Description

PROFILE SYSTEM FOR A BUILDING STRUCTURE AND INSTALLATION PROCEDURE DESCRIPTION Field of the invention The present invention falls within the construction sector and more specifically in construction profiles for the construction of suspended ceiling structures, walls and façade enclosures. State of the art The production of building structures, whether horizontal (such as suspended ceilings) or vertical (such as walls or façade enclosures) using plasterboard or, in general, any other type of flat building products, is achieved using an auxiliary structure which, in many cases, is a structure made of metal profiles, generally rolled steel profiles. According to applicable construction regulations, the deformation of these auxiliary structures when the partitions, ceilings, and enclosures are installed and in use is limited. The functional loads to which these components are subjected are their own weight, the loads of the partition, ceiling, or façade enclosure, and the environmental stresses they may withstand, such as wind forces, etc. Therefore, in their usable state and subjected to the maximum anticipated stresses, the components used in structures must not exceed the maximum deformation established, depending on the type of roof, partition, or façade enclosure and its intended use. Additionally, these elements, after being subjected to these stresses, must return to their original, deformation-free state. When the functional loads supported by these components are large or when the distance between the fixing points of said components to the structural elements of the building is large, mixed auxiliary structures are usually used. In general, a mixed auxiliary structure requires: 2195931 of 34 - A first structure: the function of this structure, called the primary structure, is to support and transmit the loads to the fixing points of the auxiliary structure to the structural elements of the building. - A second structure. This second structure, called the secondary structure, is the one to which the plasterboards are attached and, at their attachment points to the primary structure, distributes the loads carried by said plasterboards or flat construction products. The primary and secondary structures are typically each made up of parallel profiles. The primary profiles are separated from each other by a certain distance, called primary modulation (L). Similarly, the secondary profiles are separated by a certain distance, called secondary modulation (S). The profiles that make up the primary structure are usually perpendicular to the profiles that make up the secondary structure. Therefore, the efficiency of a building structure can be measured by the following parameters: - Flatness of the flat element once said element is subjected to normal working load. - Fewer attachment points (hanging points) to the building's structural elements. This parameter is measured in the number of attachment points per square meter of roof. In turn, the lowest number of fixing points is determined by: - The greatest separation distance between the attachment points on the structure in the direction of the primary structure. This parameter is measured as the distance in meters between attachment points, according to the direction of the primary profiles. - Greater separation between the primary structure profiles (greater primary modulation). This parameter is measured as the distance in meters between primary profiles, along the perpendicular direction. The profiles of the primary structure are usually at different levels than the profiles of the secondary structure, so that the profiles of one of the structures do not interfere with the profiles of the other. However, on other occasions, such as in the structures of 2195931 of 34 plasterboard ph45, interference and weakening of one of the structures does occur, generating a system with a high cost and lower efficiency. Generally, when using composite structures, flat building products are installed using screws, fixing these only to the profiles of the secondary structure. The rigid connection of the metal profile that forms the secondary structure with the flat product that forms part of the partition, ceiling or façade enclosure allows both to collaborate mechanically and increases the rigidity of the assembly, allowing for greater useful spans between the support points of the profiles for the same maximum deformation of the partition, ceiling or enclosure. The connection between primary and secondary profiles is usually made using connecting pieces between profiles. When this connection is made with connecting pieces, a large number of these pieces are required. Therefore, the use of this large number of pieces results in increased time and difficulty in installing the building structure, which translates into higher installation costs. The connection of secondary profiles to the primary profiles is usually intended to prevent them from separating in the direction perpendicular to the plane of attachment of the flat element. It generally does not prevent the secondary profiles from shifting relative to the primary profiles in any of the other dimensions of the space once attached. The process of adjusting the separation between profiles is carried out, in this case, profile by profile, during the installation and attachment of the flat product. In some cases, the primary structure profiles have a perforated element that facilitates the attachment of the secondary profiles to the primary structure profiles. These perforations also allow the spacing between auxiliary profiles to be predefined (secondary modulation - S). When perforations are made in areas of the primary profile far from its neutral grain, or even affecting one of its flanges entirely, the primary profiles are considerably weakened, reducing their moment of inertia and load-bearing capacity. For example, in a 45 / 48 / 45 C-shaped profile, the moment of inertia can be 2195931 of 34 can be reduced by up to one seventh when the perforation completely affects one of its wings. A particular case of mixed-level building structures is when the lower part of the profiles of both the primary and secondary structures are at the same level and coincide with the face of the flat product that forms the partition, ceiling, or enclosure. In mixed-level structures, the profiles of the primary structure interfere with the profiles of the secondary structure. When the bottom of the primary and secondary structural profiles are at the same level, the flat product can be attached to both the primary and secondary structural profiles, improving the mechanical performance of both profiles and increasing the effective spans between the profile support points for the same maximum deflection of the ceiling, partition, or enclosure. This improved mechanical performance also results in less deflection of the partition, ceiling, or enclosure with the same effective spans. Systems for joining ceiling and wall supports are known in the prior art, such as that described in patent US4208851A, which describes a fire-resistant suspended ceiling system in which the main beams have weakened joints that flex with thermal expansion. The ceiling support system has aligned, fixed beam elements spliced ​​together to absorb longitudinal compression, such as that resulting from thermal expansion during a fire. Each band end includes an axially outwardly extending tab for locking engagement with the adjacent beam element band and is configured such that the tabs fold longitudinally and turn laterally. They are displaced out of the normal plane of the tabs when the beam elements are longitudinally compressed toward each other. Consequently, the tabs shift laterally as they move toward each other in a longitudinal direction and may actually overlap each other longitudinally. 