Definitions

  • the system is significantly based on or supported by a metal "I"-beam of those integrated by the connection of a double "C"-shaped section profile having bent flanges connected or overlapped by their respective webs, facing one another and separated by spaced and equidistant transverse welded anchor pins.
  • Beams in combination with a series of accessories, complying with several structuring, reinforcing, shoring, scaffolding functions, and for other purposes in any type of public or private work or construction processes, consisting of a metal beam manufactured in a sheet galvanized or treated against oxidation due to its broadest use being exposed to the elements, beams which must preferably have great resistance to stresses in any working sense and to the loads they must support, and which, preferably, are more recommendable the lighter and less heavy they are.
  • Said beams are doubly lightened in the web of each side and in absolute transverse coincidence of their housings. In short, it is the same reverse profile facing at their webs and connected by welded transverse brackets.
  • Both systems are constituted of "I"-beams formed by two "C”-shaped profiles having bent flanges, connected at their respective webs by means of transverse anchor pins.
  • the first beams have diamond-shaped openworks having rounded edges in their webs with a very short equidistance and broad span, having intercalated ribs in the form of a cross, which are ribs parallel to the sides of each openwork, and which in the center of these are provided with one or two boreholes, depending on the section, in this case aligned according to the vertical axis.
  • the second ones have circular-shaped aligned openworks, having a somewhat smaller span with regard to the section, which is approximately 40%, and provided with circumscribed boreholes arranged in orthogonal formation with regard to the central openwork.
  • the web is provided with reinforcements in the area affected by the openwork and by the boreholes. This borehole arrangement is made on the first two end openworks and on every third openwork on the rest of the beam.
  • the section of the beams is invariable in the first and second case.
  • connectors are used which are provided with a maximum of eight connection ways, a circumstance making it unfeasible to bend the reinforced horizontal axis of the frame which, logically, has certain resistance conditions.
  • the invention tries to rationalize and use the working moments of said beams in order to adapt them such that, combined with one another, it is not necessary to use beams having an excess dimension in relation to the stresses they must carry out or the loads they must support; therefore, two beams have been provided having different sections but which are directly complementary for being able to be combined or joined together using practically ambivalent means and parts; very simple and lightened beams which, according to the calculation carried out, effectively comply with the working task they must carry out.
  • the new development provided by the beam of the invention in its two versions, is defined by a series of strategically arranged lightening holes for coupling a group of additional complements, converting it into the only beam known which, with dimensions and thicknesses smaller than those existing, much better defines its resistant capabilities since the lightening holes are understood as exclusively functional and not mainly aesthetic or commercial.
  • the object of the invention since it is a prefabricated metal beam, allows being used in any sector needing structural solutions of any type, no matter how complex they are, not necessarily having to manufacture said frames for exclusive use on that job.
  • the beam having a smaller section shares the same lightening holes of equal size (60 mm) as the beam having the larger section, even though it has a smaller section as mentioned, and with regard to thicknesses, its second order application being a very versatile and resistant purlin which, since it shares the same distances between axes on beam beginning and end plates as those which the beam having a larger section has, can be perfectly combined with one another and accessories can be exchanged which, in this case, become common to the two beams.
  • the invention consists of the development of light, hollow "I"-beams made up of two "C"-shaped profiles 3 mm thick, having bent flanges, separated by corresponding spaced transverse anchor pins, having flat webs and in two versions having a different section, the smallest one, which is called purlin, being 19% smaller, and the bases of the beam having the larger section, which is called main beam, are equal to those of the beam having the smaller section, or purlin, and to the measurements of the base of the latter, such that the additional beginning and end cover plates of the beams have a different set up but equal distribution of the lightening holes and anchoring or fixing holes.
  • Both beams, the main beam and the purlin also have the same developments and equivalent distribution and sizes in the lightening hole means and in the complementary anchoring and fixing means.
  • the lightening holes are circular transverse openworks equal in both beams, 60 mm in diameter
  • the anchoring through holes are also equal in both beams, 18 mm in diameter, considering that the distribution of lightening and anchoring and fixing holes is formed by pairs equally spaced between centers at an equal distance, 150 mm, intercalating between each pair a single lightening hole in the beams having a longer length, 2000 mm upwards, having a set of four circumscribed holes distributed in an orthogonal position on the beam having a larger section for each openwork, and a set of two holes aligned with the longitudinal axis of each openwork on the beam of a smaller section or purlin.
  • said cover plates have a rectangular shape adapted to the section of the main beam, and they have a square shape for the purlin, but the width of these plates is equal and coincides with the section of the bases of each one, and the distribution of the lightening holes and fixing boreholes is the same, one being equally centered having a larger diameter and four others orthogonally circumscribing the former, with an equal distance between centers (110 mm) in both cases and different but proportional thicknesses of 8 mm for the main beam plate and 6 mm for the purlin plate.
  • the main beam and the purlin are arranged in said beams in five lengths comprised between 2500 mm and 500 mm, with differences of multiples of 500 mm between them. Furthermore, these beams contemplate a beam equivalent to 22% of the latter, which is a part for compensating sizes when double connectors are alternated with single connectors in the same frame.
  • said connectors a necessary element for carrying out any frame, are defined by six plates in a hexahedral arrangement in the case of single connectors with six connection ways, and in the case of double connectors, they are defined by six plates in a parallelepipedic arrangement with ten connection ways for the beams, forming two equivalent bodies connected to two single connectors in which the base plates contain larger diameter lightening holes and smaller diameter lightening holes equally spaced and in an equal arrangement as those of the cover plates and those of the beams themselves, and smaller diameter lightening holes in the elevations with an arrangement equal to the previous ones.
