Description

The invention relates to a Wall element for wooden structures and a method for producing such a wall element.

The half-timbered construction has been around for several centuries used to create residential houses, whereby a framework with vertical bars, cross bars (Lower chord, upper chord) and possibly diagonal bars is formed with suitable wall or partition elements to be fanned out. During the framework are designed according to static criteria the partition elements usually on optimal thermal insulation designed. In the old half-timbered buildings, these were Compartmental elements made of clay / brick elements or other mineral elements Building materials formed.

Nowadays you can still find the half-timbered construction Wooden buildings, the truss frame made of solid wooden beams is manufactured, while the partition elements usually from two plate-like spaced apart Cover layers exist and the gap between these cover layers by insulation a filling or is filled out by foaming.

To create the truss for the truss frame beams made of core-separated small wood are used, so that a certain minimum thickness of the tree trunk is required to make a bar with the predetermined Manufacture dimensions and with the predetermined strength to be able to. For this purpose, the outer layers of the tree are sawn off until the cuboid Basic shape of the beam with smooth outer surfaces results. This manufacturing method hides the Disadvantage in that considerable amounts of lumber incurred, which is usually reduced at most and chipboard or other inferior products is processed.

The half-timbered construction in the conventional form requires furthermore careful drying of the core-separated Weak woods, because of poorly dried Truss girders there is a risk that this Warping temperature and humidity fluctuations, so that the truss walls get cracks.

A disadvantage of the conventional timber truss construction Compartment elements used is that only a lack of strength can be achieved. At Insulation fillings and insulation foams can it can happen that not all of the space is filled will, so that only an insufficient or uneven Isolation effect can be achieved. Especially with Fillings of filled compartments can be added later post-processing with extreme difficulty, because when cutting the partition element the Filling can at least partially escape. Another The disadvantage of the known partition elements is that that small animals, such as martens or small rodents, in the space between the two cover layers can penetrate.

EP 0 388 507 A2 discloses a wooden beam and a process for its manufacture, in which a Cut logs in the longitudinal direction and the Individual elements put together to form a wooden beam be that the bark edges are facing each other.

DE-C-826347, GB-A-2052596 and FR-A-2583802 concern truss constructions in which the Truss bars made of several layers of wood are composed.

In contrast, the invention is based on the object a wall element and a method for its production to create those with minimal material adequate strength and heat / sound insulation is achievable.

This task is accomplished with regard to the wall element the features of claim 1 solved. Claim 7 relates to a method for producing a wall element according to claim 1. The wall element according to the invention, the developed by Ms. D. Graf, "Fachwerk 2000" to be named.

The invention Wall element has a multilayer structure, each layer of a plank, one on top of it trained insulation layer and a spacer slat layer consists. Then on this distance slat layer again the next layer of a board layer, an insulation layer and another spacer batten layer. It is particularly preferred if the spacer slat layer rests on the insulation layer so that the latter are applied over the entire surface of the plank can.

The two top layers of the wall elements will be in a preferred embodiment each by Board layer formed, being ensured by the spacer slats is that the predetermined distance of the Board positions is guaranteed. Because the insulation layer applied over the entire surface and held by the spacer slats is also a shift in isolation and thus an uneven insulation effect is excluded.

The spacers have the further advantage that Do not put small animals in the spaces between the cover layers can penetrate.

To create the board layers you can Class II and III weak woods are used, so that the material cost to manufacture the wall element much lower than with conventional wall elements should lie with either high quality Woods were used as top layers or else cheap molding materials that are neither in terms of strength still with regard to the insulation effect with the board position according to the invention are comparable.

Depending on the application, you can use one or both Cover layers (outer plank layers) further finishing layers be formed as visible surfaces. In this Final layer can then have recesses for receiving Sanitary / air conditioning / electrical equipment are trained.

The connection of the individual layers and layers of one Wall element is advantageously carried out by suitable Lanyards such as nails or Parentheses.

The independent claim 7 relates in particular simple process for making the aforementioned wall element according to the invention.

