Description

 Interior construction and method for its implementation

The present invention relates to a method for carrying out an interior work in an existing shell and a Innenausbau produced by such a method.

For this purpose, various possibilities are already known from the prior art. A major problem in the implementation or production of an interior - in an existing shell concerns the fact that a shell often does not follow exactly the dimensions given in the original blueprint and that possibly all or individual walls or other components of the shell of a Plan deviating course - in horizontal and / or vertical direction - have or are not positioned exactly where they should actually stand according to the blueprint. In the context of the present invention

shell work to be dismantled may be e.g. to a new building or to a -. gutted - Old building act, the latter possibly no planning documents are available. Also, the bottom surface of a shell often does not exactly in a horizontal plane, including before performing an interior or as part of the same usually first by means of a screed a (more or less) horizontal bottom surface is created.

In view of the above dimensional inaccuracies of a bodyshell compared to the planning documents relevant in this respect and the fault tolerances allowed for standard designs (such as the relevant German industrial standards (DIN) or the corresponding International Standards (ISO)) for interior fittings must be considered within the framework of the

Carrying out an interior construction, which comprises at least one inner wall to be constructed inside the interior to be built out, the space dimension existing after erection of the inner wall is always to be resumed for further interior construction steps, if subsequently continued with high precision. should be processed. Correspondingly, then already pre-fabricated planning documents eg for interior fittings such as built-in wardrobes or fitted kitchens or for the heating,

Re-adapt sanitary or electrical installation and carry out according to the new dimensions. A pre-production of the components required for this is therefore not possible or only after measuring the already partially created interior.

This is particularly critical in large construction projects, where the interior would like to be carried out by companies that have their headquarters away from the construction site. This not only results in high travel costs for the companies carrying out the interior work, but also a significant time delay for the interior fittings.

Also, the planning of the interior design is often based on the planning documents of the shell, whereby in the context of the construction of interior walls belonging to the interior walls is always a high degree of inaccuracy, where a special interior wall can now be built exactly. This can often only be decided on site or after consultation with the client, with the additional consequence that certain room dimensions can still change significantly in comparison to the (pre) planning.

Furthermore, there is a need for a new concept for interior fittings, especially with larger and international construction projects (eg larger office buildings and skyscrapers), with which the respective owner / tenant of a building use unit only late in the construction project, often long after Completion of the shell is to be made possible to plan and implement in the shortest possible time as flexible as possible spatial planning for interior design. Furthermore, increasingly higher demands are placed on the noise and heat insulation. As well as required for insulation components of the interior design as possible with a high dimensional accuracy have to be produced, also arise in this regard, the aforementioned problems.

Another problem relates to the fact that previous interior fittings usually have to be carried out by high-quality trained personnel, as often a sophisticated adaptation of prefabricated elements must be made to the locally taken dimensions of the spaces to be built. Overall, the interior of Rohbauten thus represents a very expensive part of a construction project.

DE 198 34 616 A1 discloses a method for producing a building or for producing wall elements of a building, in which the entire building is planned by means of a CAD-CIM system and wall elements are produced with the aid of a production robot. An indication of how an interior work could be carried out in an existing shell, but can not be found in said document.

Against this background, it is the object of the present invention to provide a method for carrying out interior work in an already existing shell, which overcomes the above-mentioned disadvantages and meets high precision requirements. In particular, a universally applicable method should be provided, in which a tailor-made, in the calculations of its components to be calculated in advance

Interior work can be carried out and erected in the simplest possible way. Furthermore, a correspondingly produced interior design should be provided. Further advantages of the invention and its preferred developments will become apparent from the following description.

The above object is achieved by providing a method for performing an interior work in an existing shell according to claim 1 and an interior structure according to claim 13. The method according to the invention comprises the following steps:

(A) Measuring the interior of the shell with a resolution in the millimeter range and creating a three-dimensional CAD model of the interior (the shell)

(B) Creating a suitable space planning for interior design and entering the spatial planning data in the CAD model, the interior at least one to be established within the shell interior wall and a positioning aid for the

 contains at least one inner wall serving construction structure, wherein the inner wall comprises at least one wall element, which by means of a

 Positioning means can be accurately positioned on the existing of a plurality of structural structural elements construction structure, wherein the positioning means comprises at least one positioning element which is formed on the construction structure and / or on the wall element

(C) calculating a suitable geometry of the structural structure elements forming the structural structure and the geometry of the at least one wall element from the data of the CAD model, wherein the geometry of the structural structural elements and / or the at least one wall element determines the exact location and geometry of the at least one positioning element to be formed thereon includes

(D) producing the at least one wall element and the structural structure elements forming the construction structure in the geometry calculated according to step (C), wherein the at least one positioning element is introduced into the relevant wall element and / or structural element by means of a computer-aided machining step (E) assembly of the interior under the correct position mounting of the structural structure elements within the shell and positionally correct positioning of the at least one wall element using the positioning means.

The method according to the invention combines a multitude of advantages which, in particular, significantly accelerate or facilitate the process sequence in the production and assembly of an interior fitting compared with the prior art, and permit a high degree of precision. Before, however, the decisive advantages of the method according to the invention will be discussed, let us first give a few general comments and explanations concerning the method steps according to the invention:

Insofar as in step (A) the resolution or measurement accuracy in the context of the measurement of the interior is specified as "in the millimeter range", this advantageously means an accuracy with a fault tolerance of only a few millimeters to that for the purpose of planning and implementation of the interior to be measured (inside) aße of the entire interior to be built. For this purpose, preference is given to using a suitable measuring device with which the (three-dimensional) measurement of the interior can be largely automated. Suitable measuring devices, e.g. 3D (laser) scanners are known in the art. Preferably, the measurement is achieved using a transportable 3D scanner to be set up at a suitable location within the shell, whose resolution in the distance measurement of the measurement points of the interior is a measurement deviation of less than 5 mm per 10 meters length, again preferably a measurement deviation guaranteed under 3mm or even under 1mm per 10 meters in length.

