Description

SPECIFICATION A flooring material This invention relates to a flooring material and to a method of producing the flooring material. The flooring material is especially useful for livestock although it can also be used as a safety flooring for human use. The invention also relates to a livestock structure when including the flooring material and examples of livestock structures are wineries for pigs, stalls for cattle and pens for turkeys, ducks and chickens.
The floors of previously known livestock structures have been made of concrete or wood. Concrete floors are strong and durable and they can easily be cleaned by hosing down. The concrete floors are however disadvantageous in that they are cold, hard and abrasive. Wooden floors are hard to clean, they retain odours and they deteriorate readily in the presence of animal wastes. Furthermore, the wooden floors are not fire resistant. Both concrete and wooden floors can become slippery when wet, thereby giving a poor foothold to animals on them, especially new born or very young animals such for example as piglets. In the case of new born and young piglets, these animals have been known to starve to death simply because they have been unable to propel themselves towards their mother due to the floors being too slippery for them to gain adequate foothold.
It is an aim of the present invention to obviate or reduce the above mentioned disadvantages.
Accordingly, this invention provides a flooring material having a reticulated pattern of discrete apertures, the flooring material comprising a metal sheet having the discrete apertures, and a continuous coating of a plastics material which is permanently bonded to the metal.
This invention also provides a method of producing a flooring material having a reticulated pattern of discrete apertures, which method comprises providing a metal sheet having the discrete apertures, and permanently bonding a continuous coating of the plastics material to the metal.
This invention further provides a livestock structure having a floor and upstanding walls, the floor comprising a support arrangement and a flooring material which has a reticulated pattern of discrete apertures and which is positioned on the support arrangement, the flooring material comprising a metal sheet having the discrete apertures, and a continuous coating of a plastics material which is permanently bonded to the metal.
The flooring material is preferably one in which the apertures in the metal sheet are defined by connected metal strands, and in which the metal sheet is ground on both sides to remove high spots at the metal strand connections. Such metal grinding gives a flat metal surface at the points of the metal strand connections and this flat surface is less likely to wear through the plastics coating during use of the flooring material. Furthermore, the flat metal surfaces may be slightly softer for animals to stand on than more pointed surfaces. With unground metal strand connections, the high spots may be knife sharp but, after the grinding, they may perhaps be one-tenth of an inch wide.
Advantageously, the metal sheet is degreased and roughened to facilitate the permanent bonding of the plastics material to the metal sheet.
Preferably, the metal sheet is a sheet of expanded metal. Examples of other metal sheets are wire mesh, perforated metal sheets and chicken wire. The expanded metal sheet gives curved configurations over the flooring material, thus giving extremely good traction properties without the abrasive texture that is normally associated with good purchase. The good traction properties are especially evident to small hoofed animals such for example as swine.
The same curved configurations are also conducive to the elimination of liquid wastes from the flooring, thereby giving drier living conditions.
The metal sheet will usually be so coated with the plastics material that the apertures in the flooring material are defined by rounded plastics surfaces so that there are no crevices available for the unwanted retention of bacteria. Obviously, such rounded plastics surfaces enable the flooring material to easily be cleaned, for example simply by hosing down.
The metal sheet and the plastics material may be present in substantially equal weights. This ensures that the plastics material is of an adequate covering thickness.
Preferably, the plastics material is durable, nonabrasive, resilient, flame-retardant and resistent to attack by animal wastes and bacteria.
The plastics material is effective to protect the metal, for example from corrosion and rust. In addition, the plastics material acts to: (a) insulate the floor and so make the floor warmer to the sense of touch; (b) create a smooth non-abrasive, non-sharp surface; (c) remove any crevices in the metal which could harbour bacteria; and (d) provide a degree of resiliency in the flooring.
These additional qualities which are provided by the plastics material are all conducive to eliminating stress in livestock using the flooring, and it is this elimination of stress that makes for healthy, profitable livestock.
The method of the invention preferably includes the above mentioned feature of grinding the metal sheet on both sides to remove high spots at the metal connections prior to the permanent bonding of the continuous coating of the plastics material to the metal.
