Description

The invention enters a transportable prefabricated composite wall element made of shuttering stones, in particular Holzspanschalungssteine, according to the preamble of claim 1 (see, for example FR-A-2743585 ).

For the erection of building walls formwork blocks are seamlessly set up in association and side by side, the formwork blocks have a cavity and can be processed by non-construction professionals due to the flat side surface and low weight. The masonry wall made of shuttering stones in this case has a cavity which extends in the vertical direction from the top stone row to the bottom stone row and can be filled with liquid concrete. This gives rise to the possibility of erecting a monolithic wall without formwork elements to be erected in a complicated manner.

In addition to the low weight and good processability with simple means, in particular wood puffing stones are still energy-saving and climate-friendly to produce. In a known manner, this wood is cut, mineralized and bound with cement. The formwork blocks known from the prior art are preferably rectangular and have a cavity in the vertical direction. In addition, recesses are provided on the front sides of the shuttering blocks, so that after the juxtaposition of individual rows of such stones to a building wall of extending in the vertical and horizontal direction cavity of the wall with liquid concrete can be filled.

In the DE 200 15 912 U1 is described in this context, a prefabricated wall element, which is made of Holzspanschalungssteinen. For the production of the wall element, the Holzspanschalungssteine be glued to each other and put side by side. Due to the low weight of Holzspanschalungssteine the wall element produced in this way is easily transportable and can therefore be prefabricated outside the construction site.

After transporting such a prefabricated wall element of Holzspanschalungssteinen on a construction site, this is placed on the intended location for the wall, wherein adjacent wall elements are aligned by means of mounting elements and connected to each other. After filling the cavities of the wall elements with concrete must be applied to the outer and inner wall surfaces in addition to the electrical, water and heating installation lines nor a thermal barrier coating and an exterior or interior wall plaster. This work is usually carried out in the traditional way by construction professionals, and this is quite costly due to the high cost of labor and travel, and the progress of this work depends on the weather conditions prevailing on the construction site. In addition, the quality and dimensional accuracy of the further processed on the site wall elements largely depends on the organization of the construction site and accordingly may vary.

Accordingly, it is an object of the present invention to provide an easily transportable, prefabricated building wall element, which facilitates the construction of a building, significantly reduces the construction time on the site and ensures a consistent quality of the building wall.

This object is achieved according to the invention by the features of claim 1.

Further features of the invention are contained in the subclaims.

According to the invention, a transportable prefabricated composite wall element comprises at least a first wall plate of stacked successive set and interconnected shuttering stones, in particular Holzspanschalungssteine which have cavities and recesses for continuous filling of the wall plate with liquid concrete. The side walls of the formwork blocks in this case form a first and second planar wall disk surface, wherein at least the first wall disk surface is connected to at least one plate-shaped module element, in particular an insulating or wall cladding element. To increase the flexural strength of the composite wall element of formwork blocks and module element extends, at least one bending and buckling stiff connection profile is provided, which at least partially along a lower or upper row of shuttering bricks, thereby connecting at least a part of the shuttering blocks with each other.

The connection profile prevents bending of the composite wall element transversely and perpendicular to the wall plane, as is the case, for example, in wall elements produced on the prior art on shuttering stones when lifting and filling the cavity with liquid concrete. The connecting profile, which preferably consists of a galvanized sheet metal, can in this case be screwed and / or glued to the shuttering blocks of the wall plate. In this case, the connection profile preferably has a U-shaped cross section with a straight web and in each case a flange arranged at right angles to the ends of the web, wherein the flanges embrace the lowermost or topmost row of formwork stones from the top or from the underside. In the area of the straight web of the U-shaped connecting profile openings for the flow of liquid concrete are provided through which the liquid concrete can be introduced into the cavity of the wall plate and can emerge again. By the escape of liquid concrete on the underside of the wall plate of the cavity of the wall plate, for example, with a foundation or ceiling plate on the site connectable.

In addition to a U-shaped cross section, it is of course also possible that the connecting profile has a rectangular, L- or T-shaped cross-section, wherein the L- or T-shaped cross section comprises at least two legs arranged at right angles to each other. The first leg is attached to the side walls of the formwork blocks, whereas the second leg extends along an upper or lower side of the shuttering blocks.

