Abstract (en)
The brick consists of one or more sub-blocks (1, 2, 3). Each sub-block is divided into air chambers (4-13) of contained width but extensive in length. The walls (14, 14 min ; 15, 15 min ; 16, 16 min ) which divide each sub-block into chambers are shaped as alternatively concave and convex arcs of a circle. The chambers are connected by septa (17, 18, 19) of minimum length. The sub-blocks are connected by septa (20, 21, 22, 23) also of minimum length and never concident with the periphery of the brick nor placed in correspondence with the inner cores of the successive sub-block, on a line with them. Thermal bridges between the inside and outside of a wall are thus almost completely eliminated, with a brick light in weight, very strong and low in cost.
