Precast Lattice Girder Slabs Production Line

Lattice Girder Floors

Combining precast and cast-in-place concrete, lattice girder floors offer numerous advantages:

Advantages of Lattice Girder Slabs

• Efficient Construction: The elimination of formwork during the construction phase results in shorter construction times, increased efficiency, and reduced labour costs.

• Improved Quality: Prefabricated components are produced in a controlled factory environment, ensuring consistent quality.

• Superior Structural Performance: Lattice girder slabs have high overall stiffness, excellent seismic performance, and are highly cost-effective.

• Smooth Finish: The smooth underside of lattice girder slabs eliminates the need for plastering, saving time and cost.

Lattice Girder Slab Production Process Flow

1. Pallet Cleaning

2. Shutter Placement

3. Spraying of Release Agent and Retarder

4. Reinforcement Placement

5. Embedded Part Placement

6. Concrete Pouring

7. Vibration

8. Pre-Curing

9. Roughening

10. Curing

11. Demoulding

Detailed Steps:

1. Pallet Cleaning: Clean the pallet to remove any residual material from the previous production.

2. Shutter Placement: Place the shutters according to the dimensions of the prefabricated component.

3. Release Agent Application: Apply a release agent to the pallet surface to facilitate demoulding.

4. Reinforcement Placement: Place the cut reinforcement in the designated positions.

5. Embedded Part Placement: Place embedded parts. Reinforcement is connected using wire ties to ensure it remains in place during the pouring process.

6. Concrete Pouring: Pour the concrete onto the pallet.

7. Vibrating: Consolidate the concrete using a vibrator.

8. Pre-Curing: Allow the concrete component to cure for a short period.

9. Roughening: Create a rough surface on the slab to improve adhesion for the subsequent concrete pouring on-site.

10. Curing: Cure the concrete component in a curing chamber for an extended period.

11. Demoulding: Remove the finished component from the pallet.