For the connection of the at least one module element with the wall plate, this may be glued to the wall disk surface, wherein only a thin layer of adhesive is required by the flatness of the wall disk surface formed by the side walls of the shuttering bricks. As an adhesive for connecting the formwork blocks to each other and formed from the side walls of the shuttering stone wall surface is preferably adapted to the material of the module element and the material of formwork blocks adhesive, for example, in a modular element of polyurethane or polystyrene foam a PUR foam used. In the production, the adhesive can with a Spray gun are applied to the adhesive surfaces of the shuttering blocks and the at least one module element. Due to the flatness of the wall disc surface there is also the advantage that when applying an exterior or interior wall plaster compensation of unevenness is eliminated, thereby reducing the amount of cleaning material compared to a conventionally produced wall.

In addition to bonding the at least one module element to at least the first wall disk surface, it may additionally or alternatively be provided for bonding that the at least one module element is connected via mechanical fastening means with the wall plate of formwork bricks. The mechanical connection of the at least one module element with the wall plate can be effected, for example, by means of concrete anchors, which extend into the cavity of the wall plate. The concrete anchor can for this purpose have at one end a self-tapping external thread which intersects a thread in the side wall of the shuttering stone into the cavity of the wall plate, whereby the at least one module element is fixed to the wall plate. On the other hand, however, it is also possible that a concrete anchor is inserted into the joint between two adjoining formwork blocks already when arranging the shuttering blocks in the dressing. For attachment of the at least one module element of the concrete anchor may have at its extending in the direction of the module element end an external thread that extends through the module element and which cooperates with a locking washer which has, for example, an internal thread that presses the module element against the wall plate ,

A mechanical connection of the at least one module element, which is provided as an additional attachment to an adhesive connection between the module element and wall plate surface, prevents release of the module element of the wall plate due to insufficient carrying capacity of the adhesive bond, which in particular module elements with a thickness greater than 20 cm , is possible with the occurrence of wind suction forces or as a result of age-related decrease in the adhesive force of the adhesive. In particular, when using a Holzweichfäserdämmelements as a module element, which has only a low tensile strength, resulting from the mechanical connection also has the advantage that tearing of the module element and thus a release of the module element is prevented by the wall plate.

The length and / or height of the at least one module element may substantially correspond to the height and / or the length of the wall panel of formwork blocks. However, according to one embodiment of the invention, the at least one module element can also have a greater height than the wall plate and extend beyond the last-arranged row of shuttering stones. The section of the at least one module element that extends beyond the wall plate can be advantageously used as a ceiling edge formwork for a ceiling panel to be produced on the construction site, which is arranged on the wall panel made of formwork blocks. This section of the at least one module element, which serves as ceiling edge formwork, preferably projects beyond the wall pane by approximately 18 to 25 cm.

Furthermore, at least two reveal plates are provided between the first and second wall plate, which close the open end faces of the first and second wall plate at least in sections. For this purpose, the reveal plate can be glued to the open end faces of the shuttering blocks of the first and second wall plate or mechanically connected. The soffit panels, each one Have smooth surface, in this case support the lintel with their upper edges from the bottom of the lintel ago.

In order to prevent bending of the composite wall element formed by the first and second wall plate and the impact element, the connection profile which connects the first and second wall plate with the camber element extends along the uppermost row of shuttering stones and the upper edge of the camber element. The connection profile can be screwed and / or glued, for example, with the shuttering blocks of the first and second wall plate and the lintel element.

According to the invention, the lintel element comprises a U-shaped shell body which is open at the top and consists of interconnected plate strips or glued together U-shaped formwork blocks, the latter preferably consisting of the same material as the shuttering blocks of the first and second wall plate. For the removal of wall, camber or ceiling loads, the lintel element further comprises a reinforcement which extends at least over the length of the lintel element and is fastened to at least one point on the shell body. The reinforcement is thereby enclosed by the inner sides of the scarf body, so that after filling the lintel element with liquid concrete, the reinforcement is arranged within the concrete. By attaching the reinforcement to the shell body, the bending stiffness of the bonded together from the plate strips or bonded together U-shaped formwork blocks scarf body is increased, so that the lintel does not bend when filling with liquid concrete. For example, a lattice girder can be used for the reinforcement of the lintel element, which can be produced in a large length and is cut to the appropriate size for the lintel element. The lattice girder preferably has a triangular or quadrangular cross-sectional shape, wherein one of the sides of the lattice girder is fastened by spacers to the side walls or the bottom wall of the shell body. When filling the lintel element with concrete, the forces acting on the U-shaped shuttering blocks or glued together strip strips are removed via the arranged on the side or bottom wall of the scarf body fasteners, the spacers and the lattice girder, whereby bending of the lintel element is avoided.

