof wall.
Soundproof tunnels are considered a representative way to perfectly prevent noise by minimizing the effect of diffracted sound taking place in the general areas of upper and lower parts in existing vertical soundproof walls.
Mold is a frame to produce segment and PC products (file, pole, culvert and block). We carry out design, manufacture and delivery according to segment and P.C. product shape.
A monorail is a railway in which the track consists of a single rail. The term is also used to describe the beam of the system, or the vehicles traveling on such a beam or track.
