Precast Concrete Onsite

ESPT Offers a complete range of precast concrete moulds onsite, for the pre-tension concrete girders onsite. ESPT supply, design and manufacturer Self stressed moulds for precast concrete Girders.

Types of Long line beds: 1-Abutment Type 2-Self-Stressed mould

Abutment type is usually used in permeant beds, where no need to mobilize the bed. Self stressed moulds can be mobilized to different sites and can accommodate different sections to be pre-cast onsite.

Self-Stressed Moulds for Bridge Girders

Self-stressed moulds for bridge girders are innovative systems designed to produce prestressed concrete girders efficiently and with high precision. These moulds are engineered to withstand the tensioning forces internally, eliminating the need for external abutments or anchoring systems.

How Self-Stressed Moulds Work 1.Integrated Prestressing System: The mould itself is designed to handle the forces generated during the prestressing process. This is achieved through built-in reacting columns or frames. 2.Tensioning and Casting: High-strength steel tendons are tensioned within the mould before the concrete is poured. The mould absorbs the tensioning forces, ensuring stability. 3.Curing and De-tensioning: After the concrete cures, the tension is gradually released, transferring the prestress to the girder.

Advantages Portability: Self-stressed moulds can be relocated easily, making them ideal for on-site production in remote areas. Efficiency: They streamline the production process by integrating tensioning and casting in a single system. Cost-Effectiveness: Reduces the need for heavy infrastructure, such as external abutments, lowering overall costs. Precision: Ensures consistent quality and alignment of girders.

Applications These moulds are commonly used for: Bridge Construction: Producing girders for highway and railway bridges. Infrastructure Projects: Ideal for viaducts and overpasses. Custom Designs: Suitable for various girder profiles, including I-girders, U-girders, and box girders.