Furthermore, it can be provided according to the invention that on one of the outer sides of the lintel element, a plate-shaped member is fixed, which preferably has the same thickness as the module attached to the wall panels and consists of the same material.

According to the invention, it can further be provided that a parapet element is arranged between the first and the second wall disk. Like the first and second wall plate, the parapet element also consists of juxtaposed and / or superimposed rows of formwork blocks whose respective cavities form a cavity extending in the vertical and horizontal directions and whose outer sides form a first and second parapet surface on which the at least one Module element can be fastened. Preferably, the same type of shuttering blocks and a modular element of the same material and the same thickness as the modular element of the first and second wall plate are used for the preparation of the parapet element. The parapet member preferably has a width corresponding to the length of the lintel member and the mounting dimensions of a window member disposed in the opening bounded by the parapet member, the end faces of the first and second wall discs and the lintel member. The end faces of the parapet orienter are connected to the end faces of the first and second wall plate, which face the parapet element, in particular adhesively bonded. In the region of the impact of the end faces of the parapet element with the end faces of the first and second wall plate, no reveal plate is provided, so that the cavity formed by the formwork blocks of the parapet element forms a common cavity with the cavities of the first and second wall plates. Furthermore, along the bottom row of shuttering blocks of the first and second wall discs and the sill member, the connection profile which connects the first and second wall discs to the sill member extends. As described above, the connection profile can thereby be glued, screwed or nailed to the shuttering blocks of the first and second wall plate and the parapet element.

By connecting the first and second wall plate with the parapet element and the lintel element on the connection profile, there is the possibility that a transportable prefabricated composite wall element with integrated window and / or Door elements is provided, in which no twists and deformations occur during transport to the site, which can destroy the only small compressive stresses receiving glass surfaces of the window and / or door element.

Preferably, a soffit plate with a smooth surface is arranged on the uppermost row of shuttering stones of the sill element, which at least partially closes the cavity of the sill element upwards. Like the soffit plates at the open end faces of the first and second wall discs, this soffit plate also has a smooth surface, thus facilitating the attachment of sealing bands required for installation of a window member. In order to facilitate introduction of liquid concrete into the cavity of the parapet element, the reveal plate may be provided with openings through which the liquid concrete can be introduced into the cavity of the parapet element. In this way, the introduction of liquid concrete in the cavity of the parapet element takes place both on the open end faces of the first and second wall plate as well as on the disposed on the top row of formwork blocks of the parapet element soffit plate.

According to a further idea underlying the invention, it may be provided that the lintel element and the reveal panels or the lintel element, the reveal panels and the parapet element form an inherently rigid frame, which is arranged between the first and the second wall plate and encloses a window or door element , The inherently rigid frame with the integrated window or door element can be prefabricated as a separate component. During the placement of the prefabricated frame between the first and second wall plate, this has a rigidity, so that the frame does not deform in this case. As a result, damage to the glass surfaces of the window or door elements, which in particular sensitive to compressive stresses, avoided. In this way, a transportable composite wall element is provided whose items have a high degree of prefabrication.

Instead of a lintel or parapet element, it can be provided according to a further embodiment of the invention that between the end faces of the first and second wall plate a duct for receiving domestic installation line is arranged, which extends over the height of the first wall plate.

The duct is supported by the connection profile, which connects the first and second wall disc with each other. In this case, the conduit shaft can be closed via an inspection cover assigned to the second wall disk surface and is closed on its side associated with the first wall disk surface. This results in a U-shaped conduit shaft, which consists for example of waterproof glued multi-ply wood panels and is connected on its the first wall disk surface associated side with the at least one module element. In this way, the at least one plate-shaped module element completely covers the first wall disk surface of the first and second wall disk and the closed side of the conduit shaft. At the end faces of the first and second wall plate of the U-shaped duct shaft is fixed with its side walls, in particular glued and nailed and thus closes the cavity of the first and second wall plate relative to the duct. Alternatively, the duct can be made of U-shaped glued together formwork blocks. The inspection cover closing the duct can be provided with a vapor barrier and a sound insulation mat, of which the latter insulates flow noises from water- or gas-carrying installation ducts. In order to avoid a cold bridge within the composite wall element according to the invention, it may be provided according to the invention that the free cavity of the duct is filled with thermal insulation material. On one of the inner walls of the duct additionally holding elements for fixing installation cables can be arranged.

