Description

Technical Field

[0001] This utility model relates to the field of building connection structure technology, specifically to a steel structure connection structure. Background Technology

[0002] Steel structures, primarily constructed from steel, are one of the main types of building structures. Steel is characterized by high strength, light weight, good overall rigidity, and strong deformation capacity, making it particularly suitable for constructing large-span, super-high, and super-heavy buildings. It also exhibits good homogeneity and isotropy, making it an ideal elastic material that best conforms to the basic assumptions of general engineering mechanics. Furthermore, steel possesses good plasticity and toughness, allowing for significant deformation and excellent resistance to dynamic loads. Construction periods are short, and its high degree of industrialization enables highly mechanized and specialized production. In steel structure buildings, steel connecting structures are often used to connect two perpendicular I-beams.

[0003] Currently, the connection and fixation between two perpendicular I-beams is mainly achieved using four L-shaped plates and multiple sets of bolt assemblies. Although the above connection structure can achieve the connection between two perpendicular I-beams, each L-shaped plate requires no less than four sets of bolt assemblies to connect it to the two perpendicular I-beams. The repeated tightening of the bolt assemblies makes the connection process between the two perpendicular I-beams quite cumbersome, which not only increases the labor intensity but also makes the connection and fixation efficiency between the two perpendicular I-beams relatively low. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to provide a steel structure connection structure that can effectively reduce the use of bolt components and has high connection and fixing efficiency, while realizing the convenient connection of two mutually perpendicular I-beams.

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes a steel structure connection structure, including an I-beam body one. A U-shaped connecting plate is fixed at the connection part on one side wall of the I-beam body one by two locking members. Two limiting stops are symmetrically fixed on the upper and lower sides of the U-shaped connecting plate. Two rotating sleeves are symmetrically fixed on the upper and lower sides of the U-shaped connecting plate. A threaded rod is connected to each rotating sleeve. A handwheel is fixed at the end of the threaded rod away from the U-shaped connecting plate. A linkage plate passes through the threaded rod. Two limiting inserts are symmetrically fixed on the linkage plate on both sides of the threaded rod. A sliding hole is opened at the part of the U-shaped connecting plate that cooperates with the limiting insert. An I-beam body two is arranged on one side of the I-beam body one. A limiting insert corresponding to the sliding hole is opened at the connection end of the I-beam body two.

[0008] Furthermore, the locking component consists of bolts, nuts, and washers, and the locking component penetrates through the U-shaped connecting plate and the I-beam body.

[0009] By adopting the above technical solution, the U-shaped connecting plate and the I-beam body can be reliably connected and fixed under the action of the locking member.

[0010] Furthermore, the limiting stop is welded to the U-shaped connecting plate, and the limiting stop has an L-shaped structure.

[0011] By adopting the above technical solution, the limiting stop can initially limit and block the second I-beam.

[0012] Furthermore, the rotating sleeve is welded to the U-shaped connecting plate, and the threaded rod is rotatably connected to the rotating sleeve.

[0013] By adopting the above technical solution, the swivel sleeve can ensure convenient rotation of the threaded rod relative to the U-shaped connecting plate.

[0014] Furthermore, the threaded rod is threadedly connected to the linkage plate, and the threaded rod is bolted to the handwheel.

[0015] By adopting the above technical solution, the threaded rod can be rotated under the action of the handwheel to facilitate the insertion of the limiting rod into the limiting hole.

[0016] Furthermore, the limiting rod is welded to the linkage plate, and the limiting rod is slidably connected to the sliding hole.

[0017] By adopting the above technical solution, the sliding of the limiting rod relative to the sliding hole can be ensured.

[0018] Furthermore, the size of the limiting plug rod matches the size of the limiting plug hole.

