Description

The invention relates to a method for producing a transportable prefabricated building wall element from formwork blocks, in particular wood chipboard formwork blocks, as well as a building wall element which was produced according to this method with the features of claims 1 and 23.

In the field of construction it has been known for a long time to use shuttering blocks to erect building walls. For this purpose, the shuttering blocks with a cavity are placed on top of one another and next to one another like conventional masonry. Due to the flat side surfaces and the low weight of the shuttering blocks, they can also be used by non-construction professionals, especially since the shuttering blocks can be placed on top of and next to one another without a joint.

After the shuttering blocks have been arranged in the association, the wall produced in this way has a cavity which extends in the vertical direction from the top row of stones to the bottom row of stones and can be filled with concrete. In this way there is the possibility of building a monolithic wall without formwork elements that are complicated to set up.

In addition to their low weight and easy processability with simple means, wood chipboard blocks can still be produced in an energy-saving and climate-friendly manner. In a known manner, wood is chipped, mineralized and bound with cement for this purpose. The formwork blocks known from the prior art are preferably rectangular and have cavities in the vertical direction. In addition, recesses are provided on the end faces of the formwork blocks so that after individual rows of such blocks are placed on top of one another to form a building wall, a vertically and horizontally extending cavity results, which can be filled with concrete to produce a monolithic wall.

In the DE 200 15 912 U1 a prefabricated wall element is described in this context, which is made of wood chipboard blocks. To produce the wall element, the wood chipboard blocks are placed on top of one another and next to one another and glued to one another. Due to the low weight of wood chipboard blocks, this wall element is easy to transport and can therefore be prefabricated outside the construction site.

the EP 1 111 150 A1 discloses a method for the production of a transportable prefabricated building wall element, which can be used as an outer wall, from shuttering blocks, in which the shuttering blocks are initially arranged and glued together along a support surface that is slightly inclined relative to the vertical, so that an endless blank for wall elements results, which is only then added is covered with an endless insulating layer. The document does not give any advice to first arrange a layer of plate-shaped insulating elements along the assembly plane and then to glue the shuttering blocks to one another and to the flat contact surface of the insulating elements formed in this way.

Furthermore describes the EP 0 422 039 B1 a method for the production of non-load-bearing partition walls for building construction, in which floor-to-ceiling panels made of plasterboard, gypsum fibers or the like are laid out in the form of a web on a horizontal or inclined base. Hourdis bricks, ie hollow bricks with a continuous channel, made of clay, concrete, plaster or the like, are glued onto the plates. A second layer of panels is then glued onto this structure of plasterboard and Hourdis bricks applied to it, and the wall element sheet produced in this way is divided into individual wall element pieces using a circular saw K. The Hourdis bricks glued to the plasterboard do not have any cavities and recesses which allow continuous filling of the wall elements manufactured in an endless process with concrete, so that they are only suitable for the production of non-load-bearing walls.

After the prefabricated wall elements made of wood chipboard blocks have been transported to the construction site, they are set up at the location provided for the wall, with adjacent wall elements being connected to one another with the aid of assembly elements. After the cavities of the wall elements have been filled with concrete, thermal insulation and an external or internal wall plaster with a plaster base must be applied to their external and internal wall surfaces in addition to the electrical, water and heating installation lines. As a rule, this work is carried out in the conventional manner by construction experts, although this is quite costly due to the high wage and travel costs 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 wall elements erected on the construction site depends to a large extent on the organization of the construction site and can accordingly be different.

Accordingly, it is an object of the present invention to provide a method of manufacture to create a prefabricated building wall element and an easily transportable building wall element produced by this method, which facilitate the construction of a building, considerably shorten the construction time on the construction site, and enable consistent quality.

This object is achieved according to the invention by a method with the features of claim 1 and a building wall element with the features of claim 23.

Further features of the invention are contained in the subclaims.

According to the invention, in a method for producing a transportable prefabricated building wall element from shuttering blocks, plate-shaped insulating elements are arranged along an assembly plane of a support device in a first method step. The insulation elements are flush with one of their flat outer surfaces on the assembly level. The insulating elements arranged one above the other along the assembly plane and next to one another are arranged in such a way that the insulating elements form a flat outer surface on the side facing away from the assembly plane, which serves as a contact surface for the shuttering blocks and is referred to below as an endless contact surface.

In order to prevent slipping or shifting of the same relative to one another when several insulating elements are arranged along the assembly plane, it can be provided that the insulating elements are connected to one another, in particular glued, at their end faces. The insulation elements are preferably thermal insulation boards, in particular soft wood fiber insulation boards, the outer surfaces of which are arranged essentially flat and plane-parallel to one another.

