Description
Technical field
The utility model is related to a kind of novel floor structures, are wanted more particularly, to a kind of fire protecting performance, sound-proofing, comfort
Seek high floor panel structure.
Background technology
The fire savety of modern subway, sound-proofing, comfort etc. require increasingly to obtain the attention of subway owner.
Currently, floor of railway vehicle structure all cannot be satisfied southern Hong Kong metro project industry in terms of fire protecting performance, sound insulation value and rigidity
Main requirement, research is a kind of, and to meet the floor panel structure that fire protecting performance is good, sound insulation value is high, rigidity is big imperative.
Utility model content
The purpose of this utility model is to provide a kind of rail vehicle novel floor structure, fire protecting performance is good, sound insulation value is high,
Rigidity is big, to meet the requirement of southern Hong Kong metro project owner.
To achieve the above object, the utility model provides a kind of novel floor structure, including PVC floor cloth, floorboard, subtracts
Shake pad, aluminium section bar bearing beam, it is characterised in that：Floorboard is phenolic resin composite floor board, the space between the aluminium section bar bearing beam of floor
It is a kind of composite sandwich structural, upper following table to add glass silk flosssilk wadding and the heat-insulated material of ceramic fibre, the phenolic resin composite floor board
Layer is compound using phenolic resin glass fibre, and middle layer is wood materials, and phenolic resin composite floor board is clipped in PVC floor cloth and glass
Between glass silk flosssilk wadding layer, ceramic fibre is below glass silk flosssilk wadding.
Floorboard uses phenolic resin composite floor board in the utility model, has excellent fire protecting performance, excellent attraction
Ability, high strength/weight ratio, water absorption rate are low.In floor panel structure between each bearing beam space addition glass silk flosssilk wadding and ceramic fibre every
Hot material has good heat-blocking action, has great role to fire protecting performance raising.Prove that this place is hardened through SGS laboratory tests
Structure can reach BS6853 integralities, thermal insulation, Fire Test requirement in 45 minutes.Phenolic resin floor employed in structure, phenolic aldehyde
Resin floor itself has good sound insulation value.Noise requirements meet BS/EN/ISO 3381-2005 and BS/ISO 3095-
2005, the weighted sound transmission loss on floor itself reaches Rw=32dB, has excellent sound-insulation capability.Each floor is in floating type
State, floor are not rigidly connected with steel underframe, and passenger's walking comfort is good.
Description of the drawings
Fig. 1 is the floor panel structure vehicle body longitudinal direction sectional view of the utility model；
Fig. 2 is the floor panel structure width of the carbody sectional view of the utility model；
Fig. 3 is that the phenolic resin in the utility model meets floor internal view.
Wherein 1, PVC floor cloth；2, phenolic resin composite floor board；3, screw；4, connecting plate；5, gap filler；6, beam；
7, glass silk flosssilk wadding；8, small density ceramic fiber；9, big density ceramic fiber；10, structure glue；11, bearing beam；12, surface layer is highly dense
It spends glass fibre and phenolic aldehyde modeling ester is compound；13, core material Ba Shamu；14, edge sealing is that low density glass fiber and phenolic aldehyde are moulded ester and answered
It closes.
Specific implementation mode
Referring to Fig.1, Fig. 2, Fig. 3, the utility model include PVC floor cloth 1, phenolic resin composite floor board 2, beam 6, aluminium
Proximate matter bearing beam 11, floorboard use phenolic resin composite floor board.Phenolic resin composite floor board has excellent fire protecting performance.Phenolic aldehyde tree
Fat floor is a kind of composite sandwich structural, and upper layer is compound using phenolic resin glass fibre, and surface layer 12 is high-density glass
Fiber and phenolic aldehyde modeling ester are compound, and middle layer is Ba Sha wood 13, and edge sealing 14 is that low density glass fiber and phenolic aldehyde modeling ester are compound.Phenol
Urea formaldehyde floor has outstanding fire protecting performance；Excellent attraction power；High strength/weight ratio；Water absorption rate is low.Due to floorboard
The entire interior chassis part of covering, its fire protecting performance play a decisive role.Add glass in space between each aluminium section bar bearing beam 11
Silk flosssilk wadding 7 and the different ceramic fibre 8 of density, 9 heat-insulated materials, ceramic fibre 8,9 density are different, only therebetween in contrast.
Ceramic fibre is added inside steel underframe corrugated steel trough, the heat-insulated material of ceramic fibre has good heat-blocking action, right
Fire protecting performance raising has great role.Prove that this floor panel structure can reach BS6853 integralities, thermal insulation through SGS laboratory tests
Fire Test requirement in 45 minutes.This floor panel structure is most excellent one of the floor panel structure of current domestic fire protecting performance.
There is good sound insulation value on phenolic resin floor employed in this floor panel structure, phenolic resin floor itself.Noise
It is required that meeting BS/EN/ISO 3381-2005 and BS/ISO 3095-2005, the weighted sound transmission loss on floor itself reaches Rw=
32dB.Integral floor system structure weighted transmission loss：Rw=48dB has excellent sound-insulation capability.
This floor panel structure various regions plate is in quick condition, and floor is not rigidly connected with steel underframe.Simultaneously under floor
Square beam material is medium hardness silica gel, and passenger, which walks above, certain elasticity, can reduce feeling of fatigue when walking.And it is traditional
Domestic project floor is to be bolted with steel underframe, for rigid connection；Floor supported underneath is high durometer rubber block, tradition
Floor panel structure passenger's walking comfort is good without this floor panel structure.
