Description

CONNECTION JOINTS FOR BUILDING
The present invention relates to a connection joint that may be used in the building industry to connect perimeter and/or interior non-load-bearing walls of a building.
The use of connection joints for the assembly or construction of non-load- bearing walls in the building industry has long been known.
Such joints comprise reciprocally connectible metal elements configured to define uprights in which to retain the respective ends of wooden boards (matchboards or slats) or the like which in turn define the individual non-load- bearing walls.
The appended Figure 1 shows, by way of example, an embodiment of a connection joint of the known type which comprises two metal elements with an elongate shape, reciprocally connectible so as to define a clamp element in which end portions of laminated wood elements, such as matchboards or slats, may be accommodated and retained in place.
In particular, a first metal element Ml is in the form of a corner bracket to which a second metal element M2, in the form of a perforated, elongate plate, may be connected by bolting. When the second metal element M2 is tightened relative to the first metal element Ml it forms a clamp in which wooden boards placed one on top of the other can be retained so as to define a non-load-bearing wall P.
A lower frame M3, in which flooring M4 is positioned, and an upper frame along which a covering is installed, are constrained to the first metal element Ml.
A connection joint of this kind enables the building of robust wooden constructions. However, during its installation, the action of tightening between the first metal element Ml and the second metal element M2 entails that the latter, while the bolt system is being screwed tight, is pressed against the ends of the wooden boards interposed between the two metal elements until it contacts, with its edges, the ends themselves, partially penetrating them.
Practically, the connection joint entails a localised concentration of the clamping action along the ends of the boards engaged in the joint.
Document FR 2042252A5 describes a pre-fabricated modular system which, among the various components, comprises a connection joint for joining two non-load-bearing walls, aligned or orthogonal to each other. This joint has a complex configuration as it provides for the use of elements that act as a clamp and a "U-shaped" profiled barthat acts as a base element in which the other clamp elements are operatively connected.
The object of the present invention is to enable the composition and connection of modular construction elements which can be reciprocally disassembled and reassembled to achieve a composition of a modular building structure in a simple, efficient, and economical manner.
Another object of the present invention is to reciprocally connect non- load-bearing walls of a modular type in order to perimetrically delimit and/or internally divide a room.
A further object of the present invention is to simplify the reciprocal connection of pre-fabricated elements - non-load-bearing wall sections - by using an extremely reduced number of tools.
The specific subject matter of the invention relates to a connection joint configured to reciprocally connect non-load-bearing wall elements, wherein the connection joint comprises at least a first elongate element, at least a second elongate element which is movable relative to the at least a first elongate element, connection members of a removable and adjustable type for reciprocally connecting the at least a first elongate element and the at least a second elongate element by tightening them, wherein the at least a first elongate element and the at least a second elongate element, when they are connected, reciprocally define an upright and delimit between them two or more housing seats of an adjustable width which extend along a direction of extension, wherein each of the housing seats is accessible through a respective opening delimited between a wall of the at least a first elongate element and a respective wall of the at least a second elongate element, wherein the wall and the respective wall are parallel to each other.
According to another aspect of the invention, each of the at least a first elongate element and the at least a second elongate element can be configured as a sheet shaped by means of a double bending so as to have three consecutive sides.
According to a further aspect of the invention, the at least a first elongate element can have a central side from whose opposite ends the two outer sides extend symmetrically and the at least a second elongate element has a central portion from whose opposite sides respective outer portions project, wherein the outer portions extend from the central portion by a distance that is smaller than the distance by which the outer sides project from the central side.
According to an additional aspect of the invention, each of the outer sides can delimit with the central side a same bending angle that corresponds to a bending angle delimited between each of the outer portions relative to the central portion.
According to another aspect of the invention, the connection joint can comprise two first elongate elements and two second elongate elements, wherein the connection members comprise pins that project from one of the two second elongate elements and engage respective holes delimited in the other of the two second elongate elements.
