Description

Technical Field

[0002] Modern architecture is developing towards high-rise buildings, large spans, and complex structures, which places extremely stringent requirements on the load-bearing capacity and seismic performance of reinforced concrete structures. As a key component of reinforced concrete structures, rebar connection technology must keep pace with the times to meet these high standards. Traditional rebar connection methods have gradually revealed various shortcomings when faced with such complex engineering needs. Therefore, there is an urgent need for an innovative rebar connection technology to meet these challenges.

[0003] Traditional rebar connection methods include lap splicing, which has low connection efficiency and may not meet the required strength in some high-stress areas, easily leading to slippage and affecting the overall structural performance. Welding is one of the commonly used rebar connection methods in construction engineering. It can effectively form a stable and reliable connection interface between rebars, thereby significantly improving the connection strength of the entire structure. This high-strength connection not only ensures the overall stability and safety of the building, but also lays a solid foundation for the long-term guarantee of project quality. However, welding quality is affected by a variety of factors, including the technical level of construction personnel, the performance of welding equipment, and environmental conditions. In actual construction, it is difficult to guarantee that every weld point will meet the ideal quality standard. In addition, the high temperature generated during welding may cause changes in the local properties of the rebar, reducing the toughness of the heat-affected zone and increasing the risk of brittle failure of the structure under complex stress conditions, thus failing to meet the user's needs.

[0038] Specifically, the locking assembly 202 consists of several parts, with the core part being a ratchet 2021. The bottom of the ratchet 2021 is securely fixed to the top of the steel reinforcement fixing column 2 4 to ensure its stability and reliability. On the top of the ratchet 2021, there is a slot 2022 for opening and closing, so as to flexibly cooperate with other components. In addition, the locking assembly 203 mainly consists of a pawl 2031. The middle position of the pawl 2031 is cleverly set on the outer wall of the ratchet 2021 to ensure that the two can fit tightly. In order to realize the rotation function of the pawl 2031, a rotating shaft 2032 is rotatably connected to its left side, so that the pawl 2031 can rotate flexibly when needed. Furthermore, the spring-loaded assembly 205 includes several key components, among which the first support column 2051 is an important component.

A clamp 3042 is fixedly connected to the bottom of the second support column 3041. A first steel bar 5 is provided at the bottom of the second steel bar fixing column 4, and a second steel bar 6 is provided at the top of the first steel bar fixing column 207.

[0040] Specifically, the sliding component 302 includes a sliding rod 3021. The outer wall of the sliding rod 3021 is tightly connected to the middle position of the threaded column 301 by a fixed connection to ensure its stability during sliding. The right side of the sliding rod 3021 is fixedly connected to an easy-to-operate toggle button 3022. The user can control the movement of the sliding component 302 by toggling the toggle button 3022. The clamping component 304 is mainly composed of a second support column 3041. The top of the second support column 3041 is firmly installed on the bottom of the turntable 303 by a fixed connection to ensure that the clamping component 304 will not loosen during rotation. The bottom of the second support column 3041 is fixedly connected to a clamp 3042 for clamping objects to securely clamp the target object. In addition, a steel bar 5 is specially provided at the bottom of the steel bar fixing column 207 to provide additional support and fixation. Similarly, a steel bar 6 is also provided at the top of the steel bar fixing column 207 to further enhance the stability and load-bearing capacity of the entire structure.

[0041] Working principle: The ratchet 2021 and the steel fixing post 207 are fixed to the outer casing 1 by means of threaded connection. When the ratchet 2021 is engaged in the slot 2022 and tightened, it can only be tightened counterclockwise. The locking component 203 on the outer wall locks the ratchet 2021 with each rotation, so that the structure is locked. The internal support post 2051 provides full support, and the spring 2052 retracts, making it difficult to fall off easily, thus meeting the user's needs.

[0042] Insert the first reinforcing bar 5 into the bottom reinforcing bar fixing post 4, and insert the second reinforcing bar 6 into the top reinforcing bar fixing post 207. By operating the toggle button 3022, the middle threaded post 301 is rotated, which causes the bottom turntable 303 to rotate, causing the surrounding clamping components 304 to move closer to the center, so that the clamp 3042 clamps the bottom reinforcing bar 5. The top can only rotate half a turn, which is more conducive to user control.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
