Description

Technical Field

[0001] This utility model relates to the field of indoor ceiling technology, specifically to an indoor shock-absorbing and noise-reducing ceiling structure. Background Technology

[0002] A suspended ceiling refers to the decoration and structure at the top of an interior space. It not only beautifies the interior environment but also has practical functions such as concealing pipes, lighting equipment, and air conditioning systems.

[0003] Ceiling noise is a common indoor environmental problem, which can be caused by a variety of factors, including airborne noise, vibration transmission from the upper floor, and resonance of the ceiling material. Current technologies have made various attempts to reduce noise caused by vibration transmission, such as changing the installation method from hanging to side fixing, so that the ceiling panel does not directly contact the ceiling. However, this fixing method lacks effective support, resulting in stability issues. Alternatively, shock absorbers can be installed on multiple hooks to reduce resonance between the upper floor slab and the ceiling material, but this not only increases the workload but also raises the cost of the ceiling. Therefore, an economical noise reduction and vibration damping structure that does not affect overall stability is needed. Utility Model Content

[0004] This invention aims to solve the aforementioned technical problem of noise caused by vibration transmission in ceiling structures, and provides an indoor vibration-damping and noise-reducing ceiling structure.

[0008] The sound-absorbing structure includes a sound-absorbing layer on a calcium silicate board, and a sound-absorbing layer on the sound-absorbing layer, wherein a plurality of sound-absorbing holes are evenly distributed on the sound-absorbing layer.

[0009] Furthermore, the lower end of the boom is provided with threads on its outer side, the upper end of the connector is provided with a through hole that can accommodate the boom, and the boom is provided with locking nuts on both the outer side and at the upper and lower ends of the through hole;

[0010] Both sides of the connector are provided with corresponding through holes II. A screw rod is inserted through the through holes II. The screw rod is higher than the main keel. Both ends of the screw rod extend out of the through holes II and both ends are provided with nuts.

[0014] Furthermore, hollow cylinders are provided inside the shock-absorbing pad and corresponding to the three mounting holes.

[0015] The advantages of this utility model compared with the prior art are as follows:
