DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-4 A prefabricated assembled steel structure includes a base 1 and a plurality of support rods 3. The upper end surface of the base 1 is provided with a mounting groove 2, and a mounting block 5 connected to the support rod 3 is provided in the mounting groove 2. The upper end surface of the base 1 is provided with a disassembly opening 4, which is communicated with the mounting groove 2 and corresponds to the mounting block 5. When the mounting block 5 moves to the position of the disassembly opening 4, it can move vertically to complete the separation operation from the mounting groove 2.

[0025] A cavity 9 is provided inside the mounting block 5, a slide rod 10 is provided inside the cavity 9, a sleeve plate 11 is slidably sleeved on the slide rod 10 through an extrusion mechanism, a positioning rod 6 and a pressing rod 7 are installed on the sleeve plate 11, a positioning hole corresponding to the positioning rod 6 and connected to the mounting groove 2 is provided on the upper end surface of the base 1, a screw rod 15 is provided in the cavity 9 through a supporting mechanism, a limit plate 13 is threadedly sleeved on the screw rod 15, a limit groove 8 is provided on the arc-shaped inner wall of the mounting groove 2, and the screw 15 is connected to the pressing rod 7 through a rotating mechanism.

[0026] The extrusion mechanism includes a spring 12 which is sleeved on the outside of the sliding rod 10. The two ends of the spring 12 are elastically connected to the bottom wall of the sleeve 11 and the bottom wall of the cavity 9 respectively. The elastic potential energy provided by the spring 12 realizes the support of the sleeve 11, ensuring that the positioning rod 6 and the pressing rod 7 are highly stable without external force intervention.

[0027] The supporting mechanism includes a supporting frame 14 arranged on the inner wall of the cavity 9 , and the screw rod 15 is rotatably connected to the supporting frame 14 . The supporting frame 14 is also L-shaped, which realizes stable support of the screw rod 15 in the cavity 9 .

[0028] The rotating mechanism includes a fixing ring 16 arranged on the pressing rod 7, a rack 17 is arranged on the fixing ring 16, and a gear 18 connected to the screw 15 and meshing with the rack 17 is arranged on the support frame 14. When the rack 17 moves vertically in the cavity 9, the screw 15 can be driven to rotate by the gear 18.

[0029] The vertical cross-section of the mounting groove 2 is L-shaped, and the vertical cross-section of the mounting block 5 is also L-shaped. The L-shaped design prevents the mounting block 5 from being separated from the mounting groove 2 due to vertical movement.

[0030] The limiting plate 13 is L-shaped, and the surface where the limiting plate 13 contacts the limiting groove 8 is smooth. It slides through the inner wall of the cavity 9 and extends to the outside of the mounting block 5 and into the limiting groove 8, and also plays a limiting role, increasing the stability of the mounting block 5 in the mounting groove 2.

[0031] When the utility model is used, the base 1 and the support rod 3 form a steel structure, and the support rod 3 is assembled with the base 1 by means of the mounting block 5. For details, please refer to Figure 1 In the state shown, when disassembling, the pressing rod 7 on the mounting block 5 is pressed down, and the pressing rod 7 drives the sleeve plate 11 to slide down on the slide rod 10 and compress the spring 12, and then the positioning rod 6 descends and disengages from the positioning hole. At the same time, the pressing rod 7 descends and drives the rack 17 to descend in the cavity 9 with the help of the fixing ring 16. The rack 17 can drive the gear 18 to rotate and thereby drive the screw 15 to rotate. At this time, the limit plate 13 threadedly sleeved on the screw 15 will move, and it will disengage from the limit groove 8, and then the mounting block 5 is movable relative to the base 1 and the mounting groove 2, so that the mounting block 5 moves to the position of the disassembly and assembly port 4, and then the support rod 3 and other components are lifted to complete the disassembly from the base 1.

[0032] During installation, multiple support rods 3 are stacked and placed near the disassembly and assembly port 4. The installation block 5 is inserted into the installation groove 2 through the disassembly and assembly port 4, and then slid to a fixed position. This design scheme firstly realizes the flexible disassembly and assembly of multiple components in the steel structure. Secondly, there is no need to carry the support rods 3 to other positions of the base 1, thereby improving the convenience of disassembly and assembly.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
