BUILDING STRUCTURE

Abstract: A building structure comprises interconnectable structural building elements (1, 2, 3), said structural building elements (1, 2, 3) comprising, for the interconnection, female and male edge portions (4, 5) for engagement with the adjacent structural building elements (1, 2, 3). The structural building elements (1, 2, 3) are formed by two rigid surface layers (6, 7) and a continuous insulating layer (8) located therebetween. The male edge portions (4) are formed by the substantially continuous insulating layer (8) and by the two rigid surface layers (6, 7), each of which comprises a step (9), on the surfaces (10, 11) turned away from the insulating layer (8) in the transition between the male edge portions (4) and the other portions of the structural building elements (1, 2, 3). The female edge portions (5) are formed by solely the two rigid surface layers (6, 7), which are so adapted that they lie closely adjacent to the steps (9) and that their surfaces (10, 11) turned away from the insulating layer (8) form flat surfaces in the transitions between adjacent structural building elements (1, 2, 3), said continuous insulating layer (8) in a structural building element (1, 2, 3) being directly adjacent to the continuous insulating layer (8) in an adjacent structural building element (1, 2, 3), so that a substantially continuous insulating layer (8) is formed in the building structure.

Description: Building structure. FIELD OF THE INVENTION AND PRIOR ART The present invention relates to a building structure comprising interconnectable structural building elements, said structural building elements comprising, for the interconnection, female and male edge portions for engage¬ ment with the adjacent structural building elements. Building structures of the aforementioned type are al¬ ready well known in the field of building structural engineering. However, these known building structures have a lot of disadvantages such as the creation of ther¬ mal bridges between the inner side and the outer side of the building structure, especially in corner and edge regions of the building structure, and the non-obtaining of flat and even surface layers of the building structure in the transitions between the structural building ele¬ ments. SUMMARY OF THE INVENTION The object of the present invention is to provide a buil¬ ding structure having a substantially continuous insula¬ ting layer formed between two rigid surface layers in order to avoid thermal bridges. Another object of the present invention is to provide a strong and resistant building structure having flat and even transitions between structural building elements. According to the present invention these objects are obtained by the fact that the structural building ele¬ ments are formed by two rigid surface layers and a conti¬ nuous insulating layer located therebetween, that the male edge portions are formed by the continuous insulating layers and by the two rigid surface layers, each of which comprise a step on the surfaces turned away from the insulating layer in the transition between the male edge portions and the other portions of the structural building elements, and that the female edge portions are formed solely by the two rigid surface layers, which are so adapted that they lie closely adjacent to the steps and that their surfaces turned away from the insulating layer form flat surfaces in the transitions between- adjacent structural building elements, said continuous insulating layer in a structural building element being directly adjacent to the continuous insulating layer in an adja¬ cent structural building element, so that a substantially continuous insulating layer is formed in the building structure. In this way, the present invention achieves the advan¬ tage that the building structure gets comparatively strong with even, flat transitions, between the structural buil¬ ding elements and get a substantially continuous insula¬ ting layer which is the only thing that interconnect the rigid surface layers. Further objects and advantages will appear from the appen¬ ded dependent claims. BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described by means of an example of- an embodiment with reference made to the enclosed drawings, on which: Fig 1 is a partial perspective view of a corner of the building structure according to the invention in a not assembled state. Fig 2 is a view similar to the one in Fig 1 , but in an assembled state. Fig 3 is a perspective view of the corner structural building element shown in Fig 1 and 2. Fig 4 is a perspective view of one of the three edge structural elements in Fig 1 and 2 cut-off transversally to its longitudinal direction. Fig 5 is a view of a second embodiment of the building structure according to the invention from the opposite direction with respect to the view in Fig 1. DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION In the figures 1-4 a preferred embodiment of the building structure according to the invention is shown. The buil¬ ding structure comprises structural building elements 1, 2 , 3 being interconnectable by means of female and male edge portions 4, 5 on the structural building ele¬ ments 1, 2, 3 in question. The structural building elements 1, 2, 3 are formed by two rigid surface layers 6, 7 and a continuous insula¬ ting layer 8 located therebetween. The male edge portions 4 of the structural building ele¬ ments 1, 2, 3 are formed by the continuous insulating layer 8, ' which has a smaller thickness in the male edge portion 4 than in the other portions of the structural building elements, and by the two rigid surface layers 6, 7, each of which form a step 9 in the transition bet¬ ween the male edge portions 4 and the other portions of the structural building elements 1, 2, 3. The female edge portions 5 are formed by solely the two rigid surface layers 6, 7, which are so adapted that they lie closely adjacent to the steps 9 and that their » surfaces 10, 11 turned away from the insulating layer 8, i.e. the visible internal and external surfaces of the structural building elements 1, 2, 3, form flat sur¬ faces in