The weakness of said known solid wood elements is that the wood elements 'warp' in relation to one another, which results in uneven absorption and distribution of displacement forces at the edges of the building elements where these are built together. To overcome said disadvantages, there is provided a solid wood element (2) of the kind disclosed which has at least one groove (18) in the ends, transversely to the ends (16) of the wood elements in the production direction of the solid wood elements, in which groove (18) there is placed a co-operating tongue (20) in the form of at least one bracing element which is fastened in the groove, and which extends along the whole length of the groove(s). Mutual warping between the wood elements (4) is hereby opposed.

Description

Title: Solid wood building element system.
The present invention concerns a solid wood building system in particular for use as supporting rear walls in outer walls, supporting dividing walls, non-supporting dividing walls, roof elements and storey partitions, and comprising elements of solid wood consisting of parallel boards which are assembled broadside against broadside by nailing together, by means of dowels or by gluing, where the thick- ness of the individual solid wood element is defined by the breadth of the used boards, the length of said solid wood element corresponding to the length of the boards, and the breadth of said solid wood element having an extension defined as the sum of the narrow sides of the boards used therein.
The weakness of the known elements of solid wood is that the wooden elements "warp" in relation to one another, which results in an uneven absorption and distribution of displacement forces at the edges of the building elements where these are built together. This "warping" will also have the result that when the elements are assembled side by side, for example in the formation of a wall construction, they will not form a wall surface which is straight and of attractive appearance. The object of the invention is thus to provide a building element system of the disclosed kind, where the edge construction on all element types is able to absorb and distribute displacement forces at the edge areas of the building elements when these are built together, and also to neutral- ise the warping of the wood during moistening and drying out in use.
This object is achieved with a system of solid wood elements which are assembled by being nailed together, or by means of dowels or by gluing, which is characterised in that the solid wood element has at least one key groove respectively in the very ends and transversely to the ends of the boards in the breadth direction of the solid wood elements, in which key groove there is placed a co-operating tongue in the form of at least one relatively stiff bracing element extending through the whole of the key groove (s), and which is fastened in the groove by securing means .
It is hereby achieved that displacement forces arising in the building together of elements of solid wood, and the building together of solid wood elements with other building components, are distributed uniformly, whereby the forces can be transferred/absorbed by means of simple fastening means such as nails, screws, wooden dowels etc.
Moreover, the solid wood element according to the invention will not alter the projected form and size by shrinkage and swelling, despite moistening and drying out in production or during use in the building phase.
Of further advantages achieved with the solid wood element according to the invention, it can be mentioned that with the drying out of the elements during production and during the building phase, warping in the edge of the solid wood elements as a result of the use of non-uniform wood will be absorbed and distributed uniformly to the fastening means for the bracing element (s) placed in the groove (s) . With the object of protecting the solid wood element against moisturising, and for the improvement of the bracing in general, the tongue can comprise an edge plate extending along the whole breadth of the solid wood element.
Unintentional moistening of the solid wood elements in the building phase is hereby compensated for, while at the same time a uniform drying out of the elements is ensured without the formation of strength-reducing cracks.
In the following, the invention is explained in more detail with reference to the drawing, where fig. 1 is a perspective view of a solid wood element according to the invention with tongues with edge plate for use as wall element, fig. 2 is an end view of the solid wood element shown in fig. 1, fig. 3 is an end view of the solid wood element shown in fig. 4, fig. 4 is a perspective view of a solid wood element according to the invention with tongues without edge plate for use as wall element. fig. 5 is a perspective view of a solid wood element according to the invention with tongues with edge plate for use as storey coverage element, fig. 6 is a side view of the solid wood element shown in fig. 5, fig. 7 is a perspective view of a solid wood element according to the invention with tongues without edge plate for use as storey coverage element, fig. 8 is an end view of the solid wood element shown in fig. 7, fig. 9 is a perspective view of the solid wood elements according to the invention used in a building construction, and fig. 10 is a detailed end view of an example em- bodiment for the assembly of solid wood elements which are used as wall cladding or as storey partitioning.
In the following, the solid wood elements according to the invention are described with reference to all of the drawing fig. 1 to fig. 8. Figs. 1-4 show solid wood elements 2 for use as wall cladding or as room dividers, and figs. 5-8 show solid wood elements 2 for use as storey coverage elements, but since the principles and construction of the elements are the same, the same reference numbers are used for the sake of clarity.
The solid wood element 2 in the shown embodiment is built up of rectangular, solid wood elements 4 (boards) , the opposing side surfaces 6 of which are fastened to one another by securing means 8 in the form of nails, screws, dowels and/or glue, so that in combination the side edges 10 of the wood elements 4 form the front and rear surfaces 12, 14 of the solid wood elements, and the breadth B of the solid wood element 2 corresponds substantially to the sum of the thickness t (the narrow sides) of the wood elements (boards) which form the solid wood element 2.
As will appear from figs. 2, 4, 6 and 8, the ends 16 of the wood elements in the solid wood elements 2 comprise a groove 18 which extends along the whole breadth B of the solid wood element, and in which there is fastened a bracing element 20 in the form of a tongue which is secured to the inside surfaces 22, 24, 26 of the groove by not shown means such as nails, screws, dowels and/or glue. It is hereby achieved that possible mutual warping of the wood elements 4 (boards) forming the solid wood element 2, arising as a result of moisturising and drying of the wood, is compensated for, simply because the bracing element 20 anchored in the groove 18 prevents a relative displacement between the wood elements 4 (boards) .
As will also appear from figs. 1, 2, 5 and 6, the bracing element 20 can also comprise edge plate 28, which similarly with known fastening means such as nails, screws, dowels and/or glue is secured to the ends 16 of the elements forming the solid wood element 2. There is hereby achieved a further prevention against relative displacement between the wood elements 4 in the solid wood element 2. Moreover, there is achieved an improved absorption of the displacement forces between the wood elements 4 ( boards) which form the solid wood element 2.
With the use of solid wood elements 2 as storey coverage elements, it will be obvious that the solid wood elements 2 are oriented with the wood elements so that these are supported in the areas at the end edges 16.
In fig. 9 it is shown how the solid wood elements 2 according to the invention are used as building elements, namely for use as supporting rear walls 30 in outer walls 31, supporting dividing walls 32 and storey partitions 34 respectively. As shown, when the solid wood elements 2 are used as wall elements 30, 32, they are arranged standing on the edge plate 28 which is placed on the floor or foundation 35 of the building construction. As will further appear from fig. 10, the solid wood elements 2 are assembled at opposing longitudinal-side edges 36, 36' by assembly lists 38, 39. On each longitudinal edge 36, 36' , each solid wood element 2 thus comprises an assembly list 38, 39 which lies flush with the front 12 and respec- tively the rear 14 of the solid wood element 2. The assembly of successive wall elements 2 thus takes place by the elements being raised, standing on the edge plate 28 with the opposing sides 40, 40' of the assembly lists 38, 39 in abutment with each other, and in contact with the parts 42, 42' of the opposing longitudinal sides edges 36, 36' , which are not covered by the assembly lists 38, 39, after which the solid wood elements 2 are assembled by the driving of mechanical assembly means into the assembly lists 38, 39 for the mutual securing of the solid wood elements 2. The same assembly principle is used when the solid wood elements 2 are used as storey partitions 34, cf. fig. 9.
