Description

Technical Field

[0001] This utility model is a steel structure connection device, belonging to the field of steel structure technology. Background Technology

[0002] I-beams, as a commonly used core component in steel structure engineering, are widely used in the construction of building frames, bridges, factories, and other structures due to their excellent mechanical properties and load-bearing capacity. In steel structure lap splicing construction, the connection between vertical and horizontal I-beams is a critical process, as its stability directly determines the safety performance of the overall structure. The current mainstream connection method is to achieve fixation using fasteners consisting of multiple sets of screws and nuts. Specifically, a connecting plate needs to be pre-welded to the end of the horizontal I-beam, with holes for the screws cut into the connecting plate. During connection, the connecting plate of the horizontal I-beam must first be aligned with the pre-set connecting surface of the vertical I-beam. Then, the screws are sequentially passed through the holes in the connecting plate and the corresponding holes in the vertical I-beam. Finally, the nut is tightened on the other end of the screw, and the locking force of the fasteners achieves a secure connection between the two.

[0003] Due to the high load-bearing requirements of I-beams, a single lap joint typically requires multiple sets of fasteners, and these sets must be evenly distributed to ensure balanced stress. This necessitates that operators meticulously align each screw with its corresponding nut during assembly—after the screw passes through the hole, the operator must hold the nut and align it with the threaded end of the screw to secure it. In actual construction, the placement of multiple sets of fasteners necessitates repeated alignment operations, with each alignment requiring meticulous adjustments, which is time-consuming. This frequent alignment process significantly slows down the connection progress of steel structures, especially in large-scale steel structure projects, where the accumulated time consumption is considerable, impacting construction efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a steel structure connection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel structure connection device, comprising: The vertical I-beam has two rows of first circular holes on each of its two parallel sides; A transverse I-beam has a connecting plate welded to its end. One side of the connecting plate has two rows of second circular holes, which are aligned with the first circular holes. Two sets of U-shaped plates are provided, and the two sets of U-shaped plates are symmetrically arranged inside the vertical I-beam. Screws are inserted into the channels formed by the first and second round holes, and one end of the screws is threadedly connected to the U-shaped plate.

[0006] Furthermore, multiple evenly arranged nuts are installed on the two parallel inner walls of the U-shaped plate. A third circular hole is provided in the area of ​​the U-shaped plate covered by the nuts, which is concentric with the nuts. One end of the screw passes through the third circular hole and is threadedly connected to the nut. There is a gap between the third circular hole and the first circular hole.

[0007] Furthermore, two symmetrically arranged plug sleeves are installed on the inner wall of the unprocessed third circular hole of the U-shaped plate. The plug sleeves are arranged vertically, and a plug rod is inserted into the plug sleeve. A connecting part is installed at the upper end of the plug rod, and a vertical plate is installed at the end of the connecting part away from the plug rod. The vertical plate is in contact with the side of the screw that is away from the nut.

[0008] Furthermore, the cross-section of the plug sleeve is U-shaped, and the length of the plug sleeve is less than the length of the plug rod.

[0009] Furthermore, the plug rod and the connecting part are integrally formed, and the connecting part and the vertical plate are integrally formed.

[0010] Furthermore, the connecting part has an "L" shaped structure, and a horizontal elongated oval opening is provided on one side of the connecting part.

[0011] Furthermore, one side of the U-shaped plate has a vertical elongated oval opening, which is located between two plug-in sleeves.

[0012] Furthermore, two sets of reinforcing ribs are welded to one end of the transverse I-beam near the connecting plate, and the reinforcing ribs are welded and fixed to the connecting plate.

[0013] The beneficial effects of this utility model are: Multiple evenly distributed nuts are pre-installed on the inner wall of the U-shaped plate, and the nuts are concentrically arranged with the third circular hole of the U-shaped plate, forming a nut pre-positioning structure. During connection, only a small amount of time is needed to align and tighten the initial few screws with the corresponding nuts on the U-shaped plate. Then, the relative positions of the U-shaped plate with the vertical and horizontal I-beams remain unchanged. Subsequent screws only need to pass through the channel formed by the first, second, and third circular holes and be threaded into the corresponding nuts. There is no need to align the screws and nuts one by one, which solves the problem of repeated alignment in traditional connections, reduces operation steps, and improves the construction efficiency of steel structure lap joints. It is especially suitable for batch connection operations in large-scale projects. Attached Figure Description