3D (laser) scanner with the above-mentioned properties for measuring accuracy, which is usually carried out by means of a moving Lens mirror assembly or a movable prism deflected laser beam and the evaluation of its diffuse reflection based on any surface are commercially available. To carry out a measuring operation, the relevant (3D) scanner is set up at a suitable location within the space to be built, from where he - possibly completely automatically - the surrounding space, ie the interior of the dismantled shell, missing. Of course, in the context of method step (A), the (three-dimensional) measurement of the interior does not have to be completed with a single measuring operation. On the contrary, it can offer itself-for example to increase the measuring accuracy-or, depending on the geometry of the interior if necessary, it may also be necessary to carry out a plurality of measurements from different installation locations for the 3D scanner.

Decisive within the scope of the invention is furthermore that in a concluding process step the measurement data obtained with the required accuracy are combined in a data processing system to form a three-dimensional CAD model of the shell to be removed, whereby common ones

mathematical models are used (e.g., the method of interpolation to compute a plot from a plurality of measurement points on the area concerned).

In this case, care should preferably be taken that the CAD model obtained also contains information on the exact spatial position of the measured surfaces relative to the vertical and horizontal, for which purpose e.g. the scanner can provide appropriate information by means of a spatial position sensor. Alternatively, a corresponding information can be obtained under measurement suitable to be selected reference points on the shell, the exact relative position in the horizontal and / or vertical direction is known or measured separately.

In accordance with step (B) of the method according to the invention, a suitable interior planning for the interior construction is then carried out. provides. These are firstly the room layout of the interior work to be carried out which is desired by the client or specified by the architect, which comprises at least one interior wall to be constructed within the interior of the shell in the most precise manner possible with the data relevant to the desired course and the geometry of the inside wall. The data relating to the interior design or its spatial planning data are then entered into the CAD model, whereby the exact course of the at least one inside wall to build inner wall and its geometry (in particular their width) are specified.

In this case, it is provided that the at least one inner wall to be constructed has at least one wall element to be positioned correctly to a construction structure. Under wall element is to understand a frame-like or areal structure formed, which predetermines or spans the usually exactly vertical plane at least one side of the inner wall to be built. It can be assumed in the context of the invention, for example, from a total pre-assembled inner wall. On the other hand, however, it may also be advantageous for the inner wall to have two wall elements which are oriented parallel to one another and, if necessary, to be mounted separately, which predetermine the two different side surfaces of the inner wall and leave space in their intermediate space for other installations. The above-mentioned construction structure serves - as an important part of the interior design - as a positioning aid for the at least one inner wall and consists for this purpose advantageously of a plurality of construction elements.

In the calculation steps of step (C), which are preferably carried out by means of a data processing system with access to the data of the CAD model, a suitable geometry of the individual structural structure elements forming the construction structure and the geometry of the at least one wall element required for the interior work are then calculated. Thereby the calculation finds on the basis of the data of the CAD model, ie using the exact spatial planning data, where additional data can be used in addition. The additional data can be, for example, specifiable standard dimensions / standard geometries of the components to be used for the interior construction (wall elements, structural elements, etc.) or the positioning elements to be formed thereon. Furthermore, manual inputs to be entered (eg regarding the position of the positioning means or - local or global deviations from standard dimensions) may also be taken into consideration.

The construction structure serving as a positioning aid for the at least one wall element or, as a rule, for a plurality of wall elements preferably covers the entire interior space to be constructed or the interior work to be constructed therein in the sense of a grid. The geometry of the interior space measured in step (A) and the position of the at least one inner wall or of the at least one wall element predetermined according to spatial planning thus provide the boundary conditions for a suitable geometry of the construction structure, so that their geometry (or the geometry of the individual, the construction structure-forming structural elements) can be calculated using the data of the CAD model. Advantageously, the dimensions of the individual construction structure elements are standardized, with the result that only the geometry of individual construction structure elements in the edge area of the interior to be removed (deviating from the standard geometry) must be adapted to the measured space geometry in accordance with the CAD model. Of course, there are other special features in the

Geometry of individual structural elements or a deviation from the standard geometry where to construct an inner wall and is provided in a suitable manner at least one relevant positioning element.

The construction structure may advantageously be provided on the floor or on the cover side, it being within the scope of the invention may also be advantageous to provide a total of two -different or identically constructed - construction structures, one of which laterally one and the other cover side is to install in the shell and thus a positionally correct positioning of the wall elements both bottom and top side in a simple manner can be ensured. The floor or ceiling-side cross-sectional area (in a horizontal plane) of the interior of the shell so that in this case the (outer) dimensions of a suitable structural structure before, for the construction structure, for example, provided a predetermined distance to lateral (or inner) boundary walls of the shell can be. A ceiling-side construction structure can then also serve, for example, as a positioning aid (or assembly structure) for an interior ceiling to be fitted or suspended between the interior walls.

The construction structure may be, for example, a frame-like structure, wherein - which is explained in more detail below on the basis of a preferred embodiment of the invention - in particular also a plate-like design of the construction structure is advantageous. In the context of the present invention, it is merely essential to the invention that the design structure is predetermined or calculated (and manufactured) in its geometry in such a way that it fulfills its central function as positioning aid for the at least one wall element within the interior to be constructed.

For this purpose, it must permit a positionally correct positioning of the wall element by means of suitable positioning means, for which purpose a suitable positioning element is to be formed on the construction structure itself and / or on the wall element.

