Description

Title of the invention: Modular metal structure The invention relates to the field of metal construction. It relates more particularly to a modular metal structure.

In the field of construction and for example in the construction of buildings, it is common to use a metal structure or frame.

Conventionally, the metal structure comprises several profiled elements assembled together. For large metal structures, particularly for buildings, the metal structure generally has large spans.

It therefore comprises a great diversity of elements. In particular, metal structures generally require the use of elements with different profiles and dimensions. This can cause logistical problems, on the one hand when shipping the elements to the job site and on the other hand, when assembling said elements together.

In addition, the various elements are formed in order to play a particular role in the metal structure. For example, one element is formed to constitute a beam, another element is formed to constitute a column, and so on. In other words, each element is formed for a particular purpose and each metal structure requires unique elements linked to particular configurations.

In this context, document FR 2794153 is known, the objective of which is to reduce the number and type of profiled elements used. This document discloses a metal structure in which the profiled elements all have the same shape. The profiled elements are assembled together by means of connecting plates, each connecting plate sandwiching a profiled element and an adjacent profiled element.

The use of assembly plates does not allow easy modification of the span of the structure or modification of the angle formed by two elements profiles assembled together. The structure thus formed is therefore not modular.

The object of the present invention is to solve at least one of the aforementioned drawbacks.

Thus, the invention relates to a modular metal structure comprising profiled elements, and at least one assembly accessory. Each profiled element has at each of its ends a junction piece. A profiled element is configured to be assembled to an adjacent profiled element in a configuration chosen from among

a first configuration in which a junction piece of the profiled element is fixed to a junction piece of the adjacent profiled element, the adjacent profiled and profiled elements being aligned with each other; and a second configuration in which a junction piece of each of the profile element and adjacent profile element is fixed to said assembly accessory, the profile element and adjacent profile element being inclined relative to each other.

The use of junction pieces at the ends of the profiles makes it possible to assemble the profile elements together in two configurations.

In particular, the assembly according to the first configuration allows modularity in length. It is thus possible to add the desired number of profiled elements so as to obtain an element having a particular length. This makes it possible in particular to form metal structures having large spans.

In addition, the assembly according to the second configuration allows two profile elements to be assembled together so that the two profile elements are inclined relative to each other. In other words, the two profiled elements form an angle other than 180 °.

The structure thus formed is modular as needed since the profiled elements thus formed can be assembled either according to one or the other of the first and the second configurations.

In particular, the profiled elements of the metal structure can be used in different positions (vertical, horizontal or diagonal). The assembly being carried out by fixing at the level of the junction parts in the two configurations, this makes it possible to intervene locally on this fixing for a repair or a change of profiled element but also to reuse the profiled elements subsequently for another structure. In addition, this makes it possible to reduce the number of fixing means used for assembling the profiled elements together.

According to one characteristic, the profiled elements have the same cross section and a length chosen from a set of predefined variable lengths.

It is thus possible to constitute a modular structure while using only a limited number of different profiled elements. This facilitates assembly of the structure and reduces logistical problems during assembly in the factory or on site. In particular, the risk of errors between the profiled elements during shipment to the site but also during assembly is reduced. By different profiled elements is meant profiled elements having the same cross section but different lengths.

According to one characteristic, the assembly accessory comprises fixing zones, a junction piece of each of the profiled element and adjacent profiled element being fixed to at least one fixing zone when the profiled element and adjacent profiled element are assembled according to the second configuration.

According to one characteristic, a junction part of the profiled element and a junction part of the adjacent profiled element are respectively fixed to a first fixing zone and a second fixing zone of the assembly accessory, the first and second attachment zones forming between them a predefined angle.

The predefined angle formed by the first and second fixing zones constitutes the angle between the profiled element and the adjacent profiled element. In other words, said predefined angle formed by the first and second fixing zones determines the inclination of the profile elements and the profile element adjacent to each other. According to one characteristic, each junction piece comprises a central portion, two lateral legs and a cross member, the central portion and the lateral legs forming an I-section, and the cross-member extending in a plane transverse to said I-section and to the profiled element.

The junction piece thus formed allows assembly of the profiled element at the level of the cross member but also at the level of the side legs of the junction piece, in fixing planes perpendicular to the profiled element.

According to one characteristic, the cross member of a junction part of the profiled element is fixed to the cross member of a junction part of the adjacent profiled element when the profiled element and the adjacent profiled element are assembled according to the first configuration.

