Abstract

The invention relates to a log-cabin type façade for cladding walls in internal and external areas. Said façade comprises elongated contoured elements (12) and corner elements (16), which are designed to produce an interior corner and an exterior corner for internal and external areas.

Description

The invention relates to a block-like facade according to the preamble of claim 1.

From the U.S. Patent 5,638,649 a blockhouse-like facade for covering exterior walls is known, which consists of a plurality of elongate profile elements for covering the wall surface, which can be arranged one above the other and includes Eckausbildungselemente associated with the side profiles and can be arranged as crosswise superimposed strains to form an outer corner. The profile elements and the Eckausbildungselemente form the impression of a massive Blockhausweise.

For the design of this blockhouse-like facade is required that when using the same profile elements for the lining of the wall sections for the preparation of an outer corner differently shaped Eckausbildungselemente are provided to build the blockhouse-like facade. Thus, left and right corner forming elements are required to create a composite that is not intended to show interfaces to the viewer and is very close to a true log cabin facade as a faux. Due to the design of the different Eckausbildungen the creation of such a facade is expensive. In addition, the profile elements have the disadvantage that they do not rest flush with each other over prolonged use, but can widen at the joints.

From the US 6 199 332 B1 is also a facade cladding for the formation of a block-like exterior facade known to be provided in the same design profile elements on the wall surfaces and different Eckausbildungselemente are provided as a pre-milled wooden stump for a right and a left connection. Also in this embodiment, the same disadvantages as in the previously described blockhouse-like facade. The same applies to the US 5 586 422 A ,

The invention has for its object to provide a block-like facade for walls in the interior and exterior, which allows the simple design of the elements rapid production and erection of the facade and allows independent of the arrangement and orientation assembly of the elements to a facade.

This object is achieved by the features of claim 1.

The inventive design of the facade has the advantage that the elongate profile elements are identical, so that they can be used both on an inner wall and on an outer wall and both at its right and at its left end have the same connections. These elongated profile elements can be used both for the production of an inner corner and an outer corner in the interior or exterior. Furthermore, the facade according to the invention has the advantage that the Eckausbildungselemente are also formed identically and regardless of their arrangement at a left or right end of a to be imitated strain to form a cross dressing find their use.

This provides a simple and cost-effective production for a facade. In addition, a simple kit of two elements is provided, which allow the complete erection of a facade. Such profile elements and Eckausbildungselemente can be provided as a kit that allows both the skilled person and for the handyman a simple and quick installation. In addition, these simple geometric shapes for the elongated profile element and the Eckausbildungselement on a high design freedom.

The arrangement of a transverse recess near the end faces of the profile elements for the cross dressing of an opposite profile is at the same time allows that with a profile element an outer corner and an inner corner of a facade can be produced.

According to an advantageous embodiment of the invention it is provided that the profile elements and the Eckausbildungselemente with plug connection elements, preferably bolts, in particular made of wood or wood dowels, are interconnected. This can be a simple assembly with a high stability, which is made possible by simply mating or assembling.

According to an advantageous embodiment of the invention, it is provided that at least two plug connection elements are provided at each connection point between the profile elements and Eckausbildungselementen. This can be given a stable arrangement and attachment. Gleichzeltig is given by the presence of at least two connecting elements a rotation.

Advantageously, it is provided that at least two holes for receiving the plug-in elements are provided at each connection point of the profile element. Thus, the individual elements are prefabricated for the production of the facade, so that a simple assembly is possible without further processing.

According to a further advantageous embodiment of the invention, it is provided that the corner connecting elements each have at least two bores for receiving the plug connection elements on a left and a right portion of a connection surface. This makes it possible that the corner connecting element as such is universally possible for the arrangement of a left or right side or for producing a degree in the X or Y direction of the cross association. The connector elements are provided either on the at least two left or right holes of the pad.

The profile elements are formed according to a preferred embodiment in cross-section as a semi-circular profile, which includes a round, a tree trunk mimicking outside and an inside as a contact surface with depressions. The depressions provided on the inside can be provided, for example, in the shape of a W or V, triangular or the like. These have the advantage that when using natural wood as a profile element splitting during drying of the process is prevented. At the same time supply lines can be introduced in these wells, for example, to provide a wall lamp or the like, which is attached to the facade, with energy. Of course, any other applications are possible.

