    Detachable connection system for metal beams flush with the upper part, characterized by the use of a main support plate (1) and a secondary support plate (2). These plates are provided with slits (3, 4) that make it possible to join different sizes of standard i profiles. For this, in addition to the aforementioned, there is a need for fixing clips (5), with their corresponding screws (6), nuts (7) and washers (8). The main support plate (1) is also provided with side flanges (10) with slits (11), which are those that allow to adjust the height for different sizes of metal profiles. By inserting the tightening screws (15), by the slits (11) and holes (14), they allow to adjust the height between the beams so that they are flush at the top. The adjusting screws (16), which are mounted on the threads (21) of the main support plate, allow to adjust the height accurately before tightening the clamping screws (15) firmly. In addition, placing stiffening screws (18) on the holes (19) of the main support plate (1) could transmit the bending moments of the secondary beam (12), which become torsion on the main beam (9). ).

    REMOVABLE JOINT SYSTEM BY STAPLES FOR BEAMSPROFILE METALS FITED BY THE TOP SECTOR OF THE TECHNIQUE
    The present invention relates to a removable joining system of type 1 metal profiles, applied to the manufacture and assembly of removable and reconfigurable metal structures, by using standard steel profiles. BACKGROUND OF THE INVENTION
    At present, practically all the unions used in the manufacture of metal structures with standard steel profiles, use the welding joint or the classic screw connections.
    In the first case, the welded joints have the great disadvantage that they are not removable or reconfigurable; its dismantling generally implies its destruction, with the inconvenience that this entails.
    Classic screw connections, on the other hand, need a previous preparation of the profiles to be joined. Operations involving plate welding, stiffening of profile souls, drilling of profiles, etc. are necessary. This type of manufacturing is generally carried out for very specific configurations, so it is only useful for cases that were designed.
    In summary, with the unions currently used in the manufacture of metal structures, welding and bolted joints, there is no possibility of reconfiguring the structure taking advantage of all the components of the system, including the profiles to be joined.
    A removable system for type 1 metal profiles, in which no previous preparation of the profiles is necessary, is the one that uses joining clips. The use of these clips as a mooring of the profiles is frequent in profile joints
    when these intersect, through the use of an intermediate plate drilled to measure, according to the type of profile to use.
    In addition, it must be taken into account that for the unions of the profiles, depending on the design and the method of execution of the union, different types of behavior resulting from the union can be achieved. It can behave as an articulated, rigid or semi-rigid joint, depending on the bending moment it is capable of transmitting.
    With the use of staples, which are shown below, it is sought that the union of different sizes of standard profiles I be possible, more specifically in the case of beam-beam joints flush with the top, without requiring previous preparation operations on the profiles and allowing the joints obtained to be completely removable and reusable. The only operation necessary to perform, using joining systems with fixing clips, washers and standard screws, is the cutting of the profiles to the necessary extent. In addition, with the use of the proposed staple system, an articulated or rigid / semi-rigid knot can be conceived easily and reversibly, depending on the bending moment that is capable of transmitting / absorbing the profiles involved in the joint.
    There are currently disclosures of removable joint systems for standard type 1 steel profiles, such as ES2432915B2. However, when it comes to beams flush at the top, there is no known system that meets the following characteristics: a) that does not require prior preparation of the profiles to be joined, b) that is completely removable and reconfigurable, c) that the same elements used for the union are valid for different sizes of profiles 1, d) that allows to regulate the height exactly to keep the beams flush with the top. DESCRIPTION OF THE INVENTION
    To solve the drawbacks described above, the present invention (Figure 1) consists in the use of a main support plate (1, see Figure 2) and a secondary support plate (2, see Figure 3). Both plates are provided with torn ones (3,4) that make it possible to join different sizes of standard I profiles.
    To make the joining of the profiles, in addition to the main support plate is needed
    (1) And the secondary support plate (2), fixing clips (5, see Figure 1) with their screws (6), nuts (7) and corresponding washers (8). With this system the connection of the beam-beam type flush at the top would be made, using standardized metal profiles of type 1.
    The tears (3) in the main support plate (1) and the tears (4) in the secondary support plate (2), allow the adjustment of the staples and their screws, on both sides of the wing of the different sizes of profiles to join (see Figure 4).
    The main support plate (1, see Figure 2) that is attached to the main beam (9) is provided with side flanges (10) that are welded in the center of the plate by thin sheets (17) and these side flanges they have torn ones (11), which allow to adjust the height for different sizes of metal profiles, when this plate is mounted on the secondary support plate (2) (see Figure 5). This assembly is possible because the secondary support plate (2, see Figure 3) is provided with flanges (13), in which some holes (14) have been made, which allow the use of tightening screws (15), nuts (20) and washers (22), the connection to the main support plate (1) through the tears (11). Other adjusting screws (16), which are placed on the threads (21) of the main support plate (1), allow pushing the tabs (13) of the secondary support plate (2) and, as a consequence, regulate with accuracy the height of the secondary beam (12) with respect to the main beam (9) (see Figure 6).
    When the main beam (9) and the secondary beam (12) are flush with precision from the top, the tightening bolts (15), nuts (20) and washers (22) are tightened (see Figure 6) .
    To avoid torsional stresses in the main beam (9), the forces due to the secondary beam (12) are transmitted through the thin sheets (17) of the main support plate (1, see Figure 2) , which are centered on the core of the main beam (9) (see Figure 5). Because these thin sheets (17) are easily deformable, they allow not to transmit the secondary moments of the secondary beam (12) to the main beam (9), which would involve torsional stresses in the main beam (9).
    For cases where if you want to transmit the bending stresses of the secondary beam (12) to the main beam (9), "The stiffening screws (18) would be placed on the holes (19) of the main support plate (1) (see Figure 6). BRIEF DESCRIPTION OF THE DRAWINGS

PREFERRED EMBODIMENT OF THE INVENTION
    A description of the embodiment of the invention follows, with reference to the numbering adopted in the figures.
    First the main support plate (1) is placed under the main beam (9) and the plate is tied to the wings of the profile using the corresponding clips (5) and its corresponding screws (6), nuts (7) and washers (8 ) (see Figure 7).
    To solve this assembly, a clip (5) is fastened first with its screws (6) and once the size of the corresponding profile wing is adjusted, it is placed under the nut
    (7) flat washer (8) support. All this with care to leave the main support plate (1) aligned with the wings of the profile and bringing the screws (6) of the fixing clips (5) to the edge of the profile to the maximum. This operation is repeated on each tear (3) and once done, firmly tighten all screws (6).
    Next, the adjustment screws (16) are mounted on the main support plate (1).
    Then we place the secondary support plate (2) under the secondary beam (12) and the plate is tied to the wings of the profile following the same operations as in the previous case (see Figure 8).
    The next step is to approach the two beams, with their corresponding plates mounted and when the tears (11) of the main support plate (1) are aligned, with the
    10 holes (14) of the secondary support plate (2) (see Figure 5), the clamping screws (15) are inserted; by the holes (14) and torn (11), but they are left loose to be able to adjust the height with other adjustment screws (16). Once the main beam (9) and the secondary beam (12) are flush accurately from the top, the tightening screws (15) are firmly tightened (see Figure 6).
    15 Then if we want the bending moments of the secondary beam (12) to be transmitted, which is transformed into torsion on the main beam (9), the stiffening screws (18) are introduced on the holes (19) of the support plate main (1) (see Figure 6).
