Reinforcement for concrete joist in one-way slab, with galvanized steel tubular profiles

Reinforcement for reinforced or prestressed concrete joist in a one-way slab, consisting of a two-component adhesive based on epoxy resin with polysulfides as a bonding bridge, applied with a brush at the base of the joist; an extendable galvanized steel tubular profile with a square cross-section of 100x100x4 mm, fixed to the structure using post-tensioning supports 2 cm from the joist; metal connectors welded to the profile in a staggered pattern and embedded in the base of the joist; and a two-component thixotropic mortar with polyamide fibers placed as filler between the joist and the profile. Includes 10 mm diameter deformed steel bars complying with UNE-EN 10080 B 500 S, for placement in the lap splices of negative reinforcement.