In addition to an arrangement of building services installation cables within the duct, it is conceivable according to the invention that, for example, a cistern of a toilet is disposed within the duct, this has a corresponding width for this purpose.

According to a further embodiment of the invention, a box-shaped annular anchor beam is arranged on the top row of shuttering blocks, which has two side plates arranged parallel to each other, which are at least partially connected to each other via a lower and upper U-shaped rail, wherein the side plates and the rails a reinforcement insert enclose. According to the invention, in each case at least one recess is provided in the U-shaped rail. The box-shaped annular anchor beam can in this case on the top row of formwork blocks of the first wall plate, on the top row of formwork bricks of the first and second wall plate or on the top row of formwork bricks of the first and second wall plate and be disposed on the top of the lintel element, wherein the openings provided in the rails for introducing liquid concrete into the annular anchor beam and the wall plate arranged underneath or the lintel element are provided. The liquid concrete can thus be introduced unhindered into the hollow space of the wall disk or the lintel element via the annular anchor beam. In the rail, which connects the side plates arranged parallel to each other, it is preferably a U-shaped galvanized metal rail, which are glued and / or nailed to the side plates, which are preferably wood cement fiber or multi-ply wood panels. By using a ring anchor bar arranged on the upper side of the composite wall element there is the advantage that in a building constructed from composite wall elements according to the invention, the bending and tensile forces can be introduced from adjacent walls or rafter roof constructions into the surrounding wall slices of the composite wall elements according to the invention, whereby a shear-resistant ceiling pane does not is required. The box-shaped annular anchor beam can be held, for example, by the section of the module element that extends beyond the wall disk.

According to the invention, it may further be provided that a plurality of plate-shaped module elements are mounted on at least the first wall pane surface. The plate-shaped module elements thereby form a common surface on which a reinforcing fabric is applied, which connects the plate-shaped module elements together. By the reinforcing fabric there is the advantage that the module elements are protected during transport and are connected to each other on the side of the wall plate as well as on the opposite side, resulting in an increased strength of the composite wall element. Advantageously, the reinforcing fabric is applied as a plaster layer on the common surface formed from the plate-shaped module elements.

For the integration of one or more installation lines in the composite wall element, it may be provided according to an advantageous embodiment of the invention that in the region of the first or second wall disc surface extending into the cavity of the wall plate opening is provided, which is closed by a sound plate. The Sounder plate has holes, which hold the at least one installation line and by the at least one installation line in the cavity of the wall plate on and executes. Within the cavity, the at least one installation line is surrounded by a jacket with sound insulation, which, after filling the cavity of the wall panel with concrete, insulates the flow noises which may occur during operation of the installation duct. The sheath also serves as protection of the installation line from the concrete. The carrying the at least one installation line sounding plate is preferably flush and seamlessly inserted into the cut opening of the wall plate, so that when filling of liquid concrete in the cavity of the wall plate, the wall disk surface is closed by the Abschallplatte and forms a flat wall disk surface together with the side walls of the shuttering stones. In the same way as on the side walls of the shuttering blocks can also be arranged on the Abschalplatte a module element, such as a plasterboard. The Abschalplatte is preferably glued in the cut opening of the wall plate and may additionally or alternatively be bolted or nailed to the side walls of the shuttering stones.

The arrangement of a Abschalplatte with an inserted into the cavity of the wall plate installation line has the advantage that after setting up the composite wall element as a building wall prying out of grooves in the wall for receiving installation cables is no longer necessary and the installation line in a simple way in the Inside of the wall plate is insertable.

According to a further embodiment of the invention, it may be provided that at least one further plate-shaped module element is also fastened on the second wall disk surface, wherein the module element is, for example, a cladding element, in particular a gypsum plasterboard or gypsum fiber board. By a two-sided arrangement of at least one module element on the wall disk surfaces of the wall plate of formwork bricks results in a composite wall element, which has a high rigidity before filling the cavity of the wall plate with concrete and only slightly distorted when filling with liquid concrete.