[0019] By adopting the above technical solution, the limiting rod and the limiting hole can cooperate to achieve secondary limiting of the I-beam body after insertion.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, this utility model has the following advantages:

[0022] To address the current method of connecting and fixing two perpendicular I-beams, which primarily relies on four L-shaped plates and multiple sets of bolts, this approach, while achieving the connection, is cumbersome due to the need for at least four sets of bolts for each L-shaped plate. This repeated tightening of bolts makes the connection process tedious, increasing labor intensity and reducing efficiency. This invention addresses the issue of pre-installed bolts... The U-shaped connecting plate is fixed to the first I-beam using two locking devices. Then, the second I-beam is inserted into the U-shaped connecting plate by sliding. By rotating the upper and lower handwheels respectively, the limiting rod is inserted into the corresponding limiting hole, thereby achieving quick positioning of the second I-beam after insertion. Since the connection between the first and second I-beams can be fixed by only four turning operations under the above connection method, and the use of bolt assemblies is reduced, the connection efficiency between the first and second I-beams can be improved, while reducing the manual labor intensity when connecting the first and second I-beams.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] like Figures 1-2 As shown, a steel structure connection structure in this embodiment includes an I-beam body 9. A U-shaped connecting plate 4 is fixed to the connection point on one side wall of the I-beam body 9 by two locking pieces 8. Two limiting flanges 5 are symmetrically fixed on the upper and lower sides of the U-shaped connecting plate 4, providing initial limiting and blocking for the I-beam body 7. Two rotating sleeves 10 are symmetrically fixed on the upper and lower sides of the U-shaped connecting plate 4. Each rotating sleeve 10 is connected to a threaded rod 12. A handwheel 1 is fixed to the end of the threaded rod 12 away from the U-shaped connecting plate 4. A linkage plate 2 runs through the threaded rod 12. Two limiting rods 3 are symmetrically fixed on both sides of the linkage plate 2. A sliding hole 11 is provided on the U-shaped connecting plate 4 at the part that mates with the limiting rod 3. An I-shaped beam 7 is arranged on one side of the I-shaped beam 9. The connecting end of the I-shaped beam 7 is provided with a limiting hole 6 corresponding to the sliding hole 11. After the threaded rod 12 is rotated under the action of the handwheel 1, the limiting rod 3 can be conveniently inserted into the limiting hole 6. The limiting rod 3 and the limiting hole 6 can achieve secondary limiting of the I-shaped beam 7 after insertion.

[0029] like Figures 1-2 As shown, in this embodiment, the locking member 8 is composed of bolts, nuts and washers. The locking member 8 passes through the U-shaped connecting plate 4 and the I-beam body 9. Under the action of the locking member 8, the U-shaped connecting plate 4 and the I-beam body 9 can be reliably connected and fixed.

[0030] like Figures 1-2 As shown, in this embodiment, the limiting stop 5 is welded to the U-shaped connecting plate 4. The limiting stop 5 has an L-shaped structure. The rotating sleeve 10 is welded to the U-shaped connecting plate 4. The threaded rod 12 is rotatably connected to the rotating sleeve 10. The rotating sleeve 10 can ensure that the threaded rod 12 can be easily rotated relative to the U-shaped connecting plate 4. The threaded rod 12 is threadedly connected to the linkage plate 2. The threaded rod 12 is bolted to the handwheel 1. The limiting insert 3 is welded to the linkage plate 2. The limiting insert 3 is slidably connected to the sliding hole 11. This can ensure that the limiting insert 3 can slide easily relative to the sliding hole 11. The size of the limiting insert 3 matches the size of the limiting insert hole 6.

[0031] The specific implementation process of this embodiment is as follows: In use, the U-shaped connecting plate 4 is first fixed to the I-beam body 9 by means of two locking parts 8. Then, the I-beam body 7 is inserted into the U-shaped connecting plate 4 by sliding. The limiting rod 3 is inserted into the corresponding limiting hole 6 by rotating the upper and lower handwheels 1 respectively. This achieves quick limiting of the I-beam body 7 after insertion. Since the connection between the I-beam body 9 and the I-beam body 7 can be fixed by only four turning operations under the above connection method, and the use of bolt assemblies is reduced, the connection efficiency between the I-beam body 9 and the I-beam body 7 can be improved under the above connection structure, while reducing the manual labor intensity when connecting the I-beam body 9 and the I-beam body 7.

[0032] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
