Concrete shuttering with high easily calculated stress resistance - employs hinged couplings connected to cross members with screw fittings

摘要

Concrete shuttering can absorb a high degree of stress exerted in the longitudinal plane of the couplings. It is also possible to calculate easily and exactly the amount of stress which can be absorbed, eliminating the need for allowing large safety margins. The couplings (10) can be progressively attached be progressively attached to the crosspieces (7, 8) of adjacent shuttering elements using screw mechanisms which cooperate with the crosspieces because of an association of forms in the longitudinal direction of the crosspieces. The coupling itself is split into two coupling bars (12) hinged together at a pivot (11) with a screw mechanism attached to one of the bars. The screw mechanism is inserted into the holes in the crosspiece and the coupling and tightened to prevent movement.
