The Prestressed Concrete Composite Slab with Steel Tube Truss (PK Type Slab) is composed of a C40/C50 concrete base slab, 1570-grade/1860-grade prestressed steel wires, and a concrete-filled steel tube truss.The base slab has a thickness of 35mm or 40mm, a width ranging from 1m to 3m, and a length from 2.1m to 12m.

The top chord of the steel tube truss in this product is a steel tube filled with slightly expansive high-strength mortar.

The top chord of the steel tube truss in this product is a steel tube filled with slightly expansive high-strength mortar.The height can be adjusted according to the thickness of the composite slab.It forms the composite slab together with the cast-in-place layer.

 

Product Advantages:

1,High load-bearing capacity and excellent stiffness;

2,Standardized design has been achieved, allowing for the use of standard design atlases, eliminating the need for detailed design, thereby saving design costs and reducing design time;

3,The use of prestressed steel reinforcement results in lower steel consumption compared to traditional composite slabs;

4,Automated production with CNC concrete distribution ensures high production efficiency;

5,Lower labor requirements and reduced labor costs;

6,Standardized components enable batch production, and the production line comes with its own mold system, allowing for automatic production upon order receipt.
