The invention relates to a segment for a building according to the features of the preamble of claim 1, a method for its production, a corner segment, a method for its production, a building and a method for its production.

From the prior art, as in the WO 2012/120021 A1 described a modularized mold element and a modular system for the production of structures of a plurality of modularized form elements known. The molded element is cast from polymer concrete.

The invention is based on the object, a relation to the prior art improved segment for a building, an improved over the prior art method for its preparation, a comparison with the prior art improved corner segment for a building, a comparison with the prior art improved method for its production, to provide a comparison with the prior art improved structure and an improved over the prior art method for its preparation.

The object is achieved by a segment for a building with the features of claim 1, a method for its preparation with the features of claim 6, a corner segment for a building with the features of claim 7, a method for its preparation with the features of claim 8, a building with the features of claim 9 and a method for its production with the features of claim 14.

Advantageous embodiments of the invention are the subject of the dependent claims.

A segment, in particular wall segment, for a building according to the invention comprises two side plates made of polymer concrete, between which a core element made of a foamed plastic is arranged. In particular, the core element is positively, materially and / or non-positively connected to the respective side plate. The segment according to the invention can be produced in a simple, rapid and cost-effective manner, in particular because high machine outputs and short casting times can be achieved for producing the polymer concrete side panels due to their simple shape, in particular as rectangular plates without contours and recesses. Thus, a high casting performance, a better utilization of machine capacity and a short production time are achieved for the production of the side plates. In addition, a significant material savings with respect to the polymer concrete and its components is achieved, in particular compared to wall blocks made of polymer concrete. The production of the segment according to the invention is particularly resource-conserving, so that a very good ecological footprint is achieved.

Furthermore, a simple assembly of the segments for the construction of the structure is made possible. In particular, due to a low weight of the segments advantageously no lifting technology is required. The segments allow in particular a very economical production of buildings.

The segment according to the invention furthermore has a very low U value. The U value is a measure of the thermal insulation properties of components. By means of the segment according to the invention thus a particularly good thermal insulation is achieved. This is achieved in particular by the sandwich construction realized by means of the solution according to the invention, ie two polymer concrete side panels which are separated from one another by the foamed plastic core element interposed therebetween, thereby significantly improving thermal insulation. In contrast, known from the prior art wall blocks made of polymer concrete especially in head areas and on the front side a continuous wall cross-section made of polymer concrete. This has a negative effect on the U value, since thermal bridges are thereby formed. In order to achieve an acceptable U-value, walls formed by means of such building blocks must be designed to be highly oversized statically and / or additional insulation measures must be carried out in order to achieve the required insulation values. This is avoided by the solution according to the invention.

The core element is advantageously formed of expanded polystyrene. As a result, an efficient, in particular simple and cost-effective, production of the segment is made possible and good static properties and thermal insulation properties are achieved. Alternatively, the core element is formed for example of another foamed plastic, for example made of foamed polypropylene or foamed polyurethane.

Advantageously, the core element and the two side plates have the same height and width, wherein the side plates, in particular in the same height direction and width direction and by a same Höhenrichtungsverschiebewert and Breiterichtungsverschiebewert to the core element offset from the core element are arranged. It is thereby achieved that the two side plates protrude beyond the core element in a corner region and in the adjoining high side region and broad side region of the segment, whereby a groove for a tongue and groove is formed between the two side plates, in particular between the regions of the two side plates projecting beyond the core element More specifically, a groove on the high side and the broad side, starting from this corner region, and the core element in the diagonally opposite corner region and the adjoining high side region and broad side region of the segment projects beyond the two side plates, whereby the core element, in particular its Over the side plates projecting area, a spring for the tongue and groove joint forms, more precisely, each one spring on the high side and the broadside, starting from this corner area. Thus, it is possible to arrange such segments one above the other and next to each other and to connect with each other by means of these tongue and groove connections. As a result, in particular thermal bridges between adjoining segments of the structure are avoided.

The core element is in particular as a single, d. H. separate, ingredient manufactured, d. H. it is not formed between the two side plates, in particular not by interspersing of the plastic, but it is formed as a separate component and thus only then arranged between the two side plates and positively, materially and / or non-positively connected to the respective side plate.

