DETAILED DESCRIPTION OF THE INVENTION

(21) FIG. 1A illustrates a structural component, for example a wall formed by a single panel according to the prior art. FIG. 1B shows its behavior under loads, for example loads that may result from an earthquake or wind. FIG. 2A shows a wall according to the prior art formed by a series of panels which are not connected to one another in monolithic form. FIG. 2B shows the behavior under load, for example from an earthquake, wind or the like. As it can be derived from FIG. 2B, the individual panels allow a relative displacement/movement between the individual panels. This displacement could cause damage to the structure, e.g. by cracking or sagging.

(22) FIG. 3A shows a structural component 100 which was produced by a method according to the invention and is formed by a series of panels 1, 2, 3 which are connected via a series of connecting elements 7, 17 according to the invention. The panel is attached to another structure 102 or the like via tensile connections 101. FIG. 3B shows the behavior of the wall produced by the method according to the invention and shows the monolithic behavior when subjected to a force 103. The monolithic behavior gives the wall high rigidity, reducing damage due to earthquakes and similar exposed buildings and allowing the number of connections 101 to be reduced.

(23) FIGS. 4A and 4B show a floor produced according to the invention, indicating the forces 103 in FIG. 4B to which the individual panels are exposed and the connections made by the connecting element 7 according to the invention. The monolithic behavior of the floor makes it possible to reduce damage to the building due to an earthquake or the like.

(24) For the execution of a method according to the invention, cavities 20, 20a and 20b are made in timber panels 1, 2, 3 are created in a first step, in particular in panels XLAM or CLT or the like, on one of the surfaces 4, 5 of the panels 1, 2 which match and form the wall to be created, 2, 3.

(25) In one embodiment, these panels consist of at least three panel layers or boards. The panel layers are superimposed and connected to one another so that the fibers of each layer 21, 22, 23, 24 and 25 in the panel plane are rotated by 90° with respect to the adjacent layers, or in general the panels are made of lamellar timber.

(26) These cavities 20, 20a and 20b are produced, for example, by means of a CNC or else via a portable machine at the construction site, which mills a recess or opening on the adjacent edges of the panels 1, 2, 3, and thereby forms the cavities. The cavities 20, 20a and 20b are not continuous for panels of larger width in the direction perpendicular to the surface of the wall. In these cavities 20, 20a and 20b, the connecting element 7, 17 is pressed, which is formed by a metal element or a fiber-reinforced polymer, which has a series of ribs 7a, 7b, 7c, 7d, 7e which are parallel to the plane of the panel and which are advantageously arranged in relation to each of the timber ply 21, 23, 23, 24 and 25 forming the panel 1, 2, 3. In one embodiment, for example, five ribs are present, including the bottom surface of the connecting elements 7, 17. These ribs 7a, 7b, 7c, 7d, 7e can be dimensioned depending on the orientation of the timber ply. The ribs with the most load can be formed with a greater thickness in order to withstand better or if the panel should only be made up of three layers, the connecting element can also have five ribs 7a, 7b, 7c, 7d, 7e. In this case, two ribs work together to absorb the stresses of a timber ply 21, 22, 23, 24, 25.

(27) After insertion, the connecting element 7, 17 is inserted without play in the direction perpendicular to the connecting surface. After insertion of the connecting element 7, 17, the screws 11 are screwed into the seats 12 of the connecting element in order to clamp the two panels 1 and 2 with one another without play and to create a monolithic structure. The fastening is supported with the clamping by anchoring the screws, the vertical joint between the panels and the introduction of a foam. A plurality of connecting elements 7, 17 are advantageously used to connect the panels 1, 2.

(28) The connecting screws advantageously have an inclination of essentially between 30° and 70°, preferably 60° (whereby essentially means +−5°). Advantageously, they can also be introduced in such a way that at least two timber layers 22, 23 are stressed with different orientation of the timber fibers. This ensures greater resistance to stress.

(29) Advantageously, the seats 12 have a groove for receiving screw heads/clamping elements 11.

(30) As shown in FIGS. 14A, 14B, 14C the gap 8 is present during the insertion of the connecting element 7, 17 and with the introduction of the screws 11 and their clamping by means of anchoring, FIG. 14C shows how the gap 8 is closed and the two timber panels therefore have a monolithic behavior.

(31) In a second step, an insulating agent, for example a polyurethane foam, a resin or the like, may be introduced in order to isolate the connection. This insulating means can also support the fastening of the connecting elements 7, 17.

(32) The connecting elements are preferably hollow with ribs arranged in the inside in order to give the element greater rigidity, wherein the entire element remains light. Advantageously, the connecting elements are made of metal, in particular aluminum, by extrusion or extrusion from reinforced polymer.

(33) The connecting element 7, 17 preferably has a wedge shape in order to facilitate insertion into the cavity 20. In particular, only the end part of the connecting element 7, 17 is wedge-shaped, i.e. the first part that is introduced.

(34) The openings of the connecting elements 7, 17 are advantageously filled with the insulating material.

(35) In the subsequent step, a tape/adhesive tape is attached to the opening 20 such that the connection is sealed. Advantageously, the tape is glued on both sides along the entire contact area of the panels. This also seals the gap between the panels that might be present. The tape can be an adhesive tape provided for air sealing.

(36) In a preferred embodiment, the cavity 20, 20a, 20b is preferably closed in timber before the tape 20 is laid by means of a closure element, for example a plug.

(37) A structural component produced by such a method and with an element according to the invention has considerable advantages, since it can be assembled with panels with standard dimensions and still maintains the characteristics of a single panel. This structural component is not only more economical to manufacture because standard panels can be used, but is also easier to transport.