2195931 of 34 The cross beams are generally connected to the main beams through slots in the main beams, such as by a hook in a connector, as described in patents ES2240586T3 and ES2056916T3. Another example is patent EP1724407B1, which relates to a metal grid structure for a suspended ceiling, and more particularly to a connector in such a structure that helps keep the ceiling intact and from falling under its own weight during a fire. On the other hand, the placement of structures in two perpendicular directions is especially interesting in the specific case of roofs, but it is also applicable to vertical structures, such as wall cladding, high-rise partition walls, or lightweight facade enclosures. Furthermore, in the specific case of facade enclosures, due to the high wind loads they withstand, fire resistance factors, or burglary resistance factors, composite structures at the same level are especially interesting for their design. In all of the above cases, the inertia of the primary structural profiles must be maintained along the entire length of the profile to avoid oversizing. At the same time, the mechanical sizing of the primary profiles to support the required structural loads makes their dimensions significant, and therefore placing many of them in parallel and with small separation distances is not justified. To allow the primary profiles supporting functional loads to be separated from each other by, for example, 1,200 mm, the plasterboard or flat product must be reinforced with an auxiliary structure of lighter secondary profiles, perpendicular to the primary profiles. In this case, both structures are in the same plane and connected to each other. In these cases, the primary profiles placed in one direction provide structural rigidity to the system, while the secondary profiles, oriented in the other direction, provide better fixation of the plasterboards and provide greater rigidity to the boards to allow the primary profiles to be spaced further apart. 2195931 of 34 The mechanical strength of a profile is determined by its moment of inertia. In the case of large ceilings or walls, both structural profiles and auxiliary profiles must maintain their moment of inertia, avoiding deformations or perforations in their sections that could weaken them. The difficulty of creating building structures in two perpendicular directions, both at the same level, lies in the fact that the moment of inertial of the profiles must not be reduced in the areas where the profiles are joined, both in the joints between structural profiles and in the joints between auxiliary profiles and in the joints between structural profiles and auxiliary profiles. To avoid reducing the moment of inertia of structural profiles, perforations are only made in the profiles in the area of ​​their web and, more specifically, near the neutral fiber of the profiles. The strength of a profile and its deformation into a sag are significantly impaired if the connection between profiles is hinged. To ensure the mechanical strength of the profile is maintained, it is necessary to ensure that the connections between profiles maintain the highest possible degree of continuity of inertia, improving the level of joint embedment. The strength of the joint, in profiles with embedded-embedded joint at their support points, measured in terms of the deformation arrow “f” of the profile, for a uniformly distributed load, is given by: _ 1 q L4^EE= 384 The While the strength of the joint, in profiles with articulated-articulated joint at their support points, measured in terms of the deformation arrow f of the profile, for a uniformly distributed load, is given by: _ 5 q L4_ ^AA= 384 Ef =5xÍe-e 2195931 of 34 As can be seen, with the same inertial force "I" of the profile, the same length "L" of the profile, the same modulus of elasticity "E" of the material used in the profile, and the same load "q" applied to the profile, the deformation in terms of deflection "f" in the bi-hinged case is five times greater. For this reason, when the connections between profiles are bi-hinged, a profile with an inertia five times greater is required to obtain the same deformation as when the connections are bi-embedded. Traditionally, maintaining the profile's moment of inertia in the area where the profiles are joined is achieved by inserting these connecting pieces into the respective ends of the profiles to be joined, generating a large use of connecting pieces, screws and labor, and increasing the system cost. Installing a ceiling, partition, or façade enclosure requires aligning these profiles and precisely adjusting the distance between them. The plasterboard or flat element attached to these profiles has defined dimensions and tolerances. Primary profiles with perforations or shapes facilitate the alignment and adjustment of the spacing between the secondary profiles attached to the primary profile. Secondary profiles with perforations or shapes facilitate the alignment and adjustment of the spacing between the primary profiles attached to the secondary profile. The types of suspended ceilings and structures currently available on the market are highly diverse, both in terms of the materials used and the load-bearing capacity of the elements. In this regard, it is important to classify them into two categories: (1) those whose bearing capacity is uniform throughout their length and (2) those in which their bearing capacity is defined by longitudinal and / or transverse bearing sections, these bearing sections being delimited by surfaces with a lower bearing capacity. The first case would include, for example, continuous floors consisting of a concrete slab, and the second case would include, for example, floors made of concrete joists and ceramic vaults. Also included in the second case would be concrete waffle floors or the trusses supporting a roof or industrial warehouse. 2195931 of 34 The distribution of the load-bearing zones and the distance between these zones determines the layout of the primary structure and the distance between the fixing points of the primary structure to the load-bearing structure. Therefore, it is necessary to develop a simple structure, with fewer parts but still maintaining high strength, to allow its use in construction. Description of the invention The present invention relates to a profiling system for construction profiles, specifically in the field of mixed double construction structures at the same level. The purpose of this invention is to provide a practical and convenient system for joining construction profiles without the need to use connecting pieces such as screws, by means of a system for coupling the different profiles in a simple and durable manner. This invention makes it possible to connect profiles comprising at least one primary profile and at least one secondary profile, such that the connection is secured in all three spatial directions without the need for connecting pieces. In the proposed solution, the primary profile's moment of inertia "I" is maintained by avoiding perforations and deformations of the profiles in the sections remote from their neutral fiber, i.e., the curved material surface of an elongated part or plate, deformed by bending, which separates the compressed zone from the tension zone. This effect is especially important in structural (primary) profiles, in which the sections remote from the neutral fiber cannot be perforated or deformed, in order to preserve the structure's inertia. In the present solution, unlike the known state of the art, the improvement in the operating mode of the secondary profile is achieved by the union of three mechanisms: 2195931 of 34 A) using configurations that maintain the continuity of the profile in areas far from the neutral fiber, B) making their couplings in areas close to or coinciding with the primary profile, where the effort requested by