Multi-directional shock absorption protection system for high-rise and flexible structure and shock absorption method

Abstract

The invention discloses a multi-directional shock absorption protection system for a high-rise and flexible structure, and further discloses a shock absorption method using the multi-directional shockabsorption protection system. The multi-directional shock absorption protection system includes a ring-shaped steel fastener unit, a ring-shaped fixing unit and a plurality of energy dissipation shock-absorbing units; the ring-shaped steel fastener unit sleeves the upper part of the high-rise and flexible structure, the ring-shaped fixing unit sleeves the bottom of the high-rise and flexible structure and is fixed to the ground, and the multiple energy dissipation shock-absorbing units are connected with the ring-shaped steel fastener unit and the ring-shaped fixing unit; and the energy dissipation shock-absorbing units is each composed of an upper side force transmission unit, a cylindrical damper and a lower side force transmission unit, and each of the cylindrical dampers includes an upper threaded-joint steel sleeve, a lower threaded-joint steel sleeve, a peripheral steel cylinder, an upper sealing steel plate, a lower sealing steel plate, an upper force transmission steel plate,a lower force transmission steel plate, an upper pre-compression spring, a lower pre-compression spring, an upper piston steel plate, a lower piston steel plate, an upper force transmission rod, a lower force transmission rod, an upper first inner steel cylinder, a lower first inner steel cylinder and a second inner steel cylinder. The multi-directional shock absorption protection system can achieve multi-directional shock absorption, and is efficient and flexible.

Description

technical field [0001] The invention belongs to the technical field of shock absorption and protection, and in particular relates to a multi-directional shock absorption and protection system with a high-flexibility structure and a shock absorption method thereof. Background technique [0002] Earthquakes and strong winds (typhoons) have long posed a huge threat to the safety of high-flexible structures. Earthquakes and strong winds (typhoons) that have occurred in the past have affected towering trees (especially relatively fragile trees with historical and cultural value and research value), high and soft historical and cultural ancient buildings (such as pagodas, etc.), chimneys, water towers and other high and flexible structures. All of them suffered serious damage and damage, and even overturned or collapsed, causing huge losses. As a superior vibration control technology, vibration reduction technology is effectively applied to the control of earthquake and strong wi...

AI Technical Summary

Problems solved by technology

[0003] At present, the use of shock-absorbing devices is generally directly added to the building structure itself for energy dissipation and shock absorption of the structure, while high-flexible structures are often difficult to install due to the characteristics of their own structural form, and the installation efficiency and adjustment flexibility are low. The process often causes damage to the original structure
