ELASTIC MINI - FRAMINGS WITH VARIABLE DIAMETER

Amplication of Pneumatic Forme to lighten, while achieving emptiness,  beams for bridges.

Pneumatic Forms to achieve emptiness of lightening

CORVULCA manufacture the hoses used in Pneumatic Form to achieve emptiness in all types of constructions in concrete. These emptiness (hollow) can be circular shape (with diameter from 200 until 4000 mm) or of other shape as one can be seen on the prospectus picture...

Those hoses are inflalte with the compressed air and deflate when it will be necessary to extract it after the concrete become hard. It is especially used, to lighten while creating emptiness, all types of concrete beams achieved in the prefabrication, as well as for bridges, viaducts and so on.
