re-bar - Bending reinforcement of reinforced concrete
re-bar is a prestressing steel made of memory steel in form of a ribbed steel bar. The product is an efficient and easy-to-install reinforcement measure, especially for the strengthening of buildings. The material is pre-stretched by re-fer in the factory to a permanent deformation and delivered to the construction site according to the parts list. After roughening the substrate, or after making milling cuts, re-bar is fixed to the concrete. The system-tested mortar is then applied to the anchoring area. After hardening, re-bar is heated to >160°C with re-fer infrared radiant heater and pre-stressed. The area between the anchors is now poured out. The applied ribbed steel acts as an embedded system in the composite.
re-bar:
| Application |
Increase of load capacity
- in the event of live or traffic load increase
- for conversion of buildings
- for changes to the static load-carrying system
- for damaged structural parts
Increase of serciveability
- by reduction of deflections
- by closing or reducing crack widths
Seismic strengthening
- thanks to large ductility
Shear reinforcement
- thanks to overpressing and reducing shear cracks
Schubverstärkung
- dank Überdrücken der Schubrisse
| Advantage |
Prestressing of new or existing reinforced concrete beams and plates
- high tensile strength and ductility
- very good corrosion resistance (CRC 1)
- meets requirements against stress corrosion cracking
- easy handling, fast application
- simple and efficient prestressing
