Definitions

  • the present invention relates to a formwork for an end seal of a molded wall panel, and more particularly to such a formwork comprising a sole and a box mounted on said sole.
  • the trench is generally dug under bentonite mud. Once the trench has been dug, a formwork is immersed in the mud which is placed at the end of the trench.
  • Document CH-A-665241 discloses a formwork of the aforementioned type produced in several parts arranged to be connected longitudinally one after the other.
  • the object of the present invention is to improve this arrangement.
  • the subject of the invention is a formwork for an end seal of a molded wall panel, comprising a sole and a box mounted on said sole, and the cross section of which has a longitudinal slot for the insertion of the seal, the formwork being produced in at least two parts arranged to be connected longitudinally one after the other by means of connecting members (see CH-A-665241), characterized in that the end of the box of each of the parts is set back relative to the corresponding end of the sole, and that the connecting members are constituted by a connecting piece having substantially the same cross section as said box and connectable to the respective soles of each of said parts , by being inserted in the zone of interruption of the boxes so as to overlap the end zones of the soles.
  • connection system between the two parts of the formwork allows excellent alignment and good rigidity of the assembly.
  • this connection system does not introduce any excess thickness of the formwork which could make its extraction more difficult.
  • the connecting piece comprises at least two holes located opposite holes formed in the ends of the flanges for the passage of connecting pins.
  • This arrangement makes it possible to perfectly transmit the vertical forces between the different parts of the formwork during its vertical extraction.
  • the connecting piece can for example be fixedly mounted at the end of one of the flanges from which it projects, and include connection means with the end of the other flange.
  • the box can be made in the form of two half-boxes separated by a longitudinal slot allowing in particular the insertion of a seal, the connecting piece being formed of two corresponding half-pieces.
  • the box from its lower part may also have a transverse dimension which decreases towards its free end over at least part of its height.
  • the upper part of the formwork shown in FIG. 1 is formed by a sole 1 on which are welded two half-boxes 2 separated by a longitudinal groove 3.
  • the half-boxes 2 are interrupted in the top 4 and bottom 5 end zones of the sole 1.
  • the sole forms two holes 6, the axes of which are in the same horizontal plane while in its upper part 4 of interruption of the caissons, it forms two holes 7 substantially of the same diameter as the holes 6 and the axes of which are also in the same horizontal plane, as well as four holes 8 of smaller diameter respectively located above and below each of the holes 7.
  • Two connecting half-pieces 9 of the same cross section as the boxes 2 are fixed in the lower part 5 of the boxes interruption, on the one hand by welds 10 ensuring their positioning, and on the other hand using each an axis 11 engaged both in a hole 6 and in a corresponding hole 12 of the connecting half-piece.
  • Each connecting half-piece protrudes from the lower edge of the sole 1 and comprises in this zone a second large-diameter hole 13 in which a connecting pin 14 is fixed, and two smaller diameter holes 15 respectively above and at - below hole 13.
  • the lower part of the formwork shown in FIG. 2 comprises a sole 1 ′ on which are fixed two half-boxes 2 ′ forming between them a longitudinal groove 3 ′.
  • the boxes 2 ′ are interrupted in the upper zone 4 ′ of the sole 1 ′, this upper zone comprising holes 7 ′ and 8 ′ similar to the holes 7 and 8 of the sole 1.
  • each half-box has a transverse dimension which gradually decreases in the lower part of the formwork, these two half-boxes ending in a bevel by inclined planes 20.
  • connection between the upper and lower parts of the formwork is made by engaging the connecting pins 14 fixed to the connecting pieces 9 in the holes 7 ′ of the base 1 ′, then by screwing bolts 21 in the holes 15 and 8 ′ opposite.
  • the bolts 21 essentially serve to ensure the transverse assembly of the two parts of the formwork while the vertical extraction forces are transmitted by the axes 11 and 14.
  • tall elements of FIG. 1 can in fact be added one after the other, their holes 7 and 8 being able to be used either for their connection to another section, or for their attachment to a lifting machine.
