Description

ASSEMBLY OF A STRUCTURE BASED ON METAL PROFILES

TECHNICAL FIELD AND OBJECT OF THE INVENTION The present invention relates to the field of light structures and more particularly relates to a wedge for the construction of a structure based on metal profiles.

The invention aims in particular to make easy the installation of facing plates, in particular plaster, for the constitution of drywall or false ceilings, or the constitution of arrangements such as shelves, for example in niche in a wall or in a partition.

STATE OF THE ART As is known, a facing plate is fixed to a metal structure, which structure is made up of sections the cross section of which is substantially in the shape of a U or a C, defined in particular in the standard NF EN 14195. For example, for the realization of a vertical partition, the structure comprises two profiles, called rails or smooth, of U-section, delimiting the partition vertically and fixed, one to the ceiling and the other to the floor. C-shaped section profiles, called uprights, are inserted between said rails and fixed to each of these rails by a self-drilling screw or a rivet or by crimping. The facing plates are fixed to these vertical uprights by self-drilling screws. The U or C-shaped section of the sections makes it possible to run between the wings of the section of said sections pipes or cables, in particular electrical, or to maintain by said wings heat or sound insulation linings. This device and this method of assembling a drywall are widely known in the prior art and are used both for the creation of partition walls and for lining partitions, when said partitions are essentially flat and more particularly vertical. However, it sometimes happens, both for architectural design needs and for renovation, that such partitions include non-planar portions, have cutaway or cornice connections with the floor or ceiling, or require the creation of niches in said partition. Under these conditions, the plasterer is required to produce the structure by cutting profiles, separating the wings from the sole, and by making junctions between the wings of the profiles at angles, by folding the cut wings. These “custom-made” cuts, folds and assemblies are difficult to achieve with the means available on site, in addition, the connections thus obtained between the profiles are weak areas from a structural point of view since they are subject to folding, to torsion or more generally to unstable deformation modes by warping of the section, said cuts and the concentration of the forces at the level of the assemblies promoting the buckling or the pouring of the profiles.

Patent application FR 3 006 391 A1 describes a wedge capable of being inserted inside the section of a C-shaped section comprising a central portion, a first wing and a second wing both extending from said central portion, perpendicular to said central portion, so as to form a channel capable of receiving said wedge. This wedge comprises a wall, called "base", from which two walls, perpendicularly extend, called "lateral" able to be inserted between the wings of the profile. The wedge also includes a plurality of bores, passing through the base wall, and a wall, termed "end", perpendicular to the side walls and to the base wall, from which protrudes a pin for connecting the shim with a bore of another shim in a sliding pivot connection.

However, this wedge of the prior art allows to join only a profile, by its base wall or its side walls, which prevents a user from achieving certain structural configurations and therefore has a drawback.

There is therefore a need for a simple, reliable and effective wedge solution making it possible to achieve certain structural configurations which are impossible to achieve with the wedges of the prior art.

GENERAL PRESENTATION OF THE INVENTION For this purpose, the invention firstly relates to a block for assembling a structure made from C-shaped sections, said block being able to be inserted into the inside the section of a C-shaped section, said section comprising a sole, from which a first wing and a second wing extend perpendicularly so as to form a channel capable of receiving said wedge, a first flange extending from said first wing in the direction of the second wing and a second flange extending from said second wing in the direction of said first wing, said shim comprising:

a wall, called "base", from which extend two walls, called "side", said side walls being able to be inserted between the wings of the profile and each comprising an upper edge connected to the base wall and a edge called "free end", opposite to said upper edge, the two free end edges of the side walls extending along a plane, preferably parallel to the base wall, called "end plane", said wall base comprising two side surfaces extending parallel to the upper edges of the side walls, at least one female fastening element, of cylindrical shape and extending from said base wall towards the end plane delimiting an orifice passing through the wall base, at least one wall, called "end", extending between the base wall and the side walls so as to close one face of the wedge, and at least one fixing element male, projecting from said end wall along a longitudinal axis and being able to link the block with a female fastening element of another block according to a sliding pivot connection, the block being remarkable in that each wall lateral includes, between its upper edge and the corresponding lateral surface (ie adjacent), a blocking portion connecting said upper edge and said lateral surface and which is adapted to receive the first edge or the second edge of the profile in order to block the wedge in rotation when the wedge is inserted in said profile.

