Definitions

  • the invention relates to a method for manufacturing building blocks, to the means for implementing this method and to the product thus obtained.
  • the building blocks are generally of rectangular parallelepiped shape and each have on at least two of their parallel faces means complementary in shape.
  • one of the faces of the block generally comprises one or more cavities while the face which is parallel to it, has meanwhile according to the same arrangement and preferably, in an identical orientation, ribs and / or complementary bosses.
  • a device is known in particular (patent EP-0027376) particularly suitable for the production of building blocks provided with complementary means. of self-positioning.
  • the imprint of a lower matrix is filled with a predetermined quantity of material in the plastic state.
  • the material is strongly compressed by closing the lower matrix with an upper matrix.
  • each lower and / or upper matrix is profiled to form one of the faces of the block equipped with complementary self-positioning means.
  • the metering device Given the plastic state of the material and its lack of homogeneity, the metering device poses production problems, and therefore increases the cost of the installation.
  • One result which the invention aims to obtain is a process which, by allowing the production of building blocks provided with self-positioning means, guarantees a constant dimension at least between the block faces equipped with complementary self-positioning means. positioning.
  • the subject of the invention is also the means for implementing this process as well as the building blocks thus obtained.
  • the building block 1 is formed by a rectangular parallelepiped of which two parallel faces 2, 3 and preferably, those guaranteeing the most stable support of the block, are provided with complementary means 4, 5 appearing some (4) projecting, the others (5) hollow relative to said faces 2,3.
  • the thickness between the faces 2, 3 provided with complementary means is substantially equal to half the width of the block.
  • the complementary means 4, 5 of the same kind are preferably two in number.
  • the fitted faces 2, 3 have a length substantially equal to twice their width "L" and the complementary means 4, 5 are arranged at the intersection of the diagonals of each of the squares which can therefore be inscribed on each side 2, 3.
  • the complementary means 4, 5 when in the sailie have bosses 7 in the form of a truncated cone which, in a preferred embodiment, have a height substantially equal to one third of the width "L" of the block, angle at the top of about forty degrees and a diameter at the base of about half the width "L" of the block.
  • bosses 7 can have other shapes and for example each be formed of a trunk of a pyramid.
  • the means 5 appearing recessed in the face 3 are preferably of substantially identical shape and, if the blocks 1 are designed to be mounted without a joint, the depth of the cavity which they each form, is at least substantially equal to the boss height.
  • the block it is desirable for the block to have dimensions such that it is manually graspable.
  • the mold 11 comprises at least one cavity 19 in order to form at least one block 1 and, preferably, it comprises several cavities 19.
  • a press 20 which comprises, fixed on its frame 21, a substantially horizontal table 22, the upper face of which constitutes the surface 14 which, in turn, closes the bottom 15 of the lower die 9.
  • a frame 16 rests in which at least one cutout 23 determines the internal side walls 17 which will form the peripheral wall of the block 1.
  • These cores 13 are retractable under the surface 14 and for this they are linked to at least one means of displacement in translation 24.
  • the frame 16 is also secured to a means of displacement in translation 25 which allows, on the one hand, to press it against the table 22 and, on the other hand, to move it away from the latter at least sufficiently to allow the evacuation of a block 1 after it has been placed on a mold release plate 18.
  • the upper matrix 10 is in turn formed of a plate 26, the face 27 facing the table 22 is shaped so as to form the face 2 of the block 1 equipped with bosses 7.
  • the upper matrix 10 is, at least locally, of such dimensions that it can, under the action of a translational displacement means 28 itself connected to the lower matrix 9 close this lower matrix 9 and in particular slide with the 'interior of the frame 16, on the one hand to compress the material and, on the other hand, for in another manufacturing phase, drive the block 1 onto the release plate 18.
  • the mold 11 is equipped with means for controlling and regulating 12 the escape of an excess of material contained in this mold 11 during the compression phase.
  • the means 12 comprises at least one orifice 29 opening into the interior of the mold 11 and of dimensions at least sufficient to allow the passage of the material and, on the other hand, a member 30 making it possible to close this orifice 29 under the control of a means of movement 31.
  • the orifice 29 reserved in the mold 11 is situated substantially in the extension of a cavity 32 intended to form on the block 1 a complementary protruding means 4 and, on the other hand, the member 30 for closing this orifice 29 comes to close it substantially at the top of said complementary means 4.
  • the frame 21 of the press 20 mainly consists of a gantry 33.
  • the frame 16 is in turn secured to a set of at least two columns 34 and 35 connected together, substantially vertical, generally located on either side of this frame and extending substantially over the entire gantry height 33.
  • the translational guide means generally identified at 36 are substantially located at each of the ends of the columns 34, 35.
  • the beam 37 is connected to the frame 21 by a drive means in translation which constitutes the means 25 for moving the frame 16.
  • This means 25 is for example formed by at least one jack.
  • the plate 26 forming the upper matrix is advantageously crossed by the two columns 34, 35 and includes elements 38 for guiding it in translation on these columns 34, 35.
  • the means for translational movement 28 of the plate 21 is for example formed by at least one double-acting cylinder interposed between the beam 37 and said plate 26.
  • the members 30 are generally associated with a plate 40 also crossed by the two columns 34 and 35 and guided in translation thereon by means generally identified at 41.
  • the means 31 for moving the members 30 is for example a double-acting cylinder interposed between the plate 40 and the plate 26.
  • the cores 13 which pass through the table 22 are in turn secured to a plate 42 movable in translation under the action of a motor means 24 which is for example a double-acting cylinder connected to the frame 21.
  • the upper die 10 is equipped with at least one means capable of generating vibrations (not shown).
