Description

[0001] Cuboidal component, method for producing a component and system comprising two cuboidal components

[0002] The invention relates to a cuboidal component, a method for producing a substantially cuboidal component, and a system comprising at least two cuboidal components and a connecting element according to the independent claims.

[0003] The construction of buildings often requires prior technical expertise, so the cost of services often exceeds the cost of materials many times over. Private individuals can generally only contribute to the construction of buildings to a limited extent, as arranging and aligning the building materials, particularly the load-bearing structures such as walls and foundations, requires a great deal of labor, and incorrect arrangements are difficult to correct. Furthermore, construction projects using conventional building materials often require a variety of equipment to which private individuals do not have access, or which at least entails substantial financial costs.

[0004] Repair work and / or extension projects often involve considerable effort and / or cannot be carried out flexibly according to one's own design ideas.

[0005] In addition, the cost of building materials is often very high, preventing affordable housing from being accessible to a large number of people.

[0006] In the state of the art, various elements for use as building materials are known. However, there is generally a lack of a simple, intuitive, user-friendly, and fast

[0007] REVISED SHEET (RULE 91) ISA / EP Method of use for arranging the components relative to each other and for fixing the components, in particular without additional equipment.

[0008] For example, US 2004 / 000114 A1 shows modular building elements that have passages so that the elements can be fixed relative to one another. However, the use of these elements is complicated and requires concrete and structural steel for fixation.

[0009] The object of the present invention is to overcome these and other disadvantages of the prior art. In particular, it is intended to provide a simple and cost-effective component for use as a building material.

[0010] This object is achieved by a component defined in the independent claims, a method for producing a component, and a system. Further embodiments emerge from the dependent claims.

[0011] A substantially cuboid-shaped component according to the invention comprising at least partially plastic and four side surfaces which are vertically aligned in an installed position. The side surfaces each have at least one receiving structure. In the installed position, an upper side of the component has a male connecting element and a lower side has a female connecting element, or the upper side has a female connecting element and the lower side has a male connecting element. The male connecting element and female connecting element are shaped complementarily to one another.

[0012] REVISED SHEET (RULE 91) ISA / EP Complementary shaped to one another defines in this context an at least partially form-fitting connection possibility of the elements which are shaped complementarily to one another.

[0013] The component may consist of or comprise thermosets or thermoplastics.

[0014] In particular, the component can consist of or comprise thermosetting plastics such as hardened synthetic resins or hardened prepolymers.

[0015] In particular, the component can consist of or comprise thermoplastic materials such as polyolefins, particularly preferably polypropylene and / or polyethylene, polymethyl methacrylate, or polystyrene.

[0016] The component can also consist of 50%, preferably 90%, particularly preferably substantially completely, of plastic.

[0017] The component may also comprise fillers and / or dyes.

[0018] The cost of the building elements can be reduced by using inexpensive fillers, such as quartz sand. Dyes can be adapted to the user's aesthetic preferences or used to mark different building blocks to improve their recognition.

[0019] The component can be made from at least partially recycled plastic to reduce costs.

[0020] The building element can include fire protection, thermal insulation, and / or sound insulation materials. The enclosed air within the building element also has an insulating effect. In addition, insulation material can

[0021] REVISED SHEET (RULE 91) ISA / EP be installed outside or inside the building element. This has the advantage of avoiding the additional step of installing insulation.

[0022] Alternatively, separate insulation materials can be attached to the building element, preferably through a formwork or between a formwork of the building element.

[0023] The building element can be used for the construction of walls of buildings .

[0024] In the installed position, a structural element may have a horizontal recess for accommodating a support device, in particular a beam. The horizontal recess may extend continuously or only partially through the structural element. Thus, structural elements on two opposite sides of a wall can accommodate a support device, which can be used, for example, to support a mezzanine floor or ceiling, in particular mezzanine floor elements.

[0025] The at least one male connecting element and the female connecting element can be aligned longitudinally perpendicular to the underside and / or top side. In particular, the at least one male connecting element can be arranged on the top side in an installed position of the component. Such alignment and arrangement allow the components to be easily stacked in a slip-resistant manner and also to be transported in a space-saving manner.

[0026] The male and female connecting element can have a round, oval, polygonal, in particular regular polygonal shape in cross-section.

[0027] REVISED SHEET (RULE 91) ISA / EP An oval, polygonal, or regular polygonal shape of the connecting elements has the advantage that two different components cannot be rotated when the male and female connecting elements of two components are connected. This simplifies the linear arrangement of the components one above the other.

[0028] The top and / or bottom can each have one to ten connecting elements, in particular one to ten male or one to ten female connecting elements.

[0029] The component can be mirror-symmetrical along one or two planes. Such mirror symmetry simplifies the arrangement of the components relative to one another for the user.

[0030] The receiving structure can extend continuously in a straight line from a top side of the component to a bottom side of the component. Preferably, the receiving structure extends substantially in a vertical direction in the installed position of the component.

[0031] The receiving structure may have at least one recess extending over part or all of the side surface. The cross-section of the recess may include an undercut.

[0032] The cross-section of the recess can be L-shaped, T-shaped, O-shaped, Z-shaped, dovetail-shaped, trapezoidal, knob-shaped, oval, and / or curved. Such a cross-section allows two components to be connected, preferably by essentially form-fitting connections, by inserting a connecting element, in particular a connecting bar. Such a connection can be

[0033] REVISED SHEET (RULE 91) ISA / EP counteract the force acting perpendicular to the joined faces which pushes the two structural elements apart.

[0034] The receiving structure may have at least two recesses, in particular three, four, five, or six recesses. The longitudinal axes of the recesses may run parallel and spatially spaced from one another.

[0035] The undercuts of the recesses can extend in the cross-section toward the adjacent recess. Such undercuts allow the recesses to be spaced further apart from one another on the side surface. The distance between two recesses can be between 2 cm and 30 cm, in particular 20 cm. A larger distance between the recesses allows for better compensation of the transverse forces acting on structural elements or connecting elements.

[0036] The receiving structures can have a recess that has a straight longitudinal axis and that runs partially or completely parallel to the recesses in the longitudinal direction. This recess can be suitable for receiving a connecting bar of a connecting element, so that the connection between two components can be additionally reinforced.

[0037] The receiving structure may have a recess in addition to the cutout or as an alternative to the cutout. The recess may be designed to accommodate a connecting bar and / or a cable.

[0038] A further object of the present invention is to provide a building element which enables the laying of cables in the wall and at the same time provides an aesthetically pleasing, flush wall surface.

[0039] REVISED SHEET (RULE 91) ISA / EP The cuboidal component can be a component as described above. The component comprises four vertically aligned side surfaces in one mounting position of the component.

[0040] At least two, preferably three or four, of the side surfaces each have a receiving structure.

[0041] At least two, preferably three or four, of the receiving structures comprise at least one recess for receiving at least one connecting element for the connection to an adjacent building element or a wall panel.

[0042] At least one of the receiving structures, preferably a receiving structure with a recess for receiving at least one connection element, has a recess for receiving a cable. The recess is arranged, preferably centrally, such that recesses of stacked components are aligned, thus forming a continuous receptacle for a cable.

