Abstract (en)
The terracotta breezeblock is constituted by an enclosure (2) with vertical walls, partially closed on the top . There are two vertical external faces (4) opposite to the walls each having a rectangular facing (4a) having a hollow rectangular joint (5) on one vertical and one horizontal edge. The other vertical and horizontal edges of the facing are coincident with the horizontal (4d) and vertical (4e) edges of the vertical face. The upper horizontal face (6) of the enclosure has a rectangular opening (6a) edged by a relief moulding. This moulding is interrupted on each of the opening large sides to form a transverse groove (6c) centred on the opening. Each of the large external vertical faces are separated from each other by a first vertical portion (5a) of the hollow joint. This portion is extended along the upper horizontal edge (4b) of the face by a portion (5b) and along the vertical edges (4c) of the same face by a second vertical portion (5c). The terracotta blocks can be easily laid by an amateur, the lateral and longitudinal alignment being automatically assured by relief guide mouldings on their upper surface which engage in the lower edges of blocks in an upper row.
