Example:For ASTM A615 Grade 60 bar:1.25 x 60,000psi = 75,000psi Therefore, a splice test exceeding 75,000 psi meets the Type 1 requirement for A615 Grade 60 bar. Type 2 Mechanical Splice shall conform to Type 1 requirements and develop 100% of the specified ultimate strength of the bar being spliced. China Taper Thread Rebar Mecxhanical Coupler - China 1.Taper Thread Machine with Orange Coupler for Rebars From 16mm to 40m This system contains one ZLB-09 taper thread machine and couplers, it can be used to connect rebar of HRB335/400, 16mm- 40mm. The mechanical property of the joint can meet requirements of standard:ACI318-89, ACI359-86, ACI349-89, BS8110-97, DIN1045.
Jul 07, 2015 · Minimum reinforcement of each of two directions at right angles shall have an area of 0.3% for 100 mm thick concrete to 0.2% for 450 mm thick concrete wall. In floor slabs, minimum reinforcement to be provided is 0.15%. The minimum reinforcement as specified above may be decreased by 20%), if high strength deformed bars are used. Evaluation of the Mechanical Properties of Reinforcing Currently, most of the reinforcing steel bars used in the construction industries in Nigeria are produced majorly from scraps. Several researchers [2,   have investigated causes Fabrication of Reinforcement - UK CARESThe CARES Guide to Reinforcing Steels Part 4 Fabrication of Reinforcement Fixing on-site Notation for reinforcing steels (from BS 8666:2005 including amendment) Table 1 Note 1 In the Grade description B500A, etc., B indicates reinforcing steel.

The ALC Alligator Couplers are used for splicing any grade or profile of reinforcing bar. These couplers are made for reinforcement steel with diameters in the range of 10mm to 40mm. Connection is made by inserting bars into both ends of the coupler. The breaking bolts are then screwed by hand and tightened by ratchet wrench until bolts shear off.

nVent LENTON Standard Couplers are designed to splice the same diameter bars where at least one bar is free to be rotated and is not restricted in its axial direction. The couplers are machined to have taper threads at both ends, creating a mechanical butt splice of two sections of reinforcing steel. Standard Specification for Deformed and Plain Carbon-Steel 1.3 Plain bars, in sizes up to and including 2 1 / 2 in. [63.5 mm] in diameter in coils or cut lengths, when ordered shall be furnished under this specification in Grade 40 , Grade 60 , Grade 80 , and Grade 100 . For ductility properties (elongation and bending), test provisions of the nearest smaller nominal diameter deformed bar size shall apply. Steel Reinforcement Bar (Rebar) A Tensile Testing GuideSteel Reinforcement Bar (Rebar) A Tensile Testing Guide Introduction Steel reinforcing bar, or rebar, is embedded in concrete to improve the overall strength of the concrete that surrounds it. Material products standards exist to help ensure that rebar produced throughout the world exhibits the same
