Abstract
The utility model relates to a car manufacturing in the field of the traffic and transportation, in particular to a wagon floor used by trolley coaches and highway automobiles. The realized method of the utility model is that: the glue lines are coated on the base plate used as the surface layer and one side of the panel, the foamed aluminum plate used as the sandwich is arranged between the two glue lines, and the foamed aluminum wagon plate forms after being heated and pressed. Making use of the foamed aluminum wagon plate not only effectively obstructs the noise and the shock transferred to wagons by the track and the pavement and improves the comfort of the passengers but also relieves the gravity of the car body. Simultaneously, the foamed aluminium wagon floor has strong ageing resistance, high intensity and uneasy burn, which is a new materials with safety and environmental protection.
Description
Technical field the utility model relates to vehicle manufacturing, especially trolley coach and the employed floor compartment of on-highway motor vehicle of traffic and transport field.
Background technology current track passenger car floor generally adopts between two-layer wooden plywood or aluminium sheet filling slackness wool and inorganic fibre to make, and its sound insulation and isolating affection are relatively poor.Along with railway speed increase, the wheel of high speed train and rail bump are fierce more, and the noise of generation is big, vibrations are also strong; And people are also more and more higher to the comfort level requirement of travelling, and therefore sound insulation and the isolation property to the passenger train floor requires to improve day by day.Although damping sound insulation situation improves to some extent after adopting filling fiber and the organic damping material of coated, effect is unsatisfactory, and the organic damping material that adopts is unfavorable for fire prevention.
The floor compartment of on-highway motor vehicle has experienced the development course from floorboards of wood, bamboo adhesive floor, PVC plastic floor to the jewel steel floor, but it is few all to be subjected to resource, poor performance, the restriction that price is expensive.CN2456900Y has announced a kind of " High Performance passenger vehicle fire prevention composite floor board ", it is made up of high performance inorganic complex material fire prevention surface layer and the various light heat insulating material laminboard layers that are clipped between surface layer, wherein, light heat insulating material is foamed plastic, wooden and fiber and other material, but the intensity of this material is low, and sound insulation damping and fire resistance are poor.
Summary of the invention invention the purpose of this utility model is to provide a kind of intensity height, sound insulation good damping effect, the floor compartment of fire safety.
Realize that mode of the present utility model is as follows: a kind of foamed aluminium floor compartment, comprise superficial layer and laminboard layer, being coated with upper glue layer as the base plate of superficial layer and a side of panel, again the foamed aluminium board as laminboard layer is placed between two glue-lines, add and form the foamed aluminium floor compartment after the hot pressing.
Base plate and panel as superficial layer can be selected aluminium sheet for use, and thickness is between 0.5～2.0mm.
Base plate and panel as superficial layer also can be selected steel plate for use, and thickness is between 0.3～1.0mm.
Equally, can also select other metallic materials such as coloring zinc plate for use as the base plate and the panel of superficial layer.Perhaps, base plate is selected metallic material for use, and panel is selected non-metallic material for use.
In order to adapt to operating needs, can make marginal portion bending earlier as the foamed aluminium board of laminboard layer, and then bonding with base plate with same shape and panel, the foamed aluminium floor compartment marginal portion that makes can form radian.Simultaneously, the foamed aluminium floor compartment that makes can cut randomly according to actual needs.
The foamed aluminium board that the foamed aluminium floor compartment is used prepares with the direct foaming of melt mass method.The foamed aluminium material specification that this method is made is bigger, the standard foam aluminium plate of the long 1800mm * wide 800mm that uses on can manufacture, and the thickness of sheet material can cut according to customer requirement, and general thickness is between 10～200mm.The foamed aluminium material of foam melt method production is a closed pore foam aluminium, and density is at 0.2～0.8g/cm
3Between, the aperture is 1～8mm, is that matrix alloy is prepared with fine aluminium, aluminum alloy or aluminum matrix composite.
Closed-cell aluminum foam is a kind of Multifunction material, and it is the porous material that is distributed with countless discrete bubbles each other in metallic aluminium matrix inside.The irregularity of bubble and the three-dimensional homogeneity that distributes thereof give foamed aluminium many excellent characteristic, such as energy-absorbing buffering, mechanical damping etc., especially have good sound absorption characteristics.It is good that foamed aluminium also has a resistance to aging, good heat resistance, and the non-volatile poisonous or pernicious gas of proper intensity, chance fire, characteristics such as non-hygroscopic.Therefore, the use of foamed aluminium floor compartment not only can intercept noise and the vibrations that transmit on track and road surface effectively in the compartment, improves the traveling comfort of taking, and can alleviate car body deadweight, the safety that improves moving velocity and take.
Description of drawings Fig. 1 is the structural representation of foamed aluminium floor compartment.
The specific embodiment is elaborated to structure of the present utility model below in conjunction with specific embodiment.
It is material that base plate 1 and panel 2 are selected aluminium sheet for use, and size and foamed aluminium board 3 are complementary, and thickness is 1.0mm, is coated with upper glue layer 4 in their side; The foamed aluminium board 3 of aluminium alloy preparation, its planar dimension is 1800mm * 800mm, and thickness is 25mm, and the aperture is 3～5mm, and density is 0.5g/cm
3, foamed aluminium board 3 is placed between two glue-lines 4, promptly making the foamed aluminium floor compartment after the compacting on the hot press.During installation, can carry out cutting as required; Perhaps propose specification requirement, carry out special facture according to demanding party.
It is material that base plate 1 and panel 2 are selected steel plate for use, and size and foamed aluminium board 3 are complementary, and thickness is 0.5mm, is coated with upper glue layer 4 in their side; Select the foamed aluminium board 3 of fine aluminium preparation for use, its planar dimension is 1800mm * 800mm, and thickness is 30mm, and the aperture is 4～6mm, and density is 0.4g/cm
3, foamed aluminium board 3 is placed between two glue-lines 4, promptly making the foamed aluminium floor compartment after the compacting on the hot press.During installation, can carry out cutting as required, perhaps propose specification requirement, carry out special facture according to demanding party.
