[0032] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0033] See Figure 1 - Figure 8 The utility model provides a steel structure reinforcement device, including a main support beam 100, an auxiliary beam 200 and a fixing plate 300; two slide grooves 110 are opened in the main support beam 100; the auxiliary beams 200 are arranged in pairs, and one end of each pair of auxiliary beams 200 extends into any slide groove 110 and is slidably connected to the slide groove 110; the fixing plate 300 is detachably connected to the end of each pair of auxiliary beams 200 away from the main support beam 100, and the fixing plate 300 is used to fix the steel structure beam.

[0034] During use, each pair of auxiliary beams 200 is first extended or retracted to the desired length based on the size of the steel beam. The final reinforcement is then achieved by securing the fixing plate 300 to the steel beam. The sliding connection between the auxiliary beams 200 and the chute 110 facilitates extension and retraction. Furthermore, the dual chute 110 and paired auxiliary beams 200 significantly enhance the load-bearing capacity and stability of the steel structure reinforcement device.

[0035] Furthermore, in one embodiment of the present invention, guide grooves 120 are provided on the two opposite inner walls of the slide groove 110, and a limiting protrusion 400 is provided on the auxiliary beam 200. The limiting protrusion 400 is used to adapt to the guide groove 120, so that the auxiliary beam 200 can be accurately guided and its stability can be improved.

[0036] Furthermore, in one embodiment of the present invention, the width of the slide groove 110 is at most four-fifths of the width of the main support beam 100, so as to increase the contact area and thereby improve the overall rigidity and stability.

[0037] Furthermore, in one embodiment of the present invention, a plurality of first threaded holes 130 are provided in the center of the top of the main support beam 100. First bolts 500 are passed through the first threaded holes 130. The first bolts 500 are used to connect and fasten the auxiliary beam 200. It should be noted that the first threaded holes 130 are also provided on the auxiliary beam 200 to facilitate the use of the first bolts 500.

[0038] Furthermore, in one embodiment of the present invention, a plurality of first threaded holes 130 are arranged in groups, with four holes in each group, and different groups are evenly distributed along the axial direction of the main support beam 100 , which can enhance the fastening of the auxiliary beam 200 .

[0039] Furthermore, in one embodiment of the present invention, the length of the auxiliary beam 200 is half of the main support beam 100 , which can effectively improve the support performance of the auxiliary beam 200 .

[0040] Furthermore, in one embodiment of the present invention, the fixing plate 300 and the main support beam 100 are tilted, and the tilt angle is 45°, which can effectively improve the rigidity and strength of the steel structure beam.

[0041] Furthermore, in one embodiment of the present invention, the fixing plate 300 includes a main plate 310 and two connecting plates 320. The two connecting plates 320 are both disposed on the same side of the main plate 310 and are fixedly connected to the main plate 310. One end of each connecting plate 320 extends into each pair of auxiliary beams 200 and is detachably connected to the auxiliary beams 200. Specifically, this is achieved by first bolts 500 and first threaded holes 130.

[0042] Furthermore, in one embodiment of the present invention, at least four fastening bolts 600 are passed through the fixing plate 300 , and the fastening bolts 600 are used to fix the steel structure beams.

[0043] Furthermore, in one embodiment of the present invention, the guide grooves 120 are arranged in groups, and at least two groups are provided in any slide groove 110 , so that the auxiliary beam 200 can be used more smoothly and stably.

[0044] When the above-mentioned steel structure reinforcement device is used, the length of the auxiliary beam 200 extending from the main support beam 100 is first adjusted according to the size of the steel structure crossbeam, and the auxiliary beam 200 is fastened to the main support beam 100 and the fixing plate 300 is fastened to the auxiliary beam 200 by the first bolt 500. Then, the fixing plate 300 is fixed to the steel structure crossbeam by the fastening bolt 600. Due to the structural design of the double chute 110 and the double auxiliary beam 200 in the reinforcement device, the auxiliary beam 200 is no longer thin when actually subjected to force, and has better load-bearing capacity and stability. Furthermore, the fixing plate 300 also provides sufficient support for the auxiliary beam 200, enhancing the overall rigidity and strength. In addition, since the auxiliary beam 200 and the chute 110 are connected in a sliding manner, telescopic adjustment is also more convenient.

[0045] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
