Definitions

  • the present invention essentially relates to a process for manufacturing composite building elements, as well as an installation for implementing this process.
  • Building blocks or concrete blocks made up of two layers or strata made of different materials have already been proposed in the building, and which are manufactured with a mold into which two materials of different compositions are successively introduced so as to obtain, after demolding, a block to two layers of different materials.
  • German publication DE-A7-2 900 939 there is described a process for molding concrete blocks which consists in introducing into a mold two successive layers of material and then depositing above these two layers , that is to say above the molded block, a plate, after which the mold is subjected to a rotation of 180 ° so that the plate constitutes a support for the molded block which can thus be transported.
  • the molding of the two layers or strata forming the block is carried out in a single step, that is to say by simply filling the mold with a first material and then with a second material.
  • a separate treatment or molding of the two layers of the block is not carried out here, so that the latter, once molded and finished, does not have the required qualities of homogeneity and resistance.
  • the object of the present invention is therefore to remedy these drawbacks by proposing a method and an installation which allow a rational, rapid and inexpensive manufacture of composite blocks with several layers, which exhibit remarkable homogeneity and resistance and which can be used for the construction of any buildings or works.
  • the subject of the invention is a process for manufacturing composite construction elements forming for example parallelepipedic blocks or concrete blocks and of the type consisting in filling at least one mold with at least two materials of different compositions successively introduced into this mold. so as to obtain, after demolding, a block with two layers or layers of different materials, characterized in that before introducing a first material into the mold, a plate is placed across and inside the molding space or the like onto which this material falls so as to mold a layer of the block between this plate and the open upper part of the mold, then said plate is retracted from the interior molding space to cause said layer to descend by gravity in the bottom of the mold, after which another material is introduced into the remaining space of the mold to form another molded layer between the upper part of the first re stratum and mold.
  • the method of the invention makes it possible to perfectly master the manufacture of the block by separate molding, in a way, of the various layers of the block in the same mold, so that in total, the finished block will always excellent and invariable qualities from one block to another, which was not the case with the methods of the prior art.
  • the invention also relates to an installation for implementing the above method and of the type comprising at least one mold capable of receiving a plate or the like and which is associated with means for filling said mold with different materials, characterized in that that said plate is arranged between the upper part and the bottom of the mold to form a removable transverse partition in the interior space of said mold.
  • a light is provided in at least one of the side walls of the mold to allow the guide and the sliding of the aforementioned plate.
  • an installation according to the invention for manufacturing composite building blocks, essentially comprises a tray or table 1 equipped with a plurality of molds such as 2, whose open upper part 3 is flush with the table 1.
  • the molds 2 can be an integral part of the table 1 or else constitute removable elements embedded in the openings provided in said table 1.
  • the molds 2 have a generally substantially parallelepiped shape, but could very well have any other form without departing from the scope of the invention.
  • Each mold 2 is equipped with a plate or the like 4 arranged transversely in the interior space of the mold 2, as seen in FIG. 1.
  • the plate 4 can be actuated by any suitable means, such as for example a double-acting cylinder 5 of which the body has been shown at 6 and at 7 the rod connected at 8 to the plate 4, so that the latter can operate somewhat in the manner of a drawer capable of producing or not a transverse partition inside the mold 2.
  • a light 9 allowing the guide and the sliding of the plate 4.
  • the mold 2 has a removable bottom constituted by a support 10 allowing the evacuation of the building blocks after molding, as will be explained later.
  • a container or container 11, 12 is provided on the table 1, and on either side of the opening 3 of the mold 2, a container or container 11, 12 is provided.
  • the containers 11, 12 each contain a different material based on concrete and can slide by their bottoms 11a, 12a on table 1, as can be understood with reference to FIG. 1.
  • These bottom walls 11a and 12a comprise respectively, and as best seen in FIG. 2, an opening 13,14 whose dimensions correspond substantially to the open upper part 3 of the mold 2.
  • Each container 11, 12 can be actuated by a double-acting cylinder 15 which thus allows either to push the containers above the open upper part 3 of the mold 2, or to move them away from the part 3 of the mold, and this in sliding on the table 1, as will be explained later in detail about the operation.
  • a press arranged above the table 1 and in line with the filling opening 3 of the molds 2, said press making it possible to press the materials contained in the mold 2 at the end of the molding operation .
  • the tanks 11 and 12 are supplied by suitable means and not shown (hopper for example) with different construction materials.
  • one of the tanks, for example tank 11 may contain traditional concrete
  • the other tank 12 may contain a specific concrete, for example concrete lightened by suitable loads and such as for example expanded clay, glass beads or the like.
  • the drawer or the plate 4 of the mold 2 is placed across the said mold using the jack 5, as can be seen in FIG. 1.
  • the tank 11 is pushed by the jack 15 above the opening 3 of the mold, so that its content pours out through the opening 13 to fall on the plate or drawer 4 which, in this case, constitutes a bottom .
  • the filling of the part 2a of the mold 2 can be carried out up to the level of its upper part 3, and, in doing so, the tray 11 is made to move back and forth using the jack 15 so as to level the concrete flush with the surface of the table 1.
  • the concrete in the compartment 2a of the mold can be, at this stage, compacted using the vibrating device 16.
  • the container 11 is removed and takes the position visible in FIG. 1 so as to be filled up again, and, by means of the jack 5, the drawer is opened by removing the plate 4, which causes gravity to descend into the part of bottom 2b of the mold, the molded concrete which was originally in the part 2a, and which will form the lower stratum 32 of the block 30. It may still be useful at this stage to vibrate the mold 2 again to promote compaction in mold base. Then, the other tray 12 is brought above the mold and the same operations as those described above with respect to the tray 11, are carried out. In short, the material contained in the container 12 pours into the remaining molding space 2a, and this material is leveled back and forth from the container 12 on the table 1, so as to produce the upper layer 31 of the block 30.
  • the press 22 is then actuated to compact the two layers filling the mold 2, and this possibly using the vibrating device 16.
  • the press 22 is then raised and, for demolding, or lifts the table 1 using the jacks 17, or the support 10 is lowered using the jacks 19, or else the lifting movements and d aforementioned lowering.
  • the composite blocks 30 with two layers according to the example considered are placed on the support 10 which constitutes a sort of removable base for the mold 2, and the blocks 30 are evacuated to a storage place or directly to steaming.
  • a new support 10 is placed under the row of molds 2 so as to manufacture, as explained above, a new series of blocks.
  • the method of the invention makes it possible to produce blocks with more than two layers, without departing from the scope of the invention.
  • the control of the jacks 15, of the jacks 17 and 19, and even of the jack 6 can be automatic, all these jacks being able to be synchronized so that the installation according to the invention can operate automatically.
  • the press 22 can be controlled by any suitable means and the design, shape and dimensions of tanks 11 and 12 and of the mold 2 can be any without departing from the scope of the invention. It is therefore possible to manufacture, by the process and installation of the invention, composite building blocks with several layers, at a high rate, a low production cost and a constant quality of the finished products.
