Description

The The invention relates to a method for producing a transportable prefabricated Composite wall element made of shuttering stones, in particular wood-paving stones, and a composite wall element made by this method.

in the Area of construction, it has been known for some time Shuttering stones for the construction of building walls to use. For this purpose, the formwork blocks having a cavity are like conventional masonry in association with each other and side by side set. Due to the flat side surfaces and the low The weight of formwork blocks can also be used by non-construction professionals be processed, especially as the shuttering stones seamlessly up and can be placed next to each other.

To arranging the shuttering stones in the dressing, the resulting Wall a cavity that extends vertically from the top Stone row extends down to the lowest stone row and with concrete is fillable. In this way, there is the possibility a monolithic wall without complicated to be erected formwork elements build.

Next the low weight and good processability with simple Funds are Holzspanschalststeine continue to be energy efficient and climate-friendly to produce. In a known manner, this wood is cut, mineralized and cement-bound. The from the state of the art known shuttering blocks are preferably rectangular and have cavities in the vertical direction. About that In addition, at the front sides of the formwork blocks recesses provided so that after the juxtaposition of individual rows Such stones to a building wall in a vertical and horizontal extending cavity for manufacturing a monolithic wall can be filled with concrete.

In the DE 200 15 912 U1 is described in this context, a prefabricated wall element, which is made of Holzspanschalungssteinen. To produce the wall element, the Holzspanschalungssteine be up and placed side by side and glued together. Due to the low weight of Holzspangenalungssteinen this wall element is easily transportable and can therefore be prefabricated outside the construction site.

To the transport of such prefabricated wall elements from Holzspanschalungssteinen On the construction site these are provided on the wall Place set up, with adjacent wall elements with Help of mounting elements are interconnected. After filling the cavities of the wall elements with concrete need at the outer and inner wall surfaces next to the Electric, water and heating installation lines still a thermal insulation and an exterior or interior wall plaster applied with plaster base become. As a rule, these works are based on conventional Manner performed by construction professionals, this being due the high wage and approach costs is quite expensive and the progress of these works from those prevailing on the construction site Weather conditions depends. Add to that the quality and dimensional accuracy of wall elements erected on the construction site to a large extent the organization of the construction site is dependent and correspondingly different can.

Accordingly It is an object of the present invention to provide a method of preparation a prefabricated building wall element and a post easily transportable produced by this process Building wall element to create the construction of a building makes construction time at the construction site considerably shorter and a consistent quality.

These Task is according to the invention by the features from claim 1 and 30 solved.

Further Features of the invention are contained in the subclaims.

According to the Invention are in a process for producing a portable prefabricated building wall element made of shuttering stones in a first step, plate-shaped module elements arranged along a mounting plane of a support device. The module elements lie here with one of their flat outer surfaces flush with the mounting plane. The way along the mounting plane above and next to each other arranged module elements are arranged in the way that the module elements on the mounting plane opposite side form a flat outer surface, as a contact surface for the formwork blocks serves.

In order to prevent slippage or displacement of the same relative to one another in the arrangement of a plurality of module elements along the mounting plane, it can be provided that the module elements are connected to one another at their end faces, in particular adhesively bonded. In order to arrange the module elements seamlessly next to and above each other, it can also be provided as an alternative to a bond, however, that according to the Anord tion on the mounting plane parallel to the plane of the mounting plane acting pressure force is applied to the module elements, which presses the end faces of the module elements flush against each other. The module elements are preferably thermal insulation boards, in particular Holzweichfaserdämmplatten, or plate-shaped elements made of plasterboard or other material having two mutually parallel planes or surfaces with which they can be arranged on the mounting plane. As an alternative to the use of modular elements made of an insulating material, it can also be provided according to the invention that module elements made of different Dämmstofen be arranged side by side or one above the other. For the production of an outer wall with a photovoltaic system, it is for example possible to arrange next to the insulating elements and containers made of zinc sheet along the mounting plane, which have the same cross-sectional thickness as the insulating elements and absorb the solar modules after the production of the composite wall element. In this context, the container for receiving the solar modules may have a drive that changes the angle of the solar modules to the outer wall element surface depending on the position of the sun. In order to avoid cold spots in the area of these containers, they can have a heat-insulating layer on the rear side facing away from the mounting plane. On the other hand, however, it can also be provided that an insulating element with a smaller heat transfer coefficient is arranged in the region of the container, so that the k value of the composite wall element has substantially the same size.

