Abstract
The utility model relates to a structure of making an uproar falls in winter protection of EMUs automobile body flat top belongs to EMUs automobile body flat top structure. Sound insulation felt no. 1, glass cotton, aerogel blanket insulation, inhale two orders on sound material and the sound insulation felt and meet and form five layer structures, the fine cloth of the outside cladding black glass of this five layer structure, winter protection nail and the five wrap -around layer structure cross -under of the fine cloth of black glass, the head of a nail and the automobile body top below of this winter protection nail connect through the structure is sticky, and the gasket cup joints in the below that the winter protection was followed closely. The advantage is novel structure, and the external noise of propagating of effectively isolated train running in -process is showing the assimilation effect of the noise that produces, has promoted overall structure's fire behavior, is applied to top in the train, and the mode that wholly adopts the winter protection nail to bond is fixed, plays the winter protection and falls the heat retaining effect of making an uproar.
Description
Technical field
The utility model belongs to Motor train unit body flat-tope structure, refers in particular to the car body flat-tope structure of the cold-proof noise reduction of energy.
Background technology
Train is in operation and can produce very big noise, when running in north cold area, the heat-insulating property to train requires high simultaneously, the material used on existing car body belongs to single layer structure more, the adhesive bonding with car body does not the most have fire protecting performance, it is difficult to ensure effectively reducing and the isolation of low temperature to external world, simultaneously because the fire protecting performance difference of bonding agent also causes having there is certain potential safety hazard of noise simultaneously.
Summary of the invention
The utility model provides a kind of cold-proof denoising structure of Motor train unit body flat-top, the problem bad to solve the cold-proof noise reduction of Motor train unit body top existence.
The utility model adopts the technical scheme that: sound-insulating felt one, mineral wool, aerogel heat-insulating blanket, sound absorber and sound-insulating felt two formation connected in order five-layer structure, this five-layer structure outside cladding black glass-fiber-fabric, the five-layer structure cross-under that cold-proof nail is coated with black glass-fiber-fabric, the head of a nail of this cold-proof nail is bonding by structure glue with below car body top, and pad is socketed in the lower section of cold-proof nail.
The utility model has the advantages that novel structure, sound-insulating felt has the sound insulation property of excellence, the effectively extraneous noise propagated during isolation train driving, its surface of sound absorber and the pore structure of inside, notable to the assimilation effect of the noise produced, the thermal conductivity factor of aerogel heat-insulating blanket is extremely low, train effectively intercepts Conduction At Low Temperature when cold zone runs, keep vehicle body heat not run off simultaneously, the thermal conductivity factor of mineral wool is superior, it it is the heat-insulating material of known function admirable, fire proof construction glue is as the adhesive of bonding cold-proof nail, adhesive strength is big, and due to its fire protection flame retarding, improve integrally-built fire protecting performance, it is applied to top in train, the overall mode using cold-proof nail bonding is fixed, play the effect of cold-proof noise reduction insulation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Sound-insulating felt 1, mineral wool 3, aerogel heat-insulating blanket 4, sound absorber 5 and sound-insulating felt 26 formation connected in order five-layer structure, this five-layer structure outside cladding black glass-fiber-fabric 9, the five-layer structure cross-under that cold-proof nail 8 is coated with black glass-fiber-fabric 9, the head of a nail of this cold-proof nail is bonding by structure glue with below car body 1 top, and pad 7 is socketed in the lower section of cold-proof nail.
Claims (1)
1. the cold-proof denoising structure of Motor train unit body flat-top, it is characterized in that: sound-insulating felt one, mineral wool, aerogel heat-insulating blanket, sound absorber and sound-insulating felt two formation connected in order five-layer structure, this five-layer structure outside cladding black glass-fiber-fabric, the five-layer structure cross-under that cold-proof nail is coated with black glass-fiber-fabric, the head of a nail of this cold-proof nail is bonding by structure glue with below car body top, and pad is socketed in the lower section of cold-proof nail.
