AI Technical Summary

Technical Problem

In high-rise residential buildings, noise pollution caused by high-speed elevators affects residents' lives. Traditional noise reduction methods have environmental problems, safety hazards, and high costs, and also occupy indoor space.

Method used

Precast elevator shaft interior wall anti-fall noise reduction panels are used, including noise reduction panels, cast-in-place concrete and anti-fall connectors. The anti-fall connectors are cast in one piece, combined with the design of protruding and grooved panels, and are made of fabric glass wool and polyester fiber materials, with iron brackets and expansion bolts for fixation.

Benefits of technology

It achieves efficient noise reduction, prevents falling off, reduces safety hazards, saves costs, expands indoor space, and is integrated with the building structure, reducing maintenance costs.