After a first wall section has been created from insulating elements, in a second process step formwork blocks, in particular wood chipboard formwork blocks, are arranged in rows one on top of the other along the flat outer surface of the insulation elements. By arranging the shuttering blocks, the cavities of the shuttering blocks arranged one above the other and next to one another form a continuous cavity in the wall panel, the butt joints of the shuttering blocks arranged in rows one above the other being offset from one another. Before the formwork blocks are placed on top of or next to each other in the association, an adhesive is applied to the flat outer surface of the insulation elements and to the top, bottom and front sides of adjacent formwork blocks, so that the formwork blocks are glued to one another and to the insulation elements. The adhesive used for this purpose is preferably an adhesive tailored to the insulation elements, for example PUR foam when using insulation boards made of Styrofoam, polyurethane or rigid polystyrene foam. The adhesive can be applied to the adhesive surfaces of the shuttering blocks and insulation elements with a spray gun. Furthermore, it can be provided that an adhesive suitable for this purpose is used in each case for the bonding of the insulating elements and the shuttering blocks and for the bonding of the shuttering blocks to one another.

The arrangement of the insulation elements on the assembly level and the arrangement of the shuttering blocks along the flat outer surface of the insulation elements create an endless wall in the thermal insulation composite system, which has both a flat outer wall element surface facing the assembly plane and a flat inner wall element surface facing away from the assembly plane, which consists of the side walls of the Formwork blocks are formed. The flat wall element surfaces of the building conversion element, which are referred to below as the inner endless wall element surface and the outer endless wall element surface, can be produced with a high degree of dimensional accuracy, so that when an outer or inner wall plaster is applied, there is no need to compensate for unevenness and thus less plaster material is required.

At least one panel-shaped cladding element, which is at least one glued plasterboard or gypsum fiber board, is attached to the inner, endless wall element surface. For gluing the at least one cladding element, a layer of adhesive is applied to the side walls of the shuttering blocks, which form the inner, endless wall element surface. This is a filling adhesive that closes or fills the pores and depressions in the side walls of the shuttering blocks and thus reduces the air permeability of the building wall element. In order to prevent the panel-shaped cladding element from slipping along the inner, endless wall element surface before the adhesive dries out, it can also be provided that the at least one cladding element is additionally nailed or clamped to the wall panel made of shuttering blocks after bonding. This has the advantage that the building wall element produced according to the invention can be processed further immediately after the cladding element or elements have been glued and is transportable.

After the production of such a composite wall from shuttering blocks and insulating elements, which can be of any length as an endless wall may have, the wall element is cut to size in a third process step in accordance with the dimensions required for erecting a building. For this purpose, a cutting device, for example a chain saw, is provided on the support device, which enables a cut of the wall element orthogonal to the rows of shuttering blocks. For this purpose, the wall element can preferably be displaced along the assembly plane in the direction of the sawing device, the assembly plane and the plane that supports the building wall element on the underside being designed as sliding surfaces.

According to the invention, the cutting angle of the sawing device can be adjusted as desired, preferably in a range from 0 ° to 180 ° to the plane of the outer wall element surface, whereby the wall element can also be mitered. When assembling two building wall elements, e.g. at an angle of 90 ° for the corner area of a building, there is the advantage that with an intersection angle of 45 ° each, the building wall elements only have to be glued together flush at their abutment surfaces. By gluing the building wall elements flush, the cavities of the wall panels extending in the vertical and horizontal directions are connected to one another. After the interconnected cavities of the two building wall elements have been poured with concrete, in particular precast concrete, they are connected to one another both via the adhesive connection in the corner area and via the concrete skeleton formed in the cavities. Furthermore, there is the advantage that the abutting surfaces of two abutting building wall elements produced according to the invention have a large adhesive surface and thus a good bond between the building wall elements is ensured. In addition, the flush connection of the building wall elements prevents the formation of thermal bridges in the area of the joint. The building wall element produced according to the invention can be used as an outer wall for a building.

Due to the fact that the building conversion element is prefabricated outside the construction site, i.e. at the factory, the scaffolding required for attaching insulation elements is not required on the construction site. The service life of scaffolding is thus also reduced to the time required for applying the external plaster. In addition, because of the prefabrication, there is the advantage that the insulation elements are easier to handle in the production site of the wall elements according to the invention than on a construction site, so that insulation elements in large formats can also be used. Furthermore, in comparison to erecting a building wall from shuttering blocks and insulating elements on the construction site, the influence of the weather is of little importance, since the adhesive connections between the shuttering blocks and the insulating elements can be produced in production halls regardless of the weather. This ensures consistent quality and high dimensional accuracy of the building wall elements.

According to one embodiment, for which no protection is sought, it is also conceivable, instead of the insulating elements, to arrange the shuttering blocks in a first process step along the assembly plane, the insulating elements being glued to the sides of the shuttering blocks facing away from the assembly plane.

