Detailed Implementation

[0019] The invention will now be described in detail with reference to the accompanying drawings, by way of example. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments.

[0020] Example 1 like Figure 1 As shown, the present invention provides a steel beam connection structure, including square steel 1, H-beam 2, connecting component one and connecting component two. Connecting component one includes a rectangular outer tube 3, with square steel 1 inserted into both ends of the rectangular outer tube 3. Connecting component two includes two wing plates 4 arranged side by side, with bolt holes on the wing plates 4. One end of the wing plate 4 is connected to the rectangular outer tube 3. Both wing plates 4 are provided with locking mechanisms, which cooperate to lock the ends of the H-beam 2. Connecting component two is located on at least one outer plane of connecting component one, which facilitates selection and setting according to connection requirements.

[0021] Furthermore, in this embodiment, the locking mechanism includes a snap-fit ​​plate 5 with elastic deformation function. One end of the snap-fit ​​plate 5 is connected to the wing plate 4, and the other end extends obliquely towards the rectangular outer sleeve 3 and has a gap with the rectangular outer sleeve 3. The snap-fit ​​plate 5 has bolt holes, which are concentrically arranged with the bolt holes on the wing plate 4, and the same locking bolt 6 is connected in the two bolt holes. The bottom of the locking bolt 6 is provided with a limiting platform 7, and a spring 8 is sleeved on the locking bolt between the wing plate 4 and the snap-fit ​​plate 5.

[0022] Furthermore, in this embodiment, a step 10 is provided at the end of the H-beam 2, and the width of the step 10 matches the width of the gap, which helps to further improve the locking performance.

[0023] like Figure 2 As shown, further, in this embodiment, a partition 13 is provided in the middle of the inner side of the rectangular outer tube 3. A rectangular boss 14 is provided on the top and bottom surfaces of the partition 13. The end of the square steel 1 is inserted into the rectangular boss 14. In order to further improve the fastening performance, the width between the inner wall of the rectangular outer tube 3 and the outer wall of the rectangular boss 14 is consistent with the wall thickness of the square steel 1. The upper end and the lower end of the rectangular outer tube 3 are respectively connected to the two square steels 1 by bolts.

[0024] In the first embodiment, during assembly, the ends of the two square steel bars 1 are first inserted into the rectangular bosses 14 inside the rectangular outer tube 3, and then the two square steel bars 1 are fastened to the rectangular outer tube 3 with bolts. Next, one end of the wing plate 4 is welded to the wall of the rectangular outer tube 3, and the two upper and lower locking bolts 6 are loosened. Under the action of the limiting platform 7, the spring 8 is pressed. At this time, the H-beam 2 is inserted between the two wing plates 4, and the step 10 on the end of the wing plate 4 is located in the gap between the rectangular outer tube 3 and the snap-fit ​​plate 5. Finally, the locking bolts 6 are tightened. After the spring 8 returns to its original position, the snap-fit ​​plate 5 is pushed onto the H-beam 2, and the snap-fit ​​plate 5 is locked by abutting against the step 10.

[0025] Example 2 like Figure 3 As shown, it is the same as in Embodiment 1, except that: the H-beam 2 is provided with a slot 11, and the snap-fit ​​plate 5 is provided with a vertical snap block 12 at one end near the rectangular outer sleeve 3. The vertical snap block 12 cooperates with the slot 11 to achieve locking; the end of the H-beam 2 does not need to be provided with a step 10.

[0026] The locking method of Embodiment 2 is slightly different from that of Embodiment 1. The operation of inserting the H-beam 2 between the upper and lower wing plates 4 is the same as that of Embodiment 1. The difference is that the locking method of Embodiment 2 is to tighten the locking bolt 6. During the tightening process, the vertical locking block 12 on the locking plate 5 gradually enters the locking groove 11 on the H-beam 2 to achieve locking.

[0027] Example 3 like Figure 4 As shown, the method is the same as in Embodiment 1, except that the locking mechanism includes a groove 9 formed on the inner wall of the wing plate 4. When locking, the end of the H-beam 2 is slidably connected in the groove 9. The H-beam 2 is provided with bolt holes, and the H-beam 2 is connected to the wing plate 4 by locking bolts 6. There is no need to provide a step 10 on the end of the H-beam 2.

[0028] In embodiment three, during assembly, the upper and lower ends of the H-beam 2 are slidably connected between the two flanges 4 through the sliding grooves 9. After the connection is completed, the bolt holes on the flanges 4 are aligned with the bolt holes on the H-beam 2, and the locking bolts 6 are used to lock them.

[0029] Example 4 like Figures 5 to 7 As shown, it is the same as in Embodiment 3, except that: the connection between the connecting component 1 and the connecting component 2 is provided with an adjustment mechanism, the adjustment mechanism includes a toothed slide 15 opened on the side wall of the rectangular outer tube 3, and a wing plate 4 is slidably connected in the toothed slide 15.

[0030] The wing plate 4 includes a left wing plate 41 and a right wing plate 42. A strip-shaped hole 16 is provided on the side of the left wing plate 41 opposite to the right wing plate 42. A movable cavity 17 is provided in the strip-shaped hole 16. A strip-shaped block 18 is provided on one side of the right wing plate 42. The strip-shaped block 18 extends into the movable cavity 17. The thickness of the strip-shaped block 18 matches the opening size of the strip-shaped hole 16. Both the upper and lower ends of the strip-shaped block 18 are provided with stop blocks 19. The two stop blocks 19 are respectively engaged with the upper and lower ends of the strip-shaped hole 16.

[0031] The left wing plate 41 has a left slider 43 at its front end, and the right wing plate 42 has a right slider 44 at its front end. The left slider 43 and the right slider 44 are connected by a telescopic mechanism. The telescopic mechanism includes an inner tube 20 and an outer tube 21. The inner tube 20 is sleeved inside the outer tube 21, and the inner tube 20 and the outer tube 21 are connected by a spring 22.

[0032] The technical solution of Embodiment 4 enables the adjustment of connecting component 2 relative to connecting component 1 to accommodate H-beams 2 of different widths. During assembly, the left slider 43 is welded to the left wing plate 41, the right slider 44 to the right wing plate 42, the left slider 43 to the inner tube 20, and the right slider 44 to the outer tube 21, respectively. A telescopic structure is formed between the left slider 43 and the right slider 44, and between the left wing plate 41 and the right wing plate 42. The left slider 43 and the right slider 44 are placed in the toothed slide rail 15, and the wing plate 4 is adjusted up and down by pressing the left slider 43 and the right slider 44.

[0033] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and application concept of the present invention, should be covered within the scope of protection of the present invention.
