    I EDGE ELEMENTS FOR A BUILDING LAND AND BUILDING LAND INCLUDING SUCH EDGE ELEMENTS FIELD OF THE INVENTION The invention relates to an edge element for a building site. More specifically, the present invention relates to an edge element which is suitable for building foundations of the slab type on the ground. Such building foundations are arranged directly on a suitable surface without underlying space and comprise a frame of edge elements, an insulating layer arranged in the frame of edge elements, such as a foam plastic layer, and a concrete slab arranged and reinforced on the insulating layer. Such building foundations are often used for commercial buildings, industrial buildings and houses, such as residential buildings, villas, holiday homes and the like. Edge elements of the type intended are placed in the periphery of the building site to form a mold when casting the concrete slab and to form a load-bearing edge beam of the building site. The invention also relates to a building foundation comprising edge elements.
    PRIOR ART There are different types of edge elements for building foundations of the slab type on land in prior art. Such a type of edge element is a challenge in the form of a beam of load-bearing and insulating material, such as reinforced cement-bonded slatted clinker. & Marla edge elements are made with a substantially rectangular cross-section and with a recess in an upper horn of an inner side of the edge element, in which recess anchoring means are arranged for co-operation with a reinforcing mesh of the building foundation. An outer side of the edge element may be provided with a layer of slatted concrete or other material to achieve an advantageous appearance of the building foundation.
    A problem with such edge elements for building foundations of prior art is that they result in a building foundation with a relatively low insulating shape, which can result in relatively high operating costs for heating or cooling a building comprising the building foundation. There is thus a need for improved insulation capacity of building foundations with such edge elements.
    SUMMARY OF THE INVENTION An object of the invention is to avoid the above-mentioned problem with prior art and to meet the need for improved insulation design. The edge element according to the invention enables a considerable improvement of the heat-insulating body of a building foundation at the same time as the edge element is load-bearing and can carry considerable loads, such as a brick cradle or the like, also on an outer part of the edge element. The edge element according to the invention also maintains a good, stable and durable interaction between a concrete slab of the building foundation and an inner side of the edge element. In addition, a robust and durable edge element is provided that is not easily damaged during handling, such as during transport, loading, unloading and placement on a construction site.
    The present invention relates to an edge element for a building foundation, such as a building foundation of the slab type on the ground, comprising an inner first portion, an outer second portion and an insulating layer arranged between the first portion and the second portion, the first portion and the second portion comprising a first material and the insulating layer comprises a second material, the second material having a higher insulating capacity than the first material, the insulating layer being formed with a plurality of slidings extending transversely through the insulating layer, and the first portion being connected to the second portion via the Mien. stretching connecting portions. By arranging the insulating layer, which insulating layer may be the only insulating layer of the edge element, between the first portion and the second portion a good insulating shape of the edge element is provided while the insulating layer is protected during transport and handling of the edge element, so that damage to the insulating layer avoided. The connecting portions of the edge element are load-bearing and result in a good connection between the first portion and the second portion, so that extensive loads can also be supported by the outer second portion of the edge element. In this way, 3 good insulating properties are achieved, while the edge element is maintained while good load-bearing properties are maintained. The edge element according to the invention also results in good mechanical cooperation with a concrete slab having the building foundation, even without a wall in the form of a thicker edge portion of the concrete slab, so that a wall-free building foundation can be achieved. The inner first part has the edge element can directly cooperate with the concrete slab without intermediate material, so that the inner first part of the edge element is cast together with the concrete slab and gives a robust cooperation between them even without vout. Thus, through the design of the edge element, good cooperation between the inner first part and the concrete slab can be achieved at the same time as good and load transferring cooperation between the inner first part and the outer second part via the connecting parts is achieved, resulting in a robust building foundation that can carry significant loads. without the periphery.
    The bonding portions of the edge element can be distributed inside the edge element and along a longitudinal direction of the edge element at an appropriate distance from each other in order to achieve a good balance between the insulating properties of the edge element and the load-bearing properties of the edge element.