A positioning element may be designed, for example, in the form of (at least) one bore to be positioned precisely or (at least) one groove to be positioned precisely. So, NEN, for example, at a suitable point of the construction structure, at which this advantageously comes to the wall element to the plant, a first bore (or groove) and in the wall element at the location corresponding thereto a second bore

(or groove) are provided, which - in the correct position positioning of the wall element to the structural structure - aligned with the first bore or groove. Together with an external pin or pin to be inserted in both holes

(Or a to be introduced in both grooves spring (strip) for producing a tongue and groove joint) can then be formed a suitable positioning means. Instead of using external pins or spring strips, a pin cooperating with a bore or a tongue cooperating with a groove can be formed on the respective other component, for which purpose preference is likewise given to a computer-aided machining method which ensures the required precision. Of course, a plurality of positioning means may be provided for positionally correct positioning of a wall element, in particular over its length.

In general, any means can be considered as a positioning means with which a positive connection between wall element and construction structure (element) can be produced for the purpose of positional positioning. The position and geometry of the at least one positioning element, which brings about a positive fit with a (separate or formed on the other component) counterpart, in the wall element or in the relevant structural element structure is within the - advantageously computer-aided and automatic - calculation of the geometry of the component in question is considered and thus stands for the subsequent manufacturing or manufacturing step (D) - preferably as part of a computer-readable record for each component to be produced (wall element, structural element, etc.) - available. For this purpose, the geometries calculated in step (B) can be seen in corresponding computer-readable data sets for the individual To enter or transfer components. Advantageously, these can be added to the existing CAD model.

Then, the individual components (structural elements, wall elements, etc.) can be prepared in a precise manner based on the geometry calculated in step (C), of course, in the case of the use of standardized raw elements for the components in question, only for those components to make an adjustment, the loud - computer data set or CAD model - should deviate from the standard form, eg by incorporating a positioning element at specific points by means of a computer-aided processing step. A computer-aided processing step, which makes use of a computer-readable data set for carrying out the relevant processing operation, is particularly exact. Such a machining step or machining method may be, in particular, a computer-aided drilling or a CNC milling method, for which purpose the components concerned, at least in the areas to be machined, advantageously consist of a suitably machinable material, e.g. a CNC millable material such as Wood or metal, can be made. In this case, a corresponding machine is used, which recognizes the external geometry of the component to be machined (if necessary) and - in comparison with the calculated (nominal) geometry - correct position brings the relevant positioning element (eg bore, groove, etc), namely, on the location resulting from a computer data record for the relevant component or from the CAD model containing this data.

In the context of the introduction of the at least one positioning element in the or the relevant components is preferably an accuracy of less than 1 mm, more preferably less than 0.5 mm or even 0.1 mm, to ensure the exact location and spatial extent of the respective positioning element. Also the actual geometry of the Further (standard) components to be produced in the context of the invention should advantageously have a correspondingly small deviation from the geometry calculated for the relevant component.

Finally, in accordance with step (E), the interior fitting is mounted in the interior of the shell, wherein first the construction structure (of the plurality of structural elements) to mount correctly within the shell and then the at least one wall element for this position correctly positioned (using the at least one - Positioning means comprising at least one positioning element).

The positionally correct positioning of the construction structure or of the construction structural elements forming it within the shell is advantageously ensured by predetermining the exact position or orientation of at least one construction structure element relative to at least two suitable reference points within the shell and adhering to the assembly. The exact positioning of the further structural structural elements then results advantageously from their positionally to be ensured connection to the or each adjacent structural structural elements, which are already mounted in the correct position. For this purpose, preferably two adjacent structural structural elements by means of at least one

Connecting means or positioning means to connect, which in turn advantageously comprises at least one positioning element, in the context of the production of the relevant structural structure elements by means of a

computer-assisted machining step in at least one (preferably both) of the two structural elements is introduced. This may, as already mentioned elsewhere, for example, to holes or grooves for the production of a (positive) plug-in, for which, if necessary. Separate or on each other's structural ment trained pins, pins or springs (for a tongue and groove connection) are provided.

Preferably, at least one structural structural element, after its positional positioning within the shell, is permanently connected to the floor, ceiling or side wall of the shell using a suitable bonding means (such as a screw).

The inventive method thus has the notable advantage that under three-dimensional measurement of the interior of a shell first a 3D CAD model thereof is created, which then as a starting point for the further process steps of spatial planning, the calculation of the geometry of the components to be used and the Production of said components is used. This makes it advantageous to build the entire interior of vorzufertigenden individual components, the right to use because of the use of a computer-aided processing method in their connection areas with the shell or with each other by means of precisely producible positioning elements, i. positionally accurate within the interior are mountable.

The final result is an exceptionally precise interior design, which can be planned and assembled in a final assembly step - without any need for re-measurements or adjustments to the subsequent steps - something that does not even require a particularly well-trained staff. Because by a corresponding assembly instructions in which e.g. the individual components (structural elements, wall elements, etc.) are numbered, each component can be assigned its exact mounting location within the shell.

If, in the course of the 3D measurement of the shell, it is shown that the ground is not sufficiently level, then a corresponding horizontal compensation can be achieved by using a suitable, preferably non-sagging, counterbalancing material, eg a bed or a screed, preferably a non-sagging composite screed, laid in a suitable manner or

is applied, in which case - after production of a flat bottom surface - if necessary, the interior of the 3D scanner is to be measured again.

