Fan blade type steel damper and vibration reduction and isolation support seat

Abstract

The invention discloses a fan blade type steel damper and a vibration reduction and isolation support seat, wherein the fan blade type steel damper used as a core component comprises a flat plate part, an enclosure, fan blades and a pin hole, wherein the downwards extending enclosure is arranged at the lower side of the flat plate part; the upper side of the flat plate part is provided with a circular ring-shaped lug boss; the plurality of fan blades made of soft steel materials are uniformly arranged in the inside space of the lug boss; a round sleeve is arranged at the inner ends of the plurality of fan blades; the pin hole is formed in the round sleeve, and is in concentric arrangement with the lug boss; a downwards extending positioning post is arranged in the pin hole and an upper part carrying mechanism and is used for insertion and connection matching. The vibration reduction and isolation support seat has the advantages that the carrying capacity is high; the vibration reduction effect is good; the work performance is stable; the durability is high; the plane dimension is small, and the like. The fan blade type steel damper and vibration reduction and isolation support seat is applicable to most bridges or other building structures with anti-vibration requirements.

Description

technical field [0001] The invention relates to a support, in particular to a shock-absorbing and isolating support. Background technique [0002] Earthquake is one of the natural disasters that pose a great threat to human beings. Once bridges and other building structures are damaged during an earthquake, it will pose a serious threat to the safety of human life and property, and will also lead to secondary disasters. As a reasonable and effective anti-seismic means, anti-seismic technology has been more and more used in bridges and other building structures. Among them, the anti-seismic bearing is one of the most widely used anti-seismic devices. At present, the more common anti-vibration bearings include lead core rubber bearings, high damping rubber bearings, friction pendulum bearings and steel damping bearings. [0003] Lead core rubber bearings have insufficient bearing capacity and poor durability, causing pollution to the environment, and are facing the situation ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the deficiencies of the prior art, the present invention provides a fan blade steel damper and a shock-absorbing and isolating support, which are used to solve the problem of poor seismic performance and at the same time solve the problem of large volume of the existing shock-absorbing and isolating supports
