Description

Technical Field

[0001] This utility model relates to the field of H-beam welding technology, specifically to an anti-deformation structure for welding the end plates of ribbed H-beam structures. Background Technology

[0002] H-beams are a type of steel structure. They are an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. They are named for their cross-section resembling the letter "H". Because all parts of an H-beam are arranged at right angles, it has advantages such as strong bending resistance in all directions, simple construction, cost savings, and light structural weight, and has been widely used. H-beams are frequently used, especially in the welding process of steel structure beams. Therefore, the welding technology of H-beam structural beams has a significant impact on the strength of the steel structure beams.

[0003] The published patent document CN217965418U discloses an anti-deformation structure for welding end plates of H-beams. This patent document uses a support block, neodymium magnets, diagonal bracing arms, threaded rods, clamping plates, locking plates, connecting bolts, and tightening bolts. During use, the locking plates are fixed to the steel columns by the tightening bolts, and connected to the support block by the connecting bolts. The upper and lower end plates are respectively fixed by neodymium magnets on the upper and lower sides of the support block. After moving the triangular plate to the welding position of the upper and lower end plates, rotating the threaded rod allows the clamping plates to move obliquely, thus obliquely pressing and fixing the triangular plate. This creates a unified positioning and fixing effect for the triangular plate, upper end plate, and lower end plate, ensuring the relative positioning accuracy of the upper and lower end plates and preventing displacement and deformation during welding, thus guaranteeing the installation accuracy of the H-beam. However, the aforementioned patent document cannot guarantee the flatness of the H-beam, making it prone to deformation after welding. Utility Model Content

[0004] The purpose of this invention is to provide an anti-deformation structure for welding the end plates of ribbed H-shaped steel beams, thus solving the problems mentioned in the background art.

[0005] This application provides an anti-deformation structure for welding end plates of ribbed H-shaped steel beams, including an H-shaped steel column and an H-shaped steel beam. Two inter-rib stiffening plates are welded through and onto the H-shaped steel column. The H-shaped steel beam is positioned in front of the two inter-rib stiffening plates and is adapted to fit them. An anti-deformation auxiliary assembly is provided between the inter-rib stiffening plates and the H-shaped steel beam. The anti-deformation auxiliary assembly includes two auxiliary support plates and two cylinders. The two auxiliary support plates are positioned at the top of one inter-rib stiffening plate and the bottom of the other inter-rib stiffening plate, and each auxiliary support plate has two threaded holes. The two cylinders are positioned on both sides between the two auxiliary support plates, and turntables are rotatably mounted at the top and bottom of each cylinder. Threaded shafts matching the threaded holes are welded onto the turntables, and the ends of the threaded shafts pass through the threaded holes.

[0006] Optionally, a beam-column connecting Y-shaped plate is welded between the two stiffening plates. The H-beam is adapted to the beam-column connecting Y-shaped plate, and the rear end of the H-beam is inside the beam-column connecting Y-shaped plate. Three through holes are provided on both sides of the beam-column connecting Y-shaped plate. Three high-strength bolts matching the through holes are threaded through the H-beam and threaded onto it. Matching nuts are fitted on the high-strength bolts.

[0007] Optionally, the thread helix angle of the threaded shaft is less than the equivalent friction angle.

[0008] Optionally, the outer wall of the turntable is provided with a plurality of internal grooves at equal intervals.

[0009] Optionally, a matching washer is fitted onto the high-strength bolt.

[0010] Optionally, the rear side of the beam-column connecting Y-shaped plate is welded to the H-shaped steel column.

[0011] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows: 1. The technical solution of this application, through the cooperation of the anti-deformation auxiliary components consisting of auxiliary support plate, cylinder, threaded hole, turntable, inner groove and threaded shaft, and the inter-rib stiffening plate, can ensure the flatness between the H-beam and the inter-rib stiffening plate, and prevent deformation of the H-beam and the inter-rib stiffening plate during and after welding.

