Description

The The invention relates to a method for producing a transportable prefabricated building wall element made of shuttering stones, in particular wood screed stones, as well as a building wall element, which was produced 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 of claim 1 and 31 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 process step plate-shaped insulating elements arranged along a mounting plane of a support device. The insulation elements are in this case with one of their levels Exterior surfaces flush with the mounting plane at. The in this way along the mounting plane over- and juxtaposed insulating elements are in the Art arranged that the insulation 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 several insulating elements along the mounting plane, it can be provided that the insulating elements are connected to one another at their end faces, in particular adhesively bonded. The insulating elements are preferably thermal insulation boards, in particular Holzweichfaserdämmplatten whose outer surfaces angeord essentially flat and plane-parallel to each other are net.

To the creation of a first wall section of insulation elements become shuttering stones in a second process step, in particular Timber shears, along the flat outer surface the insulation elements in superimposed rows arranged. 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 the insulating elements and on the top, bottom and front sides applied an adhesive from adjacent formwork bricks, so that the formwork stones both together and with the Insulating elements are glued. As an adhesive is this preferably an adhesive adapted to the insulating elements, For example, PUR foam when using insulation boards Styrofoam, polyurethane or polystyrene rigid foam, used. The Adhesive can do this with a spray gun on the adhesive surfaces the formwork blocks and insulation elements are applied. Furthermore, it may be provided that for the gluing Kle of insulating elements and shuttering stones as well as for the bonding of the formwork blocks each one for this purpose suitable adhesive is used.

By the arrangement of the insulating elements on the mounting plane as well the arrangement of formwork blocks along the flat outer surface the insulating elements creates an endless wall in the thermal insulation composite system, both the flat exterior facing the mounting plane Wall element surface as well as a plane remote from the mounting plane having inner wall element surface, which from the side walls formwork blocks are formed. The flat wall element surfaces of the building wall element are in this case with a high dimensional accuracy can be produced so that when applying an exterior or interior wall plaster a compensation of unevenness is eliminated and thus less I require cleaning material.

To the production of such a composite wall of shuttering stones and dam 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 Building wall element on the bottom supports, 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 Plane of the outer wall element surface, adjustable, whereby the wall element can also be mitred is. When assembling two building wall elements, z. B. at an angle of 90 ° for the corner of a building, this results in the advantage that at a cutting angle of 45 °, the building wall elements at their abutting surfaces only flush with each other must be glued. By the flush bonding The building wall elements will be in vertical and horizontally extending cavities of the wall slices connected with each other. After pouring together connected cavities of the two building wall elements with concrete, especially precast concrete, these are both over the glue joint in the corner area as well as over in the voids resulting concrete skeleton connected to each other. Furthermore, there is the advantage that the abutting surfaces of two adjoining building wall elements produced according to the invention have a large adhesive surface and thus a Ensures good bond between the building wall elements becomes. In addition, by the flush connection of the Building wall elements an emergence of thermal bridges in the area of the impact is avoided. That according to the Invention produced building wall element can be used as Exterior wall to be used for a building.

By an off-site, d. H. factory Prefabrication of the building wall element accounts for the Construction site necessary for attaching insulation elements Scaffolding. The life of scaffolding shortened thus on the for the application of the exterior plaster required time span. In addition, it exists due the prefabrication of the advantage that the insulation elements in the manufacturing plant of the invention Wall elements are easier to handle than on a construction site, which also usable insulation elements in large formats are. Furthermore, compared to an erection of a building wall Shuttering stones and insulation elements on the construction site of the Influence of the weather of only minor importance, since the adhesive joints between the formwork blocks and the insulation elements independent of weather conditions can be produced in production halls. This will be an equal lasting quality and high dimensional accuracy the building wall elements guaranteed.

According to the invention it also conceivable, of course, instead of the insulating elements the shuttering blocks in a first step along the Assembly level to be arranged, with the insulating elements on the Sides of the formwork blocks are glued, which the mounting plane are averted.

additionally for bonding can according to one embodiment the inventive method, the insulating elements and the wall plate formed from formwork bricks Fasteners are connected together. The connection the insulating elements with the wall plate made of shuttering stones can be done for example by concrete anchors, which in the Extend cavity of the wall plate into it. After bonding the insulation elements and the shuttering blocks, the concrete anchor is thereby from the outer Wall element surface forth through the insulating element therethrough screwed into the side wall of a shuttering block. 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 Insulating element attached to the wall plate. on the other hand It is also conceivable that when walling the shuttering stones Concrete anchor is inserted into the glue joint, with the concrete anchor in the direction of the mounting plane through the insulation elements must be plugged. After gluing of insulation elements and Shuttering can be applied to the end of the concrete anchor, which is extending through the insulating element, a lock washer be attached. The lock washer clamps the insulating element against the wall plate and thus fixes it. The end of the concrete anchor this can be an external thread and the lock washer have a recess with internal thread, so that for clamping of the insulating element, the locking washer on the concrete anchor can be screwed on.

