A wall construction includes a plurality of shaped bricks for dry attachment to one another. Each said brick has a first bearing surface which includes a groove formed with a recess, and a second bearing surface in substantially parallel relationship to the first bearing surface and provided with a key which is formed with a projection, wherein the projection and the recess are complementarily shaped and positioned such that the projection of a first brick is engageable with the recess of a second brick when the second brick is stacked on the first brick for restraining displacement in a longitudinal direction of the second brick relative to the first brick. The bricks are formed with chases extending perpendicular to the first and second bearing surfaces and including a central channel and semitubular channels formed at opposing end faces of the brick.
A wall construction, comprising a plurality of shaped bricks joined in dry construction to one another, each brick having a first bearing surface which is provided with a groove formed laterally with a lateral recess, and a second bearing surface which is provided with a key formed laterally with a lateral projection, with the projection and the recess being complementarily shaped and positioned such that the projection on a first brick is engageable with the recess of a second brick when the second brick is stacked on the first brick for restraining displacement in a longitudinal direction of the second brick relative to the first brick, said brick being formed with chases extending perpendicular to the first and second bearing surfaces and including a central channel and semitubular channels at opposing end faces.
