Description

Technical Field

[0001] This utility model relates to the field of steel structure manufacturing technology, and in particular to a clamping bracket for steel structure welding. Background Technology

[0002] Steel structures are widely used in various engineering projects such as high-rise buildings, large-span stadiums, and bridges due to their significant advantages such as high strength, light weight, short construction period, and good seismic performance.

[0003] Common steel beams in steel structures include shaped steel beams (such as I-beams and H-beams) and composite beams (made of welded or riveted steel plates). In actual construction, welded connections are typically used to connect adjacent steel beams because they offer advantages such as good connection performance, high strength, and good sealing.

[0004] In actual construction, in order to meet the height requirements of the building, multiple steel beams are usually connected end to end to form a long vertical beam, or in order to meet the span requirements, multiple steel beams can be connected end to end to form a horizontal beam. In addition, the processed steel beams need to be connected and spliced ​​to form a steel structure.

[0005] Due to the large weight of the steel beams, welding them typically requires using cranes and cables to lift them. The beams are then precisely aligned with another beam using traction ropes or other auxiliary tools. During this process, the rigidity of the cables and the weight of the steel beams make it difficult for workers to adjust the position of adjacent beams as needed, thus hindering the proper alignment of them.

[0006] Furthermore, during the welding process, the suspended steel structural components are prone to swaying or displacement due to thermal stress and human error. This not only reduces welding precision, causing quality problems such as weld deviations and incomplete welds, but may also lead to welding interruptions, requiring rework, thus extending the construction period and increasing construction costs. For example, in the welding construction of some high-rise steel structures, the stability issues of hoisting make it difficult to guarantee welding quality, posing a potential threat to structural safety. Utility Model Content

[0007] The purpose of this invention is to provide a clamping bracket for steel structure welding, which aims to improve the problem that it is inconvenient to adjust the state of the steel beam according to the needs when it is lifted for welding, and that this affects the welding process.

[0008] To achieve the above objectives, the solution adopted by this utility model is as follows:

[0009] A clamping bracket for welding steel structures includes adjacent I-beams, with sleeve frames fitted onto each adjacent I-beam, and support frames provided on the outer side of the sleeve frames. Two sets of support frames are connected and installed on the same connecting frame. The sleeve frame includes two sets of symmetrically arranged splicing plates, and the central cross-section formed by splicing the two sets of splicing plates is the same as the cross-section of the I-beam. The support frame includes a first arc plate and a second arc plate, which are bolted together and installed on the outer side of the two sets of splicing plates.

[0010] Furthermore, snap-fit ​​grooves are provided on the inner sidewalls of both the first and second arc-shaped plates. The ends of the snap-fit ​​grooves are set to be open, and the two snap-fit ​​grooves distributed vertically are arranged to communicate with each other.

[0011] Furthermore, a snap-on sliding plate is fixedly installed on the outer side of the splicing plate. The cross-section of both the snap-on sliding plate and the snap-on sliding groove is set as a convex structure, and the snap-on sliding plate is installed in the snap-on sliding groove.

[0012] Furthermore, multiple grooves are provided on the outer surface of the snap-on slide plate, and the multiple grooves are distributed along the arc length direction of the snap-on slide plate. Each groove is provided along the thickness direction of the snap-on slide plate. Bolts are threaded through the side walls of the first arc plate and the second arc plate, and the ends of the bolts are inserted into a certain groove.

[0013] Furthermore, two end plates are fixedly installed at the bottom of the second arc-shaped plate, and a connecting column is installed between the two end plates. Polygonal holes are provided through the connecting column and the end plates, and a connecting shaft is provided through the space formed by the polygonal holes.

[0014] Furthermore, each side wall of the connecting shaft is provided with a threaded groove, and a bolt is provided through a certain end plate, with the end of the bolt threaded into a certain threaded groove; a connecting plate is fixedly provided on the side of the connecting column, and the end of the connecting plate away from the connecting column is set as an opening.

[0015] Furthermore, the connecting frame is configured as a first connecting frame, which includes a base, a support plate, and a first insert plate. The base and the support plate are configured as T-shaped structures of different sizes, and the support plate is fixedly installed on the top of the base. There are two first insert plates, and the two first insert plates are fixedly installed on both sides of the support plate, while the first insert plates are located on the same surface. The connecting plate is fitted to the support plate, and the first insert plate is inserted into the connecting plate.

[0016] Furthermore, the connecting frame is configured as a second connecting frame, which includes a main pipe, a second insert plate, and a baffle. Two second insert plates are fixedly installed on two mutually perpendicular surfaces of the main pipe. The baffle is configured as an L-shaped structure, and the main pipe is installed at the right angle of the baffle. The connecting plate is set to fit against the baffle, and the second insert plate is inserted into the connecting plate.

[0017] Furthermore, a braking mechanism is provided below the horizontally placed splicing plate. The braking mechanism includes a support frame, a threaded column, and a brake disc. The top of the support frame is connected to the ear plate of the splicing plate. The threaded column is threaded through the bottom of the support frame, and the brake disc is installed at the end of the threaded column.