According to a further advantageous embodiment, the profiled element has a spring in its longitudinal extent on an upper section and a complementary groove on the opposite underside. This makes it possible that a secure meshing of superimposed profile elements for covering a wall surface is made possible. Tongue and groove training also enables that a popping or bulging einzeiner sections of a profile element is prevented after prolonged use. As a result, a dense arrangement can be created.

Advantageously, a web surface is formed on an underside of the profile element between an outer side and the groove, which is designed to be placed on a further profile element. On the one hand, this web surface makes it possible for the design of the spring of the profile element arranged underneath to be completely concealed. At the same time, the character of a massive log house construction is increased.

In FIG. 1 is a blockhouse-like facade 11 is shown in perspective. This partially explosive representation shows the interaction of elongated profile elements 12 and disposed thereon intermediate pieces 14, which are assembled with Eckausbildungselementen 16 to form an outer corner. The facade 11 may be provided for both the interior and for the outdoor area to disguise a non-illustrated wall. The composition of the profile elements 12, spacers 14 and corner formations 16 will be explained in more detail after the description of the individual elements.

In FIG. 2a the profile element 12 for the facade 11 is shown in perspective. The elongated profile element 12 is formed as a half-round profile, as the sectional view according to FIG. 2b shows closer. The profile element 12 is mirror-symmetrical to the central axis 19 and has at each end face a first planar connection surface 21, which merges into a second connection surface 22 formed by a quarter-circle-shaped cutout. At an upper portion 23 of the profile element 12, a spring 24 is formed over the entire length in the longitudinal extent of the profile element 12 seen. This spring 24 is spaced to a rear abutment surface 26. At a bottom of the profile element 12, a groove 28 is complementary to the spring 24 is formed. This groove 28 is like the spring 24 offset by the same distance from a contact surface 26, so that a safe engagement of the spring 24 in the groove 28 is made possible when superimposing the profile elements 12.

The profile element 12 has 26 recesses 29 outgoing from the contact surface. According to FIG. 2b For example, three recesses are provided, wherein their number and size is arbitrary. The contact surface 26 opposite an outer side 31 is formed, which is formed almost semi-circular and ends at a lower portion at a lower edge 32. From this edge 32, a web surface 33 extends upwards to the groove 28. This web surface advantageously has a concave surface whose radius of curvature corresponds to that of the outside 31. This web surface 23 is flush with an underlying profiled element 12 in the assembled state and covers the groove 22 and fasteners not shown in detail, such as. Nails, soft in a transition region 36 can be introduced into holes 37 ( Figure 2c ). These holes 37 run diagonally down to the contact surface 26, so that the profile element 12 can be fastened to the wall and the attachment is not visible.

The profile element 12 can thus be secured in the transition region 36 to the wall. An overlying profile element 12 engages with the groove 28, the spring 24, wherein a holding portion 38 behind the spring 24th engages, so that in this area a firm investment of the lower portion of the overlying profile element 12 is given to the underlying profile element 12. At the upper portion of the profile element 12 near the spring 24 again fixation via fasteners on the wall. Thus, a secure attachment of the profile elements 12 may be given, which also meets the requirements of the wind loads.

In the first pad 21 two holes 41 are introduced. These holes 41 serve to receive plug connection elements 43 (FIG. FIG. 1 ). The connector elements 43 are formed in the use of natural wood for the block-like facade 11 as a so-called wooden dowel, which can be plugged, possibly pressed and / or additionally also glued.

In FIG. 3 the corner formation element 16 is shown in more detail. The Eckausbildungselement 16 is made of a round body, preferably a roundwood stump, and has the back of a planar cutting surface 46 which is formed as an end face of a trunk. Opposite, a first connection surface 47 is formed. This connection surface 47 is flat and comprises a semicircular area. This is followed by a second connection surface 48, which is formed in the side view of the Eckausbildungselementes 16 by a quarter-circle-shaped cutout. This abutment surface 48 serves for abutment with the imitated trunk disposed below it, offset by 90 °.

On a lower side of the Eckausbildungselementes a concave surface 49 is provided, which has a radius of curvature corresponding to the radius of the stub of the Eckausbildung.