[0012] 2. The technical solution of this application facilitates the installation between the H-beam and the beam-column connecting Y-shaped plate through the use of stiffening plates between ribs, Y-shaped plates connecting beams and columns, through holes, H-beams, high-strength bolts, nuts and washers, thereby further increasing the stability of the H-beam.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] Please see Figure 1-2 This utility model provides an anti-deformation structure for welding the end plates of ribbed H-shaped steel beams, including an H-shaped steel column 1 and an H-shaped steel beam 2. Two inter-rib stiffening plates 4 are welded through and welded to the H-shaped steel column 1. The H-shaped steel beam 2 is located on the front side of the two inter-rib stiffening plates 4 and is adapted to the inter-rib stiffening plates 4. An anti-deformation auxiliary component 3 is provided between the inter-rib stiffening plates 4 and the H-shaped steel beam 2. The anti-deformation auxiliary component 3 includes two auxiliary support plates 31 and two cylinders 32. The two auxiliary support plates 31 are located at the top of one inter-rib stiffening plate 4 and the bottom of the other inter-rib stiffening plate 4, and two threaded holes 33 are opened on the auxiliary support plates 31. The two cylinders 32 are located on both sides between the two auxiliary support plates 31, and a turntable 34 is rotatably installed on the top and bottom of the cylinders 32. A threaded shaft 35 matching the threaded hole 33 is welded on the turntable 34, and the end of the threaded shaft 35 passes through the threaded hole 33. In this technical solution, by placing two auxiliary support plates 31 between two interrib stiffening plates 4, rotating the turntable 34 to make the threaded shaft 35 pass through the corresponding threaded holes 33, thereby adjusting the distance between the two auxiliary support plates 31 until the two auxiliary support plates 31 and the two interrib stiffening plates 4 come into contact and abut each other, the flatness between the H-beam 2 and the interrib stiffening plates 4 can be guaranteed, and deformation of the H-beam 2 and the interrib stiffening plates 4 during and after welding can be prevented. After the partial welding between the H-beam 2 and the interrib stiffening plates 4 is completed, the anti-deformation auxiliary component 3 can be removed to weld the remaining part of the H-beam 2 and the interrib stiffening plates 4.

[0017] In some technical solutions, such as Figure 1 , Figure 3 and Figure 4 As shown, a beam-column connecting Y-shaped plate 5 is welded between the two inter-rib stiffening plates 4. The H-beam 2 is adapted to the beam-column connecting Y-shaped plate 5, and the rear end of the H-beam 2 is inside the beam-column connecting Y-shaped plate 5. Three through holes 6 are opened on both sides of the beam-column connecting Y-shaped plate 5. Three high-strength bolts 7 that match the through holes 6 are threaded through and connected to the H-beam 2. Matching nuts 8 are fitted on the high-strength bolts 7.

[0018] In use, the installation between the H-beam 2 and the beam-column connecting Y-type plate 5 is completed by inserting the rear end of the H-beam 2 into the interior of the beam-column connecting Y-type plate 5, rotating each high-strength bolt 7 to pass through the corresponding through hole 6, and then tightening the nut 8, thereby further increasing the stability of the H-beam 2.

[0019] In some technical solutions, such as Figure 2 As shown, the thread helix angle of the threaded shaft 35 is less than the equivalent friction angle.

[0020] In use, the auxiliary support plate 31 is prevented from slipping off the threaded shaft 35 by using a threaded shaft 35 with a thread helix angle smaller than the equivalent friction angle.

[0021] In some technical solutions, such as Figure 2 As shown, the outer wall of the turntable 34 has several internal grooves 36 at equal intervals.

[0022] In use, the friction of rotating the turntable 34 is increased by multiple inner grooves 36, making it easier to rotate the turntable 34.

[0023] In some technical solutions, such as Figure 3-4 As shown, a matching washer 9 is fitted onto the high-strength bolt 7.

[0024] During use, the gasket 9 prevents the nut 8 from directly contacting the beam-column connecting Y-plate 5, thereby reducing friction between the nut 8 and the beam-column connecting Y-plate 5.

[0025] In some technical solutions, such as Figure 3 As shown, the rear side of the Y-shaped plate 5, which connects the beam and column, is welded to the H-shaped steel column 1.

[0026] When in use, it increases the connection strength of the Y-shaped plate 5 connecting the beam and column.

[0027] Working principle: During installation, two auxiliary support plates 31 are placed between two interrib stiffening plates 4. The turntable 34 is rotated so that the threaded shaft 35 passes through the corresponding threaded holes 33, thereby adjusting the distance between the two auxiliary support plates 31 until the two auxiliary support plates 31 and the two interrib stiffening plates 4 come into contact and abut each other, thus ensuring the flatness between the H-beam 2 and the interrib stiffening plates 4. The rear end of the H-beam 2 is inserted into the interior of the beam-column connecting Y-type plate 5. Each high-strength bolt 7 is rotated so that it passes through the corresponding through hole 6, and then the nut 8 is tightened to complete the installation between the H-beam 2 and the beam-column connecting Y-type plate 5. After the partial welding between the H-beam 2 and the interrib stiffening plates 4 is completed, the anti-deformation auxiliary component 3 is removed so that the remaining parts of the H-beam 2 and the interrib stiffening plates 4 can be welded.

[0028] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
