Definitions

  • the invention generally relates to anchors for handling panels of hardenable material, especially concrete.
  • this panel may have a small thickness in a first direction relative to its dimensions in a plane perpendicular to this first direction, this anchor comprising an elongated rod in a second direction substantially perpendicular to the first embedded in the panel, a gripping head integral with an outer end of the rod projecting from the panel, and a boss increasing the thickness of the outer end of the panel; the stem in the first direction.
  • Such an anchor can be used to raise a prefabricated concrete panel horizontally.
  • the lifting operation consists in passing this panel from a horizontal position to a vertical position, by applying to the head of the anchor a force oriented initially in the first direction, then progressively oblique with respect to the first and second directions while the panel tilts, and finally in the second direction when the panel is vertical.
  • the anchor can also be used to lift the panel once it is in a vertical position, by applying on the head of the anchor a force in the second direction.
  • the boss of the anchor makes it possible to increase the rigidity of the anchor under the head, and to avoid that it is twisted during the raising. Lateral anchorage increases the pull-out strength of the anchor during lifting, when a force is applied in the first direction on the anchor head, creating a compression zone of the axle concrete in the first direction or slightly inclined relative to the first direction, contributing strongly to this resistance. This is particularly important for panels of small thicknesses in this first direction.
  • a lifting anchor according to the preamble of claims 1 and 4 is described in DE 43 10022 A1 .
  • the object of the present invention is to propose an optimized anchor compared to those of EP-B-0 434 819 , offering even better performance in lifting, lifting and turning.
  • These optimized anchors offer better tear resistance in lifting, and thus allow to raise even thinner and / or heavier panels without cracking concrete. They also make it possible to extend the lift in conditions of increased safety compared with the anchors of the prior art, especially in the presence of biasing forces (angle slings, transverse wind, etc ).
  • the device of the invention is according to one of claims 1 or 4.
  • the anchor may also have one or more of the features claimed in the dependent claims.
  • the anchor is suitable for lifting, lifting and turning panels made of hardenable material, including but not limited to prefabricated concrete panels 10.
  • Such a panel typically has a general shape of rectangular parallelepiped, thin in a first direction XX 'relative to its dimensions in a plane perpendicular to this first direction.
  • This panel 10 is delimited by two large faces 11 opposite perpendicular to the first direction X-X ', and four small faces 12 connecting the two large faces 11, constituting the edge of the panel 10.
  • Two small faces 12 opposite are perpendicular to a second direction Y-Y ', and two other small faces 12 opposite are perpendicular to a third direction ZZ' perpendicular to the second.
  • the second and third directions Y-Y 'and Z-Z' are perpendicular to the first.
  • the two large faces 11 are generally flat but may include various geometric shapes. Although the shapes of the panels to be lifted are generally parallelepipedic, more massive pieces of various shapes may justify the use of this type of anchor.
  • the anchor 2 comprises a rod 20 elongate substantially in the second direction YY ', having a main portion 23 embedded in the panel 10, and an outer portion 21 integral with one end of the main portion 23 and aligned with the this.
  • the outer portion 21 protrudes from the panel 10.
  • the anchor 2 further comprises a gripping head 30 secured to the end of the outer portion 21 opposite the main portion 23, and a boss 40 increasing the thickness of the portion outer 21 of the rod 20 in the first direction.
  • the rod 20 has perpendicularly to the second direction Y-Y 'a strong section, several millimeters in width along the first and third directions.
  • the anchor 2 is of spherical head type, this head being intended to cooperate, both for lifting, lifting and reversing, with a ring 70 of the type described in the documents of FIG. FR-A-1,568,605 , FR-A-2,382,398 and EP-B-0 679 143 .
  • the head 30 has the shape of a solid disc, with an axis extending in the second direction Y-Y ', of diameter greater than the width of the rod at least in the first or third direction.
  • the ring 70 comprises a spherical piece 71 for connection with the head 30 of the anchor, called a nut, and a ring 72 ensuring the connection between the nut 71 and the hoist, called shackle.
  • the nut has an arcuate groove 711 centered on the center of the nut 71 and extending substantially over a quarter circle, open on a radially outer side, in which is engaged the head 30 of the anchor.
  • the groove 711 has a T-section, and comprises a radially inner zone of relatively greater width intended to receive the head 30 of the anchor 2, and a radially outer zone of relatively smaller width intended to receive the outer portion 21 of the stem 20.
  • the width of the inner region of the groove 711 corresponds to the diameter of the head 30, and the width of the outer zone corresponds to the width of the outer portion 21, considered along the third direction Z-Z '.
  • the groove 711 comprises at one end an orifice for introducing the head 30 of the anchor into the groove 711, and has on one side opposite the insertion orifice a blind end, the head occupying during lifting operations and lifting the panel a handling position in which it abuts against this blind end.
  • the outer part 21 of the rod 20 and the head 30 of the anchor 2 are arranged in a hemispherical reserve 13 formed in a small face 12 of the panel 10 perpendicular to the second direction Y-Y ', this reservation 13 having a diameter slightly higher than that of walnut 71.
  • the lifting operation of the panel 10 is carried out first by engaging the nut 71 in the reservation 13, such that the head 30 of the anchor 2 enters the hole of the groove 711.
  • the nut 71 is oriented so that the groove 711 extends in a plane containing the first and second directions, its blind end being turned upwards, on the side towards which the lifting force will be exerted.
  • the nut 71 is then rotated to bring the head 30 into abutment with the blind end of the groove 71.
