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 integral with the first.
  • connection must be effective, that is to say ensure a good transmission of the forces between the two parts of the structure; the positioning of the connecting elements and their maintenance in good position, in particular during the pouring of the first phase concrete, must be ensured.
  • pouring of the first phase concrete is usually carried out in a formwork which reproduces in hollow the external contour of the first part of the structure.
  • connection reinforcements are used, a first end of these is connected, for example by overlapping with the reinforcements of the first phase concrete.
  • the second end of said connecting frames can then either pass through holes drilled in the formwork and thus be in the standby position for pouring the second phase, or be folded back inside the formwork, this second solution, more economical being the most commonly used.
  • the second ends After removal of the formwork, usually made of wood, the 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.
  • the first phase of reinforcing bars are provided, for example by crimping, end cap engaging the cof- f rabies concrete first phase; these end caps or sleeves are protected during casting by sealing plugs, for example made of plastic, and appear, after formwork removal, in the wall of the poured concrete, provided that they have remained well positioned during casting and hardening of the first phase concrete.
  • sealing plugs for example made of plastic
  • the present invention is based on the idea that it is possible to use such panels to simplify, improve and properly control the installation of sleeves or connecting frames.
  • the connecting panel molded from synthetic foam, which can be fixed inside. of a formwork, is characterized in that it has a set of regularly distributed orifices.
  • the diameter of the circular orifices is substantially equal to the external diameter of the sleeves whose ends can thus be trapped during casting which prevents any risk of displacement.
  • the foam panel appears distinctly and the sleeves can be easily located and rid of the plastic foam that surrounds them, for the connection of second phase reinforcements. Possibly., Said orifices can be blind so as to protect the interior of the sleeve during the pouring of the first phase concrete.
  • connection reinforcements are used, their spacings being in accordance with that which is defined by the calculations.
  • the panel has on one of its faces (that which is intended to be pressed against the formwork) substantially longitudinal grooves each of which corresponds with one or more orifices. Indeed, to obtain good adhesion of the panel to the formwork, it is desirable that the panel has a bearing face of shape corresponding to that of the formwork against which it is applied.
  • the purpose of these grooves is to allow their insertion into the panel, after they have been folded, on the formwork side.
  • the grooves have a depth of the order of diameter or several times the diameter of a connecting reinforcement.
  • the grooves can be inclined relative to the longitudinal direction of the panel.
  • the folded ends of the reinforcements are inserted into the grooves before fixing the panel to the formwork, the opposite ends projecting perpendicularly to the panel, after passing through it.
  • connection reinforcements form loops
  • the grooves take the form of an unclosed quadrilateral, two opposite sides of which open into two orifices in the panel.
  • the reinforcements are slid into said panel so that the "U" comes to fit into the corresponding groove.
  • the "U” is thus wrapped over most of its periphery by plastic foam which tends to close on the steel, therefore to coat it well, thereby protecting it from contact with concrete.
  • This coating is increased by the pressure exerted on the face of the panel; when fixing it on the formwork.
  • the "U” is unfolded and forms a loop inside which the second phase concrete sets.
  • the panel can be delivered with mounted link plates and these plates can also be molded with the panel, the loops being arranged in the vicinity of one of the walls of the mold.
  • the panel 1 intended for holding sleeves has a set of aligned holes 2, regularly spaced, the distance between the outermost holes and the side edges of the panel is preferably equal to half a step , so as to allow an assembly of panels by juxtaposition while preserving the regularity of distribution of the reinforcements.
  • the panels 1 can be assembled vertically or horizontally.
  • Fig. 2 which is a section through a vertical plane of a concrete structure after pouring of the first phase concrete 9
  • the panel 1 is fixed to the formwork 3 by means of points, for example, and the end of the sleeve 4 is inserted into one of the orifices 2 of the panel 1 which, in the example shown, is arranged horizontally.
  • the sleeve 4 has been previously crimped onto the end of a frame 5 which it is proposed to connect to the frame 6 of the second phase concrete.
  • a sleeve 7 is also crimped at the end of the frame 6, the two sleeves 4 and 6 being themselves mechanically connected by a connector 8 with double reverse thread.
  • Panels of the same structure can be used for positioning connecting reinforcements.
  • the diameter of the orifices is smaller than previously and grooves must be provided on the face applied against the formwork.
  • the shape of the internal wall of the formwork is not always flat and the invention can of course be applied to the case where this wall has the shape of a cylindrical sector.
  • the grooves may consist of simple substantially longitudinal grooves, into which the abovementioned orifices open, said grooves being inclined relative to each other to avoid overlapping.
  • the orifices 2 and the grooves 16 can be obtained directly by overmolding the frames. These are arranged in the mold, the folded loops being against the bottom of the mold so as to be easily identifiable and unfoldable after stripping.
  • Figs. 5 and 6 represent a mode of use of connection reinforcements, molded into a panel or introduced into it after molding. The process of implementing such a panel is substantially identical to the previous one.
  • the connecting reinforcements 12 folded twice so as to form a loop 15 perpendicular to the strands 13 and 14 are slid into the panel 1 if they have not been molded therewith.
  • 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. 5 and 6).
  • the face 19 of the panel 1, 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.5 shows in vertical section the arrangement of the connecting reinforcements after pouring the concrete 9.
  • the loops 15 are unfolded, the panel 1 then being destroyed which is not a problem given its friability .
  • the loops 15 occupy the position shown in Fig.6, which is a section through a horizontal plane along the line VI-VI of Fig.5.
  • the loops anchored in the concrete 9 by their strands 13 and 14 can constitute the reinforcements of the second part of the structure if the latter is of relatively small dimension or can be connected by any suitable means such as covering, for example, to a second set of reinforcements integrated into the second part of the structure produced by pouring concrete 11 from the second phase.