For this purpose, however, it is advantageous, using the data of the CAD model, to calculate and produce a suitable geometry of a rail structure to be laid on the floor of the shell (for example, a plurality of rails with a triangular or quadrangular cross-sectional shape) Rails of the rail structure cover the entire floor of the interior grid-like and define with its upper edge or top a precisely horizontal plane. The varying over the respective rail length for the purpose of height compensation height of the rails as calculated from the CAD model thus compensates for the uneven or inclined floor, in which case the spaces between the rail structure flush with screed, preferably one (not or only slightly sagging)

Composite screed or a suitable floating screed (or other filling) to be filled. Equally, instead of the above-mentioned rail structure, spacers (of arbitrary cross-section) to be distributed over the entire floor of the shell can be used which are dimensioned in their geometry so that their upper sides define or span a flat surface, whereby at the location of each spacer Distance between the bottom of the shell and the horizontal plane is fixed. The spacers (in particular their upper and lower end faces) can also be produced precisely to achieve sufficient precision in step (D) of the method according to the invention using a computer-assisted processing step calculated using the CAD data and the intended mounting location of the respective spacer or edited. Expediently, a rail structure to be calculated in this way or the geometry and the exact location of the rail system to be installed for this purpose Spacers or the resulting level of a flat and horizontal floor surface are added to the data of the CAD model, so that no re-measurement of the interior of the shell is necessary and steps (A) to (D) can be performed before the - For example, in step (D) produced on the basis of the calculated geometry - height compensation of rail structure / spacers and screed at the beginning of the process step (E) is generated.

It has been found that it is possible in the below-described use of a full-surface base plate forming structural structure, first to lay the base plate on the rail structure and the spacers and only then the space between the rail structure or between the spacers with a

Flooring screed through at least one suitable opening in the base plate to fill. As a result, it is possible to achieve a screed lining which exactly fills the intermediate space and which is exactly horizontal on its upper side, optimally supporting the baseplate in the region between the rail structure or the spacers while avoiding unwanted voids.

An advantageous development of the invention provides that the construction structure is a base plate, which consists of a plurality of substantially flush to be laid (and the structural structure elements forming) base plate elements, wherein the base plate covers the bottom surface of the interior substantially over the entire surface. In this case, it makes sense to initially manufacture the individual base plate elements as standardized components with predetermined geometry (eg as rectangular plates) and to perform a (computer-assisted) adaptation of the geometry only for those base plate elements where this is due to the geometry of the shell or for the purpose of introduction a - for the positionally correct positioning of a wall element certain - positioning element is necessary. Such a base plate forms a particularly stable Starting point for the mounted on it further components of the internal structure. The individual base plate elements preferably have a circumferential edge

high precision manufactured - e.g. CNC-grooved - groove, with which each two adjacent base plate elements - using a separate spring strip - can be laid right-aligned to each other via a tongue and groove connection.

Furthermore, it is preferably provided that as a positioning element adapted in its width to the width of the bottom-side edge of the wall element groove in the

The upper side of the base plate is used, in which the wall element is adjusted in the context of the assembly according to step (E) with its bottom - side edge. This groove extends in length - depending on the specific course of the wall element having Innwand - usually a plurality of respectively adjacent base plate elements. The groove should be advantageously introduced by means of a CNC milling process in the top of the respective base plate elements and allows a positionally accurate and particularly stable connection of the relevant wall element to the base plate serving as a construction structure.

For this purpose, it is obviously preferred if the wall element is also made at least partially of a CNC-milled material (for example of wood), wherein at least the bottom edge of the wall element is machined by means of a CNC milling machine. For in this way it is possible in a simple manner to produce a particularly precisely fitting form fit between the groove introduced into the baseplate elements in computer-assisted fashion and the base-side edge of the wall element to be set here.

In addition, it is preferably provided in the context of the invention that at least one inner wall of the interior has two spaced-apart wall elements positioned with their bottom edge in accordance with each other at a distance and as positioning elements serving grooves in the base plate, wherein the steps (C), (D) and (E) - for exact calculation of the plate geometry and correspondingly accurate production and precise assembly - find correspondingly applicable to these grooves or the base plate elements containing these grooves.

Furthermore, in the context of the present invention, a particularly good noise reduction can be achieved if the base plate elements forming the base plate are laid in step (E) on a layer forming a footfall sound insulation layer, which in turn is essentially laid over the entire area of the floor surface of the shell. Of course, the geometry of this bottom side in the shell to be laid impact sound insulation panels calculated using the data of the CAD model and the plates are also made correspondingly accurate. Correspondingly suitable insulation boards are known from the prior art.

In a further preferred embodiment, it is provided that the interior construction also comprises a support structure interrupted by the at least one inner wall, the support structure having a horizontally extending support plate for a flooring to be laid thereon and a plurality of spacers to be placed thereunder, the spacers being secured by suitable positioning means (For example, a tongue and groove or other positive connection) in the exact position of the construction structure (eg the aforementioned base plate) and the support plate by means of suitable positioning means (eg a tongue and groove or other positive connection) are accurately positioned on the spacers can, wherein the aforementioned positioning means each comprise at least one positioning element (eg, a groove, a spring (strip), a bore and / or a pin), which on the spacers, the structure structure and / or the Tragpl is educated. It is further preferred that in step (C) based on the data The CAD model also calculates a suitable geometry of the support plate composed of a plurality of support plate elements and a suitable geometry of the spacers, wherein the geometry of the support plate elements, the structural elements and / or the spacers include the exact location and geometry of the aforementioned positioning elements. Furthermore, it is then necessary to ensure that in step (D) the support plate elements, the

Structural structural elements and the spacers of the support structure in the geometry specified in step (C) are prepared, said positioning elements by means of a computer-aided machining step (eg CNC milling) in the respective support plate elements, the relevant structural elements and / or the spacers are introduced and that in Frame assembly of the interior according to step (E) and the support structure is installed according to the right position to the structure structure.