  • connectors which, for better rationalization of the assembly operations and for ensuring greater resistance, internally incorporate on the smaller diameter lightening holes respective locknuts for locking the different coupling elements of the corresponding beams. Nuts allowing the direct screwing in of the coupling elements by turning them in one direction or another, according to their position, to ensure tightening.
  • the invention is also provided with an adjustable jack made up of a corresponding spindle assembled in a support formed by a threaded cylinder resting on a rectangular plate with fixing boreholes and triangular reinforcement buttresses for reinforcing the cylinder, and one end with an anchoring hole for bracing it to the beams.
  • An anchoring which, by means of a corresponding pin, threading and complementary side means, is assembled in the larger diameter lightening holes of the beams.
  • a spindle threaded to the left on one end and to the right on the other end allows installing the beam, opening or closing the diagonal by simply turning said beam.
  • Another complementary means is also used for fixing a rod to the beam which is adjusted against the internal diameter of two parallel, larger diameter lighting holes, and is fastened by means of respective nuts above and below the wedge.
  • this jack is completed with a diagonal reinforcement for the rod and a diagonal reinforcement for the jack.
  • the first one is a part in the form of a semi-cylindrical, semi-ball joint with a perpendicular openwork and milled sides on its perimeters, and the other one is a disk-shaped part with a central concentric recess and a circular borehole equally concentric to the recess.
  • the first one is arranged between two parallel larger diameter lightening holes with the milled sides locked against their edges and fastened by means of nuts, one above and one below the wedge.
  • the second one is arranged in said lightening holes, one on each side, serving to fasten the pin and nuts going through the jack anchoring hole.
  • the main beam is generally indicated with (1) and the purlin beam with (1a), which are provided in their respective webs with larger diameter through lightening holes which are paired (5) and intercalated (6), of which holes, each one is surrounded by smaller lightening holes (7) in a preferred orthogonal arrangement, since the section of said main beam allows this, and smaller lightening holes (7a) aligned with the longitudinal axis of the lightening holes (5), since the section of the beam (1a) is smaller.
  • the distance between axes of the lightening holes (5) is (c) in all cases, that the distance between the axes of the smaller lightening holes (7) or (7a) is also (c) in all cases; that the distance between the end of the beam (1) and (1a) and the axis of the lightening hole (5) is (d) in all cases, and that the distance between the axis of the lightening holes (7) and (7a) is (e) in all cases.
  • Said main (1) and purlin (1a) beams having a hollow web (2) are formed by respective profiles (2a) and (2b) having bent flanges and separated by spaced anchor pins (3).
  • the beams (1) and (1a) are covered at their ends by means of the corresponding plates (8) and (9), see figures 3 and 4, and figures 5 and 6.
  • Said plates are provided with equally centered larger diameter lightening holes (5) and with smaller diameter lightening holes (7) in the contour in the same orthogonal distribution as in the beam (1), such that the distance (n) between centers of the lightening holes (7) is the same in the two plates (8 and 9); such that the section (b) is equal in both plates (8 and 9) and equal to the section of the base of the two beams (1) and (1a), which are equal to one another. Therefore, the section (a) of said beams corresponding to the height thereof, and the thickness of the latter, which is 8 mm for plate (8) and 6 mm for plate (9), varies.
  • the connectors in figures 7 to 9 are single connectors integrated by hexahedral volumes (10) which, on all their faces, are provided with smaller lightening holes (7) in an orthogonal distribution with the same distance (n) between axes, just like the plates (8 and 9), and the double connectors in figures 10 to 12 are parallelepipedic volumes (11) comprising two hexahedral volumes (10) and an empty spacing (12) between the elevations.
  • the faces of the elevations and sides have smaller lightening holes (7) in an orthogonal distribution and the same distance (n) between axes.
  • said smaller diameter lightening holes (7) of the single connectors (10) and double connectors (11) are internally provided with nuts (7b) attached thereto and fixed by welding or pressing, such that the coupling elements can be fixed directly to said connectors (10) and (11) by simply turning them in the suitable direction.
  • the adjustable jack (13) of figures 13 and 14 is provided with a spindle (14) finished in an anchoring hole (15); it is screwed into a cylinder (17) arranged in a base plate (18) reinforced by buttresses (19) and provided with smaller lightening holes (7) with the same distance (n) between centers as that of the plates (8 and 9) and connectors (10 and 11).
  • the diagonal reinforcement (20) of the rod of figures 15 to 17 is a semi-circular wedge-shaped part having milled sides (21) defining a central body and the sides, having a central vertical anchoring borehole (22).
  • the diagonal reinforcement (23) of the jack of figures 18 and 19 is a circular part with a central recess (24), a concentric relief (25) and a central openwork (26) with very little thickness.
  • Figures 20 and 21 show the arrangement of said diagonal reinforcements, thus the one corresponding to the rod (27) is assembled in the wedge (20), being fastened or tightened by one nut (28), which can be seen in the part under the wedge, and by another nut which cannot be seen, which is above the wedge.
  • the reinforcement corresponding to the jack (13) can be seen assembled in a through screw (29) fastened by the reinforcements (23), one on each side, going through the anchoring hole (15) of the end of the spindle (14).
