DETAILED DESCRIPTION

[0070] All the figures show at least parts of a wooden panel component designated as a whole by 1 in the form of a wooden panel construction wall. The wooden panel component 1 comprises a frame 2, which is composed of a total of four frame members 6 and 7, as well as 9 and 10, arranged opposite one another in pairs.

[0071] In an interior space 3 defined by the frame 2, that is to say within the frame 2, at least two layers and, in the exemplary embodiment of the wooden panel component 1 which is shown, a total of four layers 4 of cross-pieces 5 are arranged, which are aligned obliquely to two mutually opposite frame members 6 and 7 of the frame 2. Frame member 6 is a horizontally extending frame member which is at the top in the position of use of the illustrated wooden panel component 1. Frame member 7 of the frame 2 of the wooden panel component 1 is a lower frame member which extends horizontally in the position of use of the wooden panel component 1.

[0072] The cross-pieces 5 of the total of four layers 4 are connected to the two opposite frame members 6 and 7. The cross-pieces 5 can be connected to the two frame members 6 and 7 in a positive, nonpositive and/or materially bonded manner. A possible positive and/or nonpositive connection is, for example, a connection using nails, screws, pins, clamps, toothed lock washers and/or hardwood nails. A materially bonded connection of the cross-pieces 5 to the mutually opposite frame members 6 and 7 can be effected, for example, by adhesively bonding and/or gluing the cross-pieces 5 to the frame members 6 and 7.

[0073] The cross-pieces 5 each enclose an angle with the two frame members 6 and 7 which deviates from a right angle, that is to say is, for example, an acute or an obtuse angle. The acute angles which can be measured between the cross-pieces 5 and the frame members 6 and 7 are no more than 60°.

[0074] The construction of the wooden panel component 1 provides for the cross-pieces 5 of two adjacent layers 4 to be inclined at equal but opposites. This has the effect that cross-pieces 5 of the two adjacent layers 4 intersect in pairs at an intersection point 8. In the case of the wooden panel component 1 shown in the figures, cross-pieces 5 arranged adjacent to one another within a layer 4 of cross-pieces 5 are at a distance of 30.5 cm from one another.

[0075] The total of four layers 4 of cross-pieces 5 are arranged in different planes, parallel to a longitudinal extent of the two frame members 6 and 7, which are connected to one another by the cross-pieces 5, within the frame 2 and distributed over the entire depth of the frame 2.

[0076] The two opposite frame members 6 and 7 to which the cross-pieces 5 of the four layers 4 are connected are longitudinal members of the frame 2 of the wooden panel component 1. In this arrangement, frame members 6 and 7 are longer than the two other frame members 9 and 10 of the frame 2, which are aligned at right angles to frame members 6 and 7. The frame 2 thus has a rectangular shape. The two frame members 9 and 10 may also be referred to as transverse members 9 and 10 of the frame 2.

[0077] The figures make it clear that some of the cross-pieces 5 of the layers 4 within the frame 2 are arranged between one of the two horizontally aligned frame members 6 and 7 and one of the two shorter frame members 9 and 10 aligned perpendicular thereto, and are each connected thereto. This promotes additional stiffening of the frame 2 and the wooden panel component 1 equipped with it.

[0078] As has already been mentioned above, cross-pieces 5 of adjacent layers 4 intersect since the cross-pieces 5 of adjacent layers 4 are inclined in different directions. If required, intersecting cross-pieces 5 of adjacent layers 4 can be connected to one another at their respective intersection point 8. As already mentioned above, this can be effected in a positive, nonpositive and/or materially bonded manner.

[0079] FIG. 4, which shows a sectional view of the frame 2 of the wooden panel component 1 according to section line A-A indicated in FIG. 3, makes it clear that each layer 4 of cross-pieces 5 is connected to the frame members 6 and 7 in accordance with a grid 11 of retention points 12. Thus, each of the two frame members 6 and 7 has one such grid 11 of retention points 12 for fastening cross-pieces 5 of the individual layers 4 to the frame members 6 and 7. The retention points 12 of the individual layers 4 are provided in retaining depressions in the form of retaining grooves 13. The retaining grooves 13 are introduced transversely to the longitudinal extent of the two frame members 6 and 7 into the inner sides of the frame members 6 and 7 facing the interior space 3 of the frame 2.