The spacers may be, for example, slats, upright boards and / or cuboidal or cylindrical elements whose height defines the distance of the support plate from the bottom of the shell or the base plate. The number, geometry and position of the spacers to be used is - depending on the geometry of the other interior - chosen or calculated so that the support plate is supported at each point sufficiently on the ground or the base plate.

Such a supporting structure for a flooring to be laid on its supporting plate proves to be advantageous in many respects.

For one thing, the resulting in plan view between the spacers cavities (between the support plate and underlying base plate or floor or other structural design) with a suitable insulating material, eg glass wool, foam, etc., are filled, whereby a further improved heat and noise insulation can be achieved.

On the other hand, the support plate can also serve to accommodate an underfloor heating, for which it is advantageous if the spatial planning in step (B) also includes a plan for a to be integrated in the top of the support plate of the support structure underfloor heating, and

that in step (D) by means of a CNC milling machine using the data of the CAD model in the relevant support plate elements, a suitable recess for the underfloor heating to be integrated therein is milled. Thus, a floor heating can be planned very flexible and easy and precise installation by the floor heating in step (E) is easy to install in the recesses mentioned.

A further advantageous embodiment of the present invention provides that the spatial planning in step (B) has at least one door or another opening (eg a doorless passage, a hatch or an opening behind a window) through the at least one inner wall that in step (C) on the basis of the data of the CAD model also the geometry of an opening required for the opening through the at least one wall element is calculated, and that in step (D) the

Breakthrough is created by the relevant wall element using the data of the CAD model by means of a CNC milling machine. Thus, the breakthroughs for doors, windows, etc. can be planned and implemented with high precision, whereby e.g. Also, any door frames, doors and / or hinges can also be planned and manufactured accurately before the final assembly of the interior.

With the method according to the invention, furthermore, if a layer of liquid screed is (again) to be used to construct a suitable floor covering above the construction structure, a high degree of precision can also be provided for this by the interior fitting having a plurality of its top edge exactly horizontally extending Abziehleisten for a liquid screed, which are connected by suitable mounting elements directly or indirectly with the construction or support structure, whereby also preferred to suitable positioning means to ensure an exact relative position between the respective Abziehleiste and the construction or Support structure is used.

These positioning means in turn advantageously comprise at least one positioning element which is formed in step (D) of the method according to the invention in the mounting elements for the Abziehleisten and / or the construction or support structure, preferably by means of a computer-aided processing step of the respective components of the interior, such as this has already been explained above.

As part of the assembly of the interior according to step (E) can then be filled after mounting the Abziehleisten the space between them with a liquid screed or similar, applied liquid and later hardening leveling compound and -. with the aid of a run on the upper edge of at least two adjacent Abziehleisten guided or installed on this before filling the gap plate - to ensure a precisely flat and complete filling of the space between the Abziehleisten. By the way, the actual requirement for leveling screed can be calculated much more accurately than was the case in the known state of the art. After desiccation of the screed may then be on this, if necessary. Another floor covering be laid.

Again, as mentioned above in a similar context, instead of a plurality of Abziehschienen be resorted to a plurality of spacers, which also with their top one define exactly horizontal ground level and by means of suitable positioning means (see above) should be positioned exactly and positionally right to the construction or support structure.

In a further aspect of the present invention, the interior construction can also comprise a formwork for an internal staircase that can be mounted in a positionally correct manner relative to the construction structure by means of corresponding positioning means, which can thus also be produced precisely and without measurement on site. Again, the same aspects apply to suitable positioning means, as already explained above.

The method according to the invention can be further developed in a particularly expedient manner in that the spatial planning in step (B) provides at least one break-through required by a wall element and / or the support plate of the support structure for the purpose of heating, sanitary and / or electrical installation. and

in step (D), the relevant breakthrough is introduced by the wall element and / or the support plate using the data of the CAD model by means of a computer-aided processing step in the relevant wall element or the respective support plate element. Thus, on site, the assembly costs for heating / plumbing / electrical installations can be significantly reduced, since then the relevant components only used in existing and precisely positioned recesses of the relevant components and, if necessary, must be secured therein. In this way, for example, in a particularly advantageous manner can be exactly flush mounted in an inner wall integrated light switch, sockets, flatscreens, etc. Similarly, by corresponding recesses or openings in wall or ceiling elements and precisely positioned lighting fixtures (eg lamps, spots, indirect lighting elements, etc.), possibly sunk, install, creating an ideal lighting concept for the interior design can be realized. Because of the achievable with the present invention precision of the interior design, the entire lighting concept - based on the available CAD data - precalculated and visualized on the computer, which also facilitates the planning of a suitable lighting concept.

It thus makes sense that the CAD or CAD model relevant to spatial planning or interior design, which preferably contains all the data entered and the geometries of all the components to be used as calculated in the context of the method according to the invention, also comes to the companies responsible for the electrical, heating and plumbing installations so that they can incorporate all the breakthroughs required for the particular installation into the model through the relevant interior finishing elements, which can already be taken into account during the manufacture of the components in question - by means of precise computer-aided machining methods.

Furthermore, it is preferably provided that the at least one wall element on its facing an interior surface is at least partially veneered with a the inner wall surface forming drywall and / or a floor strip, which in particular a precisely aligned arrangement and prefabrication of inner wall surface and skirting or other mounting elements such Light switches, sockets, flat screens, etc. is enabled. Obviously, it is also expedient if the geometry of the drywall (s) and / or the skirting board (s) in

Step (C) (including the required breakthroughs or recesses) are calculated using the data of the CAD model or the geometries of the flush-mounted installation elements are inserted accordingly, then in step (D) using the data of the CAD model the drywall (s) or skirting board (s) processed accordingly by means of a computer-aided processing step and finally in step (E) accordingly be mounted in the correct position. The achievable precision allows the realization of a particularly pleasing in terms of interior design with precise

running (shadow) joints - at the same time easy installation.

