<p>The detachable connecting system for linking prefabricated elements is esp. applicable to panel-shaped concrete building components, e.g. for walls and ceilings, in houses, garages or hangar type structures. Complementary protrusions or recesses are formed on interfacing element surfaces for joining them together. These can be independent-components, worked into the elements during manufacture, and pref. of greater mechanical rigidity, or they may be moulded with the elements. They can work as tongues and grooves, or claws and hooks. The connection is simple and secure.</p> |