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a steel structure connection device, including a vertical I-beam 1, with two rows of first circular holes 11 on each of the two parallel sides of the vertical I-beam 1, and a connecting plate 22 welded to the end of a horizontal I-beam 2. The connecting plate 22 has two rows of second circular holes 23 on one side, so that the second circular holes 23 are aligned with the first circular holes 11 to facilitate the insertion of screws 4. Two sets of reinforcing ribs 21 are welded to the end of the horizontal I-beam 2 near the connecting plate 22, so that the reinforcing ribs 21 are welded and fixed to the connecting plate 22, thereby improving the mechanical strength of the connection between the connecting plate 22 and the horizontal I-beam 2.

[0017] See Figures 1-3Two sets of U-shaped plates 3 are symmetrically arranged inside the vertical I-beam 1. Screws 4 are inserted into the channels formed by the first circular hole 11 and the second circular hole 23. Multiple evenly distributed nuts 31 are installed on the two parallel inner walls of the U-shaped plates 3. The area of ​​the U-shaped plates 3 covered by the nuts 31 has a third circular hole 32 arranged concentrically with the nuts 31. One end of the screw 4 passes through the third circular hole 32 and is threadedly connected to the nut 31. Multiple evenly distributed nuts 31 are pre-fixed on the inner wall of the U-shaped plates 3, and each nut 31 is concentric with the third circular hole 32 on the U-shaped plates 3, forming a preset positioning structure. During the connection operation, only a few screws 4 need to be aligned with the corresponding nuts 31 on the U-shaped plates 3 and tightened to quickly lock the relative positions of the U-shaped plates 3, the vertical I-beam 1, and the horizontal I-beam 2. The remaining screws 4 do not need to be individually adjusted and aligned with the corresponding nuts 31. They can be directly threaded through the channel formed by the first round hole 11 of the vertical I-beam 1, the second round hole 23 of the connecting plate 22, and the third round hole 32 of the U-shaped plate 3 to be threaded with the corresponding pre-installed nuts 31. This eliminates the tedious steps of repeated alignment in traditional connections, simplifies the operation process, and improves the efficiency of steel structure splicing. It is especially suitable for batch connection scenarios in large-scale projects.

[0018] After the U-shaped plate 3 is assembled, there is a gap between the third circular hole 32 and the first circular hole 11. Therefore, if the screw 4 and nut 31 cannot be properly disassembled due to corrosion later, the screw 4 can be cut off using the gap between the first circular hole 11 and the third circular hole 32, allowing replacement of the fastener formed by the screw 4 and nut 31 without damaging other components. The two sets of U-shaped plates 3 are symmetrically arranged inside the vertical I-beam 1, forming multiple points of connection with the screw 4 through multiple sets of nuts 31, so that the load is evenly distributed to the U-shaped plate 3 and the vertical I-beam 1 as a whole, avoiding stress concentration on a single fastener. The rigid structure of the U-shaped plate 3 can further disperse stress, improve the load-bearing capacity of the connection parts, and meet the high-strength use requirements of I-beams in building frames, bridges, and other scenarios.

[0019] See Figures 1-4Two symmetrically arranged U-shaped insert sleeves 52 are installed on the inner wall of the unprocessed third circular hole 32 of the U-shaped plate 3. Insert rods 53 are inserted into the vertically arranged insert sleeves 52. The length of the insert sleeves 52 is less than the length of the insert rods 53. A connecting part 51 is installed at the upper end of the insert rods 53. A vertical plate 5 is installed at the end of the connecting part 51 away from the insert rods 53. The vertical plate 5 is in contact with the side of the screw 4 away from the nut 31. The insert rod 53 and the connecting part 51 are integrally formed. The L-shaped connecting part 51 and the vertical plate 5 are integrally formed. A horizontal elongated oval opening 54 is opened on one side of the connecting part 51, and a vertical elongated oval opening 33 is opened on one side of the U-shaped plate 3 between the two insert sleeves 52. This reduces material costs. The U-shaped plate 3 is connected to the insert rod 53 through the insert sleeves 52. After the vertical plate 5 is in contact with the side of the screw 4 away from the nut 31, the position of the screw 4 is restricted to prevent the screw 4 from loosening due to vibration.
