    Removable and adjustable angle joint system for square tube profiles, by means of which the face of one of the profiles (1) is joined to the face of the other (2). This system consists of two groups of four flanges, two of them simple flanges (3) and the other two adjustable flanges (4), placed on the edges of each of the profiles to be joined (1, 2) and coupled together using screws (10, 11) and nuts (13). In this way, the independent tightening of each of the profiles (1, 2) is ensured, to be subsequently joined together by the fastening means (12, 13) placed on the slits (9) of the adjustable flanges (4), which allow the regulation of the angle of unión (α) between the profiles of square tube (1, 2).

    REMOVABLE SYSTEM FOR ADJUSTABLE JOINT IN SQUARE TUBE PROFILE ANGLE SECTOR OF THE TECHNIQUE
    The present invention has application in the field of UnioneS metal structures, specifically in the assembly of square section tube profiles. BACKGROUND OF THE INVENTION
    10 There are numerous types of bonding, such as the use of adhesives, the use rivets, interference adjustment, etc. However, currently, to join pieces of metal structures, such as square tube profiles, welding and / or assembly using bolted joints are used as a general rule.
    The union by welding provides great resistance, however, the problem
    15 arises when the need to reconfigure the structure arises. Today, this option is not possible, since no reconfiguration method is known to carry it out and, in addition, the cost of recovering the profiles is very high, compared to the acquisition of new ones. This is why the union by welding is considered permanent or not removable.
    20 Bolted joints, however, are removable, which does not imply the absence of inconveniences. The most notable of these is the need to machine the holes in the profile, not forgetting the use of base plates for the preparation of the surface of the profiles to be joined. In addition to these requirements, this type of joint is characterized by low versatility, as it is designed for a configuration
    25, limiting its regulation, especially as regards the angle of connection between the profiles.
    Currently there are disclosures of joining systems for square tube profiles, such as: GB 737693 A, US 1710842 A, WO 2004113634 A1 and EP 0833064 A2, however when it comes to angle-adjustable joints, no system is known union that meets the following characteristics: a) no prior preparation of the profiles to be joined is needed, b) it is a fully system

    Detachable, c) allow the total variation of the angle of union between the profiles, without changing the union system used. EXPLANATION OF THE INVENTION
    The present invention (Figure 1) describes a removable and adjustable angle connection system (a) for square tube profiles (1, 2). This system consists of two groups of four flanges, two single flanges (3, see Figure 2) and two adjustable flanges (4, see Figure 3) mounted on each of the profiles (1, 2).
    Simple flanges (3, see Figure 2) are in the form of a step, so that they adapt perfectly to the edges of the profiles to be joined (1, 2). In addition, they are provided with two side flanges (5) with their corresponding holes (6), thus allowing the passage of the screws (11) with their corresponding nuts (13), which are the fastening means used (see Figure 1).
    The adjustable flanges (4, see Figure 3), are those that allow the joining of the faces of the profiles to be joined (1,2). This is possible thanks to the semicircular plate (14) of which it is provided, in which there are also strategically placed torn (9). These torn (9) are those that allow the total regulation of the angle of union (a) between both profiles (1, 2), thus complying with the most outstanding feature of the joint system presented. In addition, these adjustable flanges (4), are also provided with side flanges (7) with their corresponding holes
    (8) to, together with the clamping means (10, 11, 13, see Figure 1), allow the independent mooring of each group of flanges (3, 4) in the profiles to be joined (1, 2).
    As a consequence, with the system described (see Figure 1), it is possible to make removable joints at a fully adjustable angle (a) between two square tube profiles (1, 2). In this way, with a single joint system, any angle of union between O and 1800 is achieved (see Figures 8,9,10,11 and 12). In addition, its easy assembly and disassembly, guarantees the possibility of reuse of the parts involved in the union, such as profiles (1, 2) and flanges (3, 4), without the need to perform previous operations on the profiles.

    A preferred embodiment of the invention is described below, taking as a reference the numbering adopted in the figures.
    The joint system described consists of a total of two groups of four flanges, where two of them are single flanges (3, Figure 2) and the other two are adjustable flanges (4, Figure 3). Each group is mounted independently on the profiles to be joined (1, 2) as follows (see Figure 4): each of the flanges (3, 4) is placed on the corresponding edge of one of the profiles (1) and , subsequently, they are fixed between them by means of fastening means used, screws (10, 11) and nuts (13), which pass through the holes (6, 8) provided on the side flanges (5, 7) of each flange. Applying the corresponding preload to the screws (10, 11) each group of flanges (3,4) is perfectly anchored to the profile (1) (see Figure 5).
    Once the previous steps have been carried out in each of the profiles to be joined (1, 2), both profiles are joined together (see Figure 6). For this, the adjustable flanges (4) are used, facing those of each of the groups and guiding them in such a way that the desired joint angle (a) is achieved. Subsequently, they are fixed with screws (12) and nuts (13) that are inserted in the tears (9), placed in said adjustable flanges (4) (see Figure 7). Thanks to its arrangement, we can achieve any angle of union (a) between the profiles to be joined (1, 2).