    The connecting portions can be made of reinforcement or can comprise or be challenged by the first material, ie. the same material as the first batch and the second batch, whereby the connecting batches can be integrated with the first batch and the second batch. For example, the first material comprises mineral material in the form of stone material. For example, the first material includes rock material, such as aggregate, and binder, such as cement or other suitable binder. For example, the first material comprises concrete. For example, the first material includes slatted clinker, such as reinforced cement-based slatted clinker or slatted concrete. In this way, a choice of insulating and load-bearing edge elements is achieved which is relatively easy to prefabricate and transport to the intended location.
    The invention also relates to a building foundation, such as a building foundation of the slab type on the ground, comprising edge elements as above, basic insulation, reinforcement, such as reinforcing mesh or the like, and a cast concrete slab. The building foundation according to the invention has good insulating properties and good load-bearing properties. According to one embodiment, for example, the building foundation, in its peripheral part, can support asterisks, such as a brick wall or similar load. The concrete slab can be cast together with the inner first part of the edge element.
    Further features and advantages of the present invention will become apparent from the description of exemplary embodiments below, the accompanying figures, and the dependent claims.

The building foundation 10 is of the flat type on the ground and is, for example, challenged to be applied directly to a substrate, such as a substrate comprising rock crusher, macadam ether similar to a suitable building material for a building foundation. The building foundation 10 comprises a plurality of edge elements 11, base insulation 12, reinforcement, such as reinforcement mesh 13, and a concrete slab 14, the concrete slab 14 being cast on the base insulation 12 and the reinforcement joints 13, for example, to thank the base insulation 12 and incorporate the reinforcement joints 13 in the concrete slab 14. 6 The edge elements 11 are challenged to form a mold for casting the concrete slab 14 and to form a load-bearing edge beam of the building foundation 10. The edge elements 11 are for instance designed to form a frame, such as a load-bearing frame, for the concrete slab 14 and to form a peripheral limitation of the building foundation 10. In the embodiment shown, the edge elements 14 comprise anchoring means 15 for co-operation with the reinforcing mesh 13, for example via conventional and not shown anchoring brackets, in order to achieve a good co-operation between the concrete slab 14 and the edge elements 11. in steel in the conventional way.
    The edge elements 11 are, for example, cast together with the concrete slab 14.
    Referring also to Fig. 2 and Fig. 3, an edge element 11 according to an embodiment of the invention is shown. The edge element 11 is elongate and comprises a short side 16, an inner side 17, an upper side 18 and an outer side 19. One short side 16, the upper side 18 and the inner side 17 are shown in Fig. 2, the other short side 16 , the upper side 18 and the outer side 19 are shown in Fig. 3. The edge element 11 further comprises a lower side opposite the upper side 18, which lower side is not shown in the figures and is, for example, arranged for abutment against the ground. The inner side 17 comprises the anchoring means 15 and is designed to be directed towards the concrete slab 14, the outer side 19 being challenged to be directed in the opposite direction and form a visible part of the building foundation 10 of a prefabricated building. The inner side 17 is, for example, a challenge for abutment against or concreting with the concrete slab 14. The upper side 18, for example, is designed to abut against external walls or the like of the building. For example, the short sides 16 are made with the corresponding design of the innards. The edge element 11 is elongate and is formed with a length, i.e. a distance between the short sides 16, for example 1-10 m, 2-8 m or 4-6 m, or another optional length. For example, the edge element 11 is made with a length of 6 m. For example, the edge element 11 is made with a thickness, ie. a distance between the inner side 17 and the outer side 19, p8 100-600 mm, 200-400 mm or for example 250 or 300 mm. For example, the edge element 11 is made with a shank, ie. a distance between the upper side 18 and the lower side, of 200-600 mm, 300-500 mm or 400 mm. The edge element 11 comprises an inner first portion 20, an outer second path 21 and an insulating layer 22 arranged between the first portion 20 and the second portion 21. The first portion 20, the second portion 21 and the insulating layer 22 are for instance arranged parallel to each other and in level 6 with each other. For example, the first portion 20, the second portion 21 and the insulating layer 22 are challenged at the same height and stack between the lower side of the edge element 11 and the upper side 18. In the embodiment shown, a free side of the inner side of the first portion 20 forms the inner side 11. 17, an opposite side of the first portion 20 abutting the insulating layer 22. For example, the free side of the first portion 20 is challenged to abut or abut with the concrete slab 14 so that the free side of the first portion 20 directly cooperates. with the concrete slab 14 without intermediate material. In the embodiment shown, the insulating layer 22 is arranged centrally in the edge element 11, a thickness of the first portion 20 substantially corresponding to a thickness of the second portion 21. For example, the insulating layer 22 is connected to the first portion 20 and the second portion 21 in the abutment surfaces in between.
