Product Description of Unbonded PC strand
The Unbonded PC strand produced by Henan Hengxing PC Steel Product Co., Ltd implements the industry standard JG161-2004. the Unbonded PC strand is processed on the basis of the standard steel strand after anti-corrosion and grease treatment, making its performance better. More able to satisfy other aspects. Its mechanical properties and other indicators refer to GB/T5224-2003)
The difference between unbonded steel strand and bonded steel strand
There is a layer of rubber sheath on the outside of the unbonded steel strand, while there is no bonded steel strand. Unbonded steel strand is mainly used for post-tensioning prestressing system. The difference between unbonded steel strand and bonded steel strand is that the prestress does not bond with the surrounding concrete. During its working period, the prestress is always allowed to slide longitudinally relative to the surrounding concrete. The prestress is transmitted to the concrete entirely by the anchorage. Unbonded steel strands are mainly used for civil construction projects with large static loads, large-span factories or high-rise buildings. Advantages The construction speed is fast, the thickness of the beam plate is reduced, and the structural performance and economic effect are increased. Bridge construction and large-span garage prestressed construction due to large dynamic load, the design is required to have bonded steel strand, that is, ordinary steel strand. As the construction grouting is directly bonded with concrete, resulting in strong holding force. It is not as difficult to anchor both ends as unbonded steel strand construction, thus enhancing the safety factor. The commonly used prestressed steel strands in prestressed steel strands are low relaxation prestressed steel strands without coating, and some are galvanized. They are commonly used in bridges, construction, water conservancy, energy and geotechnical engineering, etc. Unbonded PC strands are used in floor slab and foundation engineering.