[0080] The ends of the cross-pieces 5 project into the retaining grooves 13 at retention points 12 in order to fasten them to the frame members 6 and 7 in accordance with the grid 11 provided for them. The retention points 12 of the individual layers 4 are arranged offset relative to one another on the two frame members 6 and 7. The retention points 12 for fastening the cross-pieces 5 to the frame members 6 and 7 are thus distributed over the retaining grooves 13 introduced into the frame members 6 and 7. FIG. 4 shows that the cross-pieces 5 of the two inner layers 4 of cross-pieces are fixed in every second retaining groove 13. The retention points 12 of the cross-pieces 5 of the two outer layers 4 of cross-pieces 5 are arranged in the remaining retaining grooves 13.

[0081] Each grid 11 of retention points 12 has a pitch of 30.5 cm. This means that two adjacent retention points 12 of a grid 11 of a layer 4 of cross-pieces 5 are at a distance of 30.5 cm from one another. As a result, pairs of retaining grooves 13 in which the retention points 12 of the different grids 11 of the total of four layers 4 of cross-pieces 5 are arranged are at a distance from one another which corresponds to half the distance between two adjacent cross-pieces 5 of a layer 4 and to half the distance between two adjacent retention points 12 of a grid 11 and thus to a distance of 15.25 cm.

[0082] The wooden panel component 1 comprises two paneling elements 14 and 15, each of which is arranged on one side of the frame 2. Each of the two paneling elements 14 and 15 is fastened, on the one hand, to the frame members 6, 7, 9 and 10 of the frame 2 and, on the other hand, also to at least some of the cross-pieces 5 of at least one layer 4 of cross-pieces 5.

[0083] Interspaces 16 which may be present within the frame 2 of the wooden panel component 1, even after the layers 4 of cross-pieces 5 have been introduced, are filled, if required, with a filler 23, for example with insulating material. The frame 2 and the cross-pieces 5 of the wooden panel component 1 shown in the figures consist of wood or of a wooden material.

[0084] Boards made, for example, of concrete, gypsum, natural gypsum, clay, wood and/or wood fibers can be used for the paneling elements 14 and 15 on both sides of the wooden panel component 1. The use of OSB boards for the paneling elements 14 and 15 of the wooden panel component 1 is preferred.

[0085] The wooden panel component 1 described above can be produced by the method described below. Provision is accordingly made for a frame 2 of the wooden panel component 1 to be prepared first. This can be done on a production support not shown in the figures. A first layer 4 of cross-pieces 5 is then introduced into the frame 2. In this process, the cross-pieces 5 are aligned obliquely to two mutually opposite frame members 6 and 7 of the frame 2.

[0086] The cross-pieces 5 of the first layer 4 of cross-pieces 5 which has been introduced into the frame 2 are then fastened to the two oppositely arranged frame members 6 and 7 of the frame 2. The abovementioned retaining grooves 13 can be introduced immediately beforehand into the frame members 6 and 7. Alternatively, it is also possible to use frame members 6 and 7 into which the retaining grooves 13 have already been introduced at an earlier point in time.

[0087] In a further method step, at least one further layer 4 of cross-pieces 5 is introduced into the frame 2. In this process too, the cross-pieces 5 are aligned obliquely to the two mutually opposite frame members 6 and 7 of the frame 2. The cross-pieces 5 of the at least one further layer 4 of cross-pieces are then fastened to the two oppositely arranged frame members 6 and 7 of the frame 2.

[0088] If required, cross-pieces 5 of adjacent layers 4 of cross-pieces 5 can be connected to one another. The cross-pieces 5 can preferably be connected to one another at their intersection points 8. Interspaces 16 within the frame 2 can be filled with a filler 23, in particular with an insulating material 23. During this process, it is possible to introduce the filler in layers, for example in the form of insulating boards, or else as bound or unbound packing material.

