Description

Technical Field

[0001] This utility model relates to the field of H-beams, specifically an H-beam with a stable weldable structure. Background Technology

[0002] H-beams are a new type of economical building steel. 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. High-frequency welded H-beams, which rely on high-frequency current to locally melt and weld the metal, do not require welding wire or flux. They can be produced at high speed and continuously, with high output and easy mechanization and automation, making high-frequency welded H-beams increasingly widely used in practical applications.

[0003] According to Chinese Patent No. CN216842544U, a high-frequency welded H-beam with a stable welding structure is disclosed. This utility model uses guide rods and guide holes to connect vertically connected first H-beams together, thus ensuring the stability of the first H-beam connection during welding. This design can effectively improve the stability and convenience of the vertical connection of the first H-beams during use, and is worthy of widespread promotion and use.

[0004] Regarding the aforementioned patent content, existing high-frequency welded H-beams have guide rods installed on one side and guide holes opened on the other side. During splicing, the guide rod is inserted into the guide hole of another H-beam, thus completing the splicing and facilitating subsequent stable welding of the H-beams. However, the splicing components (such as the guide rod structure used for positioning) are easily damaged by bumps during transportation or handling, affecting subsequent use. Moreover, as a key component of splicing, if the guide rod is exposed for a long time, it is prone to collisions and friction with other objects during transportation, handling, or storage, leading to wear or even breakage of the positioning rod. This directly affects the compatibility with the slot during subsequent splicing, reducing splicing accuracy and stability. At the same time, the exposed guide rod will form a protruding structure, which may cause accidental injuries such as bumps and scratches to operators during construction or handling, thereby affecting construction safety and convenience. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide an H-beam with a stable welded structure to solve the technical problem that the guide rod is prone to collision with other external objects during handling or transportation.

[0006] To achieve the above object, the utility model provides the following technical solution: an H-shaped steel with a stable welding structure, including an H-shaped steel main body. On both the upper and lower sides of one side of the H-shaped steel main body, receiving grooves are provided. On both the upper and lower sides of the other side of the H-shaped steel main body, slots are provided. Inside the two receiving grooves, inserting plates are arranged. Inside the H-shaped steel main body, a sliding groove is provided, and inside the sliding groove, a sliding seat is arranged. And on the inner wall of the sliding groove, two screw holes are provided. On both the top and bottom of the sliding seat, vertical plates are fixed, and the vertical plates are fixedly connected with the inserting plates.

[0007] By adopting the above technical solution, when it is necessary to splice the H-shaped steel main body, the staff first screws out the locking bolt to release the limit on the sliding seat, and then pushes the vertical plate, so that the vertical plate moves and带动 the inserting plate to move.

[0008] Further, a locking bolt is threadedly connected to the sliding seat and extends into one of the screw holes.

[0009] By adopting the above technical solution, after the locking bolt is screwed into the corresponding screw hole, the sliding seat can be locked and limited to prevent the sliding seat from moving randomly.

[0010] Further, a self-locking nut is threadedly connected to the end of the locking bolt, and the self-locking nut is in contact with the inner wall of the H-shaped steel main body.

[0011] By adopting the above technical solution, after the self-locking nut is threadedly connected to the locking bolt, the stability of the locking bolt can be improved, and the probability of the locking bolt loosening can be reduced.

[0012] Further, a plurality of reinforcing ribs are welded equidistantly inside the H-shaped steel main body, and the reinforcing ribs are made of low-alloy high-strength steel (such as Q390 or Q420) materials.

[0013] By adopting the above technical solution, the strength of the H-shaped steel main body can be improved, and its bearing capacity can be increased.

[0014] Further, the inserting plate is adapted to both the receiving groove and the slot.

[0015] By adopting the above technical solution, the inserting plate can also be inserted into the slot, so as to position the H-shaped steel main body and facilitate the splicing of the H-shaped steel main body.

[0016] Further, the vertical plate is slidably connected to the sliding groove through the sliding seat.

[0017] By adopting the above technical solution, when the vertical plate moves, it can带动 the sliding seat to slide inside the sliding groove, thereby improving the stability of the vertical plate when it moves.

[0018] Further, the inserting plate is slidably connected to the receiving groove, and the inserting plate is in a "convex" shape.

[0019] By adopting the above technical solution, the insert plate can slide inside the storage slot.

[0020] Furthermore, the insert plate, vertical plate, and slide are all made of Q235 steel.

[0021] By adopting the above technical solution and using Q235 steel, the strength of the insert plate, vertical plate, and slide can be improved.

[0022] Furthermore, a positioning block is fixed inside the upper part of the H-beam body, and the positioning block is made of Q235 steel.

[0023] By adopting the above technical solution, the positioning block can limit the vertical plate and prevent it from moving excessively.