By the additional attachment of the insulation elements the wall plate is a release of the insulation elements due to insufficient carrying capacity of the adhesive bond for insulation elements with a thickness greater than 20 cm or as a result of aging due to the Adhesive strength of the adhesive excluded. Especially at the Use of bonded wood soft fiber insulation elements, which have only a low tensile strength, results from the doweling also has the advantage of tearing open the insulating element and thus a release of the insulating element is prevented by the wall plate. When using concrete anchors as a fastener the building wall element is through the bonding of the insulation elements on the wall plate transportable, the concrete anchors after filling the cavity the wall panel with concrete a permanent connection between the Manufacture insulating elements and the wall plate. Continue to exist by the additional attachment the advantage that the Dämmelemente the suction forces caused by a wind flow along the free surfaces of the insulation elements can safely build up and consequently wind suction damages be avoided on the building wall element.

The Length and / or height of the insulation elements can be essentially the height and / or length of the Corresponding wall plate made of formwork blocks. After a preferred Embodiment of the invention, the insulating elements however, a greater height than the wall plate on. For this, only so many rows of formwork bricks along arranged the contact surface of the insulating elements, so that the insulation 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 insulating elements can in Advantageously, as ceiling edge formwork for a on the building site to be used ceiling plate are used, which on the wall plate formed of shuttering stones is arranged. The serving as Deckenrandschalung section of the insulating elements For this purpose, preferably has a supernatant of about 18 to 25 cm up.

According to one another embodiment of the invention Method may be provided that in the area of a building wall element provided window or door opening no insulation elements and shuttering blocks are arranged along the mounting plane. The size of the resulting opening in the wall element corresponds essentially to the mounting dimensions of a Window or door element, wherein in the lintel area of the window or door opening a corresponding fall formwork stone is arranged. Such a fall formwork stone is out of the state known in the art, this having a length, the essentially the width of the door or window opening equivalent. The recesses and cavities of the shuttering stones, adjacent to the window or door opening, come with a soffit plate with a smooth surface, preferably a cement-bonded wood fiber board, sealed. The fillable with concrete cavity of the invention produced Building wall element is thereby in the range of window or door opening sealed. To attach the Reveal panels on the open sides of formwork blocks these preferably glued and nailed to the formwork blocks, the nailing, for example, using a Schussapparates is feasible.

By closing the open sides of the shuttering blocks with a reveal plate with smoother and flat surface can be glued directly to the soffit plate when installing a window or door element, the required sealing strips. To create a level reveal surface thus applying a Putzausgleichsschicht is not required.

To the Arranging a window or door opening in the building wall element It may be after further process steps according to the invention be provided that the wall element after bonding the insulation elements and the shuttering blocks in a first and second wall element piece is cut. The cut surfaces of the wall element pieces are then at least partially with a Sealing plate closed, the closure preferably by nailing and gluing the soffit plate to the cut surfaces the shuttering stones takes place. After closing will between the first and the second wall element piece Lintel arranged and each with a portion of the wall element surfaces glued, which is not closed by one of the reveal plates is. In addition to closing the open cut surfaces support the shuttering of the cavity of the wall element pieces the soffit panels with their upper edges additionally the lintel element from. To a deflection of the wall element pieces and lintel element formed building wall element in the direction of the building wall level and transverse to prevent this, are along the top and the lowest rows of shuttering stones at least one upper one attached first and a lower second connection angle. Of the Upper and lower connection angles extend along this the top and bottom row of shuttering stones and places an upper and lower end of the building wall element In addition to the attachment to the first and second wall element piece the upper first connection angle is also at the lintel element attached so that it is supported by the upper first connection angle becomes. The connection angles can be, for example, here bolted to the wall element pieces and / or the lintel element and / or glued. Preferably, the connection angles exist from a galvanized L-shaped or T-shaped metal profile, the comprises two legs arranged at right angles to each other. The first leg is on the side walls of the shuttering stones and lintel elements fastened, wherein the second leg along a Top or bottom of the shuttering blocks or the lintel element runs and thus supports them.

