cations for tension lap splices result in long lap splice lengths, especially for bar sizes such as #9, #l0, and #ll in Grade 60 steel or in epoxy-coated reinforcing bars. Lap splices may thus be less practical than mechanical connections. 4. Where tension tie members are used. Tension lap splices of reinforcing bars in tie members are not
BPI BARSPLICER EdingAPSIn the field, reinforcing bars are cast in concrete with the flanged coupler attached to the form face. After the formwork is removed, straight or bent splice bars are installed into the coupler to extend the reinforcing bar. A simple pipe wrench can be used to snug and secure the splice assembly. No torque wrench is required for this operation.
Mar 11, 2021 · Couplers on epoxy-coated bars require corrosion protection covering Service and ultimate butt splices are defined in section 52 of the Standard Specifications This table was prepared to provide a reference source for rebar splicing systems currently authorized for use by Caltrans.
Lapping of Reinforcements and Use of Rebar Couplers Jul 01, 2020 · Lapping (reinforcement splicing) is the traditional way that has been used to join two different reinforcements during construction. However, in recent times, mechanical splices (such as rebar couplers) have been introduced to make two different pieces of reinforcements joined together to behave as one continuous unit.
Mechanical Bar Splicers Dowel Bar Splicer SystemA BARSPLICER is composed of setting bar and a splice bar. At your option, setting bars are supplied with or without a flange on the coupler. Couplers on the setting bars are power-locked by BPI to be inte-gral with rebar. Our couplers will not loosen during transportation, placing and service. *Py = specified yield; fy x Cross Sectional Area
Splice systems are compliant with ACl 318 specifications & AASHTO standard specifications for highways & bridges. All threaded couplers are made from material satisfying ASTM A-108. EDC threaded mechanical splicing systems are supplied as 2-piece systems, which include a male splice bar and a female setting bar with a coupler attached.

REINFORCING BAR SPLICER ASSEMBLIES AND When installing Bar Splicer or Mechanical couplers it is critical that the male reinforcement bar(s) have the correct thread for proper installation into the coupler assembly. For example, a straight threaded barrel coupler cannot use a male tapered threaded reinforcement bar (see picture below). Domestic Steel Act
Dowel Bar Mechanical Splices. Dowel bar mechanical splices are flanged couplers that can resist tension and compression forces. This splice is nailed to the end or sides of the formworks through holes created in the flange. The connection between reinforcement bars and the splice is through internal threads of the splice.
What is Reinforcement Coupler Benefits of Mechanical Rebar coupler creates couplers joint between reinforcing bars to connect together, whose bar ends are in contact and parallel. Benefits of Mechanical Splices or Rebar coupler:1.Improved structural integrity Mechanical splices maintain load path continuity of the reinforcement, independent of the condition or existence of the concrete.NMB Splice SleeveThe NMB SPLICE-SLEEVE ® is a mechanical coupler for splicing reinforcing bars which uses a cylindrical shaped steel sleeve filled with a Portland cement based non-shrink high early strength grout. Reinforcing bars to be spliced are inserted into the sleeve
