Abstract

L'invention concerne un coffrage métallique réglable, en particulier pour la construction des tunnels et des galeries ainsi que pour celle des voies et travers-bancs des mines, comportant deux éléments de cintre latéraux raccordés entre eux par une pièce de liaison à position réglable et constituant une surface de coffrage dont le profil peut être modifié. Le coffrage selon l'invention est caractérisé par le fait qu'est prévu un chapeau cintré 3 reposant sur les extrémités, voisines mais éloignées d'une certaine distance, des éléments de cintre latéraux 1, 2, chapeau cintré présentant côté tunnel un dispositif de guidage 4 sensiblement dirigé dans l'axe longitudinal du tunnel, dispositif de guidage équipé d'un système de serrage 31, 32 destiné à appliquer par pression le chapeau cintré 3 contre les éléments de cintre latéraux 1, 2. Application à la construction de tunnels.The invention relates to an adjustable metal formwork, in particular for the construction of tunnels and galleries as well as for that of mine tracks and cross-beds, comprising two lateral arch elements connected to each other by a connecting piece with adjustable position and constituting a formwork surface whose profile can be modified. The formwork according to the invention is characterized by the fact that there is provided a curved cap 3 resting on the ends, neighboring but at a certain distance, of the lateral hanger elements 1, 2, the curved cap having on the tunnel side a device for guiding 4 substantially directed in the longitudinal axis of the tunnel, guiding device equipped with a clamping system 31, 32 intended to apply by pressure the curved cap 3 against the lateral arch elements 1, 2. Application to the construction of tunnels .