Advantageously, the side plates are each glued to the core element, in particular by means of an additional adhesive, d. H. not by forming the core element between the two side plates. As a result, a simple, fast and secure connection of the side plates is achieved with the core element. In particular, cavities between the core element and the side plates are avoided in which, for example, water, dirt or animals could penetrate. Thus, a long shelf life of the segment is ensured.

Advantageously, anchoring elements are arranged in the core element and in the side plates, for example made of plastic, by means of which the side plates are each connected to the core element positively and / or non-positively. The core element and the side plates each have at least one anchoring element or advantageously a plurality of such anchoring elements, which are distributed in the height direction and / or width direction in order to achieve a planar anchoring of the side plates on the core element. In the core element, the anchoring elements are advantageously foamed, ie they are already in the formation of the core element by foaming of the plastic in this integrated and are thus advantageously at least cohesively connected to this. These anchoring elements in the core element are advantageously designed in each case as a connection carrier which extends through the core element. As a result, the side plates are connected not only to the core member but also to each other. As a result, in particular a stiffening of the segment is achieved, as a result of which the static properties of the segment are improved. The anchoring elements on the side plates are advantageously cast in the polymer concrete of the respective side plate and thereby connected to the respective side plate at least cohesively.

Advantageously, the core element has at least one passage opening extending in the height direction. This passage opening serves to pass a threaded rod or another element for clamping a plurality of superimposed segments. As a result, a required stability and a backup against a pull-off force are achieved by suction.

In a method according to the invention for the production of such a segment, two polymer concrete side panels are cast and connected to a core element formed from a foamed plastic, in particular from expanded polystyrene, in a form-fitting, materially bonded and / or force-locked manner. As a result, the above-described advantages are achieved by means of the method for producing the segment. The at least one passage opening is formed, for example, during the formation of the core element, for example by means of a corresponding casting core in a casting mold for forming the core element, or after the formation of the core element introduced into this, for example by drilling or punching.

An inventive corner segment comprises two angled polymer concrete side plates, between which an angled core element is arranged made of a foamed plastic, wherein the angled core element positively, materially and / or non-positively connected to the respective angled side plate.

As a result, the above-described advantages are achieved by means of the method for producing the segment.

Also in the corner segment, the angled core element is advantageously formed of expanded polystyrene. As a result, an efficient, in particular simple and cost-effective, production of the angled corner segment is made possible and good static properties and thermal insulation properties are achieved. Alternatively, the angled core element is formed for example of another foamed plastic, for example made of foamed polypropylene or foamed polyurethane.

Furthermore, an outer side of a first angle leg of the angled core element has a smaller width and an outer side second angle leg of the angled core member has a greater width than the respective adjoining portion of an angled side plate and an inner side of the first angle leg of the angled core member has a smaller width and an inner side of the second angle leg of the angled core member has a greater width than the respectively adjacent thereto Area of the other angled side plate, whereby the angled side plates protrude beyond the first angle leg, advantageously to the same extent, and the second angle leg protrudes beyond the angled side plates, advantageously to the same extent with respect to the two angled side plates.

This ensures that, analogous to the segment described above, in particular wall segment, also in the corner segment a groove for a tongue and groove joint is formed, more precisely, in each case a groove on a high side and a broadside, and the angled core element, in particular its over the angled side plates projecting area forms a spring for the tongue and groove joint, more precisely, in each case a spring on the other high side and the other broadside. Thus, it is possible to arrange such corner segments one above the other and to arrange a segment described above, in particular wall segment, on both sides of the corner segment, and to connect by means of these tongue and groove connections. As a result, in particular thermal bridges between adjoining corner segments and between the corner segment and the respectively adjacent segment, in particular wall segment, of the building are avoided.

The angled core element is made especially as a single, ie separate, component, ie it is not formed between the two angled side plates, in particular not by interposing the plastic, but it is formed as a separate component and thus only then between the two angled side plates arranged and positively connected, cohesively and / or non-positively connected to the respective angled side plate.

Advantageously, the angled side plates are each glued to the angled core element, in particular by means of an additional adhesive, d. H. not by forming the angled core member between the two angled side panels. As a result, a simple, fast and secure connection of the angled side plates is achieved with the angled core element. In particular, cavities between the angled core element and the angled side plates are avoided, in which, for example, water, dirt or animals could penetrate. Thus, a long durability of the corner segment is ensured.