For positionally correct mounting of the drywall and / or the skirting board, at least one positioning element (for example a groove or a bore) can be provided, with the aid of which a correct installation of the drywall or skirting board on the wall element is permitted. For this purpose, if necessary. Also be provided a mounting strip on which the drywall and / or the skirting board is mounted, this being for the purpose of their positional rights

Positioning e.g. with a groove formed on the wall element (or other suitable positioning element) can cooperate.

In a further preferred development of the present invention it can be provided that in step (A) of the method according to the invention before the implementation of the measurement of the interior of the shell at least two of the bottom surface of the interior of the shell protruding reference objects permanently installed (eg screwed into the ground ), whose geometry and position are then measured precisely together with the interior of the shell. These reference objects can then later be used for the positionally correct positioning of a structural component (for example a planar base member) to be mounted in this region and, if necessary, also for the positional positioning of further interior structural elements (for example a support structure).

For this purpose, in step (C), on the basis of the data of the CAD model, a suitable cutout for a structural element to be mounted in the region of the respective reference object can be calculated, wherein the cutout in its position and geometry of the position and geometry of the reference is adjusted so that the structural element structure (or the support structure element) with the aid of the recess fit - eg form-fitting - can be placed on the reference object. A non-symmetrical cross-section of the reference object and the recess (eg an oval pin cross-section and a corresponding oval recess) can thereby facilitate the positionally correct positioning of the relevant structural element again.

Thus, if the reference object is e.g. is formed in the manner of a protruding from the bottom of the shell bolt or pipe section, it is appropriate if the corresponding in a structural element (eg a base plate member) corresponding recess by means of a computer-aided processing step is precisely manufactured, so that the base plate member in the context of Installation of the interior can be placed in the correct position on the projecting from the bottom of the shell bolts.

Furthermore, it is advantageous if the length of the at least two reference objects is dimensioned such that they each extend at least up to the (height) level of the surface which forms the basis for the floor covering of the interior construction. The reference objects whose position within the interior of the CAD model is known exactly, thus - as long as they are visible or as long as they were not removed again, which could also be provided - as "template" or reference points for any further assembly steps within serve the interior.

Finally, the present invention is also directed to an interior construction of a shell manufactured according to the method explained above, which thus comprises at least one inner wall having at least one wall element and at least one construction structure serving as positioning aid for the wall element, wherein at least one for positionally positioning the at least one wall element on the construction structure serving positioning means is provided, which has a produced by means of a computer-aided machining method positioning element on the wall element and / or on at least one structural element.

For the interior construction constructed or produced in this way, the same aspects apply, as have already been mentioned above in connection with the method according to the invention, so that reference can be made to avoid repetition.

 Of course, all aspects directed to preferred developments of the method according to the invention also apply in the same way to corresponding refinements of the interior fitting according to the invention.

The invention will be explained with reference to the embodiments shown in more detail in the drawing. It shows

 Fig. 5 shows another bottom cross-section through a second embodiment of the present invention.

In Fig. 1, a (not to scale) floor plan of a shell 1 is shown, in which an embodiment of an interior 2 according to the invention is to be installed or installed in accordance with the invention. The better overview 1 shows the interior 2 without the support structure shown in Fig. 2

The shell 1 could in principle be constructed much more complex, but for the purpose of a better illustration of the present invention, for the sake of simplicity, only a peripheral wall 3, in the lower part of FIG. 1 approximately centrally a breakthrough 4 (eg for an entrance door) having. In the wall 3, however, further openings, e.g. for windows or the like, be provided. In addition, the bodyshell could, for example, also comprise further elements (eg load-bearing (interior walls, pillars, etc.)) In the vertical direction, ie perpendicular to the plane of the drawing in FIG. 1, the shell 1 to be removed is raised upwards by a cover (see FIG. 3) and bounded below a bottom (see Fig. 2) .The wall 3 delimiting the shell 1 on all sides differs significantly in the cross-sectional view shown in Figure 1 from an ideal rectangular shape, as originally planned for the shell, This deviation is shown here for the sake of clarity greater than is to be expected in practice.

At about the middle of Fig. 1, there is shown schematically a 3D scanner 5 emitting a laser beam L, with which in a first step (A), i. before the interior construction 2 is planned and mounted inside the shell 1, the interior 6 of the shell 1, i. the inner shell 7 of the wall 3 limiting the shell 1 inside are measured with high precision.

From these measurement data relating to a number of terms of their position relative to the 3D scanner 5 measured measurement points, a 3 -dimensional CAD model of the (initially empty) the inner space 6 of the shell 1 is created in the usual ^'manner, which is therefore all the relevant data for History of the bottom of the shell, the ceiling of the shell and the inner sides 7 of the wall 3 of the shell 1 contains. Thereupon can in a step (B) a suitable spatial planning 8 for the interior design 2 are created. This - in Fig. 1 recognizable in the plan - - 8 includes here two interior space 6 of the shell 1 at an angle traversing inner walls 9, 10 and in the interior 6 of the shell 1 rectilinear inner wall 11. Furthermore, the interior includes 2 (or the spatial planning , which represents the model of the interior 2 to be entered into the CAD model), a further inner wall 12, which circulates as an outer boundary the interior of the interior, this more or less close to the inside 7 of the wall 3 of the shell and extends only in de Breakthrough 4 of the wall 3 of the shell is interrupted. The course of the inner wall 12 has been selected such that it defines in its interior an exactly rectangular interior space that is as large as possible within the space predetermined by the shell 1, which is then subdivided further by the further inner walls 9, 10, 11.

