DETAILED DESCRIPTION

[0042] The flat wall 1 shown in FIGS. 1 and 2 is built with a wall system according to the present disclosure and is composed of parallel vertical wooden beams 2 with a length A and a breadth B and which are, for example, made such that they are dimensionally stable lengthways without significant expansion or shrinkage lengthways.

[0043] In this case the beams 2 extend parallel to each other lengthways and their side edges 3 are mounted opposite each other breadthways, whereby these side edges 3 are provided with a tongue 4 and groove 5 with which the beams laterally fit into each other, possibly with a certain lateral clearance 6, as shown in FIG. 11, depending on the humidity of the surroundings.

[0044] The beams 2 are provided with passages 7 with a diameter D at a centre distance C from each other which extend over the breadth B of the beams 2 according to an axial passage direction X-X′ and which in a mounted condition of the wall are located in each other's extension in two or more continuous transversal channels.

[0045] An anchoring element 8 is mounted in every passage 7 at a fixed depth E from the side edge 3 of the beams 2.

[0046] In the case of the FIGS. 3 to 6, the anchoring elements 8 are executed as a screw-in sleeve with length F provided with a rough exterior thread 9 with outer diameter G which is bigger than the inner diameter D of the passages 7 and a smooth inner wall 10 with inner diameter H.

[0047] In some embodiments, the anchoring elements 8 are premounted in the passages 7 by screwing them axially in the passages 7 with a powerful screwdriver, for example provided with an Allen key head which fits in a complementary non-round recess 11 in the inner wall 10 of the anchoring element 8.

[0048] The wall system is further provided with spacers 12 which are mounted across the passages 7 between the anchoring elements 8 to keep them at a fixed distance L and to fix them.

[0049] In this case, the spacers 12 are executed as rods with a body 13 with said length L and in this case a hexagonal cross-section with a defined circle, the diameter M of which is approximately equal to the inner diameter D of the passages 7.

[0050] The body 13 has a front end on which a threaded rod 14 is coaxially mounted with a diameter K which is approximately equal to the inner diameter H of the anchoring elements 8 and which is less than the diameter M of the defined circle of the body 13, this to form a front stop surface 15.

[0051] The threaded rod 14 has a length N which is divided into a cylindrical section 14′ with length N′ from the foot of the threaded rod 14 and a section 14″ with length N″ provided with fine thread 16 with an outer diameter equal to or less than the diameter K of the cylindrical section 14′.

[0052] The rear end of the body 13 is cut straight to form a rear stop surface 17 and is provided with an axial bore 18 with length P provided with thread 18 which is complementary to the thread 16 of the threaded rod 14, such that the threaded rod 14 can be screwed in the bore 17.

[0053] In some embodiments, the length N of the threaded rod 14 is less than the sum of the axial length F of the screw-in sleeve 8 and the length P of the bore 18 and the length N′ of the smooth section 14′ is equal to or less than the length F of the anchoring element 8, all this such that the threaded rod 14 can be screwed sufficiently deep through the anchoring element 8 in the bore 18 with clamping of an anchoring element 8 between the front stop surface 15 of the spacer 12 on one side and the rear stop surface 17 of the spacer 12 on the other side of the anchoring element 8 as shown in FIG. 5.

[0054] The dimensions of the hexagonal cross-section of the body 13 of the spacers are such that a standard key fits over the body to screw two spacers into each other with clamping of the anchoring element 8. Other solutions for the use of a screwing tool are evidently not excluded.

[0055] It is not excluded to apply a screw fitting between the spacers 12 and the anchoring elements 8 for which no tools are required, like in the case of a kind of a bayonet fitting wherein de parts of the bayonet fitting have to be turned for instance over half a turn in respect to each other.

[0056] FIG. 6 shows a situation whereby the side edges 3 of two identical beams 2 are mounted opposite each other with a wall system according to the present disclosure with a series of identical anchoring elements 8 and identical spacers 12.

[0057] The anchoring elements 8 lie with their centre on a regular rectangular node pattern with nodes 20 as shown in FIG. 7, this thanks to the fixed distance L between the spacers 8, the fixed length F of the anchoring elements 8 and the dimensional stability of the centre distance C between the passages 7 in the beams 2 due to the dimensional stability of the beams 2 lengthways.

[0058] The diagonal distance between the nodes 20 is therefore fixed, which ensures the strut rigidity of the wall system because the beams 2 are attached as it were to the nodes. The relative position of the beams 2 is therefore fixed, regardless of the swelling or shrinkage of the beams 2 breadthways B as a result of increasing or decreasing humidity.

