Floor plate made of reinforced or prestressed concrete for road bridges or the like

摘要

In a floor plate made of reinforced or prestressed concrete for road bridges, the longitudinal and/or transverse reinforcement of the floor panel (4) of the supporting framework consists of reinforcement elements (8, 9, 10) which are protected against corrosion. Arranged above the floor panel (4) is a compensating and wearing course (11) which is directly driven on and consists of a tensionproof and wear-resistant concrete, e.g. fibre concrete, and is connected in a shear-resistant manner to the supporting framework (4) e.g. by a reinforcement mat (12) with rod ends bent out of its plane. The use of corrosion-protected reinforcement elements provides the precondition for foregoing the usual insulation between the wearing course and the supporting framework. This provides the precondition for a material being used as the layer driven on, which is especially suitable for the requirements to be made of it, e.g. steel-fibre concrete. IMAGE
