Thread Bar / Post-Tensioning Bar 1. Grade:PSB930 2. Length:9m 12m or as per customers requirements 3. Application:High-speed Railway bridge concrete anchoring system formwork panels industrial facilities precast-construction water treatment CRSI:Splicing BarCRSI recommends against connecting crossbars by small arc welds, known as "tack welds." Tack welding is a factor associated with brittle failure of rebar assemblies. Coupler for Thread-Deformed Bar. This is a mechanical splice that requires special bars with thread-like rolled, deformations over their entire length which meets ASTM A615.

Jan 04, 2020 · According to ASTM A1034; a coupler is a threaded device for joining reinforcing bars for the purpose of providing transfer of either axial compression or axial tension or both from one bar Rebar Vs Deformed Bar Anchor - Structural engineering Oct 11, 2013 · RE:Rebar Vs Deformed Bar Anchor. tolchijb (Structural) 11 Oct 13 14:30. A deformed bar anchor is more like a headed stud with deformations on the shaft. Typically they thread the end of a reinforcing bar and screw on a "hockey puck" The development length is much shorter than a typical rebar and because of the deformations on the shaft it is
ReidBar is a user friendly continuous coarse thread reinforcing bar system that is fast, easy to assemble and readily available in New Zealand. Confidence in quality. ReidBar's continuous thread does not require pre threading of the reinforcing bar. This means no testing on the reinforcing bar (as referenced in NZS3101:2006 Reidbar and threaded connecting couplers Fletcher ReidBar 500E, is a micro-alloy, hot-rolled, continuously threaded reinforcing bar which can be cut at any length and joined using ReidBar threaded connectors. ReidBar is manufactured to AS/NZS4671:2001 Steel Reinforcing Materials by Pacific Steel with the deformations forming a continuous right-hand thread allowing it to be cut and joined
MOMENT Weldable coupler is designed for connecting reinforcing bar to structural steel members such as plates, piles, beams, columns, etc. The coupler is normally arc welded to the structural steel in a fabricating yard. Reinforcing Bar Couplers AnconReinforcing Bar Couplers. Lapped joints are not always an appropriate means of connecting rebar. The use of Ancon Reinforcing Bar Couplers can simplify the design and construction of reinforced concrete and reduce the amount of reinforcement required. For assistance on the correct choice of coupler, please consult the Coupler Selection Chart or
Standard stainless steel reinforcing bar (rebar) diameters range from 6mm to 40mm. Stock lengths vary from 6.0 to 6.1m and bars can be supplied cut to any length. Bars are available bent according to the shape codes given in BS 8666. Threaded ends with ISO metric threads to BS 3643 can be supplied for fixing applications.