To the creation of a first wall section of modular elements in a second process step shuttering stones, in particular Timber shears, along the flat outer surface the module elements arranged in superimposed rows. By arranging the shuttering blocks form the cavities the above and side by side shuttering stones a continuous cavity in the wall plate, wherein the butt joints the shuttering blocks arranged in superimposed rows offset from one another. Before the up or side laws of formwork stones in the dressing is on the flat outer surface of the Module elements and on the top, bottom and front sides of each other bordering formwork stones applied an adhesive, so that the shuttering blocks both together and with the module elements be glued. As an adhesive, this is preferably a on the modular elements of matched adhesive, such as polyurethane foam when using insulation boards made of polystyrene, polyurethane or polystyrene foam, used. The adhesive can do this with a spray gun on the adhesive surfaces of formwork blocks and the module elements are applied. Furthermore, it can be provided be that for the bonding of modular elements and shuttering stones as well as for gluing the formwork blocks together in each case a suitable adhesive is used.

By the arrangement of the module elements on the mounting plane and the arrangement the formwork blocks along the flat outer surface The modular elements creates an endless wall in the composite system, the both a planar outer facing the mounting plane Wall element surface as well as one of the mounting plane facing away level inner wall element surface which, from the side walls formwork blocks are formed. The flat wall element surfaces of the composite wall element are in this case with a high dimensional accuracy can be produced so that less adhesive material for bonding the module elements with the formwork blocks is required and when ordering a Exterior or Innenwandputzes a balance of bumps eliminates, which is offset by the amount of cleaning material a conventionally manufactured wall reduced.

To the production of such a composite wall of shuttering stones and module elements, which as an endless wall of any length can, the wall element in a third process step according to the required for the construction of a building Dimensions cut to size. For this purpose is on the support device a cutting device, for example a chain saw, provided, the one orthogonal to the rows of formwork stones section of the wall element allows. Preferably, the wall element can do so along the mounting plane in the direction of the sawing device be moved, with the mounting plane and the plane that the Composite wall element supported on the underside, designed as sliding surfaces are.

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 your abutting surfaces only flush with each other. By the flush bonding of the 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 ready-mixed concrete, these are connected to each other both via the adhesive bond in the corner region as well as 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 avoids the formation of 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 an off-site, d. H. factory Prefabrication of the composite wall element accounts for the construction site the scaffolding necessary for attaching modular elements. Thus, in a short time a wall element for a building can be produced, which in the use of insulation boards can be produced as module elements in the thermal insulation composite system is. In addition, due to the prefabrication of Advantage that the modular elements in the manufacturing facility the wall elements according to the invention easier to handle are considered on a construction site, which also makes modular elements in large Formats are usable. Furthermore, compared to a construction a composite wall of shuttering blocks and modular elements on the Construction site the influence of the weather of little importance, because the adhesive joints between the formwork blocks and the modular elements irrespective of weather conditions can be produced in production halls. This will be a consistent quality and a ensures high dimensional accuracy of the composite wall elements.

For an end-side connection of a further composite wall element in the area of the inner or outer wall element surface it may be provided according to the invention that on the inner or outer wall element surface in the vertical direction one above the other arranged holes be introduced into the composite wall element, extending from the inner or outer wall element surface up to extend the cavity of the wall plate of formwork stones into it. The cavity of the further composite wall element, which over its end face on the inner or outer wall element surface the composite wall element is connected, is about in the inner or outer wall element surface provided holes connected to the cavity of the composite wall element.

