Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure production technology, specifically a multi-angle rapid positioning auxiliary structure for splicing square steel. Background Technology
[0002] In construction, machinery manufacturing, and steel structure engineering, square steel is a commonly used building and structural material. Square steel is a solid, long strip of steel with a square cross-section, belonging to the category of bar stock, distinct from hollow square tubes. The quality of its splicing process directly affects project quality and construction efficiency. Currently, the splicing process of square steel often faces problems such as difficulty in positioning and inconvenience in angle adjustment. Traditional splicing methods often use simple clamps or manual assistance for positioning, which not only makes it difficult to quickly achieve precise splicing at multiple angles, but also makes it prone to displacement and swaying during the splicing process, resulting in large splicing errors and low efficiency. Furthermore, existing auxiliary structures cannot flexibly adjust the support according to the length of the square steel, and have poor applicability to square steel of different specifications. Therefore, this paper proposes a splicing auxiliary structure that can achieve rapid multi-angle positioning, adjustable support, and protection of the square steel surface to overcome the shortcomings of existing technologies. Summary of the Invention
[0003] The main purpose of this utility model is to solve the above-mentioned existing technical problems and provide a multi-angle rapid positioning auxiliary structure for splicing square steel.
[0004] The specific solution of this utility model is as follows: a multi-angle rapid positioning auxiliary structure for splicing square steel includes a first clamping plate and a second clamping plate, which are hinged together. A first bolt is installed on each of the first and second clamping plates. A connecting rod is rotatably connected to the surface of the second clamping plate. A slot is opened along the length direction on the surface of the connecting rod. A screw is provided on the surface of the first clamping plate. The other end of the screw passes into the slot and is threaded with a fastening nut. When the second clamping plate rotates relative to the first clamping plate, the screw moves along the slot. A support structure is installed at the bottom of the second clamping plate. The support structure is used to adjust the support according to the length of the square steel.
[0005] According to the above technical solution, rapid multi-angle adjustment is achieved by using a hinged clamp plate and a connecting rod screw. The square steel is fixed with bolts and a U-shaped clamp plate. The adjustable support structure can adapt to square steel of different lengths. At the same time, rubber blocks protect the surface of the square steel, effectively improving splicing efficiency, accuracy, stability and applicability.
[0006] Furthermore, the support structure includes a support base plate, which is slidably installed on the bottom end of the second clamping plate. Side plates are installed on both sides of the top of the support base plate, and second bolts are threadedly connected to the two side plates. The second bolts are used to clamp the square steel.
[0007] According to the above technical solution, the support base plate can be slidably installed at the bottom of the second clamping plate, and with the side plates with second bolts on both sides of the top, it can be adjusted to accommodate square steel of different lengths by sliding, and the second bolts are used to firmly clamp the square steel, thereby enhancing the stability of the bottom support when the square steel is spliced.
[0008] Furthermore, the first and second clamping plates have a U-shaped structure, and the first bolt is used to fix the square steel in the groove.
[0009] According to the above technical solution, the first and second clamping plates adopt a U-shaped structure design and cooperate with the first bolt to tightly wrap the square steel from three sides, increase the contact area between the clamping plates and the square steel, form a stable clamping effect, and effectively limit the displacement and shaking of the square steel during the splicing process.
[0010] Furthermore, a rubber block is installed at the bottom of the first bolt to prevent scratches on the surface of the square steel.
[0011] According to the above technical solution, the rubber block installed at the bottom of the first bolt forms a buffer layer due to its softness when the square steel is tightened by the bolt. This prevents the metal bolt from directly contacting the surface of the square steel, effectively preventing the square steel from being scratched or worn during the fixing process. This protects the integrity and aesthetics of the square steel surface, ensures that the performance of the square steel is not affected, and improves the quality of the finished product after the square steel is spliced.
[0012] Furthermore, both the first and second clamping plates are made of high-strength alloy steel to improve their strength and wear resistance.
[0013] According to the above technical solution, the first and second clamping plates are made of high-strength alloy steel, which significantly enhances the deformation resistance and load-bearing strength of the clamping plates due to their excellent mechanical properties.
