Description

Technical Field

[0001] This utility model relates to the field of building technology, and more specifically, to a steel reinforcement detection device for building construction sites. Background Technology

[0002] In the field of construction engineering, steel reinforcement, as the core skeleton material of concrete structures, directly affects the safety of the project. Existing steel reinforcement testing devices mostly employ electromagnetic induction, ultrasonic, or optical measurement technologies to detect parameters such as steel reinforcement corrosion, cracks, diameter, and spacing. Some devices integrate automated transmission systems to achieve batch testing. These devices play a crucial role in construction quality monitoring, using data analysis to assist in determining material properties and effectively preventing structural hazards caused by substandard steel reinforcement.

[0003] Rebar bending is a core process in component forming. Because manual operation relies on experience and judgment, it is prone to axial displacement or local buckling of the rebar during bending due to factors such as loading speed, fulcrum positioning deviation, or material inhomogeneity. This displacement not only causes the component dimensions to exceed specifications but can also lead to equipment jamming, mold damage, or even rebar breakage and ejection, forming high-speed flying debris that poses a significant safety threat to construction workers and surrounding equipment.

[0004] Therefore, we have made improvements to this and proposed a steel reinforcement detection device for construction sites. Utility Model Content

[0005] The purpose of this utility model is to address the current problem that, due to manual operation relying on experience and judgment, steel bars are prone to axial displacement or local buckling during bending caused by loading speed, fulcrum positioning deviation, or uneven material.

[0006] In order to achieve the above-mentioned objectives, this utility model provides a steel reinforcement detection device for construction sites to improve the aforementioned problems.

[0007] The application is as follows:

[0008] It includes a base and a bending groove formed on the long side of the base, and an electric push rod is fixedly connected to one side of the base located on the bending groove.

[0009] The bending groove is provided with a fixed plate and an L-shaped plate on both sides. The adjacent ends of the fixed plate and the L-shaped plate are rotatably connected with pressure plates. A buffer pad that restricts the pressure plate from sticking to the L-shaped plate is fixedly connected to the L-shaped plate. The electric push rod is elastically set with the L-shaped plate through a bridging rod.

[0010] As the L-shaped plate moves toward the fixed plate, the pressure plate is tilted at the tangent position of the steel bar section due to the pressure of the buffer pad and the steel bar.

[0011] Preferably, the bent end of the L-shaped plate is elastically disposed on the base, and the elastic direction of the L-shaped plate is perpendicular to the bending groove.

[0012] Preferably, the bending groove includes a straight groove and a fan-shaped groove for bending the reinforcing bar, the output end of the electric push rod is located on one side of the fan-shaped groove of the bending groove, and the L-shaped plate is located on one side of the straight groove of the bending groove.

[0013] Preferably, when the pressure plate rotates toward the bending groove, the pressure plate contacts the inner wall of the bending groove.

[0014] Preferably, the maximum extension distance of the electric push rod is consistent with the maximum deformation length of the bridging rod and the L-shaped plate compression spring.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] To address the problem in existing technologies where manual operation relies on experience and is prone to axial displacement or local buckling of reinforcing bars during bending due to factors such as loading speed, fulcrum positioning deviation, or material inconsistency, this application addresses this issue by using a pressure plate at the end of an L-shaped plate. This plate is tilted to one side of the reinforcing bar as it moves with the electric push rod, providing downward and lateral pressure to the reinforcing bar and preventing it from coming out of the bending groove, thus achieving multi-directional fixation of the reinforcing bar.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0026] As described in the background art, manual operation relies on experience and judgment, which can easily lead to axial displacement or local buckling of the reinforcing bars during bending due to loading speed, fulcrum positioning deviation, or uneven material.

[0027] To solve this technical problem, this utility model provides a steel bar detection device for construction sites. It is used to gradually increase the fixing force according to the bending force during the bending process, so that the steel bar is not subjected to large pressure in a short period of time, which may cause the steel bar to deviate and cause danger during the bending process.

[0028] For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A steel reinforcement detection device for construction sites specifically includes:

[0029] The base 1 and the bending groove 2 opened on the long side of the base 1 are provided. An electric push rod 5 is fixedly connected to one side of the bending groove 2 on the base 1. The electric push rod 5 serves as the main power source for bending the steel bar, so that the steel bar can also move the L-shaped plate 4 by pulling the bridging rod 6 during the bending process.

[0030] Fixed plates 3 and L-shaped plates 4 are provided on both sides of the bending groove 2. Pressure plates 41 are rotatably connected to the adjacent ends of the fixed plates 3 and L-shaped plates 4. Buffer pads 42 that restrict the contact between the pressure plates 41 and L-shaped plates 4 are fixedly connected to the L-shaped plates 4. The electric push rod 5 is elastically set with the L-shaped plates 4 through a bridging rod 6. Since the pressure plates 41 can rotate freely on the fixed plates 3 and L-shaped plates 4, when they are squeezed into the straight groove of the bending groove 2 by the reinforcing bars, they are symmetrically distributed in the gap between the bending groove 2 and the reinforcing bars, which plays a basic limiting role.

[0031] When the L-shaped plate 4 moves toward the fixed plate 3, the pressure plate 41 is tilted at the tangent position of the steel bar section under the pressure of the buffer pad 42 and the steel bar. When the bending action begins, the end of the electric push rod 5 squeezes the steel bar and causes it to bend. At the same time, the bridging rod 6 fixed at the extension end of the electric push rod 5 drives the L-shaped plate 4 to move toward the fixed plate 3. The greater the bending action, the stronger this tendency becomes. When the bending action is too large and the steel bar tends to deviate, the L-shaped plate 4 is displaced, causing the pressure plate 41 to move around the circumference of the steel bar and gradually tilt and contact the steel bar line. At this time, the pressure plate 41 provides a force to inhibit the steel bar from moving upward and to the sides. With the cooperation of the buffer pad 42, the pressure plate 41 controls the tilting tendency and prevents excessive tilting from causing it to stick to the L-shaped plate 4.

[0032] For an example, please refer to... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A steel bar detection device for construction site of building engineering, wherein the bent end of the L-shaped plate 4 is elastically set on the base 1, the elastic direction of the L-shaped plate 4 is perpendicular to the bending groove 2, and the L-shaped plate 4 can move in the direction of the bending groove 2 and restrict the movement of the steel bar.

[0033] The bending groove 2 includes a straight groove and a fan-shaped groove for bending the reinforcing bar. The output end of the electric push rod 5 is located on one side of the fan-shaped groove of the bending groove 2, and the L-shaped plate 4 is located on one side of the straight groove of the bending groove 2. The electric push rod 5 causes the reinforcing bar to complete the bending action in the fan-shaped groove, and the fan-shaped groove provides the space required for the bending action.

[0034] When the pressure plate 41 rotates toward the bending groove 2, the pressure plate 41 contacts the inner wall of the bending groove 2, and after contact, it provides lateral extrusion force and acts as a resistance force to prevent the steel bar from shifting.

[0035] The maximum extension distance of the electric push rod 5 is consistent with the maximum deformation length of the compression spring of the bridging rod 6 and the L-shaped plate 4, to prevent the electric push rod 5 from moving too far and causing the L-shaped plate 4 to come into contact with the fixed plate 3, resulting in damage to the components.

[0036] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