According to the invention it also conceivable, of course, instead of the module elements the shuttering blocks in a first step along the Assemble assembly level, the module elements on one level forming side walls of shuttering stones are glued, which are facing away from the mounting plane.

additionally for bonding can according to one embodiment the method according to the invention, the module elements and the wall plate formed from formwork bricks Fixing means are connected to each other. The connection the module elements with the wall plate of formwork blocks can For example, be done by concrete anchors, which are in the cavity extend the wall plate into it. After bonding the module elements and the shuttering blocks, the concrete anchor is thereby from the outer Wall element surface forth through the module element in screwed the side wall of a formwork blocks. The concrete anchor can this have a self-tapping external thread, which forms a thread in the side wall of the formwork stone until it cuts into the cavity of the wall plate and thus the Module element attached to the wall plate. On the other hand it is too conceivable that when walling the formwork blocks a concrete anchor is inserted into the adhesive joint of formwork blocks, wherein the concrete anchor in the direction of the mounting plane through the module elements must be put through. After gluing together module elements and formwork blocks can be attached to the end of the concrete anchor extending through the module element, a lock washer be attached. The lock washer clamps the module element against the wall plate and thus fixes it. The end of the concrete anchor can this an external thread and the lock washer a Having recess with internal thread, so that for clamping the module element the lock washer can be screwed onto the concrete anchor.

Due to the additional attachment of the module elements to the wall plate, a loosening of the module elements from the wall plate due to insufficient carrying capacity of the adhesive bond is excluded for module elements with a thickness greater than 20 cm or as a result of age-related decrease in the adhesive force of the adhesive. In particular, when using glued Holzweichfaserdämmelementen as modular elements, which have only a low tensile strength, resulting from the doweling also has the advantage that tearing of the module element and thus a release of the module element is prevented by the wall plate. When using concrete anchors as fasteners, the composite wall element is transportable by the bonding of the module elements on the wall plate, the concrete anchors after filling the cavity of the wall plate with concrete a permanent connection zwi between the module elements and the wall plate. Furthermore, there is the additional advantage that the module elements, the suction forces that can be caused by a wind flow along the free surface of the module elements Oberflä, safely absorb and consequently wind suction damage to a composite wall element used as a building exterior wall can be avoided.

The Length and / or height of module elements can be in Essentially the height and / or length of the wall plate made of formwork blocks. According to a preferred embodiment However, the module elements of the invention have a larger size Height as the wall disk on. There are only so many Rows of shuttering stones along the contact surface of the Module elements arranged so that the module elements in sections over the last row of shuttering stones and thus over the Extend wall disc out. This is over the wall disk Beyond extending portion of the module elements can in an advantageous Way as ceiling edge formwork for a manufacturable on site Ceiling plate to be used, which on the formwork blocks formed wall disk is arranged. The serving as Deckenrandschalung Section of the module elements for this purpose preferably has a projection from about 18 to 25 cm.

To the section of the wall element it can according to the Invention be provided that on at least one of the end faces of the wall element a plate-shaped stiffening element is arranged, which has recesses for the passage of concrete. The stiffening element is preferably made of a waterproof glued wood panel or a galvanized sheet metal rail, which on the cut surfaces of the shuttering blocks by gluing, nailing or screws are fastened. When editing an endless on the Support device producible wall element in lengths for example, 3 to 4 meters and then joining as well as gluing the individual wall element pieces on the Support device stiffens that between the cut surfaces the wall element pieces arranged stiffening the Combination of the individual wall element pieces, so that a delay and a bending of the combination of the wall element pieces is prevented in the longitudinal direction when the cavities filled the wall element pieces on the site with concrete become. By the openings provided in the stiffening elements are the cavities of the assembled wall element pieces connected with each other, so that after filling the cavities of the combination of composite wall elements Concrete creates a monolithic wall.

According to one another embodiment of the invention It can be provided that in the area provided for in the composite wall element Window or door opening no module elements and Formwork blocks are arranged along the mounting plane. The Size of the resulting opening in the wall element corresponds essentially to the installation dimensions a window or door element, wherein in the lintel area the window or door opening a corresponding Lintel stone is arranged. Such a fall formwork stone is known in the art, this being a length which is essentially the width of the door or door Window opening corresponds. The recesses and cavities the shuttering stones that are attached to the window or door opening be adjacent, with a soffit plate with at least one smooth surface, preferably a cementitious Wood fiber board or a waterproof glued multi-layer wood panel, locked. The fillable with concrete cavity of the invention produced Composite wall element is thereby in the range of window or Door opening sealed. For fixing the reveal plates on the open sides of the shuttering blocks these are preferably glued and nailed to the formwork blocks, with the nailing for example, with the help of a Schussapparates feasible is.