[0089] In one embodiment of the method, provision is made for the frame 2 to be deposited on a paneling element 14 of the wooden panel component 1, which is to be produced in accordance with the method, in particular before a first layer 4 of cross-pieces 5 is introduced. The frame 2 can then be connected to the paneling element 14. The layers 4 of cross-pieces 5 can then be introduced into the frame 2. As soon as the frame 2 has been stiffened with the cross-pieces 5 of the different layers 4 and any interspaces 19 that may be present within the frame 2 have been filled with filler 23, a second paneling element 15 can be applied to that side of the frame 2 which is remote from the first paneling element 14 in order to close the frame 2 and thus the wooden panel component 1.

[0090] A preferred method for the production of the wooden panel component 1 can be explained with reference to FIGS. 6 to 10.

[0091] FIG. 6 shows continuous production of wooden panel components 1 from a continuous strand. During this process, a segment strand 27 of semifinished, still connected segments 24 of wooden panel components 1 is produced, and the segments 24 for the wooden panel components 1 to be produced are cut to the desired length from the segment strand 27. FIGS. 7 to 10 show enlarged detail sections of the overall illustration of FIG. 6.

[0092] In order to produce a wooden panel component 1, provision is made for at least two mutually opposite frame members 6 and 7 of a frame 2 of a wooden panel component 1 which is still to be closed to be provided first. Here, longitudinal members of a rectangular frame 2 of the wooden panel component 1 to be produced are preferably provided as frame members 6 and 7.

[0093] A first layer 4 of cross-pieces 5 is then introduced between the two frame members 6 and 7, wherein the cross-pieces 5 are aligned obliquely to the frame members 6 and 7. Cross-pieces 5 of the first layer 4 are then fastened to the two oppositely arranged frame members 6 and 7 of the frame 2.

[0094] In a subsequent method step, at least one further layer 4 of cross-pieces 5 is introduced between the two frame members 6 and 7, wherein the cross-pieces 5 are aligned transversely to the frame members 6 and 7. These cross-pieces 5 of the at least one further layer 4 are also fastened to the two frame members 6 and 7. All the aforementioned types of fastening can be used to fasten the cross-pieces 5 to the frame members 6 and 7.

[0095] The method steps explained above can be repeated until the intended number of layers 4 of cross-pieces 5 has been introduced between the two frame members 6 and 7 of the wooden panel component to be produced.

[0096] In the exemplary embodiment shown in FIGS. 6 to 10, a total of four layers 4 of cross-pieces 5 is introduced between the two frame members 6 and 7. In this case too, cross-pieces 5 of adjacent layers 4 of cross-pieces 5 can be connected to one another, if required. The cross-pieces 5 can preferably be connected to one another at their intersection points 8.

[0097] One special feature of the method illustrated in the figures provides that a plurality of frame members 6 and 7 are connected to one another to form two mutually opposite strands 21 and 22 of frame members 6 and 7. With the aid of the strands 21 and 22 of frame members 6 and 7, which are composed of a plurality of individual frame members 6 and 7, it is possible to produce wooden panel components 1 of virtually any desired length. For each strand 21 and 22, at least two frame members 6 and 7 are finger jointed to one another, as can be seen, in particular, from FIG. 7.

[0098] Before the layers 4 of cross-pieces 5 are introduced between the frame members 6 and 7, retaining depressions for the cross-pieces 5 in the form of retaining grooves 13 are milled into the frame members 6 and 7 in accordance with FIG. 7.

[0099] Interspaces 16 between the cross-pieces 5 of the individual layers 4 are then filled with filler 23. As indicated in FIG. 8, this can preferably take place in layers.

[0100] FIG. 8 illustrates that the cross-pieces 5 are introduced in layers, alternating with filler 23, between the frame members 6 and 7.

[0101] The frame members 6 and 7 connected to form strands 21 and 22 are arranged on a first paneling element 14 and connected to the paneling element 14. As the paneling element 14, a plurality of boards are guided in a butt-jointed manner on the production support, here on a transport means 26, for example on a conveyor belt or a roller conveyor.

