De modo esencial, el encofrado recuperable
objeto de la presente invención comprende paneles de encofrado que
se apoyan en vigas especiales dotadas de bordes salientes de
retención, por ejemplo, bordes almenados en su parte superior, que
son susceptibles de retener los bordes de los paneles de encofrado y
de sostener a éstos en suspensión en la fase final del desmontaje,
colgados de dichos bordes de retención, a la vez que las
mencionadas vigas quedan incorporadas mediante ejes extremos de
articulación en sendos cabezales portadores de juegos de ganchos
desplazables verticalmente, incorporados en los pies derechos. Con
esta disposición se posibilita que los ganchos receptores de las
vigas tengan una posición alta de trabajo en la que los paneles de
encofrado están dispuestos a la altura de trabajo y otra posición
más baja en la que, al descender los mencionados ganchos, se
posibilita el desprendimiento del panel con respecto al forjado de
piso y su posterior corrimiento transversal para permitir su
basculación y suspensión de una de las vigas mencionadas. El
desplazamiento vertical de los ganchos se efectúa preferentemente
por un sistema de cuñas, de modo que su accionamiento resulta muy
fácil por la simple introducción en la cuña o liberación de la misma
de su posición de
trabajo.Essentially, the recoverable formwork object of the present invention comprises formwork panels that are supported by special beams provided with protruding retaining edges, for example, crenellated edges in their upper part, which are capable of retaining the edges of the panels of formwork and to support them in suspension in the final phase of disassembly, hanging from said retaining edges, at the same time that the mentioned beams are incorporated by means of extreme articulation axes in two heads carrying vertically movable hook sets, incorporated in the right feet. With this arrangement it is possible that the receiving hooks of the beams have a high working position in which the formwork panels are arranged at the working height and another lower position in which, when the said hooks descend, the detachment of the panel with respect to the floor slab and its subsequent transverse sliding to allow its tilting and suspension of one of the mentioned beams. The vertical displacement of the hooks is preferably carried out by a wedge system, so that its operation is very easy by simply introducing or releasing the wedge from its position of
job.
