Ultra-thin anti-seismic bearing

Abstract

The invention discloses an ultra-thin aseismic pedestal. The ultra-thin aseismic pedestal is not larger than 15 cm in the height direction and comprises an upper part, a middle part and a lower part, wherein the upper part is used for being connected with a supported object and is elastomer; the middle part has the two-dimensional movement capacity on the horizontal plane and consumes horizontal vibration and impact force in the movement process; the middle part comprises a first sliding board, a second sliding board and a fixed board; the first sliding board and the second sliding board are in sliding fit; the second sliding board and the fixed board are in sliding fit; and the lower part (3) is used for being connected with a supporting beam or column and is elastomer. The product is flattened, by the adoption of the structure of the pedestal, under the condition that the bearing force and aseismic performance are not changed, the height is reduced by about 60%, flattening of the product is achieved, and more advantages are achieved in the bridge and building installation process. The height of the pedestal is reduced, so that stabilization of bridges and buildings is more facilitated.

Description

technical field [0001] The invention relates to a support widely used in the field of engineering technology, in particular to an ultra-thin support with a three-dimensional buffer function. Background technique [0002] In bridge engineering, prefabricated buildings, and steel structure buildings, bearings are widely used. The main function of bearings is to resist earthquakes and reduce impact. [0003] When the magnitude of the earthquake is large or the "hard resistance" of the structure is difficult to meet the expected seismic requirements due to some reasons, the use of seismic isolation technology to reduce the input seismic energy of the structure can achieve good results. The essential function of seismic isolation is to separate the structure or components from the seismic ground motion or support motion that may cause damage, cut off the transmission path of seismic energy, reduce the seismic force and energy input to the building structure, thereby reducing the ...
