. 3 10M stirrups are required at a maximum d2 spacing for spans greater than 1 200 mm where d is the distance from the top of the lintel to the level of the bottom reinforcing bar in the lintel. All our testing is done by Labco Civil Engineering Materials Testing Services Pty Ltd an ISOIEC 17025 Accredited laboratory. Lintels are manufactured to an actual height of 7-58 inches to coincide with the typical course height of concrete masonry.

Additionally if lintels are subjected to tensile stresses during storage transportation handling or placement it is recommended that steel reinforcement be provided in both the top and bottom to prevent cracking. Use the Naylor Concrete Lintel Selector to work out which lintel you need for your projectrequirements or call us on 0800 542 4192. The self-weight of the lintel has been deducted from the load capacity.

Concrete padstones are a vital part of construction as they designed not to be crushed like regular blockwork when subjected to the pressure of the steel or concrete lintel and the weight above. Concrete Masonry Lintels 6-3 67 Allowable Shear and Moment for Nominal 10 x 8 in. 10Where there is less than 12 of concrete wall length between openings the lintel shall be reinforced to span over both openings.

Concrete Strength 4 8 Ultralintels have a concrete strength of 70 MPa Load Capacity 4 8 Ultralintels have greater load capacity than reinforced lintels due to prestressing Span 4 8 Ultralintels have greater spanning capacity than reinforced lintels 36m for 80 deep Propping 4 8 Ultralintels span further without a temporary prop. HI-STRENGTH RANGE OF LINTELS LOADSPAN TABLE Uniformly distributed service loads kNm The self weight of the lintel must be subtracted from the load given.

Concrete strength is tested on a regular basis in accordance with SANS 5863. A modular lintel length should bespecified which equals the clear span plus at least two times the lintel height to provide for proper bearing at each end. The width of the lintel or the width of the combination of side by side lintels.

Depending upon 1st class to 3rd class work the angle varies from 45 to 60. 5 rows If you have a clear span of 1200mm you will need a 1500mm length lintel to accommodate the. We use cold drawn crimped wire that complies with BS 5896.
