Belleville spring combined type three-dimensional vibration double-control steel support

Abstract

The invention discloses a belleville spring combined type three-dimensional vibration double-control steel support which comprises an upper cover plate, a limiting baffle, a guide column, a base, a belleville spring set, a sealing cover plate, an elastic unit, a box body, a first supporting plate and a second supporting plate. The first supporting plate and the second supporting plate are arranged between the base and the box body; the guide column is arranged on the base; the upper cover plate is arranged at the top of the guide column; the limiting baffle is arranged on the side face of the upper cover plate; the guide column is sleeved with the belleville spring set; the base and the box body are connected through the sealing cover plate; and an elastic element is arranged on the periphery of the base. The belleville spring combined type three-dimensional vibration double-control steel support can be used for reducing vertical vibration caused by a train environment and can also be used for reducing the earthquake effect, and the vibration-vibration double-control effect is achieved; and the second supporting plate is made of a steel plate, so that the durability problem of a common rubber support is solved.

Description

technical field [0001] The invention relates to the technical field of building supports, in particular to a disc spring combined three-dimensional vibration-vibration dual-control steel support. Background technique [0002] As an important means to alleviate urban pressure and realize urban renewal, the three-dimensional development of rail transit depot superstructure has been paid more and more attention. The complexity of the structural system composed of the rail transit vehicle depot structure and the superstructure complex is much higher than that of ordinary high-rise buildings. One is that there is a transition part of the structure that is prone to concentrated damage caused by a sudden change in stiffness, and it is necessary to use seismic isolation technology to solve the seismic problem; One of the bottlenecks of development. [0003] Therefore, in the design of the superstructure of the rail transit depot, it is necessary to adopt the vibration-vibration du...

AI Technical Summary

Problems solved by technology

[0006] When thick rubber pads are used, it is easy to cause the swaying problem of the superstructure under earthquakes, and the vertical bearing capacity of thick rubber pads is limited, so they can only be used for single-story or low-rise buildings, and it is difficult to use them for multi-story buildings with large loads, and Rubber has aging problems

[0007] To sum up, at present, the defects of bearings at home and abroad are that the vertical stiffness is small, the bearing capacity is low, and it is easy to sway under the earthquake. Ineffective, cannot be used in multi-story buildings