at the lintel is preferably one out of the state the technology known, fillable with concrete U-shaped Lintel with cavity, which is made of the same material as the Formwork blocks exists and one arranged on the outside Thermal insulation may have. The thermal insulation can in the form of an insulating element on the lintel element be glued. For removing wall loads includes the lintel Continue a reinforcement after filling with concrete is enclosed by this. According to another inventive embodiment can the lintel made of U-shaped glued together Formwork stones exist, wherein the cavity in the lintel element arranged reinforcement over the length of the Lintel extends away and on at least one of the side walls the formwork blocks is attached. By attaching the reinforcement on the shuttering stones of the lintel is the flexural rigidity the bonded U-shaped formwork blocks, so that the lintel when filling the cavity not bent with concrete. For example, for the reinforcement a grid ear carrier can be used in large Length is produced and on the suitable for the lintel element Measure is cut. The grid pipe carrier has preferably a triangular or quadrangular cross-sectional shape, wherein one of the sides of the grid pipe support with the side walls the formwork blocks is screwed. When filling the glued U-shaped formwork blocks with concrete The forces acting on the shuttering stones are transferred over removed the screw connection and the grid tube carrier, whereby a deflection 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 an additional Connection of the parapet element to the wall element pieces manufacture, the parapet element with the lower second Connecting angle mechanically connected. Like the wall element pieces if the parapet element also consists of side by side and / or one above the other their respective cavities are in vertical and form a horizontal direction extending common cavity. Preferably, for the production of the parapet element the same formwork blocks as for the production of the Wall washer used. By 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 lower second connection angle connects in this case the parapet element with the wall element pieces and also cuts it off.

The parapet element is preferably as the wall element produced by arranging and mutual bonding of insulating elements and shuttering blocks along a mounting plane. Here, the formwork bricks and the or the insulating elements of the parapet element can be arranged for example directly between the cut surfaces of the wall element pieces. On the other hand, it is also possible to prefabricate the parapet element as the wall element as an endless wall and to cut after the bonding of formwork blocks and insulation elements to the appropriate length. The length of the parapet element results here from the distance between the cut surfaces of the wall element pieces, wherein the distance depends on the installation dimensions of the window element.

By the section of the wall element in at least two pieces and placing a lintel between their cut surfaces is a building wall element in a simple and inexpensive way produced, which prefabricated transported to a construction site can be and includes a window and / or door element. By attaching a first and second connection angle along the wall element pieces and the lintel element or Parapet element has the building wall element thus formed a great bending stiffness in the direction of the wall plane as also across to it. This results in the possibility that Window and / or door element already at the place of prefabrication to integrate into the building wall element without having to Transport of the building wall element warps and deformations occur the glass surfaces receiving only slight compressive stresses destroy the window and / or door element. Due to the rectilinear edge of the lower second connection angle this also serves to align the building wall element on the site.

Next The increase in wall stiffness can at least one the connection angle additionally as a cleaning stop for an inner wall plaster layer to be applied to the inner wall element surface which. For this purpose, the at least one connection angle to an impact bar at least along the length of the at least first and second wall element pieces extends and extending from the inner wall element surface. The Stop bar in this case has a width equal to the thickness of the applied Plaster layer corresponds. In this way, when plastering the inner wall element surface a uniform Thick plaster layer are applied, the required minimum thickness equivalent. The plaster stop additionally provides a trailing edge the plaster layer, which is straight and even along the upper and / or lower row of shuttering stones.

According to the Invention may be below a window opening arranged formwork blocks on the top with a reveal plate to be introverted. Like the other soffit panels, this too Reveal plate has a smooth surface and facilitates thus the attachment of sealing strips and the installation a window element. To fill the below to simplify the window opening arranged shuttering blocks, has the soffit plate here openings on, through the concrete in the interconnected cavities of formwork blocks can be filled. In this way, the introduction takes place of concrete in the arranged below the window opening Shuttering stones thus both from the top of the building wall element as well as through the cavities of the window opening adjacent wall element pieces, which with the cavities the shuttering stones arranged below the window opening are connected.

To a further embodiment of the invention The method can be the construction period of a prepared according to the invention Building wall elements continue to build the building be shortened by when on the of the insulating elements formed outer wall element surface Exterior plaster base is applied. Here it has as particularly advantageous, a mineral bound Adhesive and reinforcing mortar, which passes through a reinforcing fabric is reinforced, on the surface of the insulating elements apply. The order of the top coat can be both factory in Production halls as well as after the bonding of adjoining ones Building wall elements made on the site.

