Description

Technical Field

[0001] The utility model relates to a cushion block, in particular to a steel cage protection cushion block which is easy to rotate and belongs to the field of steel cage construction foundation. Background Art

[0002] During the construction of reinforced concrete structures, cement pads need to be set between the concrete surface and the outermost layer of steel bars as a steel bar protection layer to support the steel bars, prevent steel bar corrosion, and improve the bond between the steel bars and concrete. During the construction process, the traditional through-circle cement pads have poor rotation due to their shape and material. During the construction process, the cement pads tend to squeeze into the pit wall, which can easily cause deformation of the steel bar structure, resulting in a large change in the thickness of the protective layer, which can easily cause quality problems.

[0008] Connecting strips are respectively arranged on both sides of the top and both sides of the bottom of the annular enclosure, and a third through hole is arranged at the inner end of the connecting strip. The outer end of the third through hole is hinged to the annular enclosure.

[0009] The outer wall of the circular pad is tightly attached to the inner wall of the annular enclosure plate.

[0010] The connecting strips are located at the upper end surface and the lower end surface of the circular pad.

[0011] The positive beneficial effects of the utility model are:

[0012] 1. The utility model arranges an annular enclosure on the outside of the circular pad to avoid wear and deformation caused by friction between the circular pad and the inner wall of the foundation pit; and a center tube is rotatably connected inside the shaft sleeve to make the circular pad easier to rotate when subjected to external force, which is convenient for construction workers and can more accurately control the position of the steel bars.

[0013] 2.