In addition to gluing, according to one embodiment of the method according to the invention, the insulating elements and the wall panel formed from shuttering blocks can be connected to one another via fastening means. The connection of the insulation elements to the wall panel made of shuttering blocks can be done, for example, by means of concrete anchors which extend into the cavity of the wall panel. After gluing the insulating elements and the shuttering blocks, the concrete anchor is screwed from the outer endless wall element surface through the insulating element into the side wall of a shuttering block. For this purpose, the concrete anchor can have a self-tapping external thread, which cuts a thread turn into the side wall of the shuttering block into the cavity of the wall panel and thus attaches the insulating element to the wall panel. On the other hand, it is also conceivable that a concrete anchor is inserted into the adhesive joint when the shuttering blocks are being bricked up, with the concrete anchor having to be pushed through the insulation elements in the direction of the assembly plane. After the insulation elements and shuttering blocks have been glued together, a locking washer can be attached to the end of the concrete anchor which extends through the insulation element. The locking washer clamps the insulating element against the wall washer and thus fixes it. For this purpose, the end of the concrete anchor can have an external thread and the locking washer can have a recess with an internal thread, so that the locking washer can be screwed onto the concrete anchor in order to clamp the insulating element.

The additional fastening of the insulation elements to the wall panel prevents the insulation elements from loosening due to insufficient load-bearing capacity of the adhesive connection in the case of insulation elements with a thickness greater than 20 cm or as a result of age-related deterioration in the adhesive strength of the adhesive. Especially when using glued Soft wood fiber insulating elements, which have only a low tensile strength, also have the advantage of dowelling that the insulating element is prevented from tearing open and thus the insulating element from becoming detached from the wall panel. When using concrete anchors as fastening means, the building wall element becomes transportable through the gluing of the insulation elements on the wall panel, the concrete anchors establishing a permanent connection between the insulation elements and the wall panel after the cavity of the wall panel has been filled with concrete. Furthermore, the additional fastening has the advantage that the insulation elements reliably absorb the suction forces that can arise from a wind flow along the free surfaces of the insulation elements and consequently wind suction damage to the building wall element is avoided.

The length and / or height of the insulation elements can essentially correspond to the height and / or length of the wall panel made of shuttering blocks. According to a preferred embodiment of the invention, however, the insulation elements have a greater height than the wall panel. For this purpose, only so many rows of shuttering blocks are arranged along the endless contact surface of the insulating elements that the insulating elements extend in sections over the last row of shuttering blocks and thus beyond the wall panel. This section of the insulating elements extending beyond the wall panel can advantageously be used as ceiling edge formwork for a ceiling panel to be produced on the construction site, which is arranged on the wall panel formed from shuttering blocks. For this purpose, the section of the insulation elements serving as ceiling edge formwork preferably has a protrusion of approx. 18 to 25 cm.

According to a further embodiment of the method according to the invention, it can be provided that in the area of a window or door opening provided in the building wall element, no insulation elements and shuttering blocks are arranged along the assembly plane. The size of the resulting opening in the wall element essentially corresponds to the installation dimensions of a window or door element, with a corresponding lintel shuttering block being arranged in the lintel area of the window or door opening. Such a lintel shuttering block is known from the prior art, wherein it has a length which essentially corresponds to the width of the door or window opening. The recesses and cavities of the shuttering blocks that adjoin the window or door opening are closed with a reveal board with a smooth surface, preferably a cement-bonded wood fiber board. The cavity of the building wall element produced according to the invention, which can be filled with concrete, is thereby sealed in the area of the window or door opening. To attach the reveal panels to the open sides of the shuttering blocks, these are preferably glued and nailed to the shuttering blocks, the nailing being able to be carried out, for example, with the aid of a firing device.

By closing the open sides of the shuttering blocks with a reveal panel with a smooth and even surface, the required sealing strips can be glued directly onto the reveal panel when installing a window or door element. It is therefore not necessary to apply a leveling layer of plaster to create an even reveal surface.

To arrange a window or door opening in the building wall element, it can be provided according to further method steps according to the invention that the wall element is cut into a first and second wall element piece after the insulating elements and the shuttering blocks have been glued. The cut surfaces of the wall element pieces are then closed at least in sections with a reveal panel, the closure preferably being carried out by nailing and gluing the reveal panel to the cut surfaces of the shuttering blocks. After the closure, a lintel element is arranged between the first and the second wall element piece and is glued to a section of the wall element surfaces which is not closed by one of the reveal panels. In addition to closing the open cut surfaces for shuttering the cavity of the wall element pieces, the reveal panels also support the lintel element with their upper edges. In order to prevent the building wall element formed from wall element pieces and lintel element from bending in the direction of the building wall level and transversely thereto, at least one upper first and one lower second connecting bracket are attached along the top and bottom rows of shuttering blocks. The upper and lower connection bracket extend here along the top and bottom row of shuttering blocks and represent an upper and lower end of the building conversion element upper first connection bracket is worn. The connecting angles can be screwed and / or glued to the wall element pieces and / or the lintel element, for example. The connecting angles preferably consist of a galvanized L- or T-shaped metal profile which comprises two legs arranged at right angles to one another. The first leg is on the side walls of the Formwork blocks and lintel elements attached, wherein the second leg runs along an upper or lower side of the formwork blocks or the lintel element and thus supports them.