the secondary profile is lower, and C) raising the height of the support points at the ends of the secondary profiles above the height of the primary profiles on which they rest, thus creating a negative pre-deflection, to reduce the maximum deflection created at the central point of the secondary profile with respect to the height of the primary profiles. This last mechanism is especially important in auxiliary (secondary) profiles, in which, due to their small dimensions, their moments of inertia are reduced and the deflection generated is high. Thus, in a preferred embodiment, the joint of the present invention comprises at least one primary profile and at least one first secondary profile. A primary element is located in each of the primary profiles and has at least one primary web with at least one perforation, and at least one primary flange, where the at least one primary web and / or the primary flange have a secondary profile locking tab. In a first embodiment, the primary element may have a basic L-shaped section, consisting of a primary web and a primary flange. However, other C-shaped sections are also acceptable, either with two primary webs (each having at least one perforation, aligned with one another) connected by a primary flange, or with two primary flanges flanking a primary web. In turn, the primary element may have a section with two primary webs and two primary flanges, having a square section, for example. Preferably, the primary profile has the same section as the primary element. Each perforation of the at least one primary web has a locking slot and a passage slot, the passage slot being penetrable by a first secondary element located in the first secondary profile to be joined. 2195931 of 34 In this way, since the perforation presents the passage and locking grooves, a sliding position and a locking position can be distinguished. Specifically, the passage slot, or sliding position, of the perforation of the primary web of the primary element allows one end of the first secondary element to be introduced through said perforation. By remaining in the passage slot, the end of the first secondary element is at a height level where said secondary element does not interfere with the primary web of the primary element, and can move freely in the longitudinal direction through the primary web of the first primary element. The separation between the two positions is achieved by a protrusion configured to hold the secondary element of the secondary profile in each position. Thus, a secondary element cannot directly access the locked position, but must be inserted into the offset position and elastically deformed to be able to transition from this initial position to the locked position, resulting in a clipped connection between the primary profile and the secondary profile. Each perforation in the primary element is located in areas close to the neutral grain of the primary profile, without affecting the primary flange. The distance between the perforations in the primary profile defines the spacing between the secondary profiles (secondary modulation - S). This spacing between perforations can also be a value equal to an integer divisor of the required spacing between secondary profiles. The first secondary element, located in the first secondary profile to be joined, has an end comprising a secondary web and at least one secondary flange, where said end is configured to be inserted into the perforation of the primary element. Said end of the first secondary element may have an L-shape. The perforation in the primary element has a design that allows a slight turning movement of the secondary element in the moving position. This turning movement can be achieved by having a certain amount of play in the moving position, which facilitates the entry of the secondary element. Alternatively, the end of the first secondary element may have a shape similar to a "C." 2195931 of 34 with a secondary web and two secondary wings. This configuration, despite having greater rigidity, allows movement from a traveling position to a locked position, equivalent to the L-shaped configuration. In a preferred embodiment, the secondary profile has the same cross-section as the secondary element. Thanks to this configuration, the secondary profile can completely pass through the perforation of the primary element. Optionally, in a preferred embodiment of the present invention, the secondary elements may have a geometry that incorporates two flanges on their secondary wings, either oriented inward or outward, presenting a C or omega shape, respectively. In this type of configuration, with two secondary wings and one flange on each of them, the flanges of the secondary wings of the first secondary element may be in the same plane by being arranged at a specific angle. In turn, the lateral flanges may be found exclusively on the secondary element or be formed as part of the entire secondary profile. Additionally, the first secondary element has at least one slot or shape that affects its secondary web, the secondary flanges, or both, each slot or shape configured to be penetrated by the primary element of each of the primary profiles and block the entry displacement of the first secondary element through the perforation. Unlike the slot, where part of the secondary element is removed, the shape presents a deformation of the element, maintaining the section of the secondary element continuous. Thus, the shaping option prevents the element from breaking, thus avoiding weakening and reducing the moment of inertia of the system. To overcome the displacement zone, an intense rotation is required, elastically deforming the secondary element and allowing it to overcome the existing protrusion between the grooves. However, to reach the locked position, it is necessary that the secondary element be previously aligned with each of the primary elements of the different primary profiles existing in the system. That is, prior to performing the intense rotation, at least one groove or conformation of the 2195931 of 34 the first secondary element must be aligned with each of the primary elements, so that they penetrate said slot or conformation, allowing rotation. Additionally, in a preferred embodiment, the connection is made with three profiles, where two secondary profiles are joined to a primary profile. In this regard, the profile system has a second secondary element located in a second secondary profile to be joined, where said second secondary element has one end that can be coupled to the end of the first secondary element. This coupling may be a narrowing of the end of the second secondary element whose outer geometry coincides with the inner geometry of the first secondary element, such that the end of the second secondary element can be rigidly inserted into the end of the first secondary element. Equivalently, the coupling between the two secondary elements can be carried out by narrowing the end of the first secondary element, which is then inserted into the end of the second secondary element. In turn, a lock is optionally established between these two secondary elements by means of a means configured to prevent the first and second secondary elements from separating once the coupling has been completed. This means may consist of a tongue-and-groove joint between these elements. Thus, a configuration can be found where the second secondary element comprises a protrusion at the end of the flange of its secondary flange, which corresponds to a space in the flange of the secondary flange of the first secondary element. Alternatively, the connection can be arranged in the secondary web or the secondary flange of the secondary elements. Additionally, the second secondary element also comprises a groove or shape in its secondary web. Both, whether a groove or a shape, are configured to match