HOW TO EXECUTE A CORRECT OVERLAP?

1. Cut one of the longitudinal wires.

2. The length of overlap for masonry reinforcement should be at least 250 mm and the separation between longitudinal wires ≥ 20 mm

In accordance with the specifications of the current standards, a correct overlap between truss type masonry reinforcement should meet the following requirements: Length of overlap: 250 mm (0,6 the distance of the pitch of the cross-wires). Horizontal distance between overlapped wires: 20 mm.

Lateral coating of the wires that have been cut: 30 mm (except stainless steel wires).

The “plug structure” of the geofor® reinforcement ensures all these requirements without any need for manipulation by the operator.

 

 

IMPORTANT: At the ends of the reinforcement for structural use it must meet the tree requirements: ADHESION, MORTAR COATING and OVERLAP.

 

WHY IS IT IMPERATIVE TO HAVE THE CE MARKING?

Firstly because it is compulsory for the products that are incorporated in the construction of a building. Secondly because the CE marking, carried out within the existing legal framework along with the implementation of the Eurocode are the only quality assurance (of the State not the supplier). It is also the only way of checking that incorporated products in walls have the same benefits stated in calculations. There is no point calculating if there is no comparison value for gauging.

TO IMPROVE THE PERFORMANCE OF MY WALL IN SEISMIC EVENTS,WILL I NEED TO PUT ALOT OF BED JOINT REINFORCEMENT?

For seismic events, the reinforcement itself will improve the mechanical behaviour of the wall because of its ductile properties. However for the same reasons given previously, this cannot be assigned stability of the wall to the reinforcement itself.

 

For the reinforcement to be calculated into seismic effects, it should be accompanied by other elements of retention, such as anchors to the pillars.

DOES THE WIDTH OF THE REINFORCEMENT BENEFICIALLY AFFECT THE STRUCTURAL PERFORMANCE?

Reinforcement used in crack control does not require a specific width, since the only thing that counts in this case is the area of steel section.

By contrast, the width of the reinforcement has a role to play when it has a structural function, and that by increasing the mechanical arm, you increase at the same proportion the horizontal bending strength of the walls in the masonry.