As a positioning aid for the correct position mounting of the inner walls 9 - 12 within the shell 1 is also a bottom side laid and essentially on the

Base surface of the shell 1 extending, but this distance from the wall 3 of the shell 1 spaced, construction structure 13 is provided, which is composed of a plurality or plurality of structural elements 14, 14 ', 14 ·'. In the present case, these are a plurality of flat base plate elements 16, 16 ', 16'', which are laid flush to form a base plate 15 in the shell 1, wherein the base plate 15 covers the entire floor of the interior to be built 2 over the entire surface and - the cross-sectional view of FIG. 1 - to all sides on the outer inner wall 12 of the interior 2 (slightly) out. In the context of the preparation of these base plate elements 16, 16 ', 16''is used in this case to precisely manufactured, rectangular base plate elements of a given standard geometry, for the purpose of fitting the base plate 15 in the interior 6 of the shell 1 in particular those in the edge region of the shell 1 to laying base plate elements 16 must have a different geometry from the standard geometry. The two - lying on opposite inner sides 7 of the wall 3 of the shell reference points Rl and R2 are the correct position mounting all base plate elements 16, 16 ', 16''by the connecting line of the reference points Rl and R2 exactly with the line B of two adjacent rows A , C coincides with base plate elements 16 and by - from the CAD model - the to be observed during assembly distance of a predetermined point on a base plate (eg a vertex) to the reference point Rl and / or R2 is known.

The exact geometry of the individual base plate elements 16 is calculated on the basis of the data of the spatial planning 8 of the interior design 2 containing CAD model.

According to spatial planning 8, the interior walls 9, 10, 11 effecting the division of space should each have a door 17, 18, 19, for which purpose the respective inner wall 9, 10, 11 on both sides delimiting wall elements 20, 21 and the drywall panels 22 attached thereto as a panel, 23 (see Fig. 2 for the inner wall 10) corresponding openings 17 ', 18', 19 'must be introduced. The outer inner wall 12 is - viewed over its length - partially advantageous from only one vertical plane defining

Wall element.

FIG. 2 shows a sectional view of the interior construction 2 according to section line II-II from FIG. 1 in the floor area of the interior construction 2. The somewhat inclined course of the floor 24 of the shell 1 has already been detected by means of the 3D scanner 5 during the measurement of the shell 1 , On the basis of these measurement data, the geometry of a plurality of triangular profile rails 25, 26, 27 was calculated, which define a precisely horizontally extending plane with correspondingly correct laying within the shell 1 with their pointed upper edges. The gap between the rails 25, 26, 27 was then flush with a composite screed 28 filled, whereby a horizontal bottom surface 29 has been achieved. A footfall sound insulation 30 is laid on this surface over the entire surface, which in turn forms the basis for the construction structure 13 forming the base plate 15, of which in FIG. 2 a section through two base plate elements 16 'serving as construction structure elements 14', 14 "and laid side by side. , 16 '' is shown. The

Base plate elements 16 ', 16' 'are connected to each other by means of a tongue and groove joint 32. For this purpose, the base plate elements 16 ', 16 ", which are prefabricated as standard components with precise geometry with an error tolerance of less than 0.1 mm in the outer geometry, have a circumferential groove 33 surrounding the base plate element 16', 16" - at approximately half the height of the plate so that each two adjacent base plate elements 16 ', 16' 'using a separate spring strip 34 by means of a tongue and groove joint 32 can be positioned positively and precisely to each other.

It should also be noted that the base plate element 16 'shown on the left - here approximately in the middle of the wall 10 - is again divided into two separate partial plates 16a', 16b ', between which a suitably dimensioned cork or rubber strip 31 is clamped. This assists the sound insulation between the two spaces of the interior structure 2 separated by the wall 10, since the sound can thus not be transmitted from one space to the other via the base plate element 16 '. A corresponding sound insulation (by subdividing a base plate 16 into two sub-panels with an insulating body therebetween, which is formed here by the cork or rubber strips 31) is advantageous for each base plate element 16, which under an inner wall 9, 10, 11 of the interior passes through. The inner wall 10 includes - as well as the other inner walls 9 and 11 of FIG. 1 - two spaced apart and parallel wall elements 20, 21, the space is filled with a sound-insulating material 40 and if necessary. To the laying of - not shown - cables or Pipes can be used for the electrical, heating and plumbing installation. Both wall elements 20, 21 are on their side facing the adjacent interior side with a - the actual wall surface forming - Drywall 22, 23 and a matingly aligned flush bottom bar 41, 42 blinded. As an assembly aid for the correct position mounting the drywall 22, 23 and the

Floor strips 41, 42 each serve a horizontally extending mounting profile 44, which is mounted on a serving as a positioning element and CNC-milled groove 43 in the respective wall element 20, 21 correctly positioned.

On the upper side 35 of the base plate element 16 ', two spaced-apart grooves 36, 37 are introduced by means of a computer-assisted processing step, in this case a CNC milling operation, into which a wall element 20, 21 with its respective lower edge 38, in the context of assembly of the interior. 39 was set from above according to the arrows D and E. The width of the grooves 36, 37 is exactly adapted to the respective width of the lower edge 38, 39 of the wall element 20, 21 set therein, so that in each case serving as a positioning means 45 and 46 positive connection between wall element 20, 21 and base plate element sixteenth 'arises.

Above the base plate elements 16 'and 16 ^{1 1} is - interrupted by the inner wall 10 - a support structure 47 installed, which comprises a plurality of spacers 48 and a support plate 49 consisting of different support plate elements 49a, 49b, wherein the spaces between the support plate 49 and the base plate 15 are filled with insulating material 40. The base plate elements 16 ', 16''are connected by means of a first tongue and groove joint 50 with the spacers 48 and the spacers 48 by means of a second tongue and groove joint 51 with the support plate 49. The support plate 49 serves as the basis for a ver ^¬ laid flooring 52, 53 and has on the top side a plurality of CNC-machined recesses 54, in which the lines 55 of a floor heating are laid.

