Definitions

  • the present invention relates to a construction element, in the form of a profile, comprising two or more strips joined by longitudinal unions. Said strips can be formed in different shapes to allow the creation of profiles of various sections, with a considerable saving of material and improving its properties.
  • the construction element of the invention is applicable, for example, in forming the frame for partitions and claddings using prefabricated panels.
  • the profiles obtained with the mentioned systems have a rigid section, which favors the transmission of vibrations between the elements mounted on either side of the profile. This problem is particularly important when the construction element is used in the formation of frames for walls with prefabricated panels.
  • the present invention relates to a construction element, consisting of a profile comprising at least two strips that are joined together by means of at least a longitudinal union.
  • At least one of these strips has one or two crenellated longitudinal edges with alternating projections and recesses.
  • Each longitudinal union between strips is made between projections of at least one crenellated longitudinal edge of one strip and at least one stripe for longitudinal union belonging to other strip.
  • the number of strips having one or two crenellated longitudinal edges is less than or equal to the number of strips which have at least one stripe for longitudinal union.
  • the stripe or stripes for longitudinal union may be located along the longitudinal central zone of the strip to which they belong.
  • stripe or stripes for longitudinal union may be limited by a non-crenellated longitudinal edge.
  • the longitudinal union between strips is made between projections of a crenellated longitudinal edge of one first strip and at least two stripes for longitudinal union, belonging to a second strip, separated transversely to each other.
  • said projections can have opposite transversal slopes.
  • the union could also be made between projections of crenellated longitudinal edges of a first strip with two crenellated longitudinal edges and at least one stripe for longitudinal union, belonging to a second strip.
  • both the strips and the projections of the crenellated longitudinal edges may have reinforcing protrusions.
  • the construction element may include at least one strip having at least one non-crenellated longitudinal edge finished as a toothed edge.
  • the construction element may be composed of only two strips, one of which presents a crenellated longitudinal edge and is joined longitudinally, by the outer end of the projections from its crenellated longitudinal edge, to a stripe for longitudinal union belonging to one of the surfaces of a strip without crenellated longitudinal edges. Construction elements with sections of different shapes can be achieved depending on the shape of each strip.
  • One of the strips that form the construction element may have two longitudinal edges crenellated, and join, by the outer end of the projections on either longitudinal edge, to two strips without crenellated longitudinal edges. In this way, I-shaped, C shaped, Z shaped, omega, etc. profiles can be achieved.
  • each crenellated longitudinal edge can make contact, with the surface of the strip to which are joined, along a single stripe for longitudinal union or along more stripes for longitudinal union, separated transversely to each other.
  • the projections can have different slopes, for example alternately opposite transversal slopes, enabling the section of the construction element to be not completely rigid, but having a certain capacity for transverse deformation, which also spreads along the construction element, providing a spring effect which will reduce or dampen vibration transmission across the profile and between the panels or elements fixed to said strips.
  • the strips in the construction element may have deformations which may run along the strip and / or on the projections of the crenellated longitudinal edges.
  • the join between the outer end of the projections and the stripe for longitudinal union of the strip can be made by welding, soldering, sewing or stitching, clinching, folding, bending, pressure, clipping, gluing, riveting, etc.
  • All the projections of one or both crenellated longitudinal edges, belonging to one strip may be of equal size. Also, the projections of one or both crenellated longitudinal edges, belonging to one strip, may be of different size.
  • the strips with one or two crenellated longitudinal edges can be obtained from a band of greater width, through one or more longitudinal cuts, of sinuous path, with straight or curved sections, in order to obtain two or more strips with crenellated longitudinal edges.
  • this cutting system it is possible to obtain strips with one or two crenellated longitudinal edges.
  • Figures 1 to 3 show a profile (1) formed according to the invention, which is composed of two strips (6, 8), joined together by a longitudinal union.
  • the projections (9) of the strip (7) will form tabs (12) which can pass through the strip (8) and join onto a stripe for longitudinal union (3).
  • Connections to said strips can be made by welding, soldering, sewing or stitching, clinching, folding, bending, pressure, clipping, gluing, riveting, etc.
  • the construction element of figure 5 is obtained from flat strips, similarly to that described with reference to Figures 1 to 4 .