According to one characteristic, a first fixing zone of the assembly accessory comprises a first plate and a second fixing plate arranged at right angles, the cross member and one of the side tabs of a junction part of the profiled element. being respectively fixed to the first and second plates of the first fixing zone when the profiled element is assembled according to the second configuration.

The first plate and the second plate form a right angle between them and are thus configured to receive the cross member and the side tab also forming a right angle.

According to one characteristic, the cross member of a junction part of the adjacent profiled element is fixed to a second fixing zone of the assembly accessory, the second fixing zone comprising a third fixing plate, and the first and second plates of the first fixing zone forming with the third fixing plate of the second fixing zone predefined angles.

In particular, the first plate of the first fixing zone forms with the third plate of the second fixing zone a predefined angle. Said predefined angle determines the inclination of the profiled element with respect to the adjacent profiled element during their assembly according to the second configuration. According to one characteristic, each profiled element comprises two C-sections having a core and two wings, said C-sections being assembled back to back at the level of the respective webs, each profiled element having an I-shaped cross section, and in which the central portion of each joint piece is joined to a part of the web of each C-section, and the side parts of each joint piece are joined to a part of the flanges of the C-sections.

The profiled element thus formed is simple to form.

According to one characteristic, the profiled elements are posts, purlins, trusses, beams, crossbow, gable, joist of said modular metal structure.

In other words, the profiled element can be used to form any part or element of the metal structure. The profiled elements are thus interchangeable, which makes the structure modular. The list of examples of elements is of course not exhaustive.

In this document, the term vertical direction is understood to mean the direction in which a column conventionally extends in a frame structure and the horizontal direction means the direction perpendicular to said vertical direction.

FIG. 1 a shows a modular metal structure 1 according to one embodiment. The structure 1 comprises profiled elements 2. The profiled elements 2 are assembled together so as to form the structure 1.

The profiled elements 2 are similar. In other words, the profile elements 2 have the same profile, that is to say that the profile elements 2 have the same cross section. The description will therefore be made for a single profiled element 2.

In the embodiment described, as clearly visible in Figures 2a, 2b, the profiled element 2 comprises two C-sections 201, or having a C-shaped cross section. Each C-section comprises a core 202 and two wings 203a, 203b called upper wing 203a and lower wing 203b. The core 202 has in the example illustrated a substantially rectangular shape. The wings 203a, 203b extend perpendicular to the web 202. The two C-sections 201 are assembled back to back.

The two cores 202 are assembled together, for example by bolting. The profiled element thus has a cross section in I. In the illustrated embodiment, the profiled element 2 comprises spacers 208 fixed to the backs of the webs 202 of the C-shaped profiles 201. The spacers 208 extend in a plane parallel to the webs 202 and perpendicular to the wings 203a, 203c. The webs 202 of the C-sections 201 are bolted at the spacers 208. The arrangement of spacers 208 makes it possible to increase the thickness of the parts of the profiled element 2 at which the C-shaped sections 201 are assembled together.

Preferably, the profiled element 2 is made of cold rolled steel. Cold rolling has interesting physical characteristics. In particular, the hardness of the steel, the tensile strength, and the resistance to deformation are more important than for standard hot-rolled steels.

The profiled element 2 here has an elongated shape. The profiled element 2 comprises two ends 200. The profiled element 2 comprises at each end 200 a junction piece 204. The profiled element 2 being in this exemplary embodiment symmetrically formed, the description is made for a single junction piece. 204 assembled at one end 200 of the C-sections 201.

The profiled element 2 has orifices. The orifices are here formed in the core 202 and at least in part of the wings 203a, 203b. In particular, the orifices are formed in the part of the wings 203a, 203b in contact with the junction piece 204.

The junction piece 204 comprises a central portion 205 also called a core, two side legs 206a, 206b also called lower leg 206b and upper leg 206a or soles, and a cross member 207 also called end plate. The side legs 206a, 206b extend perpendicular to the central portion 205. The central portion 205 and the side legs 206a, 206b form an I-section, that is to say a section having an I-cross section. central portion 205, the side legs 206a, 206b and the cross member 207 each have the shape of a rectangular flat plate. Preferably, the central portion 205, the side tabs 206a, 206b and the cross member 207 are mechanically welded together so as to form the junction piece 204.