[0043] The recess extends from one side surface to an opposite side surface. Such a recess can be particularly advantageous in combination with the above-described embodiments with receiving structures for receiving at least one connection element on all four side surfaces. It is understood that such recesses for receiving a cable can also be advantageous in connection with other types of connections between individual components.

[0044] In the installation position, a top side of the component can have a male connection element and a bottom side a female connection element or the top side can have a female

[0045] REVISED SHEET (RULE 91) ISA / EP connecting element and the underside has a male connecting element.

[0046] The male connecting element and female connecting element can be shaped complementarily to each other.

[0047] The upper side of the component can comprise a step, preferably a step between at least one of the side surfaces and the upper side, so that components arranged one above the other form an at least partially enclosed cavity. The cavity borders on a recess, preferably at least two recesses.

[0048] The step can extend at least partially or completely along a circumferential direction of the component. Arranging the step in the circumferential direction allows electrical lines to be routed in a horizontal direction in an installed position of the component.

[0049] The step can extend along an outer edge formed by the top and side surfaces of the component. Thus, the step is easily accessible, and a connecting element, preferably with at least one connecting bar, can be easily attached.

[0050] The component may comprise a passage having a longitudinal axis which is oriented straight, preferably vertically, in the installed position and extends from the top to the bottom.

[0051] Such a passage offers the advantage that a water pipe, an electrical line, a radiator, and / or a support structure can be placed in the passage.

[0052] REVISED SHEET (RULE 91) ISA / EP A vertical passage in one installation position offers the advantage that several components arranged one above the other can form a connected passage.

[0053] The passage may be circular, elliptical or polygonal in cross-section, in particular regularly polygonal.

[0054] The passage has a maximum diameter of 3 cm to 15 cm or substantially 30 % , in particular 20 % , of the maximum side length .

[0055] The passage may form the female connecting element.

[0056] The passage may extend through the protruding portion of the male connector.

[0057] When the female and male connecting elements of two components, each with one passage, are connected, an aligned connection of the passages to each other can be ensured.

[0058] The longitudinal axis of the passage can run through a mirror axis of the component, preferably through the geometric center of gravity of the component. Thus, the user has less to consider the orientation of the passage when connecting components.

[0059] The component can be installed in the

[0060] - a height, measured in the vertical direction, in the range from 10 cm to 40 cm, in particular from 15 cm to 25 cm;

[0061] REVISED SHEET (RULE 91) ISA / EP - a width, measured from the farthest side surfaces, in the range 10 cm to 80 cm, in particular 15 cm to 50 cm;

[0062] - have a depth, measured in a direction perpendicular to the height and width, in the range from 10 cm to 40 cm, in particular from 15 cm to 25 cm.

[0063] The height is determined by the vertical height of the component, excluding the height of the male connecting element.

[0064] The essentially cuboid-shaped component can be manufactured by injection molding.

[0065] A further aspect of the invention relates to a system comprising at least two components, in particular components as described above, and a connecting element for substantially form-fitting connection to a receiving structure of one of the components and connecting two receiving structures of the components.

[0066] The other elements of the system can consist of or include the same materials as a previously described component.

[0067] The connecting element can comprise a head region with a central web which has at least one lateral flange, preferably two lateral flanges.

[0068] The two side flanges can be arranged on opposite sides of the head area.

[0069] The head region of the connecting element can have an at least partially rectangular, round, oval, dovetail-shaped, trapezoidal, double-T, or I-shape.

[0070] REVISED SHEET (RULE 91) ISA / EP The head region of the connecting element in the installed position can have essentially twice the horizontal width of the step of the component, preferably along the entire longitudinal axis of the head region. Such a head region is advantageous because the head region can thus be positively received by the steps of two components in order to fix two components relative to one another.

[0071] The central web may have a smaller width than the at least one lateral flange, in particular both lateral flanges.

[0072] The lateral flange can be materially connected to at least one connecting bar. A first lateral flange can be materially connected to a first connecting bar, and a second flange can be materially connected to a second connecting bar. The at least one connecting bar can be inserted in a substantially form-fitting manner into at least part of the receiving structures of two components simultaneously in order to connect the two components.

[0073] At least two, preferably three, connecting bars can be materially connected by the head region, so that they can be moved together, in particular can be inserted into the receiving structure by a translational movement. Thus, a single connecting element can connect several recesses and / or depressions of a receiving structure of one component to another receiving structure of another component.

[0074] The head section can be shorter in the horizontal direction than a horizontal side of the component. Such a head section has the advantage that despite the attachment of the connecting element

[0075] REVISED SHEET (RULE 91) ISA / EP furthermore power lines and heaters can be mounted horizontally in the step of the building element from one side surface to an opposite side surface.

[0076] The connecting bars can be attached in the outermost area of ​​the side flange.

[0077] The central web may also have a connecting bar for insertion into the recess of the receiving structure of the component.

[0078] The connecting bars can run at least partially parallel to each other. This has the advantage that several connecting bars can be inserted into the recess(es) and / or depressions of two components with a single translational movement in order to connect them.

[0079] The cross section of the connecting bar can have a complementary shape to two adjacently arranged recesses, in particular a double-L, double-T, double-C, double-Z, dovetail-shaped, trapezoidal-shaped, double-knob-shaped, double-oval, or curved shape.

[0080] A dovetail-shaped connecting bar is more rigid and allows a stable fixation of two components relative to each other using a single connecting bar.

[0081] Two connecting bars, especially L-shaped connecting bars, allow for a more flexible connection of components. Such connecting bars ensure that two components are still connected even if one connecting bar is damaged or defective.

[0082] REVISED SHEET (RULE 91) ISA / EP The steps, recesses, and indentations of the components can accommodate the connecting element in a substantially form-fitting manner. This simplifies the connection of two components with a connecting element and also minimizes the relative movement of the components.

[0083] The system may comprise at least one first cuboid-shaped component and at least one second cuboid-shaped component. The first component may be substantially half the size, one-third the size, or one-quarter the size of the second component. The first component may be substantially cube-shaped.

[0084] This has the advantage that stacked rows of building elements can be offset from one another while still being able to be positioned sideways at corners, door frames, and windows. A staggered arrangement of the building elements ensures greater stability.

[0085] The system may comprise a wall panel, and the wall panel may have a first connection region on a first side surface. The connection region may protrude from the side surface and be form-fittingly connectable to the receiving structure of the building element.

[0086] The connection area can be shaped so that the connection area can be connected to the recess of the receiving structure. However, the recess can remain free of obstructions when the wall panel is connected to the receiving structure, so that electrical and / or water lines can be routed through the recess while the wall panel is connected.

[0087] REVISED SHEET (RULE 91) ISA / EP The wall panel may also project laterally beyond at least one side surface of the building element so that two wall panels arranged at an angle to each other form a projecting corner.

[0088] A laterally projecting portion of the wall panel may have a miter so that the corner joint can be arranged at an angle.

[0089] The first connecting region of the wall panel can have a substantially complementary shape to the at least one recess and / or depression, in particular L-shaped, T-shaped, C-shaped, Z-shaped, dovetail-shaped, knob-shaped, oval, and / or curved. This has the advantage that the receiving structure is suitable both for connecting adjacent components by means of connecting elements and for attaching wall panels.

[0090] The receiving structures, in particular the recesses and depressions, of superimposed components can be arranged such that they extend along a common longitudinal axis. Such an arrangement has the advantage that elements, such as a formwork element, can be displaced from an upper end of a receiving structure of several superimposed components to a lower end of the several superimposed components along the receiving structure of the components.

