Definitions

  • the present invention refers to an expansion joint particularly designed for concrete works, specifically for obtaining concrete paving in which once the concrete is poured on site, it is necessary to extend it in order to achieve pavement with a smooth surface and at the required height.
  • the joint of the invention is not only usable as an expansion joint but also as a screed bar, as a guide rail for the concrete surface vibrators, as an enclosure panel, as a working joint and as a contraction joint.
  • the object of the invention is to prevent cracks due to straining, to prevent hydraulic and thermal retraction, to absorb the stresses from the concrete, to protect the edges thereof, to prevent the leveling difference of the working joint due to buckling, to prevent the joint from projecting from the concrete level during the curing process, and to increase the possibility of achieving a more planar floor.
  • the expansion joint proposed by the invention is especially suitable for being applied to the first one of the previously mentioned methods since, in theory, it constitutes a screed bar which further acts, as previously stated, as a guide rail for surface vibrators, which can be used as an enclosure panel or as a working joint and which can further make up a contraction and expansion joint.
  • the joint proposed by the invention is formed by means of the functional combination of two pieces basically profiled according to a rectangular triangle, having a suitable length, such as 3 meters for example, with the special particularity that said pieces are coupled by tongue and groove through one of their sides, specifically through their coupling sides corresponding to one of the catheti of its section, one of said pieces having a rectangular grooving while the other one has a complementary outward or male deformation, such that the combination of both pieces in turn generates a new profile, in this case having a basically isosceles triangular section.
  • each of the mentioned pieces incorporates a plastic strip corresponding with its upper edge or vertex, such that in the assembly of both pieces the respective plastic strips make contact with one another and slightly project with respect to the double metallic profile.
  • Both the top lateral side corresponding to the hypotenuse of their section and the bottom face of the two pieces of the joint have many openings for allowing the concrete to enter inside them, which does not occur with their sides that couple together, which are completely closed.
  • the two metal pieces forming the joint are in turn provided with special openings at suitably spaced and sized intervals for the coupling of vertical pins intended for being nailed in the ground and supporting the joint, with the ability to adjust the height for the joint, for which purpose a transverse stud bolt, also arranged on the corresponding piece, collaborates with each vertical pin.
  • the expansion joint proposed by the invention is structured by means of two tubular and metallic profiled pieces (1) and (2), basically having a right triangular section, one of them (1) provided on its side (3) that couples to the other one with a wide rectangular grooving (4), while the other one (2) has an also rectangular outward deformation (5) intended for fitting into the grooving (4) in order to form a tongue and groove coupling, as can be observed in either one of Figures 2 and 4, such that after the coupling between these pieces (1) and (2), the joint as a whole adopts an isosceles triangle profile, for example with a length of 3 meters, a height comprised between 10 and 15 cm, and a width in the order of 12 cm, dimensions mentioned merely as an example, for obtaining a pavement with a standard thickness.
  • the pieces (1) and (2) are provided on their top lateral sides and on their bottom sides with many openings (6) allowing the free passage of the concrete (7) towards the inside and through the joint itself, the inner walls (3) joined between pieces (1) and (2) lacking openings however.
  • a small longitudinal grooving (8) is defined at the top level in each one of these pieces (1) and (2) in correspondence with their also top edge, intended for the coupling of a plastic strip (9) which, together with that of the other part, finishes the joint on the top portion forming the top edge thereof.
  • each one of the pieces (1) and (2) incorporates in points suitably spaced along the length thereof, special openings (10) for the passage of respective vertical pins (11) which, intended for being supported on the ground (12), as can be especially observed in Figure 4, allow adjusting the height of the triangular profile formed by the pieces (1) and (2) and suitably fixing any position chosen for them, with the collaboration of side stud bolts (13) which in turn act in openings (14) of pieces (1) and (2) as nuts.
  • pins (11), having a considerable length, allow an also considerable adjustment of the height for the profile formed by the pieces (1-2), which in turn allows using the latter as a light, self-supporting, fast and easy leveling screed bar that does not require subsequent stripping.
  • the plastic strips (9) arranged on the top edge or border of said bar very considerably facilitate movement of the surface vibrator while at the same time they are capable of supporting it without undergoing deformations.
  • the double profile can also be used as an enclosure panel, that is, as a formwork periphery limiting element, also being light, easy to release, self-supporting and simultaneously acting as a contraction joint, working joint and expansion joint.
  • one of the two pieces (1-2) forming the joint may be used separately.