  • the outer ends (11) of consecutive projections (9) are oriented alternately in opposite directions but are located in the same plane.
  • projections (9) may have different slopes, for example alternately opposite transversal slopes with respect to the longitudinal central zone (29) of said strip (7).
  • Said projections (9) are located in two different planes and are joined to two stripes for longitudinal union (3), separated transversely to each other, belonging to the same strip (8)
  • each crenellated longitudinal edge (4) has alternately opposite transversal slopes with respect to the longitudinal central zone (29) of said strip (7).
  • the projections (9) of each crenellated longitudinal edge (4) are located in two planes (23', 23"), Figure 7 , and make contact on two stripes for longitudinal union (3), which are separated transversely to each other, belonging to the same strip (8)
  • the union between the outer ends (11) of the projections (9) and the stripes for longitudinal union (3), either located on the surface of the strips or on the surface of the lateral folds (21), can be made by soldering, riveting, clinching, clipping, bending and pressure, etc.
  • the strips with two crenellated longitudinal edges (7) take the same configuration as the central strip (7) of Figure 8 , with the projections (9) of the two crenellated longitudinal edges of each strip (7) in a same plane and making contact along the same side of the lateral folds (21) of the strips (8).
  • the projections (9) can adopt the same arrangement, with alternately opposite transversal slope, described with reference to Figures 9 and 10 .
  • Figures 12 and 13 show another construction element in the form of a profile (1) with Z-shape, also composed of three strips.
  • the central strip having alternate projections (9) and recesses (10).
  • Said projections (9), of each crenellated longitudinal edge (4) have alternately opposite transversal slopes with respect to the longitudinal central zone (29) of said strip (7).
  • the outer ends (11) of the projections (9), belonging to one crenellated longitudinal edge (4) make contact alternately by opposite surfaces of the lateral fold (21) of the strips (8).
  • the surfaces of the lateral fold (21) define the two stripes for longitudinal union (3).
  • Figure 13 shows how the projections (9) of each crenellated longitudinal edge (4) are located in two planes (23 ', 23") with opposite transversal slopes.
  • FIG 18 a construction element, similar to the construction element of figure 17 , composed of a strip with two crenellated longitudinal edges (7) and a strip without crenellated longitudinal edges (8).
  • the projections (9) are sloped with respect to the lateral zone (30).
  • the projections of each crenellated longitudinal edge (4) have opposite slopes, converging together, and are joined to the strip (8) along to contiguous stripes for longitudinal union (3), belonging to said strip (8).
  • the outer end (11) of the projections (9) of the two crenellated longitudinal edges of the strip (7) may join the strip (8) on one stripe for longitudinal union (3).
  • the projections (9) may have opposite slopes divergent, joining the outer ends (11), of the projections of the two crenellated longitudinal edges, on to parallel stripes for longitudinal union (3).
  • the number of strips having one or two crenellated longitudinal edges is less than or equal to the number of strips which have at least a stripe for longitudinal union.
  • Figures 23 to 25 represent the same construction element (1) under load.
  • both the projections (9) and the longitudinal central zone (29) of the strip are deformed, with a slight curvature, reducing the distance H between the external strips (8).
  • the longitudinal central zone (29) of the central strip (7) adopts, along said strip, a slightly sinuous path as shown in section in Figure 25 .
  • a spring effect is achieved, which reduces the transmission of vibrations between external strips (8), improving their mechanical and acoustic behavior against impact, pressure or seismic actions.
  • said central strip (7) or web (19) may be of a different length to the length of the external strips (8) or flanges (20) of the profile (1).
  • said central strip (7) or web (19) can be pre-stressed, being stretched or tensed during the joining process between strips.
  • profiles are made by roll-forming. By this technique, deep reinforcements are difficult to make due to the stresses and strains that are created around such reinforcing reinforcements. These stresses may modify in any cases the geometry of the profile.
  • the reinforcing deformations can be made pronounced, without affecting, as they are in different strips, the geometry of the profile.
  • the union between the outer end (11) of the projections (9) and the stripe for longitudinal union (3) can be made by welding, clinching, riveting, clipping, bending, pressure and folding, etc.
  • the projections (9) belonging to the same strip may have different sizes, in only one crenellated longitudinal edge (4) or in opposite crenellated longitudinal edges (4) of the same strip.
