AI Technical Summary

Problems solved by technology

Elastic tension-compression support is provided at the tension-compression fulcrum of the bridge structure. By controlling the elastic stiffness of this tension-compression elastic support, the problem of excessive local stress of the bridge structure in the flexible system bridge structure is solved, which makes the structure suffer. The force is more reasonable, and in some special working conditions (such as earthquake action), the structure can easily meet the force requirements

Embodiment Construction

[0016] The specific embodiments of the present invention will be described in detail below in conjunction with the technical solutions (and accompanying drawings).

[0017] The support top plate 1 of the tension-compression spring is fixedly connected with the bridge superstructure. If the bridge superstructure is a steel structure, it can be directly welded. If the bridge superstructure is a concrete structure, it can be connected with bolts. The support bottom plate 9 is fixedly connected with the bridge substructure by bolts.

[0018] The outer casing 2 is set outside the inner casing 3, and the disc spring group is placed in the inner casing 3, and the inner casing 3 is connected with the annular baffle 4 and the steel slide plate 7, which jointly protect the disc spring group and fix it. The role of the position, the size of the inner casing 3 is determined by the outer diameter of the selected disc spring, and then the size of the outer casing 2 is determined by the size...

Abstract

The invention provides a tension-compression elastic support which comprises a support top plate, an outer casing, an inner casing, an annular baffle, a steel core pillar, a spring partition plate, a steel sliding plate, a wear-resistant plate, a support bottom plate, an upper layer disk spring set and a lower layer disk spring set. The specification and the quantity of disk springs selected in the support are controlled, so that the elastic stiffness required by a structural design is provided, and the bearing capacity and deformation requirements of the support can be balanced; the tension-compression elastic support can be widely applied to the field of engineering design; the design problem that can be solved by large-scale design alteration before can be solved at very small cost; the structural design is more flexible; the stress is more reasonable; and the construction cost of engineering is lowered.

Description

technical field [0001] The invention belongs to the technical field of bridge structure design, and relates to a structure design of main components of a bridge, in particular to a vertical tension-compressible bridge elastic bearing. Background technique [0002] At present, the support of bridge tension and compression bearings to bridge structures is mostly rigid support. In the design of bridges with some special structures, if some tension and compression fulcrums adopt the traditional rigid tension and compression bearings in the past, the local stress of the structure will be too large. The force state does not meet the requirements of the code. In order to solve the above problems, the usual solution for bridge designers is to increase the structural size or improve the strength level of the component materials selected for design. However, the resulting increase in the structural volume , The cost rises, and the difficulty of construction increases. Contents of th...
