Description

Technical Field

[0001] This utility model relates to the field of grounding clamp technology, specifically to an assembly structure for a three-dimensional steel bar clamp. Background Technology

[0002] Against the backdrop of repeated wildfires caused by welding of grounding steel bars on power towers, the state issued a document prohibiting the use of welding methods for connecting grounding steel bars on power towers during the fire prevention season. This has led to the development of two new grounding methods for power tower steel bars. One is the sleeve crimping grounding method, which involves inserting two steel bar ends into the same section of low-carbon steel pipe (or welded cross-shaped steel pipe), and using an electric hydraulic station and hydraulic compression mold to crimp the steel pipe to reduce its diameter, thus achieving a grounding connection of two to four steel bars. The other is the bolt grounding method, which involves on-site threading of the two steel bar ends before connecting them to the grounding system. The first method involves tightening the two ends of the pre- and post-threaded nut column, rotating the nut to tighten the reinforcing bar in both directions until the end of the reinforcing bar is completely screwed into the tightening sleeve, thus achieving a secure connection between the two reinforcing bars for grounding. However, this method requires the use of an electric hydraulic station and hydraulic compression hole mold, making the auxiliary machinery and tooling bulky. It is also limited by the need for on-site power supply, and the labor intensity is high, resulting in low efficiency. The second method requires on-site threading when grounding the reinforcing bar, which requires manual tools and is time-consuming and labor-intensive, resulting in low grounding efficiency for the reinforcing bar as well. Therefore, we propose an assembly structure for a four-way three-dimensional reinforcing bar clamp. Utility Model Content

[0003] The technical problem this utility model aims to solve is to overcome the existing defects and provide an assembly structure for a four-way three-dimensional steel bar clamp. This device, through the assembled four-way three-dimensional steel bar clamp, can perform grounding connection operations on multiple steel bars. The device has a simple structural component, and only one person is needed to complete the steel bar grounding connection operation, effectively improving the device's own construction efficiency. At the same time, when grounding the steel bars, there is no need to cut off the steel bar connection nodes, making it more adaptable to various processes. The steel bar grounding assembly does not require a power supply or tooling, making the device applicable to a wider range of construction scenarios. Furthermore, the steel bar assembly nodes are all fixed with four bolts, resulting in high process tolerance and effectively solving the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an assembly structure for a four-way three-dimensional steel bar clamp, including a vertical clamp, a horizontal clamp installed on the lower side of the vertical clamp, a vertical clamp installed on the right side of the vertical clamp, and a longitudinal clamp installed on the right side of the vertical clamp. Semi-arc grooves are formed in the lower middle and right middle of the vertical clamp, the upper middle of the horizontal clamp, the left middle and right middle of the vertical clamp, and the left middle of the longitudinal clamp. A four-way steel bar is installed between each two adjacent semi-arc grooves. This device, through the assembled four-way three-dimensional steel bar clamp, can perform grounding connection operations on multiple steel bars. The device has a simple structural component, requiring only one person to complete the steel bar grounding connection operation, effectively improving the device's construction efficiency. Furthermore, when grounding steel bars, the device does not require cutting off the steel bar connection nodes, resulting in a wider range of process adaptability. The steel bar grounding assembly requires no power supply or tooling, making the device applicable to a wider range of construction scenarios. Moreover, the steel bar assembly nodes are all fixed with four bolts, providing high process tolerance.

[0005] Furthermore, four evenly distributed insertion holes are provided on the right and bottom walls of the vertical clamp and the left side of the longitudinal clamp. Four evenly distributed threaded holes are provided on the left and right sides of the vertical clamp and the upper side of the transverse clamp. Connecting bolts are inserted into the insertion holes. The end of the connecting bolt away from the adjacent insertion hole is threadedly connected to the adjacent threaded hole, thereby realizing the connection and fastening between the components in the assembly structure of the four-way three-dimensional steel reinforcement clamp.

[0006] Compared with the prior art, the beneficial effects of this utility model are as follows: The assembly structure of this four-way three-dimensional steel reinforcement clamp has the following advantages:

[0007] When using the rebar four-way three-dimensional clamp assembly structure to fix the rebar for grounding, the device, composed of vertical clamps, horizontal clamps, vertical clamps, and longitudinal clamps, can connect multiple rebars for grounding. The device has a simple structure and only requires one person to complete the rebar grounding connection work, effectively improving the device's construction efficiency. At the same time, due to its semi-arc groove design, there is no need to cut off the rebar connection nodes when grounding the rebar, making it more adaptable to various processes. The rebar grounding assembly does not require power supply or tooling, making the device applicable to a wider range of construction scenarios. Furthermore, the rebar assembly nodes are all fixed with four bolts, so even if one bolt is not tight enough, the predetermined assembly connection tightness can still be achieved, making the device highly tolerant of process errors.

