Since the 21st century, the steel bar protection layer of concrete projects has gradually become a key quality management indicator in various industries. While improving the quality of the protection layer, new problems have also been highlighted. Taking highway projects as an example, in order to improve the qualified rate of the steel bar protection layer of concrete projects and ensure that the project acceptance quality inspection is qualified, a large number of template tension bars, top bars, and measure steel bars are added to the concrete of bridges, tunnels and various structures. These steel bars have played a positive role in improving the accurate positioning of the main steel bar skeleton, and at the same time have brought new hazards to the overall structural durability of concrete. Because these steel bars are on the surface of the concrete, they are seriously exposed and are more likely to rust and cause concrete damage.

[0003] At present, in order to protect the ends of steel bars, plastic top bar caps are often used to protect them. However, since the specifications of the plastic top bar caps need to be customized according to the specifications of the steel bars, they cannot be adapted to the various specifications of steel bars in the construction project.

[0008] As a further solution of the utility model, the wedge block assembly includes a first wedge block and a second wedge block, the plane of the first wedge block is fixedly connected to the sealing arc plate, a special-shaped connecting plate is fixed to the inclined side of the first wedge block, the inclined side of the second wedge block is provided with a special-shaped groove for sliding connection to the special-shaped connecting plate, and the plane side of the second wedge block is slidably connected to the limiting ring groove set at the bottom of the mounting ring.

[0009] As a further solution of the utility model, the number of the guide posts is two groups, and the two groups of guide posts are arranged in parallel along the axial direction of the outer cap.

[0010] As a further solution of the utility model, the number of the sealing arc plates is four groups.

[0011] Compared with the prior art, the utility model designs an inner cap and an outer cap, wherein the open end of the inner cap is inserted into the outer cap and is threadedly connected to the inner cap, and a plurality of groups of sealing arc plates are evenly arranged along the circumference of the bottom of the outer cap, and the sealing arc plates are limit-connected to the bottom of the inner cap through a wedge block assembly.

[0021] When the inner cap 1 rotates relative to the outer cap 2, it drives the multiple sets of sealing arc plates 5 to move concentrically;

[0022] Specifically, during the installation process, the construction workers directly put the utility model on the exposed end of the reinforcement. The workers can hold the inner cap 1 and rotate the outer cap 2. The inner cap 1 and the outer cap 2 are relatively displaced, and the wedge block assembly 4 is driven to drive multiple groups of sealing arc plates 5 to move concentrically close to the center of the outer cap 2 to clamp the end of the reinforcement 3. At the same time, the sealing rubber pad 501 is squeezed and deformed. While ensuring the clamping of the sealing arc plates 5, the gaps between adjacent sealing arc plates 5 are filled to reduce the size of the gaps between the sealing arc plates 5.