The lintel element is preferably a U-shaped lintel element known from the prior art, which can be filled with concrete and has a cavity, which consists of the same material as the shuttering blocks and can have thermal insulation arranged on the outside. The thermal insulation can be glued to the lintel element in the form of an insulating element. In order to transfer wall loads, the lintel element also includes reinforcement which, after being filled with concrete, is enclosed by the latter. According to a further embodiment of the invention, the lintel element can consist of U-shaped formwork blocks glued together, the reinforcement arranged in the cavity of the lintel element extending over the length of the lintel element and attached to at least one of the side walls of the formwork blocks. By attaching the reinforcement to the formwork blocks of the lintel element, the flexural strength of the U-shaped formwork blocks glued together is increased so that the lintel element does not bend when the cavity is filled with concrete. For the reinforcement, for example, a lattice tube girder can be used, which can be produced in great lengths and which is cut to the appropriate size for the lintel element. The tubular space carrier preferably has a triangular or square cross-sectional shape, one of the sides of the tubular space carrier being screwed to the side walls of the shuttering blocks. When filling the glued together U-shaped shuttering blocks with concrete, the forces acting on the shuttering blocks are dissipated via the screw connection and the tubular girder, which prevents the lintel element from bending.

To form a window opening arranged within the wall plane, it can furthermore be provided according to the invention that a parapet element is arranged between the cut surfaces of the wall element pieces. The parapet element is glued to the cut surfaces that are not closed by a reveal panel. In order to establish an additional connection between the parapet element and the wall element pieces, the parapet element is mechanically connected to the lower, second connection bracket. Like the wall element pieces, the parapet element also consists of formwork blocks arranged next to and / or one above the other, the respective cavities of which form a common cavity extending in the vertical and horizontal directions. The same shuttering blocks are preferably used for the production of the parapet element as for the production of the wall panel. By gluing the end faces of the parapet element to the cut surfaces of the wall element pieces, the cavities of the wall element pieces and the parapet element are connected to one another. The lower, second connection bracket connects the parapet element with the wall element pieces and also supports it.

The parapet element, like the wall element, is preferably produced by arranging and gluing together insulating elements and shuttering blocks along an assembly plane. Here, the shuttering blocks and the insulating element or elements of the parapet element can be arranged, for example, directly between the cut surfaces of the wall element pieces. On the other hand, however, it is also possible to prefabricate the parapet element like the wall element as an endless wall and, after gluing the shuttering blocks and insulating elements, to cut it to the appropriate length. The length of the parapet element results from the distance between the cut surfaces of the wall element pieces, the distance depending on the installation dimensions of the window element.

By cutting the wall element into at least two pieces and arranging a lintel element between their cut surfaces, a building wall element can be produced in a simple and inexpensive manner, which can be transported to a construction site in a prefabricated manner and comprises a window and / or door element. By attaching a first and second connecting bracket along the wall element pieces and the lintel element or parapet element, the building wall element formed in this way has great flexural rigidity in the direction of the wall plane as well as transversely thereto. This results in the possibility of integrating the window and / or door element into the building wall element at the site of prefabrication without twisting and deformation occurring during transport of the building wall element, which would destroy the glass surfaces of the window and / or door element, which absorb only low compressive stresses . Due to the straight edge of the lower, second connection bracket, this also serves to align the building conversion element on the construction site.

In addition to increasing the wall stiffness, at least one of the connecting angles can also serve as a plaster stop for an inner wall plaster layer to be applied to the inner, endless wall element surface. For this purpose, the at least one connecting bracket has a stop strip which runs at least along the length of the at least first and second wall element pieces and extends from the inner, endless wall element surface extends away. The stop bar has a width that corresponds to the thickness of the plaster layer to be applied. In this way, when plastering the inner endless wall element surface, a uniformly thick layer of plaster can be applied, which corresponds to the required minimum thickness. The plaster stop also represents a closing edge of the plaster layer, which runs in a straight line and evenly along the upper and / or lower row of shuttering blocks.

According to the invention, the shuttering blocks arranged below a window opening can be closed on the top with a reveal panel. Like the other soffit panels, this soffit panel also has a smooth surface and thus facilitates the application of sealing strips and the installation of a window element. In order to simplify the filling of the shuttering blocks arranged below the window opening, the reveal panel has openings through which concrete can be poured into the interconnected cavities of the shuttering blocks. In this way, concrete is poured into the shuttering blocks arranged below the window opening both from the top of the building wall element and through the cavities of the wall element pieces adjoining the window opening, which are connected to the cavities of the shuttering blocks arranged below the window opening.

According to a further embodiment of the method according to the invention, the construction time of a building constructed from building wall elements produced according to the invention can be further shortened if an external plaster base is applied to the outer endless wall element surface formed by the insulating elements. It has been found to be particularly advantageous here to apply a minerally bound adhesive and reinforcing mortar, which is reinforced by a reinforcing fabric, to the surface of the insulating elements. The application of the finishing plaster can be done at the factory in production halls as well as after the bonding of adjoining building wall elements on the construction site.