As an alternative to arranging at least one further plate-shaped module element on the second wall disk surface, according to the invention it can be provided that at least one installation plate element with at least one preassembled installation line arranged thereon is arranged on at least one section of the second wall disk surface. The installation plate element extends at least over a portion of the wall disk surface. However, if the wall disk surface does not have any projections or recesses, the installation plate element can also extend over the entire wall disk surface. For this purpose, the installation plate element is preferably prefabricated to measure. On the installation plate element at least one installation line is pre-assembled, which is, for example, a water, heating, electrical or ventilation duct. The installation plate element consists of a base plate, in particular a wood fiber, gypsum fiber or waterproof glued multi-layer wood panel, wherein the at least one installation line preferably between the base plate and the wall disk surface, which is formed from the side walls of the shuttering blocks, is arranged. As a result, the installation plate element on the side facing away from the wall plate, a smooth and flat surface, which serves as a visible surface of the composite wall element. To fix this embodiment of the installation plate element on the wall disk surface strip-shaped strips are provided on the base plate, which extend as spacers over the height and / or width of the base plate and have a thickness which substantially corresponds to the diameter of the at least one installation line. The installation plate element is connected via the strips with the wall plate of formwork blocks, where it can be screwed or glued to the side walls of the shuttering stones for this purpose. Of course, it is also conceivable according to the invention to arrange the installation plate element as a module element on the first wall disk surface.

By pre-assembly of installation lines on the base plate of the installation plate element, there is the advantage that the production of the composite wall element according to the invention is simplified with at least one preassembled installation line. The position and the course of the individual lines can be predetermined for example by markings or special holding means on the base plate. By pre-assembly of the installation cables, it is thus possible that Prefabricate installation plate element independently of the production of the composite wall element.

For additional attachment of the installation plate element, this can be connected via mechanical fastening means with the wall plate. The fasteners are either inserted into the joints of formwork blocks or screwed into the side walls of the shuttering blocks.

According to a preferred embodiment of the installation plate element, this has on the side wall applied to the wall on a plaster layer inside. When using a waterproof coating, the composite wall element according to the invention is thus also suitable as a wall for sanitary rooms, wherein the coating replaces the attachment of tiles on the side facing away from the wall plate of the installation plate element. For accommodating furnishings such as shelves, the installation plate member may be provided with openings which receive the furnishings in the installation plate member.

By arranging an installation plate element according to the invention on the wall disk surface of a composite wall element, the time for producing such a device is considerably shortened, whereby the degree of prefabrication of the individual components increases and thus the costs for producing a prefabricated transportable composite wall element decrease.

According to a further embodiment of the installation plate element, it can also be provided that the installation plate element comprises a meandering guided over the base plate pipeline, which serves for cooling or heating of a composite wall elements according to the invention enclosed space. For this purpose, a liquid or gaseous cooling or heating medium is passed through the pipeline.

According to a further embodiment of the invention may be arranged on at least a portion of the second wall disk surface, a pre-wall pane having a vertically continuous cavity for receiving at least one installation line. Preferably, the prewall wall consists of successively arranged rows of Shuttering stones or glued together multi-layer wood panels that enclose the cavity. To connect the installation line to, for example, a sanitary device, the prewall wall has at least one opening from which the installation line arranged in the cavity extends outwards. When using additional shuttering blocks for the pre-wall pane they can be glued with their side walls with the second wall disk surface, wherein the cavities of the wall plate and the front wall pane are separated from each other. The prewall wall has on the side facing away from the second wall surface outside a flat surface, which preferably extends plane-parallel to the second wall disc surface of the wall plate and may be provided with a plasterboard for receiving tiles.

By arranging a prewall wall for receiving at least one installation line to the second wall disk surface, it is possible to prefabricate a simple erected on the site composite wall element, which can be used as a wall for a sanitary room. When using the prewall wall for a sanitary room, for example, the cistern of a toilet can be arranged in the cavity.

According to the invention, an opening may be provided in the pre-wall pane, which opening extends into the cavity of the pre-wall pane. In the opening in this case a frame, in particular a frame made of interconnected plate strips, inserted, which closes the cavity of the prewall wall to the outside. In the bathroom, these openings in the front wall pane can be designed as recessed shelves and absorb bath utensils.

To attach a shelf, a sink or a toilet bowl to the front wall pane, it may be provided according to the invention that stiffening ribs are arranged in the cavity of the prewall wall, so that the fastening bolts of the sink or toilet bowl through the cavity of the prewall wall through to the with extend liquid concrete fillable cavity of the wall plate inside. In this way it is prevented that when attaching a sink or a toilet bowl, the pre-wall pane is damaged or pressed.

