Abstract

The invention discloses a self-adaptive bridge support which comprises an upper supporting piece used for supporting a bridge and a supporting base used for installing the upper supporting piece. Theupper surface of the supporting base is connected with a supporting bulb in spherical surface cooperation with the bottom face of the upper supporting piece. Multiple reset assemblies connected with the upper supporting piece and the supporting base and used for resetting the upper supporting piece and a limiting assembly used for limiting the rotation angle of the upper supporting piece are arranged around the supporting bulb on the upper surface of the supporting base. Through spherical surface cooperation, adjustment in any direction can be achieved through external force self-adaptive distribution, the rotation angle of the upper supporting piece rotating around the supporting bulb is limited through the limiting assembly, and an overturning phenomenon can be effectively prevented. Inthe structure, the supporting bulb is used for bearing a load, the stress of the reset assemblies and the limiting assembly in the normal state is greatly reduced, fatigue damage of parts and deformation and failure of the parts due to too large stress are effectively avoided, the service life of the reset assemblies and the limiting assembly is prolonged, and system stability and reliability areimproved.

Description

technical field [0001] The invention belongs to the technical field of roads and bridges, and relates to a bridge support structure, in particular to an adaptive bridge support. Background technique [0002] With the development of the national economy, the role of transportation infrastructure construction in promoting the development of the national economy is also becoming more and more significant, among which bridge construction occupies a considerable proportion in the construction of transportation infrastructure. In bridge engineering, railway and highway bridges can reliably transmit the reaction force and deformation of the upper structure of the bridge to the lower structure of the bridge through the support, thereby improving the stability of the bridge; [0003] In addition to the horizontal thrust and vertical pressure, the external force on the support also has the influence of the bias pressure caused by the rotation of the beam body on the support; the Chine...