[0091] The wall panels can be shaped so that the connecting area can be attached only to the at least one recess, leaving at least one recess or cutout of the component unfilled. This has the advantage that cables can be laid on one side surface of the component, and the wall panel can then be mounted over it.

[0092] REVISED SHEET (RULE 91) ISA / EP The wall panel connection area optionally does not extend over the entire length of the building element or has interruptions. This offers the advantage that cables, wires, or wall heating can be routed laterally to adjacent building elements in addition to the longitudinal axis of a recess or cutout. In particular, the cables, wires, or wall heating can be routed through a cavity created by the step in the building element when building elements are stacked on top of one another.

[0093] The wall panel can also have recesses to accommodate cables, pipes or wall heaters.

[0094] The wall panel may have widened sections that incorporate sound- or heat-insulating material. Such wall panels have the advantage that insulation is easy to install, replace, and, in particular, can be easily retrofitted or added later.

[0095] The opposite second side surface of the wall panel may form a substantially flat surface. The wall panel may then be used to cover the building element.

[0096] The system may comprise a separate formwork element. The wall panel may have a second connection area for attaching the formwork element on a second side surface opposite the first connection area.

[0097] The longitudinal axis of the second connecting region may extend partially or completely in the horizontal direction in an installed position of the wall panel. In an installed position of the wall panel, the second connecting region may be open upwards, in particular have an at least partially hook-shaped cross-section.

[0098] REVISED SHEET (RULE 91) ISA / EP. Such an arrangement has the advantage that the formwork elements can be fixed relative to the wall panel by gravity alone. Furthermore, the formwork elements are thus easy to install, as they can be inserted vertically from above into the second connection area.

[0099] The wall panel and / or formwork element may have substantially the same periphery as a side surface of the building element.

[0100] However, a periphery of the wall panels and / or the formwork elements can also extend over the side surface of several building elements.

[0101] The system may comprise a corner cladding element. The corner cladding element may have at least one connecting area, so that the corner cladding element can be connected to at least two receiving structures of adjacent side surfaces of a building element.

[0102] Alternatively, the connecting area of ​​the corner cladding element can be connected to two second connecting areas of two different wall panels.

[0103] Such corner cladding elements have the advantage that the cladding of the walls ends at the corners and is therefore aesthetically pleasing for the user.

[0104] An inner or outer side surface of the corner formwork element can essentially correspond to a full or half side surface of the building element. This allows for easier formwork of the wall with aligned formwork elements, as no additional formwork elements of different sizes need to be used.

[0105] REVISED SHEET (RULE 91) ISA / EP The system can comprise a substantially cuboid-shaped foundation component. The foundation component can have, on an upper side in an installed position, at least one recessed and / or protruding receiving area, preferably two, four, six, or eight recessed and / or protruding receiving areas for connection to a base element or building element. On the four side surfaces, the foundation component can have male and / or female connecting elements which are shaped complementarily to one another.

[0106] The foundation element can form a rectangular or square surface. The surface can have dimensions that correspond to the underside of the element. This has the advantage that the foundation element can be used modularly with the element.

[0107] The foundation element can have only male or only female fasteners on one side surface. This makes it easier to align the fasteners for connection.

[0108] The foundation element can have two or more male and / or female connecting elements per side surface.

[0109] The foundation component can have only male connecting elements on one side and only female connecting elements on the opposite side. This arrangement has the advantage that the user can more easily fix the foundation components relative to one another.

[0110] The male and female connecting elements can only be installed in one head area of ​​the four side

[0111] REVISED SHEET (RULE 91) ISA / EP surfaces. This has the advantage that the foundation elements only need to be raised slightly in order to connect the corresponding male and female connecting elements by vertical lowering.

[0112] The foundation element may have a cavity. The cavity may be connected to the top of the foundation element by a passage. This has the advantage that the cavity is accessible from above when a plurality of foundation elements are connected to form a surface.

[0113] The passage may also be shaped to accommodate an elongated reinforcement, particularly a steel or plastic strut or tube. This allows the reinforcement to be anchored to the foundation while simultaneously improving the structural integrity of the system, which may, for example, form a wall.

[0114] The foundation element can be open on one side in an installed position, or it can enclose the cavity on the bottom side. If the foundation element is open at the bottom, a surface on which the foundation element is placed can form the bottom side of the cavity. Such a cavity can save material for the foundation elements.

[0115] A cuboidal foundation component of the system can alternatively have on an upper side in an installed position at least one lowered and / or protruding receiving area, preferably two, four, six, or eight lowered and / or protruding receiving areas, for the connection to a base element or the component. The four side surfaces of the foundation

[0116] REVISED SHEET (RULE 91) ISA / EP components may each have at least one undercut.

[0117] The undercut of the foundation element can extend from the top side of the foundation element to a bottom side of the foundation element. In particular, the undercut extends perpendicular to the foundation element in the installed position. The undercut can have a substantially constant cross-sectional area over the entire extent of the undercut.

[0118] The foundation element can be closed on at least one side adjacent to the underside. Thus, the foundation formed from a plurality of foundation elements can be closed to the outside, allowing it to be filled with fill material.

[0119] The cavity may have at least one lateral opening on one side adjacent to the bottom, allowing a connection to the cavities of adjacent foundation elements. Such a connection has the advantage that filling material such as concrete can be poured into one cavity and also distributed into the other cavities of other foundation elements.

[0120] The system may comprise a closure element for closing at least one lateral opening of the foundation component

[0121] Preferably, the foundation component can have lateral openings on two, three or four sides adjacent to the underside in the installed position to the cavity of the foundation component.

[0122] REVISED SHEET (RULE 91) ISA / EP Alternatively or additionally, the system may comprise a foundation connector for connecting two foundation elements by engaging the undercuts.

[0123] The at least one lateral opening of the foundation component can be at least partially formed by the undercut.

[0124] The closure element can be inserted into the lateral opening, in particular into the undercut, perpendicular to the surface of the foundation component in the installed position of the foundation component. The closure element can be shaped complementarily to the undercut, so that the closure element can close a lateral opening when the closure element is inserted vertically into the undercut in the installed position of the foundation component. A length of the closure element preferably corresponds at least to an extent of the undercut or at least to the lateral opening if this is formed by only a part of the undercut.

[0125] The closure element allows the size of a foundation, which is created using a variety of foundation elements, to be adjusted. Furthermore, a user does not have to use foundation elements with different numbers of side openings to enclose a foundation area for filling; instead, all foundation elements can have more than three, and in particular four, side openings.

[0126] The system comprising the foundation component can comprise two foundation components. The foundation connecting element can be designed for essentially form-fitting attachment in two undercuts of two foundation components in order to connect them together. The foundation connecting element preferably does not extend along the entire height of the foundation component.

[0127] REVISED SHEET (RULE 91) ISA / EP elements in the installed position. Thus, a lateral opening formed by only a portion of the undercut can remain open even though the foundation connecting element has been inserted.

[0128] The foundation connecting element can be shaped to correspond to two adjacent undercuts of two foundation components.

[0129] In the installed position, a passage of the foundation component can extend from the top through the receiving areas to the bottom of the foundation component.

