PAUL mobile hydraulic stations are used to operate such hydraulic equipment as: tensioning jacks, stress relieving cylinders, cutting tools, etc., used in the production of prestressed concrete elements.
Tensioning jacks are used for steel reinforcement, wire and multiple-core steel strands at the concrete products plants and on-site. Jacks are distinct in tension force, power stroke and number of simultaneously tensioned reinforcement bars
PAUL manufactures a wide range of anchor grips for anchoring or jointing of different types of reinforcement, wire or multiple-core steel strands. Structurally, PAUL anchor grips consist of cases and clamping wedges. According to the design of the case, there are three types of grips:
— Open type. “A”-type Anchor grip
— Enclosed type. “F”-type Anchor grip
— “K”-type Coupling
Prestressed reinforced concrete technology is a construction material that is widely used in the world (in recent decades it has been used in Ukraine and other CIS countries). Special reinforcement technology is used to produce such concrete, using the inability of the concrete to withstand high tension stresses. This makes it possible to increase the durability and fatigue life of the finished product
Structures made in this way are much less bent and much less prone to cracks (2 - 3 times higher compared to concrete products without prestressing). Furthermore, they are characterized by uniform strength, which makes it possible to cover large spans. Prestressed reinforced concrete makes it possible to reduce the consumption of reinforcing material by 50%.
A special feature of the manufacturing process of prestressed reinforced concrete products is the preliminary laying of reinforcement for tension. The wire or strands are tightened with a special device and then a concrete mixture is laid on them. After the concrete has set, the reinforcement is released and tension force shifts to the concrete mixture in such a way that it compresses and preserves the state.
The generation of tension force enables the manufacturer of reinforced concrete products to completely or to a certain extent avoid tension stresses under load during operation.
Depending on the equipment at the plant, the reinforcing material can be tightened in different ways:
This prestressed reinforced concrete technology is widely implemented worldwide, as it gives the constructor many advantages:
Prestressed reinforced concrete technology is now widely used for the construction of buildings for various purposes: housing, offices, industrial facilities, storage spaces, marketplaces.