By closing the open sides of the shuttering stones a soffit plate with a smooth and even surface can when installing a window or door element the required sealing tapes directly on the reveal plate to be glued. To create a flat soffit surface is thus applying a Putzausgleichsschicht not required. Furthermore, the composite wall element through the reveal plates stiffened in the same way as in the arrangement of the aforementioned plate-shaped stiffening element.

For an arrangement of the window or door element in the region of the module elements, the reveal plate may have a width that substantially corresponds to the width of the shuttering blocks and the module elements. In other words, this means that the reveal plate protrudes beyond the width of the formwork blocks, so that the window or door element can be arranged at an arbitrary position between the inner and outer wall element surface. When using module elements made of a thermal insulation material, the window or door element can thus be arranged in the region of the insulating layer. This results in particular in Dämmschichtdicken of more than 20 cm, the advantage that the window or door element near the outer wall element surface, which is formed by the mounting plane associated surfaces of the module elements, can be arranged so that on the one hand constructive cold bridges and on the other hand Windverwirbelungen in the range of window or door openings are avoided.

to Production of a composite wall, which consists of at least a first and second wall element piece, it may be further be provided according to method steps, that the wall element after bonding of the module elements and the Formwork blocks cut into at least a first and second wall element piece becomes. After the cut of any length can be produced Composite wall element will be the wall element pieces to your Cut surfaces glued together. To help lift the Composite wall of the support a bending transversely and perpendicular to the wall level, will be along the bottom or the top row of formwork blocks a connection profile, in particular a connecting profile of galvanized sheet metal, arranged, which connects the individual wall element pieces together. The connection profile can in this case, for example, with the wall element pieces screwed and / or glued and preferably has one U-shaped cross section with a straight bridge and respectively a at the ends of the web at right angles arranged flange with the flanges being the lowest or highest row of shuttering stones embrace from the top or from the bottom. The U-shaped Connecting profile has round in the area of the straight bridge or oval openings for the concrete flow, making one at the bottom of the bottom row of shuttering stones arranged connection profile of the cavity of the wall element pieces connectable to a foundation or ceiling slab at the construction site is.

Next a U-shaped cross section is self-evident also conceivable that the connection profile an L- or T-shaped Cross-section, the at least two at right angles to each other arranged legs comprises. The first leg is doing on the side walls attached to the formwork blocks, with the second leg along a top or bottom of formwork blocks runs.

To the Arranging a window or door opening in the composite wall element it may be provided according to the invention, that between the cut surfaces of the first and second Wall element piece arranged a lintel and with each bonded to a portion of the wall element surfaces. The cut surfaces of the wall element pieces become thereby at least partially closed with a reveal plate, the closure preferably by nailing and gluing the soffit plate to the cut surfaces the shuttering stones takes place. In addition to closing the open cut surfaces for shuttering the cavity of the Wall element pieces support the reveal plates with their upper edges in addition to the crash element.

Around a deflection of the wall element pieces and lintel element formed composite wall element can be prevented along the top row of formwork blocks and the lintel element a connection profile be attached, which the wall element pieces with the Crash element connects. The connection profile can in this case, for example bolted to the wall element pieces and the lintel element and / or glued. The connection profile is preferably from a galvanized sheet metal with a U-shaped cross section, but also another cross-sectional shape is conceivable that at least comprise two legs arranged at right angles to each other. Of the first leg is on the side walls of formwork blocks and lintel elements fastened, wherein the second leg along a Top of formwork blocks and the lintel runs and thus supports them.