[0130] The system may comprise an intermediate floor element. In an installed position, the intermediate floor element has at least one attachment area on each of its four vertical side surfaces for attachment to the receiving structure of a component. The attachment area may also be designed for attachment to an adjacent attachment area.

[0131] The intermediate floor element can have a cavity for pipes, in particular for underfloor heating. Alternatively, a separate intermediate floor support element can have such a cavity.

[0132] The intermediate floor element and / or the intermediate floor support element can run continuously from one wall side formed by building elements to an opposite wall side.

[0133] The intermediate floor elements and intermediate floor support elements can be arranged at an angle relative to one another in a horizontal plane, in particular at a right angle. This arrangement increases the stability of the intermediate floor.

[0134] The intermediate floor element and / or intermediate floor support element can be mounted on the formwork elements and / or wall panels of the system.

[0135] REVISED SHEET (RULE 91) ISA / EP tems attached to the structural elements of a wall. Thus, the intermediate floor element and / or the intermediate floor support element can be supported by the sheathing elements and / or wall panels.

[0136] The system may comprise a base element. The base element may have, in an installed position on a bottom side, at least one connecting element that is shaped complementarily to the at least one protruding or depressed region of the foundation component.

[0137] On the upper side of the base element in an installed position, the base element can have at least one recess and a substantially horizontal surface. The recess can be suitable for receiving a building element or a floor covering element.

[0138] Alternatively, the base element may have at least one protruding portion on the top side.

[0139] The protruding or depressed area can be arranged in an installation position vertically above the connecting element of the base element.

[0140] The depressed area or the protruding area may be shaped complementarily to a male connecting element or female connecting element of the component.

[0141] The base element may comprise two, four, six, or eight protruding or depressed regions. The protruding and / or depressed regions may be arranged mirror-symmetrically on the base element along one axis, preferably two axes.

[0142] REVISED SHEET (RULE 91) ISA / EP The top surface of the base element can accommodate at least one flooring element, which preferably has the same periphery as part or all of the top surface of the base element. The flooring elements can also have multiples of the periphery of the base element, thus reducing the labor required for installation.

[0143] A vertically extending side surface of the base element in the installed position can have an upwardly extending and protruding portion. Two protruding portions can be arranged on opposite sides of the base element. This protruding portion can be fixed by a wall panel or a gable element.

[0144] The base element may have a passage extending from the top side of the base element to the bottom side of the base element. The passage may extend through the upwardly projecting or depressed area on the top side and, in particular, through the connecting element located on the bottom side.

[0145] The passages of the structural element, the foundation structural element, and in particular the base element of the system can be arranged directly above one another in the respective installation position to form a continuous cavity. The elongated reinforcement can be arranged in the passage of the structural element, the foundation structural element, and / or the base element, in particular in the entire continuous cavity.

[0146] The system may also include the elongated reinforcement. The elongated reinforcement may be insertable into at least two of the passages of components stacked one above the other in the installed position. The elongated reinforcement may have a length of at least

[0147] REVISED SHEET (RULE 91) ISA / EP at least 1 m, in particular at least 1.5 m, preferably at least 2 m.

[0148] This allows the reinforcement to stabilize the wall and preferably to be anchored in the ground and / or the filler-cast foundation.

[0149] The reinforcement may have a channel along a longitudinal extent of the reinforcement, preferably extending over the entire length of the reinforcement and preferably having two openings at two longitudinal ends of the reinforcement. This allows for material savings and also allows for the installation of water pipes, electrical wires, or radiators within the reinforcement.

[0150] An alternative embodiment of the structural element can, in one installed position, have two of the previously described receiving structures on the two opposite vertical side surfaces. On the other two opposite vertical side surfaces of the structural element, however, the structural element has connecting areas that are designed analogously to the connecting areas of the wall panel. Otherwise, such a structural element is shaped as described above. Such a structural element allows the formwork elements to be attached directly to the structural element without a wall panel.

[0151] At least one side surface of the component in an installed position can have a downwardly or upwardly extending projection. Such a projection can strengthen the connection between components mounted one above the other. The projection can extend continuously or partially between two opposite side surfaces of the component.

[0152] REVISED SHEET (RULE 91) ISA / EP The previously described components and elements of the systems may each have a base area which is an integer subset of 120 x 80 cm 2 or an integer multiple of 120 x 80 cm 2 This has the advantage that the components and elements can be easily transported on pallets of this size.

[0173] Figures 1A and 1B show perspective views of an embodiment of a component 101 from below and from above. The component 101 has two female connecting elements 7 on the underside 5 and two male connecting elements 6 on the top side 4, which are arranged one above the other in an installation position 11 essentially on a vertical axis V. In addition, the male and female connecting elements 6, 7 are arranged centrally between two opposite side surfaces 22, 24. The component 101 in the installation position 11 is twice as wide as it is deep and the connecting elements 6, 7 are arranged exactly centrally in one half of the component 101 with a square base area. The width B of the component 101 is 40 cm, the height 20 cm and the depth D also 20 cm. The height of the component 101 in the installation position 11 including the male connecting element 6 is 30 cm.

[0174] A passage 8 extends through the upper male connecting element 6 in the vertical direction and merges into the opening of the female connecting element 7 on the underside 5. The female connecting element 7 and male connecting element 6 are cuboid-shaped, so that the male connecting element 6 of the component 101 can be inserted in a form-fitting and rotationally secure manner into the female connecting element 7 of a component 101 located above. On the two lateral side surfaces 21, 23, a receiving structure 3 is arranged in each case, and on the end-facing side surfaces 22, 24

[0175] REVISED SHEET (RULE 91) ISA / EP, two receiving structures 3 are arranged in each case. A receiving structure 3 comprises two recesses 31, 32 between which a depression 37 is arranged. The longitudinal axes of the recesses 31, 32 and the depression 37 run parallel to one another in the vertical direction of the component 101 in the installation position 11 and extend over the entire side surfaces 21, 22, 23, 24. The cross section of the recesses 31, 32 is the same along the entire vertical axis and has an undercut (see Figs. 3A to 3H). The depression 37, on the other hand, has a substantially constant rectangular cross-sectional shape along its entire longitudinal axis.

[0176] The upper side 4 of the component 101 has a step 41 that extends circumferentially along the edge between the upper side 4 and the side surfaces 21, 22, 23, 24. The step 41 forms a partially enclosed cuboid-shaped cavity when two components 101 are arranged one above the other. The step 41 connects the recesses 31, 32 and depressions 37 of the receiving structure 3. Thus, the step 41 can be used for laying electrical or water lines, particularly in the horizontal direction in the installation position 11.

