Definitions

  • the subject of the present invention is a reinforcing link panel intended in particular, but not exclusively, to allow the connection between the reinforcements of a first part of the structure obtained by a first concrete pour and the reinforcements of a second part of the work which can be obtained by a second pouring of concrete, or by assembling various materials, such as bricks for example, said second part having to be made integral with the first.
  • connecting means which must be an integral part of the two constituents of the 'work.
  • These means may for example consist either of a set of connecting reinforcements taking up the forces of the reinforcements included in the two parts of the structure, or of crimped and / or tapped connection sleeves, or any other suitable means.
  • connection must be effective, that is to say capable of ensuring a good transmission of forces between the two parts of the structure.
  • the means used must be able to ensure correct positioning of the connecting elements during the construction of the structure, the casting of the first phase concrete is usually carried out in a formwork which recesses the outline external of the first part of the book.
  • a first end is connected, for example by covering the reinforcements of the concrete of the first phase.
  • the second end of the connecting reinforcements can then either pass through holes drilled in the formwork and thus be in the waiting position for pouring the second phase, or be folded back inside the formwork, this second solution being most commonly used.
  • said second ends After removing the formwork, usually made of wood, said second ends are unfolded so that they are in an adequate position to fulfill their role of transmitting forces to second phase reinforcements, by covering or by any other means.
  • connection reinforcements are used, the folded ends are coated with concrete and it is necessary to locate them, which is not always obvious, then to remove them with a jackhammer with all the risks of injury of the steel that that implies.
  • This difficulty is increased when the surface of the wall is not planar and has protuberances, in particular in the case of walls poured into the ground.
  • the connecting reinforcements have been properly positioned before pouring, there is always a risk of displacement during the various treatments that the concrete is made to undergo, such as vibration for example.
  • the protruding loops pose problems of transport to the site of the panels and access to the free ends is problematic and requires the disintegration of the panel.
  • the panel of connecting reinforcements for reinforced concrete produced by molding synthetic foam and which can be fixed by one of its faces against the interior face of a formwork is characterized in that it has a set of regularly distributed transverse orifices opening onto the face intended to be applied against the formwork in grooves whose depth is at least equal to the diameter of a connecting reinforcement, which makes it possible to insert the latter, after folding , inside the panel immediately before fixing the panel to the formwork.
  • the folded reinforcement appears on the surface of the concrete and it is easy to unfold it to connect it to the reinforcement of the second phase concrete.
  • connection reinforcements are used, the orifices are approximately the same size as the section of the connection reinforcements, their spacing being that which is defined by the calculations.
  • the panel present on its face intended to be applied against the formwork of the cells or of the grooves.
  • these preferably have a depth equal to one or more reinforcement sections, each groove corresponding with one or more orifices and extending in a substantially longitudinal direction.
  • the panel to have a bearing face of shape corresponding to that of the formwork (and for example, flat) against which it is applied.
  • the purpose of the cells or grooves is to allow the insertion of the folded ends of the connecting reinforcements into the panel.
  • the folded ends of the connecting reinforcements are inserted in the grooves before fixing the panel to the formwork, their opposite ends projecting from the other side of the panel.
  • the grooves can be inclined relative to the longitudinal direction of the panel so as to avoid their superposition.
  • connection reinforcements form loops, on the second phase concrete side, it is known to bend the connection reinforcements in "U".
  • the base of the »U « can then be folded a second time, perpendicular to the branches of the »U «. It is the open loop thus formed which is introduced into a groove or a cell.
  • the loop or the "U” is thus wrapped over most of its periphery by the plastic foam which tends to close on the steel. This coating is improved by the pressure exerted on the face of the panel, when the latter is fixed to the formwork.
  • the »U « is unfolded and forms a loop, protruding from the first phase concrete, inside and around which the second phase concrete sets.
  • the panels are used for positioning and maintaining connecting reinforcements.
  • the orifices 2 are small and grooves or cells 16 must be provided on the face of the panel applied against the formwork.
  • one of the faces of the latter have a shape corresponding to that of the wall of the formwork against which it is applied. , at least the edges of the panel to ensure good contact with this wall of the formwork.
  • the shape of the internal wall of the formwork is not always planar and the invention can be applied with advantage in cases where said wall has a non-planar shape and, for example, where it affects the shape of a cylindrical sector.
  • the grooves on the rear face of the panel may consist of simple substantially longitudinal grooves into which the abovementioned orifices open, said grooves being designed and made inclined relative to each other so as to avoid an anarchic superposition of steels, each of the bars having to be inserted conveniently.
  • the orifices 2 and the grooves 16 can be obtained directly by overmolding the frames. These are then placed in the mold, the parts intended to be incorporated in the second phase concrete being placed against the bottom of the mold so as to be easily identifiable and unfoldable after formwork removal.
  • Figs. 2 and 3 show an example of the use of connecting reinforcements, introduced into it after molding or machining.
  • the process for implementing such a panel is identical to the previous one.
  • the connecting frames 12, folded twice so as to form a loop 15, perpendicular to the strands 13 and 14, are slid into the panel 1.
  • the panel 1 is then fixed, in an appropriate position, on the formwork 3 so that the strands 13 and 14 overlap with the reinforcements of the first phase concrete (not shown in FIGS. 2 and 3), the face 18 being applied against the formwork while the face 19 may have surface reliefs to improve the attachment of the second phase concrete 11 to the concrete 9 in the cavity left free after disappearance of the panel.
  • Fig. 2 shows in section the arrangement of the connection reinforcements after pouring the concrete 9.
  • the loops 15 are unfolded, the panel 1 then being destroyed, which poses no problem given its friability.
  • the loops occupy the position shown in FIG. 3 which is a section through a plane along the line VI-VI of FIG. 2.
  • the loops 15, anchored in the concrete 9 by the strands 13 and 1-4 may constitute the reinforcements of the second part of the structure, if the latter is of relatively small dimensions, or be connected by any suitable means , such as covering, for example, to a second system of reinforcements integrated into the second part of the structure produced by pouring concrete 11 from the second phase.