The lintel is preferably a known from the prior art, fillable with concrete U-shaped lintel element with cavity, which consists of the same material as the shuttering blocks or waterproof glued multi-layer panels and may have disposed on the outside of thermal insulation. The thermal insulation can be glued in the form of an insulating element on the lintel element. For the removal of wall, lintel or ceiling loads, the lintel element further comprises a reinforcement, which is enclosed by the concrete after filling with it. According to a further embodiment of the invention, the lintel may consist of U-shaped shuttering blocks glued together, wherein the reinforcement arranged in the lumen of the lintel element extends over the length of the lintel element and is fastened to at least one of the side walls of the shuttering blocks. By attaching the reinforcement to the shuttering stones of the lintel element, the bending stiffness of the U-shaped formwork blocks glued together is increased, so that the lintel element does not bend when filling the cavity with concrete. For example, a lattice girder can be used for the reinforcement of the lintel element made of shuttering or waterproof glued multi-layer panels, which can be produced in great length and is cut to the appropriate measure 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 lintel element. When filling the lintel with Concrete forces acting on the shuttering blocks or the waterproof glued multi-layer panels forces on the arranged on the side or bottom wall of the lintel fasteners, the spacers and the lattice girder are removed, whereby bending of the lintel element is avoided.

to Forming a window opening arranged within the wall plane it may further be provided according to the invention be that a parapet element between the cut surfaces the wall element pieces is arranged. That parapet element is glued to the cut surfaces, which are not are closed by a soffit plate. To the parapet element to connect with the Wandelementstücken, is the parapet element with the above-described along the underside of the wall element pieces extending connecting profile mechanically connected. Like the wall element pieces is also the parapet element from side and / or one above the other arranged shuttering bricks, their respective cavities extending in a vertical and horizontal direction form common cavity. Preferably for the Production of the parapet element the same shuttering stones as used for making the wall plate. By eleven gluing the front sides of the parapet element with the Cut surfaces of the wall element pieces are the Cavities of the wall element pieces and the parapet element connected with each other.

The Parapet element is preferably like the wall element by arranging and mutual bonding of modular elements and Formwork blocks produced along a mounting plane. in this connection can the formwork blocks and the module or the elements the parapet element, for example, directly between the Intersecting surfaces of the wall element pieces arranged become. On the other hand, it is also possible, the parapet element prefabricated as an endless wall on the support device and after bonding formwork blocks and modular elements to the appropriate length to cut. The length of the Parapet element results from the distance between the cut surfaces of the wall element pieces, wherein the distance depends on the installation dimensions of the window element is.

To a further embodiment of the invention The method can be the construction period of a prepared according to the invention Composite wall elements erected building thereby continued be shortened when on the outer elements formed by the module elements Wall element surface applied an exterior plaster base becomes. It has proven to be particularly advantageous a mineral bonded adhesive and reinforcing mortar, which is reinforced by a reinforcing fabric, on the Wear surface of the module elements. The order of the Finishing plaster can be factory-installed as well as after-factory the bonding of adjacent composite wall elements the construction site.

According to one further process step of the invention may be on the inner Wall element surface an abrasion-resistant interior plaster, in particular a Faser-Armierungsputzgrund be applied. The order of Interior plaster layer takes place at least over a section the inner wall element surface away. By the possibility the prefabrication of the wall element is the interior plaster, for example the wall element surface is sprayed on. Especially in seasons with increased precipitation probability The interior plaster while additives are added, which reduce the moisture sensitivity of the plaster. In this way is the provided with a plaster lining composite wall element on the Construction site transportable, without the interior plaster by mechanical or weather-related stresses affected becomes.

Due to the possibility of the climatic conditions, such. B. humidity and air temperature, at the place of manufacture of the composite wall element to control, an interior or exterior plaster with a good bond to the material of the modular elements or the shuttering stones can be produced, wherein. Drying stresses and associated cracks in the plaster are avoidable. In order to connect their respective plaster layers to one another in the joint area of adjoining wall elements, a plaster layer with a thickness which is less than in the remaining area of the wall element area can be applied in a strip-shaped edge area of the wall element areas. After a juxtaposition of two adjacent composite wall elements can be aligned in this way in the strip-shaped edge regions, the plaster layer of lesser thickness to the thickness of the plaster layer of the remaining wall element surface. To avoid cracks in the plaster in the joints of two interconnected composite wall elements, it may also be provided that the adjacent strip-shaped edge regions of the composite wall elements and thus the butt joint before the application of another layer of plaster covered with a strip of reinforcing fabric the.
