CONNECTION SYSTEM

Description

2 For joining wooden structures where the joint must be able to withstand relatively little load and where aesthetics are of particular importance, wood-to-wood joints are often used, whereby, for example, a mortise and tenon joint, a dowel joint, or the similar is applied, with or without the aid of glue or another adhesive. However, such wood-to-wood joints5 have a few important disadvantages: realizing such joints is slow and requires solid craftsmanship. In applications where stronger connections need to be achieved or where speed of installation is important, use will generally be made of an external connection mechanism, such as a nail connection, a screw connection, or corner anchors or the like to fasten the wooden structures together firmly and quickly. Such connections are often used in timber frame construction, for example for the construction of prefabricated houses. However, there are a number of disadvantages with the already known connection mechanisms.Firstly, many such connection mechanisms are not aesthetically pleasing and are often conspicuous, such as metal corner anchors or reinforcement angles. Secondly, the recyclability of wood connections is becoming increasingly important, so that wood connections can be reused circularly. Consequently, many of the less recyclable connection mechanisms, such as nail connections, are being used less and less. In addition, it is also important that this recycling takes place without the connection mechanisms being damaged, so that they are circularly reusable. There already exist a number of connection mechanisms that are relatively invisible and recyclable, but these connection mechanisms are often designed for very specific applications and are therefore not universally usable throughout the BE2025 / 5086 3 timber construction. A third major disadvantage of the known connection mechanisms is therefore that they are always aimed at a very specific goal, such as the use ofnails or screws for fastening panels to a larger structure, or the use of corner anchors for corner joints… To make the right choice, it is always necessary to consider the tensile stresses, the shape of the wood structures, the strength of the wood… There are mechanisms that can be used quite universally, such as very thick bolts, but such mechanisms are often aesthetically visible and disruptive. 10 The goal of this invention is to provide a circular and recyclable connection system that can be used more universally and to connect other already known connection systems for wooden structures with each other. In addition, the goal of the invention is also to provide a connection system that is virtually invisible compared to existing connection systems. 15 The goal of this invention is achieved by providing a connection system to connect wooden structures with each other into a connected state, comprising: -a first wooden structure with at least a first surface,-a second wooden structure with at least one first plane,20 -a first connection mechanism to connect the first plane of the first structure and the first plane of the second structure mutually by means of a: connection element with a first part element a second part element, which is provided in the connected state to the first25 part element, whereby the first part element is incorporated in the first structure in the connected state and whereby the second part element is incorporated in the second structure in the connected state; o first blocking mechanism, which prevents the first part element in the connected state from being moved relative to the first structure. 30 of the first structure, where the first recess in the connected state receives the first sub-element, that the first blocking mechanism and a first end elementcomprises with a connecting part and a head, where the connecting part is executed as a rigid elongated part that is incorporated into the first structure in the connected state and the heads connect the first part element to each other, that the first blocking mechanism further comprises a first retaining element that prevents the head10 of the first end element in the connected state from being moved toward the first part element and where the first recess in the connected state prevents the first part element from being moved toward the head of the first end element, so that the first retaining elements and the first recess together prevent the first part element in the connected state from being moved toward the first structure. Due to the cooperation of the recess holding the first sub-element and the first holding element holding the head of the first end element, the first sub-element, which is connected by means of the rigid connecting part of the first end element to the head of the first end element, will be blocked andrelative to the first structure. Due to the large contact surface between the recess and the first element, it is possible to achieve a particularly strong locking mechanism. Moreover, there is a great deal of flexibility regarding the second locking mechanism. Thus, in certain design forms, it is possible to provide an identical locking mechanism to achieve a particularly strong connection, or in other design forms, it is also possible to provide alternative locking mechanisms. Through the combination of the flexibility and strength of this connection mechanism, it is possible to achieve a very universally applicable connection mechanism.30 BE2025 / 5086 5 The design forms according to the invention are also not visible because the core of the first locking mechanism is provided entirely internally within the wood structure: both the first element and the connection part can be placed entirely inside the first structures and / or the hidden recess between the two. wooden structures are placed, whereby only the head of the first 5 remainsend element or the first retaining element interacting with it may still be visible, as is the case, for example, with a bolt connection or a nail connection. In addition, such a connection mechanism is also highly recyclable, since it is possible to reuse all elements of the connection system in another connection according to the invention.10 Such a connection system