YGM high-strength finish rolling thread crude steel anchors
Thread tension and anchor system originated in Germany in the domestic DYWIDAG system, called "prestressed high-strength thread bars --YGM system", is by the Ministry of Communications Institute of highway design and planning and I jointly developed. This system has the advantages of low cost, simple process, small volume, light weight, suitable for high altitude operations; the tensile stress is uniform, non slip, wire breaking phenomenon, at the same time relaxation loss value, deformation of anchorage loss, friction loss values are small, easy quality control etc.. Mainly used in vertical prestressed box girder construction, large building roof and rock anchor.
In order to adapt to different load, span, size requirements, currently has two dimensions (phi 25, Phi 32) and two strength (tensile strength and yield strength ratio of 75/100 and 95/120.YGM) reinforced anchorage system by YGM anchor, YGL connector, YGD plate and high strength fine thread rolling rebar composition,.
