Torsion support with vertical displacement function

Abstract

The invention discloses a torsion support with a vertical displacement function. The torsion support comprises a support top board, a support bottom board and position control springs. A bulb base isarranged in the center position of the bottom face of the support top board, and a supporting bulb is installed on the bulb base. A supporting base is arranged in the center position of the support bottom board, the supporting bulb is arranged in the supporting base, and the supporting bulb and the supporting base are spherically hinged. The four position control springs are arranged and evenly arranged between the support bottom board and the support top board in the circumferential direction with the supporting base as the center so as to pull and connect the support top board with the support bottom board. The torsion support can provide X-axis, Y-axis and Z-axis displacement, X-axis, Y-axis and Z-axis coupled rotating angle displacement and vertical translational motion displacement, the effects that the torsional amplitude of a bridge floor is controlled, and the torsion vibration characteristic of a bridge is changed are achieved, brittle failure of the connecting position of a pier and the bridge floor is effectively avoided, and the safety of the bridge is enhanced. The torsion support has the beneficial effects that applicability is wide, installation is convenient, the support can be automatically reset, and parts can be replaced.

Description

technical field [0001] The invention relates to a bearing suitable for bridges, in particular to a torsional bearing with vertical displacement. Background technique [0002] The bridge deck of the bridge is usually supported on the bridge piers. During the use of the bridge, the bridge is subjected to transverse wind, earthquake, dynamic load on the bridge deck, etc., and the relative torsional movement of the bridge deck and the bridge piers is easy to occur. It will affect the normal use of the bridge, and even cause fatigue damage to the bridge structure. In severe cases, it will also lead to the overall damage of the bridge structure, which will have a great impact on the safety of the bridge structure, the operation safety of vehicles on the bridge and the comfort of passengers. . Therefore, torsion bearing is of great significance for solving such problems. Contents of the invention [0003] The object of the present invention is to provide a torsional support wit...
