Description

Technical Field

[0001] This utility model relates to the field of overall lifting and renovation technology for steel structure roofs, and in particular to a steel column hoisting and installation device for overall lifting of steel structure roofs. Background Technology

[0002] A domestic integrated transportation hub project uses a steel structure roof with overall plan dimensions of 43 meters × 55.6 meters. The main steel structure building is approximately 9.2 meters high, with a total weight of about 650 tons. The frame columns and frame beams are rigidly connected. To meet the requirements of a smart hub, the roof needs to be raised by 1.2 meters. Several popular space frame installation methods in the domestic and international markets include high-altitude assembly, overall jacking, overall lifting, overall hoisting, and sliding construction. Through analysis and comparison, and considering factors such as the steel space frame structure, site environment, and construction requirements of the integrated transportation hub project, the overall jacking method was chosen for construction. This overall jacking involves expanding and assembling the structure using a cumulative jacking method on a ground-based formwork. After the jacking support columns have raised the steel structure roof, a 1.2-meter-high extension steel column 300 needs to be installed between the upper steel column 200 and the lower steel column 100. Due to the limited space for hoisting the extension steel column 300, traditional lifting equipment would far exceed the available space.

[0003] Therefore, a simple and reliable steel column hoisting and installation device for the overall lifting of steel structure roofs is proposed. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a steel column hoisting and installation device for the overall lifting of a steel structure roof. The technical solution adopted by this utility model is as follows:

[0005] A steel column hoisting and installation device for integrally lifting a steel structure roof includes an extended steel column hoisted between a lower steel column and an upper steel column. Several lifting lugs are welded to both sides of the extended steel column. The device comprises a first support beam and a second support beam welded to the front and rear sides of the upper steel column, a first I-beam connected at one end to one end of the first and second support beams, a second I-beam connected at the other end of the first and second support beams, a pulley assembly slidably fitted onto the first and second I-beams and corresponding to each lifting lug, and a hoist located at the lower part of the pulley assembly. The lower part of the hoist is hung on the lifting lugs. The first and second I-beams are arranged parallel to each other.

[0006] Furthermore, the pulley assembly includes a first pulley support and a second pulley support, a connecting rod disposed between the first pulley support and the second pulley support, a lifting lug hook hung on the connecting rod, several traveling pulleys disposed on the inner sides of the first pulley support and the second pulley support, and side pulleys disposed on the first pulley support and the second pulley support; the hoist is hung on the lifting lug hook; the traveling pulleys are sleeved on the first I-beam or the second I-beam; the side pulleys are pressed against the side of the first I-beam or the second I-beam.

[0007] Furthermore, at least two of each of the lifting lugs, pulley assemblies, and hoists are provided.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] (1) This utility model provides hoisting sliding support by setting up a first support beam, a second support beam, a first I-beam and a second I-beam, welding the middle parts of the first support beam and the second support beam to the front and rear of the upper steel column respectively, and welding one end of the first I-beam and the second I-beam to the first support beam and the second support beam.

[0010] (2) By setting up a pulley assembly and a hoist, the present invention moves along the first I-beam and the second I-beam to facilitate the hoisting and moving of the extended steel column between the lower steel column and the upper steel column, thus ensuring the reliability of its hoisting.

[0011] In summary, this utility model has the advantages of simple structure and reliable hoisting, and has high practical and promotional value in the field of overall lifting and renovation technology of steel structure roofs. Attached Figure Description

[0023] like Figures 1 to 3As shown, this embodiment provides a steel column hoisting and installation device for the overall lifting of a steel structure roof, which hoists an extended steel column 300 between the lower steel column 100 and the upper steel column 200. To achieve the hoisting of the extended steel column 300, several lifting lugs 301 are welded to both sides of the extended steel column 300. Taking four lifting lugs 301 as an example, two are welded to each side. Similarly, two pulley assemblies 5 are respectively provided on the first I-beam 3 and the second I-beam 4, corresponding one-to-one with the positions of the lifting lugs 301.

[0024] Here, the steel column hoisting and installation device includes a first support beam 1 and a second support beam 2 welded to the front and rear sides of the upper steel column 200, a first I-beam 3 connected at one end to one end of the first support beam 1 and the second support beam 2, a second I-beam 4 connected at one end to the other end of the first support beam 1 and the second support beam 2, a pulley assembly 5 slidably sleeved on the first I-beam 3 and the second I-beam 4 and corresponding one-to-one with the lifting lugs 301, and a hoist 6 located at the lower part of the pulley assembly 5. The lower part of the hoist 6 is hung on the lifting lugs 301, and the first I-beam 3 and the second I-beam 4 are arranged parallel to each other. It should be noted that the distance between the first I-beam 3 and the second I-beam 4 is slightly larger than the side width of the upper steel column 200 (e.g., ...). Figure 2 (as shown), so that the pulley assembly 5 can be reliably moved to the position corresponding to the upper steel column 200.

[0025] In this embodiment, the pulley assembly 5 includes a first pulley support 51 and a second pulley support 52, a connecting rod 53 disposed between the first pulley support 51 and the second pulley support 52, a lifting lug 54 hung on the connecting rod 53, several traveling pulleys 55 disposed on the inner sides of the first pulley support 51 and the second pulley support 52, and side pulleys 56 disposed on the first pulley support 51 and the second pulley support 52. The hoist 6 is hung on the lifting lug 54. Taking the first I-beam 3 as an example, the first pulley support 51 and the second pulley support 52 are respectively placed on the two sides of the first I-beam 3, the traveling pulleys 55 are sleeved on the first I-beam 3, and the side pulleys 56 press against the sides of the first I-beam 3. In this way, the pulley assembly 5 can be slidably sleeved on the first I-beam 3 or the second I-beam 4.

[0026] In this embodiment, after the extended steel column 300 is hoisted to the lower steel column 100 and the upper steel column 200, it can be welded together, and then the first support beam 1, the second support beam 2, the first I-beam 3, the second I-beam 4 and the lifting lug 301 can be disassembled.