Advantageously, in the angled core element and in the angled side plates anchoring elements are arranged, for example made of plastic, by means of which the angled side plates are each connected to the angled core element positively and / or non-positively. The angled core element and the angled side plates each have at least one anchoring element or advantageously a plurality of such anchoring elements, which are arranged distributed in the vertical direction and / or width direction in order to achieve a planar anchoring of the angled side plates on the angled core element. In the angled core element, the anchoring elements are advantageously foamed, ie they are already integrated in the formation of the angled core element by foaming of the plastic in this and are thus advantageously at least cohesively connected thereto. These anchoring elements in the angled core element are advantageously designed in each case as a connection carrier which extends through the angled core element. As a result, the angled side plates are not only connected to the angled core element, but also with each other. As a result, in particular a stiffening of the corner segment is achieved, whereby static properties of the corner segment are improved. The anchoring elements on the angled side plates are advantageously in the polymer concrete of the respective angled Cast side plate and thereby connected to the respective angled side plate at least cohesively.

Advantageously, the angled core element has at least one passage opening extending in the vertical direction, in particular at least two such passage openings. This passage opening serves to pass a threaded rod or another element for clamping a plurality of superimposed corner segments. As a result, a required stability and a backup against a pull-off force are achieved by suction.

An inventive construction comprises a plurality of such segments and / or at least one such corner segment, in particular a plurality of such segments and, for example, at least one such corner segment or a plurality of such corner segments. By means of the segments and advantageously of the at least one or more corner segments, the structure can be formed in a simple, cost-effective and rapid manner, and the advantages already described above are achieved.

In particular, in each case at least two segments are arranged one above the other and clamped together by means of a guided through the passage opening of the segments threaded rod. As a result, a required stability and a backup against a pull-off force are achieved by suction.

The at least one corner segment is in particular arranged between two segments which are oriented at an angle of greater than 0 ° and less than 180 °, in particular at an angle of 90 °, to one another. As a result, a corner region of the building is formed.

The structure comprises, for example, a foundation, in particular with at least one anchoring receptacle for the threaded rod, for example a dowel and / or anchor, for example, embedded in the foundation, with which the threaded rod for bracing the or the segments and / or the or the wall segments can be connected. For example, the building comprises at least one base strip, also referred to as a base bar, in particular formed of polymer concrete, which in particular at least one through hole, for example, bore and / or slot, for the threaded rod and / or has at least one threaded sleeve for the threaded rod. For example, the building comprises at least one end segment, for example formed from polymer concrete, which in particular has at least one through hole for the threaded rod. For example, the building comprises at least one connecting element for connecting at least two end segments.

In a method according to the invention for producing such a structure, a plurality of such segments are arranged next to one another and / or one above the other. As a result, the above-mentioned advantages are achieved by means of the method for producing the structure.

Advantageously, at least two segments at an angle of greater than 0 ° and less than 180 °, in particular at an angle of 90 °, arranged aligned with each other and between a corner segment is arranged.

In an advantageous embodiment, the building comprises a plurality of segments, in particular wall segments, and corner segments, and one or more base strips and a plurality of end segments. The structure is erected on the foundation, advantageously on a strip foundation or concrete slab. The base bar is, in particular for the wall structures by means of the segments and corner segments, applied to the foundation or on the finished structure, it is applied thereto. The base strip is formed in particular of polymer concrete. Dimensions of the base bar, in particular a thickness and height, correspond to dimensions of the groove in the segments and corner segments, in particular their depth and width. The basic bar thus forms the spring for this groove to form the tongue and groove connection between the base strip and the respective segment or corner segment. The application of the base strip on the foundation, for example, by means of one or more dowels and / or anchor bolt and / or by gluing. The segments, in particular wall segments, and corner segments are placed vertically on the base strips, or they are in the finished structure, and can be glued to increase stability, for example, in addition to each other and with the base bar or glued in the finished structure.
The end segment is applied to the segments and / or corner segments, in particular via the spring formed in the segments and / or corner segments in the manner described above, or is applied thereto in the finished structure.

The terminating segments are connected to one another by means of connecting elements, for example strip steel or similar connecting elements, in particular connected non-positively and / or positively, or are in the finished building. Advantageously, bolts can be cast into the end segments for this purpose. Thus, the conditions, in particular the static requirements of a ring anchor are met.

The terminating segments have, for example, a continuous groove-like depression, in particular for arranging the connecting elements, for example for sinking the strip steel and nuts and / or washers. In this area, in particular in the groove-like depression, advantageously also the bolts are cast.