the tab located on the primary element once the secondary elements are positioned in the locking groove, reaching the locked position of the primary element. In this way, the 2195931 of 34 fastening of the secondary elements to the primary element, preventing further entry of the first secondary element through the perforation of the primary element. Thus, as has been described, there are two positions, displacement and blocking, of the secondary elements with respect to the primary element. First, there is a raised or initial position, where the end of the first secondary element has passed through the bore of the primary element's web located in at least one primary profile, depending on the length of the first secondary profile and the number of primary profiles it can reach, and is in the sliding position. In this position, the first secondary element can move through the primary element to a greater or lesser extent. This aspect is of great relevance in those designs with three profiles, where the greater or lesser entry of the first secondary element facilitates the coupling with the second secondary element, which translates into greater ease for the user to install this system. Thus, in three-profile connections, once the two secondary elements are coupled, they can move to the second, or locked, position, where said secondary elements remain aligned with the primary element and secured to each other. To do this, they deform elastically so that they can overcome the existing protrusion on the primary element, thus aligning at least the first secondary profile with the primary profile. In this way, once the first and second secondary elements of the first and second secondary profile, respectively, are coupled, they can be moved to the locked position, where the first secondary profile is aligned with the primary profile. Additionally, in order to continue the installation of the profile system, the second secondary profile may additionally contain an element, equivalent to the first secondary element of the first secondary profile, located at the supplementary end of the second secondary element of the second secondary profile. 2195931 of 34 The alignment of the second secondary profile is achieved by aligning the following primary profile. That is, the insertion of the supplementary end of the second secondary profile into a subsequent primary element located at a primary modulation distance L (or an integer multiple of the distance L), equivalent to the insertion of the first secondary element of the first secondary profile into the primary element, allows the alignment of the second secondary profile with the subsequent primary profile. Additionally, to achieve greater fixation of the secondary elements to the primary element, the joining system has an additional fastener configured for such locking, by means of the tab located on the primary wing of the primary element entering the slot or shape located on the second secondary element. In this way, the displacement of said elements relative to the primary element is prevented. In a preferred embodiment, the first secondary element also has a slot or shape that coincides with the tab located on the primary wing of the primary element, favoring the fixation of this first secondary element relative to the primary element. Alternatively or in conjunction with the joining of the two secondary elements with the flange of the primary wing of the primary element, the joining system may comprise a second fastening of the secondary elements with the primary element. In this case, the second secondary element has a second groove or shape that penetrates the web of the primary element when the secondary elements meet in the locking groove, blocking the first and second secondary elements from moving longitudinally across the web of the element. Again, the first secondary element may comprise a groove or shape that penetrates the web of the primary element, increasing the holding power of the connecting system elements. However, depending on the connection between the first and second secondary elements, the end of the second secondary element does not reach the primary web of the primary element. In this case, the groove or shape in the first secondary element penetrates directly into the primary web of the primary element, blocking the movement of this secondary element directly. 2195931 of 34 Considering the multiple acceptable possibilities for the individual configuration between these profiles, the area of ​​the primary web of the primary element where it is penetrated by at least one of the secondary elements, whether the first secondary element or both, will depend on the type of groove or conformation existing in the secondary elements. Thus, in embodiments where the grooves or shapes of the secondary elements are located along the entire web and part of the secondary flanges of the elements, the area is uniform and continuous. However, in those embodiments where the groove of the secondary elements is located in a portion of the secondary web of the secondary elements, the primary element will also comprise a protrusion on its primary web that coincides with the groove of the secondary elements. Therefore, the joining system can provide dual attachment of the two secondary elements to the primary element, by means of a tab located in the primary flange of the primary element, or in the web area of ​​the primary element. Thus, in a preferred embodiment of the system, a configuration is presented with a fastening means that includes both fasteners. The perforation of the primary element's web, as well as the type of slot or shape present in the secondary elements, determines the distance between the primary flange of the primary element and the flange or secondary web of the first secondary element, once the first secondary element has been accommodated in the locking groove of the perforation. This height can be defined so that the secondary flange of the secondary element rests on the primary flange of the primary element. In an alternative embodiment, this height can also be adjusted so that the secondary flange of the first secondary element is raised with respect to the primary flange of the primary element, allowing that when the secondary profile is deformed it does not totally or partially exceed the plane defined by the primary profiles. This configuration is important for achieving less deformation and greater flatness of the flat products that make up the roof, partition, or façade enclosure, depending on the loads applied to them. 2195931 of 34 As an illustrative example, if the maximum deformation of the secondary profile is F and the minimum is 0, measured in terms of deflection, by moving the perforation F / 2 it is possible to achieve that the deflection in the center of the secondary profile oscillates between a minimum of -F / 2 and a maximum of F / 2 with respect to the plane defined by the primary profiles. In a preferred embodiment, when the end of the second secondary profile is coupled to the end of the first secondary profile, the groove or shape of the first secondary element is separated from a groove or shape of the second secondary element by a distance equivalent to the length of the primary flange of the primary element. In this way, the double fastening corresponds to the web and the flange located at the end of the primary element. The installation of a building structure comprising the joining system described above can be carried out by placing primary profiles in parallel, such that the secondary profiles, arranged perpendicular to these, will form a plane on which the plasterboards that make up the ceiling, wall or any other equivalent enclosure rest. In this sense, in a second aspect of the invention, the installation procedure of the profile system described above is composed of the following steps: a) Entry of the end of the first secondary element, through the passage slot, into the perforation present in the primary web of the primary element of at least one primary profile. Through this insertion, the first secondary element is inserted through the passage slot into the sliding position of the primary element. This sliding position presents a slight clearance that allows the first secondary element to rotate slightly. Additionally, the secondary web of the first secondary element does not interfere with the primary web of the primary element, allowing it to advance freely along the first secondary element and facilitate its connection to the second secondary element. 