Garden Composite Structure with Anti-seismic Function

Abstract

The invention discloses a garden composite structure with anti-seismic function, which comprises a garden structure column, a garden structure column foundation and an anti-seismic structure arranged between them; the anti-seismic structure includes an outer frame, a movable inner frame, and a piston type viscous damper , roller balls and transition boards. The garden composite structure has remarkable anti-seismic effect; the structure design is reasonable, the installation and maintenance are convenient, the cost is low, and it can be used repeatedly in multiple earthquakes.

Description

technical field [0001] The invention belongs to the technical field of garden architecture, and relates to a garden composite structure with anti-seismic function. Background technique [0002] Earthquake is a very destructive sudden natural disaster, which will cause heavy casualties and property losses. my country is an earthquake-prone country. According to relevant reports from the China Earthquake Administration, since 1950, there have been an average of 24 earthquakes of magnitude 5 or above in mainland China every year. Even in 2018, when the overall disaster situation was significantly lighter than the average of the past five years, the direct economic loss caused by the earthquake was as high as 3 billion yuan. Therefore, using existing facilities to mitigate earthquake disasters is also a long-term demand in disaster prevention and mitigation projects. For example, in recent years, large-scale green spaces have been used as emergency shelters for citizens to rel...

Problems solved by technology

[0004] The above-mentioned gear-type shape memory alloy damper with response amplification effect has the following problems if it is applied to the anti-seismic of garden composite structures: the cost of the damper is relatively high, and it is suitable for use in large-scale structures or important projects. It is not economical and practical enough; and the damper can only isolate and absorb shocks in a single direction. When an earthquake occurs, even if only the horizontal earthquake action is considered, its directionality is still difficult to predict, so the shock absorption effect is poor; in addition, when an earthquake occurs, in Under the action of an earthquake, once the half gear or the whole gear is misaligned under the force, it is very easy to cause the meshing rack to lock with it, resulting in the failure of the damper and the failure to work normally.
