[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a prefabricated steel structure beam, including an H-shaped beam 1 and a clamping box 2. A handle 3 is rotatably connected to the top of the clamping box 2, and a central gear 4 is fixedly connected to the bottom of the handle 3. A fixed shaft 5 is fixedly connected to the bottom of the central gear 4, and a rotating seat 6 is sleeved on the bottom of the fixed shaft 5. The bottom of the rotating seat 6 is fixedly connected to the top of the clamping box 2. The rotation of the central gear 4 drives the second transverse toothed plate 9, which is meshed and rotatably connected to the outside, to rotate. At the same time, a second clamping plate 10, which is welded and fixedly connected to the outside of the second transverse toothed plate 9, slides towards the inner wall of the clamping box 2. A first transverse toothed plate 7 is meshed and rotatably connected to the outside of the central gear 4. A first clamping plate 8 is welded and fixed to the left side of the first transverse toothed plate 7. The outside of the second clamping plate 10 abuts against the second reinforcing beam 14 and slides towards the inside of the clamping box 2. A second extension plate 15 is welded to the left front end of the second reinforcing beam 14. The outside of the second extension plate 15 slides into the groove of the first reinforcing beam 12, realizing the connection between the two sets of beams.

[0023] Specifically, an extension rod 23 is fixedly connected to the right side of the H-beam 1, and a first reinforcing beam 12 is welded to the top of the extension rod 23. A first extension plate 13 is fixedly connected to the right side of the first reinforcing beam 12. A groove is provided on the left side of the second reinforcing beam 14. The first extension plate 13 is slidably disposed inside the groove of the second reinforcing beam 14, which can fit and fix the two sets of beams together.

[0024] Furthermore, a threaded groove is provided inside the right side of the H-beam 1, and a bolt 11 is spirally connected to the outside of the reinforcing plate 22. The bolt 11 penetrates the interior of the reinforcing plate 22 and is spirally connected to the threaded groove of the H-beam 1.

[0025] Furthermore, there are two sets of reinforcing plates 22, and the interior of the two sets of reinforcing plates 22 is welded to the first reinforcing beam 12. The beams connected by this method have a longer service life.

[0026] It is worth noting that the outer side of the first reinforcing beam 12 is fixedly connected to the first extension block 16, and the outer side of the second reinforcing beam 14 is fixedly connected to the second extension block 17. The connecting rod 18 passes through the interior of the second extension block 17. The connecting rod 18 slides left and right inside the first extension block 16 and the second extension block 17 to support the positioning of the first reinforcing beam 12 and the second reinforcing beam 14.

[0027] It is worth noting that a rotating plate 19 is rotatably connected to the top of the clamping box 2. A round hole is opened inside the left side of the rotating plate 19. A protrusion 20 is fixedly connected inside the round hole of the rotating plate 19. A spring 21 is sleeved on the outside of the protrusion 20.

[0028] It is worth mentioning that the top of the clamping box 2 is provided with a round hole groove. The protrusion 20 at the top of the rotating plate 19 rotates inside the round hole groove of the clamping box 2. By moving it outward, the rotating plate 19 can be pulled out from one side of the clamping box 2, which is convenient for subsequent processing.

[0029] It is worth emphasizing that the first reinforcing beam 12 and the second reinforcing beam 14 are located inside the clamping box 2, with the right side of the first reinforcing beam 12 located on the left side of the second reinforcing beam 14. Adjusting the position of the second reinforcing beam 14 facilitates the subsequent welding of the two sets of beams.

[0030] The H-beam 1 is existing technology and will not be described further; this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described further; the "front, rear, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0031] Working principle:

[0032] First, the workers fix the reinforcing plate 22 to the H-beam 1 using bolts 11. The first reinforcing beam 12 is then lifted and placed at the top of the extension rod 23. The reinforcing plate 22 is welded to the first reinforcing beam 12. The second reinforcing beam 14 is fixed in the same way. The clamping box 2 is then fitted between the two. The handle 3 is turned, causing the central gear 4 at the bottom to rotate. The central gear 4 causes the first clamping plate 8 welded to the outer side of the first transverse toothed plate 7 to move against the first extension plate 13 at the front end of the first reinforcing beam 12. Similarly, the second transverse toothed plate 9 causes the second clamping plate 10 to move against the second reinforcing beam 12. 4. The second extension plate 15 at the front end is displaced, and the first reinforcing beam 12 is inserted into the groove inside the second reinforcing beam 14 to fix the two sets of beams. Then, the connecting rod 18 is inserted into the inside of the first extension block 16 on the outside of the first reinforcing beam 12 and the inside of the second reinforcing beam 14 for support and fixation. Then, the rotating plate 19 is rotated out from the rear side of the clamping box 2 and moved outward. The protrusion 20 at the top of the rotating plate 19 compresses the spring 21 and slides out from the round groove at the top of the clamping box 2. The rotating plate 19 is pulled out. Then, the clamping box 2 is pulled out from the outside of the two sets of beams and the two sets of beams are welded together.