According to a further aspect of the invention, the connection joint can comprise a base element from which the first elongate elements project in a position opposite each other and wherein the two second elongate elements are opposite each other and positioned interposed between the two first elongate elements.
According to an additional aspect of the invention, the connection joint can comprise a first elongate element in the form of a plate element and a second elongate element in the form of a plate element, wherein the first elongate element has a greater width than the second elongate element.
According to another aspect of the invention, the connection members can comprise pins that project orthogonally from the first elongate element and engage respective holes delimited along the second elongate element and nuts for tightening the pins in place, wherein the first elongate element and the second elongate element, when they are connected by means of the connection members, are aligned parallel to each other and delimit two housing seats opposite each other.
According to a further aspect of the invention, the first elongate element can have, in a bottom portion thereof, an appendage that projects orthogonally and acts as a base for connecting the first elongate element to a support, wherein the appendage delimits at least one through opening for connecting the first elongate element to a support or abutment.
According to an additional aspect of the invention, the connection joint can be configured as a "T" and comprise a first elongate element and two second elongate elements, wherein the first elongate element is configured as a plate elongated along the direction of extension and each of the two second elongate elements is in the form of a sheet shaped by bending so as to obtain two consecutive sides orthogonal to each other.
According to another aspect of the invention, each of the second elongate elements can have a first side and a second side, wherein the first side of each of the second elongate elements is configured to face the first elongate element when the connection joint is assembled, and the second side of each of the second elongate elements is configured to face a second side of the other of the second elongate elements.
According to a further aspect of the invention, the connection members can comprise first threaded connections for reciprocally connecting each of the second elongate elements to the first elongate element and second threaded connections for reciprocally connecting between the two second elongate elements.
According to an additional aspect of the invention, the first threaded connections can comprise two rows of pins arranged spaced apart from and parallel to each other along the first elongate element, wherein each of the pins is configured to engage a respective hole among a plurality of holes delimited along the first side of each of the second elongate elements and be retained therein by means of a respective nut among nuts comprised in the first threaded connections.
According to another aspect of the invention, the second threaded connections can comprise a plurality of respective pins configured to engage in a pass-through manner respective second holes among a plurality of second holes which are delimited to pass through each of the two second elongate elements, wherein the second holes are delimited along the two second elongate elements aligned with each other.
The advantages offered by the connection joint according to the invention are evident.
In fact, the connection joint according to the invention has a limited number of components which are reciprocally connectible by means of bolted connections in order to produce a clamp element for retaining respective end portions of non-load-bearing wall elements, made for example with wooden boards, slats or panels made of wood or plastic or a composite material, in a stable and secure manner.
The connection joint, in particular, comprises portions for clamping respective ends of construction elements to be reciprocally connected, wherein the clamping portions are configured parallel in order to distribute the clamping action in an optimal manner, thereby avoiding the concentration of stresses that afflicts solutions of a traditional type.
The connection joint according to the invention comprises at least one fixed clamping element and at least one movable clamping element which are reciprocally connectible by means of a bolted connection. In order to assemble the connection joint it is sufficient to use a wrench, preferably a torque wrench, in the context, therefore, of a solution of practical execution and installation.
The present invention will now be described by way of illustration and not limitation according to the preferred embodiments thereof, with particular reference to the Figures in the appended drawings, wherein:

Figure 11 shows a top view of the connection joint as per Figure 10.
With reference to the appended Figures 2-4, a first embodiment of a connection joint is denoted in its entirety by 1.
The connection joint 1 is configured as a vertical upright which delimits at least two housing seats opposite each other, in which to position respective end portions of panels, slats or more in general non-load-bearing wall elements or non- load-bearing walls P to be reciprocally connected. The non-load-bearing walls P will not be described in detail as they do not form the specific subject matter of the invention.
The housing seats are oriented orthogonally or substantially orthogonally to each other.