This method is preferred for old buildings used a mounting frame, on which a first Board position is placed. With new buildings one is already Prefabricated wall structure used as a mounting frame. An insulation layer is then on this board layer applied, preferably as an insulation mat is trained. Then the spacers placed, the longitudinal axis of which is transverse to the longitudinal axis of the Boards runs. This is followed by more Layers, it being preferred that a total of three Layers of boards, insulation layer and spacer slat layer be provided. On the spacer slat layer of the nth Layer is then a final board layer as Top layer applied. After forming this multilayer structure if it is pressurized, so that the insulation layers are slightly compressed be, with the provision that each insulation layer is compressed by about 5 to 10 mm. The so compressed multi-layer structure is then through suitable connecting means, such as clips or nails, fixed so that the pressure relief maintain structure imposed by the pressing process becomes.

In a final step, the wall element be cut to size, with the full-surface insulation layer and through the multiple subdivision practically no unfilled ones over the spacer slats Cavities can arise and also the required Strength is retained.

The wall element according to the invention can be used in particular advantageous as wall, ceiling or roof panels deploy.

Further advantageous embodiments of the invention are the subject of other subclaims.

Of course can also the floor and ceiling structures (Ground floor, upper floor) from the invention Truss are trained by a suitable Embodiment with compartment elements 4 is fanned out.

Fig. 2 shows the main components in schematic form of a framework. A framework for support a single compartment element 4 has two cross bars 6, 8 (upper chord, lower chord), which are the upper and lower Form the boundary of the framework. The two Cross bars 6, 8 are connected by vertical bars, wherein 2 only the left vertical bar 10 is shown. The right vertical bar has in principle the same structure as the vertical rod 10 and is only rotated by 180 ° around the longitudinal axis.

The bars 6, 8 and 10 have in common that they are one Show three-layer structure from three plank or board layers. Below are the planks of each layer referred to as floorboards, with the term "floorboards" - preferably made of weak wood - profiled wood are designated. Each rod 6, 8, 10 consists of one Central plank 12 and two outer planks 14, 16 on both sides the central plank 12 are arranged. The connection the planks 12, 14, 16 are made using suitable connecting means, such as nails or staples (Not shown).

As is apparent from Fig. 2, the front End portions of the outer planks 14, 16 of each cross bar 6 over the respectively adjacent end section of the Middle floor 12 extended so that the End faces of the crossbar 6 forms a central recess, the as slot 18 for a tenon / slot connection serves.

Depending on the width of the cross bar 6, the central plank can 12 still with one or more interruptions 20, 20 ', 20 '' are formed, these interruptions also as slots for receiving a pin for the Serve truss connection.

As further indicated on the upper cross bar 6, can the outer planks 16 with long cross bars 6 too are made from sub-elements 16a, 16b, which have a Gusset plate 22 are connected together.

This design variant also opens up the possibility use short sticks so that up to 70% of a barked tree, covered by the saplings Class II and III falls for the manufacture of the Truss can be exploited.

In the vertical rod 10 shown on the left in FIG. 2 is the central plank 12 opposite the two outer planks 14, 16 extended on both sides in the axial direction, so that through the protruding part of the central plank 12 each a pin 24 is formed, which on the slots 18 the end portions of the cross bar 6 is adapted.

The two outer planks 14, 16 are also in Transverse direction (transverse to the longitudinal axis) opposite the central plank 12 reset so that along the left (View according to Fig. 2) a longitudinal edge through the protruding Side edge of the central plank 12 formed longitudinal spigot 26 trains.

The framework frame schematically indicated in Fig. 2 can be put together easily by the Pin 24 of the side parts 10 in the associated slots 18 are inserted and then a corresponding fixation done by nails, screws or staples.

Since in the framework of FIG. 2 three more Slots 20, 20 ', 20' 'by comparatively short, to each other spaced central plank elements 12a, 12b, 12c and 12d can be formed in particular advantageous cut waste or very short small wood elements use as central planks.

FIGS. 3 to 6 show further exemplary embodiments shown for vertical bars that are in one have such a framework used.