For displacing and transporting the composite wall element according to the invention, it can be provided according to the invention that at one of the cavity of the wall plate delimiting Inside a strap made of webbing is attached to the hook of a hoist can engage. It has proven to be particularly advantageous here to arrange the Gurtbandschiaufen on the reveal panels, for which purpose preferably a groove is introduced into the reveal plate, in which the belt is glued and nailed to the Laπbungsplatte.

The object mentioned at the outset is also achieved by a method for producing a composite wall element according to the invention, in which, in a first method step, at least one plate-shaped module element is arranged along a mounting plane of a supporting device. The at least one module element is in this case flush with the preferably flat outer surface on the mounting plane, wherein the other flat outer surface of the at least one Moduliements serves as a contact surface for the shuttering blocks. According to a variant of the method according to the invention, provision may also be made for more than one module element to be arranged along the mounting plane, wherein the module elements are connected to one another without gaps at their end faces, in particular adhesively bonded. As an alternative to gluing, it can also be provided according to the invention that, after the arrangement of the module elements along the mounting plane, a horizontally acting compressive force is applied to the outer end faces of the module elements, which presses the adjoining end faces of the module elements flush against each other, before they are pressed together Glued formwork stones.

The module element is preferably a thermal insulation board, in particular a wood soft fiber insulation board, but it is also possible to use a plate-shaped element made of plasterboard or another material. To produce an outer wall with a photovoltaic system, it is possible, for example, to arrange a plurality of zincplate containers along the mounting plane, which preferably have the same cross-sectional thickness as the module element and receive solar modules after the composite wall element has been produced.

After arranging the at least one module element along the mounting plane shuttering stones, in particular Holzspanschalungssteine be arranged along the planar outer surface of the module element in superimposed rows in a second process step. Due to the row-shaped arrangement of the shuttering blocks form the cavities of the over and next to each other arranged formwork blocks a continuous cavity in the Wall disc, wherein the butt joints of the arranged in superposed rows formwork blocks are arranged offset from each other. Before the laying-on or juxtaposing of formwork blocks in the dressing, an adhesive is applied to the flat outer surface of the at least one module element and on the upper, lower and end sides of the adjoining shuttering blocks, so that the shuttering blocks both with each other and with the at least one module element be glued. When arranging the shuttering blocks and connecting the shuttering blocks together, they are connected to each other via a connecting profile which extends along a lower or upper row of shuttering blocks. In a connection profile extending along the lower row of shuttering blocks, the shuttering blocks can be arranged, for example, on the connection profile and adhesively bonded thereto. In a connection profile, which extends along an upper row of shuttering blocks, the connection profile, however, can be mounted only after the row-wise arranging the shuttering blocks on the upper edge of the wall plate.

After producing such a composite wall of formwork blocks and modular elements, which may have any length as an endless wall, the composite wall element is cut in a third process step according to the dimensions required for the construction of a building to measure. For this purpose, a cutting device, such as a chainsaw is provided on the support device, which allows an orthogonal to the rows of formwork blocks section of the wall element. Preferably, the wall element can be moved along the mounting plane in the direction of the sawing device, wherein the mounting plane and the plane which supports the composite wall element on the underside, are designed as sliding surfaces.

According to the invention, the cutting angle of the sawing device is arbitrary, preferably in a range of 0 ° to 180 ° to the plane of the outer wall element surface, adjustable, whereby the wall element can also be mitred. When assembling two composite wall elements, for. B. at an angle of 90 ° for the corner of a building, this results in the advantage that at an intersection angle of 45 °, the composite wall panels must be glued to their abutting surfaces only flush with each other. Due to the flush bonding of composite wall elements extending in the vertical and horizontal directions cavities of the wall slices are interconnected.

After pouring the interconnected cavities of the two composite wall elements with concrete, in particular precast concrete, these are connected to each other both via the adhesive bond in the corner and on the concrete skeleton formed in the cavities. Furthermore, there is the advantage that the abutment surfaces of two abutting, according to the invention produced composite wall elements have a large adhesive surface and thus a good bond between the composite wall elements is ensured. In addition, the flush connection of the composite wall elements prevents thermal bridges in the area of the joint. When using module elements made of a thermal insulation material, the composite wall element produced according to the invention, for example, as an outer wall for a building usable.