Furthermore, the wall element 20 shown on the left in FIG. 2 and the drywall 22 attached thereto have a breakthrough 56 introduced into the relevant components by means of a CNC milling machine, in which - according to appropriate planning in the CNC model of the interior design - a socket 57 of known geometry exactly recorded.

The support plate 49 and the respective floor covering 52, 53 are finally supported by means of suitable insulating body 58 for soundproofing purposes against the respective adjacent wall element 20, 21 of the inner wall 10.

Fig. 3 shows a sectional view of the interior 2 according to section line II-II of Fig. 1 in the ceiling region of the interior 2, so that a possible type of connection of the inner wall 10 to the ceiling 59 of the shell 1 is apparent. The inner wall 10 comprises the wall elements 20, 21, which extend parallel to the ceiling 59 from the floor 24 to just below the ceiling 59, and which are each faced with a drywall 22, 23 for the respectively adjoining interior. The wall elements 20, 21 are in their the cover 59 of the shell 1 facing end portion 62, 63 held with some play in the vertical direction in each case in a downwardly open U-shaped profile element 60, 61. The two profile elements 60, 61 are respectively screwed by means of screws 64, 65 with a spacer element 66, whereby the distance between the two wall elements 20, 21 also on the ceiling side - in correspondence of the bottom side by the grooves 36, 37 predetermined distance (see FIG .. 2) - is fixed. In this case, 66 flexible or elastic compensating elements 70 are provided between the U-shaped profile elements 60, 61 and the spacer. The - for example made of wood - spacer 66 is in turn connected in the section of Fig. 3 by means of a, at a precisely prespecified point in the ceiling 59 to be driven screw 67 to the ceiling 59, wherein between spacer 66 and ceiling 59 two more on both sides of the

Screw 67 extending intermediate elements 68, 69 are provided. For exact positioning of the screw 67, a suitable hole in the ceiling is pre-drilled. The exact location of the hole required for this purpose, which can be determined from the CAD model for interior work 2, can be determined by the following method. At a point exactly vertically below the required hole of the there too

laying base plate element 16 'is - e.g. computer aided - a marker attached. At this point, after correctly positioned mounting of the relevant base plate element 16 ', a laser pointing exactly in the vertical direction is set up, whose laser beam (see arrow F) thus defines the exact position for the hole in the ceiling 59 of the shell 1.

Furthermore, the interior construction 2 comprises on the ceiling side still between the partition walls 9, 10, 11, 12 suspended inner ceiling 71, in which two adjacent inner ceiling panels 71a, 71b are bolted to a connecting element 72, which in turn to a bolted to the ceiling 59 mounting bar 73 (FIGS. or a mounting plate 73) is screwed. For positional positioning of the bolts holding the mounting plates or screws holding the same method can be used, as explained above in connection with the positioning of the screw 67.

Finally, FIG. 4 also shows a flow chart showing the steps (A) to (E) of the method according to the invention and its preferred further developments, which were used in the construction of the interior construction shown in FIGS. 1 to 3. The cross-section shown in Fig. 5 shows a further embodiment of an interior construction according to the invention, in which - before the 3 -dimensional measurement of the interior of the shell - a serving as a reference object bolt 74 was screwed into the bottom 24 of the shell, so that he from the Floor 24 protrudes and can serve as a positioning aid for other interior finishing elements.

The part of an interior shown in Fig. 5 has - as that of the embodiment of FIG. 2 - first a bottom-side layer screed 28, in which case no rail structure 25, 26, 27, but a plurality of individual spacers 75, 76, 77, 78 is used whose space was filled with screed 28. On the screed 28 a footfall sound insulation 30 was then laid, on which finally - correctly positioned - a construction structure 13 forming base plate 15 has been laid. Alternatively, however, could also, for example, a

Base plate with integrated footfall sound insulation can be used. In the area of the bolt 74 serving as the reference object, both the impact sound insulation and the base plate 15 have a corresponding recess, which serves as a positioning aid for the construction structure as a whole. Preferably, in the context of laying the individual base plate elements (not individually recognizable in FIG. 5), the base plate element which has the recess for the reference object 74 is laid first, whereby its positionally correct positioning and alignment can be ensured in a simple manner.

On the base plate 15 there is a thermal insulation 40 followed by another impact sound insulation 79, over which finally a likewise pierced by the reference object 74 in the region of a recess support plate 49. The support plate 49 is part of a supporting structure (not completely shown in FIG. 5) which, by means of suitable spacers and suitable positioning means, can fair and accurate position on the base plate 15 has been attached.

On the support plate 49, a plurality of extending perpendicular to the plane Abziehschienen 81 is fixed, which are respectively by means of mounting elements acting as foot parts 80 right to support structure, namely on the support plate 49, and their upper edge are all in an exactly horizontal plane. The space between the Abziehschienen 81 was filled with a flow screed 82, on which finally a floor covering 52, 53 was laid. The inner wall 10 shown in FIG. 5, which interrupts the support structure, is constructed similarly to the inner wall 10 already shown in FIG. 2.

Before laying the floor covering 52, 53, the upper end face 83 of serving as a reference object pin 74 is always visible and thus defines a bottom-side reference point 83, which can be used for correct position mounting other elements in the interior. In interaction with at least one further, equally generated reference point (not shown), each object to be installed in the interior of the interior construction can be positioned exactly by specifying its relative position to both reference points.
