Abstract

Pilar de acero para soportar un encofrado. Pilar de acero (30) compuesto por un tubo exterior (40), un tubo interior (50), dos elementos de retención (60, 70), un elemento delimitador de la posición (45), un elemento de sujeción (RO), y un elemento elástico (84). El tubo interior (50) se introduce en el tubo exterior (40) de tal modo que el tubo interior puede ser extraído y retraído y el tubo interior extraído es posicionado por el mecanismo de agarre de los elementos de retención (60, 70). El desplazamiento de los elementos de retención es limitado por el elemento delimitador de la posición (45). El elemento de sujeción (80) sirve para enganchar y desenganchar los elementos de retención para poder retraer el tubo exterior extraído. El elemento elástico (84) permite que los elementos de retención (60, 70) se desacoplen del tubo interior.Steel pillar to support a formwork. Steel pillar (30) composed of an outer tube (40), an inner tube (50), two retaining elements (60, 70), a position delimiter element (45), a clamping element (RO), and an elastic element (84). The inner tube (50) is introduced into the outer tube (40) such that the inner tube can be removed and retracted and the inner tube removed is positioned by the gripping mechanism of the retaining elements (60, 70). The displacement of the retention elements is limited by the position delimiter element (45). The fastener (80) serves to engage and disengage the retaining elements in order to retract the extracted outer tube. The elastic element (84) allows the retention elements (60, 70) to be disengaged from the inner tube.
