Definitions

  • the invention relates to an improved adhesion reinforcing bar for a reinforced concrete part, in particular a beam, a slab or a column and also covers the reinforcement cages using such bars and their methods of production.
  • reinforced concrete consists in combining the qualities of compressive strength of concrete and tensile strength of metal reinforcements.
  • a reinforced concrete construction element behaves in fact like a composite part in which the reinforcing bars and the concrete, which have neighboring expansion coefficients, deform in the same way under the effect of the applied stresses, at least up to a limit effort.
  • this part comprises, on either side of a neutral axis, two parts subjected, respectively, to compressive forces received by the concrete and to tensile stresses concealed mainly by the longitudinal reinforcing bars. It is therefore determined by calculation the cross section that should be given to each bar tense to withstand the forces applied, given the distance between the facing face of the compressed part and the center of gravity of the bar.
  • the entire reinforcement of a reinforced concrete element has the shape of a cage consisting of two layers of longitudinal bars, respectively active and passive, interconnected by transverse stirrups that allow the manipulation and implementation of the entire cage and resist, on the other hand, sharp forces.
  • These macrocracks allow the penetration of moisture and aggressive agents in contact with the frame. As they appear, in the first place, on the side where the coating is less important, it is necessary to leave a minimum coating distance between a reinforcing bar and the corresponding facing face of the part to prevent corrosion of the coating. bar and bursting of the concrete.
  • This coating distance imposed by the regulations may be, for example, 30 mm.
  • each flat bar can be chosen so as to present the cross section determined by the calculation in the usual way in order to withstand the forces applied.
  • Such flat reinforcing bars are, therefore, of equal section, equivalent to the round bars usually used but, for the same coating distance, the axis of the flat bar is farther from the center of gravity of the beam than that a round bar of the same section and the resistance of the beam can, thus, be improved.
  • the object of the invention is to solve such problems and thus avoid the disadvantages of this ancient technique while benefiting, however, from all the advantages brought by the use of flat bars with improved adhesion as reinforcements of reinforced concrete.
  • the present invention thus relates, in a general manner, to the realization of an improved adhesion reinforcement bar for a piece of reinforced concrete, consisting of a metal profile extending in a longitudinal direction, having the form of a flattened strip of substantially rectangular cross-section, with two opposite broad faces extending between two lateral sides and having a plurality of parts protruding anchoring spaced longitudinally from each other and resting on the concrete in a direction opposite to a tensile force applied to the bar.
  • each of the two broad faces of the strip is provided with a series of elongated lock-shaped anchoring portions separated from one another by groove-shaped hollow portions and extending transversely over any the width of the strip, substantially to the lateral sides thereof, and each of said elongated locks protrudes over a small height, not exceeding one quarter of the thickness of the strip and has, in cross section , a substantially trapezoidal profile, with a relief face of small width relative to its length and two inclined connecting flanks with the elongate bottom of the adjacent grooves which constitute, for each latch, two inclined bearing faces, each in one direction , on the encasement concrete, said inclined faces each having an elongated shape extending between the two sides of the strip, so as to distribute the support forces over the entire width of the strip. the latter.
  • the elongate locks on each side of the strip are spaced from each other by a constant pitch not exceeding half the width of the strip and preferably between one and three times the thickness of the strip.
  • the locks formed respectively on the two broad faces of the strip are parallel and the locks on one side are offset longitudinally by half a step with respect to the locks on the opposite face, so that the bottom of each groove of a first face is substantially in line with a lock of the second face.
  • the elongated locks formed respectively on the two faces of the strip extend transversely in directions inclined at a non-zero angle with respect to the longitudinal axis of the strip.
  • the elongate locks formed respectively on the two faces of the strip are inclined symmetrically, in opposite directions, with respect to the longitudinal axis.
  • the angle ⁇ of inclination of the locks relative to the axis is between 35 ° and 75 °.
  • the anchor locks provided on each broad face of the strip are in the form of interlocking V-shaped chevrons, with two straight portions inclined symmetrically on either side of the longitudinal axis of the strip.
  • the anchor locks have an undulating shape, symmetrical with respect to the longitudinal axis of the band.
  • the locks provided on each broad face of the strip extend up to a short distance from each of the lateral edges thereof, so as to leave, along each of said edges, a flat surface having a small width, of the order of 0.2 e, e being the average thickness of the strip.
  • the raised faces of the elongated locks and the bottoms of the grooves are situated, respectively, in two parallel planes extending on either side of an average plane in which are placed the two flats extending respectively along the two side edges of the strip.
  • the two planes in which the raised faces of the bolts and the bottoms of the grooves are situated, respectively, are spaced apart by a height h which can range from 0.08 e to 0.24 e, e being the thickness average of the band.
  • the connecting flanks between the raised faces of the bolts and the bottom of the corresponding grooves, which constitute, for each latch, two elongated bearing faces, each in one direction, on the concrete, are inclined at an angle at least 45 °, with respect to the raised face of said lock.
  • the invention also covers a reinforcement cage for a reinforced concrete part, comprising two layers of reinforcing bars connected by stirrups and extending at a short coating distance, respectively, from two facing faces spaced apart from the room.
  • At least one of the two plies of the cage consists of such flat bars with improved adhesion and the stirrups are also formed of flat metal strips, alternately welded on the raised faces of the elongated anchoring locks formed on each of the broad faces of said flat bars.
  • the invention also covers a method of making such reinforcing bars with improved adhesion.
  • a metal strip in the form of a flattened strip having two opposite large faces and centered on a longitudinal axis is produced first, then this flattened strip is subjected to a rolling pass between two rollers rotating around axes. parallel and orthogonal to the longitudinal axis of the strip, said rollers being provided on their periphery with spaced-apart impressions, for the formation, by rolling, of elongate locks separated by parallel grooves, on each of the two broad faces of the strip. bandaged.
  • These two rolling rolls are each provided, on their periphery, with an alternation of cavities and teeth intended to form, respectively, the locks and the grooves on each of the broad faces of the band and extending between two smooth portions. of small width, for the formation of two flats along the two lateral sides of the strip.
  • these lock formation impressions are regularly spaced along the periphery of each of the rolling rolls, so as to form locks. away from a constant step. But in some cases, the impressions may be distributed along the periphery of each of the rolling rolls, so as to periodically vary the spacings of the locks made on each broad side of the strip.
  • FIG. 1 which is a half-view of detail in longitudinal section, there is shown, in perspective, a first embodiment of a reinforcing bar according to the invention consisting of a flat metal strip 1 centered on a longitudinal axis x ' x and having a rectangular cross-section with two opposite large faces, respectively upper and lower 10 ', extending between two lateral sides 11.
  • Each of the two wide faces 10, 10 'of the strip 1 is provided with a series of regularly spaced elongated protruding portions 2.2', separated from each other by groove shaped portions 3, 3 '.