Instead of the arrangement of insulating elements, according to a further embodiment of the invention, for which no protection is sought, plate-shaped cladding elements are arranged along the assembly plane of the support device. The panel-shaped cladding elements form a flat, endless contact surface that faces away from the assembly plane and on which the shuttering blocks can be arranged in rows. In the same way as in the previously described production of a building wall element with insulating elements, the cladding elements and the shuttering blocks are glued together, so that a composite wall of shuttering blocks and cladding elements is created which has flat, endless wall element surfaces. The cladding element can be, for example, a carrier plate with tiles arranged on it or a plate made of plasterboard or gypsum fiber, which is glued to the shuttering blocks by means of filler adhesive. By replacing the insulating elements with the cladding elements, the building wall element produced in this way can be used as an inner wall element in the construction of a building. Due to the composite construction of cladding elements and shuttering blocks, the building wall element has a high flexural rigidity in the directions of the wall plane as well as perpendicular thereto. When using the filler adhesive to connect the cladding elements and the shuttering blocks, there is the advantage, especially with wood chipboard blocks, that the pores and depressions present in the surfaces of the shuttering blocks are filled by the filler adhesive, which results in an essentially air-impermeable building wall element. The building wall element can thus be used for the construction of a building with a largely airtight building envelope. When gluing plasterboard or gypsum fiber boards, the soundproofing of the building wall element is further improved, with the plasterboard or gypsum fiber boards absorbing the sound waves as a flexible shell.

According to a further method step of the invention, an abrasion-resistant interior plaster, in particular a fiber reinforcement plaster base, can be applied to the inner endless wall element surface. The interior plaster layer is applied over a section of the inner, endless wall element surface. The possibility of prefabrication of the wall element means that the interior plaster is sprayed onto the endless wall element surface, for example. Particularly in times of the year with an increased probability of precipitation, additives can be added to the interior plaster, which reduce the plaster's sensitivity to moisture. In this way, the building wall element provided with an interior plaster can be transported to the construction site without the interior plaster being affected by mechanical or weather-related stresses.

As a result of the possibility of controlling the climatic conditions, such as humidity and air temperature, at the place of manufacture of the building conversion element, an interior and exterior plaster with a good bond with the material of the insulating elements or the shuttering blocks can also be produced. As a result of the controllable environmental conditions, drying tensions and the associated cracks in the plaster can be avoided. In order to reach the joint area of To connect their respective plaster layers to adjoining wall elements, a plaster layer with a thickness that is less than in the remaining area of the endless wall element surface can be applied in a strip-shaped edge region of the endless wall element surfaces. After two adjacent building wall elements have been joined to one another, the plaster layer of lesser thickness in the strip-shaped edge areas can be matched to the thickness of the plaster layer of the remaining wall element surface in this way. To avoid the formation of cracks in the plaster in the area of the butt joints of two interconnected building wall elements, provision can also be made for the adjacent strip-shaped edge areas of the building wall elements to be covered with a strip of reinforcing fabric before another layer of plaster is applied.

To further shorten the construction time required for the construction of a building on the construction site, it can be provided according to a further method step that at least one installation line is attached to the inner endless wall element surface facing away from the insulating elements. The installation line can be, for example, a heating pipeline, an electrical supply line, a water pipeline or a ventilation installation with an associated ventilation element.

According to a further embodiment of the invention, the at least one installation line can be glued directly onto the side walls of the shuttering blocks which form the inner, endless wall element surface. The at least one installation line can be glued using the same adhesive that was previously used for gluing the shuttering blocks. The installation line is preferably arranged under the interior plaster, so that the plaster is only applied after the installation line has been attached to the inner, endless wall element surface. By arranging the building wall element on the support device, the inner endless wall element surface is easily accessible for the attachment of the installation line, the scaffolding required for the production of the wall panel can also be used for the assembly of the installation line.

As an alternative according to the invention to the direct gluing of the installation line, however, it can also be provided that one or more mounting rails with recesses are attached, in particular glued, to the inner endless wall element surface, into which the at least one installation line is inserted, in particular glued or clamped.

Instead of a direct arrangement of at least one installation line on the inner endless wall element surface, at least one installation wall element with at least one installation line preassembled thereon can be arranged along the inner endless wall element surface and glued to it according to a further method step according to the invention. The installation wall element extends over a portion of the inner endless wall element surface. If the inner endless wall element surface does not have any projections or recesses, the installation wall element can, however, also extend over the entire inner endless wall element surface. At least one installation line, which is, for example, a water, heating, electrical or ventilation line, is preassembled on the installation wall element. The installation wall element can consist of a plate-shaped component, in particular a wood fiber or gypsum fiber board. The at least one installation line is preferably arranged between the plate-shaped component and the inner, endless wall element surface, which is formed from the side walls of the shuttering blocks. As a result, the installation wall element has a smooth and flat surface on the side facing away from the inner endless wall element surface, which serves as a visible wall surface. To fasten this embodiment of the installation wall element on the inner endless wall element surface, strip-shaped elements are provided on the installation wall element, which extend over the height and width of the installation wall element and have a height which corresponds to the height of the at least one installation line. The installation wall element can thus be glued to the wall panel made of shuttering blocks via the strip-shaped elements.

