Damping and shock insulating spherical fixing support

Abstract

The invention discloses a damping and shock insulating spherical fixing support which comprises a lower support plate, an upper support plate, anchor bolts, sleeves as well as guide plates and shearing bolts, wherein a damping rubber plate, a spherical concave liner plate, a spherical surface sliding plate, a spherical crown liner plate and a damping sliding plate are further sequentially arranged from bottom to top between the lower support plate and the upper support plate; the damping sliding plate and the spherical surface sliding plate are respectively adhered to the upper and lower sides of the spherical crown liner plate; four sets of guide plates and shearing bolts are provided; the guide plates are fixed at the front, rear, left and right ends of the upper support plate through the shearing bolts. Due to adoption of the damping rubber plate on the lower support plate, the vertical kinetic energy of a bridge is converted into potential energy and heat energy of the bridge itself in earthquake, and then the impact of components of the support is alleviated; as the guide plates are fixed on the upper support plate through the shearing bolts, if the shearing bolts are cut off, the support can be recovered to a normal use state by only replacing the shearing bolts and resetting the guide plates.

Description

technical field [0001] The invention relates to the technical fields of bridges and construction engineering, in particular to a shock-absorbing and shock-isolating ball fixed bearing with good shock-absorbing effect. Background technique [0002] Earthquakes are vibrations on the earth's surface caused by the sudden release of slowly accumulated energy inside the earth; strong ground vibrations will directly and indirectly cause the collapse and destruction of bridges and buildings, becoming disasters. [0003] Since the 20th century, a large number of scholars have devoted themselves to the scientific research of earthquakes. Until the 1950s, the "Earthquake Engineering Theory System" was basically established to understand the causes and mechanisms of earthquakes in a correct sense. After the 1970s, the theory of anti-seismic development developed rapidly, especially the technology of shock absorption and isolation was proposed, which played a revolutionary role in the an...

Problems solved by technology

[0009] In view of the above-mentioned prior art, the object of the present invention is how to provide a shock-absorbing and shock-isolating ball fixed support, which aims to solve the problem that the existing shock-absorbing and shock-isolating supports can only weaken the kinetic energy in the horizontal direction, but cannot absorb or weaken the vertical kinetic energy. Kinetic energy in the vertical direction and technical problems that are not self-recoverable and cannot be repaired
