RLK and RLKP slab supports are steel parts intended for support of precast massive concrete slabs. RLK and RLKP slab support transfers the slab support reaction to supporting walls or other structures.
RLK slab support consists of two square structural hollow section steel tubes that are installed one inside another and ribbed steel bond bars, which are welded to the outer tube.
RLKP slab support consists of two square structural hollow section steel tubes that are installed one inside another and studded steel bars, which are welded to the outer tube. Structural hollow section steel tube with the larger section dimensions is installed to the concrete slab before concrete is cast. The end of the steel tube closer to slab edge is pressed against the mold and the other ends is closed with a welded steel plate, which prevents concrete from entering the steel tube during casting.
During the installation of the precast slab the smaller tube is inserted in to the larger tube. Smaller tube is left protruding from the slab for approximately 95mm and acts as a cantilever support.