The cross member 207 extends at the end 200 of the profiled element 2 and in a plane transverse to the central portion 205, to the side legs 206 and to the profiled element 2. The central portion 205 extends parallel to the webs 202 and between said webs 202. In particular, the central portion 205 extends along a part of the webs 202 located near the end 200 of the profiled element 2. The lateral tabs 206a, 206b extend along the side. along part of the wings 203a, 203b on either side of the profiled element 2. In particular, the upper tab 206a extends along a part of the upper flanges 203a of the C-shaped sections 201 and the lower leg 206b extends along part of the lower flanges 203b of the sections 201 in C.

Preferably, the junction pieces 204 are bolted to the C-sections 201. Thus, the central portion 205 is bolted to the webs 202 and the wings 206a, 206b are bolted to the wings 203a, 203b. As with the spacers 208, the arrangement of the central portion 205 between the webs 202 makes it possible to increase the thickness of the parts of the section member 2 at which the C sections 201 are assembled together. This also makes it possible to maintain a constant spacing between the webs 202 of the C-sections 201.

The junction piece 204 includes orifices. The orifices are here formed in the central portion 205, the two side tabs 206a, 206b and the cross member 207.

The orifices of the central portion 205 and of the lateral legs 206a, 206b, and the orifices of the webs 202 and of the wings 203a, 203b of the profiled elements

2 are formed so as to allow assembly by bolting the junction part 204 to the profiled element 2. In particular, the orifices of the central portion 205 and of the webs 202 overlap during assembly. Likewise, the orifices of the side legs 206a, 206b and the orifices of the wings 203a, 203b of the profiled elements 2 are superimposed.

The junction pieces 204 make it possible to stiffen the profiled elements 2.

The terms “lower” and “upper” are used with reference to the figures and in particular to FIGS. 2a, 2b illustrating the profiled element 2 according to one embodiment. These terms give in particular the positioning of the parts relative to each other in FIGS. 2a, 2b and are used only to simplify the understanding of the invention but should in no case be understood in a restrictive way.

Structure 1 comprises at least one assembly accessory 3, 4. In the embodiment illustrated in Figure 1a, structure 1 comprises several assembly accessories 3, 4 having different shapes. In particular, the structure 1 has corner assembly accessories 3 also called corner accessories, and ridge assembly accessories 4 also called ridge accessories 4.

The corner accessory 3 allows the assembly between two profiled elements 2 inclined relative to each other. By profiled elements 2 inclined with respect to each other is meant two non-aligned profiled elements 2.

A corner accessory 3 according to the embodiment of Figure 1a is shown in particular in detail in Figures 4a, 4b. The corner accessory 3 comprises a bottom plate 300 surrounded at least in part by peripheral plates 301 a, 301 b, 301 c forming attachment zones. Peripheral plates 301a, 301b, 301c extend perpendicular to bottom plate 300.

In the example described, the corner accessory 3 has two attachment areas. Two peripheral plates 301 a, 301 b, called first plate 301 a and second plate 301 b form a first fixing zone. The first plate 301 a and the second plate 301 b are arranged at right angles. In other words, the two peripheral plates 301 a, 301 b form a right angle between them. Another peripheral plate of the assembly accessory, called third plate 301 c, forms a second attachment zone.

Each peripheral plate of the first fixing zone forms an angle with the third plate 301 c of the second fixing zone. In particular, the first plate 301 a forms a first angle a with the third plate 301 c. For example, the first angle a is between 5 ° and 90 °. In the exemplary embodiment illustrated, the first angle a is substantially equal to 18 °. The first and second attachment zones comprise orifices. In this example, the first, second and third plates 301 a, 301 b, 301 c each comprise orifices. A ridge accessory 4 according to the embodiment of FIG. 1 a is in particular shown in detail in FIGS. 5a, 5b. The ridge assembly accessory 4 comprises four blades 401 a, 401 b, 401 c, 401 d also called first blade 401 a, second blade 401 b, third blade 401 c and fourth blade 401 d. The first blade 401 a and the second blade 401 b form between them a second angle b. For example, the second angle b is between 5 ° and 90 ° but can also be greater than 90 °. Preferably, for a two-sided structure, the second angle b is equal to twice the first angle a, ie b = 2a. The first blade 401 a and the second blade 401 b of the ridge accessory 4 are inclined with respect to each other. The third blade 401 c of the ridge accessory 4 is substantially curved. The third blade 401 c and the fourth blade 401 d connect the first and second blades 401 a, 401 b on either side. The ridge accessory 4 thus has a trapezoidal shape.

The first and second blades 401 a, 401 b form fixing zones. The first and second blades 401 a, 401 b include orifices.

