Description

Technical Field

[0001] This utility model relates to the technical field of steel cage manufacturing, and in particular to a hand-held tool for binding steel cages in construction. Background Technology

[0002] The reinforcing cage mainly consists of longitudinal reinforcing bars (main bars) and stirrups. Its primary function is similar to that of the longitudinal reinforcing bars in a column, mainly resisting tension. While concrete has high compressive strength, its tensile strength is very low. The reinforcing cage acts as a constraint on the concrete of the pile, enabling it to withstand a certain axial tensile force. During the fabrication of the reinforcing cage, the stirrups need to be tied to the longitudinal reinforcing bars (main bars), requiring the use of a reinforcing bar bending tool. However, existing bending tools, due to the strength of the stirrups, are prone to detaching from the tool during bending, affecting the bending process and thus impacting the fabrication of the reinforcing cage, reducing work efficiency. Therefore, a handheld tool for binding building reinforcing cages is proposed to solve these problems. Summary of the Invention

[0003] The purpose of this utility model is to provide a handheld tool for binding steel reinforcement cages in order to solve the above-mentioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A handheld tool for tying steel reinforcement cages in construction includes a steel pipe. Rectangular openings are symmetrically formed on the inner wall of one end of the steel pipe. One of the rectangular openings has a notch 2 on its inner wall. The other rectangular opening has an arc-shaped groove on its inner wall. One of the arc-shaped grooves has a notch 1 on its inner wall.

[0006] Preferably, a hand sleeve is fitted onto the other end of the steel pipe, and the hand sleeve is made of flexible rubber.

[0007] Preferably, the outer wall of the hand sleeve is provided with a plurality of anti-slip strips evenly distributed, and the anti-slip strips are made of flexible rubber material.

[0008] Preferably, the outer wall of the other end of the steel pipe is provided with a plurality of protrusions evenly distributed, and the inner wall of the hand sleeve is provided with grooves to match the protrusions.

[0009] Preferably, the cross-sections of the protrusions and grooves are both triangular.

[0010] Preferably, a protective shell is fitted onto one end of the steel pipe, and the protective shell is made of flexible rubber.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0012] This utility model utilizes the combined use of rectangular openings, arc-shaped grooves, and notch one and notch two to facilitate quick bending of stirrups. The operation is simple and convenient, improving the efficiency of steel cage fabrication. Furthermore, the use of a hand grip enhances the flexibility of the steel pipe, reducing friction between the pipe and the worker's hands, thus preventing peeling of the skin caused by friction and protecting the worker's hands, thereby improving the comfort of using the hand tool.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution:

[0022] A handheld tool for tying steel reinforcement cages includes a hollow steel pipe 1 to reduce the weight of the tool and facilitate bending of the steel reinforcement. Rectangular openings 6 are symmetrically formed on the inner wall of one end of the steel pipe 1 to allow the steel reinforcement to pass through and bend easily. A notch 2 5 is formed on the inner wall of one of the rectangular openings 6 to allow the steel reinforcement to be secured within the notch 2 5, preventing it from detaching from the steel pipe 1 during bending and thus improving the efficiency of steel reinforcement cage fabrication. An arc-shaped groove 7 is formed on the inner wall of the other rectangular opening 6, and a notch 4 is formed on the inner wall of one of the arc-shaped grooves 7 to further secure the steel reinforcement and prevent it from detaching from the steel pipe 1 during bending, thus facilitating steel reinforcement cage fabrication.

[0023] In this utility model, a hand sleeve 3 is fitted onto the other end of the steel pipe 1. The hand sleeve 3 is made of flexible rubber. The use of the hand sleeve 3 improves the flexibility of the steel pipe 1 and reduces the friction between the steel pipe 1 and the worker's hand, thereby preventing the worker's hands from peeling due to friction. This protects the worker's hands and improves the comfort of using the hand tool. Multiple anti-slip strips 9 are evenly distributed on the outer wall of the hand sleeve 3. The anti-slip strips 9 are made of flexible rubber, which improves the friction between the hand sleeve 3 and the worker's hand and prevents slippage between the hand and the hand sleeve 3, thus facilitating the fabrication of the building steel cage.

[0024] In this utility model, a plurality of protrusions 10 are evenly provided on the outer wall of the other end of the steel pipe 1, and a groove 8 is provided on the inner wall of the hand sleeve 3 to match the protrusions 10. The use of the protrusions 10 and the groove 8 together increases the contact area between the steel pipe 1 and the hand sleeve 3, thereby facilitating a stable connection between the hand sleeve 3 and the steel pipe 1 and benefiting the use of the hand tool. The cross-sections of both the protrusions 10 and the groove 8 are triangular, which increases the contact area between the steel pipe 1 and the hand sleeve 3, thereby improving the stability of the connection between the hand sleeve 3 and the steel pipe 1.

[0025] In this utility model, a protective shell 2 is fitted onto one end of the steel pipe 1, and the protective shell 2 is made of flexible rubber. The use of the protective shell 2 makes it easy to protect one end of the steel pipe 1, preventing the hand tool from getting caught on other objects during transportation, which further facilitates the transportation of the hand tool. The elasticity of the flexible rubber allows the protective shell 2 to be stably fixed to one end of the steel pipe 1, which is beneficial for the transportation of the hand tool.

[0026] Working principle: When using this utility model, during the fabrication of the building steel cage, first, the stirrups are placed on the longitudinal reinforcing bars (main bars), then the stirrups are placed in the rectangular opening 6 of the steel pipe 1, and one end of the stirrup is aligned with the notch 4 in the arc groove 7. At the same time, the arc groove 7 at one end of the steel pipe 1 is locked onto the longitudinal reinforcing bars (main bars), and the opening direction of the arc groove 7 is upward. Then, lifting the steel pipe 1 upward will cause one end of the stirrup to bend, thereby forming a rectangular shape for the stirrup.

[0027] Next, place the reinforcing bar at the opening of the stirrup into the rectangular opening 6, and make the arc groove 7 fit onto the longitudinal reinforcing bar (main bar), with the arc groove 7 opening downwards. Then, place the reinforcing bar at one end of the stirrup into the notch 4 in the arc groove 7, and then press the steel pipe 1 downwards, thereby bending the reinforcing bar at one end of the stirrup downwards. Then, place the reinforcing bar at the other end of the stirrup into the notch 5, and then lift the reinforcing bar upwards, thereby bending the reinforcing bar at the other end of the stirrup upwards, thus forming a rectangular shape for the stirrup to be fitted onto the longitudinal reinforcing bar (main bar). By sequentially fitting each stirrup onto the longitudinal reinforcing bar (main bar), the construction steel cage is fabricated. The operation is simple and convenient, improving the work efficiency of the construction steel cage.

[0028] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