As will be better described below, the width of the housing seats is adjustable according to the thickness of the end portions to be connected by means of the connection joint 1.
The connection joint 1 comprises a first elongate element 2, a second elongate element 3, and connection members 4, of a removable type, for reciprocally joining to each other the first elongate element 2 and the second elongate element 3.
In greater detail, the first elongate element 2 extends along a direction of extension 5 which, during use, corresponds to a vertical or normal direction relative to a support plane.
The first elongate element 2 is in the form of a sheet shaped by a double bending so as to obtain three consecutive sides (see for example Figure 4).
In greater detail, the first elongate element 2 has a central side 6 at whose opposite ends two outer sides 7 extend symmetrically.
By way of non-limiting example, each of the central side 6 and/or the outer sides 7 has a width or extent of about 50, 60 mm. It is to be understood that according to an alternative embodiment not illustrated in the appended Figures, the central side 6 and/or the outer sides 7 can have different sizes, larger or smaller than the ones stated above.
The first elongate element 2 has a connection portion in a bottom portion of the first elongate element 2 itself.
The connection portion is preferably in the form of an appendage 8 that projects orthogonally from the first elongate element 2 and acts as an abutment for the installation of the first elongate element 2 in an orthogonal position relative to a support against which it is positioned (see Figures 3 and 4). The appendage 8 delimits at least one through opening 9 that is engageable, for example by means of a pin or a threaded bar that projects from a horizontal frame to which it is intended to connect the first elongate element 2.
According to one embodiment, the connection joint 1 comprises a base element 10 connectable to a bottom end of the first elongate element 2 through the appendage 8.
The base element 10 has, in a plan view, a larger extent compared to the appendage 9 and provides a rest base for supporting the first elongate element 2.
According to an alternative embodiment of the connection joint 1, not illustrated in the appended Figures, the base element 10 forms a single body with the first elongate element 2, optionally in place of the appendage 8, as it performs an analogous function.
The second elongate element 3, similarly to what was described in relation to the first elongate element 2, is in the form of a sheet shaped by a double bending so as to obtain three consecutive sides.
The second elongate element 3 has a central portion 11 from whose sides respective opposite outer portions 12 project symmetrically.
The central portion 11 delimits a plurality of holes 13 engageable by the connection members 4 so as to reciprocally connect the first elongate element 2 and the second elongate element 3 (see Figure 2, in which the holes 13 are indicated by a broken line).
According to a preferred embodiment, the connection members 4 comprise a plurality of threaded pins 14 (see for example Figure 3) which project orthogonally from the central side 6, in the area delimited between the outer sides 7, and each engages a respective hole among the holes 13 and respective nuts 15 for adjusting the tightening position of the second elongate element 3 relative to the first element 2.
The holes 13 and the pins 14 are reciprocally aligned along the direction of extension 5.
The distance at which the individual pins 14 are positioned along the central side 6 of the first elongate element 2, and more precisely along the direction of extension 5, corresponds to the distance at which the holes 13 are delimited along the central portion 11 of the second elongate element 3.
According to an alternative embodiment, not illustrated in the appended Figures, the pins 14 can be removably connected to the central side 6 of the first elongate element 2. By way of example, along the central side 6 of the first elongate element 2, nuts 16 can be constrained, for example by welding, the nuts acting as a seat for the installation of a respective pin among the pins 14, which can be screwed thereinto.
It is noted that each of the outer sides 7 delimits with the central side 6 a same bending angle, which corresponds to a bending angle delimited between each of the outer portions 12 relative to the central portion 11.
Therefore, when the connection joint 1 is assembled, i.e. the second elongate element 3 is connected to the first elongate element 2, the outer sides 7 and the outer portions 12 are aligned with each other in a parallel manner or a substantially parallel manner.
Similarly, the central side 6 of the first elongate element 2 and the central portion 11 of the second elongate element 3 are likewise aligned with each other in a parallel manner or a substantially parallel manner (see Figure 3).
