For steel components with a large number of structural units, the number of bolted connectors is large and of varying sizes, making assembly of the steel components difficult. Bolted connectors are easily lost, resulting in insecure connections between structural units and compromising the structural strength of the steel components. Summary of the Invention

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0041] See also Figure 1-7 On the one hand, the present invention provides an assembled steel member, comprising: a base 1, an arc-shaped I-beam 2 and a channel steel 3. The base 1 is annular, and a plurality of plug-in grooves 11 are provided on the inner wall of the base 1. A notch 12 is also provided on the inner wall of the base 1. The bottom of the notch 12 extends to the plug-in groove 11. A plurality of arc-shaped I-beams 2 arranged circumferentially are provided on the base 1. A hanging plate 21 is provided at the bottom of the arc-shaped I-beam 2. The hanging plate 21 is plugged into the plug-in groove 11. The arc-shaped I-beam 2 is clamped into the notch 12. The web of the arc-shaped I-beam 2 is provided with a plurality of slots arranged along its own length. A through hole 22 is provided on the curved I-beam 2. At least one channel steel support layer is provided. The channel steel support layer includes a plurality of curved channel steels 3. The channel steels 3 and the curved I-beam 2 are arranged at intervals. The channel steels 3 are inserted between the two flange plates of the curved I-beam 2. The ends of the channel steels 3 are detachably connected to the web of the curved I-beam 2 via a locking assembly 4. The locking assembly 4 includes a center rod 41 and locking blocks 42. The center rod 41 is passed through the through hole 22. The locking blocks 42 are symmetrically arranged at both ends of the center rod 41. The locking blocks 42 are threaded onto the center rod 41 and contact the inner wall of the channel steel 3. The locking blocks 42 are specifically circular to facilitate rotational support of the channel steel 3. A regular hexagonal protrusion is provided on one side of the locking block 42 to facilitate rotational locking.

[0042] The base 1 is provided with an extension edge 13 extending outward along the outer peripheral surface. The provision of the extension edge 13 can increase the bottom diameter of the base 1, increase the weight of the base 1, lower the center of gravity of the assembled steel member, and make the assembled steel member less likely to tip over.

[0043] The radius of the extended edge 13 is greater than or equal to the distance from the top of the curved I-beam 2 to the axis of the base 1. The top of the curved I-beam 2 will not exceed the outer periphery of the extended edge 13, which can clearly define the installation space required for the prefabricated steel structure and avoid collision damage to the end of the curved I-beam 2 during installation.

[0044] A reinforcement block 14 is provided on the extension edge 13. The reinforcement block 14 is detachably mounted on the extension edge 13, with one end of the reinforcement block 14 resting against the side surface of the base 1. The reinforcement block 14 can be made of a metal block to achieve counterweight, further lowering the center of gravity of the assembled steel structure, making it less likely to tip over.

[0045] The reinforcement block 14 is plugged into the extension edge 13 to facilitate disassembly, replacement, and position adjustment.

[0046] An annular rod layer is also provided on the curved I-beam 2. This layer comprises several curved metal rods 5, which are inserted through through-holes 22. Connecting sleeves 6 are provided between adjacent metal rods 5. The ends of the metal rods 5 are inserted into the connecting sleeves 6, which are curved tubular structures. The annular rod layer fills the through-holes 22 and assists in positioning and supporting the curved I-beam 2, thereby enhancing the structural strength of the assembled steel structure.

[0047] The annular rod layer includes three arc-shaped metal rods 5, which reduces the number of the arc-shaped metal rods 5 and improves the strength of the annular rod layer.

[0048] A support rod 61 is provided on the back of the connecting sleeve 6. The support rod 61 is hinged to the reinforcement block 14, and the connecting sleeve 6 is fixedly mounted on the end of the support rod 61. The provision of the support rod 61 further utilizes the base 1 to support the annular rod layer, thereby improving the integrity of the assembled steel structure and increasing the overall strength of the assembled steel structure.

[0049] On the other hand, the present invention also provides a method for processing the above-mentioned assembled steel member, comprising the following steps:

[0050] S1. Fix the base 1 on the base. The base is a steel structure that needs a specific installation location, such as the ground or rooftop.

[0051] S2, insert the arc-shaped I-beam 2 into the base 1 through the mounting plate 21 in sequence;

[0052] S3. Install the locking assembly 4 in the through hole 22 of the arc-shaped I-beam 2;

[0053] S4. Install the channel steel 3 between two adjacent curved I-beams 2. The cross-section of the channel steel 3 is "C"-shaped. The specific process includes: removing the locking block 42 on one side of the web of the curved I-beam 2, and pulling the center rod 41 backward so that there is no protrusion between the two flange plates of the curved I-beam 2. Then, insert the end of the channel steel 3 between the two flange plates of the curved I-beam 2, with the notch of the channel steel 3 facing the outside of the base 1, and adjust the height of the channel steel 3 so that the center rod 41 is pushed forward and then extends into the inside of the channel steel 3. Then, install the locking block 42 into the channel steel 3 through the notch of the channel steel 3, and slide the locking block 42 along the groove of the channel steel 3. Fix the locking block 42 to the center rod 41 again, and the locking block 42 contacts the inner wall of the channel steel 3.

[0054] S5. Install multiple channel steels 3 of the same height to form a channel steel support layer, and complete the assembly of the prefabricated steel components.

[0055] Working Principle: During the assembly of prefabricated steel components, the base 1 and the curved I-beam 2 are fixed by plugging, and the two ends of the curved I-beam 2 are fixed by the base 1 and the channel steel support layer respectively. In the channel steel support layer, the channel steel 3 and the curved I-beam 2 are detachably connected via a locking assembly 4. Specifically: The locking block 42 supports the channel steel 3 to lock the position of the channel steel 3 in the vertical direction, and the two flange plates of the curved I-beam 2 lock the front and rear positions of the channel steel 3 to fully position it. This simplifies the connection method of prefabricated steel components, reduces assembly difficulty, improves assembly efficiency, and uses damage-free connections between component units for easy reuse.

[0056] The prefabricated steel structure can be provided with several layers of channel steel support layers as required. Ring rod layers can be installed at the through holes 22 where channel steel support layers are not installed. The ring rod layers not only further enhance the structural strength of the prefabricated steel structure, but also facilitate the installation of other objects on the prefabricated steel structure.