The method of the invention also preferably includes the above mentioned feature of degreasing and roughening the metal sheet prior to the permanent bonding of the continuous coating of the plastics material to the metal. The roughening is preferably effected by a method known as wheelabrating and which is somewhat similar to sandblasting. The wheelabrating can be effective to thoroughly clean the metal sheet, to roughen the surface of the metal sheet to provide a better grip for the plastics material, and to provide a slight dulling of any sharp edges of the metal sheet.
Advantageousiy, the metal sheet is pre-heated prior to the permanent bonding of the continuous coating of the plastics material to the metal.
In the method of the invention, the plastics material is preferably applied to the metal sheet in the form of a plastisol. Various plasticizers may be added to the plastics material. The method may be one in which the metal sheet is dipped in a horizontal position in the plastisol, in which the metal sheet is removed from the plastisol, and in which the plastisol on the metal sheet is cured in a tank containing a solution of one or more salts, with the metal sheet being maintained in a vertical position. If desired, the plastisol can also be cured with the metal sheet in the horizontal position. The salt solution is preferably a mixture of sodium and potassium nitrates. The curing is usually effected under heat and the salt solution enables fast curing times to be achieved since the salt solution is a far betterthermal conductorthan hot air.
Preferably, the metal sheet is removed from the plastisol in the horizontal position and before it is cured in the tank containing the salt solution it is rotated from the horizontal position both clockwise and anti-clockwise towards the vertical position. By way of example, it is mentioned that the metal sheet may be rotated from the horizontal position 80" towards the vertical in both the clockwise and the anti-clockwise directions, the total rotational movement of the metal sheet thus being 1600. The rotational movement of the metal sheet directly after it is removed from a tank containing the plastisol causes drips of plastisol that tend to drip from the metal sheet to run around the metal whilst they are still in a relatively liquid state.The drips thus level out, leaving a smoother and heavier coating on the underside of the metal sheet than may be obtained without the rotational movement. This underside of the metal sheet can then be used uppermost in use of the flooring material of the invention, although the difference in thickness and smoothness of the plastisol on both sides of the metal sheet is hardly visible to the naked eye.
The livestock structures of the present invention may be permanent, semi-permanent, or portable.
They may be provided with solid walls and a roof or merely meshed sides as in the case of pens. The support arrangement for the flooring material may be continuous, e.g. a concrete floor, or it may be discontinuous, e.g. in the form of joists or slats of wood, concrete or other material.
Embodiments of the invention will now be de scribed solely by way of example and with reference to the accompanying drawings in which; Figure 1 is a perspective view of expanded metal sheet for use in forming a flooring material in accordance with the invention; Figure 2 is a plan view of part of the flooring material; Figure 3 is a cross-section on the line 3-3 shown in Figure 2; Figure 4 is a cross-section showing a preferred expanded metal sheet for use in forming the flooring material of the present invention; Figure 5 shows the flooring material of Figure 2 positioned on a continuous support arrangement; and Figure 6 shows the flooring material of Figure 2 positioned on a discontinuous flooring arrangement.
Referring to Figures 1 to 3, there is shown a flooring material 2 having a reticulated pattern of discrete apertures 4. The flooring material 2 comprises an expanded metal sheet 6 which is shown most clearly in Figure 1 and which is provided with the discrete apertures 4. The apertures 4 are in effect defined by metal strands 8 which are interconnected at points 10. As will be seen from Figure 3, the metal strands 8 are inclined in the horizontal position and the points 10 of intersection of the strands 8 have pointed upper and lower ends 12,14 respectively.
As shown in Figures 2 and 3, the metal sheet 6 is provided with a continuous coating 16 of a plastics material which is permanently bonded to the metal.
The plastics material is bonded entirely around the metal strands 8 and it is arranged to form a substantially even coating over the metal sheet 6.
The plastics material gently curves around the apertures 4 in the metal sheet 6 so that the final shape of the apertures 4 will be as shown in Figure 2 in which they are gently elliptical rather than the diamond shaped apertures 4 that are present just in the metal sheet 6. This gentle curving of the plastics material avoids the formation of crevices which would then be available for the unwanted retention of bacteria. The flooring material illustrated in Figure 2 can easily be washed clean simply by hosing down.