[0011] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Please see Figure 1-2This embodiment provides a technical solution: an assembly structure for a four-way three-dimensional steel reinforcement clamp, including a vertical clamp 1, a horizontal clamp 2 installed on the lower side of the vertical clamp 1, a vertical clamp 3 installed on the right side of the vertical clamp 1, and a longitudinal clamp 4 installed on the right side of the vertical clamp 3. Semi-arc grooves 8 are formed in the lower middle and right middle of the vertical clamp 1, the upper middle of the horizontal clamp 2, the left middle and right middle of the vertical clamp 3, and the left middle of the longitudinal clamp 4. A four-way steel reinforcement 9 is installed between two adjacent semi-arc grooves 8. Four evenly distributed insertion holes 5 are formed on the right and bottom walls of the vertical clamp 1 and the left side of the longitudinal clamp 4. Four evenly distributed threaded holes 6 are formed on the left and right sides of the vertical clamp 3 and the upper side of the horizontal clamp 2. Each component is internally fitted with a connecting bolt 7. The end of each connecting bolt 7 furthest from the adjacent insertion hole 5 is threaded into the adjacent threaded hole 6. When using a steel four-way three-dimensional clamp to connect and fix different grounding steel bars, according to the actual grounding steel bar processing requirements, the horizontally arranged four-way steel bars 9 are inserted into the two lowest semi-circular grooves 8. Then, the worker inserts the four lowest connecting bolts 7 from top to bottom into the corresponding insertion holes 5, ensuring that the lower ends of these connecting bolts 7 are vertically aligned with the adjacent threaded holes 6. The worker then uses an electric wrench to rotate these four connecting bolts 7 sequentially. The connecting bolts 7 penetrate deeper into the corresponding threaded holes 6 through the threaded connection between their lower ends and the threaded holes 6, causing the horizontal clamp 2 to vertically approach the vertical clamp 1. The two semi-circular grooves 8 converge to assemble and fix the transversely arranged four-way reinforcing bars 9. The assembly and fixing parts are connected and fixed simultaneously using four connecting bolts 7. Even if one of the four connecting bolts 7 is not fully tightened, the clamping clamp can still achieve the set clamping force. The device has high process tolerance, and this step can be completed by only one worker, resulting in high construction efficiency. Subsequently, the worker uses the same principle to assemble and fix the vertically arranged four-way reinforcing bars 9 into the two semi-circular grooves 8 between the vertical clamping clamp 3 and the vertical clamping clamp 1, and assembles and fixes the longitudinally arranged four-way reinforcing bars 9 into the two semi-circular grooves 8 between the vertical clamping clamp 3 and the longitudinal clamping clamp 4. This achieves the grounding assembly and fixing of the corresponding four-way reinforcing bars 9 according to the actual situation, and the grounding reinforcing bars are grounded through the semi-circular grooves 8. The fixed, semi-circular groove 8 increases the conductive contact area and restricts the freedom of the reinforcing bar in all directions. This gives the entire three-dimensional four-way clamp a contact resistance no less than that of the original reinforcing bar, a high current carrying capacity, and a strong frictional force generated by the powerful clamping force, ensuring a secure fixation. During the grounding and fixing of the reinforcing bar, because the semi-circular groove 8 is penetrating, there is no need to cut off excess reinforcing bar at the grounding reinforcing bar node; the clamp can be directly connected. The assembly structure of this three-dimensional four-way reinforcing bar clamp has a wider range of process adaptability. The components of the entire device are already standardized during the production process and are not limited by power supply, auxiliary machinery, or tooling. Therefore, this clamp can be used for all-terrain and all-day construction operations. This device uses a four-way three-dimensional reinforcing bar clamp in an assembled combination form.This device can perform grounding connections on multiple reinforcing bars. Its simple structure allows for single-person operation, significantly improving construction efficiency. Furthermore, it eliminates the need to cut the reinforcing bar connection points, broadening its adaptability. The grounding assembly requires no power supply or tooling, expanding its application scenarios. All reinforcing bar assembly points are secured with four bolts, ensuring high tolerance for process errors.

[0013] The working principle of the assembly structure of the four-way three-dimensional steel reinforcement clamp provided by this utility model is as follows: When using the four-way three-dimensional steel reinforcement clamp to connect and fix different grounding steel bars, according to the actual processing requirements of the grounding steel bars, the horizontally arranged four-way steel bars 9 are clamped into the two bottom semi-circular grooves 8. Then, the worker inserts the four bottom connecting bolts 7 from top to bottom into the corresponding insertion holes 5, so that the lower ends of these connecting bolts 7 are vertically aligned with the adjacent threaded holes 6. Then, the worker uses an electric wrench to turn these four connecting bolts 7 in sequence. The connecting bolts 7 penetrate into the corresponding threaded holes 6 through the threaded connection between the lower end and the threaded hole 6, thereby causing the horizontal clamp 2 to move vertically closer to the vertical clamp 1. Through the mutual closing of the two bottom semi-circular grooves 8, the horizontally arranged four-way steel bars 9 are assembled and fixed. The assembly and fixing part of the device uses four connecting bolts 7 to connect and fix at the same time. Even if one of the four connecting bolts 7 is not tightened properly, the clamp can still achieve the set clamping force. The device process has high fault tolerance. This step can be completed by only one worker, which improves construction efficiency. Following this, the workers used the same principle to assemble and fix the vertically arranged four-way reinforcing bars 9 into the two semi-circular grooves 8 between the vertical clamp 3 and the vertical clamp 1, and to assemble and fix the longitudinally arranged four-way reinforcing bars 9 into the two semi-circular grooves 8 between the vertical clamp 3 and the longitudinal clamp 4. This allowed for the grounding assembly and fixing of the corresponding four-way reinforcing bars 9 according to the actual situation. The semi-circular grooves 8 fix the grounding reinforcing bars, increasing the conductive contact area and restricting the freedom of the reinforcing bars in all directions. This ensures that the entire three-dimensional four-way clamp has a contact resistance no less than that of the original reinforcing bars, a high current carrying capacity, and a strong frictional force due to the powerful clamping force, resulting in a secure fixation. During the grounding fixing process, because the semi-circular grooves 8 are penetrating, there is no need to cut off excess reinforcing bars at the grounding reinforcing bar nodes; they can be directly connected using clamps. The assembly structure of this three-dimensional four-way reinforcing bar has a wider range of process adaptability. Since all components of the device are pre-designed during production, they are not limited by power supply, auxiliary machinery, or tooling. Therefore, this clamp can be used for all-terrain and all-day construction operations.