The preassembly of installation lines on the installation wall element results in the advantage that the production of a building conversion element according to the invention with preassembled installation lines is simplified. The position and the course of the individual lines can be predetermined, for example, by markings or special holding means on the installation wall element. By pre-assembling the installation lines on the installation wall element, it is possible to prefabricate the installation wall element in a process step that is independent of the production of the building wall element.

In order to permanently connect the installation wall element to the wall panel consisting of shuttering blocks, the installation wall element can after a further process step via fastening means, in particular with itself into the cavity of the building wall element extending concrete anchors to be connected to the wall panel. The fastening means can either be glued into the joints of the shuttering blocks or screwed or hammered into the side walls of the shuttering blocks.

According to a further advantageous embodiment, the installation wall element has an interior plaster on the side facing away from the wall panel.

In order to also arrange the installation wall element in the area of a window or door opening provided in the wall, it can have a recess which essentially corresponds to the installation dimensions of a window or door element.

By arranging an installation wall element according to the invention on the endless wall element surface of a building conversion element, the time to manufacture such a building element is considerably reduced, the degree of prefabrication of individual components increasing and thus the costs for the production of a prefabricated building conversion element being reduced.

According to a further embodiment of the invention, the at least one installation line can be guided through the cavity of the wall panel. Inside the cavity, the installation line is attached to an end wall and / or side wall of a shuttering block. As the at least one installation line runs through the cavity of the building wall element, there is no need to plaster installation lines that are arranged on the inner, endless wall element surface. Furthermore, there is the advantage that after the cavity has been filled with concrete, the installation line is protected from mechanical damage both by the side walls of the shuttering blocks and by the encasing concrete layer, as can occur, for example, through holes in the building wall element in the case of lines arranged outside the cavity .

In this context, fastening the installation line in the corner area of a front and side wall has proven to be particularly advantageous, since the course of the installation line through the cavity of the wall panel is predetermined by the superimposed corner areas of the superimposed rows of shuttering blocks. Before a plaster is applied, the course of the installation line through the cavity can still be traced from the outside based on the course of the joints in the shuttering blocks.

When arranging the at least one installation line in the cavity of the wall panel, one or more openings can be provided according to the invention in at least one side wall of a shuttering block of the wall panel, through which the at least one installation line is led out of the cavity and thus out of the wall panel. After the wall panel has been formed from shuttering blocks, the at least one installation line can be inserted into its cavity, for example, from one of the open sides of the wall panel. In order to lead the installation line out of the cavity of the wall panel again in the area of the inner endless wall element surface, an opening can be cut or drilled in the side wall of a shuttering block. When laying an electrical installation line, this results in the possibility of providing an electrical connection within the endless wall element surfaces.

According to an advantageous embodiment of the invention, the at least one installation line is surrounded by a protective jacket which protects the installation line from damage when the cavity is filled with concrete.

According to the invention, a fastening means can be provided for fastening the installation line in the cavity of the wall panel, which fastener attaches the installation line to a side or end wall of a shuttering block within the cavity. In addition to gluing, the installation line can also be mechanically connected to the shuttering block with a clamp or a spacer.

After a further method step, it can be provided for fastening the installation line in the cavity of the wall panel that an incision is made in at least one side wall of a shuttering block. The incision is preferably slot-shaped, so that a section of a flexible and dimensionally stable fastening means can be introduced or pushed into the cavity from the inner, endless wall element surface. The section that extends into the cavity forms a loop. When the installation cable is inserted through one of the open sides of the wall panel, it is passed through the loop. By fixing the portion of the fastening means located outside the cavity, for example by fixing it on the inner endless wall element surface, the installation line is fastened to the side wall of a shuttering block in the cavity. The fastening means can be, for example, a wire or a cable tie, which has a diameter or a width of 2 to 10 mm. The wire or the cable tie are shaped in such a way that a loop is created through the incision can be inserted into the cavity. Furthermore, the free ends of the wire or cable tie extend through the incision out of the cavity and can thus be attached to the inner endless wall element surface. By pulling on the free ends, the loop arranged in the cavity surrounds the installation line and thus attaches it to the side wall of the shuttering block in which the incision is made.

