Abstract

Dispositif pour étayer simultanément un poutre et une dalle, les réglages en hauteur étant indépendants. Il comporte une tour d'étaiement télescopique dont les tubes télescopiques 8, réglables de façon continue, étayent la dalle, la poutre étant étayée par des chevêtres 11 qui reposent sur des vérins à vis 13 brochés dans les trous 9 des tubes télescopiques 8. Ce dispositif est utilisable pour la construction de planchers préfabriqués en béton: Le chevêtre étaye la poutre préfabriquée, les tubes télescopiques étayent les prédalles.Device for simultaneously supporting a beam and a slab, the height adjustments being independent. It comprises a telescopic shoring tower whose telescopic tubes 8, continuously adjustable, support the slab, the beam being supported by headers 11 which rest on screw jacks 13 broached in the holes 9 of the telescopic tubes 8. This The device can be used for the construction of precast concrete floors: The header supports the precast beam, the telescopic tubes support the pre-slabs.

Description

À L'invention est relative aux moyens d'étaiement simultanéThe invention relates to simultaneous shoring means

d'une dalle et d'une poutre.a slab and a beam.

On connait également les tours d'étaiement à montants télescopiques (généralement quatre montants) qui étayent la dalle de part et d'autre de la poutrecelle-ci étant étayée par des chevêtres transversaux  Shoring towers with telescopic uprights (generally four uprights) are also known which support the slab on both sides of the beam, which is supported by transverse trimmers.

brochés par leurs extrêmités sur les montants télescopiques de la tour.  pinned by their ends on the telescopic posts of the tower.

Ce dispositif qui présente l'avantage de ne nécéssiter qu'une rangée de tours pour étayer simultanément la dalle et la poutreprésente cependant un inconvénient:Les réglages en hauteur de la poutre et de la dalle ne sont pas indépendants puisque le chevêtre ne peut être réglé que de façon discontinue,étant simplement broché dans les trous des tubes télescopiques. La présente invention a pour objet une tour télescopique et un chevêtre associé réglable de façon continue par rapport à la tour grâce  This device has the advantage of requiring only one row of towers to simultaneously support the slab and beam, however, a disadvantage: The height adjustments of the beam and the slab are not independent since the trimmer can not be adjusted only discontinuously, being simply stuck in the holes of the telescopic tubes. The present invention relates to a telescopic tower and an associated trimmers continuously adjustable relative to the tower through
