Abstract
A floating-constructed in-built floor structure of a subway vehicle comprises a vehicle body floor and an aluminum honeycomb floor. The inner area of the aluminium honeycomb floor falls upon the vehicle body floor through a rubber blanket, and the edge of the aluminium honeycomb floor is fixed through a rubber block with a bolt on the vehicle body floor. The rubber block is fixed in a groove in the upper surface of the vehicle body floor, and the head of the bolt is fixed in the rubber block in a vulcanized mode or embedded in the rubber block. A bolt rod of the bolt penetrates through the aluminium honeycomb floor, and the aluminium honeycomb floor is elastically fixed on the vehicle body floor through a nut. According to the scheme, the original damping structure that the rubber block is arranged between the aluminium honeycomb floor and the vehicle body floor is reserved, and the connecting bolt is embedded or fixed in the rubber block in the vulcanized mode in advance, so that metal connection between the aluminium honeycomb floor and the vehicle body floor is completely avoided, and the same damping effect as the rubber block is achieved.
Description
Technical field
The present invention relates to that a kind of railcar is floating builds in-built floor panel structure, belong to the in-built design field of guideway vehicle.
Background technology
Along with the sharply expansion of urban population, city traffic is had higher requirement, railcar is large with its freight volume, start and stop rapidly, safety on schedule, the feature of smokeless environment-friendly, be developed rapidly in each big and medium-sized cities, wide market.
The floor board mounting structure of current metro industry vehicle as
figureshown in 1, by rubber pad 3 damping between aluminum honeycombfloor 2 and car body floor 1, but directly connected by bolt 4 between aluminum honeycombfloor and car body floor, inevitably by car body floor vibration passing on aluminum honeycombfloor.
figurein 1, skirting 6, is installed on section bar mount pad 5 by bolt.
Summary of the invention
Technical matters to be solved by this invention is, overcomes the above-mentioned shortcoming of prior art, provides a kind of railcar to float and builds in-built floor panel structure.
In order to solve above technical matters, railcar provided by the invention is floating builds in-built floor panel structure, composition comprises: car body floor, aluminum honeycombfloor, described aluminum honeycombfloor interior zone drops on car body floor by rubber pad, the edge of described aluminum honeycombfloor is fixed by the rubber block with bolt be arranged on car body floor, and described rubber block is fixed on car body floor
upper tablein the groove in face, the head sulfuration of bolt is fixed or is embedded in rubber block, and the screw rod of bolt through aluminum honeycombfloor, and is fixed on elastomeric for aluminum honeycombfloor on car body floor by nut.
The present invention also has following improvement:
1, railcar of the present invention is floating builds in-built floor panel structure, also has skirting, and the lower end of described skirting is fixed on aluminum honeycombfloor by flathead screw
upper tableface, lower end is connected with framed side wallboard.
2, described rubber pad is embedded in and is located at car body floor
upper tablein the groove in face.
This programme remains the shock-damping structure arranging rubber block between primary aluminum honeycomb floor and car body floor, but is embedded in advance by tie bolt or fluidisation is fixed in rubber block, makes to completely avoid metal between the two and connects, reach the damping effect equal with rubber block.

upper tablerubber pad 3 in the C type groove groove of face drops on car body floor 1, and the edge of aluminum honeycombfloor 2 is fixed by the rubber block 7 with bolt be arranged on car body floor 1, and rubber block 7 is fixed on car body floor 1
upper tablein the C type groove in face, the head sulfuration of bolt is fixed or is embedded in rubber block 7, and the screw rod of bolt through aluminum honeycombfloor 2, and is fixed on elastomeric for aluminum honeycombfloor 2 on car body floor 1 by nut.Car body floor 1 and rubber pad 3 and rubber block 7
upper tablescribble glue between face, by glue, car body floor 1 is fixed on car body floor 1.
As
figurerailcar of the present invention shown in 2 is floating builds in-built floor panel structure, also has skirting 6, and the lower end of described skirting 6 is fixed on aluminum honeycombfloor 2 by flathead screw
upper tableface, lower end is connected with framed side wallboard.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of application claims.
