DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figure 1-Figure 3 The quick docking node of the upper and lower steel columns shown in the figure includes a positioning block 10 and a connecting piece. Figure 4-Figure 6 As shown, the upper and lower steel columns include a first steel column 20 and a second steel column 30 to be butted together; the side wall of the first steel column 20 is provided with four first ear plates 21 at intervals along the circumferential direction; the side wall of the second steel column 30 is provided with four second ear plates 31 at intervals along the circumferential direction, and the second ear plates 31 correspond to the first ear plates 21 in their respective positions.

[0021] The positioning block 10 includes a first clamping portion 11 and a second clamping portion 12; the first clamping portion 11 is provided with a first positioning groove 14, and the second clamping portion 12 is provided with a second positioning groove 15; the first clamping portion 11 clamps the first ear plate 21 in the first positioning groove 14, and a connecting member connects the first clamping portion 11 and the first ear plate 21; the second clamping portion 12 clamps the second ear plate 31 in the second positioning groove 15. The second clamping portion 12 is provided with a guide portion 13 at one end facing away from the first clamping portion 11; the second positioning groove 15 penetrates the guide portion 13, and the distance between the second positioning groove 15 of the guide portion 13 and the inner wall gradually increases in the direction away from the first clamping portion 11. In this embodiment, the first clamping portion 11, the second clamping portion 12 and the guide portion 13 are an integrated structure.

[0022] The positioning block 10 is made of high-strength, wear-resistant and corrosion-resistant materials to ensure its stability and reliability during the docking process. Through cutting, drilling, milling and other processing steps, the positioning block 10 reaches a rough shape and size, and the distance between the left and right walls of the second positioning groove 15 of the guide part 13 gradually increases from top to bottom, that is, the distance between the relative inner walls of the second positioning groove 15 of the guide part 13 gradually increases in the direction away from the first clamping part 11 to ensure the process of progressive docking. This progressive design allows the cooperation between the second ear plate 31 and the positioning block 10 to be gradually adjusted from a wider state to a narrower state that matches the second clamping part 12 during docking, which can improve the efficiency and speed of docking. Compared with one-time adjustment, progressive placement can be gradually adjusted according to actual conditions, reducing the time of repeated adjustments and debugging, and improving the efficiency and smoothness of construction.

[0023] In some embodiments, the two opposite inner walls of the first positioning groove 14 of the first clamping portion 11 of the positioning block 10 are rougher than the two opposite inner walls of the second positioning groove 15. Therefore, the contact surface between the first clamping portion 11 and the first ear plate 21 is relatively rough, so that no relative displacement occurs when the first clamping portion 11 is fixed. The contact surface between the second clamping portion 12 and the second ear plate 31 should be relatively smooth, and lubricants can be applied when necessary to ensure rapid docking, gradual positioning, and smooth docking.

[0024] The first positioning groove 14 passes through the geometric center of the first clamping part 11 along the length direction of the positioning block 10, and the second positioning groove 15 passes through the geometric center of the second clamping part 12 along the length direction of the positioning block 10. The positioning block 10 can be regarded as having slots at its upper and lower ends, the slot at the upper end is the first positioning groove 14, the slot at the lower end is the second positioning groove 15, and the lower end of the second positioning groove 15 is ground and chamfered to form the guide part 13. The length directions of the positioning block 10, the first ear plate 21, the second ear plate 31, the first section steel column 20, and the second section steel column 30 are all the same.

[0025] The thickness of the first ear plate 21 is smaller than or equal to the width of the first positioning groove 14 , and the thickness of the second ear plate 31 is smaller than or equal to the width of the second positioning groove 15 .

[0026] The first ear plate 21 is provided with an ear plate connecting hole 22; the first clamping portion 11 is provided with a clamping portion connecting hole passing through the first positioning groove 14; the connecting member passes through the clamping portion connecting hole and the ear plate connecting hole 22 to connect the first ear plate 21 and the first clamping portion 11. The connecting member includes a matching screw rod 16 and a nut 17; one end of the screw rod 16 passes through the clamping portion connecting hole and the ear plate connecting hole 22 and is connected to the nut 17.

[0027] The first ear plate 21 is provided with a plurality of ear plate connecting holes 22 , which are arranged at intervals along the length direction of the first ear plate 21 . The length direction of the first ear plate 21 is the same as the length direction of the first section steel column 20 .

[0028] In some embodiments, the second ear plate 31 has the same structure as the second ear plate 31, except that the first ear plate 21 is disposed on the first steel column 20, and the second ear plate 31 is disposed on the second steel column 30. In fact, the structures of the first steel column 20 and the second steel column 30 can be completely the same. Therefore, the docking of the first steel column 20 and the second steel column 30 only requires the use of four positioning blocks 10 and connectors to achieve the docking of the first ear plate 21 and the second ear plate 31.

[0029] In this embodiment, the upper and lower steel column quick docking nodes are constructed. Figure 4-Figure 6 As shown, first, ensure that the connection surfaces of the upper and lower sections of the steel columns are clean and flat, without any debris or protrusions.

[0030] The positioning block 10 is mounted on the first ear plate 21 of the first steel column 20 through a connecting piece, so that the second positioning groove 15 of the positioning block 10 faces the second steel column 30 to be docked.

[0031] The first steel column 20 is slowly lowered to gradually contact the second steel column 30 below. During the lowering process, the contact between the positioning block 10 and the second steel column 30 is observed.

[0032] If the docking position needs to be adjusted, the position of the positioning block 10 can be adjusted by loosening the nut 17 so that it can adapt to the position of the second section of the steel column 30 .

[0033] The first steel column 20 is continuously lowered until the second positioning groove 15 of the positioning block 10 is completely docked with the second ear plate 31 of the second steel column 30 , that is, the second ear plate 31 is inserted into the second positioning groove 15 .

[0034] Ensure that the positioning block 10 is tightly fixed between the upper and lower steel columns to provide stable support.

[0035] After ensuring that the upper and lower sections of the steel column are correctly butted against each other, use an appropriate tool (such as a wrench or a torque wrench) to gradually tighten the nut 17 on the screw rod 16 to ensure that the positioning block 10 is securely fastened.

[0036] After the docking is completed, the connector and the positioning block 10 are finally checked to ensure that the nut 17 is not loose, the screw rod 16 is not broken or deformed, and the contact between the positioning block 10 and the first section of the steel column 20 is tight.

[0037] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