The connection joint 1 has a space delimited between the first elongate element 2 and the second elongate element 3 which is accessible from opposite sides through a first entry and a second entry opposite each other and delimited between the outer sides 7 and the outer central portions 12.
The first elongate element 2 and the second elongate element 3, when they are reciprocally connected, define an upright element or upright and delimit between them two housing seats that extend along the direction of extension 5. Each housing seat is accessible through a respective opening delimited between a wall of the first elongate element 2 and a respective wall of the second elongate element 3, wherein the wall of the first elongate element 2 and the respective wall of the second elongate element 3 which face each other are mutually parallel. Preferably, the outer portions 12 extend from the central portion 11 for a shorter distance than the distance by which the outer sides 7 project from the central side 6.
In other words, the outer sides 7 project externally to the outer portions 12, thus providing a lead-in and a guide to promote the insertion of non-load- bearing wall elements P into the connection joint 1 and, more precisely, into respective housing seats delimited between the first elongate element 2 and the second elongate element 3.
The specific conformation of the first elongate element 2 and the second elongate element 3 allows respective end portions of non-load-bearing wall elements P to be clamped between them without impacting the surface thereof in any way. In this manner, it is possible to securely retain in the connection joint 1 non-load-bearing wall elements P constructed with panels or strips substantially of any kind and made of any material, such as, for example wood panels, wood slats or sound-absorbing or heat-insulating panels without damaging them.
A further embodiment of the connection joint according to the invention is indicated in the appended Figures 5-7 and denoted by 100.
The connection joint 100 differs from the previous embodiment as regards the number and relative positioning of the non-load-bearing wall elements. In particular, the connection joint 100 is configured to securely retain in place four non-load-bearing wall elements P in a position orthogonal to each other, i.e. in cross-like fashion.
In the description that follows, in order to indicate components corresponding to the ones described in relation to the previous embodiment the same numbers increased by one hundred will be used.
The connection joint 100 comprises two first elongate elements 102 and two second elongate elements 103 reciprocally connectible by means of connection members 104 so as to delimit four housing seats arranged orthogonally to one other, each accessible through a respective opening aligned along a direction of extension 105, along which the connection joint 100 extends. The connection joint 100 comprises a base element 110 from which the two first elongate elements 102 project orthogonally.
The two first elongate elements 102 are constrained to the base element 110.
Each of the two first elongate elements 102 is in the form of a sheet shaped by means of a double bending so as to obtain three consecutive sides and has a central side 106 at whose ends two outer sides 107 extend.
The two first elongate elements 102 are positioned opposite each other along the base element 110, with the respective outer sides 107 diverging. In other words, each of the first elongate elements 102 delimits a concavity opposite that of the other of the first elongate elements 102.
According to an alternative embodiment, not illustrated in detail in the appended Figures, the two first elongate elements 102 are connected to the base element by means of a bolted coupling. According to this version, by way of nonlimiting example, each of the two first elongate elements 102 comprises an appendage, configured for example as a tab or the like, which projects orthogonally in a bottom portion of each of the two first elongate elements 102, starting from the central side 106, in a position interposed between the two outer sides 107.
The tab delimits at least one through opening engageable by means of a pin or a bolt for the connection between the tab itself and the base element 110.
The two second elongate elements 103 are likewise formed as a sheet shaped by means of a double bending so as to obtain three consecutive sides.
Each of the second elongate elements 103 has a central portion 111 at whose ends two outer portions 112 extend.
The two second elongate elements 103 have the same dimensions or substantially the same dimensions.
It is noted that the angle delimited between the two outer sides 107 of each of the first elongate elements 102 corresponds to the angle delimited between the two outer portions 12 of each of the two second elongate elements 103.
The two second elongate elements 103 are positioned opposite each other, similarly to the opposite positioning of the first elongate elements 102.
