Device for simultaneously shoring a beam and a slab, the means for vertical adjustment being independent. It comprises a telescopic shoring tower whose telescopic tubes 8 are continuously adjustable and shore the slab, the beam being shored by yokes 11 which rest on screw-jacks 13 supported by pins in the holes 9 of the telescopic tubes 8. This device can be used for the construction of prefabricated concrete floors. The yoke shores the prefabricated beam, while the telescopic tubes shore the shuttering slabs. It can also be used in constructional steelwork. <IMAGE>