By taking place outside the construction site, d. H. Factory prefabrication of the composite wall element accounts for the necessary on the construction site scaffolding for attaching modular elements. Thus, a wall element for a building can be produced in a short time, which can be produced in the use of insulation boards as a module element in the thermal insulation composite system. In addition, due to the prefabrication, there is the advantage that the module elements in the production site of the wall elements according to the invention are easier to handle than on a construction site, whereby module elements in a large format can also be used. Furthermore, in comparison to an erection of a composite wall of shuttering blocks and modular elements on the construction site, the influence of weathering is only of minor importance, since the connections, in particular the adhesive connections between the shuttering blocks and the module elements, can be produced regardless of weather conditions in production halls. As a result, a consistent quality and a high dimensional accuracy of the composite wall element according to the invention are ensured.

According to the invention, it is of course also conceivable, instead of the at least one module element to arrange the formwork blocks along the mounting plane in a first process step, wherein the at least one module element is mounted on the side walls of the formwork blocks forming a flat wall disk surface.

According to a further embodiment of the method according to the invention, the composite wall element is cut into a first and a second wall plate, wherein the first and second wall plate are connected to each other via the at least partially along the upper or lower row of formwork blocks extending connection profile.

In FIG. 1 is a mounting plane 58, a support plane 64 and a sectional plane 66 of a sawing device 68 by a supporting device not shown for producing a composite wall element 1 of formwork blocks 4 and plate-shaped module elements 16 according to the invention. In the manufacture of the composite wall element 1, the individual components 4, 16 are arranged along the mounting plane 58, wherein the components are displaceable on the support plane 64 along the mounting plane 58.

In a first method step, at least one plate-shaped module element 16 is arranged along the mounting plane 58. In this case, the module elements 16 form a substantially planar positioning surface 60 facing away from the mounting plane 58 and a common outer side facing the mounting plane 58, which constitutes the outer side surface of the composite wall element 1 as a composite wall element surface 62. For the production of an outer wall, the module element 16 may consist of an insulating material, such as rock wool or a wood soft fiber, whereas the module element may be a plasterboard or gypsum fiber board when using the composite wall element as the inner wall.

To produce a wall plate 2, the shuttering blocks 4 are arranged in a further process step along the planar Anstellfläche 60 of the modular elements 16 with an offset of the butt joints 70 in superimposed rows, the lowest row of formwork blocks 4 is arranged in a U-shaped connection profile 18, which connects the shuttering blocks 4 together. After the row-shaped arranging of the shuttering blocks 4 in association, the side walls 10 of the shuttering blocks 4 form a first and second planar wall disk surface 12, 14, wherein the first wall disk surface 12 is connected to the contact surface 60 of the module elements 16.

Additionally or alternatively to a connection profile 18, which extends along the bottom row of shuttering blocks 4, it may be provided according to an embodiment, not shown, that the shuttering blocks 4 of the top row of the wall plate 2 are connected to each other via a connecting profile.

In the FIG. 1 and FIG. 2 Formwork blocks 4 shown have a continuous cavity 6, which is bounded by the side walls 10 and end walls 72. To connect the cavities 6 of shuttering stones 4 arranged side by side in the horizontal direction, the end walls 72 each have recesses 8. After joining the shuttering blocks 4 with the module elements 16 thus formed in the form of shuttering blocks 4 wall plate 2 is formed in the vertical and horizontal direction continuous cavity, which can be filled at the construction site with liquid concrete. The concrete skeleton in the cavity of the wall plate 2, which is formed by the cavities 6 of the shuttering blocks 4, gives the composite wall element 1 in this case the required load capacity, which is necessary for the removal of loads.

Hereinafter, the cavity of the wall plate 2 for the sake of simplicity, also referred to by the reference numeral 6 of the cavities of the shuttering blocks 4.

To produce a connection of the shuttering blocks 4 with each other and with the module elements 16 is on the in FIG. 2 shown end faces 72, top 74 and bottom 76 of the shuttering stone 4 and on in FIG. 1 illustrated Anstellfläche 60 of the module elements 16 preferably applied an adhesive, which can be supplemented by a mechanical connection between the shuttering blocks 4 and the module elements 16 additionally.

