Abstract: The invention relates to a frame part (14) of a house construction for poultry, wherein the frame part (14) is provided with at least one hook member (15) for engaging on a contra-frame part (17). The invention also comprises a contra-frame part (17) which is provided with an edge part (16) for engagement of the hook member. The invention also comprises a house construction manufactured using such parts. The invention also comprises a profile part (5) for supporting laying nests (2) in a house construction, comprising a supporting surface and a groove-like edge (9) for supporting the slats (11).

Description: The invention relates to a poultry house construction comprising at least one frame part and one contra-frame part adapted for co-acting with the frame part. House constructions for poultry are understood to mean inter alia: frames for supporting laying nests, battery systems, systems for group accommodation, etc. Such constructions are usually manufactured, in particular welded, in components by a manufacturing company, which components are then transported to a poultry farm where they are assembled for instance by means of bolting or riveting, pop riveting or screwing. US-A-3.315.995 discloses a construction in which a C-shaped beam is connected to a column by welding a bracket to the column such that the bracket forms a beam seat to engage the inner surfaces of the upper portion of the C-shaped beam. The upper part of the beam forms a hook member engaging in a recess in the bracket (contra-frame part). This known construction still requires weldment of different parts, which is time-consuming. Moreover, when the C-shaped beam is connected to the bracket, the beam can still be moved longitudinally. Also the construction lacks stability in the longitudinal sense, i.e. in the direction of the C-shaped beam. US-A-3.124.102, on which the preamble of claim 1 is based, discloses a support structure for laying nests, in which a plurality of support stands, on which nest housings are mounted, are mounted to vertical standards. The different frame parts are connected by weldment to other elements. The assembly of this known support construction will require a considerable time. The present invention has for its object to provide improved components with which a poultry house construction can be manufactured in a relative, simple and fast manner. The poultry house construction is of a quality at least comparable to that of the existing house constructions for poultry and can be manufactured with a comparatively limited number of frame parts, wherein additional strength in the elements are not necessary, or less so, and wherein stability of the construction can be improved. It is also an object of the invention to provide improved components (frame parts and contra-frame parts) which can be interconnected without any additional connecting means like bolting, riveting, pop riveting, screwing, welding, bending, etc. and which can be disassembled in a fast and efficient way, whenever needed. According to the invention the object is achieved by the invention wherein the poultry house construction is characterized in that the frame part is provided with at least one hook member for engaging on the contra-frame part, the frame part is provided at a distance from the hook member with at least one supporting edge for supporting against the contra-frame part adapted for co-action with the hook member and wherein the contra-frame part is provided with an edge part for co-action with the hook member and a supporting surface located at a distance from the edge part for co-action with the supporting edge. Using such a (contra-frame part) frame part, one or more (frame parts) contra-frame parts for instance can be mutually coupled until the resulting construction has the required stiffness. In a preferred embodiment the contra-frame part is a post and these posts are mutually coupled using frame parts according to the invention. Using these frame parts and contra-frame parts a house construction can be assembled in very simple manner without special tools being required for the purpose. Assembly can take place in an exceptionally short time. Fewer components are also required, whereby the risk of erroneous assembly or waiting time to replace possibly missing components will occur less. The logistics of transporting a house construction to a poultry farm are also simplified. Assembly of the individual frame parts into larger components at the manufacturing location by welding these frame parts into sub-assemblies would be a less likely choice. The components for transporting can hereby be of smaller construction when use is made of frame parts and contra-frame parts according to the invention. The house construction can be assembled immediately from these smaller frame parts at the poultry farm. With this method the total labour time required for assembly of the house construction from the separate components will also be reduced. Yet another advantage is chat a house construction assembled from frame parts and contra-frame parts according to the invention is simple to disassemble. Finally, it is also possible to utilize the modular structure of such a house construction when for instance a part of the house construction is damaged or when a part of the house construction has to be modernized. Another preferred embodiment of the frame part comprises hook members for clamping a contra-frame part therebetween, wherein the hookmembers are directed in substantially the same direction. A possible embodiment thereof comprises at least two hook members located in the same plane for engaging a plate-like contra-frame part. Using these embodiments with hook members it is possible to fix a frame part to a contra-frame part without an opening having to be present in the contra-frame part for this