BMS PRECAST CONCRETE COUPLER

Transfers stress generated at the head and rebar ribs to the sleeve through mortar injected between the splice sleeve and the headed rebar.

◆  Advantages of Grout Sleeve

· Accommodates construction tolerances easily due to the generous clearance between the rebar and sleeve

· Ideal for connecting precast members as there is no rebar expansion/contraction

◆ Grout Sleeve Installation Examples

Even when axes do not align (eccentricity up to 10 mm), engagement length is easily adjusted. After tightening, the bearing nut sits flush to resist compressive forces, while the coupler itself rotates during splicing to deliver full tensile resistance without bending the rebar.

◆  Advantages of BMS Universal Coupler

The Universal Coupler connects precast (PC) members by threading a bearing nut onto the protruding rebar and tightening the assembly. Even with an eccentricity of up to 10 mm or an angular inclination of up to 16°, the coupler itself rotates to achieve full engagement, offering excellent constructability.