[0059] The length L and F are chosen such that in the event of the highest wood humidity of the beams 2 and therefore the greatest swelling of the beams 2 breadthways B, a minimum clearance S and S′ always remains between the beams, possibly taking into account the presence of a mounting bracket that may be present in the clearance between the beams 2. This length can depend on the thickness of the wood and the type of wood which does not necessarily have to be solid wood, but can also be laminated wood or plywood or another type of wood.

[0060] To disassemble the wall 1, the spacer 12 at one end of the wall 1 can be loosened, while the spacer 12 at the other end of the wall 1 is held to stop it rotating. It is always the first spacer 8 that comes loose without the anchoring elements 12 loosening and therefore without damaging the passages 7. The beams 2 with the premounted anchoring elements 8 can therefore be reused for a new wall.

[0061] The wall system according to the present disclosure is delivered on site as a modular construction kit with: [0062] a series of wooden beams 2 which breadthways B are provided with passages 7 and premounted anchoring elements 8 in the passages 7 which are anchored in the passages 7 in the beams 2; [0063] the necessary spacers 12 with a fixed length which can be fittingly slid and rotated in the passages 7.

[0064] FIGS. 8 and 9 show a variant of an anchoring element 8 and a spacer 12 made in one piece from metal or the like.

[0065] In this case the spacer 12 is executed as a rod or tube with at one end an exterior thread 16 and at the other end a complementary internal thread 19 and a pinion mounted on the tube which serves as anchoring element 8, for which purpose this pinion is provided with holes 21 to be able to screw the pinion against a side edge 3 of a beam 2 with screws 22 and therefore anchor it on the beam axially and against rotation.

[0066] In this case the anchoring elements in the construction kit will not be premounted on the beams 2.

[0067] FIG. 10 is variant of the embodiment represented in FIGS. 8 and 9, whereby in this case the body 13 of the spacer 12 is provided with a hole 21 in the form of a bore 21 at the extremity of the spacer 12 with the anchoring element 8, which bore 21 encloses an angle T with the axial centreline of the spacer 12 of for instance 40°.

[0068] The bore 21 is meant for anchoring the spacer 12 with its anchoring element 8 with regards the passages 7 in the beam 2 in axial and in rotational direction by a single screw 22 which is screwed in at an angle. That way a connection is realised that fulfils the requirements of a Eurocode connection.

[0069] It is clear that more than one such angled screw could be applied and whether or not in combination with screws 21 like in FIG. 9.

[0070] FIG. 11 shows yet another embodiment of a wall system 1 according to the present disclosure which is composed of beams 2 which are connected to each other with a lateral clearance 6 between the side edges 3 by anchoring elements 8 which are kept at a distance L from each other by spacers 12 which extend through passages 7 which connect the side edges 3.

[0071] Flexible compressible seals 23 are mounted between beams 2 which seal the gap between the beams 2 to stop wind and rain.

[0072] In this case the spacers 12 have a body 13 with a hexagonal cross-section and at one end are provided with a coaxial threaded rod 14 with exterior thread 16 and at the other end a coaxial bore 18 with corresponding internal thread 19.

[0073] In this case the anchoring elements 8 are formed by separate plates as shown in FIG. 12 with a central passage 24 for the threaded rod section 14 of the spacers 12 and holes 21 for screws 22 with which the plates can be screwed in the groove 5 as shown in FIG. 10.

[0074] Before mounting, the plates 8 are screwed in the grooves 5 of the beams 2 with the central passage 24 in line with the passages 7 in the beams 2.

[0075] Subsequently the beams 2 are mutually attached to each other one by one by the spacers 12 which are inserted with their threaded rod section 14 forward through a passage 7 in the last beam 2 and through the central passage 24 of the plate 8 of the last beam and subsequently are completely tightened with the threaded rod section 14 in the thread 19 of the bore 18 of the previous spacer 12.

[0076] The length of the body 13 of the spacers 8 determines said fixed distance L between the anchoring elements 8 whereby the body 13 is clamped with its stop surfaces 15 and 17 between two consecutive anchoring elements 8.

[0077] Instead of the plates being attached in the grooves 5 it is not excluded that the plates are mounted against the end of the tongues 4.

[0078] It is understood that the plates can be attached in any other way on the beams 2.

[0079] The present disclosure is not limited to the embodiments described as an example and shown in the drawings, but a wall system according to the present disclosure and accompanying construction kit can be realised in all kinds of forms and dimensions, without departing from the scope of the present disclosure.
