The present invention corresponds to a formwork mechanism for casting and molding concrete, comprising a coffer having a sheet and four plates arranged around the sheet perimeter. Each plate has holes arranged on its front face. Also, the formwork mechanism includes a structural element, connected to one of the plates by fixing means. On the other hand, the structural element has lateral perforations that are aligned with the holes of one of the coffer plates. Fixing means pass through the holes and side holes. The structural element may be a beam, a three or four-beam T, and combinations thereof. On the other hand, using several coffers interconnected with structural elements, formworks are constructed for casting flat reticular slabs; and also for curved reticular slabs with greater slab thickness near the beams supporting the slabs in comparison to the span of the slabs. 1. A formwork mechanism comprising:{'b': 1', '2', '3', '2', '3', '5, 'a coffer () composed of a sheet () and a plate () arranged around the perimeter of the sheet (), the plate () having holes () arranged on its front face; and'}{'b': 4', '3', '7', '4', '9', '5', '1', '3, 'a structural element () connected to the plate () with fixing means (), the structural element () having lateral perforations () aligned with the holes () of the coffer () plate ();'}{'b': 7', '5', '9, 'where the fixing means () pass through the holes () and the lateral perforations ().'}2123235. The mechanism of claim 1 , where the coffer () comprises a sheet () and four plates () arranged around the sheet perimeter () claim 1 , each plate () having holes () arranged on its front face.31. The mechanism of claim 2 , characterized by the coffer () comprising:{'b': 17', '2, 'punctured tabs () located on the sheet periphery ();'}{'b': 6', '3', '6', '3', '17', '2', '7, 'punctured tabs () located on the periphery of each plate (), where a punctured tab () from each plate () is connected to a punctured tab () of the plate () by ...