This described construction and assembly of the building allows, in particular in the variant without additional bonding of the components of the structure, in particular without bonding of baseboards and foundation and / or baseboards and segments and / or corner segments and / or without gluing the segments and / or corner segments with each other and / or without gluing the end segments with the segments and / or corner segments, a non-destructive dismantling and / or multiple assembly and disassembly, in particular repeated use of the individual components of the structure, for example, for other spatial concepts.

For the above-mentioned polymer concrete, in particular for its production, in particular a curable plastic, for example polyester resin, is used as binder. For example, inferior sands and / or wastes, especially waste products, and / or recycled material, for example, crushed glass fiber reinforced plastic (GRP) and / or recycled polymer concrete and / or the like, are used as solid fillers for the production of the polymer concrete, especially materials which are used in the cement-bonded construction industry can not be used.

The FIGS. 1 to 8 show schematic representations of a segment 1, in particular a wall segment, for a building 18. Here, the segment 1 in FIG. 1 in a plan view, in particular on a front side, shown in FIG FIG. 2 in a high-side view, in FIG. 3 in a broadside view, in FIG. 4 in a perspective view, in FIG. 5 in a sectional view corresponding to the sectional plane VV in FIG. 1 , in FIG. 6 in a sectional view corresponding to the sectional plane VI-VI in FIG. 1 , in FIG. 7 in a detailed representation according to the details VII in FIG. 5 and in FIG. 8 in a perspective view of the sectional view FIG. 5 , The FIGS. 9 and 10 show schematic representations of a corner segment 15 to form a corner region of such a structure 18, wherein FIG. 9 the corner segment 15 in a perspective view and FIG. 10 shows the corner segment 15 in a plan view from above. FIG. 11 shows one schematic sectional view of a wall of a producible by means of such segments 1 building 18th

The segment 1 comprises two separate side panels 2 of polymer concrete, between which a core element 3, in particular a core plate, of expanded polystyrene (EPS) or of another foamed plastic is arranged, for example of foamed polypropylene or foamed polyurethane. The core element 3 is expediently positively, materially and / or non-positively connected to the respective side plate 2.

In the illustrated example, the side plates 2 are each glued to the core element 3. Furthermore, anchoring elements 4, 5 are arranged in the core element 3 and in the side plates 2, by means of which the side plates 2 are in each case positively connected with the core element 3 and, for example, also with a force fit. These anchoring elements 4, 5 are arranged distributed in height direction H and width direction B, in order to achieve a surface-distributed anchoring of the side plates 2 on the core element 3.

The anchoring elements 4 in the core element 3 are designed as connection carriers, which are foamed into the core element 3, d. H. be enclosed during the production of the core element 3 of the foamed plastic. They each extend in the thickness direction D through the core element 3. As a result, the side plates 2 are connected to one another not only with the core element 3 but also via its anchoring elements 4 formed as a connection carrier through the core element 3.

These anchoring elements 4 of the core element 3 designed as connection carriers thus serve, in particular together with the anchoring elements 5 of the side plates 2, the connection of the side plates 2 with each other and with the core element 3 and also the stiffening of the segment 1, whereby static properties of the segment 1 are improved.

The core element 3 has, for example, a thickness of 160 mm, but in other embodiments of the segment 1 may also have a greater or lesser thickness, for example as a function of static requirements and / or thermal insulation requirements.

The anchoring elements 5 in the respective side plate 2 are advantageously cast in the polymer concrete of the respective side plate 2. For example, these anchoring elements 5 are each designed as a suspension lug or hooks to mount the correspondingly formed respective anchoring element 4 of the core element 3 therein.

As in particular in FIG. 7 1, a respective region of the respective anchoring element 4 of the core element 3 projecting from the core element 3 is bent downwards in a hook shape, and a region of the respective anchoring element 5 of the respective side plate 2 projecting from the respective side plate 2 is bent hook-shaped upwards. As a result, the side plates 2 can be connected positively and, for example, non-positively by being applied to the core element 3 and displaced upward until these hook-shaped regions 6, 7 of the anchoring elements 4, 5 interlock, as in FIG FIG. 7 shown.

