Definitions

  • the present invention relates to a prefabricated formwork element arranged to produce a formwork intended to provide, in a slab of a construction, a through reservation for the passage of a staircase, an elevator or the like, said formwork element comprising a profile provided with at least one vertical panel arranged to delimit at least a rectilinear part of the edge of said through reservation.
  • the invention also relates to a formwork obtained from at least one formwork element, as well as a method for manufacturing a slab of a construction comprising a through reservation for the passage of a staircase, an elevator or similar.
  • a through reservation made in a slab of a construction allowing the passage of a staircase, an elevator, a chimney flue, etc. is commonly called a hopper.
  • the realization of this through reservation requires the installation of a formwork usually made from a wooden frame or the like delimiting an open space in the slab.
  • the publication EP 0 927 796 A1 describes a formwork panel intended to form the edge of a slab. It is in the form of an L-shaped panel at a right angle which rests by its horizontal wing on a lower wall and on a bottom of formwork.
  • the vertical wing for its part, comprises a plurality of vertical channels for receiving fixing means allowing the fixing of the formwork panel to the formwork bottom.
  • These fastening means are distinct and separate elements of the formwork panel and are fixed to the bottom of the formwork by nailing.
  • a guardrail can also be attached to the formwork panel by means of attachment means attached to the formwork element.
  • This formwork panel does not make it possible to protect an opening made in a slab using a protective net. It is intended to form the edges of a slab and not an opening delimited by a closed perimeter.
  • the publication EP 2 415 950 A2 relates to fall protection for an opening, this protection comprising a net and a frame formed of several tubes inserted by their ends into corner elements, which comprise means for fixing the protective net.
  • This document does not describe formwork elements, since the frame is formed by tubes and not by vertical formwork panels, and a tube is not suitable for allowing the formwork of a opening. Finally, this document does not teach fixing means for guardrails.
  • the present invention aims to overcome these drawbacks by proposing a formwork solution making it possible to secure a through opening in a slab of a construction in a simple, rapid and reliable manner during all the phases of the construction site, in complete safety from the lower floor, and this from the installation of the formwork, this formwork solution being versatile to be able to adapt to any form of through reservation and floor.

  • the means for fixing said fall arrest net comprise at least one vertical attachment rod, and forming with said vertical panel a space to receive a part of the perimeter of said fall arrest net around said attachment rod. Said at least one hooking rod of said fixing means of said fall arrest net can be accessible from the side opposite said horizontal panel.
  • the receiving means may comprise at least two flat-bottomed reservations distributed on the underside of said horizontal panel and arranged to receive the flat ends of said supporting members.

  • assembly means arranged at the opposite ends of the vertical panel and arranged to allow the assembly of adjacent formwork elements aligned or at right angles to form a formwork.
  • These assembly means may comprise at one end a male end piece and at the other end a female end piece of a shape complementary to said male end piece, said end pieces extending vertically and delimiting an interlocking abutment such that the formwork elements adjacent panels are assembled by a vertical interlocking and that their horizontal panels are at the same level.
  • the formwork element is preferably a one-piece piece.
  • the invention relates to a formwork of the type indicated in the preamble, characterized in that it comprises at least one formwork element, as defined above, forming a polygonal closed frame.
  • the formwork may also comprise a plurality of formwork elements assembled together by said assembly means provided at the opposite ends of each formwork element to form a polygonal closed frame.
  • the formwork can also consist of a single piece.
  • the horizontal panels of said assembled formwork elements are preferably oriented outside of said closed polygonal frame delimited by said formwork.
  • It may also comprise at least two straight covering elements each arranged between two aligned and spaced formwork elements to form a polygonal closed frame of which at least two opposite sides are not multiples of a formwork element.

  • the formwork element 1 is preferably made in one piece, obtained by molding, injection or the like. Of course, the formwork element 1 can be manufactured in two separate parts then assembled, without this variant modifying the extent of the protection. For the manufacture of the formwork element 1, preference is given to a synthetic material, such as plastic, for example polypropylene, or the like, or a composite material. Of course, these examples are not limiting.
  • stiffening means are incorporated into this formwork element 1, allowing it to be given the desired mechanical strength for that it can fulfill its various functions, namely formwork functions for a slab cast in a hydraulic material, but also holding and support functions for existing collective protective equipment protecting workers against falls of people and 'object.

They also have a section complementary to that of the uprights M of a guardrail G to receive them by simple male/female mechanical interlocking requiring no additional fastening means, as shown in figure 4 .
  • the height of the tubular housings 141 is sufficient to ensure effective retention of the guardrail G without the uprights M being able to come out of said housings accidentally.
  • the height of the tubular housings corresponds to the standards in force. In the example shown, this section is circular. But this example is not limiting and extends to any other section known for vertical uprights of a guardrail or any other equivalent collective protective equipment. Similarly, the design of these fastening means 14 may differ from the example shown, the main thing being that the uprights M of a guardrail G can be nested vertically from above the formwork C simply and quickly, without tools to prevent access to the interior of the formwork C. On the other hand, the present invention is not limited to two tubular housings 141 per formwork element 1.