Referring now to Figure 4, it will be seen thatthe metal sheet 6 has been ground on both its sides to remove the pointed ends 12, 14 at the points 10 of intersection of the metal strands 8. This grinding produces flat areas 18 which have less tendency than the pointed ends 12, 14 to wear through the coating of the plastics material 16. Furthermore, the flat areas 18 may be slightly softer for animals to walk on.
Advantageously, after the formation of the flat areas 18, the metal sheet 6 is degreased and then roughened over its surface by wheelabrating in order to enable the plastics coating 16 to more perfectly bond to the metal sheet 6.
The flooring material 2 is formed by priming the ground, degreased and wheelabrated metal sheet 6.
The metal sheet 6 is then pre-heated between two large sheets of heavy steel. These large sheets of heavy steel enable the pre-heating to be accomplished very quickly. Thus, for example, the preheating between the large sheets of heavy metal may be at 6000 Fahrenheit for 2 - 5 minutes.
The primed metal sheet 6 is then dipped in a horizontal position in a polyvinyl chloride plastisol contained in a tank. The coating of the metal sheet 6 with the plastisol may take 1.25 minutes with the plastisol in the tank being at a temperature of 105 Fahrenheit.
The plastisol coated metal sheet 6 is then removed from the tank containing the plastisol and the metal sheet 6 is rotated from the horizontal position 80" towards the vertical in both the clockwise and the anti-clockwise directions, the total rotational move ment of the metal sheet 6 thus being 1600. This rotational movement of the metal sheet 6 causes the drips of plastisol to run around the metal strands 8.
The drips thus level out to leave a smooth, heavy coating on the underside of the metal sheet 6.
The coated metal sheet 6 is then rotated to a vertical position and it is placed in a tank containing a heated salt solution. The plastisol on the metal sheet 6 cures in the heated salt solution. By way of example, it is mentioned that the curing may be effected in 3.75 minutes at a temperature of 425" Fahrenheit. This is a relatively quick curing time and it is due to the salt solution being a better conductor of heat than air. if desired, however, curing in a hot air stream can be employed or the coated metal sheet can be cured in an oven which is heated to a temperature of, for example, 360 to 4000 Fahrenheit.
After the curing, the plastics coated metal sheet 6 is cooled. This cooling may be effected in air or with water.
If it is necessary to cut the metal sheet after the plastics coating has been applied, then the exposed cut ends of the metal sheet are patched, usually with the same plastics material.
Referring now to Figure 5, the flooring material 2 illustrated in Figures 2 and 3 is shown positioned on a solid concrete floor 20.
In Figure 6, the flooring material 2 illustrated in Figures 2 and 3 is shown positioned on wooden joists 22. Preferably, the flooring material is laid on the joists 22 in the direction of the arrow 24 shown in Figure 2 for giving maximum strength and rigidity.
In the breeding of pigs, the flooring material 2 has been found to reduce deaths when compared with metal, wood and concrete floors. The flooring material has tended to improve overall animal health by reducing stress in the animals, the flooring material being quieter and drier than metal floors.
The known slippery metal, concrete or wood floors have resulted in young pigs slipping and spraining themselves and sometimes being unable to avoid being smothered by their mother. The flooring material of the present invention prevents this and it also prevents abrasions which often occur to the knees and hoofs of pigs, the abrasions often turning infectious.
The waffled mesh design illustrated in the drawings of the flooring material 2 tends to trap air and have an insulating effect, thereby minimising mastitis problems caused by udders on cold floors.
Generally, the use of the flooring material 2 tends to improve disease resistance and animal disposition.
It is to be appreciated that the embodiments of the invention described above with reference to the accompanying drawings have been given by way of example only and that modifications may be effected. Thus, for example, an apertured flat metal sheet could be employed instead of the expanded metal sheet 6 illustrated in Figures 1 and 4. Depending on the precise amount of plastics material bonded to the metal sheet 6, the apertures 4 in the finished flooring material 2 may vary from the shape illustrated in Figure 2. Further, a hot air oven may be used to pre-heat the metal sheet 6 and the various temperatures and heating and curing times given above can be varied.
