Definitions

  • the movable one of its walls is horizontally displaced from the rest of the panel and mould combination.
  • the panel may then be removed by a lifting device. Afterbeing cleaned the movable mould wall is moved back into its initial position where it is connected to another form or partition which itself is disconnected from its adjacent form or partition freeing a further panel for removal and enabling the pouring of a further paznel without any substantial time delay.
  • the present invention relates to a plant for the manufacture of concrete construction panels by formwork.
  • an apparatus which comprises a plurality of vertical partitions, or forms between which the aggregate is poured possibly after the arrangement of cores or the like in the forming mould and left until sufficient hardening of the concrete, the panels being then removed from the apparatus by means of a travelling crane.
  • a plant for manufacturing concrete construction panels by formwork comprises forms, certain of which advantageously include electric heating means, displaceably mounted alone or in a group, in a direction perpendicular to it or their planes thereby enabling the release of hardened panels and their removal immediately after hardening.
  • the manufacture of various panels is effected in succession in the various pouring spaces allowing non interrupted preparation of the moulds after removal of a panel and thus an optimum use of the manpower.
  • the invention also concerns a form enabling the rapid removal of reinforced concrete panels poured in a bank of formwork so as to increase the yield.
  • this time can be reduced by the heating or baking of the concrete effected by heating forms which advantageously comprises electrical resistors, the said heating forms being distributed throughout the thickness of a bank of formwork comprising a number of smaller or larger pouring spaces.
  • Such a formwork bank may comprise movable forms mounted on rollers and capable of displacement by double-action jacks in order to facilitate the removal and replacement of the bank.
  • the plant according to the invention overcomes these drawbacks by enabling the rapid removal of the cast panels from each side of a form carrier owing to the fact that the form itself is lifted up and not the panels which remain fixed to the form by the peripheral frames which are fixed thereto.
  • the device according to the invention comprises a central plate, interior and peripheral form members corresponding to the panel being temporarily or permanently fixed to each face of said plate.
  • the peripheral form members for the panel comprise in general a lower horizontal section, two vertical sections along the sides, the fourth horizontal side at the upper end remaining free for filling.
  • the central plate comprises at its upper end lifting means, preferably lifting links.
  • the sides are adapted to receive vibrators.
  • the lower portion of the central plate is arranged in such a way that it may rest on supports provided for this effect either in the formwork or outside of the formwork bank and may possibly be displaced on rollers in a plane along the ground.
  • the form carrier device according to the invention When the form carrier device according to the invention is placed in a formwork bank between two forms which, owing to the characteristics of the form carrier may be smooth, comprising no coffering, and the forms are brought together and fixedly maintained relative to one another, it is possible to proceed with the pouring of the concrete into the two gaps or spaces located on either side of the central form previously provided with reinforcements and various inserts desired for the panel to be produced.
  • the form carrier is then removed from a formwork bank and placed where the concrete may age sufficiently for, subsequent removal of the panels by their lifting slings.
  • FIG. 1 is a schematic side view in elevation of a plant according to the invention in the moulding position
  • FIG. 2 is a schematic top view

  • the parallelopiped form is thus delimited by the members 17-20, the plate 22 and fittings 23 on the exterior surface, interposed between the frame members.
  • heating grids 24 comprising snake-shaped resistance heaters 25 with parallel vertical portions 26 (FIG. 4).
  • Reflectors 27 concentrate the heat flux provided by the interior plate 22.
  • the latter is mounted so as to'be freely expandable and contractable by its frictional holding means owing to a flanged member 28 with which it is provided, and through the intermediary of resilient tightening washers 29.
  • Sheets 30 of asbestos are interposed'between the plate 22 and the frame members.
  • a heat insulator 31 such as fibre glass protects the exterior surface and increases the effect of the heating source on the plate 22.
  • Stiffening members 32 are fixed to the plate and their sides are protected by a slab 33 of asbestos.
  • the resistors within the form 16 are supplied with current through a plug 34 (FIG. 1).

  • the plate 41 is detachably connected to the plate 22 by upper and lower latch members 47 and 48 rotatably mounted about vertical pins 49 and 50 which cooperate with pegs 51 and 52 inserted in fittings 53 and 54 fixed to the plate.
  • latch members 47 and 48 rotatably mounted about vertical pins 49 and 50 which cooperate with pegs 51 and 52 inserted in fittings 53 and 54 fixed to the plate.
  • the plate 41 in combination with a plate 55 forming part of an intermediary form 56 provides a second pouring space or mould 57.
  • the intermediary hollow form 56 is of generally parallelopiped shape and comprises in addition to the plate 55 a parallel plate 58 opposite thereto, the frame including frame members 59 (FIG. 7) and cross members 62.
  • Stiffening members 63 and 64 are provided for the plates 58 and 55. With each box-like portion 65 delimited by plates 55 and 58, and frame members 59 and cross members 62, are disposed heating grids 66 carrying snake-shaped resistance heaters 67.
  • the plates 55 and 58 are connected to the frame members by bolts, as shown at 68.
  • the resistors of the various grids are supplied with current by a junction box or electric socket 69 (FIG. 8).
  • Thermostat(s) 70 are provided to cutt off the supply when the plates reach a predetermined temperature.
  • the stiffening members 63, 64 are protected by strips 71 of asbestos (FIG. 9).