Fig. 3 shows a vertical bar 28 in which the central plank 12 the two outer planks 14 and 16 on both sides protrudes in the longitudinal direction, so that on the front End sections in turn two pins 24 are formed. In contrast to the vertical rod 10 from FIG. 2, the Center plank 12 in relation to the outer planks 14, 16 in the transverse direction reset so that on the side edge of the vertical bar 28 forms a longitudinal slot 30 in that of the longitudinal pin 26 of the vertical rod 10 from FIG. 2 can immerse.

Fig. 4 shows a central rod 32 for a framework 2, wherein the central rod 32 in the Slots 20, 20 ', 20' 'is insertable. With such a Center bar 32 is only the center board 12 on both sides extended towards the two outer planks, see above that the pins on the front end sections Form 24 for insertion into the slots 20, 20 ', 20' '.

FIG. 5 shows the vertical rod 10 from FIG. 2 from a another direction, whereby - as already mentioned - this Vertical rod 10 to the left and right boundaries Truss frame can be used.

By assembling those shown in Figures 3 and 5 Vertical bars, i.e. by inserting the longitudinal pin 26 a corner element 34 can be formed in the longitudinal slot 30, as shown in Fig. 6. The vertical bars 10, 28 of the corner element 34 are by screw connections or other suitable connecting means put together.

On the formed by the vertical bars 10 and 28 Corner elements 34 are two contact surfaces 36 and 38 for the side edges of the partition element 4 are formed.

At the contact surface formed on the vertical rod 10 36 then includes one that is only indicated in FIG. 7 Compartmental element 4, which in turn can be up to one Central rod 32 extends according to FIG. 4.

On the contact surface 38 of the vertical rod 28 can be optimal a distance plank 40 can be provided to which again a compartment element 4 connects, its structure is described in more detail below. Between the distance board 40 and the partition element 4 or the contact surface 36 and the compartment element 4 can be a suitable one Intermediate layer, such as a mineral fiber layer or PU foam.

The upper end of the corner area shown in Fig. 7 takes place in turn by cross bars 6, with their Slits (18-20 ") pushed onto the assigned pin 24 become.

The partition element shown in Fig. 7 is with a Outer shell 45 provided, which are described in more detail below is described.

8, a corner area is three-dimensional from the Shown inside. Just like the one previously described Truss area is the corner element 34 through the vertical rod 10 with longitudinal pin 26 and a vertical rod 28 'formed with a longitudinal slot 30. The Vertical rod 28 'from FIG. 8 differs from the vertical rod 28 in Fig. 3 in that the two pins 24th are not designed so that the total height of the vertical rod 28 'is equal to the length of the central plank 12 of the vertical bar 10 is.

The pins 24 of the vertical rod 12 are in the assigned Recesses 20 of the lower left (Fig. 8) Crossbar 8 introduced. The horizontal one in Fig. 8 Cross bar 8 is flush with the contact surface 38 of the Vertical bar 28 'on. In the recess 20 'of this crossbar 8 the pin 24 of a central rod 32 is inserted, so that the partition element 4 between the central rod 32nd and vertical rod 28 and the upper (Fig. 8) surface of the Cross bar 8 can be inserted.

Fig. 9 shows an assembly table 44, with the help the vertical rods shown in Figures 3 to 5 and the cross bars 6 and 8 can be produced.

This assembly table 44 is made of square profiles in Cassette construction manufactured, with longitudinal profiles 46 and Cross profiles 48 together a support grid for the planks of bars.

On the end portions of the cross sections 48 are approximately End parts 50 running parallel to the longitudinal profiles 46 trained to 53.

These end pieces have two in parallel spacing and in Stop bars running in the longitudinal direction (parallel to the longitudinal profile) 54, 56, between which there is a space the wall thickness of a central plank 12 corresponds. The depth T of the stop bars 54 corresponds the length of the pin 24.

In order to be able to produce different rod lengths, the end parts 51 and 53 are slidable on the associated Cross sections 48 arranged.

