Description

Technical Field

[0002] Tensioning pedestals are tools used to reinforce and strengthen concrete structures, and are often used in the construction of large buildings, bridges, dams, and underground structures. They consist of prestressed steel strands that can increase the tensile strength of concrete structures through tensioning forces, allowing them to withstand greater loads. Tensioning pedestals can effectively enhance the strength of concrete structures and overcome the limitations of concrete, expanding their scope of use. At the same time, they can also reduce the weight of concrete structures, increase their rigidity, and increase their durability. In existing tensioning pedestals, box beams and cross beams are usually connected and fixed with bolts, but there is a risk of bolt breakage, resulting in poor connection strength.
