Domed plate
When choosing a domed plate, firstly, it is necessary to meet the strength matching between the domed plate and the anchor bolt body, so as to avoid the phenomenon of anchor bolt perforation caused by insufficient strength of the domed plate. The second is to meet the matching of the anchor bolt and the anchor bolt body on the supporting structure, so as to avoid uneven force on the anchor bolt body and nut due to the mismatch between the anchor bolt body and the domed plate on the supporting structure, which will affect the support of the roadway protection effect.
