Abstract
The utility model relates to a railway vehicle sound insulating floor. The floor includes a solid wood floor layer, a veneer layer and a metal plate layer up and down in sequence; the middle of the veneer layer is provided with a layer of sandwich of sound insulating material. The sound insulating floor has a simple structure, and is convenient to be installed; the metal plate layer and the internal sound insulating material at the lower part of the sound insulating floor have excellent sound insulating effects; the sound insulating material generates effective reflection effect on the sound under the vehicle, and also has the damping effect, consumes sound wave energies through self shaking, ensures the sound insulating and damping effects of the whole structure of the floor and guarantees the internal comfort. In addition, use of solid wood floor also leads the internal style of the passenger compartment of the railway vehicle to present a new appearance, greatly improves the luxurious, slap-up, comfortable and beautiful performances of vehicles, and meets the higher and higher requirements of the passengers on the environments of the passenger compartment.
Description
Technical field
The utility model relates to a kind of rolling stock equipment, and particularly a kind of Sound insulation floorings that uses on rolling stock belongs to the railway vehicle device technical field.
Background technology
Traditional vehicle interior floor adopts laminated structure, is to cover one deck colloid floor cloth on plywood caul, and this floor panel structure all can not satisfy passenger's requirement more and more higher to vehicle environment at aspects such as vision and comfort levels.
In addition, continuous speed-raising along with rolling stock, vibration during vehicle operating and noise aggravation, coupling situation rolling stock complexity before, the noise that existing flooring material is produced in the time of can not stopping vibration of car body external device and vehicle operating preferably, so need to adopt the better Sound insulation floorings of soundproof effect, improve the vehicle sound insulation value.
In order to improve the soundproof effect on floor, the following several schemes that adopt are also arranged in the prior art, one is to be 200520036339.3 described " maglev vehicle compartment composite floor boards " as the patent No., and this floor is by two layers of thin up and down and a high-strength metallic material panel and a middle bed thickness and the foam core material of lightweight is formed monolithic composite panel sandwich structure.Another is to be 200810249837.4 described " a kind of bus decks with sound insulation and decrease of noise functions " as the patent No., and this floor is followed successively by from top to bottom: flooring laminate layer, damping glue flaggy, doubling plank layer, the cotton layer of MULTILAYER COMPOSITE noise reduction, steel plate layer, from skinning cellular rubber layer.What these several schemes all adopted is the multi-layer composite floor structure, has certain sound insulation effect, but its complex structure, and also the aesthetics of interior and comfort level are all slightly not enough.
Summary of the invention
The utility model main purpose is to address the above problem and is not enough, provide a kind of comfortable attractive in appearance, and sound insulation value is good, rolling stock Sound insulation floorings simple in structure, easy for installation.
For achieving the above object, the technical solution of the utility model is:
A kind of rolling stock Sound insulation floorings, this floor comprise solid wooden floor board layer, layer of plywood and sheet-metal layers from top to bottom successively, are provided with the interlayer of one deck sound insulation material in the centre of described layer of plywood.
Described sheet-metal layers is a steel plate, closely pastes with sealant between described solid wooden floor board layer and the layer of plywood.
Content to sum up, rolling stock Sound insulation floorings provided by the utility model, adopted composite floor board structure at layer of plywood therebetween one deck sound insulation material and the one solid wooden floor board layer of sealing stickup thereon, simple in structure, and it is easy for installation, the sheet-metal layers and the inner sound isolation material of its bottom have good soundproof effect, the sound insulation material is when producing usable reflection to noise under the car, also take into account shock damping action, vibrations by self consume acoustic wave energy, guarantee floor integrally-built sound insulation damping effect, guarantee the interior comfort level.It is fresh and new that the use of solid wooden floor board also makes the inner style of railway car in addition, improved performance luxurious, high-grade, comfortable, attractive in appearance greatly, satisfies passenger's requirement more and more higher to vehicle environment.
Description of drawings
Fig. 1 section structure scheme drawing of the present utility model.
As shown in Figure 1, solid wooden floor board layer 1, layer of plywood 2, sheet-metal layers 3, sound insulation material 4.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As shown in Figure 1, a kind of rolling stock Sound insulation floorings, this floor comprises solid wooden floor board layer 1, layer of plywood 2 and sheet-metal layers 3 from top to bottom successively, is provided with the interlayer of one deck sound insulation material 4 in the centre of layer of plywood 2.
Sheet-metal layers 3 adopts steel plate, adopts glue closely to paste between sheet-metal layers 3 and the layer of plywood 2, can effectively stop the noise that a part of car is outer.
The mat formation mode of solid wooden floor board of the paving mode of solid wooden floor board layer 1 and family is the same, adopts the mode of inserting of piecing together.Closely paste with sealant between solid wooden floor board layer 1 and the layer of plywood 2, can prevent the vibrations and the infiltration of solid wooden floor board like this, improve the luxurious degree of dress in the compartment, its aesthetics and comfort level all are higher than traditional colloid floor cloth far away.
Be provided with the interlayer of one deck sound insulation material 4 again in the centre of layer of plywood 2, be for isolated car body further outer noise, guarantee the comfort level in the car, the integral structure that layer of plywood 2 and sound insulation material 4 are formed in one, be convenient to the installation on floor in the compartment like this, simultaneously, help also guaranteeing that rolling stock is behind long-play, sound insulation material 4 is not damaged, thereby guarantees the effect of floor sound insulation and damping.Wherein, sound insulation material 4 is by its special composition, when noise under the car is produced usable reflection, also the vibrations by self consume acoustic wave energy, play the effect of damping, can guarantee floor integrally-built sound insulation damping effect not increasing under the prerequisite of plate thickness entirely like this.
As mentioned above, given in conjunction with the accompanying drawings and embodiments scheme content can derive the similar techniques scheme.In every case be the content that does not break away from technical solutions of the utility model, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of technical solutions of the utility model according to technical spirit of the present utility model