The connection joint 100 differs from the previous embodiment as regards the manner in which the connection members 104 bring about a connection between the two second elongate elements 103 and, consequently, between the two first elongate elements 102.
The connection members 104 comprise pins 114 that project from one of the two second elongate elements 103 and engage respective holes 113 delimited in the other between the two second elongate elements 103.
The pins 114, similarly to what was described in relation to the previous embodiment, extend along the direction of extension 105 aligned with each other and can project from one of the two second elongate elements 103 to which they are constrained or removably connectible.
With reference to the embodiment illustrated in the appended Figure 6, one of the two second elongate elements 103 has nuts 116 in the central portion 111 which act as a support in which to engage respective pins 114, which will then in turn be engaged in the other of the second elongate elements 103.
In orderto connect the non-load-bearingwall elements P to the connection joint 100 it is sufficient to reciprocally connect the two second elongate elements 103, positioning them interposed between the two first elongate elements 102 so as to delimit four housing seats within the space delimited between the first elongate elements 102 and the second elongate elements 103.
Each of the four seats is accessible through a respective opening elongated along the direction of extension 105.
In order to connect the four non-load-bearing walls P by means of the connection joint 100, the ends of each of the non-load-bearing walls P are positioned inside a respective housing seat and clamped in place by means of the connection members 104. Practically, tightening the nuts 115 along respective pins 114 brings the two second elongate elements 103 closer to each other and likewise to the two first elongate elements 102, thereby clamping end portions of the non-load-bearing walls P inside the connection joint 100.
The clamping action exerted by the connection joint 100 along the end portions of the non-load-bearing walls P is balanced as a result of the configuration of the connection joint 100 itself. Similarly to what was described in relation to the previous embodiment, in fact, the outer sides 107 of the first elongate elements
102 and the corresponding outer portions 112 of the second elongate elements
103 are facing parallel to each other, thus delimiting respective housing seats, configured as linear along the direction of extension 105, in which to accommodate end portions of the non-load-bearing walls P.
The base element 110 has connection holes 117 for connecting the connection joint 100 to a support, for example by means of a bolted connection not illustrated in detail in the appended Figures.
As mentioned, according to one variant of the invention not illustrated in the appended Figures, each of the two first elongate elements 102 has a respective connection tab that projects in a base portion, starting from the central side 106, and delimits at least one through hole for connecting to the base element. The through hole is preferably aligned with a corresponding connection hole 117 delimited along the base element 110 to enable the connection of the connection tab and, therefore, of the respective elongate element between the first elongate elements 102 from which the tab itself projects.
With reference to the appended Figures 8 and 9, a further embodiment of the connection joint according to the invention is shown and denoted by 200.
In the description that follows, in order to indicate the same components of the connection joint 1, the same numbers increased by two hundred will be used.
The connection joint 200 differs from both of the previous embodiments in relation to the configuration of the first elongate element 202 and the second elongate element 203.
The first elongate element 202, in fact, is in the form of a flat plate element, without outer sides inclined relative to a central side.
The second elongate element 203 is likewise in the form of a flat plate element, without outer portions inclined relative to a central portion.
The connection joint 200 comprises connection members 204 configured analogously to the connection members described in relation to the previous embodiments.
The connection members 204, in fact, comprise pins 214 connected to the first elongate element 202, aligned with each other along a direction of extension 205 of the first elongate element 202.
The pins 214 project orthogonally from the first elongate element 202 and engage respective holes 213 delimited along the second elongate element 203.
The connection members 204 comprise nuts 215 engageable along the pins 214 in order to reciprocally connect the first elongate element 202 and the second elongate element 203, by tightening them together.
The first elongate element 202 and the second elongate element 203 each have lateral portions that project from the opposite sides of a central portion in which the connection members 204 are positioned, so as to delimit respective spaces or seats to accommodate the ends of non-load-bearing wall elements P to be reciprocally connected by means of the connection joint 200.