As further in FIG. 7 and also in the Figures 5 . 6 and 8th can be seen, the anchoring elements 4 of the core member 3 each have at least one toothing 8, advantageously, as shown here, a plurality of teeth 8, ie at right angles from a connecting web 9 of the respective anchoring element 4 protruding formations to ensure a good support in the foamed plastic.

The segment 1 thus comprises three essential components in the form of the two side plates 2 and the core element 3, which form a static system with predetermined static properties only in the interconnected state.

The side plates 2 and the core element 3 have the same height and width, for example, a height of 1400 mm and a width of 300 mm. The side plates 2 each have, for example, a thickness of 20 mm.

The side plates 2 are arranged in the same height direction H and width direction B and offset by a same Höhenrichtungsverschiebewert and width direction shift value, for example, each 30 mm to the core element 3 offset on the core element 3, in particular in FIG. 1 can be seen in which the core element 3 and the front side plate 2 arranged displaced thereon can be seen. The rear side plate 2 is displaced in the same way to the core element 3 and is therefore in the illustration according to FIG. 1 , which shows the segment 1 in plan view from the front, completely covered by the front side plate 2.

By this shifted arrangement of the side plates 2 on the core element 3 is achieved that the two side plates 2 in a corner region, in FIG. 1 in the lower right corner region, and in the adjoining high-side region and broad-side region of the segment 1 project beyond the core element 3, whereby a groove N for a tongue and groove connection is formed between the two side plates 2, as in FIGS FIGS. 2 to 6 and 8th can be seen, and the core element 3 in the diagonally opposite corner area, in FIG. 1 in the upper left corner region, and in the adjacent high side region and broad side region of the segment 1 projects beyond the two side plates 2, whereby the core element 3, in particular its over the side plates 2 projecting region, a spring F forms the tongue and groove connection, as well in the FIGS. 2 to 6 and 8th seen. Thus, it is possible to arrange such segments 1 one above the other and next to each other and to connect with each other by means of these tongue and groove joints by the spring F of engages a segment 1 in the groove N of the adjacent segment 1. Ie. juxtaposed and superimposed segments 1 engage with each other. As a result, in particular thermal bridges between adjoining segments 1 of the structure 18 are avoided.

The core element 3 has a passage opening 10 extending in the height direction H. This passage opening 10 serves to pass a threaded rod 14 or another element for clamping a plurality of superposed segments 1 to form the structure 18th

In the process for producing the segment 1, the side plates 2 are cast from polymer concrete, advantageously the anchoring elements 5 are cast. Furthermore, the core element 3 is made of foamed plastic, in particular of expanded polystyrene, wherein the anchoring elements 4 are foamed by the plastic of the core element 3.

For connecting the side plates 2 to the core element 3 to be joined contact surfaces of the core member 3 and / or the side plates 2 are provided with adhesive and the side plates 2 and the core element 3 are assembled, wherein the anchoring elements 4, 5 are interconnected, for example, be hooked and there is a compression, d. H. a pressing of the side plates 2 to the core element 3, to ensure the bonding.

The side panels 2 are easy, fast, inexpensive and economically efficient to manufacture. In particular, a high engine output of, for example, 60 Kg / min. can be achieved, since the side plates 2 are each formed as a straight rectangular plate, advantageously without contours and recesses. For example, weigh the side plates 2 each 17.5 kg, for example, at the same time five side plates 2 in one Molded battery can be produced. For example, a pour time, ie, pouring the mixed and uncured polymer concrete into a mold, is only 87.5 seconds per mold battery (17.5 seconds per side plate 2). The casting time, for example, is only 84.5 seconds per square meter by means of the segments 1 wall surface to be formed. It is thus achieved, for example, compared to wall blocks made of polymer concrete four times the casting capacity and thus a correspondingly high utilization of machine capacity and a corresponding reduction in production time.

Furthermore, a significant material savings with respect to the polymer concrete and its components is achieved, in particular compared to polymer concrete wall blocks. For example, polymer concrete blocks require 172.2 Kg of polymer concrete per square meter of wall area to be formed and only 84 Kg of polymer concrete per square meter of wall surface to be formed, ie. H. a material saving of 51%.

For the polymer concrete, for example, a resin is used which has a mass fraction of 40% to 45%, in particular 43%, of styrene. The resin is, for example, a terephthalic acid polyester resin which has, for example, a mass fraction of 38% polyethylene terephthalate (PET), in particular of recycled material.

