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. Example:For ASTM A615 Grade 60 bar:1.00 x High-Strength Reinforcement Systems (HSRS®)High-Strength Reinforcement Systems (HSRS®) The SAS Grade 80 and Grade 97 high-strength reinforcing bars and accessories are innovative products, far surpassing conventional reinforcing materials. Combined with innovative engineering design, our products can be used as a high-performance structural alternative, primarily utilized in the construction of high-rise buildings and deep

Rebar Coupler vs Rebar Lapping Steel Coupler MOMENT

May 08, 2018 · In almost all reinforced-concrete structures, rebars must be spliced. The required length of a bar may be longer than the stock length of steel, or the bar may be too long to be delivered conveniently. In either case, rebar installers end up with two or more pieces of steel that must be spliced Reinforcing Bar Couplers - AmsteeleThey are designed to achieve failure loads in excess of 115% of the characteristic strength of grade 500 rebar.

A pro p ri e t a r y high strength grout pumped in-to the sleeve using a low pre s s u r e grout pump forms an interlock between rebar deformations and the intern a l ribs of the sleeve. Some disadvantages of this system are its bulkiness,

    Splicing Bar - CRSI

    One end of the sleeve is attached and secured to a reinforcing bar (rebar) by means of threading. The splice is then completed when the other bar end is inserted into the sleeve and the space between the bar and the sleeve is filled with high-strength grout. The wide mouth opening of the sleeve allows for minor bar misalignment during erection. Threaded Rebar Coupler Sale Mechanical Rebar Splicing Jul 19, 2021 · Threaded rebar coupler, also known as the names rebar connectors, rebar splicing, mechanical rebar couplers is a joint of steel bars on a parallel line which is designed for reinforcement bars and usually used in conjunction with a rebar threading machine.The thread rebar with an internal thread corresponding to the thread is a mechanical rebar coupler used to transfer the axial tension or US5411347A - High dynamic strength reinforcing bar splice A high dynamic strength or fatigue resistance is achieved in a taper thread reinforcing bar splice for use in steel reinforced concrete by coordinating the elongations of the coupler sleeve and bar

    US6679024B2 - High strength grouted pipe coupler -

    This invention relates to a high strength grouted pipe coupler by which either a pair of spaced, axially aligned steel reinforcing bars (i.e. rebars) are reliably spliced to one another or a single reinforcing bar splicing coupler, reinforcing bar splicing Methods of Splicing Reinforced Bars - The ConstructorSep 09, 2014 · A continuous reinforcement bar is obtained through this coupler splicing. The errors due to wrong lap length as in conventional method is avoided. The wastage of steel is reduced. Use of a mechanical joint helps to avoid lap length. This will save appreciable amount of steel. We can use couplers as dowel bars. This will save the formwork material.Reinforcing bar couplers - CortartecSplicing is not always the best way to join steel reinforcing bars. The use of Ancon couplers simplifies the design and construction of reinforced concrete structures and reduces the amount of reinforcement needed. The range of Ancon CTT conical thread couplers has been designed to be applied with cryogenic quality reinforcing rods.
