Definitions

• the objective of the present invention is a junction knot for metal structures, semi-rigid, which allows the connection between beams and pillars, whose main application is the construction of multi-floor car parks, although it can be used for the construction of any other metal structure, or construction that integrates a metal structure.
• This node has a high prefabrication index in that all of its components are manufactured and mounted on site in recessing and screwing operations that allow to improve construction safety and reduce costs and execution and completion times of works.
• Structures are known, especially for scaffolding in which the structure is formed from struts or pillars with which cross beams are related, in which said pillars incorporate rosettes for fixing the beams, while these incorporate at the ends of their there are some fixing forks to the mentioned rosettes, with the existence of homologous windows and lugs in both parts that are coupled together by tongue and groove, making the fixation in the case of scaffolding by means of a pin or latch placed later.
• the invention proposes to solve this question, for which on the one hand it is possible to carry out a quick and effective pre-assembly of the structure and, once it has the appropriate configuration and that all its elements are in the final position, we proceed to the definitive fixation of the knots.
• This fixing is carried out preferentially by means of screws, although it could also be the subject of riveted joints.
• the pre-assembly of the pieces that concur in a knot can only be carried out in a stable position, in which the pieces adopt well-defined geometric positions and therefore do not require subsequent adjustments.
• the interlocking of these is necessarily at right angles, that is perpendicular to the faces of the strut and only this is possible, with a minimum tolerance margin.
• This knot is composed of two differentiated elements of a part a post or pillar that presents at the appropriate height or heights coupling means for the relevant beams, homologous to other means of insertion located in the beams edges, which allows a rapid Initial union of the elements, for a second phase to be fixed by screws, which establish a definitive union.
• This form of assembly is the one that will have the greatest advantages, since all the components in the factory have been assembled and transported on site, the structure will be ready to be assembled, without the need for welding or excessive time. to align the beams and insert the connecting bolts, screw them one by one and give them the necessary tightening torque.
• This node makes it possible to eliminate the previous design stage of the joints and therefore reduce the time necessary for the execution of the joints between beams and pillars of the structure, obtaining better performance during the execution of the work than with a traditional system.
• Another advantage is to improve the process of assembling the structure, with a fast and effective system to make the joint, so that the beam that is intended to rest rests on the knot of the pillar, avoiding keeping it in a centered position while placing the screws to ensure the union, making the assurance by placing bolts that work at cutting, reducing the cost of the installation, not requiring high strength screws and facilitating the realization of the union.
• This structural node is made up of beams and pillars of a certain type of profile for each case, which may adopt different dimensions depending on whether the pillars are for the first floor or for the last, and depending on the span of the beams.
• the joining elements are assembled on the pillar and the vain ends of the beams, composed of two distinct elements that, when joined, form the joint node. These elements are produced in series at the factory's facilities and move ready to be placed on site, being able to form the metal structure of a new multi-storey car park easily and with much faster execution times than conventional ones.
• steel structures are more manageable and less weight, compared to concrete structures prefabricated, so the foundation necessary to anchor the pillars of the first floor of the building may be smaller.
• the pillars that are part of this knot incorporate a pair of rosettes fixed around it, being separated a predetermined distance.
• Each of these rosettes incorporates, at least on each of the faces on which a transverse beam, a polygonal window and at least one circular orifice are fixed.
• each of the beams that concur in one of these nodes has a fork in "C”, fixed in each of the edges of these beams, whose wings are separated from each other a distance equivalent to that separating the existing rosettes on the pillars
• Each of the wings has a polygonal shaped stud, which protrudes from the underside, which has an equivalent configuration of the window of the rosettes and also at least one trade corresponding to that of said rosettes.
• a "C" fork of any beam fits into a pair of rosettes of any pillar, introducing and attaching the lugs of that in the existing windows in these; in such a way that there is no lateral displacement of the beam and the simple coupling between lugs and advantages allows the stable formation of the structure. Subsequently, once the structure of a plant is assembled, for example, it is immobilized by means of screws that pass through the holes in the rosettes and forks to establish the definitive union between them.
• a variant embodiment of this node is provided for those assemblies that require the union between two intersecting beams, linking the ends of one of them at an intermediate point of the other; in this case, at the intermediate point of the beam and on the sides of it there is a pair of rosettes set at different heights, separated by a predetermined distance.
• Each of these rosettes incorporates, at least on each face in which a transverse beam, a polygonal window and at least one circular hole are fixed.
• This rosette perfectly emulates the one placed on the pillars allowing the fixation of a second transverse beam on it, which is the carrier of the knot-forming rosettes, provided that it incorporates a "C" fork as described above.
• the configuration chosen for the existing windows in the rosettes and for the existing lugs in the forks is respectively a rectangular hollow and section, since the polygonal is the simplest and least subject to headings or lateral movements of the beams, forming the joints square, or with the angle that mark these windows placed in the rosette fixed on the pillar or on the auxiliary beam.
• the holes in the rosettes and in each "C" fork are preferably two and are located respectively on the sides of the window and the lugs respectively of the rosettes and fork, engaging each other in the assembly and remaining in position. facing to place a security screw.
• Figure 1 shows a perspective view of a knot in which a pillar (1) and three beams (2) concur before engaging with each other.
• Figure 2 represents a plan and section view along line A-A of a pillar (1).
• Figure 3 represents an elevation and sectional view along the line A-A of a beam (2).
• Figures 4 and 5 show the node of Figure 1, once formed and once secured by screws (6) respectively.
• Figure 7 shows a perspective view of a joint node in this case between a main beam (2b) and two cross beams (2a-2c).
• Figures 8 and 8 show the node of Figure 7, once formed and once secured by screws (6) respectively.
• the node of the invention resolves, on the one hand, the connection between a pillar (1) and a series of beams (2), or also between several beams 2, in both cases forming a quick assembly knot and stable, capable of being immobilized afterwards or secured by screws (6).
• Figure 1 shows the essential elements for the formation of this knot. These are two rosettes (3), fixed perimeter in the pillar (1), which are fixed in parallel position, separated a preset distance, and a fork in "C” (4), fixed in the edge of the beams ( 2), which has between its wings a distance equivalent to the separation between the rosettes (3).
• the rosettes (3) are welded on the pillar (1) in the factory itself.
• the body of the rosette is flat, of polygonal or circular configuration, to which sections of the conforming profile of the pillar (1) are welded on both sides until forming a pillar of the desired height, which incorporates the rosettes (3) in the right position.
• each rosette (3) has an elongated window (31) and at least one hole (32). In figure 2 this window is rectangular and is escorted by two side holes (32).
• the "C” hairpin ends (4) have two parallel wings that are separated by a standard distance equivalent to the separation of the rosettes (3). Each of these wings has a protruding pin down, with a configuration equivalent to the windows (31) and two holes (42) in correspondence with the holes (32) of the rosettes (3).
• a pass-through (2b) that receives in an intermediate zone the confluence of another or other cross-sections (2a-2b).
• the rosettes (5) similar to the rosettes (3) intended to be fixed on the pillars (1), are fixed on the sides of a beam (2b) and have a window (51) and holes (52) ) equivalent to those in rosettes (3) in terms of arrangement and configuration.
• the assembly is easily seen by observing figures 1, 5 and 6 in the case of a knot between pillar and beam and in figures 7, 8 and 9 in the event that the junction knot is made between two beams.
