Definitions

  • the present invention relates to a formwork intended to reinforce a concrete wall or similar material.
  • This formwork consists of two formwork walls placed one opposite the other and connected by connecting elements hinged to the walls shuttering by means of stiffeners integral with the shuttering walls. Space separating the formwork walls, after unfolding, is filled with a material such as concrete.
  • Document PCT / IB02 / 02895 describes a formwork comprising an outer wall and an inner wall, these walls, called formwork walls, comprising generally circular connecting elements articulated on the walls and vertical stiffeners formed by profiled bars generally in the shape of a U. Reinforcement elements are introduced between the lateral sides of the profiles of two stiffeners placed opposite each other.
  • Each frame member includes at least one vertical bar and at least two horizontal crosspieces adjusted to slide inside the stiffener profile.
  • This reinforcing element is added after the deployment of the formwork walls by sliding in the stiffeners which act as guide rails.
  • the U shape of these stiffeners ensure the maintenance and stability of this reinforcing element while facilitating its insertion.
  • a folded formwork will have a thickness corresponding to the sum of thicknesses of the formwork walls plus twice the height of the U-profiles of stiffeners.
  • height of the stiffener is meant the height measured on the face outside of the lateral sides (branches of the U) of the profile.
  • a large site requires a large number of forms of various dimensions that you have to move from one place to another with a minimum of trips.
  • the purpose of the present invention is to minimize the size of the formwork prefabricated both in terms of storage after assembly and in terms of transport to and during the construction site.
  • a foldable formwork for concrete wall with two walls parallel formwork placed one opposite the other and connected by elements of connection articulated to the shuttering walls by profiled bars in general shape of U secured to the formwork walls by means of vertical stiffeners formed, the opening of the U being directed towards the shuttering wall located opposite, characterized in that a stiffener of a shuttering wall is offset from the corresponding stiffener located opposite on the opposite formwork wall, the offset allowing a lateral side of a stiffener to penetrate between the sides sides of the stiffener located opposite when the formwork is folded.
  • the formwork provided with offset stiffeners according to the invention reaches a thickness minimal, when folded.
  • the thickness is reduced by the interpenetration of stiffeners in each other to correspond only to the sum of the thicknesses of the formwork walls, plus about once the height of a stiffener. This gain in thickness makes it possible to stack a greater quantity of forms and, by Consequently, space and transport costs can be saved.
  • the offset of the stiffeners is adapted so as to allow the places reinforcing elements by guide between the lateral sides of the stiffeners as described above.
  • Figure 1 illustrates the unfolded formwork with an external formwork wall (1) and a interior shuttering wall (2). These walls are made up of screens allowing passage water and retaining the concrete when it is poured into the space separating the shuttering walls (1, 2).
  • the shuttering walls (1, 2) are connected by connecting elements or stirrups (3, 3 ') generally in the form of a zigzag making it possible to maintain a fixed spacing between the walls.
  • Stiffeners 4 are placed vertically along the shuttering walls (1, 2) to ensure the rigidity of the formwork. It should be noted that the first and last stiffeners must be placed near the ends of the walls (1, 2) in order to preserve the parallelism of said walls over their entire length after pouring the concrete. In effect, the absence of a stiffener in these places can cause the spacing of the walls to their end under the pressure of concrete.
  • the connecting elements (3, 3 ') separating the formwork walls are articulated to walls (1, 2) and fixed to them by means of suitable fasteners and spacers.
  • the stiffeners (4) are in the form of U-shaped profiles, the opening of which is directed towards the space separating the formwork walls.
  • a wall stiffener is offset from the one opposite so that the axes of symmetry (a, a ') of the section of the U-profile of each stiffener passes between the two lateral sides of the stiffener opposite.
  • Figure 2 shows the folded formwork. grace at the joints of the connecting elements (3, 3 '), the formwork folds by folding connecting elements (3, 3 ') against the inner faces of the walls (1, 2).
  • the joints of the connecting elements are located between the stiffeners (4) and the shuttering wall (1, 2) on a horizontal segment (5) of said elements and parallel to said wall.
  • the segment (5) rotates around its axis longitudinal.
  • the horizontal articulated segment (5) has a longer length to the width of the stiffener (4).
  • this segment (5) is offset by a distance (d ') relative to the stiffener (4).
  • This distance (d ') corresponds at least to the offset (d) of the axis (a) of a stiffener (4) with the axis (a ') of its opposite.
  • the stiffener (4) is off-center on the horizontal segment (5) of the connecting element (3, 3 ').
  • FIG. 3 illustrates a formwork reinforced by reinforcing elements (6) introduced in the space separating the formwork walls (1, 2) and between the lateral sides of two facing stiffeners.
  • Each reinforcing element comprises at least one vertical bar and at least two horizontal cross members adjusted to slide at inside the U-profile of the stiffeners.
  • the present invention also relates to a wall in which a formwork with staggered or staggered stiffeners are used. Concrete is poured between the walls formwork, the mesh structure of which acts as a water-draining filter. The formwork thus embedded and embedded in concrete constitutes a reinforcement guaranteeing a large robustness to the wall.
