Block Ladder Reinforcements
SFSP ladder and truss types are used for the reinforcement of brick and block masonry to give improved tensile strength to walls subjected to lateral loading e.g. wind and seismic. SFSP block reinforcements reduces the risk of cracking either at stress concentration around opening.
Specifications:
SFSP reinforcement truss type are manufactured by resistance welding of ASTM A82 cold drawn steel wire deformed at predetermined centers conforming to BS 4483:2005.
Dimensions:
- Hot-Dip Galvanized
- Main wire diameter = 4.0 mm 4.8 mm
- Rung and diagonal wire diameter = 4.0 mm 4.8 mm
- Rung wire centers = 400 mm
- Stainless steel AISI 304
- Main wire diameter = 4.0 mm 4.8 mm
- Rung and diagonal wire diameter = 4.0 mm 4.8 mm
- Rung wire centers = 400 mm
The production of cold reduced steel wires complies to BS 4483:2005 and ASTM A951 / A951M - 11 Standard Specification for Steel Wire for Masonry Joint Reinforcement.
- a) Mechanical Properties
- Specified characteristic strength: 460 N/mm2 (Mpa)
- Tensile strength min 510 N/mm2 (Mpa)
- b) Chemical Composition of Steel
- Carbon C max. 0,25 %, Sulphur S:max 0.06 %
- Carbon equivalent value Ceq: max 0.4 %, Ceq=C+Mn/6+ (Cr + V + Mo)/5+ (Cu x Ni)/15
SFSP Block ladder (Ladder type and Truss type) are continuous lengths of joint reinforcement that are embedded into the horizontal joints of masonry walls.
- Block reinforcement offers the following benefits:
- Increases lateral flexural strength.
- Reduces cracking that can arise from thermal stresses.
- Bonds exterior and interior masonry withes together in composite or cavity walls.
- Bonds masonry at intersecting walls and corners.
- Increases performance of masonry wall under various stresses
Bends, Tee-branches, and intersections can be manufactured upon request. Corner units provide continuity y of reinforcement this can be cut and bent on site.