[0020] 1. This utility model sets up a sleeve frame and a support frame, and both the sleeve frame and the support frame are set as detachable splicing structures. At the same time, the sleeve frame is sleeved on the steel beam. In addition, the sleeve frame can rotate relative to the support frame. Therefore, the state of the steel beam can be adjusted according to the needs during welding, so that adjacent steel beams are aligned, avoiding the current situation where it is inconvenient to adjust the state of the steel beam when it is suspended.

[0021] 2. By setting a connecting column, which is connected between two end plates via a connecting shaft, this utility model can control the stable installation of the connecting plate relative to the support frame. At the same time, the detachable connecting shaft removes the restriction of the connecting column and end plates, providing convenience for adjusting the orientation of the connecting plate, so that the connecting plate can be connected to different frames to stabilize the steel beams in different relationships.

Detailed Implementation

[0035] 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.

[0036] Example 1: In order to facilitate the adjustment of the state of the steel beams when welding adjacent steel beams and to control the relative stability of the adjacent steel beams, this example provides a bracket for steel structure welding. The bracket is fitted on the steel beams, and the adjacent steel beams are controlled to be placed stably under the action of the bracket.

[0037] like Figure 1 , Figure 7As shown, specifically, the support structure includes a sleeve frame 4, a support frame 2, and a connecting frame. Both the sleeve frame 4 and the support frame 2 are detachable splicing structures, with the support frame 2 fitted onto the outside of the sleeve frame 4. The support frame 2 can rotate relative to the sleeve frame 4. Therefore, after the sleeve frame 4 is fitted onto a steel beam (such as an I-beam 1), the support frame 2 can stably support the steel beam, and the rotation of the sleeve frame 4 can be controlled to adjust the state of the steel beam. To ensure the relative stability of adjacent steel beams, a connecting frame is installed on the sides of the two sets of support frames 2, controlling the relative position of the two sets of support frames 2, thereby forcing the adjacent steel beams to be placed stably.

[0038] like Figure 6 As shown, to achieve the splicing and connection of the sleeve frame 4, the sleeve frame 4 includes two sets of symmetrically arranged splicing plates 41. The central cross-section formed by the splicing of the two sets of splicing plates 41 is the same as the cross-section of the I-beam 1, or the central cross-section formed by the splicing of the two sets of splicing plates 41 is set as a rectangular structure. In short, it should be convenient for the I-beam 1 to pass through. In order to control the relative stable placement of the two sets of splicing plates 41, insert posts 45 and slots are respectively provided on the sides of the two sets of splicing plates 41 that are in contact with each other. The insert posts 45 are inserted into the slots. Therefore, with the cooperation of the insert posts 45 and the slots, the two sets of splicing plates 41 can move relative to each other in their axial direction.

[0039] like Figure 5 As shown, in order to connect the support frame 2, the support frame 2 includes a first arc plate 21 and a second arc plate 23. The ends of the first arc plate 21 and the second arc plate 23 are provided with through holes, and bolts are installed through the through holes. Therefore, the first arc plate 21 and the second arc plate 23 are connected by bolts and installed on the outside of the sleeve frame 4.

[0040] like Figure 5 , Figure 6 As shown, in order to connect the splicing plate 41 to the curved plate and to control the movement of the splicing plate 41 relative to the curved plate as needed, snap-fit ​​grooves 22 are provided on the inner sidewalls of both the first curved plate 21 and the second curved plate 23. The ends of the snap-fit ​​grooves 22 are open, and the two snap-fit ​​grooves 22 distributed vertically are arranged opposite each other. A snap-fit ​​sliding plate 42 is fixedly provided on the outer side of the splicing plate 41. Both the snap-fit ​​sliding plate 42 and the snap-fit ​​groove 22 have convex cross-sections, and the snap-fit ​​sliding plate 42 is installed in the snap-fit ​​groove 22. Therefore, with the cooperation of the snap-fit ​​sliding plate 42 and the snap-fit ​​groove 22, the splicing plate 41 and the curved plate are stably connected, and the snap-fit ​​sliding plate 42 can move within the snap-fit ​​groove 22 to achieve the rotation of the splicing plate 41. To reduce the resistance of the relative movement between the snap-on sliding plate 42 and the curved plate, the sidewalls of the snap-on sliding groove 22 and the snap-on sliding plate 42 can be polished, or a metal coating with a low coefficient of friction, such as chromium or nickel, can be plated on their surfaces.

[0041] like Figure 6As shown, in order to control the rotation of the splicing panel 41, a handle 44 is provided on the side of the splicing panel 41, and the operator can hold the handle 44 to force the splicing panel 41 to rotate.

[0042] like Figure 5 , Figure 6 As shown, to ensure the stable placement of the rotated splicing plate 41, multiple grooves 43 are provided on the outer surface of the snap-fit ​​sliding plate 42. These grooves 43 are distributed along the arc length of the snap-fit ​​sliding plate 42, and each groove 43 is positioned along the thickness direction of the snap-fit ​​sliding plate 42. Bolts are threaded through the side walls of both the first arc-shaped plate 21 and the second arc-shaped plate 23, with the ends of the bolts inserted into a specific groove 43. Therefore, when it is necessary to rotate the splicing plate 41, rotating the bolts releases the restriction between the splicing plate 41 and the arc-shaped plate, allowing the operator to rotate the splicing plate 41. After the splicing plate 41 rotates, rotating the bolts in the opposite direction allows their ends to extend into the grooves 43, thereby ensuring the relatively stable installation of the splicing plate 41 and the arc-shaped plate.

