Embodiment 1

[0049] see figure 1 , this embodiment proposes an elastic body, the elastic body 2 is a multi-layer structure, the multi-layer structure is a layer of rigid parts 21 and a layer of elastic parts 22 alternately arranged, the outermost layer of the elastic body 2 is The rigid part 21, the elastic part 22 is connected with the rigid parts 21 on both sides thereof.

[0050] Regarding the material, the elastic member 22 is rubber, the rigid member 21 is a steel plate, and the rubber is vulcanized and bonded to the steel plates on both sides.

[0051]The elastic body 2 is composed of one layer of steel plate and one layer of rubber. Its structure is completely different from that of springs, ordinary laminated rubber and rubber bodies. The elastic body 2 can realize vertical displacement and can be adjusted according to the displacement. The structural size of the elastic body 2 can not only be used in the bearing of bridge construction, but also can be used independently in any pl...

Embodiment 2

[0054] see figure 2 , The difference between this embodiment and Embodiment 1 is that: the rigid member 21 and the elastic member 22 are plate-shaped, and the cross-section of the formed elastic body 2 is rectangular.

Embodiment 3

[0056] see image 3 , this embodiment proposes a vertical elastic structure, including an upper part 1 and a lower part 3, the elastic body 2 described in embodiment 1 or embodiment 2 is arranged between the upper part 1 and the lower part 3, and the upper part 1 There are several first protruding teeth 11, which are in rigid contact with the upper surface of the rigid part 21 of the elastic body 2, and the lower part 3 is provided with several second protruding teeth 31, which are in contact with the rigid part 21 of the elastic body 2. The lower surface of the first protruding teeth 11 and the second protruding teeth 31 are arranged in a staggered manner.

[0057] In this embodiment, the widths of the first protruding teeth 11 and the second protruding teeth 31 are equal to the thickness of the rigid member 21; the upper part 1 and the lower part 3 are rigid bodies.

[0058] The lower part 3 has a groove, the second protruding tooth 31 and the elastic body 2 are located in ...

Abstract

The invention relates to the technical field of bridge structures, provides an elastic body, a vertical elastic structure and a vertical elastic support, and aims to solve the problems that when a spring or a rubber body is adopted to achieve the compression elastic function of a support, the installation height is high, the bearing curve curvature is small, and the later operation state of a bridge is seriously affected. The elastic body is of a multi-layer structure, one layer of rigid pieces and one layer of elastic pieces are alternately arranged, and the elastic pieces are connected with the rigid pieces on the two sides of the elastic pieces. The vertical elastic structure comprises an upper portion and a lower portion, the elastic body is arranged between the upper portion and the lower portion, a plurality of first protruding teeth are arranged on the upper portion, a plurality of second protruding teeth are arranged on the lower portion, and the first protruding teeth and the second protruding teeth are arranged in a staggered mode. The vertical elastic support comprises the vertical elastic structure, and the upper portion and the lower portion of the vertical elastic support are support bodies. The elastic body, vertical elastic structure and vertical elastic support have the advantages of being large in vertical displacement, capable of meeting the rigidity requirement, low in installation height and wide in elastic body application range, not only can be applied to supports for bridge construction, but also can be independently applied to any places needing vertical displacement and rigidity requirements.

Description

technical field [0001] The invention relates to the technical field of bridge structures, in particular to an elastic body, a vertical elastic structure and a vertical elastic support. Background technique [0002] With the rapid development of bridge construction in our country, more and more long-span bridges have been built. In the construction of approach bridges, the influence of the vertical displacement of the approach bridge on the entire bridge and traffic is often considered. To release this vertical displacement, the usual method is to install compressive elastic bearings or other devices on the upper part of the bridge pier. [0003] In order to realize the compressive elastic function, springs or rubber bodies are often used. In the case of large vertical displacement and strict rigidity requirements, the installation height of such supports or devices is very high and the curvature of the wind curve is small, which seriously affects the later operation of the b...