[0024] In summary, the present invention has the following main advantages: 1. This utility model, by providing an insert plate, a storage groove, a vertical plate, a sliding block, a sliding groove, locking bolts, and screw holes, allows the insert plate to be stored inside the storage groove when H-beams do not need to be spliced. This prevents any protruding parts from the edges of the H-beams, thus avoiding damage to the insert plate from external objects and improving the protection of the insert plate. It also prevents the insert plate from colliding with operators during transportation, making it convenient for operators to transport or handle H-beams. When splicing H-beams is required, the operator first unscrews the locking bolts to release the restriction on the sliding block, then pushes the vertical plate, causing it to move and move the insert plate. After the insert plate is removed from the storage groove, the H-beams can be spliced ​​using the insert plate. 2. This utility model is equipped with a positioning block and a self-locking nut. When the vertical plate moves and contacts the positioning block, the locking bolt on the slide aligns with another screw hole. At this time, the locking bolt can be screwed into the corresponding screw hole, and then the self-locking nut is screwed to one end of the locking bolt. The self-locking nut is in contact with the inner wall of the H-beam. This can achieve the purpose of locking and limiting the slide, preventing the slide, vertical plate and insert plate from moving at will, so that the insert plate can be stably inserted into the corresponding slot.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] Example 1: An H-beam with a stable weldable structure, such as Figures 1-7 As shown, the structure includes an H-beam body 1. Storage slots 5 are provided on the upper and lower sides of one side of the H-beam body 1, and slots 3 are provided on the upper and lower sides of the other side. Insert plates 6 are installed inside the two storage slots 5. A sliding groove 9 is provided inside the H-beam body 1, and a sliding seat 8 is installed inside the sliding groove 9. Two screw holes 10 are provided on the inner wall of the sliding groove 9. Vertical plates 7 are fixed to the top and bottom of the sliding seat 8, and the vertical plates 7 are fixedly connected to the insert plates 6. When the H-beam body 1 needs to be assembled, the worker first unscrews the locking bolts 4 to release the restriction on the sliding seat 8, and then pushes the vertical plates 7, causing them to move and move the insert plates 6. The insert plates 6 are compatible with both the storage slots 5 and the slots 3, so that the insert plates 6 can also be inserted into the slots 3, thereby positioning the H-beam body 1 and facilitating its assembly.

[0030] See Figures 1-7The vertical plate 7 is slidably connected to the slide groove 9 via the slide block 8. When the vertical plate 7 moves, it can drive the slide block 8 to slide inside the slide groove 9, thereby improving the stability of the vertical plate 7 when moving. The insert plate 6 is slidably connected to the storage groove 5. The insert plate 6 is convex in shape so that the insert plate 6 can slide inside the storage groove 5. The insert plate 6, the vertical plate 7 and the slide block 8 are all made of Q235 steel. The use of Q235 steel can improve the strength of the insert plate 6, the vertical plate 7 and the slide block 8. A positioning block 12 is also fixed inside the upper part of the H-shaped steel body 1. The positioning block 12 is made of Q235 steel. The positioning block 12 can limit the vertical plate 7 and prevent the vertical plate 7 from moving excessively. When the vertical plate 7 moves and contacts the positioning block 12, the locking bolt 4 on the slide block 8 is aligned with another screw hole 10. At this time, the locking bolt 4 can be screwed into the corresponding screw hole 10, thereby locking and limiting the slide block 8.

[0031] Example 2: Based on the above embodiment 1, in order to improve the stability of the slide 8, it is necessary to lock and limit the slide 8, so the following structure will be set.

[0032] Specifically, the slide block 8 is threaded with a locking bolt 4 extending into a screw hole 10. When the locking bolt 4 is screwed into the corresponding screw hole 10, the slide block 8 can be locked and limited to prevent it from moving at will. The end of the locking bolt 4 is threaded with a self-locking nut 11, and the self-locking nut 11 fits against the inner wall of the H-beam body 1. The self-locking nut 11 threaded onto the locking bolt 4 can improve the stability of the locking bolt 4 and reduce the probability of the locking bolt 4 loosening.

[0033] Example 3: Based on the above embodiment 1, the following structure will be set to improve the strength of the H-beam body 1.

[0034] See Figures 1-5 The H-beam body 1 has multiple reinforcing ribs 2 welded at equal intervals inside. The reinforcing ribs 2 are made of low alloy high strength steel (such as Q390 or Q420 material) to improve the strength of the H-beam body 1 and increase its load-bearing capacity.

[0035] The working principle of this utility model is as follows: First, when there is no need to splice the high-frequency welded H-beam (such as to handle or transport the high-frequency welded H-beam), the insert plate 6 can be hidden in the storage groove 5, so that there will be no protruding parts on the edge of the H-beam, and the insert plate 6 will not be damaged by bumps, thus facilitating the handling or transportation of the high-frequency welded H-beam. When splicing high-frequency welded H-beams, the workers first unscrew the locking bolt 4 to release the limit on the slide block 8, then push the vertical plate 7, causing it to move and move the insert plate 6. When the vertical plate 7 moves and contacts the positioning block 12, the locking bolt 4 on the slide block 8 aligns with another screw hole 10. At this time, the locking bolt 4 can be screwed into the corresponding screw hole 10. Then, the self-locking nut 11 is screwed to one end of the locking bolt 4, and the self-locking nut 11 is in contact with the inner wall of the H-beam. This achieves the purpose of locking and limiting the slide block 8, preventing the slide block 8, the vertical plate 7, and the insert plate 6 from moving arbitrarily. Then, the workers insert the insert plate 6 into the slot 3 of another H-beam to complete the splicing and positioning. Then, the spliced ​​H-beams can be stably welded.
