Definitions

  • the present invention relates to the field of formwork for the construction of a wall or slab of concrete or similar material. More specifically, it refers to the formwork walls or shuttering panels that constitute the formwork itself.
  • a panel comprises a screen sheet extending over vertical bars called stiffeners spaced at predefined intervals attached to the screen sheet.
  • the formwork is formed by panels arranged vertically and parallel to each other opposite. They can be connected by a connecting device creating a space to be filled with a material such as concrete.
  • Such a formwork system is generally used as a formwork lost or integrated that is to say that it remains as an integral part of the wall after pouring the concrete in the space between the two panels.
  • the document WO2005042864 describes a high-strength formwork for a concrete wall comprising two parallel formwork walls placed facing each other and provided with profiled bars forming vertical stiffeners.
  • the walls are connected by an articulated connection device for maintaining the formwork walls at a spacing defining a space for receiving a filling material such as concrete.
  • the articulation of the connecting device makes it possible to fold the formwork for storage and transport.
  • the connecting device comprises a pair of horizontal straight bars parallel to the formwork walls. The bars placed one opposite the other through the stiffeners of the respective walls.
  • the connecting device also comprises a plurality of connecting bars perpendicularly connecting the two horizontal bars around which they articulate.
  • the formwork with its two formwork walls equipped with stiffeners and assembled with the connecting devices are prefabricated at the factory. It is transported to the construction site in folded form thanks to the joints of the elements of links on the stiffeners.
  • the advantage of such a formwork is its maneuverability and speed of assembly on site with a minimum of tools and manpower.
  • each step of the formwork manufacture must be optimized both in speed of execution and reliability of the components or the finished product.
  • An important component here is the formwork wall or the formwork panel designed to withstand the deformations due to the pressure and weight of concrete poured into the formwork formed by these panels.
  • the document FR2712016 discloses a method of manufacturing formwork walls comprising an expanded metal plate provided with V-shaped parallel ribs.
  • This mesh plate is attached to a plurality of stiffeners spaced at regular intervals and arranged perpendicularly to the ribs of the plate.
  • the method comprises a stapling operation of the stiffeners on the plate, a first step consists in punching off tabs on one of the faces of the stiffeners. In a second step, these tabs are folded over the ribs of the plate after passing through the mesh on each side of the ribs.
  • the document FR2497857 discloses a prefabricated panel comprising a frame formed of profiled stiffeners covered by a perforated metal sheet and at least one layer of coating material such as concrete.
  • the stiffeners comprise tabs, issuing from one of the faces of the profile, passing through the perforated sheet to be folded on the outer face thereof so as to hook said sheet to the stiffeners.
  • the document W02007 / 079989 discloses a panel for formwork of concrete walls or slabs comprising a mesh metal sheet reinforced on the one hand by a plurality of stiffeners formed of rigid profiled metal bars integral with one side of said sheet arranged parallel to each other and spaced apart at predefined intervals, and secondly by ribs integrated in the mesh of the sheet. These ribs are spaced at predefined intervals and crossing the stiffeners preferably at right angles.
  • the mesh sheet is attached to the stiffeners by crimping at at least one intersection between the ribs and the stiffeners. The crimping is performed so that at least one tongue coming from the metal of the rib maintains the stiffener through a corresponding orifice of said stiffener. The tongue is folded against the inner face of the stiffener around the edge of the orifice so as to press the mesh sheet against the stiffener.
  • the orifice is stamped in the form of a rectangle so as to create tabs both in the metal of the rib and in that of the stiffener attached to the two small opposite sides of the rectangle.
  • the tabs directed towards the inner face of the stiffener profile are then folded against this face in an area adjacent to the short sides of the rectangle.
  • the pressure of the concrete can also cause a recovery of the tongues.
  • the latter by disengaging mesh of the mesh, cause the stall of the formwork wall and deformations on the surface of the realized wall.
  • the attachment of the formwork wall to the stiffeners as presented in the document FR2497857 Moreover, there is a similar disadvantage of straightening the hook under the pressure of the concrete.
  • the object of the present invention is to significantly improve the strength of the crimping of the prior art while retaining the advantages of crimping with respect to the fixing of the mesh by welding and other fastening means.
  • crimping reduces production costs and streamlines the mass production of factory formwork panels while ensuring maximum strength for walls built with this type of formwork.

  • the formwork is placed on a substantially horizontal surface (floor or floor slab) so that the stiffeners of the panels are arranged in the vertical direction.
  • the ribs of the grid sheet perpendicularly cross the stiffeners and are therefore arranged horizontally and preferably at regular intervals over the entire height of the panel.
  • the notions of vertical and horizontal are relative because the entire formwork can be rotated at an angle of 90 °. Thus the vertical elements at the beginning become horizontal and vice versa.
  • a panel can be used as a single wall and placed either vertically against a wall to form a simple formwork, or horizontally for the realization of slabs.
  • the form is formed by two panels arranged vertically and parallel to each other. They can be connected by a connecting device creating a space to be filled with a material such as concrete.
  • a panel can be arranged vertically against a wall to form a simple formwork. It can also be used as a basis for the construction of various civil engineering works such as a slab of floor or roof, poles, beams, pillars etc.

Each abutment (7, 7 ') of width 1.2 mm in the example plays a role of locking the tongue (6) issuing from the rib (4) once bent over the edge (8) of the orifice (5).
  • the width of the orifice (5) in the vicinity of the attached end of the tongue (6) is less than the width of said orifice (5) near its center. This difference in width constituting the abutments (7) makes it possible to prevent the tabs (6) issuing from the rib (4) from leaving the orifice (5) from being pressed against the mesh sheet (2).
  • the figure 2a shows a first crimping option in which the respective tabs (6, 6 ') issuing from the stiffener (3) and the rib (4) are bent substantially at right angles to the plane of the orifice (5).