In the wedge according to the invention, the upper edges of the side walls are adapted to support the first flange and the second flange of the profile while the locking portions advantageously make it possible to effectively block the wedge in rotation in the C-shaped profile. so as to make the structure of which it is a part both stable and solid. More precisely, by eliminating the clearance between the shim and the profile, these blocking portions make it possible both to block the shim in rotation in the profile and to at least partially block the shim in translation in the profile (by increasing the friction between wedge and profile).

According to one aspect of the invention, the base wall comprises an upper portion and a lower portion extending under the upper portion over a larger surface so as to form the two lateral surfaces.

Advantageously, the lateral surfaces of the lower portion are adapted to support the first flange and the second flange of the profile so that, depending on their dimensions, the first flange and the second flange sometimes rest on the upper edges, sometimes on the lateral surfaces.

Preferably, the blocking portion extends over a length greater than 90% of the length of the upper edge of the side wall so as to effectively block the wedge under the edges of the profile.

Preferably, the blocking portion is in the form of a shoulder, a rib or a chamfered portion which are simple means to shape while being effective in blocking the wedge in the profile.

According to one aspect of the invention, the lateral surfaces of the lower portion and / or the upper portion of the base wall are adapted to block the wedge in rotation in the profile. In particular, the wedge may comprise, between each lateral surface and the adjacent zone of the upper portion of the base wall, a second portion for blocking the wedge in rotation against the first flange and the second flange of the profile. This second blocking portion may for example be in the form of a shoulder, a rib or a chamfered portion.

Preferably, the end wall extends perpendicular to the base wall and to the side walls. It is understood here that the end wall extends along a plane which is orthogonal, two by two respectively to the plane along which the base wall extends, to the plane along which the first side wall extends and to the plane along which extends the second side wall, without however that these four planes are necessarily all together orthogonal.

According to a characteristic of the invention, the side walls extend substantially perpendicular to the base wall. By the terms "substantially perpendicular" is meant that the side walls form with the base wall an angle between 85 ° and 95 °, preferably between 88 ° and 92 °, more preferably of the order of 90 ° . In particular, the side walls can slightly retract towards the inside of the wedge in order to facilitate its insertion and its sliding in the profile.

Preferably, the wedge is in the form of a one-piece element which is both solid and easy to manufacture and handle.

Preferably, the shim is made of a plastic material, for example injection or by 3D printing, which makes it easy to manufacture.

According to one aspect of the invention, the female fixing element is of cylindrical shape in order to facilitate the fitting of the wedge with a male fixing element of another wedge while allowing a pivot connection.

In one embodiment, the shim includes a plurality of female fasteners to allow different configurations of shim assembly.

Preferably, the centers of at least two of the orifices delimited by the female fastening elements in the base wall are aligned along an axis parallel to the longitudinal axis of the male fastening element in order to allow the connection of shims of dimensions, or even of different types while aligning the side walls of said shims.

In one embodiment, the two female fastening elements are adjacent.

Advantageously, the wedge comprises at least one reinforcing wall connecting at least one of the female fastening elements to at least one of the walls of the wedge.

In one embodiment, the wedge comprises a plurality of reinforcing walls, each female fastening element being connected to each side wall by a reinforcing wall.

According to one aspect of the invention, two recesses are formed over the entire height of the lateral portions of the end wall in order to allow the complete insertion of the male fixing element of the wedge in a fixing element female of another wedge while retaining a space for sliding a profile in said two recesses.

Preferably, the length of the male fastening element is greater than the minimum distance orthogonally between the end plane of the female fastening element. This has the advantage of making it possible to receive in one of its female fastening elements, by its face designated “lower” defined between the two free ends of the side walls, a male fastening element from another wedge, in particular identical ( but not limited to). Such a connection makes it possible in particular to allow configurations of assembly of profiles which were not possible until then, for example a configuration in T with three profiles for which the wings of the three profiles are aligned, ie s' extend in two parallel planes as will be better described below with reference to the figures.

Preferably, the length of the male fastening element is less than or equal to half the difference between the thickness of the shim, increased by the depth of the recesses in the end wall, and the distance minimum orthogonally separating the end plane of the female fastening element.

In one embodiment, the male fastening element is in the form of a rod whose cross section is in the form of a cross.

