The clamping plates 8 and the fixed sleeve 7 are an integral structure. The connection between the two is elastic and deformable. A deformation gap 9 is provided between two adjacent clamping plates 8, and the plurality of clamping plates 8 and the deformation gap 9 form a virtual conical structure. An external thread is provided on the outer wall of the fixed sleeve 7, and is threadedly connected with the cylindrical cavity in the mounting sleeve 5, so that the clamping plates 8 extend into the truncated cone-shaped cavity in the mounting sleeve 5, and the truncated cone-shaped cavity squeezes the clamping plates 8 to clamp the steel pipe column 1.

[0029] The bottom of the installing sleeve 5 is threadedly matched with the fixing sleeve 7 so that the truncated cone-shaped cavity in the installing sleeve 5 squeezes the clamping piece 8 so that the steel pipe column 1 is tightly clamped, thereby realizing the connection and fixation between the connecting plate 3 and the steel pipe column 1. The disassembly is also relatively simple, and the installing sleeve 5 can be directly rotated to gradually move up and away from the fixing sleeve 7; the steel pipe columns 1 can be neatly stacked, space can be saved, and transportation is convenient.

[0030] Embodiment 2: Combining with Figure 2 , 3 .

[0031] The connecting head 4 includes a mounting portion 15 and a second connecting portion 10 , wherein the mounting portion 15 is a threaded column, and the end of the steel pipe cross beam 2 is provided with a thread and cooperates with the mounting portion 15 , and the second connecting portion 10 cooperates with the first connecting portion 6 .

[0032] The connecting part 1 6 is a trapezoidal block structure with a narrow upper end and a wide lower end, and the connecting part 2 10 is a trapezoidal groove structure with a narrow upper end and a wide lower end. The connecting part 1 6 is inserted into the connecting part 2 10 .

[0033] The cross-sections of the connecting portion 1 6 and the connecting portion 2 10 are also trapezoidal, and are narrower at the side close to the steel pipe column 1 and wider at the end away from the steel pipe column 1 .

[0034] The connecting portion 1 6 and the mounting sleeve 5 are an integral structure, and the mounting portion 15 and the connecting portion 2 10 are an integral structure.

[0035] The connecting head 4 is detachably installed on the steel tube beam 2. Since the steel tube column 1 and the steel tube beam 2 usually use steel tubes with the same diameter, this design allows the connecting head 4 to be removed and the steel tube beam 2 to be used as a column. There is no need to distinguish between the column and the beam, which is convenient to use.

[0036] By cooperating the trapezoidal block-shaped connecting part 16 with the trapezoidal groove-shaped connecting part 2 10, it is convenient to install and connect them, and the connection between the two becomes tighter and tighter under the action of gravity. By setting the cross-section of the connecting part 1 6 and the connecting part 2 10 to a horizontal trapezoid, the steel pipe crossbeam 2 can be fixed in the horizontal direction, and the connecting part 1 6 and the connecting part 2 10 can be moved and separated in the horizontal direction.

[0037] Embodiment 3: Combining with Figure 3 , 6 .

[0038] The steel pipe column 1 is provided with a plurality of limiting grooves 11 from top to bottom, and the inner side of the clamping piece 8 is provided with a limiting protrusion 12 , which can be inserted into the limiting groove 11 .

[0039] By setting the limiting groove 11 and the limiting protrusion 12, the fixing sleeve 7 can be initially fixed, so as to avoid the fixing sleeve 7 from shifting up and down when the connecting plate 3 is installed, thereby affecting the installation and assembly of the scaffolding.

[0040] Embodiment 4: Combining with Figure 4 , 5 、6.

[0041] The fixing sleeve 7 and the installation sleeve 5 are both provided with an inserting groove 13 on their side walls, and a handle 14 is inserted inside.

[0042] By inserting the handle 14 into the insertion groove 13, the torque is increased to make the two easier to rotate. The handle 14 on the fixed sleeve 7 is held by hand to rotate the handle 14 on the installation sleeve 5 so that the two rotate relative to each other, thereby making the two threadedly connected.

[0043] When the utility model is implemented, the fixing sleeve 7 is sleeved on the outside of the steel pipe column 1 and moved up and down. During the up and down movement, the limiting protrusion 12 on the clamping piece 8 is squeezed, causing the clamping piece 8 to deform outward. When it moves to a suitable height, the fixing sleeve 7 is rotated to align the limiting protrusion 12 with the limiting groove 11. Under the elastic action of the clamping piece 8 and the fixing sleeve 7, the limiting protrusion 12 is inserted into the limiting groove 11 to achieve the initial fixation of the fixing sleeve 7. Then, the installation sleeve 5 is sleeved on the outside of the steel pipe column 1 from the fixing sleeve 7, so that the clamping piece 8 extends into the installation sleeve 5, and then the handle 14 is inserted into the insertion groove 13. The installation sleeve 5 is rotated. Since the installation sleeve 5 is threadedly matched with the fixing sleeve 7, it is inconvenient to fix the fixing sleeve 7. When the mounting sleeve 5 is rotated, it will gradually descend, so that the clamping piece 8 is squeezed by the truncated cone-shaped cavity inside the mounting sleeve 5, thereby clamping the steel pipe column. Then, after the mounting part 15 of the connecting head 4 is connected to the end of the steel pipe beam 2, the larger opening at the bottom of the connecting part 2 10 is moved downward from the top of the connecting part 1 6, so that the connecting part 1 6 is inserted into the connecting part 2 10 to achieve the connection and installation of the two. When disassembling, first lift the steel pipe beam 2 upward to separate the connecting part 1 6 from the connecting part 2 10, and then rotate the mounting sleeve 5 in the opposite direction to move it upward. Under the elastic force of the connection between the clamping piece 8 and the fixed sleeve 7, the clamping piece 8 is loosened, and the fixed sleeve 7 is moved up and down to squeeze the limiting protrusion 12 and leave the limiting groove 11, so that the fixed sleeve 7 can be removed.

[0044] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
