Features: Good anchoring performance, improved from linear steel bar bending anchoring to anchor plate surface anchoring; Simple process, high efficiency, nut and pad two-in-one, speeding up construction; Saving steel consumption, after experiment, anchor plate can save 40%-50% of anchor steel consumption compared with traditional bending bar anchoring, reducing engineering costs; Improve engineering quality, solve the problem of anchor congestion, and improve casting quality. The anchor plate of steel bar is a basic skill in concrete structure engineering. The mechanical anchoring skill of steel bar provides a new mechanical anchoring method for the anchoring of steel bar in concrete structure. The anchor plate that combines pad and nut into one is connected to the top of steel bar through straight thread connection method to form a mechanical anchoring material. Its working principle is: the anchoring force of steel bar = the bonding force between steel bar and concrete + the local bearing pressur.Uses of anchor plates: Steel bar anchor plates are suitable for mechanical anchoring of hot-rolled ribbed steel bars in concrete structures. The primary application scope is: using steel bar anchor plates to replace traditional bent bars can be used in beam-column nodes of frame structures: replacing traditional bent bars and stirrups for supporting beams and supports: used for anchoring steel bars in concrete structures such as bridges, hydraulic structures, subways, tunnels, and nuclear power plants; used as fasteners for steel bar anchor rods (or tie rods), etc. Steel bar anchor plates have been widely used in nuclear power plant projects, water conservancy and hydropower, and house construction.