During the assembly of the structure 1, the profiled elements 2 can be assembled together according to a first configuration and a second configuration. In other words, each profiled element 2 can be assembled with an adjacent profiled element 2 according to the first configuration or the second configuration.

Figure 3 shows two profiled elements 2 assembled together according to the first configuration. The two elements are also referred to as profile element 2 and adjacent profile element 2.

In the first configuration, the two profiled elements 2 are butted together, that is to say placed end to end and assembled. A junction piece 204 of the profiled element 2 is disposed against a junction piece 204 of the adjacent profiled element 2. The junction piece 204 of the profiled element 2 is then assembled to the junction piece 204 of the. adjacent profiled element 2. In particular, in the example illustrated, the cross member 207 of the junction part 204 of the profiled element 2 is disposed against the cross member 207 of the junction part 204 of the adjacent profiled element 2. The cross member 207 of the junction piece 204 of the profiled element 2 is assembled to the cross member 207 of the junction piece 204 of the adjacent profiled element 2.

The orifices of the cross member 207 of the junction piece 204 of the profiled element 2 are arranged opposite the orifices of the cross member 207 of the junction part 204 of the adjacent profiled element 2. The profiled element 2 and adjacent profiled element 2 are assembled together by means of bolts 5 inserted into the holes in the cross member 207 of the junction piece 204 of the profile element 2 and the holes in the cross member 207 of the junction piece 204 of the adjacent profile element 2 .

The assembly between the two profiled elements 2 is carried out only at the level of the junction part 204, and in particular of the cross member 207 of each of the profiled elements 2. The use of assembly means such as bolts is thus reduced. .

The first assembly configuration thus makes it possible to assemble the profiled elements 2 end to end together. The profiled elements 2 are aligned with one another. This makes it possible in particular to obtain an element formed of at least two profiled elements, said element thus having a certain length.

In a structure such as that illustrated in FIG. 1a, the first configuration makes it possible in particular to obtain a high structure and a large span. In other words, the first configuration increases the height of the columns and the length of the beams.

Furthermore, several profiled elements 2, ie of the same cross section, each having a length chosen from a set of predefined variable lengths can be used to form a metallic structure such as structure 1 of FIG. 1a. In other words, the profiled element 2 as formed allowing the assembly according to the first configuration, also makes it possible to reduce the variety of elements used for the formation of a structure. It is in fact possible, starting from a small set of variable lengths of profiled elements, to form structures having the desired heights and spans, and in particular tall structures and / or having large spans. By way of non-limiting example, it is possible to build gantries having a span of between ten meters and sixty meters, and a height of between three meters and ten meters, by means of a set composed of six predefined variable lengths of 'profiled elements 2. Said six predefined variable lengths of the profiled elements 2 may be between one meter and eleven meters. Of course, the set of predefined variable lengths can be made up of a number other than six, and can for example be between four and ten.

The length of the profile element 2 is understood to mean the dimension taken between the ends 200 of the profile element 2.

Figure 4a shows two profiled elements 2 assembled together according to the second configuration. Figure 4b is an exploded view of Figure 4a. The two profiled elements 2 are assembled together by means of the corner accessory 3.

A junction piece 204 of the profiled element 2 is assembled to a junction piece 204 of the adjacent profiled element 2 by means of the corner accessory 3. In particular, the junction piece 204 of the profiled element 2 is assembled with the first fixing zone of the profiled element 2 and the junction piece 204 of the adjacent profiled element 2 is assembled with the second fixing zone of the adjacent profiled element 2.

In the illustrated embodiment, a lateral tab and the cross member 207 of the junction piece 204 of the profiled element 2 are respectively assembled to the first and second plates 301 b of the first fixing zone of the corner accessory 3 The lower tab 206b and the cross member 207 of the junction piece 204 of the profiled element 2 are arranged against the first fixing zone of the corner accessory 3. The orifices of the lower tab 206b are arranged opposite the orifices of the first plate 301a of the first fixing zone. The holes in the cross member 207 are arranged opposite the holes in the second plate 301 b of the first fixing zone of the corner accessory 3. The profiled element 2 is assembled to the first fixing zone by means of bolts . Bolts 5 pass through the holes in the first plate 301a, the holes in the lower leg 206b and the holes in the profiled element 2 formed in the lower wing 203b facing said openings of the lower leg 206b and of the first plate 301a. Bolts 5 are inserted into the holes in the cross member 207 and the holes in the second plate 301 b.