2195931 of 34 b) Alignment of the groove or conformation of the end of the first secondary profile with the locking tab of the primary element of the at least one primary profile. At this stage, the secondary element is positioned relative to the primary element, allowing penetration of the primary element's tab into the slot or formation of the first secondary element. c) Moving, preferably by rotating, the first secondary element from the passage slot to the locking slot, the first element moving from the sliding position to the locking position, simultaneously inserting the locking tab of the primary element into the slot or shape of the first secondary element. In a preferred embodiment, the first secondary element further comprises a means for restricting its entry through the perforation of the primary core of the primary element. This means may be a tongue-and-groove joint between the first secondary element and the primary element. Thus, in a preferred embodiment, the tongue-and-groove joint consists of a groove or shape located, preferably, in the web and part of the secondary flange of the first secondary element. In this way, said groove or shape is penetrated by the primary web of the primary element, limiting the movement of the first secondary element in a manner complementary to the flange present in the primary flange of the primary element, which limits the movement of the second secondary element. In the case of a slot located in part of the secondary web of the first secondary element, the web of the primary element may have a protrusion on its primary web coinciding with the slot of the first secondary element. Therefore, step b) of aligning the secondary and primary element is carried out by adjusting the slot or shape of the first secondary element with the locking tab of the primary element. 2195931 of 34 Additionally, the installation process for a profile system may include an additional step, consisting of the coupling of two ends of secondary elements. In this three-profile connection configuration, the coupling of the secondary profiles occurs once the first secondary element has been inserted into the opening (step a). This can be done either before aligning the secondary element (step b) or after the first secondary element has been placed in its locked position, thanks to the folding capacity of the primary element's primary wing. In this way, through the joints described in the present invention, a reduction of the maximum deflection of the system of up to 50% is achieved, due to the effect of the pre-deflections at the support points of the secondary elements on the primary element, creating a small negative deflection when the system is not loaded, to a small positive deflection when the system is loaded. Additionally, the present invention also provides a reduction in the number of hang-ups. Depending on the embodiments used, a reduction of between 50% and 70% is achieved, as a result of the effect of the double structure working at the same level, without affecting the moment of inertia of the primary profiles. Thus, unlike the current state of the art, a system has been achieved that offers significant advantages. According to the present invention, the use of connecting pieces at the respective ends of the profiles is not required, since the connecting elements are included in the profiles themselves. This avoids the need for a number of parts to join these systems, reducing the cost of these parts and the labor required. The following elements are shown in the figures: 1. Primary profile 10.

Furthermore, the present invention covers all possible combinations of particular and preferred embodiments indicated herein. 2195931 of 34 Brief description of the drawings Next, to facilitate the understanding of the invention, by way of illustration, but not limitation, an embodiment of the invention will be described which makes reference to a figure. Figure 1 shows a perspective view of a profile system with a construction structure comprising two primary profiles and multiple secondary profiles.

Firstly, it can be seen how a single secondary profile (2) is joined to two primary profiles (1), whilst the lower part includes the connection between two secondary profiles (2, 2'), coinciding with the two primary profiles (1) joined with a single secondary profile (2). In this way, each secondary profile (2) comprises a first secondary element (20), which can cross a primary element (10), located in each of the primary profiles (1) of the construction structure. The preferred configuration of the construction structure consists of at least one primary profile (1) located at a distance L, or an integer multiple of L, from another subsequent primary profile (1), present in the construction structure. In an alternative embodiment, where the first secondary profile (2) does not have a sufficient length, each perforation of the primary profile (1) serves as a connection to a first secondary profile (2), coupled with a second secondary profile (2'), preferably arranged perpendicular to the primary profile (1), giving rise to a construction structure capable of supporting a flat construction product, such as a plasterboard, used for the construction of a ceiling, wall or façade enclosure. This coupling between several secondary profiles (2, 2') is carried out between the longitudinal ends (25, 25') of a first secondary element (20) and a second secondary element (20'), located in each of the secondary profiles. These longitudinal ends (25, 25') have a configuration such that they can be fitted into one another. Thus, in an embodiment with L-shaped elements, the longitudinal ends (25, 25') of the secondary elements (20, 20') can each have a complementary termination and be fitted into one another, obtaining a checkerboard-shaped joint. Figure 2 shows an embodiment of the union of a primary element (10) and a 2195931 of 34 set consisting of five secondary profiles (2) with a first secondary element (20) in the shape of an L in each of the five secondary profiles (2). In this figure, a primary element (10) can be seen specifically, which comprises five perforations (12) in its primary core (11), where a first secondary element (20) is inserted in each of the five perforations (12). Thus, each perforation (12) is configured to be penetrated by a first secondary element (20), and a sliding position and a locking position are distinguished therein, which are separated by a transition projection (17). Additionally, the perforation (12) comprises a locking tab (16) configured to fix the position of the first secondary element (20). In the present embodiment, the locking tab (16) is located on the side of the perforation (12), coinciding with the secondary wing (22) of the first secondary element (20). Alternatively, this locking tab (16) may be designed to correspond to the secondary web (21) of the secondary element or even both, the locking tab (16) being located at the corner of the perforation (12). For its part, in the present figure, first secondary elements (20) are shown along different positions during their installation. Firstly, located on the left of the figure, a