(20) FIG. 22 shows a three-dimensional structure created by means of connection elements and building elements.

(21) A connection element 1 consists of a body. This body comprises a case 2 and contains filling material 3 within said case.

(22) The connection element 1 is formed so as to be able to house a through anchoring element 10. The connection element is fixed onto the external surface of the building component, opposite the surface. This through anchoring element 10 can be a screw for example. The anchoring element 10 passes at least through two walls 2a, 2b. In this way, the case 2 makes the connection stiff, while the filling 3 provides the connection with elastic resistance. Moreover, the filling material 3 allows the fixing of the anchoring element 10 along the entire passage area within the connection element 1. The anchoring element 10 is inserted into the building component 100 which can be a wooden panel for example. Advantageously, the anchoring element or the anchoring elements are inserted inclined so as to guarantee better fixing. The anchoring element can be inserted into the connection element 1 according to the invention in appropriate holes or it can create a hole for example. The hole where the anchoring element 10 is inserted can also be threaded.

(23) In a further embodiment, the case can be empty and only after fixing the anchoring element or the anchoring elements both to the connection element and to the panel 100, the space 3 is filled with a resin for example.

(24) In a different embodiment, the space 3 is filled with wood or a wood composite for example. In a further embodiment the case can be empty and contain a second body having some compartments which will be filled with a resin for example only after fixing the anchoring element or the anchoring elements.

(25) In a further embodiment, the case can be empty and contain a body having compartments in which capsules are located which are drilled and crossed by the anchoring elements. The connection element 1 can have gripping points to facilitate the movement of the panel 100 with the connection element 1.

(26) Moreover, in one embodiment there may be gripping points which allow the fixing of other connection elements by means of a connection element such as for example a poly-orthogonal plate, so as to be able to securely connect a series of panels 100 and/or building components.

(27) The building component can be a wooden component and/or a component consisting of several layers forming a multilayer called sandwich panel. The connection element 1 according to the invention can be connected for example to an already existing external element such as for example an element arranged in a concrete foundation or steel beams already existing in the building.

(28) The connection element can also connect two beams for example, being arranged on the end part of the beam. In this way, the connection element can create a concealed connection, that is, there should not be any laterally projecting elements from the connection. This allows all stresses to be within the beam section. In this way, the beams can be better sized. Moreover, the load is arranged within the section of the beams.

(29) As shown in FIG. 5, the beam-beam connection can be aligned or inclined. In FIG. 5 there is a connection means 20 which connects the two connection elements 1 which are fixed by means of anchoring elements 10 onto the building element 100.

(30) In FIGS. 6 and 7 a connection element 1 is shown fixed onto the building element 100. The connection element 1 has the shape of an M closed at the bottom and connection means 20 are connected onto it, particularly a folded plate so as to adapt to the shape of connection element 1.

(31) The connection element also allows other building elements to be easily fixed. For example, a ceiling can be easily connected to the junction between the two beams.

(32) Finally, the connection element according to the invention allows the anchoring elements to be oriented in any way ensuring excellent fixing at the same time.

(33) The connection element according to the invention can be used to connect wooden panels or panels consisting of several layers of wood, beams, wooden beams or also other elements, such as for example concrete and reinforced concrete panels, multi-layer panels or polymeric panels.

(34) The anchoring element 10 can consist of wood screws or resin-coated bars if the connection element is used on wooden building elements or can consist of reinforcement bars if the connection element is used on building elements made of reinforced concrete.

(35) In order to easily and rapidly produce the case, an extrusion process can be used, for example. From the thus obtained extruded profile the connection element according to the invention is later cut to the required width.

(36) The case 2 can be also formed by folding a sheet for example a metal sheet.

(37) FIGS. 8, 9, 10 and 11 show embodiments of the connection element according to the invention. FIG. 9 shows a connection element 1 fixed to a panel 100 by means of anchoring means 10. The case 2 is M-shaped with a closed bottom. The filling material does not completely fill the case 2. For example, openings 11 are provided. These openings can be used for example to fix means adapted to move the connection element 1 with the panel 100 or they can simply be used to save material, but they can also be used to discharge the shavings generated while inserting the anchoring element 10 or while performing the threading.

(38) FIGS. 12 and 13 snow a connection element 1 fixed to connection means 20 by means of fixing means 21. This fixing means is for example a bolt which can screw both plates; working only from the inside of the building it is possible to obtain a connection with mechanical ductility characteristics since the bolt 21 is lathed in the central area and it is further possible to eliminate any clearance of the bolt hole using an eccentric tube or a resin capsule interposed between the bolt 21 and the filling material 3.

(39) FIG. 14 shows a connection between a beam with a connection element fixed on the building element 100 and a second building element.

(40) In a further preferred embodiment, the filling material 3 can be wood or compressed wood chipboard.

(41) FIG. 11 shows a further embodiment of connection element 1 according to the invention. The element according to this embodiment is split into two different chambers; in each chamber anchoring elements 10 are arranged. Between the two chambers, a housing for a connection means 20 is interposed. This housing for a connection means 20 is fixed by means of fixing means 21 by closing also the two parts of the connection element.

(42) FIGS. 17 and 18 show a further embodiment, with the housing for the connection means 21 located in the chamber of the connection element 1 and clamped with the fixing means 21.

(43) FIGS. 19 and 20 show an element according to FIGS. 17 and 18 with a connection means 20. This connection means is fixed to the housing. In this way the connection is more stable and secure.

(44) FIG. 21 shows a connection of two connection elements according to the invention connected to each other by means of a plate 20 and with a series of anchoring means 10 fixed on building components (not shown).

(45) FIG. 22 shows a three dimensional structure created by means of the connection element 1 according to the invention connecting a series of building components 100 whose centre is a plate 20.
