Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of suspended ceiling installation, in particular to a shock-absorbing suspended ceiling structure suitable for low-rise high buildings and a method for installing the same. BACKGROUND

[0002] A suspended ceiling system is an important part of a building. The suspended ceiling system has the following problems: the non-structural component is generally suspended at a high position in the building. When the building is subjected to an earthquake, external force does not directly act on the non-structural component, but is transmitted to the non-structural component after being amplified by the reaction of the main structure. Compared with the main structure, the mass and stiffness of the non-structural component are much smaller, which easily causes the natural frequency of the non-structural component to be close to the frequency of the main structure, resulting in resonance and causing the dynamic response of the non-structural component to be particularly strong. The coupling system composed of the main structure and the non-structural component is a non-classical damping system, and the damping ratio of the non-structural component is much smaller than that of the main structure, which cannot weaken the resonance effect. The non-structural component can be single-point supported or multi-point supported, and when it is multi-point supported, the mechanisms of the supporting points are out of sync, which can cause torsional effects.

[0003] Some current assembly-type suspended ceiling systems do not have a related shock-absorbing structure or shock-absorbing device, and the anti-seismic effect is not ideal. When the suspended ceiling system is subjected to an earthquake, the suspended ceiling system is prone to dysfunction or even loss of function, and the following situations occur: the joist is damaged and broken, the decorative panel is detached, and the like. The suspended ceiling system cannot operate or be repaired, and thus needs to be rebuilt. Some buildings have a low height, and thus have strict requirements for the installation space of the assembly-type suspended ceiling. However, some current suspended ceiling systems have a large occupied space, and thus are not suitable for installation in low-rise high buildings. SUMMARY