According to one aspect of the invention, the male fastening element is equidistant from the two side walls, that is to say centered between the two side walls.

According to another aspect of the invention, the female fastener (s) formed in the base wall are of circular section.

Advantageously, the free ends of the side walls are capable of coming into contact with the sole of the profile.

According to one aspect of the invention, the shim comprising a second end wall, on the face opposite to the first end wall, the lower part respectively of the first end wall and the second wall d the end is substantially M-shaped so as to form two spaces on either side of the ends of the female fasteners.

The invention also relates to a profile, in particular metallic, for a structure, for example of the shelf type, said profile comprising a sole, from which a first wing and a second wing extend perpendicularly so as to form a suitable channel. receiving said shim, a first flange extending from said first wing in the direction of the second wing and a second flange extending from said second wing in the direction of said first wing, the profile comprising a shim as presented above, inserted in the section of the profile, between the first wing and the second wing, and locked in rotation by the first flange and the second flange at its locking portions.

The invention also relates to a set of shims for assembling a structure, said set comprising a first shim, as presented above, and a second shim, in particular as presented previously, comprising a male fixing element, said second wedge being connected to the first wedge by the insertion, by the underside of said first wedge, of said male fastening element into one of the female fastening elements of the first wedge.

The set of shims according to the invention allows in particular to assemble profiles so that the wings of the profiles are aligned in pairs (i.e. are in the same plane).

DETAILED DESCRIPTION OF THE INVENTION The wedge according to the invention makes it possible to assemble C-sections, in particular metallic ones, in order to produce a structure, for example of the shelf or facing wall type. To this end, the wedge according to the invention is capable of being inserted inside the section of a C-shaped section.

The example illustrated in Figure 1 shows a section 1 in C in which is inserted an example of wedge 10 according to the invention. The profile 1, also visible in FIGS. 7 to 14, comprises a sole 2 from which extend substantially perpendicularly a first wing 3 and a second wing 4 so as to form a channel 5 capable of receiving the wedge 10. In this example of profile 1 in Cé, profile 1 comprises a first flange 3A extending from the first wing 3 in the direction of the second wing 4 and a second flange 4A extending from said second wing 4 in the direction of said first wing 3.

This type of profile 1 can be used in particular for the realization of the vertical framework of a distribution partition, a counter-partition or a covering, a horizontal or creeping ceiling and is then designated "Amount". According to this method of installation, the opening of the C-shaped section of the profile 1 is oriented perpendicular to the facing plate of the partition, which facing plate is supported and is fixed to one of the wings 3, 4 of the profile. 1. This type of profile 1 can also be used for making the framework of horizontal or inclined structures, on the ceiling or in cladding, and against partitions with intermediate support and is then designated "furring". According to this installation method, the facing plates are supported and are fixed to the sole 2 of the profile 1, so that the opening of the section is oriented parallel to said facing plate. The terms “C-shaped” designate either an amount or a fur.

Referring now to Figures 2 and 3, the wedge 10 comprises a base wall 100, two side walls 110, two female fastening elements 120, a first end wall 130, a second end wall 140 and a male fastener 150.

The base wall 100 includes an upper portion 101 and a lower portion 102. The upper portion 101 is, in this nonlimiting example, of rectangular shape, of square section and extends above the lower portion 102 The upper portion 101 has an upper face 101 A, extending along a so-called “base” plane a (FIGS. 4 and 5) and in which two orifices 101B are formed (FIG. 2).

In this preferred example, the female fastener 120 located closest to the second end wall 140 advantageously allows to receive a male fastener 150 from a second wedge 10 identical so that the underside F1 or the base wall 100 of this second wedge 10 is aligned with the second end wall 140 of the first wedge 10. The female fastening element 120 located closest to the first end wall 130 advantageously allows receiving a male fastening element of a second wedge dimensioned so that the underside or the base wall of this second wedge is aligned with the second end wall 140 of the first wedge 10.

The lower portion 102 has a rectangular shape whose length and width are greater than the length of the sides of the upper portion 101 so as to form two side surfaces 102A. These two lateral surfaces 102A are adapted to support the first flange 3A and the second flange 4A of the profile 1 when the shim 10 is inserted into said profile 1.