The first elongate element 202 and the second elongate element 203, when are connected reciprocally, are aligned parallel to each otherto enable even, distributed clamping along the direction of extension 205 of respective end portions of the non-load-bearing wall elements P connected by means of the connection joint 200.
The first elongate element 202 has a width or breadth, i.e. a dimension along a direction perpendicular to the direction of extension 205, which is greater than that of the second elongate element 203. In this manner, the connection joint, 200 when assembled, has opposite portions of the first elongate element 202 that project externally relative to those of the second elongate element 203, acting as a guide to favour the insertion of the non-load-bearing wall elements P in the respective housing seats.
By way of non-limiting example, the first elongate element 202 has a width of 120mm whilst the second elongate element 203 has a width of 100mm. It is understood that alternative embodiments of the connection joint 200 are possible in which the first elongate element 202 and the second elongate element 203 each have a respective dimension in width that is different from the previously indicated one, that is, greater or less than the values described, according to the thickness of the panels to be assembled.
The first elongate element 202 has, in a bottom portion thereof, an appendage 208 that projects orthogonally. The appendage 208 acts as a base element for connecting the first elongate element 202 to a support or an abutment. The appendage 208 delimits at least one through opening 209 for enabling the connection of the first elongate element 202 to a support or an abutment by means of a bolted connection, not illustrated in detail in the appended Figures.
According to a preferred embodiment, the appendage 208 delimits two through openings 209 (see Figure 8).
With reference to the appended Figures 10 and 11, they show a further embodiment of the connection joint according to the invention, denoted in its entirety by 300.
Hereinafter, in order to indicate the same components of the connection joint 1 the same numbers increased by three hundred will be used.
The connection joint 300 differs from the previous embodiments as regards its conformation.
In fact, the connection joint 300 is configured so as to define a "T" connection between three non-load-bearing wall elements P, two of which are aligned parallel to each other whilst a third non-load-bearing wall element P is orthogonal to them.
The connection joint 300 comprises a first elongate element 302 and two elongate elements 303 which can be reciprocally removably connected by means of connection members 304.
In particular, the first elongate element 302 is configured as a plate elongated along a direction of extension 305, whilst the two second elongate elements 303 are in the form of a sheet shaped by a single bending so as to obtain two consecutive sides orthogonal to each other.
Each of the second elongate elements 303 has a first side 317 and a second side 318, wherein the first side 317 of each of the second elongate elements 303 is configured to be facing the first elongate element 302, when the connection joint 300 is assembled, whilst the second side 318 of each of the second elongate elements 303 is configured to be facing the second side 318 of the other of the second elongate elements 303.
The connection members 304 comprise first threaded connections 319 for reciprocally connecting each of the second elongate elements 303 to the first elongate element 302 and second threaded connections 320 for reciprocally connecting the two second elongate elements 303.
In greater detail, the first threaded connections 319 comprise two rows of pins 314 arranged spaced apart from and parallel to each other along the first elongate element 302, wherein each of the pins 314 is configured to engage a respective hole among a plurality of holes 313 delimited along the first side 317 of each of the second elongate elements 303.
It is noted that, according to a preferred embodiment, the holes 313 are in the form of slots aligned along a direction orthogonal to the direction of extension 305.
The holes 313 are shaped so as to enable a correct clamping distance for the non-load-bearing wall element P, which is connected perpendicularly to the first elongate element 302, as are the two second elongate elements 303, between which the non-load-bearing wall element P is positioned and retained and which are in turn connectible to the first elongate element 302.
By way of example, a procedure of assembling the connection joint 300 comprises reciprocally connecting the two second elongate elements 303 by means of the second threaded connections 320, positioning a non-load-bearing wall element P in a position interposed between the two second elongate elements 303, clamping the non-load-bearing wall element P in place by acting on the second threaded connections 320, tightening them, and then connecting the two first elongate elements 303 to the first elongate element 302 by means of the first threaded connections 319.
