The PJ Projects rib and block concrete slab system are the best choice you can make for your next building project because they make building quicker and more cost-effective. The job is quicker and easier and keeps costs low.
The rib and block concrete slab systems make adding a floor quicker and easier.
The hollow-core blocks make filling up with concrete more efficient on concrete used, making the floor lighter in weight, and setting time for the concrete is decreased dramatically.
The ribs are purpose-made under strictly controlled factory conditions, eliminating potential problems of one-size-fits-all situations. A large variety of cast-in reinforcing combinations allows for economical design.
PJ Projects Lattice – Reinforced
The lattice provides a rigid steel truss-like structure, which, when cast into the concrete enables the rib to withstand handling loads and support the weight of the hollow blocks, and construction loads. It also contributes towards the tensile reinforcement required in the completed slab and provides an excellent shear key between the pre-cast rib and concrete.
1. The rib and block concrete slab eliminates the need for conventional in situ decking systems.
Because the ribs and blocks for the complete deck into which the concrete is poured, the ribs merely require temporary support until the concrete has gained strength. Propping centres will vary from case to case and will be specified by the Engineer.
2. The rib and block concrete slab reduces the amount of concrete required between 30% and 40%.
Because the hollow concrete block replaces a substantial volume of in-situ concrete leading to a significant reduction in the dead load supported by the structure sub-sequential cost savings made by the consequent reduction in size of other elements such as the beams, columns, and foundations.
3. Easy to assemble – almost like a puzzle.
Due to the simplicity of the system, it can be swiftly installed on-site using less skilled labour than is needed for more conventional slab constructions. The use of ordinary pre-cast ribs means that the ribs are always straight, simplifying the installation of the beams and the placing of the blocks inbetween. The lattice girder adds stiffness and handling facilities to the beam. The time for installation of the system will be reduced.
5. No crane is required for installation.
