  • the subject of the present invention is a method of molding a building block constituted by a plate from which projecting elements are perpendicular or not, this method consisting in installing a mold with pivoting walls, at a location where said block must be permanently installed; lifting the mold cavity from the mold relative to a transport frame for this mold; unfolding and blocking said pivoting walls so as to form the molding cavity delimiting the contour of the plate and of the bearing elements of the block; optionally adjusting, in at least one horizontal and vertical direction, said mold cavity relative to the transport frame; pouring a molding material, for example concrete, into the molding cavity; folding the pivoting walls back to their initial position to release the plate and the load-bearing elements of the solidified block; to lower the mold cavity to detach it from the solidified block; and extracting the mold from the solidified block by passage between the load-bearing elements of said block.
  • the walls are unfolded along a substantially horizontal axis to form the plate of the block, and the pivoting walls are unfolded along a substantially vertical axis to bring them closer to one another in order to define in the molding cavity part of this cavity which delimits the bearing elements of the block.
  • This method is further characterized in that, after extraction of the mold from the solidified building block, the mold is juxtaposed with this block so that at least two walls pivoting along the above-mentioned substantially vertical axis enclose at least one of the carrier elements of said previously solidified block, then a second building block is molded adjacent to the first and having at least one common carrier element with the first block.
  • the invention also relates to a molding device for implementing the method meeting the above characteristics, this device being constituted by a transportable mold comprising a molding cavity with articulated walls and means of transport and positioning of the mold relative to the ground.

  • the mold 1 is moved using the wheels 22 and 23, the walls of which are closed in the transport position up to the location S of the building, represented by dotted lines, where the building block B will be molded
  • this location S is located on an already existing construction, such as for example another solidified building block B.
  • a foundation such as a concrete slab or a foundation under each vertical support element at the location S chosen to rest the building block that we want to mold.
  • the crutches 24 are placed so as to stabilize the mold 1 relative to the ground, as is sees well in Figure 5, and thus avoid unwanted movement during subsequent molding operations.
  • the first walls placed in the molding position are the flaps 3a and 3b. To achieve this, these flaps are raised to a substantially horizontal position using jacks 6a and 6b ( Figure 1) which also block the flaps.
  • the four double walls 7a, 7b forming the lower part of the cavity 2 and serving to mold the support elements E of the building block B are then unfolded as seen in FIG. 7 in the molding position.
  • the outer flaps 7a are pivoted about the axes 8 from their folded position against the ends of the chassis 5 to a position of coincidence with the flaps 3a and 3b.
  • the interior flaps 7b are pivoted about their axes 8 from their folded position between the frame 5 to a position of contact with the exterior flaps to define with them a molding space communicating with the upper part of the molding cavity 2 and allowing the molding in a single block of the support elements E and of the plate P of the block.

  • the lifting operation is carried out by deforming, using a crank (not shown), the compasses constituted by the articulated arms 13 in the direction indicated by the arrows H in FIG. 8.
  • the carriages 14 and 18 are immobilized relative to the base 21 of the chassis 5 using, for example, brakes (not shown) blocking the rotation of the rollers 16 and 19.

  • it is essential to lower the cavity 2 by a height such that the wall 3 and the flaps 3a and 3b are lower than the lower part of the ribs of the plate P resulting from the molding of the concrete in the grooves 10.
  • the mold 1 is extracted by rolling it between the bearing elements E of the block of construction B.
  • a building block B which alone can constitute the framework of a building such as, for example, a detached house, it being understood that it will suffice to closing, with prefabricated elements for example, the lateral openings delimited by the load-bearing elements E.

  • the mold 1 is juxtaposed with a building block B previously molded.
  • the procedure for adjusting the position of the mold cavity 2 relative to the frame 5 is carried out in the same way as described above, so as to place the mold cavity 2 in a position such that one can enclose one of the carrier elements E of the building block B already solidified between the exterior flaps 7a and interior 7b of one of the double walls 7a, 7b.
  • the different walls of the mold 1 are then installed in the molding position as illustrated in FIGS. 4 to 7.

  • each seat forming an air cushion can be fixed permanently or removably to the chassis 5.
  • each seat forming an air cushion 40 is constituted by a plate 42 under which a skirt 43 is fixed.
  • the skirt 43 rests itself on a support plane of the mold 1, such as for example the ground.
  • a flexible pipe 44 for supplying compressed air is fixed on the plate 42 and communicates with a chamber 45 formed in this plate.

  • Each support plate 42 is articulated on the frame 30 by means of a ball-joint element 50.
  • This element 50 comprises an upright 51 or the like, which is fixed, for example by welding, to the frame 30, and which extends substantially vertically from the lower part thereof. It will be specified here that the seats forming air cushions can also be detachably fixed to the chassis 5.
  • the lower end of the upright 51 has the shape of a hemisphere 52 which is connected to the upright by a portion of reduced section 53.
  • a housing 41 is mounted with clearance on the upright 51 at the portion of reduced section 53 which passes through a bore 41b of the upper wall 41a of the housing 41.
  • the hemisphere 52 can come into contact with the lower wall 41c of the housing, thanks to the mounting clearance of the part 53 in the bore 51b.
  • the lower wall 41c of the housing is fixed to the support plate 42 to thereby produce a swiveling connection.
  • the air cushion 40 can automatically adapt to the irregularities of the surface on which the mold 1 rests to facilitate its movement, as for example in the case where it is desired to move the mold on an inclined plane. It is thus possible to avoid any recourse to an additional displacement system such as a crane, when it is desired to load the mold on a vehicle for example.
  • the mold 1 is equipped with four seats forming air cushions 40 arranged in the vicinity of the four corners of the frame 30, which is for example rectangular.
  • Each air cushion 40 is connected, by through its supply line 44 to a pressure distributor 60.
  • the pressure distributor 60 is itself connected by a flexible conduit 61 to an internal compressor shown schematically at 70 in FIG. 17.
  • This compressed air supply system has two main advantages. First of all thanks to the distributor 60, it is possible to balance the pressures in the air cushions 40 to give the chassis 5 perfect stability. Then, it is possible to use a compressor of the type of those commonly used on construction sites, this compressor can also be used for other purposes than feeding the air cushions, for example to vibrate the material to be molded.
  • this block can have a polygonal or other shape and include supporting elements E perpendicular or not at the P stage of the block.