    The first portion 20 and the second portion 21 comprise or are challenged in a load-bearing first material. The first material includes, for example, slatted clinker, foam reinforced cement-bound slatted clinker and / or reinforced slatted clinker concrete. For example, the first portion 20 and the second portion 21 are challenged in reinforced cement-bonded slatted clinker and / or reinforced slatted clinker concrete with a density of 700-1700 kg / m3 or 900-1200 kg / m3. Alternatively, the first material comprises optional ballast and a binder, skarn cement or other suitable binder. For example, the first material comprises mineral material, shoes in the form of stone material. For example, the first material comprises concrete. The insulating layer 22 is made of a second material with a higher insulating ability than the first material of the first portion 20 and the second portion 21. For example, the insulating layer 22 is made of a material with a higher insulating ability than cement-bonded slatted clinker and slatted concrete. The insulating layer 22 is, for example, made of expanded plastic material or the corresponding high-insulating material. For example, the insulating layer 22 is made of polyurethane (PUR). Alternatively, the insulating layer 22 is made of cellular plastic, such as expanded polystyrene. In the embodiment shown, the insulating layer 22 is made in the form of a sheet of highly insulating material.
    The first portion 20 comprises the inner side 17 of the edge element 11 and is for instance designed to abut against the basic insulation 12 and cooperate with the reinforcing mesh 13 via the anchoring means 15. The first portion 20 is designed to form an inner load-bearing part of the edge element 11, wherein the second portion 21 is formed to form an outer load-bearing part of the edge element 11. For example, the edge element 11 comprises only a layer of highly insulating material, i.e. the insulating layer 22, and no additional high-insulating insulating layers. For example, the outer side 19 of the edge element 11 is free of highly insulating material.
    Referring to Figs. 4-6, the edge element 11 according to an embodiment of the invention is shown. The edge element 11 comprises connecting portions 23, which connect the first portion 20 to the second portion 21 to enable the transfer of loads therebetween. Fig. 4 shows a part of the outer side 19 of the edge element 11, the connecting portions 23 being shown by means of dashed lines. Fig. 6 shows the stretching of a connecting portion 23 through the insulating layer 22 between the first portion 20 and the second portion 21. The connecting portions 23 are distributed along a longitudinal direction of the edge element 11, the connecting portions 23 being arranged at a distance from each other in the edge element 11. long distance. For example, the connecting portions 23 are arranged at a spacing of 50-500 mm or 100-300 mm. Thus, between the connecting portions 23, the insulating layer 22 is intact and extends continuously in the height direction of the edge element 11, as shown in Fig. 5.
    In the embodiment shown, parts of the insulating layer 22 are arranged between the connecting portions 23 and the upper side 18 of the edge element 11 and between the connecting portions 23 and the lower side of the edge element. For example, the connecting portions 23 are arranged substantially centrally in height in the edge element 11, the connecting portions 23 being completely enclosed in the edge element 11.
    Alternatively, the connecting portions 23 are offset towards a lower side of the edge element 11, as shown in Fig. 4 and Fig. 6, so that the connecting portions 23 are arranged with a larger distance to the upper side 18 of the edge element 11 from the the lower side has the edge element 11. The connecting portions 23 are made with a height which is substantially less than a height of the edge element 11. For example, the connecting portions 23 are challenged with a height which corresponds to or is less than half of the edge element 11 [Ad. For example, the connecting portions 23 are made with a height which is greater than a width of the connecting portions 23, so that the elongation of the respective connecting portion 23 exceeds the distance between the first portion 20 and the second portion 21.
    The connecting portions 23 extend transversely through the insulating layer 22 to connect the first portion 20 to the second portion 21. Thus, the insulating layer 22 is formed with a plurality of through holes for the connecting portions 23. The connecting portions 23 are formed to provide a load transfer portion for the connecting portion 20. and the second portion 21, said that the insulating layer 22 may be made of a highly insulating material with low load-bearing and load-transferring capacity. For example, the connecting portions 23 are integrated with the first portion 20 and the second portion 21.
