Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
A part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill people
The every other embodiment that member is obtained on the premise of not making creative work, broadly falls into the scope of protection of the invention.
As it is shown in figure 1, a kind of train floor that the embodiment of the present invention provides, including hollow material 1, specifically, this enforcement
The centre of example hollow material 1 includes multiple die cavity, and die cavity is separated to form by multiple vertical reinforcements 11.Hollow material 1
Being preferably aluminium section bar in embodiment, lightweight, intensity is high.The side of hollow material 1 is interval with multiple grafting pedestal 2, hollow
Section bar 1 is provided with the side of grafting pedestal 2 and is located at and the fixing aluminium sheet 3 of grafting pedestal 2, between leaving between aluminium sheet 3 and hollow material 1
Gap.The train floor that the embodiment of the present invention provides includes hollow material 1 and leaves the aluminium sheet 3 in gap, hollow with hollow material 1
Leaving gap between section bar 1 and aluminium sheet 3 and improve damping and the sound-insulation capability on floor, the hollow material 1 of this train floor is suitable
In two-layer plate, add that aluminium sheet 3 forms three ply board part structure and improves non-deformability.And can be by reducing hollow material
The thickness of 1, the gross thickness making this train floor is identical with the floor thick-ness that train in prior art uses so that it is can pacify smoothly
Dress.The train floor that the embodiment of the present invention provides is particularly suited for bogie region, reduces noise, improves and takes the comfortable of train
Property.In the present embodiment, in the middle part of hollow material 1, reinforcement 11 is set to vertical reinforcement 11, and simple in construction is easy to molding.And
In actual application, the thickness of this hollow material 1 is less, and the vertical reinforcement 11 of setting is enough to ensure that its intensity.
Further, in the present embodiment, the surface mount of aluminium sheet 3 has vibration-absorptive material 4.Further, damping in the present embodiment
Material 4 is elastomeric material.Vibration-absorptive material 4 can also be the material of other dampings that can absorb sound such as polyurethane foam.The present embodiment
Middle employing elastomeric material can be bonding with aluminium sheet 3 by the way of hot melt.Arrange vibration-absorptive material 4 layers can absorb further and make an uproar
Sound, promotes sound-insulation capability.Preferably, in the present embodiment, vibration-absorptive material 4 is pasted on the aluminium sheet 3 side near hollow material 1.Certainly
Vibration-absorptive material 4 can also be arranged on aluminium sheet 3 and deviate from the side of hollow material 1, but there may be the equivalent risk that easily drops, for
Vibration-absorptive material 4 and the fixing requirement height of aluminium sheet 3, therefore, be preferably arranged on aluminium sheet 3 near hollow material 1 in the present embodiment
Side.
Further, in the present embodiment, grafting pedestal 2 includes the riser 21 vertical with hollow material 1 and is located at riser 21
The rib 22 of both sides, the side that aluminium sheet 3 deviates from hollow material 1 towards the side of hollow material 1 with rib 22 contacts.Bayonet base
The rib 22 that seat 2 is arranged ensure that high unity when aluminium sheet 3 is fixed, it is ensured that the flatness of this train floor.Specifically, originally
In embodiment, grafting pedestal 2 uses extruded with hollow material 1.Grafting pedestal 2 is one-body molded with hollow material 1, simplifies
Preparation technology.
Further, in the present embodiment, hollow material 1 is provided with polylith, and polylith hollow material 1 uses welding to connect.In due to
The compact dimensions of casement material 1 limits, and needs to arrange polylith hollow material 1 the most in use and is spliced so that it is meets train
Floor covering layers area requirements.Owing to aluminium sheet 3 can be shaped to sufficiently large area, so general aluminium sheet 3 only uses one piece i.e.
Can.
Further, in the present embodiment, aluminium sheet 3 is provided with the fluting 31 corresponding with grafting pedestal 2, aluminium sheet 3 and bayonet base
Seat 2 uses transposition section weldering to connect.Aluminium sheet 3 welds with grafting pedestal 2, Stability Analysis of Structures, and bonding strength is high.It should be noted that aluminum
Fixing being not limited between plate 3 with grafting pedestal 2 is welded, it is also possible to be riveting, and screw is fixing waits other connected modes.
In the embodiment of the present invention, train floor gross thickness is preferably 30mm, and aluminium sheet 3 is preferably 2.5mm5083-0 aluminium sheet 3,
The floor taking 2500mm length carries out non-deformability simulation calculating, and in the case of average applying 1N stress, deflection is
11.3mm, and under same test condition, two-layer floor deformation amount of the prior art is 14.1mm, it can thus be seen that the present invention
The train floor non-deformability that embodiment provides is promoted.The train floor that the embodiment of the present invention is provided and prior art
Middle two-layer floor carries out oise insulation factor simulation, as seen from Figure 6, higher than under most of noise frequency of 400HZ, and the embodiment of the present invention
The train floor sound-insulation capability provided is better than two-layer floor (except 800HZ) of the prior art, and particularly noise frequency is higher than
After 1600HZ, the oise insulation factor that the embodiment of the present invention provides is substantially better than prior art.And along with train speed improves, noise frequency
Also can improve.After train speed is more than 300km/h, noise is more than 2000HZ, so the train floor that the embodiment of the present invention provides
Defening effect is more preferable.
The embodiment of the present invention additionally provides the manufacture method of a kind of above-mentioned train floor, comprises the following steps:
S1, extruding forms the hollow material 1 with grafting pedestal 2；
S2, at the surface mount vibration-absorptive material 4 of aluminium sheet 3；
S3, arranges fluting 31 on aluminium sheet 3 and vibration-absorptive material 4；
S4,31 grafting corresponding with grafting pedestal 2 of slotting, and make vibration-absorptive material 4 be located towards the side of hollow material 1；
S5, welds aluminium sheet 3 with grafting pedestal 2.
Last it is noted that above example is only in order to illustrate technical scheme, it is not intended to limit；Although
With reference to previous embodiment, the present invention is described in detail, it will be understood by those within the art that: it still may be used
So that the technical scheme described in foregoing embodiments to be modified, or wherein portion of techniques feature is carried out equivalent；
And these amendment or replace, do not make appropriate technical solution essence depart from various embodiments of the present invention technical scheme spirit and
Scope.
