Tongue and groove fitted construction components, process for their production and device for forming the tongues and grooves on the components

摘要

A building element (11) manufactured from reinforced porous concrete of groove and tongue type. On the one hand it has a groove (5) of conventional type, and on the other hand a number of tongue-forming apparatuses in the form of bodies (13), whose cross-sectional profile agrees with the cross-sectional profile of the groove, and that have nail devices (14) located eccentrically in relation to the centre of the bodies to allow for adjustment of the position of the body relative to the element (11).IMAGE