  • the shackle 72 then extends in the first direction X-X ', or is slightly inclined with respect to the first direction . We are in the situation of the Figure 1A .
  • the force exerted by the means on the lifting anchor is oriented substantially along the first direction X-X ', and is indicated by the arrow F of the Figure 1A .
  • the force exerted by the lifting means is oriented in the second direction Y-Y ', as shown in FIG. figure 1C , the shackle 72 also extending in this direction.
  • the head 30 is always at the blind end of the groove 71.
  • the lifting means exert a force along the second direction Y-Y 'on the anchor 2.
  • the boss 40 projects in the first direction XX 'with respect to the rod 20, on an upper side thereof, and has substantially the same width as the rod in the third direction Z-Z'. It extends in the second direction YY 'along the head 30 and along the outer portion 21 of the rod, and forms a shoulder 25 on a side opposite to the head 30.
  • the boss 40 increases the rigidity of the rod 20 in the first direction X-X ', and prevents the rod from deforming during the lifting operation. Such deformation would cause the nut 71 to come against the surface of the reservation 13, damaging the concrete at the point of contact.
  • the boss 40 extends substantially along the entire head 30 of the anchor, and projects in the first direction XX 'relative to the periphery of the head 30. It follows that when the head 30 is in abutment with the blind end of the groove 71, the boss 40 is interposed between this end and the head 30.
  • the presence of the boss 40 is particularly advantageous when the anchor 2 cooperates with a nut 71 carrying a substantially radial actuating lug 712.
  • the tab 712 extends upwardly in the first direction X-X ', in the immediate vicinity of the small face 12 of the panel 10.
  • the presence of the boss 40 along the head 30 causes the pivoting stroke of the nut 71 to pass the head of the orifice to the blind end of the groove is shorter, so that the leg 712 is further away from the small face 12 of the panel 10. The risk that the leg comes to rub against the small face 12 and damage the concrete is removed.
  • the anchor 2 comprises at least two oblique anchoring wings 50 extending along the rod 20 from the boss 40, on two opposite sides of this rod 20, in a direction oblique to the first and second directions XX 'and Y-Y', in a general direction opposite to the head 30.
  • the two oblique wings 50 are thin, and extend in the same plane substantially parallel to the third direction Z-Z '.
  • These oblique wings 50 originate immediately behind the recess of the reservation 13, at the shoulder 25 and widen regularly along the third direction ZZ 'from the boss 40.
  • Each has a relatively small width according to the third direction ZZ 'at the shoulder 25, this width increasing steadily when following the wing in the oblique direction away from the shoulder 25.
  • Each oblique wing 50 extends on a side opposite the boss 40 along the rod 20 by a second anchoring wing 60, these second wings 60 being mutually parallel and extending in a longitudinal direction from the oblique wings 50 .
  • These second wings 60 are for example constant widths along the third direction Z-Z ', but may also have a variable width.
  • each second wing 60 extends on a side opposite the oblique wings 50 along the rod 20 by a third anchoring wing 65 extending in the same longitudinal direction as the second wings 60.
  • These third wings 65 are narrowed regularly along the third direction ZZ 'from the second wings 60.
  • Each has a relatively larger width in the third direction ZZ' at its end closest to the second flange 60, this width by decreasing regularly when following the third wing in the longitudinal direction away from the second wing 60.
  • this width is zero, the third wing 65 thus forming a point on the opposite side of the head 30.
  • the second and third wings 60 and 65 extend substantially the entire length of the main portion 23 in the second direction YY ', substantially to an inner end 22 of the rod 20 opposite the outer portion 21.
  • each of the second wings 60 along the third direction ZZ ' is substantially equal to that of the main portion 23 of the rod 20.
  • the respective maximum widths of the oblique wings 50 and the third wings 65 are also substantially equal to the width of the main part 23 of the rod 20.
  • the oblique wings 50 considered in section perpendicular to the oblique direction, have trapezoidal sections, touching the rod 20 by their large bases.
  • the second wings 60 and the third wings 65 considered in section perpendicular to the longitudinal direction, have trapezoidal sections, touching the rod 20 by their large bases.
  • the oblique wings 50, the second wings 60 and the third wings 65 thus have a decreasing thickness from the rod 20 towards an outer free edge opposite the rod 20.
  • the wings may have triangular sections, of decreasing thickness from the rod 20.
  • the thickness of the second or third flange is here referred to as the dimension of the latter considered in a direction perpendicular to both the longitudinal direction and the third direction Z-Z '.
  • the thickness of the oblique wing is the dimension of the latter considered in a direction perpendicular to both the oblique direction and the third direction Z-Z '.
  • the free edge of the oblique wing 50 deviates from the rod 20 from the shoulder 25, and extends obliquely to one end of the free edge of the second flange 60. Similarly, the free edge the oblique wing 50 deviates from the rod 20, and extends obliquely to another end of the free edge of the second wing 60.
  • the figure 3 shows that the main part 23 of the rod 20, seen in section perpendicular to the second direction YY ', has a rectangular section elongated along the first direction X-X'.
  • the ratio of dimensions between the large and small sides of this rectangular section is of the order of two.
  • the main part 23 of the rod 20 is thus delimited by two long sides 24 planes, mutually parallel and opposite, perpendicular to the third direction Z-Z '.
  • the oblique wings 50, the second wings 60 and the third wings 65 extend along these long sides 24.
  • the thickness of the wings at the rod 20 is about one third of the height of the large faces 24 considered in the first direction X-X '.
  • the thickness of the wings at their respective free edges is small relative to the height of the large faces 24.
  • the oblique wings 50, the second wings 60 and the third wings 65 are each delimited by convergent upper and lower faces 80 and 81 constituting the two opposite non-parallel sides of the trapezoidal section. .

