Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building seismic isolation, and more specifically, to a novel rubber seismic isolation support. Background Art
[0002] In order to meet the seismic requirements of buildings, it is necessary to set up seismic isolation bearings in the buildings. When the rubber seismic isolation bearings are connected to the seismic isolation piers, the middle is connected by a steel plate pre-buried on the pier in advance. The traditional construction method uses a solid steel plate pre-buried on the pier. During the construction process, the concrete in the pier part under the center of the steel plate is not easy to be poured densely, which affects the engineering quality of the pier.
[0003] After searching, a Chinese patent with announcement number CN210263409U discloses a new type of rubber seismic isolation bearing for construction. The shock-absorbing components of existing seismic isolation bearings mostly adopt a simple rubber and lead core structure, which is easy to undergo irreversible deformation due to long-term use, resulting in increasingly poor effects over time. At the same time, traditional bearings are not convenient to be tightly connected with other supporting structures during use, and have poor practicality. The stability of the rubber seismic isolation bearing can be increased by arranging rigid pads at equal intervals between the rubber pads, thereby avoiding irreversible deformation of the shock-absorbing pads during long-term use, thereby increasing the service life of the bearing. At the same time, the outer protective rubber sleeve with a seamless structure arranged on the outer surface of the shock-absorbing pad can increase the safety of the bearing and avoid rubber cracking due to excessive pressure. The lower mounting column and the upper mounting column can facilitate the fixed installation of the bearing and the mounting structure, thereby improving the practicality of the bearing and facilitating promotion and use.
[0004] During the use of the seismic isolation bearing, the seismic isolation pier has a large interface and is provided with a pre-buried solid steel plate, so the poured concrete is not easy to flow to the middle part. At the same time, since the center of the steel plate is not conducive to the discharge of air, gaps are easily generated under the pre-buried solid steel plate. In addition, because there is a pre-buried solid steel plate on the interface of the seismic isolation pier, the concrete in the pier part below the center of the steel plate cannot be vibrated, making it difficult to ensure the density of the concrete in the pier part below the center of the steel plate.

[0016] 1.