The first fixing zone of the corner accessory 3 has a shape complementarity with the junction piece 204 In fact, in the example illustrated, the first and second plates 301 a, 301 b form a right angle, likewise that the lower leg 206b and the cross member 207 of the junction piece 204 which also form a right angle. In addition, the first plate 301 a here has substantially the same dimensions and shape as the cross member 207. The second plate 301 b here has substantially the same dimensions and shape as the lower tab 206b. The assembly of the profile element 2 to the corner accessory 3 is thus stable.

The cross member 207 of the adjacent profiled element 2 is disposed against the second fixing zone of the corner accessory 3. The orifices of the cross member 207 of the adjacent profiled element 2 are arranged opposite the orifices of the third plate. 301 c. The cross member 207 of the adjacent profiled element 2 is then assembled to the second fixing zone of the corner accessory 3. The second fixing zone, here the third plate 301 c has a shape and dimensions similar to the cross member. 207 of the adjacent profile element 2.

The adjacent profile element 2 is connected to the corner fitting 3 by means of bolts. The bolts 5 are inserted into the holes in the cross member 207 of the adjacent profile member 2 and the holes in the third plate 301c.

The profile element 2 and the adjacent profile element 2 assembled together according to the second configuration are inclined with respect to each other. The profile element 2 is inclined relative to the adjacent profile element 2 by an angle equal to the first angle a formed by the first plate 301a and the third plate 301c. In other words, the corner accessory 3 thus constituted makes it possible to assemble two profiled elements 2 by inclining them with respect to each other at the desired angle which may be equal but also different from the angle. law.

By angle of inclination of the profiled element 2 relative to the adjacent profiled element 2 is meant the angle formed by the lower flanges 203b of the profiled element 2 and adjacent profiled element 2, or the angle formed by the upper flanges 203a of the profiled element 2 and adjacent profiled element 2.

Several corner accessories 3 having different preset angles a can be formed. This allows, depending on the desired angle of inclination between two profile elements 2, to assemble said two profile elements by means of the angle accessory 3 having the first corresponding or adequate angle a.

The peripheral plates of the corner accessory 3 allow the assembly of the profile elements 2 together. On the other hand, the peripheral plates also play a role of stiffeners reinforcing the corner accessory 3. The peripheral plates serving as fixing zones thus also allow the absorption of forces from the profiled element 2 towards the adjacent profiled element. 2. In the example illustrated, the profiled element 2 is a beam and the adjacent profiled element 2 is a column. The forces are taken up from the beam to the column.

As for the first configuration, the assembly between the two profiled elements 2 is carried out only at the level of the junction pieces 204 and the fixing zones, thus reducing the number of assembly means such as bolts.

Furthermore, depending on the shape and dimensions of the profiled element 2, and in particular of the junction piece 204, the fixing zones of the corner accessory 3 can be modified so as to correspond to the piece of junction 204.

Figures 5a, 5b show two profiled elements 2 assembled together according to the second configuration by means of the ridge accessory 4.

A junction piece 204 of the profiled element 2 is assembled to the first blade 401a. In particular, the cross member 207 of the junction piece 204 of the profiled element 2 is assembled to the first blade 401 a. A junction piece 204 of the adjacent profiled element 2 is assembled to the second blade 401b. In particular, the cross member 207 of the junction piece 204 of the adjacent profiled element 2 is assembled to the second blade 401 b. The cross member 207 of the junction piece 204 of the profiled element 2 is placed against the first blade 401a. Thus, the orifices of the cross member 207 are opposite the orifices of the first blade 401a. Likewise, the cross member 207 of the junction piece 204 of the adjacent profiled element 2 is placed against the second blade 401b. Thus, the orifices of the cross member 207 are opposite the orifices of the second blade 401b. Bolts 5 are inserted in the holes of the first blade 401 a and the holes of the cross member 207 of the profiled element 2, as well as in the holes of the second blade 401 b and the holes of the cross member 207 of the element. adjacent profile 2.

The profiled element 2 and the adjacent profiled element 2 assembled together by means of the ridge accessory 4 are inclined with respect to each other. In other words, the profiled element 2 and the adjacent profiled element 2 form between them a particular angle of inclination. The term “angle of inclination” means the angle formed by the profiled element 2 and the adjacent profiled element 2, in particular the angle between the lower flanges 203b of the profiled element 2 and adjacent profiled element 2, or else the angle between the upper flanges 203a of the profiled element 2 and the adjacent profiled element 2. The angle formed by the profiled element 2 and the adjacent profiled element 2 depends on the second angle b formed by the first blade 401 a and the second blade 401 b of the ridge accessory 4. In particular, the angle of inclination and the second angle b are additional angles.

