摘要

Improvements introduced in the removable and extensible metal formwork for concrete pillars, walls and girders, characterized by the use of bolts provided with a transverse groove at their end, in the dihedral angle coupling of the panels or formwork elements, which are they fix projections on one of the edges of the panel in correspondence with some holes of the crosspieces of the armor of the panel; of "U" laminar clamps with pins in the in-line connection of some panels with others; and finally of elongated bars for the connection between each two parallel panels or side shuttering elements, which are provided at one end with a series of recesses for different thicknesses of forging.