[0014] Compared with the prior art, this utility model has the following advantages: The multi-angle rapid positioning auxiliary structure for square steel splicing achieves rapid and accurate positioning from multiple angles through the hinge of the first and second clamping plates and the cooperation of components such as connecting rods and screws, effectively reducing splicing errors; the adjustable support base plate and the second bolt on the side plate in the support structure can flexibly adjust the support according to the length of square steel of different specifications, significantly improving the versatility of the auxiliary structure; the rubber block at the bottom of the first bolt prevents the surface of the square steel from being scratched, ensuring the quality of the project; the clamping plates made of high-strength alloy steel enhance the structural strength and wear resistance, improve the splicing stability, and combined with the multi-angle rapid positioning and adjustable support characteristics, reduce repetitive operations and greatly improve construction efficiency.

[0020] See Figure 1-4 This embodiment is a multi-angle rapid positioning auxiliary structure for splicing square steel, including a first clamping plate 1 and a second clamping plate 2, which are hinged together. A first bolt 3 is threaded onto each of the first clamping plate 1 and the second clamping plate 2. A connecting rod 4 is rotatably connected to the surface of the second clamping plate 2. A slot 5 is opened along the length direction on the surface of the connecting rod 4. A screw 6 is welded to the surface of the first clamping plate 1. The other end of the screw 6 passes through the slot 5 and is threaded to a fastening nut 7. When the second clamping plate 2 rotates relative to the first clamping plate 1, the screw 6 moves along the slot 5. A support structure is installed at the bottom of the second clamping plate 2. The support structure is used to adjust the support according to the length of the square steel.
[0021] Furthermore, the support structure includes a support base plate 8, which is slidably installed on the bottom end of the second clamping plate 2. A side plate 9 is welded to each side of the top of the support base plate 8, and a second bolt 10 is threaded onto the surface of each of the two side plates 9. The second bolt 10 is used to clamp the square steel between the two side plates 9.
[0022] Furthermore, the first clamping plate 1 and the second clamping plate 2 have a U-shaped structure, and the first bolt 3 is used to fix the square steel in the groove.
[0023] Furthermore, a rubber block 11 is installed at the bottom of the first bolt 3, which is used to prevent the surface of the square steel from being scratched.
[0024] Furthermore, both the first clamping plate 1 and the second clamping plate 2 are made of high-strength alloy steel to improve the strength and wear resistance of the clamping plates.
[0025] The working principle of this embodiment is as follows: When the multi-angle rapid positioning auxiliary structure for square steel splicing is working, the square steel to be spliced is first placed in the U-shaped groove of the first clamping plate 1 and the second clamping plate 2. By screwing the first bolt 3 on the first clamping plate 1 and the second clamping plate 2, the rubber block 11 at the bottom of the bolt contacts the surface of the square steel, applying a tightening force while preventing scratches on the surface of the square steel, thus achieving initial fixation of the square steel. When it is necessary to adjust the splicing angle, the operator rotates the second clamping plate 2. The second clamping plate 2 rotates around the hinge point, driving the connecting rod 4 connected to it to move. At this time, the screw 6 on the first clamping plate 1 slides along the slot 5 on the surface of the connecting rod 4. After adjusting to the required angle, the screw 6 is fixed in the corresponding position of the slot 5 by tightening the fastening nut 7, thereby accurately locking the included angle between the first clamping plate 1 and the second clamping plate 2, completing the multi-angle rapid positioning. In terms of support, based on the actual length of the square steel, the support base plate 8 at the bottom of the second clamping plate 2 is slidably adjusted to extend it to the appropriate position. Then, the second bolts 10 on the side plates 9 on both sides of the top of the support base plate 8 are tightened. The second bolts 10 on both sides form a clamping force on the square steel, providing stable and reliable support from the bottom, ensuring that the square steel remains stable during the splicing process, avoiding shaking and displacement, and ultimately achieving efficient and precise operation of multi-angle splicing of square steel.