first secondary element (20) is inserted into the displacement position (14). This is the first stage of the installation, where the longitudinal end (25) of the first secondary element (20) is inserted into the perforation (12) of the primary element (10). Next, it can be seen how the first secondary element (20) presents a small turning movement, due to the certain clearance that the displacement position (14) of the perforation (12) presents. This displacement allows the first secondary element (10) to rest on the locking tab (16) and continue the longitudinal displacement within the perforation (12). The next step is the alignment of the slot (24) of the first secondary element (20) with the locking tab (16). In this specific embodiment, said locking tab 2195931 of 34 lock (16) is located on the side of the perforation (12) coinciding with the slot (24) located in the secondary wing (22) of the first secondary element (20). The arrangement of the locking tab (16) in the perforation (12) determines the presence of the slot (24) in the secondary web (21) or secondary wing (22), or even in both at the same time. Alternatively, the slot (24) can be replaced by a shape that allows the locking tab (16) to enter in a manner equivalent to the slot (24), but unlike the latter, it maintains the continuity of the section of the secondary element (20). Once the slot (24) or conformation has been aligned with the locking tab (16) in the longitudinal direction of the first secondary element (20), as a result of the small turning movement, the slot (24) of the first secondary element (20) coincides with the locking tab (16) of the primary element (10), with the locking tab (16) entering into the slot (24) and blocking the longitudinal advance of the first secondary element (10). In this position, by means of a more intense turning of the first secondary element (20), causing the deformation of the geometry of the secondary profile, the transition projection (17) is exceeded. The transition projection (17) is configured to allow the first secondary element (20) to easily tilt by rotation from the passage slot (14) to the locking slot (13), once the slot (24) is aligned on the locking tab (16), and also to prevent the first secondary element (20) from being able to reverse said tilt by rotation from the locking slot (13) to the passage slot (14). The use of thin profiles is therefore preferable. That is to say, in the present invention it is advisable to use profiles whose thickness allows a deformation of their geometry that allows the secondary profile to be tilted from the sliding position to the locked position. In an alternative embodiment, suitable for thicker profiles, the first secondary element (20) has a local weakening, where it coincides with the transition projection (17), which allows local deformation of the profile geometry when the transition projection (17) is exceeded. 2195931 of 34 Finally, the first secondary element (20) sits on the perforation (12) of the primary element (10), reaching the locking groove (13), where the assembly of the two profiles, through the primary element (10) and secondary element (20), remains stable, preventing the union from being released by rotation or vertical displacement of the first secondary element (20). Only by a change in the geometry of the secondary profile, expressly forced, can both profiles be disassembled. During this installation process, by being able to support the first secondary element (20) on the locking tab (16) during its entry, the manipulation by the user is facilitated during the entry process of the longitudinal end (25) of the first secondary element (20) and the determination of the alignment of the slot (24) or conformation of this first secondary element (20) with the locking tab (16), which is carried out automatically during the movement once the slot (24) or conformation reaches the locking tab (16), moving the secondary element (20) from the sliding position to the locked position. Alternatively, the locking tab (16) could be located along the primary flange (15) of the primary element (10), allowing a locking tab (16) to correspond to the multiple perforations (12) present in the primary web (11). From a functional standpoint, the present invention facilitates the alignment of primary and secondary profiles from a distance (more than 1 meter) since it converts a precision operation, such as securing the slot, into a smooth sliding and rotating operation of the profile from a distance (self-aligning the profile). This translates into a significant improvement over current solutions for installing ceilings and partitions, allowing an installer to assemble several profiles without having to go down, move the ladder, and then go back up. In practice, it has been proven that an installer can install more than 6 secondary profiles, equivalent to a total profile length of more than 8 meters, without moving from a given position. It has also been proven that with a gentle turning torque, less than that required to open a door handle, the transition of the first secondary element from the passage groove to the locking groove is achieved. Figures 3a and 3b show a preferred embodiment of the coupling in perspective. 2195931 of 34 of two C-shaped secondary elements (20, 20') of the profile system with a fixing slot (24, 24') each. Again, the slots (24, 24') can be replaced by a conformation. Unlike the previous figure, where the connection between two profiles was seen, a primary element (10) with a secondary element (20) in the form of an L, in this figure the coupling of two secondary profiles (20, 20') in the form of a C can be seen. This coupling is necessary in order to maintain the continuity of the secondary profiles (2, 2') along the construction structure, which comprises several primary profiles (1). In this way, the second secondary profile (2') will act as the first secondary profile, with a first secondary element configured to be introduced into the perforation (12) of the next primary profile (1), and the next second secondary profile will be incorporated. First, Figure 3a shows these two secondary elements (20, 20') separately, while Figure 3b shows the coupling of the longitudinal ends (25, 25') of these secondary elements (20, 20'). As an alternative to the checkerboard-shaped longitudinal ends (25, 25'), the first secondary element (20) located in the first secondary profile (2) has a longitudinal end (25) with a narrowing. This narrowing is designed to be inserted into the longitudinal end (25') of the second secondary element (20') located in the second secondary profile (2'). On the other hand, the presence of a fastener (41) can be seen, comprising a slot (24, 24') in each of the secondary elements (20, 20'). In this way, the slot (24) of the first secondary element (20) is configured to be penetrated by a first locking tab (16) located in the primary web (11) of the primary element (10), while the slot (24') corresponding to the second secondary element (20') coincides with a second locking tab (16) present in the primary wing (15) of the primary element (10). In this particular embodiment, as can be seen in the figure, the slot (24) is located along the entire secondary web (21) and part of the secondary wings (22) of the first secondary element (20). For this reason, the area of ​​the primary web (11) of the 2195931 of 34 primary element (10) that penetrates the slot (24) acts as a whole as a locking tab (16), being a uniform area that can extend from one side to the other of the perforation (12), without the need for an additional tab. Said tab is presented in those embodiments where the slot (24) is located only in a part of the secondary web (21) or secondary wing (22) of the first secondary element (20) as could be seen in Figure 2. Similarly, the locking tab (16) of the primary wing (15) of the primary element (10) can have different configurations depending on the slot (24') existing in the second secondary element (20'). Figures 4a and 4b show a preferred perspective embodiment of the coupling of two secondary elements of the profile system (4), where the first secondary element (20) comprises two fixing slots (24). In this sense, unlike the previous case, in the present embodiment, the longitudinal end (25') of the second secondary element (20') passes through the perforation (12) of the primary core (11) of the primary element (10) in the opposite direction to the first secondary element (20). Thus, the second slot (24') of the second secondary element (20') is arranged at such a distance from the first slot (24') of the second secondary element (20') that it is also penetrated by the locking tab (16) located in the primary web (11) of the primary element (10) during the locking position of the secondary elements (20, 20'). Therefore, a greater fixation of the system is achieved, by fixing the position of the two secondary elements (20, 20') by means of the penetration of the slots (24, 24') in the primary web (11) of the primary element (10). In an alternative embodiment, the slot (24) located in the first secondary element (20) and the slot (24') located in the second secondary element (20') in the overlapping area between both secondary elements are penetrated simultaneously by a single locking tab (16) located in the web of the primary element (10). In this case, a second locking tab (16) located on the primary wing (15) of the primary element (10) is not necessary to perform the fixing. Additionally, it can be seen how the fixation between the first and second element 2195931 of 34 secondary elements (20, 20') can be made by means of a locking means (42). This locking means (42) is an optional tongue and groove joint located in the wings of both elements. This joint would be found, once placed together with the primary element (1), on the outside of the gap generated by the primary core (11) and the primary wings (15) of the primary element (10). For fixing the secondary elements (20, 20'), there is a fixation between these two secondary elements by means of a locking means (42) configured to prevent the separation of the first and second secondary elements (20, 20') once the coupling has been carried out. Preferably, the locking means (42) is a tongue and groove joint between both secondary elements (20, 20'). Figures 5a and 5b show the union of the first and second secondary elements (20, 20'), with special detail of the slots (24, 24') found in said elements, with the primary element (10). Thus, firstly, in figure 5a, the connection between secondary elements (20, 20') can be seen inside the space generated by the primary core (11) and the locking tab (16) at the end of the primary wing (15) of the primary element (10). On the other hand, in figure 5b, it can be seen how the connection of the secondary elements (20, 20') has an external connection to the primary element (10). In this figure, the possibility of a locking tab (16) can be seen, located along the primary wing (15) of the primary element (10), capable of locking the secondary elements (20, 20') of multiple perforations (12) present in the primary core (11). As can be seen in these diagrams, the present profile system (4) achieves a connection between the primary (10) and secondary (20, 20') profiles at the same height, generating a surface suitable for joining other compounds such as plasterboards that make up a ceiling, a wall or a wall enclosure. Figures 6a, 6b, 6c and 6d show a section of the system in which the different stages of the assembly procedure of the secondary elements (20, 20') in the form of a C and in the form of an omega with the primary profile can be distinguished. 2195931 of 34 Firstly, Figures 6a and 6b show an embodiment of the first secondary element (20) in the form of a C. In this configuration, the tab (23) of the wing of the first secondary element (20) is oriented inwards, so that the primary element (10) has the locking and passage slot (13, 14) in an area contained within the perforation (12) of the primary element (10), that is, between the secondary wings (22) of the secondary element (20). Figures 6c and 6d show an embodiment of the first secondary element (20) in the form of an omega. In this case, the locking and passage grooves (13, 14) are located on the outside of the perforation (12) of the primary element (10). As a whole, Figure 6 shows the adjustment and locking process of the first secondary element (20). Initially, the first secondary element (20) passes through the perforation (12) present in the primary core (11) of the primary element (10), making the tabs (23) of the secondary wings (22) of the first secondary element (20) coincide with the passage slot (14), reaching the sliding position. In this position, the secondary web (21) of the first secondary element (20) does not interfere with the primary web (11) of the primary element (10). In this way, the first secondary element (20) can advance through the perforation (12) of the primary element (10) without any type of limitation. This advance favors the subsequent coupling of the first secondary element (20) with the second secondary element (20') since the primary element (10) does not interfere with said union. In this embodiment, the first secondary element (20) comprises a slot (24) configured to be inserted into the core of the primary element (10). The slot (24), once aligned with the primary core (11), acting as a locking tab (16) of the primary element (10), allows the first secondary element (20) to move from the passage slot (14) of the primary element (10) to the locking slot (13) of said element. 2195931 of 34 Similarly, the alignment and adjustment of the slot (24'), located in the second secondary element (30), with respect to the locking tab (16) of the primary wing (15) of the primary element (10) and, depending on the configuration of the second secondary element (20'), of the primary web (11) in the embodiment with two slots (34) can be carried out. Also in a similar manner, the transition projection (17) is configured to allow the first secondary element (20) to easily tilt by turning from the passage groove (14) to the locking groove (13), once the slot (24) is aligned on the locking tab (16), although in this case, because there are double passage grooves (14) and locking grooves (13), a first intense rotation in one direction and a second intense rotation in the opposite direction are required to overcome both transition projections (17). The transition projection (17) is also configured to prevent the first secondary element (20) from reversing said tilting by turning from the locking groove (13) to the passage groove (14). Figure 7 shows a perspective view of the profile system (4) for a building structure. This system comprises the primary element (10) and the two secondary elements (20, 20'). As can be seen in Figure 6, the secondary elements (20, 20') are in a locked position in all three dimensions. On the one hand, a primary profile (1) can be seen comprising a primary element (10) with a perforation (12). This perforation (12) is located in the primary web (11) of the primary element (10) and comprises two passage grooves (14) and two locking grooves (13). In this embodiment, the grooves (13, 14) are located on the inside of the perforation (12) due to the C-shaped configuration of the secondary elements (20, 20'), where the tabs (23) of the secondary wings (22) of the first secondary element (20) are oriented in this direction. Optionally, the locking means (42) between the longitudinal ends (25, 25'), which can be coupled together, of the secondary elements (20, 20') can be located inside the space of the primary element (10). In this case, the