Hollow block for use in building construction, has vertical embedding units positioning neighboring block between two end positions, and channel formed between one parallel side and external connecting wall

摘要

The block has two parallel sides (11, 12) intended to form faces of a wall. Vertical embedding units (30, 31) permit to position a neighboring block between two end positions. A ventilation wall (13) is placed with respect to the parallel side (11) using an external connecting wall (22), such that a channel (15) is formed between the parallel side (11) and the external connecting wall (22).
