Description

26 42817

  The present invention relates to a floor for containers and

  vehicle bodies in general. -

  Basically, traditional vehicle bodies consist of stamped metal plates or sheets of fiber

  molded that define the outline or configuration of vehicles.

  More specifically, the floors of these conventional bodies are also composed of stamped metal plates or molded fiber sheets, and there are also floors made entirely of wood or wood associated with fiber panels.

or metal.

  Although they are produced and used in this traditional way, known floors have a number of

  disadvantages directly detrimental to the entire vehicle.

  Conventional floors formed from stamped metal plates have the disadvantage of offering relative mechanical strength and low weather resistance, generally offset by specific treatments and coatings applied to the plates or

panels already stamped.

  However, it can happen that when floors composed of metal sheets receive external shocks due for example to projections of gravel on road traffic lanes, these shocks cause a deformation which alters at least the surface treatment or coating, thus creating a point of easy development of rust which over time degrades the entire floor, irreversibly. Another disadvantage of these metal floors or backgrounds lies in the significant noise factor that they produce under the effect of external shocks: there is no appropriate soundproofing and the noise of external shocks suffered is therefore transmitted to the interior of the cabin

  and / or the vehicle body.

  Conventional molded fiber floors offer good weather resistance, but they do not have adequate mechanical strength or satisfactory soundproofing, which creates a number of problems inside the cabin and even in

  bodies of freight vehicles.

  Floors made of wood and sheets of fiber or metal have the same disadvantages, since the wood used

  as structural part is subject to irreversible deformations and exposed to the attack of bad weather, a significant humidity involving

its decay.

  One of the objects of the present invention is to provide a floor for containers and for vehicle bodies in general which is not affected by external shocks and which offers a high degree of

  mechanical resistance to load.

  The invention also aims to provide a floor

  waterproof and very weather resistant.

  Another object of the invention is to provide a floor for containers and for vehicle bodies in general which has a high degree of noise absorption and which does not transmit inside.

  from the passenger compartment or body of the vehicle impact noise.

  Finally, the present invention aims to provide a floor of this type for containers and vehicle bodies in general which is not subject to wear or mechanical deformation and which offers

  therefore an overall longer service life.

  These objects and advantages, as well as other objects and advantages of the present invention, will now be achieved by means of a floor for containers and vehicle bodies in general, which comprises a plate or a panel composed of at least one central layer or core in

  metal wire and at least one layer of self-hardening material.

  It should be noted that the layers which form the plate can be obtained from specific raw materials or by recycling waste materials, as the brand teaches, for example, the process of recovering and reusing treads armed with wire. steel from piles of tire debris, a process which is described in the patent application filed by the same applicant on the same date as the present application and which makes it possible to obtain several treads 3ó armed with steel defining the central layer of metallic wire used

in the composition of the floor.

  By applying this construction concept to floors for containers and vehicle bodies, we will obtain a floor with high mechanical resistance, low noise level thanks to greater shock absorption, and considerably increased weather resistance, thus guaranteeing the floor Consequently

  container or vehicle body long life.

  Other purposes, advantages and features of this

  invention will become more apparent from the detailed description

  following of a preferred embodiment thereof, given by way of non-limiting example with reference to the accompanying drawing, the single figure of which schematically represents a perspective view, with partial cutaway, of a portion of a floor for container or

vehicle body.

  According to this single representation, the floor for a container or vehicle body comprises a plate 10 formed by a coated metal core 1 composed of several treads reinforced with steel recovered from tire debris or metal wire impregnated with rubber, said metal core 1 being placed between two layers of curable material 2 such as rubber, resin, thermoplastic material, etc., then covered with two layers of fragmentary material 3 impregnated with curable material 4, in particular rubber, which fragnentary material 3 is formed of small pieces of metal wire, synthetic wire or other wire, arranged randomly in the hardenable material 4 and offering a large

mechanical resistance.

  These layers 3, 4 are covered by a crosslinked reinforcement 5 impregnated or itself covered with another layer of curable material 6, in particular of rubber, said crosslinked reinforcement 5 being formed of strips or friezes of an elastically deformable material such

  only rubber, arranged between them so as to form a mesh.

  Finally, the two layers of cross-linked reinforcement 5 impregnated with rubber 6 are themselves respectively covered with two layers of hardenable material 7 which define the upper faces and / or

  bottom of finished floor or bottom 10.

  Although the preceding description has focused on a mode of

  preferred embodiment of the present invention, it is understood that

  this is not limited to the example described and illustrated here, and the man in the art will readily understand that it is possible to make various other changes and modifications relating to, for example, the number and nature of the constituent layers, without however go beyond the framework of

the invention.
