Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure welding technology, and more specifically, to a high-efficiency welding auxiliary support for steel structure beam-column joints. Background Technology
[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are primarily composed of steel beams, columns, trusses, and other components made of shaped steel and steel plates, and are treated with rust removal and prevention processes such as silanization, pure manganese phosphating, washing and drying, and galvanizing. The components are typically connected by welds, bolts, or rivets.
[0003] A search revealed Chinese patent application number 202321791856.6, which discloses an auxiliary connection fixture for prefabricated steel structure beams and columns, used for auxiliary positioning during the installation of beams and columns. The fixture includes a base frame fitted onto the column, a horizontal adjustment component, a clamping component, and a vertical adjustment component. The horizontal adjustment component is movably mounted on the base frame, with one end connected to the clamping component. One end of the vertical adjustment component is connected to the base frame, and the other end is connected to the beam. When installing the beam between columns, this utility model first clamps and fixes the device to the column using a clamping part formed between the base frame and the connecting plate, positioning it below the point where the beam and column need to be joined. This allows the beam to be lifted by a crane, with its end placed on a positioning support and positioned by a positioning groove. This prevents external airflow from causing the beam to sway and thus ensuring accurate alignment with the column. However, the aforementioned patents have the following shortcomings: the positioning groove on the positioning platform is a fixed structure, which cannot be used for beams of different widths. Furthermore, the positioning platform lacks a lateral fixing structure, so the beam may move when subjected to horizontal wind forces or construction collisions, affecting the stability and accuracy of the welding operation. Therefore, this utility model proposes a new solution. Utility Model Content
[0004] The purpose of this utility model is to solve the problems that the positioning groove on the positioning support of the above-mentioned patent is a fixed structure, which cannot be used for beams of different widths. Moreover, the positioning support does not have a lateral fixing structure. When subjected to horizontal wind force or construction collision, the beam will move, affecting the stability and accuracy of the welding operation. Therefore, this utility model proposes a high-efficiency welding auxiliary support for steel structure beam-column joints.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] Highly efficient welding auxiliary supports for steel structure beam-column joints are proposed to improve the above-mentioned problems.
[0007] The present invention is as follows:
[0008] The device includes a base frame mounted on a column, a horizontal adjustment assembly, a clamping assembly, and a vertical adjustment assembly. The vertical adjustment assembly includes a support plate and a lead screw connected to the base frame. A sliding block that cooperates with the lead screw is installed through the center of the support plate. A positioning bracket for supporting a crossbeam is rotatably connected to the top of the lead screw.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] In the solution of this utility model:
[0016] 1. By setting the first limiting plate, the second limiting plate, the adjusting screw hole and the bolt, the position of the first limiting plate and the second limiting plate on the positioning support can be adjusted during use, so that the width of the positioning groove can be flexibly adjusted according to the width of the crossbeam, thereby facilitating the use with crossbeams of different widths and improving the overall versatility.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.
[0026] like Figures 1-5 As shown, this embodiment proposes a high-efficiency welding auxiliary support for steel structure beam-column joints, including a base frame 3 sleeved on the column 1, a horizontal adjustment component 5, a clamping component 4, and a vertical adjustment component. The vertical adjustment component includes a support plate 6 and a lead screw 9 connected to the base frame 3. A sliding block that cooperates with the lead screw 9 is installed through the center of the support plate 6. The top of the lead screw 9 is rotatably connected to a positioning support 7 for supporting the crossbeam 2. A first limiting plate 10 and a second limiting plate 11 are symmetrically arranged on the top of the positioning support 7. The first limiting plate 10, the second limiting plate 11, and the positioning support 7 form a positioning groove for limiting the position of the crossbeam 2. Bolts 13 are threadedly connected to both the first limiting plate 10 and the second limiting plate 11. Multiple adjusting screw holes 12 that cooperate with the bolts 13 are opened through the positioning support 7. The positioning plate 11, adjusting screw hole 12, and bolt 13 allow for adjustment of the position of the first limiting plate 10 and the second limiting plate 11 on the positioning support 7 during use. This enables flexible adjustment of the width of the positioning groove according to the width of the crossbeam 2, facilitating use with crossbeams 2 of different widths and improving overall versatility. The outer walls of both the first limiting plate 10 and the second limiting plate 11 are fixedly connected to brackets 14 located above the bolt 13. Fixing components 15 for fixing the crossbeam 2 are threaded onto the brackets 14. By setting up the brackets 14 and fixing components 15, the two symmetrically arranged fixing components 15 can clamp and fix the crossbeam 2 from both sides during use, effectively preventing displacement of the crossbeam 2 due to wind or collision during welding. This significantly improves the stability of the crossbeam 2 and better ensures the progress of welding work.