The holes 313 delimited along each of the two second elongate elements 303 enable a stable connection between the two second elongate elements 303 themselves and the first elongate element 302 for various thicknesses of the non- load-bearing wall element P, i.e. also given a variation in the relative distance between the two second elongate elements 303 determined by the thickness of the non-load-bearing wall element P interposed between them.
The second threaded connections 320 comprise a plurality of respective pins 321 configured to engage in a pass-through manner respective second holes among a plurality of second holes 322 which are delimited to pass through each of the two second elongate elements 303. In this regard, it is noted that the second holes 322 are delimited along the two second elongate elements 303 so as to be aligned with each other. In other words, as the two second elongate elements 303 are reciprocally aligned, the second holes 322 are aligned with one another.
The first threaded connections 319 comprise nuts 315 for tightening the first side 317 of each of the second elongate elements 303 relative to the first elongate element 302.
The second threaded connections 320 comprise respective nuts 323 for reciprocally connecting the two second elongate elements 303 and tightening the second sides 318 against each other.
The connection joint 300 delimits three housing seats in which to accommodate and retain respective non-load-bearing wall elements P, wherein two of the three housing seats are aligned parallel to each other and a third housing seat is aligned orthogonally with the remaining two seats. The three housing seats are delimited in a space which is in turn delimited between the first elongate element 302 and the two second elongate elements 303 and between the first threaded connections 319 and the second threaded connections 320.
In greater detail, it is noted that each of the first threaded connections 319 and the second threaded connection 320 defines an abutment against which a portion of ends of the non-load-bearing wall elements P to be retained in the connection joint 300 is abuttingly placed.
Similarly to what was described in relation to the previous embodiments, the connection joint 300 also enables the clamping action to be evenly distributed between the first elongate element 302 and the two second elongate elements 303, as in the case of the clamping action brought about between the two second elongate elements 303 themselves.
By way of non-limiting example, the first elongate element 302 has a dimension in width, i.e. a dimension along a direction transversal to the direction of extension 305, of about 120 mm, though it is understood that alternative embodiments are possible wherein the first elongate element 302 has a width of larger or smaller dimensions than the previously described value.
The connection joint 1, 100, 200, 300 according to the invention is capable of achieving the pre-established objectives by assuring a secure clamping of non- load-bearing wall elements P, also of varying thickness, in the specific housing seats delimited between at least a first elongate element 2, 102, 202, 302 and at least a second elongate element 3, 103, 203, 303.
The connection joint 1, 100, 200, 300 is capable of distributing the clamping force evenly along the direction of extension 5, 105, 205, 305 without damaging the portion of the non-load-bearing wall elements P retained therewithin, thus overcoming one of the drawbacks of the solutions of a traditional type.
The different configurations of the connection joint 1, 100, 200, 300 make it possible to achieve respective configurations of connection between the non- load-bearing walls P, such as 90° connections between two or three or even four non-load-bearing walls P, as well as 180° connections between two non-load- bearing walls P. The connection joint 1, 100, 200, 300 according to the invention can be used both with wood non-load-bearing wall elements, such as, for example, matchboards, slats and panels and substantially ones made of any type of building material for the construction of sheds, structures suitable for forming movable walls and spaces between walls, storage shelters, interior rooms in buildings, etc.
The connection joint 1, 100, 200, 300 according to the invention has high flexibility and modularity in its application and ensures the construction of walls or structures of a temporary or permanent type at a moderate cost, as it requires an extremely limited use of tools or equipment for their installation. It can in fact be assembled simply using wrenches (preferably torque wrenches) to tighten the connection members 4, 104, 204, 304.
In the foregoing, the preferred embodiments of the present invention have been described and variants have been suggested, but it is to be understood that the persons skilled in the art may introduce modifications and changes without going beyond the scope of protection as defined in the appended claims.
