Definitions

  • the invention relates to a building block of the kind which is intended to form part of a vertical wall, a vertical facade or like building structure, and which is bonded to neighbouring building blocks by means of horizontal bed joints and vertical heading joints, and which building block has a channel-like recess, open at both ends thereof, formed in at least one end surface thereof bordering a heading joint.
  • a building block is known from, for example, FR-A-1 330 861.
  • the mortar When building a masonry wall or like structure from building blocks and mortar, the mortar is normally applied manually with the aid of a trowel to that end surface, or header face, of the block which borders a heading joint, and the block is then positioned on the mortar in the bed joint and pushed into position against the end surface of a previously laid block. A satisfactory heading joint is normally obtained, provided that the mortar has been correctly applied.
  • the task of applying mortar is relatively time consuming and therewith expensive.
  • a prime object of the invention is therefore to provide a building block of the aforesaid kind which will enable the use of a pipeable jointing material, hereinafter referred to as mortar, and which eliminates totally, or at least substantially, the risk of excessively large quantities of mortar exiting from the rear side of, for example, a building facade.
  • Figure 1 illustrates a conventional building block 1 made, for example, of burned clay, and a further, identical building block 2.
  • Each of the conventional building blocks has on one end- surface thereof a channel shaped recess 6, which is open at both ends and which is intended to extend vertically.
  • a channel shaped recess 6 which is open at both ends and which is intended to extend vertically.
  • the wall surface of the recess 6 is formed so that the frictional resistance is much greater in a direction towards the rear side 11 than towards the facade side or the front side 10, therewith ensuring that the heading joint is completely filled with mortar in a direction towards the front side 10 before the joint gap towards the rear side 11 is filled and mortar begins to exude, or in all events such that only a negligible amount of mortar exudes on the rear side subsequent to visually establishing that the joint is completely filled on the facade side.
  • This high frictional-resistance towards the rear side results in a large pressure drop and the mortar is thereby guided towards the facade side, where the pressure drop is low, and completely fills the heading joint, i.e.
  • Such a gap 15 forms a barrier which is effective to prevent water penetrating through rearwardly lying insulation.
  • Figure 3 there is illustrated an embodiment of a recess 17, the wall of which is smoothly curved and presents a wall portion 18 of a smaller radius of curvature than the remaining wall portion 19 connecting with or terminating at the front side 10 of the structure.
  • the respective rear side-surfaces 20 and 21 of the illustrated blocks 13 and 14 can be made slightly longer than the respective front side-surfaces 22 and 23, wherewith the free joint gaps on the rear side 11 of the structure will be narrower than the joint gaps on the front side thereof, or in extreme cases will be totally eliminated.
  • Figures 4 and 5 illustrate a modified recess of- which the rear part 24 which produces a high degree of friction is provided with vertical cams or ridges 25, 26, 27 while the wall part 29 which faces the front side of the structure is smooth and creates but small friction, i.e. a low pressure drop.
  • the two portions 24, 28 of the recess wall may have mutually the same radius of curvature, although the radius of the wall portion 24 is preferably smaller than that of the wall portion 28.
