Each first fixed rod 11 has a first insertion channel 111 extending axially along the first fixed rod 11 and adapting to the first movable rod 13. Each first fixed rod 11 has a predetermined number of first connecting through holes 110 radially penetrating the first fixed rod 11 and communicating with the first insertion channel 111. The first movable rod 13... A preset number of second connecting through holes 130 are provided, each of which radially penetrates the first movable rod 13. When the first movable rod 13 is inserted into the first insertion channel 111 of the first fixed rod 11, and the first connecting through hole 110 at a preset position on the first fixed rod 11 aligns with the second connecting through hole 130 at a preset position on the first movable rod 13, bolts pass through the first connecting through hole 110 and the second connecting through hole 130 respectively, thereby detachably connecting the first fixed rod 11 and the first movable rod 13 together. Thus, when it is necessary to adjust the depth of the first movable rod 13 inserted into the first insertion channel 111 of the first fixed rod 11, it is only necessary to move the first movable rod 13 so that the second connecting through hole 130 at a preset position on the first movable rod 13 aligns with the first connecting through hole 110 on the first fixed rod 11, and then bolts are inserted into the first connecting through hole 110 and the second connecting through hole 130, thereby changing the overall length of the first fixed rod 11 and the first movable rod 13 connected together. The overall length can be changed promptly as needed.

[0026] In some embodiments of this application, please refer to Figure 1-5The first support assembly 1 further includes a predetermined number of first docking blocks 14.

The second fixed rod 21 has a second insertion channel 211 extending axially along the second fixed rod 21 and is adapted to the second movable rod 23. The second fixed rod 21 is provided with a predetermined number of fourth connecting through holes 210, which radially penetrate the second fixed rod 21 and communicate with the second insertion channel 211. The second movable rod 23... A predetermined number of fifth connecting through holes 230 are provided, the fifth connecting through holes 230 radially penetrating the second movable rod 23; when the second movable rod 23 is inserted into the second insertion channel 211 of the second fixed rod 21, and the fourth connecting through hole 210 at a predetermined position on the second fixed rod 21 is aligned with the fifth connecting through hole 230 at a predetermined position on the second movable rod 23, bolts pass through the fourth connecting through hole 210 and the fifth connecting through hole 230 respectively, thereby making the second fixed rod 21 and the second movable rod 23 detachably connected together. Thus, when it is necessary to adjust the depth of the second movable rod 23 inserted into the second insertion channel 211 of the second fixed rod 21, it is only necessary to move the second movable rod 23 so that the fifth connecting through hole 230 at the preset position on the second movable rod 23 is aligned with the fourth connecting through hole 210 on the second fixed rod 21. Then, the rod is bolted into the fourth connecting through hole 210 and the fifth connecting through hole 230, thereby changing the length of the whole formed by the second fixed rod 21 and the second movable rod 23 connected together. The length of the whole can be changed in time according to the needs.

[0029] In some embodiments of this application, please refer to Figure 1-5 The second support component 2 further includes a predetermined number of second docking blocks 24.

The eighth connecting through hole 31 extends radially through the head end of the connecting pipe 3, and the ninth connecting through hole 32 extends radially through the tail end of the connecting pipe 3.

[0032] In some embodiments of this application, please refer to Figure 1-5 The steel frame also includes binding ropes 4, which tension the adjacent connecting pipes 3 together laterally. In this application, "tensioned connection" means that one end of the binding rope 4 is connected to one of the two adjacent connecting pipes 3, and the other end of the binding rope 4 is connected to the other of the two adjacent connecting pipes 3, and the binding rope 4 is under tension. This improves the stability of the entire steel frame.

[0033] In summary, when the first support assembly is located at the top of the steel frame, the first mating block on the first movable rod of the first support assembly mates with the head end of the connecting pipe, and the third connecting through hole on the first mating block aligns with the eighth connecting through hole on the head end of the connecting pipe. Then, bolts are inserted into the third connecting through hole and the eighth connecting through hole respectively, thereby detachably connecting the first support assembly and the connecting pipe. When the first support assembly is located at the bottom of the steel frame, the first mating block on the first movable rod of the first support assembly mates with the tail end of the connecting pipe, and the third connecting through hole on the first mating block aligns with the ninth connecting through hole on the tail end of the connecting pipe. Then, bolts are inserted into the third connecting through hole and the ninth connecting through hole respectively, thereby detachably connecting the first support assembly and the connecting pipe. The second docking block of the second support assembly docks with two adjacent connecting pipes in the longitudinal direction. The sixth and seventh connecting through holes on the second docking block are aligned with the ninth connecting through hole at the tail end of one of the two adjacent connecting pipes and the eighth connecting through hole at the head end of the other of the two adjacent connecting pipes, respectively. Then, the connecting pipes are detachably connected to the second docking pipe by bolts, so that the connecting pipes are detachably connected to the second support assembly.

[0034] The easily assembled and disassembled stairwell steel frame provided in this application has advantages in structure and rapid assembly and disassembly. Furthermore, given the inclusion of a first support component, a second support component, and connecting pipes, with both the first and second support components detachably connected to the connecting pipes, the lengths of the first and second support components can be adjusted to meet the labor requirements of irregularly shaped sites. Additionally, the presence of binding ropes between adjacent connecting pipes in the lateral direction enhances the overall stability of the steel frame. Moreover, the steel frame provided in this application can be mass-produced and installed on-site, greatly improving construction efficiency, saving costs, and ensuring safe construction operations.