The side walls 110 are of substantially parallelepiped shape and each extend from one of the side surfaces 102A of the base wall 100. The side walls 110 are able to be inserted between the first wing 3 and the second wing 4 of the profile 1 and each comprise an upper edge 110A extending from the lateral surfaces 102A parallel to the base plane a and a free end edge 110B, opposite to said upper edge 110A. The two free end edges 110B of the side walls 110 extend along a plane parallel to the base plane a, called the "end plane" β (Figures 4 and 5). The free end edges 110B of the side walls 110 are in particular capable of coming into contact with the interior of the sole 2 of the profile 1 in the channel 5. It will however be noted that the free end edges 110B of the side walls 110 can not be in contact with the interior of the sole 2 of the profile 1, this depending in practice on the shape and dimensions of said profile 1. Furthermore, in this preferred example, the side walls 110 extend from the base plane a at an angle between 87 ° and 89 ° in order to be able to insert and remove them easily from profile 1 while maintaining solid contact with the wings 3, 4 of profile 1, without this being limiting the scope of the present invention.

Each side wall 110 comprises, between its upper edge 11 OA and the side surface 102A adjacent to the lower portion 102, a first locking portion 110A1 connecting said upper edge 110A and said side surface 102A. The first two locking portions 110A1 of the wedge 10 are adapted to come into contact with the first flange 3A or the second flange 4A of the profile 1 in order to block the wedge 10 in rotation in the profile 1.

Preferably, each first blocking portion 110A1 can for example be in the form of a shoulder, a rib, a chamfered portion (as is the case in the figures, in particular 4 and 5) or any other suitable form. As illustrated in FIG. 6, the length c of the first blocking portions 110A1 extends substantially over the length of the upper edge 110A of the side wall 110, that is to say at least over 90% of the length from the upper edge 110A of the side wall 110.

Advantageously, the wedge 10 also comprises second blocking portions formed on the lower portion 102 of the base wall 100, in particular on the side surfaces 102A, and / or on the upper portion 101 of the base wall 100.

It will thus be noted that, depending on their dimensions, the flanges 3A, 4A can come to bear both on the upper edges 110A and on the side surfaces 102A and in blocking in rotation of the wedge 10 as well at the first blocking portions 110A1 as second blocking portions.

Note that the blocking of the wedge 10 in the profile 1 can be achieved by the first blocking portions 110A1 and / or second blocking portions and / or by the side walls 110, in particular according to the type and dimensions of the profile 1.

As illustrated in Figure 3, the female fasteners 120 are cylindrical in shape, are arranged edge to edge (ie adjacent) and extend parallel to each other from the lower portion 102 of the wall base 100 towards the end plane β and up to an end 120A by delimiting an orifice 101B passing through the base wall 100, mentioned above.

The first end wall 130 extends perpendicular to the base wall 100 and respectively 2 to 2 with each side wall 110 so as to close the front face of the wedge 10. As illustrated in Figures 2 to 4 , two recesses 130A are formed between each side wall 110 and the first end wall 130, over the entire height of the side portions 130B (FIG. 4) of the first end wall 130, in order to allow the complete insertion of the 'male fixing element 150 of the wedge 10 in a female fixing element of another wedge while retaining a space SP (Figure 12) for sliding a profile 1-1.

The second end wall 140 extends substantially perpendicular, two by two, to the base wall 100 and respectively to each of the side walls 110 so as to close the rear face of the wedge 10.

Referring to Figures 2 and 3, the male fastening element 150 extends projecting from the first end wall 130 along a longitudinal axis X and is adapted to link the wedge 10 with a female fastening element 120 of another wedge, in particular identical, in a sliding pivot connection. In this preferred example, the male fastening element 150 is in the form of a rod or a stud whose cross section is in the form of a cross.

Referring to Figure 6, the male fastening element 150 is equidistant from the two side walls 110 and the axis Y passing through the centers of the two orifices 101B formed in the base wall 100 is parallel to the axis longitudinal X along which the male fastening element 150 extends.

The wedge 10 is remarkable in that the length L of the male fastening element 150 (FIG. 2) is greater than the minimum distance d orthogonally separating the end plane β from one or the other of the female fastening elements 120 (FIGS. 4 and 5) in order to allow reception, by the lower face Fl (ie that of the end plane β) of the wedge 10, in one or the other of said female fastening elements 120 of a male fastening element 150 of another wedge, either identical, or whose length is greater than the minimum distance d.