  • the base of the eye 90 that is to say the part of the eye 90 farthest from the end portion 21 following the second direction Y-Y ', preferably has two opposite ends flared, so that the hairpin line is, as soon as it is placed in the eye, in contact with the inner surface of this eye.
  • the inner end 22 provided with an eye 90 can be replaced by a conical foot with an axis parallel to the second direction YY ', converging towards the head 30, so as to create an compression zone towards this head.
  • the anchor comprises a cylindrical hole 91 of axis parallel to the third direction Z-2 ', intended to receive a straight cylindrical bar of short length.
  • the diameter and the length of the bar and the hanger are determined by calculation, according to the dimensions of the panel and its mass.
  • the anchor is self-sufficient in a controlled use, that is to say for the handling of panels of masses and dimensions in accordance with the requirements of use associated with each anchor model.
  • the use of the hanger and / or the bar makes it possible to increase the safety factor of the anchor.
  • the second wings 60 and the third wings 65 all extend in the same plane substantially parallel to the second direction YY '. This plane is located substantially halfway up the main part 23 of the rod 20, the height being considered along the first direction X-X '.
  • the second wings 60 are thus arranged in a plane passing through the axis of the rod 20.

  • the third wing 65 has in its longitudinal direction a length less than the length of the oblique wing 50 in the oblique direction.
  • This oblique direction forms an angle of about 30 ° with the first direction X-X 'and about 60 ° with the second direction Y-Y'.

  • the upper faces 80 of the three wings 50/60/65 contribute to generate by reaction in the concrete, during the application of the lifting force, a compression zone eliminating the risk of punching. This zone develops in a flared shape from the wings to the surface of the panel, and gives the anchor its ability to resist tearing. This resistance is proportional to the volume of concrete included in the area.
  • This zone is here particularly wide, first of all because of the orientation of the upper faces 80, which form an angle of more than 90 ° with respect to the long sides 24, and then because of the cumulative length of the three wings, which extend substantially along the entire main portion 23 of the rod 20.
  • the lower face 81 of the oblique wing 50 contributes to creating a compression zone.

  • This oblique direction forms an angle of about 30 ° with the first direction X-X 'and about 60 ° with the second direction Y-Y'.
  • the compression zone formed during the lifting is larger than in the first embodiment, because the second wing is offset downward.
  • the downward shift is not limited to the position of the underside of the main portion 23 of the rod 20. In extreme situation, it is possible to extend the portion 23 locally to allow the wings 60 and 65 to be positioned very far below. of the longitudinal axis of the anchor 20 in the second direction YY '. This could be justified for lifting operations excluding rollover.
  • the hole 91 is disposed at mid-height of the main part 23, above the second wing 60, at the end of this wing integral with the oblique wing 50.
  • the second and third wings can also be arranged on the large faces 24 at an intermediate height between the positions of the first and second embodiments. The exact position is determined by calculation, as a function of the geometry of the panel 10. Generally, the more the panel 10 is thin in the first direction X-X ', the more the wings are shifted down the large face 24 according to the first direction X-X ', to create a larger compression zone in lifting.
  • the second wings 60 and the third wings 65 all extend in the same plane as the oblique wings 50.

  • the lower faces 81 of the three wings contribute to create the compression zone, this zone being therefore more extensive than in the first two embodiments.
  • the compression zone is substantially the same as in lifting, because the wings form medial diagonals of the long sides 24.
  • the hole 91 is disposed at the bottom of the main part 23, under the oblique wing 50.
  • anchor 2 is symmetrical with respect to a median plane containing the first and second directions X-X 'and Y-Y'.
