Nested water tank capable of reducing vibration and dissipating energy

Abstract

The invention relates to a nested water tank capable of reducing vibration and dissipating energy. The nested water tank comprises a spring shock-absorbing seat. A water tank body is arranged on the spring shock-absorbing seat and comprises an outer-layer water tank. A middle-layer nested water tank is arranged in the outer-layer water tank, an inner-layer nested water tank is arranged in the middle-layer nested water tank, and a pressure relief opening is formed at the top end of the outer-layer water tank. The nested water tank capable of reducing vibration and dissipating energy has the advantages that fire demand water or domestic water can be stored on a roof or a mechanical floor of a general high-rise building or a super high-rise building by utilization of the nested water tank, structural vibration energy can be dissipated through dampening effect when an earthquake or strong breeze disaster occur, vibration amplitude of the water tank body and the building is reduced, and damage of the earthquake to the main body structure of the building and the water tank body is reduced. In addition, effect of vibration reduction and energy dissipation is good, efficacy loss cannot occur easily, application range is wide, applicability is strong, the structure is simple, manufacture and installation are convenient, an existing water tank can be transformed to be the nested water tank, cost is low, dual functions of the water tank are achieved, and practical applicability is strong.

Description

technical field [0001] The invention relates to a nested water tank for vibration reduction and energy dissipation. Background technique [0002] With the deepening of my country's urbanization process, the construction land in the core areas of first-tier and even second-tier cities is becoming increasingly scarce, and the number of high-rise and super high-rise buildings is increasing rapidly. This type of building is more susceptible to strong external excitations such as wind and earthquakes, which can cause discomfort to users in the slightest and cause structural damage to the building in severe cases. In order to reduce the impact of wind and earthquake on the building structure, it is often necessary to design dampers in high-rise buildings to reduce the vibration response of the structure. Combined with high-level water tanks in high-rise buildings, it is more reasonable to set up liquid dampers to reduce vibration. In addition, in the equipment installation engin...

Problems solved by technology

However, this patent does not set a spring shock absorber as the water tank base, and the rigid connection of the water tank base is easily damaged when an earthquake or strong wind occurs, causing the damper to fail

There is no nested structure with spring connection inside the water tank, and the ability to consume shock energy is limited, and the use of turnbuckles to rigidly connect the partitions is also likely to cause structural damage to the relatively thin side walls of the water tank during strong earthquakes; in addition, the existing The design and research of the water tank used as a liquid damper does not involve the foundation of the water tank, and the connection between the water tank and the building generally adopts a rigid connection similar to an ordinary water tank

In the event of an earthquake or strong wind disaster, the mass of the water tank filled with water is relatively large. If a rigid connection is used between the water tank and the foundation, the rigid connection is likely to be damaged during vibration, resulting in the failure of the damper, and the large-scale displacement of the water tank endangers the structural safety.