[0102] As indicated in FIG. 8, the strands 21 and 22 of frame members 6 and 7 are arranged on the boards of the paneling element 14 before the layers 4 of cross-pieces 5 are introduced between the frame members 6 and 7.

[0103] It can be clearly seen that the layers 4 of cross-pieces 5 and the filler 23 between the strands 21 and 22 of frame members 6 and 7 are applied to or over the paneling element 14 in a way which spans the boards.

[0104] After the layers 4 and the filler 23 have been introduced in layers between the two strands 21 and 22 of frame members 6 and 7, the second paneling element 15 is applied in a subsequent method step and is connected at least to the frame members 6 and 7 and, if appropriate, also to the frame members 9 and 10 and/or the cross-pieces 5 of the outermost layer 4 of cross-pieces 5.

[0105] In the method illustrated in FIGS. 6 to 10, the application of the second paneling element 15 is provided as the last method step after a segment 24 for a single wooden panel component 1 has been separated from a segment strand 27 of still interconnected segments 24 of wooden panel components 1.

[0106] The production of the wooden panel components 1 takes place on a production support 26, which is only indicated in FIGS. 6 to 10. A transport means 26, which can be, for example, a conveyor belt, a roller conveyor and/or a transport trolley, serves as the production support.

[0107] To cut a segment 24 for a wooden panel component 1 to length, the strands 21 and 22 of frame members 6 and 7 are severed, after the introduction of the filling consisting of filler 23 and the layers 4 of cross-pieces 5, transversely to their longitudinal direction of extent. This method step is illustrated in FIG. 9.

[0108] In order to prepare the separated segment 24 for the subsequent production step, the filling consisting of cross-pieces 5 and filler 23 is removed at the separating cuts 25 of the segment 24 in accordance with a thickness of a transverse member 9, 10, which is connected to the frame members 6 and 7 in order to close the frame 2. In the exemplary embodiment shown according to FIG. 10, the filling is milled off, it being apparent that the lower paneling element 14 of the wooden panel component 1 is not cut back further during this process.

[0109] Further frame members 9 and 10, namely the already mentioned transverse members 9 and 10 of the frame 2, are then connected to the frame members 6 and 7 to form the closed frame 2. After this, as already mentioned above, the second paneling element 15 is placed on the frame members 6 and 7 and also the frame members introduced as transverse members 9 and 10 and is connected thereto (see right-hand half of FIG. 10 with the finished wooden panel component 1).

[0110] After the frame 2 has been provided with the paneling elements 14 and 15 on both sides, it is possible in all the abovementioned method variants for at least one wall opening 17, for example for a window and/or a door, to be introduced into the wooden panel component 1, for example by sawing. If required, the wall opening 17 can be fitted with a door frame or a window frame and/or with a functional element, for example with a door and/or a window and/or a roller shutter.

[0111] FIG. 5 shows an example of a wooden panel component 1 in the form of a wooden panel construction wall. The wooden panel component 1 from FIG. 5 has two wall openings 17. The wall opening 17 on the left in FIG. 5 is provided for a window and is bounded by a lintel member 18, a parapet member 19 and two jamb members 20. The right-hand one of the two wall openings 17 serves as a door opening and is bounded at the top by a lintel member 18 and laterally by two jamb members 20. The lintel members 18, the jamb members 20 and the parapet members 19 are made of wood and can therefore also be referred to as wooden lintel beams, wooden jamb beams or wooden parapet beams.

[0112] In a preferred embodiment of the above-described methods, individual or all the method steps are carried out by means of at least one robot.

[0113] The abovementioned wooden panel component 1 is suitable for use as an inner wall, outer wall and/or facing wall of a building, but also as a roof element, ceiling element and/or floor element of a building. The use of the wooden panel component 1 as a facing wall is particularly favorable for renovating existing buildings in a particularly efficient manner, in particular for renovating them for energy efficiency.

[0114] The invention relates, inter alia, to a wooden panel component 1 which has at least two layers 4 of cross-pieces 5 arranged within its frame 2. To stiffen the wooden panel component 1 and its frame 2, the cross-pieces 5 are aligned obliquely to mutually opposite frame members 6 and 7 of the frame 2.