Instead of the arrangement of insulating elements plate-shaped lining elements are arranged along the mounting plane of the support device according to a further embodiment of the invention. The plate-shaped cladding elements form a planar Anstellfläche, which faces away from the mounting plane and can be arranged in rows on the shuttering blocks. 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 formed, which has flat wall element surfaces. The cladding element may in this case be, for example, a carrier plate with tiles arranged thereon or a plate made of plasterboard or gypsum fiber, which is glued to the formwork blocks by means of filler adhesive. By replacing the insulation elements against the cladding elements, the building wall element produced in this way can be used as an interior wall element in the construction of a building. Due to the Composite construction of cladding elements and formwork blocks, the building wall element has a high bending stiffness in the directions of the wall plane and perpendicular thereto. When using the Füllklebers for the connection of the cladding elements and the shuttering stones results in particular in Holzspanschalungssteinen the advantage that the existing pores and depressions in the surfaces of the shuttering stones are filled by the filling adhesive, creating a substantially air-impermeable building wall element. The building wall element is thus suitable for the construction of a building with a largely airtight building envelope. In the bonding of plasterboard or gypsum fiber boards, the sound insulation of the building wall element is further improved, the plasterboard or gypsum fiber boards record as a soft shell the sound waves.

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 sprayed onto the wall element surface. In particular in Seasons with increased precipitation probability You can add additives to the interior plaster which reduce the moisture sensitivity of the plaster. On This is the building wall element provided with a plaster transportable to the construction site, without the interior plaster through mechanical or weather-related stresses affected is pulled.

As a result the possibility of climatic conditions such. B. Humidity and air temperature, at the place of manufacture of the building wall element to control, is still an interior and exterior plaster with a good bond to the material of the insulating elements or the shuttering stones can be produced. As a result of controllable environmental conditions are Drying stresses and associated cracks in the plaster avoidable. To be in the joint area of adjacent wall elements their respective plaster layers to connect with each other, can in a strip-shaped edge region of the wall element surfaces Apply a layer of plaster with a thickness that is lower is than in the remaining area of the wall element surface. To a joining together of two adjacent building wall elements can in this way in the strip-shaped edge areas the plaster layer of lesser thickness to the thickness of the plaster layer of remaining wall element surface to be aligned. To avoid Cracking the plaster in the joints of two interconnected building wall elements can It should also be provided that the adjacent strip-shaped Edge areas of the building wall elements before the order of a another layer of plaster covered with a strip of reinforcing fabric become.

According to the Invention can also at least in addition to the use of a wet plaster a drywall interior plaster on the inner wall element surface be applied. This is done on the inner wall element surface at least one plate-shaped cladding element attached, which is preferably at least one glued plasterboard or gypsum fiber board. For the bonding of at least a covering element is a layer of adhesive on the Sidewalls of shuttering blocks, which form the inner wall element surface form, applied. This is preferably a Filler glue that pores and depressions in the sidewalls the formwork blocks closes or fills and thus reduces the air permeability of the building wall element. To slipping of the plate-shaped paneling element along the inner wall element surface from drying out of the adhesive to prevent, it may further be provided that the at least one cladding element after gluing in addition is still nailed or clamped with the wall plate of formwork blocks. This results in the advantage that the inventively produced Building wall element immediately after the gluing of the or the cladding elements can be further processed and transportable is.

to further shortening of the establishment of a Building required construction time on the site can it according to another invention Process step be provided that at least one installation line on the insulating wall facing away from the inner wall element surface is attached. In the installation line, this may be For example, to a heating pipe, an electrical supply line, a water pipe or a ventilation installation with act an associated ventilation element.

According to a further embodiment of the invention, the at least one installation line can be bonded directly to the side walls of the shuttering blocks, which form the inner wall element surface. The bonding of the at least one installation line can be done with the same adhesive, which was previously used for the bonding of formwork bricks. The installation line is preferably arranged under the interior plaster, so that the plaster application only after the attachment of the installation line on the inside Ren wall element surface takes place. Due to the arrangement of the building wall element on the support device, the inner wall element surface for the attachment of the installation line is easily accessible, the necessary for the production of wall plate scaffolds are also suitable for mounting the installation line.

When inventive alternative to direct bonding However, the installation line can also be provided that one or more support rails with recesses on the inner Wall element surface attached, in particular glued, in which the at least one installation line inserted, in particular glued or pinched.
