Description

Technical Field

[0001] The invention belongs to the technical field of steel structure construction, and particularly relates to a petal-shaped steel column turning device. Background Art

[0002] Specially shaped column is the abbreviation of special-shaped cross-section column. Here, the so-called "special-shaped cross-section" refers to the geometric shape of the column cross-section that is different from the commonly used rectangular cross-section.

[0003] Special-shaped columns are columns with varying cross-sectional geometries, such as T, L, Z, cross, and petal shapes, designed to meet structural stiffness and load-bearing capacity requirements, based on the building's intended use and design layout. These columns feature a height-to-thickness ratio of no more than 4. The limbs of special-shaped columns may be equal or unequal in length, but equal-limb special-shaped columns are recommended. Equal-limb special-shaped columns are preferred for seismic design. When unequal-limb special-shaped columns are unavoidable, the limb-to-height ratio should not exceed 1.6, and the difference in limb thickness should not exceed 50mm. "Special-shaped columns," as they are referred to in the architectural community, are characterized by thin limbs, resulting in a range of differences in component performance compared to rectangular columns, including stress, deformation, and construction methods. The regulations are primarily designed for special-shaped columns with limb thicknesses of 200 and 250mm. Their form is similar to short wall limbs; longer limbs are considered short wall limbs, making the distinction difficult to draw.

[0004] With the development of social economy and construction technology, the appearance of building structures has become more diverse, especially bionic steel structure buildings. In order to ensure the appearance of the steel structure, multiple construction processes must be carried out on the surface of the steel structure. How to provide a safe and reliable steel structure surface construction working surface for special-shaped petal-shaped steel columns has always been a technical difficulty that technical personnel in this field need to solve. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a petal-shaped steel column turning device to at least solve some of the above technical problems.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] A petal-shaped steel column turning device includes several supporting and turning mechanisms for supporting and turning the petal-shaped steel columns. The supporting and turning mechanisms include a concrete base and a petal-shaped steel column holding steel ring that is adapted to the petal-shaped steel column, is mounted on the petal-shaped steel column, and is embedded in the concrete base. The petal-shaped steel column holding steel ring is provided with a lifting hole.

[0008] Furthermore, an arc-shaped groove adapted to the petal-shaped steel column holding steel ring is opened on the concrete base, and the petal-shaped steel column holding steel ring is movably embedded in the arc-shaped groove.

[0009] Furthermore, a clamping groove adapted to the petal-shaped steel column clamping steel ring is opened on the arc surface of the arc-shaped groove, and the petal-shaped steel column clamping steel ring is clamped in the clamping groove.

[0010] Furthermore, the depth of the card slot is 5-8 cm.

[0011] Furthermore, the petal-shaped steel column holding steel ring includes a plurality of arc-shaped steel plates connected end to end, the inner ring surface of the arc-shaped steel plate is embedded with the petal-shaped steel column, and the arc-shaped steel plate is provided with the lifting hole.

[0012] Furthermore, the lifting hole coincides with the center of gravity of the curved steel plate.

[0013] Furthermore, the petal-shaped steel column clamping steel ring also includes a connecting plate, a first bolt hole is opened on the connecting plate, and second bolt holes are opened at both ends of the arc-shaped steel plate. The two adjacent petal-shaped steel column clamping steel rings are connected by the connecting plate, and the connecting plate is fixed to the petal-shaped steel column clamping steel ring by high-strength bolts passing through the first bolt hole and the second bolt hole.

[0014] Furthermore, the supporting flipping mechanisms are equidistantly distributed side by side in the length direction of the petal-shaped steel column.

[0015] Furthermore, the distance between adjacent supporting and turning mechanisms is 2-3.5m.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention has a simple structure, a scientific and reasonable design, and is easy to use. The petal-shaped steel column is clamped by a steel ring to clamp the petal-shaped steel column. The petal-shaped steel column is hung by a gantry crane through the lateral lifting holes of the steel ring to conveniently flip the petal-shaped steel column. The petal-shaped steel column can be flipped to the most reasonable posture by adjusting the lifting force of the gantry crane, thereby providing the best steel structure surface construction working surface for steel structure surface construction workers, and the flipping efficiency is high.

[0018] The present invention mainly includes a petal-shaped steel column holding steel ring and a concrete base. The concrete base is cast at equal distances along the length direction of the petal-shaped steel column. An arc-shaped groove is provided on the concrete base. A card slot is provided on the arc surface of the arc-shaped groove. The petal-shaped steel column holding steel ring includes a plurality of arc-shaped steel plates. The inner arc surface of the arc-shaped steel plate is embedded with the outer shape of the petal-shaped steel column, and the outer arc surface is a circular arc surface. When in use, the arc-shaped steel plate is embedded around the petal-shaped steel column. Adjacent arc-shaped steel plates are fixedly connected by connecting plates. The first bolt hole on the connecting plate is connected to the first bolt hole on the connecting plate. The second bolt holes on the curved steel plate are aligned, and the connecting plate and the curved steel plate are fixed by high-strength bolts. Then, the petal-shaped steel column is hoisted on the concrete base by hanging the gantry hook in the hoisting hole on the curved steel plate, and the petal-shaped steel column is tightly mounted on the steel ring in the curved groove and clamped in the clamping groove on the curved surface of the curved groove. When the surface construction surface of the petal-shaped steel column needs to be adjusted, the gantry hook is hung on the side hoisting hole, and the hoisting force of the gantry crane is adjusted to adjust the surface construction surface of the petal-shaped steel column.
