Description

Eliminate secondary noise's sound barrier connection structure

Technical Field

The utility model relates to an equipment field of making an uproar falls, specific eliminate sound barrier connection structure of secondary noise that says so.

Background

The high-speed motor train can generate larger wind noise and rail noise during running, and has larger influence on the environment, the physical and mental health, so that the high-speed railway is usually provided with a sound barrier through people living areas such as villages, towns and the like. The sound barrier is formed by combining a plurality of barrier plates, upright columns and isolated rubber strips, and is vibrated, loosened and deformed to generate secondary noise under the impact of strong airflow when a motor vehicle passes through. The damping adhesive tape is aged and hardened and loses elasticity due to wind blowing and sunshine, the damping function is weakened, the vibration noise of the barrier plates is enhanced, and meanwhile, gaps occur between the barrier plates and the stand columns to generate larger secondary noise.

Disclosure of Invention

The utility model aims to solve the technical problem that overcome prior art not enough, provide an eliminate secondary noise's sound barrier connection structure, the utility model provides a technical scheme that its technical problem adopted is: the utility model discloses a structure includes shaped steel stand A, shaped steel stand B, fixing base A, fixing base B, sound barrier, elastomer, rubber strip A, rubber strip B, its characterized in that fixing base A top sets up shaped steel stand A, shaped steel stand A and fixing base A formula structure as an organic whole, fixing base B top sets up shaped steel stand B, and shaped steel stand B and fixing base B formula structure as an organic whole place the sound barrier between shaped steel stand A, the shaped steel stand B, and sound barrier both ends bottom meets with fixing base A, fixing base B respectively, the edge sets up rubber strip A, rubber strip B between sound barrier and the shaped steel stand A, constitute a top opening between shaped steel stand A, fixing base A, sound barrier, rubber strip A, the rubber strip B, closed space all around, set up the elastomer in it.

Preferably, the shape of the section steel upright A and the shape of the section steel upright B are H-shaped.

Preferably, the sound barrier, the rubber strip A and the rubber strip B arranged at the section steel upright post A on the fixing seat A have the same structure as the section steel upright post B on the fixing seat B.

Preferably, the elastomer is formed by solidifying elastomer fluid raw materials which are formed by mixing a prepolymer obtained by polymerizing polyether and MDI and a polymer and a chain extender.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model discloses novel structure, the utility model discloses a shaped steel stand and sound barrier are connected to the elastomer, and elastomer and each subassembly bonding strength far above the interfacial stress between, and elastomer restorable is out of shape, and the displacement that the absorbent structure vibration produced eliminates the secondary noise of sound barrier.
