[0002] With the increasing number of high-rise buildings, different grades of concrete adjacent surfaces are left in reinforced concrete structures. The beam-column nodes of high-rise building frame structures are relatively complex. Due to the results of load combination and internal force calculation, in order to meet the requirements of column axial compression ratio and control the column cross-sectional size, the concrete strength grade of columns and walls on the same floor is required to be higher than that of beams and slabs. This results in large differences in the concrete grades of beams and columns in the structural reinforcement layer. The conventional practice is to use wire mesh, but the mesh is generally not in place. The wire mesh is generally set at the bottom of the main reinforcement of the beam, and is not set at the top of the beam and the slab surface. At the same time, due to the flow of concrete during pouring, the concrete grades of beam-column joints are often confused. Utility Model Content