is even fully circularly reusable, since the elements of the connection system are not damaged during this reuse. The wooden structures are preferably wooden beams, but can just as well be boards or similar made of a wood-based material.15 The first part element and the second part element can be permanently connected to each other. In an alternative form of execution, it is also possible that they are inextricably connected to each other. The heads and the connecting part of the first end element can be permanently connected to each other, but can alternatively also be inextricably connected to each other.20 The heads and / or the first part element can be provided withare at one end of the connecting part, but this is not necessary. Preferably, the second structure comprises a second recess that opens into the first plane of the second structure, whereby the second recess in the connected state accommodates the second sub-element, whereby the second locking mechanism comprises a second end element with a connecting part and a head, where the connecting part is executed as a rigid elongated part that is incorporated into the second structure in the connected state and the head connects the second sub-element to each other, that the second locking mechanism further comprises a second retaining element that prevents the head of the second end element in the connected BE2025 / 5086 6 state from being moved towards the second end element and whereby the second recess in the connected state prevents the second sub-element from being moved towards the head, so that the second retaining element and the second recess together constitute the second sub-element in the connected state prevent being moved in relation to the second structure. Through the 5By combining the first locking mechanism and the second locking mechanism, it is possible to realize an extremely strong connection system that is moreover invisible. Naturally, both the second element and the second locking mechanism can exhibit all the characteristics of the first element and the first locking mechanism respectively, as described in all possible embodiments according to the invention. Alternatively, it is also possible that the second locking mechanism comprises a known screw mechanism or a nail mechanism or the like. Preferably, the first element comprises a base surface, a top surface, a sleeve that connects the base surface and the top surface, and a first bore perpendicular to the top surface, where the very first bore is provided with internal threads and where the second element is provided at the base surface of the first element, the connecting part of the first end element is provided with external threads and extends perpendicular to the first surface in the connected state.of the first structure, and the first part element in the connected state is screwed over the outer thread of the connecting part of the first end element. Because the connecting part is a thread over which the first end element can be screwed, the first locking mechanism is very easy to install and is also easily recyclable.25 Preferably, the head of the first end element and the connecting part of the first end element are permanently connected to each other. Alternatively, the head of the first end element may include a second bore, where the second bore is provided with internal thread, and the head of the first end element in the connected state30 is screwed over the external thread of the connecting part of the first end element BE2025 / 5086 7. By also making the head of the first end element screwable over the connecting part, it becomes very easy to attach the head of the first end element over the thread in certain designs, making the first locking mechanism very easy to install. 5Preferably, the first recess is designed as a constricting element that narrows away from the first plane of the first structure. Furthermore, the first recess is preferably provided centrally in the first plane of the first structure and is preferably designed as a conical or flattened conical recess. Alternatively, the first recess can also be designed as a hemispherical recess. Due to the constricting nature of the recess, the first element will be held in place better, making the first locking mechanism stronger. In addition, the narrowing character will also ensure that the first element is correctly positioned in the recess, allowing the connection mechanism to be placed more precisely and thereby become stronger and more universally usable. For example, in applications where large structures are connected to small structures, it is of course also important that the connection mechanism is applied very precisely to the small structure so that the connection can distribute possible loads perfectly.Preferably, the base planes and the top plane of the first element are circular planes and the base plane has a larger diameter than the top plane so that a conical element is formed, and the first recesses of the first element are designed to narrow correspondingly so that the first recess is filled by the first element in the connected state. Such a design is particularly load-bearing, because all forces on the first element are directed to a single central point in the recess. This ensures that the connection mechanism can be positioned with particular precision and that loads can be transferred very well, making the connection mechanism more universally usable.30 BE2025 / 5086 8 The first structure preferably comprises a second plane, parallel to the first plane, and a third recess that opens into the second plane of the first structure, where the third recess in the connected state accommodates the head of the first end element, where the third recess is provided for accommodating the head ofthe first end element in connected state to form the first retaining element. The first recesses and the third recess are preferably executed identically, but alternatively they can also be executed differently. Preferably, the third recess can also be executed as a constricting part, which is executed away from the second plane of the first structure. Preferably, the head of the first end element is executed identically, but alternatively they can also be executed differently, such as a simple bolt head or nut. Preferably, the head of the first end element can comprise a top surface, base surfaces and a casing that connects the top surface and the base surface, where the base surface and the top surface of the head of the first end element are circular surfaces and where the base surface has a larger diameter than the top surface so that a conical element is formed, the third recesses and the head of the first end element are executed correspondingly constricting so that the third recess in thethe connected state is filled by the head of the first end element. 