Prestressed hollow jack is a tool specially used for prestressing tensioning operations. Its core feature is that there is a through hole in the center, which can be used with prestressed tendons such as steel strands. The application scenarios are mainly concentrated in engineering fields where prestressing is required on the structure, as follows:
Bridge Engineering
- Widely used for prestressing of beams (such as simply supported beams and continuous beams). By tensioning steel strands, the beams are prestressed to enhance their bearing capacity and crack resistance.
- In the construction of cable-stayed bridges and suspension bridges, it is used to tension cable stays and slings to ensure the stability and force balance of the bridge structure.
Construction Engineering
- Commonly used for tensioning components such as prestressed concrete slabs, roof trusses, crane beams, etc., to improve the stiffness and deformation resistance of components and reduce cracks during use.
- In the construction of large-scale building foundations (such as pile foundations and caissons), it can be used for prestressed reinforcement to improve the bearing capacity of the foundation.
Water conservancy projects
- In the construction of water conservancy facilities such as sluices, aqueducts, and dams, the prestressed tendons are stretched to enhance the impermeability and integrity of the structure to cope with loads such as water pressure.
Transportation projects
- Prestressed construction of structures such as culverts and tunnels for roads and railways to ensure their durability under repeated vehicle loads.
In short, prestressed hollow jacks play a key role in various projects that require prestressed technology to improve structural performance, thanks to their adaptability to prestressed tendon tensioning.
