Definitions

  • Modular formwork systems of this kind generally have the advantages of being able to be set up quickly, with great ease, and of being able to be laid down, just as easily and quickly.
  • Such a device has very significant drawbacks and in particular a reduced solidity due to the fact that the primary beams are only hung on a plate of the falling heads of the props, which can also deform or crack before breaking.
  • a first object of the invention is to remedy the aforementioned drawbacks.
  • this objective is achieved by means of a modular bearing system of the aforementioned kind remarkable by the fact that the drooping head of the props is provided with a support console arranged above and at a distance from the attachment plate of said drooping head, and by the fact that the attachment ends of the primary beams comprise, above and at a distance from their attachment lug (s), a boss having a lower bearing surface intended to rest on said support console for the hanging head of the props.
  • the primary beams can be placed in double support on the drooping heads of the props.
  • the fixed column of the propping heads has a stop plate disposed below the fixed upper plate of said props and above the support console, this stop plate s' opposing the untimely lifting of the primary beams hung on the drooping head when the latter found in high position.
  • the primary beams 3 and the secondary beams 4 are shaped or arranged in such a way that when the first ones are hung on the heads 2 of the props 1 and the second hung, by means of their hooking ends 5, on the side of the primary beams 3, the upper horizontal surfaces S of said secondary beams 4 are arranged in a plane PP located at a distance and above the plane P'-P 'in which are placed the upper surfaces S' of said primary beams 3.
  • the formwork skin or formwork surface 33 which may consist of a sheet of plywood having the desired thickness, is placed on the upper face S of the secondary beams 4, so that a space d is formed below said formwork skin 33, between the planes PP and P'-P 'in which the upper faces S and S' of the secondary 4 and primary 3 beams are respectively arranged.
  • the beams 3 and 4 may advantageously be constituted by metal profiles such as aluminum profiles comprising, in a manner known per se, an upper groove in which is housed a fur 6 constituted by a wooden cleat and a lower groove 7 allowing in particular the attachment of various devices or devices necessary for construction.
  • metal profiles such as aluminum profiles comprising, in a manner known per se, an upper groove in which is housed a fur 6 constituted by a wooden cleat and a lower groove 7 allowing in particular the attachment of various devices or devices necessary for construction.
  • These beams 3 comprise, in their lower part and on each of their sides, a fin 8 inclined towards the outside and in the direction of the top, this fin extending over the entire length of said beams and delimiting a gutter or longitudinal groove 9.
  • the secondary beams 4 may be different from the primary beams 3.
  • the fixed column 16 has at its upper part, two superimposed horizontal plates 19, 20 distant from each other.
  • the upper plate 19 is intended to support the formwork skin 33, while that the lower plate 20 constitutes a stop opposing the accidental lifting of the primary beams 3 hung on the drop head, when the movable element of the latter is in the high position.
  • the column 16 has, in its lower part, two longitudinal columns 21 diametrically opposite and on the top of which rests the cam 18 when the movable support 17 is immobilized in the high position.
  • the mobile support 17 comprises, on the one hand, near its lower end, a hooking plate 22 for hooking the ends 5 of primary beams 3 and, on the other hand share, at its upper part, a support console 23 disposed above and at a distance from said attachment plate, this console constituting, for example, the top of said mobile support.
  • the attachment plate 22 has a rim 24 inclined towards the outside and delimiting a peripheral groove 22a in the form of a quadrilateral, the degree of inclination of this rim being substantially the same as that of the lateral fins 8 of the beams 3.
  • D ' the other hand, the distance D4 which separates the rim 24 and the bearing surface of the support console 23, is substantially equal to the distance D3 comprised between the latching pins 10 and the base 11a of the support bosses 11 of the primary beams 3.
  • the descending cam 18 of the falling heads comprises a body 25 provided with a circular central opening 26 communicating with two lateral notches 27 diametrically opposite and dimensioned to allow the passage of the supporting and guiding columns 21.
  • the descending cam present on its underside, two planar surfaces 28 diametrically opposite, allowing its support on the top of the columns 21 and helical sloping surfaces 29 connecting said planar surfaces 28 to the notches 27.
  • the cam cam includes two diametrically opposed levers 30, allowing its operation.
  • the mobile support 17 is held in the high position by the cam 18 which rests on the top of the columns 21, by means of its bearing surfaces 28.
  • the mobile support is lowered by turning the cam 18 over 90 degrees, so as to bring its notches 27 above the posts 21 which serve as guides to said cam, when the latter falls and when it rises to the locked position.
  • FIG. 14 There is shown in Figure 14, the establishment of a primary beam 3. It is first hung, by means of the latching lugs 10 of one of its ends 5, on the attachment plate 22 of the drooping head 2 of a forestay 1, then lifted in a horizontal position and hung, by means of its opposite butt, on the drooping head of a second forestay arranged in alignment with the first. In this position (FIG. 13), the latching lugs 10 of the primary beam 3 are housed in the groove 22a of the latching plate 22, while its support boss 11 rests on the upper face of the console support 23. This double bond ensures stable and solid positioning of the primary beams on the falling heads of the props.
  • the upper fixed plate 19 intended to support the formwork skin 33 provides protection for the underlying fixed plate 20 in the event of the forestay falling, this result having its importance since a deformation of the plate fixed stop, even reduced, may render said stay unusable.
  • each end of the primary beams 3 has, in its lower part, a chamfer 31 disposed behind and close to the hooking nozzles 10, and the inclination of which is reversed relative to the inclination of the fins 8 and ledges 24.