20 Particularly preferred is the design in which the first end element is executed in an identical conical shape to the first part of the elements / or in which the third recess is executed identically to the first recess, since this ensures that possible connection forces are always centralized towards the connecting part, making the connection mechanism particularly strong. 25 Additionally or alternatively, the combination of one of the recesses and a head of the first end element that can be screwed onto the connecting part of the first element also leads to a very easy-to-install connection mechanism. Preferably, the connection system comprises a third structure with at least a 30 first plane, and the connection system comprises a second connection mechanism to connect the first plane of the third structure and the second plane of the first structure to each other with the map, where the first end element is part of the second connection mechanism in the connected state. Thus, the head of thethe first end element itself can again be the head of the first end element according to the invention for the second connection mechanism or a connection element according to the invention for the second connection mechanism or it can be a first or second part element according to the invention for the second connection mechanism. This makes it possible to create a connection system that connects more than two wooden structures to each other and where there is a connection between multiple connection mechanisms. Through the connection between the multiple connection mechanisms, an internal frame is formed within the wooden structures that can bear all loads and other forces, whereby the multiple connection mechanisms become even stronger through the mutual connection, while this connection will be invisible to the end user. This also allows for easily connecting more than two wooden structures to each other in a modular way. As an alternative to the above embodiment with a third recess, the first structure preferably comprises a retaining opening in the third plane, transverse to thefirst face, the head of the first end element comprises a third bore, whereby the third bore extends transversely to the third face in the connected state, and the first locking mechanism comprises a third end element, which is intended to be inserted in the connected state via the retaining opening through the third bore to form the first retaining element. Preferably, the third bore is provided with internal thread, the third end element comprises a head and a rigid elongated part, whereby the elongated part is provided with external thread, and whereby the head of the elongated part of the third end element is screwed through the third bore of the first end element to form the first retaining element. Alternatively, the third end element can be, for example, a known nail or spike or the like. BE2025 / 5086 10 This alternative design form can, for example, be used in designs where it is not possible to place the first end element via the second plane, parallel to the first plane of the first structure, and onlyIt is possible to introduce an end element via a third plane, perpendicular to the first plane of the first structure, whereby the connection mechanism according to the invention can be used in more situations and will thus be more universally usable. Preferably, the first structure further comprises a fifth recess opening into the third plane, and the third end element is placed in this fifth recess. Preferably, this fifth recess is also designed to be constricting and / or the third end element is designed as a conical element, with the known advantages described earlier. The third end element can be designed like any other end element according to the invention. 15 Preferably, the connection system comprises a third structure with at least a first plane, and the connection system comprises a second connection mechanism to connect the first plane of the third structure and the third plane of the first structure with each other by map, where the first end element is part of the second connection mechanism in the connected state, with similar advantages.as the execution form described above, whereby the second connection mechanism connects the first plane of the third structure and the second plane of the first structure to each other. Preferably, the first connection mechanism comprises a connection opening in a 25 fourth plane of the first structure, perpendicular to the first plane, and the first connection mechanism comprises a fourth end element, whereby the fourth end element is installed through the connection opening in the connected state and whereby the fourth end element is provided to connect the connection part of the first end element and a fourth structure with each other. Such a fourth 30 end element makes it possible to make further branches of the BE2025 / 5086 11 connection part via the fourth plane, perpendicular to the first plane, of the first wooden structure, thereby making it potentially possible to connect to a fourth wooden structure via this fourth end element, so that the connection system becomes even more universally usable. 