Definitions

  • the invention relates to a formwork comprising two shuttering walls placed opposite and connected by articulated connecting elements to maintain the walls, either at a spacing defining an interval intended to receive a filling material such as concrete, either folded for storage and transport.
  • a formwork of the aforementioned type is known from patent FR-A-2 675 181.
  • the articulated connecting elements allow reduce the number of assembly operations, and facilitate the installation of the formwork while in it retaining its strength and compliance with standards safety and manufacturing, this with a structure slight.
  • One of the results that the invention aims to obtain is a formwork of the aforementioned type which allows to further increase the strength of the concrete walls obtained.
  • the invention relates to a formwork comprising two shuttering walls placed opposite and connected by articulated connecting elements to maintain the walls, either at a spacing defining an interval intended to receive a material filling such as concrete, be folded for the storage and transportation.
  • the articulated connecting elements consist of elongated folded elements noticeably zigzag.
  • Each elongated element folded has staggered opposite parts connected by tie rods inclined in opposite directions on either side of each of the opposing parties.
  • Opposing parties alternating of all elongate connecting elements are aligned parallel to each other and are hinged to the walls, preferably by means of fixing allowing only one degree of freedom in rotation around articulation axes formed by said parts opposite.
  • the invention also relates to a wall, in particular in concrete incorporating this lost formwork, the elements of articulated link, which after having served in a first time to facilitate transport and installation of the formwork, constitute, once the formwork is installed, a hooping substantially increasing the resistance wall, thanks to their shape and layout particular ensuring the distribution of forces within the wall described above.
  • this formwork 2 includes two shuttering walls 3 kept at the spacing required by at least one device 4 of articulated link.
  • This connecting device 4 is articulated with each shuttering walls 3 by means of vertical stiffeners 5. This joint keeps the walls 3 either at the required spacing (as illustrated in the Figures), either folded for storage and transport, thus facilitating the installation of the formwork.
  • These formwork walls 3 will advantageously consist of a trellis whose meshes are determined to drain excess water from the concrete. he may be expanded metal panels provided with vertical stiffeners. The stiffeners 5 are for example fixed on the walls 3 using lugs forming hooks.
  • the connecting device allows to overcome this difficulty.
  • the device 4 makes it possible to modify considerably the distribution of stresses to inside the walls, when charging them. Indeed, the higher the pressure that results from the charge exercised along a longitudinal axis is higher and the higher the compression stress on the skin 3, so the effect of hooping, increases.
  • the device 4 of connection includes at least two tie rods 4A inclined in direction opposite on either side of a median plane M orthogonal to the shuttering faces, and the ends of these tie rods 4A present a fraction of the tie rod connection means 4A with the corresponding shuttering wall 3, preferably surrounding the stiffener 5 and articulated on it at the exclusion of any other degree of freedom, particularly in translation.
  • the connecting devices 4 are combined between them by opposite straight parts 6 to form at least one group 7 of tie rods.
  • This part 6 extends substantially in a plane parallel to the shuttering faces over a predetermined length and preferably equal to the width of the stiffener 5 in order to link in translation the device 4 for connection with the stiffener 5.
  • This group 7 of tie rods is formed from a elongated element 7A folded substantially in a zigzag for form a series of waves substantially sawtooth.
  • the section of this elongated element 7A is circular or polygonal.
  • the wall is obtained using several forms elementaries 10 of the aforementioned type arranged side by side.
  • the length of the elongated element 7A folded in a zigzag is greater than the length of the formwork panel 10 to through which it extends so that the end 7B of an overhanging panel can hang on the adjoining panel (see Figure 3).
  • This 7B end will be shaped for example like a hook support on a stiffener 5.
  • At least some 4A tie rods will eventually be provided with heating elements (not shown), such thermistors to form a radiant wall.
  • heating elements not shown
  • the use of thermistors generates heat by creating a potential difference between the walls shuttering.
  • the part 6 of element 7A is fixed to the shuttering wall 3 by fixing means with a single degree of freedom in rotation around an axis parallel to the plane of the shuttering faces, perpendicular to the vertical axis of the stiffeners 5 and to the exclusion of any other degree of freedom.
  • the articulated parts of the connecting elements could be angled, as shown in dotted lines in Figure 3, and articulated in the middle of a vertical stiffener of the type illustrated 5 or of reduced dimensions 5 ', or articulated behind 5 "wedge-shaped vertical stiffeners.
  • the connecting elements 4 of a formwork panel are for example arranged in column with the top of their aligned waves ( Figure 2), or two elements of link 4 are staggered ( Figure 1) so that the vertices of the waves are offset. We constitute thus a three-dimensional connection.