[0027] like Figures 1-3 As shown, in a preferred embodiment, based on the above method, the fixing component 15 further includes a threaded rod 151 threadedly connected to the bracket 14. One end of the threaded rod 151 is fixedly connected to a turntable 152, and the other end of the threaded rod 151 is fixedly connected to a first pad 153. It should be noted that during use, rotating the turntable 152 can quickly adjust the extension length of the threaded rod 151 to achieve lateral clamping of the crossbeam 2. The first pad 153 is made of rubber, which can increase friction to prevent the crossbeam 2 from sliding and avoid damage to the surface of the crossbeam 2 caused by rigid contact.
[0028] like Figures 1-3As shown, in a preferred embodiment, based on the above method, further, guide rods 16 are fixedly connected to the bottom of the positioning platform 7 on both sides of the lead screw 9. A locking mechanism 17 cooperating with the guide rods 16 is fixedly connected to the bottom of the support plate 6. The guide rods 16 pass through the support plate 6 and the locking mechanism 17, and are slidably connected to both. It should be noted that the guide rods 16 can guide the positioning platform 7 when it moves. Through the locking mechanism 17, the guide rods 16 can be locked after the position of the positioning platform 7 is adjusted, thereby sharing the force on the lead screw 9 with the guide rods 16, effectively extending the service life of the lead screw 9.
[0029] like Figures 1-3 As shown, in a preferred embodiment, based on the above method, a pad 8 is further fixedly connected to the inner wall of both the first limiting plate 10 and the second limiting plate 11. It should be noted that by setting the pad 8, the friction between the first limiting plate 10 and the second limiting plate 11 and the surface of the crossbeam 2 can be increased, and the crossbeam 2 can also be prevented from directly contacting the first limiting plate 10 and the second limiting plate 11 and causing wear.
[0030] like Figures 1-5 As shown, in a preferred embodiment, based on the above method, the locking mechanism 17 further includes a sleeve 171 fixedly connected to the bottom of the support plate 6. A compression cylinder 172 is threadedly connected to the outer side of the sleeve 171. A plurality of evenly distributed clamping blocks 173 are rotatably mounted on the sleeve 171. A second pad 176 is fixedly connected to the inner wall of the clamping block 173. An installation groove 175 for mounting on the clamping block 173 is provided on the sleeve 171. Two crossbars 174 are symmetrically connected to the side wall of the clamping block 173. A groove 177 that cooperates with the crossbars 174 is provided on the side wall of the installation groove 175. The clamping block 173 is rotatably connected to the sleeve 171 through the crossbars 174 and the groove 177. It should be noted that when in use, rotating the extrusion cylinder 172 located outside the sleeve 171 can press the clamping block 173, which is rotatably installed inside the mounting groove 175, into the inside of the sleeve 171, thereby clamping and fixing the guide rod 16 through multiple clamping blocks 173 in conjunction with the second pad 176.
[0031] Specifically, the working principle of the high-efficiency welding auxiliary support for the steel structure beam-column joint is as follows: During use, the base frame 3 is fixed to the outside of the column 1 through the horizontal adjustment component 5 and the clamping component 4. Then, the height of the positioning support 7 is adjusted by the screw 9 and the slider so that it can support the crossbeam 2. Then, the distance between the first limiting plate 10 and the second limiting plate 11 is adjusted by adjusting the screw hole 12 and the bolt 13 so that the positioning groove can match the width of the crossbeam 2. When the crossbeam 2 is placed inside the positioning groove, the fixed component 15 connected by the thread on the rotating support 14 cooperates with the support 14 to clamp and fix it from both sides of the crossbeam 2. After the fixing is completed, the column 1 and the crossbeam 2 are welded.
[0032] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