In addition, the length L of the male fastening element 150 is less than or equal to half the difference between the thickness E (FIG. 5) of the wedge 10 increased by the depth f of the recesses 130A (FIG. 6) and the minimum distance d orthogonally separating the end plane β from the female fastening elements 120 at its end 120A:

(Æ +/- d)

L <--------- 2 In other words, the length of the female fastener 120 is preferably of the order of twice the length L of the fastener male 150 minus the minimum distance d orthogonally separating the end plane β of the female fastening element 120 at its end 120A. This makes it possible to connect two other identical shims 10 on either side of a shim 10, in the same female fastening element 120 of said shim 10 while ensuring that the male fastening elements 150 of the two other identical shims 10 are pushed in. entirely in said female fastening element 120, thus ensuring a solid connection of the three wedges 10 (FIG. 9).

As illustrated in Figure 3, the wedge 10 further comprises a front reinforcement wall 160A connecting one of the female fastening elements 120 to the first end wall 130, a rear reinforcement wall 160B connecting the other female fastening element 120 to the second end wall 140, two first lateral reinforcement walls 160C-1 each connecting respectively a female fastening element 120 to one of the side walls 110 and two second reinforcement walls 160C-2 each connecting respectively a female fastening element 120 to the other side wall 110. It will be noted that, in another embodiment of the shim 10, the shape, the arrangement and the dimensions of these reinforcement walls 160A, 160B, 160C-

1, 160C-2 as illustrated in FIG. 3, could be different or any other suitable reinforcement means could be used without limiting the scope of the present invention.

Referring to Figures 4 and 5, the lower part 130C, 140C respectively of the first end wall 130 and the second end wall 140 is substantially M-shaped so as to form two spaces E1, E2 on either side of the ends 120A of the female fastening elements 120 allowing in particular the passage of two electric cables 50 (FIG. 14) under the wedge 10 between, on the one hand, the first end wall 130 and the plane d end β, and, on the other hand, between the second end wall 140 and the end plane β. In the example of FIG. 14, two electric cables 50 have been shown, but it will be noted that the two spaces E1, E2 are adapted to receive any type of suitable object such as in particular electric cables, electric wires, pipes, conduits, tubes and that the number of these objects can be less than or more than two.

Examples of assembly of profiles 1 using one or more shims 10 will now be described, in particular with reference to Figures 7 to 13.

In the example of FIG. 7, a shim 10 as described above has been inserted at one end of a first section 1-1 in order to allow a connection, via the male fastening element 150, with a shim 20 of another type inserted between the wings 3, 4 of a second profile 1-

2. This other wedge 20 comprises a plurality of female fastening elements of the same type (in particular of the same diameter) as those of the wedge 10 in order to allow a T-shaped assembly of the two sections 1-1, 1-2. The T-shaped assembly of the sections 1-1, 1-2 is carried out by inserting the male fixing element 150 of the wedge 10 into one of the two female fixing elements of the other wedge 20 at the level from its base wall so that the wings 3, 4 of the sections 1-1, 1-2 are aligned two by two.

In the example of Figure 8, a first wedge 10-1 according to the invention was inserted at one end of a first section 1-1 and a second wedge 10-2, identical to the first wedge 10 -1, was inserted at one end of a second profile 1-2. The L-shaped assembly of the sections 11, 1-2 is carried out by connection of the male fixing element 150 of the first wedge 10-1 with one of the two female fixing elements 120 of the second wedge 10-2. The connection is advantageously made by the lower face F1 of the second wedge 10-2, that is to say through the end plane β of the second wedge 10-2 so that the first section 1-1 and the second profile 1-2 are simultaneously positioned on the edge in side view of the assembly. In other words, with this connection of the first wedge 10-1 and the second wedge 10-2, the sole 2 of the first profile 1-1 is perpendicularly opposite the sole 2 of the second profile 1-2. Such an arrangement saves space, especially in a shelving type structure or walls for facing plates. The profiles 1-1, 1-2 are assembled by inserting the male fixing element 150 of the first wedge 10-1 into one of the two female fixing elements 120 of the second wedge 10- 2 at its base wall 100 and by its lower face F1 so that the wings 3, 4 of the sections 1-1, 1-2 are aligned in pairs.