Based on the resin content in the mixed polymer concrete to be cast, the mass fraction of a curing agent in the mixed polymer concrete to be cast is for example 2% and the mass fraction of the accelerator is 1.6%, for example. H. the mass of the hardener and the accelerator are each calculated based on the mass of the resin. The accelerator is for example a cobalt accelerator or a mixing accelerator. In particular, a cobalt-amine accelerator is used as the mixing accelerator.

A grading curve of one or more fillers is for example up to 5 mm.

The mold is preheated, for example, prior to filling the mixed and not yet cured polymer concrete, for example to a temperature of at least 22 ° C, for example to a maximum temperature of 25 ° C, for example to a temperature of 22 ° C to 25 ° C. The curing of the polymer concrete takes place for example by annealing in a heat chamber.

It is used a release agent which is sprayable and has at least one wax. In this case, a mass fraction of the at least one wax, for example, 12%. The release agent, before the mixed and not yet cured polymer concrete is poured into the mold, applied to the mold and facilitates demolding of the respective side plate 2 after curing of the polymer concrete.

The production of the side plates 2 thus requires no complex manufacturing technology and only simple molds are needed. For example, the molds are in the form of battery shapes. In this case, a base plate and a cover plate are respectively introduced into a base frame for a plurality of side plates 2 to be produced, for example for six side plates 2. The side plates 2 are then poured together.

For pouring the anchoring elements 5 in the polymer concrete of the side plates 2, the anchoring elements 5 are screwed, for example, to the respective base plate and thus poured into the mold by filling the polymer concrete in this. During the demolding of the respective side plate 2, the connection of the respective anchoring element 5 is released with the base plate and the cast side plate 2 is taken out of the mold. This allows a higher casting performance of the machine and thus a shorter production time and low production costs.

A structure 18 produced by means of such segments 1 has a plurality of such segments 1. In particular, by means of these segments 1 in a method for producing the structure 18, a wall or several walls, for example a building, are formed. In this case, advantageously at least two or more such segments 1 are arranged one above the other per storey height, d. H. in the height direction H one above the other, wherein a threaded rod 14 is passed through the through holes 10 of the superimposed segments 1, by means of which these segments 1 are braced. In other embodiments, with sufficient height of the segments 1, for example, only one segment 1 per storey height in the vertical direction, d. H. in the height direction H, be provided. Also, a fixing by means of the guided through the through hole 10 threaded rod 14th

The segments 1 are, for example, placed on baseboards 12, which, for example threaded sleeves for screwing the threaded rods 14 for the vertical clamping of the segments 1 have. Furthermore, these base strips 12, for example threaded sleeves for a connection of the base strips 12 with each other, for example by means of steel strip.

For example, end segments 13, in particular ring beam elements, are placed with through holes for passing through the threaded rods 14 as the top end of the wall of the respective projectile of the building 18. The individual ring beam elements are connected to each other analogous to the base strips 12, so that the effect of a ring anchor is achieved. The bracing of the wall and the security of the stability takes place via the threaded rods 14, which are screwed into the base strips 12 and tightened on the formed of the ring beam elements ring beam, for example by means of a nut / countered.

To form the wall a plurality of such segments 1 are arranged side by side, ie in the width direction B next to each other. The side by side and superimposed segments 1 are arranged in such a way that the tongue and groove connection between each two adjacent segments 1 is formed by the spring F forming over the side plates 2 projecting edge region of the core member 3 of a segment 1 in the groove N, which is formed by the over the core element 3 protruding edge region of the side plates 2 of an adjacent segment 1, engages.

This assembly of the segments 1 for the production of the structure 18 is particularly simple and, in particular, no lifting technology is required due to the low weight of, for example, only 35.2 kg of the respective segment 1, so that the production of the structure 18 by means of these segments 1 particularly cost effective and efficient is.

Due to the described design of the segments 1 and the meshing of adjacent segments 1 via the tongue and groove connection, a particularly low U-value of, for example, below 0.24 W / (m ² K) is achieved, whereby, for example, specifications of an energy saving regulation are met. Moreover, there are no thermal bridges over the entire wall surface. The described production of the segments 1 and the structure 18 is particularly resource-friendly, whereby a very good life cycle assessment and thus a very good ecological footprint is achieved.

