Water damping shock absorption device used for building

Abstract

The invention relates to the technical field of earthquake proofing, and discloses a water damping shock absorption device used for a building. The water damping shock absorption device comprises two water boxes, two weight baskets and two cables, wherein the two water boxes are arranged on two sides of the lower side of an external wall of the building; one end of each cable is fixed on one side of the top of the external wall of the building, the other ends of the cables are used for fixedly hanging the weight baskets, and the two cables are arranged in a crossed mode; the two weight baskets are movably arranged in the water boxes respectively; balancing weights are arranged in the weight baskets. According to the water damping shock absorption device, water is adopted as damping substances and is low in price and easy to obtain, and cost is reduced; the water is placed at the bottom of the building, the structure is simple, installation convenience is achieved, and the water damping shock absorption device can be used for a long time without frequent maintaining; after an earthquake, a shock absorber is not prone to damage and can be repeatedly used; the water damping shock absorption device not only is suitable for new buildings, but also can be added to old buildings.

Description

technical field [0001] The invention relates to the field of anti-seismic technology, in particular to a water damping and shock absorbing device for buildings. Background technique [0002] Earthquake disasters often have a fatal impact on building structures, and various anti-seismic devices play a role in protecting structures. At present, the shock absorption principle of the existing water damping and shock absorbing devices is to use a water tank to place the water medium on the upper part or top of the building, and to balance the forward movement of the structure through the reverse movement of the water mass under the action of the earthquake, so as to reduce Vibration of small structures. Existing water damping devices can be divided into two types: support type and suspension type. The support type water tank damping system is to install a type of vibration isolation support such as a lead rubber support at the bottom of the water tank. For example, CN101709595...

Problems solved by technology

[0003] The above two types of water tank dampers need to place a huge water mass on the upper part or top of the building, so the structure is complicated, the installation is inconvenient, and frequent maintenance is required, and once it fails, it will cause a huge safety hazard