In the example of Figure 9, a first wedge 10-1 according to the invention was inserted at one end of a first section 1-1, a second wedge 10-2, identical to the first wedge 10 -1, was inserted at one end of a second profile 1-2 and a third wedge 10-3, identical to the first wedge 10-1 and to the second wedge 10-2, was inserted at one end of a third profile 1-3. The T-shaped assembly of the profiles 1-1, 1-2, 1-3 is carried out by connection of the male fixing element 150 of the first wedge 10-1 with one of the two female fixing elements 120 of the third wedge 10-3 at the base wall 100 of the third wedge 10-3, and by connection of the male fastening element 150 of the second wedge 10-2 with the same female fastening element 120 of the third wedge 10-3 by the underside F1 of the third wedge 10-3. Such an assembly of the profiles 1-1, 1-2, 1-3 advantageously makes it possible to align the wings 3, 4 of the profiles 1-1, 1-2, 1-3, in particular thanks to the use of the third wedge 10-3 according to the invention.

In the example of Figure 10, a first wedge 10-1 according to the invention was inserted at one end of a first section 1-1, a second wedge 10-2, identical to the first wedge 10 -1, was inserted at one end of a second section 1-2 and a third wedge 10-3, identical to the first wedge 10-1 and to the second wedge 10-2, was inserted at the level of the part middle of a third section 1-3 so that at least one of the female fastening elements 120 of the third wedge 10-3 are in line with an orifice 1-31 formed in the sole 2 of the third section 1 -3. The X-shaped assembly of the sections 1-1,1-2,1-3 is carried out by connection of the male fixing element 150 of the first wedge 10-1 with one of the two female fixing elements 120 of the third wedge 10-3 at the base wall 100 of the third wedge 10-3, and by connection of the male fastening element 150 of the second wedge 10-2 with the same female fastening element 120 of the third wedge 10-3 through the lower face F1 of the third wedge 10-3, through the opening 1-31. Here again, the use of shims 10-1, 10-2, 10-3 according to the invention, in particular of the second shim 10-2, makes it possible to assemble the sections 1-1, 1-2, 1-3 so that their wings 3, 4 are aligned.

In the nonlimiting example of FIG. 11, a first wedge 20 has been inserted at one end of a first section 1-1 and a second wedge 10 according to the invention has been inserted at one end of a second profile 1-2. The L-shaped assembly of the sections 1-1, 1-2 is carried out by connection of the male fastening element 150 of the second wedge 10 with one of the two female fastening elements located on the side wall of the first wedge 20 so that the base wall of the first wedge 20 is in the same plane as the base wall 100 of the second wedge 10 and that one of the wings 3 of the profile 1-2 is in the same plane as the wall free end of the first wedge 20, as illustrated in FIG. 12.

Still with reference to FIG. 12, the space SP formed at the recesses 130A of the second wedge 10 makes it possible to insert the first section 1-1 until it comes into contact with one lateral portions 130B of the first end wall 130.

In the example of Figure 13, a first wedge 10-1 according to the invention was inserted into a first section 1-1 and a second wedge 10-2, identical to the first wedge 10-1, a been inserted at one end of a second profile 1-2. The T-shaped assembly of the profiles 1-1, 1-2 is achieved by the complete insertion of the male fixing element 150 of the second wedge 10-2 with one of the two female fixing elements 120 of the first wedge 10-1 at its base wall 100 so that the wings 3, 4 of the profiles 1-1, 1-2 are aligned in pairs. Such an assembly of the profiles 1-1, 1-2 advantageously makes it possible to align the wings 3, 4 of the profiles 11, 1-2. It will be noted in particular that the space SP formed at the two recesses 130A of the second wedge 10-2 advantageously allow the first wedge 10-1 to slide in the first profile 1-1.

In the example of Figure 14, a wedge 10 according to the invention has been inserted in a profile 1. Two cables 50 extend in the spaces E1, E2 formed respectively between the lower part 130C, 140C of the first end portion 130 and of the second end portion 140 and the sole 2 of the profile 1. In other words, the specific shape of the lower face Fl of the wedge 10 allows the passage of the two cables 50 between the wedge 10 and sole 2 of the profile.

The wedge 10 according to the invention therefore allows for specific assemblies of profiles 1, in particular so that the narrowest section of all the profiles 1 is oriented on the same side, thus making the structure compact. and harmonious.

The present invention is not limited to the figures described above. In particular, other shapes and dimensions of shims can be envisaged.