purpose or there being an upper edge onto which the frame part can engage. Plate-like objects for instance, such as cover plates, planks etc., can thus be coupled to a frame part in simple manner. Structural elements of for instance laying nests can thus form part of the frame, whereby the functionality of the frame is enhanced considerably. This results in a considerably simpler construction of a frame with laying nests, as the two can be integrated. The present invention provides a house construction for poultry which incorporates at least one frame part and one contra-frame part according to the invention. It will be apparent here that a significant proportion of the above stated advantages can also be realized when some of the frame parts of a house construction are fixed rigidly to each other by for instance welding, riveting etc., and other frame and contra-frame parts are hooked to each other. Depending on the situation an optimum can be chosen for this purpose. The present invention moreover provides a profile part for supporting laying nests in a house construction for poultry, which profile part is provided with: a longitudinally running external surface for supporting at least one laying nest, and a groove-like longitudinally running edge located at a distance from the supporting surface for co-action with a coupling edge of slats. In a preferred embodiment such a profile part can also be provided with a protruding hook member for engaging on a contra-frame part. Finally, the invention provides a house construction which incorporates such a profile part. The profile part combines two functions which heretofore were fulfilled by separate profile parts. The number of construction elements in a house construction for supporting laying nests can hereby be reduced, which has a cost-saving effect. The present invention will be further elucidated with reference to the non-limitative embodiments shown in the following figures. Herein: figure 1 shows a cut-away perspective view of a house construction for supporting laying nests in which profile parts according to the invention are incorporated, figure 2 shows a cut-away perspective view of the profile part as incorporated in the construction shown in figure 1, figure 3 is a perspective view of a coupling of two frame parts to a contra-frame part according to the invention, figure 4 shows a perspective view of a partly cut-away commune system which incorporates frame parts and contra-frame parts according to the invention, and figure 5 is a perspective view of a part of a frame part according to the invention as incorporated in the commune system shown in figure 4. Figure 1 shows a house construction 1 for supporting laying nests 2. These laying nests 2 are constructed such that chickens preferably lay their eggs in laying nests 2, whereafter the laid eggs roll via a sloping floor surface 3 to a conveyor belt 4. This conveyor belt 4 subsequently carries the eggs away for further processing. Laying nests 2 are placed some distance above the floor surface of the house. The house construction 1 supporting laying nests 2 comprises two parallel running profile parts 5. These latter are supported by posts 6 and mutually connected using girders 7. The profile parts 5 according to the invention are formed such that they comprise a supporting surface 8 and a groove-like edge 9 running parallel to this supporting surface 8. Laying nests 2 can be placed on the supporting surface 8 of profile parts 5. A coupling edge 10 of slats 11 can be hooked into the groove-like edge 9. As this figure shows, slats 11 then connect onto laying nests 2 whereby the poultry has easy access to laying nests 2. Slats 11 are formed such that they let through the poultry manure. Figure 2 shows the profile part 5 in more detail. It can be seen here that girder 7 is provided with a hook-like element 12 which engages in a recess 13 arranged for this purpose in profile part 5. Also clearly shown are the supporting surfaces 8 and groove-like edge 9. Figure 3 shows two lying frame parts 14 which both comprise a hook member 15 with which the frame parts 14 engage on an upper edge 16 of a contra-frame part 17. Fixing of frame parts 14 and contra-frame part 17 is very simple. The frame parts 14 have only to be hooked on the contra-frame part 17. At a distance from hook members 15 the frame parts 14 are both provided with a support edge 18 with which the frame parts support against contra-frame part 17. This provides the connection of frame parts 14 and contra-frame part 17 the required stability. Figure 4 shows a commune system 19 in which a laying nest 2 is arranged. Also situated in commune system 19 are slats 11. This figure does not show that in the interior space of commune system 19 is situated a surface on which the poultry can forage. A commune system 19 combines the advantages of battery accommodation in respect of environmental and health aspects with the advantages of ground accommodation in respect of the welfare of the poultry. The poultry is accommodated in units 20, a part of which is formed by the slats 11 and a foraging part is also present. For instance 40 chickens and 4 roosters can be accommodated per unit 20. Side walls 21 of units 20 are mutually connected using a plurality of profile parts 22-29. These latter can herein also fulfil one or more other functions. Profile part 24 also forms for instance a support for slats 11. Profile parts 22-29 are provided on the end surfaces with protruding hook members 30 which co-act with recesses arranged for this purpose in side wall 21. Profile parts 22-29 can thus be coupled to side wall 21 in very simple manner. Finally, figure 5 shows in detail the profile part 24 as included in the commune system 19 shown in figure 4. The protruding hook members 30 are fixed on the end side surface of profile part 24.
