Abstract

Improvements in the shuttering system of tubular pieces of concrete, characterized by comprising a countermold or male, removable by relative lateral displacement with respect to the molded piece, whose counter-mold consists of a core formed by a prismatic piece of trapezoidal section that is located in longitudinal position resting on the plate or bottom of the mold and is complemented by cores or elements attached to its sides, fixed in their exact position by couplings formed by supports at the ends, steps, projections or recesses, so that together with the core they constitute the countermold corresponding to the cavity of the element to be formed, whose movable elements always have lateral dimensions less than the width of the base of the trapezoidal prismatic core, so that once the concrete piece has been set and the core removed, these elements can be removed by displacement lateral through the opening of the concavity formed by them in the concrete piece made (Machine-translation by Google Translate, not legally binding)
