This technology is an architectural structure designed to reduce heavy-weight impact noise by installing L-shaped steel beams between opposing sidewalls beneath the floor slab, allowing the beams to exert an upward force against the underside of the slab.
Impacts from walking or running on a floor cause the slab to vibrate, transmitting noise to the floor below and often leading to disputes between neighbors. While current methods primarily involve installing cushioning materials on the floor surface, the intensity of floor impact noise is largely determined by the vibration characteristics of the slab structure itself, limiting the effectiveness of cushioning alone.
This technology uses steel beams longer than the distance between the sidewalls; when both ends are connected at the same height on the sidewalls, the center arches upward, pressing against the underside of the slab. The ends are connected via hinges, using 4–25mm thick rolled steel cambered beams with a 190–210mm height difference between the center and ends, spaced across the slab width with a natural frequency of 29–32Hz. Applicable to new residential buildings, ceiling reinforcement in existing apartments, and dormitory or office floor structures, it suppresses slab vibration from the ceiling space below without removing floor finishes, effectively reducing heavy-weight impact noise like footsteps.
