[0002] Steel structures are hailed by experts as the "green buildings" of the 21st century due to their light weight, high strength, excellent seismic performance, energy conservation and land saving, recyclability, short construction cycles, and minimal environmental pollution during construction and demolition. In developed countries, low-rise and high-rise steel-framed residential buildings are very common. In recent years, the application of steel structures in my country has been expanding due to their advantages such as earthquake resistance, wind resistance, durability, environmental protection, and rapid construction.

[0003] However, there are still a lot of problems in the installation process of various industrial and civil steel structures, especially large-span steel beams.

Therefore, support operations are often required during construction. At the construction site, the simpler support is to use wooden piles or ordinary steel pipes on site, but wooden piles and steel pipes are unstable and unsafe, or to use steel beams with the right size, which will cause a lot of steel loss.

Therefore, the above terms cannot be understood as limiting the present invention.

[0022] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0023] like Figure 1-3 As shown, the support device of a large-span steel beam of the present invention includes a support bottom plate 1, a fixed support column 2, a lifting mechanism 3, a support top plate 4, and a support side plate 5;

[0024] The supporting bottom plate 1 and the supporting top plate 4 are respectively vertically arranged at the bottom and top of the fixed support column 2. A lifting mechanism 3 that can be adjusted up and down is provided between the fixed support column 2 and the supporting top plate 4. Two supporting side plates 5 parallel to each other are provided on the top of the supporting top plate 4. The large-span steel beam is fixed between the supporting side plates 5 on both sides.

[0025] In the above technical solution, a large-span steel beam is placed between the supporting side plates 5, and then the beam can be clamped by multiple fastening bolts 6 to ensure the overall stability of the equipment. By setting a lifting mechanism 3, the height of the supporting top plate 4 is adjusted to adapt to large-span steel beams of different heights.

[0026] In another technical solution, fastening bolts 6 are vertically arranged on the supporting side panels 5. The fastening bolts 6 on the two supporting side panels are pressed against the large-span steel beam to fix and lock the large-span steel beam. By screwing in or out the fastening bolts 6, the steel beam can be locked and released in the opposite direction.

[0027] In another technical solution, fixed cross bars 7 are provided on both sides of the supporting base plate 1.

[0028] That is, when the bottom of the beam is not a beam, but a plane, the ground or a platform, the clamping plate 9 can be rotated upward, and the support base 1 can be directly supported on the plane, so as to facilitate the support of the entire equipment. The corresponding beam is under the beam, and the clamping plate 9 can be driven by the telescopic structure 8 to clamp the beam to ensure the stability of the equipment.

First limiting grooves 15 are provided on both sides of the fixed support column 2. The lifting mechanism 3 can be slidably set in the first limiting groove 15 through a first limiting slider 16. The first bevel gear transmission group 12 drives the first adjusting screw 13 to rotate, thereby driving the lifting structure 3 to be lifted and lowered, thereby adapting to large-span steel beams of different heights.

[0030] In another technical solution, the first bevel gear transmission group 12 is connected to a first rotating handle 14 extending to the outside to facilitate manual operation by staff.

[0031] In another technical solution, a second adjustment slot 17 is provided in the middle of the fixed cross bar 7, and a second bevel gear transmission group 18 is rotatably connected in the second adjustment slot 17. The second bevel gear transmission group 18 includes three bevel gears meshing with each other, and the gear hole of the middle bevel gear is connected to the second rotating handle 19, and the gear holes of the bevel gears on both sides are respectively connected to the second adjusting screws 20 on both sides, that is, the first rotating handle 14 cooperates with the second bevel gear transmission group 18 to drive the second adjusting screws 20 on both sides to rotate, thereby driving the telescopic structure 8 to perform telescopic adjustment, so that the steel beam at the bottom can be clamped.

[0032] In another technical solution, a second limiting groove 21 is provided in the fixed cross bar 7, and second limiting sliders 22 are provided on both sides of the rear end of the telescopic structure 8, which can be slidably arranged in the second limiting groove 21 to facilitate the telescopic structure to slide inside the fixed cross bar.

They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented.