[0177] Figures 2A to 20 show three alternative embodiments of a cube-shaped component 102 in a perspective view. A cube-shaped shape of the components 102 allows, in combination with components twice as wide (see Fig. 1A and Fig. 1B), the components to be arranged one above the other in rows offset relative to one another (see Fig. 11). The component in Fig. 2A has a hollow cylindrical male connecting element 61, so that several components 102 can be arranged one above the other in a rotatably connected manner. The components 102 in Fig. 2B and Fig. 20, on the other hand, have a prism-shaped male connecting element 62. In Fig. 2B

[0178] REVISED SHEET (RULE 91) ISA / EP the male connecting element 62 has a hexagonal base area and in Fig. 2C a square base area. The components 102 according to Fig. 2B and Fig. 2C can thus be connected in a rotationally secure manner on the top side 4 and bottom side 5 to other components 102 in an installation position 101. The longitudinal axis of a passage 8 is aligned exactly centrally in the component 102 and runs in the vertical direction V in the installation position 11. The same receiving structure 3 is arranged on all side surfaces 21, 22, 23, 24 so that no errors in the alignment of the components 102 can occur when the components 102 are arranged. Each receiving structure 3 in Fig. 2A and Fig. 2B comprises two cutouts 31, 32 and a depression 37. The receiving structure 3 of the component 102 of Fig .2C, on the other hand, has only one recess 31, which has a trapezoidal base area, so that a dovetail-shaped connecting element can be attached (see Figs. 4C and 4D). Furthermore, the recess 37 in Fig. 20 runs in the region of two adjacent side surfaces 21, 22, 23, 24 from the top side 4 to the bottom side 5 and has a cross-sectional area of ​​2 cm x 2 cm.

[0179] The width B of the component 102 in Fig. 2A to 2C is 20 cm, the height 20 cm, and the depth D also 20 cm. The height of the component 102 in the installation position 11, including the male connecting element 61, 62, is 30 cm.

[0180] Figure 2D shows a perspective view of a fourth embodiment of the component 101 connected to a connection element 9 from Fig. 4C and 4D in a receiving structure 3 of the component 101. For previously described components of the component 101, reference is made to Fig. 2C. The component 101 in Fig. 2D has twice the width of the component of Fig. 2A to 20, 40 cm. On the two long sides 22, 24 of the component 101, two receiving structures 3 are attached next to each other and on the shorter sides 21, 23, a receiving

[0181] REVISED SHEET (RULE 91) ISA / EP structure 3 . A connecting element 9 is attached to the receiving structure 3 of the right-hand short side 23 . The connecting element 9 is essentially T-shaped and has a connecting bar 311 with two lateral, dovetail-shaped widenings 3111 (see Figs. 4G and 4D). By inserting the connecting bar 311 into the two recesses 31 with a trapezoidal base area of ​​adjacent components 101 , the components 101 can be connected to one another. A head region 93 of the connecting element 9 is half arranged in a respective step 41 of the components. The shape of the head region 93 of the connecting element 9, however, leaves the step 41 of the adjacent side surfaces 22 , 24 free. Thus, a cable can be guided horizontally to the side surfaces 22, 24 within the step.

[0182] Figures 3A to 3H show cross sections of various embodiments of recesses 32 of a component, such as according to Fig. 1A to Fig. 2B. All recesses 32 have an undercut 33 with a greater extent 35 than the extent 36 in an opening region 33. The cross section can be L-shaped as in Fig. 3A or T-shaped as in Fig. 3B. In addition, the cross section can comprise rounded regions as in Fig. 3C to Fig. 3F, so that the pressure from inserted connection elements, in particular connecting bars, can be distributed more evenly and no load peaks in the material arise. The recess 32 in Fig. 3G and Fig. 3H is dovetail-shaped. In all embodiments Fig. 3A to Fig. 3H, a connecting element can be inserted in the longitudinal direction of the recess 32 in a substantially form-fitting manner.For this purpose, two recesses 32 of two adjacent components are arranged such that the side surfaces 22 abut one another and the recesses 32 form a connected cavity. The components can then be fixed relative to one another by

[0183] REVISED SHEET (RULE 91) ISA / EP the connecting element is inserted into the cavity formed by the recesses 32.

[0184] Figures 4A and 4B show perspective views of a first embodiment of a connecting element 9 from below and from above. The connecting element 9 has, in an installed position 95, a head region 93 which comprises lateral flanges 941, 942 which have a wider extent 96 than a central web 92 of the head region 93. The head region 93 of the connecting element 9 thus forms, in an installed position 95, a double-T profile 91 in a horizontal plane. By means of such a double-T profile 91, the connecting element 9 can be inserted essentially in a form-fitting manner into a step on the upper side of a component (see Figures 5A and 5B), such that the step prevents the connecting element 9 from tilting relative to the component.

[0185] In the installation position 95, the head region 93 is materially connected to the laterally outer region of the flanges 941, 942 by a first connecting bar 311 and a second connecting bar 321. A central bar 371 for connecting the recesses is arranged between the first connecting bar 311 and the second connecting bar 321. The connecting bars 311, 321, 371 run parallel and are not connected to one another on the side opposite the head region 93. The connecting bars 311, 321, 371 can therefore be inserted together from above into the recesses of two adjacent components in the installation position 95 by means of a single translational movement. Fig. 4A also shows that the first and second connecting bars 311, 321 are C-shaped in cross section and the open sides 312, 322 of the C-shaped connecting bars 311, 321 are aligned with each other.By such an inwardly directed shape 312, 322 of the recesses 311, 321, the recesses 311, 321 can be placed laterally far apart.

[0186] REVISED SHEET (RULE 91) ISA / EP so that the fixation with a connecting element 9 can be improved. Two C-shaped connecting bars 311, 321 make the connection between the components more flexible. Even after damage / defect to the connecting bars 311, 321, a connection between two components can still be ensured by the other connecting bar 311, 321.

[0187] Figures 4C and 4D show perspective views of a second embodiment of a connecting element 9 from below and from above. The connecting element 9 has, in an installed position 95, a head region 93 which has a constant extension 96. The connecting element 9 also has a central connecting bar 311. The connecting bar 311 has, in relation to the lateral side surfaces 98, 99, two opposite dovetail-shaped widenings 3111. The connecting bar 311 of the connecting element 9 can fix the two components relative to one another by a translational movement into the recesses of two adjacently arranged components with trapezoidal recesses (Fig. 2C or Fig. 2D). The connecting bar 311 has a shape which is essentially congruent with the trapezoidal recesses with undercut of the components.Such a dovetail-shaped connecting bar 311 makes the connection between two components more stable and rigid.

[0188] Figure 5A shows a perspective view of an embodiment of a component 102 with a step 41, highlighted by a dotted area. The step 41 extends in an installation position 11 of the component from an upper end of a first recess 31 over the upper end of a depression 37 to the upper end of a second recess 32 of the receiving structure 3. All side surfaces 21, 22, 23, 24 have identical receiving structures 3 with recesses 31, 32 and the depression 37.

[0189] REVISED SHEET (RULE 91) ISA / EP on , at the upper end of which the step 41 of the upper side 4 is arranged in an installation position 11 .

[0190] Figure 5B shows a perspective view of an embodiment of the component 102 according to Fig. 5A with a connection element 9 inserted into the receiving structure 3 in the longitudinal section LS (see Fig. 4B). The longitudinal section LS runs exactly centrally through the connection element 9 parallel to the side surface 22. One half of a head region 93 of the connection element 9 with a double-T profile 91 is marked with dots in Fig. 5B for better visibility. The head region 93 of the connection element 9 fills the step between a side 22 and the top side 4 of the component in a form-fitting manner (see Fig. 5A). The connection element 9 also has connecting bars 311, 321, 371, which are also fixed in a form-fitting manner in the recesses 321, 322 and a depression 37.In the connected state of two components 102, the recesses 32, 32 and the depression 37 are arranged adjacent to the recesses 32, 32 and the depression 37 of the connected component 102. The height H, width B, and depth D have the same dimensions as in Figs. 2A and 2B.

