    DESCRIPTION
    Head for beams meetings
    The present invention refers to formwork systems that include a series of main formwork beams (called belt carriers, main beams or simply beams) supported on struts, usually through heads. More specifically, the present invention refers to a head that allows meetings between beams forming any angle.
    The main formwork beams rest on the struts and serve as support for the secondary formwork beams that support the formwork boards.
    More specifically, the present invention refers to a head that allows joining said beams according to multiple configurations.
    A problem associated with the heads for beams meetings is that the placement of the encounters is difficult and expensive over time. Likewise, the precise placement of the meeting requires a high degree of expertise from the operators.
    It is an objective of the present invention to provide a strut head for formwork systems that does not have the aforementioned drawbacks.
    In accordance with the present invention this is achieved with a head that is attached to a first beam and which has means for receiving the strut on which a second beam will rest. The union between strut and head is carried out by means of two oblique arms between them and that are preferably arranged in such a way that they leave a space between them that allows the entry of the strut when it is inclined with respect to the vertical, but that leaves a space between if lower in a horizontal direction. An advantage of the union using arms is that it allows for easy placement. There are numerous configurations of the oblique arms that meet the specified condition and the person skilled in the art will be able to choose the one that he considers most appropriate depending on other requirements. The present application discloses provisions in this regard that are especially advantageous.
    What is achieved through this configuration is an ease of placement (inclining the strut) and that the strut remains in the joint without the need for additional joining elements. Indeed, gravity causes the strut to remain essentially vertical, and this prevents the strut from leaving the head itself, since the distance in the horizontal direction between arms is chosen in a design smaller than the diameter of the strut.
    Another advantage of the head object of the present invention is that when the union is made by two arms, it is possible to place the strut at different heights, allowing encounters at the same height and crossings between beams at different heights. In this regard, the arms can be shaped as a seat for a top wall of a head. The space for the strut inside the head can also be defined by other elements such as plates, etc.
    Another advantage of the present invention is that the head object of the present invention is installed by placing, the

    first, the head on a beam, then placing the strut on the head and finally the second beam on the strut. It is not necessary to pre-assemble assemblies and assemble elements joined together.
    According to another advantageous aspect that the invention discloses, the head can have a hanger element for joining a beam. This allows easy placement and adjustment.
    The present invention discloses the combination of a basic head structure of known type with the use of plates with housings for the formwork beam terminals. The result is an economical and durable head but that allows multiple formwork configurations without the need for other types of heads or joining parts.
    Another advantage of the structure of the present invention is that metal rods can be used to configure the arms. Advantageously, the head can comprise a rod that forms the arms and whose central part is formed as a means of joining the first beam (for example by means of a hanger element that allows the head to be fixed to a beam by placing the head on top of it).
    More specifically, the present invention discloses a head for beams encounters of the type comprising means for fixing to a first beam, characterized in that it also comprises a reception area of a strut comprising two oblique arms, leaving said arms between them a lateral space for placing a strut in a space for strut defined by both arms.
    Preferably, said arms are arranged in such a way that the lateral space has a distance between arms according to an oblique direction with respect to the horizontal greater than the shortest distance that both arms have according to a horizontal direction, in order to allow a strut to be able to enter the strut space by tilting said strut with respect to the vertical, but cannot cross said lateral space if the strut is arranged vertically.
    Advantageously, one of the arms is arranged horizontally, while the other arm is arranged obliquely with respect to the horizontal plane, forming an angle less than 90 ° and greater than 0 ° with respect to this.
    Preferably said angle is less than 45 °, and more preferably equal to or less than 30 °. Likewise, preferably said angle is equal to or greater than 5 °.
    In a spatially advantageous embodiment, one of the two arms is arranged horizontally, that is, parallel to the first beam, and the other arm is arranged in a vertical plane.
    It is also possible that none of the arms is arranged horizontally, which would cause the corresponding relocation of the other arm to comply with the condition established by the present invention.
    Preferably, the arms have seating areas for a strut wall.
    In a preferred embodiment, the head further comprises a plate that collaborates with the arms in defining said space. Preferably said plate also comprises holes for fixing to said beam.

    Preferably, the means for fixing to a beam comprise a hanger element for hanging the head of a beam.
    Advantageously, the head comprises a metal rod whose ends constitute said arms.
    More preferably, the metal rod has a section between ends that forms said hanger element.

