Grating element for a rg pet stall /

Priority: No. 481/75, January 16, 1975, Switzerland

The innovation concerns a grating element for one
• ey animal holding area, especially for animal holding areas with
one thereby formed within solid frame parts
Step surface that grating elements are placed on support profiles within the frame parts in the area of the step surface, so that the grating elements form an essentially continuous and even grating surface.

For the rearing of young animals, such as piglets, it was recognized that by keeping them on previously known mesh grids the risk of illness and therefore mortality can be significantly reduced, especially with sufficient distance

dea grid from the floor of the installation site of the relevant Holding status. This success is based on

that the excreted feces of the animals from the j

the animals clean and dry without any effort. j

In addition, there is no temperature gradient for the animal carcasses, which is especially true when keeping animals in air-conditioned Room has a beneficial effect.

The disadvantages of the previous animal holding stands are i

the adverse effect on the animal's claws in the previously known mesh grids, in the impaired Rest of the animals because of the uneven lying surface the previously used mesh grids, in the labor-intensive cleaning of the previously rigid training between Support surface and side wall grilles as well as the small Lifespan of the mesh grids used because of the aggressive faeces and urine. There was a task in remedying the identified disadvantages and for to ensure proper development of the claws and legs for high quality breeding animals. In addition, a simple, quick and easy cleaning ensured will. ;

This task was achieved through the combined use of profile support rods and Overlaid grating elements made of corrosion-resistant Plastic loosened. Due to the extremely good development of rearing animals in the described

Animal holding stands grew up with keepers and breeders of Large cattle the desire to create suitable stands. In particular, the familiar concept should be retained will. The main difficulties arose in the manufacture of suitable corrosion-resistant grating elements and out of this the task of the innovation, large load-bearing capacity with high specific surface loads at the same time, good and largely independent falling through of the animal droppings and easy handling for cleaning au guarantee. In addition, the step level of the grating elements should be Provide the animals with sufficient security of step, with the intended use high wear resistance and be difficult to damage by Ifager.

With injection molding, which was previously used conventionally were especially the high load-bearing capacity, the high specific surface loads and the surefootedness paired with largely automatic animal excrement cleaning, thanks to free diarrhea, is practically no longer feasible.

Attempts have already been made to cast and punched metal gratings with slotted openings, including slotted gratings called, to use, which have better corrosion resistance than known cast iron grates, especially Aluminum alloys. When using such metallic split grids for dams, especially pigs, happened

injuries to the teats are caused by the slit or split cantons. So other solutions had to be found.

One such is presented.

The innovation at the animal holding stand is characterized by the fact that the grating elements made of plastic are included in them embedded inserts to increase flexural strength are made.

To further improve the mutual relationships in the tasks, in particular the deposits consist of metallic profile rods in plastic, which are encased on all sides by foamed plastic.

The metallic profile bars, adapted to the design of the grating element, can be connected to one another and embedded in plastic.

in FIG. 3 a section along HI-III of the harvesting variant, ¹ "in FIG. 4 a second variant along IX-II in FIG. 1, in FIG. 5 a third variant of the structure of the grating bars in a sectional view on a larger scale, in FIG 6 two types of installation of animal holding stands with the grating elements inserted.

The animal holding stand 1 according to Fig. 6 has fixed frame parts 2 and 3? fixed or pivotable stine walls 4 and 5 as well as with a grating 6, which is arranged at a distance above the floor of the installation site and a step surface forms, provided. The fixed frame parts 2 and 4 preferably consist of two fastened to the ground Frame feet 12 and 13, one between these feet 12 and 13 extending support beam 14 and a frame rod 16 arranged on the upper boundary between these Frame parts 2 and 3 have a fixed end wall 4 installed. As an alternative to this version, a frame foot can be used a Tz * agplatte 23 connected to the frame rod 16 and fastened to the wall of the installation site as well as through any known type of fastening of the support beam 14 in the wall 7 of the installation site can be replaced. With the support bars 14 are connected to support elements for receiving profile support rods. On the. Profile support bars are Grating elements 6 inserted in such a way that between the frame parts 2 over the grating elements 6 a continuous Entrance level for those educated in this way

Tierhalteatand 1 animals to be kept is formed, Bine the end walls 5 are pivotably attached to the frame part 2.

Each grating element 6 comprises, as essential parts, a plurality of grating bars extending between frame end profiles 86 81. To generate great load-bearing capacity and rigidity, in the transverse direction to the longitudinal extension of the bars are such Grating elements 6 are provided with transversely extending intermediate profiles 87 lying between them. The openings 82 point between the bars 81 away from the tread 88

increasing cross-sectional areas towards the bottom. To when several grating elements 6 collide with the Butt parts 89, 89 'also have faecal diarrhea openings 82 To create, the frame end profiles 86 can one or protrude on both sides over the outermost bars.

The grating elements 6 are a combination of, on the one hand, a plastic that gives the external shape, which is preferably according to the structural foam process, i.e. a one essentially pore-free outer skin and a hardened, porous, inelastic core-forming process, is processed and on the other hand embedded in the plastic 182, which serves to increase the flexural strength Deposits 181. Through this manufacturing principle, the fulfills the tasks and requirements specified in the introduction.

7541257 10/7/76

Depending on the required load-bearing capacity, the inserts 181, which are embedded in the plastic 182, can now be very different Have shape. A method that is already widely used is the incorporation of fibers of various types, especially made of glass or metals.

For the present application, a new one turned out to be Type of reinforcement as very suitable, although it does not save a considerable amount of weight, but very high rigidity in all of them Directions is achieved.

A framework adapted to the structure of the grating element 6 ′ is prefabricated from metallic profiles, then placed in the mold that forms the plastic and then poured into it Plastic, preferably according to the structural foam process, enveloped.

Figures 2 and 3 show the essentials of such grating elements 6 from the combination of metal prefabricated framework 181 and 18 6, embedded in plastic body 182. As a metallic one Frameworks for the bars are tubes 181 used, which with further tubes 136 as a framework for the frame end profiles 86, if necessary also the intermediate profiles 87, connected, preferably be welded.

Another possibility of metallic reinforcements for the bars is shown in Figure 4, according to the

7541257 10/7/76

Shaped sheet metal profiles 18 2 'are used according to requirements will. The main advantage lies in the easy customization of the Shape of this skeleton part in terms of shape or weight Requirements for the ready-foamed grating element. In the example shown, the weight is relatively low realized *

As an alternative to the tubes for the framework of the bars 81 according to FIG. 2, T-profiles 18 2 ″ according to FIG. 5 can also be used Find. Above all, these enable strong cross-sectional expansion on plastic 181 "above the height of the openings between the bars, which means" self-cleaning ", i.e. the unhindered fall through of the animal faeces.

The animal holding stand equipped with grating elements of the type described above according to the main patent 545 585 is characterized is characterized by the large load-bearing capacity of the entire tread area, by good surefootedness for all types of animal claws and hooves as well as body-friendly, i.e. non-cooling pad material, What is in addition to the advantages according to the main patent, its use for keeping, especially rearing of heavy animals such as calves and cattle.