[0191] Figures 6A and 6B show a foundation component 17 in a perspective view from below and from above. The foundation component 17 has a cavity 179 on a bottom side 1712, which is suitable for receiving fillers such as cement or reinforcement such as steel struts. In addition, the cavity 179 of the foundation component 17 is suitable for receiving pipes, in particular water pipes of an underfloor heating system. The cavity 179 has an opening 1791 on all side surfaces 173, 174, 175, 176 of the foundation component 17. The openings 1791 are arranged centrally on the side surfaces 173, 174, 175, 176, so that the cavities 179 of adjacent foundation components 17 can be connected to one another. On the top side

[0192] REVISED SHEET (RULE 91) ISA / EP 1711, the foundation element 17 also has a passage 1792 that is connected to the cavity 179. Thus, after proper installation, the foundation element 17 can be filled from above, for example with cement, through the passage 1792.

[0193] In an alternative embodiment, the cavity 179 can also be closed at the bottom in an installation position 171 of the foundation component. Furthermore, the foundation component 17 has female connecting elements 178 or male connecting elements 177 on the edges of the upper side 1711 and the side surfaces 173, 174, 175, 176.

[0194] In Fig. 6A and Fig. 6B, a pair of male or female connecting elements 177, 178 are each arranged on a side surface 173, 174, 175, 176. The male and female connecting elements 177, 178 run from the top side only over a partial area of ​​the side surfaces 173, 174, 175, 176 and not all the way to the bottom side 1712. Thus, adjacent foundation components 17 in the installation position 171 can be connected to one another by the complementary female and male connecting elements 177, 178 just by slightly lifting one of the foundation components 17. The upper side 1711 also has four lowered receiving areas 172 so that a base element can be attached for connection to a floor covering element or building element (see Figs. 9 and 10).The lowered receiving areas 172 are arranged on the foundation component 172 such that the receiving areas 172 of several connected foundation components 17 are equidistant from one another. Thus, for example, components (see Figs. 1A and 1B) can be attached to two receiving areas on one foundation component 17 or to two adjacent foundation components 17. The foundation component 17 has a height of 30 cm, a depth of 40 cm, and a width of 17 cm.

[0195] REVISED SHEET (RULE 91) ISA / EP of 40 cm. This size provides an ideal weight for installing the foundation components 17, as they are easy to lift and yet cover a large area. The base area in Fig. 6A and 6B is thus exactly twice as large as the base area of ​​a component in Fig. 1A, 1B, or 2D. Due to the large cavity 179, the foundation components 17 are nevertheless easy to lift for placement.

[0196] Figures 6C and 6D show a perspective view from below and from above of an embodiment of the foundation component 170. The foundation component 170 has four side surfaces 1703, 1704, 1705, 1706, each having two undercuts 1707. The undercuts 1707 extend vertically in an installation position 1701 (see Fig. 6D) from an upper side 17011 to a lower side 17012 of the foundation component 170. The foundation component 170 also has four receiving areas 1702 on the upper side 17011, which can be connected to a base element 18 (see Figs. 9A-10B). The receiving areas 1702 can also alternatively form passages for receiving reinforcements 20 (see Fig. 15).

[0197] Figure 6C shows that the foundation component 170 forms an open cavity 1709 on the underside 17012, which is connected to lateral openings, each of which is partially formed by the undercuts 1707. Thus, the cavity 1709 can be connected to adjacent cavities of other foundation components 170, so that, for example, a foundation made of filler materials such as cement can be poured. The foundation component 170 also has a passage 1710 on the upper side 17011, so that the foundation component 170 can be filled from above in the installed position 1701.

[0198] REVISED SHEET (RULE 91) ISA / EP To prevent the filler from escaping, for example, at the edge of the planned foundation, a closure element 1708 can close the lateral opening in the form of the undercut (see Fig. 6C). Adjacent foundation elements 170 can also be connected with a foundation connecting element 90, which can be inserted in a form-fitting manner into the undercuts 1707 of adjacent foundation elements 170 (see Fig. 6F).

[0199] Figure 6E shows a perspective view of an embodiment of a closure element 1708 for closing a lateral opening of an embodiment of the foundation component 170 according to Figs. 6C and 6D. A cross-sectional area of ​​the closure element 1708 is essentially isosceles trapezoidal and is constant over an entire longitudinal extent L of the closure element 1708. This enables the closure element 1708 to be easily inserted into the undercut 1707 (see Figs. 6C and 6D) in order to close the cavity 1709 located behind it, so that no filler can escape during filling.

[0200] Figure 6F shows a perspective view of an embodiment of a foundation connecting element 90 for the positive connection of two foundation components 170 according to Figs. 6C and 6D. A cross-sectional area of ​​the foundation connecting element 90 is constant along a longitudinal extent L of the foundation connecting element 90. The cross-sectional area is formed by two isosceles trapezoids that are connected to one another at their short side (see dashed line). In addition, the foundation connecting element 90 has a projection 100 in an upper region in an installed position, which projection is designed to correspond to a recess in the foundation component 170 (see Figs. 6C and 6D).

[0201] CORRECTED SHEET (RULE 91) ISA / EP Figures 7A and 7B show two perspective views of a first and a second embodiment of a wall panel 12 which is connected to a formwork element 15. The wall panel 12 in Fig. 7A has a plurality of first L-shaped connecting regions 131 on a first side surface 13. The open sides of the L-shaped connecting regions 131 face one another in pairs, so that an intermediate space 121 is partially enclosed. On the first side surface 13, three such L-shaped connecting regions 131 are arranged in pairs in two adjacent rows 133, 134.

[0202] On an opposite second side surface 14 of the wall panel 12 in Fig. 7A and Fig. 7B, second L-shaped connecting regions 141 are arranged. The second L-shaped connecting regions 141 extend over a large part (see Fig. 7B) or the entire second side surface 14 (see Fig. 7A) and run orthogonally to the first connecting regions 131. In an installed position of the wall panel 12, the first connecting regions 131 are aligned with their longitudinal axis vertically and the second connecting regions 141 are aligned with their longitudinal axis horizontally. The wall panel 12 also has a plurality of stepped regions 122 so that adjacent wall panels 12 touch each other over a larger area and thus seal and insulate better. A separate seal on the stepped regions 122 would also be conceivable.

[0203] The first L-shaped connecting areas 131 can be inserted into the recesses 31, 32 with an undercut of the receiving structure 3 of the component (see Fig. 1A and 1B) in a form-fitting manner in order to be connected to a side surface of the component. The recesses of components arranged one above the other adjoin one another at the sides, so that the wall panel 12 with the first connecting area 131 along the

[0204] REVISED SHEET (RULE 91) ISA / EP recesses of several components in one mounting position can be inserted from above.

[0205] A first row 133 of the connecting regions 131 of the wall panel 12 can be connected to a first component, and a second row 134 of the connecting regions 131 of the wall panel 12 can be connected to a second component. This reduces the amount of work required to attach the wall panels, as a larger area can be attached in a single step. However, the central recess (see, for example, Figs. 1A and 1B, 37) is left free when attaching the wall panel according to Fig. 7A, so that a cable can be routed therein (see Fig. 8).

