Half grout / full grout concrete grouted splice coupler for rebar
High strength bar splice cement grouted coupler concrete grouting
High strength grout coupler sleeve rebar splice coupler for
Concrete grouted rebar coupler is specially designed to join
reinforcing bars in precast construciton. Reinforcing bars to be
spliced are inserted into grout sleeve and filled with grout,
connecting various precast components such as columns, beams and
shear walls. The performance of grout rebar splicing system meets
different requirements of interenational buidling standards, such
as EuroCode 2, BS8110, ACI318 and JGJ1 etc.
CT type and CTH type. CT sleeve couplers consist of a thread end
where the threaded rebars are turn in and the other end of sleeve
to be grouted. CTH is a fully grouted sleeve used when both rebars
to be joined are not
|Model of sleeve||Rebar size splicing (mm)||Sleeve Diameter(D) ×Length(H)(mm)||Rebar Embedment minimum Depth(mm)||Internal diameter of grouting sleeve D1(mm)|
Remark: 1-above are standard sleeve size;
2-sleeve is made of: quality carbon structural steels or Alloy
3-Mechanical properties: Tensile strength≥600Mpa; Yield
strength≥355Mpa; Percentage elongation after fracture≥16%.
1. Save material and energy,shorten construction period,cost
2. Finishing connection of sleeve one side with rebar at the
factory–Eliminating problems of axis shifting sleeve with rebar and
canceling seal part for sealing the
gap of sleeve with rebar.
3. The length of the sleeve is shorter than the conventional couple
that two side fill the grout for splicing the rebar, since one side
of the sleeve spliced the rebar by
4. It will need lower grouting pressure during filling
high-strength cementitious grout, and easier sealing for horizontal
gap that linking sleeve in precast concrete
members on site.
