Abstract

The invention relates to a wind-resistance spherical supporting base of a novel structure. The supporting base is provided with a base plate IV (7). One side of an arc spherical face of a base plate III (6) in a groove in the middle of the base plate IV (7) is in matched fit with the arc bottom face of a groove in the middle of the base plate IV (7). One side of a segment face of a base plate V (15) on one side of the base plate IV (7) is in matched fit with the arc spherical face of the base plate IV (7). The base plate IV (7), the base plate III (6) and the base plate V (15) form a rotating mechanism of the supporting base, and the bearing and rotating function of the supporting base in the transverse direction of bridge is achieved. The other side of the base plate IV (7) is provided with a base plate II (4), and a spring (5) is arranged between the base plate II (4) and the base plate III (6), so that an elastic bearing structure of the supporting base is formed. According to the supporting base, the functions of load transfer in the transverse direction of bridge, displacement in the longitudinal direction of bridge and displacement in the vertical direction of bridge are achieved.

Description

technical field [0001] The invention belongs to the technical field of bridge structures, and is a bearing product that can be used for bridges, in particular to a wind-resistant spherical bearing with a new structure. Background technique [0002] In recent years, a large number of cable-stayed bridges and suspension bridges with large spans and large bearing capacity have been designed and built in succession in response to the needs of my country's national economic development. Between the inner side of the tower body and the outer side of the beam body of these cable-stayed bridges and suspension bridges, wind-resistant bearings are installed vertically, and the bearings are respectively anchored and connected to the tower body and the beam body. The wind-resistant bearing can limit the large-distance swing of the horizontal bridge of the beam body caused by wind or earthquake force, bear the horizontal horizontal force transmitted by the beam body, and at the same time...