5 The fourth end element further preferably comprises a nut element, whereby thisThe nut element in the connected state is screwed over the external thread of the connecting part of the first end element. This allows the fourth end element to be connected to the first end element very easily. Preferably, the nut element in the connected state is screwed over the external thread of the connecting part of the first element between the head of the first end element and the first end element, but this is not necessary. Preferably, such a fourth end element is provided in versions where the first end element is placed in the recess in the second plane and where this first end element is part of a second connection mechanism, so that it is possible to attach a wooden structure to the second plane of the first structure via the first end element and to attach a wooden structure to a fourth plane of the first structure via the third end element. This fourth end element can, preferably, in the load-bearing version, have a head that may or may not be conical. The first structure can hereby a fourth recesscomprising which opens into the fourth face of the first structure, where this fourth recess is narrowed or not, for the known advantages as described earlier. The fourth end element can be designed like any other end element of the invention. The casing of the first part element of the connecting element preferably comprises recesses and / or ribs. This allows the first part element to be easily installed with a wrench into the first structure, or onto the thread of the BE2025 / 5086 12 connecting part in the designs where the connecting part comprises a thread. The second part element of the connecting element also preferably comprises recesses and / or ribs to allow the second part element to be easily installed with a wrench into the first connecting mechanism. Any end element of the connecting system that is attached to a connecting part can also comprise such recesses and / or ribs. In preferred load-bearing forms, the second component comprises a top surface, a base surface and a mantle that connects this top surface and base surface to each other.connects, where the base plane and the top plane of the second part element are circular planes, the base plane has a larger diameter than the top plane so that a conical element is formed, and the second part element comprises a fourth bore perpendicular to the top plane, where this fourth bore is provided with internal thread. When the first part element also comprises a conical body, a bi-conical connecting element is formed. Preferably, the fourth bore and the first bore form a common bore with a common internal thread. Preferably, the first part element and the second part element are symmetrically designed with respect to each other. Preferably, the first part element is provided with a first coupling piece and the second part element of the connecting element is provided with a second coupling piece, where the first coupling piece is provided to be coupled with the second coupling piece to form the connecting element. This first and second coupling pieces can, for example, form a male / female coupling or any other.known coupling forms. This makes the connection mechanism even more modular, and allows it to be used even more universally. Preferably, the first connection mechanism comprises a flange element, where the flange element comprises a disc-shaped base body with a centric cavity and multiple bolt holes, where the flange element is positioned in the connected state between the first structure and the second structure, and where the BE2025 / 5086 13 connection element in the connected state extends through the centric cavity. Preferably, the flange element is permanently attached to the connection element. By using such a known flange element, it is possible to achieve a much stronger connection between two wooden structures, making the connection mechanism usable in even more situations. Preferably, the flange element in the connected state is partially incorporated into the first structure and partially incorporated into the second structure. In this way, the flange element can also be designed to be invisible. Furthermore, the first connection mechanism is preferably manufactured from one ormultiple polymer materials, such as, for example, acrylic fiber. Alternatively, the first connection mechanism may be made of a metal, such as, for example, cast iron, bronze, brass, aluminum, steel, cast steel, or the like. Polymer materials have the advantage of being less conductive, which means the first connection mechanism has less chance of forming a thermal bridge through the wood structures. If the connection system includes a second connection mechanism, the second connection mechanism is preferably also made of one or more polymer materials, such as, for example, acrylic fiber, or alternatively of a metal, like the first connection mechanism. The objective of the invention is also achieved by providing a structural insulation board for use in a modular construction comprising an insulation core and multiple wood structures, where the structural insulation board comprises two wood structures connected by means of a connection system according to the invention. 25The purpose of the invention is also achieved by providing a method for connecting a first and a second wooden structure by means of a connection system, where the method of connection system, according to the invention, comprises the following steps: a. the installation of the first and second element in the first and second structure respectively; BE2025 / 5086 14 b. the installation of the second locking mechanism to prevent the second element from being moved relative to the second structure; c. the installation of the first locking mechanism to prevent the first element from being moved relative to the first structure by: i. the installation of the first element in the first recess of the first structure; ii. attaching the connecting part of the first end element to the first structure;10 iii. connecting the head of the first end element and the first part element using the connecting part of the first end element; iv. attaching the first retaining element to the head ofto prevent the first end element from being moved to the first end element. Preferably, the method further comprises attaching the first part element to the second part element to form the connecting element in the connected state. This invention is now further explained on the basis of the detailed description below of some preferred forms of execution of a connection system according to this invention.