[0043] like Figure 5 As shown, in order to adjust the relative positions of the two sets of components consisting of the support frame 2 and the sleeve frame 4 as needed, so that the two sets of components are on the same plane or perpendicular to each other, two end plates 24 are fixedly installed at the bottom of the second arc-shaped plate 23. A connecting column 25 is provided between the two end plates 24, and a connecting plate 28 is fixedly installed on the side of the connecting column 25. The connecting plates 28 of the two sets of supports are connected to the connecting frame. Therefore, with the cooperation of the connecting frame and the connecting plate 28, the two sets of components can be controlled to be installed relatively stably. In addition, polygonal holes 27 are provided through the connecting column 25 and the end plate 24. A polygonal structure connecting shaft 26 is provided through the space formed by the polygonal holes 27. With the cooperation of the connecting shaft 26 and the polygonal holes 27, the connecting column 25 can be controlled to be installed stably and statically relative to the end plate 24. When it is necessary to adjust the relative position of two sets of components so that they are on the same plane or perpendicular to each other, the connecting shaft 26 can be detached, and the connecting column 25 and the connecting plate 28 can be rotated to adjust the orientation of the connecting plate 28, thereby adjusting the relative position of the two sets of components.

[0044] To ensure stable installation of the coupling 26 relative to the end plate 24, threaded grooves are provided on each side wall of the coupling 26, and a bolt is installed through one of the end plates 24. The threaded end of the bolt is inserted into a threaded groove. Therefore, after adjusting the orientation of the connecting plate 28, the coupling 26 and the end plate 24 can be connected by bolts to restrict the position of the coupling 26.

[0045] like Figure 3As shown, to stably support the steel beams that are aligned in a straight line, a first connecting frame 3 is used. The first connecting frame 3 includes a base 31, a support plate 32, and a first insert plate 33. The base 31 and the support plate 32 are T-shaped structures of different sizes, with the support plate 32 fixedly mounted on the top of the base 31. Two first insert plates 33 are provided, fixedly mounted on opposite sides of the support plate 32, and located on the same plane. A connecting plate 28 is fitted against the support plate 32, with an open end away from the connecting column 25. Therefore, the first insert plate 33 is inserted into the connecting plate 28, and then bolts are used to connect the connecting plate 28 and the first insert plate 33. Utilizing the structural characteristics of the support plate 32, the two connecting plates 28 can be stably positioned on the same plane, thus supporting the support frame 2 and the sleeve frame 4 on the same axis, achieving support for the steel beams aligned in a straight line.

[0046] Example 2: Figure 10 As shown, based on Embodiment 1, to constrain the steel beams that are in a mutually perpendicular relationship, a second connecting frame 5 is configured. The second connecting frame 5 includes a main pipe 51, a second insert plate 52, and a baffle 53. Two second insert plates 52 are fixedly installed on two mutually perpendicular surfaces of the main pipe 51. The baffle 53 is configured with an L-shaped structure, and the main pipe 51 is installed at the right angle of the baffle 53. A connecting plate 28 is set against the baffle 53, and the end of the connecting plate 28 away from the connecting column 25 is set as an opening, so the second insert plate 52 is inserted into the connecting plate 28. Then, the connecting plate 28 and the first insert plate 33 are connected by bolts. Utilizing the structural characteristics of the second connecting frame 5, the two connecting plates 28 can be stably positioned in a vertical relationship. Then, the support frame 2 and the sleeve frame 4 are perpendicular to each other, thus achieving support for the mutually perpendicular steel beams.

[0047] like Figure 8 As shown, in order to increase the resistance to the relative movement of the sleeve frame 4 and the vertical beam, an anti-slip layer can be provided on the inner side wall of the sleeve frame 4, and a braking mechanism 6 can be provided below the sleeve frame 4. The braking mechanism 6 contacts the steel beam to increase the resistance to the relative movement of the sleeve frame 4 and the steel beam.

[0048] like Figure 9 , Figure 11 As shown, specifically, the braking mechanism 6 includes a support frame 61, a threaded post 63, and a brake disc 62. The top of the support frame 61 is connected to the ear plate 46 of the splicing plate 41. The threaded post 63 is threaded through the bottom of the support frame 61. The brake disc 62 is installed at the end of the threaded post 63, and an anti-slip layer is provided on the side wall of the brake disc 62. Therefore, rotating the threaded post 63 can control the movement of the brake disc 62, so that the brake disc 62 is fitted to the steel beam, increasing the resistance of the sleeve frame 4 sliding down.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. It should be noted that for those skilled in the art, any changes, modifications or additions without departing from the concept of the present utility model should fall within the protection scope of the present utility model.
