Estimating the term…
A process of manufacturing concrete construction elements is provided. A first sheath is placed in a first mold, the first sheath connected at an end to a first sleeve applied against a wall of the mold, the sleeve engaging a positioning boss placed on the wall. Concrete is poured into the first mold and set to obtain the first element. The first element is extracted from the first mold and includes a contact face shaped by the wall. A second sheath is placed in a second mold, the second mold having one side formed by the contact face. The second sheath includes an end connected to a second sleeve held in position relative to the first sleeve by a positioning joint. Concrete is poured into the second mold and set to obtain a second element. The second element is extracted from the second mold by disengaging the positioning joint.
A process of manufacturing concrete construction elements including at least first and second matched elements, the process comprising:
The construction work comprising an assembly of prefabricated elements including at least first and second matched concrete elements having respective first and second contact faces of complementary shape, wherein the first and second matched concrete elements have a plurality of respective pre-stress sheath sections embedded therein, wherein each of said sheath sections embedded in said first element is connected to a respective first sleeve embedded in said first element at the first contact face, wherein each of said sheath sections embedded in said second element is connected to a respective second sleeve embedded in said second element at the second contact face, wherein the first and second contact faces are applied one against the other so that the first and second sheath sections are placed in an extension to one of the other to form complete sheaths, wherein joints are engaged in the sleeves in order to sealingly connect the adjacent sheath sections, and wherein pre-stressing cables and a filling product occupy the interior of the sheaths.