Figures 1 to 3 show a first embodiment of a connection system (1) according to the invention. This connection system 20 (1) which is suitable for connecting wooden structures with a card into a connected state, comprises a first wooden structure (2) with at least a first face (A), a second wooden structure (3) with at least a first face (B), and a first connection mechanism (11) around the first face (A) of the first structure (2) and theto connect the first plane(B)ofthesecondstructure(3) to one another. Figure 25 1 shows a connection system(1) where the first structure(2) is partially cut off so that the first plane(B)ofthesecondstructure(3) is partially visible and the first connection mechanism(11) is partially visible, while Figure 2 shows the same connection system(1) with a complete first structure(2), so that only a second plane(C)ofthefirststructure(2), parallel to the first plane(A), is visible. The first plane(A)ofthefirststructure(2) is indicated but not visible on BE2025 / 5086 17 figures 1 and 2. This first plane(A) lies against the first plane(B)ofthefirststructure(3). The first connection mechanism(11) is preferably made from one or more plastic materials, such as acrylic fiber. Alternatively, the first connection mechanism(11) can be made from a metal such as cast iron, bronze, brass, aluminium, steel, cast steel or the like. Such polymer materials are less conductive, which makes the firstconnection mechanism(11) has less chance of forming a thermal bridge through the wood structures. 10 The first connection mechanism shown (11) is shown in more detail in Figure 3, and comprises a connection element (5) with a first sub-element (51) and a second sub-element (52), which is provided to the first sub-element (51) in the connected state, where the first sub-element (51) is included in the first structure (2) in the connected state and where the second sub-element (52) is included in the second structure (3) in the connected state. The first connection mechanism (11) further comprises a first blocking mechanism (6), which prevents the first sub-element (51) in the connected state from being moved relative to the first structure (2) and a second blocking mechanism (7), which prevents the second sub-element (52) in the connected state from being moved relative to the second structure (3). The first locking mechanism(6) comprises a first end element(61), with a connecting part(611) and a head(612), where the connecting part(611) is madeis as a rigid elongated part that is incorporated in the connected state in the first structure(2)25 and connects the head(612) and the first part element(51). The first blocking mechanism(6) further comprises a first retaining element that prevents the head(612) of the first end element(61) in the connected state from being moved towards the first part element(51). The second blocking mechanism(7) comprises a second end element(71), with a connecting part30 (711) and a head(712), where the connecting part(711) is executed as a rigid BE2025 / 5086 18 elongated part that is incorporated in the connected state in the second structure(3) and connects the head(712) and the second part element(52). The The second blocking mechanism(7) further comprises a second retaining element that prevents the head(712) of the second end element(71) from being moved to the second part element(52) in the connected state.5 The first retaining element and the second retaining element, if the latter is present, can be implemented in different ways depending on theexecution. In the execution form shown in figures 1 to 3, the head (612) of the first end element (61) and the head (712) of the second end element (62) are executed as bolt heads (612-712) with a washer (61a-71a). The washer (61a) of the first end element (61) will be held in place by the second face (C) of the first structure (2), which serves as the first retaining element, while the washer (71a) of the second end element (71) will be held in place by a second face (D) of the second structure (3), which is parallel to the first face (B) of the second structure (3), with the second face (D) serving as the second retaining element. This second face (D) is indicated but not visible in figures 1-2. Further in the description, alternative retaining elements are described for alternative forms of a connection system (1) according to the invention. 20 In addition, the first structure (2) comprises a first recess (21) that opens into the first plane (A) of the first structure (2), which is difficult to see in figure 1 and betteris visible in the alternative design form of a first structure(2) shown in Figure 31. This first recess(21) opens the first part element(51) in the connected state and simultaneously prevents the first part element(51) from being moved towards the head(612) of the first end element(61), so that the first retaining elements and the first recess(21) together prevent the first part element(51) in the connected state from being moved relative to the first structure(2).30 BE2025 / 5086 19 Also the second structure(3) can in certain design forms, such as the one shown in Figures 1 to 3, be provided with a second recess(31) which opens into the first face(B) of the second structure(3), which is connected state the second part element (52) takes up and the second part element (52) prevents to move towards the head (712) of the second end element (71), so that the second retaining elements this second recess (31) together prevent the second part element (52) in connected stateto be moved relative to the second structure(3). The second recess(31) is not visible in the figures. 