narrowing area to facilitate coupling is located at the longitudinal end (25') of the second secondary element (30) and both secondary elements (20, 20') in this case have a single fixing slot (24, 24'), although, as previously described, the profile system (4) can have other 2195931 of 34 configurations equally suitable for the development of the present invention. These slots (24, 24') are aligned with the locking tab (16) of the primary web (11) and the primary wing (15) of the primary element (10), respectively. In this way, when the secondary elements (20, 20') are located in the locking slot (13), said slots (24, 24') block the advance of the first and second secondary elements (20, 20'), respectively, through the perforation (12) of the primary element (10), achieving a fastening (41) of the profile system (4) in the three directions. Figures 8a, 8b, 8c and 8d show the stages of the assembly procedure of two secondary profiles (2, 3) with the primary profile (1). In this case, a primary element (10) is represented with two primary webs (11, 11'), a first primary web (11) and a second primary web (11'), where each primary web (11, 11') has a perforation (12), and two primary wings (15, 15') joined to the two primary webs (11, 11') forming a square section. Firstly, the entry of the first secondary element (20), located in the first secondary profile (2), can be seen through the perforation (12) of the primary web (11) of the primary element (10), located in the primary profile (1). In an embodiment similar to that shown in Figure 7, the entry of the first secondary element (20) is carried out by placing the tab (23) in the passage slits (14) of the perforation (12). In this way, by being located at a higher height, the secondary web (21) of the first secondary element (20) does not interfere with the primary web (11) of the primary element (10), and can advance through the perforation (12) without limitation. As a complement to the previously described installation process in a first secondary element (20) and a primary element (10), in this position, the second secondary element (20') is coupled to the end of the first secondary element (20). The connection between these profiles (2, 2') is carried out by means of the coupleable longitudinal ends (25, 25') of the secondary elements (20, 20'). On this occasion, the second secondary element (20') crosses the primary web (11'), and is coupled with the first secondary element (20) inside the primary element (10). 2195931 of 34 In a preferred embodiment, the profile system (4) has a narrowing at one of the ends of the secondary elements (20, 20'), which allows the entry of said element into the longitudinal end of the other secondary element. In this case, the narrowing is located in the second secondary element (20') 5 Additionally, optionally, the profile system (4) has a locking means (42) between the secondary elements (20, 20'). This locking means (42) can be a tongue and groove joint that limits its movement, once the coupling has been carried out. This joint can have different configurations 10 such as, for example, a projection at the end of one of the tabs (23, 23') of a secondary element (20, 20') that coincides with a space in the tab of the other secondary element (20, 20') or a projection on the wing of a secondary element coinciding with the wing of the opposite secondary element. Next, once the connection between the secondary elements (20, 20') has been established and secured, the alignment of said secondary elements (20, 20') with the primary element (10) is carried out. The alignment consists of placing the secondary elements (20, 20') in such a way that the fastener (41) can be formed between the primary element (10) and the secondary elements (20, 20'). In a preferred embodiment, the slot (24') is located in the secondary web (21') and part of the secondary wing (22') of the second secondary element (20'), such that the locking tab (16) covers the entire length of the primary wing (15) of the primary element (10). Additionally, in this embodiment it can be seen how the first secondary element (20) also comprises a slot (24) in its secondary web (21) and part of its secondary flange (22). The slot (24) of the first secondary element (20) is configured to match the locking tab (16) located in the primary web (11) of the primary element (10). Therefore, in this embodiment, the alignment of the secondary elements (20, 20') is carried out by matching the slot (24, 24') of the first and second secondary elements (20, 20') respectively with the locking tab (16) of the primary web 35 (11) and the locking tab (16) of the primary wing end (15) of the primary element 2195931 of 34 (10). That is, the distance between the slot (24) of the first secondary profile (20) and the slot (24') of the second secondary profile (20'), when the two secondary elements (20, 20') are coupled, is equal to the distance (D) between the primary web (11) of the primary profile (1) and the locking tab (16) of the end of the primary wing (15) of said profile (1). Finally, the presence of these slots allows the secondary elements (20, 20') to be fixed to the primary element (10) by moving said secondary elements (20, 20') from the passage slot (14) to the locking slot (13). Thus, when the position of the secondary elements (20, 20') is lowered to the locking slot (13), interference occurs between the primary web (11) and the locking tab (16) of the primary wing (15) of the primary element (10) with the secondary web (21, 21') of the secondary elements (20, 20'), blocking the movement of the latter. As can be seen above, in the preferred embodiment with two secondary wings (22, 22') with a tab (23, 23') on each one in the secondary elements (20, 20'), the movement towards the locking grooves is in turn a sequential movement. This sequential movement is carried out by means of the rotation of the first secondary element (20) or by the assembly formed by the secondary elements (20, 20'). Alternatively, the second secondary element (20') can be coupled to the first secondary element (20) once the latter is in the locked position. To do this, the wing of the primary element (10) has a certain degree of tilting. Through this tilting, the locking tab (16) located on the wing of the primary element (10) does not interfere with the end of the first secondary element (20), allowing the union of both secondary elements (20, 20') and their fixation once the locking tab (16) returns to the position prior to tilting. Furthermore, construction structures can be obtained with multiple primary profiles (1), separated by a distance corresponding to the primary modulation - L, joined to a first secondary profile (2) or to the assembly formed by the coupling of a first and second secondary profile (2, 2'). In the same way, building structures with multiple profiles can be obtained. 2195931 of 34 secondary profiles (2) or assemblies formed by the coupling of a first and second secondary profile (2, 2') joined to a first primary profile (1). The distance between the secondary profiles (2) is determined by the secondary modulation (S), which is determined by the distance separating two consecutive perforations (12) of the 5 primary elements (10), The primary modulation L is an integer divisor of the length of the flat product that is fixed to the structure, typically 1,200 mm for 2,400 mm long products and the secondary modulation (S) is an integer divisor of the width of the flat product that is fixed to the structure, typically 600 mm, for 1,200 mm wide products. Therefore, through the present joining system and its installation procedure, an improvement in the construction structures is achieved, facilitating the installation and reducing, or even completely eliminating, the number of joining pieces used during said installation. 2195931 of 34 CLARKE MODET & CO.