For this purpose, at the in FIG. 1 Not shown supporting device provided a sawing device 68, which is for example a chain saw can, which intersects the composite wall element 1 in the vertical direction from the top to the bottom row of shuttering blocks 4 along the cutting plane 66. The cutting angle of the sawing device 68 and thus also the cutting plane 66 can be adjusted at any angle to the outer composite wall element surface 62 or to the mounting plane 58, so that the composite wall element 1 can be mitred.

As the illustration in FIG. 1 can be seen, a plaster layer 82 can be applied to the second wall disk surface 14. The plastering of the second wall disk surface 14 can be done on the support device before or after the cut of the composite wall element 1. Instead of the order of a plaster layer, however, it may also be provided that plate-shaped module elements, in particular plasterboard panels or panels with an integrated wall surface heating, are also fastened to the second wall panel surface 14.

In the installation lines 42 are, for example, water pipes, conduits or other domestic supply and exhaust pipes, as they are common in a residential and office buildings. The spacers 92, which preferably consist of a wooden strip, are connected to the base plate 90, for example, by nailing or gluing, so that the installation plate element 48 can be fastened together with the preassembled installation lines 42 as a component in the region of the second wall plate surface 14. The side facing away from the second wall surface 14 of the base plate 90 has a smooth and planar surface, which is arranged plane-parallel to the second wall disc surface 14. The base plate 90 here preferably consists of a multi-ply wood panel, but may also consist of a material such as plasterboard, gypsum fiber or the like. The surface of the base plate 90 may be provided with a coating which does not need to be processed as a finished wall surface after the establishment of a building of composite wall elements 1 according to the invention and the application of an interior plaster or wall tiles is unnecessary.

In addition to an arrangement of installation lines 42 on an installation plate member 48, it may according to an in FIG. 4 embodiment shown further provided that the composite wall element 1 consists of a first and second wall plate 2.1, 2.2, between the end faces 26, 28 a duct 38 for receiving installation lines 42 is arranged. The first and second wall disk 2.1, 2.2 and the duct 38 are at the bottom or top over the in FIG. 4 Not shown connecting profile connected to each other, which extends along the top or bottom row of shuttering blocks 4 of the first and second wall plate 2.1, 2.2.

In order to protect the various installation lines 42 from damage and deformation by the concrete pressure when filling the cavity of the wall plate 2 with concrete, these include a stabilizing protective casing.

As from the illustration in FIG. 5 It can be seen, in the wall plate 2 in the region of the second wall disc surface 14, a recess 40 is provided which is closed by a shutter plate 44 with an installation line 42 disposed thereon. The incision 40 in the wall plate 2 extends at least partially over the height of the wall plate 2 away, wherein for introducing the incision 40, the side walls 10 and end walls 72 of the shuttering blocks 4 are partially removed. The size of the opening of the incision 40 in the wall plate 2 corresponds substantially to the size of the Abschalplatte 44 so that the Abschalplatte 44 reliably seals the incision 40 when filling the cavity 6 with liquid concrete. On the cavity 6 facing side of the Abschalplatte 44 an installation line 42 is attached, which is inserted together with the Abschalplatte 44 in the recess 40. In order to avoid a sound transmission of flow noise from the installation line 42 on the wall plate 2 or the Abschalplatte 44, the installation line 42 is surrounded by a layer 98 of a sound-absorbing material.

In addition to an attachment of the installation line 42 to the Abschalplatte 42, which in a similar way in FIG. 8 is shown in a cross-sectional view, the installation lines 42 may be glued within the cavity 6 with the end or side walls 72, 10 of the shuttering blocks 4. The bonding of the arranged in the corner region of the shuttering stone 4 within the cavity 6 installation line 42 can be carried out both during the superposition and nebeneinanderanordnens the shuttering blocks 4 or made only after the production of the composite wall element 1. In addition, when ironing the shuttering blocks 4 and bracket 100 in the joints 70 of juxtaposed or stacked shuttering blocks 4 are glued with, wherein the bracket 100 in the Cavity 6 extend into it. The brackets 100 preferably consist of a wire which forms a tab within the cavity 6. After bonding the shuttering blocks 4, the installation line 42 can be guided through the tab of the bracket 100 and glued to the side walls 10 of the shuttering blocks 4. As an alternative to gluing the bracket 100 in the joints, it is also possible according to an embodiment, not shown, to introduce a slot-shaped incision in the side wall 10 of a shuttering stone 4.