[0206] In a second embodiment of a wall panel 12 in Fig. 7B, the first connecting regions 132 are dovetail-shaped on an upper side 13. The dovetail-shaped connecting regions 132 can thus be inserted into an undercut of the recess (see Figs. 2C and 2D, 31) with a trapezoidal base in a substantially form-fitting manner. On the upper side 13, two connecting regions 132 are arranged side by side in two rows 133, 134.

[0207] The second L-shaped connecting regions 141 in Figs. 7A and 7B are shaped to positively receive an L-shaped receiving region 151 of the formwork element 15. For this purpose, the receiving region 151 is shaped complementarily to the second connecting region 141. In an installed position of the wall panel 12, an opening of the L-shaped second connecting region 141 preferably points upwards, so that the receiving regions 151 of the formwork element 15 can be inserted from above.

[0208] An outer side 16 of the formwork element 15 is essentially aligned, so that adjacently mounted

[0209] REVISED SHEET (RULE 91) ISA / EP Shuttering elements 15 form a substantially continuous and flush surface .

[0210] Figure 7C shows a perspective top view of a third embodiment of a wall panel 12 which is attached to a building element 101 according to Figs. 1A and 1B. The wall panel 12 in Fig. 7C has an aligned first side surface 13 and a second side surface 14 with two L-shaped connecting regions 141. The two L-shaped connecting elements 141 are inserted into recesses 31, 32 of the building element 101 from an upper side 4 of the building element 101 in a substantially form-fitting manner, so that the wall panel 12 is fixed to the building element 101. In addition, the wall panel 12 has a stepped region 122 for enlarging the contact area to adjacent wall panels 12. However, a recess 37 measuring 2 cm x 2 cm in the structural element 101 remains free despite the wall panel 12 being attached. Thus, an electrical or water line can be installed or run through the recess 37.The components 101 are shaped such that the recesses 37 on a side surface 24 of stacked components 101 adjoin one another in an installed position in order to guide vertically extending lines. Furthermore, the L-shaped connecting regions in Fig. 70 do not extend over the entire side surface 14, so that a step 41 of the component 101 remains free. This allows the lines to also be guided horizontally along the step 41 in the installed position of the component.

[0211] Figure 8 shows a perspective view of a first embodiment of a corner formwork element 152 with two connecting areas 153 on each inwardly facing side surface 157, 158. The connecting areas 153 are each connected to the L-shaped connecting areas of the wall panels (see Fig. 7A,

[0212] CORRECTED SHEET (RULE 91) ISA / EP 141 ) can be connected to two side surfaces of a building element that are arranged next to one another and orthogonally. The connecting areas 153 run horizontally so that the L-shaped opening can be aligned downwards. The corner cladding element 152 can therefore be inserted vertically from above into the connecting areas of the wall panel. Such a corner cladding element 152 has two flat surfaces which are formed by two outer surfaces 155, 156 of the corner cladding element 152. The outer surfaces 155, 156 form an angle of 270 ° to one another in Fig. 8. The inner surfaces 157, 158, on the other hand, form an angle W of 90 ° to one another in Fig. 8. Thus, the corner formwork element 152 can be attached to an outer corner with adjacent sides at 270 ° to each other of a building element system.

[0213] Analogous to this embodiment of the corner cladding element 152, the connecting areas 153 can also be arranged on the outer surfaces 155, 156 in a second embodiment to form a corner by two aligned inner surfaces 157, 158 of 90 degrees (not shown in the figures). Thus, the corner cladding element can be attached to an inner corner with adjacent sides at 90° to each other.

[0214] Figures 9A and 9B show a perspective view of a first and second embodiment of a base element 18 for connecting a building element 101 (see Figs. 1A and 1B or Figs. 20 and 2D) and a foundation element 17, 170 (see Figs. 6A to 6D). The base element 18 has on an upper side 183 in an installation position 181 a protruding cuboid region 185 which is shaped for a positive connection with a female connecting element 7 (see Fig. 1A) of the building element. On an underside 182 of the base element 18 in the installation position 181, the base element 18 has two cuboid male connecting elements 184. The male connecting

[0215] REVISED SHEET (RULE 91) ISA / EP The connecting elements 184 are shaped complementarily to the depressed areas 172, 1702 (see Fig. 6B or Fig. 6D) of a foundation element 17, 170 in Figs. 6A - 6D. Furthermore, the base element 18 in Figs. 9A and 9B has dovetail-shaped connecting elements 1811, 1812 on all four side surfaces 186, 187, 188, 189.

[0216] Figure 9A shows that a female dovetail-shaped connecting element 1812 is arranged on each of the two front side surfaces 186, 187, and a male dovetail-shaped connecting element 1811 is arranged on each of the rear side surfaces 188, 189. Thus, horizontally adjacent base elements 18 can be connected to one another by the dovetail-shaped connecting elements 1811, 1812 in Fig. 9A.

[0217] Figure 9B shows that a female dovetail-shaped connecting element 1812 is arranged on each of the side surfaces 186, 187, 188, 189. The female connecting elements 1812 can be connected to each other by base connecting elements that are shaped similarly to the foundation connecting elements 90 (see Fig. 6F).

[0218] In addition, the base element 18 in Figs. 9A and 9B has a passage 1813 which, when properly installed, is adjacent to the passage (see e.g. Fig. 1B, 8) of the components.

[0219] Figures 10A and 10B show a perspective view of a third and fourth embodiment of a base element 19 for connecting a floor covering element, in particular parquet, and a foundation component (see Figs. 6A and 6B). In contrast to Figs. 9A and 9B, the base element 19 has a connecting element 194 in the form of a

[0220] REVISED SHEET (RULE 91) ISA / EP countersunk cuboid-shaped portion 194. The countersunk portion 195 is shaped to complement the receiving portion of a flooring element (not shown in the figures). The countersunk portion 195 may also be shaped to complement the receiving portion of a male connecting element 6 of the building element (see Figs. 1A and 1B).

[0221] The dovetail-shaped connecting elements 1911, 1912 in Fig. 10A on the side surfaces 196, 197, 198, 199 of the base element 19 and the male connecting element 194 are shaped analogously to Fig. 9A.

[0222] The dovetail-shaped connecting elements 1912 in Fig. 10B on the side surfaces 196, 197, 198, 199 of the base element 19 and the male connecting element 194 are shaped analogously to Fig. 9B.

[0223] A base area of ​​the base element 18, 19 in Fig. 9A to Fig. 10B is 40 cm x 20 cm, so that two base elements 18, 19 can be arranged on the foundation element to completely cover it.

[0224] Figure 11 shows a schematic, perspective view of a system 1 with several components 101, 102, which are arranged partially offset from one another to increase stability. Stability can be further increased, for example, by guiding steel struts through adjacent passages 8 (see Figs. 1A and 1B) through several superimposed components 101, 102. For greater clarity, the depiction of the receiving structures 3 and connecting elements 6, 7 (see Figs. 1A and 1B) of the components 101, 102 has been omitted in Fig. 11.

[0225] REVISED SHEET (RULE 91) ISA / EP System 1 in Fig. 11 comprises both essentially cuboid-shaped components 102 with a base area of ​​20 cm x 20 cm and cuboid-shaped components 102 with a base area of ​​20 cm x 40 cm. The height of the components 101, 102 is 30 cm.