The FIGS. 9 and 10 show, as already described, a corner segment 15 for the structure 18. This is, at least substantially, formed in the same manner as the segment 1, only angled, in particular by 90 °. The, at least substantially, same training applies in particular to the polymer concrete for producing the angled side elements and the plastic for producing the angled core member 17, and the formation of the grooves N and springs F and the through hole 10 or through holes 10. The respective groove N of Corner segment 15 is in particular corresponding to the respective spring F of the segment 1, which is to be connected therewith formed. The respective spring F of Ecksegments 15 is in particular corresponding to the respective groove N of the segment 1, which is to be connected thereto formed. Furthermore, in particular, the passage openings 10 of the corner segments 15 and segments 1 are formed correspondingly in order to use the same threaded rods 14 can.

The corner segment 15 thus comprises two angled side plates 16 made of polymer concrete, between which an angled core element 17 is arranged made of a foamed plastic, wherein the core element 17 is positively, materially and / or non-positively connected to the respective angled side plate 16. This corner segment 15 serves in particular the connection of two above-described segments 1 over corner, in particular for the formation of a corner region of the structure 18th

In the method for producing the corner segment 15, two angled polymer concrete side plates 16 are cast and positively connected to the angled core member 17 made of the foamed plastic, cohesively and / or non-positively.

The angled core element 17 is advantageously made of expanded polystyrene or of another foamed plastic, as described above for the segment 1, for example of foamed polypropylene or foamed polyurethane.

Analogous to the above-described advantageous embodiment of the segment 1, in particular wall segments, advantageously also in the corner segment 15, the angled core member 17 and the two angled side plates 16 the same height, wherein the angled side plates 16 in particular in the same height direction H and a same Elevation direction shift value to the angled core element 17 offset from the angled core element 17 are arranged. Furthermore, an outer side of a first angle leg of the angled core element 17 a smaller width and an outer side of a second angle leg of the angled core member 17 has a greater width than the respectively abutting portion of an angled side plate 16 and an inner side of the first angle leg of the angled core member 17 has a smaller width and an inner side of the second angle leg of the angled Core member 17 has a greater width than the respective adjoining portion of the other angled side plate 16, whereby the angled side plates 16 protrude beyond the first angle leg, advantageously to the same extent, and the second angle leg protrudes beyond the angled side plates 16, advantageously to the same extent Both angled side plates 16. It is thereby achieved that, analogous to the above-described segment 1, in particular wall segment, also in the corner segment 15, a groove N is formed for a tongue and groove connection, More specifically, a groove N on a high side and a broad side, the angled core member 17, in particular its over the angled side plates 16 projecting region forms a spring F for the tongue and groove joint, more precisely, in each case a spring F on the other high side and the other broadside. Thus, it is possible to arrange such corner segments 15 one above the other and to arrange on each side of the corner segment 15 each have a segment 1 described above, in particular wall segment, and to connect by means of this tongue and groove connections.

FIG. 11 shows a construction of the structure 18 using the example of a wall of the structure 18, which is shown here in a sectional view. The training is advantageously carried out as already described above. The structure 18 is erected on a foundation 11, advantageously on a strip foundation or a concrete slab. On the foundation 11 formed from polymer concrete base bar 12, also referred to as the base bar, with the dimensions corresponding to the groove N, applied, for example by means of dowels, anchor bolts and / or glued for the wall structures.

In this base strip 12 through holes, such as holes and / or slots, introduced for performing the threaded rods 14. In the underlying areas 11 anchoring shots, such as dowels and / or anchors, are embedded in the foundation, with which the threaded rods 14 are connected for bracing the segments 1 and corner segments 15. The segments 1 and corner segments 15 are placed vertically on the base strips 12 and can be glued to increase the stability in addition to each other and with the respective base bar 12.

On the wall segments end segments 13 are applied via the spring F. These are provided with through holes for performing and clamping the threaded rods 14. The end segments 13 are connected by means of connecting elements, such as steel strip or similar fasteners, each other positively and / or positively. Advantageously, bolts can be cast into the end segments 13 for this purpose. Thus, the conditions, in particular the static requirements of a ring anchor are met.

For the fasteners, the end segments 13 are provided with a continuous groove-like recess 19 for countersinking the steel strip and nuts and / or washers for the threaded rods 14, in this area, the bolts are cast. This type of construction and assembly allows the variant without additional bonding a non-destructive dismantling, respectively, a multiple assembly and disassembly or the repeated use of the individual elements for other room concepts.
