Problems solved by technology
[0005] However, in the domestic market, there are few manufacturers capable of producing monofilament-coated epoxy-coated prestressed steel strands, and the equipment is scarce. The central wire tensioning equipment used in the steel strand monofilament spraying process has a complex structure and a large volume, accounting for The land area is large, the cost is high, the maintenance and repair costs are high, and the production cost of epoxy steel strands also increases

Description
technical field [0001] The invention relates to a central wire tensioning device used in the steel strand monofilament spraying process. Background technique [0002] With the continuous development of prestressed engineering technology and the continuous expansion of application fields, steel strands are an important part of prestressed concrete structures and bridge structures, and their anti-corrosion performance plays a decisive role in the service life of structures. Therefore, The anti-corrosion requirements of the structure for steel strands are getting higher and higher, and the general anti-corrosion technology can no longer meet the current needs. In order to prevent the aging and corrosion of steel strands, enhance the safety and stability of buildings, and meet the high requirements and standards of prestressed engineering, epoxy-coated steel strands entered the construction market in the 1980s. Nowadays, epoxy-coated steel strands are widely used in long-term a...