[0226] Figures 12A and 12B show a perspective view of a first and second embodiment of a system 1 comprising a building element 101, a foundation element 17, a base element 18, a connecting element 9, a wall panel 12, and a formwork element 15. On half the base area of ​​the foundation element 17, the base element 18 is fixed by two male connecting elements 184 (see Fig. 10) on the underside in countersunk and cuboid-shaped regions 172 of the foundation building element 17. On the top side of the base element 18, the base element 18 is connected to the female connecting elements 7 (see Fig. 1A) by inserted cuboid-shaped regions 185 (see Fig. 10). The base element 18 and the building element 101 have the same base area of ​​40 cm x 20 cm.

[0227] On a front side 21 of the component 101 in Fig. 12A and 12B, a connection element 9 is half-sunk into a receiving structure 3 of the component 101, so that the head region 93 (see Fig. 4A - 4C) fills a step 41 (see Fig. 1B) of the component 101 on the front side 21. In Fig. 12A, the component 101 has a double L-shaped receiving structure according to Fig. 2A and 2B and in Fig. 12B a partially dovetail-shaped receiving structure according to Fig. 2C and 2D. In Fig. 12A, the connection element 9 has, analogous to Fig. 4A and 4B, two lateral connecting bars 311, 321 and a central bar 371 (see Fig. 4A and 4B). In Fig. 12B, however, the connecting element 9 has a dovetail-shaped central connecting bar 311 (see Fig. 4C and 4D). The wall panel in Fig. 12A has two, complementary to the receiving structure 3 of the

[0228] CORRECTED SHEET (RULE 91) ISA / EP component 101 formed, double-L-shaped first connection regions 131 analogous to Fig. 7A. In Fig. 12B, however, the first connection regions 131 are dovetail-shaped analogous to Fig. 7B and shaped complementarily to the receiving structure 3.

[0229] In Fig. 12A and 12B, the formwork elements 15 are inserted into the upwardly open second L-shaped connecting regions 141 in order to fasten the formwork elements 15 to the wall panel 12. In Fig. 12A and 12B, the wall panels 12 are twice as high as the building element 101 without a male connecting element 6 of the building element 101. Such wall panels 12 achieve an optimal weight of the wall panels 12 and also reduce the labor required for attaching them to the building elements 101. Since the receiving structure 3 of the building elements 101 extends vertically upward in the installed position, several receiving structures 3 can be connected to one another so that the wall panel 12 can be easily attached.

[0230] Figures 13A to 13C show a second and a third embodiment of a corner cladding element 152 with two adjacent connecting regions 153 which are at an angle to one another. In the second embodiment of the corner cladding element 152 in Fig. 13A, the connecting regions 153 are arranged in four rows one above the other on the inward-facing side surfaces 157, 158. In the third embodiment of the corner cladding element 152 in Fig. 13B and Fig. 13C, the connecting regions 153 are arranged in only two rows one above the other on the inward-facing side surfaces 157, 158. The connecting regions 153 can each be connected to the connecting regions 141 of the wall panels (see Fig. 7A) or directly to a building element (see Fig. 14). The connecting areas 153 have, analogously to Fig. 8, L-shaped openings which in an operating position

[0231] REVISED SHEET (RULE 91) ISA / EP can be aligned vertically downwards in order to be connected to the wall panels and / or building elements. The adjacent connecting areas 153 of the corner cladding element 152 are arranged at an angle W of 90° to one another. However, an embodiment of 270° would also be conceivable for cladding internal corners. Such an embodiment allows the corner cladding element 152 to be attached to an internal corner of a wall with adjacent sides at 90° to one another.

[0232] The corner cladding element 152 in Fig. 13A has four connecting regions 153 arranged one above the other, and the corner cladding element 152 in Fig. 13B and Fig. 13C has two connecting regions 153 arranged one above the other, so that the corner cladding element can be connected to a plurality of wall panels or building elements simultaneously. For this purpose, the four connecting regions 153 are rigidly connected to one another by an extended support 159. This reduces the labor required to attach the corner cladding element 153, and also achieves the most level cladding possible.

[0233] For better visibility of the connecting areas 153, an exemplary structured formwork 160 is shown in Fig. 13A only on one outer side 155. However, this formwork 160 is attached to the corner formwork element 152 on both outer sides 155 and 156 and is rigidly connected thereto.

[0234] Figures 14A and 14B show perspective views of two further alternative embodiments of a component 101 in an installation position 11. The component 101 differs from the component of Fig. 1A and 1B on the one hand by dovetail-shaped receiving structures 3, each with only one

[0235] REVISED SHEET (RULE 91) ISA / EP Recess 31 on the two front side surfaces 21, 23. In addition, the component 101 in Fig. 14A and Fig. 14B has upwardly open L-shaped receiving structures 38 on the two lateral side surfaces 22, 24. These L-shaped openings of the receiving structures 38 run horizontally in the installation position 11 and extend over an entire longitudinal length of the component 101. A formwork element 16 (see Figs. 7A and 7B) can be attached directly in these receiving structures 38 without the need for a wall panel 12 (see Fig. 7A). In addition, these receiving structures 38 also have a vertically running recess 37 with a rectangular cross-sectional area for guiding cables. A further difference between the embodiment of the component 101 in Fig. 14A and Fig. 14B and Fig.1A and 1B is that the component 101 has on each of the lateral side surfaces 22, 24 a downwardly projecting projection 39 and a receptacle 40 for this projection 39. This projection 39 extends over the entire longitudinal length of the component 101. The projection 39 is adapted to enclose a side surface 22, 24 of another component 101 located underneath in a substantially form-fitting manner and to be pushed into the receptacle 40. The projection 39 and the receptacle 40 enable more stable storage of components 101 arranged one above the other. A repeated description of the features already described above (see Fig. 1A, Fig. 1B, Fig. 5A and Fig. 5B) has been omitted in Figs. 14A and 14B.

[0236] The embodiment of the component 101 in the installation position 11 in Figure 14B differs from the embodiment in Fig. 14A by a horizontal recess 42, which is arranged on a lateral side surface 22 and extends partially through the component 101. This recess 42 is for receiving a steel beam as a support device for an intermediate floor

[0237] REVISED SHEET (RULE 91) ISA / EP adapted. Such structural elements 101 with horizontal recesses 42 on opposite wall sections can accommodate steel beams, so that a mezzanine floor can be supported by steel beams.

[0238] Figure 15 shows a perspective view of a wall formed by a plurality of structural elements 101 (see Fig. 2D), connecting elements 9 for connecting the structural elements 101, base elements 18 (see Figs. 9A - 9B), foundation structural elements 170 (see Figs. 6C and 6D) with closure elements 1708 (see Fig. 6E) and elongated reinforcements 20.

[0239] The side surfaces 1703, 1704 of the foundation component 170 are sealed by a plurality of closure elements 1708 so that the adjacent cavities 1709 can be filled with filler through the passages 1710 (see Figs. 6C and 6D).

[0240] In contrast to Fig. 60 and 6D, the foundation component 170 additionally has passages in the receiving areas 1702 so that the reinforcement 20 can be guided through the receiving elements.

[0241] The elongated reinforcement 20 is formed by a PVC or steel pipe that can be passed through the adjacent passages of the structural element 101, base element 18, and foundation structural element 170. This allows the reinforcement to be anchored in the soil and / or the filler-cast foundation.