the transitions between the adjacent structural building elements 1, 2, 3. The steps 9 in the surface layers 6, 7 may be formed in different ways. They may be, formed either in a surface layer 6, 7 itself or by arranging the surface layers 6, 7 comprised in the male edge portions 4 inside the surface layer 6, 7 of, the structural building elements 1, 2, 3 and overlapped thereby. In the embodiment shown a further step 12 is formed. This step 12 is established on the surfaces 13, 14 turned towards the insulating layer 8 in the transition between adjacent structural building elements 1, 2, 3, when the structural building elements 1, 2, 3 are interconnected. However, this step 12 may be removed, so that the surfaces 13, 14 facing the insulating layer 8 get just as even and flat in the transition between the adjacent structural building elements 1, 2, 3 as the surfaces 10, 11. The insulating layer 8 is then getting the same thickness in the transition between the adjacent elements 1, 2, 3 as in the other portions of the elements 1, 2, 3. The removal of the step 12 may be achieved by the fact that the rigid surface layers 6, 7 of the female and -male edge portions 4, 5 have a total thickness corresponding to one surface layer 6, 7 beside the edge portions. In fig 1 three different types of structural building elements 1, 2, 3 are shown, namely a first type of flat structural building elements 1 , a second type of struc¬ tural building elements 2 forming a portion of an envelop surface of a tube and a third type of structural buil¬ ding elements forming a portion of a hollow sphere. The third type of structural bulding elements 3 (see fig 3) comprises three male edge portions 4 for receiving three structural building elements 2 of the second type. The structural building element 3 of the third type is in the preferred embodiment so adapted that the three structural building elements of the second type are orien¬ tated perpendicularly to each other. In the preferred embodiment the structural building element 3 of the third type receives also three structural building elements 1 of the first type in the corners 15 between the male edge portions 4. The second type of structural building element 2 compri¬ ses in the preferred embodiment two opposed female edge portions 5 each intended to receive the male edge portion 4 of a respective structural building element 3 of the third type and two male edge portions arranged perpen¬ dicularly to each other and each intended to receive a female edge portion 5 of a respective structural buil¬ ding element 1 of the first type. The structural building elements 2 of the second type are symmetrical with res¬ pect to on one hand a line extending from a female edge portion 5 to the one opposite thereto and on the other with respect to a line extending from a male edge por¬ tion 4 to the one opposite thereto. The structural building element 1 of the first type has four female edge portions 5 intended to receive four structural building elements 2 of the second type as well as four structural building elements of the third type in the corners between the edge portions 5. The edge portions 4 and 5 are delimited of inner and outer edges 16, 17, respectively, and the insulating layer 8 is terminated in a section either at the inner or at the outer edges 16, 17, said insulating layer being rectangular in the structural building elements of the first and second types. The inner edge 16 along an edge portion 4, 5 of a struc¬ tural building element 1, 2, 3 is closely adjacent to the outer edge 17 of an edge portion 4, 5 of an adjacent structural building element 1, 2 , 3, the inner and outer edges 16, 17 having the same length, while the outer edge 17 along the edge portion 4, 5 mentioned first of the structural building element 1 , 2, 3 lies closely adjacent to the inner edge 16 of the latter edge portion 4, 5, said outer edge 17 of the edge portion mentioned first and the inner edge 16 of the latter edge portion 4, 5 also having the same length. The inner and outer edges 16, 17 of a structural building element 1, 2, 3 are parallel to each other. Fig 5 illustrates another embodiment of the invention. This embodiment shall exemplify the possibility to have other combinations between the female-male edge portions 4, 5, see for example the structural building element of the second type which here has only male edge portions 4. A disadvantage of this embodiment consists of the fact that the labyrint effect achieved in the embodiment according to fig 1-4, i.e. there are no joint extending straight through the building structure, is not obtained, see for example the arrows P. Thus, the invention is of course not to be considered as restricted to an embo¬ diment with the female-male edge portions 4, 5 arranged as it appears from the embodiment shown. Furthermore, it is evident that the invention with res¬ pect to other details are not restricted to the embo¬ diment shown above, but the invention may be modified in a plurality of ways without diverting from the idea of the invention. For example, the angles of the struc¬ ture elements 2, 3 may be other than right angles. Furthe more, the insulating layer 8 may protrude more than the rigid surface layer 6, 7 in order to further increase the labyrint effect. In the practice the insulating layer 8 may be produced from cellular plastic, while the sur¬ face layers 6, 7 are produced from more rigid plastic. The insulating layer and the surface layers may be separa tely free-manufactured and assembled by gluing. Alter¬ natively, the insulating layers may be formed by extru¬ ding foamed plastic between pre-manufactured surface layers, held in a mould or the like. In the assmebling of the structural building elements cementing of the rigid layers of the female and male edge portions and also of the surfaces of the insulating layers bearing against each other are preferably carried out. After the assemblage covering material, putty or the like is applied in the joints at the steps 9, so that comple¬ tely even outer and inner surfaces are obtained, where¬ upon possibly painting or other surface treatment may take place.