10 The first structure(2) and / or the second structure(3) are preferably made as wooden beams, but this is not necessary. Figures 4 to 6 show a design of a connecting element(5) according to the invention in more detail. The first part element(51) comprises a base surface(F1), a top surface(G1), a casing(H1) that connects the base surface(F1) and the top surface(G1), and a first bore(511) perpendicular to the top surface (G1), where the very first bore(511) is provided with internal thread. The second part element (52) comprises a base surface (F2), a top surface (G2), a casing (H2) that connects the base surface (F2) and the top surface (G2), and a fourth bore (521) perpendicular to the top surface (G2), where this fourth bore (521) is provided with internal thread. The base surface (F2) of the second part element (52) is provided at the base surface (F1) of the first part element (51). In the design shown in figures 4 to 6, the fourth formbore(521) and the first bore(511) a common bore with a common internal thread. The jacket(H1) of the first part element(51) and the jacket(H2) of the second part element(52) further include in this version recesses(512-522). 30 BE2025 / 5086 20 As can be seen in figures 4 to 6, the base face (F1) and the top face (G1) of the first sub-element (51) are circular planes and the base face (F1) has a larger diameter than the top face (G1) so that a conical element is formed. As can be seen in figure 1 and figure 31, the first recess (21) and the first sub-element (51) are preferably designed to be correspondingly narrowing so that the first recess (21) is filled by the first sub-element (51) in the connected state. The first element (51) and the second element (52) in these figures are symmetrical with respect to each other. The base (F2) and the top (G2) of the second element (52) are circular planes and the base (F2)10 has a larger diameter than the top (G2) so that a conical elementis formed. The second recess(31) and the second part element(52) are also preferably designed to be correspondingly narrowing so that the second recess(31) is filled by the second part element(52) in the connected state. 15 The casing(H1) of the first part element(51) and / or the second part element(52) of the connecting element(5) comprises ribs and / or recesses(512). Figures 7 and 8 show an alternative design of a connecting element (5) that can be split in the disconnected state into a first part element (51) and a second part element (52). The first part element (51) is provided with a first coupling piece (513) and the second part element (52) of the connecting element (5) is provided with a second coupling piece (523), where the first coupling piece (513) is designed to be coupled with the second coupling piece (523) to form the connecting element (5). Figures 9 and 10 show an alternative design of a connecting element (5), where the second part element (52) is not similarly designed to the first.part element (51), but instead contains a screw thread, so that this second part element (52) can be screwed into the second structure (3) when connected, as can also be seen in the connection systems of figures 24 BE2025 / 5086 21 to 27. In this design, this screw shape in combination with the second structure (3) will prevent the second part element (52) from being moved relative to the second structure (3), thereby forming the second locking mechanism (7), as can also be seen in figures 25 and 27. 5 Figures 11 and 12 show a design of a first end element (61) according to the invention, as used in the connection systems according to, for example, figures 21 and 27. The connecting part (611) of the first end element (61) is provided with external threads and extends in the connected state transversely to the first plane (A) of the first structure (2), so that the first part element (51) 10 in the connected state over the external thread of the connecting part (611)of the first end element (61) is screwed. The head (612) of the first end element (61) further comprises a third bore (613). The first structure (2) here also comprises a third face (I), transverse to the first face (A), as shown in figure 32. The first blocking mechanism (1) also includes a third end element (62), as shown in 15. can be seen in figures 13 and 14. The third bore(613) of the first end element(61) extends in the connected state transversely to the third plane(I), so that the third end element(62) in the connected state can be inserted through the retaining opening(23) through