Definitions

  • the invention relates to a dynamic and progressive lifting anchor, a concrete building element, particularly thin such as a slab thin or ribbed, pipe, thin panel poured horizontally or vertically, vault or any other element having to use this type of anchor.
  • lifting anchors for known thin slabs such as the flat-footed anchor of the figure 8a , or the plate anchor of the figure 9a require, when they are put in place before pouring concrete, to be coupled to four armatures or metal bars 1-4 arranged in pairs, the first pair of bars 1, 2 being disposed on either side of the flat surface of the anchor considered in its width, the second pair of bars being disposed on either side of the flat part of the anchor considered in its thickness, the flat feet of the anchor or the tray being arranged under the bars.
  • Each pair of bars must be ligated at both ends.
  • This installation requires different handling operations, and various controls to ensure the proper placement of the anchor, bars and ligatures and generates time and cost.
  • these flat-footed anchors can only define a single configuration, a unique use with the bars and a single lifting force.
  • the document EP 2075392 describes a lifting tool for lifting a prefabricated floor element.
  • This lifting tool comprises a vertical section (10), which has at least one application point (11) capable of being hooked to a lifting device, and a transverse portion (17) extending in the transverse direction.
  • the vertical section further comprises a receiving means (12), with a lower space for receiving a wire. This receiving means is located between the vertical section and the transverse section.
  • the invention aims to overcome these disadvantages.
  • the invention proposes a simple and satisfactory solution to provide a lifting anchor suitable for thin construction elements (a slab for example), limiting the handling required for its implementation and to define multiple configurations and multiple forces of lifting.
  • the invention relates to a lifting anchor of a modular building element, comprising at least one assemblable unit obtained by folding a flat, defining a flat head portion capable of being attached to a machine gripping, and a flat foot part diverging from the head outside the main plane defined by the head.
  • the assemblable unit comprises a flattening junction portion interposed between the head and the foot, the flat part of which can be straight or forming a recess able to accommodate a bar, arranged under the plane defined by the foot of the unit, this flat being provided with at least one cutout defining a retaining lug of the bar located opposite the recess to partially close it.
  • the anchor according to the invention comprises a head part 6, and a part 7 forming the foot.
  • the anchor with the exception of the head 6 which remains outside the material of the construction element and is adapted to be attached to a handling machine, is intended to be embedded in the constituent material of the construction element whose anchor is intended to facilitate handling.
  • This anchor has been particularly designed for the handling of thin slabs and its head is accessible from a free surface of the slab in which has been practiced a recess or "reservation" authorizing the passing of the head 6 of the anchor, then that the foot 7 of the anchor are immersed in the concrete.
  • the anchor according to the invention is formed of at least one assemblable unit 8 obtained by folding a flat, defining a flat head portion 9 having a passage hole 11 of a gripper, and a flat foot portion 12 diverge relative to the head 9 outside the main plane defined by the head of the unit.
  • the assemblable unit 8 comprises a junction portion 13 which is more visible on the figure 2 , which extends in the extension of the head of the unit and gives birth to the foot of the unit, to form a recess arranged in the plane defined by the foot 12 of the unit.
  • the recess 13 has a C-shaped cross-section in order to accommodate a bar with a cylindrical profile but may have any other shape that can serve as a reception housing for the bar or reinforcement.
  • the foot 12 of the unit comprises a retaining pin 14 (visible in section on the Figures 6a and 6b ) located opposite the recess to close it partially (see Figures 6a and 6b ) and which is advantageously obtained by a portion of flat lying in the extension of the plane of the foot 12 while the adjacent side portions 15 of the flat are folded under this plane to form the recess 13.
  • the bar 16 is introduced by one side of the unit 8 into the recess 13 and passes under the retaining pin 14.
  • the figure 3 represents an alternative embodiment of the retaining lug of the bar in the recess according to which two lateral lugs 17 are provided per assemblable unit and it is the flat portion interposed between these two lateral lugs which is folded under the plane defined by the foot 12 of the assemblable unit to define the recess.
  • the anchor comprises two assemblable units 8 paired with each other being positioned with their heads 9 contiguous to each other by their large face and their feet 12 diverging externally.
  • twin units 8 are joined to each other by a folded flat portion 18 coinciding with a side edge of the head of a unit.
  • figure 4 shows variants of embodiment of the anchor according to the invention according to which this anchor is composed of a single autonomous assembly unit with central pin 14 ( Figures 4a and 4c ), with lateral pins 17 ( figure 4b ) with a wider foot 19 than the head part and the joining part (which are of the same width).
  • This autonomous unit 8 can be used alone or in combination with another identical or different (in thickness or arrangement of lug or inclination of the foot). When two autonomous units are used, they can be secured to one another by rivets or welding.
  • the figure 5 represents a variant embodiment of the anchor of the figure 1 with assemblable units secured by a flattened bridge, according to which the heads of the twinned units are provided with two additional orifices 21 for passing additional stiffening bars 22 (but not mandatory) passing through the heads in their thickness. There is illustrated the presence of a single additional stiffening bar 22 passing through one of the orifices.
  • the figure 6 represents a variant embodiment of the anchor of the figure 1 without stiffening bar, but with a reinforcing plate 23, and an internal reinforcement 24.
  • the reinforcement 24 is also derived from the folding of a flat part defining a head portion 26 provided with a through hole 27 corresponding to those of the two assemblable units 8, and two opposing half-feet 28 each extending one side of the head 26 being separated by a cutout coinciding with a median plane for the head 26.
  • each half-foot 28 partly follows the underside of the foot of the corresponding unit.
  • Each half-foot 28 has a general complementary shape of the foot and the joining portion of the unit that can be assembled below it.
  • the reinforcement further comprises a lateral locking pin 29 between the two twin units.
  • the feet 12 of the assemblable units of the anchor comprise at their ends each a curved rim 31 for locking the corresponding half-foot of the reinforcement.
  • This assembly with assemblable units and central reinforcement can be completed by the insert plate 23 which will be mounted by sliding of its central base 32 provided with a window 33 for passing the contiguous heads assembled assemblable units until application of its two facets diverging sides 34 respectively along the upper faces of the feet 12 of the two twinned units
  • the internal reinforcement has a smaller thickness than the platen or assembled units of the anchor while in the example of the figure 6b the plate, the reinforcement and the assembled units have the same thickness, thus showing the numerous possible embodiments.
  • the figure 7 represents various configurations that can be realized with the anchor according to the invention, allowing by a simple assembly of assemblable elements (units 8, reinforcement 24, plate 23, bar 16, 22), to define 8 lifting forces between 2 and 17 kN, knowing that a unit used alone 8 makes it possible to define a lifting force of 1 kN, and that there remains the possibility of coupling one or the other of the represented assemblies, with the additional stiffening bars 22 of the figure 5 . So still many possibilities for defining lifting forces.
  • these flats In order to allow their folding along the fold lines A-D, these flats have a thickness generally less than 15 mm, preferably a thickness of 2, 3, 4 or 5 mm.
  • the reinforcement may be attached to the two flats by rivets at the head of the anchor and / or the body of the anchor or by folding the top and bottom ends of the anchor.
  • the anchor according to the invention has major advantages over anchors of the state of the art with the possibility of removing a pair of stiffening bars and the Prior art ligatures and definition of a multitude of lifting forces by assembling simple fabrication elements.
  • An anchor of this type is made by a simple and inexpensive manufacturing process, based on the folding of a single or two flattened (s) optionally reinforced (associated with a reinforcement) allows for the lifting of thin slabs but more heavy.