On the first stop surface 47, a right and a left pair of holes 51 is provided. This makes it possible that the Eckausbildungselement 16 can be used both as a left and right end element.

In FIG. 4 is a perspective view of the intermediate piece 14 is shown. The intermediate piece 14 has a connection surface 56, which is preferably formed congruently with the first connection surface 21 of the profile element 12. At the lower end of the intermediate piece 14, a concave surface 57 is provided, which has a radius of curvature which corresponds to the radius of the Eckausbildungselementes 16. This surface 57 is in positioning the intermediate piece 14 to the profile to an end face of the profile element 12 directly into the second connection surface 22 via.

The intermediate piece 14 advantageously has through bores 58, so that the plug connection elements 43 completely penetrate the intermediate piece 14 and are provided on the right and left side for receiving the profile element 12 and the corner forming element 16.

The facade 11 according to FIG. 1 is built on a pedestal 61. In a spatial direction, a profile element 12, an attached intermediate piece 14 and a Eckausbildungselement 16 is arranged. Following this, in a second spatial direction, a profile element 12 ', intermediate element 14' and a corner forming element not shown in more detail are assembled and placed on a base 61 in the further spatial direction. The Eckausbildungselement for the second spatial direction completely covers the intermediate piece 14, so that this intermediate piece 14 is not visible in the finished facade. The structure of the blockhouse-like façade in the cross structure follows alternately in the spatial directions, so that there is an interlocking of the individual elements and a mutual fixation.

It is also possible that first the profile elements 12 and 12 'are arranged and subsequently the intermediate pieces 14, 14' individually or in connection with the Eckausbildungselementen 16, 16 'are fastened via the connector elements 43.

In FIG. 5 a further alternative embodiment of the block-like facade 11 according to the invention is shown. This facade 11 is different away from the in FIG. 1 shown facade in that for the production of this facade profile elements 12 and corner connecting elements 16 are used, which are positioned on each other via plug connection elements 43. For this purpose, the profile element 12, which in FIG. 6 is shown in perspective, opposite to in FIG. 2 modified profiled element 12 and has in the second connection surface 22 near the first connection surface 21 on a transverse recess 66. This depression corresponds to the groove 24 and a shoulder 67, which is formed in the upper region of the profile element 12. This transverse recess 66 allows the simple arrangement of the profile elements 12 to each other to form an inner corner 69. The groove 24 of the profile element 12 engages in the recess 66 of the overlying profile element and forms a fixation.

Corner forming element 16 according to FIG FIG. 7 for the facade 11 according to the invention FIG. 5 differs from the Eckausbildungselement 16 according to FIG. 3 in that in the second connection surface 48 a recess 68 is provided which corresponds to that of the profile element 12 according to FIG FIG. 6 equivalent. This makes it possible for the first connection surface 47 of the corner formation element 16 to lie flush against the first planar connection surface 21 of the profile element 12, and a milling of the groove 24 in the crossing region of the profile elements 12 or at the outer end region of the profile elements 12 is not required.

• Bevor das Profilelement 12 verbaut werden kann, wird das Eckausbildungselement 16 an das Profilelement 12 angebracht und als Ganzes auf das darunter liegende Profilelement 12 aufgesetzt. Dann greift die Ausfräsung 66 in die Feder 24 des quer darunter liegenden, zu 90° versetzten Profilelementes 12 ein, vorzugsweise zur Hälfte über die Länge des Eckausbildungselements 16. Dadurch ist eine Versteifung der Ecke gegeben.

The structure of the facade 11 according to FIG. 5 takes place as follows:

• Before the profile element 12 can be installed, the Eckausbildungselement 16 is attached to the profile element 12 and placed as a whole on the underlying profile element 12. Then the cutout 66 engages in the spring 24 of the transversely underlying, offset by 90 ° profile element 12, preferably half over the length of Eckausbildungselements 16. This is a stiffening of the corner given.

Alternatively, it can also be provided that the Eckausführungen - seen in plan view - deviate from a 90 ° angle, the Querausfräsungen 66 are accordingly adapted to the given angle.

The inventive facade 11 according to the FIGS. 1 and 5 has the advantage that a kit is formed with elements that can be used for both a left and a right orientation or side. The structure is considerably easier. One of the massive log cabin facade optically appropriate facade is made possible.
