Reinforced Steel Truss Fine Stone Concrete Composite Slab (HJ Slab) – Project Case PPT

Reinforced Steel Truss Fine Stone Concrete Composite Slab (HJ Slab) – Project Case PPT

The HJ prefabricated, non-removable bottom-formwork steel truss composite slab is manufactured mechanically in a factory. A alkali-resistant fiberglass mesh cloth is laid on the bottom of the mold, and after pouring 20 mm-thick fiber-reinforced fine aggregate concrete, a steel truss with embedded connecting reinforcement is inserted. The fiber-reinforced fine aggregate concrete completely encases the connecting reinforcement, forming the bottom slab. Once cured and hardened, this component becomes a precast element. During construction, it serves as formwork capable of bearing all construction loads; in the service phase, it works together with the cast-in-place concrete to form the HJ steel truss composite floor slab.

The Application and Development of Steel-Reinforced Truss Composite Slabs in Modern Construction

The Application and Development of Steel-Reinforced Truss Composite Slabs in Modern Construction

With the acceleration of building industrialization and the growing popularity of green building concepts, traditional cast-in-place concrete floor slabs have gradually revealed several drawbacks, including long construction periods, high formwork usage, and poor on-site working conditions. As a new type of prefabricated floor slab system, steel-reinforced truss composite slabs perfectly combine the mechanical advantages of steel trusses with the material properties of concrete, demonstrating significant advantages in terms of construction efficiency, cost-effectiveness, and structural performance.
