Description

Technical Field

[0001] This utility model belongs to the field of steel structure technology, specifically relating to a portal-type single-point lifting support. Background Technology

[0002] In the construction of steel roofs for large stadiums, airports, and other similar facilities, the complex nodes and high construction difficulty of the roofs often necessitate ground assembly followed by overall lifting. However, heavy steel structures are difficult to lift as a whole due to their complex structure, heavy weight, and large span. Furthermore, ensuring uniform stress and stability of the roof structure during lifting is crucial. Therefore, guaranteeing the safety and stability of heavy steel structures during lifting is a technical challenge, hence the urgent need for a portal-type single-point lifting support system to address these issues. Utility Model Content

[0003] The purpose of this invention is to propose a portal-type single-point lifting bracket to address the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a portal-type single-point lifting support, including a lattice column, a lattice column top welded to the lattice column, a steel column welded to the top of the lattice column top, a transverse main beam and a longitudinal main beam welded to the top of the steel column, two equally distributed third reinforcing ribs welded to the inner wall of the transverse main beam, and secondary beams welded to the top of the two third reinforcing ribs.

[0005] Preferably, a first diagonal bracing is welded between the top of the lattice column and the outer wall of the steel column.

[0006] Preferably, a second diagonal bracing is welded between the outer wall of the steel column and the bottom of the transverse main beam.

[0007] Preferably, a third diagonal bracing is welded between the front steel column and the rear steel column.

[0008] Preferably, the inner wall of the steel column is welded with a first reinforcing rib plate near the connection between the first diagonal brace, the second diagonal brace and the longitudinal main beam.

[0009] Preferably, a second reinforcing rib plate is welded to the inner wall of the transverse main beam near the connection point of the second diagonal brace.

[0010] Preferably, the top of the secondary beam is movably connected to a supporting steel plate by bolts, and the top of the supporting steel plate is movably connected to a hydraulic cylinder by bolts. The inner walls of both the secondary beam and the supporting steel plate are provided with through holes for steel strands that cooperate with the hydraulic cylinder.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,

[0012] (1) The lattice column is used as the support point. The support point can be flexibly arranged. At the same time, the load during the lifting process can be transferred to the steel column through the steel beam of the support, and then transferred to the lattice column through the steel column. Finally, the load is transferred to the ground, so as to achieve uniform and stable force transmission of the heavy steel structure during the lifting process. Attached Figure Description

[0018] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a portal-type single-point lifting support, including a lattice column 1, a lattice column top 2 welded to the lattice column 1, a steel column 4 welded to the top of the lattice column top 2, a transverse main beam 6 and a longitudinal main beam 12 welded to the top of the steel column 4, two equally distributed third reinforcing ribs 9 welded to the inner wall of the transverse main beam 6, and secondary beams 14 welded to the top of the two third reinforcing ribs 9. It should be noted that the lattice column 1 is provided in two sets, and H-shaped steel is pre-embedded between the two sets of lattice column 1 for connection, so that the lattice column 1 is connected to each other by tie rods to form a stable frame system.

[0020] Furthermore, a first diagonal bracing 3 is welded between the top of the lattice column 2 and the outer wall of the steel column 4, and a third diagonal bracing 11 is welded between the front steel column 4 and the rear steel column 4. This facilitates the reinforcement and support between the lattice column 2 and the steel column 4, as well as between the steel columns 4, to prevent lateral deformation during the lifting process.

[0021] Furthermore, a second diagonal brace 5 is welded between the outer wall of the steel column 4 and the bottom of the transverse main beam 6, which facilitates the reinforcement and support between the steel column 4 and the transverse main beam 6 to prevent the main beam from deflecting during the lifting process. Specifically, the bottom of the diagonal brace 5 is fixed in the middle of the steel column 4. It should be noted that when setting the lattice column 1, the height of the lattice column 1 should be ensured to avoid the situation where the setting of the diagonal brace 5 hinders the operation of the hydraulic lifting device.

[0022] The above structural design enhances the rigidity and structural strength of the lifting support, effectively preventing the dangerous situation of the transverse main beam 6 breaking during operation.

[0023] Furthermore, the inner wall of the steel column 4 is welded with a first reinforcing rib plate 7 near the connection between the first diagonal brace 3, the second diagonal brace 5 and the longitudinal main beam 12, and the inner wall of the transverse main beam 6 is welded with a second reinforcing rib plate 8 near the connection between the second diagonal brace 5. This increases the rigidity and strength of the structure during the lifting process, improves the stability and load-bearing capacity of the lifting support, and further reduces the deformation and deflection of the steel column 4 and the transverse main beam 6 during the lifting process.

[0024] Furthermore, a support steel plate 15 is movably connected to the top of the secondary beam 14 by bolts, and a hydraulic cylinder 10 is movably connected to the top of the support steel plate 15 by bolts. The inner walls of both the secondary beam 14 and the support steel plate 15 are provided with steel strand through holes 13 that cooperate with the hydraulic cylinder 10.

They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
