Embodiment Construction

[0024] Hereinafter, the concrete vibration-absorbing structure according to the preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0025] see figure 1 Referring to FIG. 4 , the vibration-absorbing structure 200 is placed on the roadbed 242 . The roadbed 242 is mainly made of concrete material. The vibration damping structure 200 has a structure body 210 . The structure body 210 includes a substrate 210a, a first sidewall 211, a second sidewall 211a and a third sidewall 211b. The first side wall 211 and the second side wall 211a are substantially parallel to each other. The third side wall 211a is connected to ends of the first side wall 211 and the second side wall 211a. A seating space 212 is enclosed between the first side wall 211 , the second side wall 211 a and the third side wall 211 b. A positioning protrusion 214 is formed at the central portion of the bottom of the structure body 210 . The fir...

Abstract

The present invention discloses a vibration eliminating structure for concrete sleeper. In the vibration eliminating structure, a structure has two parallel side walls and another side wall which is mounted on the roadbed and forms a retainer space among the side walls. A first vibration eliminating component is tightly attached to each side walls for absorbing level vibration transmitted from the sleeper. The first vibration eliminating component is made of elastic materials. A second eliminating component is also made of elastic materials and is tightly attached to a first frame, a second frame and a third frame. The vibration eliminating structure can prevent foreign objects falling into the retainer space from the roadbed by adopting the structure.

Description

technical field [0001] The invention relates to a vibration-absorbing structure for concrete sleepers, which can absorb and attenuate horizontal and vertical vibrations caused by dynamic loads such as electrified trains or other trains. Background technique [0002] Generally, a vibration-absorbing structure for a concrete sleeper includes a structure body and a shock-absorbing pad. The structure is installed into a seat groove cut in the surface of the subgrade. The shock-absorbing pad is installed in a seat space in the structure. The sleeper is arranged on the shock-absorbing pad of the vibration-absorbing structure. Rails are laid on sleepers. [0003] For such prior art, when an electrified train passes along the steel rail, a vertical load and a horizontal load will act on the sleepers and shock-absorbing pads. The cushioning force of the shock-absorbing pad absorbs vertical loads. Therefore, ordinary concrete sleepers cannot withstand the vibration and shock of e...
