摘要

The hollow shuttering block is a rectangular parallelepiped in shape divided into two parts (2, 3) each of which is a square parallelepiped. The two parts are joined by an intermediate hollow compartment (4) with two vertical walls (5) as extensions of the sides of the two parts (2, 3). The intermediate compartment (4) has a middle vertical ridge (9). The hollow part (3) is in the shape of a hollow cube open on one side, with a top covering. The other hollow part has partitions (11). The sides of parts (2, 3) have a truncated-cone shape. The bottom wall of the top cover is semi-circular. The transverse end of the partitioned part (2) has a female groove (14).