According to a further embodiment of the invention, the at least one installation line arranged in the cavity can be an empty pipe into which, for example, an electrical line can be inserted. The empty pipe is arranged over the length of the building wall element in its cavity. The empty pipe is preferably a plastic pipe which, when the cavity is filled with concrete, withstands the concrete pressure and does not deform. When arranging the shuttering blocks, the empty pipe can, for example, be fastened to the side walls of a row of shuttering blocks, in particular glued, before a further row of shuttering blocks is put on. The empty pipe preferably runs in the horizontal direction. In order to connect the empty pipe of a building wall element with the empty pipe of another building wall element produced according to the invention, the empty pipe runs through the wall panel at the same height in each building wall element, the connection of the empty pipes in the joint area of two adjacent building wall elements via a connecting sleeve. After the construction of a building from building wall elements according to the invention, an opening can be cut in the wall panel at the level of the empty pipe, through which the empty pipe can be reached and through which, for example, an electrical line can be inserted into the empty pipe. Due to the possibility of connecting the empty pipes of adjoining building wall elements, an electrical line can thus be routed from one building wall element to an adjacent building wall element, with the electrical line coming out of this and thus out of the cavity of the building wall element through the incision of an opening at the level of the empty pipe can be performed. In this context, when a window is arranged in the building wall element, it is of course also provided that an empty pipe is also arranged in the parapet element. In order to exclude mutual electromagnetic interference of electrical lines with different voltages, two empty tubes are provided according to the invention, which are arranged at a distance from one another and are thus shielded from one another. In this case, the electrical lines of the electrical supply network, which are subjected to the mains voltage, are routed through one empty pipe, while the electrical lines for the transmission of data signals etc., which carry only a low voltage of a few volts, run through the other empty pipe.

According to a further embodiment of the invention, the at least one installation line can be a heating pipeline which is arranged on the side of the wall panel assigned to the inner endless wall element surface. The heating pipeline extends over the length and / or height of the building conversion element. This arrangement of the heating pipeline means that the room is heated over the entire wall surface, which creates a pleasant room climate. On the other hand, however, there is also the possibility of using such a wall heating system for cooling instead of heating, with a liquid or gaseous cooling medium being circulated through the at least one heating pipe for this purpose. The wall surface heating can also be designed as a capillary tube system.

To further improve the room climate in a room enclosed by building wall elements produced according to the invention, it can be provided according to a further method step according to the invention that the at least one installation line is a ventilation duct, preferably a flat duct with a low overall height, which is fluidically connected to a ventilation element. Here, the ventilation element is arranged in the area of the inner endless wall element surface, whereby it can be attached to the side walls of the shuttering blocks as well as being integrated on an installation wall element or in the side wall of a shuttering block. The ventilation duct and the ventilation element are used for ventilation, whereby according to the invention a ventilation element for ventilation can be arranged in a lower region of the wall element and a ventilation element for ventilation can be arranged in an upper region of the wall element. The ventilation elements have openings for the exit of supply air or entry of exhaust air.

A ventilation system produced according to the invention has the advantage that a building constructed from building wall elements produced according to the invention can be ventilated in a controlled manner. This is particularly important in energy-saving houses, since, due to the seals in the area of the windows and doors, an exchange of air masses with the outside air is only possible to a small extent.

For the production of a prefabricated building conversion element with an integrated Sewage pipe, after a further process step, further shuttering blocks can be arranged along the inner endless wall element surface. For this purpose, the inner endless wall element surface preferably has neither an interior plaster nor structural elements attached to the endless wall element surface in the area in which the further shuttering blocks are arranged. The further formwork blocks are arranged in rows one above the other, so that a front wall panel is created which has a cavity that is continuous at least in the vertical direction for receiving at least one sewer pipe. For this purpose, the further shuttering blocks of the front wall panel each include a cavity which, as in the case of the shuttering blocks of the wall panel, is delimited by side and end walls. To form a front wall panel, the further shuttering blocks are glued to one another as well as to the side walls of the shuttering blocks of the wall panel, which form the inner, endless wall element surface, when they are placed on top of one another. In this way, the wall panel formed from the formwork blocks and the front wall panel formed from the further formwork blocks are connected to one another. The further formwork blocks of the front wall panel form a flat front wall element surface on the outer sides facing away from the inner endless wall element surface, which preferably runs plane-parallel to the inner endless wall element surface of the wall panel. By arranging a front wall panel for receiving at least one sewage pipe on the inner endless wall element surface, it is possible to prefabricate a building wall element which is easy to set up on the construction site and which can be used as a wall element for a sanitary room.
The front wall panel can extend in sections over the height of the building wall element. For this purpose, the front wall panel preferably consists of fewer rows of shuttering blocks than the wall panel, the open sides, in particular the open sides of the top row of shuttering blocks, being closed with a flat end plate with a smooth surface.

According to a further embodiment, the further shuttering blocks of the front wall panel have a smaller width than the shuttering blocks of the wall panel. This makes it possible to adapt the width of the shuttering blocks to the outer diameter of the sewer pipe and to reduce the overall width of the prefabricated building conversion element.

