Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically to a movable prefabricated support beam for steel structures. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are primarily composed of steel beams, columns, trusses, and other components made of shaped steel and steel plates, and are treated with rust removal and prevention processes such as silanization, pure manganese phosphating, washing and drying, and galvanizing. The components are typically connected by welds, bolts, or rivets. Due to their light weight and ease of construction, steel structures are widely used in large factories, stadiums, and high-rise buildings.

[0003] A search revealed a movable prefabricated support beam for a steel structure, as disclosed in patent publication number CN114278008A. The structure includes a base, a square beam, a square beam base, a reinforcing block, a shock absorber platform, a platform reinforcing block, a shock absorber pressure plate, a shock absorber, a connecting beam, a connecting beam base, a crossbeam, and a support seat. The shock absorber includes a shock absorber base, a shock absorber top plate, a damper, base screw holes, and top plate screw holes. The support seat includes a support base, a support arm, a square steel support plate, base fixing screw holes, and support plate screw holes. The bottom end of the square beam is welded to the center of the top surface of the square beam base. The square beam base is installed in the center of the top surface of the base. This movable prefabricated support beam for a steel structure effectively reduces vibration in the steel structure, making it less prone to deformation and increasing its service life.

[0004] While the aforementioned support beams can dampen the steel structure and increase its service life, they are quite large and difficult to move and transport, which leads to a decrease in overall work efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a movable prefabricated support beam for steel structures to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a movable prefabricated support beam of steel structure, including a movable component, wherein an adjustment component is snapped onto the connecting end of the movable component, and a connecting frame is fixed to the top outer surface of both adjusting ends of the adjustment component by bolts, and a top beam is installed on the top outer surface of both connecting frames by bolts. The movable component is used for overall movement or for supporting the whole in contact with the ground, and the adjustment component is used for adjusting the height of the top beam.

[0007] Furthermore, the moving component includes a base cover, a C-shaped card plate is installed in the middle of the top outer surface of the base cover, and two symmetrically distributed L-shaped plates are installed on both sides of the C-shaped card plate. The top outer surface of the L-shaped plates has a circular opening, and a pin is slidably connected inside the circular opening.

[0008] Furthermore, four rectangularly arranged cylinders are mounted on the top outer surface of the bottom cover, and the piston rods of the four cylinders pass through the bottom cover and are mounted on the same mounting bracket. Four rectangularly arranged support rollers are mounted on the bottom outer surface of the mounting bracket.

[0009] Furthermore, the adjustment component includes a rectangular plate, which is snapped into the interior of a C-shaped plate. The top outer surface of the rectangular plate has four rectangularly distributed slots that engage with pins. A fixing shell is installed on the top outer surface of the rectangular plate, and a partition plate is installed at the bottom layer inside the fixing shell.

[0010] Furthermore, the top surface of the partition plate has an opening, and a fixed shaft is rotatably connected inside the opening. The top and bottom ends of the fixed shaft are connected to the fixed shell and the rectangular plate respectively through bearings. A first helical gear is sleeved on the bottom of the outer surface of the fixed shaft, and the upper surface of the fixed shaft is provided with threads. The fixed shaft is connected to an internal threaded block through the threads.

[0011] Furthermore, a mounting port is provided on the bottom of one side of the fixed housing, and a connecting shaft is connected to the inside of the mounting port via a bearing. One end of the connecting shaft extends into the inside of the fixed housing and a second helical gear is installed thereon. The second helical gear meshes with the first helical gear for transmission. A socket is installed on the other end of the connecting shaft, and a handle is inserted into the inside of the socket. Sliding openings are provided on both sides of the fixed housing, and an adjusting block is slidably connected inside the sliding opening. The adjusting block is fixedly connected to the built-in threaded block.

[0012] Furthermore, the two adjusting blocks are mounted on the same connecting plate on one side, and one side of the connecting plate has a threaded opening. A threaded rod is screwed into the inside of the threaded opening. The fixed shell has equidistantly distributed positioning grooves on the side of the fixed shell near the connecting plate. The positioning grooves and one end of the threaded rod form an insertion fit.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] A movable prefabricated support beam with a steel structure is provided, which is equipped with a moving component. When the moving component needs to be moved, multiple support rollers can be extended, thereby driving the whole structure to move, saving the operator's physical strength. When supporting, the multiple support rollers can be retracted into the bottom cover, allowing the bottom cover to contact the ground for support, thus improving work efficiency.

[0015] Meanwhile, the top beam is fixed to the connecting frame with bolts. Different types of top beams can be replaced as needed. Turning the handle can drive the top beam to adjust its height and make contact with the steel structure for support. It can flexibly adapt to the support work of steel structures of different heights. The adjustment components, top beam, two connecting frames and handle can all be disassembled for easy loading onto the truck. Attached Figure Description

Four rectangularly arranged support rollers 17 are mounted on the bottom outer surface of the mounting bracket 16.

[0030] It should be noted that the four support rollers 17 can extend out of the interior of the base cover 11 under the operation of the four cylinders 15, thereby enabling them to move.

[0031] The adjustment component 2 includes a rectangular plate 21, which is snapped into the interior of the C-shaped plate 12. The top surface of the rectangular plate 21 has four rectangularly distributed slots, which are engaged with the pins 14. A fixing shell 22 is installed on the top surface of the rectangular plate 21, and a partition plate 23 is installed at the bottom of the interior of the fixing shell 22.

[0032] It should be noted that the rectangular plate 21 and the top surface of the base cover 11 can form a sliding fit, and the pin 14 can contact the top of the base cover 11.

[0033] The top surface of the partition plate 23 has an opening, and the inside of the opening is rotatably connected to a fixed shaft 24.

[0039] Working principle: When the four cylinders 15 of the moving component 1 are in operation, multiple support rollers 17 can extend from the bottom cover 11 when movement is required, allowing the whole assembly to move. When the assembly is in the appropriate position, the four cylinders 15 reset, and the multiple support rollers 17 can retract into the bottom cover 11, allowing the bottom cover 11 to contact the ground for support. Then, the handle 210 is turned to make the second helical gear 28 mesh with the first helical gear 25 for transmission. Then, the fixed shaft 24 rotates, thereby driving the built-in threaded block 26 to move the two adjusting blocks 27 upward, thus allowing the top beam 4 to contact the steel structure for support.