    Figures 2 to 5 show an embodiment of the head object of the present invention.
    The example shown in the figures is formed by a bent metal rod and a sheet -4- equally bent. The metal rod has a first zone -1- that forms a hanger element that allows the head to hang from a horizontal beam, a second zone -2- with two arms to receive a strut and a third zone -3- that connects the first zone -1- with the second zone -2-, defining the lowest point of placement of the strut with respect to the beam from which the device is hung.
    The first zone -1-, which constitutes the hanger element has a symmetrical structure and is formed by two elbows -11-, -12- that give way to two rod sections -13-, -14- designed to cross the spine of a beam and subsequently two double elbows -15-, -16-, -17-, -18- that are joined by a crossbar -19- and whose purpose is to fall vertically on one side of the beam, in order to stabilize the Union.
    The third zone -3- is intended to connect the hanger element with the area in which the arms are located, and in the case shown it is formed by two parallel rod sections -31-, -32-. Different lengths of the third zone -3- define a placement at different minimum height from the top of the strut.
    The second zone -2- is defined by two arms -21 -, -22- each consisting of an end -211 -, -221 - of the rod, and a straight section -213-, -223- and an elbow - 212-, -222- that define the spatial placement of the ends -211-, -221-.
    The head also includes a sheet -4- which is optional. Its function is to assist both in fixing the head to the beam and in the posterior placement of the strut. In particular, the sheet of the example is bent, defining two plates. The first plate -43- is arranged horizontally and defines a profile -44- which, together with the arms -21-, -22- defines the space for the strut. The second plate -41- is arranged vertically and, in this case, it has holes -411 -, -412- to, optionally, screw the head to the beam. The second plate -41- additionally has another fold that defines an area -42- with recesses that receive the rod sections -31-, -32- of the second zone, dimensionally stabilizing the head.
    As can be seen in the figures, the arms -21-, -22-, and more particularly the ends -221-, -222- are oblique to each other. In the case shown, they do not touch each other. The arms -21-, -22- define a space to receive a strut -200-. Likewise, the arms -21-, -22- leave a space such that they allow the introduction of a strut -200- in the space destined to the strut by tilting the strut -200- a certain angle -a- with respect to the vertical (see figure 6), when the head is placed on a beam -100-, with the first zone -1- on the top -101- of the beam. In the example of figure 6, it can be seen how the plate -41- rests on the lower part -102- of the beam (generally, this lower part -102- is made of wood, which allows the head to be screwed to the beam -100- through the sheet -4-).
    The strut, however, is fixed without the possibility of exiting because the gap left by the arms between them has a horizontal distance -di- less than the distance -dp- of the hole, which corresponds to the diameter of the strut -200-. This can be achieved with different arm configurations. In the example shown, one of the arms -21- is arranged horizontally, while the other arm -22- is arranged forming a
    acute angle with respect to the horizontal plane, not being perpendicular to it. Thus, by forming the other arm -22- an angle -a- with respect to the vertical, the distance between arms can be equal to or greater than the diameter of the strut, allowing the entry of the strut when said angle is inclined with respect to the vertical, but it is smaller in the horizontal direction, making it impossible to exit from the side of the entrance when the strut is arranged vertically. Gravity makes the position of the strut -200- store vertically, so the fixation is stable.
    Once the strut -200- is inserted into the head as indicated in figure 6, the strut is placed vertically (see figure 7) and can be lowered to its defined position. The lowest position of the strut that allows the head 10 is defined by the interference of the upper wall -201- of the strut -200- with one or both arms of the head. However, the head allows the upper wall -201- to be in a higher position, if required.
    Once the strut -200- is placed, another beam -150- can be placed on it using a corresponding accessory -20215, of known type, as seen in figures 9 and 10. As can be seen, the encounter between beams - 100-, -150- obtained in this way can be done following any angle. It would also be possible for the beams to cross, for which it will be necessary to arrange the higher wall -201- with respect to the head, which will allow the beam -150- placed on the strut -200- to cross the other beam -101 - above.
    20 Although the invention has been presented and described with reference to embodiments thereof, it will be understood that these are not limiting of the invention, so that multiple constructive or other details that could be evident to the technicians of the sector could later be variable. of interpreting the subject matter disclosed in the present description, claims and drawings.
