Definitions

  • the present invention relates to a method and means for constructing masonry walls of prefabricated cementitious blocks.
  • the method currently used to construct masonry walls of cementitious blocks is based essentially on exhausting slow manual work.
  • the (qualified) bricklayer applies to the upper face of a horizontal succession of blocks relatively thick runs of mortar along two sides of the blocks, which have already received a layer of mortar applied to one of their lateral faces to obtain a lateral bond between one block and the next.
  • the bricklayer places on the resultant row of blocks a row of blocks offset from the underlying row, this operation involving:
  • the main object of the present invention is to provide a method and means which represent an innovation compared with the aforedescribed method and enable:
  • the cementitious blocks 1 with which a wall is to be erected are widely known and standardized; they are similar in shape to a right (rectangular) parallelepiped having two parallel through holes 2, 3 for lightening purposes separated by an intermediate internal wall 4.
  • the holes are conical or tapered.
  • a row of blocks 1 with their minor faces side by side is laid on a predisposed cementitious bed or similar cementitious surface. This row of blocks forms the base from which the wall is erected by superposing rows of mutually offset blocks.
  • a spacer/centering element D (described in detail hereinafter) is positioned on the base blocks, i.e. the blocks of the lower row, in correspondence with the openings of each of their holes 2, 3.
  • This spacer/centering element D of annular shape (moulded in plastic material, for example filled polypropylene made fireproof) comprises, preferably peripherally and/or in proximity to the periphery, support feet 5 for example of cylindrical or pin shape, which rest along the contour of these openings, these latter having rectilinear sides connected together by arcuate corners (see Figure 5).
  • the spacer/centering element D also presents (in this example) on one side ( Figure 1) a first peripheral skirt 6 which follows the contour of the hole in the block and enters the hole itself (via said opening). In this manner the spacer/centering element D rests on and is centered about the underlying block.
  • a nozzle 8 is provided having a wide and narrow exit mouth 9 (similar to the interspaces) and fed with mortar from a vessel 10 by means of a screw feeder 13; the feed can be controlled by a valve (not shown).
  • a profiled smoother bar 11 is provided to the side of the nozzle 8 to the side of the nozzle 8 to the side of the nozzle 8 to the side of the nozzle 8 to the side of the nozzle 8 there is provided a profiled smoother bar 11 with which the external face of the injected mortar layer is finished.
  • the skirts 6, 7 of the spacer/centering element D comprise rounded corner portions 6a, 7a with a tapered lead-in end to provide effective centering, and intermediate parts 6b, 7b of undulated shape.
  • the undulations form channels 13 ( Figure 6) through which the mortar also reaches the sides of these holes, to give rise to the formation of inward projections when the mortar has set.
  • the injected mortar solidifies to replace the support feet 5 for the static support of the wall.
  • the wall erection can be continued until completion by proceeding in the aforedescribed manner.
  • the undulations can be dispensed with, the centering function being entrusted to only the corner portions 6a, 6b.
  • the spacer/centering element D defines an aperture A to enable possible passage of reinforcing rods for constructing pillars obtainable, as in the known art, by casting cementitious mortar into the holes 2, 3 of the blocks, which are virtually superposed in the erected wall.