When manufacturing the bars, an outer plank is first used 14 placed on the longitudinal profiles 46, the Length of the outer plank 14, the distance between the end parts 50 and 51 corresponds so that the end faces of the outer plank 14 rest on the stop bar 56. Then one Center board 12 in the direction of arrow Z between the two stop bars 54, 56 inserted until this in the predetermined Relative arrangement on the already positioned Outside board 14 is arranged. That is, in this reference position dip the two end sections of the center plank 12 in the space between the two stop bars 54 and 56 a. Then an outer plank 16 inserted between the end parts 50, 51, with reference to Center board 12 and positioned to the outer board 14 and then using suitable connecting means (glue, nail, Parenthesis). Through the framework of the invention it is ensured that the planks 12, 14, 16 are true to size and in the predetermined relative position to each other be trained so that no post-processing is required. To ensure angularity, the frame can also be provided with a transverse stop 58 against the long edges of the planks are feasible.

A first exemplary embodiment is shown in FIGS. 10 and 11 of a partition element 4 according to the invention.

10 shows an exploded view of a multilayer compartment element with three layers.

Each layer S consists of a board layer 60 which from a multiplicity of boards 62 lying against one another is trained, which in turn is made of small wood are. An insulation layer 64 is placed on the board layer 60, for example conventional mat-shaped insulation material from Rockwool® or natural substances, such as Sheep wool or straw slabs etc. applied. The insulation layer 64 can also with a Vapor barrier.

A large number are then on this insulation layer 64 of spacer bars arranged parallel to each other 66 placed, the longitudinal axis transverse to the longitudinal axis the board 62 runs. Connect to this layer S. then two further layers S 'and S ", which in turn have the same structure as layer S. The outer cover layer of the partition element 4 is by a final board layer 68 formed, the structure of the corresponds to other three planks of the partition element 4.

As already mentioned at the beginning, this multilayer structure compressed by a suitable pressing device and then by nails 71 or others suitable fasteners put together, these the boards 62, the spacers 66 and the insulation layer Enforce 64.

Since the insulation layer 64 is continuous, is the formation of cold bridges between the neighboring ones Board layers 60 reduced to a minimum, so that a excellent thermal insulation can be achieved. Because of the multilayer structure and the comparatively large Mass is created by the partition elements 4 according to the invention also achieved excellent sound insulation.

The finished partition element 4 is shown in FIG. 11, the outer cover layers being formed by the board layer 60 or the final board layer 68. As can be seen from FIG. 11, the insulation layers 64 are designed to be continuous, although a smaller layer thickness is established in the area of the spacer slats 66, but this only leads to a negligible deterioration in the insulation effect. By providing the spacer slats 66, small animals cannot penetrate into the spaces between the board layers 60, so that the disadvantages of the prior art in this regard are also eliminated. The compartment elements 4 can be produced in any size, a standard element having a length of 2400 mm, a width of 600 mm and a thickness (in the finished state) of approximately 190 mm. Such a partition element 4 has a weight of approximately 68 kg / m ² . The thermal transmittance value K is written compartmental element 4, so that further explanations can be dispensed with.

Fig. 13 shows an outer wall with the inventive Truss system is formed. That is, the Truss frame is laterally by two vertical bars 26, at its upper end section by a cross bar 6 and at its lower end by an invisible one Crossbar 8 determines the width of the truss is limited by center rods 24 which to the Cross bars 6, 8 are attached (see Fig. 2).

The truss fields formed in this way are fanned out by three compartment elements 4. Through the planks 68 of the three compartment elements 4 and the neighboring ones Side surfaces of the rods 6, 8, 26, 24 is a flush, largely flat outer surface defined on the a counter battens 74 is attached, which is transverse to the longitudinal direction the board layer 68 runs. On the counter battens an outer panel layer 80 is attached, the Joints of the outer panel panels covered by panels 82 that indicate a framework.

The contact surface can also be used to stabilize the bond for the counter battens 74 overstretched wind panicle bands 84 are applied, which in the case of FIG. 13 illustrated embodiment in the diagonal direction run.

