[0002] The steel bar protection layer refers to the part of concrete in the concrete component that protects the steel bars from being directly exposed. It is the minimum distance from the concrete surface to the outer edge of the nominal diameter of the outermost steel bar (the stress-bearing steel bar). When the steel bar skeleton is placed in the mold in daily life, a guard ring is required to protect the steel bar skeleton.

[0003] For example, application number 202222448017.6 discloses a protective layer guard ring for a concrete pole steel frame, comprising a polymer Mpp polypropylene protective layer gasket and a protective ring. The polymer Mpp polypropylene protective layer gasket is C-shaped, and an inner clamping ring is fixedly installed on the inner side wall of the polymer Mpp polypropylene protective layer gasket, and a clamping block is fixedly installed on the circumferential surface of the polymer Mpp polypropylene protective layer gasket. A handle is fixedly installed between the polymer Mpp polypropylene protective layer gasket and the inner clamping ring. The utility model can prop up the steel frame through multiple clamping blocks on the circumferential surface of the polymer Mpp polypropylene protective layer gasket to prevent the steel frame from deviating from the center position of the mold. At the same time, the polymer Mpp polypropylene protective layer gasket is corrosion-resistant, high in strength, not easy to loosen and fall, can effectively achieve the function of a protective layer, can use the coaxial reinforcement of the skeleton main reinforcement to divide it into four equal parts, and correctly clamp it on the main reinforcement.

[0004] However, although this type of concrete pole steel frame protective layer guard ring can better protect the steel frame when in use, the guard ring is often directly clamped on the steel frame, and the limiting effect of the guard ring is not high.

[0026] Furthermore, the outer wall contour of the locking ring 13 is larger than the outer wall contour of the steel bar body 11, and two groups of locking rings 13 are provided. The position distribution of the two groups of locking rings 13 is symmetrical about the central axis of the steel bar body 11. The guard ring body 12 has toughness, which is conducive to the setting of the outer wall contour of the locking ring 13 being larger than the outer wall contour of the steel bar body 11, so as to realize the control operation of convenient locking of the steel bar body 11 by the locking ring 13.

[0027] Furthermore, a telescopic groove 215 is provided at the connection position between the outer wall of the connecting box 211 and the telescopic block 213. The telescopic block 213 forms a telescopic structure with the connecting box 211 through the connecting block 212 and the telescopic groove 215, which is conducive to pressing the connection of the connecting block 212 through the telescopic groove 215, driving the telescopic block 213 to perform reciprocating telescopic movement along the outer wall of the connecting box 211, thereby realizing the control operation of the squeezing movement of the spring 214.
