Abstract
The utility model relates to the technical field of building construction, and discloses a column head protection device for a post-filling frame column, which is an enclosure structure formed by sequentially clamping and connecting a plurality of unit pieces in sequence, each unit piece comprises a rectangular plate, a clamping groove located in one side of the rectangular plate and a T-shaped clamping block located on the other side of the rectangular plate. An inverted-T-shaped opening is formed in the clamping groove, and the clamping block can be clamped in the opening and rotate relative to the clamping groove. The column head protection device has the advantages that the rectangular plates, the clamping grooves and the clamping blocks form unit pieces, and then the unit pieces are sequentially connected to form the column head protection device. The protection device is easy to manufacture, can be produced in batches and can effectively prevent backfill from entering gaps of the steel bars. Meanwhile, the structure is convenient to disassemble, and the construction period pressure of a project can be greatly relieved.