In order to fasten sanitary facilities, at least one assembly element can be integrated in the front wall panel, which can be, for example, a bolt that extends outward from the front wall panel. To dissipate the forces acting on the mounting element, the mounting element runs through the front wall panel and extends into the cavity of the wall panel. After the cavity in the wall panel has been filled with concrete, a bond is created between the mounting element and the concrete, so that the mounting element is clamped and anchored in the wall panel. In addition to being anchored in the wall panel, it is possible for the assembly element to be supported as it extends through the side wall of a shuttering block of the wall panel and by the side walls of a further shuttering block of the front wall panel.

According to a further embodiment of the method for producing a building conversion element according to the invention, the inner endless wall element surface and the front wall element surface of the front wall panel, which extends only in sections over the height and / or length of the building conversion element, form a common surface. Here, an interior plaster, in particular a fiber reinforcement plaster base, can be applied to the common surface of the wall panel and the front wall panel. Due to the possibility of prefabrication of the wall element, the interior plaster can be sprayed onto the common surface in a simple manner. Particularly in times of the year with an increased probability of precipitation, additives can be added to the interior plaster, which reduce the plaster's sensitivity to moisture. In this way, the building wall element provided with an interior plaster can be transported to the construction site without the interior plaster being affected by mechanical or weather-related stresses.

Instead of applying a damp plaster, it is possible according to a further embodiment to apply a panel-shaped cladding element to the common surface. The cladding elements can, for example, be plasterboard or gypsum fiber boards, which are glued to the common surface of the front wall panel and the inner endless wall element surface with a filler adhesive and are additionally nailed. The cladding elements can thus be fastened in the same way as was previously described for the fastening of cladding elements to only the inner, endless wall element surface.

To produce a building conversion element according to one of the steps according to the invention, the assembly plane of the support device has an angle between 70 ° and 90 °, preferably an angle of 80 °, to the horizontal. This makes it possible to use the insulating elements and the shuttering blocks or the cladding elements and the Lean the formwork blocks against the assembly level when arranging them. For this purpose, the support device can furthermore have a support plane on which the respective components stand. The support plane is arranged at a substantially right angle to the assembly plane.

The object mentioned at the beginning is also achieved by a building wall element produced according to the method according to the invention, which is prefabricated and transportable. The building wall element can have plumbing, heating, ventilation and electrical installations, the connections of which to the respective supply networks form a common connection point. The common connection point is preferably arranged in a lower area of the building conversion element.

According to the invention, the common connection point of the plumbing, heating, ventilation and electrical installations can have a coupling connection via which the installation lines of the building conversion element produced according to the invention can be connected to the ventilation device and the water, heating and electrical supply network on the construction site.

The parapet element 98 consists of several formwork blocks arranged one above the other 4th which like the one in 2 Shuttering block shown, a cavity 24 , a recess 26th as well as front and side walls 16 , 22nd exhibit. The manufacture of the parapet element 98 can be done in the same way as making an in 1 shown one-piece building conversion elements 1 take place, however, the height of the insulation elements 2 and the number of rows of formwork blocks 4th at the height of the parapet below the window element 104 is matched. When manufacturing is in the cavity 24 a lower row of shuttering blocks 4th an empty pipe running in the horizontal direction 40 on the side walls 22nd the shuttering blocks glued. After gluing the shuttering blocks 4th and the insulation elements 2 as well as inserting an empty pipe 40 is this along the in 1 mounting level shown 6th Erected endless wall element with the sawing device 30th cut in length as required for the arrangement of the parapet element 98 between the in 7a cut surfaces shown 102.1 , 102.2 is required. The length of the parapet 98 essentially corresponds to the length of the lintel element 96a . On the top of the parapet 98 is a reveal panel 100c attached, which are the interconnected cavities 24 the shuttering blocks 4th of the parapet 98 locks. The reveal panel 100c here has an opening 101 on. By connecting the cavities of the in 7a wall element pieces shown 1.1 , 1.2 and the parapet 98 can thus concrete both from the adjacent wall element pieces 1.1 , 1.2 as well as through the opening 101 into the cavity 24 of the wall element piece 98 be introduced.

Between the parapet 98 and the lintel element 96a is a window element 104 arranged, which in 7b is not shown for technical reasons. The fall element 96a consists of U-shaped shuttering blocks, which point in the direction of the window or door element 104 , 106 are closed and glued together at their end faces. To after backfilling the lintel element 96a Using concrete to give this the necessary flexural rigidity is in the lintel element 96a continuous reinforcement 114 arranged, which extends over its length. The reinforcement is a triangular tubular lattice girder 114 , the one with the lower leg 122 of the U-shaped lintel element 96a is screwed, causing a deflection of the lintel element 96a is already prevented when filling with concrete. Like the parapet 98 also has the lintel element 96a an insulating element 2 on its outside on. The insulating element extends over the top of the lintel element 96a away and forms a paragraph 112 used as slab edge formwork for one on the building wall element 1 to be attached ceiling plate is used.