As for the corner accessory 3, several ridge accessories 4 having different predefined second angles b can be formed. This allows, depending on the desired angle of inclination between two profile elements 2, to assemble said two profile elements 2 by means of the ridge accessory 4 having the second corresponding or adequate angle b. In other words, changing the second angle b angle changes the inclination of the profile element relative to the adjacent profile element when they are assembled according to the second configuration.

The assembly is also carried out only at the level of the cross members 207, which reduces the number of fixing means used. The structure 1 comprises several feet of articulated posts 6 visible in FIG. 1a. FIG. 6 also shows in detail a post connected to a post base 6 according to the embodiment of FIG. 1a.

The post base 6 has a plate 600, an assembly plate 601 and a cross plate 602.

The plate 600 and the assembly plate 601 extend substantially parallel to each other. The transverse plate 602 extends substantially perpendicular to the plate 600 and to the backing plate 601. The plate 600, the assembly plate 601 and the transverse plate 602 form an I. The assembly plate 601 includes orifices not visible in FIG. 6. The plate 600 also comprises orifices intended to receive anchoring rods to the ground, not shown in the figures.

In the illustrated embodiment, the transverse plate 602 is on the one hand welded to the plate 600. On the other hand, the transverse plate 602 is connected to the assembly plate 601 by means of a pivot link 604 of horizontal axis.

The profiled element 2, here the post, is assembled to the post base 6 at the level of the junction part 204. In particular, the cross member 207 is assembled to the assembly plate 601. The assembly plate 601 is arranged. against the cross member 207 so that the holes in the cross member 207 and the holes in the assembly plate 601 overlap. Bolts 5 are then inserted into said holes so as to assemble the post to the post base 6.

The assembly means used to assemble the C-sections 201 to each other, the profiled elements 2 to each other according to the first configuration and the second configuration and the profiled elements 2 to the post feet 6 are bolts 5. The bolts have the the advantage of being removable, which makes the structure 1 modular and the profiled elements 2 reusable. Of course, it is possible to use any other removable assembly means.

The structure 1 can be assembled on the ground and raised using lifting means. This has the advantage of reducing operations carried out at height. In practice, the structure 1 is then guyed and then raised by means of a crane for example. In the exemplary embodiment shown, the pivot connection 604 between the post and the post base 6 allows the post to rotate relative to the post base 6 when lifting the structure 1. The assembly accessories as constituted and in particular the angle accessory 3 allow lifting of the structure in complete safety. In particular, the peripheral plates also playing a role of stiffeners prevent the dislocation of the profiled elements 2 assembled together by means of the corner accessory 3 during the lifting phase of the structure 1.

The different fixing means used in the structure 1, for example threaded rods of the bolts 5 used for the assembly of the C-sections 201, can be used for the attachment or the assembly of secondary elements or elements of trim or accessories. In other words, the profiled elements 2 are pre-equipped with fixing points for hanging or adding additional elements, trim elements, or accessories. By way of nonlimiting examples, the secondary elements can be additional elements such as purlins, stringers, joists, angles, bracing pieces. The cladding elements can be steel or wood facade and cladding elements, membrane, and the accessories can be doors, windows, signage accessories or various equipment.

Figure 7 shows examples of secondary elements attached to profile elements. In particular, Figure 7 illustrates an aluminum profile 700 attached to the profile element 2, a purlin support 701 and an anti-spill brace 702.

The present invention has been described for a particular embodiment and structure. Of course, the invention is not limited to this embodiment.

The structure 1 can also be a lattice structure.

The assembly accessories and the connecting pieces can have different shapes.

The profiled element can be formed directly from an I-section. Or, the profiled element can have a different shape. The invention thus proposes a modular structure 1 making it possible to construct buildings with a metal frame or latticework, which are entirely modular, removable and reusable.

The profiled elements forming the metal framework are interchangeable, joinable and modular. The profiled elements are made to allow two assembly configurations.

The profiled elements, available in different lengths, can be used interchangeably as columns, beams, rafters, gable frames, etc.

The profiled elements are pre-equipped with fixing points allowing additional elements to be added

The great versatility allowed by the structure of the profiled element allows an important modularity of the shapes and dimensions of the building, for example a polygonal shape, a double slope, a single slope, the inclination of the profiled elements, the formation of a surface of floors, the formation of a multi-storey structure, etc.
