WANG MENG / ZHANG YUANMING / SHI GANG

The invention relates to a cover plate assembly reinforcing device of a portal rigid frame beam column end plate connecting joint. The cover plate assembly reinforcing device comprises a steel column, a steel beam and a cover plate assembly used for reinforcing. The steel column comprises a column body, column flange outward-extending end plates and column outward-extending end plate stiffening ribs. The steel beam comprises a beam body, a beam overhanging end plate and a beam overhanging end plate stiffening rib, and the beam overhanging end plate is connected with the column flange overhanging end plate; the cover plate assembly for reinforcement comprises a cover plate, flange channel steel and web channel steel, the flange channel steel is connected with the steel beam and the flange of the steel column, and the web channel steel is connected with the web of the steel column. According to the cover plate assembly reinforcing device, the overall mechanical property of the portal rigid frame beam column connecting joint is improved, existing structural members can be flexibly avoided, and the cover plate assembly reinforcing device has the advantages of being easy to install, high in adaptability, low in maintenance cost and the like.