    The connecting portions 23 comprise load-bearing or load-transferring materials and are designed to provide a stable connection between the first portion 20 and the second portion 21. For example, the connecting portions 23 comprise reinforcement, such as steel bars or the like. According to one embodiment, the connecting portions 23 comprise the first material. The connecting portions 23 comprise, for example, slatted clinker, such as cement-bonded slatted clinker or slatted concrete. For example, the connecting portions 23 are made of reinforced lightweight clinker concrete. For example, the first portion 20, the second portion 21 and the connecting portions 23 are made of the same material, i.e. the first material. For example, the first portion 20, the second portion 21 and the connecting portions 23 are cast in a continuous piece.
    As shown in Fig. 4 and Fig. 6, the connecting portions 23 are, for example, made with a rectangular cut surface in the longitudinal direction of the edge element 11, the hole transversely through the insulating layer 22 being made with a corresponding shape. The connecting portions 23 are thus designed in the form of steering blocks, which extend transversely through the tail in the insulating layer 22.
    The edge element 11 comprises, for example, an optional outer layer 24, as shown in Fig. 5 and Fig. 6. The outer layer 24 is made to form an external and visible part of the edge element 11 dA the building foundation 10 is finished.
    Thus, the outer layer 24 is applied to the second portion 21, the second portion 21 being arranged between the insulating layer 22 and the outer layer 24 so that the outer layer 24 forms the outer side 19 of the edge element 11. The outer layer 24 is for instance of slatted concrete. Alternatively, the outer layer 24 is of other suitable material, such as stone, concrete, plaster, paint or composite material.
    Referring to Figs. 7-9, an alternative embodiment of the invention is shown. In the embodiment shown in Figs. 7-9, the connecting portions 23 are made with a circular section surface in the longitudinal direction 11 of the edge element 11, which is shown by means of broken lines in Fig. 7. In the embodiment shown in Figs. 7-9, the connecting portions 23 are thus designed in the form of cylinders, for example with a diameter exceeding a distance between the first portion 20 and the second portion 21. In the embodiment shown in Figs. 7-9, the connecting portions 23 are arranged substantially centrally in height in the edge element 11. Alternatively, the connecting portions 23 are arranged closer to the lower side or the upper side 18 of the edge element 11. Alternatively, the connecting portions 23 are designed with a different shape in the sectional surface in the longitudinal direction of the edge element 11, such as an oval, square or other suitable lamp shape. In the embodiment shown, the connecting portions 23 are arranged in line with each other along the longitudinal direction of the edge element 11. Alternatively, the connecting portions 23 are arranged at different distances from the upper side 18 of the edge element 11 in the desired pattern.
    Referring to Figs. 10-12, an alternative embodiment of the invention is shown. In the embodiment shown in Figs. 10-12, the connecting portions 23 are distributed both in the longitudinal direction of the edge element 11 and in the vertical direction, a first set of connecting portions 23 being arranged above a second set of connecting portions 23 while forming a spacing distance therebetween. For example, the first set of connecting portions 23 are arranged in a lower part of the edge element 11, the second set of connecting portions 23 being arranged in an Owe part of the edge element 11. In the embodiment shown, the first set of connecting portions 23 are arranged parallel to the second the set of connecting portions 23 and are mutually offset in height, the connecting portions 23 having the first set being arranged directly above the connecting portions 23 in the second set. Alternatively, the first set of connecting portions 23 are offset in the longitudinal direction of the edge element 11 in relation to the second set of connecting portions 23. In the embodiment shown in Figs. 10-12, the connecting portions 23 challenge with a square sectional surface in the longitudinal direction of the edge element 11 but may be challenged elsewhere. sat, as described above.
    In the embodiment shown, the edge element 11 is made with a substantially rectangular cross-section and with a recess 25 in the corner between the inner side 17 and the upper side 18. The recess 25 in the embodiment shown is curved and extends along the edge element 11 in a conventional manner. The anchoring device 15 is arranged in the recess. The front of the recess 25 is the first portion 20, for example made in the form of a disc or a steering wheel block. The second portion 21 is, for example, made in the form of a disc or a steering wheel block. Possibly fringed the tail for receiving the bonding portions 23, the insulating layer 22 is, for example, made in the form of a disc or a steering wheel block.
