Definitions

  • the present invention relates to the manufacture of thin plates or slabs of molded material, in particular of. cement.
  • the invention applies more particularly to the manufacture of cement plates imitating stone for facade cladding or any other use, but it can also be applied to panels or slabs of plaster or other moldable material in the state plastic.
  • EP-A-0051 101 (Odler) plans to drown in a concrete plate a reinforcement constituted by a glass fiber mesh fabric. However, he suggests placing one of two frames at the bottom of the mold and vibrating it up. It is obvious that with this process the position of the reinforcement in the thickness of the plate will be completely random. In this patent, we also seek to maintain the two frames in the vicinity of the upper and lower surfaces of the plate and not to drown them in line with the mid-thickness.
  • DE-A-2854228 proposes to reinforce concrete slabs with glass fiber mats.
  • FR-A-2352665 proposes to drown fiberglass, in particular a mat, in a plasterboard having a thickness not exceeding 5 mm and, according to one embodiment, this mat is applied to the plaster layer and it is made to penetrate by pressure through the dough and up against the molding surface, but no means is described to push such a reinforcement uniformly into a thin plate, but having a thickness sufficient for the sheet to be away from each of the two faces.
  • the object of the invention is to solve these problems of placing a reinforcement with precision in a thin plate of molded material, in particular cement.
  • the process for manufacturing thin molded plates with network reinforcement is characterized in that the reinforcement network is pressed in by a presser forming a plane network of spaced edges .
  • the depth of insertion of the presser into the mass of the plate in the plastic state can be perfectly controlled, the position of the reinforcement, its flatness and the thicknesses of the material on either side thereof , are also perfectly controlled.
  • the reinforcement is constituted by a wide mesh network of crossed wires made of glass fibers, carbon fibers or similar synthetic material. Glass fiber and these other fibers indeed have good mechanical and chemical resistance and the density of the material is such that the reinforcement does not sink naturally, even under vibration, into the mass of cement paste.
  • the mold is vibrated after the insertion of the reinforcement network and after the removal of the presser to restore the flatness of the surface of the molded plate.
  • the installation for implementing the method comprises, in a known manner, a set of molds in the form of the thin plate to be obtained, a unit for preparing in the plastic state and dosing the base material of the thin plate for pour the charge of material prefixed into each mold and to equalize it, for example by vibration, with, in addition and in accordance with the invention, a presser with a plane network of spaced edges whose overall surface corresponds substantially to the surface of the network used to arm the molded plate, a means for lowering at least the edges of the presser in the mold to a controlled level corresponding substantially to the mean plane of the thickness of the plate and a device for subjecting to vibration the mold after removal from the presser.
  • the plate 1 to be produced has a rectangular shape with chamfered edges 2, its dimensions up to 60 x 40 cm with a thickness of 2 cm without these shape and dimensions being limiting. It is made of cement with various aggregates and pigments, it is reinforced by an armature 3 shown only partially in FIG. 1 and it comprises two inserts 4 and 5 made of stainless steel strip having a part embedded in the slab and a part forming a hook 6. The two inserts shown extend parallel to the edges over almost the entire width. plate geur, but they could have any other shape or layout.
  • the frame 3 is constituted by a wide mesh glass fiber fabric.
  • FIG. 3 schematically represents an installation for its implementation.
  • the reference 7 designates a mold in the shape of the plate with a peripheral rim 8.
  • the installation comprises a chain conveyor 9 successively bringing a mold 7 placed at the head of the conveyor at the various stations.
  • a cement paste supply station 11 pours a metered quantity 12 of cement paste into the mold, the metering preferably being carried out by weighing.
  • 13 designates a vibrating station for spreading the load 12 under a constant thickness.
  • a piece of wide mesh glass fabric 3 taken from a 3 'stock or cut on demand is placed on the surface of the dough layer.
  • the frame 3 is embedded in the layer of cement paste and, to do this, the presser 16 shown in more detail in FIG. 4.
  • the presser 16 is constituted by a network of thin blades 17 and 18 arranged perpendicularly with their lower edges in the same plane. These blades are carried by a plate 19 secured to the piston rod 20 of a jack 21.
  • the jack 21 descends the plate 19, the edges of the blades 17 and 18 coming to bear on the frame 3 and pushing it into the layer of dough.
  • This depression can be limited by pressing the edges of the plate 19 on the peripheral rim 8 of the mold 7.
  • the mold can be vibrated to restore the flatness of the upper face, in particular if the reinforced plate does not have no inserts, and we let it set.
  • a frame 26 carrying the inserts 4 and 5 is put in place at station 27 on the mold 7 and, after pressing down forcefully by possible pressing, the mold is vibrated at the station 28, then removed and stored at 29 until the cement sets. After setting, the plate is removed from the mold.
