    DETAILED DESCRIPTION The principles of the present technology will now be explained with reference to exemplary embodiments thereof, which are shown in the accompanying drawings 1-7. The basic embodiment shown in the drawings is an example of an application of the principles of the current technology to a common, unspecified slab 10 15 20 25 30 4 of preferably concrete and intended to form a foundation or a foundation in a building. . It should be emphasized, however, that the embodiment shown is for the sole purpose of illustrating a presently preferred embodiment of this technology and is not intended to limit the technology to the details shown in the drawings. It should also be emphasized that the technology is not limited only to the construction industry or to concrete as a material in the construction, but with corresponding advantages can be applied to other areas to form solid foundations or for constructions consisting of other materials with similar material properties. However, such applications may require adaptation to the use and / or material properties of the structures in question.
    As mentioned, no solutions have emerged in the general field of technology that have been able to eliminate the problems initially discussed with regard to building structures.
    The new technology aims to find an efficient and safe solution to these problems and not least to the problems of achieving a building structure that has a significantly shorter delivery time than today's site-built structures and which still has a comparable strength.
    These objectives are achieved with the new technology through a completely new way of thinking, which basically involves forming a building structure by stably assembling a number of prefabricated, transportable building elements.
    This technology will be explained in more detail below with reference to an exemplary, partially schematic embodiment of a building structure. Figs. 1-7 show an embodiment of a building structure configured according to the now proposed technology and Fig. 1 shows in particular a very schematic view of an exemplary building structure 20 in an embodiment adapted especially for use in forming any type of purposeful foundation, foundation or equivalent in the construction industry. The building construction shown here is specially intended to be prefabricated by concrete casting.
    According to the technology described here, the building structure 20 comprises a number of adjacent building elements 1, 2 and joined at a joint 8 and a number of clamping elements 18 which impose a cohesive force F1 against the respective, adjacent building elements. In the embodiment, two adjacent and joined building elements 1, 2 are shown, but it should be obvious that the number of building elements used can be adapted to the surface of the foundation or foundation to be formed. The building structure 20 is thus formed by a first building element 1 which at at least a portion 3 of its outer circumference O1 has a first engaging formation 4 formed with alternating peaks 4A and valleys 4B and a second building element 2 which at at least one portion 7 of its outer circumference 02 likewise has a second engaging formation 9 which is correspondingly formed with alternating peaks 9A and valleys 9B. It is essential that the first and second building elements 1, 2 and the first and second engagement formations 4 and 4, respectively. 9 are made with mutually, mating complementary shapes to form a joint 8 with expedient strength in the manner described below.
    Referring to Fig. 1 and in particular to Figs. 2 and 5, the peaks 4A, 9A and valleys 4B, 9B of the engaging formations 4, 9 have in this building structure 20 a height A which is important for the strength of the joined building structure 20 and also for the compressive forces arises in the building elements 1, 2 when contracting them against each other. Expressed in another way are outer 12, 14 resp. inner 13, 15 end faces of the first and second engagement formations 4 and 4, respectively. 9 alternating peaks 4A, 9A and valleys 4B, 9B arranged at a mutual distance A. The significance of the magnitude of this distance A will be discussed below with reference specifically to Figs. 7 and 8. In a practical example, however, this distance is generally said to be between about 5 and 80% of the length LE for resp. building elements in the direction across the joint 8, preferably between about 20 and 50% of this length. Dimension A, on the other hand, is normally chosen no larger than the joint 8 becomes iron-strong with the building elements 1, 2 themselves.
    Furthermore, the first and second engagement formations 4 of the building structure 20, respectively. 9 in the embodiment shown, peaks 4A, 9A and valleys 4B, 9B which have outwardly generally converging resp. diverging side surfaces 5, 10. As an alternative, it is also conceivable to make these peaks resp. valleys with basically straight side surfaces, to some extent to facilitate the joining of these, or even to make the tops resp. the valleys with curved resp. corrugated profiles (not shown).
    In the basic embodiment with joined building elements 1, 2 of concrete, a number of clamping elements 18 are used in the building structure 20, each of which preferably consists of an at least partially threaded drawbar 18. The drawbars 18 are freely received through aligned 19 holes in adjacent building elements 1. 2. Nuts 18A are preferably used to clamp the separate, adjacent building elements 1, 2 against each other with the aid of a pulling force F1 by means of the drawbars 18. The number of tie rods 18 used for the clamping may vary depending on the circumstances of the specific application but are preferably selected equal to or less than the number of peaks 4A, 9A and valleys 4B, 9B in the engaging formations 4, 9 of the building elements 1, 2.
    As shown in the diagrams, and most clearly in Fig. 6, each of the separate, adjacent building elements 1, 2 of the building structure 20 in connection with the joint 8 is provided with a number of in a general longitudinal direction LS for the joint 8 separated transverse force supports 16, 17. The transverse force supports 16, 17 are here made in the form of a groove 17 in the first and second building elements 1, 2 valleys 4B and 9B and in the form of a protruding spring 16 in the tops 4A and 2, respectively, of the first and second building elements 1, 2. 9A. The number of transverse force supports 16, 17 used in the building elements 1, 2 can also be varied depending on the circumstances of the specific application, but basically a pair of grooves is arranged for each top and valley combined in the joined condition in the engaging formations. In the embodiment shown, spring 16 and groove 17 are only arranged in the surfaces which are perpendicular to the bending moment MB (Fig. 7), but for specific applications with special circumstances it is also possible to arrange these also in other surfaces in the joint 8.