FIGS. 14 and 15 show a roof element 86 which is formed from a plurality of partition elements 4, 4 ', 4''. The partition elements 4, 4 ', 4''are connected by panicle ribbons 84, which are applied to the cover layers formed by the board layers 60, 68. In turn, gusset plates 22 are provided on the side edges of the partition elements 4, 4 ', which at 2.76 W / m ² * K. The partition element corresponds to fire protection class F30.

This partition element 4 was also in the framework construction 8 inserted.

One of the outside planks 60, 68 can be provided with an outer shell 45 (see Fig. 7). The outer shell 45 can be made of chipboard, for example 70 (see Fig. 7) of counter battens arranged thereon 74 and panels 76 attached thereto, the joints of which are covered by butt plates 78. There such outer shells 45 already from the prior art are known, further explanations are unnecessary.

12 shows a further exemplary embodiment of a compartment element 4 according to the invention, for example for the formation of non-load-bearing, light interior walls can be used. With this light compartmental element 4, only one layer S is formed again from a board layer 60, spacer slats 66, one Insulation layer 64 and a final board layer 68 exists. In contrast to the previously described The insulation layer 64 is not an exemplary embodiment throughout the entire cross-sectional area of the board layer 60, 68 formed, but only between the adjacent spacer 66 so that in the area of Spacers no insulation is provided. Indoor is such a weakening of the insulation layer however acceptable. Each spacer 66 can be divided by two spacer bar elements 66 ', 66' 'lying one on top of the other become.

The manufacture of the partition element according to FIG. 12 is done in the same way as the one on the front side Squared timbers are attached. How in particular 15 shows the front end each compartment element 4 by two one above the other (View according to FIG. 15) arranged square timbers 86 ', 86' ' trained that together form a step or a joint. There are also two on the other end staggered squares 87 '. 87 '', the step on the right front side in Fig. 15 shows up (Fig. 15) while the level is on the left front side facing down, so that when Joining such compartmental elements on the face side 4 a joint-shaped contact section between two neighboring ones Compartmental elements 4, 4 'arises. The layer structure the compartment elements 4, 4 ', 4' 'can be in any way with one or more layers S according to those previously described Embodiments take place.

Such roof elements have the advantage that the inside the roof no longer needs to be boarded. On the board layer forming the outer wall then only has to another battens to hold the roof tiles or one other roof cover may be provided.

Of course, in a known manner on the a vapor barrier are formed on the inner board layer and a diffusion-open film on the outer board layer be applied so that optimal moisture insulation is guaranteed.

As is apparent from Fig. 16, the thus shaped Roof elements 84 between adjacent rafters 88 of a roof structure 90 inserted.

Insulating material can be placed between the planks of the bars and / or fire protection strips (fire protection behavior according to DIN 4102) can be inserted.

Another exemplary embodiment is shown in FIGS a compartment element 4 shown that usable in the manufacture of a wooden house according to FIG. 1 is.

With particularly high requirements, the bark edges can can also be edited.

This small wood board 98 is dotted along the dash-dotted line Line sawed apart in the middle in FIG. 18, see above that two board halves 94, 96 are obtained. The board half 96 is then 180 ° around its transverse axis (transverse to Longitudinal axis) rotated and so next to the other half of the board 96 placed that the bark edge 100 of the bark edge 99 is opposite.

By this rotation of the board half 94, the Compensate the taper of the small wood stick so that an almost rectangular board results, whereby by appropriate post-processing or alignment of the Bark edges 99 100 keep to predetermined dimensions to let. The one shown in Fig. 18 on the right side Element from the board halves 94, 96 thus gives one Transverse layer 91 with the layer boards 94, 96 of the partition element 4 according to FIG. 17. The parting line between the two bark edges 99, 100 can be made with insulating material if desired fill out. Usually, however, here a predetermined distance may be provided.

Due to the configuration of the transverse layer according to the invention 91 made of small wood boards 98 can be Use logs of over 70% to avoid such To create cross layers 91. This allows a high quality Compartmental element with minimal material and manufacturing effort are manufactured. The procedure according to the invention allows wind breaks and the like Wood to make to use high quality components.
