ERICO LENTON INTERLOK Rebar Splicing System - Manual (Page 6)

Overview
The LENTON ® INTERLOK Mechanical Reinforcing Steel Splice is designed to connect #5 (16 mm) through #18 (57 mm) rebar,
conforming to ASTM ® A615/A615M, A706/A706M, BS4449, CSA G30.18 or AS1302 standards. The connection incorporates
the LENTON ® taper threaded system in conjunction with a special high-early strength cementitious volume stable filler mate-
rial (grout). Assembly of the connection is normally done in two separate stages: The LENTON threaded end is fastened to
the coupler at a precaster’s plant prior to placement of concrete in the precast member. The connection is completed at the
job site, where the exposed dowel of the adjoining panel is positioned within the interior of the coupler. The filler material is
either poured or pumped into the cylindrical end of the coupler. The coupler can be oriented in either a vertical, inclined or
horizontal position.
The filler material is a special ready-to-use grout, designed to maintain fluidity for an extended period of time while achieving
a high-early-strength. It is a metallic, volume-stable, material capable of developing in excess of 8,500 psi (58.6 MPa)
compressive strength at 28 days. To ensure a proper connection, the addition of water must be maintained in strict
accordance with ERICO recommended procedures. In addition, the temperature of the grout during placing and curing must
be maintained within the recommended guidelines. Misapplication or use of grouts other than ERICO brand of HY10L with-
out ERICO approval voids all warranties, both expressed or implied.
The coupler is produced as a casting and LENTON taper threads are machined under strict Quality Control guidelines. Taper
threading of the rebar ends are produced using ERICO’s equipment. Prethreaded bars can be provided from ERICO’s network
of threading centers, or by positioning a threader at the precasters plant. The threads are right hand and tapered to match
the accompanying coupler.
When assembled in accordance with ERICO recommended procedures, the splice will meet or exceed the ACI 318, BS8110,
AS3600, UBC ® or IBC ® Building Code requirements.
