Definitions

  • the invention is in the field of construction, and more particularly techniques for constructing concrete slabs or the like. Its purpose a modular structure supporting a formwork for the manufacture of a such a slab.
  • a method for manufacturing a slab which implements a modular structure of temporary support of formwork plates for receiving concrete, until hardened latest. More particularly, these structures are composed of elements modules assembled together in a generally planar mesh structure, which is supported by props.
  • the framework is composed of a set of primary beams supporting two by two secondary beams. The primary beams are connected to each other by abutment of a on the one hand, and transversely on the other. This connection is made, at least for some of them, through formwork heads supported by were.
  • EP 751 268 and DE 3921064 relate to a device for modular support for formwork of concrete slabs, with beams primary each comprising a base trapezoidal cell, and a middle cell with straight side walls and extending perpendicular to the partition wall. Mechanical resistance to bending of such a profile remains limited.
  • the formwork heads have a plate to support the beams primary and assemble them together. This support is done either directly, either via cooperating hooking members respectively assigned to beams and formwork heads. For example, this picking is obtained by means of notches formed in the profile, which cooperate with a protruding rim of the plate of the formwork heads.
  • the secondary beams are formed in a simple profile, such than I or square.
  • the surface of formwork rest is optimized thanks to an upper alveolus top of I, for the reception of a wooden board like beams primary.
  • the lightening of the secondary beams is obtained by openings in the walls of the profile.
  • Honeycomb tips comprising the hooking members are attached at the ends of the profiles for their connection with each other and / or with the formwork. These end pieces therefore comprise the hooking member for the support of secondary beams by primary beams.
  • the object of the invention is to increase the mechanical strength of a modular support structure for a slab formwork.
  • the primary beams each have a base cell, the side walls are curved in a convex shape, while the middle alveolus is flared towards its seat on an upper wall of the base cell, so as to give the primary beams, in their basic and middle alveolar components taken together, one conformation with double superimposed and flared cells, open in direction one over the other.
  • the basic cell 2 of the primary beams 1 has side walls 3 curved, particularly convex in shape, so that its profile is substantially shaped into at least one circular or curvilinear segment. It follows that the stiffening of the base cell 2 is directly obtained satisfactorily by this conformation, allowing in particular to avoid an inappropriate internal partitioning thereof. We will understand however, although not advantageously, that the base cell 2 perhaps incidentally compartmentalized, especially in the case where the stiffening of primary beams 1 is not supported by an arrangement particular of the medial alveolus 4 in the manner defined below.
  • the radius of curvature of the wall 3 can be variable depending on the desired inertia.
  • the middle cell 4 of the primary beams 1 has a flared conformation towards its seat on an upper wall 5 of the base cell 2, with side walls 6 which can be straight or curved.
  • These provisions are such that, in addition to the usual spacer function of the middle alveolus 4, this part of the overall stiffening of the primary beam 1, in combination in particular with the curved shape of the side walls 3 of the base socket 2.
  • the upper cell 7 of the primary beams 1 has on its faces of the interlocking members 8, such as shaped claw or bead, of the board which it is intended to receive by introduction into strength.
  • edges of the upper cell 7 of the primary beams 1 each have a return 9 to the outside.
  • this return 9 participates in the inertia of the beam.
  • these returns 9 are substantially overhanging the side troughs 10 bordering the cell median 4, so as to delimit jointly with the latter a nesting zone 11 for a wooden compensation element 12 conformed in correspondence.
  • the function of element 12 is to allow an additional support zone to the concrete reception surface, all by improving the nailing of the covering.
  • the underside of the returns 9 advantageously has a groove 13 for the reception of a cooperating socket member 14, arranged on the compensating element 12.
  • the primary beams 1 have at their base a reinforcement 15 whose mass participates in the inertia of the beam.
  • This reinforcement 15 is shaped into a cell open to further constitute an element receiving body hooking.
  • the side walls of this reinforcement have returns 16 to the outside in order to facilitate gripping primary beams by a user, and more particularly to facilitate their transport and handling on site by the latter.
  • the secondary beams 17 are dimpled, and in particular comprise at minus two superimposed cells 18 and 19.
  • the base cell 18 has straight or curved side walls 20 in the manner of the basic cell 2 of the primary beams 1.
  • This cell of base 18 advantageously comprises at least one conformation profile partially flared up.
  • the side walls 20 which delimit the flare are optionally extended by walls 21 substantially vertical to an upper cell 19.
  • This profile gives the beams secondary 17 stiffness correlated with the structure of the beams primary 1 such that the overall rigidity of the framework in its plane global characteristics of inertia, and therefore of resistance, which are homogeneous for a number of required secondary beams less than that of the frames of the prior art.
  • the side walls 20 of the base cell 18 are joined by a stiffening rib 22 delimiting the flare at their zone median.
  • the base cell 18 has at its bottom wings of stiffening 23 which also forms a support for an end piece 24.
  • the upper cell 19 is open to the outside for the reception of a plank like primary beams 1.
  • This upper cell 19 is parallelepiped, and advantageously has flanges 25 of stiffening along its outer side edges.
  • the secondary beams 17 have on their external lateral faces reliefs 26, in particular streaks, to facilitate their gripping and their manipulation on site by a user.
  • Another aspect of the invention relates to the end caps 24 and 27 of the beams. These are divided into two types respectively assigned to secondary beams 17 and primary beams 1.
  • the point of the dihedral rests against the support wing 28 of the end piece 24 on the secondary beams 17.
  • This support is taken either directly, either through a partition 37, depending on the relationship between the width and height of the suspension member 29 and according to the angle formed by the walls of the dihedral, the latter preferably being of the order of 120 °.
  • FIG. 4 another aspect of the invention relates to the heads of formwork 33.
  • These are preferably each secured to a forestay 41 to facilitate the installation of the structure.
  • These formwork heads 33 comprise a plate 32 movable along the forestay 41 on which it is threaded, and a member 42 for compressing the plate 32.
  • This last 32 has flanges 31 forming the hooking members cooperating with those corresponding 30.40 from any of primary beams 1 and secondary beams 17.
  • the member 42 for setting compression of the plate 32 is shaped like a ramp cross, which takes support on a support member 43 which includes cooperating ramps, secured to the forestay 41.