  • the ratio of the nominal width to the nominal thickness is normally between 4.5 and 6.
  • the spacing pitch of the locks will therefore be between one and three times the thickness of the band.
  • the bolts 2 thus brought together, as well as the grooves 3 which surround them, therefore have an elongated rectangle shape, with a raised face 21 of very small width relative to its length.
  • Such a reduced spacing of the locks makes it possible to arrange three or four parallel locks over a strip length corresponding to its width whereas, in the old arrangement of the document FR-A-765.943 the locks were spaced a distance of the order of the width of the band.
  • the height of the locks should not exceed one quarter of the thickness e of the strip and will preferably be between 0.08 e and 0.25 e.
  • the connecting flanks 22, 23 also have the shape of elongated rectangles, of very small width relative to their length.
  • the bearing faces thus formed thus make it possible, on the one hand, to reduce the individual abutment forces applied by each latch on the coating concrete and, on the other hand, to distribute these forces over the entire width of the strip. .
  • the elongated latches 2 are directed perpendicularly to the longitudinal axis x 'x of the band 1 and are regularly spaced from the pitch c, while the latches 2' of the opposite face 10 'are offset longitudinally by a half-step.
  • the bottom 31 'of each groove 3' of the lower face 10 ' is thus substantially in register with the raised face 21 of a latch 2 of the upper face 10.
  • the latches 2 '2' are formed on the two faces 10, 10 'of the strip and they have a very small height, the thickness of the active part resistant to the forces traction remains of the same order as the nominal thickness of the bar reinforcement and is practically preserved throughout its length, in the direction of application of the tensile force.

  • the inclined flanks 22, 22 'of the grooves 2, 2' which extend substantially over the entire width of the strip, have a substantially constant height, such as so that the forces applied by each lock on the concrete, when the bar is subjected to traction, are evenly distributed over the entire length of the lock, that is to say over the entire width of the bar 1.
  • each bar has, in cross section on its axis, a rectangular profile of small thickness relative to its width
  • the projection of the locks in the longitudinal direction of the tensile force, which corresponds to the stress transmitted by the concrete bar may extend over at least 75% of the perimeter of the bar, calculated from the nominal section of the bar. This results in a lower risk of shearing the joint.
  • the longitudinal spacing of the average planes P, P 'of the support forces on the concrete corresponds, on each face 10, 10' of the strip, to the reduced pitch c of spacing of the elongate locks 2,2 'which , as indicated above, is less than half the width of the
  • the abutment stresses, which are exerted along two directions inclined symmetrically on either side of the mean plane of the strip, along the two series of parallel planes P, P ' are slightly spaced apart. others, are therefore distributed substantially uniformly over the entire width and the entire length of the bar 1.

  • the metal cross-section on which the tensile force T is applied remains substantially constant over the entire length of the strip, which therefore fully participates in the resistance, while the resistance of a conventional reinforcing bar Circular section should be calculated only according to its nominal diameter, without taking into account the volume of metal corresponding to the anchoring parts.
  • reinforcing bars according to the invention comprising a large number of loosely spaced and low height locks, makes it possible to reduce this risk of embrittlement when the bar is bent, for example to form sticks. anchoring at the ends or to adapt the profile of the bar to the shape of the part or the distribution of the stresses in the concrete part.
  • latches 2 and the grooves 3 extend substantially over the entire width 1 of the strip, their ends may form dangerous sharp angles for the handling of the bar and may facilitate cracking of the concrete during the tensioning of the bar.
  • the latches 2 and the grooves 3 extend transversely only over a width a little smaller than that of the flat strip 1, so as to leave along each of the two edges side of the latter, a flat surface 12 having a small width, for example of the order of 0.2 e, e being the thickness of the strip at each of its sides 11.
  • each of the two faces 10, 10 'of the bar 1 has, in a direction perpendicular to the longitudinal tensile force T, an alternation of protruding portions and recessed portions corresponding to a plurality of inclined locks 2a, 2b, 2c of which the bearing faces 22 intersect the cross-sectional plane.
