Building block of the hollow asymmetric block type comprising, in particular, on two of its dimensions contiguous a raised which ensures the figures of the para - seismic a space between two walls, the nesting and the self - alignment.

摘要

The invention relates to a construction block. The block of artificial stone comprises, on its outer face for longitudinal alignment, an oblique parallelepiped (4) offset downwards and offset laterally, and at the level of the ends of the said oblique parallelepiped there is a half-hole for decompression (9A, 9B) which, at the lap joint of the blocks, ensures the removal of water and dust on the heel (5). Each lateral face (2) comprises a setback "A". The said setback "A" corresponds to the length of the earthquake-resistant space "A" between two walls. Construction block for building comprising one or two levels constructed to earthquake-resistant standards. IMAGE