    In general, it can be seen that with increasing distance A, the compressive forces F 2 (see Fig. 7) in the material of the building elements decrease, ie. usually in the concrete. If measure A were to be doubled, e.g. the compressive forces to be reduced by half in the material / concrete. Concrete only absorbs compressive forces, while tensile forces are absorbed by the material, preferably steel, in the drawbars 18 or equivalent. With special reference to Figure 7, it appears that the joint, displaced or irregular joint 8 proposed according to the new technology in a divided building structure 20 provides considerable advantages in terms of the ability of a building structure formed by separate building elements 1, 2 to absorb bending moments. MB. It appears, among other things. that the material is in principle only exposed to pure compressive forces F2 which can be said to act in the opposite direction to the transverse force supports 16, 17 displaced by the A-measure. In the case of thin building structures 20, the thickness T loses in practice significance. For comparison, Fig. 8 schematically illustrates how a straight joint 108, i.e. with the measure A = O, would have the ability to transmit a bending moment MB ”. In this case, it is shown how the compressive load F2 "has an adverse effect on a building structure 120 at the straight joint 108. In such a case, the thickness T" of the building structure / concrete slab 120 would, on the other hand, be absolutely decisive for the ability to safely absorb the compressive forces.
    A joint 8 formed between adjacent building elements 1, 2 in a building structure 20 according to the new technology is thus characterized by a first engaging formation 4 with alternating peaks 4A and valleys 4B at a portion 3 of an outer circumference O1 of a first building element 1 and a second engaging formation 9 with alternating peaks 9A and valleys 9B at a portion 7 of an outer circumference 02 of a second building element 2. The first and second building elements' respective first and second engaging formations have mutually mating complementary shapes and in connection to the joint, each of adjacent building elements 1, 2 is preferably provided with a number of transverse force supports 16, 17 separated in a general longitudinal direction LS for the joint 8, which stabilize the joint 8 and absorb transverse forces between the building elements.
    Finally, the described technology also comprises a method for forming a building structure 20 as above, wherein a number of adjacent building elements 1, 2 are joined so that a joint 8 is formed between the building elements and a cohesive force F1 of clamping elements 18 is applied to the building elements joined to the joint. A first building element 1 is embodied / provided at at least a portion 3 of its outer circumference O1 with a first engaging formation 4 which is formed with alternating peaks 4A and valleys 4B. Furthermore, a second building element 2 is formed / provided at at least a portion 7 of its outer circumference 02 with a second engaging formation 9 which is likewise formed with alternating peaks 9A and valleys 9B. The first and second engaging formations of the first and second building elements are then formed with mutually, mating complementary shapes and the first and second engaging formations are brought together and clamped together by the clamping elements 18 to form the joint 8.
    The first and second engagement formations 4, 9 are each formed with outer 12, 14 and 14, respectively. inner end surfaces at their peaks 4A, 9A and valleys 4B, 9B arranged at a mutual distance A of between about 5 and 80%, preferably between about 20 and 50%, of the length LE for resp. building elements in the direction across the joint 8. These first resp. the peaks 4A, 9A and valleys 4B, 9B of other engaging formations 4, 9 are formed with straight or alternatively outwardly generally converging resp. diverging side surfaces 5 resp. 10.
    At least one partially threaded drawbar 18 is passed freely through holes 19 accommodated in adjacent building elements 1, 2 and clamped with traction force F1 to each of these building elements and in connection with the joint 8 a number of in a general longitudinal direction LS for the joint 8 separated transverse force supports 16, 17.
    These described basic embodiments entail advantages in the form of: a very stable and above all moment-rigid, composite building construction with a strength comparable to that of a one-piece concrete slab; - improved flexibility in the formation of building structures with Lex. different form; and - a cost-effective solution in terms of fabrication, transport and installation.
    Compared with current technology, which consists of site-built concrete slabs, more precisely a divisible concrete slab according to this new technology can be prefabricated and economically transported to and assembled very quickly on a construction site. The building structure according to this technology can also be dismantled and rebuilt elsewhere. It can also be easily designed as a split plate with cast-in drains, water pipes and underfloor heating, which is an important and large market. Delivery time from warehouse can probably be reduced to one week, which as mentioned is significantly shorter delivery time than for site-built concrete slabs. In addition, you can count on about an hour of assembly time, which together gives a very advantageous total time.
    Such a divisible concrete slab is also very moment-rigid and the strength can be kept comparable to that of a concrete slab which is cast in one piece. While an entire concrete slab is very expensive, if even possible, to transport, the moment-rigid, divisible concrete slab enables normal economical transport. Additional advantages are that the divisible concrete slab according to the new technology can be prefabricated, which gives a lower price and more even quality, and that it t.o.m. can be shipped together with a cottage kit or equivalent. In alternative, but not specifically shown embodiments of this technology, variants or modifications of different shown parts of the building construction formed by the building elements resp. of the joint between these building elements is utilized without deviating from its scope. Above all, the technology is not limited to the shown and described, schematic design where the complementary engaging formations have the shown general trapezoidal shape on its peaks and valleys. It also includes variants and modifications that provide the same basic functions as described above, but with different detailed embodiments of the engagement formations. The same applies to designs where building elements have engaging formations at more than a portion of their circumference, to form larger continuous structures. Although the technology is currently considered to have its main application in cast concrete structures, it can also be used for materials with similar material properties and for other purposes. Basic principles for the described technology can thus be applied to other types of building elements and, where applicable, to other types of applications than just foundations and foundations.
    The technology has been described in connection with what is now considered to be a most practical and preferred embodiment, but it should be understood that it is not limited to the embodiments shown and described. This technology must therefore cover various modifications and equivalent arrangements that fall within the basic concept and scope of protection of the appended claims.