the third bore(613) to form the first retaining element. Alternatively, the first structure(2) can in certain designs further comprise a fifth recess(26) which opens into the third plane(I) of the first structure(2). This fifth recess(26) and the third end element(62) are preferably designed with corresponding narrowing in this alternative design. As can be seen in the design shown in figures 11 to 14, theThe third bore(613) is provided with internal thread, the third end element(62) comprises a head(622) and a rigid elongated part(621), where the elongated part(621) is provided with external thread, and the head(612) of the elongated part(621) of the third end element(62) is screwed through the third bore(613) of the first end element(61) to form the first retaining element. BE2025 / 5086 22 Alternatively, the third end element(62) can also be a known nail or spike or similar that is inserted through the third bore(613). Figures 15 to 17 show an alternative design of a connecting element (5) according to the invention. In this design 5, the first connecting mechanism (11) comprises a flange element (8), where the flange element (8) comprises a disc-shaped base body (81) with a centric cavity (82) and several bolt holes (83), where the flange element (8) in the connected state is placed between the first structure (2) and the second structure (3), and where the connecting element (5) in the connected state passes through the centric cavity 10(82) extends. In addition, the flange element (8) in this design is also permanently attached to the connecting element (5), but this is not necessarily the case. Figures 18 and 19 depict a first end element (61) as it is used, for example, in the connecting system (1) shown in Figure 27. Such a first end element (61) contains a head (612) which is accommodated in a third recess (22) of the first structure (2) which opens into the second plane (C) of the first structure (2), as can be seen, for example, in Figure 30. The third recess (22) is provided for accommodating the head (612) of the first end element (61) in the connected state to form the first retaining element. As can be seen in figures 18 and 19, the head (612) of the first end element (61) comprises a top surface (G3), base surface (F3) and a mantle (H3), which connect the top surface (G3) and the base surface (F3), where the base surface (F3) and the top surface (G3) of the head (612) of the first end element (61) are circular surfaces and where the base surface (F3) has a larger diameter than the top surface (G3) such thata conical element is formed, and the third recess(22) and the head(612) of the first end element(61) are made correspondingly narrowing so that the third recess(22) in the connected state is filled by the head(612)30 of the first end element(61). BE2025 / 5086 23 In certain forms of execution the connection system(1) may also comprise a third structure(10) with at least one first plane, where the connection system(1) comprises a second connection mechanism(12) to connect the first plane of the third structure(10) and the second plane(C) of the first structure(2) to each other, where the first end element(61) is part of the second connection mechanism(12) in the connected state. Such a connection system(1) can be seen, for example, in figures 28 and 29, in which a structural insulation board(9) is depicted for use in a modular construction, where this structural insulation board(9) comprises an insulation core and three wooden structures(2,3,10) connected by means of a connection system(1) according to the invention.As shown in Figure 19, the head (612) of the first end element (61) can include a fifth bore (614) across the top surface (G3), which forms part of the second connection mechanism (12). Additionally, as shown in Figure 18, the casing (H3) of the head (615) of the first end element (61) can also include ribs and / or recesses (615). Figures 22 and 23 show an execution of a connection system in which the first connection mechanism (11) contains a connection opening (24) in a fourth plane (E) of the first structure (2), perpendicular to the first plane (A) and in which the first connection mechanism (11) contains a fourth end element (63) that is inserted through the connection opening (24) in the connected state and in which the fourth end element (63) is provided to connect the connection part (611) of the first end element (61) and a fourth structure. The fourth end element (63) also contains a nut element (631), where this nut element (631) in the connected state over the external thread of theconnecting part(611)of the first end element(61) screwed. The fourth end element(63)in addition to this includes a head(632), which is cone-shaped like the connecting element(5)and head(612)of the first end element(61). The first structure(2) further includes a fourth recess(25)which opens into the fourth BE2025 / 5086 24 plane(E)and is correspondingly narrowed with the head(632)of the fourth end element(63). This fourth recess(25)and connecting opening(24) in the fourth plane(E) are also shown
